Hoisting machinery structure deformation detection device

Abstract

The invention discloses a hoisting machinery structure deformation detection device. The hoisting machinery structure deformation detection device comprises a crane and a detection trolley, wherein the detection trolley is mounted at the top of the crane; a transverse beam is arranged at the top of the crane; detection grooves are formed in two sides of the transverse beam; a movable groove is longitudinally formed in the middle of the top surface of the transverse beam; the detection trolley comprises a trolley body, detection rods and a walking mechanism; the two detection rods are arrangedand are arranged at two sides of the trolley body correspondingly; each detection rod is of an inverted U-shaped structure; and one end of each detection rod extends into the trolley body and the other end of each detection rod extends into the corresponding detection groove. According to the hoisting machinery structure deformation detection device, the detection trolley can move back and forth on the crane; in a movement process, the lower ends of the detection rods are stuck on the surface of the transverse beam to detect the transverse beam; when the transverse beam is deformed, the detection rods are influenced to a certain extent and generate displacement; an infrared receiver does not receive an infrared signal and the transverse beam is deformed; an infrared distance measurement mechanism is matched to detect the distance between the two detection rods and a detection result is relatively accurate.

Description

technical field [0001] The invention relates to the technical field of deformation detection of hoisting machinery structures, and more specifically relates to a detection device for deformation of hoisting machinery structures. Background technique [0002] Hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal moving of heavy objects. Its scope is defined as lifts with a rated lifting capacity greater than or equal to 0.5t; A crane equal to 2m and an electric hoist with a fixed load-bearing form, etc. [0003] Lifting is an industrial process of transporting machinery or other objects from one place to another. Most hoisting machines start vertical or vertical and horizontal working strokes after picking up materials from the spreader, unload after reaching the destination, and then empty travel to the picking place to complete a working cycle, and then carry out the second lifting. Generally speaking, when t...

Problems solved by technology

[0004] In the prior art, the infrared transmitter is fixed on the lifting machinery to detect it, the accuracy of the detection result is poor, the receiver and the transmitter are exposed in the air, and the dust in the hoisting work area is easy to adhere to the receiver and the transmitter. on the transmitter, causing detection failure and affecting its normal use
