[0032] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.
[0033] Please see Figures 1 to 7 The present invention provides a technical solution:
[0034] Example 1: A wall crack repair device for residential construction includes: a grouting gun 3, a vacuum gun 1, a cleaning gun 2, and a hollow frame 5.
[0035] Specifically, one end of the grouting gun 3 is provided with a grouting nozzle 31, the dust suction gun 1 is located above the grouting gun 3, and one end of the dust suction gun 1 is provided with a dust suction nozzle 11. The dust suction nozzle 11 is used to absorb dust in the wall cracks, and the grouting nozzle 31 injects grout into the cracks.
[0036] Secondly, the cleaning gun 2 is located between the vacuum gun 1 and the grouting gun 3, and the vacuum gun 1, cleaning gun 2, and grouting gun 3 are fixedly connected in sequence. A partition 21 is fixedly installed in the middle of the cleaning gun 2, and a guide plate 4 is installed in the inner cavity of one side of the cleaning gun 2. One end of the guide plate 4 extends to the outer side of one end of the cleaning gun 2, and a synchronous belt 41 is provided on the outer side of the guide plate 4. The surface of the synchronous belt 41 is provided with blades 42, such as... Figure 2 As shown, the guide plate 4, the timing belt 41, and the blade 42 work together to form the structure of the electric saw. The timing belt 41 can rotate along the edge of the guide plate 4. When the end of the guide plate 4 extends into the wall crack, the blade 42 can cut the concrete blocks and other debris in the crack. At the same time, the debris is carried out of the crack by the rotation of the timing belt 41 until the debris and some dust fall into the inner cavity on the other side of the cleaning gun 2. The other part of the dust can be sucked away by the dust suction nozzle 11, thereby reducing the debris in the wall crack and ensuring that the grout can repair it better. The other end of the guide plate 4 is provided with a drive wheel axle 43 for driving the timing belt 41 to rotate. The drive wheel axle 43 is used to drive the timing belt 41 to rotate.
[0037] Furthermore, the hollow frame 5 is fixed to the inner cavity of the cleaning gun 2. A connecting slider 51 is slidably installed in the inner cavity of the hollow frame 5. The end of the drive wheel shaft 43 is rotatably inserted into the connecting slider 51. An adjusting screw 54 for driving the connecting slider 51 to slide is threaded through the middle of the connecting slider 51. Figure 3 and Figure 6 It can be seen that the rotation of the adjusting screw 54 can drive the connecting slider 51 to slide along the inner cavity of the hollow frame 5, thereby driving the drive wheel shaft 43 to move, and thus adjusting the distance of the guide plate 4 extending out. In other words, when the port of the cleaning gun 2 of this device is in contact with the wall, the operator can adjust the depth of the guide plate 4 into the wall crack by turning the adjusting screw 54 at the tail of the cleaning gun 2, thereby achieving good cleaning of the crack.
[0038] In Example 2, based on Example 1, in order to reduce the shaking of the guide plate 4, the partition 21 of this application divides the inner cavity of the cleaning gun 2 into two spaces. The guide plate 4 and the hollow frame 5 are located on both sides of the partition 21. The surface of the partition 21 is provided with an adjustment slot 52 corresponding to the hollow frame 5. The drive wheel shaft 43 passes through the adjustment slot 52 and is slidably connected to it. The adjustment slot 52 is provided to guide the sliding of the drive wheel shaft 43, so that the guide plate 4 can only extend and retract along its own length direction and is not easy to shake to the side.
[0039] In embodiment three, based on embodiment two, this application further includes a connecting sleeve 53 fixedly installed inside the hollow frame 5, an adjusting screw 54 rotatably connected to the connecting sleeve 53, and an adjusting knob 55 fixedly connected to the end of the adjusting screw 54 extending to the outside of the cleaning gun 2. After the connecting sleeve 53 is connected to the adjusting screw 54, the adjusting screw 54 can only rotate and will not move. Therefore, when the adjusting screw 54 rotates, it can drive the connecting slider 51 to slide through the thread.
