Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a tunnel construction material handling device. Background Technology

[0002] Currently, during tunnel construction, tunnel cover plates need to be transported. In this process, the cover plates are first secured with ropes, and then transported by multiple people carrying them or by forklift. However, since the installation position of the tunnel cable trench cover plates is 50-60cm above the road surface, the former method is inefficient and consumes more manpower. Furthermore, the height difference between the trench and the road surface at the installation position makes handling difficult and poses a significant safety risk. The latter method is more costly and may reduce economic benefits.

[0003] According to a tunnel construction material handling device (publication number: CN220785789U) disclosed above, the above application can significantly save manpower, reduce the labor intensity of workers and the difficulty of moving tunnel cover plates to a position higher than the road surface, effectively improve the transfer efficiency of tunnel cover plates and eliminate potential safety risks; this utility model can also be used in dimly lit spaces by setting a clamp for fixing a flashlight, making its application scope wider and making night construction safer and more reliable.

[0004] However, due to the different lengths of tunnel cover plates, when moving longer cover plates, the end of the horizontal axis that suspends the cover plate needs to be raised higher than the length of the cover plate, and the end of the horizontal axis that is located at the handle needs to be pressed down to the same height, which causes the handle to be close to the bottom surface, making it inconvenient for workers to push the entire handling device to move. Utility Model Content

[0005] The purpose of this invention is to provide a material handling device for tunnel construction to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel construction material handling device, comprising a horizontal shaft, a support, an axle, and wheels. A handle is fixedly connected to one end of the horizontal shaft, and a support plate is hinged to the other end of the horizontal shaft. A U-shaped plate is fixedly connected to the end of the support plate, and a fixed shaft is fixedly connected to the inner wall of the U-shaped plate. A hook chain is sleeved on the outer wall of the fixed shaft. An adjustment assembly is provided between the horizontal shaft and the support plate. The adjustment assembly includes a sleeve, which is slidably connected to the outer wall of the horizontal shaft. A traction plate is hinged to the surface of the sleeve, and the end of the traction plate away from the sleeve is hinged to the surface of the support plate. A fixed seat is fixedly connected to the outer wall of the horizontal shaft, and a through hole is opened on the side wall of the fixed seat, with a threaded rod threadedly connected in the through hole.

[0007] Preferably, a limiting component is provided on the side wall of the U-shaped plate. The limiting component includes a rod that passes through and is slidably connected to the side wall of the support plate. One end of the rod is in contact with the end of the fixed shaft, and the other end of the rod is fixedly connected to a side plate.

[0008] Preferably, the side wall of the side plate has a through hole, and a guide rod is slidably connected in the through hole. One end of the guide rod is fixedly connected to the side wall of the U-shaped plate, and the other end of the guide rod is fixedly connected to a protrusion.

[0009] Preferably, the protrusion and the side plate are elastically connected by a spring.

[0010] Preferably, one end of the threaded rod is fixedly connected to a rotating wheel, and the other end of the threaded rod is rotatably connected to a connecting seat, which is fixedly connected to the outer wall of the sleeve.

[0011] Preferably, a bracket is fixedly connected to the bottom surface of the horizontal shaft, an axle is fixedly connected to the bottom end of the bracket, and wheels are rotatably connected to both ends of the axle.

[0012] Compared with the prior art, the present invention provides a material handling device for tunnel construction, which has the following advantages:

[0013] 1. This tunnel construction material handling device can drive the sleeve to slide along the horizontal axis by rotating the wheel, and drive the support plate to rotate around the hinge point through the traction plate, so as to quickly adjust the tilt angle, improve the adaptability of the device to different construction scenarios, and effectively avoid the problem of inconvenience in handling due to differences in material specifications.

[0014] 2. The material handling device for tunnel construction uses a spring-driven insert rod that can always be tightly fitted to the end of the fixed shaft, avoiding the risk of the hook chain falling off the fixed shaft during handling. At the same time, when replacing the hook chain, simply pulling the side plate can separate the insert rod from the fixed shaft, making the operation simple and quick and shortening the time for hook chain replacement and maintenance.

Detailed Implementation

[0019] like Figures 1-3 As shown, this utility model provides a technical solution: a tunnel construction material handling device, including a horizontal shaft 1, a support 2, an axle 3, and wheels 31. The support 2 is fixedly connected to the bottom surface of the horizontal shaft 1, the axle 3 is fixedly connected to the bottom end of the support 2, and the wheels 31 are rotatably connected to both ends of the axle 3. The support 2, the axle 3, and the wheels 31 form the moving mechanism of the device, which enables the handling device to move conveniently in the tunnel and facilitates the transportation of materials.

