Technical Field

[0001] The utility model relates to the technical field of hydraulic supports, in particular to a hydraulic support column oil rope fixing device. Background Art

[0002] A hydraulic support is a structure used to control the mine pressure at a coal mining face. It is generally necessary to install a hydraulic support during underground production to support the inner wall of the mine. To prevent wear of the galvanized layer on the surface of the columns, existing hydraulic supports are equipped with oil ropes on the columns. However, the oil ropes tend to rise and fall with the rise and fall of the columns during installation and use, necessitating the use of oil rope fixing devices. Existing oil rope fixing devices are typically simple clamp rings, and therefore cannot be used with hydraulic columns of different diameters, thereby reducing the scope of use and practicality of the oil rope fixing devices.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4The utility model provides a technical solution: a hydraulic support column oil rope fixing device, including a clamp 1, one end of the clamp 1 is fixedly connected to a connecting block 2, and a mounting groove 203 is provided inside the connecting block 2, and a limiting groove 202 is provided on the inner side wall of the mounting groove 203, and a screw 201 is threadedly connected to the inner surface of one side of the connecting block 2, and a positioning nut 3 is fixedly connected to the outer surface of the other side of the clamp 1, and the positioning nut 3 corresponds to the screw 201 inside the surface of one side of the connecting block 2, and multiple groups of mounting seats 401 are fixedly installed on the outer surface of the clamp 1, and a hook 4 is rotatably installed inside the multiple groups of mounting seats 401, and a limiting mechanism is provided on one side of the hook 4.

[0019] As a technical optimization solution of the present invention, the limiting groove 202 on the inner wall of the installation groove 203 is aligned with the positioning nut 3, and the height of the limiting groove 202 is greater than the height of the positioning nut 3, and the depth of the limiting groove 202 is the same as the thickness of the positioning nut 3. The other end of the clamp 1 can be limited by the positioning nut 3 and the limiting groove 202, and the connection stability between the other end of the clamp 1 and the connecting block 2 is improved.

[0020] As a technical optimization solution of the present invention, the limiting mechanism includes a limiting plate 5, and the outer surfaces of both ends of the limiting plate 5 are symmetrically fixedly connected with a clamping plate 501, and the clamping plate 501 is buckled on the side surface of the clamp 1. One side surface of the limiting plate 5 is fixedly connected with a movable plate 502, and the inside of the movable plate 502 is sleeved on the side surface of the hook 4 through a through hole 503. The movable plate 502 is slidingly connected to the hook 4. The clamping plate 501 and the movable plate 502 symmetrically fixedly connected on both side surfaces of the limiting plate 5 cooperate with the through hole 503 to limit the hook 4, so that the oil rope can be fixed more stably.

The spring 403 on the lower surface of the top plate 402 can limit the movable plate 502 and the limit plate 5, preventing the limit plate 5 from detaching from the clamp 1 during the up and down lifting of the column, thereby causing the hook 4 to rotate loose and causing unstable installation of the oil rope.

[0022] When the present invention is in use, first put the clamp 1 on the upper end of the column, then insert the other end of the clamp 1 into the interior of the installation groove 203, and at the same time align the positioning nut 3 with the limiting groove 202, then the positioning nut 3 will enter the interior of the limiting groove 202, at this time the staff pushes the other end of the clamp 1 to clamp the clamp 1 tightly on the side surface of the upper end of the column, and then rotates the screw 201 inside the connecting block 2, then the screw 201 will be threadedly connected with the positioning nut 3, thereby The clamp 1 is fixed to the upper end of the column, and then the oil rope is placed on the inner upper end of the clamp 1, and the oil rope is fixed by the hook 4 on the outer surface of the clamp 1. When the oil rope needs to be replaced, the staff lifts the limit plate 5 upward, and then rotates the hook 4 to remove the original oil rope, and then places the new oil rope on the inner side of the upper end of the clamp 1. At this time, lift the limit plate 5 to push the hook 4 to its original position, and then release the limit plate 5 and push the spring 403 to buckle the limit plate 5 on the upper end of the clamp 1 to fix the oil rope.
