[0038] Depend on Figure 1 - Fig.11 It is given that in order to achieve the purpose of reducing fire hazards, the present invention includes:

[0043] It should be noted that the air inlet end of the dynamic pressure chamber 2 is connected to a filtering device, and the dynamic pressure chamber 2 is blown and pressurized by an industrial fan. A flow equalizer is provided between the dynamic pressure chamber 2 and the static pressure chamber 3, which can make the airflow distribution in the static pressure chamber 3 more uniform. A non-woven filter layer is laid at the bottom of the static pressure chamber 3, and the wind will be more uniform when it flows downward through the non-woven filter layer; the thermal camera 4 is a prior art and will not be described in detail here. It is located in the middle of the lower side of the static pressure chamber 3 and can continuously detect the lower side of the chamber body 1; the air supply system is an industrial air conditioner, which is used to adjust the internal temperature of the chamber body 1. It is a prior art and will not be described in detail here. It is located on the upper side of the dynamic pressure chamber 2; the front and rear sides of the chamber body 1 are each rotatably connected to two chamber doors;

[0044] When in use, the bus to be processed can be parked in the chamber 1, and then the bus can be processed in multiple steps through the longitudinal platform 6 and the transverse platform 7 of the three-dimensional lifting platform, including: frame correction section, frame primer section, body putty section, body primer section, etc., which increases the practicability of the equipment for bus processing. In different processing sections, the air supply system can adjust the temperature inside the chamber 1 so that the temperature inside the chamber 1 meets the processing and staff requirements. The exhaust gas treatment system is used to treat paint mist-containing air to meet environmental protection requirements. Staff can perform high-altitude operations through the transverse platform 7, which is convenient for operation.

[0045] Further, by Figure 5 - Fig. 9 It is given that, in order to facilitate the staff to work at high places of the bus, a plurality of power boxes 9 are fixedly connected to the lower side of each of the longitudinal platforms 6, and each of the power boxes 9 is slidably connected to two support columns 10, and the upper and lower sides of each of the support columns 10 are fixedly connected to the chamber body 1, and a first rack 11 is fixedly connected to one side of each of the support columns 10 close to the side wall of the chamber body 1, and each rack is meshed with a first gear 12, and each first gear 12 is rotatably connected to the corresponding power box 9, and the first gear 12 cooperates with the first rack 11 to form a structure in which the longitudinal platform 6 can be raised and lowered;

[0046] When in use, when the first gear 12 rotates, the power box 9 drives the longitudinal platform 6 to rise and fall, and then drives the staff located on the transverse platform 7 to move in height, so as to facilitate operations at high places of the bus.

[0047] Further, by Figure 5 - Fig. 9 In order to make the height adjustment more stable, the lower side of each longitudinal platform 6 is rotatably connected to two first transmission shafts 13, each first gear 12 is fixedly connected to the corresponding first transmission shaft 13, and the middle part of each first transmission shaft 13 is fixedly connected to a driven sprocket 14. A first motor 15 fixedly connected to the corresponding power box 9 is provided on the lower side of the longitudinal platform 6, and a driving sprocket 16 is fixedly connected to the output end of the first motor 15. The driving sprocket 16 and the outer sides of the two driven sprockets 14 are matched with a chain 17;

[0048] It should be noted that the first motor 15 is a servo motor, which will not be described in detail here;

[0049] When in use, when the first motor 15 rotates, the two driven sprockets 14 are driven to rotate through the driving sprocket 16 and the chain 17, and then each first gear 12 is driven to rotate through the first transmission shaft 13 to adjust the height of the longitudinal platform 6.

[0050] Further, by Figure 5 - Fig. 9 It is given that, in order to protect the staff in the state of sudden power failure, a rotary damper 18 is fixedly connected to the rear side of the driving sprocket 16, and the fixed end of the rotary damper 18 is fixedly connected to the corresponding power box 9;

[0051] During use, when a sudden power outage occurs, under the action of the rotary damper 18, the rotation speed of the active sprocket 16 will not be too fast, and the speed at which the longitudinal platform 6 descends under the action of gravity will not be too fast, which can protect the staff.

[0052] Further, by Figure 5 - Fig. 9 It is given that, in order to facilitate operations at different positions of the bus, each of the horizontal platforms 7 is fixedly connected to a support seat 19 on the lower side, and each of the longitudinal platforms 6 is provided with two support grooves 20 adapted to the support seat 19 in the middle, and each of the support grooves 20 is fixedly connected to a second rack 21 on the lower side, and each of the second racks 21 is meshed with a second gear 22 on the lower side, and each of the second gears 22 is fixedly connected to a second motor 23, and the second gears 22 and the second racks 21 cooperate with each other to form a structure in which the horizontal platform 7 can move left and right;

[0053] It should be noted that the second motor 23 is a servo motor, which is a prior art and will not be described in detail here;

[0054] During use, when the second motor 23 is started, the corresponding second gear 22 will drive the support seat 19 to move forward and backward, thereby enabling the transverse platform 7 to move forward and backward to perform operations on different positions of the bus.

