SUMMARY

[0003] The main purpose of the utility model is to effectively solve the problems in the background art.

[0004] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows: a high strength MPP cable protection pipe's connecting device, including the fixed clamp connected with the pipeline, the movable clamp connected with another pipeline and the plurality of drivers connected with the fixed clamp and also connected with the movable clamp, characterized by: further including the semicircular arc conical jacket arranged on the fixed clamp and the movable clamp and replaceable according to the diameter of the pipeline.

[0005] Preferably, the fixed clamp and the movable clamp are both openable clamps, each including clamp one, clamp two, bearing connecting clamp one and clamp two, and lock buckle.

[0006] Preferably, the clamp one and the clamp two are both provided with guide grooves matched with the semicircular arc conical jacket.

[0007] Preferably, the driver is any one of pneumatic cylinder, hydraulic cylinder, electric push cylinder, electric gear rack driving mechanism, servo driving mechanism or manual gear rack driving mechanism.

[0008] The utility model has the following beneficial effects: through the arrangement of semicircular arc conical jacket, when the connecting device connects pipelines of different diameters, different semicircular arc clamps can be replaced to match the connection with the pipeline, without replacing the entire clamp, saving the manufacturing cost of the clamp, at the same time, when connecting different pipelines on site, only the semicircular arc clamp needs to be carried, which is convenient for the operator to carry and replace, and the conical arrangement can make the movable clamp and the fixed clamp move in opposite directions, so that the movable clamp can be separated from the fixed clamp, avoiding the separation of the connected pipeline due to the movement of the movable clamp.
