Bellows universal tractor

Abstract

The invention relates to the field of pipe production, in particular to a universal traction machine for corrugated pipes. The traction machine comprises a support. A transferring box is arranged on the support. Multiple driving mechanisms are mounted in the transferring box. The traction machine is mainly characterized in that the traction machine further comprises an air inflation machine; each driving mechanism comprises a driving wheel, a driving motor and a driving shaft; each driving motor drives the corresponding driving wheel to rotate; each driving wheel comprises two round support plates; an air bag layer is connected between the outer edges of every two round support plates; each driving shaft is hollow, one end of each driving shaft penetrates one of the corresponding round support plates and is fixedly connected with the other round support plate, and multiple air holes are formed in the positions, between the corresponding two round support plates, of each driving shaft; the other end of each driving shaft is connected with a breather pipe in a rotary manner; and each breather pipe communicates with the air inflation machine. According to the universal traction machine, air inflation is conducted on the driving wheels, so that the air bag layers are made to expand outwards, corresponding sawteeth are formed by the air bag layers and the appearance of the corrugated pipes of various specifications, and the corrugated pipes can be transferred; and the universal traction machine can be wider in application scope.

Description

technical field [0001] The invention relates to the field of pipe production, in particular to a general tractor for corrugated pipes. Background technique [0002] At present, domestic pipe haulers generally adopt crawler-type haulers, which are divided into upper and lower crawlers, and the rotation of each crawler is driven by a motor. However, for some pipes with special shapes, such as corrugated pipes or other pipes with uneven surfaces, if the crawler tractor is used to pull them, the surface of the pipes may be scratched or damaged. The structure will make the contact area between the crawler tractor and the pipe smaller, and it is easy to slip during transmission, which will affect the quality of the pipe. [0003] The Chinese patent with the notification number CN201419508 discloses a traction mechanism for plastic bellows, which includes a bracket, a plastic bellows forming mold is installed on the upper end of the bracket, and a short cylindrical support wheel s...

Problems solved by technology

Although this traction mechanism effectively solves the problem of bellows traction, when pulling bellows of different specifications, it is necessary to replace the corresponding inserts, which makes the operation more cumbersome
