Overturning detection device for overhead working truck

Abstract

The invention provides an overturning detection device for an overhead working truck. The overturning detection device at least comprises a detection switch and one or more region detecting plates, wherein the detection switch is fixed on a rotating part of a slewing mechanism of the overhead working truck; the region detecting plates are fixed on a fixed part of the slewing mechanism of the overhead working truck; the contact end of the detection switch cooperates with the region detecting plates; when the detection switch is in contact with the region detecting plates, the region detection switch is switched on, so that the detection switch rotates to the detection region; and when the region detection switch is separated from the region detecting plates, the region detection switch is switched off, so that the detection switch rotates to the non-detection region, and then the detection of the slewing region is realized. The overturning detection device disclosed by the invention hasthe beneficial effects that according to different region detecting requirements, various region detecting requirements can be realized through mounting the region detecting plates of different angles and different numbers; the mounting is simple, stable and reliable; the cost is low; and repair is convenient.

Description

technical field [0001] The invention relates to a rotation detection device of an aerial work vehicle. Background technique [0002] Aerial work vehicle refers to a special vehicle for transporting staff and equipment to the site and performing aerial work. The boom of the aerial work vehicle and the frame are connected and fixed by a slewing mechanism, and the boom can be relative to the frame under the action of the slewing mechanism. Rotation occurs, and the slewing mechanism needs to detect the slewing area when it is rotating; there are two existing detection methods for the slewing area, one is to install a central collector ring on the central slewing body, and then install half rings with different angles to detect different The area detection; its shortcoming is: the area detection that adorns half ring realizes: the stability of the first central torrent ring is not too high. Second, if it is a multi-area detection, it is necessary to install multiple half-rings, ...

[0002] Aerial work vehicle refers to a special vehicle that transports staff and equipment to the site and performs aerial work. The boom and frame of the aerial work vehicle are connected and fixed by a slewing mechanism, and the boom can be relative to the frame under the action of the slewing mechanism. Rotation occurs, and the slewing mechanism needs to detect the slewing area when it is rotating; there are two existing detection methods for the slewing area, one is to install a central collector ring on the central slewing body, and then install half rings with different angles to detect different The area detection; its disadvantages are: the area detection realized by installing a half ring: the stability of the first center torrent ring is not too high

Second, if it is a multi-area detection, it is necessary to install multiple half-rings, so that the number of layers of the central collector ring will increase, which will increase the instability.

Third, it is not easy to replace if it breaks down

Another method is to install an encoder on the central rotary body to realize the detection of the rotary area; its disadvantages are: to install an encoder to realize the detection of the rotary area: the first pair of installations requires high precision, the second is high cost, and the third is inconvenient to replace
