Technical Field

[0001] The utility model relates to the technical field of painting sealing, in particular to a pretreatment tank top sealing device suitable for workpiece swinging in a painting production line. Background Art

[0002] At present, in the vertical lifting production line for painting pretreatment, the temperature of the hot water spray tank is often higher than 50°C. After the workpiece enters the tank and starts spraying, a large amount of steam will be generated. This requires covering the tank to prevent hot air from escaping, reduce heat loss, and reduce corrosion of surrounding equipment. The traditional method is to set a sealing cover on the top of the spreader and set a sealing strip on the tank edge. The top member of the spreader directly falls on the sealing strip on the tank edge to achieve sealing.

[0003] In order to drain the accumulated water and impurities inside the vehicle body and improve the cleaning effect. Now, the vehicle manufacturers require that the workpiece can swing during the spraying process so that the accumulated water and impurities inside the workpiece can be smoothly drained. However, due to the limitations of the sealing cover and the sealing strip, the swinging amplitude is limited or even difficult to swing, which affects the cleaning effect.

[0030] Embodiment

[0031] Reference Figures 1 - 6 , a pretreatment tank top sealing device suitable for workpiece swinging disclosed by the present utility model, includes a spray pool 1 with an open upper surface, a spray head 2 arranged inside the spray pool 1 for spraying, and two sealing covers 3 respectively hinged on both sides of the spray pool 1; the present utility model further includes a driving component 4 for driving the rotation of the sealing cover 3 and a swinging component 5 for swinging the vehicle body.

[0032] Specifically, the side parts of the two sealing covers 3 are respectively connected to the two side edges of the spray pool 1 through a rotating shaft, so as to realize the rotation of the sealing cover 3 on the edge of the spray pool 1;

[0033] Furthermore, a sealing strip 6 is arranged on one adjacent side end face of the two sealing covers 3, and the other adjacent side end face is arranged as a stepped structure 7 adapted to the sealing strip 6 for accommodating the sealing strip 6; the thickness of the sealing strip 6 is less than the thickness of the sealing cover 3, and the upper surface of the sealing strip 6 is flush with the upper surface of the sealing cover 3; when the spray pool 1 is in a sealed state, the sealing cover 3 is placed on the stepped structure 7 without gaps, further realizing the sealing;

[0034] Two completely penetrating and symmetrically arranged front and rear relief openings 8 are provided on the sealing strip 6 and the stepped structure 7, and the width of the relief opening 8 is the same as the widths of the sealing strip 6 and the stepped structure 7;

[0035] In this embodiment, the swinging component 5 includes two elevators (not shown in the figure) and two traction chains 9 connected to the elevators. The two traction chains 9 are respectively in vertical sliding fit with the two relief openings 8; hooks 10 are arranged at the bottoms of the two traction chains 9, and the same lifting tool 11 is suspended by the two hooks 10. Two groups of vertically arranged suspension rods 12 are hinged on both sides of the lifting tool 11 through a hinge shaft, and a skid 13 for carrying the vehicle body is arranged at the bottom ends of the two groups of suspension rods 12. It is worth noting that the specific structure of the skid 13 and the connection method with the vehicle body are all well-known common knowledge in the art and will not be elaborated in detail here;

[0036] Furthermore, support plates 14 are respectively arranged on the outer walls on both sides of the spray pool 1, support angle steels 15 are respectively arranged between the lower surfaces of the two support plates 14 and the side walls of the spray pool 1, guide columns 16 are respectively arranged on the upper surfaces of the two support plates 14 close to the spray pool 1, and guide pulleys 17 are respectively arranged on the two guide columns 16;

[0037] In this embodiment, the driving assembly 4 includes two electric hoists 18 respectively arranged on the upper surfaces of the two support plates 14. Cable stays 19 are respectively arranged at the output ends of the two electric hoists 18. The other ends of the two cable stays 19 are respectively wound around the adjacent guiding pulleys 17 and then connected to the adjacent sealing covers 3.

[0038] The working principle and beneficial effects of the present utility model are as follows:

[0039] In the initial state, the two sealing covers 3 are in the vertical state. When the vehicle body needs to be sprayed, the vehicle body is installed on the sled 13, and the vehicle body is conveyed downward to the spraying pool 1 through the two elevators. Then, the electric hoist 18 near the stepped structure 7 is started, and the cable stay 19 is slowly relaxed, so that the sealing cover 3 connected thereto gradually tends to be horizontal from the vertical under the action of gravity. During this process, the traction chain 9 is caught in the relief opening 8 formed in the stepped structure 7; then the electric hoist 18 on the other side is started, and the other sealing cover 3 gradually tends to be horizontal, and the traction chain 9 is simultaneously caught in the relief opening 8 formed in the sealing strip 6; the nozzle 2 is opened for spraying. During this process, the two elevators drive the two traction zippers to move vertically in opposite directions, thereby driving the spreader 11 to swing, and thus driving the vehicle body to swing.

[0040] Specifically: when the front traction chain 9 of the spreader 11 in the horizontal state descends and the rear traction chain 9 ascends, the spreader 11 presents a state of being lower in the front and higher in the rear. At this time, the front boom 12 moves downward and the rear boom 12 moves upward, driving the vehicle body to make a lowering movement, and vice versa. With the change of the height of the traction chain 9, finally, while maintaining the seal, the workpiece is swung, which is convenient for draining the accumulated water and impurities inside the vehicle body, helps to improve the cleaning effect, and can minimize the escape of hot air in the spraying pool 1 to the greatest extent.

[0041] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the various embodiments of the present utility model.
