Abstract
The utility model discloses a low-height bridge crane, and relates to the hoisting machinery. By adoption of the low-height bridge crane, the problem that the existing bridge crane can not meet the requirement for the height limitation of the crane at specific can be solved. The low-height bridge crane comprises a bridge frame, a crane operating mechanism, a trolley frame and a hosting mechanism, wherein the bridge frame consists of two box-type main beams and two end beams; the crane operating mechanism is connected with the bridge frame; the trolley frame operates on a track of the bridge frame and is provided with a trolley operating mechanism; the hoisting mechanism is arranged on the trolley frame; the length direction of a winding drum of the hoisting mechanism is same as the length direction of the box-type main beam; the hoisting mechanism is arranged on a lower platform of the trolley frame; the bridge frame adopts the hinged type end beams. The low-height bridge crane disclosed by the utility model has the advantages that the height space occupied by the hoisting mechanism is saved and the requirement for the height limitation of the crane at the specific occasions is met.
Description
Technical field
The utility model belongs to elevator machinery, particularly a kind of crane in bridge type of low clearance.
Background technology
Crane in bridge type generally is comprised of crane span structure, crane travel mechanism and dolly.Conventional crane span structure is comprised of two box type girders and two rigidity end carriages.During more than two, in order to reach the purpose that reduces wheel wheel load and wheel load equilibrium, generally two wheels are formed to an equalizer bar when the wheel quantity of crane travel mechanism, or again two equalizer bar Compositional balance jibs.The structure stacked by equalizer bar and balance jib like this coordinates with the rigidity end carriage, usually it is called to rigid ends beam bridge frame, and this structure will occupy larger height space.
Conventional monkey is comprised of trolley frame, wheeling mechanism and lifting mechanism.Lifting mechanism is arranged on trolley frame more than plane, and the reel length direction is arranged in and the girder vertical direction, and the height of dolly is trolley frame height dimension and lifting mechanism height dimension summation.
The crane in bridge type bottom-to-top-height is crane span structure height and dolly height sum, this rigid ends beam bridge frame of prior art and the combination of conventional structure dolly, and height dimension is larger, can not meet the requirement of particular place to the crane height restriction.
Summary of the invention
The purpose of this utility model is exactly in order to overcome the shortcoming of prior art, and a kind of low headroom overhead travelling crane is provided, and solves existing crane in bridge type and can not meet the problem of specific occasion to the crane height restriction.
Technical solutions of the utility model are for achieving the above object:
A kind of low headroom overhead travelling crane, comprise; The crane span structure formed by two box type girders and two butt beams, the crane travel mechanism be connected with crane span structure, operation on the crane span structure track, with the trolley frame of wheeling mechanism, be arranged on the lifting mechanism on trolley frame, it is characterized in that: the reel of described lifting mechanism, its length direction is identical with described box type girder length direction, and described lifting mechanism is arranged on the lower platform of described trolley frame, and described crane span structure adopts the radial type end carriage.
The utility model compared with the prior art, identical with the girder length direction due to lifting mechanism reel length direction is arranged in, and reduced the size that lifting mechanism occupies vehicle-width; Lifting mechanism is placed on the lower platform of trolley frame, makes the dimensional control of lifting mechanism vertex below trolley frame upper mounting plate height, lifting mechanism does not separately occupy height space.Simultaneously, crane span structure adopts the radial type end carriage, thereby greatly reduces the height dimension of hoisting crane.The utility model is compared with the conventional hoist structure, has saved the height space that lifting mechanism occupies, and has met the requirement of particular place to the crane height restriction.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the birds-eye view of Fig. 1;
Fig. 3 is the left view of Fig. 1;
Fig. 4 is the A-A cross section view of Fig. 1.
Below in conjunction with accompanying drawing, by preferred embodiment, the utility model is further described.
The specific embodiment
As shown in Figure 1,2,3, 4, a kind of low headroom overhead travelling crane, comprise; The crane span structure 1 formed by two box type girders and two butt beams, the crane travel mechanism 2 be connected with crane span structure 1, on crane span structure 1 track the operation, with the trolley frame 3 of wheeling mechanism, be arranged on the lifting mechanism 4 on trolley frame 3; The reel of described lifting mechanism 4, its length direction is identical with the girder length direction, and described lifting mechanism 4 is arranged on the lower platform of described trolley frame 3, and described crane span structure 1 adopts the radial type end carriage.
Because lifting mechanism reel length direction is identical with the girder length direction, lifting mechanism is placed on the lower platform of trolley frame simultaneously, make the dimensional control of lifting mechanism vertex below trolley frame upper mounting plate height, lifting mechanism does not separately occupy height dimension.The height dimension that the wheel tread of this low clearance dolly is above, be only that trolley frame height dimension and radial type end carriage crane span structure combine, and greatly reduces the height dimension of hoisting crane, and low headroom overhead travelling crane has met the operating needs of particular place.
