Description

Technical Field

[0001] The utility model relates to the technical field of transfer vehicles, in particular to a material transfer vehicle for civil engineering construction. Background Art

[0002] Building materials are various materials used in construction projects. There are many kinds of building materials, which can be roughly divided into: 1. Inorganic materials, which include metal materials (including ferrous metal materials and non-ferrous metal materials) and non-metallic materials (such as natural stone, burnt earth products, cement, concrete and silicate products, etc.). In construction sites, transfer vehicles are commonly used material transportation tools. However, the transfer vehicle relies entirely on two handles for workers to hold. When going downhill, it only relies on the hand strength to hold the handle and move slowly downward. This has a high risk factor. When the worker accidentally loses his grip when going downhill, the transfer vehicle will slide freely downward and is out of control, which is easy to cause safety accidents. Utility Model Content

[0003] In order to solve the above technical problems, the technical solution provided by the utility model is as follows: a civil engineering construction material transfer vehicle, comprising a transfer vehicle body and a handle, the handle being obliquely connected to the side of the transfer vehicle body, and a front wheel and a rear wheel being arranged at the bottom of the transfer vehicle body, characterized in that a brake device is installed at the bottom of the transfer vehicle body, the brake device comprises a telescopic rod, a rear wheel rotation adjustment rod, a front wheel rotation adjustment rod, a deceleration pressure plate, a deceleration wheel, a connecting shaft 1 and a connecting shaft 2, the telescopic rod is fixedly connected to one end of the rear wheel rotation adjustment rod through the connecting shaft 1, the other end of the rear wheel rotation adjustment rod is used to be fixedly connected to the deceleration pressure plate, and the middle part of the rear wheel rotation adjustment rod is rotatably connected through the rotating shaft 1;

[0004] The other end of the telescopic rod is fixedly connected to one end of the front wheel rotation adjustment rod through the second connecting shaft, and the other end of the front wheel rotation adjustment rod is used to be fixedly connected to the front wheel. The middle part of the front wheel rotation adjustment rod is rotationally connected through the second rotating shaft, and the reduction wheel is installed on the second rotating shaft. By controlling the shortening of the telescopic rod, the two ends of the telescopic rod drive the rear wheel rotation adjustment rod and the front wheel rotation adjustment rod to move inward, the rear wheel rotation adjustment rod drives the reduction pressure plate to press the rear wheel, and the front wheel rotation adjustment rod drives the front wheel to contact the reduction wheel to achieve deceleration.

[0005] Furthermore, two sets of front wheels are provided, and the reduction wheels do not contact the ground.

[0006] Furthermore, the rear wheels are provided in two groups, and the two groups of rear wheels are coaxially arranged.

[0007] The advantages of the utility model compared with the prior art are:

[0008] The brake device in the utility model adopts a combination of multiple structures such as a telescopic rod, a rear wheel rotation adjustment rod, a front wheel rotation adjustment rod, a deceleration pressure plate, a deceleration wheel, a connecting shaft one and a connecting shaft two. Therefore, when the above-mentioned transfer vehicle is in the process of transporting construction materials downhill, the telescopic rod can be controlled to be extended and retracted as needed to achieve braking and deceleration of the front and rear wheels, thereby avoiding the occurrence of dangerous accidents due to excessive speed of the above-mentioned material transfer vehicle in the process of going downhill, solving the problem that the staff in the prior art only rely on holding with their hands during the downhill process, and reducing the labor intensity of the staff.

[0009] The utility model has a loading vehicle frame detachably connected to the transfer vehicle body, so that the loading vehicle frame can be used to load cement, concrete, natural stone and other materials as needed, and the natural stone can also be disassembled to transport some construction pipes or cables and other materials. The vehicle has two uses and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] The utility model is described in detail with reference to the accompanying drawings.

[0019] The utility model provides a civil engineering construction material transfer vehicle during specific implementation, including a transfer vehicle body 1 and a handle 2, the handle 2 is obliquely connected to the side of the transfer vehicle body 1, a front wheel 3 and a rear wheel 4 are arranged at the bottom of the transfer vehicle body 1, and a brake device is installed at the bottom of the transfer vehicle body 1, the brake device includes a telescopic rod 5, a rear wheel rotation adjustment rod 6, a front wheel rotation adjustment rod 7, a deceleration pressure plate 8, a deceleration wheel 9, a connecting shaft 10 and a connecting shaft 2 11, the telescopic rod 5 is fixedly connected to one end of the rear wheel rotation adjustment rod 6 through the connecting shaft 10, the other end of the rear wheel rotation adjustment rod 6 is used to be fixedly connected to the deceleration pressure plate 8, and the middle part of the rear wheel rotation adjustment rod 6 is rotatably connected through a rotating shaft 12;

[0020] The other end of the telescopic rod 5 is fixedly connected to one end of the front wheel rotation adjustment rod 7 through the connecting shaft 2 11, and the other end of the front wheel rotation adjustment rod 7 is used to be fixedly connected to the front wheel 3. The middle part of the front wheel rotation adjustment rod 7 is rotationally connected through the rotating shaft 2 13. The reduction wheel 9 is installed on the rotating shaft 2 13. By controlling the telescopic rod 5 to shorten, the two ends of the telescopic rod 5 drive the rear wheel rotation adjustment rod 6 and the front wheel rotation adjustment rod 7 to move inward, the rear wheel rotation adjustment rod 6 drives the reduction pressure plate 8 to press the rear wheel 4, and the front wheel rotation adjustment rod 7 drives the front wheel 3 to contact the reduction wheel 9 to achieve deceleration.

[0021] Embodiment 1:

[0022] like Figure 3 , Figure 4 As shown, when the utility model is transporting construction materials, when the above-mentioned civil engineering construction material transport vehicle needs to slow down during the downhill process, the control button 18 can be adjusted upward by hand, and the control button 18 controls the telescopic rod 5 to shorten. The shortening of the rear end of the telescopic rod 5 drives the rear wheel rotation adjustment rod 6 to move inward, so that the middle part of the rear wheel rotation adjustment rod 6 moves downward along the rotation axis 10. At this time, the rear wheel rotation adjustment rod 6 drives the deceleration pressure plate 8 to press the rear wheel 4. When the telescopic rod 5 continues to extend and retract, the other end of the telescopic rod 5 moves inward, thereby driving one end of the front wheel rotation adjustment rod 7 to move inward, and the middle part of the front wheel rotation adjustment rod 7 rotates upward along the rotation axis 2 11, thereby driving the two front wheels 3 to press against the deceleration wheel 9 to achieve the deceleration process. The above-mentioned brake device for the civil engineering construction material transport vehicle only needs to manually operate the control button 18, which reduces the work intensity of the staff and provides convenience for the staff.

[0023] When deceleration is not needed, the telescopic rod 5 can be extended by adjusting the control button 18 downward. After the telescopic rod 5 is extended, it drives the rear wheel rotation adjustment rod 6 and the front wheel rotation adjustment rod 7 at both ends to rotate in the opposite direction in sequence. The rear wheel rotation adjustment rod 6 rotates to make the deceleration pressure plate 8 move upward, and the rear wheel 4 is freed from the restraint of the deceleration pressure plate. The front wheel rotation adjustment rod 7 rotates to drive the front wheel 3 away from the deceleration wheel 9 to free it from the restraint.

[0024] Embodiment 2:

[0025] like Figure 1 As shown, during use, the utility model can be directly used to load devices such as pipes or cables, and transport them using the transfer vehicle body 1, which is convenient to use.
