Description

Technical Field

[0001] The utility model relates to the technical field of road construction, and more specifically, to a corner compaction structure. Background Art

[0002] An excavator-type vibrating plate compactor consists of three parts: a vibrating plate, a power unit, and a connecting device. The vibrating plate is the part that contacts the ground and performs compaction. The power unit is the internal vibration motor that transmits hydraulic vibrations to the vibrating plate for compaction. The vibrating plate compactor is typically connected to other machinery to achieve the compaction function.

[0003] The corner compaction structure of this application is mainly designed for the vibration plate and connection part of the excavator-type vibration plate compactor. The existing design of the vibration plate and connection part has the following problems in actual use:

[0004] 1. After the bolt connection is adopted, since the bolt is designed to be circular, the connection part needs to be squeezed and fixed during installation. The circular structure design is prone to loosening during use, causing the whole to swing easily;

[0005] 2. The vibration plate is not easy to replace. When compacting corners of different shapes, the vibration plate structure of different shapes cannot be quickly replaced. The effect of using a single-shaped vibration plate to treat the compacted corners is not ideal;

[0006] 3. The connection position with the end hand of the excavator arm, that is, the pin installation position, needs to maintain the size structure of the end hand of the excavator arm for easy fixation. When the top size of the connecting part does not match the size of the end hand of the excavator arm, it is inconvenient to pad multiple gaskets to maintain extrusion stability. Utility Model Content

[0007] In order to overcome the above-mentioned defects of the prior art, the utility model provides a compaction structure for corners.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a compaction structure for corners, including a connecting body connected to the end hand of an excavator arm, a positioning pin connected between the connecting body and the end hand of the excavator arm, the end of the positioning pin is located on the outside of the end hand of the excavator arm and is connected to a first nut, the bottom of the connecting body is connected to a cylindrical tube, the bottom end of the cylindrical tube is fixedly connected to a steel plate, the top of the connecting body is located on the inner side of the end hand of the excavator arm and is movably connected to a movable block, the positioning pin is passed through the inner side of the movable block, a screw is inserted horizontally between the top of the connecting body and the bottom of the movable block, and the outside of the screw is located at the inner and outer sides of the movable block and is respectively connected to a third nut and a second nut.

[0011] As a further improvement of the technical solution of the present invention, the top outer surface of the cylindrical tube is provided with an external thread, and the bottom of the connecting body is provided with an internal thread groove corresponding to the top connection of the cylindrical tube. The cylindrical tube and the bottom of the connecting body are connected by threads, and the top of the steel plate is welded and fixed to the bottom of the cylindrical tube.

[0012] As a further improvement of the technical solution of the present invention, a limiting block is provided at the bottom of the movable block, and a limiting sliding groove is provided on the outside of the top of the connecting body corresponding to the limiting block in the horizontal direction.

[0013] As a further improvement to the technical solution of the present invention, through holes are provided in the horizontal direction at the places where the screws are inserted, corresponding to the insides of the connecting body and the movable block.

By changing the existing circular hole structure into a square through-hole structure and replacing the existing latch structure with the positioning latch structure designed in this application, a square rod matching the square through-hole is provided on the positioning latch, and a stud is provided at the end of the square rod. After the square rod on the positioning latch is inserted into the square through-hole, it can maintain a more stable state and will not cause the problem of swinging due to looseness.
