DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides Figure 1-Figure 7 A pit structure for automobile chassis inspection and debugging is shown, including a target ground 1, a pit body 2 is opened on the target ground 1, a staircase component 4 for workers to enter and exit is installed on one side wall of the pit body 2, a workbench 6 is slidably provided on the inner bottom surface of the pit body 2, and the workbench 6 has flanges around it. A plurality of mounting grooves 25 are opened on the bottom surface of the pit body 2, and a hydraulic cylinder 63 is fixedly installed inside the mounting groove 25. A reinforcing rib 61 is fixedly installed on the lower surface of the workbench 6, and a plurality of evenly distributed lifting claws 62 are fixedly installed on the side of the reinforcing rib 61 close to the staircase component 4, and the lifting end of the hydraulic cylinder 63 is fixedly installed on the lower surface of the workbench 6.

[0032] In actual use, the car is first driven to the top of the pit body 2, and then the workers enter the interior of the pit body 2 through the staircase component 4. The workers inspect and debug the chassis of the car above the workbench 6. If oil leakage or fuel leakage occurs during the inspection and debugging process, the liquid will directly fall on the surface of the workbench 6. Because the workbench 6 has flanges on all sides, the liquid will be blocked on the upper surface of the workbench 6 and will not flow everywhere. The workbench 6 is made of stainless steel to prevent the interior of the pit body 2 from being contaminated, and the inner wall of the pit body 2 is almost all made of cement. When liquid dirt falls into it, it will be absorbed by the cement wall, and then it cannot be completely cleaned up in the later cleaning, resulting in harmful gases. The gas will continue to evaporate and accumulate inside the pit body 2 for a long time, while impurities such as engine oil and fuel will evaporate harmful gases. Working for a long time in this environment will cause great harm to the workers' bodies. The stainless steel material can prevent liquid penetration and can quickly clean up the impurities during cleaning to prevent gas accumulation caused by long-term volatilization, thereby ensuring the safety of the workers. After the work is completed, the hydraulic cylinder 63 is started to push the workbench 6 out of the pit body 2, and then the workbench 6 is cleaned without entering the pit body 2, so that the water generated by cleaning can be easier to clean up, preventing the pit body 2 from being soaked in water and causing damage, and it is lifted to be flush with the target ground 1 to make the cleaning space wider and the cleaning more thorough.

[0033] The stair component 4 includes a plurality of step treads 41, and support blocks 42 are provided under both ends of the step treads 41. The step treads 41 are slidably clamped inside the pit body 2, and the support blocks 42 are fixedly installed on the two side walls of the pit body 2. A plurality of evenly distributed blocking rods 43 are fixedly installed on one side of the lower surface of the step treads 41, and a plurality of evenly distributed support plates 44 are fixedly installed on the side of the lower surface of the step treads 41 away from the blocking rods 43, and the plurality of blocking rods 43 and the plurality of support plates 44 are staggered.

[0034] When the hydraulic cylinder 63 works to drive the workbench 6 and the reinforcing ribs 61 to rise, the lifting claw 62 will lift one of the step pedals 41, and when the step pedal 41 is lifted, the support plate 44 will also be driven to rise, and then the support plate 44 will lift the adjacent step pedal 41, and this reciprocating process will continue until all the step pedals 41 are flush with the target ground 1. When the hydraulic cylinder 63 is powered off, it will reset, and the workbench 6 and the reinforcing ribs 61 will descend, causing multiple step pedals 41 to descend, and the step pedals 41 will descend to the surface of the support block 42 and be supported by the support block 42. At this time, multiple step pedals 41 are combined to form a step. The barrier rod 43 can prevent the workers' feet from being stuck by the step pedals 41 when they move upwards, and can also enable the stair component 4 to have ventilation capabilities.

[0035] When no debugging and maintenance work is required, the hydraulic cylinder 63 is in working condition, lifting the workbench 6 and multiple step pedals 41 and making them flush with the target ground 1, completely blocking the opening position of the pit main body 2, and ensuring the sealing inside the pit main body 2 when not working, preventing debris from falling into the pit main body 2, and preventing people from falling, ensuring the safety of the pit main body 2 when not in use. This structure enables the pit main body 2 to have multiple functions. It can be used as a maintenance pit when working, and can be used as an ordinary ground when not working.

[0036] A fan 5 is fixedly installed on one side of the pit body 2 close to the staircase component 4, an air flow channel 24 is opened at a position corresponding to the target ground 1 and the fan 5, and the air flow channel 24 is L-shaped. A mesh plate 26 is fixedly installed on the end of the air flow channel 24 away from the fan 5, and two pressure plates 11 are fixedly installed on the upper surface of the target ground 1. The two pressure plates 11 are respectively located on both sides of the pit body 2

[0037] The pressure plate 11, the lighting component 3, and the fan 5 are connected in series to form a first circuit, and the hydraulic cylinder 63 is connected in parallel at both ends of the pressure plate 11 to form a second circuit. The second circuit is connected in series with a switch K1 and a resistor R1. When a vehicle stops on the pressure plate 11, the pressure plate 11 is triggered and is in a connected state. At this time, the first circuit is in a connected state. When the pressure plate 11 is in a connected state, it can be regarded as a section of wire, and its internal resistance is small and can be ignored. The hydraulic cylinder 63 and R1 in the second circuit are connected in series, so that the resistance of the second circuit is large. According to the virtual disconnection principle, it can be known that the second circuit can be regarded as an open circuit state at this time, so the hydraulic cylinder 63 does not work. When the pressure plate 11 is disconnected, the current passes through the second circuit. At this time, the control switch K1 is turned on to control the hydraulic cylinder 63 to work, so that when there is a car, whether the switch K1 is turned on or off, the hydraulic cylinder 63 cannot be started. Only when there is no vehicle above can the hydraulic cylinder 63 be controlled by K1 to work, so as to prevent the switch K1 from being accidentally touched during work, causing the hydraulic cylinder 63 to work and drive the workbench 6 to rise and cause damage to the staff above, thereby ensuring the safety of the device when in use.

