Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings.

[0021] The structural representation of the present invention is as shown in accompanying drawing 1, 2, and the parts of the present invention are arranged on the frame 6, and can adjust the center height position of tractor by center height lifting mechanism 16, and the traction drive system 9 of tractor is directly installed On the side plate of the crawler frame 8, each crawler belt 7 has a single driving system 9, and the driving system 9 directly drives the traction sprocket 10, and the structure is simple and compact. The sliding seats 14 at the two ends of the crawler belt 7 are fixed on two rotating discs 1, 15 front and rear, and the rotating discs 1, 15 are supported and positioned by three support bearings 2. The rotation of the front rotary disk 1 is driven by a rotary motor 5, and the power of the rotary motor 5 drives the front rotary disk 1 to rotate thr...

Abstract

The invention discloses a rotation tractor on a plastic pipe production line, comprising a traction system; the traction system comprises a traction crawler (7) which is arranged on a crawler frame (8) and a driving mechanism (9) which drives the traction crawler (7); the invention adopts two or more sets of the traction systems which are completely the same; furthermore, the rotation tractor is provided with a rotation system; each set of traction system is connected with the rotation system. By installing a plurality of traction crawlers in the invention, each crawler is independently driven by a motor, and the driving system thereof is directly arranged on the side plate of the crawler frame and directly drives a traction chain wheel, therefore the structure is compact and simple. Lifting sliding seats at two ends of the crawler frame are respectively arranged on a front rotation disc and a rear rotation disc; each rotation disc is supported and positioned by three bearings which are uniformly distributed on the circumference. The rotation tractor of the invention can be used for producing a spiral hush pipe, with an extrusion die head which has a normal structure, and fully solves the problems of material leakage and material accumulation of rotation die head.

Description

technical field [0001] The invention belongs to the field of plastic pipe production equipment, in particular to a rotary tractor on a plastic pipe production line Background technique [0002] At present, the haul-off machine on the plastic pipe extrusion production line at home and abroad generally adopts the crawler-type haul-off machine. [0003] For example, the Chinese Patent Application No. 00214981.8 is a utility model patent for a rotary tractor, which discloses a rotary tractor formed by processing a steel-plastic composite pipe or a steel pipe. The chain drive wheel, chain, bevel gear and transmission shaft connected by rotation are combined. The large sprocket drives the frame to rotate, thereby driving the pinion gear to rotate, and the pinion gear rotates around the large gear, thereby driving the traction mechanism combined on the frame to rotate. The steel-plastic composite pipe or steel pipe moves linearly on the tractor. [0004]...
