Abstract

The invention discloses a pipe fixture which comprises an upper fixture block and a lower fixture block, a first connecting rod, a second connecting rod and a hydraulic cylinder. The upper fixture block is hinged with the lower block, and a cavity for accommodating a pipeline is formed between the upper fixture block and the lower fixture block. One end of the first connecting rod is hinged on the lower fixture block, and one end of the second connecting rod is hinged on the upper fixture block. The hydraulic cylinder is hinged on the lower fixture block. The other end of the first connecting rod and the other end of the second connecting rod are jointly hinged on a piston rod of the hydraulic cylinder. When the lower fixture block and the upper fixture block clamp the pipeline, the piston rod is in a maximum elongation state. The pipe fixture can clamp the pipeline even when gas leakage of the hydraulic cylinder or failure of a hydraulic lock occurs, so that safety performance of the pipe fixture is improved. The invention further discloses a pipe-conveying machine with the pipe fixture.

Description

technical field [0001] The invention relates to the field of clamps, more specifically, to a pipe clamp and a pipe transporting machine. Background technique [0002] At present, in the construction process, the pipeline transportation mostly adopts the crawler pipe transport machine, and the pipe clamps of the crawler pipe transport machine are as follows: figure 1 As mentioned above, it includes clamping arm 01 , movable bracket 02 , hydraulic cylinder 03 , piston rod 031 , first hinge shaft 04 , second hinge shaft 05 , and third hinge shaft 06 . The clamping arm 01 is hinged by the third hinge shaft 06 and the movable bracket 02, the hydraulic cylinder 03 is hinged by the second hinge shaft 05 and the movable bracket 02, and the piston rod 031 of the hydraulic cylinder 03 is hinged by the first hinge shaft 04 and the clamp The tight arm 01 is hinged. [0003] During the working process, the crawler pipe transport machine with the above-mentioned pipe clamp is close to t...
