[0015] Beneficial effects

[0016] This invention provides a hydraulic support for ultra-high mining heights that is easy to transport. Compared with the prior art, it has the following advantages:

[0017] Beneficial effects:

[0018] 1. This easily transportable, ultra-high hydraulic support for mining height is constructed by placing the connecting seat into the connecting groove and then rotating the rotating rod. The rotation of the rotating rod causes the connecting rod and the docking rod to move towards each other. The first and second limit seats limit the connecting seat, while the docking rod supports the connecting rod, thus enabling the connecting seat to be supported and locked. This facilitates the removal and replacement of the balance cylinder and the support column, thereby reducing the overall height and making it easier to transport the hydraulic support body.

[0019] 2. This easy-to-transport extra-large mining height hydraulic support, by rotating the locking handle, drives the locking screw to rotate. The locking screw, together with the locking nut, inserts the locking rod into the locking hole, locking the first limit seat, preventing accidental contact and loosening, and improving the stability of use.

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

[0028] Please see Figure 1-5 The present invention provides a technical solution: an ultra-high mining height hydraulic support that is easy to transport, including a hydraulic support body 1. The hydraulic support body 1 is provided with a balance cylinder 4 and a support column 3 inside. The support column 3 and the balance cylinder 4 are both provided with a connecting mechanism 2 between them and the hydraulic support body 1. The balance cylinder 4 and the support column 3 can be removed and replaced through the connecting mechanism 2, thereby reducing the overall height and facilitating the transportation of the hydraulic support body 1.

[0029] The connecting mechanism 2 includes two connecting seats 212 and two connecting shafts 202. Multiple connecting seats 212 are fixedly installed at both ends of the support column 3 and the balance cylinder 4. Both ends of the two connecting shafts 202 are rotatably connected to mounting seats 201. Multiple connecting shafts 202 are installed inside the hydraulic support body 1 via mounting seats 201, allowing for removal and replacement of the connecting shafts 202 for easy maintenance and disassembly. Each connecting shaft 202 has a connecting groove 203, and a first connecting screw 204 is rotatably connected inside the connecting groove 203. One end of the first connecting screw 204 is drive-connected to a connecting turntable 205. The transmission structure between the connecting turntable 205 and the first connecting screw 204 includes a driving bevel gear and a driven bevel gear. The driving bevel gear and... The end of the connecting turntable 205 is fixedly connected, and the driven bevel gear is fixedly connected to the end of the first connecting screw 204, so that the connecting turntable 205 can drive the first connecting screw 204 to rotate. A socket 206 is fixedly connected to the connecting turntable 205, and a rotating rod 207 is inserted into the socket 206. A movable seat 208 is threadedly connected to the first connecting screw 204. Multiple connecting rods 209 are fixedly connected to the end of the movable seat 208. The multiple connecting rods 209 are evenly arranged between the movable seat 208 and the first limiting seat 210. The ends of the multiple connecting rods 209 are fixedly connected to the first limiting seat 210. Both the movable seat 208 and the first limiting seat 210 are slidably connected to the inner wall of the connecting shaft 202. A connecting rod is fixedly connected to the end of the first limiting seat 210. 211. The connecting rod 211 matches the connecting seat 212. The end of the connecting rod 211 passes through the inner wall of the connecting shaft 202 and communicates with the outside, allowing the connecting rod 211 to pass through the connecting seat 212 for support. The end of the connecting rod 211 has a mating hole 222. The end of the first connecting screw 204 is fixedly connected to a drive gear 213. A driven gear 214 is provided on one side of the drive gear 213. The driven gear 214 meshes with the drive gear 213, so that when the drive gear 213 rotates, it can drive the driven gear 214 to rotate in the opposite direction. This allows the first connecting screw 204 and the second connecting screw 216 to rotate in opposite directions, so that the mating rod 220 and the connecting rod 211 can move towards each other or towards each other. The driven gear 214 moves in opposite directions. A rotating shaft 215 is fixedly connected to one side of the driven gear 214. A second connecting screw 216 is fixedly connected to the end of the rotating shaft 215. Both the rotating shaft 215 and the second connecting screw 216 are rotatably connected to the inner wall of the connecting shaft 202. A connecting nut is threaded onto the second connecting screw 216. A guide plate 217 is fixedly connected to the connecting nut. The guide plate 217 is threadedly connected to the second connecting screw 216 through the connecting nut, so that when the rotating shaft 215 rotates, it can drive the second connecting screw 216 to rotate. The rotation of the second connecting screw 216 drives the connecting nut to move. The movement of the connecting nut drives the guide plate 217 to move. A guide hole 221 is provided on the guide plate 217, and a guide rod 218 is provided inside the guide hole 221.The guide rod 218 is fixedly connected to the inner wall of the connecting shaft 202. The guide plate 217 is slidably connected to the guide rod 218 through the guide hole 221, so that the guide hole 221 and the guide rod 218 can limit and guide the movement of the guide plate 217, allowing the guide plate 217 to move along the guide rod 218 and improving the stability during the movement. A second limiting seat 219 is fixedly connected to the bottom end of the guide plate 217. A mating rod 220 is fixedly connected to one side surface of the second limiting seat 219. The end of the mating rod 220 passes through the connecting shaft 202 and communicates with the connecting groove 203. The mating rod 220 and the mating hole The mating of 222 allows the mating rod 220 to be inserted into the mating hole 222, thereby limiting the connection seat 212 using the first limiting seat 210 and the second limiting seat 219. Simultaneously, the mating rod 220 supports the connection rod 211, thus supporting and locking the connection seat 212. This can be achieved by placing the connection seat 212 into the connection groove 203 and then rotating the rotating rod 207. The rotation of the rotating rod 207 causes the socket 206 to rotate, which in turn causes the connecting turntable 205 to rotate. The rotation of the connecting turntable 205 then causes the first connecting screw 204 to rotate. 4. Rotation drives the movable seat 208 to move, which in turn drives the connecting rod 209 to move. The connecting rod 209 then drives the first limiting seat 210 to move, which in turn drives the connecting insert rod 211 to move. During this process, the first connecting screw 204 rotates, driving the drive gear 213 to rotate. The drive gear 213 then drives the driven gear 214 to rotate, which in turn drives the rotating shaft 215 to rotate. The rotating shaft 215 then drives the second connecting screw 216 to rotate in the opposite direction to the first connecting screw 204. The rotation of the second connecting screw 216 then drives the connecting nut to move, thus connecting... The movement of the nut causes the guide plate 217 to slide along the guide rod 218. The movement of the guide plate 217 causes the second limiting seat 219 to move, which in turn causes the docking rod 220 to move, inserting it into the docking hole 222. The first limiting seat 210 and the second limiting seat 219 limit the connection seat 212, while the docking rod 220 supports the connection rod 211, thus enabling the connection seat 212 to be supported and locked. This facilitates the removal and replacement of the balance cylinder 4 and the support column 3, reducing the overall height and facilitating the transportation of the hydraulic support body 1.

