Abstract

The invention discloses an MPP power cable protection pipe thread machining device. The MPP power cable protection pipe thread machining device comprises a machine frame. A fine adjustment base is welded to the outer wall of one side of the machine frame, and a gas rod is welded to the top end of the fine adjustment base. A separating plate is welded inside the fine adjustment base, a first separated cavity and a second separated cavity are formed in the two sides of the separating plate, and gas holes are connected between the first separated cavity and the second separated cavity and betweenthe second separated cavity and the gas rod. A fixed bearing pedestal is welded at the top end of the machine frame, and a sleeve penetrates through the interior of the fixed bearing pedestal. According to the MPP power cable protection pipe thread machining device, the fine adjustment base, the gas rod and a sliding groove are arranged, adjustment of an overall positioning device is achieved through mutual cooperation of the fine adjustment base and the gas rod, a fine adjustment bolt on the fine adjustment base is rotated in the adjustment process and pushes a first piston to move, and therefore the distribution state of gas located inside the first separated cavity and the second separated cavity is changed, the gas can enter the gas rod along the first separated cavity and push a second piston so as to change the position of a positioning rod.

Description

technical field [0001] The invention belongs to the technical field of MPP power cable protection pipes, and in particular relates to a thread processing device for MPP power cable protection pipes. Background technique [0002] MPP pipe, also known as MPP power cable protection pipe, is divided into excavation type and non-excavation type. MPP non-excavation pipe is also called MPP jacking pipe or tow pipe. MPP pipe uses modified polypropylene as the main raw material and has anti-corrosion properties. With the characteristics of high temperature and external pressure resistance, it is suitable for high-voltage transmission line and cable pipes below 10KV. [0003] In the Chinese patent with the patent number CN203992682U, a kind of MPP power cable protection tube thread processing device is proposed, a sleeve and a turning tool are set, and the protection tube moves and rotates relative to the sleeve during the forward movement process. Through the contact between the cut...
