A first auxiliary mechanism 4, a second auxiliary mechanism 5 and a third auxiliary mechanism 6 are installed on the equipment box 104, and a fourth auxiliary mechanism 8 is provided on the outer side of the front fixing plate 101. The first auxiliary mechanism 4, the second auxiliary mechanism 5, the third auxiliary mechanism 6 and the fourth auxiliary mechanism 8 are used together to replace the damaged hydraulic rod 303 in the unit bracket assembly 3.

[0020] Example 2 Please refer to Figure 3 As shown, the transport mechanism 2 includes a cylinder 201 rotatably connected to the top of the transport vehicle body 1, and a first screw rod 205 is rotatably connected inside the cylinder 201. A lifting member 208 is threadedly connected to the first screw rod 205, and the lifting member 208 is slidably installed on the first guide rod 206. The first guide rod 206 is welded in the cylinder 201, and a first stepper motor 207 for driving the first screw rod 205 to rotate is installed on the top of the cylinder 201. The top of the transport vehicle body 1 is also connected to a driving motor 202, and the output end of the driving motor 202 is fixedly connected to the driving gear 203. The bottom end of the outer wall of the cylinder 201 is fixedly installed with a driven gear 204, and the driving gear 203 is engaged with the driven gear 204.

[0021] Please refer to Figure 4As shown, the conveying mechanism 2 also includes a first threaded rod 210, a first fixed rod 211, a slide rail 214 and a telescopic member 216. A connecting frame 209 is welded to the outside of the lifting member 208. The first threaded rod 210 is rotatably connected to the connecting frame 209. The threads opened at both ends of the first threaded rod 210 rotate in opposite directions. The first fixed rod 211 is fixedly installed in the connecting frame 209. Two groups of movable seats 212 are slidably connected to the first fixed rod 211. The two groups of movable seats 212 are respectively threadedly connected to the two ends of the first threaded rod 210. A first servo motor 213 is installed on the outer wall of the connecting frame 209 to drive the first threaded rod 210 to rotate, and two groups of sliding seats 215 are slidably connected to the slide rail 214. The two ends on both sides of the telescopic member 216 are respectively rotatably connected to the two groups of movable seats 212 and the two groups of sliding seats 215. A multi-stage telescopic rod 217 is arranged between the lifting member 208 and the slide rail 214.

[0022] Please refer to Figure 4 As shown, a second threaded rod 218 is rotatably connected to the outer side of the slide rail 214. The second threaded rod 218 is provided with two groups of threaded threads with opposite rotation directions. Both ends of the threaded groups are threadedly connected to a clamping member 221. The clamping member 221 is slidably connected to the second fixed rod 219. The second fixed rod 219 is welded to the outer side of the slide rail 214. A second servo motor 220 is also provided on the outer side of the slide rail 214 to drive the second threaded rod 218 to rotate.

[0023] It can be understood by those skilled in the art that the output end of the driving motor 202 drives the driving teeth 203 to rotate, so that the driven teeth 204 and the cylinder 201 rotate as a whole, thereby changing the direction of the clamping member 221; the output end of the first stepper motor 207 drives the first screw rod 205 to rotate, so that the lifting member 208 moves up and down, thereby driving the clamping member 221 to move up and down; and the output end of the first servo motor 213 drives the first threaded rod 210 to rotate, so that the two sets of movable seats 212 move closer to or away from each other, thereby changing the direction of the two sets of sliding members 221. The seats 215 move closer to or farther from each other. When they move closer, the telescopic member 216 is in an extended state, thereby increasing the distance between the clamping member 221 and the cylinder 201. When they move farther away, the telescopic member 216 is in a retracted state, thereby reducing the distance between the clamping member 221 and the cylinder 201. The second threaded rod 218 is driven to rotate by the output end of the second servo motor 220, so that the two clamping members 221 on each threaded group are in a state of moving closer to or farther from each other, and when they move closer, the hydraulic rod 303 on the unit bracket assembly 3 is clamped and fixed.

