Description

Technical Field

[0001] The utility model relates to the technical field of handcarts, in particular to a handcart for building construction. Background Art

[0002] A handcart is a handling vehicle pushed or pulled by manpower. It is the ancestor of all vehicles. Although the material handling technology of handcarts has been continuously developing, handcarts are still used as indispensable handling tools to this day. Handcarts are widely used in production and life because of their low cost, simple maintenance, convenient operation, light self-weight, and the ability to work in places where motor vehicles are inconvenient to use. They are very convenient for short-distance handling of light items. The publication number CN211731405U includes a vehicle frame, an inclined plate, and a movable rod. One side of the front and back inner walls of the vehicle frame is fixedly connected with a clamping plate, and the surface of the inclined plate is slidably connected with the inner wall of the clamping plate. The top and bottom of the front and back of the vehicle frame are movably connected with clamping rods. One end of the clamping rod penetrates through the vehicle frame, the clamping plate, and the inclined plate and extends into the inside of the inclined plate. One end of the clamping rod is fixedly connected with a handle, and a spring is fixedly connected between the surface of the clamping rod and the side opposite to the handle and the vehicle frame. The utility model relates to the technical field of building construction. For this handcart for building construction, by fixedly connecting clamping plates on one side of the front and back inner walls of the vehicle frame, when discharging materials, the materials in the handcart can be emptied, which is convenient for operation. By fixedly connecting a limiting plate at the bottom of the inclined plate, it is convenient for workers to operate and also reduces the labor intensity of workers. Although this product can empty the materials in the hopper when discharging materials, it cannot adjust the height of the handcart. A handcart with a fixed height may require workers to bend down unnecessarily or have unnatural postures, increasing the physical consumption and inconvenience of work. Due to the inability to adjust the height according to specific needs, a handcart with a fixed height may cause inconvenience in operation and reduced efficiency during the work process, and improvement is needed.

However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: a wheelbarrow for construction, including a base 1, a hopper 2 and a support plate 3. The lower end of the base 1 is rotatably connected to a roller 4. A push handle 5 is fixedly installed on the side of the support plate 3. Support feet 6 are fixedly installed on the lower surface of the base 1. A motor A7 is fixedly installed on the side of the base 1 to rotate the bi-directional lead screw 8. The bi-directional lead screw 8 is rotatably connected inside the base 1, so that the sliding block A11 moves towards each other. A fixed block A9 is fixedly installed inside the base 1. A chute 10 is opened on the inner side of the base 1. A sliding block A11 is slidably connected inside the base 1 to install the linking rod A12. The linking rod A12 is rotatably connected to the side of the sliding block A11. A top plate 13 is fixedly installed on the lower surface of the support plate 3. A slide bar 14 is fixedly installed on the side of the fixed block A9. A sliding block B15 is slidably connected inside the top plate 13. An anti-slip pad 16 is fixedly installed on the outer surface of the push handle 5, which plays an anti-slip role when the staff grabs the push handle 5 and pushes.

[0025] Please refer to Figures 1-4, the output end of the motor A7 is fixedly connected to one end of the bidirectional lead screw 8. The bidirectional lead screw 8 is rotatably connected to the fixed block A9. By rotating the bidirectional lead screw 8 through the motor A7, the sliding blocks A11 can move towards each other, so that the linkage rod A12 can drive the top plate 13 to move upward. The bidirectional lead screw 8 is threadedly connected to the sliding blocks A11. The sliding blocks A11 are slidably connected to the slide rods 14 and slidably connected to the chutes 10. The slide rods 14 make the linkage rod A12 more stable during the process of driving the top plate 13 to rise, and the chutes 10 make the sliding blocks A11 slide more smoothly inside the base 1. The number of the fixed blocks A9 and the sliding blocks A11 is four groups. One end of the linkage rod A12 is rotatably connected to the side surface of the sliding plate B15. Through the linkage rod A12, the top plate 13 can move up and down, so as to adjust the height of the hopper 2.

[0026] Embodiment 2

[0027] Please refer to Figure 4 , 5 , a rotating block 17 is fixedly installed on the upper surface of the support plate 3, a rotating rod 18 is fixedly installed on the lower surface of the hopper 2, a mounting block 19 is fixedly installed on the surface of the support plate 3, a motor B20 is fixedly installed on the side surface of the mounting block 19, a threaded rod 21 is rotatably connected inside the mounting block 19, a sliding block C22 is slidably connected inside the support plate 3, a linkage rod B23 is rotatably connected to the side surface of the sliding block C22, and a connecting block 24 is fixedly installed on the lower surface of the hopper 2. The hopper 2 is driven to turn over and discharge materials through the linkage rod B23, so as to reduce the labor intensity of the operator, improve the convenience and work efficiency of the operator. The rotating rod 18 is rotatably connected to the rotating block 17. One end of the linkage rod B23 is rotatably connected to the outer surface of the connecting block 24. The design of the rotating rod 18 and the rotating block 17 enables the hopper 2 to turn over. By driving the hopper 2 to turn over and discharge materials through the linkage rod B23, the labor cost and labor intensity can be greatly reduced. The output end of the motor B20 is fixedly connected to one end of the threaded rod 21. The threaded rod 21 is threadedly connected to the sliding block C22. By rotating the threaded rod 21 through the motor B20, the sliding block C22 drives the linkage rod B23 to move, and the linkage rod B23 will lift the hopper 2 to realize turning over and discharging materials of the hopper 2.

[0028] Working principle: When in use, when it is necessary to unload the materials inside the hopper 2, first start the motor B20. The output end of the motor B20 will drive the threaded rod 21 to rotate inside the mounting block 19. Since the sliding block C22 is threadedly connected to the threaded rod 21, the threaded rod 21 drives the sliding block C22 to slide inside the base 1. When the sliding block C22 moves towards the direction close to the motor B20, at this time, the slide plate will drive the linkage rod B23 to exert a thrust on the hopper 2, so that the linkage rod B23 drives the hopper 2 to turn over and unload. When the sliding block C22 moves away from the motor B20, at this time, the sliding plate B will drive the linkage rod B23 to exert a pulling force on the hopper 2, causing the hopper 2 to reset. By using the linkage rod B23 to lift the hopper 2, the hopper 2 can be turned over and unloaded, avoiding the need for the operator to turn over the entire trolley during the unloading process. This loading and unloading process increases the labor intensity of the operator, thus improving the convenience and work efficiency of the staff. When it is necessary to adjust the height of the trolley, first start the motor A7. The motor A7 will drive the bidirectional lead screw 8 to rotate. Since the bidirectional lead screw 8 is threadedly connected to the sliding block A11, the sliding block A11 moves towards each other. At this time, the sliding block A11 will slide inside the chute 10 to make its movement smoother. During the movement of the sliding block A11, it will drive the linkage rod A12 to extend upward. At the same time, the sliding block A11 will slide on the surface of the slide rod 14 to make it more stable during the upward movement. At this time, the linkage rod A12 will move the support plate 3 and the hopper 2 up and down through the top plate 13, thus realizing the adjustment of the height of the trolley, so as to facilitate the use of the trolley by staff of different heights for work, enabling the staff to work more comfortably, reducing unnecessary bending or overstretching, and helping to reduce physical consumption and work fatigue. This can improve work efficiency, reduce operation time, and improve construction efficiency.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as the technical content of the technical solution of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
