[0022] Please see Figures 1-7 This utility model provides a technical solution for a high-pressure water jet device for breaking bridge diaphragms: Example

[0023] according to Figure 1 and Figure 2 As shown, a high-pressure water jet device for removing bridge diaphragms is used to remove diaphragms in the removal area. It includes a T-frame 1, a guide rail assembly 2, a longitudinal movement mechanism 3, a swing mechanism 4, and a high-pressure spray gun 5. The T-frame 1 guides the device into the narrow working area of ​​the bridge diaphragm to achieve narrow-distance removal. Specifically, the guide rail assembly 2 is fixed by the T-frame 1. The longitudinal movement mechanism 3 is installed on the guide rail assembly 2 and moves longitudinally along it. The high-pressure spray gun 5 is mounted on the longitudinal movement mechanism 3 via a swing seat 6. The longitudinal movement mechanism 3 also includes a swing mechanism 4 for controlling the left and right swing of the high-pressure spray gun 5. The demolition device is controlled by an existing multi-functional water milling robot. It is connected to the demolition device by the telescopic and rotating arm at the front end of the multi-functional robot. Due to the limited space, a rigid connection is not convenient. The demolition device is placed in the working position by the robot's swing arm movement. The robot arm can only assist in lifting and moving the device. Therefore, a flexible connection is used here. The demolition device is assisted in lifting and moving by connecting high-pressure oil pipes and control lines, and the movement of the demolition device is controlled. During construction, the T-shaped frame 1 is fixed to the bridge deck with expansion bolts, and the demolition device is extended into the construction gap of the bridge diaphragm. The high-pressure spray gun 5 is connected to the water source through a water pipe to spray water at high pressure. At the same time, the swing mechanism 4 controls the left and right swing of the high-pressure spray gun 5, and the longitudinal movement mechanism 3 moves on the guide rail group 2 to drive the high-pressure spray gun 5 to move longitudinally, so as to realize the construction operation of water jet demolition of concrete.

[0024] like Figure 3 As shown, the T-shaped frame 1 consists of a vertically arranged horizontal frame 11 and a vertical frame 12. The horizontal frame 11 is attached to the bridge, and the vertical frame 12 extends into the construction area. The guide rail assembly 2 is fixed longitudinally within the construction area via the vertical frame 12. The guide rail assembly 2 includes two parallel longitudinal tracks 21, which are connected and fixed by reinforcing ribs 22. A fixing frame 24 is installed and fixed behind the guide rail assembly 2 via the reinforcing ribs 22. The guide rail assembly 2 is fixed to the lower end of the vertical frame 12 via the fixing frame 24 and is arranged parallel to it. A toothed rail 23 is longitudinally installed and fixed within the two longitudinal tracks 21 via the reinforcing ribs 22. According to Figure 3 and Figure 4As shown, the longitudinal movement mechanism 3 includes a longitudinal movement mounting plate 31. Multiple pulleys 35 are rotatably mounted on the longitudinal movement mounting plate 31 in a rectangular arrangement. The longitudinal movement mounting plate 31 is slidably engaged with the longitudinal movement track 21 by the pulleys 35 and is controlled by the drive mechanism to slide up and down on the guide rail assembly 2. A hydraulic motor 32 is mounted on the longitudinal movement mounting plate 31. The output end of the hydraulic motor 32 is connected to the reducer 33. A gear 34 is fixedly mounted on the output end of the reducer 33, and the gear 34 meshes with the toothed rail 23 of the guide rail assembly 2. The hydraulic motor 32 and the reducer 33 control the rotation of the gear 34. Under the meshing transmission of the gear 34 and the toothed rail 23, the longitudinal movement mechanism 3 can be controlled to move up and down longitudinally on the guide rail assembly 2. The pulleys 35 play a limiting and guiding role, so that the longitudinal movement mechanism 3 can drive the high-pressure spray gun 5 to move stably longitudinally on the guide rail assembly 2.

[0025] A swing seat 6 is provided on the longitudinal sliding mounting plate 31, such as Figure 4 and Figure 5 As shown, the swing base 6 specifically includes a spray gun base 61. Two clamping plates 62 are symmetrically arranged inside the spray gun base 61. One clamping plate 62 is directly fixed inside the spray gun base 61, and the other clamping plate 62 is movably arranged inside the spray gun base 61. A push-pull rod 64 is connected to the outside of the movable clamping plate 62. The push-pull rod 64 is movably inserted through and fitted into the side wall of the spray gun base 61. A locking bolt 63 is installed on the side wall of the spray gun base 61. The locking bolt 63 is used to lock the movable clamping plate 62. The high-pressure spray gun 5 is inserted through the spray gun base 61 and is locked and fixed to the spray gun base 61 by the clamping plates 62 on both sides, so that the high-pressure spray gun 5 is stably installed on the longitudinal movement mechanism 3.

