Abstract

The invention discloses a limiting structure used for the inner part of a main body pipeline transportation device of a tube push bench. The limiting structure comprises a circular chassis, connectingplates, a vertical rod and side plates, wherein the periphery of the chassis is uniformly connected with three groups of connecting plates; the middle end of the top of the chassis is connected withthe vertical rod which is longitudinally arranged through a through hole; a plurality of telescopic poles which are longitudinally arranged are uniformly connected between the top of a sleeve ring andthe bottom of a baffle plate; the top of the chassis is uniformly connected with three groups of circular-arc-shaped side plates; and positions, between a roller and the side plates, at the two sidesoutside a mounting plate are transversely connected with positioning rods. The limiting structure is suitable for different working needs, and can be suitable for main body pipelines of different dimensions of the tube push bench, so that the pipelines can be limited by the side plates outside the three side plates; and in use, the main body pipelines are not liable to shake, so that the stable performances are good. Moreover, the main body pipelines can be longitudinally placed and transported, so that the main body pipelines are prevented from rolling in transportation, and therefore, the condition that risk is caused as the main body pipelines drop from the transportation device is avoided.

Description

technical field

[0001] The invention relates to a position-limiting structure, in particular to a position-limiting structure used inside a pipeline transportation device of a main body of a pipe jacking machine. Background technique

[0002] The pipe jacking machine is a kind of construction machinery specially designed for rock tunnels. It is suitable for various weathered rock soil conditions, and has been more and more widely used in rock tunnel projects such as railways, electric power, water conservancy, coal, mining, transportation, urban underground engineering machines, and subways. Pipe jacking machine is an important equipment for rock tunnel construction. It is mainly used for cutting rock, breaking rock and transporting the broken rock to complete the construction of rock tunnel. The main devices inside the pipe jacking machine are installed inside the hollow main pipeline, and the main pipeline often requires specific devices for transportation.
