Description

Technical Field

[0001] This invention relates to the field of anti-seepage wall washing technology, and in particular to an anti-seepage wall joint washing device. Background Technology

[0002] For deep foundation pit seepage prevention using plastic concrete cutoff walls, joint pipes are used for wall connections. After the subsequent cleaning and slurry replacement of the trenches, the mud skin adhering to the joint trench walls must be removed. Construction workers use wire brushes, driven by a drilling rig, to continuously move the brush back and forth from the bottom of the hole to the opening to scrub the mud skin adhering to the wall surface.

[0003] However, current scrubbing devices rely on being suspended inside the tank wall and moving up and down to scrub during the cleaning process. This method is inefficient, makes it difficult to observe the scrubbing process, and cannot automatically correct deviations when the device shifts. This can lead to inconsistent scrubbing results due to brush tilting. Summary of the Invention

[0004] This invention provides a scrubbing device for a waterproof wall joint, specifically comprising: a base, the main body of which is a cylindrical structure and has an internal hollow structure; a traction end fixedly connected to the top surface of the base, the traction end being a hook and used to install a traction rope; a universal ball fixedly connected to the outer circumference of the base for installation with a seat body; a through groove opened inside the seat body; an annular groove opened on the top surface of the seat body, with a guide plate installed inside the annular groove; and a bracket fixedly connected to the top of the seat body.

[0005] Optionally, a motor B is installed inside the base, an input shaft is installed on the bottom side of the motor B, and the motor B is connected to the reducer through the input shaft. An output shaft is installed on the bottom side of the reducer, and the output shaft installed on the bottom side of the reducer passes through the base and protrudes from the base.

[0006] Optionally, the top surface of the guide plate is equipped with an adjusting push rod in a circular array. The adjusting push rod is located on the outside of the base and is used to adjust the orientation of the base. The bottom side of the base is fixedly connected to a side plate. There are two side plates, and the two side plates are fixedly connected to the front and rear sides of the bottom end face of the base respectively. Electric push rods are installed on the outside of both side plates. The side plates and the base together form a load-bearing structure.

[0007] Optionally, the side of the electric push rod away from the side plate is connected to the limiting seat. The limiting seat has two legs A hinged in opposite directions inside. Each leg A has a leg B hinged to its bottom side. A spring rod is hinged inside every two laterally adjacent legs A. Guide wheels are installed on the bottom side of each leg B. The legs A and B together form a support structure.

[0008] Optionally, the guide ring is a ring structure, and a driver is installed on the rotating shaft part inside the base of one of the guide rings. Electromagnetic seats are fixedly connected to the inner sides of the two guide rings. The electromagnetic seats have grooves inside, and a pop-out plate is installed inside the groove of the electromagnetic seats by a spring. The pop-out plate is made of metal.

[0009] Optionally, a motor A is installed inside the transverse component of the bracket, and a gear is installed on the bottom side of the motor A. The motor A is used to drive the gear to rotate. Guide teeth are fixedly connected in a ring array on the outer circumferential surface of the guide disk rotatably connected to the top of the base. The guide teeth match the gear. When the gear rotates, the guide disk also rotates synchronously.

[0010] Optionally, a turntable is installed inside the pop-up plate, a driven shaft is installed at the top of the turntable, and brushes are fixedly connected in a ring array on the outer circumference of the turntable. A camera is fixedly connected to the bottom side of the turntable. When the electromagnetic base is de-energized, the pop-up plate is in an upward pop-up state.

[0011] Optionally, a chuck is installed on the bottom side of the output shaft mounted on the bottom side of the reducer. The chuck is a triangular chuck and is used to connect with the turntable. A spray seat is fixedly connected to the bottom end face of the base. Spray holes are opened in a ring array on the bottom end face of the spray seat. The spray seat sprays water downward through the spray holes via external water supply. Guide rings are rotatably connected to both the front and rear sides of the base.

[0012] Beneficial effects

[0013] According to an embodiment of the present invention, the brushing device, compared with the conventional one, when the base moves downward by the hoisting equipment, the support leg A in the limiting seat installed outside the electric push rod will first contact the ground with its bottom support leg B. Simultaneously, as the turntable moves downward, it will squeeze the spring rod installed inside the support leg A, making the downward movement of the turntable and brush more stable. This effectively avoids the brush from deviating due to external influences when the turntable moves downward. Even if the turntable deviates at an angle when it moves downward, the motor A installed on the top side of the bracket can be started to drive the gear to rotate. The gear will mesh with the guide teeth fixedly connected to the outside of the base to move the adjusting push rod to the appropriate position. The adjusting push rod will then push and adjust the orientation of the base installed inside the base, thereby achieving the purpose of forced correction. This design avoids the problem of inconsistent cleaning degree during the rinsing of the tank wall due to the deflection of the brush when the correction operation cannot be performed during the brushing process.

