[0004] However, during the process of pouring the device into the hole, the poured concrete is prone to sedimentation, which seriously affects the work progress of the device during the repair process, so it needs to be improved. Utility Model Content

[0005] In order to improve the problem that concrete is easy to deposit and is inconvenient to pour, the present application provides a walking bridge inspection and repair device.

[0006] The present application provides a walking bridge inspection and repair device that adopts the following technical solution:

[0007] A walking bridge inspection and repair device comprises a mounting plate, a mixing box and a discharge pipe, wherein the mixing box is arranged on the mounting plate, the discharge pipe is connected to the bottom of the mixing box, a rotating rod is arranged in the mixing box, the rotating rod is arranged horizontally, a motor is arranged on the mixing box, the output end of the motor is coaxially fixed with one end of the rotating rod, and is used to drive the rotating rod to rotate about the central axis of the rotating rod, and a plurality of stirring rods are fixed on the rotating rod.

[0008] By adopting the above technical scheme, when in use, first move the installation plate with the mixing box to the crack of the bridge, then pour the repair concrete into the mixing box, start the motor, drive the rotating rod to rotate, so that a number of mixing rods push the concrete while supporting the concrete to move, that is, the concrete in the mixing box is stirred, the concrete is not easy to settle in the mixing box, and the concrete always has a certain fluidity, so that it is convenient for the concrete to flow out through the discharge pipe, and pour the concrete on the crack of the bridge to repair the crack.

[0009] Optionally, the rotating rod is connected to a moving rod via a connecting rod, the moving rod is parallel to the rotating rod, and the moving rod can move around the rotating rod as an axis.

[0010] By adopting the above technical solution, when the motor drives the rotating rod to rotate, the connecting rod drives the moving rod to rotate around the rotating rod. During this process, the moving rod moves in the gap between the stirring rod and the inner wall of the mixing box, thereby pushing and stirring the concrete that the stirring rod fails to abut, thereby achieving stirring of the concrete between the stirring rod and the inner wall of the mixing box, thereby achieving more comprehensive stirring of the concrete in the mixing box, further reducing the possibility of concrete sedimentation, and facilitating the flow of concrete.

[0011] Optionally, a plurality of abutment rods are fixed on the moving rod, the abutment rods are perpendicular to the moving rod, and the plurality of abutment rods are arranged at intervals on the moving rod.

[0012] By adopting the above technical solution, when the moving rod moves, it drives the abutment rod to move between the mixing rod and the inner wall of the mixing box. Several abutment rods cooperate with the moving rod to increase the contact area with the concrete, increase the amount of concrete pushed by the moving rod when it moves, and thus improve the comprehensiveness of mixing concrete.

[0013] Optionally, an internal gear is fixed on the inner wall of the mixing box, and the internal gear is coaxial with the moving rod. One end of the moving rod is rotatably connected to the connecting rod, and a rotating gear is coaxially fixed to the other end. The moving rod can rotate around the central axis of the moving rod, and the rotating gear is located inside the internal gear and meshes with the internal gear.

[0014] By adopting the above technical solution, when the moving rod moves, it drives the rotating gear to move in the internal gear. During this process, the rotating gear meshes with the internal gear, thereby driving the rotating gear to rotate, so that the moving rod will rotate while revolving around the rotating rod, so that the abutting rod stirs the concrete it contacts while pushing the concrete, thereby accelerating the mixing efficiency and further improving the comprehensiveness of the mixing.

[0015] Optionally, a receiving groove is provided on the inner wall of the mixing box, the internal gear and the rotating gear are both located in the receiving groove, a baffle for blocking the receiving groove is provided on the inner wall of the mixing box, the baffle is rotatably connected to the inner wall of the receiving groove via a rotating shaft, the rotating shaft is coaxial with the internal gear, the moving rod passes through the baffle, and the moving rod can drive the baffle to rotate.

[0016] By adopting the above technical solution, when the moving rod revolves, it drives the baffle to rotate, so that the receiving groove is always in a closed state, so that concrete is not easy to enter the receiving groove, that is, it is not easy for the concrete to get stuck between the adjacent teeth on the internal gear and the rotating gear, so that the rotating gear and the internal gear can maintain a meshing state, thereby ensuring that when the moving rod moves, it can achieve self-rotation under the cooperation of the rotating gear and the internal gear. At the same time, the moving rod is inserted into the baffle, so that the distance from the moving rod to the center of the baffle is fixed, thereby limiting the moving rod, so that the moving rod is not easy to deviate during the process of moving around the rotating rod, and increasing the stability of the movement of the moving rod.

