Description

TECHNICAL FIELD

[0001] The utility model belongs to the escalator transport tool field, concretely relates to an escalator transport vehicle. BACKGROUND

[0002] In the field of escalator manufacturing and installation, the rigid structure characteristics of the escalator truss due to its fixed inclination angle (usually 30° or 35°) bring special technical problems when the escalator is transported after being disassembled as a whole. The traditional horizontal cargo platform cannot directly adapt to such special-shaped components, and forcibly flattening will lead to two major technical risks: first, the sudden change in stress distribution of the truss may cause plastic deformation of the metal structure, resulting in the deviation of the guide rail positioning reference; second, the imbalance of the pre-tightening force of the step chain wheel set will increase the complexity of the driving system debugging, directly affecting the efficiency of on-site installation.

[0003] The existing transportation scheme mostly uses simple inclined support combined with ordinary flatbed trucks, which has the following significant defects: the fixed angle of the support cannot adapt to the slope tolerance range (±0.5°) of different models of escalators, resulting in local stress concentration on the contact surface.

[0004] Therefore, there is an urgent need to develop special transportation equipment with slope self-adaptation. SUMMARY

[0005] An object of the utility model is to solve at least the above problems and provide at least the advantages to be explained later.

[0006] The utility model provides the following technical scheme: an escalator transport vehicle, comprising a vehicle body, support units are distributed on the vehicle body along the length direction of the escalator, the support units comprise a swing part and a lifting part, the lifting part carries the swing part, the swing axis of the swing part is perpendicular to the length direction of the escalator, the lifting part changes the height of the swing part, and the swing part swings to adapt to the slope of the bottom of the escalator.

[0007] Further, the lifting part of the support unit comprises a scissor lifting platform, two connecting ears are arranged on the top plate of the scissor lifting platform, the swing part comprises a support plate, and the rotating shaft at the bottom surface of the support plate penetrates the two connecting ears.

[0008] Further, the vehicle body comprises a vehicle plate, the support units are installed on the vehicle plate, and walking wheels are arranged at the bottom of the vehicle plate.

[0009] Further, the walking wheels at the bottom of the vehicle plate are divided into steering walking wheels and straight walking wheels, the steering walking wheels are located at both ends, and the straight walking wheels are distributed between the steering walking wheels.

[0010] Further, longitudinal beams are arranged at the bottom surface of the vehicle plate, and cross beams are connected between the longitudinal beams.

[0011] Further, trailer hooks are installed at the front and rear of the vehicle plate, and the trailer hooks are connected with the longitudinal beams.

[0012] Furthermore, the steering wheel includes a rotary seat, a fixed seat, and a drive motor; the fixed seat is fixed to the vehicle plate, the rotary seat is connected to the fixed seat, the rotary seat is connected to the wheel, the rotary seat is provided with a gear ring coaxial with the rotating shaft, the drive motor is mounted on the fixed seat, and the gear on the drive motor meshes with the gear ring.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] This utility model provides an escalator transport vehicle that achieves height adjustment in the vertical direction (Z-axis) and posture compensation in the horizontal direction (XY plane) through the coordinated action of a "lifting + swinging" dual-degree-of-freedom motion mechanism. A specially designed swinging axis (perpendicular to the length of the escalator) can sense changes in the slope of the escalator bottom in real time, causing the support plate to swing with the slope of the escalator bottom. This solves the technical problems of poor slope adaptability, insufficient stability, and low loading and unloading efficiency of traditional escalator transport vehicles, making it particularly suitable for continuous cargo transportation scenarios in densely populated places such as airports, subways, and shopping malls.
