DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figures 1 to 5 As shown:
[0021] Embodiment 1: The utility model provides a cement stabilized gravel base leveling device, comprising: a leveling mechanism 1, comprising a connecting frame assembly 11, a leveling plate assembly 12 connected to the connecting frame assembly 11 for limited rotation, and an arc spring 13 arranged between the connecting frame assembly 11 and the leveling plate assembly 12; a mounting mechanism 2, comprising a mounting frame assembly 21 connected to the connecting frame assembly 11 for rotation, and a hydraulic cylinder 22 used to drive the connecting frame assembly 11 to rotate; one end of the hydraulic cylinder 22 is connected to the mounting frame assembly 21 for rotation, and the other end of the hydraulic cylinder 22 is connected to the connecting frame assembly 11 for rotation;
[0022] Among them, the mounting frame assembly 21 is fixed to the tail of the traction equipment by bolts. When the traction equipment moves, it will drive the entire device to move. By controlling the operation of the hydraulic cylinder 22, the leveling plate assembly 12 can be rotated around the connecting frame assembly 11, so that the leveling plate assembly 12 can be attached to the ground. When the leveling plate assembly 12 is dragged on the ground, the arc spring 13 will be compressed on the connecting frame assembly 11, thereby smoothing the gravel and cement on the ground. The arc spring 13 can make the leveling plate assembly 12 play a buffering role when it encounters hard objects. When the construction is completed, the hydraulic cylinder 22 can be controlled to work to lift the leveling plate assembly 12, thereby preventing the leveling plate assembly 12 from contacting the ground when the traction equipment moves.
[0023] Specifically, the connecting frame assembly 11 includes an axle hole frame 111 , a limiting bracket 112 is fixedly connected to the middle position of one side of the axle hole frame 111 , and a group of limiting stop edges 113 are also fixedly connected to the outer side of the axle hole frame 111 .
[0024] Specifically, the leveling plate assembly 12 includes a wing plate 121 , a shaft rod 122 is fixedly connected to one side of the wing plate 121 , an arc-shaped guide rod 123 is fixedly connected to the upper side of the wing plate 121 , and a baffle 124 is also fixedly connected to the edge of the wing plate 121 .
[0025] Specifically, the shaft rod 122 is rotatably embedded in the shaft hole frame 111, the limit bracket 112 is slidably embedded in the arc guide rod 123, the arc spring 13 is sleeved on the outside of the arc guide rod 123, the arc spring 13 drives the wing plate 121 away from the limit bracket 112, and a group of limit stops 113 can limit the shaft rod 122.
[0026] As can be seen from the above, when the wing plate 121 is dragged on the ground, the curved surface at the bottom of the wing plate 121 will contact the ground, so that the gravel and cement on the ground are smoothed. When the wing plate 121 hits a hard object, it will drive the arc spring 13 to be compressed on the limit bracket 112 to play a buffering role. A set of limit stops 113 can limit the rotation range of the shaft rod 122, so that the wing plate 121 can better fit the ground. The baffle 124 can intercept the gravel and cement to prevent the gravel and cement from moving to the upper side of the wing plate 121.
[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that an axis hole frame 114 is fixedly connected to the side of the axis hole frame 111 away from the limiting bracket 112, and a connecting shaft 115 is fixedly connected to the upper side of the axis hole frame 111; the mounting frame assembly 21 includes a mounting frame body 211, an axis rod 212 is fixedly connected to the outer side of the mounting frame body 211, and a connecting shaft 213 is fixedly connected to the upper edge of the mounting frame body 211.
[0028] Specifically, the second shaft rod 212 is rotatably embedded in the second shaft hole frame 114, one end of the hydraulic cylinder 22 is rotatably connected to the second connecting shaft 213, and the other end of the hydraulic cylinder 22 is rotatably connected to the first connecting shaft 115.
[0029] As can be seen from the above, the mounting frame body 211 is fixedly mounted on the traction equipment by bolts, and the operation of the hydraulic cylinder 22 can be controlled to make the shaft hole frame 111 rotate around the shaft rod 212 through the shaft hole frame 2 114, so that the wing plate 121 is placed on the ground.
