Abstract
The invention relates to an end beam structure of a truss type portal crane. The end beam structure is characterized by comprising connecting plates (1), external pillars (2), internal pillars (3) and lower cross beams (4), wherein the connection plates (1) are connected with the portal crane; one ends of the external pillars (2) are connected with the connecting plates (1), and the other ends of the external pillars are connected with the lower cross beams (4) through connecting parts; one ends of the internal pillars (3) are connected with the connecting plates (1), and the other ends of the internal pillars are connected with the lower cross beams (4) through the connecting parts; the lower cross beams (4) are mutually connected through the connecting parts; the end beam adopts a truss type structure. Compared with a box type end beam structure, the end beam adopting the truss type structure is smaller in wind load coefficient, needs less material under the same strength and stiffness condition, and is obviously reduced in the steel material consumption amount.
Description
Technical field
The present invention relates to a kind of end-beam arrangement of span winch door frame.The technical field that belongs to elevator machinery.
Background technology
The door frame of span winch is all structures of supporting top revolution part, the effect of the force of inertia that produces when bearing all deadweights of topside, Item Weight, wind-force and each mechanism (hoist, luffing, revolution and operation) motion and the moment that produced by these power, for guaranteeing the hoisting crane normal operation, door frame must have enough intensity, and larger rigidity will be arranged.
Before the present invention made, the end carriage (see figure 1) of traditional gate seat portal gantry was high in the middle of being, two ends low box component gradually.In order to satisfy the door frame spatial altitude, require the end carriage height higher, also large with the material amount, because its structure is casing, wind area is larger, and wind load is also large.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and both can effectively alleviate the material amount of using, can reduce again the truss-like span winch end carriage of wind area.
The object of the present invention is achieved like this: a kind of end-beam arrangement of truss-like span winch, it comprises connecting panel, outer pillar, interior pillar, cross sill, described connecting panel links to each other with span winch, one end of outer pillar links to each other with connecting panel, the other end links to each other with cross sill by attaching parts, and an end of interior pillar links to each other with connecting panel, and the other end links to each other with cross sill by attaching parts, link to each other by attaching parts between the cross sill, described end carriage is designed to the structure of truss-like.
Compared with prior art, the invention has the beneficial effects as follows:
Span winch end carriage of the present invention is the structure of truss-like, and it is little that wind carries the coefficient ratio box-structure, and materials lack than box-structure under equality strength, rigidity condition, significantly reduces used steel material.
Description of drawings
Fig. 1 is conventional span winch end carriage front view.
Fig. 2 is truss-like span winch end carriage front view.
Wherein:
Connecting panel 1
Interior pillar 3
Cross sill 4.
The specific embodiment
Referring to Fig. 2, the present invention relates to a kind of end-beam arrangement of truss-like span winch, comprise connecting panel 1, outer pillar 2, interior pillar 3, cross sill 4, described connecting panel 1 links to each other with span winch, and an end of outer pillar 2 links to each other with connecting panel 1, and the other end links to each other with cross sill 4 by attaching parts, one end of interior pillar 3 links to each other with connecting panel 1, the other end links to each other with cross sill 4 by attaching parts, links to each other by attaching parts between the cross sill 4, and described end carriage is designed to the structure of truss-like.
Claims (1)
