Description
Technical field
It the utility model is related to technical field of crane equipment, and in particular to a kind of double girder overhead traveling cranes of double trolley types of extension partially
Machine.
Background technology
Former dolly of hanging partially is applied to use on outdoor single girder door machine, if crane originally, which will be realized, is combined what is lifted
Function needs, and to set 2 dollies in girder, 2 dollies are usually located at two girder middle positions, and suspension hook is located in girder
Side, and two suspension centres are oriented parallel to girder, this allows for crane larger allocation and transportation blind area on factory building span direction.
Because allocation and transportation object is parallel to girder, operating personnel observe on drivers' cab, drop point is inconvenient.And if it is desired to realizing that suspension centre hangs down
Directly in girder, then need to design a dolly, 2 lifting mechanisms be set on the dolly, when lift object it is longer when, small track
Very big away from meeting, dolly weight also can be very big.On the one hand waste of material is caused, while crane deadweight is excessive, can also influence lifting
The service life of machine.
In addition, side of the inclined extension dolly used on single girder door machine due to hanging over corresponding girder partially, hangs dolly load-bearing partially
Larger tilting moment is formed afterwards, so horizontal reaction wheel is provided with the top of trolley frame, and the support beam below trolley frame
Bottom be provided with horizontal support roller, wherein, the side of the track at the top of horizontal reaction wheel and corresponding girder, which rolls, to be coordinated, and water
Flat back-up roller wheel then rolls with the side of girder to be coordinated, and the trolley frame hung partially is matched somebody with somebody by horizontal reaction wheel and horizontal support roller
Close to overcome larger tilting moment to ensure the normal work of extension dolly partially.But once horizontal support roller breaks down and nothing
When normal direction trolley frame provides support force, dolly is hung partially without normal direction only according to horizontal reaction wheel the anti-dumping for preventing that extension dolly is tumbled partially is provided
Torque is turned over, dolly is hung partially and overthrow accident easily occurs, security is poor." crane is used to hang dolly partially and use to be somebody's turn to do Chinese patent
The crane of dolly is hung partially "（Application number 201320543880.8）Although being improved to anti-tilting apparatus, structure is very
It is complicated.In a word, it is existing partially hang dolly anti-tilting apparatus mainly for single dolly, or and anti-tipping effect it is poor,
The structure of anti-tilting apparatus is sufficiently complex.
Utility model content
The technical problems to be solved in the utility model is, existing crane combined larger allocation and transportation to be present when lifting blind
Area, and existing dolly anti-tilting apparatus of hanging partially are mainly for single dolly, or and anti-tipping effect it is poor, or it is anti-
The defects of structure of tipple is sufficiently complex.
The purpose of this utility model is to provide a kind of double girder bridge cranes of double trolley types of extension partially, including dolly, girder
And traveling mechanism of the larger traveller, the dolly movement are assemblied in girder upper surface, girder upper surface is provided with track, and dolly includes dolly
Frame, it is provided with trolley frame and rolls the road wheel coordinated with girder upper surface track, trolley frame is extended on the outside of girder, described small
Car includes the first dolly and the second dolly, and the girder includes the first girder and the second girder, and the first dolly is assemblied in the first master
Liang Shang, the second dolly are assemblied on the second girder.
First straight up is provided with the position that the trolley frame of first dolly is extended on the outside of the first girder
Brace, the second support arm straight up, institute are provided with the position that the trolley frame of the second dolly is extended on the outside of the second girder
State the first support arm and the second support arm is connected by linking arm, the linking arm is scalable.
Retractor device is provided with the linking arm, the retractor device includes the slide-bar and axle sleeve that vertical girder is set,
The axle sleeve is set in outside the slide-bar.
The slide-bar and axle sleeve are removably attached on linking arm.
First support arm includes more than one and is set in parallel on the trolley frame of the first dolly, second support
Arm includes more than one and is set in parallel on the trolley frame of the second dolly.
First dolly divides into the first suspension hook, and the first suspension hook is arranged on the outside of the first girder, and the second dolly divides into the second suspension hook,
Second suspension hook is arranged on the outside of the second girder.
Relative to prior art, technique effect of the present utility model is that a kind of double trolley types of extension partially of the present utility model are double
Girder bridge crane, the first dolly and the second trolley function are flexible, can be used alone, and can also work together.When needing to join
The first dolly and the second dolly can be run simultaneously when lifting, same liter is same drops, vertical with girder by the length direction of allocation and transportation object,
Operating personnel in drivers' cab can conveniently observation lifting workpiece landing point, avoid crane on factory building span direction exist compared with
Big allocation and transportation blind area and the security incident triggered.In addition, to collectively constitute first small for the first support arm, the second support arm and linking arm
The anti-tilting apparatus of car and the second dolly, avoid dolly that security incident occurs because tumbling in the process of running.
