Problems solved by technology

Existing car body leveling mechanisms generally use hydraulic cylinders for leveling, which have the following disadvantages: 1. A hydraulic power source (hydraulic pump station) is required, which takes up a lot of space and is heavy; 2. The hydraulic system has hysteresis, and the real-time leveling effect is not good ;3. The continuous micro-adjustment of the hydraulic cylinder (arc section operation) has poor transformation effect, and the control of small flow changes is difficult to realize; 4. The system has high requirements for the pressure of the hydraulic cylinder, and the leaking compartment is prone to instability when the station is stopped for a long time

Embodiment 1

[0039] Embodiment 1, as figure 1 , Figure 5 As shown, when the slope varies from 0 to 45° to run the container obliquely, the pulley 4 is used, and the angle of the lifting platform 4-1 on the pulley 4 is changed to adapt to the variable-slope obliquely run container under various working conditions. The movable floor 2 at the bottom of the car body 1 is provided with a pose sensor 1-1 for real-time monitoring of the pose change of the car body, an automatic leveling assembly 3 is hinged under the movable floor 2, and a pulley 4 is arranged below the automatic leveling assembly 3, The trolley 4 is composed of a lifting platform 4-1 and a guide wheel 4-2. The left end of the automatic leveling assembly 3 and the lifting platform 4-1 is hinged through two hinged pillars, and the two hinged pillars at the right end of the movable floor 2 are connected to the lifting platform 4. The right end of -1 is hinged.

[0040] Such as Figure 6 - Figure 14 As shown, the automatic lev...

Embodiment 2

[0042] Embodiment 2, as figure 2 , image 3 , Figure 4 As shown, when the slope changes obliquely to the operating container at a large inclination angle of 45-90°, the backpack-type carrier 5 is adopted, and the angle of the lifting platform 4-1 on the backpack-type carrier 5 is changed to adapt to changes in various working conditions. The slope runs the container obliquely. Its structure is basically the same as that of Embodiment 1, and the similarities are omitted. The difference is that the backpack-type carrier 5 includes a lifting platform 4-1 and a guide shoe 4-3 arranged at the bottom of the lifting platform 4-1, and the automatic leveling assembly 3 is connected to the left end of the lifting platform 4-1. Hinged, the right end of the movable bottom plate 2 is provided with two hinged pillars and the right end of the lifting platform 4-1 is hinged.

Abstract

An automatic leveling device and method for a variable-slope inclined running container, which is suitable for the inclined running container body or man-vehicle whose slope changes or changes the trajectory due to the influence of the shape of the building or the working condition of the roadway. The device includes a box body, a movable floor, an automatic leveling assembly, and a trolley or a knapsack-type carrier. By changing the angle of the lifting platform on the trolley or knapsack-type carrier, it can adapt to the automatic adjustment of the variable-slope oblique running container under various working conditions. Leveling, when the inclined running container runs on the guide rail section with variable slope, the position and attitude sensor detects the angle change of the car body, and transmits the signal to the automatic leveling control system. The control system controls the movement of the servo motor after analyzing the signal, and automatically adjusts The action of the flat component compensates the angle change of the car body, so that the car body is always in a horizontal posture, and realizes the operation of the obliquely running container on the variable-slope track. The utility model has the advantages of simple structure, safety and reliability, small space occupation, good leveling performance, real-time micro-adjustment, and wide application range.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an automatic leveling device and method for a variable-slope oblique operation container, especially suitable for oblique operation containers affected by mine roadway conditions or building shapes that change the slope or change the trajectory . Background technique [0002] With the continuous emergence of modern high-rise buildings, the importance and superiority of elevators as a convenient and fast vertical transportation tool are increasingly reflected. With the rapid development of elevator technology, the emergence of special elevators used in different environments and places facilitates people's lives. In order to provide convenience for mine roadways, sightseeing spots, buildings located on hillsides and hilltops, areas where residential buildings are built on hillsides due to urban area constraints, complex underground roadways, and transportation for maintenance personnel a...
