Description

Technical Field

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

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

[0003] ‌Road subgrade tamping‌ refers to the treatment of the road subgrade through tamping and compaction techniques 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 prolong the construction period, and the low tamping efficiency is also likely to result in a poor tamping effect. Therefore, we propose a road subgrade tamping device and a tamping method.

[0004] Combining the above problems, we will find that the existing road subgrade tamping devices on the market are difficult to avoid the above-mentioned problems simultaneously during use. And even if they can be solved, external tools need to be used in cooperation, thus failing to achieve the desired effect. Therefore, we propose a road subgrade tamping device and a tamping method.

[0019] A ramming method for a roadbed ramming device includes the following steps:

[0020] 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;

[0021] 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 seat. The main rammer hammers the rammer seat 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;

[0022] 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.

The eccentric wheel drives the ramming block to directly strike the roadbed soil surface for pre-ramming, which can make the ramming effect better during subsequent formal rammings;

[0024] S5: Meanwhile, the power generated by the reciprocating movement of the ramming block up and down can be utilized to drive the pressing plate to move up and down. When the pressing plate moves, it will drive the stroke plate to reciprocate, and at the same time drive the screw rod to reciprocate up and down. The screw rod will be linked and cooperated with the matching block and the matching slot hole 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 the cleaning of sundries. At the same time, the mud blocks can be broken up, which can avoid the sundries from affecting the ramming effect of the subgrade soil surface.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. By setting the cooperation of the pre-ramming unit and the cleaning unit, the present invention can achieve the purpose of pre-ramming and cleaning impurities. It can pre-ram the next ramming point simply during the ramming operation, and at the same time can clean the sundries on the soil surface. Through the pre-ramming treatment, the ramming effect during subsequent formal ramming can be effectively improved. At the same time, cleaning the sundries can effectively avoid the unevenness of the soil surface after ramming caused by the sundries, and prevent the sundries from damaging the ramming surface of the equipment, thereby improving the overall construction efficiency.

[0027] 2. By setting multiple ramming mechanisms, the present invention can achieve the purpose of multiple rammings. Through the mechanical cooperation of multiple structures, the effect of continuous multiple rammings can be formed, which can effectively improve the overall operation efficiency and ramming effect of the equipment, greatly shorten the overall construction time, and at the same time make the subgrade soil surface after ramming more compact and beneficial to subsequent construction, thereby improving the construction efficiency and ensuring the ramming effect.

After a series of inspections, the body (1) is placed on the area to be tamped and the tamping operation is started; S2: Then the hydraulic assembly (12) on the machine body (1) is started, and the hydraulic assembly (12) drives the main rammer (15) to reciprocate and hammer the rammer seat (14) up and down, and the main rammer (15) reciprocates and hammers the rammer seat (14) multiple times, and the roadbed soil surface is rammed by the impact of the main rammer (15) and the weight of the machine body (1); S3: In order to enhance the tamping effect and improve the working efficiency during the tamping operation, the force of the main tamping hammer (15) moving up and down can be used to cooperate with the tooth plate (305) and the wide gear (304) meshing therewith, and then drive multiple auxiliary tamping hammers (309) to tamp up and down in an interlaced manner through the crankshaft (303), thereby achieving the purpose of multiple tamping, which can enhance the tamping effect and improve the working efficiency; S4: In addition, while performing multiple tamping, the rotational force of the crankshaft (303) can be used to drive the tamping block (2102) to perform pre-tamping.
