Description
Technical Field
The invention relates to bridge detection and maintenance construction equipment, in particular to a hanger-hinged bridge maintenance vehicle capable of avoiding lamp posts, and belongs to the technical field of bridge structure maintenance engineering.
Background
With the rapid development of the construction of the traffic infrastructure in China, the number and the day-to-day increase of bridges, and the detection and maintenance work of bridges is increased year by year, so that a large number of bridge inspection vehicles or special maintenance devices are needed. In a common bridge inspection vehicle, a working platform is stretched to the bottom surface of a bridge by unfolding a movable arm on a vehicle chassis, so that an operation platform is provided for the bottom surface of the bridge. The vehicles have large volume, and need to occupy a bridge deck lane during working, thereby influencing traffic; and most of the detection vehicles are only suitable for beam bridges, when the side face of the bridge is provided with the stay cable, the stay cable blocks the stay cable, and the maneuvering arm of the detection vehicle is not easy to extend the working platform to the bottom face of the bridge. To the guy bridge or the large-scale bridge that the car can't be used is examined to the bridge, and the construction department requires to set up mobilizable steel construction work platform specially in the bridge bottom, and this kind of platform cost is not trivial, arranges in outdoors, has also had the potential safety hazard in self for a long time.
The applicant provides a patent application with the patent application number of 201210112527.4 and the invention name of 'a hanger hinged bridge maintenance vehicle' to the national intellectual property office in 2012, 4 and 17. The hanger hinged bridge maintenance vehicle in the patent application consists of a chassis with 4 wheels and a C-shaped hanger which can extend to the outer side of a bridge, wherein the C-shaped hanger consists of an upper cross beam, a vertical rod and a lower cross beam, one end of the upper cross beam is fixedly connected with the upper end of the vertical rod, one end of the lower cross beam is fixedly connected with the lower end of the vertical rod, and the other end of the upper cross beam is directly hinged with the chassis of the maintenance vehicle; or the other end of the upper cross beam is fixedly connected with a section of downward short column, and the lower end of the short column is hinged with a chassis of the maintenance vehicle. The other end of the lower cross beam provides a lifting point for the working platform below the bridge. The maintenance vehicle is light and handy to manufacture, the two maintenance vehicles are in a group and are respectively arranged on sidewalks on two sides of a bridge to walk, the maintenance vehicle does not occupy lanes, the influence on bridge floor traffic is small, and the maintenance vehicle can be disassembled and returned to a warehouse after being used up.
In order to apply the detection vehicle to the guyed bridge with obstacles on two sides of the bridge floor, the applicant also provides a patent application with the patent application number of 201210257144.6 and the invention name of 'a hanger hinged bridge maintenance vehicle capable of avoiding side obstacles' to the national intellectual property office in 7, 24 and 2012, and the maintenance vehicle carries out the following transformation on a C-shaped hanger of the maintenance vehicle: an upper cross beam is removed, a longitudinal beam is additionally arranged at each of the two ends of the upper cross beam, one longitudinal beam is fixedly connected with the upper end of a vertical rod, and the other longitudinal beam is hinged with a chassis of the maintenance vehicle or fixedly connected with the upper end of a short column; a plurality of movable cross beams which are arranged in parallel at intervals front and back are erected between the two newly added longitudinal beams, and the two newly added longitudinal beams are connected by adopting a plurality of cross beams; the movable cross beams can adopt a telescopic structure, and the fixed end of each movable cross beam is fixedly connected with one newly added longitudinal beam, so that the telescopic end is connected with a corresponding transverse socket hole arranged on the other newly added longitudinal beam. When the movable cross beam corresponding to the bridge maintenance vehicle in the advancing process is blocked by the guy cable or the lamp post on the side face of the bridge, the telescopic end of the blocked cross beam can be pulled out from the transverse socket hole, the telescopic section of the telescopic end retracts to avoid the barrier, the maintenance vehicle walks to enable the cross beam to cross the barrier, the telescopic end stretches out and reinserts into the socket hole, all cross beams are opened and closed alternately to avoid the guy cables or the lamp posts on two sides of the bridge floor, and after a certain cross beam is disconnected, other cross beams are guaranteed to be connected into a whole with the C-shaped hanging bracket. Through the sample car test, the inspection car walks on the sidewalks on the two sides of the bridge, and the stay cables and the lamp posts on the two sides of the cable-stayed bridge can be avoided through alternate opening and closing of the cross beams.
However, the following problems are also found in the improved maintenance vehicle in engineering practice: 1. in order to cross a stay cable of a cable-stayed bridge, the movable cross beams on the C-shaped hanging bracket need to be spaced at a sufficient distance, at least 3 cross beams are arranged to ensure normal operation, and two corresponding newly-added longitudinal beams are longer; when the distance between sidewalks at two sides of the bridge and the edge of the outer side of the bridge floor is more than 2m, the movable cross beam is also longer. As a result, the C-shaped hanging bracket of the maintenance vehicle is large and unwieldy, a large-tonnage crane is needed during field installation of the maintenance vehicle, two lanes are occupied, the hoisting difficulty is high, the time consumption is large, and the bridge floor traffic is greatly influenced by maintenance vehicle installation. 2. The C-shaped hanger of the maintenance vehicle is heavy, the hanger and the working platform suspended under the hanger form a heavy-end and light-foot system, and the working platform has large shaking amplitude when the maintenance vehicle runs, so that the normal operation of workers is influenced. 3. If the movable cross beam of the C-shaped hanging bracket adopts a telescopic structure, when the telescopic end of the cross beam is pulled out from the corresponding transverse hole to be separated, the internal force released at the moment of the disconnection of the cross beam is found to enable the hanging bracket and the platform to generate larger vertical vibration.