[0014] Furthermore, in this invention, when the turntable is driven by motor B to perform a brushing operation, the spray seat installed on the bottom side of the base can be activated to perform efficient spray cleaning of the turntable and brush through the spray holes arranged in a ring on its bottom side. This makes the brushing of the tank wall more thorough. During the brushing process, the current brushing status of the tank wall can be recorded in real time by a camera installed on the bottom side of the turntable. This allows external personnel to observe and judge the current brushing status of the tank wall without having to go inside the tank wall. This design can greatly improve work efficiency and allow for real-time adjustment of the cleaning level of the tank wall through intuitive observation.

[0015] Furthermore, in this invention, the motor B installed inside the base outputs power and is decelerated by a reducer to drive the turntable to rotate. Brushes arranged in a ring array on the outer circumference of the turntable then perform an efficient rotating scrubbing operation on the tank wall. Simultaneously, the height of the base is adjusted up and down using external hoisting equipment, thus achieving thorough and efficient scrubbing of the tank wall. This design can automatically and quickly change the type of brush required for scrubbing according to the different hardness of the inner wall to be scrubbed, thereby improving scrubbing efficiency. It effectively replaces the traditional manual brush replacement method, which easily leads to low work efficiency due to downtime. Attached Figure Description

[0029] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0030] Example: Please refer to Figures 1 to 8 :

[0031] This invention proposes a scrubbing device for a seepage-proof wall joint, comprising: a base 1, the main body of which is a cylindrical structure and has an internal hollow structure; a traction end 2 fixedly connected to the top surface of the base 1, which is a hook and is used to install a traction rope; a universal ball 3 fixedly connected to the outer circumference of the base 1 for installation with a seat body 4; a through groove opened inside the seat body 4; an annular groove opened on the top surface of the seat body 4; a guide plate 7 installed inside the annular groove opened in the seat body 4; a bracket 26 fixedly connected to the top of the seat body 4; a turntable 23 installed inside the pop-out plate 22; a driven shaft installed at the top of the turntable 23; brushes 24 fixedly connected in an annular array on the outer circumference of the turntable 23; and a camera 25 fixedly connected to the bottom side of the turntable 23. When the electromagnetic seat 21 is de-energized, the pop-out plate 22 is in an upward pop-up state. The side plate 10 and the seat body 4 together form a load-bearing structure.

[0032] Furthermore, according to embodiments of the present invention, such as Figures 1-3 As shown, a motor A5 is installed inside the transverse component of the bracket 26. A gear 6 is installed on the bottom side of the motor A5, which drives the gear 6 to rotate. Guide teeth 8 are fixedly connected in a ring array on the outer circumference of the guide disk 7 rotatably connected to the top of the base 4. The guide teeth 8 match the gear 6. When the gear 6 rotates, the guide disk 7 also rotates synchronously. Adjusting push rods 9 are installed in a ring array on the top surface of the guide disk 7. The adjusting push rods 9 are located on the outside of the base 1 and are used to adjust the orientation of the base 1. Side plates 10 are fixedly connected to the bottom side of the base 4. There are two side plates 10, which are fixedly connected to the front and rear sides of the bottom end face of the base 4, respectively. Electric push rods 11 are installed on the outer side of both side plates 10. When the base 1 moves downward by the hoisting equipment, the electric push rods 11 are installed on the outside of the electric push rods 11. The support leg A13 in the side limit seat 12 will first contact the ground with its bottom support leg B14. Simultaneously, as the turntable 23 moves downward, it will squeeze the spring rod 15 installed inside the support leg A13 to make the downward movement of the turntable 23 and brush 24 more stable. This effectively avoids the brush 24 from deviating due to external influences when the turntable 23 moves downward. Even if the turntable 23 deviates at an angle when it moves downward, the motor A5 installed on the top side of the bracket 26 can be started to drive the gear 6 to rotate. The gear 6 will mesh with the guide tooth 8 fixedly connected to the outside of the seat body 4 to move the adjusting push rod 9 to the appropriate position. The adjusting push rod 9 will push and adjust the orientation of the base 1 installed inside the seat body 4, thereby achieving the purpose of forced correction.

[0033] Furthermore, according to embodiments of the present invention, such as Figures 1-6As shown, the side of the electric push rod 11 furthest from the side plate 10 is connected to the limiting seat 12. The limiting seat 12 has two opposing support legs A13 hinged inside. Support legs B14 are hinged to the bottom of each of the two support legs A13. A spring rod 15 is hinged inside every two laterally adjacent support legs A13. Guide wheels are installed on the bottom of each of the two support legs B14. Support legs A13 and B14 together form a support structure. A motor B16 is installed inside the base 1. An input shaft is installed on the bottom of the motor B16, and the motor B16 is connected to the reducer 17 via the input shaft. An output shaft is installed on the bottom of the reducer 17. The output shaft installed on the bottom side passes through the base 1 and protrudes from the base 1. When the turntable 23 is driven by the motor B16 to perform the brushing operation, the spray seat 18 installed on the bottom side of the base 1 can be activated to perform efficient spray cleaning operation on the turntable 23 and the brush 24 through the spray holes in the annular array on its bottom side. This makes the brushing of the tank wall more thorough. In addition, during the brushing process, the camera 25 set on the bottom side of the turntable 23 can record the brushing of the tank wall in real time, so that external personnel can observe and judge the brushing of the tank wall without going deep into the tank wall.

