Description

Technical Field

[0001] The utility model relates to the technical field of flaw detector power equipment, in particular to a traction crawler housing. Background Art

[0002] At present, when using a pipeline flaw detector, a traction crawling device is indispensable. The crawling device provides power to pull the flaw detector through the pipeline to achieve non-destructive flaw detection of each potential crack site inside the pipeline. The operation of the crawler determines the stability and reliability of the flaw detector. The existing flaw detector traction crawler generally consists of a housing, a drive module, a battery pack and a control module. The housing is generally made of stainless steel plates, which are segmented and butt-welded into a whole. Each segment above corresponds to the placement of the drive module, the battery pack and the control module. The bearing strength of this housing structure is obviously insufficient, and there is a risk of fracture after long-term use. The connection parts of each module on the housing are connected and transmitted through wire harnesses. Most of these connected wire harnesses are directly fixed on the side wall of the housing. However, the housing of the crawler often has to walk in some large pipelines, and the environment inside the pipelines is relatively complex, and some places are even seriously waterlogged. Therefore, the current crawler housing often has to travel in water, which obviously poses a safety hazard to the safe use of the wire harnesses. The current housing structure is unreasonable in structural design. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a traction crawler housing aiming at the above situation. The crawler housing adopts a new structural design, with higher overall strength and higher use safety.

[0004] The specific scheme of the utility model is: a traction crawler housing, having a vehicle body housing with a cuboid trough-shaped structure. The vehicle body housing is integrally bent and formed by a steel plate. At both ends of the vehicle body housing, an end plate A and an end plate B are respectively welded. Inside the vehicle body housing, a partition plate a and a partition plate b are welded at a certain distance. The partition plate a and the partition plate b sequentially divide the vehicle body housing into a drive module placement cavity, a battery placement cavity and a control module placement cavity. A closed wire harness box is welded at the bottom of the vehicle body housing. The closed wire harness box is cuboid-shaped and arranged along the length direction of the bottom of the vehicle body housing. A cable window is opened at the bottom of the drive module placement cavity and the bottom of the control module placement cavity respectively. The cable windows are both communicated with the closed wire harness box below.

[0005] Furthermore, in the utility model, the end plate A, the end plate B, the partition plate a and the partition plate b have the same shape, and their horizontal heights are kept consistent.

[0006] Further, in the present utility model, the end plate A is arranged at the side of the control module placement cavity, and several heat dissipation holes are arranged at the middle and upper part of the end plate A.

[0010] Further, in the present utility model, front-drive placement bayonets are provided at symmetric positions on both side walls of the drive module placement cavity; rear-drive placement bayonets are provided at symmetric positions on both side walls of the control module placement cavity.

[0011] Further, in the present utility model, several screw holes are provided on the plate surfaces of the end plate A and the end plate B; several screw holes are provided at the top and side of the partition plate a and the partition plate b.

[0012] The present utility model reforms and designs the existing traction crawler shell.
