Description

Technical Field

[0001] This utility model relates to the field of mining hydraulic support technology, and in particular to a base maintenance component for mining hydraulic supports. Background Technology

[0002] Hydraulic supports are structures used to control mine pressure in coal mining faces. The mine pressure acts on the hydraulic supports as an external load. In the mechanical system of interaction between the hydraulic supports and the surrounding rock of the mining face, if the resultant force of all supporting components of the hydraulic supports is exactly in line with the resultant force of the external load acting on the hydraulic supports from the roof, then the hydraulic supports are well adapted to the surrounding rock of the mining face. In mining hydraulic supports, bases are used. After long-term use, the screws and other structures on the base may loosen. At this time, maintenance tools, such as screwdrivers, are needed to tighten and reinforce the screws on the base for maintenance. This maintenance component is used for the maintenance of the base.

[0003] After prolonged use, the screws on the base of a mining hydraulic support are prone to loosening, which can lead to safety issues during operation. Conventional screwdrivers have a simple structure and can only tighten individual screws during maintenance. However, some screws may experience stress between components due to the mechanical structure of the base after long-term support. In such cases, it is necessary to tap the components on the base to release the stress before tightening the screws. Ordinary screwdrivers cannot achieve this effect. Utility Model Content

A bottom sleeve is installed at the lower end of the grip rod, and a threaded rod is fixed to the bottom wall of the grip rod. The grip rod and the bottom sleeve are connected by the threaded rod. A sponge strip is installed at the center of the grip rod and the threaded rod, passing through the threaded rod and extending into the cavity. A disc-shaped top seat is installed on the grip rod, and a threaded connector connected to the grip rod is installed on the bottom wall of the top seat. The front wall of the top seat has a small threaded opening and a large threaded opening opposite each other. A large threaded head is installed on the center wall of the left end of the top seat, and a small threaded head is installed on the center wall of the rear end of the top seat.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution for a base maintenance component for a mining hydraulic support:

[0023] like Figure 1-4 As shown, a maintenance component for a base of a mining hydraulic support includes a handle 1. The handle 1 has a rod cavity 2 for storing lubricating fluid. A bottom sleeve 5 is installed at the lower end of the handle 1. A threaded rod 3 is fixed to the bottom wall of the handle 1. The handle 1 and the bottom sleeve 5 are connected by the threaded rod 3. The bottom sleeve 5 is hollow inside. The handle 1 and the threaded rod 3 are both bonded to a sponge strip 4. The sponge strip 4 is used to absorb the lubricating fluid added to the rod cavity 2. At the same time, the threaded rod 3 and the hollow cavity of the bottom sleeve 5 are threaded together. The bottom sleeve 5 is cylindrical and is used to rotate the bottom sleeve 5. The bottom sleeve 5 and the threaded rod 3 are disassembled and assembled. When assembling, the bottom sleeve 5 is fitted over the outside of the threaded rod 3, so that the sponge strip 4 is also fitted. Conversely, when the bottom sleeve 5 is removed, the sponge strip 4 is exposed. At this time, the sponge strip 4 that has absorbed the lubricating fluid can be applied to the end wall of the parts of the mining hydraulic support base for lubrication and maintenance.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a sponge strip 4 is installed at the center of the grip rod 1 and the screw 3. The sponge strip 4 passes through the screw 3 and the grip rod 1 and extends into the rod cavity 2. A disc-shaped top seat 6 is installed on the grip rod 1. The top seat 6 and the screw connector 7 are fixedly connected to each other. The top seat 6 is threadedly connected to the grip rod 1 through the screw connector 7 and the rod cavity 2. The rod cavity 2 is used to add lubricant. Then, the screw connector 7 is screwed into the rod cavity 2, and the top seat 6 is used to seal the grip rod 1.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, a screw connector 7 connected to the handle 1 is installed on the bottom wall of the top seat 6. A small screw 8 and a large screw 9 are opened opposite each other on the front wall of the top seat 6. A large screw head 10 is installed on the center wall of the left end of the top seat 6, and a small screw head 11 is installed on the center wall of the rear end of the top seat 6. The size of the small screw 8 is smaller than that of the large screw 9. At the same time, the axes of the small screw 8 and the large screw 9 are perpendicular to the top seat 6. The large screw head 10 and the small screw head 11 are fixedly connected to the top seat 6, and the large screw head 10 and the small screw head 11 are perpendicular to the axis of the top seat 6. When in use, hold the handle 1 and tap the right end wall of the top seat 6 to relieve stress. Then connect the small screw 8, the large screw 9, the large screw head 10 or the small screw head 11 on the top seat 6 to the screw or bolt of the base component. Then turn the handle 1 to tighten the screw connection to strengthen it, improve the stability of the base, and thus maintain the base.

[0026] Working principle:

[0027] First, rotate the top seat 6 to remove the grip rod 1. At this time, the rod cavity 2 of the grip rod 1 is opened. Add lubricant to the rod cavity 2, then screw the screw connector 7 into the rod cavity 2 to assemble the grip rod 1 and the top seat 6, and seal the rod cavity 2.

[0028] When in use, the bottom sleeve 5 can be rotated off first to expose the sponge strip 4. The sponge strip 4 is made of sponge, with one end extending into the rod cavity 2 to absorb the lubricant added to the rod cavity 2, so that the other end of the sponge strip 4 also has lubricant. At this time, hold the handle 1 and operate the sponge strip 4 to apply the lubricant to the mining hydraulic support base parts, and lubricate and maintain the end wall of the base. After use, the bottom sleeve 5 is put on the sponge strip 4 and screwed on to assemble it at the bottom of the handle 1, which can simply seal the sponge strip 4 for easy storage and use.

[0029] The top seat 6 is disc-shaped, with its right end face used to tap the base components to relieve stress. The small screw head 8 and the large screw head 9 are preferably hexagonal prism slots, but can also be octagonal prism slots. They are mainly used to fit the screw seats, bolt nuts, or screw seats on the base. In use, one of the small screw head 8 or the large screw head 9 is fitted onto the end wall of the screw seat, and then the handle 1 is turned to tighten it. The large screw head 10 and the small screw head 11 are preferably flat-headed, but can also be Phillips headed. They are mainly used to fit the screw seat slots and bolt seat slots on the base. Then, the handle 1 is held to tighten the screws or bolts, thereby maintaining the base.
