Description

Technical Field

[0001] This utility model relates to the field of prefabricated component cutting technology, specifically a prefabricated PC exterior wall cutting device. Background Technology

[0002] The biggest difference between factory prefabrication and on-site assembly and traditional construction is that construction projects can now be manufactured in batches in factory workshops. The prefabricated components are simply transported to the construction site and assembled according to the drawings. This not only shortens the construction period to the greatest extent, but also reduces the risks of working at heights, lowers costs, and reduces environmental and noise pollution.

[0003] A search revealed a cement concrete precast component cutting device (publication number CN220840954U), relating to the field of precast component cutting technology. The device includes a base, an L-shaped cutting table fixed to the upper end of the base, a pushing mechanism mounted on the vertical end of the L-shaped cutting table, a U-shaped frame mounted on one side of the horizontal section of the L-shaped cutting table, a fixing component mounted in the middle of the bottom of the horizontal section of the U-shaped frame, a moving component mounted on one side of the bottom of the horizontal section of the U-shaped frame, a cutting component mounted on the moving component, a waste recycling and crushing mechanism mounted on the side wall of the L-shaped cutting table, and a dust suppression component mounted on the upper end of the U-shaped frame. In this invention, the coordinated use of the pushing mechanism, fixing component, moving component, cutting component, and waste recycling and crushing mechanism directly crushes the cut-off scrap, thereby reducing the space occupied by scrap, facilitating cleanup, avoiding obstruction of subsequent precast component cutting, eliminating the need for laborious scrap handling, and improving work efficiency.

[0004] When the aforementioned device cuts the wall panel, the cut-off scraps fall into the crushing mechanism as a whole. Since the scraps are quite heavy, they can be damaged if they fall directly into the crushing mechanism. Furthermore, the scraps cannot be crushed until the cutting is completely finished.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0034] Please see Figure 1-4 As shown, this utility model is a precast PC exterior wall cutting device, comprising:

[0035] A base plate 100 is fixedly connected to the top of the base plate 100, and a fixing frame 120 is fixedly connected to the top of the cutting table 110.

[0036] The cutting mechanism includes a first hydraulic rod 210, a push plate 220, a first cutting device 230, a second hydraulic rod 240, a segmentation assembly 250, a slope plate 260, and a crushing box 270.

[0037] The first hydraulic rod 210 is fixedly connected to the side wall of the cutting table 110, and the push plate 220 is fixedly connected to the telescopic end of the first hydraulic rod 210; the first cutting device 230 is fixedly installed in the middle of the cutting table 110; the second hydraulic rod 240 is fixedly connected to one side of the top surface of the fixing frame 120; the segmented assembly 250 is fixedly connected to the telescopic end of the second hydraulic rod 240; the slope plate 260 is fixedly connected to the side wall of the cutting table 110; and the crushing box 270 is fixedly connected to the base plate 100. The first cutting device 230 is an existing structure and will not be described further. The crushing device inside 270 is an existing structure and will not be described further. The first hydraulic rod 210 drives the push plate 220 to move and push the wall panel to move on the cutting table 110 and be cut by the first cutting device 230. The second hydraulic rod 240 drives the segmenting assembly 250 to move up and down, so that the segmenting assembly 250 cuts the waste into small segments. The slide plate 260 slides the cut waste into the crushing box 270, preventing the whole waste from falling directly into the crushing box 270. At the same time, the waste is cut into small segments and crushed while being cut, which improves the crushing efficiency.

[0038] The segmented assembly 250 includes a mounting plate 251, a first motor 252, a sliding groove 253, a guide screw 254, a threaded post 255, and a second cutting device 256;

[0039] Mounting plate 251 is fixedly connected to the telescopic end of second hydraulic rod 240. First motor 252 is fixedly connected to the side wall of mounting plate 251. Sliding groove 253 is opened on the bottom surface of mounting plate 251. Guide screw 254 is rotatably connected in sliding groove 253. Guide screw 254 is fixedly connected to the power output end of first motor 252. Threaded column 255 is threadedly connected to guide screw 254. Second cutting device 256 is fixedly connected to the bottom of threaded column 255. First motor 252 provides power to drive guide screw 254 to rotate. Threaded column 255 has a threaded hole in the middle that is threadedly connected to guide screw 254. The size of threaded column 255 is the same as the size of sliding groove 253, so that the rotation of guide screw 254 drives threaded column 255 to slide in sliding groove 253. Threaded column 255 drives second cutting device 256 to slide, cutting scrap into small segments. Second cutting device 256 has the same structure as first cutting device 230.

[0040] A rotating door 271 is rotatably connected to the surface of the crushing box 270. A handle 272 is fixedly connected to the surface of the rotating door 271. A limit hook 273 is fixedly connected to the edge of the rotating door 271. A rotating pin 274 is rotatably connected to the side wall of the crushing box 270. The rotating door 271 opens and closes to open the crushing box 270 for easy cleaning. The groove of the limit hook 273 has the same thickness as the rotating pin 274. After the rotating pin 274 rotates, it gets stuck in the groove of the limit hook 273, which locks the rotating door 271 and closes the crushing box 270.

