[0002] According to the published patent CN203978443U, a support device for goaf retention includes a pre-splitting line for goaf retention. Pre-splitting blast holes are constructed on the pre-splitting line. A hydraulic prop and a hinged roof beam are used to erect a support structure along the direction of the pre-splitting blast holes. Anchor bolts and a metal mesh are used for support on the roof. This support device is simple to operate, inexpensive, simplifies the maintenance work at the working face end, reduces the labor intensity of workers, and can achieve significant social benefits. However, it still has the following shortcomings:
[0003] While the aforementioned equipment can provide support for gob-side roadway retention, it is inconvenient to adjust the length of the device during the support process. When it is necessary to support gob-side roadways of different widths, different models of devices need to be replaced, which is quite inconvenient. Therefore, we propose a gob-side roadway retention and support device. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a roadway forming and support device along the goaf, including a connecting plate, a plurality of top plates are slidably connected to the outer wall of the connecting plate, and the connecting plate is provided with an extension mechanism;
[0007] The extension mechanism includes a rotating shaft, an annular limiting block fixedly connected to the outer wall of the rotating shaft, several gears fixedly connected to the outer wall of the rotating shaft away from the annular limiting block, several electric telescopic rods fixedly connected to the inner wall of the connecting plate near the gears, racks fixedly connected to the bottom output ends of the electric telescopic rods near the gears, several limiting shafts rotatably connected to the inner wall of the annular limiting block, connecting rods fixedly connected to the outer walls of the limiting shafts, second limiting shafts fixedly connected to the inner wall of the connecting rod away from the limiting shafts, and clamping plates rotatably connected to the outer walls of the second limiting shafts. Several slots are provided on the inner wall of the top plate near the clamping plate, several sliding plates are fixedly connected to the inner wall of the connecting plate, several second sliding plates are fixedly connected to the inner wall of the connecting plate near the electric telescopic rods, and an adjustment mechanism is provided on the outer wall of the top plate.

[0009] Furthermore, the adjustment mechanism includes several support legs, and the outer walls of the several support legs are slidably connected to the bottom outer wall of the top plate.
[0010] Furthermore, a self-locking motor is fixedly connected to the outer wall of each of the supporting legs, and a worm gear is fixedly connected to the bottom output end of each of the self-locking motors via a coupling. The outer wall of the worm gear is rotatably connected to the inner wall of the supporting leg.
[0011] Furthermore, a rotating rod sleeve is rotatably connected to the inner wall of several of the support legs, and a worm wheel is fixedly connected to the outer wall of the rotating rod sleeve near the worm, and the outer wall of the worm wheel meshes with the outer wall of the worm.
[0012] Furthermore, the inner wall of the rotating rod sleeve is provided with several arc-shaped grooves, and the inner walls of several rotating rod sleeves are rotatably connected to top rods, the top outer wall of the top rods being fixedly connected to the bottom outer wall of the top plate.
[0013] Furthermore, a number of sliding rods are fixedly connected to the outer wall of one end of the top rod near the arc-shaped groove, and the outer wall of the sliding rods is slidably connected to the inner wall of the arc-shaped groove.

[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model, by setting a limiting shaft on the annular limiting block, allows for the simultaneous activation of an electric telescopic rod to shorten to a suitable length when the width of the goaf retention roadway varies, via the controller. The shortening of the electric telescopic rod drives a gear through a rack, which in turn drives a rotating shaft, causing the annular limiting block to rotate. This rotation of the annular limiting block, in turn, pulls a connecting rod via the limiting shaft, enabling the user to flexibly adjust the length of the device's support frame based on actual measured width data within the goaf retention roadway. This allows for quick matching of different roadway widths, effectively preventing support failure due to size discrepancies and ensuring the accuracy and stability of the roadway support. Furthermore, the device can be disassembled and assembled, improving user efficiency.