[0017] Optionally, a rubber pad is provided on the side wall of the baffle, and the rubber pad abuts against the inner wall of the mixing box.

[0018] By adopting the above technical solution, when the moving rod drives the baffle to rotate, the rubber pad slides on the mixing box, and the rubber pad plays a protective role, making it difficult for the baffle and the inner wall of the mixing box to wear, thereby extending the service life of the baffle and the mixing box.

[0019] Optionally, a magnet is embedded in the rubber pad, and the magnet can fit into the inner wall of the mixing box.

[0020] By adopting the above technical solution, when the baffle rotates on the mixing box, the magnet is always in contact with the inner wall of the mixing box, so that the rubber pad is pressed against the inner wall of the mixing box, making it difficult for the concrete in the mixing box to pass through the gap between the rubber pad and the inner wall of the mixing box into the containing tank, thereby increasing the airtightness of the opening of the containing tank.

[0021] Optionally, the bottom wall of the mounting plate is provided with a plurality of rollers.

[0022] By adopting the above technical solution and the setting of the roller, the operator can directly push the installation plate to move, so as to facilitate the movement of the mixing box to the crack of the bridge, and the operation is convenient.

[0023] In summary, the present application includes at least one of the following beneficial effects:

When using, first move the installation plate with the mixing box to the crack of the bridge, then pour the repair concrete into the mixing box, start the motor, drive the rotating rod to rotate, so that several mixing rods push the concrete while supporting the concrete to move, that is, to achieve the mixing of the concrete in the mixing box, so that the concrete is not easy to settle in the mixing box, that is, the concrete always has a certain fluidity, so that the concrete is easy to flow out through the discharge pipe, and pour the concrete at the crack of the bridge to achieve the repair of the crack;

[0025] 2. When the motor drives the rotating rod to rotate, the connecting rod drives the moving rod to rotate around the rotating rod. During this process, the moving rod moves in the gap between the stirring rod and the inner wall of the mixing box, thereby pushing and stirring the concrete that the stirring rod cannot reach, thereby stirring the concrete between the stirring rod and the inner wall of the mixing box, thereby achieving more comprehensive stirring of the concrete in the mixing box, further reducing the possibility of concrete deposition, and facilitating the flow of concrete.

[0034] Reference Figure 1 and Figure 2 A connecting rod 42 is fixed on the rotating rod 40, and the connecting rod 42 is located at the end of the rotating rod 40. The end of the connecting rod 42 away from the rotating rod 40 is connected to the moving rod 50, and one end of the moving rod 50 is rotatably connected to the connecting rod 42, that is, the moving rod 50 can rotate on the connecting rod 42.

[0035] When the motor 30 drives the rotating rod 40 to rotate, the connecting rod 42 drives the moving rod 50 to rotate around the rotating rod 40. During this process, the moving rod 50 moves with the abutment rod 51 in the gap between the stirring rod 41 and the inner wall of the mixing box 20, so as to push and stir the concrete that the stirring rod 41 fails to abut, thereby achieving more comprehensive mixing of the concrete in the mixing box 20, further reducing the possibility of concrete sedimentation, and facilitating the flow of concrete.

The rubber pad 71 fills the gap between the baffle 70 and the inner wall of the mixing box 20 to prevent concrete from entering the receiving groove 22. A magnet 711 is also embedded in the rubber pad 71, and the magnet 711 can be attracted to the inner wall of the mixing box 20, thereby increasing the tightness between the rubber pad 71 and the mixing box 20 and improving the airtightness. The moving rod 50 passes through the baffle 70, and the moving rod 50 can drive the baffle 70 to rotate.

[0039] When the moving rod 50 revolves, it drives the baffle 70 to rotate, so that the receiving groove 22 is always in a closed state, so that concrete is not easy to enter the receiving groove 22, that is, it is not easy for the concrete to get stuck between the adjacent teeth on the internal gear 60 and the rotating gear 52, so that the rotating gear 52 and the internal gear 60 can maintain a meshing state, thereby ensuring that when the moving rod 50 moves, it can achieve self-rotation under the cooperation of the rotating gear 52 and the internal gear 60. At the same time, the moving rod 50 is inserted into the baffle 70, so that the distance from the moving rod 50 to the center of the baffle 70 is fixed, thereby limiting the moving rod 50, so that the moving rod 50 is not easy to deviate during the process of moving around the rotating rod 40, and the stability of the movement of the moving rod 50 is increased.
