Description

Technical Field

[0001] This utility model relates to the field of hydraulic support jack technology, specifically a tool for disassembling and assembling an external guide sleeve for a hydraulic support jack. Background Technology

[0002] Hydraulic support jacks are core components of the support system in underground fully mechanized mining faces. They are mainly used to drive hydraulic supports to complete lifting, moving, and other actions, ensuring the stability of the working space and the safety of personnel. Their external guide sleeves serve guiding, positioning, and protective sealing functions, and require regular disassembly and maintenance to prevent wear from affecting the jack's operational accuracy. The external guide sleeve disassembly and assembly tools are maintenance equipment specifically designed for this component. Their adaptability, labor-saving features, and operational stability directly determine the maintenance efficiency and quality of the hydraulic supports, making them important auxiliary tools for ensuring the normal operation of underground support equipment.

[0003] Existing hydraulic support jack external guide sleeve disassembly and assembly tools have many obvious defects. On the one hand, there is a lack of specialized designs for different jack specifications. When repairing small jacks, large column dismantling machines must be used, resulting in a waste of resources due to "using a large horse to pull a small cart." This not only occupies the time of large equipment, causing delays in the disassembly of large jacks and columns, but also consumes a lot of electricity, significantly increasing maintenance costs and resulting in extremely low maintenance efficiency. On the other hand, the force application structure of traditional tools is unreasonable, requiring a lot of manpower to operate. Moreover, the fit and tightness with the guide sleeve are insufficient, making it easy for slippage and uneven force to occur during the force application process. This not only affects the disassembly and assembly progress but may also damage the guide sleeve. In addition, the design of the tool's grip is poor, with insufficient comfort and anti-slip performance. Prolonged operation can easily lead to hand fatigue for workers, further reducing work efficiency. Utility Model Content

[0007] The gripping mechanism includes a gripping component, a locking component, a locking component, and a fixing component. The gripping component is disposed on the outer ring of the force-applying handle, the locking component is disposed on the inner side of the gripping component, the locking component is disposed on the outer ring of the gripping component, and the fixing component is disposed on the top of the locking component.

[0008] Preferably, the disassembly assembly includes a semi-circular retaining sleeve, which is fixedly connected to the left side of the force-applying handle, and a reinforcing fin is fixedly connected to the right side of the semi-circular retaining sleeve, which is fixedly connected to the top left side of the force-applying handle.

[0009] Preferably, the vertical width of the semi-circular sleeve gradually increases from left to right, and the vertical width of the force-applying handle gradually increases from right to left.

[0010] Preferably, the anti-slip component includes a locking strip and a locking protrusion, the locking strip being fixedly connected to the left side inside the semi-circular sleeve, and the locking protrusion being fixedly connected to the bottom right side inside the semi-circular sleeve.

[0011] Preferably, the grip assembly includes a grip sleeve, which is fitted onto the front and rear sides of the outer ring of the force-applying handle. The front and rear sides cause the inner side of the grip sleeve to fit together. The left and right sides of the outer ring of the grip sleeve are fixedly connected with protruding edges, and the outer ring of the grip sleeve is fixedly connected with anti-slip protrusions at the front and rear sides of the force-applying handle.

[0012] Preferably, the locking assembly includes a locking seat, which is fixedly connected to the inner side of the grip sleeve and engages with the front and rear sides of the force-applying handle.

[0015] Compared with the prior art, this utility model provides a tool for disassembling and assembling an external guide sleeve for a hydraulic support jack, which has the following advantages:

[0016] 1. This hydraulic support jack external guide sleeve disassembly and assembly tool is specially designed for small jacks and is compatible with their external guide sleeve specifications. It avoids the waste of resources caused by "using a large horse to pull a small cart" in traditional maintenance. It does not require the time of large column dismantling machine, so it does not delay the dismantling of large jacks and columns, and saves electricity consumption and maintenance costs, significantly improving maintenance efficiency.

