[0004] While the protective device between adjacent hydraulic supports in this mine can be bent to meet the needs of different working conditions, the height of the protective plate is not adjustable in practice, which cannot better adapt to different actual protection needs. Therefore, it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device and method for adjacent hydraulic supports in mining, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a protective device between adjacent hydraulic supports in a mine, comprising a base, an installation mechanism fixedly connected to the top of the base, and support mechanisms fixedly connected to both ends of the bottom of the base; The installation mechanism includes a lifting component and a plug-in component, wherein the plug-in component is disposed on one side of the lifting component; The support mechanism includes a T-shaped block, which is disposed at the left and right ends of the base and is fixedly connected to the top of the base. A third spring is fixedly connected to the left side of the T-shaped block, and a sliding rod is fixedly connected to the left end of the third spring. A sliding cylinder is slidably connected to the surface of the sliding rod, and a side plate is fixedly connected to the left end of the sliding cylinder. A locking post is fixedly connected to the right side of the side plate.

[0007] According to the above technical solution, the lifting assembly includes a support column, which is fixedly connected to the top of the base. A motor is fixedly connected to the top of the support column, and a lead screw is fixedly connected to the bottom of the motor. A threaded block is threaded onto the surface of the lead screw. A first spring is fixedly connected to the right end of the threaded block, and a convex plate is fixedly connected to the right end of the first spring. A positioning clip is fixedly connected to the middle of the right side of the convex plate. Support plates are fixedly connected to the front and rear sides of the threaded block, respectively. A limit strip is provided inside the threaded block, and an adjusting bolt is provided inside the support plate. The right end of the adjusting bolt is rotatably connected to the surface of the convex plate.

[0008] According to the above technical solution, a sliding groove is provided inside the support column, the surface of the threaded block is slidably connected to the inside of the sliding groove, and the bottom of the screw is rotatably connected to the bottom of the sliding groove. This facilitates the screw to rotate under the rotational support of the bottom end inside the sliding groove, and also facilitates the threaded block to move up and down in the support column, and facilitates the layer-by-layer installation of the protective plate.

[0009] According to the above technical solution, the threaded block has a through hole inside, the surface of the limiting strip passes through the through hole inside the threaded block, the surface of the support plate has a threaded hole, and the surface of the adjusting bolt is threadedly connected to the inside of the threaded hole.

[0010] According to the above technical solution, the plug-in assembly includes a U-shaped seat, which is fixedly connected to the middle of the top of the base. A protective plate is provided on the top of the U-shaped seat. A second spring is fixedly connected to the top front of the protective plate. A pull bar is fixedly connected to one end of the front of the second spring. A locking bar is fixedly connected to the back of the pull bar. A beveled locking bar is fixedly connected to one end of the back of the locking bar. A slide is provided on the back of the beveled locking bar. An insert is fixedly connected to the right end of the protective plate. An insert post is fixedly connected to the bottom end of the protective plate. A positioning hole is provided on the left side of the protective plate.

[0011] According to the above technical solution, the top of the protective plate has an insertion hole, the surface size of the insertion post is smaller than the internal size of the insertion hole, the top of the protective plate has a slot, the surface size of the slide is smaller than the internal size of the slot, the front of the slide has a latch, the top of the front of the protective plate has a through hole, and the surface of the locking bar passes through the through hole at the top of the front of the protective plate. When the insertion post is inserted into the insertion hole at the top of the protective plate, the inclined locking bar can be locked into the latch at the front of the slide by the support of the locking bar in the through hole at the top of the front of the protective plate, thereby installing the protective plate.

[0012] According to the above technical solution, a T-shaped groove is provided at the bottom of the base, and openings are provided at the bottom and front and rear sides of the T-shaped groove. The surface of the T-shaped block is slidably connected to the inside of the T-shaped groove.

[0013] According to the above technical solution, a slot is provided on the side of the base, the surface of the sliding cylinder and the surface of the sliding rod are located inside the slot, and a positioning hole is provided on the side of the base. The surface size of the locking post is smaller than the internal size of the positioning hole, so that the locking post can be inserted into the positioning hole on the side of the base to fix the T-shaped block when it moves, thereby increasing the support area at the bottom of the base and improving the overall support performance of the base.

