Description

Technical Field

[0001] This utility model relates to the technical field of base surface grinding equipment, and in particular to a base surface grinding device for hydraulic roughening construction. Background Technology

[0002] During water conservancy construction, concrete bridge piers in water-related areas are prone to surface cracking and freeze-thaw erosion. Repair work often requires a large amount of manual labor. However, the roughness-reducing protective coating has excellent mechanical properties, weather resistance, strong adhesion to the substrate, is less affected by external temperature and humidity, and has outstanding abrasion performance. It is suitable for protecting concrete from freeze-thaw erosion defects and surface carbonization in water conservancy and hydropower projects. The construction process generally includes cleaning and grinding the substrate, repairing holes with special putty, applying primer, and applying the SK roughness-reducing protective coating. In the existing technology, substrate grinding requires manual hand-held grinding discs and the use of scaffolding or suspended platforms for construction, which is time-consuming, labor-intensive, inefficient, and poses significant safety hazards. Utility Model Content

[0003] The purpose of this invention is to provide a base surface grinding device for hydraulic roughening construction, so as to solve the technical problems of time-consuming, labor-intensive and inefficient base surface grinding construction in the prior art.

[0004] The present invention relates to a base surface grinding device for water conservancy roughening construction, comprising two semi-circular buckles that are fastened together and connected by bolts. Several elastic telescopic grinding roller assemblies are installed inside the buckles and are slidably connected to a frame. A drive assembly is installed on the frame and drives the elastic telescopic grinding roller assemblies to move upward.

[0005] Furthermore, the elastic telescopic grinding roller assembly includes a U-shaped frame, within which a grinding roller is rotatably connected. The grinding roller is driven by a motor. Two sliding columns are horizontally connected on the U-shaped frame. Two sliding through holes matching the sliding columns are formed on the retaining ring. The sliding columns are slidably connected to the sliding through holes. A limiting platform is connected to the end of each sliding column. The limiting platform is located outside the retaining ring. A compression spring is connected to the U-shaped frame, and the other end of the compression spring contacts the retaining ring.

[0006] Furthermore, a connecting plate is connected to the outer wall of the buckle, a slide rail is connected to the connecting plate, and a vertical groove matching the slide rail is provided on the frame, with the slide rail slidably connected to the slide groove.

[0007] Furthermore, the drive assembly includes a wire rope, one end of which is connected to a buckle, and the other end of which passes over a fixed pulley and is connected to a winch. The fixed pulley is fixedly mounted on the frame.

[0008] Furthermore, the surface of the grinding roller is concave arc-shaped.

[0009] Furthermore, braked casters are installed on the bottom surface of the frame.

[0010] The beneficial effects of this utility model are as follows: The design of the buckle-type elastic telescopic grinding roller assembly allows the grinding roller to maintain elastic contact with the construction surface, resulting in a good grinding effect. At the same time, the design of the winch drive assembly drives the elastic telescopic grinding roller assembly to move up and down, eliminating the need to erect scaffolding for grinding construction at high points on bridge piers. The construction is fast, convenient, safe and reliable, and is worthy of widespread promotion and use. Attached Figure Description

Detailed Implementation

[0012] like Figure 1 As shown, a base surface grinding device for water conservancy roughening construction includes two semi-circular buckles 1 that are fastened together. The two buckles 1 are connected by bolts. Several elastic telescopic grinding roller assemblies are installed inside the buckles 1. The elastic telescopic grinding roller assemblies are slidably connected to the frame 11. A drive assembly is installed on the frame 11. The drive assembly drives the elastic telescopic grinding roller assemblies to move upward.

[0013] like Figure 1 and Figure 2As shown, the elastic telescopic grinding roller assembly includes a U-shaped frame 2, within which a grinding roller 3 is rotatably connected. The grinding roller 3 is driven by a motor 4. Two sliding columns 5 are horizontally connected on the U-shaped frame 2. Two sliding through holes matching the sliding columns 5 are opened on the retaining ring 1. The sliding columns 5 are slidably connected to the sliding through holes. A limiting platform 6 is connected to the end of the sliding column 5. The limiting platform 6 is located outside the retaining ring 1. A compression spring 7 is connected on the U-shaped frame 2. The other end of the compression spring 7 contacts the retaining ring 1. A connecting plate 8 is connected to the outer wall of the retaining ring 1. A slide rail is connected to the connecting plate 8. A vertical groove 9 matching the slide rail is opened on the frame 11. The slide rail is slidably connected to the groove 9.

[0014] like Figure 1 and Figure 3 As shown, the drive assembly includes a steel wire rope 12, one end of which is connected to a buckle 1, and the other end of which passes over a fixed pulley 10 and is connected to a winch 13. The fixed pulley 10 is fixedly installed on the frame 11. The surface of the grinding roller 3 is concave. A brake-type universal wheel (not shown in the figure) is installed on the bottom surface of the frame 11. The brake-type universal wheel can be a common universal wheel in the prior art, which will not be described in detail here.

[0015] During specific construction, such as Figures 1 to 4 As shown, the movable retaining ring 1 and the frame 11 are moved to the pier 14 to be constructed. Then, bolts are used to fasten the two retaining rings 1 onto the pier 14. Due to the action of the compression spring 7, the grinding roller 3 is always in contact with the surface of the pier 14. Finally, the winch 13 and the motor 4 are started, so that the movable retaining ring 1 rises while the grinding roller 3 rotates at high speed (the movable retaining ring 1 falls by its own weight) to carry out the base surface grinding operation. After the grinding is completed, the frame 11 can be rotated to other work positions to continue grinding. The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
