The utility model provides a hydraulic support valves operation handle stop device, refer to fig. 1 to 2, the following elaboration.

A stop device for an operating handle of a hydraulic support valve group comprises a valve group body 1, wherein a plurality of operating handles 2 and a plurality of limiting rods 3 are arranged on the valve group body 1 in a row, two limiting rods 3 are arranged in the embodiment, the limiting rods 3 are parallel to the row arrangement direction of the operating handles 2, and a limiting mechanism 4 for controlling the limiting rods 3 to move is arranged on the valve group body 1; and the gag lever post 3 sets up to n shape, and gag lever post 3 is including the spacing section that is used for restricting operating handle 2 to and be used for connecting the linkage segment of stop gear 4, and the linkage segment sets up with stop gear 4 is articulated. Limiting mechanism 4 includes drive division 41 and pedal locking portion 42, pedal locking portion 42 and drive division 41 swing joint, and pedal locking portion 42 is used for controlling the spacing state of gag lever post 3, and the limiting mechanism 4 outside is provided with protective housing 6, and protective housing 6 can dismantle fixed connection with the valves organism, is provided with the movable bar groove that supplies pedal locking portion 42 and gag lever post 3 to remove on the protective housing 6. Through setting up pedal locking portion 42, the staff can control gag lever post 3 through controlling pedal locking portion 42 and remove to realize gag lever post 3 and reach and keep the spacing position to operating handle 2, reach the spacing purpose of operating handle 2 to the hydraulic support valves.

Referring to fig. 2, the transmission portion 41 includes a moving groove 411 disposed on the side wall of the valve body, a downward moving hole 412 is disposed in the middle of the moving groove 411, a return spring 413 is symmetrically disposed in the moving groove 411 with respect to the downward moving hole 412, two ends of the return spring 413 are connected with moving blocks 414, one side of the moving block 414 away from the valve body 1 is rotatably connected with a guide block 417, the guide block 417 is matched with the limiting rod 3 to be provided with a guide hole 418, and the limiting rod 3 is disposed in the guide hole 418 in a penetrating manner. The movable block 414 moves down the hole 412 position fixedly connected with flexible chain 415 towards, and the flexible chain 415 free end passes and moves down the hole 412 and be connected with the elevator, the elevator articulates the setting with the linkage segment of gag lever post 3, it is provided with the removal track along vertical movement slot 411 position to correspond the elevator position on the valves organism lateral wall, the cooperation removal track is provided with the slider on the elevator, and all be provided with the limiting plate at removal track's bottommost end and topmost, prevent that the elevator from breaking away from the removal track, elevator and pedal locking portion 42 swing joint. The pulley 5 for bearing the flexible chain 415 is arranged at the position of the downward moving hole 412, so that the situation that the flexible chain 415 is easy to break due to long-time friction with edges and corners is avoided, and the flexible chain 415 is a rope, so that the cost is reduced and the replacement is easy.

When the limiting locking is needed, a worker can drive the lifting block to descend through the pedal locking portion 42, the lifting block can drive the flexible chain 415 to descend when descending, the other end of the flexible chain 415 drives the moving block 414 to move towards the central position of the moving groove 411 in the moving groove 411, after the lifting block descends to the lowest position, the moving block 414 compresses the reset spring 413 to move to the position closest to a descending hole, the guide block 417 can drive the limiting rod 3 to ascend upwards along with the moving block 414 in the moving process, and the guide block 417 rotates during the ascending process of the limiting rod 3, so that the moving track of the guide block 417 can be matched with the moving track of the limiting rod 3. The arrangement of the pulley 5 prevents the rope from being broken due to friction with the edge of the drop hole during the movement of the rope.

Referring to fig. 2, the foot lock part 42 includes a foot board 421, a connecting rod 422 is disposed between the foot board 421 and the lifting block, the connecting rod 422 is hinged to the lifting block, the connecting rod 422 is fixedly connected to the foot board 421, a locking hook 423 is disposed on the foot board 421, and a positioning buckle 424 is disposed on the valve unit body 1 in cooperation with the locking hook 423; when the positioning buckle 424 is engaged with the locking hook 423, the stopper rod 3 is in a position-restricting state attached to the operation handle 2.

The setting of connecting rod 422 can be so that rotate between running-board 421 and the elevator, after the elevator reduced to the bottommost position, the staff can push away running-board 421 with the foot and make the location detain 424 and the loose foot behind the locking of locking hook 423, locking hook 423 and the locking of location knot 424 guarantee that the elevator can not rise this moment, and then guarantee that gag lever post 3 can keep pasting tight operating handle 2 both sides position to it is spacing to accomplish.

The working principle of the embodiment is as follows: when the staff carries out the valve body spacing, the staff steps on pedal 421 with the foot, pedal 421 drives the elevator through connecting rod 422 and descends, the elevator that descends can drive flexible chain 415 decline, flexible chain 415 drives movable block 414 and removes towards compression reset spring 413 direction, guide block 417 removes along with movable block 414 this moment, drive gag lever post 3 and upwards lift, thereby make gag lever post 3 reach and press close to operating handle 2 position, after the elevator reduces to the bottommost position, the staff can push away pedal 421 with the foot and make location knot 424 and locking hook 423 lock after the pine foot, locking hook 423 and location knot 424 lock this moment guarantee that the elevator can not rise, and then guarantee that gag lever post 3 can keep in the operation of clinging 2 both sides positions of operating handle, thereby accomplish spacingly. When the unlocking is needed, the foot pedal 421 is stepped on by foot to separate the positioning buckle 424 and the locking hook 423 from the locking state, and then the foot pedal 421 is pushed by foot to make the locking hook 423 completely separate from the positioning buckle 424 to complete the unlocking, and at this time, the limit rod 3 can be lowered to a position where the movement of the operating handle 2 is not affected.
