Abstract
A large tonnage hoist device utilizing cross-core hoisting jack as power belongs to the hoist equipment. The hoist device comprises a main girder, the main girder is connected with a frame, an upper walking beam and a lower walking beam are separately positioned on the upper side lower side of the main girder, the cross-core hoisting jack is connected with a main force-bearing screw rod, the main force-bearing screw rod is provided with a main force-bearing screw cap, a secondary force-bearing screw rod is provided with a secondary force-bearing screw cap, the main force-bearing screw rod and the secondary force-bearing screw rod are connected with the upper walking beam and the lower walking beam through the main girder, and the lower walking beam is connected with work pieces through a force transmission screw rod. The utility model utilizes the cross-core hoisting jack as the power, adopts the structure of coordination of the cross-core hoisting jack and the screw rod group, the hoisting work for large tonnage work pieces can be completed without the need to equip the pulley group and with small field limitation, thereby improving the hoisting height.
Description
Technical field
The utility model relates to a kind of weight-lifting equipment, particularly a kind of large-tonnage hoisting device that utilizes the feedthrough jack to be used as power.
Background technology
Large-tonnage weight-lifting equipment commonly used has the supporting hoisting device of winch assembly pulley.This device keystone configuration is winch, assembly pulley and supporting system.Principle is to utilize the laborsaving principle of assembly pulley to improve the lifting tonnage.Lifting tonnage that this device improves is limited, generally can only reach 100 tons to 200 tons, and for satisfying the working space requirement of assembly pulley, the hoisting height that needs is bigger, is not suitable for hanging stenosis such as high conditional gate pier and carries out hoisting operation.
Summary of the invention
The purpose of this utility model is to provide a kind of lifting to surpass 200 tons, the large-tonnage hoisting device that utilizes the feedthrough jack to be used as power that hoisting height is big.
The purpose of this utility model is achieved in that a kind of large-tonnage hoisting device that utilizes the feedthrough jack to be used as power, comprise main bearing beam 1, main bearing beam 1 is connected with support 2, last walking beam 9 and following walking beam 12 lay respectively at main bearing beam 1 above and below, feedthrough jack 3 is connected with main stress screw rod 5, main stress screw rod 5 is provided with main stress nut 4, inferior stressed screw rod 6 is provided with time stressed nut 7, main stress screw rod 5 passes main bearing beam 1 with time stressed screw rod 6 and is connected with following walking beam 12 with last walking beam 9, and following walking beam 12 is connected with workpiece 13 by power transmission screw rod 8.Be provided with rolling bar 11 between last walking beam 9 and the main bearing beam 1.Main bearing beam 1 is provided with the equipment 10 that makes the workpiece parallel motion.The equipment 10 that makes the workpiece parallel motion can be bottle gouard moved by hands or winch or level jack.
The large-tonnage hoisting device that utilizes the feedthrough jack to be used as power provided by the utility model, the structure that adopts the feedthrough jack to cooperate with the screw rod faciation, do not need the lifting work that assembly pulley just can be finished the large-tonnage workpiece is set, be subjected to the place restriction little, improved hoisting height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done a step explanation.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Rising principle of work of the present utility model is as follows:
With workpiece 13 clamp put in place after, 3 jackings of feedthrough jack, at this moment, inferior stressed screw rod of both sides 6 and time stressed nut 7 do not stress;
Because time stressed nut 7 does not stress, the artificial suitable position of time stressed nut 7 to of rotating;
Rotate main stress nut 4 to one correct positions;
3 jackings of feedthrough jack can realize the another rising of taking turns.So circulation can rise to assigned position with workpiece 13.
The principle of work that the utility model descends is as follows:
When the stressed nut of time stressed screw rod 6 times 7 is stressed in both sides, rotate main stress nut 4, suppose that feedthrough jack stroke is 20cm away from feedthrough jack 3 plane of action 19cm.
With the very heavy jacking 19cm of feedthrough, this moment main stress nut 4 and jack 3 closed contacts, main stress screw rod 5, main stress nut 4, jack 3 is stressed, inferior stressed screw rod 6 and time stressed nut 7 do not stress.
Rotate time stressed nut 7, make it the 18cm that rises.
With jack 3 decline 18cm, this moment, time stressed nut 7 touched locking place of walking beam 9, and member is stuck.
Continue decline jack 30.5cm, this moment, main stress screw rod 5 main stress nuts 4 jacks 3 did not stress, and 6 stressed nuts 7 of inferior stressed screw rod bear total weight, promptly realize once circulation.
Can circulate according to last method next time.
The equipment 10 that makes the workpiece parallel motion can be bottle gouard moved by hands or winch or level jack, by the equipment 10 that makes the workpiece parallel motion can realize lifting or descend after the parallel motion of workpiece 13.
The purpose that rolling bar 11 is provided with is to reduce to go up friction force between walking beam 9 and the main bearing beam 1, is convenient to realize parallel motion.
