Description
Technical Field
The utility model belongs to mechanical equipment protection field, concretely relates to hydraulic support operating valve safety arrangement.
Background
At present, 84% of all-round production mines are widely applied to the comprehensive mechanized coal mining technology, the mechanized degree of the mines is continuously increased due to the application of the comprehensive mechanized coal mining technology, and the coal yield of the mines is greatly improved. During the maintenance of the working face, the operating valve handle in the middle of the hydraulic support of the mine coal face is frequently accidentally knocked by unconscious mistake by maintenance workers who come from or go back to the working face due to the fact that the number of the supports is large and no special person attends to the real-time state of the supports, and the moving position area of the operating valve handle of the hydraulic support of the coal face is not fixed, so that hydraulic leakage of a top beam of the support is caused after collision, the supporting position deviates and sinks, the top plate leaks and collapses a scraper conveyor, the damage of electromechanical equipment is easily caused, even personal casualty accidents are caused, and the safety production of the mine is severely restricted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a hydraulic support operating valve safety arrangement can solve and lead to the problem that electromechanical device damaged because of the hydraulic pressure operating valve handle malfunction.
The utility model discloses the technical scheme who adopts is, a hydraulic support operating valve safety arrangement, including two mounts of rigid coupling at hydraulic pressure operating valve both ends, two mounts are parallel to each other and the height-identical, and hydraulic pressure operating valve's bottom is equipped with a plurality of operating valve handle, and the operating valve handle sets up between two mounts, and one side bottom of every mount all is equipped with a pair of locating hole, and the height-identical of two pairs of locating holes runs through the locking lever between two sets of locating holes.
The utility model is also characterized in that,
the locking rod is a U-shaped rod.
The outer side of one of the fixed frames is provided with a placing hook which can hang the locking rod.
The length of the locking rod is larger than the distance between the two fixing frames.
When the locking rod is inserted into the positioning hole, one end of the locking rod is fixedly connected with the fixing frame through a screw.
The width of the locking rod is 1-3 cm larger than the diameter of the handle of the operating valve.
The utility model has the advantages that: during the maintenance and overhaul of the working face, the number of the supports is large, and the supports are not in a real-time state of being cared by a specially-assigned person, so that the supports are frequently collided by caregivers who come from or go back to the working face unconsciously by mistake, and the moving position area of the hydraulic support operating valve handle of the coal face is not fixed, so that misoperation is easily caused, and equipment damage or personnel injury is caused. The utility model provides an operating handle by fixed front and back small displacement, can not lead the hydrovalve action. The width between the U-shaped locking rods is slightly larger than the diameter of the operating handle, and the gap is within a safety range, so that the displacement of the operating handle is fixed after the locking device is inserted during maintenance, and the purpose of safety protection is realized.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 and 2, do the utility model relates to a hydraulic support operating valve safety arrangement's front view and side view, including two mounts 2 of rigid coupling at hydraulic operating valve 1 both ends, two mounts 2 are parallel to each other and highly the same, the bottom of hydraulic operating valve 1 is equipped with a plurality of operating valve handle 3, operating valve handle 3 sets up between two mounts 2, one side bottom of every mount 2 all is equipped with a pair of locating hole 5, the highly the same of two pairs of locating holes 5, run through locking lever 4 between two pairs of locating holes 5, locking lever 4 is the U-shaped pole.
As shown in fig. 3 and 4, a front view and a side view of the locking rod of the present invention hanging on the placing hook are provided, wherein a placing hook 6 capable of hanging the locking rod 4 is provided on the outer side of one of the fixing frames 2. The length of the locking rod 4 is larger than the distance between the two fixing frames 2, and when the locking rod 4 needs to be inserted into the positioning hole 5, one end of the locking rod 4 is fixedly connected with the fixing frames 2 through screws.
The width of the locking rod 4 is 1-3 cm larger than the diameter of the operating valve handle 3.
The utility model relates to a hydraulic pressure operating valve safety protection blocking device mainly includes mount 2 and 4 two parts of U type locking lever. The fixing frame 2 is fixed at two ends of the hydraulic operating valve 1, and the U-shaped locking rod 4 passes through the opened positioning hole 5 to reach the other end of the operating valve 1 during equipment maintenance, so that the movement of the operating valve handle 3 can be limited, and misoperation can be prevented. When the equipment is converted into a normal operation state, the U-shaped locking rod 4 is pulled out and inserted into the placing hole 6 on the side wall of any fixing frame 2, and the operation of the hydraulic valve is not influenced.
