Description

Technical Field

[0001] This utility model relates to the field of cement precast slab processing, specifically a grooving device for cement precast slabs used in building construction. Background Technology

[0002] Precast slabs are floor slabs used in early 20th-century construction. They are modules or panels used in engineering projects. Therefore, cement precast slabs are required in the construction of houses. Since precast slabs are precast concrete components produced and processed in a prefabrication plant and then transported directly to the construction site for installation, they are called precast slabs. In the process of processing cement precast slabs, they need to be grooved according to requirements, so grooving equipment is required.

[0003] Existing precast concrete slab grooving equipment places the precast concrete slab on a workbench so that it can be cut by a cutting disc. At the same time, a water spraying component is installed to spray water onto the cutting disc to cool it down. However, the sprayed water carries a large amount of debris, and the water and debris flow into the water outlet pipe and are discharged directly through the outlet pipe. This makes it difficult to collect and recycle the sprayed water, resulting in a waste of water resources. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a grooving device for precast concrete slabs in building construction, so as to solve the technical problem that the water sprayed out when cooling the cutting disc is directly discharged through the drain pipe, thus causing water waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grooving device for precast concrete slabs in building construction, comprising a water storage tank, a water collection platform at the top of the water storage tank, a water trough inside the water collection platform, and a filter assembly inside the water trough. The filter assembly includes two pads inside the water trough, a fixed plate installed inside the water storage tank, and a worm gear installed inside the water storage tank via a sealed bearing. A filter screen is placed on the top of the two pads. A threaded column is connected to the top of the fixed plate via a bearing, and a threaded cylinder is sleeved on the outer wall of the threaded column. A worm wheel is installed below the outer wall of the threaded column. A top plate is installed at the top of the threaded cylinder. A guide rod penetrating the top plate and the filter screen is provided on one side of the top of the fixed plate. A placement frame is installed on the water collection platform via a support column.

[0006] By adopting the above technical solution, when the filter screen needs to be removed, the worm can be rotated. The rotation of the worm will drive the worm wheel to rotate, which in turn will drive the threaded column to rotate. The rotation of the threaded column will cause the threaded cylinder to move upward.

[0007] Furthermore, a vertical plate is installed on one side of the top of the water storage tank, and a first groove is opened on one side of the vertical plate. A first motor is installed on the outer surface of the vertical plate, and the output end of the first motor is connected to a first lead screw extending into the first groove. A first movable seat is sleeved on the outer wall of the first lead screw.

[0008] By adopting the above technical solution, when the first motor is working, it can drive the first lead screw to rotate, the first lead screw will drive the first movable seat to move, and the first movable seat will then drive the movable plate to move.

[0009] Furthermore, a movable plate is installed on one side of the first movable seat, and a horizontal plate is provided on one side of the movable plate, and a second motor is installed on one side of the horizontal plate.

[0010] By adopting the above technical solution, when the first movable seat moves, it will drive the movable plate to move, which in turn will drive the horizontal plate to move, and then drive the second motor to move.

[0011] Furthermore, a second groove is provided at the bottom of the horizontal plate, and the output end of the second motor is connected to a second lead screw extending into the second groove, and a second movable seat is sleeved on the outer wall of the second lead screw.

[0012] By adopting the above technical solution, when the second lead screw rotates, it will drive the second movable seat to move. After the second movable seat moves, it will drive the hydraulic cylinder to move, and then drive the mounting bracket to move.

[0013] Furthermore, a hydraulic cylinder is installed at the bottom of the second movable seat, and a mounting bracket is installed at the output end of the hydraulic cylinder via a piston rod.

[0014] By adopting the above technical solution, when it is necessary to adjust the height of the mounting bracket, the hydraulic cylinder can be activated to extend and retract the piston rod, thereby moving the mounting bracket to adjust its height.

[0015] Furthermore, a third motor is installed inside the mounting bracket, and the output end of the third motor is connected to a cutting disc.

[0016] By adopting the above technical solution, when it is necessary to groove the cement precast slab, the third motor can be started. The operation of the third motor can drive the cutting disc to rotate, and after the cutting disc rotates, the cement precast slab can be grooved.

[0017] Furthermore, a protective cover is installed on one side of the mounting bracket, and the cutting disc is located inside the protective cover.

[0018] By adopting the above technical solution, the protective cover can protect the cutting disc and prevent the upper part of the cutting disc from being directly exposed to the external environment.

[0019] Furthermore, a water guide pipe is installed at the bottom of the mounting bracket, and two water spray pipes extending into the interior of the protective cover are provided on the water guide pipe.

[0020] By adopting the above technical solution, when water enters the water guide pipe, it will flow into the spray pipe and then be sprayed out through the spray pipe onto the surface of the cutting disc to rinse and cool the cutting disc.

[0021] Furthermore, a water pump is installed inside the water storage tank. The water pump's inlet end is connected to a water pipe extending to the pump, and the water pump's outlet end is connected to a water delivery hose extending into the water guide pipe.

[0022] By adopting the above technical solution, the water pump can draw water from the water storage tank through the water pumping pipe, and the water is transported to the water delivery pipe through the water delivery hose.