[0014] Another technical problem to be solved by the present invention is to provide a method for protection between adjacent hydraulic supports in non-mining applications, so as to solve the problems mentioned in the background art above; To achieve the above objectives, the present invention provides the following technical solution, comprising the following steps: S1: Installation operation of the protective reinforcement Move the device to the vicinity of the coal mine where coal mining is to be carried out. Select a relatively flat and clean non-cement and non-concrete ground nearby, place the device there, and initially fix the base of the device to the ground. Then, install the protective plates one by one from the bottom layer until the bottom layer of protective plates is completely installed. S2: Increased height when installing the protective frame After the lowest layer of protective plates is installed, the current height of the protective plates is no longer sufficient to meet the actual needs of the coal mine. Therefore, the protective frame will be further heightened according to the actual situation. After the first layer of protective plates is installed, the first layer of protective plates is lifted using motors and other equipment. When the protective plates are moved to a suitable height, a new protective plate is installed at the bottom of the first layer of protective plates. After installation, the position of the protective plates is adjusted using motors and the protective plates are installed. At this time, the original bottom layer of protective plates will be moved to the next layer. S3: Support for the bottom of the protective frame Before adjusting the height of the protective plate, the support area at the bottom of the protective plate should be adjusted first. After the base of the protective plate is adjusted to a suitable support area, further support is needed at the bottom, and rivets are used to fix the base.

[0015] According to the above technical solution, when the height of the protective plate is increased, its support for the bottom of the protective frame also needs to be adjusted accordingly based on the height of the protective plate, and its support stability should be ensured.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: The protective device and method for adjacent hydraulic supports in this mine involves setting up an installation mechanism, in which a positioning clip is inserted into the positioning hole of the protective plate, and then the motor is started to drive the lead screw to rotate, thereby driving the threaded block to move upward and the protective plate to move upward. After moving to a suitable height position, the protective plate is heightened by installation at the bottom of the protective plate.

[0017] The protective device and method for adjacent hydraulic supports in this mine utilizes an installation mechanism. The bottom slide is inserted into a slot at the top of the bottom protective plate. The slide moves downward and presses against the side of the inclined locking strip inside the slot. This causes the inclined locking strip to move outward under the limiting support of the locking bar inside the through hole of the protective plate. Under the elastic action of the second spring, the inclined locking strip is driven into the slot inside the slide to perform the installation operation of the protective plate, which is convenient to better adapt to different actual protection needs.

[0018] The protective device and method for adjacent hydraulic supports in this mine utilizes a support mechanism. The locking pins at the top of the side plate disengage from the positioning holes on the side of the base. Then, the T-shaped blocks move to both sides of the base, increasing the support area at the bottom of the base and thus providing stability support for the base bottom.

[0019] The protective device and method for adjacent supports of the mine hydraulic support utilizes a support mechanism that uses a locking pin to engage with the positioning hole on the side of the base to fix the T-shaped block during movement, thereby increasing the support area at the bottom of the base and improving the overall support performance of the base.

A sliding groove is opened inside the support column 211. The surface of the threaded block 214 is slidably connected to the inside of the sliding groove. The bottom of the lead screw 213 is rotatably connected to the bottom of the sliding groove.

[0025] Furthermore, the threaded block 214 has a through hole inside, the surface of the limiting strip 218 passes through the through hole inside the threaded block 214, the support plate 217 has a threaded hole on its surface, the adjusting bolt 219 is threadedly connected to the inside of the threaded hole, and the positioning clip 2162 is inserted into the positioning hole in the protective plate 222. Then, the motor 212 is started to drive the lead screw 213 to rotate, thereby moving the threaded block 214 upward and the protective plate 222 upward. After moving to a suitable height position, an additional layer is added at the bottom of the protective plate 222. In the heightening installation operation of the protective plate 222, the bottom slide 227 is inserted into the slot opened at the top of the bottom protective plate 222. The slide 227 moves downward and presses against the side of the inclined retaining strip 226 inside the slot, thereby driving the inclined retaining strip 226 to move outward under the limiting support of the retaining bar 225 inside the through hole opened inside the protective plate 222. Under the elastic action of the second spring 223, the inclined retaining strip 226 is driven into the slot opened inside the slide 227, and the protective plate 222 is installed.

