Description

Technical Field

[0001] This invention relates to the field of building foundation construction technology, specifically to a low-carbon and environmentally friendly electric compactor for building foundation construction. Background Technology

[0002] During foundation construction, the ground needs to be leveled and compacted, requiring the use of compaction machines. Small, hand-operated compaction machines are suitable for locations where large equipment is difficult to operate, making them the most widely used compaction equipment. However, current market offerings of this type of compaction equipment suffer from several problems. For example, they cannot adjust the impact force of the compaction plate according to specific compaction needs; they cannot effectively reduce the physical exertion of operators in lightweight applications; and they cannot effectively control construction dust to avoid air pollution and reduce health risks for operators. Furthermore, in pursuit of low-carbon and environmentally friendly practices, electric compaction machines have begun to be used. However, these machines are prone to malfunction due to the frequent vibrations caused by existing energy storage devices such as batteries or lithium batteries installed on them. Therefore, these machines generally require external power supply via cables, limiting their application.

[0003] If a new type of compactor can be invented that allows for easy adjustment of the working mode according to the needs of compaction work, reduces dust, minimizes physical exertion on operators, and avoids malfunctions of the power storage equipment caused by vibration, such problems can be effectively solved.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the technical solutions of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Please see Figures 1 to 4This invention provides a technical solution: a low-carbon and environmentally friendly electric compactor for building foundation construction, comprising a frame 1, on which a main motor 19 is fixedly mounted, and the output end of the main motor 19 drives a lifting slide rod 23 that can be raised and lowered via an eccentric wheel 20. A compaction plate 25 for compaction operations is fixedly mounted at the bottom of the lifting slide rod 23, and the compaction plate 25 is fixedly mounted to the lifting slide rod 23 by detachable bolts. The handle 9 has an L-shaped interface, and the handle 9 is fixedly mounted at the rear end of the frame 1 for convenient... The operator holds the handle 9 to control the movement direction of the compactor. A control switch 8 is fixedly installed on the handle 9. A pair of sliding connecting rods 21 are fixedly installed below the handle 9. The lower part of the sliding connecting rods 21 is closed by a screw-in limit ring 22.

An energy storage device 10 and a controller 16 are fixedly installed on the shock-absorbing mounting seat 15. A support roller 17 is installed below the shock-absorbing mounting seat 15. A dustproof device 6 covering the compaction plate 25 is provided at the bottom of the frame 1.

[0026] Please see Figures 1 to 4 The front end of the frame 1 is equipped with a dust collection device 5, and the rear end of the frame 1 is equipped with a dust suppression device 7. An elastic protective ring 24 for dust prevention is provided between the frame 1 and the compaction plate 25. A lifting handle 11 for easy transport of the compactor is fixedly installed at the upper end of the frame 1. Side drive devices 3 for driving the frame 1 are respectively provided at the left and right ends of the frame 1 via adjustment devices 4. The controller 16 is electrically connected to the control switch 8, the main motor 19, the side drive devices 3, the dust collection device 5, the dust suppression device 7, and the energy storage device 10. The controller 16 is an ARM single-chip microcomputer controller. Switch 8 is a rocker switch or a membrane switch.

For example, whether the dust removal device 5 removes dust, whether the dust suppression device 7 suppresses dust, and whether the side drive device 3 is working. The energy storage device 10 can use lithium batteries or storage batteries according to the usage requirements. At the same time, the shock absorption mounting base 15 is also equipped with a rectifier and inverter that are electrically connected to the energy storage device 10, which facilitates the conversion of external AC power into DC power that is easy to store in the energy storage device 10.

[0027] Please see Figures 1 to 3The dustproof device 6 includes a cover 605 fixedly installed at the bottom of the frame 1 and used to cover the tamping plate 25.

[0028] Please see Figure 1 , Figure 2 and Figure 4 The side drive device 3 includes a lifting frame 303 slidably mounted to the side of the frame 1, and a caster wheel 304 is fixedly mounted at the rear end of the lifting frame 303. A drive roller 302 is mounted at the front end of the lifting frame 303 via a bearing, and a drive motor 301 for driving the drive roller 302 via a belt or chain is fixedly mounted on the lifting frame 303. The drive motor 301 is electrically connected to the controller 16. The adjustment device 4 includes a sliding rod 401 slidably mounted to the frame 1, and the end of the sliding rod 401...

The first end of the sliding rod 401 is fixed on the pull seat 404, and a pair of limit rods 403 are fixedly installed on the pull seat 404. The lifting frame 303 has at least two pairs of limit holes at different heights that cooperate with the limit rods 403 for insertion and fixing. The top of the lifting frame 303 is fixedly installed with a handle 18. By adjusting the installation height of the side drive device 3 on the frame 1, the compactor can switch between two different working modes.

[0029] Please see Figures 1 to 3 The dust removal device 5 includes a filter device 502 fixedly installed on the frame 1, a dust collection device 503 and an air pump 504. The outlet end of the filter device 502 is provided with an exhaust pipe 501 for exhausting air. The inlet end of the filter device 502 is connected to the outlet end of the dust collection device 503, and the inlet end of the dust collection device 503 is connected to the outlet end of the air pump 504. The inlet end of the air pump 504 is connected to an air suction nozzle 505 installed above the compaction plate 25. The air pump 504 is electrically connected to the controller 16. The dust removal device 3 is used to remove dust generated by the compaction plate 25 hitting the ground and to collect the dust.

