Description

Technical Field

[0001] This utility model relates to a water conservancy engineering construction machinery, and in particular to a lifting device suitable for water conservancy engineering construction. Background Technology

[0002] During water conservancy project construction, it is often necessary to install pipes and other items on walls or other high places. Installation requires first lifting the item to the installation position and then securing it firmly. For large items like pipes, cranes are typically used to lift them. However, cranes are prone to swaying due to the steel cable connecting the hook; furthermore, cranes cannot operate in situations such as under bridges, under buildings, or inside buildings. Utility Model Content

[0003] The technical objective of this utility model is to address the shortcomings of the existing technology by providing a lifting device for water conservancy engineering construction.

[0004] The technical solution of this utility model to solve its technical problem is: a lifting device for water conservancy engineering construction, characterized in that it includes a vehicle body, a boom, a forearm, and a bracket. The lower end of the boom is mounted on the vehicle body and hinged to it; the rear end of the forearm is hinged to the upper end of the boom, and the front end of the forearm is hinged to the bracket; each of the above hinge points is provided with a power device, which drives each component to rotate; the main body of the bracket has a V-shaped structure, and the front end of the bracket is provided with one or more parallel conveyor belt structures; the bracket contains multiple rollers.

[0005] The aforementioned power unit is a hydraulic cylinder, which drives the rotation of each component.

[0006] The aforementioned bracket includes multiple parallel V-shaped pieces, which are fixed into a single structure by connectors, forming gaps between the V-shaped pieces, and the conveyor belt and rollers are located in these gaps.

[0007] The aforementioned bracket is equipped with an electric motor or a hydraulic motor, which drives the conveyor belt to operate.

[0008] Compared with the prior art, the present invention has the following outstanding advantages:

[0009] 1. It can easily lift the pipe to a high place and facilitate installation;

[0010] 2. Construction can be carried out in narrow spaces such as underpasses and underground passages;

[0011] 3. Pipes can be easily picked up and placed into the trays via the conveyor belt, eliminating the need for manual handling. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model.

[0013] Figure 2 This is a schematic diagram of the bracket structure.

[0014] Figure 3 This is a diagram showing the working state of the utility model before loading the pipeline.

[0015] Figure 4 This is a diagram showing the working state of the utility model when supporting the pipeline. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1 to 4 As shown, this utility model includes a vehicle body 4, a boom 3, a forearm 2, and a bracket 1.

[0018] The lower end of the boom 3 is mounted on the vehicle body 4 and hinged to it. The rear end of the forearm 2 is hinged to the upper end of the boom 3, and the front end of the forearm 2 is hinged to the bracket 1. Each of the hinge points is equipped with a power device, which drives the rotation of each component. In the optimized solution, the power device is a hydraulic cylinder 5, which drives the rotation of each component.

[0019] like Figure 2 As shown, the main body of the bracket 1 has a V-shaped structure. One or more parallel conveyor belts 6 are located at the front end of the bracket 1. These conveyor belts 6 facilitate the retrieval of facilities such as underground pipes 9 into the bracket 1, thus saving manpower. The bracket 1 is equipped with an electric motor or hydraulic motor, which drives the conveyor belts 6.

[0020] The bracket 1 is equipped with multiple rollers 8. For the pipe 9, as... Figure 3 As shown, bracket 1 faces forward; when supporting pipe 9, as... Figure 4 As shown, bracket 1 faces upward; that is, the angle of bracket 1 will change when it is lifted, while the angle of pipe 9 remains unchanged (this means that pipe 9 has been connected into a whole long pipe 9 on the ground, not a short section of pipe 9). Therefore, pipe 9 will twist inside bracket 1. The action of roller 8 can reduce the friction of pipe 9 twisting and prevent pipe 9 from being scratched when twisting.

[0021] In the optimized solution, the bracket 1 includes multiple parallel V-shaped pieces, which are fixed into an integral structure by connectors, forming gaps between each V-shaped piece, and the conveyor belt 6 and roller 8 are located in these gaps.

[0022] The operation process is as follows: Figure 3As shown, in use, first lower the bracket 1 and insert the front end of the bracket 1 into the bottom of the pipe 9; then start the conveyor belt 6, and simultaneously slowly advance the bracket 1 forward, thereby picking up the pipe 9 and placing it into the bracket 1; then lift the bracket 1 and place the pipe 9 in the position to be installed, as shown. Figure 4 As shown.

[0023] This lifting device allows for the connection of individual pipe sections 9 into a single continuous pipe on the ground before installation. Ground-based connection is significantly more convenient than connecting pipes 9 at height.

[0024] It should be noted that the specific embodiments of this utility model have been described in detail. For those skilled in the art, all obvious changes made to it without departing from the spirit and scope of this utility model are within the protection scope of this utility model.
