A plurality of sliding seats 4 are evenly distributed on the monorail hanging track 1, and sliding seats are opened on the left and right sides of the underground monorail hanging track 1. The groove is provided with a running wheel on the sliding seat 4. The running wheel is driven by receiving a signal remotely. The running wheel is linked as a whole. The running wheel is installed on the sliding seat 4 to reduce friction during sliding and provide movement. When the device is moved, the running wheel rotates to move the position to ensure the smooth operation of the system, and slides with the underground monorail hanging track 1. The bottom end of the sliding seat 4 is fixedly connected with a linkage seat. The linkage seat is a concave-shaped frame with an opening downward. Two turntables 5 are symmetrically connected on the left and right sides of the groove of the linkage seat. The turntable 5 provides rotation support so that the first steel chain 6 can run smoothly. A first steel chain 6 is set on the turntable 5. One end of the first steel chain 6 is connected to the upper I-beam 7 through a fixed ring, and the other end is connected to the upper I-beam 7 through a fixed ring. The extension parts 10 at the left and right ends of the upper I-beam 7 are vertically erected downward, and the extension part 10 provides an extension space so that the pull-down part of the first steel chain 6 can be guided and limited in position. The left and right sides of the bottom end of the upper I-beam 7 are symmetrically connected with the second steel chains 9 extending vertically downward respectively. The other ends of the second steel chains 9 extend to the four corners of the top of the lower I-beam 8 respectively, and are connected through a fastening ring. The fastening ring and the release surface of the lower I-beam 8 are fastened by positioning bolts, and nuts are further fastened. A transfer machine is arranged between the upper I-beam 7 and the lower I-beam 8, and a slide groove 11 is provided on the lower I-beam 8. A clamping device is arranged on the slide groove 11. The extension part 10 is a rectangular trough body, and the front of the extension part 10 The rear two ends are symmetrically provided with positioning holes, and positioning bolts are inserted into the positioning holes. The positioning bolts penetrate the first steel chain 6 and the positioning holes and are fastened by nuts. The positioning holes and the positioning bolts fix the position of the first steel chain 6 to ensure the stability and safety of the system. It also includes guide wheels, which are arranged on the left and right sides of the extension part 10. The two guide wheels are attached to the first steel chain 6 to reduce friction when pulling the first steel chain 6, reducing the friction force of the first steel chain 6 in the extension part 10, so that the first steel chain 6 can move more smoothly when the device rises or falls. Chain grooves that match the first steel chain 6 are evenly provided on the circumference of the turntable 5 to provide stable power when pulling the first steel chain 6.
[0023] First, the tension anchor rod 3 is connected to the mounting seat 2 of the monorail crane track 1 through a zipper to hang the monorail crane track 1 in the underground tunnel. Subsequently, the device is installed, and sliding seats 4 are equidistantly arranged on the monorail crane track 1. The sliding seats 4 are provided with running wheels for movement. Next, the positioning bolts of the extension part 10 are pulled out, and the first steel chain 6 is lowered to the position of the transfer machine by rotating the turntable 5. Then, the lower I-beam 8 is inserted into the bottom end of the transfer machine, and the second steel chain 9 is connected to the fastening rings on the four corners of the lower I-beam 8. Subsequently, the first steel chain 6 is pulled to make it stuck in the corresponding chain grooves opened on the turntable 5 to increase the force and lift the device and the transfer machine. Subsequently, the positioning bolts are inserted, and the first steel chain 6 is tightened by nuts to limit the position. Finally, the running wheel is remotely operated to move the transfer machine.
[0024] Example 2: Please refer to Figure 2-3 , based on Example 1, it also has the following structure:
[0025] The clamping device includes a slide plate 12 and a threaded rod 13. The slide plate 12 is L-shaped and is respectively arranged on the left and right sides of the transfer machine frame for clamping the transfer machine frame. The slide plate 12 is slidably matched with the slide groove 11. A threaded groove is provided on the lateral end of the slide plate 12, and a threaded rod 13 is engaged in the threaded groove. The threaded rod 13 is rotated to adjust the distance between the two slide plates 12, thereby clamping or releasing the transfer machine frame. The lateral end of the slide plate 12 is higher than the bottom frame of the transfer machine to avoid collision with the transfer machine frame. The threaded grooves on the two slide plates 12 rotate in opposite directions, and the slide plates 12 move to opposite positions when the threaded rod 13 is rotated to clamp the transfer machine frame. The threaded grooves on the two slide plates 12 rotate in opposite directions. When the threaded rod 13 is rotated, the two slide plates 12 move to opposite positions. The positions are opposite, thereby clamping the transfer machine frame. Due to the design of the slide plate 12 and the clamping of the threaded rod 13, the transfer machine frame can be effectively fixed to reduce shaking and deviation during movement. The lateral end of the slide plate 12 is higher than the bottom frame of the transfer machine, which can avoid collision with the transfer machine frame, further ensuring safety and stability. In the initial state during operation, the slide plate 12 is fixed to the left and right sides of the transfer machine frame through the slide groove 11. By rotating the threaded rod 13, since the threaded grooves on the two slide plates 12 rotate in opposite directions, when the threaded rod 13 is rotated, the two slide plates 12 will move inward to clamp the transfer machine frame. The L-shaped design of the slide plate 12 ensures that it provides sufficient stability when clamping, and the height of the slide plate 12 ensures a safe distance from the bottom frame of the transfer machine to avoid collision and damage.
