Description
Technical Field
The application relates to a large chain with double rollers and single side movement for dredging pipelines, belonging to the technical field of materials excavated by conveying or separating dredged or excavated in hydraulic engineering.
Background
In the pipeline dredging process, the conditions that the operation difficulty is high and the equipment cannot enter the underground pipeline due to the fact that the working well is too small can occur. The existing operation method mainly comprises two types of manual dredging and robot dredging:
(1) manual dredging: and pumping sewage in the pipeline after plugging the pipeline, and then manually lowering the well into the pipeline for dredging. The disadvantages of this approach are: toxic and harmful gases exist in the pipeline, so that great hidden danger is brought to the life safety of operating personnel; even if the content of toxic gas in the pipeline is low, the harm is brought to the health of operators; manual cleaning of the sludge would increase a lot of labor costs.
(2) And (3) dredging by a robot: for the robot dredging, on one hand, a mature robot which can be used for dredging large-scale pipelines does not exist in China, and most dredging robots are still in a research and development stage; on the other hand, the diameter of the working well has a great limit to the size of the robot: if the robot is too small, the crawling power is small, and the robot cannot stably crawl in the process of extracting the sludge; the robot is too big, then the robot can't get into most work wells, needs to excavate bigger work well, satisfies the construction condition.
SUMMERY OF THE UTILITY MODEL

The inner chain plate, the outer chain plate, the shaft pin, the roller and the shaft sleeve form an accommodating space, and the accommodating space can realize the arrangement of steel wire hoses with the specification of phi 120 and the like.
The upper end of each outer chain plate is of a circular arc-shaped structure, and when the two outer chain plates are spliced, only one relative movement direction exists, namely the outer chain plates can only rotate around the shaft pins in one direction, so that the whole chain mechanism cannot bend downwards and only can warp upwards to form a chain mechanism with single-side movement. When the steel wire hose is fixed in the chain mechanism, the steel wire hose is filled with silt and sewage in the working pipe, and under the action of gravity, the chain mechanism is pushed towards a fixed target direction in a linear state.
The roller is arranged on the shaft pin and positioned at two ends of the shaft pin close to the inner chain plate, and the design can balance the transmission of the power chain wheel, so that the chain link thrust balance of the double-roller single-side movable large-scale chain for pipeline dredging is ensured.
The bottom end of the outer chain plate is outwards folded, the bottom end of the inner chain plate is inwards folded, and the bottom ends of the two parts form the function of a reinforcing rib, so that the effective strength of the outer chain plate and the inner chain plate under the stress condition is ensured.

The upper end of the outer chain plate is of a circular arc-shaped structure, when the number of the links is increased along the length direction, only one relative movement direction exists in the length direction, namely the outer chain plate can only rotate around the shaft pin in one direction, so that the whole chain mechanism cannot bend downwards and can only warp upwards, and the chain mechanism forms a single-side movable structure at the moment. When the steel wire hose is fixed in the chain mechanism, the steel wire hose is filled with silt and sewage in the working pipe, and under the action of gravity, the chain mechanism is pushed towards a fixed target direction in a linear state.
A pair of rollers and a shaft sleeve are arranged on the shaft pin between each two inner chain plates, and the shaft sleeve is positioned between the pair of rollers to form a chain mechanism with a double-roller structure; every two support plates are connected through a wheel pin, rollers are installed at two ends of the wheel pin, and the rollers can be arranged on the inner sides of the support plates and also can be arranged on the outer sides of the support plates.
The design not only solves a series of problems of small operation space, difficult traveling and the like, but also can avoid potential safety hazards caused by unclear conditions in the pipeline and the existence of toxic and harmful substances in manual operation.

The rollers 21 act to contact the walls of the underground pipe in the apparatus to reduce friction. And because the pipe wall breakage phenomenon of the underground pipeline is common, the method is taken as an alternative scheme: the roller 21 should be made large in size to prevent the entire apparatus from being stopped by being caught in a damaged opening of the pipe wall during the operation traveling.
Before use, the chain mechanism 1 and the travel mechanism 2 are separated.
In use, a wire hose for a vacuum pump to be used is placed at a position intermediate between the two inner link plates 12, and an upper portion of the wire hose is directly in contact with the boss 15 and assumes a compressed state. The supporting plates 23 on the traveling mechanism 2 are respectively arranged at the bottoms of the two inner chain plates 12. Since the space between the two inner link plates 12 is slightly smaller than the outer diameter of the wire hose, the wire hose is fixed in the device.