[0023] Furthermore, a sliding rod is installed on one side of the vertical plate, and a sliding seat is sleeved on the outer wall of the sliding rod, with the top of the sliding seat connected to the bottom of the movable plate.

[0024] By adopting the above technical solution, when the movable plate moves, it will drive the slide block to slide on the slide rod, and the slide block can support the movable plate and improve the stability of the movable plate when it moves.

[0025] In summary, the present invention has the following main advantages:

[0026] This invention incorporates a filtration assembly. When water sprayed onto the cutting disc flows downwards, water and debris fall into the water tank. The filter screen filters the water, preventing debris from falling into the water storage tank, while the water flows into the storage tank for reuse, thus improving water recycling efficiency. After prolonged filtration, a significant amount of debris accumulates on the filter screen. To remove the filter screen, the operator rotates a worm gear, which in turn rotates a threaded cylinder. This rotation causes the threaded cylinder to move upwards, which in turn moves the top plate upwards. The top plate then pushes the filter screen upwards, removing it from the water tank. The operator can then remove the filter screen to clean the accumulated debris. This disassembly and assembly method is simple and convenient. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of this utility model will be described below based on its overall structure.

[0036] Example 1:

[0037] A type of grooving equipment for precast concrete slabs used in building construction, such as Figures 1-6 As shown, the system includes a water storage tank 1, with a water collection platform 24 on top. A water tank 25 is located inside the water collection platform 24, and a filter assembly 4 is installed inside the water tank 25. The filter assembly 4 includes two pads 401 inside the water tank 25, a fixing plate 407 installed inside the water storage tank 1, and a worm gear 409 installed inside the water storage tank 1 via a sealed bearing. A filter screen 402 is placed on top of the two pads 401. A threaded column 406 is connected to the top of the fixing plate 407 via a bearing. A threaded cylinder 405 is fitted onto the outer wall of the threaded column 406, and a worm wheel 408 is installed below the outer wall of the threaded column 406. The worm wheel 408 meshes with the worm gear 409 so that when the worm gear 409 rotates, it drives the worm wheel 408 to rotate, which in turn drives the threaded column 406 to rotate, thereby causing the threaded cylinder 405 to move upwards. One end of the worm gear 409 extends to the outside of the water storage tank 1 and is connected to a turntable.

[0038] Specifically, a top plate 404 is installed at the top of the threaded cylinder 405. A guide rod 403 is provided on one side of the top of the fixing plate 407, which passes through the top plate 404 and the filter screen 402. When the filter screen 402 needs to be removed, the worm gear 409 can be rotated. After the worm gear 409 rotates, it will drive the worm wheel 408 to rotate, which in turn drives the threaded column 406 to rotate. After the threaded column 406 rotates, the threaded cylinder 405 will move upward. A placement rack 23 is installed on the water collection platform 24 through the support column. The thickness of the filter screen 402 is less than the distance between the placement rack 23 and the water collection platform 24, so that the staff can easily remove the filter screen 402 to clean the debris accumulated on the filter screen 402. The top of the top plate 404 contacts the bottom of the filter screen 402 to support the filter screen 402. The filter screen 402 is detached from the water collection platform 24.

[0039] Specifically, a vertical plate 5 is installed on one side of the top of the water storage tank 1, and a first groove 6 is provided on one side of the vertical plate 5. A first motor 7 is installed on the outer surface of the vertical plate 5. The output end of the first motor 7 is connected to a first lead screw 9 extending into the first groove 6. A first movable seat 8 is sleeved on the outer wall of the first lead screw 9. When the first motor 7 is working, it can drive the first lead screw 9 to rotate. The first lead screw 9 will drive the first movable seat 8 to move. The first movable seat 8 will then drive the movable plate 10 to move. A movable plate 10 is installed on one side of the first movable seat 8, and a horizontal plate 11 is provided on one side of the movable plate 10. A second motor 15 is installed on one side of the horizontal plate 11. When the first movable seat 8 moves, it will drive the movable plate 10 to move. The movable plate 10 will drive the horizontal plate 11 to move, and then drive the second motor 15 to move.

[0040] See Figures 1-4 A second groove 12 is provided at the bottom of the horizontal plate 11. The output end of the second motor 15 is connected to a second lead screw 14 extending into the second groove 12. A second movable seat 13 is sleeved on the outer wall of the second lead screw 14. When the second lead screw 14 rotates, it will drive the second movable seat 13 to move. After the second movable seat 13 moves, it will drive the hydraulic cylinder 16 to move, and drive the mounting bracket 17 to move. The first movable seat 8 is threadedly connected to the first lead screw 9, and the second movable seat 13 is threadedly connected to the second lead screw 14. The hydraulic cylinder 16 is installed at the bottom of the second movable seat 13. The output end of the hydraulic cylinder 16 is mounted on a mounting bracket 17 via a piston rod. When the height of the mounting bracket 17 needs to be adjusted, the hydraulic cylinder 16 can be activated to extend and retract the piston rod, thereby moving the mounting bracket 17 to adjust its height. A third motor 18 is installed inside the mounting bracket 17. The output end of the third motor 18 is connected to a cutting disc 20. When it is necessary to groove the precast concrete slab, the third motor 18 can be activated. The operation of the third motor 18 can drive the cutting disc 20 to rotate, and the cutting disc 20 can then perform grooving on the precast concrete slab.