[0038] When the vehicle stops on the pressure plate 11, the first circuit is in a pass state, so that the lighting component 3 and the fan 5 both work. The lighting component 3 illuminates the chassis of the car, so that the workers can see more clearly and debug and inspect more carefully. At the same time, the fan 5 will work. The fan 5 absorbs external air through the air flow channel 24 and drives the gas to pass through the stair component 4 and blow into the interior of the pit body 2, driving the gas flow, so that the air circulation inside the pit body 2 is better, so that the working environment of the workers is optimized, and the harm to the workers by harmful gases is reduced. The external air can also be blown into the interior of the pit body 2 to ensure that the interior of the pit body 2 is cool.

[0039] A plurality of wiring grooves 22 are provided at the upper end of the side wall of the target ground 1, and a lighting component 3 is installed inside the wiring groove 22. The lighting component 3 includes a spherical ring 31, and the spherical ring 31 is fixedly installed inside the wiring groove 22. A spherical center piece 32 is connected to the middle of the spherical ring 31 through a ball and socket structure, and a lighting lamp 33 is fixedly installed in the middle of the spherical center piece 32.

[0040] When in use, the lighting direction of the lighting lamp 33 can be adjusted by pressing the spherical center piece 32, so that the light emitted by the lighting lamp 33 can be accurately hit at a suitable position, which is more convenient for work.

[0041] A water blocking edge 12 is fixedly installed on the target ground 1 , and the pit body 2 is located in the middle of the water blocking edge 12 . The water blocking edge 12 can prevent external liquid from invading the interior of the pit body 2 , thereby ensuring the cleanliness of the interior of the pit body 2 .

[0042] A plurality of evenly distributed first storage compartments 21 and second storage compartments 23 are provided on the inner side wall of the target ground 1. The first storage compartments 21 and second storage compartments 23 can be used to store workers' tools without repeatedly moving the tools, thereby reducing workload.

[0043] Working principle: first drive the car to the top of the pit body 2, then the workers enter the interior of the pit body 2 through the staircase component 4, and the workers inspect and debug the chassis of the car above the workbench 6. If there is oil leakage or fuel leakage during the inspection and debugging process, the liquid will directly fall on the surface of the workbench 6. Because the workbench 6 has flanges around it, the liquid will be blocked on the upper surface of the workbench 6 and will not flow everywhere. The workbench 6 is made of stainless steel to prevent the interior of the pit body 2 from being contaminated. After the work is completed, start the hydraulic cylinder 63 to push the workbench 6 out of the pit body 2, and then clean the workbench 6 without entering the interior of the pit body 2;

[0044] When the hydraulic cylinder 63 works to drive the workbench 6 and the reinforcing ribs 61 to rise, the lifting claw 62 will lift one of the step pedals 41, and when the step pedal 41 is lifted, the support plate 44 will also be driven to rise, and then the support plate 44 will lift the adjacent step pedal 41, and this reciprocating process will continue until all the step pedals 41 are flush with the target ground 1. When the hydraulic cylinder 63 is powered off, it will reset, and the workbench 6 and the reinforcing ribs 61 will descend, causing multiple step pedals 41 to descend, and the step pedals 41 will descend to the surface of the support block 42 and be supported by the support block 42. At this time, multiple step pedals 41 are combined to form a step. The barrier rod 43 can prevent the worker's feet from being stuck by the step pedal 41 when moving upward, and can also make the stair component 4 have ventilation capabilities.

[0045] The pressure plate 11, the lighting component 3, and the fan 5 are connected in series to form a first circuit, and the hydraulic cylinder 63 is connected in parallel at both ends of the pressure plate 11 to form a second circuit. The second circuit is connected in series with a switch K1 and a resistor R1. When a vehicle stops on the pressure plate 11, the pressure plate 11 is triggered and is in a connected state. At this time, the first circuit is in a connected state. When the pressure plate 11 is in a connected state, it can be regarded as a section of wire, and its internal resistance is small and can be ignored. The hydraulic cylinder 63 and R1 in the second circuit are connected in series, so that the resistance of the second circuit is large. According to the virtual disconnection principle, it can be known that the second circuit can be regarded as an open circuit state at this time, so the hydraulic cylinder 63 does not work. When the pressure plate 11 is disconnected, the current passes through the second circuit. At this time, the control switch K1 is turned on to control the hydraulic cylinder 63 to work, so that when there is a car, the device cannot start the hydraulic cylinder 63 regardless of whether the switch K1 is turned on or off. Only when there is no vehicle above can the hydraulic cylinder 63 be controlled by K1 to work;

[0046] When the vehicle stops on the pressure plate 11, the first circuit is in a connected state, so that the lighting component 3 and the fan 5 both work. The lighting component 3 works to illuminate the chassis of the car, and the lighting direction of the lighting lamp 33 is adjusted by pressing the spherical center piece 32, so that the light emitted by the lighting lamp 33 can be correctly hit at the appropriate position.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
