Abstract
The utility model provides a low bridge crane, relating to cranes and solving the technical problem that the heights of conventional cranes can not meet the low plant requirements of hydropower stations. The low bridge crane comprises a bridge, cart travel mechanisms, a crane trolley and cart travel tracks, wherein the bridge comprises left and right box girders and left and right trolley travel tracks; eight wheels of the cart travel mechanisms are respectively installed below the four corners of the bridge; the crane trolley is installed on the left and right trolley travel tracks; the cart travel tracks are installed on rail-bearing girders of a plant; the middle parts of the left and right box girders are concave downwards; the left and right trolley travel tracks are installed on the top surfaces of the concave parts. The low bridge crane is used on the special occasions of plants of hydropower stations, and has the advantages of reasonable structure and low cost.
Description
Technical field
The utility model relates to hoisting crane, is particularly suitable for that factory building height is low, the occasion of carrying heavy goods narrow range, for example the crane in bridge type of power station water turbine factory building.
Background technology
In power station, a lot of factory buildings are all on mountain, to dig cavern to build, and powerhouse of hydropower station hoisting crane requires bottom-to-top-height low for this reason.The girder end face of conventional hoisting crane is a horizontal surface, and trolley travelling track is arranged on girder end face, and monkey can move within the scope of whole girder.Owing to being subject to the restriction of material Strong degree, the height of crane girder has minimum limit value, and therefore, the bottom-to-top-height of conventional hoisting crane can not meet the requirement of present powerhouse of hydropower station.
Utility model content
The purpose of this utility model is intended to overcome the shortcoming of prior art, and a kind of low headroom overhead travelling crane is provided, and the bottom-to-top-height that solves conventional hoisting crane can not meet the technical matters that the low factory building in power station requires.
The utility model is achieved through the following technical solutions:
A kind of low headroom overhead travelling crane, comprise: crane span structure, traveling mechanism of the larger traveller, monkey, cart orbit, crane span structure is by left box type girder, right box type girder and left trolley travelling track mounted thereto, right trolley travelling track forms, traveling mechanism of the larger traveller is comprised of four groups of eight wheels, be arranged on respectively the below at four angles of crane span structure, monkey is arranged on left trolley travelling track, on right trolley travelling track, cart orbit is arranged on the support rail beam of factory building, it is characterized in that: described left box type girder, the middle part of right box type girder is in a concave shape, described left trolley travelling track, right trolley travelling track is arranged on recessed portion end face.
The utility model compared with prior art, because the girder middle part of hoisting crane is in a concave shape, trolley travelling track is only arranged on middle part recessed portion, its absolute altitude is far below conventional hoisting crane, not only greatly reduce the height of hoisting crane car load, also greatly reduce crane height more than crane track absolute altitude, also greatly reduce the height of factory building, reduced the total cost of hydropower project.
The utility model is for the special occasions of powerhouse of hydropower station, have rational in infrastructure, the advantage that cost is low.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation (front view) of low headroom overhead travelling crane;
Fig. 2 is the A-A section-drawing of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, by preferred embodiment, the utility model is described in further detail.
As Fig. 1, shown in 2, a kind of low headroom overhead travelling crane, comprise: crane span structure 1, traveling mechanism of the larger traveller 2, monkey 3, cart orbit 4, crane span structure 1 is by left box type girder 1-1, right box type girder 1-2 and left trolley travelling track 1-3 mounted thereto, right trolley travelling track 1-4 forms, traveling mechanism of the larger traveller 2 is comprised of four groups of eight wheels, be arranged on respectively the below at four angles of crane span structure 1, monkey 3 is arranged on left trolley travelling track 1-3, on right trolley travelling track 1-4, cart orbit 4 is for carrying the weight of whole hoisting crane, be arranged on the support rail beam of factory building, described left box type girder 1-1, right box type girder 1-2 middle part is in a concave shape, described left trolley travelling track 1-3, right trolley travelling track 1-4 is arranged on recessed portion end face.
Because left trolley travelling track 1-3, right trolley travelling track 1-4 are arranged on the end face of left box type girder 1-1, right box type girder 1-2 recessed portion, the more conventional hoisting crane of setting height(from bottom) of monkey 3 reduces greatly, the also corresponding reduction of the car load height of hoisting crane.So just realized the object that reduces hoisting crane car load height.Can only be in the operation of girder recessed portion because of monkey 3, therefore the scope of its handling weight and conventional hoisting crane are narrow, but for the powerhouse of hydropower station hoisting crane of lifting rotor, the utility model can meet handling scope.
