Description

Technical Field

[0001] The present invention relates to the technical field of road paving, and specifically relates to a road subgrade tamping device and a tamping method. Background Technique

[0002] A road subgrade tamping device is a piece of equipment used in road construction, mainly used for tamping and leveling the subgrade. Its main function is to ensure the stability and durability of the subgrade by compacting soil and stones.

[0003] ‌Road subgrade tamping‌ refers to the treatment of the road subgrade through compaction technology to improve the bearing capacity and stability of the subgrade. In order to tamp the subgrade more evenly and quickly, especially when tamping a subgrade with a poor soil surface, multiple tamping treatments are required during the tamping construction. The existing road subgrade tamping devices usually have relatively low tamping efficiency, which is likely to lead to a prolonged construction period, and the low tamping efficiency is also likely to result in a deteriorated tamping effect. For this reason, we propose a road subgrade tamping device and a tamping method.

[0015] A ramming method for a roadbed ramming device includes the following steps: S1: First, install the equipment body on a special vehicle driven through a mounting frame to perform ramming operations. After a series of inspections, lower the body onto the area to be rammed to start the ramming operation; S2: Then start the hydraulic component on the body. The hydraulic component drives the main rammer to reciprocate up and down to hammer the rammer base. The main rammer hammers the rammer base multiple times. Through the impact of the main rammer and the self-weight of the body, the effect of ramming the roadbed soil surface is achieved; S3: During the ramming operation, to enhance the ramming effect and improve the operation efficiency at the same time, the force of the up and down movement of the main rammer can be utilized to cooperate with the toothed plate and the wide gear meshing with it.

When the pressing plate moves, it drives the stroke plate to reciprocate. While moving, it drives the screw rod to reciprocate up and down. The screw rod will be linked and cooperated with the mating block and mating slot holes in the rod seat tube, and can drive the rod seat tube to drive the cleaning rake to rotate through the bearing sleeve on the base plate, thereby realizing debris cleaning and being able to break up mud blocks, which can avoid debris affecting the ramming effect of the roadbed soil surface.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting the cooperation of the pre-tamping unit and the cleaning unit, the present invention can achieve the purpose of pre-tamping and cleaning impurities. It can pre-tamp the next tamping point simply during the tamping operation, and at the same time, it can clean the sundries on the soil surface. Through the pre-tamping treatment, the tamping effect during subsequent formal tamping can be effectively improved. At the same time, cleaning the sundries can effectively avoid the unevenness of the soil surface after tamping caused by the sundries, and prevent the sundries from damaging the tamping surface of the equipment, thereby improving the overall construction efficiency.

[0017] 2. By setting multiple tamping mechanisms, the present invention can achieve the purpose of multiple tamping. Through the mechanical cooperation of multiple structures, the effect of continuous multiple tamping can be formed, which can effectively improve the overall operation efficiency and tamping effect of the equipment, greatly shorten the overall construction time, and at the same time make the subgrade soil surface after tamping more compact and beneficial to subsequent construction, thereby improving the construction efficiency and ensuring the tamping effect.

Thus, pre-tamping can be effectively carried out. Simply tamping the soil surface flat is beneficial to subsequent formal tamping, which can improve the tamping effect during formal tamping. At the same time, it helps to shorten the tamping time and improve work efficiency.

[0025] The bottom of the travel plate 2202 is fixedly installed with a screw rod 2203. The number of screw rods 2203 is two. The inner wall of the inner ring of the bearing sleeve 2207 is fixedly connected with a rod seat pipe 2204. The inner wall of the rod seat pipe 2204 is fixedly connected with a mating block 2209.

[0026] By setting the cooperation of the pre-tamping unit 21 and the cleaning unit 22, the purpose of pre-tamping and cleaning impurities can be achieved. It can simply tamp the next tamping point in advance during the tamping operation, and at the same time, it can clean the sundries on the soil surface.

At the same time, the power of the up and down movement of the tamping block 2102 can be used to drive the pressing plate 2201 to move up and down. When the pressing plate 2201 moves, it will drive the travel plate 2202 to reciprocate along the long slot 2208 on the base plate 2206. During the movement, it drives the screw rod 2203 to move up and down reciprocally. The screw rod 2203 will be linked with the mating block 2209 and the mating groove hole 2210 in the rod seat pipe 2204, which can make the rod seat pipe 2204 drive the cleaning rake 2205 to rotate on the base plate 2206 through the bearing sleeve 2207, thereby realizing sundries cleaning and at the same time being able to break up the mud blocks, which can avoid the sundries affecting the tamping effect of the subgrade soil surface.