[0030] Please see Figure 2 and Figure 3 The dust suppression device 7 includes a water pump 701 and a mounting ring 702, which are fixedly installed. The inlet end of the water pump 701 is connected to an external water supply device through a water pipe. The mounting ring 702 is equipped with an atomizing nozzle 703 that is connected to the water pump 701. The water pump 701 is electrically connected to the controller 16. The dust suppression device 7 can spray atomized water onto the dust through an external water pipe to achieve the purpose of dust suppression.

[0031] In this embodiment, the compactor can operate in two modes: the first is a self-traction mode, in which the two side drive devices 3 are adjusted by the operator to the lowest position of the frame 1. At this time, the drive rollers 302 and casters 304 on the side drive devices 3 are in contact with the ground, while the compaction plate 25 is not in contact with the ground at its highest point. When the compaction plate 25 is in contact with the ground at its lowest point, the drive rollers 302 and casters 304 can also maintain contact with the ground. At this time, when the operator turns on the drive motor 301 on the drive device 3, the drive motor 301... The drive roller 302 will rotate, causing it to move the compactor forward automatically. When the main motor 19 drives the compaction plate 25 for compaction, the operator only needs to follow the compactor. The compactor can move along a straight line, and the operator only needs to adjust the direction of movement as needed, greatly reducing the operator's physical exertion. However, because the travel distance of the compaction plate 25 is shortened in this mode, the compaction effect of the compaction plate 25 on the ground is reduced, making it only suitable for compaction where necessary. In low-intensity or simple leveling applications, and given the minimal vibration, the vibration damping mount 15 can be directly placed on the frame 1 and secured with the mating screws 13. The second mode is manual operation. In this mode, the side drive unit 3 is pulled upwards and installed at the highest position on the frame 1. The drive cope wheel 302 and caster wheel 304 will no longer contact the ground; only the compaction plate 25 will contact the ground and support the entire compactor. During compaction, the operator needs to manually hold the handle 9. To prevent the compactor from tipping over, the operator's physical exertion is relatively high. However, since the compaction plate 25 can always impact the ground at its maximum stroke, it has the best compaction effect. In this mode, the shock-absorbing mounting base 15 should be placed on the ground. This way, when the compactor vibrates, the vibration will be transmitted to the energy storage device 10 and controller 16 located on the mounting base 15 to a minimum, thereby greatly reducing the failure of the energy storage device 10 or controller 16 caused by vibration. At this time, the shock-absorbing mounting base 15 can move with the frame 1 under the push of the sliding connecting rod 21.During the operation of the compactor, the dust generated by the impact of the compaction plate 25 on the ground is confined to the inside of the cover 605 to the maximum extent. When the compaction plate 25 moves up and down, the debris-pushing ring 604 at the bottom of the cover 605 can contact the ground to the maximum extent under the action of the buffer spring 601. At the same time, the debris-pushing ring 604 can also effectively push away debris. The dust inside the cover 605 will be sucked up by the suction nozzle 505 driven by the air pump 504, and then intercepted and collected in the dust collection device 503 by structures with adsorption properties such as activated carbon, sponge or cotton. The filter device 502 is also equipped with dust collection bags and other dust removal and filtration equipment to perform final treatment of the dust, thereby effectively preventing dust from entering the air. When dust overflows into the air from the bottom of the dust prevention device 6, the water pump 701 can also drive the atomizing nozzle 703 to atomize and spray the air, thereby removing dust from the air, effectively reducing construction dust, and protecting the environment and the health of operators. The compactor can be powered by an external cable or by a separate power supply from the energy storage device 10, thus freeing it from the constraints of cables and enabling its application in a wider range of construction scenarios.

[0032] Example 2

[0033] Please see Figure 5 and Figure 6 Compared to Embodiment 1, this embodiment further includes a pair of counterweight devices 2 stacked on the side of the frame 1. Each counterweight device 2 includes a mounting bracket 204 for mounting counterweight plates 205. A sliding block 201 is fixedly mounted on the top of the mounting bracket 204, and a sliding guide rail 26 for slidingly mounting the sliding block 201 is fixedly mounted on the frame 1. The top of the mounting bracket 204 is fixedly mounted to the frame 1 by positioning bolts 202, and a rubber support foot 206 for cushioning and shock absorption is fixedly mounted on the bottom of the mounting bracket 204. 06 is used to reduce the impact force of the counterweight device 2 on the ground when the device is removed from the frame 1 and placed on the ground, especially to avoid injuring the operator's feet. The side of the mounting frame 204 is fixedly installed with a side handle 203 for carrying the counterweight device 2. The counterweight plate 205 on the counterweight device 2 can be freely replaced and adjusted to the corresponding weight. By adjusting the counterweight of the counterweight device 2, the self-weight of the equipment can be effectively adjusted, thereby adjusting the impact force brought by the weight of the compactor, effectively meeting different ground compaction needs.
