A pit structure for motor vehicles

Abstract

The invention discloses a pit structure for a motor vehicle. The pit structure comprises a pit groove formed in the ground and provided with a step. The upper open end of the pit groove is provided with a layer of aluminum alloy mesh formed by arranging mutually perpendicular aluminum alloy rods in an intersecting mode. The aluminum alloy mesh is provided with an opening over the step. The grids on the aluminum alloy mesh are of a square structure. The side length of the grids is larger than or equal to 20 cm. A transparent bottom plate matched with the corresponding grid is arranged below each grid. One side edge of each bottom plate is hinged to the aluminum alloy mesh. Each bottom plate is hinged independently. An iron sheet is fixed to the upper surface of each bottom plate and located on the side edge directly facing the hinged side of the bottom plate. A magnet block matched with the iron sheet on the corresponding bottom plate is fixed to the lower surface of each grid. The pit structure is used for avoiding the condition that dirt falling from an automotive chassis falls onto the bodies of staff, and the purpose that the work environment of workers is improved is achieved.

Description

technical field [0001] The invention relates to the field of vehicle detection, in particular to a pit structure for motor vehicles. Background technique [0002] The vehicle pit is a common civil structure in the process of vehicle maintenance, testing and debugging. It is suitable for automobile production plants, repair shops, auto repair shops, etc. It is generally a square pit dug on the bottom surface, and the car is driven into the pit. , Workers enter the pit, so that the chassis of the car can be inspected, repaired and debugged conveniently, avoiding the need for workers to drill into the bottom of the car for inconvenient work, or to use jacks for maintenance. However, after the car has been driven outdoors for a long time, there will be more dirt, dust, garbage and other dirt on the chassis, which is attached to the chassis and difficult to be cleaned during the car washing process. Therefore, when workers enter the pit to overhaul the chassis, various hand tool...

AI Technical Summary

Problems solved by technology

However, after the car has been driven outdoors for a long time, there will be more dirt, dust, garbage and other dirt on the chassis. This kind of dirt is attached to the chassis and is difficult to clean during the car washing process.

Therefore, when workers enter the pit to overhaul the chassis, various hand tools are used to vibrate the car during the overhaul process, and the dirt attached to the chassis is very easy to fall, just falling on the workers who are doing work, causing work bad environment

It may even enter the workers' glasses, nostrils or mouths, affecting the normal work of the workers, and even causing the workers to inhale too much dirt, affecting the health of the respiratory tract
