In the process, the ladder body, the mounting plate, the telescopic rods, the moving wheels and other parts can form a light frame, carrying and transportation are facilitated, and therefore the light weight aim is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of escalators, in particular to a lightweight aviation escalator. Background Art

[0002] The aviation passenger staircase not only includes the escalator, but also the vehicle responsible for moving the escalator from the ground to the designated position of the aircraft. This design ensures that the escalator can quickly and stably transport passengers from the ground to the aircraft when needed, saving passengers' physical strength and improving the operating efficiency of airlines.

[0003] However, current escalators are usually fixed installations, which are bulky and difficult to maintain. This brings great difficulties to the use and maintenance of escalators. For example, when an escalator fails, it must be completely disassembled and sent to a maintenance point for repair, which is not only time-consuming and labor-intensive, but also affects the normal operation of the airline passenger elevator. Therefore, it is necessary to improve the existing installation method of escalators to make them easier to maintain and use. Utility Model Content

Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings:

[0021] Figure 2 This is a schematic diagram of the installation structure of the installation plate of the utility model. DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-2 The specific implementation modes of the present utility model are further described in detail.

[0023] Depend on Figure 1-2The utility model provides a lightweight aviation escalator, comprising a ladder body 1, a mounting plate 3 arranged at the bottom of the ladder body 1 for fixing with a vehicle body 2, and a driving device 4 arranged between the ladder body 1 and the mounting plate 3 for driving the ladder body 1 to be raised or lowered. The ladder body 1 is connected to the vehicle body 2 through the mounting plate 3 to form a vehicle that can drive the escalator itself to move. The vehicle can easily disassemble the ladder body 1 from the vehicle body 2 to achieve a lightweight design of the product.

[0024] In addition, side plates 5 are slidably provided on both sides of the mounting plate 3, and a telescopic rod 6 is vertically slidably provided at the lower end of the side plate 5. A moving wheel 7 is installed at the lower end of the telescopic rod 6, and a fixing mechanism 8 for fixing to the vehicle body 2 is provided on the telescopic rod 6. The side plates 5 are arranged on both sides of the vehicle body 2, which can limit the movement of the mounting plate 3 in the lateral direction of the vehicle body 2. During normal use, the telescopic rod 6 is in a retracted state and is locked by the fixing mechanism 8. When disassembling the ladder body 1, the mounting plate 3 is separated from the vehicle body 1, and the mounting plate 3, the side plates 5, the telescopic rod 6 and the moving wheels 7 can constitute a movable frame of the ladder body 1, thereby facilitating the movement of the ladder body 1, and since it is separated from the vehicle body 1, the volume and weight are greatly reduced, which is convenient for transportation.

[0025] Slide grooves are provided on both sides of the mounting plate 3, the upper ends of the side plates 5 are slidably connected to the slide grooves, and a driving mechanism 9 for driving the side plates 5 to slide is provided in the slide grooves.

[0026] The driving mechanism 9 comprises:

[0027] The bidirectional threaded screw 91 is rotatably mounted in the mounting plate 3, and its two ends are respectively threadedly connected to the side plates 5 on both sides of the mounting plate 3;

[0028] The driven gear 92 is fixedly connected to the bidirectional threaded screw 91;

[0029] The driving gear 93 is meshed and connected with the driven gear 92 , and the driving gear 93 is connected with a motor 94 , and the motor 94 is fixedly connected with the mounting plate 3 .

[0030] The working condition of the driving mechanism 9 is described below. When working, the external power supply of the motor 94 is turned on, the motor 94 drives the driving gear 93 to rotate, the driving gear 93 drives the driven gear 92 to rotate, the driven gear 92 drives the bidirectional threaded screw 91 to rotate, and the bidirectional threaded screw 91 drives the side panels 5 on both sides of the mounting plate 3 to move closer to or away from each other. In this way, when the mounting plate 3 is connected to the vehicle body 1, the side panels 5 can be opened outward to form a larger contact surface with the ground, thereby increasing stability. During installation, the ladder body 1 can be pushed into the vehicle body 2 from the rear, and then the distance between the side panels 5 can be reduced and clamped on both sides of the vehicle body 2.

[0031] Please refer to Figure 2, a specific embodiment of the fixing mechanism 8 is as follows, comprising:

[0032] The electric telescopic rod 81 is fixedly connected to the side plate 5, and the telescopic end of the electric telescopic rod 81 is fixedly connected to the telescopic rod 6. When the ladder body 1 is installed on the vehicle body 2, the electric telescopic rod 81 contracts to move the telescopic rod 6 upward, so that the moving wheel 7 is separated from the ground;

[0033] The fixing groove 82 is embedded in the lower surface of the vehicle body 2 and corresponds to the upper end position of the telescopic rod 6. When the telescopic rod 6 moves upward, it is inserted into the fixing groove 82, thereby limiting the movement of the mounting plate 3 in the horizontal direction;

[0034] In order to further limit the movement of the mounting plate 3 in the vertical direction of the vehicle body 2, a pressure plate 61 is fixed to the upper end of the telescopic rod 6. The diameter of the pressure plate 61 is larger than the diameter of the fixing groove 82. When the telescopic rod 6 moves upward, it drives the pressure plate 61 to press against the lower surface of the vehicle body 2, thereby fixing the mounting plate 3 in the vertical direction.

[0035] The number of the side plates 5 is four.

[0036] The moving wheel 7 is a universal wheel structure.

[0037] Working principle: The utility model is a lightweight aviation escalator. When the ladder body 1 needs to be disassembled, the electric telescopic rod 81 is extended to drive the telescopic rod 6 to move downward. When the telescopic rod 6 moves downward, its upper end is separated from the fixed groove 82, and when the telescopic rod 6 moves downward, the moving wheel 7 contacts the ground, and then the driving mechanism 9 works to drive the side panels 5 on both sides of the mounting plate 3 to move outward, so that the side panels 5 are separated from the two sides of the vehicle body 2, and then the vehicle body 2 is opened forward to separate the mounting plate 3 from the vehicle body 1. In this way, the mounting plate 3, the side panels 5, the telescopic rod 6 and the moving wheels 7 can constitute a movable frame of the ladder body 1, so as to facilitate the movement of the ladder body 1, and because it is separated from the vehicle body 1, the volume and weight are greatly reduced, which is convenient for transportation, so as to realize the lightweight design of the product.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
