Technical Field

[0001] This application relates to the technical field of construction engineering, and particularly relates to a hoist for construction engineering. Background Technique

[0002] At present, construction engineering refers to all technical work such as planning, surveying, design, construction, and completion for the new construction, renovation, or expansion of buildings and ancillary structures, as well as the completed engineering entities and the installation works of the supporting pipelines and equipment. It also refers to the construction works of various houses and buildings, also known as construction workload.

[0003] Hoists are essential in construction engineering. A hoist is a device that lifts materials to a specified height through a transmission mechanism.

[0004] Regarding the above related technologies, the inventor found the following defects: There are still some defects in existing lifting devices. Most of them use ropes to lift the required materials. During the lifting process, the ropes are prone to shaking, resulting in the sliding of the materials, which will cause the situation of material spilling, waste of materials, and affect the transportation efficiency. Moreover, the spilled materials are likely to pose a hazard to the ground construction workers. Utility Model Content

One end of the second rotating rod 7 far from the second runner 6 is rotatably connected to the concave block 2. The first rotating rod 3 can drive the first runner 5 to rotate. The first runner 5 can drive the second rotating wheel to rotate through the transmission of the crawler 4, so that the crawler 4 can rotate with the first runner 5 and the second runner 6 as fulcrums. Two first slide rails 8 are fixedly connected to the outer surface of the concave block 2. Two first sliders 9 are slidably connected to the outer surface of each first slide rail 8. A placement plate 10 is fixedly connected to the outer surfaces of the four first sliders 9. A first connecting block 11 is fixedly connected to the outer surface of the crawler 4. The inner wall of the first connecting block 11 is reinforced and connected by screws. The outer surface of the first connecting block 11 is fixedly connected to the placement plate 10. When the crawler 4 rotates, it can drive the first connecting block 11 to move up and down. The first connecting block 11 can drive the placement plate 10 to move up and down. The placement plate 10 drives the four first sliders 9 to slide on the corresponding first slide rails 8 to ensure the stable operation of the placement plate 10. Two limiters are provided on the outer surface of the concave block.

[0024] Please refer to Figure 2, on the side of the concave block 2 away from the first runner 5, there is a fixed connection with a cushion block 12. On the upper surface of the cushion block 12, there is a fixed installation of a motor 13. The output end of the motor 13 is fixedly connected to the first rotating rod 3. Starting the motor 13 can drive the first rotating rod 3 to rotate, and the cushion block 12 ensures the relative position of the motor 13.

[0025] Please refer to Figure 3 , on the upper surface of the placement plate 10, there is a rotatable connection with a first gear 14. On the outer surface of the first gear 14, there are two first racks 15 meshed. The first gear 14 can drive the two first racks 15 to move synchronously through meshing.

[0026] Please refer to Figure 3 , Figure 4 , inside the placement plate 10, there are two first rectangular grooves 16 opened. On the inner wall of each first rectangular groove 16, there is a sliding connection with a first fixed block 17. On the outer surface of each first fixed block 17, there is a corresponding fixed connection with a first rack 15. When the first rack 15 moves, it can drive the corresponding first fixed block 17 to slide inside the first rectangular groove 16. Through the mutual cooperation of the first rectangular groove 16 and the first fixed block 17, it can ensure that the corresponding first rack 15 does not disengage from the meshing with the first gear 14.

[0027] Please refer to Figure 4 , inside the placement plate 10, there is a second rectangular groove 18 opened. On the inner wall of the second rectangular groove 18, there is a sliding connection with a second connecting block 19. The second connecting block 19 can slide inside the second rectangular groove 18.

[0028] Please refer to Figure 4 , Figure 5 , on the upper surface of the second connecting block 19, there is a fixed connection with the corresponding first rack 15. On the outer surface of the second connecting block 19, there is a fixed connection with a telescopic rod 20. On the outer surface of the telescopic rod 20, there is a fixed connection with the placement plate 10. The telescopic rod 20 can drive the second connecting block 19 to slide inside the second rectangular groove 18, and the second connecting block 19 can drive the corresponding first rack 15 to move.

[0029] Please refer to Figure 4 , Figure 5 , on the upper surface of the placement plate 10, there are two second slide rails 21 fixedly connected. On the outer surface of each second slide rail 21, there are two second sliders 22 fixedly connected. On the upper surface of each two corresponding second sliders 22, there is a fixed connection with a baffle 23. The bottom surfaces of the two baffles 23 are fixedly connected to the corresponding first racks 15. There is a material storage box in contact with the upper surfaces of the two second slide rails 21. When the first rack 15 moves, it can drive the corresponding baffle 23 to move. The baffle 23 can drive the corresponding second slider 22 to slide on the corresponding first slide rail 8 to ensure the smooth operation of the baffle 23. When the two baffles 23 move towards each other, they can clamp the material placement box.

[0030] The implementation principle of an elevator for construction projects in an embodiment of this application is as follows: Start the telescopic rod 20. The telescopic rod 20 drives the movement of the rack 15 fixedly connected to the first connecting block 11. The rack 15 drives the rotation of the first gear 14 through meshing. The first gear 14 drives the movement of the rack 15 on the other side through meshing rotation. The rack 15 drives the corresponding baffle 23 to move. When the baffles 23 move towards each other, they can clamp the material placement box to prevent the material from spilling due to shaking during the upward movement. Then, start the motor 13 to drive the rotation of the first rotating rod 3 connected to the first runner 5. The first runner 5 drives the rotation of the second runner 6 through the transmission of the track 4, so that the track 4 can rotate with the first runner 5 and the second runner 6 as the fulcrums. The rotation of the track 4 can drive the up and down movement of the first connecting block 11. The first connecting block 11 can drive the movement of the placement plate 10. When the first connecting block 11 moves upward, it drives the placement plate 10 to move upward to achieve the effect of lifting the material.
