Abstract

The invention relates to a pavement compacting vehicle. A compacting device is arranged at the lower part of a vehicle chassis, and an engine drives an eccentric balance weight capable of sliding freely along a rotating shaft to rotate, so that the balance weight is constantly lifted and then slides during the moving process of the vehicle to continuously hammer the ground so as to compact a pavement. Compared with the traditional compacting device, the pavement compacting vehicle has the advantages that the use is simpler, the compacting efficiency is higher, and the more energy is saved as only one engine is used to supply energy.

The slider is fixedly connected to the rotating shaft. body, the counterweight body is provided with two grooves greater than the width of the slider, the length of the grooves is at least twice the length of the slider, and the grooves are arranged symmetrically with respect to the axis of the counterweight body, The length axis of the groove is parallel to the longitudinal axis of the counterweight body, the geometric center of the groove is located on the transverse center section of the counterweight body, and the pair of sliders are symmetrically arranged in the groove and slidably connected with the groove;

The counterweight body is also provided with a strip-shaped through-hole in cross-section relative to the groove, the bus axis of the through-hole coincides with the longitudinal axis of the groove, and the width of the through-hole is larger than the diameter of the rotating shaft and smaller than that of the slider. The width of the through hole is equal to the length of the groove;

The length of the counterweight body is A, the height of the rotating shaft from the ground is B, and the length of the groove is C, wherein 2B≤A+C.

The rotating shaft is rotatably fixed on the chassis, and the rotating shaft is rotatably connected to the transmission device of the vehicle engine. When the rotating shaft rotates, the slider and the groove cooperate to make the counterweight rotate synchronously under the drive of the rotating shaft. When the center of gravity of the counterweight body deviates, the weight of the counterweight body drives the slider to slide in the groove.

As a further innovation of the present invention, the inside of the counterweight body is a hollow structure, and the hollow structure is filled with liquid or solid particles.

As a further innovation of the present invention, the tamping device also includes a boom, the boom is fixed on the chassis, one end of the rotating shaft is rotatably connected to the chassis, and the other end of the rotating shaft rotates with the boom connect.

Beneficial effect:

In the present invention, a tamping device arranged at the lower part of the vehicle chassis is driven by an engine to rotate a freely movable eccentric weight body, so that the weight body is continuously lifted and then slid down during the driving process of the vehicle, hammering the ground, and The compaction of the road surface; compared with the traditional compaction equipment, the present invention is easier to use and has higher compaction efficiency, because only one engine is needed for power supply, so it is more energy-saving.

Detailed ways

Do further description below in conjunction with accompanying drawing:

As shown in Figure 1, the present invention is a kind of road compacting vehicle, and the effective structure of road compacting vehicle is the compacting device that is arranged in the middle of the wheel 2 of vehicle, and described compacting device is fixed on the chassis 1, and described compacting device consists of several It consists of cylindrical counterweights 3 symmetrically distributed on both sides of the vehicle chassis 1. The tamping device also includes a number of rotating shafts 6. Two sliders 5 are fixedly connected to the rotating shafts 6. The central positions of the counterweights 3 are symmetrical. Two grooves 4 equal in width to the slider 5 are provided, the axes of the grooves 4 are parallel to the central axis of the counterweight body 3, and the length of the grooves 4 is three times the length of the slider 5. The block 5 is slidably connected with the groove 4, and a strip-shaped through hole for the rotation shaft 6 to move is also provided in the position of the groove in the counterweight body 3. When the slider 5 moves in the groove 4, the strip The through hole provides a moving space for the accompanying movement of the rotating shaft 6. The counterweight body 3 is also filled with sand, and the filling amount of the sand is 3/5 of the volume of the counterweight body 3 cavity. Rotationally stable suspender 7, one end of the suspender 7 is rotationally connected to the rotating shaft 6 to prevent the breaking of the rotating shaft 6 due to the excessive weight of the counterweight 3 and the excessive bending moment at the connection with the chassis; the length of the counterweight 3 The relationship between A and the height B from the ground of the rotating shaft 6 and the length C of the groove 4 is 2B≤A+C, so as to prevent the ineffective stroke of the counterweight 3 from being too long to affect the rotation, or the stroke of the counterweight 3 is too short, or The length of the counterweight body 3 is too short, causing the counterweight body 3 to be unable to touch the ground, thus achieving a good compaction effect;

During operation, the rotating shaft 6 is connected to the transmission mechanism of the vehicle to supply energy. When the rotating shaft 6 rotates, the slider 5 cooperates with the groove 4, so that the counterweight 3 rotates synchronously under the drive of the rotating shaft 6. When the center of gravity of the weight body 3 shifts due to the movement of the filler, the weight of the weight body 3 drives the slider 5 to slide in the groove 4. When the weight body 3 rotates to the highest position, due to the action of gravity, the weight body 3 quickly vertically slide down on the ground, so that the counterweight 3 hammers the ground to compact the ground;

The invention has the tamping efficiency that the traditional tamping machine does not have, greatly simplifies the operation difficulty, shortens the construction period, reduces the cost, and has good social and economic benefits.
