For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

[0024] Please refer to Figures 1-3 , a transportation and hoisting vehicle for municipal engineering pipelines, including a frame 1. A guide rod 2 is fixedly connected to the bottom surface of the frame 1, and a guide block 3 is slidably connected to the surface of the guide rod 2. A chain block 4 is arranged on the bottom surface of the guide block 3, and a pipe clamp 5 is installed at one end of the chain block 4.

[0025] In this implementation plan: The frame 1 includes a first support frame 11 and a second support frame 12, and the first support frame 11 and the second support frame 12 are connected by an adjusting assembly 10.

[0026] Specifically, it can adjust the distance between the first support frame 11 and the second support frame 12, achieving the purpose of flexibly adjusting the width of the frame 1, being able to adapt to more complex construction environments, facilitating use in narrow construction environments, having a wider scope of application, and stronger practicability.

[0027] In this implementation scheme: The adjusting assembly 10 includes a support base 101, a positive and negative thread lead screw 102, a moving block 103, a sliding groove 104, an adjusting rod 105, a hinge 106, a telescopic rod 107, and a handle 108. The positive and negative thread lead screw 102 is installed inside the support base 101 through a bearing block, and one end of the positive and negative thread lead screw 102 extends to the outside of the support base 101 and is installed with a handle 108. The surface of the positive and negative thread lead screw 102 is used in cooperation with the moving block 103. A sliding groove 104 is opened on the surface of the support base 101, and an adjusting rod 105 is slidably connected inside the sliding groove 104. One end of the adjusting rod 105 is hinged to the moving block 103 through a hinge 106, and the other end of the adjusting rod 105 is hinged to the second support frame 12 through a hinge 106. The telescopic rod 107 is fixed between the first support frame 11 and the second support frame 12.

[0028] Specifically, during use, the worker drives the positive and negative thread lead screw 102 to rotate forward and backward by rotating the handle 108 forward and backward. Under the limiting action of the sliding groove 104 and the adjusting rod 105, the two moving blocks 103 can be driven to approach or move away from each other, so as to adjust the distance between the first support frame 11 and the second support frame 12 through the action of the adjusting rod 105, achieving the purpose of flexibly adjusting the width of the frame 1, being able to adapt to more complex construction environments, facilitating use in narrow construction environments. Then, the pipeline clamping member 5 is used to clamp the pipeline. After that, when the frame 1 is pushed to the appropriate position, the pipeline is lowered into the foundation pit by the chain block 4, and then fine adjustment installation is carried out longitudinally by using the guide rod 2.

[0029] In this implementation scheme: A first strong magnet 7 is provided on the pipeline clamping member 5, and a second strong magnet 8 is magnetically attracted to the first strong magnet 7, and a protective pad 9 is installed on the surface of the second strong magnet 8 away from the first strong magnet 7.

[0030] Specifically, it is convenient to disassemble and assemble the protective pad 9, which is beneficial to replace the protective pad 9, and the operation is simple and convenient, with a low learning curve.

[0031] In this implementation scheme: Both the first support frame 11 and the second support frame 12 are welded from aluminum alloy pipes.

[0032] Specifically, while ensuring its own structural strength, the weight is reduced, making it more labor-saving to push.

[0033] In this implementation scheme: Moving wheels 6 are installed below both the first support frame 11 and the second support frame 12.

[0034] Specifically, it improves the convenience of movement during hoisting.

[0035] Working principle: During use, the staff drives the left - hand and right - hand screw rod 102 to rotate forward and backward by rotating the handle 108 forward and backward. Under the limiting action of the sliding groove 104 and the adjusting rod 105, the two moving blocks 103 can be driven to approach or move away from each other. Thus, under the action of the adjusting rod 105, the distance between the first support frame 11 and the second support frame 12 is adjusted, achieving the purpose of flexibly adjusting the width of the frame 1, being able to adapt to more complex construction environments, facilitating use in narrow construction environments. Then, the pipeline clamping member 5 is used to clamp the pipeline. After that, when the frame 1 is pushed to a suitable position, the pipeline is lowered into the foundation pit by the chain hoist 4, and then fine - tuning installation is carried out longitudinally using the guide rod 2.

[0036] The above - mentioned is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