[0017] 2. This utility model incorporates an arc-shaped groove within the rotating rod sleeve. During equipment use, if the height of the top plate needs adjustment to suit different goaf-side roadway heights, multiple self-locking motors are simultaneously activated via the controller. The rotation of these motors drives the worm gear, which in turn rotates the worm wheel. This rotation of the worm wheel, in turn, drives the rotating rod sleeve. The rotating rod sleeve, through the arc-shaped groove, gradually rotates the sliding rod on the top rod. This allows users to easily adjust the device height according to the height requirements of different goaf-side roadway areas. Whether in low or high roadway sections, it provides stable support for the corresponding height support structure, adapting to diverse roadway environments and improving the efficiency and safety of support operations.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-7 As shown, this utility model is a roadway forming and support device along the goaf, including a connecting plate 1. Several top plates 101 are slidably connected to the outer wall of the connecting plate 1. The connecting plate 1 is provided with an extension mechanism 2. Through the connecting plate 1, multiple top plates 101 can be connected. At the same time, by adjusting the position of the top plates 101 fixed on the connecting plate 1, the length of the device support can be adjusted.
[0031] The extension mechanism 2 includes a rotating shaft 201. An annular limiting block 202 is fixedly connected to the outer wall of the rotating shaft 201. Several gears 203 are fixedly connected to the outer wall of the end of the rotating shaft 201 away from the annular limiting block 202. Several electric telescopic rods 204 are fixedly connected to the inner wall of the end of the connecting plate 1 near the gears 203. The rotating shaft 201 can limit the position of the annular limiting block 202 to prevent it from falling off. Simultaneously, when the rotating shaft 201 rotates, it can drive the annular limiting block 202 to rotate. A rack 205 is fixedly connected to the bottom output end of each of the electric telescopic rods 204 near the gears 203. Several limiting shafts 206 are rotatably connected to the inner wall of the annular limiting block 202. Connecting rods 207 are fixedly connected to the outer walls of each of the limiting shafts 206. The limiting shafts 206 can limit the position of the connecting rods 207 to prevent them from falling off. Simultaneously, when the limiting shafts 206 move... The connecting rod 207 is pulled to move. The inner wall of the end of the connecting rod 207 away from the limiting shaft 206 is fixedly connected to the second limiting shaft 208. The outer walls of several second limiting shafts 208 are rotatably connected to the locking plates 209. The inner wall of the top plate 101 near the locking plates 209 is provided with several slots 210. The inner wall of the connecting plate 1 is fixedly connected with several sliding plates 211. The sliding plates 211 can limit the movement trajectory of the locking plates 209, so that they can only slide in a straight line along the direction of the locking plates 209 on the sliding plates 211. The inner wall of the connecting plate 1 near the electric telescopic rod 204 is fixedly connected with several second sliding plates 212. The outer wall of the top plate 101 is provided with an adjustment mechanism 3. The second sliding plates 212 can limit the movement trajectory of the rack 205, so that it can only move in a straight line along the direction of the second sliding plates 212 on the second sliding plates 212. At the same time, it can prevent the rack 205 from disengaging from the gear 203.
[0032] The outer wall of the rotating shaft 201 is rotatably connected to the central axis of the inner wall of the connecting plate 1. The outer wall of the rack 205 meshes with the outer wall of the gear 203. The inner wall of the slot 210 is inserted into the outer wall of the plate 209. The outer wall of the slide plate 211 is slidably connected to the inner wall of the plate 209. The outer wall of the slide plate 212 is slidably connected to the inner wall of the rack 205. The adjusting mechanism 3 includes several support legs 301. The support legs 301 can limit the movement trajectory of the top rod 307, so that it can only move up and down in a straight line along the direction of the support legs 301. At the same time, the support legs 301 can support the entire connecting plate 1. The outer walls of the several support legs 301 are all slidably connected to the bottom outer wall of the top plate 101. Each of the support legs 301 has a self-locking motor 302 fixedly connected to its outer wall. The bottom output ends of each of the self-locking motors 302 are fixedly connected to a worm gear 303 via a coupling. Since the worm gear 303 and the worm wheel 305 are meshed with each other, when the user starts the self-locking motor 302, the rotation of the self-locking motor 302 can drive the worm gear 303 to rotate, causing the worm wheel 305 to rotate. The outer wall of the worm gear 303 is rotatably connected to the inner wall of the support leg 301. Each of the support legs 301 has a rotating sleeve 304 rotatably connected to its inner wall. The rotating sleeve 304 can fix the worm wheel 305, preventing it from falling off, and at the same time, preventing the worm wheel 305 from disengaging from the worm gear 303.
