Description

Technical Field

[0001] This utility model belongs to the technical field of chiseling devices for concrete construction, and in particular relates to a mobile chiseling device for concrete components. Background Technology

[0002] Currently, in the production of concrete components, the construction and renovation of various concrete floors, roughening is usually required to give the surface a certain roughness to ensure the adhesion of subsequent construction.

[0003] Traditional roughening methods mainly involve manual labor using small tools such as hand-held chisels, planers, axes, pneumatic picks, and electric picks to ensure a strong bond between new and old concrete. However, specialized roughening equipment developed based on this method is expensive. Consequently, high-pressure water guns have emerged as a method for roughening. Workers use hand-held high-pressure water guns for roughening. Since the roughening angle and distance are controlled by the workers based on experience, the roughening quality is poor. Furthermore, the recoil of the water jet gun makes it difficult to control the spray angle and distance. Long-term use also results in high labor intensity and is not suitable for continuous long-term roughening operations. Summary of the Invention

[0004] This invention addresses the problems of existing methods where workers manually use high-pressure water guns for roughening concrete components. Because the roughening angle and distance are controlled by the workers based on experience, the roughening quality is poor, and the recoil of the water jet makes it difficult to control the spray angle and distance. Furthermore, long-term use results in high labor intensity and is unsuitable for continuous, long-term roughening operations. This invention provides a mobile roughening device for concrete components. By adjusting the spray angle and height of the high-pressure water gun, a mobile trolley can be used to continuously roughen large concrete components. If needed, the high-pressure water gun can also be removed and manually used for roughening, making the process convenient and effective.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A mobile concrete component roughening device includes a trolley with a water supply mechanism and an installation mechanism. An adjustment mechanism is fixedly mounted on the installation mechanism. The adjustment mechanism includes an adjustment plate, a first gear, a second gear, two fixed plates, a rotating shaft, and a third gear. The first and second gears are rotatably mounted on the adjustment plate, and the second gear is connected to a first limiting mechanism to restrict its rotation. Two fixed plates are fixedly mounted opposite each other on one side of the first gear, and a rotating shaft and the third gear are rotatably mounted between the two fixed plates. One end of the rotating shaft is fixedly connected to the third gear. A second limiting mechanism is mounted on one of the fixed plates to restrict the rotation of the third gear. A mounting hole is passed through the side of the rotating shaft, and a high-pressure water gun is inserted into the mounting hole. A locking hole, perpendicular to and communicating with the mounting hole, is also provided on one side of the rotating shaft. A first bolt is threaded into the locking hole. Rotating the second gear drives the first gear to rotate, which, in conjunction with rotating the rotating shaft, adjusts the angle of the high-pressure water gun. After fixing the gun, the mobile trolley can be used to roughen large concrete components.

[0006] Preferably, the water supply mechanism includes a water tank fixedly mounted on the trolley, a water pump, and a take-up reel rotatably mounted on the trolley. A high-pressure water supply pipe is connected between the water pump outlet and the high-pressure water gun. The high-pressure water supply pipe passes around the take-up reel, and the water pump delivers water from the water tank to the high-pressure water gun through the high-pressure water supply pipe to achieve the roughening operation.

[0007] Preferably, the mounting mechanism includes multiple mounting plates fixedly disposed on the side of the trolley. The adjusting plate is fastened to the corresponding mounting plate by bolts. The mounting plate limits the movement of the device on the trolley and is also used for the installation of the adjusting mechanism.

[0008] Preferably, a support frame is fixedly provided on the inner side of multiple mounting plates, which further enhances the installation stability of the mounting plates.

[0009] Preferably, a first handle is fixedly installed on the upper side of one side of the trolley, and the trolley can be moved by pushing the first handle.

[0010] Preferably, the second gear is connected to a second handle for rotating the second gear, and the second gear is rotated by rotating the second handle.

[0011] Preferably, the first limiting mechanism includes a groove on one side of the adjusting plate, a locking block that slides up and down in the groove, a through hole on the upper side of the adjusting plate, and a second bolt threaded into the through hole. The lower end of the through hole is connected to the groove, and the lower end of the second bolt is rotatably connected to the bottom surface of the groove and its thread passes through one end of the locking block. The other end of the locking block is located between two adjacent teeth of the second gear. By rotating the second bolt, the locking block is driven to rise and fall in the groove, thereby adjusting whether the locking block controls the rotation of the second gear.

