Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to an epoxy mortar coating device for defect repair. Background Technology

[0002] Epoxy mortar is a high-performance repair material with epoxy resin as the main agent, mainly used for the reinforcement, repair and corrosion protection of concrete structures.

[0003] In water conservancy projects, epoxy mortar is frequently used for defect repair, playing a crucial role in ensuring the stability and safety of the project. Defect repair refers to the process where, due to long-term water erosion and environmental factors, various defects easily appear on the surface of concrete structures in water conservancy projects. Epoxy mortar can effectively fill these defects, restoring the integrity and strength of the structure.

[0004] In current defect repair work, the main method is for construction workers to manually fill gaps with putty scrapers. In most cases, the workers need to squat down and manually smooth the surface with the putty scraper, which is physically demanding and inefficient. Utility Model Content

[0005] The purpose of this invention is to provide an epoxy mortar coating device for defect repair, thereby improving the efficiency of defect repair work and solving the problems in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] An epoxy mortar coating device for defect repair includes a cover, in which a motor and a coating disc are installed. A drive gear is installed at the output end of the motor, and the drive gear meshes with a driven gear. The driven gear is connected to the coating disc through a connecting shaft. The rotation of the driven gear drives the coating disc to rotate. An inclined notch is provided at the bottom of the coating disc, so that part of the bottom of the coating disc is a horizontal surface and the other part is an inclined surface. The side wall of the coating disc is attached to the inner wall of the cover.

[0008] Furthermore, it also includes a rotary disc, and the driven gear is connected to the coating disc specifically as follows: the bottom of the driven gear is connected to the rotary disc, and the bottom of the rotary disc is connected to the coating disc through multiple elastic clamping members; the elastic clamping members include guide posts, the top of which passes through the rotary disc, allowing the guide posts to move up and down on the rotary disc; a compression spring is sleeved on the guide post, one end of which is connected to the rotary disc, and the other end of which is connected to the coating disc; it also includes a limit cap, which is installed on the top of the guide post to restrict the guide post from dislodging from the rotary disc.

[0009] Furthermore, a top cover is installed on the top of the cover, a bracket is installed on the top of the top cover, and handles are installed on both sides of the upper end of the bracket.

[0010] Furthermore, reinforcing plates are provided on both sides of the lower end of the bracket, and the reinforcing plates are connected to the top cover.

[0011] Furthermore, pressure plates are respectively provided on the bottom of both sides of the cover.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0013] Epoxy mortar is piled up at the location where defects need to be repaired. The cover is used to cover the area to be repaired and the epoxy mortar at the same time, forming a sealed space. The motor drives the brush plate to rotate. The rotating brush plate smooths the epoxy mortar to complete the defect repair. The motor-driven brush plate repair increases work efficiency and also eliminates the need for workers to manually fill defects with a putty scraper, reducing physical exertion.

Detailed Implementation

[0023] 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.

[0024] like Figure 1 , Figure 2 , Figure 4 , Figure 7 As shown, an epoxy mortar coating device for defect repair includes a cover 1, inside which a motor 4 and a coating disc 2 are installed. A drive gear 41 is installed at the output end of the motor 4, and the drive gear 41 meshes with a driven gear 42. The driven gear 42 is connected to the coating disc 2 via a connecting shaft 43. Rotation of the driven gear 42 drives the coating disc 2 to rotate. The bottom of the coating disc 2 has an inclined notch, making part of the bottom of the coating disc 2 horizontal and the other part inclined. The sidewall of the coating disc 2 fits against the inner wall of the cover 1. During operation, epoxy mortar is piled up at the location requiring defect repair. The cover 1 is used to cover the area to be repaired along with the epoxy mortar. After covering, the motor 4 drives the coating disc 2 to rotate, and the rotation of the coating disc 2 smooths the epoxy mortar, completing the defect repair. The bottom of the coating disc 2 has an inclined notch, making one part of the bottom of the coating disc 2 horizontal and the other part inclined. During the rotation of the coating disc 2, the horizontal part rotates to smooth the epoxy mortar, while the inclined notch provides a certain amount of space to accommodate excess epoxy mortar during the repair process. The epoxy mortar accumulates in the space of the inclined notch, and as the coating disc 2 rotates, the inclined notch rotates along with it, causing the inclined surface at the bottom of the coating disc 2 to compress the epoxy mortar, thus completing the filling and repair process. In this embodiment, the motor 4 is connected to a switch, which is located outside the housing 1, and the motor 4 is driven manually by the switch.

