State of the art

By reviewing the patent and non-patent documents, the inventor is not aware of similar solutions of devices for joining/separating pipes. Joining/separating pipes, until now, was mostly done manually, with smaller diameter pipes, with the help of levers, hammers, etc. hand tools, and for pipes of larger diameter and weight, with the help of construction machines, excavators, bulldozers, tractors. The main disadvantage of the described methods is that such handling often resulted in destruction or damage, especially to pipes made of fragile and fragile materials, for example. ceramics, PVC and fiberglass epoxy materials. In addition to the apparent material damage, the disadvantage is that the described procedures took a long time and, in addition to the use of machinery, involved the participation of a large number of workers.

Presentation of the essence of the invention

The invention relates to a device for joining/separating pipes. The device consists of two pipe clamps with a tensioner, two locking mechanisms with toothed racks, tensioning levers and other accessories.

The device for connecting/separating pipes, according to this invention, consists of two clamps, made of steel strips with a tensioner. Each of the clamps is placed on the end of two pipes. One on the pipe that is being pulled in, and the other on the pipe that the previous pipe is being fed into. Each of the clamps has two hooks, attached to the rim, at an angle of 90° to the tensioner. A locking mechanism with a toothed rack is attached to each of its side hooks on the clip that includes the retractable/retractable tube. A pusher is attached to the end of each rack. In the groove of each pusher, a tension lever is attached, with the help of a screw, which has a built-in hook at the other end. Another tension lever is attached to its hook with its own hook. The second tension lever at its other end also has a derived hook which engages a hook on the barrel clamp into which the previous barrel is fed.

The advantages of this solution of the device for connecting/separating pipes are reflected in the following:

- the time for positioning the device on the pipe is very short;

- the procedure for positioning the device on the pipe is very simple;

- the procedure for connecting/separating pipes requires only two executors;

- it is not necessary to hire heavy machinery;

- two executors connect/separate pipes in only 60 seconds;

- there is no risk of damage (destruction) of the pipe;

- the device is applicable for a large range of pipe diameters;

- the costs of making the device are very low;

- the device is applicable for all types of pipe materials to be joined/separated;

Detailed description of the invention

The device for joining/separating pipes, according to the present invention and the accompanying drawings, consists of two clamps 2 which are placed on the ends of the pipes 1, 17 to be joined. The clamps 2 are made of sheet steel and a tensioner 7 of classic construction is placed at their ends. A layer 200 of soft material is placed on the inside of the clamps 2, in order to prevent possible damage to the pipes 1.17 when the clamps are tightened around them. The clamps 2 are attached to the pipes 1.17 with tensioners 7, the construction of which is known. On the clamps 2, on each side, at an angle of 45° in relation to the tensioner 7, one hook 3 is attached. On the clamp 2, which includes the pipe 1, one locking mechanism 11 with a toothed bar 111 and a pusher 15 is attached to each hook 3. Each locking mechanism is coupled (in a known manner) with one handle 16. The locking mechanism 11 is connected to the clamp 2 by inserting the hook 3 of the clamp 2 into the groove 29 of the outlet 25 and securing it with a fuse 26. The end of the tension lever 19 is placed in the groove 151 of the pusher 15 and secured with a screw 10. The hook 191 is on the other end of the tension lever 19 is hooked to the hook 201 of the tension lever 20, the second hook 201 of which is hooked to the hook 3 on the clamp 2 that includes the end of the tube 17.

The method of operation of the device for connecting/separating pipes, according to the invention, is simple and follows in an obvious way from the previous description and drawings. The drawing (fig. 1) shows how the device is mounted when it is in function for connecting pipes 1.17. The locking mechanisms 11 are adjusted so that by gently pulling the levers 16, the gear rotates which axially moves the toothed rack 111, and its pusher 15 pulls the second clamp 2 through the tension levers 19, 20, attracting the pipe 17. In this way, an easy, simple and quick connection of the pipe 1, 17 is enabled.

When separating the pipes, the clamps 2 are positioned at the ends of the pipes in the same way as in the previous case. The tension levers 19, 20 are unhooked from the hook 3 and the pusher 15 which is against the end of the tube 17. The locking mechanism is now adjusted to rotate in the opposite direction from the previous case. By gently pulling the levers 16, the toothed racks 111 move axially in the opposite direction from the joining direction, push the pushers 15 to the end of the pipe 17, and their clamp 2 pulls the pipe 1 out of the pipe 17. In this way, easy, simple and quick separation of the pipes 1,17 is enabled.

Method of industrial or other application of the invention

No special knowledge, experience or instructions are required for the production, assembly and application of devices for joining/separating pipes.

The device for joining/separating pipes is effectively used for pipes with a diameter of 80-1000mm. It is particularly suitable for pipes made of brittle materials such as ceramics, PVC and fiberglass epoxy.

During production and assembly, it is necessary to pay attention to the following details:

- for higher clamp tightening forces, if necessary, lever 18 is used, which increases the lever on the tensioner 7 and enables easier tightening;

- lining 200 on the inside of clamps 2 is made of soft materials, for example soft rubber, felt or some other soft material, in order to better protect the pipe surface;

- during the pipe separation procedure, the clamp 2 on the pipe 17 is not necessary, but it is recommended to install it in order to strengthen the pipe 17 and prevent its deformation or possible damage.