[0030] Please see Figure 3-4A locking mechanism 5 is provided between the first limiting seat 210 and the connecting shaft 202. The first limiting seat 210 has a locking hole. The locking mechanism 5 includes a locking nut 501, which is fixedly installed on the connecting shaft 202. A locking screw 502 is threaded inside the locking nut 501. A locking handle 503 is fixedly connected to one end of the locking screw 502, and a locking rod 504 is fixedly connected to the other end of the locking screw 502. The locking rod 504 matches the locking hole. By rotating the locking handle 503, the locking screw 502 is rotated. The locking screw 502, in conjunction with the locking nut 501, inserts the locking rod 504 into the locking hole, thereby locking the first limiting seat 210, preventing accidental loosening, and improving the stability of use.

[0031] During operation, the connecting seat 212 is placed into the connecting groove 203. Then, the rotating rod 207 is rotated. The rotation of the rotating rod 207 causes the socket 206 to rotate, which in turn causes the connecting turntable 205 to rotate. The rotation of the connecting turntable 205 causes the first connecting screw 204 to rotate, which in turn causes the moving seat 208 to move. The movement of the moving seat 208 causes the connecting rod 209 to move, which in turn causes the first limiting seat 210 to move. The movement of the first limiting seat 210 causes the connecting insertion rod 211 to move. During this process, the rotation of the first connecting screw 204 causes the driving gear 213 to rotate, which in turn causes the driven gear 214 to rotate, which in turn causes the rotating shaft 215 to rotate, which in turn causes the... The second connecting screw 216 rotates in the opposite direction to the first connecting screw 204. The rotation of the second connecting screw 216 causes the connecting nut to move. The movement of the connecting nut causes the guide plate 217 to slide along the guide rod 218. The movement of the guide plate 217 causes the second limiting seat 219 to move. The movement of the second limiting seat 219 causes the docking rod 220 to move, inserting the docking rod 220 into the docking hole 222. The first limiting seat 210 and the second limiting seat 219 limit the connecting seat 212. At the same time, the docking rod 220 supports the connecting rod 211, so that the connecting seat 212 can be supported and locked. This makes it easier to remove and replace the balance cylinder 4 and the support column 3, thereby reducing the overall height and facilitating the transportation of the hydraulic support body 1.
