Definitions

  • the present invention relates to a security system for a trolley of a crane, wherein the trolley is movably mounted on a guide surface of the crane, comprising a braking device for braking the trolley, and a triggering device for triggering the braking device.
  • Cranes are generally used whenever loads have to be lifted and moved.
  • a typical application is building construction.
  • loads must be transported quickly and flexibly to the places where they are needed for use.
  • heavy loads over several ten to a hundred meters are transported in height, for example, construction equipment or building materials such as sand or cement.
  • tower cranes which comprise a substantially vertically extending tower and an attached, substantially horizontally extending boom.
  • a guide surface on which the trolley is movable along the boom For this purpose, the trolley rollers and is moved by means of so-called trolley cables.
  • the trolley cables are tightened with a drivable drum, one of which winds up while the other unwinds, if a corresponding force acts.
  • a drivable drum on the load cables, to which the loads to be transported are attached can be rolled up and unrolled.
  • the tilting moment acting on the crane must not be too great otherwise he can tilt or even tip over.
  • the heavier the load the less far from the tower it may be moved by means of the trolley along the boom.
  • the loads must not be moved too fast, otherwise they will oscillate too much and their kinetic energy becomes too large and thus difficult to control.
  • a special danger when transporting is based on a breakage of the trolley rope.
  • the arms are, as indicated above, arranged substantially horizontally, but never exactly horizontal. If the trolley rope breaks, the trolley can move uncontrollably along the boom. If heavy loads are attached to the trolley, a slight deviation from the horizontal is sufficient to accelerate the trolley. In this case, the case may occur that the trolley moves in the direction of the tower, where depending on the design of the crane operator. If the trolley moves uncontrollably towards the tower, it or the load hanging on it can injure the crane driver on the one hand and, on the other hand, drive the load into the tower, which can cause serious damage to the load and the tower and injuries to the crane driver.
  • the even more critical case may occur that the trolley moves in the direction of the free, the tower facing away from the end of the boom. With increasing distance of the load from the tower, the tilting moment acting on the crane increases, so that the boom inclines more and more out of the horizontal, whereby the downhill force acting on the trolley becomes larger and the trolley is accelerated more and more. The trolley moves faster and faster to the free end of the boom and the crane threatens to tip over. Such situations pose serious risks to the persons in the vicinity of the crane.
  • a disadvantage of such security systems is that the lever abruptly abuts against a carrier and thus the trolley is braked abruptly. Firstly, in such situations, the bending moment acting on the lever exceeds the permissible bending moment many times, so that there is a great danger that the lever will be torn and damaged out of its anchorage, thus rendering the safety system ineffective. On the other hand, the abrupt deceleration of the trolley causes the loads hanging on it to swing heavily, again posing a threat to the stability of the crane and the people around the crane.
  • the object of the invention is therefore to develop the safety system of the type mentioned so that it causes a safe deceleration of the trolley in the event of breakage of the trolley without the adverse effects described above occur. Furthermore, the security system should be easy to assemble and robust and reliable.
  • the object is achieved by a security system according to claim 1.
  • the trolley is braked by means of a frictional connection between the braking device and the guide surface.
  • the trolley is not abruptly, but gently braked, as is the case with known solutions.
  • the oscillations are reduced, which are induced in the deceleration of the hanging on the trolley loads, whereby the reliability of the crane is increased.
  • the risk of failure of the brake device compared to known solutions is significantly lower: Compared to the The lever described above, which is used in the prior art for braking the trolley in the event of breakage of the trolley rope and the trolley brakes by means of positive engagement occur in the brake device according to the invention no loads that could lead to the destruction of the brake device.
  • the reliability of the crane will be further increased. No components are damaged, so that, except for the broken cat rope, no further components need to be replaced or repaired.
  • the brake device comprises a brake wedge and one or more counter wedges.
  • the design of the brake device as a wedge brake has the advantage that with simple and robust means very high forces between the brake device and the guide surface can be transmitted. Furthermore occurs in wedge brakes on a self-locking. The heavier the loads and the greater the kinetic energy of the loads, the stronger the brake wedge and the counter wedge are pushed into each other and increases the force acting between the brake device and the guide surface force. An overload of the braking device according to the invention can therefore be largely excluded.
  • the brake wedge and the counterwedge are arranged in a caliper which is connected to the trolley.
  • the braking device is combined into a compact unit that can be easily mounted on any existing trolley. Special conversion measures are not required, so that the existing trolleys can be retrofitted in a simple and cost-effective manner.
  • the counter wedge is releasably attachable to the caliper. This is preferably achieved by screws. As a result, the mountability of the braking device is facilitated, furthermore, in the event that the braking device has been triggered and the brake wedge and the counter wedge are wedged into each other, they are easily separated from each other and the braking device to be used again.
  • the braking device according to the invention thus increases the sustainability of the security system.
