Telescoping long stroke automatic guiding transport cart

Abstract

The invention relates to a telescoping long stroke automatic guiding transport cart, and belongs to the technical field of automobile assembling. The cart comprises a front frame and a rear tail frame; the front frame and the rear tail frame are connected through a telescopic transmission device, one end of the telescopic transmission device is in supporting connection with the front frame, and the other end of the telescopic transmission device is connected with the rear tail frame; a steering wheel and supporting universal wheels are symmetrically arranged at the bottom of the front end of the front frame, and a supporting direct movement power wheel is arranged in the middle of the rear end, and the supporting universal wheels are arranged on the two sides of the rear end of the rear tail frame. By arranging the simple and mechanical floating structure, the ground flatness of the AGV travelling region can be lowered, the strength and rigidity of a telescoping guiding pair structureare lowered, the civil engineering construction and AGV manufacturing cost is low, and the bending radius is small.

Description

technical field [0001] The invention relates to the technical field of automobile assembly, in particular to a retractable long-distance automatic guided transport vehicle. It is used in assembly AGV (automatic guided vehicle) assembly and conveying production line, combined with special assembly fixtures, especially suitable for long frame beams and other components in large frames. Background technique [0002] The existing telescopic AGV usually has two structural forms, the base fixed type and the base telescopic type: the base fixed AGV, the front and rear support fixtures are retractable, the telescopic motor is fixed in the middle, the driving gear rotates and meshes with the left and right rack gears, and the linear guide rail is horizontal The guide pair drives the left and right racks to move towards each other, and drives the front and rear support clamps to expand and contract. Due to the fixed AGV base, the AGV base has a large telescopic direction, a large tur...

Problems solved by technology

This structure has the following defects: elongation is unidirectional, and the blocking piece slides on the blocking strip. When the position is determined, the blocking piece is stuck on the blocking strip. If a compressive force is applied, because the blocking piece is stuck on the blocking strip, Whether it can be compressed or not, the ratchet pawl structure of the blocking strip and the blocking member realizes the effect of only one-way stretching. When shortening the trailer, an external force needs to be applied to shrink it. On the other hand, when it is stretched to a relatively When the length is large, there is no supporting structure in the middle, and the middle section of the whole device is suspended, which affects the overall stability
