Device for detecting lifting appliance

Abstract

The invention discloses a device for detecting a lifting appliance, and the device is provided with a detector switch protecting plate which is provided with a waist-shaped hole, wherein the length direction of the waist-shaped hole is consistent with the movement direction of a suspension arm of the lifting appliance; the detector switch protecting plate is connected to a switch bracket by virtue of a fastening bolt provided with a fixing sleeve; a detector switch is arranged at the waist-shaped hole; and the bottom of the detector switch is higher than that of the detector switch protecting plate. The self-protection capability is improved, and the aim of automatic detection can be achieved; and the device is convenient to maintain and low in failure rate, thus the equipment performance can be improved. After the technical scheme is adopted, the lifting appliance is prevented from approaching to the detector switch, and the interference is prevented from being caused, so that the detector switch is prevented from being damaged, and the normal detection of the detector switch is guaranteed. The detector switch can move according to the height accuracy error of the suspension arm of the lifting appliance, so that the aims of automatic adjustment and detection can be achieved. The self-protection capability of the switch is improved, and the aim of automatic detection can be achieved; and the device is convenient to maintain and low in failure rate, so that the equipment performance can be improved.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing process equipment, and relates to the technology of hoisting and transporting equipment for products on an automobile production line. More specifically, the invention relates to a detection device for a spreader. Background technique [0002] At present, in automobile production, especially in the transportation and storage of car bodies between the welding shop and the painting shop, considering the cost performance of the equipment, many production lines use push rod suspension conveyor chains. When carrying out vertical hanging, the boom of the spreader must be opened and closed, and the positioning detection of the boom closing or opening is realized by the proximity switch detection. [0003] Existing technologies such as figure 1 Shown: [0004] The body needs to be transported from welding to painting by mechanized transportation methods such as catenary. The body is loa...
