Problems solved by technology
Because the outer wall of the pipe is very smooth, it is difficult to clamp the pipe, and it is difficult to accurately control the tightening force. Insufficient tightening torque or excessive torque will cause the pipe seal to fail, increase the probability of pipe leakage accidents, and lead to increased maintenance costs.
At the same time, when installing pipes, ordinary manual pipe wrenches may not work consistently due to angle problems, resulting in cumbersome and inefficient operations

Embodiment Construction
[0025] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] Such as figure 1 As shown, the embodiment of the present invention provides a wrench for connecting FRP pipes, including a handle 5, a clamp 1, a power system, a transmission system, a ferrule 10 and a force measuring system. One end of the handle 5 is provided with an accommodating cavity, and the power system and transmission system are arranged in the accommodating cavity. One end of the clamp 1 passes through the upper end of the accommodating cavity, and a U-shaped jaw is formed between the other end of the clamp 1 and the accommodating cavity, which serves to clamp the pipeline and provides a force-bearing fulcrum. The clamp 1 adjusts the size of the U-shaped jaw through the rotary wheel 3 and tightens the glass fiber reinforced plastic pipe 9 . The upper end of the accommodating cavity is provided with a lockin...

The invention relates to the technical field of pipeline construction, in particular to a controllable-torque pipeline spanner for fiber reinforced plastic pipeline connection. The spanner comprises a handle, a clamp, a motive power system, a transmission system and a clamp sleeve, wherein the handle is connected with the clamp, a rotating wheel is arranged on the clamp, the rotating wheel is in direct contact with a fiber reinforced plastic pipeline, the clamp sleeve tightly covers the fiber reinforced plastic pipeline, the motive power system is connected with the transmission system, the transmission system is connected with the clamp sleeve, and the transmission system drives the clamp sleeve to rotate, so the fiber reinforced plastic pipeline is driven to rotate. The controllable-torque pipeline spanner has the advantages that brake accessories on a tank body can be fast and accurately assembled, the whole vehicle manufacture quality influence caused by frequent repair of the brake assembly because of inaccurate accessory assembly is avoided, the production efficiency is improved, and high economic values and social values are realized.
Description
technical field [0001] The invention relates to the technical field of pipeline construction, in particular to a pipeline wrench with controllable torque for connecting glass fiber reinforced plastic pipelines. Background technique [0002] Fiberglass pipes are generally connected by threaded connections. Because the outer wall of the pipeline is very smooth, it is difficult to clamp the pipeline, and it is difficult to accurately control the tightening force. Insufficient tightening torque or excessive torque will cause the failure of the pipeline seal, increase the probability of pipeline leakage accidents, and lead to increased maintenance costs. At the same time, when installing pipes, ordinary manual pipe wrenches may not work consistently due to angle problems, resulting in cumbersome and inefficient operations. Contents of the invention [0003] The object of the present invention is to provide a wrench for connecting FRP pipes, which is easy to operate and labor-s...
