Description

TECHNICAL FIELD

[0002] The water conservancy project is an engineering for controlling and allocating surface water and underground water in nature to achieve the purpose of eliminating harm and promoting benefits, and is also called a water project. In the water conservancy project, a pipeline needs to be laid. According to the prior art, a truck is generally used to transport the pipeline for a water conservancy project over a long distance. When the pipeline reaches a construction site, the pipeline is unloaded and placed in a centralized placement point. Then the pipeline is carried to a laying position one by one. Due to the limitation of the environment such as excavation of the construction site or narrow space, large mechanical equipment such as a crane and a loader cannot be used. Therefore, a small carrying device needs to be used to carry the pipeline.

[0003] The small carrying device usually adopts a cart. The pipeline is transported to the laying position one section by one section by using the cart. Although the cart can carry the pipeline and reduce labor, the cart itself does not have an unloading mechanism. The pipeline needs to be manually lifted for unloading or unloading mechanisms need to be arranged at two positions (the centralized placement point and the pipeline laying position) to lift the pipeline for unloading. Since the laying position changes at any time due to laying of the pipeline, the unloading mechanism needs to be moved for unloading. Therefore, the carrying device is inconvenient to use. Therefore, the application provides a carrying device for water conservancy projects. CONTENT OF THE UTILITY MODEL

[0029] As shown in the Figure 3 some embodiments, rubber pads 13 are arranged on the opposite sides of the two buckle frames 1103, preferably, the rubber pads 13 are arranged on the inner walls of the arc-shaped sections of the buckle frames 1103, by arranging the rubber pads 13, the contact friction between the buckle frames 1103 and the pipeline is increased, so that the pipeline is fixed more stably, ensuring the stability of hoisting.

[0030] As shown in the Figure 5 some embodiments, a limiting part 14 is connected between the sliding block 4 and the lifting part 11, the limiting part 14 is used to limit the stable lifting of the lifting part 11, since the steel wire rope 10 is a rope body, during hoisting, the pipeline will not fall, but will sway, by arranging the limiting part 14, the pipeline is prevented from swaying during hoisting, ensuring the stability of hoisting and lifting, not only facilitating the placement of the pipeline on the cart 1, but also facilitating the unloading of the pipeline into the pipeline trench.

[0031] As shown in the Figure 5 some embodiments, the limiting part 14 includes a limiting seat 1401 fixed on the shaft rod 1101, the steel wire rope 10 is connected with the limiting seat 1401, the limiting seat 1401 is provided with a limiting rod 1402 slidingly penetrating the sliding block 4 at the end, by arranging the limiting seat 1401 on the shaft rod 1101, and the limiting rod 1402 slidingly penetrating the sliding block 4 at the end is arranged on the limiting seat 1401, when the steel wire rope 10 is wound or unwound, the limiting seat 1401 is limited to vertical lifting by the limiting of the limiting rod 1402, and cannot sway, thereby ensuring the stability of the pipeline during hoisting.

[0032] As shown in the Figure 2 and Figure 5As shown in the drawings, in some embodiments, pulleys 15 are arranged on slider 4 and L-shaped frame 2, steel wire rope 10 is arranged on two pulleys 15 in sequence, preferably, pulley 15 on slider 4 is located in through slot 5, by arranging two pulleys 15, two pulleys 15 are respectively located at two bending end positions of steel wire rope 10, not only can play a guiding role on steel wire rope 10, but also make the collection of steel wire rope 10 more smooth, and make the pipe hoisting more labor-saving and smooth.
