Problems solved by technology

At present, the steel cables of cable-stayed bridges are usually detected by manual detection, which is very dangerous, and the detection efficiency is extremely low, which is not conducive to batch detection
Moreover, some existing detection equipment cannot stay accurately and stably during the detection process, and is prone to shaking, resulting in inaccurate detection results

Embodiment Construction

[0030] The present invention will be further described below in conjunction with accompanying drawing:

[0031] Such as Figure 1-Figure 3 A kind of spiral lifting equipment shown, the equipment together with the support mechanism and the detection mechanism are composed as follows: Figure 10-Figure 14 The cable-stayed bridge cable detection device shown. The device includes a fixed lock adjustment mechanism, a brake mechanism and an autorotation mechanism. The support mechanism is a frame, which is used to install and fix the other mechanisms and play a role of support and fixation. The brake mechanism is used to provide power for the fixed lock adjustment mechanism and the self-rotation mechanism to operate. The fixed lock adjustment mechanism can not only make the above detection device rise and fall along the length direction of the rope 600 under the drive of the brake mechanism, but also accurately stay at the position where the rope 600 needs to be detected, and can...

Abstract

The invention relates to spiral lifting equipment which comprises two first main wheel assemblies, two second main wheel assemblies, a first adjusting piece used for adjusting the distance between the two first main wheel assemblies, a second adjusting piece used for adjusting the distance between the two second main wheel assemblies, a first transmission assembly, a second transmission assembly, a first motor, a second motor and a steering gear ring. The first transmission assembly and the second transmission assembly each comprise a worm and a worm gear meshed with the worm. The worm wheel drives the first main wheel assembly and the second main wheel assembly to move through the first transmission unit. The device can overcome the defects in the prior art, can move and rotate in the length direction of the cable-stayed bridge steel cable, can accurately and stably stay at any position of the cable-stayed bridge steel cable, and ensures the smooth proceeding of the detection process.

Description

technical field [0001] The invention relates to the technical field of cable-stayed bridge cable detection, in particular to a spiral lifting device. Background technique [0002] Cable-stayed bridge steel cables usually use a steel cable structure to suspend the bridge deck and bridge piers. Due to long-term exposure to the natural environment, the steel cables of cable-stayed bridges will inevitably be eroded by the pollution of the natural environment. In order to ensure the safety of cable-stayed bridges and avoid damage to and endanger public safety, regular inspection Inspection and maintenance of bridges and cable-stayed bridge cables. At present, the steel cables of cable-stayed bridges are usually detected by manual detection, which is very dangerous, and the detection efficiency is extremely low, which is not conducive to batch detection. Moreover, some existing detection equipment cannot stop accurately and stably during the detection process, and is prone to sh...