[0020] A handle 11 is fixedly connected to one end of the horizontal shaft 1, and a support plate 12 is hinged to the other end of the horizontal shaft 1. A U-shaped plate 13 is fixedly connected to the end of the support plate 12. A fixed shaft 14 is fixedly connected to the inner wall of the U-shaped plate 13. A hook chain 15 is sleeved on the outer wall of the fixed shaft 14. The handle 11 is used to push the entire device to move, and by pressing down, one end of the horizontal shaft 1 moves downward and the other end tilts upward, so that the tunnel cover is lifted by the hook chain 15.

[0021] An adjusting assembly 4 is provided between the horizontal shaft 1 and the support plate 12. The adjusting assembly 4 includes a sleeve 41, which is slidably connected to the outer wall of the horizontal shaft 1. A traction plate 42 is hinged to the surface of the sleeve 41. The end of the traction plate 42 away from the sleeve 41 is hinged to the surface of the support plate 12. A fixed seat 43 is fixedly connected to the outer wall of the horizontal shaft 1. A through hole is opened on the side wall of the fixed seat 43, and a threaded rod 44 is threadedly connected to the through hole. One end of the threaded rod 44 is fixedly connected to a rotating wheel 45, and the other end of the threaded rod 44 is rotatably connected to a connecting seat 46, which is fixedly connected to the outer wall of the sleeve 41. The sleeve 41 is slidably connected to the horizontal shaft 1 and hinged to the support plate 12 through the traction plate 42. When the rotating wheel 45 is rotated, the threaded rod 44 rotates in the through hole of the fixed seat 43, driving the connecting seat 46 and the sleeve 41 to move on the horizontal shaft 1. Thus, the tilt angle of the support plate 12 is adjusted by the traction plate 42, which facilitates the adjustment of the height and position of the material.

[0022] A limiting component 5 is provided on the side wall of the U-shaped plate 13. The limiting component 5 includes a rod 51, which passes through and is slidably connected to the side wall of the support plate 12. One end of the rod 51 is in contact with the end of the fixed shaft 14, and the other end of the rod 51 is fixedly connected to a side plate 52. A through hole is provided on the side wall of the side plate 52, and a guide rod 53 is slidably connected in the through hole. One end of the guide rod 53 is fixedly connected to the side wall of the U-shaped plate 13, and the other end of the guide rod 53 is fixedly connected to a protrusion 54. The protrusion 54 and the side plate 52 are elastically connected by a spring 55. The function of the limiting component 5 is to prevent the hook chain 15 from falling off the fixed shaft 14 during transportation, ensuring the stability of the hook chain 15 and the material. The spring 55 can provide a certain elastic force to ensure that the insertion rod 51 is always in contact with the end of the fixed shaft 14. When the hook chain 15 needs to be replaced, simply pull the side plate 52 to move it axially along the guide rod 53, so that a gap is created between the insertion rod 51 and the fixed shaft 14, thereby facilitating the replacement of the hook chain 15.

[0023] In this utility model, during use, the operator rotates the rotating wheel 45, causing the threaded rod 44 to rotate within the through hole of the fixed seat 43. Since the threaded rod 44 is rotatably connected to the connecting seat 46, and the connecting seat 46 is fixed on the sleeve 41, the rotation of the threaded rod 44 is converted into the linear sliding of the sleeve 41 along the horizontal axis 1. When the sleeve 41 moves, the hinged traction plate 42 pulls or pushes the support plate 12 to rotate around its hinge point with the horizontal axis 1 until the tilt angle of the support plate 12 is adapted to the lifting requirements of the cover plate, and then the rotating wheel 45 is stopped.

[0024] Pull the side plate 52 away from the U-shaped plate 13. The side plate 52 slides along the guide rod 53 and compresses the spring 55. At the same time, it drives the insertion rod 51 to move away from the fixed shaft 14, so that a sufficient gap is formed between the insertion rod 51 and the end of the fixed shaft 14. Sleeve the hook chain 15 on the outer wall of the fixed shaft 14. Release the side plate 52. Under the elastic reset action, the spring 55 pushes the side plate 52 and the insertion rod 51 to move in opposite directions until the insertion rod 51 is tightly attached to the end of the fixed shaft 14 again. This completes the limiting and fixing of the hook chain 15 and prevents it from falling off the fixed shaft 14 during transportation.

[0025] Securely connect the end of the hook chain 15 away from the fixed shaft 14 to the lifting point of the tunnel cover. The operator holds the handle 11 and pushes the entire device. Through the cooperation of the axle 3 and the wheel 31, the device moves the cover to the designated position in the tunnel. If there is a height difference in the transportation path or the height of the cover needs to be finely adjusted, the handle 11 can be pressed down. Using the lever principle, the end of the horizontal shaft 1 closest to the handle 11 moves downward and the other end tilts upward. Through the support plate 12, U-shaped plate 13 and fixed shaft 14, the hook chain 15 and the cover are lifted to achieve fine-tuning of the height and ensure that the cover passes through obstacles smoothly.

[0026] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
