Technical field

The invention belongs to equipment for bridge construction technical fields, and in particular to a kind of bridge construction platform.

Background technique

The construction of modern bridge and mainteinance repair, construction personnel need operation platform that can easily reach construction portion It is installed and is detected in position.According to the design feature of bridge, conventional method is to set up console mode scaffold, can guarantee construction in this way The safety of operating personnel, but set up foot and build the scaffold of console mode and need long time, it will affect project progress, and And it is also cumbersome in the disassembly in later period.And this platform is only applicable to small bridge, certain across the big of mountain stream river In the maintenance of type bridge, do not have the condition for setting up console mode scaffold, then considers to apply suspension type platform construction technology.But It is to be made based on existing hanging-type construction platform needs to arrange when in use large scale equipment on bridge floor, while suspension being provided The mobile power of formula platform, thus it is larger using the breadth of the occupied bridge floor of this large scale equipment, it needs to seal bridge construction, this is just Biggish pressure is caused to traffic.

Summary of the invention

Technical problem to be solved by the present invention lies in a kind of bridge construction platform is provided, can be used not only for outstanding Hanging type platform is effectively supported, meets the construction requirement of suspension type platform, and does not need to block the traffic of bridge floor, greatly slow Solve traffic pressure.

Technical scheme is as follows: a kind of bridge construction platform, and two including being symmetrically disposed on bridge two sides A suspension type platform, along two track girders being parallel to each other of the longitudinally fixed laying of bridge floor and the dragon being slidably connected with track girder Door frame, the portal frame are made of steel truss splicing；Suspension type platform is fixedly installed with position-limited rack close to the side of portal frame, limit Position frame is equipped with downward opening limit card slot close to the side of portal frame, the steel guard rail clamping of the limit card slot and bridge and should Position-limited rack forms the structure being slidably connected by limit card slot and steel guard rail；Steel wire is equipped between portal frame and suspension type platform It restricts, is fixedly connected at the top of one end of wirerope and portal frame, is fixedly connected at the top of the other end and suspension type platform；Two outstanding It is equipped with support rod between hanging type platform, the both ends of support rod are hinged or be bolted with two suspension type platforms respectively.

Further, in order to promote portal frame to be able to bear bigger weight, while traffic accident is reduced, the dragon Door frame is up-narrow and down-wide, and limit for height board and construction indicator light are equipped on the portal frame.

Further, the connection of suspension type platform and support rod is more stable in order to prevent, more conducively wirerope plays its pulling force Effect, the both ends of the support rod are hinged with two suspension type platforms respectively.

Further, preventing driver from colliding portal frame to be further reduced the generation of construction safety accident and safety occurring Accident is hung with Crashworthy plate on the support rod.

This programme the utility model has the advantages that two suspension type platforms in the present invention were supported by portal frame.Portal frame The top of suspension type platform is lived by wire rope hanging.Two suspension type platforms under the supporting role of support rod, will respectively by It is limited in the left and right sides of bridge.Simultaneously as the steel guard rail of position-limited rack and bridge is connected together by limit card slot, therefore On the one hand position-limited rack then provides support force for suspension type platform, on the other hand can also limit the swing of suspension type platform or shake. And due to the unique structural advantage of portal frame, the lower section of portal frame has the space of open type, this space then can be used for vehicle Temporary traffic thus greatly alleviates traffic pressure.

Therefore, the present invention can be used not only for effectively supporting suspension type platform, meeting the construction of suspension type platform It is required that and do not need block bridge floor traffic, greatly alleviation traffic pressure.The configuration of the present invention is simple simultaneously, operation and maintenance It is very convenient, great popularization.

Detailed description of the invention

Fig. 1 is the operation platform integral installation structural schematic diagram in the present invention.

Specific embodiment

Present invention will be further explained below with reference to the attached drawings and examples:

As shown in Figure 1, a kind of bridge construction platform disclosed by the invention, two including being symmetrically disposed on 8 two sides of bridge Suspension type platform 10, along two track girders being parallel to each other of the longitudinally fixed laying of bridge floor and the dragon being slidably connected with track girder Door frame 2.Portal frame 2 is spliced and combined by steel truss, its own is with certain gravity.The lower end of portal frame 2 is equipped with rolling Wheel, portal frame 2 are slidably connected by idler wheel and track girder.When needed, the propelled longitudinally portal frame 2 of track girder can be drilled, this Sample portal frame 2 can move back and forth along the longitudinal direction of bridge 8.Suspension type platform 10 used in this programme, in the prior art Construction operation platform, such as the operating platform using steel plate and channel steel welding or the operation welded using reinforcing bar and fashioned iron Platform etc., to suspension type platform 10, there is no restriction in the present case.

Suspension type platform 10 is fixedly installed with position-limited rack 6 close to the side of portal frame 2, position-limited rack 6 close to portal frame 2 one Side is equipped with downward opening limit card slot 7, and steel guard rail 9 clamping and the position-limited rack 6 of the limit card slot 7 with bridge 8 pass through limit Card slot 7 and steel guard rail 9 form the structure being slidably connected.Wirerope 1, wirerope 1 are equipped between portal frame 2 and suspension type platform 10 One end be fixedly connected with the top of portal frame 2, the other end is fixedly connected with the top of suspension type platform 10；Two suspension types are flat It is equipped with support rod 5 between platform 10, the both ends of support rod 5 are hinged or be bolted with two suspension type platforms 10 respectively.Portal frame 2 It is up-narrow and down-wide, and limit for height board 4 and construction indicator light 3 are installed on the portal frame 2.The both ends of support rod 5 are outstanding with two respectively Hanging type platform 10 is hinged.Crashworthy plate is hung on support rod 5.
