[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0027] like Figs. 1-3 As shown, a grouting device for defect repair includes a base plate 1, with rollers 7 at the rear end of the bottom of the base plate 1, support legs 8 at the front end of the bottom of the base plate 1, and a vertical bracket 2 installed at the rear end of the top of the base plate 1, with a handle 6 on the bracket 2; it also includes a grout storage tank 4, which is placed vertically on the base plate 1 and fixed to the bracket 2. The grout storage tank 4 and the bracket 2 are compactly installed on the upper surface of the base plate 1, such that the distance between the support legs 8 and the rollers 7 is less than the width of a conventional stair tread; it also includes a grouting pipe 42 and a pressure pump 41, with the pressure pump 41 installed on the grout storage tank 4, one end of the grouting pipe 42 connected to the grout storage tank 4, and the other end of the grouting pipe 42 equipped with a grouting head 43.

[0028] The tread width of a staircase refers to the horizontal length of each step, i.e., the actual length of the step. It determines the space for your feet to land.

[0029] This invention uses a grout storage tank 4 as a storage container for epoxy mortar. When placed vertically, the grout storage tank 4 occupies a small area at its bottom, requiring a smaller base plate 1. Support legs 8 and rollers 7 are respectively installed at the front and rear ends of the base plate 1. Workers can lift the base plate 1 by holding the handle 6, allowing the support legs 8 to levitate and push the invention for transport. When transporting between different floors, the small area of ​​the base plate 1 allows the entire invention to be placed on a single step for balance, and then manually lifted by a single worker to the next step, thus solving the problem of existing grouting devices being unable to maintain balance on stairs and thus requiring single-person operation to cross floors. Because a support bracket 2 is installed at the rear end of the top of the base plate 1, and the base plate 1 provides installation space for the bracket 2, the width of the base plate 1 is ideally less than its length. Placing the invention sideways on the stairs saves space and facilitates transport. The grout storage tank 4, used to store the epoxy mortar required for grouting, has good sealing properties to prevent grout leakage. The roller 7 is preferably made of wear-resistant rubber, which has good rolling performance and facilitates the movement of the device. When the device is stopped, the support legs 8 provide stable support, ensuring stability during grouting. The pressure pump 41 provides a certain pressure to the grout in the storage tank 4, ensuring smooth grout output. The grouting pipe 42 has a certain degree of flexibility, facilitating the guidance of the grout to the required grouting location. The grouting pipe 42 is equipped with a grouting head 43, the design of which allows the grout to be injected evenly into the defective area.

[0030] Furthermore, the bracket 2 is provided with a vertically oriented groove 21, and a slider 22 is provided within the groove 21. The two sides of the slider 22 abut against the side walls of the groove 21. A motor 5 is installed at the bottom of the groove 21, and the output end of the motor 5 is connected to a lead screw 51. The lead screw 51 passes through the slider 22 and is threadedly connected to the slider 22. When the motor 5 drives the lead screw 51 to rotate, the slider 22 moves within the groove 21 along the direction of the groove 21. The handle 6 is connected to the slider 22. By setting up the groove 21 and the slider 22, and connecting the handle 6 to the slider 22, the position of the slider 22 in the groove 21 can be adjusted by rotating the motor 5 in both directions, i.e., adjusting the height of the slider 22 and the handle 6. When operators of different heights operate this utility model, the height of the handle 6 can be adjusted by controlling the motor 5, thereby enabling operators to control this utility model more comfortably and conveniently during use, ensuring the smooth progress of the grouting operation. The motor 5 is preferably a geared motor 5, which has a precise speed regulation function and can achieve smooth lifting and lowering of the slider 22. The lead screw 51 has a high-precision thread, and the slider 22 also has a corresponding high-precision thread. The lead screw 51, together with the slider 22, can accurately transmit power.

[0031] Furthermore, it also includes a U-shaped clamp 61, which is fixedly connected to the slider 22. The inner walls of the two sides of the U-shaped clamp 61 are clamped to the outer walls of the two sides of the bracket 2. The specific structure of the handle 6 connected to the slider 22 is as follows: the handle 6 is respectively installed on the outer walls of the two sides of the U-shaped clamp 61, and the U-shaped clamp 61 is connected to the slider 22. The handle 6 is connected to the slider 22, which is sliding. Because it is movable, the connection strength is not high enough. The addition of the U-shaped clamp 61, one side of the U-shaped clamp 61 is fixedly connected to the slider 22, and the two sides clamp the bracket 2 and abut against the bracket 2, increases the force-bearing surface, making the connection between the handle 6 and the bracket 2 more stable. The U-shaped clamp 61 and the bracket 2 only abut against each other, and there is no situation where clamping would prevent movement. As long as the two sides of the U-shaped clamp 61 are attached to the two sides of the bracket 2, the support can be completed without causing clamping and immobilization.

[0032] Furthermore, the slurry storage tank 4 is fixed to the support 2 by at least two clamps 3, which are fitted onto the outer wall of the slurry storage tank 4 and fixedly installed on the support 2. The clamps 3 complete the fixation of the slurry storage tank 4. The clamps 3 are a common structure that can be opened or locked from the side to complete the fixation or removal of the slurry storage tank 4.

[0033] Furthermore, a storage battery is installed inside the bottom of the bracket 2, and the storage battery is connected to the motor 5. In embodiments where the storage battery is not installed, the motor 5 can be connected to a fixed power source, and then the rotation of the motor 5 can be controlled, so the transfer and adjustment do not need to be synchronized. Setting the storage battery to power the motor 5 means that the adjustment of the motor 5 is not limited by the power supply.

[0034] Furthermore, the connection between one end of the grouting pipe 42 and the grout storage tank 4 is specifically as follows: one end of the grouting pipe 42 is connected to a discharge valve pipe 44, which is connected to the grout storage tank 4. The discharge valve pipe 44 allows for the control of grout discharge by switching it on and off.
