Description

Technical Field

[0001] The utility model relates to the technical field of road rollers, in particular to a filled front beam for road rollers. Background Art

[0002] Usually, there are three main forms of weight distribution of vibratory rollers, namely, heavy front and light rear, equal weight, and light front and heavy rear. By adopting front and rear beams of different weights, the weight of the front and rear body of the roller can be reasonably distributed.

[0003] In order to be able to better adjust the weight of the front beam, a filled front beam is used. The weight of the front beam is changed by replacing the filler in the front beam. However, since the cover plate on the front beam and the positioning column in the front beam are fixed by multiple nuts, it is necessary to remove multiple nuts at a time to open the cover plate each time it is replaced, which is more troublesome. In addition, the front beam and the side plate are fixed by bolts, so the corresponding threaded holes need to be aligned before the bolts can be installed, resulting in the need to position the front beam while turning the bolts during installation, which is more troublesome. Therefore, it is necessary to design a filled front beam for a road roller to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a filled front beam for a road roller is proposed. The front beam fixes the cover plate and the front beam body by turning two knobs so that a plurality of limit rods are inserted into the limit holes, which is convenient for replacing the counterweight block. The rectangular groove and the T-block are arranged so that the front beam body can be quickly positioned, which is convenient for installation between the front beam body and the side plate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A filled front beam for a road roller comprises two side plates of the road roller, a front beam body is arranged in front of the two side plates of the road roller, a placement groove is arranged at the upper end of the front beam body, a plurality of positioning columns are fixedly connected to the inner bottom of the placement groove, and the plurality of positioning columns are provided with limiting holes, a cover plate is arranged at the upper end of the front beam body, a circular opening matching with the positioning columns is arranged on the cover plate, two rectangular plates are fixedly connected to the upper end of the cover plate, a screw rod is passed through and rotatably connected to the two rectangular plates, a movable plate is rotatably connected to the two screw rods, a plurality of limiting rods are fixedly connected to the adjacent sides of the two movable plates, and knobs are fixedly connected to the opposite sides of the two screw rods.

[0007] Preferably, the two movable plates are slidably connected to adjacent sides of the cover plate.

[0008] Preferably, the upper end of the cover plate is fixedly connected to two fixing plates, the two fixing plates are each provided with two first threaded holes, the two roller side plates are each provided with a second threaded hole, and bolts are threadedly connected together in multiple first threaded holes and corresponding second threaded holes.

[0010] Preferably, a counterweight block is placed in the placement groove, and the plurality of positioning columns all penetrate the counterweight block and are slidably connected to the counterweight block.

[0011] Preferably, the cover plate and the two fixing plates are integrally formed.

[0012] Compared with the existing technology, the advantages of this device are:

[0013] 1. Compared with the prior art, by setting the limiting rod and the limiting hole, when replacing the counterweight, it is only necessary to turn the knob to disengage the limiting rod and the limiting hole to replace the counterweight, which is convenient and quick;

[0014] 2. Compared with the prior art, by setting the T-block and the rectangular groove, during the installation process, it is only necessary to insert the upper end of the T-block into the rectangular groove and then move the front beam body downward to perform preliminary limiting, so that the threaded holes on the roller side plate and the fixed plate can be quickly aligned, which is convenient for the installation of the front beam body.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 A filled front beam for a road roller comprises two side plates 1 of the road roller, a front beam body 3 is arranged in front of the two side plates 1 of the road roller, a placement groove is arranged at the upper end of the front beam body 3, a plurality of positioning columns 13 are fixedly connected to the inner bottom of the placement groove, a counterweight block 14 is placed in the placement groove, a plurality of positioning columns 13 all penetrate the counterweight block 14 and are slidably connected to the counterweight block 14, a plurality of positioning columns 13 are all provided with limiting holes 15, a cover plate 4 is arranged at the upper end of the front beam body 3, a circular opening matching with the positioning columns 13 is arranged on the cover plate 4, two rectangular plates 6 are fixedly connected to the upper end of the cover plate 4, a screw rod 10 is penetrated and rotatably connected to the two rectangular plates 6, the screw rod 10 is a threaded rod, and a movable plate 7 is rotatably connected to the two screw rods 10, a plurality of limiting rods 9 are fixedly connected to the adjacent sides of the two movable plates 7, a knob 8 is fixedly connected to the opposite sides of the two screw rods 10, and the two movable plates 7 are slidably connected to the adjacent sides of the cover plate 4.

[0021] Among them, the upper end of the cover plate 4 is fixedly connected to two fixing plates 5, the cover plate 4 and the two fixing plates 5 are integrally processed, two first threaded holes are provided on the two fixing plates 5, and second threaded holes are provided on the two roller side plates 1. Bolts 2 are threadedly connected together in multiple first threaded holes and corresponding second threaded holes.

[0022] Wherein, adjacent sides of the two roller side plates 1 are fixedly connected with T-blocks 11 , and rectangular grooves 12 are provided on the left and right sides of the front beam body 3 .

[0023] The functional principle of the utility model can be explained through the following operation mode: first, the counterweight block 14 is placed in the placement groove, and then the cover plate 4 is placed on the front beam body 3, so that the multiple positioning columns 13 pass through the corresponding round openings, and then the two knobs 8 can be turned to rotate the screw rod 10, thereby causing the two movable plates 7 to move relative to each other, so that the multiple limiting rods 9 are inserted into the limiting holes 15, and the cover plate 4 is fixed to the front beam body 3;

[0024] Then, the front beam body 3 is lowered from between the two roller side plates 1, so that the upper end of the T-block 11 enters the rectangular groove 12, so that the front beam body 3 can be accurately positioned when it moves downward, so that the first threaded hole and the second threaded hole are aligned, and then the plurality of bolts 2 can be rotated to fix the roller side plate 1 and the two fixing plates 5;

[0025] When the counterweight 14 needs to be replaced, the multiple bolts 2 can be removed, and then the two knobs 8 can be rotated in the opposite direction to make the multiple limit rods 9 move away from the limit holes 15.
