Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, in particular to a highway water-stable base trimming device. Background Art

[0002] In highway construction, cement stabilized crushed stone is a new type of semi-rigid pavement structure used in the construction of subbase and base of high-grade highways in recent years. As the underlying layer of asphalt concrete, it has the advantages of good plate properties, water stability and frost resistance, mechanical strength that can be adjusted as needed, and strong overall bearing capacity.

[0003] In order to ensure the quality of the base paving, ultra-wide paving is generally carried out. After the water-stabilized base is accepted, the ultra-wide part of the water-stabilized base finished material is cut off to ensure that the density, elevation and flatness of the edge of the water-stabilized base meet the quality requirements. The regular cutting edge is also convenient for the subsequent installation of the curbstone. If you want to trim it, it is inevitable to use a highway water-stabilized base trimming device.

[0004] Although the trimming device in the prior art is convenient for regular trimming of the extra-wide part of the finished water-stable base material, it is inevitable that there are still some shortcomings in its actual use. For example, the device lacks a pushing mechanism, which causes the cut pieces to stick to both sides of the road, resulting in the need to pre-clean the pieces when the curb is installed later. In order to avoid such problems, a highway water-stable base trimming device is proposed to solve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a highway water-stable base trimming device, which solves the problem that the device lacks a pushing mechanism, resulting in the cut debris sticking to both sides of the road, causing the subsequent construction on the side of the road to be affected by the obstruction of the debris.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a highway water-stable base cutting device, comprising a trolley and a counterweight block, the counterweight block is fixedly arranged on the top of the trolley, the top of the trolley is fixedly connected with a mounting frame, the inside of the mounting frame is slidably connected with a bearing plate, the top of the mounting frame is fixedly connected with an electric telescopic rod through a bracket, and the bottom of the extended end of the electric telescopic rod is fixedly connected to the top of the bearing plate, the top of the bearing plate is fixedly connected with a driving motor, and the output shaft of the driving motor is fixedly connected with a rotating shaft through a coupling, the surface of the rotating shaft is fixedly connected with a cutting disk, the rear side of the bearing plate is fixedly connected with a sliding frame, the top of the sliding frame is provided with a mounting block, and a push plate is slidably arranged on one side of the mounting block, one side of the push plate is fixedly connected with an inclined block, the surface of the rotating shaft is fixedly connected with a cam, and the top of the mounting frame is slidably connected with a push rod used in conjunction with the cam and the inclined block.

[0007] Preferably, one side of the mounting block is fixedly connected to a limiting sleeve via a groove, the limiting sleeve is internally slidably connected to a limiting rod, and a first return spring is fixedly connected between the limiting rod and the limiting sleeve, and one end of the limiting rod is fixedly connected to the side of the push plate.

[0008] Preferably, the top of the supporting plate is fixedly connected to a slide plate via a bracket, the inside of the slide plate is slidably connected to a sliding plate, and one end of the sliding plate is fixedly connected to the side of the push rod, and a second return spring is fixedly connected between the sliding plate and the slide plate.

[0021] Further: in order to facilitate cutting and push the cut pieces away from the road side, a slide frame 9 is fixedly connected to the rear side of the carrier plate 5, a mounting block 10 is arranged on the top of the slide frame 9, and a push plate 11 is slidably arranged on one side of the mounting block 10, a slanted block 12 is fixedly connected to one side of the push plate 11, a cam 13 is fixedly connected to the surface of the rotating shaft 7, and a push rod 14 used in conjunction with the cam 13 and the slanted block 12 is slidably connected to the top of the mounting frame 3. As a detailed explanation: a drag reduction roller used in conjunction with the cam 13 is rotatably arranged inside the push rod 14 through a slot;

[0022] As a detailed explanation: one side of the mounting block 10 is fixedly connected to the limiting sleeve 15 through a groove, the limiting sleeve 15 is internally slidably connected to the limiting rod 16, and a first return spring 17 is fixedly connected between the limiting rod 16 and the limiting sleeve 15, one end of the limiting rod 16 is fixedly connected to the side of the push plate 11, one side of the push plate 11 is fixedly connected to a guide slide bar 23, and one end of the guide slide bar 23 passes through and extends to one side of the mounting block 10, one side of the mounting block 10 is provided with a guide through groove 24 slidably adapted to the guide slide bar 23, the top of the carrying plate 5 is fixedly connected to the slide plate 18 through a bracket, the slide plate 18 is internally slidably connected to the sliding plate 19, and one end of the sliding plate 19 is fixedly connected to the side of the push rod 14, and a second return spring 20 is fixedly connected between the sliding plate 19 and the slide plate 18.

[0023] Furthermore: to facilitate the adjustment of the pushing range of the push plate 11, a threaded rod 21 is rotatably provided on the inner wall of the slide frame 9 through a bearing, and one end of the threaded rod 21 extends to the outside of the slide frame 9, and a threaded sleeve 22 is connected to the surface of the threaded rod 21 and the internal thread of the slide frame 9, and the top of the threaded sleeve 22 is fixedly connected to the bottom of the mounting block 10.
