Embodiment 1

[0021] see Figure 1-4 , in an embodiment of the present invention, a road slitting device includes a car body 1, a cutting wheel 2 and a drive motor 11; a cutting wheel 2 is provided below the car body 1, and the cutting wheel 2 is connected to a protective car body through a wheel shaft 9 in rotation. The cover 3 and the axle 9 are connected with a driving motor 11 through the first transmission belt 10; the upper end of the protective cover 3 is fixedly connected with a lifting frame 4, and the driving motor 11 is fixedly connected with the lifting frame 4; the lifting frame 4 is a rectangular frame structure, The lifting frame 4 runs through the trolley 1 and extends to the top of the cart 1; the lifting frame 4 penetrates and is threadedly connected with a screw rod 5, the screw rod 5 is rotationally connected with the cart 1 through a bearing seat, and the upper end of the screw rod 5 is fixedly connected with an adjustable Wheel 6, rotate adjustment wheel 6, screw mandr...

Embodiment 2

[0024] The difference between this embodiment and Embodiment 1 is that: the front end of the cart 1 is rotatably connected with a fixed direction roller 24, and the direction of the fixed roller 24 is fixed; the rear end of the cart 1 is provided with an adjustable direction wheel 25, which can adjust the direction Wheel 25 is rotatably connected with lower limit disc 26, and lower limit disc 26 is connected with upper limit disc 27 through bearing rotation, and upper limit disc 27 is fixedly connected with cart 1, and lower limit disc 26 and upper limit disc 27 are provided with relative setting limits. Position hole 28, elastic latch 29 is plugged in the limit hole 28, and the cart 1 is provided with a limit hook 30. Specifically, when the slit is performed, the cart 1 needs to move linearly. At this time, the elastic latch 29 is inserted into the In the limit hole 28, when the operation is finished, the cart 1 needs to be moved, and the elastic latch 29 is pulled out from th...

Abstract

The invention discloses a joint cutting device for a road. The device comprises a car body, a cutting wheel and a drive motor. The cutting wheel is arranged below the car body. A protective cover is rotationally connected to the cutting wheel through an axle. A lifting frame is fixedly connected to the upper end of the protective cover. A lead screw penetrates through and is in threaded connectionwith the lifting frame, and an adjusting wheel is fixedly connected to the upper end of the lead screw. By arranging the lifting frame, the lead screw, the adjusting wheel, a pointer and a graduatedscale, the height of the cutting wheel can be efficiently adjusted, it is ensured that the cutting depth is consistent, and the joint cutting effect is improved; by arranging a piston disc of a pistoncylinder in linkage with the axle of the cutting wheel, water supply of a nozzle is achieved through a linkage structure; by arranging an adjustable steering wheel, an upper limiting disc, a lower limiting disc, an elastic plug pin and a limiting hook, movement is convenient during non-operation while linearity of the advancing trajectory of a trolley during cutting is ensured.

Description

technical field [0001] The invention relates to the field of slitting equipment, in particular to a slitting device for roads. Background technique [0002] Concrete pavement shrinkage joints refer to the horizontal false joints that do not penetrate the pavement slab set on the pavement to ensure that the cement concrete pavement will not produce irregular cracks due to shrinkage during the hardening process and when the temperature is lowered. The seam width is not greater than 1cm, and the seam depth is 1 / 3 of the board thickness. The shrinkage joint spacing of plain concrete pavement is usually 4-7m, and they are generally arranged at equal distances, but they can also be arranged at unequal intervals. Most of the shrinkage joints are perpendicular to the driving direction, but they can also be arranged obliquely. The pressure joint method is used for construction before the initial setting of the concrete, but most of the joints are sawed with a sawing machine. Its f...