[0055] Further, by Figure 5 - Fig. 9 In order to enable multiple workers to cooperate with each other in bus operations, each of the transverse platforms 7 is fixedly connected to a first guardrail 24 on the upper side, each of the first guardrails 24 is provided with an entrance, and each of the first guardrails 24 is rotatably connected to a guard door 25 at a position corresponding to the entrance, and the two entrances on the upper side of each of the longitudinal platforms 6 can be connected to each other;

[0056] When in use, when the staff is performing normal operations on the bus, they can stand on the transverse platform 7. At this time, the first guardrail 24 and the protective door 25 can protect the staff when working at height. When the staff needs to move too far on the transverse platform 7, or needs to work together with the staff on another transverse platform 7, the two transverse platforms 7 can be brought close to each other. At this time, the protective door 25 is opened, and the staff can move between the two transverse platforms 7, which is convenient for the staff to work flexibly.

[0057] Further, by Figure 5 - Fig. 9 It is given that in order to increase the fire safety performance of the painting operation, the fire-fighting mechanism 8 includes a fire-fighting box 26 fixedly connected to the horizontal platform 7, one end of the fire-fighting box 26 is rotatably connected to a box door 27, two replaceable fire-fighting gas cylinders 28 are arranged inside the fire-fighting box 26, and the fire-fighting gas cylinders 28 are carbon dioxide fire extinguishers filled with carbon dioxide liquid. A first channel 29 is opened inside the fire-fighting box 26, and a solenoid valve 30 is arranged in the middle of the first channel 29. A second channel 31 is opened inside the horizontal platform 7, and the first channel 29 and the second channel 31 are connected to each other. A plurality of jet holes 32 are opened at one end of the second channel 31 away from the first channel 29, and a nozzle 33 is fixedly connected inside each jet hole 32;

[0058] During use, when the thermal camera 4 detects that the temperature is higher than the preset value, it will open the solenoid valve 30 through an electrical signal. At this time, the carbon dioxide liquid in the fire cylinder 28 will be gasified and pass through the first channel 29, the solenoid valve 30, the second channel 31 and the jet hole 32 in sequence, and be sprayed out through the nozzle 33, thereby extinguishing the abnormally high temperature in the chamber body 1.

[0059] Further, by Figure 5 - Fig.10 It is given that, in order to reduce the influence of frost formed on the nozzle 33 on the gas ejection speed when the liquid carbon dioxide is gasified, a pneumatic turntable 34 is rotatably connected inside the second channel 31, and a plurality of power blades 35 are fixedly connected to the outer side of the pneumatic turntable 34, and a power turntable 36 is fixedly connected to the lower side of the pneumatic turntable 34, and a first swing rod 37 rotatably connected to the horizontal platform 7 is provided on the lower side of the power turntable 36, and a sliding groove 38 is provided in the middle of the first swing rod 37, and a sliding block 39 is fixedly connected to the lower side of the power turntable 36, and the sliding block 39 is slidably connected to the sliding groove 38, and a second swing rod 40 is slidably connected to the side of the first swing rod 37 away from the longitudinal platform 6 through a sliding key, and a defrost rack 41 is rotatably connected to the side of the second swing rod 40 away from the first swing rod 37;

[0060] During use, when carbon dioxide enters the jet hole 32 through the second channel 31, the pneumatic turntable 34 will be driven to rotate through the power blades 35, and then the power turntable 36 will be driven to rotate unidirectionally. At this time, the sliding block 39 will slide in the sliding groove 38, and then the first swing rod 37 will swing back and forth, and the second swing rod 40 will also move back and forth. When the second swing rod 40 moves back and forth, it will drive the defrost rack 41 to move back and forth relative to the horizontal platform 7, so as to defrost each nozzle 33.

[0061] Further, by Fig.11 It is provided that, in order to be able to perform defrosting and automatically adjust the fire extinguishing direction, a defrost brush 42 is fixedly connected to each of the front and rear sides of the defrost rack 41, and an air guide port 43 is provided on the side of the defrost rack 41 away from the horizontal platform 7, and a plurality of air guide plates 44 are rotatably connected to the inner side of the air guide port 43, and an air guide rod 45 movable up and down is provided in the middle of the defrost rack 41, and the middle part of each of the air guide rods 45 is rotatably connected to the air guide plate 44, and an air guide slider 46 is fixedly connected to the lower side of the air guide rod 45, and an air guide protrusion 47 is fixedly connected to the end of the second swing rod 40 away from the first swing rod 37, and the air guide slider 46 is slidably connected to the air guide protrusion 47;

[0062] When in use, when the defrost rack 41 moves back and forth with the second swing rod 40, the nozzle 33 will be defrosted by the defrost brush 42, and when the defrost rack 41 moves back and forth, the defrost rack 41 will rotate relative to the second swing rod 40. Since the air guide rod 45 can only move up and down along the defrost rack 41, the air guide protrusion 47 is fixedly connected to the second swing rod 40, that is, the air guide slider 46 will slide relative to the air guide protrusion 47, and the air guide rod 45 will move up and down relative to the defrost rack 41 under the action of gravity, thereby driving each air guide rod 45 to adjust the pitch angle, thereby achieving the purpose of spraying carbon dioxide to extinguish the fire in different directions.

