The first sliding frame 601, the second sliding frame 603 and the third sliding frame 604 form a ladder, which is convenient for covering the foundation pit and allowing people to stand. The pushing component includes a driving screw 701. The outer side of the driving screw 701 is rotatably connected to a fixed plate 702. The fixed plate 702 is fixedly connected to the positioning column 3. The outer side of the driving screw 701 is connected to a sliding seat 703 through a nut pair. The outer side of the sliding seat 703 is provided with a threaded rod 606. A through groove is opened at one end of the threaded rod 606. The threaded rod 606 is rotatably connected to the sliding seat 703 by a bolt. The threaded rod 606 is threadedly connected to the threaded cylinder 605.

[0050] The pushing assembly also includes a first steering gear 704, which is fixedly connected to the bottom of the driving screw 701, and the outer side of the first steering gear 704 is meshed with the second steering gear 706.

A plurality of sliding grooves are provided on the outer side of the transmission shaft 705, and a transmission cylinder 707 is sleeved on the outer side of the transmission shaft 705. The inner wall of the transmission cylinder 707 is fixedly connected to a limit block 708 adapted to the plurality of sliding grooves. The outer side of the bidirectional screw 101 is fixedly connected to the second toothed synchronous wheel 710, and the outer side of the transmission cylinder 707 is fixedly connected to the first toothed synchronous wheel 709. The transmission cylinder 707 and the first toothed synchronous wheel 709 are connected by a toothed synchronous belt transmission.

[0051] Specifically, when construction workers need to carry out construction on the foundation pit, the operator rotates the bidirectional screw 101 so that the bidirectional screw 101 drives the two movable seats 104 connected on the outside by the nut pair to move, and then the two movable seats 104 move relative to each other, so that the movable seat 104 drives the movable column 4 above to move, and the movable column 4 pushes the support column 301 to move through the first rotating plate 304 and the second rotating plate 305, so that the movable column 4 approaches the positioning column 3, and the two movable columns 4 move away from each other, so that personnel can pass through the installation frame 1 into the construction site.

[0052] When the personnel rotates the bidirectional screw 101, the second toothed synchronous wheel 710 fixedly connected to the outside of the bidirectional screw 101 is driven by the second toothed synchronous wheel 710 and the first toothed synchronous wheel 709 through the toothed synchronous belt. The first toothed synchronous wheel 709 is fixedly connected with a limit block 708 inside, and the limit block 708 cooperates with the sliding groove on the outside of the transmission shaft 705, so that the transmission shaft 705 drives the second steering gear 706 to rotate, and the second steering gear 706 drives the first steering gear 704 to rotate, so that the first steering gear 704 drives the driving screw 701 to rotate, so that the sliding seat 703 descends, and the sliding seat 703 pushes the rotatably connected threaded rod 606, and the threaded rod 606 pushes the threaded cylinder 605, so that the threaded cylinder 605 pushes the third sliding frame 604 to slide out of the second sliding frame 603, and the second sliding frame 603 slides out of the first sliding frame 601 in sequence, forming a step shape, covering the foundation pit, making it convenient for personnel to walk and prevent personnel from falling into the foundation pit.

[0053] It is worth noting that the transmission cylinder 707 and the transmission shaft 705 can be installed by sliding, so that the toothed synchronous belt between the two second toothed synchronous wheels 710 and the transmission cylinder 707 can be installed and disassembled, and the threaded rod 606 can be rotatably installed inside the threaded cylinder 605, and then installed by passing the bolt through the threaded rod 606 and the sliding seat 703.

[0054] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 13 The spray assembly includes a connecting frame 501, with side panels 505 rotatably connected at both ends of the connecting frame 501. The side panels 505 are fixedly connected to the water tank 5. Multiple spray nozzles 502 for spraying are fixedly connected to the outside of the connecting frame 501. An electric push rod 503 is hinged between the water tank 5 and the connecting frame 501.

This can reduce dust at the construction site and clean the entire structure at the same time.

[0055] Specifically, a water tank 5 is installed on the upper part of the two positioning columns 3. After installation, water can be injected into the water tank 5, and a water pump is used to pump water into the water pipe 504, so that the water pipe 504 injects water into the connecting frame 501, and sprays dust through the nozzle 502. In addition, the electric push rod 503 can be started to push the connecting frame 501 to rotate, thereby adjusting the spraying angle.

[0056] Please refer again Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 10 、 Figure 11 and Figure 12 The driving assembly includes two transmission rods 203, both of which are rotatably connected to the support frame 2.

The two output ends of the dual-axis motor 202 are fixedly connected to the two rotating rods 201 respectively, so as to facilitate the movement of the entire device.

[0057] Specifically, when the entire device needs to be moved later, the dual-axis motor 202 inside the support frame 2 is started, so that the dual-axis motor 202 drives the rotating rod 201 to rotate, and the rotating rod 201 drives the worm 204 fixedly connected on the outside to rotate. When the worm 204 drives the meshing worm wheel 205 to rotate, when the worm wheel 205 drives the fixedly connected transmission rod 203 to rotate, the transmission rod 203 drives the fixedly connected gear 206 to rotate, so that the gear 206 pushes the rack 207 to move out of the support frame 2, contact the ground through the universal wheel 208, lift it up, and move it through the universal wheel 208.

[0058] Working principle: When the device needs to be used, it will be transported to the construction site, the support frame 2 will be placed on the ground, and then a group of positioning columns 3 and movable columns 4 will be installed, and the positioning socket 306 fixedly connected at the bottom of the positioning column 3 will be inserted into the positioning frame 102 on the top of the installation frame 1, and the positioning socket 306 at the bottom of the movable column 4 will be inserted into the positioning frame 102 on the upper part of the movable seat 104, and fixed and installed by bolts, and during the alignment of the positioning socket 306 with the movable seat 104, ensure that the insertion rod 307 at the bottom of the support column 301 is inserted into the sliding frame 103, and then another group of positioning columns 3 and movable columns 4 will be used for installation, and a support column 301 will be provided between the positioning column 3 and the movable column 4, and a first rotating plate 304 and a second rotating plate 305 that rotate crosswise are provided between the support column 301 and the positioning column 3 and the movable column 4, thereby blocking;

[0059] The operator rotates the bidirectional screw 101, causing the bidirectional screw 101 to drive the two movable seats 104 connected on the outside by the nut pair to move, thereby causing the two movable seats 104 to move relative to each other, causing the movable seats 104 to drive the movable column 4 above to move, so that the movable column 4 pushes the support column 301 to move through the first rotating plate 304 and the second rotating plate 305, thereby causing the movable column 4 to approach the positioning column 3, and the two movable columns 4 to move away from each other;

[0060] When a person rotates the bidirectional screw 101, the second toothed synchronous wheel 710 fixedly connected to the outside of the bidirectional screw 101 is driven by the second toothed synchronous wheel 710 and the first toothed synchronous wheel 709 through the toothed synchronous belt, and the first toothed synchronous wheel 709 is fixedly connected with the limiting block 708 inside, so that the transmission shaft 705 drives the second steering gear 706 to rotate, and the second steering gear 706 drives the first steering gear 704 to rotate, so that the first steering gear 704 drives the driving screw 701 to rotate, thereby causing the sliding seat 703 to descend, and the sliding seat 703 pushes the rotatably connected threaded rod 606, so that the threaded rod 606 pushes the threaded barrel 605, and then the threaded barrel 605 pushes the third sliding frame 604 to slide out of the second sliding frame 603, and causes the second sliding frame 603 to slide out of the first sliding frame 601 in sequence, forming a stepped shape to cover the foundation pit.
