Problems solved by technology

However, this type of equipment in the prior art mostly adjusts the loading platform to a certain angle through the mechanical clamping device before going up and down the slope or upstairs, and uses auxiliary supports to adjust; or by setting several fixed gears, through It is always difficult to adjust the angle according to the actual slope after the gear is selected, and it is impossible to maintain the dynamic adjustment of the loading platform

Embodiment 1

[0038] Such as figure 1 As shown, it is an embodiment of a platform type crawler stair climbing vehicle applied in a stair climbing chair, including a loading platform 7, a push rod 11, and a crawler chassis 15, and the rear end of the platform and the rear end of the crawler chassis are passed through bearings or The rotating casing mechanism 18 is connected, preferably, the two ends of the hydraulic push rod 11 are respectively connected with the lugs on the reinforcing ribs at the bottom of the platform and the lifting lugs on the reinforcing pipe in the middle of the crawler chassis 15; the push rod 11 is an electro-hydraulic push rod, Since the stroke of the piston rod of the electro-hydraulic push rod is continuous, and the expansion and contraction of the piston rod is very stable, no impact force will be generated. When the wheelchair is loaded, the elderly or disabled persons on the wheelchair are more comfortable; the push rod 11 One end is connected to the middle pa...

Embodiment 2

[0049] Such as Figure 4 As shown, it is a specific embodiment of the automatic leveling method when the platform type crawler stair climbing vehicle of the present invention is applied to climbing a building, and the specific automatic leveling includes the following steps:

[0050] Step S101, start the automatic leveling system;

[0051] Step S102, judge whether the platform is in the horizontal position through the high-precision tilt switch, and when the judgment result is not in the horizontal position, the central processing module judges the tilt state of the loading platform according to the data obtained by the three-axis accelerator;

[0052] Step S103, the central processing module automatically controls the movement of the hydraulic push rod according to the tilt state of the platform, so as to adjust the platform to always be in a horizontal position.

[0053] Specifically, the step S103 judges whether the current platform is higher than the horizontal position o...

Abstract

The invention discloses an automatic leveling system of a load platform of a platform-type crawler climbing vehicle, comprising a load platform and a chassis, wherein one side of the load platform isrotatably connected with one side of the chassis; The automatic leveling system also comprises a driving device and a control device. A drive device is arranged between the load platform and the chassis to drive the load platform to rotate so as to form an included angle between the load platform and the chassis; The control device includes an inclination detection module for detecting an inclination angle between the load platform and the horizontal plane. The control device controls the driving device to drive the platform to rotate according to the inclination angle so as to make the inclination angle approach to zero degree so as to change the included angle, thereby controlling the platform to keep the horizontal state. The control device controls the driving device to rotate according to the inclination angle so as to make the inclination angle approach to zero degree so as to change the included angle. In the process of climbing or downhill, the platform can make real-time adjustments, to a certain extent, the platform has always maintained a horizontal state, the whole process uses closed-loop control, real-time monitoring and adjustment of the position of the platform.

Description

technical field [0001] The invention relates to the field of a platform-type crawler stair climbing vehicle, in particular to a crawler stair climbing vehicle equipped with a loading platform, an automatic leveling system and an automatic leveling method. Background technique [0002] Stair climbing equipment can be roughly divided into the following two categories according to their different functions: the first type is mainly used for stair climbing wheelchairs for assisting disabled people to go up and down stairs; the second type is mainly used for stair climbing and carrying goods in the stairwell car. At present, the stair-climbing equipment at home and abroad can be mainly divided into the following three types according to the stair-climbing method: star wheel type, foot type and crawler type. [0003] Star-wheel type: The most common electric stair climbing vehicle on the market uses wheel sets, mainly including three-wheel sets, four-wheel sets, five-wheel sets a...
