Abstract
The invention provides a double-beam bridge crane not limited by factory building height and convenient to maintain. The technical scheme includes that the crane comprises two symmetric main beams, a trolley and a hoisting mechanism. Steps are arranged on the inner opposite sides of the two main beams, trolley rails are arranged on the upper end faces of the steps, the hoisting mechanism is mounted on the lower portion of the trolley, a telescopic hydraulic cylinder is arranged on the lower end face of the trolley and the hoisting mechanism is positioned above the telescopic hydraulic cylinder. The crane has the advantages that the trolley rails are arranged on the inner sides of the main beams, descending height of the trolley can be adjusted, the distance of the two main beams can be adjusted in a factory building, and the height of a trolley frame is adjusted by disposing wheels of the trolley frame on the rails of the inner sides of the main beams; the position of the hoisting mechanism is adjusted through the telescopic hydraulic cylinder, so that the hoisting mechanism is lower than the factory building, and maintenance is facilitated by heightening the hoisting mechanism.
Description
Technical field
The present invention relates to crane, be specifically related to a kind of double girder overhead crane.
Background technology
The advantages such as general-purpose overhead crane is big because of its bearing capacity, good stability are widely used in various types of workshop, Factory Building and warehouse. Its lifting mechanism is generally all arranged on the top of running trolley, and part Factory Building is because ignoring the restriction of headroom height, when erection crane, encounters the difficult problem that crane small cart frame is interfered with workshop steel structure, it is impossible to meet the needs installed; If the orbit altitude reducing double girder crane is installed, the lifting altitude of the double girder crane used is lost relatively big, gives and use enterprise to bring greater inconvenience.
Carry out mill construction change difficulty big, workload is heavy, therefore, the structure of modification to traditional common bridge machine can be passed through, reduce complete machine height, solve this difficult problem, lifting mechanism can be installed to the bottom of trolley frame to reduce complete machine height simultaneously, but this method makes the space of lifting mechanism in trolley frame diminish, and brings inconvenience to maintenance.
Summary of the invention
The invention provides one and be susceptible to factory building height restriction and the double girder overhead crane of convenient for maintaining.
In order to solve above-mentioned technical problem, the present invention adopts the following technical scheme that
A kind of crane, including two girders 1, dolly 2, lifting mechanism 3, the inner side that mutually symmetrical with and described two girders 1 of described two girders 1 are relative is set to ladder 4, described ladder 4 upper surface is provided with the track 5 of described dolly 2, the bottom of dolly 2 is provided with lifting mechanism 3, it is characterized in that, the lower surface of dolly 2 is provided with telescopic hydraulic cylinder 6, and lifting mechanism 3 is arranged on telescopic hydraulic cylinder 6.
Trolley track is arranged on inside girder by the present invention, dolly may select the height of decline, the distance of two girders is regulated in Factory Building, trolley frame wheel is placed on the track inside girder, regulate the height of trolley frame, adjusted hoisting by telescopic hydraulic cylinder the position of mechanism simultaneously so that it is height is lower than factory building height, and heightens lifting mechanism convenient for maintaining as far as possible.
The complete machine height reduction of the present invention, it is possible to suitable in multiple power house environment, reduces factory building height restriction.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is the schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
A kind of crane, including two girders (1), dolly (2), lifting mechanism (3), the relative inner side of mutually symmetrical with and described two girders (1) of described two girders (1) is set to ladder (4), described ladder (4) upper surface is provided with the track (5) of described dolly (2), the bottom of dolly (2) is provided with lifting mechanism (3), it is characterized in that, being provided with telescopic hydraulic cylinder (6) on the lower surface of dolly (2), lifting mechanism (3) is arranged on telescopic hydraulic cylinder (6).
Trolley track is arranged on inside girder by the present invention, dolly may select the height of decline, the distance of two girders is regulated in Factory Building, trolley frame wheel is placed on the track inside girder, regulate the height of trolley frame, adjusted hoisting by telescopic hydraulic cylinder the position of mechanism simultaneously so that it is height is lower than factory building height, and heightens lifting mechanism convenient for maintaining as far as possible.
The complete machine height reduction of the present invention, it is possible to suitable in multiple power house environment, reduces factory building height restriction.