[0012] Preferably, a third handle is rotatably provided on one of the fixed plates. One end of the third handle passes through the corresponding fixed plate and is fixedly connected to the end of the rotating shaft for rotating the rotating shaft. The rotating shaft is rotated by rotating the third handle.

[0013] Preferably, the second limiting mechanism includes a third bolt, wherein a threaded hole is provided through one of the fixed plates, and the third bolt is threaded into the threaded hole. One end of the third bolt passes through the threaded hole and is located between two adjacent teeth of the third gear. The third bolt can be rotated to adjust whether its end extends between two adjacent teeth of the third gear.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model allows the high-pressure water gun to pass through the mounting hole and be effectively fixed and placed by rotating the first bolt. When needed, the first bolt can be loosened, and the high-pressure water gun can be held by hand to perform the roughening operation.

[0015] 2. This utility model, by fixing the high-pressure water gun to a rotating shaft, rotates the second gear to drive the first gear to rotate, adjusting the spray angle of the high-pressure water gun. Simultaneously, by rotating the rotating shaft, the spray angle of the high-pressure water gun is further adjusted, achieving flexible adjustment of the spray angle to adapt to roughening operations requiring different angles, thus improving the surface finish of the roughened concrete components. 3. This utility model achieves large-area roughening operations by adjusting the angle and fixing the high-pressure water gun on the trolley and moving the trolley, thereby improving the roughening quality, ensuring the uniformity of roughening, and making the operation flexible, simple, convenient and effective.

[0016] 4. By rotating the second bolt, the locking block is engaged between the teeth of the second gear, restricting the rotation of the second gear, and thus restricting the rotation of the first gear meshing with the second gear, thus preventing the high-pressure water gun spray angle from deflecting due to the rotation of the first gear during the roughening operation.

[0017] 5. This utility model, by rotating the third bolt, allows one end of the third bolt to extend between the teeth of the third gear, thereby restricting the rotation of the third gear and thus restricting the rotation of the shaft coaxially fixed to the third gear. This further prevents the high-pressure water gun from deflecting due to the rotation of the shaft during the roughening operation. Attached Figure Description

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-6 As shown, this embodiment provides a mobile chiseling device for concrete components, including a trolley 1. A first handle 17 is fixedly installed on the upper side of one side of the trolley 1, and the trolley 1 is moved by pushing the first handle 17.

[0026] As one possible implementation, the trolley 1 is provided with a drive mechanism, which is a motor or a motor reducer, used to drive the trolley 1 to move.

[0027] The trolley 1 is equipped with a water supply mechanism and an installation mechanism. The water supply mechanism includes a water tank 12 fixedly mounted on the trolley 1, a water pump 13, and a take-up reel 14 rotatably mounted on the trolley 1. A high-pressure water supply pipe is connected between the outlet of the water pump 13 and the high-pressure water gun 2. The high-pressure water supply pipe passes around the take-up reel 14. The water pump 13 transports the water in the water tank 12 to the high-pressure water gun 2 to spray out and perform the roughening operation. The take-up reel 14 is used to hold the high-pressure water supply pipe to prevent twisting and knotting, thereby ensuring smooth water delivery.

[0028] An adjustment mechanism is fixedly installed on the mounting mechanism. The mounting mechanism includes multiple mounting plates 15 fixedly installed on the side of the trolley 1. The adjustment mechanism includes an adjustment plate 3, a first gear 4, a second gear 5, two fixed plates 6, a rotating shaft 7, and a third gear 8. The adjustment plate 3 is fastened to the corresponding mounting plate 15 by bolts. Specifically, as needed, the adjustment plate 3 can be removed and installed on mounting plates 15 on different sides of the trolley and fastened. The first gear 4 and the second gear 5 are rotatably mounted on the adjustment plate 3. The second gear 5 is connected to a first limiting mechanism to limit the rotation of the second gear 5. The second gear 5 is connected to a second handle 18 for rotating the second gear 5. By rotating the second handle 18, the second gear 5 is driven to rotate, which in turn drives the first gear 4 to rotate.

