Description

A kind of supporting leg dish device for portal crane
Technical field
The utility model relates to technical field of engineering machinery, particularly relates to the stabilizer plate device of a kind of harbour movable crane.
Background technology
Harbour movable crane is a kind of high-mobility, multipurpose, wheeled vehicle weight-lifting equipment being widely used in the facilitated transition of the handlings such as harbour container, groceries and bulk goods.Owing to having good manoevreability, applicability and economy, be used widely in harbour abroad.
Consider the deadweight of harbour movable crane and the large feature of work range, its Work places is the harbour at harbour or trestle mainly.For medium and small tonnage harbour movable crane, every bar movable supporting legs, by single leg disc and earth surface power transmission, can meet its stability requirement, can not have an impact again to harbour or trestle work structure.
But for large-tonnage harbour movable crane, because rated load weight is large, if each supporting leg is by single leg disc and earth surface power transmission, damaging influence certainly will be produced to harbour or trestle work structure.
Therefore, how improving the ground contact area of large-tonnage harbour movable crane leg disc, increase the stability of its work, needing the problem of solution with regard to becoming those skilled in the art badly.
Utility model content
The purpose of this utility model is to overcome above deficiency, provides a kind of convenient setting, and not fragile in transport process, actv. ensures the elevator machinery arm support safe inhibiting device that elevator machinery jib maximum elevation and minimum operating angle safe spacing control.
The purpose of this utility model is achieved through the following technical solutions: a kind of supporting leg dish device for portal crane, supporting leg dish device is positioned at the below of supporting leg, supporting leg dish device comprises equalizing bar, first supporting leg dish and the second supporting leg dish, Vertical Cylinders is connected with in equalizing bar upper end, equalizing bar is provided with draw-in groove, stop gear and stop gear retracting device, Vertical Cylinders and equalizing bar bulb hinged, bulb is provided with in one end of equalizing bar lower surface, the other end is provided with axle sleeve, equalizing bar is connected with the first supporting leg dish by bulb, there is the second supporting leg dish the bottom of the other end by axle sleeve and the first hinge, equalizing bar comprises the lower cover of straight upper cover plate and V-shape structure, side plate vertical is with it provided with between upper cover plate and lower cover, distance in the middle of two blocks of side plates is greater than the spacing at two ends, U block is comprised at stop gear, T-shaped bar and the second bearing pin, U block welding is on supporting leg, T-shaped bar is connected with U block by the second bearing pin, stop gear retracting device is U plate, U plate to be welded on supporting leg and with pin hole, tell the top that U plate is positioned at U block.
The utility model compared with prior art has the following advantages: on pressure-bearing ground out-of-level or exist among a small circle difference of height also can work well, the single leg disc of effective reduction by force intensity and ground pressure-bearing, improve the stability of leg disc work.
accompanying drawing illustrates:
