[0024] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0025] like Figure 1-7 As shown, this construction cutting device includes a vehicle body 1, which serves as the support and mounting base for the entire device, bearing all components. A rear wheel assembly 2 is located at the bottom rear of the vehicle body 1. The rear wheel assembly 2 provides primary support and rolling functionality during movement, ensuring the device can move smoothly on the ground.

[0026] A lifting frame 3 is provided in the middle of the vehicle body 1. The design of the lifting frame 3 allows the components related to the casters 9 to be adjusted up and down, thereby adapting to different working conditions and ground conditions. That is, when the lifting frame 3 rises, the vehicle body 1 falls; when the lifting frame 3 falls, the vehicle body 1 rises.

[0027] The bottom of the lifting frame 3 is equipped with omnidirectional wheels 9, which have the characteristic of omnidirectional rotation. This makes the movement of the device more flexible and convenient when it is not in operation, and can easily achieve operations such as turning. This solves the problem of inconvenient movement caused by the inability of the front and rear wheels to turn in the prior art.

[0028] The caster wheel 9 is provided with a insertion hole 95, and the lifting frame 3 is provided with a insertion rod 91. The insertion rod 91 is configured to engage with the insertion hole 95 in the working state. In the working state, inserting the insertion rod 91 into the insertion hole 95 can fix the position of the caster wheel 9, preventing it from rotating randomly during the cutting process and ensuring the stability and accuracy of the cutting. When moving in the non-working state, the insertion rod 91 can be pulled out, and the caster wheel 9 can rotate freely, facilitating the movement of the device.

[0029] A cutting blade 5 is mounted on the vehicle body 1 and rotates. The cutting blade 5 is the core working component of the device, which cuts the road surface used for construction by rotating. This design allows the device to flexibly switch between mobile and working states, ensuring both ease of movement and stability of the cutting operation.

[0030] In some further embodiments, the lifting frame 3 is provided with a support frame 90, the plug rod 91 slides through the support frame 90, the plug rod 91 is provided with a baffle 94, the baffle 94 is located in the support frame 90, the support frame 90 is provided with a first spring 93, the first spring 93 is sleeved on the plug rod 91, and the plug rod 91 is located outside the support frame 90 with an adjusting nut 92 screwed on it.

[0031] Rotating the adjusting nut 92 in one direction compresses the first spring 93, allowing the insertion rod 91 to rise, thus enabling the caster wheel 9 to rotate freely for easy movement when not in operation. When rotating the adjusting nut 92 in the opposite direction, the insertion rod 91 descends under the action of the first spring 93, allowing the insertion rod 91 to engage with the insertion hole 95, thereby locking the rotation of the caster wheel 9 and ensuring that the cutting device can move in a straight line when in operation.

[0032] In some further embodiments, the lifting frame 3 includes a support shaft 33, a rotating screw 32, a connecting plate 31, and two sliding columns 30. The sliding columns 30 slide vertically through the vehicle body 1, and their design allows the lifting frame 3 to slide up and down along the vehicle body 1, achieving the lifting function. The two ends of the connecting plate 31 are respectively connected to the tops of the two sliding columns 30, and the two ends of the support shaft 33 are respectively connected to the bottoms of the two sliding columns 30. The connecting plate 31 and the support shaft 33 work together to connect the two sliding columns 30 into a whole, ensuring the stability and rigidity of the lifting frame 3.

[0033] Rotating screw 32 rotates to connect connecting plate 31 and support shaft 33, and is threaded through to vehicle body 1. By rotating rotating screw 32, since rotating screw 32 is threaded to vehicle body 1, the rotational motion of rotating screw 32 will be converted into the vertical linear motion of lifting frame 3, thereby realizing the height adjustment of lifting frame 3 relative to vehicle body 1.

[0034] By setting up the lifting frame 3, the height of the lifting frame 3 can be precisely adjusted according to actual work needs, thereby adjusting the position of the casters 9 and the cutting depth of the cutting blade 5, improving the practicality and adaptability of the device.

[0035] In some further embodiments, the vehicle body 1 is equipped with a motor 4, which serves as a power source to provide power for the rotation of the cutting blade 5. The motor 4 drives the cutting blade 5 to rotate via belt drive, which has advantages such as simple structure, smooth transmission, and shock absorption.

