Embodiment Construction

[0021] See figure 1 , which is a height detection device for a hydraulically suspended vehicle related to the present invention. It includes a fixed walking support 1, and one end of the walking support 1 is forked to form a walking support support. Hinged walking arm 4 between the walking support bearings, see figure 1 , the walking support 1 and the walking arm 4 are connected by a pin 3, and the walking arm 4 can rotate relative to the walking support 1. The walking crank arm 4 is also connected with one end of the suspension oil cylinder 5, and the other end of the suspension oil cylinder 5 is connected with the upper support surface 11 on the upper end of the walking support 1. When the suspension oil cylinder 5 will have a stroke change, the walking crank arm 4 will rotate, so it can be adjusted. The upper and lower height positions of the upper supporting surface 11. The upper support surface 11 moves up and down, which can drive the vehicle working platform to move ...

Abstract

The invention discloses a height detection device for a hydraulic suspension vehicle, which comprises a fixed traveling support and a traveling crankarm which is hinged between traveling support brackets and rotates relative to the traveling support. The height detection device also comprises detection pieces which are oppositely arranged at both sides of the traveling support brackets; each detection piece corresponds to a set of pieces to be detected arranged on the traveling crankarm; one set of pieces to be detected comprise a high-order piece to be detected, and the other set of pieces to be detected comprise a low-order piece to be detected. In the invention, the height of a working platform of the vehicle is determined through arranging a detection switch according to an obtained detection signal. The invention has a simple structure and is easy to implement; the artificial detection is not needed, multiple height positions of the working platform of the vehicle can also be detected and the relevant safe operation and positioning control are further carried out. Moreover, the use cost is reduced and the actual working requirement can be satisfied.

Description

technical field [0001] The invention belongs to the detection field, and in particular relates to a height detection device specially used for hydraulically suspended vehicles. Background technique [0002] There is a hydraulic suspension system in special vehicles such as hydraulic power flatbed vehicles. By controlling the telescopic length of the suspension cylinder, the height of the vehicle working platform can be controlled. Position (ie, middle position) and the highest position, the driver can facilitate the operation of the vehicle and at the same time realize safety restrictions. In other similar vehicles, there are generally two ways to control its height: [0003] One does not detect the height position of the vehicle working platform, but is directly controlled by the driver operating the relevant lifting handle and the length of the suspension oil cylinder itself. This makes height control more difficult, and there are no safety protection measures for suspen...