[0034] Furthermore, according to embodiments of the present invention, such as Figures 1-8 As shown, a chuck 19 is mounted on the bottom side of the output shaft of the reducer 17. The chuck 19 has triangular jaws and is used to connect with the turntable 23. A spray seat 18 is fixedly connected to the bottom end face of the base 1. The bottom end face of the spray seat 18 has spray holes arranged in a ring array. The spray seat 18 sprays water downward through the spray holes via an external water supply. Guide rings 20 are rotatably connected to both the front and rear sides of the base 1. The guide rings 20 have a ring structure. A driver is also installed on the rotating shaft part inside the base 1 in one of the guide rings 20. Electromagnetic seats 21 are fixedly connected to the inner sides of the two guide rings 20. The electromagnetic seats 21 have grooves inside, and the grooves in the electromagnetic seats 21 are installed by springs. There is a pop-out plate 22, which is made of metal. The motor B16 installed inside the base 1 outputs power and the reducer 17 performs corresponding deceleration to drive the turntable 23 to rotate. The brushes 24, which are fixedly connected in a ring array on the outer circumference of the turntable 23, perform efficient rotating and brushing operations on the tank wall. At the same time, the height of the base 1 is adjusted up and down by external hoisting equipment, so as to achieve the purpose of thorough and efficient brushing of the tank wall. This design can automatically and quickly change the type of brush 24 required for brushing according to the different hardness of the inner wall to be brushed, thereby improving the brushing efficiency.

[0035] The specific usage and function of this embodiment: In this invention, firstly, the traction end 2 fixedly connected to the top of the base 1 is connected to the traction rope of the crane. Then, the base 1 is hoisted to a suitable position and placed. Then, the driver installed on one side of the guide ring 20 is started to drive the guide ring 20 to rotate. The guide ring 20 rotates and drives the brush 24 of the appropriate size to move to the position directly below the motor B16. Then, the power supply to the electromagnetic base 21 is deactivated so that the pop-out plate 22 can drive the rotating shaft installed at the top of the turntable 23 to be inserted into the internal position of the chuck 19 under the action of the spring. At the same time, the chuck 19 is started to limit and clamp the transmission shaft installed at the top of the turntable 23.

[0036] Then, the motor B16 installed inside the base 1 can be started to output power and the reducer 17 can be used to reduce the speed to drive the turntable 23 to rotate. The brushes 24 fixedly connected in a ring array on the outer circumference of the turntable 23 can perform efficient rotating brushing operation on the tank wall. At the same time, the height of the base 1 can be adjusted up and down by external hoisting equipment to achieve the purpose of thorough and efficient brushing of the tank wall. This design can automatically and quickly change the type of brushes 24 required for brushing according to the different hardness of the inner wall to be brushed, thereby improving the brushing efficiency.

[0037] Furthermore, when the turntable 23 is driven by the motor B16 to perform the brushing operation, the spray seat 18 installed on the bottom side of the base 1 can be activated to perform efficient spray cleaning operation on the turntable 23 and the brush 24 through the spray holes in the annular array on its bottom side, so that the brushing of the tank wall is more thorough. In addition, during the brushing process, the camera 25 set on the bottom side of the turntable 23 can record the brushing of the tank wall in real time, so that external personnel can observe and judge the brushing of the tank wall without going deep into the tank wall.

[0038] When the base 1 moves downward via the hoisting equipment, the support leg A13 in the limit seat 12 installed on the outside of the electric push rod 11 will first contact the ground with its bottom support leg B14. Simultaneously, as the turntable 23 moves downward, it will squeeze the spring rod 15 installed on the inside of the support leg A13 to make the downward movement of the turntable 23 and the brush 24 more stable. This effectively avoids the brush 24 from shifting due to external influences when the turntable 23 moves downward. Even if the turntable 23 shifts at an angle during its downward movement, the motor A5 installed on the top side of the bracket 26 can be activated to drive the gear 6 to rotate. The gear 6 will mesh with the guide tooth 8 fixedly connected to the outside of the base 4 to move the adjusting push rod 9 to the appropriate position. The adjusting push rod 9 will then push and adjust the orientation of the base 1 installed inside the base 4, thereby achieving the purpose of forced correction.

[0039] Finally, it should be noted that when describing the position of each component and the mating relationship between them, the present invention usually uses one or a pair of components as examples. However, those skilled in the art should understand that such positions, mating relationships, etc., are also applicable to other components or other pairs of components.
