Multifunctional traction tray for road train

Abstract

The invention relates to the technical field of road trains, in particular to a multifunctional traction tray for a road train. Comprising a main fixing support, an inner sliding rail support, a traction disc, a sliding rail combination, a spiral lead screw combination, a ruler combination and a locking device. The main fixing support is fixedly connected to a girder of a tractor, the sliding rail combination comprises a sliding rail and a sliding block, the sliding rail is fixedly connected to the main fixing support, and the sliding block is fixedly connected to the inner sliding rail support; the spiral lead screw assembly comprises a lead screw and a nut, the nut is fixedly connected to the inner sliding rail support, and the lead screw is in threaded connection with the nut. The traction disc is fixedly connected to the inner sliding rail support, the lead screw rotates to drive the inner sliding rail support and the traction disc to move along the sliding rails, the position of the traction disc is adjusted, and the traction disc is locked through the locking device after the position is determined. The turning radius can be adjusted according to needs, multiple purposes are achieved through one vehicle, throwing and hanging, stopping and recombining are fast, and the transportation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of road trains, in particular to a multifunctional traction tray for road trains. Background technique [0002] Most of the existing road train tractors are manufactured according to the traditional design concept, which can meet people’s daily use for transporting and pulling goods. The transportation activities of road train tractors are mainly reflected in transportation activities such as transportation and dumping, and generally do not separate Remove the tractor for use. In the future, with the construction of a powerful transportation country, the transportation capacity needs to be greatly improved. It is necessary to build a dense intelligent logistics industrial park to support it, so that it will be more convenient and faster to drop, reorganize, and replace drivers every 500 to 1,000 kilometers. Solve the bottleneck problems such as insufficient road transportation capacity. [0003] But, the d...

Problems solved by technology

[0003] However, the design concept and manufacturing technology of the existing road train tractors cannot meet the basic technical requirements such as fast drop-and-hook, fast docking, and fast reorganization.

like figure 1 As shown, the radius of gyration of the existing road train is fixed, the radius of gyration of the front trailer is 3200, the radius of gyration of the tractor is 1806+1350 / 2=2481, the radius of gyration of the rear trailer is 1300, the radius of gyration of the tractor conforms to that of the front The radius of gyration of the trailer. When the tractor is dropped, it is planned to tow the rear trailer. The radius of gyration of the rear trailer is too short to be able to hook up, let alone drive.

Traditional design and manufacture lead to: fixed turning radius, unable to tow trailers with different turning radius