[0041] Example 2:

[0042] Based on the above embodiment 1, since the cutting disc 20 generates heat when cutting the precast slab, the following structure is set up to cool down the cutting disc 20.

[0043] See Figures 1-4 A water guide pipe 21 is installed at the bottom of the mounting bracket 17. Two water spray pipes 22 are provided on the water guide pipe 21, extending into the protective cover 19. When water enters the water guide pipe 21, it flows into the water spray pipes 22 and is then sprayed out onto the surface of the cutting disc 20 to rinse and cool it. A water pump 2 is installed inside the water storage tank 1. The inlet of the water pump 2 is connected to a water suction pipe, and the outlet of the water pump 2 is connected to a water delivery hose extending into the water guide pipe 21. 3. When the water pump 2 is working, it can draw water from the water storage tank 1 through the water pumping pipe. The water is transported to the water guide pipe 21 through the water delivery hose 3. The top side of the water storage tank 1 is also connected to the water inlet pipe 28. The bottom side of the water storage tank 1 is connected to the drain valve so that cold water can be added into the water storage tank 1 through the water inlet pipe 28. When it is necessary to drain the water in the water storage tank 1 for water replacement, the drain valve can be opened to drain the water. After draining, the drain valve is closed, and then cold water is added into the water storage tank 1 through the water inlet pipe 28.

[0044] Example 3:

[0045] Based on the above embodiment 1, the following structure will be set to protect the cutting disc 20.

[0046] See Figures 1-3 A protective cover 19 is installed on one side of the mounting bracket 17. The cutting disc 20 is located inside the protective cover 19. The protective cover 19 can protect the cutting disc 20 and prevent the upper part of the cutting disc 20 from being directly exposed to the external environment.

[0047] Example 4:

[0048] Based on the above embodiment 1, since the first lead screw 9 will drive the first movable seat 8 to move when it rotates, and then drive the movable plate 10 to move, the following structure will be set to improve the stability of the movable plate 10 when it moves.

[0049] See Figures 1-3 A slide bar 26 is also installed on one side of the vertical plate 5, and a slide seat 27 is sleeved on the outer wall of the slide bar 26. The top of the slide seat 27 is connected to the bottom of the movable plate 10. When the movable plate 10 moves, it will drive the slide seat 27 to slide on the slide bar 26. The slide seat 27 can support the movable plate 10 and improve the stability of the movable plate 10 when it moves.

[0050] The working principle of this utility model is as follows: First, the operator can install the grooving equipment and connect the power supply. Then, the cement precast slab is placed on the placement rack 23. Then, the grooving position is adjusted. The adjustment process is to start the second motor 15. The second motor 15 can drive the second lead screw 14 to rotate, which in turn drives the second movable seat 13 to move, then drives the hydraulic cylinder 16 to move, and then drives the cutting disc 20 to move, so as to adjust the position of the cutting disc 20.

[0051] After adjustment, the second motor 15 is turned off and the hydraulic cylinder 16 and the third motor 18 are started. The hydraulic cylinder 16 extends the piston rod, which in turn moves the mounting bracket 17 downward. The mounting bracket 17 then moves the third motor 18 and the cutting disc 20 downward. The third motor 18 drives the cutting disc 20 to rotate, so that the cutting disc 20 can groove the precast concrete slab. During grooving, the water pump 2 and the first motor 7 are started simultaneously. The first motor 7 drives the first lead screw 9 to rotate, which in turn moves the first movable seat 8. The movement of the movable plate 10, in turn, causes the horizontal plate 11 to move, which in turn causes the slide block 27 to move on the slide rod 26. The movement of the horizontal plate 11 causes the cutting disc 20 to move, which facilitates grooving of the precast concrete slab. At the same time, the water pump 2 works to draw water from the water storage tank 1 through the water pumping pipe. The water is then transported through the water delivery hose 3 to the water guide pipe 21, and then flows into the water spray pipe 22. The water is then sprayed out through the water spray pipe 22 and onto the surface of the cutting disc 20 to rinse and cool the cutting disc 20.

[0052] The sprayed water and debris generated during the grooving process flow into the water tank 25. The filter screen 402 filters the water, preventing debris from falling into the water storage tank 1, while the water can flow into the water storage tank 1 for reuse, thus improving the efficiency of water recycling. After the filter screen 402 has been filtering water for a long time, a lot of debris will accumulate on its surface. At this time, the filter screen 402 needs to be removed. The operator can rotate the worm gear 409, which will drive the worm wheel 408 to rotate, which in turn drives the threaded column 406 to rotate. The rotation of the threaded column 406 will cause the threaded cylinder 405 to move upward, which in turn drives the top plate 404 to move upward. The top plate 404 pushes the filter screen 402 upward, so that the filter screen 402 is removed from the water tank 25. Then the operator can remove the filter screen 402 to clean the debris accumulated on it.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
