The utility model discloses full play gantry crane walks capable convenient, hoist and mount convenient advantage, utilizes the truss structure at gantry crane top as insulating protector's welding fulcrum simultaneously, and insulating protector is safe firm, has solved under the high-voltage line difficult problem of bridge hoist and mount operation when safe headroom is not enough.
Description
Technical Field
The utility model belongs to the technical field of the construction of city bridge and specifically relates to an insulating protection gate-type jack-up hoist device when safe headroom is not enough under high-voltage line is related to.
Background
Along with the increasing development of economy and the increasing expansion of urban construction scale in China, the construction of urban bridges is also a necessary facility for urban planning, and in the construction process of the upper structure of the urban bridges, the phenomenon of insufficient clearance under high-voltage lines along the line often exists, so that great potential safety hazards exist for bridge construction; in the construction process of the conventional urban bridge, on the road section affected by insufficient clearance of the high-voltage line, construction can be performed after the high-voltage line is changed into the ground, and the construction progress of the bridge is influenced to a certain extent.
In view of this, in order to avoid the influence on the bridge construction caused by insufficient clearance of the high-voltage line, besides reasonably formulating the construction period in the construction planning, how to ensure the construction safety and progress of the urban bridge when the high-voltage line is not changed to the ground in time becomes a problem to be considered in the present urban bridge construction design.
Disclosure of Invention
An object of the utility model is to provide an insulating protection gate-type jack-up hoist device that still can guarantee city bridge's construction safety and progress, construction are convenient, simple structure, safe firm under the high-voltage line when safe headroom is not enough.
The purpose of the utility model is realized like this:
the utility model provides an insulating protection portal crane hoisting device when safe headroom is not enough under high-voltage line, including satisfying the portal crane of bridge jack-up hoist and mount ability, portal crane is by the track, bearing structure down, truss girder and hoisting trolley constitute, at no high-voltage line region with treat that the track of construction area installation portal crane according to portal crane's span, install bearing structure down on the track of portal crane in no high-voltage line region, truss girder and hoisting trolley, the gyro wheel of bearing structure bottom is located on the track down, the characteristic is: a set of flange tripod is fixed on each of the front side and the rear side of the truss girder, the two flange tripods are identical in structure and symmetrical to each other, an insulating protection plate is laid on the flange tripods, insulating protection covers are laid on the two sides and the top of the hoisting trolley, and the insulating protection plates and the insulating protection covers form an insulating protection device.
The insulating protection plate is inclined 5-10 degrees to the lower side of the outer side, so that water is drained conveniently.
The utility model discloses an insulating protection portal crane hoist device when safe headroom is not enough under high-voltage line sets up the insulating protector who bears the insulation board dead weight, wind and rain load respectively at the lateral part and the top of portal crane's truss, just so has just so full play portal crane walks capable convenience, hoist and mount convenient advantage, utilize portal crane's truss structure as insulating protector's welding fulcrum simultaneously, insulating protector is safe firm, the difficult problem of bridge hoist and mount operation when safe headroom is not enough under the high-voltage line has been solved.
Therefore, the utility model has the advantages of still can guarantee city bridge's construction safety and progress, construction convenient, safe firm, simple structure when safe headroom is not enough under the high-voltage line.
