Description

TECHNICAL FIELD

[0001] The utility model relates to a wide and thick plate surface polishing equipment with a protection mechanism. BACKGROUND

[0002] Wide and thick plates have the following features: large and heavy, such as a steel plate with an outer dimension of 13000mm*4900mm*50mm, which weighs up to 25t. Wide and thick plates refer to rolling mills with a width of more than 2800mm, and the widest can be up to 5500mm. The existing wide and thick plates are polished on the surface by a polisher during processing, which facilitates subsequent processing of the wide and thick plates.

[0003] The current polishing equipment relies on clamps to fix the upper and lower surfaces of the wide and thick plate during operation and polish the surface. However, the area tightly clamped by the clamp cannot be touched by the polishing device, resulting in that these clamped areas cannot be properly polished. This directly leads to incomplete polishing of the entire wide and thick plate, which further weakens the polishing efficiency and effect of the polishing equipment. SUMMARY

[0004] This section aims to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the utility model name to avoid obscuring the purpose of this section, the abstract of the specification and the utility model name.

[0025] Referring to Figs. 1-3 For one embodiment of the present application, a wide and thick plate surface polishing equipment with a protection mechanism is provided, which comprises a main unit 100, a clamping unit 200 and a polishing unit 300.

[0026] The main unit 100 comprises a U-shaped seat 101 and a roller 102 matched and installed with the U-shaped seat 101. The roller 102 is symmetrically arranged in the inner cavity of the U-shaped seat 101, and the outer surface of the roller 102 is sleeved with a conveying belt 103. The conveying belt 103 moves the position of the wide and thick plate. The U-shaped seat 101 can block the flying sparks, debris and the like, and protect the safety of the operator.

[0027] The clamping unit 200 comprises two air cylinders 201 fixedly installed on both sides of the U-shaped seat 101, the telescopic ends of the two groups of air cylinders 201 are fixedly installed with connecting plates 202, the top ends of the two groups of connecting plates 202 are provided with first transmission wheels 206, second transmission wheels 207 and third transmission wheels 208, the outer surfaces of the first transmission wheels 206 and the second transmission wheels 207 are sleeved with first transmission belts 209, the outer surfaces of the second transmission wheels 207 and the third transmission wheels 208 are sleeved with second transmission belts 210, one side of each of the two groups of connecting plates 202 close to the conveying belt 103 is installed with three connecting blocks 205, one side of each connecting block 205 is rotatably connected with a rotating rod 211, the bottom end of each rotating rod 211 is fixedly installed with a rotating roller 212, the top ends of the three rotating rods 211 are fixedly connected with the bottom ends of the first transmission wheels 206, the second transmission wheels 207 and the third transmission wheels 208 respectively, and the top end of each rotating roller 212 is provided with a driving structure. When the two groups of air cylinders 201 are started, they respectively drive a group of connecting plates 202 to move towards the direction of the wide and thick plate, so that the rotating rollers 212 installed on the connecting plates 202 can clamp the side wall of the wide and thick plate.

These first transmission wheels 206 further transmit power through the respective first transmission belts 209 to drive the second transmission wheels 207 to rotate. Subsequently, the second transmission wheels 207 further drive the third transmission wheels 208 to rotate through the second transmission belts 210. This transmission process finally enables the rotating rollers 212 located on the left and right sides of the wide and thick plate to rotate in the counterclockwise and clockwise directions respectively, thereby realizing effective transportation of the wide and thick plate.