[0017] Meanwhile, the extended design of the force-applying handle allows operators to complete the operation with less force by leveraging the principle of leverage, making it more labor-saving. The locking strip inside the semi-circular sleeve can be precisely locked into the protruding position of the outer ring of the guide sleeve. The tight fit between the locking protrusion and the guide sleeve not only enhances the transmission of force but also increases the friction between the two, effectively preventing slippage or uneven force during application. This ensures the progress of disassembly and assembly while preventing damage to the guide sleeve.

[0018] 2. This hydraulic support jack external guide sleeve assembly and disassembly tool, through its designed grip mechanism, features anti-slip protrusions on the outer ring of the grip sleeve that not only enhance grip stability but also optimize operating comfort. Even during extended work periods, it effectively reduces hand fatigue and maintains continuous work efficiency. Furthermore, the grip sleeve adopts a front-to-back splicing design, achieving quick locking via a locking sleeve and lever. Operators only need to rotate the bolt to lock or unlock the grip sleeve, making the assembly and disassembly process simple and convenient. It can quickly adapt to underground maintenance scenarios, further enhancing the overall ease and flexibility of operation. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] This utility model provides a technical solution:

[0030] Example 1

[0031] Combination Figures 1 to 3 A tool for disassembling and assembling an external guide sleeve for a hydraulic support jack includes a force-applying handle 3, a disassembly mechanism 1 fixedly connected to the left side of the force-applying handle 3, and a gripping mechanism 2 provided on the outer ring of the force-applying handle 3.

[0032] The disassembly mechanism 1 includes a disassembly component 11 and an anti-slip component 12. The disassembly component 11 is located on the left side of the force-applying handle 3, and the anti-slip component 12 is located inside the disassembly component 11.

[0033] The disassembly component 11 includes a semi-circular retainer 1101, which is fixedly connected to the left side of the force-applying handle 3. A reinforcing fin 1102 is fixedly connected to the right side of the semi-circular retainer 1101, which is fixedly connected to the top left side of the force-applying handle 3. The vertical width of the semi-circular retainer 1101 gradually increases from left to right, and the vertical width of the force-applying handle 3 gradually increases from right to left. The anti-slip component 12 includes a retaining strip 1201 and a retaining protrusion 1202. The retaining strip 1201 is fixedly connected to the left side inside the semi-circular retainer 1101, and the retaining protrusion 1202 is fixedly connected to the bottom right side inside the semi-circular retainer 1101.

[0034] Furthermore, the extended design of the force-applying handle 3 allows operators to achieve the desired operation with less force through leverage, saving effort. Simultaneously, the locking strip 1201 ensures that when the semi-circular sleeve 1101 is engaged with the outer ring of the guide sleeve, it can be engaged at the protruding position of the guide sleeve's outer ring. This increases the force transmission after the semi-circular sleeve 1101 and the guide sleeve are in contact, making it less likely for the semi-circular sleeve 1101 to detach from the guide sleeve. When the semi-circular sleeve 1101 applies torque to the guide sleeve while engaged with the outer ring, the locking protrusion 1202 engages with the guide sleeve, and together with the locking strip 1201, increases the friction between the semi-circular sleeve 1101 and the guide sleeve during use. This further improves the fit between the semi-circular sleeve 1101 and the guide sleeve during use, facilitating the operator's control of the guide sleeve's rotation and disassembly.

[0035] Example 2

[0036] See Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 Furthermore, based on Embodiment 1, the gripping mechanism 2 includes a gripping component 21, a locking component 22, a locking component 23, and a fixing component 24. The gripping component 21 is disposed on the outer ring of the force-applying handle 3, the locking component 22 is disposed on the inner side of the gripping component 21, the locking component 23 is disposed on the outer ring of the gripping component 21, and the fixing component 24 is disposed on the top of the locking component 23.

