One side of the top of the bottom plate 1 is fixedly connected with a push rod 3, and the other side of the top of the bottom plate 1 is fixedly connected with a fixing plate 4. A motor 1 6 is fixedly installed on the top of the fixing plate 4.

[0031] A vertical groove 5 is opened inside the fixing plate 4. The output end of the motor 1 6 passes through the fixing plate 4 and is fixedly connected with a lead screw 7. The lead screw 7 is rotatably connected with the fixing plate 4.

[0032] A threaded sleeve 8 is sleeved outside the lead screw 7. One side of the threaded sleeve 8 is fixedly connected to a right rod 9. The right rod 9 is slidably connected to the vertical groove 5. One side of the right rod 9 away from the threaded sleeve 8 is fixedly connected to a mounting plate 10. In the middle of one side of the mounting plate 10, a second motor 11 is fixedly installed. The output end of the second motor 11 passes through the mounting plate 10 and is fixedly connected to a rotating shaft 12. One end of the rotating shaft 12 is fixedly connected to a cutting blade 13. A protective sleeve 14 is sleeved outside the cutting blade 13.

[0033] The lead screw 7 is located inside the vertical groove 5. The threaded sleeve 8 is threadedly connected to the lead screw 7. The rotating shaft 12 is rotatably connected to the mounting plate 10. The cutting blade 13 is located on the side of the rotating shaft 12 away from the mounting plate 10.

[0034] Among them, a sliding groove 15 is opened on one side of the mounting plate 10 close to the cutting blade 13. A sliding rod 17 is fixedly connected inside the sliding groove 15. One side of the protective sleeve 14 is fixedly connected to a slider 16. The slider 16 is slidably connected to the sliding rod 17. A first spring 18 is sleeved outside the sliding rod 17.

[0035] The sliding grooves 15 are symmetrically opened. The number of sliders 16 is the same as that of the sliding grooves 15. The top end of the first spring 18 is fixedly connected to the inner top surface of the sliding groove 15. The bottom end of the first spring 18 is fixedly connected to the top of the slider 16.

[0036] Among them, inclined blocks 19 are symmetrically and fixedly connected to the inner side of the sliding groove 15. Rotating rods 20 are symmetrically and rotatably installed on the outside of the slider 16. A telescopic rod 22 is slidably connected inside the rotating rod 20. The top end of the telescopic rod 22 is fixedly connected to a contact rod 23.

[0037] By setting the protective sleeve 14, the slider 16, the sliding rod 17, the first spring 18, the inclined block 19, the rotating rod 20 and the contact rod 23, in the initial state, the protective sleeve 14 is located outside the lower half of the cutting blade 13. When cutting work is carried out, the cutting blade 13 is moved to the cutting position of the concrete, the second motor 11 is started, the second motor 11 drives the rotating shaft 12 and the cutting blade 13 to rotate, the protective sleeve 14 abuts against the concrete, and then the first motor 6 is started.

The stop block 21 blocks the rotating rod 20, enabling the contact rod 23 to play a self-locking role, facilitating the more stable rise of the protective sleeve 14. When the protective sleeve 14 needs to descend, manual resetting can be performed. By covering and blocking the cutting disc 13 with the protective sleeve 14, the splashing of fragments during cutting is reduced, protecting the safety of the surrounding workers and solving the problem that there is no protective mechanism on the saw rope of the device, which is likely to cause the flying of cut gravel blocks and injure people during the operation of the concrete static cutting device, and there are certain defects.

[0039] The inclined blocks 19 are evenly arranged at equal distances. The rotating rod 20 is rotatably connected to the slider 16.

[0040] On the other side of the threaded sleeve 8 is fixedly connected a left rod 25. Fixed to the top of the base plate 1 is a positioning rod 26. The positioning rod 26 is located on one side of the fixing plate 4. The left rod 25 is slidably connected to the positioning rod 26. On the side of the left rod 25 away from the threaded sleeve 8 is fixedly connected an installation piece 27.

[0041] There are provided a left rod 25, an installation piece 27, a slot 28, a guide rod 29, a slide plate 30, a connecting block 31 and a pin 32. When the threaded sleeve 8 moves, it will also drive the left rod 25 and the installation piece 27 to move. When the position of the threaded sleeve 8 remains unchanged, the slide plate 30 can be pulled. The slide plate 30 drives the connecting block 31 and the pin 32 to move, making the position of the pin 32 correspond to the position of the slot 28, and then pressing the pin 32 into the slot 28 to facilitate the fixing of the installation piece 27 and the left rod 25, thereby assisting in the positioning of the threaded sleeve 8 and the installation plate 10 and improving the use stability of the device.

[0042] Symmetrically opened in the interior of the installation piece 27 are slots 28. Fixed to the top of the base plate 1 is a guide rod 29. The guide rod 29 is located on one side of the push rod 3. The outside of the guide rod 29 is slidably connected with a slide plate 30.

[0044] Working principle:

[0045] Before using this static cutting device for concrete structures, it is necessary to first check the overall condition of the device to ensure that it can work properly. According to Figure 1 - Figure 6 As shown, when performing the cutting work, move the cutting blade 13 to the cutting position of the concrete, start the second motor 11, the second motor 11 drives the rotating shaft 12 and the cutting blade 13 to rotate, the protective sleeve 14 abuts against the concrete, and then start the first motor 6. The first motor 6 drives the lead screw 7 to rotate, so that the threaded sleeve 8 drives the right rod 9 and the mounting plate 10 to descend, thereby facilitating the cutting into the concrete interior.

[0046] As the cutting blade 13 cuts into the interior of the concrete, the protective sleeve 14 rises relative to the cutting blade 13. The protective sleeve 14 drives the slider 16 to rise outside the slide bar 17 and compresses the first spring 18. The slider 16 drives the rotating rod 20 and the contact rod 23 to move. The contact rod 23 contracts under the extrusion of the inclined block 19. The contact rod 23 drives the telescopic rod 22 to slide into the rotating rod 20 and compresses the second spring 24. Until the contact rod 23 moves between the intervals of the inclined block 19, the second spring 24 drives the contact rod 23 to reset. The stop block 21 blocks the rotating rod 20, so that the contact rod 23 plays a self-locking role, facilitating the more stable rise of the protective sleeve 14. When the protective sleeve 14 needs to descend, manual reset can be performed. By covering and blocking the cutting blade 13 with the protective sleeve 14, the splashing of fragments during cutting is reduced.

[0047] When the threaded sleeve 8 moves, it will also drive the left rod 25 and the mounting piece 27 to move. When the position of the threaded sleeve 8 remains unchanged, the sliding plate 30 can be pulled. The sliding plate 30 drives the connecting block 31 and the pin 32 to move, so that the position of the pin 32 corresponds to the position of the slot 28. Then press the pin 32 into the slot 28 to facilitate the fixation of the mounting piece 27 and the left rod 25, thereby assisting the positioning of the threaded sleeve 8 and the mounting plate 10 and improving the use stability of the device.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