[0029] The first limiting mechanism includes a groove 19 on one side of the adjusting plate 3, a locking block 20 that slides up and down in the groove 19, a through hole on the upper side of the adjusting plate 3, and a second bolt 21 threadedly connected in the through hole. The lower end of the through hole is connected to the groove 19. The lower end of the second bolt 21 is rotatably connected to the bottom surface of the groove 19 and threaded through one end of the locking block 20. The other end of the locking block 20 is located between two adjacent teeth of the second gear 5. When it is necessary to rotate the second gear 5 to the first gear 4, the second bolt 21 is rotated first, causing the locking block 20 to move upward in the groove 19, so that the locking block 20 disengages from the second gear 5. After the rotation angle of the second gear 5 is adjusted, the second bolt 21 is rotated in the opposite direction, causing the locking block 20 to move downward, so that the end of the locking block 20 extending out of the groove 19 is located between two adjacent teeth of the second gear 5, thus restricting the rotation of the second gear 5.

[0030] Two fixed plates 6 are fixedly arranged on one side of the first gear 4. A rotating shaft 7 and a third gear 8 are rotatably arranged between the two fixed plates 6. A second limiting mechanism is provided on one of the fixed plates 6 to limit the rotation of the third gear 8. One end of the rotating shaft 7 is fixedly connected to the third gear 8, and the rotating shaft 7 is coaxially fixedly connected to the third gear 8. A third handle 22 is rotatably arranged on one of the fixed plates 6. One end of the third handle 22 passes through the corresponding fixed plate 6 and is fixedly connected to the end of the rotating shaft 7 for rotating the rotating shaft 7. By rotating the third handle 22, the rotating shaft 7 is driven to rotate synchronously with the third gear 8.

[0031] The second limiting mechanism includes a third bolt 23. One of the fixing plates 6 has a threaded hole through it, and the third bolt 23 is threaded into the threaded hole. One end of the third bolt 23 passes through the threaded hole and is located between two adjacent teeth of the third gear 8. When it is necessary to rotate the shaft 7 to the third gear 8, the third bolt 23 is first rotated to move it away from the third gear 8, and then its end is disengaged from the third gear 8. After the rotation angle of the shaft 7 and the second gear 8 is adjusted, the third bolt 23 is rotated in the opposite direction, so that the end of the third bolt 23 extends into the space between two adjacent teeth of the third gear 8, thereby restricting the rotation of the third gear 8.

[0032] The rotating shaft 7 has a mounting hole 9 through its side, and a high-pressure water gun 2 is installed inside the mounting hole 9. The rotating shaft 7 also has a locking hole 10 that is perpendicular to and connected to the mounting hole 9 on one side. A first bolt 11 is threaded into the locking hole 10. By rotating the first bolt 11, the high-pressure water gun 2 inside the mounting hole 9 is fixed, and the high-pressure water jet from the high-pressure water gun 2 is used to perform the roughening operation.

[0033] Multiple mounting plates 15 are fixedly provided with support frames 16 on their inner sides. The support frames 16 further ensure the installation stability of the mounting plates 15 and their adjustment mechanisms.

[0034] When using it, first determine whether to manually hold the high-pressure water gun 2 or push the trolley 1 to perform the chipping operation. If it is manually held, simply loosen the first bolt 11 and then remove the high-pressure water gun 2 from the mounting hole 9. Then turn on the water pump 13 to transport the water in the water tank 12 to the high-pressure water gun 2 through the high-pressure water pipeline to achieve the chipping operation.

[0035] To drive the trolley for roughening operations, first rotate the second bolt 21 to the third bolt 23 to release the rotation limit on the second gear 5 and the third gear 8. Then, using the second handle 18 and the third handle 22, rotate the second handle 18 to drive the second gear 5 to rotate, which in turn drives the first gear 4 to rotate. Rotate the third handle 22 to drive the third gear 8 to rotate on the shaft 7, thereby adjusting the spray angle of the high-pressure water gun 2. After adjustment, rotate the second bolt 21 to the third bolt 23 in the opposite direction so that the locking block 20 locks onto the second gear 5 to restrict the rotation of the second gear 5 and the first gear 4. By locking the third gear 8 with the third bolt 23, the rotation of the third gear 8 and the shaft 7 is restricted. This ensures that the spray angle of the high-pressure water gun 2 does not change during the roughening operation, ensuring the uniformity of roughening and improving the roughening quality. Then, by moving the trolley 1, roughening is performed on different positions of the concrete component, effectively improving roughening efficiency and reducing labor intensity.

[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
