Description

Profiling supporting trolley

The invention relates to a caterpillar track profiling supporting trolley capable of profiling front and back and profiling left and right, which is mainly used in a caterpillar track traveling system.

Background art:

at present, a supporting trolley in a crawler traveling system can generally realize front and back profiling, and when a crawler vehicle travels on a slope in the front and back directions, the supporting trolley can rotate by a certain angle around a shaft, so that front and back supporting wheels incline to be in better contact with a crawler. However, the crawler traveling system is mostly used in the conditions of complex and rugged terrain, and the supporting trolley can only profile forward and backward and cannot meet the use requirement of the crawler traveling system, so that the crawler is easy to wear and can also derail in severe cases.

The invention content is as follows:

in order to enable the crawler traveling system to be better suitable for the conditions of complex terrain and rugged ground, the invention provides the profiling supporting trolley which can profile forwards and backwards and can profile leftwards and rightwards.

The technical scheme adopted by the invention for solving the technical problems is as follows: the profiling supporting trolley mainly comprises a supporting wheel, a supporting wheel shaft, a supporting wheel bearing, a connecting shaft, a main supporting bearing seat, a main shaft, a main supporting bearing and the like. The main bearing block consists of an upper slip seat, a lower slip seat, a connecting bolt, a nut and the like. The main bearing block is provided with an upper bearing hole and a lower bearing hole, the central lines of the upper bearing hole and the lower bearing hole are perpendicular to each other, the upper bearing hole is positioned on the upper slip seat, and the upper slip seat and the lower slip seat are combined together to form a lower bearing hole. A main supporting bearing and a main shaft are arranged in an upper bearing hole of the main supporting bearing seat, and two ends of the main shaft extend out of the main supporting bearing seat and then are fixed on the frame body; the middle part of the connecting shaft is arranged in the lower bearing hole, and the connecting shaft can swing in the lower bearing hole. Two ends of the connecting shaft are provided with two bearing seats, a thrust wheel bearing and a thrust wheel shaft are arranged in the bearing seats, and two ends of the thrust wheel shaft are provided with thrust wheels. When the crawler belt traveling system travels on a slope with front and back inclination, the main supporting bearing seat can rotate for a certain angle around the main shaft, so that the front and back two groups of supporting wheels rotate for a certain angle along with the inclination direction of the crawler belt, and front and back profiling is realized. When the crawler traveling system travels on a slope inclined left and right, the connecting shaft can rotate for a certain angle in the lower bearing hole in the main bearing block, so that the left and right thrust wheels rotate for a certain angle along with the inclined direction of the crawler, left and right profiling is realized, the limit guide rail of the crawler is always positioned in the middle of the left and right thrust wheels, the abrasion of the thrust wheels and the track limit guide rail is greatly reduced, and the derailment phenomenon can be effectively prevented. When the crawler traveling system travels on a rugged road, the thrust wheels can simultaneously perform front and back profiling and left and right profiling according to the inclination angle of the crawler, so that the thrust wheels are always in good contact with the contact surface of the crawler.

The invention has the beneficial effects that: the profiling supporting trolley can profile back and forth and profile left and right, so that the supporting wheels can automatically profile according to the height and inclination condition of the ground, the contact surface of the track and the supporting wheels is always in good contact, the bearing capacity of the supporting wheels is improved, and the track walking system can better adapt to the rugged and muddy road conditions; meanwhile, the track limiting guide rail can be always positioned in the middle of the left and right thrust wheels, so that the abrasion between the track limiting guide rail and the thrust wheels is greatly reduced, the service lives of the track and the thrust wheels are prolonged, and the derailment phenomenon can be effectively prevented.