[0037] The grip assembly 21 includes a grip sleeve 2101, which is fitted onto the front and rear sides of the outer ring of the force-applying handle 3. The front and rear sides cause the inner sides of the grip sleeve 2101 to fit together. Protrusions 2102 are fixedly connected to the left and right sides of the outer ring of the grip sleeve 2101. Anti-slip protrusions 2103 are fixedly connected to the outer ring of the grip sleeve 2101 at the front and rear sides of the force-applying handle 3. The locking assembly 22 includes a locking seat 2201, which is fixedly connected to the inner side of the grip sleeve 2101 and engages with the front and rear sides of the force-applying handle 3. A locking block 2202 is fixedly connected to the inner side of the locking seat 2201 and engages with the front and rear sides of the force-applying handle 3. The locking assembly 23 includes a locking sleeve 2301, which is fitted onto the outer side of the grip sleeve 2101. On the left side of the ring, the left side of the locking sleeve 2301 fits against the right side of the left side protrusion 2102. The top of the locking sleeve 2301 is fitted with a plate 2302. The bottom of the plate 2302 is fixedly connected to a lever 2303. The lever 2303 passes downward through the locking sleeve 2301 and the grip sleeve 2101 and is fitted into the top of the force-applying handle 3. The fixing component 24 includes a fixing seat 2401. The fixing seat 2401 is fixedly connected to the top of the plate 2302. The top of the fixing seat 2401 is fixedly connected to a fixing screw 2402. The inner ring of the fixing screw 2402 is threaded with a bolt 2403. The outer ring of the bolt 2403 is fitted with a sleeve 2404. The sleeve 2404 is set on the left and right sides of the plate 2302 and is fixedly connected to the top of the locking sleeve 2301.

[0038] Furthermore: The grip sleeve 2101 is set on the outer ring of the force-applying handle 3. The anti-slip protrusion 2103 improves the comfort and stability of the staff when gripping the handle 3, so that when the staff grips the force-applying handle 3 to control the rotation of the semi-circular sleeve 1101, the palm can fit more closely with the entire force-applying handle 3, effectively preventing slippage.

[0039] Furthermore, the grip sleeve 2101 is designed with front and rear splicing. It is locked by the locking sleeve 2301 and the locking rod 2303 that are sleeved on the outer ring. The operator only needs to control the rotation of the bolt 2403 to lock or unlock the grip sleeve 2101 on both the front and rear sides, which makes it easy for the operator to disassemble and assemble the grip sleeve 2101. The operation is simple and convenient for the operator to use.

[0040] In actual operation, when this device is used, the operator first places the semi-circular sleeve 1101 on the outer ring of the guide sleeve, so that the inner ring of the semi-circular sleeve 1101 fits against the guide sleeve. Then, the operator holds the force-applying handle 3 and applies downward force. At this time, the semi-circular sleeve 1101 is locked into the guide sleeve by the locking strip 1201 and the locking protrusion 1202, so that the guide sleeve can rotate with the rotation of the semi-circular sleeve 1101. After the force-applying handle 3 rotates and moves downward a certain distance, the operator releases the direct contact between the semi-circular sleeve 1101 and the guide sleeve, then adjusts the angle of the semi-circular sleeve 1101 and locks it back into the outer ring of the guide sleeve. Then, the operator presses down the force-applying handle 3 again to control the rotation of the semi-circular sleeve 1101. The above operation is repeated continuously to make the guide sleeve rotate gradually and complete the disassembly.

[0041] When it is necessary to disassemble the grip sleeves 2101 on both the front and rear sides, the worker first rotates the bolt 2403. The bolt 2403 rotates to the right within the inner ring of the fixing screw 2402, and the bolt 2403 moves to the right to disengage from the fixing screw 2402 and the sleeve 2404. Then the worker can move the fixing screw 2402 upward. The upward movement of the fixing screw 2402 drives the locking rod 2303 upward. The upward movement of the locking rod 2303 disengages from the force-applying handle 3, the grip sleeve 2101 and the locking sleeve 2301. Subsequently, the worker can move the locking sleeve 2301 to the right to disassemble the locking sleeve 2301. After the locking sleeve 2301 is disassembled, the worker can move the grip sleeves 2101 on both the front and rear sides to disengage from the force-applying handle 3. At this point, the disassembly of the grip sleeve 2101 is completed.
