Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to an electrically driven road compaction device. Background Technology

[0002] An electrically driven road compactor is a device that uses electricity as a power source to compact road surfaces. It typically consists of an electric motor, a transmission system, a tamping hammer, and a control system. The electric motor provides power, which is transmitted to the tamping hammer through the transmission system, causing the hammer to move up and down to compact the road surface.

[0003] When existing electrically driven road compaction devices are in use, if the battery pack fails, maintenance and replacement are required. This usually involves a complex disassembly of the entire device, which consumes a lot of time and has high maintenance costs. Moreover, during the road compaction process, the battery pack is prone to resonance with the frame and is subjected to severe impact forces, which reduces the stability of the battery. Utility Model Content

[0004] This disclosure relates to an electrically driven road compaction device. By loosening the locking nut at the bottom of the connecting bolt, and simultaneously sliding the two connecting bolts upward, the connecting bolts are disengaged from the first and second support blocks. The battery pack is then adjusted downward via the support base plate, allowing it to disengage from the slot. The battery pack can then be pulled backward along the limit frame, enabling direct disassembly for repair or replacement without complex disassembly of the entire device. This improves the ease of use and reduces maintenance costs.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] The main frame 1 has a support frame 101 at the bottom, and the drive motor 7 is fixedly installed on the support frame 101. The main frame 1 has a handrail 102 at the rear.

[0030] The vibratory machine body 2 has a connecting seat 201 at the top, and the connecting seat 201 is fixedly connected to the main frame 1. The vibratory machine body 2 has a folding box 202 at the bottom, and a tamping hammer 203 is provided at the bottom of the folding box 202.

[0031] In this embodiment of the disclosure, such as Figure 3 and Figure 4 As shown, the top of the support base plate 3 is provided with two limiting frames 301, and the two limiting frames 301 are distributed symmetrically from left to right. There are two connecting ears 302 on both the left and right sides of the limiting frame 301, and the connecting ears 302 on both sides are distributed symmetrically. The middle position of the front and rear ends of the support base plate 3 is provided with a first support block 303, and the two first support blocks 303 are distributed symmetrically.

[0032] The bottom of the battery pack 4 is provided with a mounting base 401, and the mounting base 401 is provided with limiting grooves 402 on the left and right sides. The mounting base 401 is slidably connected to the limiting frame 301 of the supporting base plate 3 through the limiting grooves 402.

[0033] The mounting top plate 6 has fixing sleeves 601 at the bottom of both ends, and the fixing sleeves 601 are fixedly fitted onto the main frame 1. The bottom of the mounting top plate 6 has a slot 602, and the top of the battery pack 4 is engaged with the slot 602 of the mounting top plate 6. The middle of the front and rear ends of the mounting top plate 6 has a second support block 603, and the second support block 603 corresponds to the position of the first support block 303. A connecting rod 604 slides through the second support block 603, and the connecting rod 604 also passes through the first support block 303. It is controlled by a locking nut. When the battery pack 4 malfunctions, by loosening the locking nut at the bottom of the connecting rod 604, the two connecting rods 604 are slid upwards, so that the connecting rod 604 is disengaged from the first support block 303 and the second support block 603. The battery pack 4 is then adjusted downwards by the support base plate 3, so that the battery pack 4 can be disengaged from the slot 602. Then, the battery pack 4 can be pulled backwards along the limit frame 301, so that the battery pack 4 can be directly removed for repair or replacement.

[0034] Example 2, based on Example 1, such as Figure 5 As shown, mounting blocks 304 are provided at the middle positions of the left and right ends of the support base plate 3, and the two mounting blocks 304 are distributed symmetrically. A limiting sleeve 305 is provided on the top of the mounting block 304.

[0035] The connecting sleeve 5 is rotatably connected to the main frame 1, and the bottom of the connecting sleeve 5 is provided with a telescopic sleeve rod 501. The bottom end of the telescopic sleeve rod 501 is provided with a connecting block 502, and the connecting block 502 is rotatably connected to the connecting ears 302 of the support base plate 3 through a pin.

[0036] The bottom of the mounting plate 6 is provided with two limiting round rods 605, which are symmetrically distributed from left to right. A restoring spring 606 is fitted on the limiting round rod 605. The bottom end of the limiting round rod 605 is slidably inserted into the limiting sleeve 305, and the restoring spring 606 is supported between the limiting sleeve 305 and the mounting plate 6. In this utility model, the connecting sleeve 5 and the telescopic sleeve 501 are connected between the supporting base plate 3 and the main frame 1. Through the sliding cooperation of the limiting round rod 605 and the limiting sleeve 305, and by utilizing the rebound pulling effect of the restoring spring 606, it is beneficial to keep the battery pack 4 stable during the ground compaction process.

[0037] The working principle of this embodiment is as follows: When the battery pack 4 malfunctions, by loosening the locking nut at the bottom of the connecting bolt 604 and simultaneously sliding the two connecting bolts 604 upwards, the connecting bolts 604 are disengaged from the first support block 303 and the second support block 603. The battery pack 4 is then adjusted downwards by the support base plate 3, allowing it to disengage from the slot 602. The battery pack 4 can then be pulled backwards along the limit frame 301 to directly remove it for repair or replacement. The connecting sleeve 5 and the telescopic sleeve 501 are connected between the support base plate 3 and the main frame 1. The limit round rod 605 and the limit sleeve 305 slide and engage, and the rebound pull of the return spring 606 helps to keep the battery pack 4 stable during the ground compaction process.