[0024] Example 3 Please refer to Figure 2As shown, the unit bracket assembly 3 includes a base plate 301 and a support plate 302, two groups of hydraulic rods 303 are arranged between the base plate 301 and the support plate 302, two groups of first fixing blocks 304 are fixedly installed on the side of the base plate 301 and the support plate 302 close to each other, a third threaded rod 305 is rotatably connected between the two groups of first fixing blocks 304, the third threaded rod 305 is provided with two groups of thread groups with opposite thread rotation directions, and both ends of the thread group are threadedly connected with a clamping block 309, a third fixing rod 306 is further installed between the two groups of first fixing blocks 304, the clamping block 309 is slidably connected to the third fixing rod 306, the outer end of the third threaded rod 305 is connected to a rotating wheel 307, and a hexagonal groove 308 is provided on the outer side of the rotating wheel 307, and a clamping slot 310 adapted to the clamping block 309 is provided on the bottom end and telescopic end of the hydraulic rod 303.

[0025] Those skilled in the art can understand that, by rotating the rotating wheel 307, the third threaded rod 305 is rotated, and then the two blocks 309 on each thread group are in a state of approaching or moving away from each other, and when approaching, the blocks 309 can extend into the slot 310 on the hydraulic rod 303. Therefore, the hydraulic rod 303 in the present invention is fixed between the base plate 301 and the support plate 302 by clamping, which changes the traditional mining unit bracket that uses multiple bolts to fix the hydraulic rod 303.

[0026] Example 4 Please refer to Figure 8 and Figure 9 As shown, the first auxiliary mechanism 4 includes a fourth threaded rod 401 and a first electric push rod 405. The fourth threaded rod 401 is rotatably connected to the top inner part of the equipment box 104. The threads opened at both ends of the fourth threaded rod 401 have opposite rotation directions. Both ends of the outer surface of the fourth threaded rod 401 are threadedly connected with a clamping block 404. The outer end of the fourth threaded rod 401 is fixedly connected to the output end of the fourth servo motor 403. The fourth servo motor 403 is arranged on the outside of the equipment box 104. A fourth fixing rod 402 is also installed inside the top inner part of the equipment box 104. The clamping block 404 is slidably connected to the fourth fixing rod 402, and the first electric push rod 405 is fixedly installed on the rear side of the top of the equipment box 104. The output end of the first electric push rod 405 is fixedly connected to the mounting plate 406. A second electric push rod 407 is arranged on the outside of the mounting plate 406. The output end of the second electric push rod 407 is fixedly connected to the first double-headed cylinder 408 through a kit. Both output ends of the first double-headed cylinder 408 are fixedly installed with a pressing plate 409.

[0027] Those skilled in the art will understand that, by driving the fourth threaded rod 401 to rotate through the output end of the fourth servo motor 403, the two groups of clamping blocks 404 are moved closer to or away from each other; by extending or contracting the output end of the first electric push rod 405, the mounting plate 406 is moved upward or downward, thereby driving the two groups of clamping plates 409 to move up and down, and by controlling the extension or contraction of the two output ends of the first double-headed cylinder 408, the two groups of clamping plates 409 are driven closer to or away from each other.

[0028] Example 5 Please refer to Figure 10 As shown, the second auxiliary mechanism 5 includes two groups of second fixed blocks 501 welded on the right side of the equipment box 104, and a second guide rod 503 is installed between the two groups of second fixed blocks 501.

The output end of the third electric push rod 506 is also fixedly connected to the second double-headed cylinder 507 through a kit, and the two output ends of the second double-headed cylinder 507 are fixedly connected to the clamping piece 508.

[0029] Those skilled in the art will appreciate that, by driving the second screw rod 502 to rotate through the output end of the second stepper motor 504, the movable plate 505 is caused to reciprocate back and forth along the outer wall of the second guide rod 503, thereby driving the two groups of clamping members 508 to reciprocate back and forth along the outer wall of the second guide rod 503; by extending or contracting the output end of the third electric push rod 506, the second double-headed cylinder 507 is caused to move to the left or to the right, thereby driving the two groups of clamping members 508 to move to the left or to the right; and by controlling the extension or contraction of the two output ends of the second double-headed cylinder 507, the two groups of clamping members 508 are driven to move closer to or away from each other.

[0030] Example 6 Please refer to Figure 11As shown, the third auxiliary mechanism 6 includes a third screw rod 602, a third guide rod 603 and a lifting plate 605. A frame 601 is welded to the top front side of the equipment box 104. The third screw rod 602 is rotatably connected to the inside of the frame 601. The third guide rod 603 is fixedly connected to the inside of the frame 601. The lifting plate 605 is threadedly connected to the third screw rod 602. The lifting plate 605 is slidingly connected to the third guide rod 603.

