Description

Technical Field

[0001] The utility model relates to the technical field of plant construction, in particular to a device for measuring the verticality and lateral bending of a large-span steel beam. Background Art

[0002] Steel beams are generally used for crane beams and working platform beams in factories, floor beams in multi-story buildings, purlins in roof structures, etc. Under the action of various stresses, steel beams will bend. Once the degree of bending reaches the limit state of the steel beam's bending resistance, the steel beam is prone to damage. Once an accident occurs, it will cause great losses.

[0003] The existing factory inspection of steel beams generally adopts the method of comparison through medium scale. The results obtained by this method are of limited accuracy and cannot accurately understand the bending condition of the steel beam. Therefore, it is necessary to design a device that can detect the bending point of the steel beam, which is convenient for measuring the bending point of the steel beam and facilitating the timely maintenance of the steel beam to prevent accidents such as fracture when the bending degree reaches the limit state.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] In one embodiment:

[0025] The top of the measuring frame 13 is provided with a movable photosensitive bracket 14 and a fixed photosensitive bracket 15, respectively.

The detection position can be adjusted as the lifting equipment or mobile equipment moves. The measuring frame 13 is arranged on the supporting structure in the equipment frame 11, and the measuring frame 13 is respectively installed with a movable photosensitive bracket 14 and a fixed photosensitive bracket 15, and the movable photosensitive bracket 14 and the fixed photosensitive bracket 15 form two detection arms, and the tops of the movable photosensitive bracket 14 and the fixed photosensitive bracket 15 are respectively installed with a movable photosensitive end 18 and a fixed photosensitive end 16, and the movable photosensitive end 18 and the fixed photosensitive end 16 respectively form two detection points; wherein the fixed photosensitive bracket 15 is fixedly installed, and the movable photosensitive bracket 14 is movably installed, and the adjusting mechanism 17 is used as an adjusting mechanism to drive the movable photosensitive bracket 14 to swing relative to the measuring frame 13; thereby, a fixed photosensitive detection surface is formed with the fixed photosensitive end 16, and the adjusting mechanism 17 is adjusted to the corresponding detection area to form another photosensitive detection surface, and the detection angle between the other photosensitive detection surfaces is used to judge the verticality and lateral bending of the large-span steel beam. In this way, we can understand the bending condition of the steel beam, facilitate the measurement of the bending point of the steel beam, and facilitate timely maintenance of the steel beam to prevent its bending degree from reaching the limit and causing accidents such as breakage.
