Problems solved by technology

[0005] It can be seen from the above that the volume of the existing wrecker trailer is large, and it is effective when towing the illegally parked vehicle on the road, but it is difficult to tow the non-motor vehicle lane or the vehicle on the narrower section of the road. Larger, and it takes a long time to dispatch the trailer. In summary, the existing trailer is not suitable for narrow road conditions, so short-distance moving is even more difficult for large trailers

Abstract

A wheel-track-adjustable trailer frame comprises a wheel guide plate. The rear portion of the wheel guide plate is connected with a wheel stop plate, the wheel guide plate comprises two independent inclined wheel ways, a protruding connecting member is arranged on the rear portion of each inclined wheel way, multiple concave connecting members are transversely arranged on the front portion of the wheel stop plate, a first rectangular connecting hole is formed in each protruding connecting member in a hollow manner, a second rectangular connecting hole is formed in each concave connecting member in a hollow manner, and the first rectangular connecting hole and the second rectangular connecting hole are connected through a rectangular pin. Distance between the inclined wheel ways in the trailer frame can be adjusted selectively according to wheel track of different wheels to enable the trailer frame to be suitable for various models, and convenience and quickness in adjustment are realized. The wheel guide plate and the wheel stop plate are connected by adopting the rectangular pin, and transverse reinforcing can be realized, so that influence on smoothness of a trailer due to deformation after a trailer plate carries wheels is prevented.

Description

technical field [0001] The invention relates to a trailer frame capable of adjusting wheelbase and a working method thereof, belonging to the technical field of trailer tools. Background technique [0002] As the number of urban vehicles continues to increase, vehicle congestion is serious, and urban parking troubles are aggravated. In addition, people's pace of life is accelerating. Drivers are prone to temporarily park vehicles in places that are not suitable for parking due to emergencies, thus causing traffic jams and hindering the normal walking of pedestrians. Or hinder public evacuation, seriously affect people's normal life, and cause safety hazards. [0003] For this reason, in the technical field, a trailer is often used for directional removal of the vehicle, wherein the trailer is composed of a chassis, a lifting device, a lifting traction device, a hydraulic system, an electric control system, a car body and a toolbox, etc., and has the following characteristics...
