Abstract
The utility model discloses a trussed gantry crane, comprising a portal main frame structure which is composed of left and right landing legs and a girder, wherein left and right track walking mechanisms are respectively arranged at the lower ends of the left and right landing legs; the girder is a trussed single girder; two walking guide rails are arranged on the girder in parallel along the longitudinal direction; a walking crown block driven by a power source is arranged on each walking guide rail; left and right hoisting mechanisms are symmetrically arranged on the walking crown blocks; balance suspension girders with hangers are suspended below the left and right hoisting mechanisms through wire ropes; and an electric hoist lifting device is suspended below the girder. The trussed gantry crane has the advantages that a single-girder and dual-track structure is adopted, the dead load is relatively light, and the manufacturing cost is greatly reduced; independent double hoisting mechanisms are adopted on the walking crown blocks, and hoisting is stable by using a dual-hanging point mechanism, so that the work efficiency is improved; and meanwhile, the electric hoist lifting device playing an auxiliary role is arranged below the girder, so that the hoisting and operating processes are more stable and ordered.
Description
Technical field
The utility model relates to weight-lifting equipment, especially relates to a kind of truss-like gauntry crane.
Background technology
The truss-like gauntry crane that the operating areas such as traditional upset during for wind-power electricity generation, large-size pipe welding, harbour, harbour cargo handing match, generally all adopt two main beam structures, the walking overhead traveling crane is being installed by track above two girders and by the winch on the walking overhead traveling crane, workpiece is being carried out to lifting operation, but the deadweight of the hoisting crane of this structure is larger, greatly increased manufacturing cost, and it is larger easily to occur that in the lifting process workpiece swings, move jiggly phenomenon, have certain potential safety hazard.
Summary of the invention
It is a kind of simple in structure that the utility model purpose is to provide, lifting pulsation-free truss-like gauntry crane.
For achieving the above object, the utility model can be taked following technical proposals:
Truss-like gauntry crane described in the utility model, comprise the gate-type main frame structure formed by left and right supporting leg and girder, be respectively arranged with left and right track running mechanism in described left and right supporting leg lower end, described girder is truss-like list girder, longitudinally be arranged with two walking guide rails in parallel on described girder, be provided with the walking overhead traveling crane that propulsion source drives on described walking guide rail, be symmetrically arranged with left and right hoisting mechanism on described walking overhead traveling crane, below described left and right hoisting mechanism, by wire rope suspensioning, the balance hanging beam with suspender arranged.
Below described girder, suspention has electric hoist lifting device.
The utility model advantage is to adopt single girder to join the two-orbit structure, conducts oneself with dignity lighter, thereby greatly reduces manufacturing cost; And adopt independently double hoisting mechanism on the walking overhead traveling crane, utilize pair suspension centre mechanism lifting steadily, improved work efficiency; Below girder, one of configuration plays complementary electric hoist lifting device simultaneously, makes lifting and operational process more steadily in order, and the utility model also can be made maintenance lifting main equipment and use.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left TV structure schematic diagram of Fig. 1.
The specific embodiment
As Fig. 1, shown in 2, truss-like gauntry crane described in the utility model, comprise by left branch leg 1, the gate-type main frame structure that right supporting leg 2 and girder 3 form, on a described left side, right supporting leg 1, 2 lower ends are respectively arranged with a left side, right track running mechanism 4, 5, described girder 3 is truss-like list girder, longitudinally be arranged with two walking guide rails 6 in parallel on described girder 3, be provided with the walking overhead traveling crane 7 that propulsion source drives on described walking guide rail 6, be symmetrically arranged with a left side on described walking day 7 cars, right hoisting mechanism 8, 9, on a described left side, right hoisting mechanism 8, there is the balance hanging beam 11 with suspender 10 9 belows by wire rope suspensioning, below described girder 3, suspention has electric hoist lifting device 12, the utility model adopts single girder to join the two-orbit structure, conducts oneself with dignity lighter, thereby greatly reduces manufacturing cost, has saved material and the energy, meets " increasing income and decreasing expenditure, energy-saving and emission-reduction " policy of country, and adopt independently double hoisting mechanism on walking overhead traveling crane 7, utilize pair suspension centre mechanism lifting steadily, improved work efficiency, below girder 3, one of configuration plays complementary electric hoist lifting device 12 simultaneously, makes lifting and operational process more steadily in order, and the utility model also can be made maintenance lifting main equipment and use.