The output end of the motor 606 is fixedly connected to the fourth electric push rod 607, and the output end of the fourth electric push rod 607 is installed with a hexagonal block 608.

[0031] Those skilled in the art will understand that, by driving the third screw rod 602 to rotate through the output end of the third stepper motor 604, the lifting plate 605 is moved up and down, thereby changing the height of the hexagonal block 608; and by driving the rotation of the output end of the motor 606, the fourth electric push rod 607 and the hexagonal block 608 are driven to rotate as a whole; and by controlling the extension or contraction of the output end of the fourth electric push rod 607, the hexagonal block 608 is driven to move backward or forward.

[0032] Example 7 Please refer to Figure 12 As shown, the power exchange mechanism 7 includes a fourth screw rod 701, which is rotatably connected in the equipment box 104, and the outer surface of the fourth screw rod 701 is threadedly connected to a moving block 704. A fifth electric push rod 705 is fixedly installed on the outside of the moving block 704. The output end of the fifth electric push rod 705 passes through the outer wall of the moving block 704 and is fixedly connected to the connecting plate 706. Two sets of joints are fixedly installed on the connecting plate 706, and the joints are adapted to the connecting groove 107. A fourth guide rod 702 is also welded in the equipment box 104, and the moving block 704 is slidably connected to the fourth guide rod 702. A fourth stepper motor 703 that drives the fourth screw rod 701 to rotate is installed on the outside of the equipment box 104.

[0033] Those skilled in the art will appreciate that all electricity used in the present invention is provided by the battery 106 in the equipment box 104, which changes the traditional form of diesel combustion and does not pollute the environment under the mine. When the battery 106 in use is low on power, the output end of the fifth electric push rod 705 contracts to pull the two sets of connectors out of the connection slot 107 on the battery 106 in use, and the output end of the fourth stepper motor 703 drives the fourth screw rod 701 to rotate again, so that the moving block 704 moves and reaches another unused battery 106. Finally, the output end of the fifth electric push rod 705 extends to insert the two sets of connectors into the connection slot 107 on the battery 106, thereby realizing power replacement without the need for manual operation by staff, ensuring that the transport vehicle body 1 can carry out long-term transportation under the mine.

[0035] Those skilled in the art can understand that, by driving the fifth screw rod 802 to rotate through the output end of the fifth stepper motor 804, the movable frame 805 is caused to reciprocate horizontally left and right, thereby driving the two groups of clamping blocks 812 to reciprocate horizontally left and right; by driving the sixth screw rod 806 to rotate through the output end of the sixth stepper motor 808, the movable plate 809 is caused to reciprocate back and forth, thereby driving the two groups of clamping blocks 812 to reciprocate back and forth; and by extending or contracting the output end of the sixth electric push rod 810, the two groups of clamping blocks 812 are driven to reciprocate up and down.

