Description

Technical Field

[0001] The utility model relates to the technical field related to tunnel transportation, in particular to a transport flatbed truck with a built-in light source for tunnel construction. Background Art

[0002] The transport pallet truck for tunnel construction is a device used to transport construction materials during tunnel construction. It can reduce the tediousness of manual handling and is widely used in the field of construction auxiliary equipment. Since the working and transportation environment of tunnel engineering is mostly dark, the transport pallet truck is usually equipped with lighting facilities.

[0003] The existing self-contained light transport truck for tunnel construction includes a frame, a handle and a headlight. Generally, the headlight is arranged at the front end of the frame. When the transported items are unloaded, the frame will tip over and fall into the designated area, which makes it easy for the items to interfere with the headlight during unloading. The headlight is damaged by the impact of the items, resulting in a reduction in the service life of the headlight. In addition, the lighting work must be manually controlled when the headlight is finished, which increases the workload of the staff. Utility Model Content

[0004] The utility model aims to provide a transport panel truck with built-in light source for tunnel construction, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A transport truck with a self-contained light source for tunnel construction comprises a frame and a light slidably mounted on one end of the frame, a wheel assembly is rotatably mounted on the frame, and the wheel assembly is arranged at a position away from the center of the frame.

[0007] It also includes symmetrically arranged elastic telescopic parts, which are installed on the frame, away from one end of the wheel assembly, and connected to the light;

[0008] The conductive component is slidably mounted on the frame and connected to the elastic telescopic component. When the elastic telescopic component is deformed in contact with the ground, the conductive component is triggered to separate from the headlight, and the headlight is retracted to the inner side of the frame.

[0009] As described above, the transport truck with built-in light source for tunnel construction has symmetrically arranged inner grooves formed on the side of the frame away from the wheel assembly, and the light is slidably arranged in the inner grooves.

[0010] The transport truck with built-in light source for tunnel construction as described above: a conductive sheet is fixedly connected to the bottom of the lamp.

[0011] The transport truck with self-contained light source for tunnel construction as described above: the elastic telescopic member comprises a plug-in cylinder and a plug-in shaft, the plug-in cylinder is fixedly mounted on the bottom of the vehicle frame, and the plug-in shaft is slidably mounted in the plug-in cylinder;

[0012] It also includes a spring, which is arranged on the inner side of the plug-in cylinder, one end of the spring abuts against the inner top of the plug-in cylinder, and the other end abuts against the plug-in shaft.

[0013] As described above, the transport cart with built-in light source for tunnel construction: a sleeve is connected to the end of the plug-in shaft away from the plug-in cylinder, a connecting rod is rotatably mounted on the sleeve, and the end of the connecting rod away from the sleeve is rotatably connected to the extended end of the lamp.

[0014] The transport truck with its own light source for tunnel construction as described above: the conductive component comprises a columnar member, the columnar member is rotatably mounted on the plug-in cylinder, one end of the columnar member is formed with a thread groove, and the other end is formed with an external thread, the external thread is threadedly connected with a threaded sleeve slidably mounted on the vehicle frame, and a battery is detachably mounted on the threaded sleeve;

[0015] It also includes a sleeve, which is arranged along the axial direction of the columnar component, and a ball matched with the thread groove is movably arranged in the sleeve.

[0016] As described above, for the transport truck with built-in light source for tunnel construction: a limiting sliding groove is formed on the plug-in cylinder, and the plug-in cylinder is fixedly connected to the sleeve via the limiting sliding groove.

[0017] Compared with the prior art, the utility model has the following beneficial effects: by adopting the lever principle, when one end of the frame stops driving, the frame tilts toward the side away from the wheel assembly, so that the elastic telescopic part is squeezed by the ground and deformed, thereby controlling the light to be retracted to the inside of the frame, and triggering the conductive component to separate from the light. When the light is retracted to the inside of the frame, the power supply is lost, and the light stops lighting, so that the light can be automatically powered off when the cart stops transporting.

The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0026] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0027] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0028] See also Figure 1 to Figure 6 In an embodiment of the utility model, a transport truck with its own light source for tunnel construction includes a frame 1, a light 2, a wheel assembly 13, an elastic telescopic member, and a conductive assembly.

