Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aerial work vehicles, in particular to an aerial work vehicle with an anti-dumping structure. Background Art
[0002] Aerial work vehicles are equipment that provide high-altitude reach capabilities and are applicable to outdoor construction, large equipment installation, building surface cleaning, infrastructure maintenance and other occasions that require high-altitude operations. When in use, it is necessary to open the hydraulic support legs to support the vehicle body to prevent problems such as uneven weight distribution and unstable chassis from tipping over when the aerial work vehicle is operating at a higher position.
[0003] Aerial work vehicles in the prior art are generally equipped with four hydraulic support legs, each of which can be upgraded, extended and raised and lowered individually. The bottom of the hydraulic support leg is provided with a bottom plate that directly contacts the ground to increase the contact area with the ground, but the bottom plate and the hydraulic support leg are fixedly connected. The support points of the four hydraulic support legs are spaced relatively far apart, and there may be a phenomenon that the ground at the support position of some hydraulic support legs is uneven or the ground is soft. The bottom plate is fixedly connected to the hydraulic support leg, and the uneven ground will lead to a reduction in the contact area between the bottom plate and the ground, resulting in differences in the heights of the four support legs, resulting in different balance points for each, which can easily cause the aerial work vehicle to shake or even tip over during operation. Utility Model Content
[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides an aerial work vehicle with an anti-dumping structure.
[0005] The technical solution of this utility model is as follows:

[0007] The anti-dumping unit includes a connecting frame which is detachably connected to the rectangular groove, and its length direction is consistent with the length direction of the rectangular groove. A retractable auxiliary support leg group is arranged inside the connecting frame. The upper part of the auxiliary support leg group is rotatably connected to the connecting frame, and the lower end of the auxiliary support leg group can be rotated to the side away from the connecting frame and can be extended to the ground to contact it.
[0008] The anti-dump unit is detachably connected to the leg body, and can be selectively installed on any vertical side of the leg body according to the inclination of the hydraulic support leg to compensate for the sinking or tilting of one side of the hydraulic support leg. The anti-dump unit is easy to install and disassemble, and its extended length can be easily adjusted. The lower end of the auxiliary support leg group can increase the contact area between the hydraulic support leg and the ground, thereby improving the stability of the aerial work vehicle during operation.
[0009] The specific structure of the auxiliary support leg group is that the auxiliary support leg group includes a first support frame rotatably connected to the upper part of the connecting frame, and a retractable support leg is slidably connected to the first support frame along its length direction and is detachably connected to the retractable support leg.
[0010] Regarding the connection method between the connecting frame and the supporting body, the connecting frame is magnetically attracted to the bottom surface of the rectangular groove through a magnetic attraction part. The magnetic attraction method is an electromagnet magnetic attraction method, and the magnetic force is adjustable, which increases the stability of the connection between the connecting frame and the leg body.
[0011] The specific structure of the above-mentioned magnetic attraction component is that the magnetic attraction component is two permanent magnets, which are arranged at both ends of the connecting frame along the length direction. The permanent magnets have magnetic end faces, which are flush with one side of the connecting frame close to the rectangular groove and are magnetically connected to the rectangular groove.
[0012] The retractable support leg can slide along the length direction of the first support frame toward the ground. Specifically, a slide is provided along the length direction on one side of the first support frame away from the rectangular groove, the bottom of the slide is open, and the retractable support leg is slidably connected in the slide.
[0013] The installation positions of the two permanent magnets are such that one of the permanent magnets is located above the first support frame and the other permanent magnet does not interfere with the auxiliary support leg group. The installation positions of the two permanent magnets are far apart, so that the two ends of the connecting frame can be stably fixed on the leg body.
[0014] Regarding the connection method between the first support frame and the telescopic support leg, the lower part of the first support frame is threadedly connected with a fastener, and the upper part of the telescopic support leg is provided with a connecting hole that cooperates with the fastener, and one end of the fastener can be connected to the connecting hole.
[0015] In order to increase the contact area between the lower end of the telescopic supporting leg and the ground, the lower end of the telescopic supporting leg is an output end, and the output end is hinged with a supporting bottom plate.
[0016] The beneficial effect of the utility model is that the connecting frame is connected to the leg body by an electro-permanent magnetic attraction, which not only facilitates the anti-dumping unit to adjust the height in any direction of the hydraulic support leg, preventing one or more of the four hydraulic support legs from tilting to one side, but also facilitates the anti-dumping unit to be quickly installed and disassembled on different sides of the leg body;
[0017] The retractable supporting legs are electric hydraulic cylinders or other retractable devices that can withstand a large load. After the first supporting frame is rotated to a suitable angle, the retractable supporting legs are slid downward along the slide of the first supporting frame for a certain length as a whole, and the upper part of the retractable supporting legs is fixed to the first supporting frame by fasteners. Then, according to the inclination angle of the hydraulic supporting legs, the retractable supporting legs are controlled to extend toward the ground and press against the ground. The retractable supporting legs of the anti-dumping unit cooperate with the cylinder legs of the hydraulic supporting legs to form a support, thereby correcting the tilted hydraulic supporting legs. At the same time, the contact area between the hydraulic supporting legs and the ground improves the stability of the aerial work vehicle during operation and has an anti-dumping effect.