[0025] like Figure 3 , Figure 5 , Figure 6 As shown, further, it also includes a rotary disc 3. The driven gear 42 is connected to the coating disk 2 specifically as follows: the bottom of the driven gear 42 is connected to the rotary disc 3, and the bottom of the rotary disc 3 is connected to the coating disk 2 through multiple elastic clamping members 31; the elastic clamping member 31 includes a guide post 311, the top end of which passes through the rotary disc 3, allowing the guide post 311 to move up and down on the rotary disc 3; a compression spring 312 is sleeved on the guide post 311, one end of which is connected to the rotary disc 3, and the other end of which is connected to the coating disk 2; it also includes a limiting cap 313, which is installed on the top of the guide post 311 to prevent the guide post 311 from dislodging from the rotary disc 3. The rotary disc 3 and the elastic clamping member 31 are provided to apply pressure to the coating disk 2 using the compression spring 312, thereby improving the quality of epoxy mortar smoothing defects.

[0026] like Figure 2 As shown, the bottom horizontal plane of the coating disk 2 is lower than the bottom plane of the cover 1. Therefore, during the defect repair process, when the bottom of the cover 1 is pressed against the ground, so that the bottom of the coating disk 2 is also pressed against the ground, the compression spring 312 is in a compressed state. The compressed compression spring 312 exerts a thrust on the coating disk 2, thereby applying pressure to the coating disk 2, squeezing and smoothing the epoxy mortar at the defect more tightly, and improving the quality of epoxy mortar smoothing defects. The limit cap 313 is installed on the top of the guide post 311 to prevent the guide post 311 from coming off the bottom of the rotary table 3.

[0027] Furthermore, a top cover 5 is installed on the top of the cover 1, and a bracket 6 is installed on the top of the top cover 5. Handles 7 are respectively installed on both sides of the upper end of the bracket 6. With the top cover 5 and the bracket 6, and the handles 7 installed on both sides of the bracket 6, the operator can directly hold the handles 7 to adjust or stabilize the present invention during use.

[0028] Furthermore, reinforcing plates 61 are respectively provided on both sides of the lower end of the bracket 6, and the reinforcing plates are connected to the top cover 5. The reinforcing plates increase the connection strength between the bracket 6 and the top cover 5.

[0029] Furthermore, pressure plates 8 are respectively provided on the bottom of both sides of the cover 1. The pressure plates 8 increase the contact area between the present invention and the ground, making it less prone to swaying during the operation of the coating disc 2, resulting in a smoother surface after defect repair. Secondly, the pressure plates 8 also provide a pressing surface for the worker, allowing them to use their own weight to press the present invention against the reaction force generated by the compression spring 312. Specifically, the reaction force refers to the fact that when the compression spring 312 is in a compressed state, it not only presses the coating disc 2 downwards but also presses the rotating disc 3 upwards. If the worker does not press the present invention firmly, the cover 1 will detach from the ground, becoming unstable. The conventional solution to this problem is for the worker to continuously apply a certain downward force to keep the cover 1 from detaching from the ground. However, by providing the pressure plates 8, the worker can apply pressure using their own weight, reducing the worker's physical exertion. Figure 8 As shown, the pressure plate 8 is equipped with anti-slip grooves to prevent slippage when workers step on it, making it more stable.
