Description
Technical Field
[0001] This utility model relates to the field of road surface cutting technology, and in particular to a road repair cutting device. Background Technology
[0002] Road cutting devices are mechanical equipment specifically designed for cutting operations during road construction and maintenance. They are mainly used for cutting asphalt pavements, concrete pavements, or other hard materials. Through their efficient cutting function, they can provide precise cutting lines for road repair, expansion, or new construction. These devices are typically equipped with high-strength cutting blades, power systems (such as motors or engines), and have functions such as depth adjustment, dust removal, and noise reduction, making them suitable for various construction environments.
[0003] Existing road cutting devices require manual lifting and slow lowering to the ground, which is cumbersome and inefficient. In addition, the debris and potentially broken circular saw blades generated during cutting can easily fly out, posing a safety threat to people in the vicinity.
[0004] Therefore, to address the issues of existing road cutting devices requiring manual lifting and slow lowering to the ground, which is cumbersome and inefficient, and the potential for debris and broken circular saw blades to fly off during cutting, posing a safety threat to surrounding personnel, an improved road cutting device can be designed. This improved device employs vertical lifting and cutting, and a microcontroller can precisely control the distance between the blade and the ground, improving operational efficiency and reducing manual labor intensity. Furthermore, the vertical cutting structure prevents flying debris from injuring people, effectively enhancing safety. Utility Model Content
[0005] To overcome the problems of existing road cutting devices, which require manual lifting and slow lowering to the ground during use, which is cumbersome and inefficient, and where debris and potentially broken circular saw blades can easily fly out during cutting, posing a safety threat to people in the surrounding area.
[0006] The technical solution of this utility model is as follows: a road cutting device, including a housing; and a lifting assembly. The lifting assembly is provided on the top of the housing and inside the housing. The lifting assembly includes a top plate, a limiting frame, a motor, a lead screw, a lifting block, a cutting machine, and a microcontroller. The housing is rectangular. The top of the housing is connected to the top plate. The lower inside of the housing is connected to the limiting frame. The top right side of the top plate is connected to the motor. The output end of the motor extends into the housing and is connected to the lead screw. The lead screw is connected to the limiting frame in a transmission connection. The outer end of the lead screw is threadedly connected to the lifting block. The lifting block is slidably connected to the housing. The left end of the lifting block is connected to the cutting machine. The front end of the housing is connected to the microcontroller. The microcontroller is electrically connected to the motor and the cutting machine. The cutting machine is slidably connected to the housing.
[0007] Preferably, by setting up a lifting component, the motor is started and stopped by a single-chip microcomputer. The motor drives the lead screw to rotate on the limit frame, thereby causing the lead screw to drive the lifting block to slide inside the housing. The movement of the lifting block causes the cutting machine to move on the housing, thereby pressing down the cutting machine. According to the settings of the single-chip microcomputer, the descent distance can be set to achieve precise adjustment. The housing can cover the cutting machine to prevent the waste chips from the cutting machine from flying away, and also to prevent the saw blade from breaking and flying out, thus improving safety. In the process of using existing road repair cutting devices, it is necessary to manually lift the device and slowly lower it to the ground, which is cumbersome and inefficient. In addition, the debris generated during cutting and the potentially broken circular saw blade are easy to fly away, posing a safety threat to the surrounding personnel.
[0008] Preferably, auxiliary blocks are connected to the lower sides of the front and rear ends of the housing, and two auxiliary blocks are provided.
[0009] Preferably, the auxiliary block has a triangular block connected to the end away from the shell, and the bottom of the auxiliary block has two movable wheels that are symmetrically connected to its vertical center line.
[0010] Preferably, the device has four casters, a water tank is connected to the right end of the housing, and a water inlet is provided on the upper front side of the water tank.
[0011] Preferably, the water inlet is connected to an external water pipe, and a slot is provided on the lower right side of the casing.
[0012] Preferably, the bottom of the water tank is connected to a water outlet pipe, which extends through a slot into the interior of the shell.
[0013] Preferably, the left end of the housing is connected to a handrail, and two triangular blocks are provided.
