Description

Technical Field

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

[0002] At present, when using a pipeline flaw detector, a traction crawling device is indispensable. The crawling device provides power and pulls the flaw detector to travel inside the pipeline, realizing non-destructive flaw detection for each potential crack part inside the pipeline. The operation of the crawler determines the stability and reliability of the flaw detector. The existing flaw detector traction crawlers generally consist of several parts such as a housing, a drive module, a battery pack, and a control module. The housing is generally made of stainless steel plates segmented and butt-welded into a whole, and 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 significantly 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 travel inside some large pipelines, and the environment inside the pipeline is relatively complex, and there is even serious water accumulation in some places. 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 has unreasonable structural design. Content of the Utility Model

[0023] See Figures 1 to 6, the utility model is a crawler for pipeline flaw detection traction, which has a vehicle body shell 8 with a cuboid groove-shaped structure. The vehicle body shell is integrally bent and formed by a steel plate. The vehicle body shell is successively partitioned into a driving module placement cavity 22, a battery placement cavity 23, and a control module placement cavity 24. A crawler front cover 2, a battery cover plate 3, and a crawler rear cover 5 are respectively installed on the driving module placement cavity, the battery placement cavity, and the control module placement cavity. A driving module 11 is detachably installed in the driving module placement cavity through an elastic clamping plate. The driving module drives the front axle to rotate. Both ends of the front axle are outwardly equipped with front wheels 9. The front axle is mounted on both side walls of the vehicle body shell. The wheel axle of the front wheel, that is, the front axle, is clamped on the front-drive placement bayonet 21 of the vehicle body shell; a battery pack is detachably installed in the battery placement cavity through an elastic clamping plate; a control module is detachably installed in the control module placement cavity through an elastic clamping plate. Rear wheels are installed on both outer side walls of the control module placement cavity. The rear wheels are installed on the rear-drive placement bayonet 25 of the vehicle body shell; a closed wire harness box 10 is welded at the bottom of the vehicle body shell. The closed wire harness box is cuboid-shaped and arranged along the length direction of the bottom of the vehicle body shell. Cable windows 16 are respectively opened at the bottom of the driving module placement cavity and the bottom of the control module placement cavity. The cable windows are both communicated with the closed wire harness box below.

[0024] Further, in this embodiment, end plate A 14 and end plate B 19 are respectively welded seamlessly at both ends of the vehicle body shell. End plate A is arranged outside the end of the control module placement cavity. Several heat dissipation holes 15 are arranged in the middle upper part of end plate A. The heat dissipation holes are distributed in a circular ring radiation pattern; a clamping plate groove 20 is also welded and arranged on the outer side surface of end plate B. The clamping plate groove is vertically arranged from top to bottom. A head connection assembly 1 is detachably installed on the clamping plate groove. Further, a receiving antenna 6 is also arranged on the outer side wall of end plate A in the utility model.

[0025] Further, in this embodiment, a partition plate a 17 and a partition plate b 18 are welded at a certain distance in the middle of the interior of the vehicle body shell. The partition plate a and the partition plate b successively partition the interior of the vehicle body shell into a control module placement cavity 24, a battery placement cavity 23, and a driving module placement cavity 22. Further, in the utility model, the crawler front cover, the battery cover plate, and the crawler rear cover are detachably connected to the corresponding driving module placement cavity, battery placement cavity, and control module placement cavity by screws.

The above-mentioned various parts are integrated into one body. Further, a horn is also arranged in the control module placement cavity in the utility model.

[0026] As a traction crawler device for flaw detectors, the biggest feature of this utility model is that the vehicle body shell is integrally bent and formed, and the driving module, battery pack, and control module on it are all made into an integrated unit separately, which can be disassembled and assembled independently. For example, if the driving module needs to be repaired, the stepping motor, reducer, front wheel, etc. in the driving module can be disassembled together and taken for repair or replacement. The same is true for the control module. Each component in the control module can be disassembled as a whole for repair. The speed can be changed and the efficiency is higher. When the above-mentioned modules are installed, the integrated modules are directly clamped through the elastic clamping plates in each cavity. The elastic clamping plate clamping is relatively simple and stable. Coupled with the tightening of the crawler front cover, battery cover plate, crawler rear cover, etc. on each of them, the various modules inside can be well fixed. When disassembling, only the cover needs to be removed and the fastening screws need to be unscrewed to achieve the disassembly operation well.

[0027] The traction connection of each cable in the crawler can be arranged by pulling the cable from the following closed wire harness box, which has good waterproof performance and is more safe and beautiful.

[0028] The crawler in this utility model is connected to the flaw detector through the nose connection component in front of the driving module to achieve the traction and crawling function.

[0029] This utility model makes improvements to the local structure of the existing traction crawler for flaw detectors. After the improvement, the safety and stability of the entire flaw detector are improved. At the same time, the load-bearing and traction strength of the entire crawler is higher, and the use effect is better. At the same time, the integration degree of each module in this utility model is high, and each module can be disassembled and assembled conveniently, and the maintenance and replacement efficiency is high, which has good practical use and promotion value.
