Description

Technical Field

[0001] The invention belongs to the technical field of earth backfilling and compacting, and specifically refers to an earth backfilling and compacting device for building construction. Background Art

[0002] With the acceleration of urbanization and the continuous advancement of infrastructure construction, the market demand for earth backfill construction for housing construction is increasing. As a key tool to ensure the quality of backfill soil and improve construction efficiency, the importance of earth backfill compaction devices is becoming increasingly prominent.

[0003] The existing earth backfill compaction device has the following problems:

[0004] The compaction speed of the existing backfill compaction device is slow. After the compaction component falls, it takes a lot of energy to reset to a high position again due to its large weight, and the reset speed when resetting to the high position is slow, which affects the overall work progress of the backfill area. The traditional backfill compaction device does not have the ability to guide, and the equipment is prone to deviation during compaction operations, resulting in uneven compaction of the soil in the backfill area. Therefore, it cannot meet the existing use requirements of the backfill compaction device. Summary of the invention

[0008] When in use, the height adjusting plate and the locking pad are rotated forward respectively, the height adjusting plate and the locking pad rotate and rise along the guide column, the distance between the height adjusting plate and the tamping table increases, and the locking pad is rotated reversely, the locking pad rotates along the guide column and fits tightly together with the height adjusting plate, the height adjusting plate changes from an active state to a fixed state, the tamping spring is in an extended setting in a normal state, and the conical table drives the spring plate to slide and descend along the guide column under its own gravity, and the spring plate compresses the tamping spring. At this time, the conical table fits the surface of the ground, and when the backfilling part is compacted, the driving electromagnet is energized to generate magnetism, the driving electromagnet and the tamping magnet are set with opposite poles, and the driving electromagnet is fixed to the bottom wall of the driving frame and the tamping magnet is adsorbed by magnetic force. The tamping magnet drives the conical table to rise through the spring plate, and the conical table maintains a maximum distance from the ground, and then the driving electromagnetic The body is powered off and demagnetized, and the compacting magnet, without the attraction of magnetic force, drives the conical table to fall freely through the spring plate, and the conical table compacts the backfill area with its own gravity. When the compression degree of the compacting spring is in place, the bottom wall of the spring plate fits with the limit rod, thereby avoiding excessive compression of the compacting spring. By limiting the limit rod, on the one hand, the compacting depth of the conical table can be limited, and on the other hand, the compression amount of the compacting spring can be limited. After the conical table reaches the compaction depth, the compacting spring is in the maximum compression state. At this time, the rebound force of the compacting spring is the maximum value, and the conical table tends to move upward away from the ground under the reset force of the compacting spring, driving the electromagnet to be energized to generate magnetism, thereby adsorbing the conical table to the highest point away from the ground, so that the conical table can be free-fall again to compact the backfill area.

[0009] Preferably, the fixed-point mechanism includes a fixed-point frame, a disassembly bolt and a fixed rope wheel, the fixed-point frame is arranged at one end of the mobile platform away from the mobile platform, the disassembly bolts are symmetrically arranged on both sides of the fixed-point frame, the end of the disassembly bolt away from the fixed-point frame is arranged inside the mobile platform, the disassembly bolt is threadedly connected to the mobile platform, and the fixed rope wheel is arranged at one end of the fixed-point frame away from the mobile platform; the travel drive mechanism includes a dual-axis drive motor, a drive shaft and a walking wheel, the dual-axis drive motor is symmetrically arranged on the inner walls at both ends of the mobile platform, and the walking wheels are symmetrically arranged on the mobile platform in pairs. On both sides of the moving platform, the walking wheels are rotatably connected to the moving platform, and the driving shaft passes through the moving platform and is arranged between the walking wheels and the power end of the dual-axis driving motor; the rope winding mechanism includes a rope winding frame, a rope winding drum, a rope winding motor and a wire rope, the rope winding frame is arranged on the bottom wall of the moving platform, the rope winding drum is rotatably arranged on the inner wall of the rope winding frame, the rope winding motor is arranged on the side wall of the rope winding frame, the power end of the rope winding motor passes through the rope winding frame and is connected with the rope winding drum, the wire rope is wound around the outside of the rope winding drum, and the end of the wire rope away from the rope winding drum passes through the moving platform and is arranged on the outside of the fixed rope wheel.

