Description

Technical Field

[0001] The present application relates to the technical field of trash racks, and in particular to a trash rack with a limited position in a rolling manner. Background Art

[0002] Trash rack (also called trash fence or trash net) is a device used in water conservancy projects, sewage treatment and hydropower stations to intercept and remove debris, floating objects and solid waste in the water flow to prevent them from entering the subsequent treatment or power generation equipment and protect the normal operation of the equipment. The concrete on both sides of the trash rack usually has installation grooves, and the frame of the trash rack can be inserted into the installation groove from top to bottom to complete the installation of the trash rack.

[0003] However, when the width of the trash rack frame is smaller than the width of the installation slot, the trash rack may shake significantly during operation. Therefore, it is necessary to install a fixing block on the frame of the trash rack. The fixing block is adapted to the installation slot. When hoisting, the fixing block is aligned with the installation slot and the trash rack is vertically hoisted from top to bottom. The fixing block and the frame are both inserted into the installation slot. The fixing block plays a limiting role, thereby preventing the trash rack from shaking significantly during use.

[0004] However, since the side wall of the installation groove is usually made of concrete, the peripheral surface of the fixing block will rub against the installation groove during the hanging process, which may easily cause the concrete surface or the fixing block to wear, thereby causing a gap between the fixing block and the installation groove, causing the trash rack to still shake during use;

[0005] Therefore, angle steels are embedded in advance before pouring concrete on both sides of the trash rack, and the inner wall of the angle steel is used as the inner wall of the installation groove. The setting of the angle steel can reduce friction, but the construction quality of the embedded angle steel is difficult to control. The angle steel is prone to displacement during the pouring and vibrating of concrete, resulting in displacement of the angle steel. At the same time, there is still sliding friction between the fixed block and the angle steel, and the friction force is still relatively large. Therefore, the limiting structure of the traditional trash rack has a large friction with the installation groove, which makes construction and installation difficult. Utility Model Content

[0006] In order to reduce the friction between the limiting structure of the trash rack and the installation groove, facilitate the hoisting of the trash rack, facilitate the construction and improve the construction efficiency, the present application provides a trash rack with a rolling limiting structure.

The top wall and the bottom wall of the first movable opening 21 are both set as first curved surfaces 211. The circumferential surface of the roller 3 can fit with the first curved surface 211, and the two side walls of the first movable opening 21 are gap-matched with the roller 3.

[0043] The second movable opening 22 is a circular opening, and the end of the drum 3 is opposite to the second movable opening 22. Balls 4 are arranged at both ends of the shell 2. One side of the ball 4 extends out of the second movable opening 22, and the other side of the ball 4 extends into the drum 3. The inner wall of the second movable opening 22 is set as a second arc surface 221, and the ball 4 can fit the second arc surface 221.

[0044] like Figure 4 The inner walls at both ends of the drum 3 are set as conical surfaces 31, the ball 4 remains tangent to the conical surface 31 along a generatrix of the conical surface 31, and the ball 4 can fit the second arc surface 221, and the ball 4 forms a clearance fit with the drum 3 and the second movable opening 22.

[0045] like Figure 2 and Figure 3The housing 2 comprises an upper shell 23 and a lower shell 24.
