Description

Technical Field

[0001] This utility model relates to the field of spray booth technology, specifically a telescopic spray booth. Background Technology

[0002] A sandblasting booth, also known as a shot blasting booth or sandblasting room, is suitable for cleaning and removing rust from the surfaces of large workpieces, and for increasing the adhesion between the workpiece and the coating. During large-scale construction, a large number of prefabricated structures / accessories need to be sandblasted on-site to improve the mechanical properties of the workpiece surface, thus facilitating anti-corrosion coating.

[0003] A search revealed a Chinese utility model patent with publication number CN208231599U, which discloses a mobile sandblasting booth. According to its description, by setting support columns and rollers at the bottom of the crossbeam frame and setting telescopic shear frames between two adjacent sets of columns, the size of the sandblasting booth can be adjusted by pushing the front support columns, thereby avoiding the problems of existing sandblasting booths occupying a large space and being inconvenient to move.

[0004] However, the sandblasting room in the above patent has the following problems: (1) It requires manual pulling or pushing of the crossbeam frame to drive the telescopic shear frame to retract or unfold, which is inconvenient to use; (2) When the sandblasting room is unfolded, if the length of the sandblasting room is long, the sandblasting area is large, and the position of the sandblasting pipe is not adjustable, it cannot move together with the length of the sandblasting room, making it difficult for the polluted gas in the sandblasting room to be discharged in time. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention provides a telescopic spray booth to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A telescopic spray booth includes two sets of parallel guide rails, a front beam frame slidably connected to the two guide rails, and a rear beam frame fixed to the guide rails. Multiple columns are arranged between the front and rear beam frames, and adjacent columns are connected by telescopic shear frames. Canvas is connected to the top of the columns and both sides of the telescopic shear frames. A first pulley is connected to the lower end of the columns, and a second pulley is connected to the lower end of the front beam frame. Both the first and second pulleys are slidably connected to the guide rails. The front beam frame is also equipped with a drive mechanism for driving the second pulley to slide on the guide rails.

[0008] Preferably, the guide rail assembly includes a base block, two guide rails mounted on the base block, and mounting ears connected to both sides of the base block, with screw holes provided on the mounting ears.

[0009] In the above technical solution, the guide rail is fixed to the base block, and the base block is connected to the ground by bolts. During installation, it is not necessary to install the guide rail one by one. The base block can be fixed to the ground according to the on-site construction conditions and the width of the sandblasting room, which improves the convenience of installation.

[0010] Preferably, the lower end of the column is rotatably connected to a first rotating shaft, and the two ends of the first rotating shaft are connected to first pulleys. The two first pulleys on the same first rotating shaft slide on two guide rails on the same base block, respectively.

[0011] In the above technical solution, the column is slidably connected to two guide rails by two first pulleys, which can improve the stability of the column when sliding and prevent the column from falling off the guide rails.

[0012] Preferably, two second rotating shafts are rotatably connected to the lower ends of both sides of the front beam frame, and two second pulleys are connected to the two ends of the second rotating shafts. The second pulleys on the two second rotating shafts on the same side slide on two guide rails on the same base block.

[0013] In the above technical solution, two second pulleys are provided on both sides of the front beam frame to improve the stability of the front beam frame when it moves.

[0014] Preferably, the drive mechanism includes a reduction motor mounted on the lower part of both sides of the front beam frame, a drive shaft connected to the reduction motor via a coupling, two drive wheels connected to the drive shaft, and a driven wheel connected to the outer end of the second rotating shaft. The two drive wheels on the same side are respectively connected to the two driven wheels on the same side via a drive belt.

[0015] The above technical solution simultaneously activates the reduction motors on both sides of the front beam frame. The reduction motors on the same side operate, and through the cooperation of two driving pulleys, two transmission belts, and two driven pulleys, they drive the two second rotating shafts on the same side to rotate simultaneously, thereby moving the second pulleys on the guide rail. When both reduction motors operate simultaneously, they can drive the second pulleys on both sides of the front beam frame to move simultaneously, improving both power and stability.

[0016] Preferably, the lower part of the rear beam frame is connected to two exhaust ports, and each exhaust port is connected to a corrugated pipe with telescopic function. The end of the corrugated pipe away from the exhaust port is connected to an air inlet. The lower part of the air inlet is connected to a connecting plate. The lower part of the middle column on both sides is connected to an extension plate. The two extension plates are respectively connected to the two connecting plates by screws.