[0014] The beneficial effects of this utility model are: 1. By setting up a lifting component, the motor is started and stopped by a microcontroller. The motor drives the lead screw to rotate on the limit frame, which in turn causes the lead screw to slide the lifting block inside the housing. The movement of the lifting block causes the cutting machine to move on the housing, thus pressing the cutting machine down. The descent distance can be set according to the microcontroller settings to achieve precise adjustment. The housing can cover the cutting machine to prevent the waste chips from flying out and to prevent the saw blade from breaking and flying out, thus improving safety. In the current road repair cutting device, it is necessary to manually lift the device and slowly lower it to the ground during use, which is cumbersome and inefficient. In addition, the debris generated during cutting and the potentially broken circular saw blade are easy to fly out, posing a safety threat to the surrounding personnel. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Please see Figures 1-4 This utility model provides an embodiment of a road cutting device, including a housing 1 and a lifting assembly. The lifting assembly is located on the top of the housing 1 and inside the housing 1. The lifting assembly includes a top plate 21, a limiting frame 22, a motor 23, a lead screw 24, a lifting block 25, a cutting machine 26, and a microcontroller 27. The housing 1 is rectangular. The top of the housing 1 is connected to the top plate 21. The limiting frame 22 is connected to the lower inside of the housing 1. The motor 23 is connected to the top right side of the top plate 21. The output end of the motor 23 extends into the housing 1 and is connected to the lead screw 24. The lead screw 24 is connected to the limiting frame 22. The outer end of the lead screw 24 is threadedly connected to the lifting block 25. The lifting block 25 is slidably connected to the housing 1. The left end of the lifting block 25 is connected to the cutting machine 26. The front end of the housing 1 is connected to the microcontroller 27, which is electrically connected to the motor 23. 27 is electrically connected to the cutting machine 26, and the cutting machine 26 is slidably connected to the housing 1. By setting up a lifting component, the microcontroller 27 controls the start and stop of the motor 23. The motor 23 drives the lead screw 24 to rotate on the limit frame 22, thereby causing the lead screw 24 to drive the lifting block 25 to slide inside the housing 1. The movement of the lifting block 25 drives the cutting machine 26 to move on the housing 1, thereby causing the cutting machine 26 to press down. According to the settings of the microcontroller 27, the descent distance can be set to achieve precise adjustment. The housing 1 can cover the cutting machine 26 to prevent the waste chips cut by the cutting machine 26 from flying, and also to prevent the saw blade from breaking and flying out, thus improving safety. This solves the problem that existing road repair cutting devices require manual lifting and slow lowering to the ground during use, which is cumbersome and inefficient. In addition, the debris and potentially broken circular saw blades generated during cutting are easy to fly, posing a safety threat to the surrounding personnel.
[0019] Please see Figures 1-4In this embodiment, auxiliary blocks 31 are connected to the lower sides of the front and rear ends of the shell 1. There are two auxiliary blocks 31. The auxiliary blocks 31 are used to support the shell 1. A triangular block 32 is connected to the end of the auxiliary block 31 away from the shell 1. Two movable wheels 33 are symmetrically connected to the bottom of the auxiliary block 31 around its vertical center line. The movable wheels 33 can assist the shell 1 in moving. There are four movable wheels 33. A water tank 34 is connected to the right end of the shell 1. A water inlet 35 is provided on the upper front side of the water tank 34. The water inlet 35 can be connected to an external water pipe to fill the water tank 34 with water.
[0020] Please see Figures 2-4 In this embodiment, the water inlet 35 is connected to an external water pipe, and a slot 36 is provided on the lower right side of the housing 1. The slot 36 facilitates viewing the cutting depth of the circular saw. The bottom of the water tank 34 is connected to a water outlet pipe 37, which extends through the slot 36 into the interior of the housing 1. The water outlet pipe 37 sprays water onto the circular saw through the slot 36 to cool it down. A handrail 38 is connected to the left end of the housing 1. Two triangular blocks 32 are provided. The triangular blocks 32 are used for aiming to prevent the cutting position from deviating.
[0021] When working, grasp the handle 38 and push the device. The device moves via the moving wheels 33 on the auxiliary block 31 to the cutting area. The microcontroller 27 controls the motor 23 to start and stop. The motor 23 drives the lead screw 24 to rotate on the limit frame 22, which in turn causes the lead screw 24 to slide the lifting block 25 inside the housing 1. The movement of the lifting block 25 causes the cutting machine 26 to move on the housing 1, thus pressing down the cutting machine 26. The descent distance can be set according to the microcontroller 27 settings to achieve precise adjustment. Start the cutting machine 26 to cut the road surface. The housing 1 can cover the cutting machine 26 to prevent the waste chips from the cutting machine 26 from flying and to prevent the saw disc from breaking and flying out, thus improving safety. Connect the water inlet 35 to the external water pipe, and water enters the water tank 34. Then, water is sprayed onto the saw disc of the cutting machine 26 through the water outlet 37 to cool the saw disc on the cutting machine 26.
[0022] Through the above steps, by setting up the lifting component, the microcontroller 27 controls the start and stop of the motor 23. The motor 23 drives the lead screw 24 to rotate on the limit frame 22, thereby causing the lead screw 24 to drive the lifting block 25 to slide inside the housing 1. The movement of the lifting block 25 drives the cutting machine 26 to move on the housing 1, thereby causing the cutting machine 26 to press down. According to the settings of the microcontroller 27, the descent distance can be set to achieve precise adjustment. The housing 1 can cover the cutting machine 26 to prevent the waste chips cut by the cutting machine 26 from flying, and also to prevent the saw blade from breaking and flying out, thus improving safety. This solves the problem that existing road repair cutting devices require manual lifting and slow lowering to the ground during use, which is cumbersome and inefficient. In addition, the debris and potentially broken circular saw blades generated during cutting are easy to fly, posing a safety threat to the surrounding personnel.
