Abstract
The utility model discloses a crab base-supporting type loading-unloading bridge. The crab base-supporting type loading-unloading bridge is mainly characterized in that the crab is hung under a main beam adopting a base-supporting type, and the crab base-supporting type loading-unloading bridge adopts a big car top-supporting type balancing device. The utility model has the advantages that the structure of the crab is simple, the maintenance is convenient, the fixed incline center of the crab is low, the stability is high, the use is safe, the lifetime of a truss is lengthened, the strength of the big car frame is improved by the big car top-supporting type balancing device, and the service life of the big car is lengthened.
Description
The utility model relates to a kind of lifting handler, the handling bridge of bearing-type under particularly a kind of dolly.
At present, existing handling bridge dolly adopts the pattern that goes up unitary construction without exception, and promptly dolly is contained in the girder top.There are many problems in this class handling bridge in using, as dolly for by the bridge leg to the operation of cantilever place, the necessary split manufacturing of girder, many with steel and complex structure, aloft wind area is big to add several meters high box girder, be subjected to very big wind load very dangerous, dolly metacenter height in addition, poor stability.Relevant by retrieval document still finds no and the same or analogous record of the utility model.
The purpose of this utility model is to provide the handling bridge of bearing-type under a kind of dolly.
Technical solution of the present utility model is exactly the below that bearing mode was arranged on girder under dolly adopted, and girder adopts truss structure, and the top that bearing mode is installed in big vehicle frame is gone up in the employing of the equalizer of cart.
The utility model has been broken through the pattern of unitary construction in the same employing of handling bridge dolly in the past in the dolly design, adopted the structure of time bearing-type underslung trolley, the dolly simple structure, cost is low, and maintenance is convenient, has reduced metacenter, good stability, safe and reliable; In the cart design, adopted eight to take turns the bearing-type equalizer, reduced wheel load, prolonged the service life of driving wheel.The utility model modern design is easy to implement, and has improved the safety of handling bridge work.
Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is a structure side view of the present utility model;
Fig. 3 is the connection structure scheme drawing of dolly and truss;
Fig. 4 goes up bearing-type equalizer structural representation.
With reference to accompanying drawing, girder adopts truss structure, and the utility model comprises cart 1, dolly 2, truss 3 and supporting leg 4, and truss 3 adopts the one design, and metal construction is stressed rationally, and is in light weight, saves steel 1/3rd than box girder.Dolly 2 following bearing modes are suspended on the below of truss 3, truss lower edge 7 adopts I-beam section to make, and truss lower edge 7 upper berths are welded with the dolly track 8 that steel plate is made, just motion on dolly track 8 of carriage walking wheel 9, because the carriage walking wheel does not grind the truss lower edge, has prolonged the truss life-span.In the cart design, the load-bearing axle that has changed traditional handling bridge cart equalizer is arranged on the structure in the big vehicle frame, cart 1 adopts goes up the bearing-type equalizer, it is the top that equalizer 5 is arranged on big vehicle frame 6, link together with load-bearing axle 10 between the two, load-bearing axle 10 is positioned at the top of big vehicle frame 6, has kept the integraty of big body frame structure for automotive, improve the intensity of big vehicle frame, prolonged the service life of cart.
Claims (2)
1, the handling bridge of bearing-type under a kind of dolly comprises cart, dolly, girder and supporting leg, it is characterized in that dolly adopts following bearing mode to be arranged on the below of girder.
2, the handling bridge of bearing-type under the dolly as claimed in claim 1 is characterized in that the equalizer of cart is arranged on the top of big vehicle frame.
