Description
Technical Field
The utility model relates to a device for quick replacement platform truck belongs to mechanical equipment technical field.
Background
Sintering machine system in large-scale ferrous metallurgy enterprise, through convulsions sintering, sinter into the bulk through adding water, the good mixture of balling with iron-containing material, flux, fuel etc. for the blast furnace uses. The sintering machine is used as the main equipment of the sintering system, and the stable operation rate of the sintering machine directly influences the operation efficiency of the sintering system.
The trolley in the sintering machine system is a single piece of continuous operation equipment and is influenced by factors such as long-time high temperature, abrasion, uneven stress and the like, trolley wheels are easy to fall off, and the trolley falling off wheels is easy to block and influence the operation. In order to ensure the operation of the sintering machine, the trolley with wheels falling needs to be replaced, the trolley needs to be replaced by an overhead travelling crane of a sintering machine chamber, hoisting devices such as a hook of the trolley are replaced by a steel wire rope, and the trolley is hoisted by the traditional hoisting device, so that the following defects exist in the replacement process of the traditional hoisting device:
1. a single steel wire rope is stressed greatly and is easy to generate fatigue fracture;
2. each hook of the main beam and the hook needs to be hung by a single person in the using process, and 4 persons need to be hung each time, so that more persons are used;
3. because the hook is worn for wire rope alone, the quality is great, accidents such as easy production bruise.
Therefore, how to replace the trolley quickly and efficiently becomes a problem to be solved urgently for related technical personnel.
Disclosure of Invention
The utility model aims at providing a device for quick replacement platform truck through girder and hydraulic system, realizes the automatic horizontal migration who realizes the couple, and quick accurate has hung the platform truck with the couple and has rolled axle sleeve position, tightens up the couple automatically, can realize quick, high-efficient change platform truck, and the user of service is few, and is safe convenient, has solved the above-mentioned problem that exists in the background art effectively.
The technical scheme of the utility model is that: a device for quickly replacing a trolley comprises a main beam, four lifting hooks, a hydraulic system, an electrical system and a lifting system, wherein the four hooks are arranged on the main beam and are uniformly distributed on two sides below the main beam; the hydraulic system is embedded in the main beam and connected with the hook; the electric system is connected with the hydraulic system through the hydraulic push rod; the hoisting system is a steel wire rope system arranged on the main beam and is converged at the middle part.
The main beam is made of steel plates with certain strength.
And hydraulic driving blocks are arranged at two ends of the hydraulic system.
The utility model has the advantages that: through girder and hydraulic system, realize the automatic horizontal migration who realizes the couple, the quick accurate platform truck that hangs the couple well wheel axle sleeve position, automatic the tightening hook can realize quick, high-efficient change platform truck, and the user is few, and is safe convenient.

Detailed Description
In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the following will combine the drawings in the embodiment to clearly and completely describe the technical solution in the embodiment of the present invention, and obviously, the embodiment described is a small part of the embodiment of the present invention, rather than the whole embodiment, based on the embodiment of the present invention, all other embodiments obtained by the ordinary skilled person in the art without creative work belong to the protection scope of the present invention.
A device for quickly replacing a trolley comprises a main beam 2, lifting hooks 3, a hydraulic system 4, an electrical system 6 and a lifting system 7, wherein four hooks 3 are arranged on the main beam 2 and are uniformly distributed on two sides below the main beam 2; the hydraulic system 4 is embedded in the main beam 2, and the hydraulic system 4 is connected with the hook 3; the electric system 6 is connected with the hydraulic system 4 through a hydraulic push rod; the hoisting system 7 is a steel wire rope system arranged on the main beam 2 and is converged at the middle part.
The main beam 2 is made of steel plates with certain strength.
And two ends of the hydraulic system 4 are provided with hydraulic active blocks 5.
In practical application, the utility model discloses a working process as follows:
firstly, the trolleys on two sides of the trolley to be replaced are fixed by using wedges, so that the trolleys are prevented from moving.
Second step, will the utility model discloses two hydraulic push rods are opened, place on the platform truck body that needs to be changed, and couple 3 is automatic flagging.
And thirdly, stopping the vertical action of the main beam 2 when the small hooks of the hook 3 reach the two sides of the wheel shaft sleeve of the trolley, tightening the hydraulic push rod, so that the hook 3 is tightened, and the hook 3 clamps the shaft sleeve of the wheel.
And fourthly, using a crown block to connect the hoisting system 7 to hoist the trolley needing to be replaced.
And fifthly, moving the main beam 2 downwards when the trolley is placed at the standby trolley position, and opening the hydraulic push rod.
And sixthly, hoisting the new trolley into the sintering machine system in the same way.
And finally, the wedges for fixing the trolleys on the two sides are taken down, the sintering machine is powered on, the machine speed is adjusted to normally run, and the process of replacing the trolleys is completed.
