Description

In-pipe traveling equipment

Technical Field

The invention belongs to the technical field of municipal pipeline construction machinery, and particularly relates to an in-pipe traveling device.

Background

The existing pipeline laying method is characterized in that a pre-reserved or pre-buried lead wire is adopted in advance, and then a mode of dragging the lead wire to drive the pipeline laying is adopted, but the manual laying mode has the problems of high labor intensity, high safety risk, low operation efficiency and the like. The applicant submits an invention patent named as self-balancing driving equipment in a pipe to the national intellectual property office in 2018, 7 and 2, but in the operation process of the equipment, the friction force between a spiral friction block and a pipe wall in the self-balancing driving equipment in the pipe is large, and the energy loss is large.

Disclosure of Invention

The invention provides improved self-balancing driving equipment in a pipe, aiming at the problems of the traditional pipe driving equipment.

In order to achieve the purpose, the invention is realized by adopting the following technical scheme:

the utility model provides an intraductal progression equipment, includes support and rotary mechanism, and rotary mechanism includes the spiral clutch blocks that is driven by actuating mechanism and contacts with the pipe wall, and the outside of spiral clutch blocks is provided with a plurality of bearing.

Preferably, the spiral friction block is connected with the driving mechanism through an elastic piece.

Preferably, the spiral friction block is cylindrical, spiral teeth are wound on the outer portion of the spiral friction block, and a plurality of bearings are arranged on the end face, opposite to the pipe wall, of each spiral tooth.

Further preferably, the mounting direction of the bearing coincides with the thread direction.

Preferably, the longitudinal section of each spiral friction block is in a regular triangle, a square or other regular polygons, and a plurality of bearings which are spirally distributed are arranged on the edge of each spiral friction block.

Further preferably, the bearing is externally provided with an anti-slip sleeve.

Preferably, the stent is elastic.

The invention has the beneficial effects that: according to the invention, the spiral teeth are additionally arranged outside the spiral friction block, the bearings are arranged on the spiral teeth, and the bearings on the spiral teeth reduce the rotating friction force while transmitting torque, so that the running speed of the equipment in the pipe is increased, and the energy loss is reduced.