  • the brake wedge is releasably fixed to the brake caliper by means of a fixing device, wherein the fixing device can be activated to release the fixation of the brake wedge by means of the triggering device.
  • the fixing device can be activated to release the fixation of the brake wedge by means of the triggering device.
  • inclination and speed sensors can be used as the triggering device. If the boom of the crane tend to be over a permissible level, the mobility of the trolley can be prevented, even if the trolley rope is not broken. The same can be done when the trolley is moving at a speed higher than a maximum permissible value, even if the trolley rope is not broken. This case could occur when the gearbox breaks the drum with which the trolley rolls along the trolley Guide surface is moved on the boom.
  • the triggering device may be remotely controllable, so that the crane operator can activate the braking device as soon as he recognizes a critical situation and he is of the opinion that other possibly existing braking devices can no longer have a sufficient effect on the trolley.
  • any device can be used which fixes the brake wedge and cancels the fixation in dependence on a determinable event.
  • the fixing device can act mechanically, for example in the form of a pawl, or electrically, for example by means of a magnet. A combination of both modes of action is also conceivable.
  • the fixing device comprises a bolt which is movable relative to the brake wedge by means of the triggering device, so that the fixation of the brake wedge on the brake caliper can be released.
  • the fixation of the brake wedge on the caliper by means of a bolt is structurally simple and has proven to be robust and reliable.
  • the bolt is preferably made of a stainless steel.
  • the leadership of the bolt is also made of a stainless material. Since cranes are used almost exclusively outdoors and are therefore exposed to the weather unprotected, this form of fixation is particularly advantageous.
  • the brake wedge has a brake pad for increasing the friction between the brake wedge and the guide surface.
  • the crane is exposed to the weather unprotected.
  • the friction on the guide surface is reduced, such as by moisture or ice.
  • the brake pad is provided, which has a corresponding surface finish.
  • the brake pad is releasably connectable to the brake wedge.
  • This design simplifies assembly. Furthermore, it is possible to use for the brake pad another material with the appropriate surface finish, without the entire brake wedge would have to be made of this material. If the brake device has been triggered several times, the brake pad can be quickly and easily replaced with a new brake pad to eliminate the wear caused by the braking operations of the brake pad. It can thus be provided the required friction without the entire brake wedge would have to be replaced.
  • the tripping device can be activated with the first or second trolley rope.
  • the braking device is activated, for example, when the first or second trolley rope breaks.
  • the trolley rope with markings be detected, which are detected by a cooperating with a controller sensor, which can determine the speed with which the first or the second trolley rope moves. If the sensor detects a speed that is above the permissible maximum value, the braking device can be activated.
  • the triggering device and the fixing device are connected by means of a cable, wherein the fixing device can be activated by pulling the cable.
  • the fixing device can be activated by pulling the cable.
  • the activation in the case of a particular event can be easily realized, for example by means of a motor that attracts the cable.
  • This type of activation is inexpensive, robust and reliable and can be easily manufactured and assembled.
  • the triggering device has a lever rotatable about a rotation axis, which holds by means of the first or second trolley rope, the triggering device in a starting position in which the fixing device is not activated, wherein the cable is attracted by means of the lever.
  • the lever comes into contact with the first or second trolley rope, whereby it can only rotate within the deflections of the trolley cable induced by fluctuations in the tension of the trolley cable.
  • these small rotations which can perform the lever, do not trigger the brake device.
  • the fixing device and thus the braking device are only triggered when the first or the second trolley rope breaks.
  • the lever can rotate freely and triggers the braking device.
  • This embodiment is particularly simple in construction and thus robust and reliable.
  • the brake device is triggered only in the case when the trolley rope actually breaks.
  • the lever has a first portion and a second portion, wherein on the first portion of a mass piece is arranged and the trolley rope passes through the second portion and holds the triggering device in the starting position.
  • the mass piece causes the lever with the second portion to contact the trolley rope. If the first or second trolley rope breaks, the mass will cause the lever to rotate immediately after the trolley rope breaks.
  • the brake device is thus activated immediately after breakage of the trolley rope, so that the trolley is stopped quickly. Long acceleration times are therefore not possible, so that the loads can not be accelerated to dangerous speeds. The danger for the people in the vicinity of the crane is thus significantly reduced.
  • the triggering device comprises a movable relative to a counter plate sliding plate which is biased by means of springs.
  • the triggering device can be made compact, so that it can also be arranged in environments in which little space is available.
  • the sliding plate is further movable by means of a guide piece relative to the counter plate, wherein the trolley rope can be connected to the guide piece and the counter plate can be prestressed by means of the trolley rope.
  • the number of additional components can be kept low in this embodiment, which increases the mountability and the robustness of the triggering device.
  • the object is achieved by means of a crane, in particular a tower crane, which comprises a safety system according to one of the previous embodiments.
  • a crane in particular a tower crane, which comprises a safety system according to one of the previous embodiments.
