Abstract

A gantry crane able to be assembled or disassembled on the ground without hoister is composed of a transverse beam, a carriage on said transverse beam, two master poles connected via cross jointers to both ends of said transverse beam, two secondary poles connected via cross jointer between transverse beam and master pole, the casters at lower ends of master poles, etc.

Description

Transfer crane

Technical field

The present invention relates to hoisting crane, particularly have the hoisting crane of the dolly of on door frame movably, walking.

Background technology

Transfer crane is made of pulling of hang connecting on institute's frame dolly, the dolly on crossbeam, pole that the crossbeam two ends join, the crossbeam or electric block etc.Existing transfer crane is owing to structural reason, and it is cumbersome to make it assembly and disassembly, and, the setting up of crossbeam upright as the support of pole all needs high-order lifting operation, also like this during dismounting, this has not only increased the work capacity of assembly and disassembly, and the equipment of employing increase, and safety is also influenced.

Desirable situation is that this lifting function is carried out assembly and disassembly on the ground, need not lifting and high-order homework, and is not only safe but also save time.

Summary of the invention

The present invention will solve existing transfer crane assembly and disassembly trouble, time-consuming, can not carry out the problem of assembly and disassembly on the ground, a kind of transfer crane of the present invention is provided for this reason, and the assembly and disassembly of this transfer crane can be carried out on the ground, need not high-order lifting operation.

For addressing the above problem, the technical solution used in the present invention be provided with crossbeam and on institute's frame dolly, the both sides at crossbeam two ends respectively are associated with a mobile jib, prop up on the mobile jib and be associated with secondary bar, secondary bar upper end is coupled to crossbeam, and the mobile jib lower end is associated with roller, and the both sides at crossbeam two ends join and are associated with bottom bar between the mobile jib bottom, its special character is: be associated with the shoulder joint on the crossbeam, mobile jib and secondary bar upper end pivot are connected with the cross joint; The both sides at described crossbeam two ends respectively are associated with a mobile jib and are meant: the cross joint pivot that described mobile jib upper end pivot connects is connected in the shoulder joint; Described secondary bar upper end is coupled to crossbeam and is meant: the cross joint pivot that described secondary bar upper end pivot connects is connected in the shoulder joint.

Being associated with shoulder joint on the described crossbeam is meant: the crossbeam two ends respectively are associated with a shoulder joint and crossbeam two ends extends a distance to the crossbeam middle part respectively and respectively is associated with a shoulder joint, and described shoulder joint is parallel to each other and an alternate distance, two shoulders that intersect with 90 ° on crossbeam save pieces and constitute by comprising; The cross joint pivot that described mobile jib upper end pivot connects is connected in the shoulder joint and is meant that this cross joint pivot is connected in the crossbeam two ends and joins between the two shoulder joint pieces of shoulder joint, and the cross joint pivot that described secondary bar upper end pivot connects is connected in the shoulder joint and is meant that this cross joint pivot is connected in the crossbeam two ends and extends two shoulders apart from place connection shoulder joint to the crossbeam middle part respectively and save between the pieces.

Be associated with shoulder joint on the described crossbeam and can be meant and be associated with connecting panel above the crossbeam, be associated with the shoulder joint on the connecting panel.

Be associated with the shoulder joint on the described crossbeam and can be meant that also cover is embedded with the shoulder joint on the crossbeam.

Described mobile jib lower end is associated with roller can be meant that the mobile jib lower end is associated with ankle and saves and be associated with roller below it.

Pivot described in the present invention even can be meant through bar axle, nut and cooperate pivot to connect.The pivot of described mobile jib, secondary bar and cross joint connects, and the cross joint connects with the pivot of shoulder joint, is to cooperate through screw shaft, nut to tighten connection.Because mobile jib has sufficient length, in opposite directions or dorsad the application of force can produce big moment in the mobile jib lower end of crossbeam one end both sides, making the cross joint and the junction of shoulder joint can locate the connecting screw rod axle according to this is that the turning cylinder generation pivots, make the mobile jib lower end of crossbeam one end both sides draw close mutually or leave, the mobile jib of crossbeam other end both sides is also like this; In fact owing to bolt, nut cooperate, it is relative tightening, promptly loosening relatively, can produce pivot when enough moment, and in this case, guarantee that structural stability of the present invention and assembly are unlikely destroyed, can accomplish.Secondary bar among the present invention is in same plane with mobile jib all the time, and this plane is meant the two mobile jibs plane of living in of the same side, crossbeam two ends.Secondary bar lower end is coupled to mobile jib, and secondary bar upper end links through cross joint and shoulder joint; When the mobile jib lower end of crossbeam one end both sides was drawn close mutually or left, secondary bar moved together in company with mobile jib, because secondary bar upper end is connected with the shoulder joint through the cross joint, its pivot situation is similar to mobile jib.Just because of can form this pivot, promptly the mobile jib lower end of crossbeam one end and other end both sides can realize drawing close mutually or leaving, so the present invention can be in ground assembling or dismounting.

Crossbeam can be placed on two pallets or the carriage during assembling, make its liftoff distance, on crossbeam, load onto the shoulder joint again, load onto the cross joint on the shoulder joint, load onto mobile jib and secondary bar on the cross joint, secondary bar lower end is connected in mobile jib, roller is loaded onto in the mobile jib lower end, because the liftoff distance of crossbeam, so the mobile jib of crossbeam one end and other end both sides has an angle and is not in a straight line, when tractive was drawn close mutually simultaneously, the mobile jib upper end promoted together with crossbeam through traction machine or Lever Blocks in two mobile jib lower ends of crossbeam one end and other end both sides, during to certain altitude, set up described bottom bar in mobile jib lower end, crossbeam both sides.Can be undertaken by reversing sense during dismounting.

In addition, the present invention can also form collapsible assembly set after dismounting, with convenient storing and assembling next time.Mobile jib is separated in secondary bar lower end, and the two mobile jib lower ends at crossbeam one side two ends can be drawn close and further draw close to crossbeam in opposite directions, and the situation of secondary bar is similar, make crossbeam, mobile jib, secondary bar constitute the folded form assembly set together.

Crossbeam among the present invention, mobile jib, secondary bar, shoulder joint, cross joint can both be dismantled one by one, become separate piece, can be correlated with one by one during assembling to cooperate and install.

The present invention is owing to be connected with the cross joint at mobile jib and secondary bar upper end pivot, the shoulder that cross joint pivot is connected on the crossbeam and is joined saves, so this bright can assembling on the ground, after the related components assembling is finished, make it to draw close mutually with the mobile jib lower end of tractive crossbeam one end and other end both sides and reach bottom bar on the requirement fashionable dress, finish assembling of the present invention and set up.Keep the crossbeam level during mobile jib tractive of both sides, crossbeam two ends,, can accomplish in order to avoid the hand cart on the crossbeam slides.Can be undertaken by reversing sense when the present invention dismantles, finish dismounting on the ground.The present invention is assembly and disassembly on the ground, need not to lift high-order homework, and is safe and convenient, save time.