[0029] The details are as follows, including:

[0030] See also Figure 1 , Figure 1 , a frame 1 and a headlight 2 slidably mounted on one end of the frame 1, a wheel assembly 13 is rotatably mounted on the frame 1, and the wheel assembly 13 is arranged at a position away from the center of the frame 1,

[0031] It also includes a symmetrically arranged elastic telescopic member, which is installed on the frame 1, away from the end of the wheel assembly 13, and connected to the light 2;

[0032] The conductive component is slidably mounted on the frame 1 and connected to the elastic telescopic member. When the elastic telescopic member is deformed in contact with the ground, the conductive component is triggered to separate from the headlight 2, and the headlight 2 is retracted to the inner side of the frame 1.

[0033] In detail, in this example, the transport cart with its own light source for tunnel construction described in the utility model is used. When in use, the lever principle is adopted. When one end of the frame 1 stops driving, the frame 1 tilts toward the side away from the wheel assembly 13, so that the elastic telescopic part is squeezed by the ground and deformed, thereby controlling the light 2 to be retracted to the inside of the frame 1, and triggering the conductive component to separate from the light 2. When the light 2 is retracted to the inside of the frame 1, the power supply is lost, and the light 2 stops lighting work, so that the light 2 can be automatically powered off when the cart stops transporting.

[0034] Preferably, a symmetrically arranged embedded groove 101 is formed on one side of the frame 1 away from the wheel assembly 13, and the headlight 2 is slidably arranged in the embedded groove 101, wherein a limiting end 102 is formed in the embedded groove 101, so that the headlight 2 is limited by the limiting end 102, and the headlight 2 cannot extend out of the frame 1 and collide with external obstacles to be damaged.

[0035] Preferably, a conductive sheet 3 is fixedly connected to the bottom of the lamp 2 .

[0036] See also Figure 3 The elastic telescopic member includes a plug-in tube 7 and a plug-in shaft 5. The plug-in tube 7 is fixedly mounted on the bottom of the frame 1, and the plug-in shaft 5 is slidably mounted in the plug-in tube 7;

[0037] It also includes a spring 8 , which is arranged inside the plug-in tube 7 , with one end of the spring 8 abutting against the top of the inner side of the plug-in tube 7 , and the other end of the spring 8 abutting against the plug-in shaft 5 .

[0038] The end of the plug-in shaft 5 away from the plug-in cylinder 7 is connected with a sleeve 6, and a connecting rod 4 is rotatably mounted on the sleeve 6. The end of the connecting rod 4 away from the sleeve 6 is rotatably connected to the extended end of the lamp 2.

[0039] In detail, when the frame 1 tilts toward one end, the plug-in shaft 5 is squeezed by the ground, causing the plug-in shaft 5 to move along the axial direction of the plug-in tube 7, and the spring 8 is compressed to reserve elastic potential energy. When the plug-in shaft 5 moves, it drives the sleeve 6 to move synchronously. Under the action of the connecting rod 4, the headlight 2 is driven to slide in the embedded groove 101, so that the headlight 2 is retracted to the inner side of the frame 1, so that the headlight 2 can be protected in the frame 1 when in use.

[0040] See also Figure 4The conductive component includes a columnar member 10, which is rotatably mounted on the plug-in barrel 7. A thread groove is formed at one end of the columnar member 10, and an external thread is formed at the other end. The external thread is threadedly connected to a threaded sleeve 11 slidably mounted on the frame 1. A battery 12 is detachably mounted on the threaded sleeve 11.

[0041] It also includes a sleeve 9, which is arranged along the axial direction of the columnar member 10, and a ball 901 adapted to the thread groove is movably arranged in the sleeve 9.

[0042] A limiting sliding groove 701 is formed on the plug-in cylinder 7 , and the plug-in cylinder 7 is fixedly connected to the sleeve 9 via the limiting sliding groove 701 .

[0043] Furthermore, when the above-mentioned plug-in shaft 5 moves, it drives the sleeve 9 to move synchronously. When the sleeve 9 moves, it drives the ball 901 to follow the movement. When the ball 901 moves, the threaded groove generates an inclined extrusion force, causing the cylindrical member 10 to rotate. When the cylindrical member 10 rotates, it drives the threaded sleeve 11 to make a linear motion along the axial direction of the cylindrical member 10. When the threaded sleeve 11 moves, it drives the battery 12 to move, so that when the lamp 2 moves to the end of the stroke, the battery 12 abuts against the conductive sheet 3, so that the lamp 2 is connected to the power supply and the lighting work is restored.

[0044] It should be noted that at least one group of strip sliders 1101 is formed on the threaded sleeve 11, and a through groove for relative sliding of the threaded sleeve 11 is formed on the frame 1. A strip sliding groove that slides with the strip slider 1101 is formed on the inner wall of the through groove, thereby realizing the sliding connection between the threaded sleeve 11 and the through groove.
