Problems solved by technology

[0004] The inventors of the present disclosure found that (1) the current method of hoisting the round pipes is used to assemble the two round pipes in the tunnel, which is complicated to operate, and it is not easy to operate when fixing the two round pipes, which delays the progress of the project; (2) the existing The circular tube connectors generally use a whole piece of material, which is cumbersome and has the problem of waste of materials; (3) the existing circular tube track connectors have high cost, many accessories, and cumbersome installation procedures. The advantages cannot be shown, which leads to the failure of effective promotion and application of the circular tube track

Embodiment 1

[0040] Such as figure 1 As shown, Embodiment 1 of the present disclosure provides an expansion type quick connector for a circular tube track, which includes a cylindrical connector body 3, which is similar to a section of a circular tube, and its outer diameter and the inner diameter of the round pipe 11. The top of the connector body 3 is a hoisting wire drum 1, which is used to connect with the hoisting bolt 13 hanging down from the top of the tunnel to realize hoisting.

[0041] The lower part of the lifting wire drum 1 is a first connecting piece 2 for connecting the lifting wire drum 1 and the connecting piece body 3 .

[0042] Such as image 3 As shown in the side view, the first connecting piece 2 described in this embodiment is narrower than the hoisting wire drum 1, which is convenient for the walking mechanism of the circular rail robot to pass through the connecting piece.

[0043] Such as Figure 6 As shown, the connecting piece connects the round pipe 11 into ...

Embodiment 2

[0050] Embodiment 2 of the present disclosure provides a round pipe, which is matched with the expansion type quick connector for the round pipe track described in Embodiment 1 of the present disclosure, including a round pipe body, the upper part of the round pipe body is close to the end There is a third opening corresponding to the counterbore, and the end of the round pipe body is provided with a gap corresponding to the first connecting piece.

Embodiment 3

[0052] Embodiment 3 of the present disclosure provides a working method for an expansion-type quick connector for a circular pipe track, using the expansion-type quick connector for a circular pipe track described in Embodiment 1 of the present disclosure and Embodiment 2 of the present disclosure The circular tube, the steps are as follows:

[0053] Set two round pipes on the two ends of the connector body of the connector respectively, the third opening on the round pipe body is coaxially aligned with the counterbore, and the bolt is screwed into the connector body from the third opening;

[0054] The bottom of the bolt reaches the crater structure, continue to be tightened, the bolt squeezes the deformed part, the deformed part moves downward slightly, and the connecting piece body expands and tightens inside the round pipe body;

[0055] After the bolt is fully tightened, the head of the bolt is stuck in the third opening of the round pipe to complete the connection of the...

Abstract

The invention provides an expansion type rapid connecting piece for circular tube tracks, circular tubes and a working method. The expansion type rapid connecting piece for the circular tube tracks comprises a cylindrical connecting piece body, an external diameter of the connecting piece body is in clearance fit with internal diameters of the circular tubes, at least one counter bore is correspondingly formed in the positions, close to the two ends, of the top of the connecting piece body, wire sleeves coaxial with the counter bores are arranged at the top of the inner side of the connectingpiece body, and a bolt fixing structure arranged opposite to the wire sleeves is arranged at the bottom of the inner side of the connecting piece body; gaps extending to the inside from the end partsare correspondingly formed in the two sides of the bottoms of the two ends of the connecting piece body, transformation parts are correspondingly formed at the bottoms of the two ends of the connecting piece body, and the bolt fixing structure is arranged on the transformation parts; and when the two circular tube tracks are connected, expansion force generated from the interiors of the two circular tube tracks connects and fastens the two circular tubes, operation construction in a tunnel is greatly convenient for construction personnel, and the reliability of the circular tube tracks after connection is high.

Description

technical field [0001] The present disclosure relates to the technical field of circular tube tracks, and in particular to an expansion type quick connector for a circular tube track, a circular tube and a working method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Rail robots have been widely used in many fields, such as outdoors or tunnel corridors, where they can perform functions such as inspection and fire protection. The circular tube-shaped robot running track is used in the tunnel inspection robot system because of its low cost and easy installation. Now, connecting pieces are often used to connect and hang the circular tubes, which can be directly used as a track. [0004] The inventors of the present disclosure found that (1) the current method of hoisting the round pipes is used to assemble the two round pipes in the tunn...