[0063] Further, by Figure 1 - Figure 4 It is given that, in order to increase the environmental performance of the equipment, the exhaust gas treatment system includes a paper box layer 48 and a connecting pipe, and the connecting pipe is connected to the outside of the chamber body 1;

[0064] It should be noted that the paper box layer 48 is a dry paper box filter box, which can preliminarily adsorb paint mist. The output end of the connecting pipe is also connected to a four-stage filter element, a zeolite wheel equipment and an RTO combustion device, which can effectively treat the exhaust gas and reduce the harm to the environment. The dry paper box filter box and the four-stage filter element can be replaced in time according to the pressure difference.

[0065] It should be emphasized that the thermal camera 4 is also connected to a PLC control unit, and each of the first motor 15, the second motor 23, and the solenoid valve 30 is electrically connected to the PLC control unit. The PLC control unit can control the number of revolutions and the speed of each first motor 15 and the second motor 23, and can control the opening and closing of each solenoid valve 30. When the thermal camera 4 captures an abnormal temperature somewhere in the chamber 1, it will first control the first motor 15 and the second motor 23 to move the horizontal platform 7 away from the abnormal heat source and move the longitudinal platform 6 to the lowest position. When the horizontal platform 7 moves to the farthest point, it will drive each horizontal platform 7 closer to the heat source, and at the same time open the solenoid valve 30 to spray carbon dioxide to the abnormal heat source through the fire cylinder 28 to extinguish the fire.

[0066] When the present invention is used, the passenger bus to be processed can be parked in the chamber 1 first, and then the longitudinal platform 6 and the transverse platform 7 of the three-dimensional lifting platform can be used to perform multi-process processing on the passenger bus, including: frame correction section, frame primer section, body putty section, body primer section, etc., which increases the practicability of the equipment for passenger bus processing. In different processing sections, the air supply system can adjust the temperature inside the chamber 1 so that the temperature inside the chamber 1 meets the processing and staff requirements. The exhaust gas treatment system is used to treat paint mist-containing air to meet environmental protection requirements. The staff can perform high-altitude operations through the transverse platform 7, which is convenient for operation. When a sudden power outage occurs, under the action of the rotary damper 18, the rotation speed of the active sprocket 16 will not be too fast, and the speed at which the longitudinal platform 6 descends under the action of gravity will not be too fast, which can protect the staff.

[0067] When the staff is working on the bus normally, they can stand on the transverse platform 7. At this time, the first guardrail 24 and the protective door 25 can protect the staff when working at a height. When the staff needs to move too far on the transverse platform 7, or needs to work together with the staff on another transverse platform 7, the two transverse platforms 7 can be brought closer to each other. At this time, the protective door 25 is opened, and the staff can move between the two transverse platforms 7, which is convenient for the staff to work flexibly.

[0068] When the thermal camera 4 detects that the temperature is higher than the preset value, the solenoid valve 30 will be opened through an electrical signal. At this time, the carbon dioxide liquid in the fire cylinder 28 will be gasified and pass through the first channel 29, the solenoid valve 30, the second channel 31 and the jet hole 32 in sequence, and then be ejected through the nozzle 33, thereby extinguishing the abnormally high temperature in the chamber body 1. At the same time, when the carbon dioxide enters the jet hole 32 through the second channel 31, it will drive the pneumatic turntable 34 to rotate through the power blade 35, and then drive the power turntable 36 to rotate unidirectionally. At this time, the sliding block 39 will slide in the sliding groove 38, thereby causing the first swing rod 37 to swing back and forth, and the second swing rod 40 to move back and forth. When the defrost rack 40 moves forward and backward, the defrost rack 41 will also be driven to move forward and backward relative to the horizontal platform 7. When the defrost rack 41 moves forward and backward with the second swing rod 40, the nozzle 33 will be defrosted by the defrost brush 42. When the defrost rack 41 moves forward and backward, the defrost rack 41 will rotate relative to the second swing rod 40. Since the air guide rod 45 can only move up and down along the defrost rack 41, the air guide protrusion 47 is fixedly connected to the second swing rod 40, that is, the air guide slider 46 will slide relative to the air guide protrusion 47, and the air guide rod 45 will move up and down relative to the defrost rack 41 under the action of gravity, thereby driving each air guide rod 45 to adjust the pitch angle, thereby achieving the purpose of spraying carbon dioxide to extinguish the fire in different directions.

[0069] The present invention has a novel structure, an ingenious conception, and is simple and convenient to operate. Through this design, the purpose of reducing fire hazards is effectively achieved, and it is convenient for workers to operate at high places on the bus, so that the workers can adjust the height more stably, and a function of descending protection for workers in a sudden power outage state is added, so that multiple workers can cooperate with each other to operate the bus, which is convenient for working at different positions of the bus, and the fire safety performance of the painting operation is increased. The effect of frost formed on the nozzle 33 on the gas ejection speed when the liquid carbon dioxide is gasified is reduced, and the function of both defrosting and automatically adjusting the fire extinguishing direction is added.

[0070] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
