[0004] However, in the existing technology, when workers are working on the floors, large materials are mainly lifted by tower cranes, and most small materials are usually carried by the workers themselves. When traditional handling devices are in use, they cannot be quickly transported to the upper floors and need to take a special elevator to be transported to the upper floors. This cannot achieve the purpose of fast transportation and affects the efficiency of construction. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the traditional transporting device in the prior art cannot be used to quickly transport to the upper floors and needs to take a special elevator to be transported to the upper floors, and a transport vehicle for use in construction sites is proposed.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a transport vehicle for use at a construction site, comprising a carrier plate, both sides of which are rotatably connected to rollers, a positioning plate fixedly mounted on the upper surface of the carrier plate, and a transport component movably mounted on the inner side of the positioning plate;

[0007] The transport assembly includes a rope, a fixed pulley and a movable pulley, the fixed pulley is installed on the top of the positioning plate, the movable pulley is located at the bottom of the positioning plate, the rope is wound around the surface of the fixed pulley and the surface of the movable pulley at the same time, a connecting frame is rotatably connected to the outer wall of the fixed pulley, the lower surface of the connecting frame is fixedly connected to a support plate, and the upper surface of the support plate is fixedly installed with a loading box.

[0008] Preferably, a positioning frame is rotatably connected to the outer wall of the fixed pulley, and the positioning frame is fixedly installed on the top of the positioning plate.

[0009] Preferably, extension rods are fixedly mounted on both sides of the connection frame, and the extension rods are slidably connected to the interior of the positioning plate.

[0010] Preferably, a limiting plate is fixedly mounted on one end of the extension rod, and one side of the limiting plate is overlapped on the outer wall of the positioning plate.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the utility model, a transport assembly consisting of a movable pulley, a fixed pulley and a rope as the main structure is provided, so that the transport vehicle can transport materials in a vertical direction. The fixed pulley can change the direction of the force, and the movable pulley can achieve the effect of saving effort.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model provides a transport vehicle for construction sites, comprising a carrier plate 1, with rollers 5 rotatably connected to both sides of the carrier plate 1, a positioning plate 2 fixedly mounted on the upper surface of the carrier plate 1, and a transport assembly 3 movably mounted inside the positioning plate 2;

[0025] The transport assembly 3 includes a rope 31, a fixed pulley 34, and a movable pulley 35. The fixed pulley 34 is mounted on the top of the positioning plate 2, and the movable pulley 35 is located at the bottom of the positioning plate 2. The rope 31 is wound around the surfaces of the fixed pulley 34 and the movable pulley 35 at the same time. The outer wall of the fixed pulley 34 is rotatably connected to a connecting frame 33. The lower surface of the connecting frame 33 is fixedly connected to a support plate 7. The upper surface of the support plate 7 is fixedly mounted with a loading box 4.

[0026] A positioning frame 32 is rotatably connected to the outer wall of the fixed pulley 34, and the positioning frame 32 is fixedly installed on the top of the positioning plate 2. One end of the rope 31 is fixedly connected to a hanging ring 38, and the hanging ring 38 is sleeved on the outer wall of the movable pulley 35. The other end of the rope 31 is fixedly connected to a pull ring 39.

[0027] The following describes in detail the specific configuration and function of this embodiment. The loading box 4 is used to load materials, the carrier plate 1 serves as the supporting structure of the entire transport vehicle, and the rollers 5 on both sides are used to ensure that it can move quickly on the construction site. In the process of transporting materials, the materials to be transported are first placed in the loading box 4, then the carrier plate 1 is moved to the target area, and then the loading box 4 is lifted to a higher place by the transport component 3, and finally the materials are taken out of the loading box 4.

[0028] When the transport assembly 3 is in use, the rope 31 is pulled through the pull ring 39. The rope 31 is wound around the surfaces of the fixed pulley 34 and the movable pulley 35. The eye 38 at the other end is sleeved on the surface of one of the movable pulleys 35. The loading box 4 is mounted on the support plate 7. The support plate 7 is fixedly connected to the connecting frame 33. When the rope 31 pulls the movable pulley 35 through the eye 38, the loading box 4 is pulled upward.

[0029] Because the movable pulley 35 is in a balanced state, the sum of the upward pulling forces is equal to the downward gravity. Since there are two sections of rope 31 pulling the pulley 35 upward, the operator can pull up the loading box 4 with less force, thereby achieving the purpose of quickly transporting materials.

[0030] Example 2: Figure 3 and Figure 4 As shown, extension rods 36 are fixedly installed on both sides of the connecting frame 33, and the extension rods 36 are slidably connected to the inside of the positioning plate 2. One end of the extension rod 36 is fixedly installed with a limiting plate 37, and one side of the limiting plate 37 is overlapped on the outer wall of the positioning plate 2. A strip hole 6 is opened at the intersection of the positioning plate 2 and the extension rod 36.

[0031] The effect achieved by the entire embodiment is that the extension rods 36 on both sides of the connecting frame 33 are in the strip holes 6 of the positioning plate 2. During the movement of the connecting frame 33, the extension rods 36 can limit the moving route of the connecting frame 33 to prevent the loading box 4 from rotating. The limiting plates 37 at the ends of the extension rods 36 are overlapped on the outer wall of the positioning plate 2, which can prevent the connecting frame 33 from shaking, thereby improving the stability of the loading box 4.

[0032] The method of use and working principle of this device are as follows: during the material transportation process, the materials to be transported are first placed in the loading box 4, then the carrier 1 is moved to the target area, and then the rope 31 is pulled through the pull ring 39, and the lifting ring 38 at the other end of the rope 31 is used to drive the connecting frame 33 to move upward. During the upward movement of the connecting frame 33, the loading box 4 is synchronously driven by the support plate 7, thereby achieving the purpose of transporting materials in the vertical direction;

[0033] During the movement of the loading box 4, the extension rod 36 can limit the movement path of the connecting frame 33 and, when used in conjunction with the limiting piece 37, can prevent the loading box 4 from rotating.

[0034] Because the movable pulley 35 is in a balanced state, the sum of the upward pulling forces is equal to the downward gravity. Because there are two sections of rope 31 pulling the pulley 35 upward, the operator can pull up the loading box 4 with less force, which can achieve the purpose of quickly transporting materials. Finally, after the loading box 4 is moved to a high place, the materials can be taken out of the loading box 4.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