[0026] See Figure 1-7Furthermore, based on Embodiment 1, the insertion assembly 22 further includes a U-shaped base 221, which is fixedly connected to the top center of the base 1.

[0028] This invention provides a method for protecting adjacent hydraulic supports in non-mining applications to address another technical problem, comprising the following steps: S1: Installation operation of the protective reinforcement Move the device to the vicinity of the coal mine where coal mining is to be carried out. Select a relatively flat and clean non-cement and non-concrete ground nearby, place the device there, and initially fix the base of the device to the ground. Then, install the protective plates one by one from the bottom layer until the bottom layer of protective plates is completely installed. S2: Increased height when installing the protective frame After the lowest layer of protective plates is installed, the current height of the protective plates is no longer sufficient to meet the actual needs of the coal mine. Therefore, the protective frame will be further heightened according to the actual situation. After the first layer of protective plates is installed, the first layer of protective plates is lifted using motors and other equipment. When the protective plates are moved to a suitable height, a new protective plate is installed at the bottom of the first layer of protective plates. After installation, the position of the protective plates is adjusted using motors and the protective plates are installed. At this time, the original bottom layer of protective plates will be moved to the next layer. S3: Support for the bottom of the protective frame Before adjusting the height of the protective plate, the support area at the bottom of the protective plate should be adjusted first. After the base of the protective plate is adjusted to a suitable support area, further support is needed at the bottom, and rivets are used to fix the base.

[0029] When the height of the protective plate is increased, its support for the bottom of the protective frame also needs to be adjusted accordingly to ensure its stability.

[0030] In actual operation, when this device is used for protection, the top of the U-shaped base 221 has an open slot. First, the device is installed by inserting the protective plate 222 into the open slot at the top of the U-shaped base 221. Then, another protective plate 222 is installed by inserting its bottom slide 227 into the slot at the top of the bottom protective plate 222. During insertion, the slide 227 moves downwards and presses against the side of the inclined retaining strip 226 inside the slot, thereby driving... The inclined clip 226 moves outward under the limiting support of the clip 225 inside the through hole opened inside the protective plate 222, and elastically changes the second spring 223. Then, when the slot on the slide 227 is located on one side of the inclined clip 226, the inclined clip 226 is driven into the slot opened inside the slide 227 under the elastic action of the second spring 223. At the same time, the insert 229 is also inserted into the insertion hole opened at the top of the protective plate 222, thereby performing the splicing and installation operation of the protective plate 222. Additionally, when it is necessary to further increase the height of the protective plate 222, the motor 212 is started to drive the lead screw 213 to rotate, which in turn drives the threaded block 214 to slide up and down inside the groove opened in the support column 211, and drives the positioning clip 2162 to move into the positioning hole opened on the side of the protective plate 222. Then, the adjusting bolt 219 is rotated and, under the action of the threaded hole inside the support plate 217, the adjusting bolt 219 is moved, which in turn drives the convex plate 2161 to move, thereby driving the positioning clip 2162 to engage in the positioning hole opened in the protective plate 222. Then, the motor 212 is started to drive the lead screw 213 to rotate, which in turn drives the threaded block 214 to move upward, and drives the protective plate 222 to move upward. After moving to a suitable height position, the heightening installation operation of the protective plate 222 is carried out at the bottom of the protective plate 222. Furthermore, as the height of the protective plate 222 increases, its center of gravity also increases. Therefore, it is necessary to increase the support area at the bottom of the base 1. At this time, the side plate 35 is pulled outward, and the slide cylinder 34 moves under the limiting support of the slide rod 33. This causes the locking pin 36 at the top of the side plate 35 to disengage from the positioning hole opened on the side of the base 1. Then, the T-shaped block 31 is moved to both sides of the base 1 to increase the support area at the bottom of the base 1, thereby providing support for the stability of the bottom of the base 1.
