The utility model discloses utilizing the hoist and mount of chain block realization overhead traveling crane and translation car wheel, having reduced overhead traveling crane and fork truck's use amount, not only effectively avoided work holdup phenomenon, improved wheel maintenance work efficiency, have the running cost in addition and hang down, convenient operation, ann congruent advantage are suitable for very much and use when the wheel shaft of dismouting translation car and overhead traveling crane.
Description
Technical field
The utility model relates to a kind of fixed type lifting portal frame of the wheel hub for dismounting Horizontal shifting platform and overhead traveling crane, belongs to Slung-Load device technique field.
Background technology
Cold-rolling thin plate factory process raw material and product be all coil of strip, the transport of product in factory building can only rely on across Horizontal shifting platform and overhead traveling crane.Because overhead traveling crane and Horizontal shifting platform use frequent, wheel rim wearing and tearing are very fast, and therefore the maintenance load of wheel is very large, and dismounting wheel hub is the important content of Wheel maintenance work.
At present, the wheel hub of overhead traveling crane and Horizontal shifting platform is mostly undertaken dismantling and assembling by compression machine, because the weight of wheel and wheel shaft is all larger, manpower cannot be moved, therefore also need during maintenance to use overhead traveling crane or fork truck to carry out having bad luck and lifting, concrete grammar is: with production overhead traveling crane or fork truck, the used car of wearing and tearing wheel and spare part are lifted into Wheel maintenance place, then to sling wheel with overhead traveling crane, and be placed in the wheel hold down groove of compression machine, actuating pressure machine, old wheel hub is ejected, overhead traveling crane hangs away used car wheel afterwards, again new wheel is hung in the wheel hold down groove of compression machine, then to sling wheel hub, make it to be positioned at sustained height with wheel center line, compression machine is task again, wheel shaft is headed in new wheel, finally hang out with overhead traveling crane.The method of this dismounting wheel hub too relies on overhead traveling crane or fork truck, because overhead traveling crane is busy with one's work, causes the maintenance of wheel often to occur work holdup phenomenon, greatly reduces maintenance work efficiency; And the inconvenient drawback of revolution when using fork truck to have bad luck parts, can be there is because of narrow space in workshop, parts easily drop, and then cause safety misadventure, and the use cost of fork truck is also higher.Therefore, how to ensure the safety of Wheel maintenance, improve maintenance work efficiency, reduce maintenance cost, just become the difficult problem that relevant technologies personnel face.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of fixed type to lift portal frame, to improve Wheel maintenance work efficiency, reduces maintenance cost, eliminates safe hidden trouble.
Problem described in the utility model realizes with following technical proposals:
A kind of fixed type lifting portal frame, formation comprises two ends and is provided with the crossbeam of trapezoidal supporting leg, hung moving dolly, chain block and hydraulic press, and described hung moving dolly hangs on the trolley track on crossbeam, and its underpart is provided with hanger; Described chain block is hung on the hanger of hung moving dolly bottom, and described hydraulic press is provided with the wheel hold down groove matched with the wheel of overhead traveling crane and Horizontal shifting platform, and described wheel hold down groove is arranged on the trapezoidal supporting leg lower end inside of crossbeam one end.
Above-mentioned fixed type lifting portal frame, described hung moving dolly arranges two, and the bottom of every platform hung moving dolly is equipped with chain block.
Above-mentioned fixed type lifting portal frame, described crossbeam adopts H profile steel.
The present invention utilizes chain block to realize the lifting of overhead traveling crane and Horizontal shifting platform wheel, decrease the use amount of overhead traveling crane and fork truck, not only effectively prevent work holdup phenomenon, improve Wheel maintenance work efficiency, and it is low to have operating cost, the advantage such as easy to operate, safe, is particularly suitable for using when the wheel hub of dismounting Horizontal shifting platform and overhead traveling crane.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the birds-eye view of Fig. 1;
Fig. 4 is using state schematic diagram of the present utility model.
In figure, mark is as follows: 1, trapezoidal supporting leg; 2, crossbeam; 3, hung moving dolly; 4, wheel hold down groove; 5, chain block; 6, wheel; 7, wheel hub.
Detailed description of the invention
Referring to Fig. 1 ~ Fig. 4, the utility model comprises H profile steel crossbeam 2, trapezoidal supporting leg 1 and hung moving dolly 3 and 500T hydraulic pressure locomotive wheel hold down groove 4.
Using method (see Fig. 4): top H profile steel crossbeam 2 being arranged on two trapezoidal supporting legs 1, ensure cross beam water Pingdu≤2/1000, two hung moving dollies 3 are installed on H profile steel crossbeam 2, and a hanger is installed in each travelling car 3 bottom.500T hydraulic press (containing wheel hold down groove 4) is installed at the trapezoidal supporting leg place of crossbeam 2 side.
Overhead traveling crane continues production work by getting back to manufacturing line after used car wheel, spare part handling to Wheel maintenance place, two chain blocks 5 are suspended on the hanger of two travelling cars 3 respectively, loosen the hoisting chain of Article 1 chain block, wheel 6 has been fastened with steel rope, be suspended to lifting to hook, promote hoisting chain until hang object height in wheel hold down groove about 15cm, above movable suspending type travelling car 3 to wheel hold down groove 4, loosen hoisting chain, swivel wheel angle, makes it fall in wheel hold down groove.Hydraulic press works, old wheel hub is ejected, chain block hangs away used car wheel afterwards, again new wheel is hung in compression machine wheel hold down groove, then to sling wheel hub 7 with the chain block 5 on second hung moving dolly 3, and make it to be in sustained height with wheel center line, compression machine is task again, is pressed into by wheel shaft in the axis hole of new wheel.The wheel spare part assembled finally is hung out with chain block.
The utility model decreases wheel shaft dismounting to the constraint of overhead traveling crane and fork truck and dependence, decrease the time waiting for overhead traveling crane, improve work efficiency, save the operating costs of the mechanical implement such as crane, fork truck, reduce maintenance cost, eliminate the potential safety hazard that object drops.
