Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-lower transverse plate, 2-cylinder, 3-jack, 4-small piston, 5-piston rod, 6-lower support column, 7-upper support column, 8-upper transverse plate, 9-cylinder support column, and 10-spring.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the large-tonnage bridge crane end beam assembly jacking device comprises a lower transverse plate 1, wherein symmetrical supporting power-assisted devices are fixedly arranged on the lower transverse plate 1, each supporting power-assisted device comprises a jack 3, and each supporting power-assisted device can support the bridge crane end beam assembly; in order to increase the supporting stability, the bottom of the jack 3 is fixedly connected with the lower supporting column 6, the lower supporting column 6 is fixedly connected with the lower transverse plate 1, the top of the jack 3 is fixedly connected with the upper supporting column 7, the upper supporting column 7 is fixedly connected with the upper transverse plate 8, the supporting area is increased by the upper transverse plate 8, and the supporting stability is higher.
As preferred structure, this embodiment will realize the jacking adjustment effect of bridge crane end beam equipment, can carry out electrical control simultaneously. Support booster unit still includes cylinder 2, 9 fixed stay cylinders 2 through the cylinder support column that sets up on diaphragm 1 down, wherein cylinder 2 includes piston rod 5, jack 3 is hydraulic jack, 3 little hydro-cylinders sliding fit little pistons 4 of jack, 3 little hydro-cylinders external fixation of jack sets up spring 10, little piston 4 is through connecting plate 11 and the spring 10 fixed connection who sets up, specifically, all set up piston rod 5 and the little exposed one end of piston 4 into the scarf and both can mutually support, thereby piston rod 5 makes little piston 4 slide from top to bottom under the spring action of spring 10 in the big hydro-cylinder with oil extrusion jack with little piston 4 scarf sliding fit, force big piston rebound, jack 3 jack-up promptly. And the wedge surface area of the piston rod 5 is required to be larger than that of the small piston 4.
The working process of the present invention will be further described below:
support bridge crane end beam equipment, adopt a set of the utility model discloses support the end beam equipment. When need upwards adjusting position with certain department of bridge crane end beam equipment, open that corresponding the utility model discloses the cylinder 2 of product, the piston rod 5 and the 4 scarf sliding fit of little piston of cylinder 2, little piston 4 extrudees downwards, jack 3 jack-ups, that a department of bridge crane end beam equipment upwards promotes promptly. When the position needs to be adjusted downwards, the stop valve of the jack 3 is operated to enable oil liquid in the jack 3 to flow back, and the jack 3 descends.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
