[0021] Please refer to Figures 1-5 The present application provides a technical solution:

[0022] The cast steel roller rotating bracket comprises a bracket body 1 for supporting and rotating the roller, the bracket body 1 comprises a base 11, a moving part 12 and a roller 13, the moving part 12 is slidably connected to the top of the base 11, the roller 13 is rotatably installed in the moving part 12, a plurality of protective shells 2 with smooth surfaces are tightly attached to the outer side of the roller 13, a connecting plate 3 is fixedly connected to the outer side of the protective shell 2, a bolt 4 composed of a threaded rod and a nut is penetrated in the connecting plate 3, a positioning assembly 5 is arranged in the protective shell 2, the positioning assembly 5 comprises a positioning column 51, a groove 52, a sponge layer 53, a clamping block 54, an elastic block 55, a rubber block 56 and a through hole 57, the positioning column 51 is fixedly connected to the protective shell 2, the groove 52 is formed in the positioning column 51, the sponge layer 53 is arranged in the groove 52, the clamping block 54 in the shape of a hemisphere is fixedly connected to one end of the sponge layer 53, the rubber block 56 is fixedly connected to the other end of the sponge layer 53, a plurality of clamping grooves 6 are formed in one side of the roller 13, the detachable protective shell 2 is arranged, the whole replacement process of the roller 13 is avoided, and the purpose of saving resources is achieved by replacing only the protective shell 2, and the positioning effect is achieved when the protective shell 2 is installed through the arrangement of the positioning assembly 5.

[0023] The protective shell 2 is in inverted U-shaped cross section and is arranged in arc shape as a whole, and the partial connecting plates 3 are closely attached, facilitating the use of the protective shell 2; the rubber block 56 is fixedly connected with the groove 52 at the bottom, a plurality of uniformly distributed through holes 57 are formed in the rubber block 56, and the edge of the rubber block 56 is arranged in wave shape, facilitating the increase of the elasticity of the rubber block 56; the sponge layer 53 is provided with a plurality of uniformly distributed elastic blocks 55, and the elastic block 55 is hollow, facilitating the increase of the resilience of the sponge layer 53; the positioning column 51 is closely attached in the clamping groove 6, the two sides of the clamping groove 6 are arranged in arc protrusion, and the arc protrusion of the clamping groove 6 is closely attached with the clamping block 54, facilitating the simple fixing after the positioning column 51 is inserted.

[0024] Workflow: The equipment is powered on in the process of running, the cast steel roller rotating bracket is usually used in cooperation with two bracket bodies 1, the shaft head of the roller is simply fixed through the fixing assembly, the roller body is attached to the surface of the protective shell 2 outside the roller 13, the bracket body 1 is started to drive the roller 13 and the protective shell 2 to rotate, so as to drive the roller body to rotate, and the roller body is repaired and maintained. When the protective shell 2 is damaged and more serious due to long-term use and friction with the roller body, the protective shell 2 needs to be replaced. When the bracket body 1 is not in use, first, the bolts 4 on the front and rear sides of the protective shell 2 are sequentially rotated and removed, the rotating roller 13 is rotated, so as to facilitate the disassembly of all the bolts 4. After disassembly, the upper half of the protective shell 2 is moved obliquely upwards, driving the positioning column 51 to move in the clamping groove 6. In the moving process, the clamping block 54 arranged in hemispherical shape is extruded, driving the sponge layer 53 and the elastic blocks 55 inside the sponge layer 53 to be extruded. The elastic block 55 is hollow, effectively increasing the deformation amount of the elastic block 55. At the same time, the rubber block 56 is extruded. The through holes 57 formed in the rubber block 56 can increase the deformation amount of the rubber block 56. The rubber block 56 and the sponge layer 53 are used in cooperation, so that the clamping block 54 can be moved into the groove 52 after being extruded. Then, the protective shell 2 is continuously moved until the positioning column 51 completely leaves the clamping groove 6. In the same way, the remaining protective shell 2 is better disassembled by rotating the roller 13, so as to realize the disassembly of the seriously worn protective shell 2. Then, the positioning column 51 on one side of the new protective shell 2 is inserted into the clamping groove 6, and the clamping block 54 can be closely attached to the arc protrusion in the clamping groove 6 by popping out, so as to simply fix the installed protective shell 2. After replacing the remaining protective shell 2, the bolts 4 are penetrated through the connecting plates 3 and are fastened, so as to further fix the installed protective shell 2. The detachable protective shell 2 is arranged, avoiding the process of replacing the whole roller 13, and only replacing the protective shell 2 realizes the purpose of saving resources. The positioning assembly 5 is arranged, so that the protective shell 2 has positioning effect during installation.
