Problems solved by technology

The existing cabin leveling mechanism generally uses a hydraulic cylinder for leveling, which has the following disadvantages: 1. It needs a hydraulic power source (hydraulic pump station), 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 (circular arc segment 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 leakage of the car body is prone to instability when the station is stopped for a long time

Embodiment 1

[0039] Embodiment 1, Such as figure 1 , Figure 5 As shown, when the slope changes at an inclination angle of 0 to 45°, 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 running 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.

Embodiment 2

[0042] Embodiment 2, Such 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 levelling device and method for a slope-variable inclined operation container is applied to car bodies of inclined operation containers or mancars which are changed in slope or change track to operate due to influences of building shapes or working conditions of roadways. The device comprises a car body, a movable bottom plate, an automatic levelling assembly and a pulley or a backpack bearing frame; the automatic levelling of the slope-variable inclined operation container is realized by changing the angle of a lifting platform on the pulley or the backpack bearing frame under various working conditions; when the inclined operation container operates at a slope-variable guide rail section, and a position posture sensor monitors that the angle of the car body is changed, a signal is transmitted to an automatic levelling control system, and the control system controls a servo motor to move after analyzing the signal; and the automatic levelling assembly compensates the angle change of the car body to enable the car body to be in a horizontal posture all the time, thereby realizing the operation of the inclined operation container on the slope-variable tracks. The automatic levelling device is simple in structure, safe, reliable, small in occupied space, good in levelling performance and wide in application range and can realize real-time fine adjustment.

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...
