Technical Field

[0001] The invention relates to the technical field of automobile engine disassembly and assembly equipment, in particular to an automobile engine disassembly and assembly integrated workbench. Background Art

[0002] During the automobile maintenance process, it is often necessary to use some tools to quickly disassemble, clean, repair and replace internal parts. For example, to disassemble and repair the automobile engine, it is necessary to lift the engine from the bottom of the car, remove it, clean the surface oil stains and disassemble it, which involves a large number of disassembly tools and disassembled parts;

[0003] Traditional lifting equipment has a small work surface and can only lift the engine. It needs to be placed on the disassembly and assembly platform for a second time, and there is nowhere to put the disassembled parts and disassembly tools. When cleaning the engine or its parts, there is a lack of standardized collection of waste liquid, which often causes sewage to flow on the workshop floor, affecting the workshop environment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a comprehensive workbench for disassembly and assembly of automobile engines, which combines a movable workbench and a lifting platform to facilitate the lifting and disassembly of the engine and the placement of tools, and has an internal integrated wastewater receiving unit for receiving wastewater after cleaning to avoid contaminating the workshop floor, thereby effectively solving the problems in the background technology.

[0016] The tool back plate with plate holes is provided to facilitate placement of tools and to facilitate taking of tools when in use; when the engine needs to be lifted, the tool back plate is folded down to be lower than the work surface to prevent it from touching the vehicle chassis.

[0017] As a preferred technical solution of the present invention, a detachable automatic retractable hose reel is provided on the side of the vehicle body. By providing the automatic retractable hose reel, external air source, water source and power source are connected, and high-pressure air gun, water gun, lighting and working electricity are connected, and its pipeline line can be automatically retracted and reeled to avoid the entanglement of wire harness and pipeline, and the automatic retractable hose reel adopts a detachable design. When the vehicle body needs to be moved a long distance, the automatic retractable hose reel is removed, effectively avoiding the limitation of the displacement distance of the vehicle body by the wire harness and pipeline.

[0046] The lifting platform 2 is fixedly mounted on the vehicle body 1 at the bottom, and is provided with a lifting table 201 on the top that can be lifted vertically and pass through the through hole of the working table 107;

[0047] The lifting table 201 has an inner cavity 206 disposed therein, and a plurality of permeation holes connected to the inner cavity 206 are disposed on the upper surface. A water outlet pipe for discharging waste liquid is disposed at the lowest end of the inner cavity 206, and a valve is serially connected in the water outlet pipe.

[0048] See also Figure 2 A locker 106 capable of placing a liquid storage container is provided inside the vehicle body 1, and the valve in the water outlet pipe is a reversing valve, and the water outlet of the reversing valve is connected to different liquid storage containers in the locker 106 through a pipeline;

[0049] When the engine or its parts need to be cleaned, the cleaning liquid leaks down through the penetration holes of the lifting table 201 to the inner cavity 206 of the lifting table, and is discharged into the wastewater collection barrel through the pipe, effectively preventing the wastewater from polluting the workshop floor.

[0050] See also Figure 1 and Figure 2The vehicle body 1 is provided with multiple open storage layers 104 and closed drawers 105 to facilitate storage of disassembled parts and to classify and store different types of parts.

[0051] A push rod 102 for controlling the movement of the vehicle body 1 is fixedly arranged on the side of the vehicle body 1 , and a control switch 103 for controlling the operation of the lifting platform 2 is arranged on the grip area of ​​the push rod 102 .

[0052] See also Figure 3 A tool back plate 3 for placing tools is provided on the upper edge of the work surface 107, and the tool back plate 3 can be folded downward and hidden behind the side of the work surface 107;

[0053] The tool back plate 3 with plate holes is provided to facilitate placement of tools and to facilitate taking of tools when in use; when the engine needs to be lifted, the tool back plate 3 is folded downward to be lower than the work surface 107 to prevent it from touching the vehicle chassis.

[0054] A detachable automatic retractable hose reel 4 is provided on the side of the vehicle body 1; by providing the automatic retractable hose reel 4, external gas source, water source and power source are connected, and high-pressure air guns, water guns, lighting and working electricity are connected, and its pipeline line can automatically retract and reel to avoid entanglement of wire harnesses and pipelines, and the automatic retractable hose reel 4 adopts a detachable design. When the vehicle body 1 needs to be moved a long distance, the automatic retractable hose reel 4 is removed, which effectively avoids the limitation of the displacement distance of the vehicle body 1 by the wire harness and pipeline.

[0055] The side of the vehicle body 1 is provided with a storage slot 5 with an upper end opening, and the side wall of the storage slot 5 is provided with a hook 501 for hanging objects;

[0058] Take a scissor lift as the lifting platform 2 as an example;

[0059] When lifting and disassembling the engine, hold the push rod 102, lower the height of the lifting table 201 by controlling the switch 103, push the vehicle body 1 under the vehicle engine, and then control the lifting table 201 to rise until the engine is lifted. After disassembly, the engine is lowered along with the lifting table 201, and then the vehicle body 1 is removed, and the lifting table 201 is lowered until it reaches the height of the working table 107, and the engine is disassembled and repaired;

[0060] When the engine is flushed, the flushing water flows through the infiltration holes on the surface of the lifting table 201 and leaks into the inner cavity 206 , and then enters the water storage device in the locker 106 through the drain pipe.

[0061] When the engine oil needs to be replaced and the engine's drain port is in the lifting position of the lifting table 201, the lifting table 201 can be further lowered to allow the work surface 107 to lift the engine. The lifting table 201 is separated from the engine, and the oil replacement port leaks out, so the oil is replaced. The oil collection method is the same as the cleaning waste water collection method.

[0062] Embodiment 2:

[0063] Different from the first embodiment, a locker 106 capable of placing a liquid storage container is provided inside the vehicle body 1, and the valve in the water outlet pipe is a reversing valve, and the water outlet of the reversing valve is connected to different liquid storage containers in the locker 106 through a pipeline.

[0064] When discharging waste oil in the engine, the discharge port of the reversing valve can be changed to collect the waste oil and waste water separately; avoiding the mixing of water and oil, the waste oil can be treated separately, and the impact of waste water and waste oil on the surrounding environment can be reduced.

[0065] Embodiment three:
