Problems solved by technology

Although the bridge deck walking detection mechanism is convenient to use, due to the way of walking on the bridge deck (on the railroad track) or erecting a bridge on a ship to detect the bridge, it is bound to close the traffic on the road surface, the through hole of the bridge or the navigation hole, which has a great impact on traffic. Large, but also has certain limitations in safety performance
Although the existing suspension-type walking inspection vehicles under bridges do not affect traffic, they generally have a small detection range and can only detect bridge bottom plates, webs, flanges and other parts within a single span. For super-large bridges such as cross-sea bridges For example, if one inspection vehicle is arranged in each span, hundreds of inspection vehicles will be required, which will greatly increase the cost of the bridge

Embodiment 1

[0034] In the rotary lifting maintenance platform of the present invention, gantry frames 9 are respectively arranged at both ends of the truss system, a drive mechanism is arranged on the gantry frames 9, and a maintenance platform 1 is hinged on the gantry frames 9 (according to actual needs, the The maintenance platform 1 is hinged to both ends of the truss system), the maintenance platform 1 can swing relative to the hinge point, and a swing driving device 3 is connected between the maintenance platform 1 and the truss system, and the two ends of the swing driving device 3 are respectively hinged on On the inspection platform 1 and the truss system, the inspection platform 1 is controlled to swing relative to the hinge point. Wherein the swing driving device 3 can adopt such as figure 1 For the hydraulic expansion device shown in , when the hydraulic expansion device expands and contracts, the maintenance platform 1 can swing relative to the hinge point, so when it is nece...

Embodiment 2

[0036] Embodiment 2 On the basis of Embodiment 1, the rotary lifting maintenance platform of the present invention, wherein the truss system includes a main truss 5 and a truss beam, the main truss 5 is fixed on the truss beam, and the faucet frames 9 at both ends of the truss system Integral inspection platforms 1 are respectively hinged on the top, that is, the two integral inspection platforms 1 are respectively hinged on the faucet frame 9 at the two ends of the main truss 5 (it can also be hinged on the main truss 5), and the two swing driving devices 3 are respectively connected On the truss beam, it is possible to control the height of the integral maintenance platform by controlling the two swing driving devices 3. The hinged point of the integral maintenance platform and the main truss 5 is used as the swing fulcrum to adjust and control the height of the integral maintenance platform arbitrarily. It is composed of two I-beams and transverse connecting rods. Two swingi...

Embodiment 3

[0046] Embodiment 3 is similar to Embodiment 1 and Embodiment 2. On the basis of Embodiment 1 and Embodiment 2, the maintenance platform 1 adopts a separate maintenance platform, which includes an upper maintenance platform 1-1 and a lower maintenance platform 1-2, The upper end of the lower maintenance platform 1-2 is hinged to the upper maintenance platform 1-1, the lower end of the lower maintenance platform 1-2 is hinged to the gantry 9, and the two ends of the swing driving device 3 are respectively connected to the truss system and the lower maintenance platform 1-2, wherein the upper maintenance platform 1-1 and the lower maintenance platform 1-2 are movably connected by a rotating pin shaft 1-3. Positioning holes are respectively arranged on the upper maintenance platform 1-1 and the lower maintenance platform 1-2. When the two positioning holes are aligned, the positioning pin shaft 1-4 is inserted in the positioning hole. At this time, the positioning pin shaft 1-4 is...

Abstract

The invention discloses a rotary lifting maintenance platform, which belongs to the technical field of the bridge inspection vehicle. The rotary lifting maintenance platform comprises a maintenance platform, wherein the maintenance platform is hinged to a truss system or a portal frame; an oscillating driving device is connected between the maintenance platform and the truss system; and the oscillating driving device can control the maintenance platform to oscillate in a manner relative to a hinge point. The rotary lifting maintenance platform disclosed by the invention has the advantages of simpleness in operation, convenience in use, high maintenance efficiency and safe and reliable performance and is suitable to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of bridge inspection vehicles, in particular to a rotatable lifting inspection platform, which can inspect and maintain the lower part of the wing plate and the inclined web of the bridge. Background technique [0002] The bridge inspection vehicle is a special equipment suitable for disease maintenance and preventive inspection of large and medium-sized bridges. The main function is to carry out a comprehensive inspection and repair of each structure of the bridge to provide guarantee for the safety of the bridge. The maintenance content includes whether the components are distorted, deformed and partially damaged, whether the rivets and bolts are loose, detached and broken, whether the nodes are slipped or cracked; Whether there are cracks or disengagement on the edge of the seam; whether the paint layer is cracked, peeled, peeled off, whether the structure is rusted, etc. The bridge inspection vehicle ca...
