DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figures 1-8In one embodiment of the present invention, a road maintenance device has a relative first direction x, a second direction y, and a third direction z. The road maintenance device includes a direction-changing frame module and a spray module. The direction-changing frame module is rotatably mounted on the front end of the road maintenance vehicle, and the rotation direction of the direction-changing frame module matches the curvature of the road. The direction-changing frame module is provided with a retractable spray module. The retractable state of the spray module is associated with the rotation direction of the direction-changing frame module, and the spray pressure of the spray module is related to the retractable amount. Related; the injection module includes an injection assembly 2, and the injection assembly 2 includes a main cylinder 201, an inner sliding cylinder 207 and an outer sliding cylinder 209. The main cylinder 201 is fixedly assembled on the front end of the maintenance vehicle, and several sections of inner sliding cylinder 207 and outer sliding cylinder 209 are provided at both ends of the main cylinder 201. The inner sliding cylinder 207 and the outer sliding cylinder 209 are arranged at intervals, and the inner sliding cylinder 207 and the outer sliding cylinder 209 are limitedly slidably assembled, and the inner sliding cylinder 207 close to the side of the main cylinder 201 is limitedly slidably inserted in the main cylinder 201.

[0025] In actual application of this embodiment, the road maintenance device consists of a changing frame module and a spray module. The changing frame module is rotatably installed on the front side of the road maintenance vehicle, and the rotation direction of the changing frame module is related to the curvature direction of the current road side. When the curing agent is sprayed through the spray module, the changing frame module enables the spray module to adaptively adjust its spray direction according to the curvature of the road, and during the adjustment process, the telescopic amount of the spray module changes synchronously. According to the telescopic change of the telescopic module, the number of spray holes can be further adjusted, so that when the pressure of the pump is constant, the spray pressure at the end of the spray hole can be adaptively adjusted, thereby making the curing agent evenly sprayed at the curved position of the road surface, thereby improving the utilization rate of the curing agent.

[0026] See also Figure 1 and Figure 2 In a preferred embodiment of the present invention, the direction-changing frame module includes a frame assembly 1, which includes a main frame 101, a plate frame 102, a side bracket 103, a positioning frame 104, a guide rail 105, a telescopic cylinder 106 and a traction arm 107. One end of the main frame 101 is fixedly assembled on the front end of the road maintenance vehicle, and the other end of the main frame 101 is fixedly assembled with the plate frame 102.

The end of the movable shaft of the telescopic cylinder 106 is rotatably assembled with two sets of traction arms 107, and the end of the traction arm 107 is rotatably assembled on one side of the positioning frame 104.

[0027] During actual application of this embodiment, the main frame 101 is fixedly mounted on the front end of a road maintenance vehicle, and during the driving of the maintenance vehicle, the movable shaft thereon is driven to extend and retract by the telescopic cylinder 106 arranged at the bottom of the plate frame 102. During the movement, the movable shaft on one side of the telescopic cylinder 106 synchronously pulls the traction arm 107 to move in the xoy plane. Since the end of the traction arm 107 is rotatably mounted on the positioning frame 104, the movable shaft of the telescopic cylinder 106 synchronously pulls the positioning frame 104 to slide on the side bracket 103 during the movement, thereby controlling the two groups of positioning frames 104 to extend and retract in opposite directions in the second direction y, thereby adjusting the distance between the two groups of positioning frames 104, so that the injection module movably arranged between the two groups of positioning frames 104 can synchronously adjust its injection area according to the road width.

[0028] See also Figure 3 and Figure 6 In a preferred embodiment of the present invention, the injection assembly 2 further includes a guide tube 202, a driven wheel 203, a rotary sealing ring 204 and a drainage tube 205. The guide tube 202 is fixedly arranged on the main cylinder 201 and is connected to the main cylinder 201. The driven wheel 203 is fixedly assembled on the outside of the guide tube 202. One end of the rotary sealing ring 204 is rotatably sleeved on the guide tube 202. The other end of the rotary sealing ring 204 is connected to the drainage tube 205. The drainage tube 205 is used to transport the curing agent into the main cylinder 201.

[0029] In actual application of this embodiment, the guide tube 202 is fixedly assembled on the main cylinder 201, and a driven wheel 203 is fixedly provided on the outer diameter end of the guide tube 202. The rotating sealing ring 204 is rotatably assembled on the guide tube 202 through a rotating sealing structure, and the curing agent is pumped into the main cylinder 201 through the drainage tube 205 at one end thereof, so that when the main cylinder 201 rotates in the xoy plane, the drainage tube 205 always maintains a connected state with the main cylinder 201.

[0030] Furthermore, the injection assembly 2 further includes a first injection hole 206, a second injection hole 208, a third injection hole 210 and a side bracket 211, wherein the first injection hole 206 is arranged on the outer surface of the main cylinder 201, the second injection hole 208 is arranged on the outer surface of the inner slide cylinder 207, and the third injection hole 210 is arranged on the outer surface of the outer slide cylinder 209.

Similarly, when the inner sliding cylinder 207 slides and shrinks into the outer sliding cylinder 209, the third injection hole 210 at one end of the outer sliding cylinder 209 is blocked by the shell of the inner sliding cylinder 207. At the same time, the second injection hole 208 on the inner sliding cylinder 207 is blocked by the shell of the outer sliding cylinder 209, thereby reducing the number of the first injection holes 206 and the second injection holes 208 on the outer sliding cylinder 209 and the inner sliding cylinder 207. The number of the third injection hole 210 and the second injection hole 208 for injecting the curing agent is reduced so that the number of effective injection holes of the several inner sliding cylinders 207 and the outer sliding cylinders 209 can be changed synchronously during the sliding and retracting process. When the pumping pressure on one side of the drainage tube 205 is constant, the pressure on the several orifice sides is synchronously adjusted, thereby adjusting the injection pressure on the injection hole side in real time. A side connecting frame 211 is fixedly connected to one side of the outer sliding cylinder 209 at the end side, and a slider 212 is rotatably connected to the end of the side connecting frame 211.
