[0022] The following is combined with Figure 1-3 The specific implementation modes of the present utility model are further described in detail.
[0023] Depend on Figure 1-3The utility model provides an aviation automatic escalator passenger elevator vehicle driving device, comprising a base 1, which is used to be fixedly connected to a vehicle body 2;
[0024] An upper seat 3, used for fixed connection with an escalator 4;
[0025] The oil cylinder 5 has one end rotatably connected to one end of the base 1 near the rear of the vehicle, and the other end rotatably connected to one end of the upper seat 3 near the rear of the vehicle. The escalator 4 can be driven to rise and fall by the extension and retraction of the oil cylinder 5.
[0026] A support rod 6, one end of which is rotatably connected to an end of the upper seat 3 close to the front of the vehicle, and the other end of which is in sliding contact with the base 1;
[0027] The protrusion 7 is arranged on the base 1 and along the length direction of the vehicle body 2. When the oil cylinder 5 is extended, the lower end of the support rod 6 slides from right to left and passes through the protrusion 7 in sequence.
[0028] The following is an explanation of the use of the above structure. When the oil cylinder 5 is extended, it drives the rear end of the escalator 4 and the vehicle body 2 to rotate, thereby raising the upper platform of the escalator 4 to facilitate the docking of the upper platform and the hatch. During the rotation of the escalator 4, the upper end of the support rod 6 is lifted, so that the lower end of the support rod 6 slides to the left and passes through the protrusion 7 in turn. In this way, the protrusion 7 has a limiting effect on the support rod 6, which can play a protective support role when the oil cylinder 5 breaks.
[0029] In order to further enhance the auxiliary effect of the support rod 6, a sliding rod 61 is slidably provided at the lower end of the support rod 6, and a clamping spring 62 is connected between the sliding rod 61 and the support rod 6. Through the setting of the clamping spring 62, when the lower end of the sliding rod 61 is stuck on the left side of a certain protrusion 7, the sliding rod 61 will be tightly in contact with the protrusion 7 to generate a supporting force, thereby sharing part of the supporting force of the cylinder 5.
[0030] In order to facilitate the smooth resetting of the support rod 6 when the escalator 4 descends, a cavity is provided inside the base 1, and a sliding opening 11 connected to the cavity is penetrated on the base 1, the protrusion 7 is slidably connected to the sliding opening 11, and a protrusion driving mechanism is provided in the cavity. When the escalator 4 descends, the protrusion driving mechanism causes the protrusion 7 to descend so that the top of the protrusion 7 just reaches the position of the surface of the base 1. In this way, the position of the protrusion 7 is a smooth plane structure, and the lower end of the support rod 6 can automatically slide to the right and reset when the escalator 4 descends.
[0031] In some embodiments, the bump driving mechanism includes an electric telescopic rod 8 , the lower end of the electric telescopic rod 8 is fixedly connected to the lower end of the cavity, and the upper end of the electric telescopic rod 8 is fixedly connected to the bump 7 .
[0032] In some embodiments, the number of the protrusions 7 is at least two, and a connecting plate 71 is fixed to the lower end of the protrusion 7 , and the upper end of the electric telescopic rod 8 is fixedly connected to the connecting plate 71 .
[0033] In this embodiment, there are two support rods 6 , and the two support rods 6 are symmetrically arranged on both sides of the lower surface of the upper seat 3 .
[0034] A first connecting rod 63 is fixed between the two supporting rods 6 , and a second connecting rod 64 is fixed to the side of the sliding rod 61 .
[0035] The base 1 and the upper base 3 can be connected to the vehicle body 2 and the escalator 4 by bolts or welding.
[0036] 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.
