[0002] Road rollers are important equipment for road paving. They can compact the road surface to make it more compact. However, the requirements for road compactness vary depending on the application scenario.

[0003] A patent with application number CN202223542546.9 discloses a compaction mechanism of a double steel wheel roller, including a pressure wheel, a ring plate, a placement hole and a mounting frame. Ring plates are respectively provided at the left and right ends of the pressure wheel. Two sets of mounting frames are respectively installed on the left and right ends of the pressure wheel on the inner sides of the two sets of ring plates. Multiple sets of placement holes are circumferentially provided on the pressure wheel, and a weight adjustment mechanism is also included. The weight adjustment mechanism can be detachably installed in the placement hole.

[0004] In this structure, there is smooth contact between the outer side of the weight rod and the placement hole. When inserting, it is not convenient to align the mounting holes of the connecting plates at both ends of the weight rod with the mounting holes on the side of the pressure wheel, which increases the difficulty of installation. In addition, the installation and fixing method is to install and fix through No. 1 screw rod, No. 1 nut, No. 2 screw rod, and No. 2 nut, which is more complicated to operate. Utility Model Content

[0008] As a further solution of the utility model: four limit grooves are opened on the inner side of the installation groove, and limit protrusions are fixed on the outer side of the counterweight column at the four limit grooves, which can limit the rotation of the counterweight column and fix its position.

[0009] As a further solution of the utility model: a fastening plate is fixedly connected to one side of the steel wheel body between one end of two adjacent mounting plates, which can assist in fixing the position of the mounting plates.

[0020] 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.

[0021] Combined with Figure 1-4 The compacting mechanism of the double steel wheel roller of this embodiment includes: a steel wheel body 1 and a detachable counterweight structure. A plurality of mounting grooves 1.1 are opened on the side of the steel wheel body 1. The detachable counterweight structure includes a counterweight column 2 inserted in the mounting groove 1.1. Two connecting plates 2.1 are fixed on both sides of the counterweight column 2. Mounting plates 1.2 are fixed on both sides of the steel wheel body 1 next to the mounting groove 1.1 for installing the counterweight column 2.

[0022] The sides of the connecting plate 2.1 and the mounting plate 1.2 are both provided with threaded holes, in which bolts 3 are screwed and connected. One side of the mounting plate 1.2 is screwed and connected with a fastening nut 4 on the outer side of the bolt 3, and the position of the counterweight column 2 is fixed by the threaded fastening connection.

[0023] Four limiting grooves are provided inside the installation groove 1.1, and limiting protrusions 2.2 are fixed at the four limiting grooves outside the counterweight column 2, which can limit the rotation of the counterweight column 2 and fix its position.

[0024] A fastening plate 1.3 is fixedly connected between one end of two adjacent mounting plates 1.2 on one side of the steel wheel body 1, and can assist in fixing the position of the mounting plates 1.2.

[0025] A threaded deep hole 2.3 is provided on one side of the counterweight column 2, in which a disassembly bolt 5 is screwed and connected, and a connecting ring 5.1 is fixed at one end of the disassembly bolt 5. The connecting ring 5.1 can be hooked by an external lifting device to pull the counterweight column 2 out of the installation slot 1.1.

[0026] Connecting columns 1.4 are fixed on both sides of the steel wheel body 1, and a mounting flange 1.5 is fixed on one side of the connecting column 1.4, so that the steel wheel body 1 can be installed and fixed to an external roller.

[0027] The working principle of the compaction mechanism of the double steel wheel roller is:

[0028] When installing the counterweight column 2, first align the counterweight column 2 with the installation slot 1.1, and align the limiting protrusion 2.2 with the limiting slot, so that the connecting plate 2.1 can be parallel to the installation plate 1.2, and then insert the counterweight column into the installation slot 1.1, and then insert the bolt 3 into the threaded hole, and fix the position by tightening the nut 4, so that the counterweight column 2 is installed. When disassembling, only the bolt 3 needs to be removed, and then the disassembly bolt 5 is tightened and connected into the threaded deep hole 2.3, and it can be pulled out by an external crane to complete the disassembly, which is simple and quick.

[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
