Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, in particular to a cutting device for twisted steel of a steel grating plate. Background Art

[0002] Steel grating is also called steel grid. It is a kind of steel product made of flat steel arranged crosswise at a certain spacing and crossbars, and welded into a square grid in the middle. It is mainly used for ditch covers, steel structure platform plates, steel ladder treads, etc. The crossbars are generally made of twisted square steel. Steel grating can be divided into twisted steel grating and plug-in steel grating according to its structure and connection method. Twisted steel grating is lighter than plug-in steel grating, and is suitable for occasions where the structural load needs to be reduced. Due to the structural characteristics of twisted steel grating, its light transmission performance is better, and it is suitable for places that require good lighting.

[0017] like Figure 3As shown, the height adjustment mechanism includes two symmetrical support plates 14 fixedly mounted on the rear surface of the rotating plate 11, and the rotating plate 11 is mounted on one side of the upper end of the base plate 17 through the support plates 14. A rotating round rod 18 is provided at the lower end of the support plate 14, and a locking nut 19 is provided at the lower end of the rotating round rod 18.

The rotating plate 11 is rotatably mounted on one end of the base plate 17 through the support plates 14. When the cutting angle needs to be adjusted, the rotating crank 20 drives the threaded rod 9 to rotate, thereby driving the rotating plate 11 to move up and down, thereby realizing the head cutting operation of twisted steel at different angles.

[0018] like Figure 4-Figure 5 As shown, the cutting mechanism includes a driving motor 4 fixedly mounted on the upper end of a mounting plate 10, a connecting platform 12 is fixedly mounted on one side surface of a rotating plate 11, an arc-shaped cutting blade 13 is provided at the lower end of the front surface of the connecting platform 12, a rotating locking rod 16 is provided at the rear end of the arc-shaped cutting blade 13, and a driving belt 15 is provided on the outer surface of the rotating locking rod 16 and the output end of the driving motor 4. Due to the annular structure in the steel grille, it is impossible to perform annular cutting using a conventional flat cutting blade, and the arc-shaped cutting blade 13 is used to rotate with the vehicle body 1 to realize the cutting operation of the annular grille 5.

[0019] like Figure 6 As shown, the distance adjustment fixing mechanism includes a plurality of through slots 102 equidistantly provided on the upper surface of the distance adjustment plate 101, a limit pin 108 is provided at the upper end of the through slot 102, a fixed truncated table 103 is provided at the lower end of the distance adjustment plate 101, a plug post 105 is provided at the center position of the upper surface of the fixed truncated table 103, and clamping plates 104 are fixedly installed on both sides of the plug post 105 on the upper surface of the fixed truncated table 103, and a bidirectional screw 109 is rotatably installed inside each clamping plate 104. The bidirectional screw 109 is rotated by using an external tool to drive the moving blocks 107 on both sides to expand and move outward respectively. The two moving blocks 107 are connected by a limit rod 106, and when they are away from each other, they are tightly attached to the inner circle of the annular grille 5, thereby realizing the fixation of the vehicle body 1 and the fixed truncated table 103.

[0020] The fixed truncated table 103 is provided with moving blocks 107 at the front and rear ends. Each moving block 107 is provided with connecting blocks 110 on both sides of the upper surface. Each moving block 107 is fixedly installed with two limiting rods 106 on the surface of one side close to the fixed truncated table 103 .

The handle 304 is rotated according to the cutting angle to drive the universal wheel 305, and the handle 304 is fixed by the T-shaped plug-in 303, so as to avoid deviation during the surrounding cutting process, which causes cutting errors.

[0022] like Figure 8 As shown, the dust collection mechanism includes a toothed disc 202 fixedly installed at the center position inside the dust box 201, a rotating motor 205 is provided on one side of the lower end of the dust box 201, and a threaded rotating rod 204 is provided at the output end of the rotating motor 205 passing through the dust box 201, and the threaded rotating rod 204 is meshed with the toothed disc 202.

[0023] A discharge channel 206 is provided at the lower end of the dust box 201, and three scraping teeth 203 arranged at equal angles are provided on one side surface of the toothed disc 202. The scraping teeth 203 fit the inner wall of the dust box 201, and a locking seat 207 is installed through the outer surface of the dust box 201. A dust baffle 208 is fixedly installed at one end of the dust box 201. The dust baffle 208 is located on the outer side of the arc-shaped cutting blade 13, and the sparks and metal debris generated when the arc-shaped cutting blade 13 is cut are collected. After the debris falls into the dust box 201, the threaded rotating rod 204 is driven by the rotating motor 205. The threaded rotating rod 204 is engaged with the toothed disc 202 to drive the scraping teeth 203 to clean the inner wall.

[0024] Working principle: According to the inner and outer radii of the annular grille 5, the operator adjusts the position of the fixed truncated table 103 at the lower end of the distance adjusting plate 101. After the column 105 is inserted into the distance adjusting plate 101, the limit pin 108 is used to fix the distance between the fixed truncated table 103 and the vehicle body 1. The bidirectional screws 109 on both sides are rotated to drive the moving block 107 to move outward. After the moving is limited by the limit rod 106, the moving block 107 is close to the inner circle of the annular grille 5, thereby achieving the position fixation of the annular grille 5.

[0025] According to the angle of the twisted steel at the upper end of the annular grille 5, the operator controls the crank 20 to drive the threaded rod 9 to rotate, and the connecting rod 8 rotatably installed at the upper end of the rotating plate 11 is threadedly matched with the threaded rod 9, and one side of the rotating plate 11 moves upward after being pulled. A cutting mechanism for cutting is set at the upper end of the mounting plate 10, and a connecting platform 12 is fixedly installed on the surface of the rotating plate 11 close to the spacing plate 101. The lower end of the outer surface of the connecting platform 12 is provided with an arc-shaped cutting blade 13, and the rear end of the arc-shaped cutting blade 13 is provided with a rotating lock rod 16. The rotating lock rod 16 and the output end of the driving motor 4 are both penetrated through the connecting platform 12 and are sleeved with a driving belt 15.

[0026] After determining the cutting angle, the handle 304 is rotated to drive the universal wheel 305 at the lower end, and the T-shaped plug-in 303 is inserted into the slot 302 to fix the angle of the universal wheel 305. A large amount of sparks and metal debris are generated during cutting, and the splashing may cause harm to the operator. The rotating motor 205 is activated during cutting, and the rotating motor 205 drives the threaded rotating rod 204 to drive the meshing toothed disc 202. After the metal debris is guided to the inside of the dust collecting box 201 by the dust baffle plate 208, it may remain on the inner wall of the dust collecting box 201. Long-term use will cause blockage and affect the collection effect. When the toothed disc 202 rotates, the three scraping teeth 203 arranged at equal angles fixedly mounted on the surface rotate accordingly. The scraping teeth 203 are attached to the inner wall of the dust collecting box 201, and after being transported downward, they are collected by the threaded rotating rod 204 and discharged through the discharge channel 206.

[0027] After determining the cutting angle and the inner and outer circle radii of the annular grille 5 , the handrail 3 is pushed to drive the vehicle body 1 to rotate along the annular grille 5 , thereby realizing the cutting operation of the redundant twisted steel on the outer circle of the annular grille 5 .

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
