Description

Technical Field

[0001] This utility model relates to the field of steel plate cleaning technology, specifically to a cleaning device for steel plates in a steel-covered air cushion pressure regulating chamber before welding. Background Technology

[0002] The steel-shrouded air cushion pressure regulating chamber is a type of pressure regulating structure used in hydropower projects. It is primarily constructed using a combination of a supporting structure and steel plates. Steel plates are welded and fixed between the supporting structures within the pressure regulating chamber, thereby improving the overall strength of the chamber during operation. To ensure the welding and fixing effect between the steel plates and the supporting structure, the steel plates need to be cleaned before welding to prevent residual dirt and impurities from affecting the connection and fixation during the welding process. Existing cleaning methods mostly involve manual rinsing within the pressure regulating chamber, a time-consuming and labor-intensive process that increases the workload for construction workers. Therefore, we propose a pre-welding cleaning device for the steel plates of the steel-shrouded air cushion pressure regulating chamber. Utility Model Content

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a cleaning device for steel plates in a steel-covered air cushion pressure regulating chamber before welding, including a cleaning platform 1, a cleaning groove 2 inside the cleaning platform 1, a clamping mechanism 3 for clamping and fixing the steel plate fixedly installed inside the cleaning groove 2, a driving mechanism 4 fixedly installed on the rear side wall of the cleaning platform 1, the output end of the driving mechanism 4 being fixedly connected to the cleaning mechanism 5, the driving mechanism 4 driving the cleaning mechanism 5 to move repeatedly in the left and right directions along the cleaning groove 2, completing the cleaning treatment of the steel plate in the cleaning groove 2, and a drain pipe 6 connected to the cleaning groove 2 being fixedly connected to the side wall of the cleaning platform 1, the waste liquid produced during the cleaning process can be discharged through the drain pipe 6.

[0018] like Figure 1 As shown, the clamping mechanism 3 includes a bottom bracket 31, which is symmetrically welded to the side wall of the cleaning tank 2 on the left and right. A fixing frame 32 is fixedly mounted on the side wall of the cleaning tank 2 on the left and right. A hydraulic telescopic cylinder 33 is fixedly mounted in the middle of the fixing frame 32. A clamping plate 34 is fixedly mounted through the fixing frame 32 at the output end of the hydraulic telescopic cylinder 33. The hydraulic telescopic cylinder 33 is connected to an external hydraulic control pipeline. The action of the output end of the hydraulic telescopic cylinder 33 is controlled by the external hydraulic control pipeline. The hydraulic telescopic cylinder 33 drives the clamping plate 34 to move, which works with the bottom bracket 31 to clamp and fix the steel plate.

[0019] like Figure 2 As shown, the drive mechanism 4 includes a drive screw 41, which is rotatably connected to the rear side wall of the cleaning table 1. A drive motor 42 is fixedly mounted on the side wall of the cleaning table 1. The output end of the drive motor 42 is fixedly connected to the end of the drive screw 41 through a coupling. The drive motor 42 is electrically connected to an external power supply and an external controller. The drive motor 42 drives the drive screw 41 to rotate. Contact switches (not shown in the figure) are fixedly mounted on the side walls of the fixed blocks at both ends of the drive screw 41. If the moving block 43, which is screwed to the outer side wall of the drive screw 41, comes into contact with one of the contact switches during the movement of the drive screw 41, the contact switch sends an electrical signal to the external controller. At this time, the external controller controls the drive motor 42 to move in the opposite direction, thereby realizing the reciprocating cyclic movement of the moving block 43 along the drive screw 41.

[0020] A movable frame 44 is welded and fixed to the top of the movable block 43. An assembly frame 45 is fixedly connected to the top side wall of the movable frame 44. The assembly frame 45 is used for assembling the cleaning mechanism 5. The movable block 43 can drive the movable frame 44 and the assembly frame 45 to move.

[0021] like Figure 2 As shown, a limiting frame 7 that passes through the movable frame 44 is fixedly mounted on the side wall of the cleaning table 1. The limiting frame 7 can increase the stability of the movable frame 44 and the assembly frame 45 during the movement stroke.

[0022] like Figure 2 and Figure 3 As shown, a limiting groove 8 is provided on the top side wall of the cleaning table 1, and a limiting pulley assembly groove 9 is provided in the side wall of the movable frame 44. A limiting pulley 10 is installed in the limiting pulley assembly groove 9. The limiting pulley 10 is slidably connected in the limiting groove 8. By setting the limiting pulley 10, the assembly frame 45 can be supported, and the stability of the connection and fixation between the movable frame 44 and the assembly frame 45 can be further enhanced.

[0023] like Figure 3 As shown, the cleaning mechanism 5 includes a cleaning roller brush 51, which is rotatably connected to the assembly frame 45. A spray pipe 52 is fixedly installed in the assembly frame 45. There are two spray pipes 52, which are symmetrically distributed on the left and right sides of the cleaning roller brush 51 in the assembly frame 45. By setting the symmetrically distributed spray pipes 52, cleaning liquid can be sprayed on both sides of the cleaning roller brush 51, thereby enhancing the cleaning effect of the cleaning roller brush 51 on the steel plate. Nozzles are evenly fixedly installed at the bottom of the spray pipe 52, and the cleaning liquid is sprayed downward through the nozzles.

[0024] A liquid supply pipe 53 is fixedly connected to the top of the spray pipe 52. The liquid supply pipe 53 has one input end and two output ends. The two output ends supply cleaning liquid to the spray pipe 52 respectively. One end of the connecting hose 54 is fixedly connected to the input end of the liquid supply pipe 53. The other end of the connecting hose 54 is fixedly connected to the liquid supply pump 55. The liquid supply pump 55 is fixedly mounted on the top of the cleaning table 1. The liquid supply pump 55 is electrically connected to an external power source. The input end of the liquid supply pump 55 is fixedly connected to an external cleaning liquid supply unit. The liquid supply pump 55 supplies cleaning liquid into the spray pipe 52 through the connecting hose 54. The connecting hose 54 does not affect the left and right movement of the mounting frame 45 along the cleaning table 1.

[0025] Working Principle: This utility model is mainly used in the construction of steel-covered air cushion pressure regulating chambers. It is used to clean the support steel plates before welding to avoid residual impurities on the surface of the steel plates, which would affect the stability of the connection and fixation of the steel plates during the welding process. The steel plates to be cleaned are inserted into the cleaning groove 2. The bottom bracket 31 lifts the steel plates, and then the hydraulic telescopic cylinder 33 controls the clamping plate 34 to press down in conjunction with the bottom bracket 31 to clamp and fix the steel plates. The drive mechanism 4 drives the cleaning mechanism 5 to move along the surface of the steel plates. The cleaning roller brush 51 can wash away the impurities on the surface of the steel plates. The waste liquid generated during the cleaning process enters the cleaning groove 2 and is then discharged out through the drain pipe 6. Spray pipes 52 are set on both sides of the cleaning roller brush 51 in the cleaning mechanism 5, which can spray the cleaning liquid onto the surface of the steel plates more evenly during the movement of the cleaning roller brush 51, thereby improving the cleaning effect of the cleaning liquid on the surface of the steel plates.