[0036] During operation, after motor 4 starts, it travels through the belt and pulley.

[0037] Power is transmitted to the cutting blade 5, causing it to rotate at high speed, thereby cutting the road surface. This transmission method effectively reduces noise and vibration during transmission, improves the operational stability of the device, and the belt drive has a certain degree of elasticity, which can adapt to load changes that may occur during the cutting process, protecting the motor 4 and the cutting blade 5, and extending the service life of the device.

[0038] In some further embodiments, a support rod 6 is provided on the rear side of the vehicle body 1, which provides a mounting base for the adjustment handle 7.

[0039] An adjustment handle 7 is rotatably mounted on the top of the upright pole 6. The adjustment handle 7 facilitates the movement and operation of the device by the operator. The operator can push or pull the device by gripping the adjustment handle 7 to move it between different positions. Furthermore, the rotatable design of the adjustment handle 7 allows the operator to adjust its angle according to their own operating habits and actual needs, improving operational comfort and convenience.

[0040] In some further embodiments, the top of the upright 6 is provided with a sleeve 60, and a through hole 61 is provided radially through the sleeve 60, providing space for the installation of the rotating column 80.

[0041] The adjusting handle 7 has rotating columns 80 at both ends. The rotating columns 80 are rotatably mounted in the sleeve 60, so that the adjusting handle 7 can rotate relative to the upright 6.

[0042] The rotating column 80 has multiple adjusting holes 81 spaced circumferentially. These holes 81 are designed to engage with the locking rod 8 to lock the rotation of the adjusting handle 7. The locking rod 8 is elastically slidably mounted on the adjusting handle 7. When the locking rod 8 is inserted into the adjusting hole 81 through the through hole 61, the rotation of the adjusting handle 7 relative to the upright column 6 is locked. This design allows the operator to fix the adjusting handle 7 at a specific angle as needed, preventing it from rotating arbitrarily during operation and ensuring operational stability and safety. When adjusting the angle of the adjusting handle 7, simply pull the locking rod 8 to disengage it from the adjusting hole 81, then rotate the adjusting handle 7 to the appropriate angle, and finally insert the locking rod 8 into the corresponding adjusting hole 81. The operation is simple and convenient.

[0043] In some further embodiments, the adjusting handle 7 is provided with a sliding sleeve 70, through which the locking rod 8 slides. The sliding sleeve 70 provides guidance for the sliding of the locking rod 8, allowing it to slide in a specific direction and ensuring that the locking rod 8 can be accurately inserted into the adjusting hole 81. The adjusting handle 7 is provided with a guide rod 71, the end of which slides through the locking rod 8 away from the handle. The guide rod 71 further restricts the sliding direction of the locking rod 8, improving the stability of the sliding of the locking rod 8.

[0044] A second spring 72 is fitted onto the guide rod 71, located between the locking rod 8 and the adjusting handle 7. The function of the second spring 72 is to provide elastic force to the locking rod 8, ensuring that the locking rod 8 remains inserted into the adjusting hole 81 when no external force is applied, preventing the locking rod 8 from accidentally disengaging from the adjusting hole 81 and ensuring the reliability of the adjusting handle 7's locking. When it is necessary to unlock the adjusting handle 7, simply overcome the elastic force of the second spring 72 to pull the locking rod 8, causing it to disengage from the adjusting hole 81. This operation is convenient and ensures the stability of the locking mechanism.

[0045] In some further embodiments, the vehicle body 1 is provided with a slot, the design of which makes it possible to adjust the mounting position of the motor 4.

[0046] The length direction of the slot is consistent with the length direction of the line connecting motor 4 and cutting blade 5.

[0047] The base of motor 4 is connected to a slotted hole via bolts. By adjusting the position of the bolts in the slotted hole, the mounting position of motor 4 on the vehicle body 1 can be changed. Since motor 4 drives the cutting blade 5 to rotate via belt drive, adjusting the position of motor 4 can change the belt tension. Appropriate belt tension ensures the efficiency and stability of the belt drive, reduces belt slippage, and improves the working performance of the device. At the same time, this design also makes the installation and maintenance of motor 4 more convenient, allowing for flexible adjustment of the motor 4's position according to actual conditions, thus improving the maintainability and adjustability of the device.

[0048] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
