Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: an operating handle locking device of a fully mechanized mining hydraulic support comprises an operating handle 1 and supporting plates 2 arranged on two sides of the operating handle 1, wherein two ends of each supporting plate 2 are respectively connected with a threaded rod 3 through screws, and a fixing device 4 capable of fixing the operating handle 1 is fixed between the two threaded rods 3;

when the staff need remove operating handle 1, the staff can promote fixing device 4, and fixing device 4 can rotate certain angle, makes fixing device 4 can not cause certain the blockking to operating handle 1, then alright with promoting operating handle 1, realizes promoting the full-mechanized mining hydraulic support.

The two fixing devices 4 are respectively positioned at two sides of the operating handle 1, each fixing device 4 comprises a fixing tooth 5 fixed at the outer side of each threaded rod 3, the outer side of each fixing tooth 5 is meshed and connected with a positioning tooth 6, a rotating shell 7 is fixed at the outer side of each positioning tooth 6, each rotating shell 7 is rotatably sleeved at the outer side of each threaded rod 3 through a bearing, a supporting shell 8 is fixed at the bottom of each rotating shell 7, supporting teeth 9 are fixed inside each supporting shell 8, moving teeth 10 are meshed and connected to the supporting teeth 9, moving rods 11 are fixed on the moving teeth 10, connecting rods 12 are fixed at one ends of the moving rods 11, which are positioned at the outer sides of the supporting shells 8, and connecting pieces 13 are connected between the two connecting rods 12;

when the device is used, the two connecting rods 12 are pulled, the two connecting rods 12 drive the two moving rods 11 to rotate, the two moving rods 11 drive the supporting shell 8 to rotate, the supporting shell 8 drives the rotating shell 7 to rotate, so that the two rotating shells 7 drive the positioning teeth 6 to rotate, when the two connecting rods 12 rotate to a proper position, the connecting rods 12 stop rotating, meanwhile, the fixed teeth 5 are meshed with the positioning teeth 6, the connecting rods 12 are positioned, then when the connecting rods 12 are pulled, the connecting rods 12 drive the moving rods 11 and the moving teeth 10 to move in the supporting shell 8, so that the length of the moving rods 11 can be prolonged, the connecting rods 12 move to a proper position, the moving teeth 10 are meshed with the supporting teeth 9, the connecting rods 12 and the rotating rods are fixed, and the connecting rods 12 are prevented from influencing the rotation of the operating handle 1;

if only one side of the operating handle 1 needs to be adjusted, the connecting piece 13 can be opened when the operating handle is used, the connection relationship between the two connecting rods 12 is released, and then one connecting rod 12 can be pulled, so that the other connecting rod 12 still supports the operating handle 1.

The connecting piece 13 comprises a clamping groove 14 and a placing groove 15 which are respectively arranged at one end of the two connecting rods 12, the clamping groove 14 is an L-shaped clamping groove 14, a compression spring 16 is fixed inside the placing groove 15, and a clamping block 17 clamped with the clamping groove 14 is fixed at one end of the compression spring 16;

when the connection relation between two connecting rods 12 needs to be removed, one side of the connecting rod 12 can be pulled, the connecting rod 12 can drive the clamping block 17 to move, the clamping block 17 is compressed by the edge of the clamping groove 14 in the moving process, the clamping block 17 and the compression spring 16 are compressed into the placing groove 15, and therefore the clamping relation between the two connecting rods 12 is removed

The top of the supporting shell 8 is fixed with a through groove 18, and the top of the moving rod 11 is fixed with a push rod 19 which is connected with the inner wall of the through groove 18 in a sliding way.
