Abstract
The invention provides a two-beam bridge crane which is not easily limited by the plant height and is convenient to maintain. In order to solve the technical problems, the two-beam crane provided by the invention comprises a trolley and a hoisting mechanism, wherein the hoisting mechanism is mounted at the lower part of the trolley; a telescopic hydraulic cylinder is arranged on the lower end surface of the trolley; and the hoisting mechanism is arranged on the telescopic hydraulic cylinder. The position of the hoisting mechanism is adjusted through the telescopic hydraulic cylinder so that the hoisting mechanism is lower than a plant; and the hoisting mechanism is elevated as much as possible to facilitate maintenance. With reduced overall height, the two-beam crane provided by the invention can adapt to multiple plant environments, and the limit of plant height is reduced.
Description
Technical field
The present invention relates to crane, be specifically related to a kind of double girder overhead crane.
Background technology
General-purpose overhead crane because of its bearing capacity large, the advantages such as good stability are widely used in various types of workshops, factory building and warehouse. Its lifting mechanism is generally all arranged on the top of running trolley, and part factory building, because ignoring the restriction of headroom height, in the time of erection crane, has run into the difficult problem that crane small cart frame and workshop steel structure are interfered, and cannot meet the needs of installation; Install if reduce the orbit altitude of double girder crane, larger to the lifting altitude loss of used double girder crane, give and use enterprise to bring greater inconvenience.
Carry out mill construction change difficulty large, workload is heavy, therefore, can reduce complete machine height by the bottom that lifting mechanism is installed to trolley frame, but this method diminishes the space of lifting mechanism in trolley frame, has brought inconvenience to maintenance.
Summary of the invention
The invention provides one and be not subject to factory building height restriction, and the double girder overhead crane of convenient for maintaining.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of double girder crane, comprises dolly 1, lifting mechanism 2, and the bottom of dolly 1 is provided with lifting mechanism 2, it is characterized in that, is provided with telescopic hydraulic cylinder 3 on the lower surface of dolly 1, and lifting mechanism 2 is arranged on telescopic hydraulic cylinder 3.
By the adjust hoisting position of mechanism of telescopic hydraulic cylinder, make its height lower than factory building height, and heighten lifting mechanism convenient for maintaining as far as possible.
Complete machine height of the present invention reduces, and goes for multiple power house environment, reduces factory building height restriction.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
Fig. 1 is 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 double girder crane, comprises dolly (1), lifting mechanism (2), the bottom of dolly (1) is provided with lifting mechanism (2), it is characterized in that, on the lower surface of dolly, be provided with telescopic hydraulic cylinder (3), lifting mechanism (2) is arranged on telescopic hydraulic cylinder (3).
By the adjust hoisting position of mechanism of telescopic hydraulic cylinder, make its height lower than factory building height, and heighten lifting mechanism convenient for maintaining as far as possible.
Complete machine height of the present invention reduces, and goes for multiple power house environment, reduces factory building height restriction.
