Hydraulic support limiting device for mining equipment

Abstract

The hydraulic support limiting device for the mining equipment comprises a control table, a limiting box is fixedly connected to the control table, a plurality of first sliding grooves and second sliding grooves are formed in the limiting box, and a plurality of control rods penetrating through the first sliding grooves are arranged on the control table. And a plurality of locking grooves are formed in the inner side of the limiting box and located on one side of the second sliding groove. The locking device has the advantages that by arranging the locking box, the spring and other structures, when the control rod needs to be adjusted and controlled, the pressing rod is pressed downwards, the pressing rod pushes the mounting block to extrude the spring, the mounting block drives the locking block to move downwards to be separated from the locking groove, and unlocking of the control rod is achieved. After the control rod is controlled, the pressing rod is loosened, the spring pushes the mounting block to move upwards, and the mounting block drives the locking block to enter the locking groove to lock the control rod. And independent locking operation is not needed after regulation and control are completed, use is more convenient, and the problem that work of the hydraulic support is affected due to the fact that locking is forgotten or locking is not conducted easily and conveniently is solved.

Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic supports, in particular to a hydraulic support limiting device for mining equipment. Background Art

[0002] In the mining work, hydraulic supports are used to support the mine tunnel to prevent the mine tunnel from collapsing. The hydraulic support console controls the hydraulic support's lifting, moving, pushing, balancing, front beam extension and other actions. Its working reliability and safety are very important.

[0003] An existing hydraulic support limiter for coal mines uses a handle to drive the turntable to rotate and lower its bolts, and then the bolts drive the plate to press down. The pressure applied to the plate is transmitted to the movable rod and drives the slider to move through the connecting block, so that the block is away from the joystick to release the restriction on the joystick, so that the joystick can be operated through the hydraulic control console to control the hydraulic support, so that the handle is locked when not in use to prevent accidental contact from affecting the operation of the hydraulic support. However, the locking assembly needs to be locked again after operating the handle. In actual operation, it is very likely that the lock will be forgotten or not locked for convenience, which may cause accidental contact and affect the operation of the hydraulic support. For this reason, a hydraulic support limiter for mining equipment is proposed for improvement. Utility Model Content