[0041] A column 310 is fixedly connected to the other side of the base plate 100. A conveyor belt 320 is fixedly connected between the columns 310. The surface of the conveyor belt 320 is flush with the surface of the cutting table 110. After the wall panel is cut, it is pushed onto the conveyor belt 320 and then conveyed to the next stage by the conveyor belt 320.

[0042] A water inlet pipe 410 is fixedly connected to the top of the fixed frame 120, and a water delivery pipe 420 is fixedly connected to the bottom of the water inlet pipe 410. Spray nozzles 430 are fixedly connected at equal intervals to the bottom end of the water delivery pipe 420. The water inlet pipe 410 is connected to an external water source, and the water inlet pipe 410 transmits water into the water delivery pipe 420. The water is then transmitted to each spray nozzle 430 through the water delivery pipe 420 and sprayed out, thereby reducing cutting dust.

[0043] Working principle: The wall panel is placed on the cutting table 110. The first hydraulic rod 210 drives the push plate 220 to move, and the push plate 220 pushes the wall panel to be cut by the first cutting device 230. The second hydraulic rod 240 drives the segmenting assembly 250 to descend and contact the cut waste material. Then, the first motor 252 is started to drive the guide screw 254 to rotate. The guide screw 254 drives the threaded column 255 to move, and the threaded column 255 drives the second cutting device 256 to move to cut the waste material into small segments. The small segments of waste material slide into the crushing box 270 through the slide plate 260 and are crushed by the crushing rollers inside the crushing box 270, thereby preventing the whole piece of waste material from being crushed. The material falls directly from the cutting table 110 into the crushing box 270, which deforms the blades of the crushing rollers in the crushing box 270. At the same time, it is not necessary to wait for the wall panel to be completely cut before crushing the corner waste, thus improving the crushing efficiency. The cut wall panel is pushed onto the conveyor belt 320 and then conveyed to the next stage. Water is sent into the water inlet pipe 410 and then sprayed out from the nozzle 430 to reduce the cutting dust. After the rotating pin 274 is rotated out of the slot of the limit hook 273, the handle 272 is pulled to drive the rotating door 271 to rotate and open, so as to clean out the debris at the bottom of the crushing box 270.

[0044] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0045] The adjustment mechanism includes a second motor 510, a short slide 520, a short lead screw 530, a sliding column 540, and a baffle 550.

[0046] The second motor 510 is fixedly connected to the side wall of the cutting table 110. The short slide groove 520 is opened on one side of the surface of the cutting table 110. The short lead screw 530 is fixedly connected to the power output end of the second motor 510 and rotatably connected in the short slide groove 520. The sliding column 540 is threadedly connected to the short lead screw 530 and slidably connected in the short slide groove 520. The baffle 550 is fixedly connected to the top surface of the sliding column 540. The second motor 510 provides power to drive the short lead screw 530 to rotate. The sliding column 540 has a thread in the middle and is threadedly connected to the short lead screw 530. The sliding column 540 and the short slide groove 520 are the same size, so that the rotation of the short lead screw 530 drives the sliding column 540 to slide in the short slide groove 520. The sliding column 540 drives the baffle 550 to slide, thereby clamping one side of the wall panel according to the required cutting width.

[0047] The adjustment mechanism also includes a long slide 560 and a long lead screw 570;

[0048] A long slide groove 560 is formed on the other side of the surface of the cutting table 110. A long lead screw 570 is rotatably connected in the long slide groove 560. Another second motor 510 is fixedly connected to the other side of the cutting table 110. The power output end of the other second motor 510 is fixedly connected to the end of the long lead screw 570. Another long slide groove 560 is threadedly connected to the long lead screw 570 and slidably connected in the long slide groove 560. The other second motor 510 provides power to drive the long lead screw 570 to rotate. The cross-sectional dimensions of the long slide groove 560 are the same as those of the short slide groove 520. The diameters of the long lead screw 570 and the short lead screw 530 are the same. The rotation of the long lead screw 570 drives another sliding column 540 to slide in the long slide groove 560. The sliding column 540 drives another baffle 550 to clamp the other side of the wall panel, so that the push plate 220 pushes the wall panel in a straight line to prevent deviation and cause cutting deviation.

[0049] Working principle: Based on the cutting width of the wall panel, a second motor 510 is started to drive the short lead screw 530 to rotate. The short lead screw 530 drives the sliding column 540 to slide in the short slide groove 520. The sliding column 540 drives the baffle 550 to move and clamp one side of the wall panel. Then, another second motor 510 is started to drive the long lead screw 570 to rotate. The long lead screw 570 drives another sliding column 540 to slide in the long slide groove 560. The other sliding column 540 drives another long slide groove 560 to move and clamp the other side of the wall panel. This ensures that the push plate 220 pushes the wall panel in a straight line, preventing deviation and causing cutting errors.
