Description

Technical Field

[0001] The utility model belongs to the technical field of logistics climbing vehicles, in particular to a double-layer climbing vehicle. Background Art

[0002] The prior art discloses a double-decker climbing vehicle (CN202220986879.1), which includes a lower plate, an upper plate, directional rubber wheels, universal rubber wheels, a spring climbing ladder, a steel main frame, an auxiliary bracket and an anti-slip handrail. The front end of the bottom of the lower plate is provided with a directional rubber wheel, and the rear end of the bottom is provided with a universal rubber wheel. The upper plate and the lower plate are parallel to each other, and they are supported and connected by the steel main frame and the auxiliary bracket. The two ends of the anti-slip handrail are respectively fixed on the upper plate and the steel main frame. The spring climbing ladder is arranged between the two steel main frames and can move up and down with the increase or decrease of weight.

[0003] After searching, it was found that the device did not clearly consider the storage of workers' tools during climbing operations. If the workers forgot to take the tools, they would need to leave the climbing vehicle. In addition, there was no clear way to pull the folded climbing vehicle, which was not convenient to move. It would affect carrying after storage. At the same time, the device used additional support plates to support the upper and lower plates. If the support plates were forgotten, the climbing vehicle could not be fixed. At the same time, due to the use of directional rubber wheels and universal rubber wheels, if the brakes were forgotten before climbing operations, the climbing vehicle would slip and could not maintain stability.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0011] As one preferred embodiment of the utility model, a limiting seat is rotationally connected to each side of the bottom plate and the ladder, and a support is rotationally connected to each side of the upper plate and the ladder.

[0012] As one preferred embodiment of the utility model, the top of the support handle is provided with a semicircular ring handle for dragging, and the center of the semicircular ring handle is a square with the same width as the upper plate.

[0013] As one preferred embodiment of the utility model, a groove for assisting the rotation of the wheel is formed in the inside of the fixing block, a shaft rod for rotation is arranged in the groove, and the wheel is rotationally connected to the fixing block through the shaft rod.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. The threaded rod is driven by the upper rotating handle disc to slide the storage basket on the side plate, so that the upper and lower lifting is realized, the storage and taking of tools during the climbing operation of the staff are facilitated, and the staff needs to leave the climbing vehicle when forgetting to take the tools.

[0016] 2. The support handle rotationally connected to the bottom plate is rotated to the appropriate position, then the clamping block on both sides of the upper plate is clamped and locked to the second clamping hole, and then the semicircular ring handle above the support handle is used to realize the pulling of the climbing vehicle, so that the climbing vehicle is conveniently moved.

[0017] 3. The side plate is folded with the upper plate by the connecting seat, and can be stored. At this time, the height of the fixed block is just above the ground after the side plate is folded. At this time, the wheels just contact the ground and slide on the ground to achieve the purpose of movement. In addition, the side plate can be vertically erected on one side of the upper plate through the connecting seat during the climbing operation. In addition, the fixed blocks fixed on both sides of the side plate will contact the ground, so that the side plate can be more stably fixed on the ground. At this time, the wheels rotatingly connected in the inside will be suspended from the ground due to the stable placement of the fixed blocks, ensuring the stability of the climbing vehicle during the climbing operation. Such design is to ensure that the climbing vehicle does not slip due to the universal wheel being stuck or forgetting to lock the brake during the climbing operation of the device, ensuring the stability of the climbing vehicle and ensuring the convenience of carrying after storage.
