Embodiment Construction

[0021] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0022] Such as Figure 1 to Figure 4 As shown, the pit safety protection device of the surface plate chain type automobile production line, the surface plate chain type automobile production line is composed of a cover plate 1 as a non-moving working area and a movable double plate chain 2 arranged on both sides of the cover plate 1 The tires on both sides of the car 3 are placed on the double-sided plate chain 2, and the double-sided plate chain 2 is controlled by the control system. When the double-sided plate chain 2 moves, it drives the car 3 to move. The car 3 is detected; the pit 4 is located in the middle of one end of the cover plate 1, and the width of the pit 4 is smaller than the distance between the tires on both sides of the car 3, so that the inspectors in the pit 4 can detect...

Abstract

The invention discloses an earth surface plate chain type automobile production line pit safety protection device. An earth surface plate chain type automobile production line consists of a cover plate and a movable double-side plate chain, wherein the cover plate is used as an unmovable working region; the movable double-side plate chain is arranged on the two sides of the cover plate; a pit is formed at a middle position at one end of the cover plate; the safety protection device is arranged on the cover plate in front of the pit and comprises a bottom plate connected with the cover plate and a pressing plate movably connected with the bottom plate; a return spring and a travel switch which can realize on and off states are arranged between the pressing plate and the bottom plate; and the travel switch is arranged on the bottom plate and is connected with a control system of the double-side plate chain. The earth surface plate chain type automobile production line pit safety protection device has the advantages of safely and effectively eliminating the potential safety hazard of the pit, along with low manufacturing and maintenance cost and high reliability.

Description

technical field [0001] The invention relates to the field of automobile safety production, in particular to a pit safety protection device for a surface plate chain type automobile production line pit. Background technique [0002] With the development and progress of automobile manufacturing technology and the pursuit of production efficiency, the production mode of "flow operation" has been adopted in the final assembly of automobiles, such as hanger hanging type, surface plate chain conveying type and other assembly line operation methods. At present, automobile companies mainly use these two methods for assembly and production. Usually, in the subsequent assembly and inspection stations of the assembly line, the assembly line uses the surface plate chain conveyor automobile production line. In this surface plate chain conveying type automobile production line assembly inspection method, the assembly / inspection personnel need to follow the vehicles on the plate chain to c...