[0036] In order to clearly describe the working principle of the present invention, we use Figure 1 The following is an explanation of the azimuth perspective: S1. The transport vehicle body 1 travels to the corresponding working position through its own crawler tracks, and the transport mechanism 2 is set to change the direction of the four groups of clamping members 221, that is, to the "front, back, left, and right" sides, and also realizes the telescopic movement of the four groups of clamping members 221 in the "front, back, left, and right" directions. In the present invention, the telescopic movement is achieved by driving the telescopic member 216 to extend or contract. This structure is a multi-stage telescopic structure. Compared with the traditional driven telescopic structure, this structure can reduce the volume of the device in the fully contracted state, and realize the up and down movement of the four groups of clamping members 221, changing the height of the four groups of clamping members 221, and the four groups of clamping members 221 are used to clamp the two groups of hydraulic rods 303 on the unit support assembly 3. In summary, the transport mechanism 2 can be used to place the unit support assembly 3 at the corresponding working position between the two groups of fixed plates 101, and the left and right sides of the base plate 301 in the unit support assembly 3 are in contact with the limit plate 103, so that the several unit support assemblies 3 placed on the top of the transport vehicle body 1 will not fall over, meeting the needs of the staff; S2. When arranging the unit bracket assemblies 3 on the front and rear sides of the lane, the present invention first places a plurality of unit bracket assemblies 3 on the top of the transport vehicle body 1 for storage, and then sequentially arranges the stored plurality of unit bracket assemblies 3 on the front and rear sides of the lane. This changes the conventional method in which the transport vehicle only transports one unit bracket assembly 3 to the lane side in sequence, which is less practical. In addition, the conventional transport vehicle requires multiple reciprocating transport operations, which is less efficient. The use of the transport vehicle body 1 of the present invention can shorten the transport path to a certain extent, thereby improving efficiency. S3. The present invention also stores multiple healthy hydraulic rods 303 in the storage slot 102 at the top of the front fixed plate 101. If a group of hydraulic rods 303 in the unit bracket assembly 3 is damaged, resulting in its output end being unable to retract and extend, the unit bracket assembly 3 is transported to the top of the equipment box 104 by the transport mechanism 2, and the output end of the fourth servo motor 403 drives the fourth threaded rod 401 to rotate, so that the two groups of clamping blocks 404 approach each other to clamp the substrate 301 in the unit bracket assembly 3, and then the output end of the first electric push rod 405 is extended or contracted, so that the two groups of clamping plates 409 move up and down to a position that is adapted to the height of the support plate 302, and the output end of the second electric push rod 407 is extended so that the two groups of clamping plates 409 are respectively located at the top and bottom of the support plate 302, and then the two output ends of the first double-headed cylinder 408 are controlled to retract, so that the two groups of clamping plates 409 are driven to approach each other, thereby achieving clamping of the support plate 302 in the unit bracket assembly 3; S4. Secondly, the output end of the second stepper motor 504 drives the second screw rod 502 to rotate, so that the movable plate 505 moves back and forth, thereby driving the two sets of clamping members 508 to move to the right side of the undamaged hydraulic rod 303 in the unit bracket assembly 3. Then, the output end of the third electric push rod 506 is extended, so that the two sets of clamping members 508 move to the left and are respectively located at the front and rear sides of the undamaged hydraulic rod 303. Moreover, by controlling the contraction of the two output ends of the second double-headed cylinder 507, the two sets of clamping members 508 are driven to approach each other, thereby clamping the undamaged hydraulic rod 303. S5. The two sets of pressing blocks 812 in the fourth auxiliary mechanism 8 can move in the horizontal, vertical and vertical directions. First, the two sets of pressing blocks 812 move to the left side of the damaged hydraulic rod 303 in the unit bracket assembly 3, and the two sets of pressing blocks 812 fix the damaged hydraulic rod 303; S6. The output end of the third stepper motor 604 drives the third screw rod 602 to rotate, changing the height of the hexagonal block 608, so that the hexagonal block 608 moves to the front side of the two groups of rotating wheels 307 in sequence, and by driving the extension of the output end of the fourth electric push rod 607, the hexagonal block 608 is inserted into the hexagonal groove 308 on the rotating wheel 307 in sequence, and by driving the rotation of the output end of the motor 606, the two groups of third threaded rods 305 are driven to rotate in sequence, and then the two blocks 309 on each thread group are in a state of moving away from each other and disengaging from the inside of the card slot 310, thereby releasing the fixation of the two hydraulic rods 303 in the unit bracket assembly 3, and at this time, the two hydraulic rods 303 are respectively pressed by the two groups The fourth auxiliary mechanism 8 is used again to clamp the two groups of clamping blocks 812 to prevent it from falling over. The fourth auxiliary mechanism 8 is used again to make the two groups of clamping blocks 812 transfer the damaged hydraulic rod 303 to the storage slot 102 on the top of the rear fixed plate 101, and then the new hydraulic rod 303 in the storage slot 102 on the top of the front fixed plate 101 is transferred to the position of the original damaged hydraulic rod 303 by the two groups of clamping blocks 812, and then the two groups of third threaded rods 305 are driven in turn to rotate in the opposite direction, thereby fixing the two groups of hydraulic rods 303 between the base plate 301 and the support plate 302, thereby realizing the automatic replacement of the damaged hydraulic rod 303 in the unit bracket assembly 3, which is convenient and fast and meets the needs of the staff.