[0017] In the above technical solution, the exhaust port is located on the rear beam frame, and the air inlet is connected to the middle column. When the sandblasting chamber is extended, the air inlet will also be extended, so that the air inlet is always in the middle of the sandblasting chamber, that is, the distance between the air inlet and the front and rear sides of the sandblasting chamber is the same, so as to discharge the dirty gas in time.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The second pulleys on both sides of the front beam frame are driven by the drive mechanism to move on the guide rail group, realizing the automatic unfolding of the sandblasting room without manual pushing and pulling, which improves the efficiency of sandblasting room length adjustment.

[0020] (2) The exhaust port is located on the rear beam frame, and the air inlet is connected to the middle column. When the sandblasting room is extended, the air inlet will also be extended, so that the air inlet is always in the middle of the sandblasting room, that is, the distance between the front and rear sides of the sandblasting room and the air inlet is the same, so as to discharge the dirty gas in time.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figures 1-4A telescopic spray booth includes two sets of parallel guide rails 1, a front beam frame 2 slidably connected to the two guide rails, and a rear beam frame 3 fixed to the guide rails. Multiple columns 4 are arranged between the front beam frame 2 and the rear beam frame 3. Adjacent columns 4 are connected by telescopic shear frames 5. Canvas is connected to the top of the columns 4 and both sides of the telescopic shear frames 5. The canvas will expand or contract with the telescopic shear frames.

[0030] like Figure 4 As shown, the guide rail assembly 1 includes a base block 101, two guide rails 102 mounted on the base block, and mounting ears 103 connected to both sides of the base block. The mounting ears 103 have screw holes. The guide rails 102 are fixed to the base block 101, which is bolted to the ground. During installation, it is not necessary to install each guide rail individually; the base block can be fixed to the ground according to the site conditions and the width of the sandblasting booth, thus improving installation convenience.

[0031] The lower end of the column 4 is rotatably connected to a first rotating shaft 8, and both ends of the first rotating shaft 8 are connected to first pulleys 6. The two first pulleys 6 on the same first rotating shaft 8 slide on two guide rails 102 on the same base block. The lower ends of both sides of the front beam frame 2 are rotatably connected to two second rotating shafts 9, and both ends of the second rotating shafts 9 are connected to second pulleys 10. The second pulleys on the two second rotating shafts 9 on the same side slide on two guide rails 102 on the same base block. The column 4 is slidably connected to the two guide rails 102 by two first pulleys 6, which can improve the stability of the column 4 when sliding. Two second pulleys 10 are provided on both sides of the front beam frame 2, which can improve the stability of the front beam frame 2 when moving.

[0032] The front beam frame 2 is also equipped with a drive mechanism that drives the second pulley 7 to slide on the guide rail assembly 1. Figure 2 As shown, the drive mechanism includes a reduction motor 11 mounted on the lower part of both sides of the front beam frame 2, a transmission shaft connected to the reduction motor via a coupling, two drive wheels 12 connected to the transmission shaft, and a driven wheel 13 connected to the outer end of the second rotating shaft. The two drive wheels 12 on the same side are respectively connected to the two driven wheels 13 on the same side via a transmission belt 14. When the reduction motors 11 on both sides of the front beam frame 2 are started simultaneously, the reduction motors 11 on the same side work, and through the cooperation of the two drive wheels 12, the two transmission belts 14, and the two driven wheels 13, they drive the two second rotating shafts 9 on the same side to rotate simultaneously, thereby driving the second pulleys 7 to move on the guide rail 102. When the two reduction motors 11 work simultaneously, they can drive the second pulleys 7 on both sides of the front beam frame 2 to move simultaneously, which improves both power and stability.

[0033] Example 2

[0034] The difference between this embodiment and embodiment 1 is that the lower part of the rear beam frame 3 is connected to two exhaust ports 15, and each exhaust port 15 is connected to a corrugated pipe 16 with telescopic function. The end of the corrugated pipe 16 away from the exhaust port is connected to an air inlet 17. The lower part of the air inlet 17 is connected to a connecting plate 18, and the lower part of the uprights 4 in the middle on both sides is connected to an extension plate 19. The two extension plates 19 are respectively connected to the two connecting plates 18 by screws.

[0035] The exhaust port 15 is located on the rear beam frame 3, and the air inlet 17 is connected to the middle column 4. The air inlet 17 is connected to the exhaust port 15 fixed to the rear beam frame 3 through a corrugated pipe 16 with flexible telescopic properties. When the drive mechanism drives the column 4 to slide along the guide rail to extend the sandblasting chamber, the middle column 4 drives the air inlet 17 to move synchronously away from the rear beam frame 3, and stretches the corrugated pipe 16 so that its length increases with the increase of the column displacement. This ensures that the air inlet 17 always remains in the middle position of the chamber axis during the chamber's extension and contraction, ensuring that the suction point is adjusted synchronously with the change of the working area so as to discharge the waste gas in a timely manner.
