[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 The utility model provides an embodiment: a material handling device for tunnel construction, including a base plate 1, which supports a cargo box 2. The top of the base plate 1 is provided with a cargo box 2 through an adjusting component 4. The height and the tilt angle of the cargo box 2 are adjusted through the adjusting component 4. The materials are collected and transported through the cargo box 2. The bottom of the base plate 1 is fixedly connected with rollers 3 through a buffer component 5. The buffer component 5 improves the buffering effect of the base plate 1 and reduces the shaking of the cargo box 2. The rollers 3 are arranged in four groups in an array, and the four groups of rollers 3 are convenient for the staff to move the base plate 1.

[0033] Reference Figure 1-Figure 3 The adjustment component 4 includes a slider 41, and the front side of the slider 41 is hinged with a hinge rod 42. The movement of the hinge rod 42 drives the support rod 43 to rotate, and at the same time drives the cargo box 2 to move. The back side of the hinge rod 42 is hinged with a support rod 43, and the support rod 43 supports and limits the hinge rod 42. A slide groove 44 is opened on the top of the bottom plate 1, and there are two groups of slide grooves 44 symmetrically distributed.

[0034] Reference Figure 1 and Figure 4 The buffer assembly 5 includes a shell 51, and the inner wall of the shell 51 is elastically connected to a cylindrical rod 54 through a spring 53. The elastic force of the spring 53 plays a buffering role on the cylindrical rod 54, thereby reducing a portion of the impact load on the cylindrical rod 54. The inner wall of the shell 51 is fixedly connected to a damping sleeve 52, and the damping sleeve 52 slows down the moving speed of the cylindrical rod 54 when it is impacted, thereby playing a buffering role on the cylindrical rod 54.

[0035] Reference Figure 2 A fixing plate 45 is fixedly connected to the top of the base plate 1. The fixing effect of the fixing plate 45 keeps the two sets of electric telescopic rods 46 fixed. The left side of the fixing plate 45 is fixedly connected to the electric telescopic rod 46. The fixing effect of the electric telescopic rod 46 prevents the electric telescopic rod 46 from falling off. The electric telescopic rod 46 is a prior art and has the functions of extension and contraction.

[0036] Reference Figure 1 The top of the hinged rod 42 is hinged to the bottom left end of the cargo box 2, and there are two groups of hinged rods 42 symmetrically distributed. When the two groups of hinged rods 42 move at the same time, the cargo box 2 is driven to move vertically as a whole. When one group of hinged rods 42 moves, it drives the cargo box 2 to rotate at the top hinge point of the other group of hinged rods 42 to tilt. The bottom of the support rod 43 is hinged to the top left end of the bottom plate 1, and there are two groups of support rods 43 symmetrically distributed.

[0037] Reference Figure 1 and Figure 2 The slider 41 is slidably connected to the inner wall of the slide groove 44. The sliding effect of the slider 41 drives the hinged rod 42 to move. There are two groups of sliders 41. The two groups of sliders 41 are symmetrically distributed along the center line of the bottom plate 1. By providing two groups of sliders 41, the two groups of hinged rods 42 can be driven to move respectively.

[0038] Reference Figure 4 One end of the spring 53 is fixedly connected to the inner wall of the shell 51, and the other end of the spring 53 is fixedly connected to the bottom of the cylindrical rod 54. The fixing effect of the spring 53 prevents the spring 53 from falling off. The bottom of the shell 51 is fixedly connected to the top of the roller 3. The fixing effect of the roller 3 prevents the roller 3 from falling off.

[0039] Reference Figure 2 The output end of the electric telescopic rod 46 is fixedly connected to the right side of the slider 41. By starting the electric telescopic rod 46, the slider 41 is driven to slide. Two groups of electric telescopic rods 46 are provided. The two groups of electric telescopic rods 46 are symmetrically distributed along the center line of the fixed plate 45. By providing two groups of electric telescopic rods 46, the two groups of sliders 41 can be driven to move respectively.

[0040] Reference Figure 4 The outer periphery of the cylindrical rod 54 is slidably connected to the inner wall of the shell 51. The sliding effect of the cylindrical rod 54 squeezes the spring 53 and the damping sleeve 52, thereby being buffered by the spring 53 and the damping sleeve 52. The top of the cylindrical rod 54 is fixedly connected to the bottom of the base plate 1, and the fixing effect of the cylindrical rod 54 prevents the cylindrical rod 54 from falling off.

[0041] Working principle: When the staff needs to move materials in the tunnel, the staff moves the base plate 1 to the specified position and controls the two sets of electric telescopic rods 46 to start at the same time, so that the two sets of electric telescopic rods 46 simultaneously drive the two sets of sliders 41 to slide along the inner wall of the slide groove 44, and at the same time drive the two sets of articulated rods 42 to move, so that the support rod 43 rotates along the bottom hinge point, and the two sets of articulated rods 42 drive the cargo box 2 to move vertically as a whole, thereby adjusting the overall height of the cargo box 2.

[0042] When the tilt angle of the cargo box 2 needs to be adjusted, the staff controls a group of electric telescopic rods 46 to drive a group of sliders 41 to slide along the inner walls of a group of slide grooves 44, thereby moving a group of hinged rods 42. The group of hinged rods 42 drives the cargo box 2 to rotate with the top hinge point of another group of hinged rods 42 as the center, thereby tilting the cargo box 2 as a whole, making it easier for the staff to load and unload materials.

[0043] When the cargo box 2 is filled with materials for moving and transportation, when encountering an uneven road surface, the cylindrical rod 54 slides downward along the inner wall of the shell 51, and the spring 53 and the damping sleeve 52 are squeezed by the cylindrical rod 54. The damping sleeve 52 slows down the movement speed of the cylindrical rod 54, and at the same time, a part of the impact force on the cylindrical rod 54 is reduced. The elastic force of the spring 53 further reduces the impact force on the cylindrical rod 54, which has a buffering effect on the bottom plate 1 and the cargo box 2 at the same time, so that the bottom plate 1 moves more smoothly.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
