Specific embodiment
The present invention is further described With reference to embodiment, specific embodiment be to the principle of the invention into
One step explanation, does not limit the invention in any way, and same or like technology is protected without departing from the present invention with the present invention
Range.
In conjunction with attached drawing.
As shown, open and close system of the present invention is adapted to the hopper wagon of two sides shutter door, side door 8 is located under hopper wagon side wall
Portion is simultaneously hinged with the fixed side wall 7 in top, and hopper wagon side door 8 is along the longitudinally asymmetric setting at least two groups of hopper wagon, along hopper wagon longitudinal direction
A set of side door switching mechanism 1 is arranged in opposite one group of side door 8.
Switching mechanism 1 includes worm gearing and crank link mechanism；Worm gearing includes: rotation handwheel 1.1,
Conversion gear group 1.2, drive rod 1.3, the bevel gear set 1.5,1.4 and of worm gear composition that rotation handwheel 1.1 drives and is successively driven
Worm gear shaft 1.6, worm gear shaft 1.6 are arranged on hopper wagon car body by the positioning of bracket 1.8；Crank link mechanism is that have movement dead
Two crank link mechanisms, the end of the linking arm 1.7 1 of crank link mechanism and 8 lower end of side door is hinged, another end
Portion and the perpendicular drive of worm gear shaft 1.6 connect.
The switching mechanism 1 of every set side door 8 is provided with second level stop device 3, and the second level stop device 3 includes: and is driven
The co-axially fixed rotation stop ratchet 3.2 of bar 1.3, rotation stop ratchet 3.2 form the helical teeth on 3.4 with lever by ratchet and match realization system
Dynamic, lever composition 3.4 is hingedly fixed in 3.6 lower section of frame pedal by lever bracket 3.3, and lever forms 3.4 one end and setting
The connection of foot-driven lever 3.1 on 3.6 surface of frame pedal, the other end are provided with the spring 3.5 for lever return.
The drive rod 1.3 of worm gearing forms 1.4 Hes by the worm gear that bevel gear set 1.5 drives both ends to be set side by side
Worm gear shaft 1.6 simultaneously drives symmetrically arranged one group of opposite side door 8 to be opened and closed.
At least setting three set crank link structures in interval drive side door 8 on each worm gear shaft 1.6.
With side door lower end is hinged first connect arm lengths and be greater than and connect brachium with the second of worm gear shaft perpendicular drive connection
Degree, and the first linking arm is arcuate structure, in side when closed state, the first linking arm and side door lower end hinge position, the second company
Connect 3 points of the hinge position of the connection position of arm and worm gear shaft, the first linking arm and the second linking arm in a straight line.The structure is maximum
The torque for reducing to limit 1.6 Forced rotation of worm gear shaft cooperates the safety for further strengthening switching mechanism 1 with stop device 3
Locking performance.
As shown in Figure 3, Figure 4, the straight bevel gear that conversion gear group 1.2 and bevel gear set 1.5 are 1 using transmission ratio is complete
At the conversion in direction, handwheel 1.1 will be rotated by first order conversion gear group 1.2 and be converted to around axle power square around vertical direction transmission
The torque that bar 1.3 rotates, then will be converted into around vertical direction rotating torque by the realization of second level bevel gear set 1.5 and be turned around lateral
Dynamic torque, and rotated by 1.4 transmission driving worm gear shaft 1.6 of worm gear composition.
As shown in figure 4, the worm screw group that bevel gear set 1.5 drives is rotated using left-handed and dextrorotation setting driving worm gear shaft 1.6,
The transmitting of power is realized by biggish transmission ratio, rapid operation, due to the characteristic of worm gear composition 1.4, open and close system was opened
Will not there are the trend being automatically closed, safe operation in journey because rotation handwheel 1.1 is unclamped.
As shown in figure 5, the stop foot-driven lever 3.1 of stop device 3 is located on frame pedal 3.6, before operation rotation handwheel 1.1
The helical teeth that trampling foot-driven lever 3.1 makes lever form 3.4 one end leaves the ratchet of rotation stop ratchet 3.2, and rotating handwheel 1.1 at this time can be with
Transmission；Foot-driven lever 3.1 is unclamped, lever composition 3.4 returns to original place by the effect of spring 3.5, and rotation stop ratchet 3.2 is locked, and is turned
Wheel of starting 3.1 can not rotate；When spring 3.5 fails, since lever composition 3.4 is left light right heavy, returned by self gravitation effect
To original place, keep rotation stop ratchet 3.2 locked；Frame pedal 3.6 is fixed on hopper wagon car body by pedal bracket 3.7, rotation stop spine
Wheel 3.2 is placed in 3.6 lower section of frame pedal, 1.5 top of bevel gear set with the coaxial fixed bit of drive rod 1.3, is not shown in figure.
As shown in Figure 1 and Figure 2, this example hopper wagon side door 8 is along longitudinally asymmetric two groups of the setting of car body, every group of symmetrically arranged side
The independent switching mechanism 1 of 8 setting of door and stop device 3.
