Abstract
The invention relates to a crane for mounting a bridge curtain board, which comprises a main structure frame, a hoist crane guide beam, a front hoist crane and a rear hoist crane. The main structure frame is provided with a front supporting upright post and a rear supporting upright post, the hoist crane guide beam is installed at the middle position of the upper end face of the main structure frame, and the front end of the hoist crane guide beam extends out of the main structure frame. The front hoist crane and the rear hoist crane are sequentially installed on the hoist crane guide beam, the rear support upright post is provided with a balance weight, the front support upright post is provided with a guide wheel, and the rear support upright post is provided with a fixed wheel. The invention has simple structure, low cost and convenient maintenance. The crane is closely combined with the installation and construction process of the passenger dedicated line bridge curtain board, and through field test tests, the crane can meet the requirement of curtain board installation accuracy, is simple and convenient to operate, and does not influence the development of other construction operations.
Description
Technical field
The invention belongs to the erecting device of Passenger dedicated railway Bridge shield, relate 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 patent of invention 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.
Summary of the invention
Main purpose of the present invention 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 solution adopted in the present invention 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.
Beneficial effect of the present invention is: the present invention 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 of the present invention;
Fig. 2 is the front view that is used for the crane of mounting bridge shield plate of the present invention.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
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 invention is not restricted to the foregoing description; to those skilled in the art, any conspicuous improvement that the above embodiment of the present invention is made or change can not exceed the embodiments of the invention that only illustrate by way of example and the protection domain of claims.