[0026] Two pin seats 66 are symmetrically installed on the longitudinal mounting plate 31 above and below the spray gun holder 61. The spray gun holder 61 is rotatably fitted into the pin seats 66 via upper and lower pins. Through the rotational engagement of the pins and pin seats 66, the spray gun holder 61 and the high-pressure spray gun 5 inside can swing left and right. Furthermore, a swing mechanism 4 for controlling the left and right swing of the spray gun holder 61 is installed on the longitudinal mounting plate 31, specifically as follows: Figure 6 As shown, a mounting base 41 is fixedly installed on the front side wall of the longitudinal mounting plate 31. A swing hydraulic cylinder 42 is mounted on the longitudinal mounting plate 31 via the mounting base 41. The output end of the swing hydraulic cylinder 42 is connected to a telescopic swing arm 43, and a pin seat 65 is fixed on the side wall of the spray gun base 61. The inner telescopic end of the telescopic swing arm 43 is rotatably fitted with the pin seat 65 via a pin shaft. The operation of the swing hydraulic cylinder 42 drives the telescopic swing arm 43 to swing back and forth. The swing of the telescopic swing arm 43 pulls the spray gun base 61 to swing, thereby realizing the left and right swing spraying effect of the high-pressure spray gun 5.

[0027] In practical use, this utility model's high-pressure water jet device for breaking bridge diaphragms, taking a beam spacing of 60cm, a height of 180cm, and a diaphragm width of 50cm to be broken as an example: the horizontal frame 11 of the T-shaped frame 1 is fixed to the bridge deck with expansion bolts, and the longitudinal frame 12 extends the entire breaking device into the front side of the breaking area under the bridge. During the breaking operation, high-pressure water is sprayed through the high-pressure spray gun 5, while the hydraulic cylinder 42 operates, driving the telescopic swing arm 43 to swing back and forth. The swing of the telescopic swing arm 43 pulls the spray gun base 61 to swing, controlling the left and right swing of the high-pressure spray gun 5. High-pressure water jets break up concrete. The high-pressure spray gun 5 swings to break up a width of about 10 centimeters. While the high-pressure spray gun 5 swings, the hydraulic motor 32 starts synchronously. Through the meshing of the gear 34 and the toothed rail 23, the longitudinal movement mechanism 3 moves on the guide rail group 2, driving the high-pressure spray gun 5 to move longitudinally, completing the breaking up of an area 1.8 meters high and 10 centimeters wide. After the breaking up of the current position is completed, the fixing expansion bolts are loosened, the T-shaped frame 1 is moved 10 centimeters to the left and then fixed again, and the above breaking up work is continued until the area 50 centimeters wide is completely broken up. After the operation is completed, the equipment is dismantled and moved to the next construction position. Example

[0028] Based on Embodiment 1, the similarities between this embodiment and Embodiment 1 will not be repeated here. The differences are as follows: To improve the convenience of the T-shaped frame 1 driving the breaking device to move left and right, such as Figure 7 As shown, two sliding blocks 7 can be placed on the left and right sides of the bridge, and the T-shaped frame 1 can be slidably set in the sliding blocks 7, with the left and right movement controlled by a hydraulic cylinder 9. Specifically, a slide rail is provided inside the sliding block 7, and movable wheels 8 are symmetrically installed on both sides below the crossbeam 11 of the T-shaped frame 1. The T-shaped frame 1 slides directionally in the slide rail of the sliding block 7 through the movable wheels 8, and a hydraulic cylinder 9 is horizontally installed at the inner end of one side of the sliding block 7. The extension and retraction output end of the hydraulic cylinder 9 is connected and fixed to the end of the T-shaped frame 1.

[0029] In practical use, the high-pressure water jet device for breaking bridge diaphragms of this utility model has a sliding seat 7 installed on the bridge by fixing bolts. The breaking device performs the concrete breaking operation as described in Example 1. After the breaking operation of 10cm width is completed, the hydraulic cylinder 9 is activated to extend, which can push the T-shaped frame 1 to move in the sliding seat 7, so that the T-shaped frame 1 drives the breaking device to move automatically to the left.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
