[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Embodiment 1, as Figures 1-4 shown, the present utility model provides a disassembly tool for the guide sleeve of an underground hydraulic prop, including a positioning mechanism 1, and a disassembly mechanism 2 is fixedly installed on the top of the positioning mechanism 1;

[0026] The disassembly mechanism 2 includes two mounting plates 201. Circular holes two 202 are formed in the outer surfaces of both mounting plates 201. Slide grooves three 203 are formed in one side of the outer walls of both mounting plates 201. Slide blocks three 204 are movably embedded in the inner surfaces of both slide grooves three 203. A first gear 205 is fixedly installed between the outer surfaces of both slide blocks three 204. A group of second electric telescopic rods 206 are fixedly installed in the inner surface of the first gear 205. A group of pressing plates 207 are fixedly installed at the telescopic ends of the group of second electric telescopic rods 206. A second motor 208 is fixedly installed on one side of the outer wall of one of the two mounting plates 201. A rotating shaft 209 is fixedly installed at the output end of the second motor 208. The outer surface of the rotating shaft 209 is movably inserted between the inner surfaces of the group of circular holes two 202. A second gear 210 is fixedly sleeved on the outer surface of the rotating shaft 209. The outer surface of the second gear 210 is meshed and connected with the inner surface of the first gear 205.

[0027] The effect achieved by the entire Example 1 is that after a group of second electric telescopic rods 206 are started, the guide sleeve will be clamped and fixed by a group of pressing plates 207. Subsequently, the second motor 208 will drive the second gear 210 to rotate together through the rotating shaft 209. The second gear 210 will drive the first gear 205 to rotate together, so that the fixed guide sleeve rotates on the surface of the hydraulic column. After the second motor 208 is started, the first electric telescopic rod 103 will drive the slide block one 104 and the bottom plate 101 to move together, and remove the guide sleeve from the surface of the hydraulic column. This tool does not require manual operation during disassembly, effectively reducing labor costs and greatly improving the efficiency of disassembling the guide sleeve.

[0028] Example 2, as Figures 2-4 shown, the positioning mechanism 1 includes a bottom plate 101. Two slide grooves one 102 are formed in the top of the bottom plate 101. A first electric telescopic rod 103 is fixedly installed on one side of the inner walls of both slide grooves one 102. Slide blocks one 104 are movably embedded in the inner surfaces of both slide grooves one 102. The telescopic ends of both first electric telescopic rods 103 are fixedly connected to the outer side of the outer wall of the slide block one 104. Two support frames 105 are fixedly installed on the top of the bottom plate 101. Two slide grooves two 106 are formed in the top of the bottom plate 101. Two groups of circular holes one 107 are formed in the outer surface of the bottom plate 101. Two first motors 108 are fixedly installed on one side of the outer wall of the bottom plate 101. Bidirectional threaded rods 109 are fixedly installed at the output ends of both first motors 108. The outer surfaces of the bidirectional threaded rods 109 are movably inserted between the inner surfaces of the two groups of circular holes one 107. A group of slide blocks two 110 are threadedly connected to the outer surfaces of both bidirectional threaded rods 109. The inner surfaces of both slide grooves two 106 are movably embedded with the outer surfaces of the group of slide blocks two 110. A group of clamping blocks 111 are fixedly installed on the tops of both groups of slide blocks two 110. A fixed connection is made between the tops of the two slide blocks one 104 and the bottoms of the two mounting plates 201.

[0029] The effect achieved by the entire Embodiment 2 is as follows: First, place the hydraulic column to be disassembled horizontally on the top of the support frame 105, and then start the first motor 108. The first motor 108 will drive the rotation of the bidirectional threaded rod 109, causing a set of second sliders 110 to slide inside the second chute 106. The set of second sliders 110 will approach each other inside the second chute 106, driving the contraction of a set of clamping blocks 111 at the top to fix the hydraulic column, preventing the hydraulic column from shifting due to external forces during the disassembly of the guide sleeve. This will not only affect the effect and speed of the guide sleeve disassembly, but may also hit surrounding equipment and workers in serious cases, causing accidents.

[0030] Working principle: When a worker needs to disassemble the guide sleeve, they only need to first place the hydraulic column to be repaired or replaced horizontally on the top of the support frame 105, and then start the device. At this time, the first motor 108 starts to drive the rotation of the bidirectional threaded rod 109 inside the first round hole 107. When the bidirectional threaded rod 109 rotates, it will drive a set of second sliders 110 fixedly installed on its outer surface to slide inside the second chute 106. When the set of second sliders 110 move, it will cause a set of clamping blocks 111 fixedly installed at the top to approach each other, fixing the hydraulic column to prevent the hydraulic column from moving under force during the disassembly of the guide sleeve. Subsequently, a set of second electric telescopic rods 206 are started to drive a set of pressing plates 207 to contract and contact the surface of the guide sleeve, clamping and fixing the guide sleeve. After the second motor 208 is started, it will drive the rotation shaft 209 to rotate in the second round hole 202. When the second round hole 202 rotates, it will cause the second gear 210 fixedly sleeved on its outer surface to rotate together. When the second gear 210 moves, it will cause the first gear 205 meshed with it to rotate together. When the first gear 205 rotates, it will drive a set of second electric telescopic rods 206 and pressing plates 207 on its inner surface to rotate together, driving the guide sleeve to rotate and fall off on the surface of the hydraulic column. When the guide sleeve rotates, the first electric telescopic rod 103 starts to contract, driving the first slider 104 connected to it to slide inside the first chute 102. When the first slider 104 slides, it will cause the two bottom plates 101 at the top to move together, facilitating the disassembly of the guide sleeve.

[0031] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