[0033] A worm wheel 305 is fixedly connected to the outer wall of the rotating sleeve 304 near the worm 303. The outer wall of the worm wheel 305 meshes with the outer wall of the worm 303. Several arc-shaped grooves 306 are formed on the inner wall of the rotating sleeve 304. A push rod 307 is rotatably connected to the inner wall of each rotating sleeve 304. When the rotating sleeve 304 rotates, it can drive the push rod 307 to move through the arc-shaped grooves 306, causing the push rod 307 to rotate and gradually rise along the direction of the arc-shaped grooves 306. The top outer wall of the push rod 307 is fixedly connected to the bottom outer wall of the top plate 101. Several sliding rods 308 are fixedly connected to the outer wall of the push rod 307 near the arc-shaped grooves 306. The outer wall of the sliding rod 308 is slidably connected to the inner wall of the arc-shaped grooves 306. The sliding rods 308 can provide support for the push rod 307. In terms of transmission, when the rotating sleeve 304 rotates, it can drive the sliding rod 308 to move through the arc groove 306. When the sliding rod 308 moves, it will drive the top rod 307 to gradually rise. At the same time, the sliding rod 308 can prevent the top rod 307 from completely disengaging from the rotating sleeve 304. The inner wall of the support leg 301 is fixedly connected to the rotating sleeve 309. The inner wall of the rotating sleeve 309 near the sliding rod 308 has several arc grooves 310. The inner wall of the arc groove 310 is slidably connected to the outer wall of the arc groove 306. The controller 311 is fixedly connected to the outer wall of the left support leg 301. The arc groove 310 can limit the movement trajectory of the sliding rod 308, so that it can only move up and down in a straight line along the direction of the arc groove 310 within the arc groove 310.
[0034] One specific application of this embodiment is:
[0035] When workers need to use the equipment, the top plate 101 and the support legs 301 together can support the inner wall of the goaf retainer to prevent it from collapsing. When the width of the goaf retainer is different, the electric telescopic rod 204 can be activated simultaneously through the controller 311 to shorten it to a suitable length. When the electric telescopic rod 204 shortens, it will drive the gear 203 to rotate through the rack 205. When the gear 203 rotates, it can drive the rotating shaft 201 to rotate, which in turn causes the annular limit block 202 to rotate. When the annular limiting block 202 rotates, it can simultaneously pull the connecting rod 207 to move via the limiting shaft 206. When the connecting rod 207 moves, it will pull the locking plate 209 to slide on the sliding plate 211 via the limiting shaft 208, causing the locking plate 209 to gradually retract inward. When the locking plate 209 is completely pulled out of the slot 210 in the top plate 101, the top plate 101 can be directly pulled out from both ends of the connecting plate 1, and the length of the top plate 101 inserted into the connecting plate 1 can be readjusted. Then, the reverse... Start the electric telescopic boom 204, re-insert the clamping plate 209 into the adjusted slot 210, and re-fix the top plate 101. If it is necessary to adjust the height of the top plate 101 to suit different heights of gob-side entry, multiple self-locking motors 302 are started simultaneously via the controller 311. When the self-locking motors 302 rotate, they can drive the worm gear 303 to rotate, causing the worm wheel 305 to rotate. The rotation of the worm wheel 305 can drive the rotating rod sleeve 304 to rotate. When the rotating rod sleeve 304 rotates, it can... The sliding rod 308 on the top rod 307 is gradually rotated by the arc groove 306. Since the arc groove 310 on the rotating sleeve 309 restricts the movement trajectory of the sliding rod 308, it can only move up and down in a straight line. Therefore, under the restriction of the arc groove 306 and the arc groove 310, the rotation of the rotating sleeve 304 will drive the sliding rod 308 to gradually rise. When the sliding rod 308 rises, it can drive the top rod 307 to rise, which in turn can lift the top plate 101 and raise it.
