Gravity type automatic back-and-forth transport vehicle

Abstract

The invention discloses a gravity type automatic back-and-forth transport vehicle, which comprises a transport vehicle body, wherein the transport vehicle body comprises a frame, a bearing part used for bearing a workpiece, travelling wheels arranged at the bottom of the frame, a reset assembly and a transmission part used for enabling the frame to move forwards or backwards, wherein the transmission part is used for converting gravity borne by the bearing part into power and transmitting the power to a wheel shaft, the wheel shaft rotates to enable the frame to move forwards, the transmissionpart is further used for converting elastic force borne by the bearing part into power and transmitting the power to the wheel shaft, and the wheel shaft rotates in the opposite direction to enable the frame to move backwards to the initial position. The transport vehicle has the advantages that an external power source is not needed, automatic reciprocating of the transport vehicle body is achieved through the gravity of workpieces and the elastic force of reset constant-force springs, the structure is ingenious, the external power source is not needed, low carbon and environmental protection are achieved, the cost is only 6%-10% of that of an existing AGV, the investment cost is reduced, and the transport vehicle is economical and practical.

Description

technical field [0001] The invention relates to a transport vehicle in an automobile production line, in particular to a gravity type self-reciprocating transport vehicle. Background technique [0002] In the automobile assembly line, it often involves the transfer of heavy parts between two stations. In the production process, in order to meet the walking needs of workers, two adjacent stations are usually set at intervals, so it is impossible to use fixed slides to transfer heavier parts. The traditional method of transferring heavy parts between different stations is usually manual handling, which has high labor intensity, long working hours and low work efficiency. For this reason, the existing production line usually uses fully automatic transport vehicles (ie AGV) to transfer parts, and the price of each AGV is as high as 60,000 to 100,000 yuan, which is relatively expensive and the investment cost is high.
