Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

Embodiment 1, an aerial working platform, as shown in fig. 1, 2 and 3, comprises a main platform 1 and an extension platform 2, wherein the extension platform 2 horizontally slides on the main platform 1, and a user stands on the extension platform 2 to realize adjustment of a horizontal standing position in the aerial working process. In this case, the main platform 1 comprises a floor 11 extending in a horizontal direction, and side elevation plates 12 are provided on the sides thereof. The side high plate 12 extends in the vertical direction and has a certain height, and the guide rail 3 is provided on the upper surface of the side high plate 12.

The roller assembly 4 is mounted on the extension platform 2 and abuts against the guide rail 3 to slide, so that the extension platform 2 slides relative to the main platform 1. Since the guide rail 3 is installed on the upper surface of the side high plate 12, it has a higher height space with respect to the bottom plate 11. Due to the existence of the height space, sundries on the bottom plate 11 are difficult to cover on the guide rail 3, obstacles are difficult to appear on the rolling line of the roller assembly 4, the phenomena of clamping wheels and the like are avoided, and the rolling smoothness of the extension platform 2 is improved.

In this embodiment, the roller assembly 4 is mounted on the side wall of the extension platform 2, instead of on the bottom surface of the extension platform 2, so that the bottom surface of the extension platform 2 may not need to be high, and may sink to be close to the floor 11, and the center of gravity moves downward, thereby improving the safety and stability during sliding.

As shown in fig. 4, the extension platform 2 is provided with a long leakage groove 21, which may be a waist-shaped groove, with round corners and a certain length, so that some small-volume sundries and accumulated water on the extension platform 2 can be smoothly discharged from the long leakage groove 21, and the cleanliness of the extension platform 2 is further improved.

As shown in fig. 5 and 7, the roller assembly 4 comprises a plurality of components, and the retainer 41 is fixedly connected to the side wall of the extension platform 2 by a connecting bolt 43, on which an axle 42 is provided. The wheel shaft 42 is sleeved with a bearing 45, the bearing 45 is sleeved with a wheel body 44, and the smoothness of the rotation of the wheel body 44 is improved. A retainer ring 46, which may be a C-ring in the prior art, is further disposed on the axle 42, and limits the axial position of the bearing 45 on the axle 42, so as to improve the stability of the wheel body 44.

The locking of the sliding position of the extension platform 2 relative to the main platform 1 is achieved by means of locking means 5. As shown in fig. 2 and 6, the locking bar 51 is connected to the main platform 1 to extend in the horizontal direction. The plurality of locking grooves 52 are arranged in the horizontal direction of the locking bar 51. When the user depresses the foot 531 with his foot, the latch 532, which is hinged thereto, is lifted off the locking slot 52, which is now free for the extension platform 2, allowing sliding. When the user leaves the pedal 531, the latch 532 falls down under the drive of its own weight or elastic force and falls into the corresponding locking groove 52, thereby locking the position of the extension platform 2 relative to the main platform 1. In this way, when the user does not operate, the extension platform 2 defaults to a locked state, and safety is further improved.

The aerial work platform truck comprises the aerial work platform and a truck body, wherein a lifting device for adjusting the height position of the aerial work platform is mounted on the truck body. The lifting device can adopt a scissor type lifter similar to a jack structure in the prior art.