[0010] When in use, in order to prevent the cone table from deviating during the compaction operation, resulting in uneven compaction inside the backfill area, the disassembly bolts are rotated and unscrewed from the inside of the mobile platform, and the fixed-point frame is removed from the side wall of the mobile platform. The fixed-point frame drives the fixed rope wheel to be fixed on the edge of the backfill area, and the power ends on both sides of the dual-axis drive motor drive the drive shaft to rotate, and the drive shaft drives the walking wheel to drive the mobile platform to move. The speed of the rope winding motor is lower than that of the dual-axis drive motor. The rope winding motor drives the rope winding drum to unwind at a slower speed through the power end, and the mobile platform travels at a faster speed, making The wire rope is always in a straightened state. When the conical table is in free fall to compact the backfill area, the compression of the tamping spring by the conical table causes the conical table to indirectly cause an impact force on the tamping table. By utilizing the opposite elastic force of the tamping spring, the rise of the conical table can be accelerated, thereby speeding up the tamping operation in the backfill area. The impact force caused by the conical table on the tamping table may cause the rear wheels of the mobile table to lift up, thereby causing a safety accident. Under the action of the straightened wire rope, the probability of the rear wheels of the mobile table being lifted up can be reduced, thereby ensuring the safety of the tamping operation.

[0011] Specifically, the energy storage type supply mechanism includes a diesel generator, an energy storage power supply and a rectifier. The diesel generator is arranged inside the power supply box, and the energy storage power supply and the rectifier are respectively arranged on the side walls of the power supply box.

[0012] When in use, the electricity generated by the diesel generator is integrated through the rectifier and then fed into the energy storage power supply for storage. The energy storage power supply provides power for the compaction operation of the equipment.

[0013] Wherein, the rectifier is electrically connected to the diesel generator and the energy storage power supply.

[0014] Preferably, a controller is provided on the side wall of the power supply box.

[0015] Furthermore, the controller is electrically connected to the driving electromagnet, the dual-axis driving motor and the diesel generator respectively.

[0016] Furthermore, the model of the controller is SYC89C52RC-401.

[0017] The beneficial effects achieved by adopting the above structure are as follows:

[0018] Compared with the prior art, the present invention adopts a combination of an elastic limiting structure and a guiding unwinding structure. By setting a thickness-limiting spring-pressing mechanism, a weight-increasing guiding mechanism and an energy storage supply mechanism, the present invention can accelerate the resetting speed of the conical platform and shorten the compaction progress of the earth backfilling area caused by the free fall of the conical platform under the coordinated use of the limiting mechanism, the spring-driving mechanism, the compacting magnet, the fixed-point mechanism, the driving mechanism and the winding rope mechanism. The steel wire rope can press and guide the mobile platform against the ground to ensure that the mobile platform will not lift the wheels under the free fall impact of the conical platform, and can place the mobile platform The platform deviates during the movement, reducing the probability of uneven compaction in the backfill area. The speed of the rope winding motor is lower than that of the dual-axis drive motor. The rope winding motor drives the rope winding drum to unwind at a slower speed through the power end, and the mobile platform travels at a faster speed, so that the wire rope is always in a straightened state. When the conical platform compacts the backfill area in free fall, the compression of the compaction spring by the conical platform indirectly causes an impact force on the compaction platform. By utilizing the opposite elastic force of the compaction spring, the rise of the conical platform can be accelerated, thereby speeding up the compaction operation in the backfill area.

[0041] The model of the controller 38 is SYC89C52RC-401.

[0042] When in use, in Example 1, the height adjustment plate 7 and the locking pad 8 are rotated forward respectively, and the height adjustment plate 7 and the locking pad 8 are rotated and raised along the guide column 6, and the distance between the height adjustment plate 7 and the tamping table 2 increases.

[0046] Embodiment 3, this embodiment is based on the above embodiment. In order to avoid the deviation of the conical platform 19 during the compaction operation, resulting in uneven compaction inside the earth backfill area, the disassembly bolt 24 is manually rotated, and the disassembly bolt 24 is unscrewed from the inside of the mobile platform 1, and the fixed point frame 23 is taken down from the side wall of the mobile platform 1.

The controller 38 controls the rope winding motor 33 to start, and the rotation speed of the rope winding motor 33 is less than the rotation speed of the dual-axis drive motor 27. The rope winding motor 33 drives the power end The rope drum 32 is unwound, and the unwinding speed of the rope drum 32 is slow. The moving platform 1 travels at a fast speed. The wire rope 39 is always in a straightened state. When the conical platform 19 is in free fall to compact the earth backfill area, the conical platform 19 compresses the tamping spring 15, so that the conical platform 19 indirectly causes an impact force on the tamping platform 2. By utilizing the opposite elastic force of the tamping spring 15, the rise of the conical platform 19 can be accelerated, thereby speeding up the tamping operation in the earth backfill area. The impact force caused by the conical platform 19 on the tamping platform 2 has a probability of driving the rear wheels of the moving platform 1 to lift, thereby causing a safety accident. Under the action of the straightened wire rope 39, the probability of the rear wheels of the moving platform 1 being lifted can be reduced, thereby ensuring the safety of the tamping operation. The above operation can be repeated the next time it is used.
