Abstract
The utility model relates to a kind of door frame of span winch, it is characterized in that it comprises end carriage (1), crossbeam (2), digonal link (3) and cylinder (4), described end carriage (1) totally two, be symmetrically arranged in respectively on the orbit of hoisting crane, and one of them end carriage (1) is positioned at harbour outer place, described crossbeam (2) is arranged on two end carriages (1), described cylinder (4) is arranged on crossbeam (2), and that side beam (1) place be arranged near harbour outer, described digonal link (3) totally two, its one end connecting cross beam (2) other end connects cylinder (4), form a firm integral structure.The utility model has higher stability under equality strength, rigidity condition compared with the door frame of routine, and reduces door frame steel material used, reduces complete machine cost simultaneously, also reduce further the energy consumption of complete machine.
Description
Technical field
The utility model relates to a kind of structure of span winch.Particularly relate to a kind of portal-framed structure of span winch.Belong to the technical field of elevator machinery.
Background technology
Span winch, as the important weight-lifting equipment of port and pier, is mainly engaged in the loading and unloading operation of breakbulk, and it has frequency of utilization frequently, higher work speed, and this proposes very high requirement to the steel structure part of hoisting crane.Because alongside is different in the boats and ships molded breadth of harbour, make the work range of the span winch of handling goods also be different, in recent years because the use of large ship gets more and more, molded breadth is also comparatively large, and the work range of corresponding requirements span winch is also larger.
Before the utility model makes, the cylindrical structure of traditional gate seat portal gantry is the center (its structure is shown in Fig. 1) occuping two span winch orbit spacing, i.e. the center of gyration of span winch and gauge center superposition.In order to meet the larger work range requirement of span winch complete machine, then require that span winch jib is longer, the steel plate thickness of use is thicker, and materials'use amount is also more, and complete machine is from great, and fabrication cost is high, also large to the energy consumption of complete machine.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, there is provided a kind of and the effective work range increasing span winch both can be provided, the materials'use amount of complete machine can be reduced again, reduce complete machine cost, reduce complete machine energy consumption, the span winch door frame of intensity and rigidity requirement can also be met.
The purpose of this utility model is achieved in that a kind of door frame of span winch, it comprises end carriage, crossbeam, digonal link and cylinder, described end carriage totally two, be symmetrically arranged in respectively on the orbit of hoisting crane, and one of them end carriage is positioned at harbour outer place, described crossbeam is arranged on two end carriages, described cylinder is arranged on crossbeam, and that side Liang Chu be arranged near harbour outer, described digonal link totally two, its one end connecting cross beam other end connects cylinder, forms a firm integral structure.
Compared with prior art, the beneficial effects of the utility model are:
The utility model its effective work range when equal jib amplitude is larger, can load and unload larger wide boats and ships.Under equality strength, rigidity condition, there is compared with the door frame of routine higher stability, and reduce door frame steel material used, reduce complete machine cost simultaneously, also reduce further the energy consumption of complete machine.