[0040] In Example 4, based on Example 3, in order to store debris inside the cleaning gun 2, one end of the cleaning gun 2 is configured as an open structure, and the opening shape is "L". A sealing pressure plate 22 is fixedly connected to the edge of one end of the cleaning gun 2. A sealing gasket is adhered to the surface of the sealing pressure plate 22 and it is in contact with the wall. Figure 2 As shown, the synchronous belt 41 rotates counterclockwise. After the synchronous belt 41 rotates and brings the debris to the port of the cleaning gun 2, the debris is separated by the partition 21 and can fall to the side of the partition 21 away from the guide plate 4. This facilitates the storage of debris and reduces the contact between the debris and the guide plate 4, thereby preventing the synchronous belt 41 from getting stuck when it rotates.
[0041] In embodiment five, based on embodiment four, to facilitate cleaning of debris from the inner cavity of the cleaning gun 2, this application further includes an opening for discharging debris on the side of the cleaning gun 2 away from the guide plate 4, and a side plate 23 is rotatably mounted at the opening. A handle 25 is mounted on the surface of the side plate 23, and a limiting protrusion 24 is provided at the edge of the side plate 23 to be fixed to the side opening of the cleaning gun 2. Figure 2 As shown, the side plate 23 and the cleaning gun 2 are connected by a hinge. The side plate 23 can be rotated to the vertical direction and block the opening on the side of the cleaning gun 2. At this time, the limiting protrusion 24 limits the side plate 23 to prevent the side plate 23 from easily rotating and opening the opening. When the staff needs to clean the debris inside the cleaning gun 2, they only need to pull the handle 25 to make the side plate 23 pass over the limiting protrusion 24.
[0042] In embodiment six, based on embodiment five, in order to drive the drive wheel shaft 43 to rotate, this application further includes a drive motor 6 provided on the outside of the cleaning gun 2, the output end of the drive motor 6 being fixedly connected to the drive wheel shaft 43, and a motor base 61 slidably provided on the side of the cleaning gun 2, the drive motor 6 being fixedly mounted to the surface of the motor base 61 by bolts, as shown below. Figure 5 and Figure 6 As shown, when the drive motor 6 is working, it can drive the drive wheel shaft 43 to rotate, and the drive motor 6 can move along with the drive wheel shaft 43.
[0043] In embodiment seven, based on embodiment six, this application further includes protruding plates 62 fixedly connected to both the upper and lower sides of the motor base 61. A guide frame 7 is provided on the surface of the protruding plate 62 to press against it. The guide frame 7 is fixedly connected to the side of the cleaning gun 2. Figure 7 As shown, after the guide frame 7 presses the convex plate 62, the convex plate 62 can slide along the length direction of the guide frame 7, but will not move away from the cleaning gun 2. Therefore, the drive motor 6 and the motor base 61 can move in the same direction as the drive wheel shaft 43.
[0044] In embodiment eight, based on embodiment seven, to prevent the motor base 61 from rotating, this application further includes a guide groove 71 extending through the surface of the guide frame 7, and a guide post 63 fixedly connected to the surface of the protruding plate 62. The end of the guide post 63 extends into the inner cavity of the guide groove 71 and is slidably connected thereto. Figure 7 As shown, after the guide post 63 and the guide groove 71 are engaged, the motor base 61 can be prevented from rotating around the drive wheel shaft 43. Therefore, when the drive motor 6 is working, it can drive the drive wheel shaft 43 to rotate normally, thereby avoiding the reaction force generated when the drive motor 6 is working from causing the motor base 61 to rotate.
[0045] In Example 9, based on Example 8, the vacuum gun 1 of this application is connected to the end of an external vacuum cleaner through an air pipe, and the grouting gun 3 is connected to an external grouting pump through a grout delivery pipe. Both the grouting pump and the vacuum cleaner are installed on the repair vehicle. Both the vacuum cleaner and the grouting pump use the structure in the prior art, which will not be described in detail here. In addition, the repair vehicle is also equipped with a grout tank with a stirring structure to store the grout used to repair wall cracks.
[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
