Abstract
The utility model relates to a crane for mounting a bridge shielding plate, which comprises a main structure frame, a hoist guiding beam, a front hoist and a rear hoist, wherein the main structure frame is provided with a front support upright post and a rear support upright post; the hoist guiding beam is arranged in the middle of the upper end surface of the main structure frame, and the front end extends out of the main structure frame; the front hoist and the rear hoist are respectively arranged on the hoist guiding beam; the rear support upright post is provided with a counterweight; the front support upright post is provided with a guide wheel; and the rear support upright post is provided with a fixing wheel. The utility model has the advantages of simple structure, low cost and convenient maintenance. The utility model is closely matched with the mounting and construction process of the bridge shielding plate of the passenger dedicated line; after being tested by on-site experiment, the utility model can satisfy the mounting precision requirement of the shielding plate, is convenient to operate, and does not affect the conduction of the other construction operations.
Description
Technical field
The utility model belongs to the erecting device of Passenger dedicated railway Bridge shield, relates in particular to a kind of crane that is used for mounting bridge shield plate.
Background technology
Railway line for passenger traffic bridge floor shield quality is about 500kg, only depends on manpower can't implement its erection work.But,, need construction continuously because shield is to be provided with continuously on bridge floor, if adopt general-utility car to hang installation, the installation in position precision is difficult to control on the one hand, and to hang floor area big for general-utility car on the other hand, must influence carrying out of other construction operations, thereby influence construction speed.The patent No. is 200720191945, denomination of invention discloses a kind of crane technical scheme for the utility model patent of " simple and easy rail mounted cantilever telpher ": it comprises cantalever rod bearing, cantalever rod, pulley, wirerope lifting rope and lifting rope capstan winch, and the bottom of cantalever rod bearing is provided with guide tracked base, and two bottom side of cantilevered boom support are equipped with the roller that matches with the guide rail of guide tracked base.Though this kind crane can be realized the carrying of object, but still need manpower to participate in, also fail fundamentally to solve weight is placed to this difficult problem of desired location.
The utility model content
Main purpose of the present utility model is to reduce manual work intensity, realizes the continuous construction operation of bridge floor shield, does not influence carrying out of other construction operations simultaneously.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of crane that is used for mounting bridge shield plate comprises that main structural frame, cucurbit hang nose girder, preceding cucurbit hangs and the back cucurbit hangs.Described main structural frame has support post behind two preceding support posts and two, and main structural frame forms crane main stress structure, guarantees the shield mounting stability.Described cucurbit hangs that nose girder is installed on the midway location of main structural frame upper surface and front end that cucurbit hangs nose girder extends main structural frame.Cucurbit hangs and the back cucurbit hangs and is installed on cucurbit successively and hangs on the nose girder before described, and the two coordinative operation is used to lift the cement concrete shield, and preceding cucurbit hangs and the back cucurbit hangs and can be chosen as electronic as required or manually all can.
Described main structural frame hangs on the back support post of nose girder rear end near cucurbit counterweight is installed, to keep the balance of crane car body when the lifting shield.
On the support post track adjusting wheel is installed before described.On the support post of described back tight pulley is installed, the direct of travel of tight pulley hangs nose girder perpendicular to cucurbit.Can easily crane be carried out integral body by track adjusting wheel and tight pulley moves.
The preceding support post of main structural frame and back support post spacing are about 2.6m, can make crane to move across the crashproof wall of bridge deck concrete, thereby not influence carrying out of other construction operations.
The beneficial effects of the utility model are: the utility model is simple in structure, and cost is low, and is easy to maintenance.The installation process of the Passenger dedicated railway Bridge of combining closely shield by in-place test test, uses this crane can satisfy the requirement of shield setting accuracy, and is not easy and simple to handle, not and influence carrying out of other construction operations.
Description of drawings
Fig. 1 is the lateral plan that is used for the crane of mounting bridge shield plate described in the utility model;
Fig. 2 is the front view that is used for the crane of mounting bridge shield plate described in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
In conjunction with illustrated in figures 1 and 2, a kind of crane that is used for mounting bridge shield plate, comprise main structural frame, cucurbit hang nose girder 2, preceding cucurbit hang 4 and the back cucurbit hang 3.Described main structural frame has support post 1 behind two preceding support posts 5 and two, and main structural frame forms crane main stress structure, guarantees the shield mounting stability.Described cucurbit hangs that nose girder 2 is installed on the midway location of main structural frame upper surface and front end that cucurbit hangs nose girder 2 extends main structural frame, makes the action radius of handling shield further stretch out.Before described cucurbit hang 4 and the back cucurbit hang 3 and be installed on cucurbit successively and hang on the nose girder 2, the two coordinative operation is used to lift the cement concrete shield, preceding cucurbit hang 4 and the back cucurbit hang 3 and can be chosen as electronic as required or manually all can.
Described main structural frame hangs on the back support post 1 of nose girder 2 rear ends near cucurbit counterweight 8 is installed, to keep the balance of crane car body when the lifting shield.On the support post 5 track adjusting wheel 6 is installed before described.On the support post 1 of described back tight pulley 7 is installed, the direct of travel of tight pulley 7 hangs nose girder 2 perpendicular to cucurbit.Can carry out integral body to crane easily by track adjusting wheel 6 and tight pulley 7 moves.
During use, earlier crane is moved to the desired location, tight pulley 7 and track adjusting wheel 6 are carried out stationkeeping; Before re-using cucurbit hang 4 and the back cucurbit hang 3 and cooperate the lifting shields, and hang nose girder 2 along cucurbit and proceed to the installation site; At last shield being positioned over the desired location gets final product.
The utility model is not limited to the foregoing description; to those skilled in the art, any conspicuous improvement that the foregoing description of the present utility model is made or change can not exceed the embodiment of the present utility model that only illustrates by way of example and the protection domain of claims.
