Description

Technical Field

[0001] The utility model relates to the technical field of subgrade compaction, in particular to an intelligent subgrade compaction device for road engineering. Background Technique

[0002] The subgrade is the foundation of the track or road surface, and is a geotechnical structure formed by excavation or filling. The main function of the subgrade is to provide necessary conditions for the laying of the track or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and rolling stock or the road surface and traffic load, and at the same time transfer and disperse the load deep into the foundation. In the longitudinal section, the subgrade must ensure the elevation required by the line. In the plane, the subgrade is connected with bridges and tunnels to form a complete and continuous line. The road subgrade needs to be compacted during construction.

[0003] When performing subgrade compaction operations, the subgrade usually contains stones. Since the stones and soil cannot be integrated, if the stones are not removed, it will affect the flatness of the subgrade. At the same time, it will also cause certain damage to the roller. Content of the Utility Model

Specific implementation manners

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1-5 , an intelligent road engineering subgrade compaction device provided by the embodiment of the present utility model, includes: a frame 1; a road roller 2, which is rotatably connected to the frame 1.

[0026] In the embodiment of the present utility model: a rejection mechanism 3, the rejection mechanism 3 is used to reject stones in the advancing direction of the road roller 2 and push the stones to both sides of the road roller 2; specifically, it includes a reciprocating lead screw 31 rotatably connected to the frame 1, and a reciprocating plate 32 is slidably connected to the frame 1; more specifically, a chute is opened on the frame 1, a slide bar is fixedly connected to the reciprocating plate 32, and the slide bar is slidably connected in the chute; a rack 33 is fixedly connected to the reciprocating plate 32, and there are two rejection components on the frame 1, and each rejection component includes a first rotating shaft 34 rotatably connected to the frame 1, a gear 35 is fixedly connected to the first rotating shaft 34, the gear 35 is engaged with the rack 33, a ratchet wheel 36 is fixedly connected to the first rotating shaft 34, and the rejection component further includes a ratchet pawl 37 rotatably connected to the frame 1, specifically, an elastic member is arranged between the ratchet pawl 37 and the frame 1, and the elastic member is a torsion spring; the ratchet pawl 37 is engaged with the ratchet wheel 36, a second rotating shaft 38 is rotatably connected to the ratchet pawl 37, and two cross plates 39 are fixedly connected to the second rotating shaft 38, and a plurality of rejection rods 310 are fixedly connected to both cross plates 39.

[0027] It is worth mentioning that: the directions of the ratchet pawls 37 in the two rejection components are arranged in the opposite direction.

[0028] During use, the reciprocating lead screw 31 drives the reciprocating plate 32 and the rack 33 to move in a reciprocating straight line. During the movement of the rack 33, it meshes with the two gears 35 in sequence. Since the directions of the two pawls 37 are arranged in the opposite direction, when one ratchet wheel 36 drives its corresponding pawl 37 to rotate, the other ratchet wheel 36 cannot drive its corresponding other pawl 37 to rotate, that is, it cannot drive the second rotating shaft 38 and the removing rod 310 to rotate. Generally speaking, the two removing components work alternately and intermittently.

[0029] As a preferred embodiment: It further includes a transmission mechanism 4. The transmission mechanism 4 is used to transmit the power of the rotation of the road roller 2 to the reciprocating lead screw 31. It includes a first belt pulley 41 fixedly connected to the road roller 2, a second belt pulley 42 fixedly connected to the reciprocating lead screw 31, and a belt 43 is arranged between the first belt pulley 41 and the second belt pulley 42.

[0030] As a preferred embodiment: A scraper 5 is fixedly connected to the frame 1, and the scraper 5 abuts against the road roller 2. The scraper 5 is used to scrape off the soil attached to the road roller 2.

[0031] As a preferred embodiment: It further includes two knocking mechanisms 6. The two knocking mechanisms 6 correspond to the two removing components respectively. The knocking mechanism 6 is used to knock the scraper 5. The purpose is that after the scraper 5 cleans the soil on the road roller 2, the scraper 5 will also be attached with soil, and the knocking mechanism 6 can knock the scraper 5, so that the soil on the scraper 5 will fall with the vibration generated by the knocking. It includes a connecting rod 61 fixedly connected to the first rotating shaft 34. A wave groove 62 is opened on the connecting rod 61. A vertical plate 64 is fixedly connected to the scraper 5. A knocking rod 63 is vertically slidably connected to the vertical plate 64. Specifically, a vertical groove is opened on the vertical plate 64, and the knocking rod 63 is slidably connected in the vertical groove. One end of the knocking rod 63 is rotationally abutted against the wave groove 62, and the other end is abutted against the scraper 5. Specifically, the abutting manner of the knocking rod 63 against the wave groove 62 is that a abutting rod is fixedly connected to the knocking rod 63, and the abutting rod is rotationally abutted against the wave groove 62.

[0032] When the connecting rod 61 rotates, since the knocking rod 63 is vertically slidably connected to the vertical plate 64, it will drive the knocking rod 63 to do vertical reciprocating linear motion through the rotational abutment between the wave groove 62 and the knocking rod 63, so as to knock the scraper 5, so that the soil on the scraper 5 will fall with the vibration generated by the knocking.

[0033] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
