Description

Smelting furnace charging vehicle

Technical Field

The utility model relates to a metal hot working equipment field especially relates to a smelting furnace charging car.

Background

The existing smelting furnace charging trolley consists of a hopper and a push plate, after the hopper is fed into a furnace body, when the hopper slowly withdraws, the push plate needs to be pushed to push out the material, and in order to ensure that the material is uniformly pushed into the furnace body, multiple times of circulating operation are needed to push the material into the furnace body.

Because the push plate repeats the pushing and retracting process for a plurality of times, when the push plate is pushed forwards, a small amount of materials can leak from the bottom of the push plate because the bottom of the hopper cannot be completely flat. When the push plate returns, the part of the material can be pushed to the left side to be accumulated, and after the push plate is used for a period of time, some materials can be accumulated behind the push plate and need to be cleaned manually;

in the unloading process, the hopper needs to be operated for a plurality of times to withdraw and the push plate needs to stretch out, so that the materials can be uniformly added into the furnace, the operation requirement is high, and the efficiency is low.

Preferably, the skip car base is provided with rollers. The roller rolls along a specific track to drive the charging car of the smelting furnace to transport materials back and forth along a specified route.

Preferably, the push plate is arranged obliquely.

The utility model has the advantages that: (1) after a push plate of the charging trolley of the smelting furnace extends to a position, the material is completely pushed out, and the push plate is lifted and then returns. The materials leaking from the hopper can not be pushed back to the left side of the hopper. When the push plate retracts to the right position, the push plate descends to normally push materials. The improvement ensures that materials cannot be accumulated behind the push plate, reduces the labor and improves the cleanliness of the equipment; (2) the cylinder diameter/rod diameter of the hopper cylinder and the rod diameter of the push plate cylinder are completely the same, the two cylinders can be linked, hydraulic oil discharged from a rodless cavity of the hopper cylinder enters a rodless cavity of the push plate cylinder, the cylinder diameters of the two cylinders are completely the same, the speeds of the two cylinders are also the same, during linkage, the push plate is static in space, the hopper continuously retracts, materials are uniformly added into the furnace, manual control over the cooperation of the advancing progress of the push plate and the retreating progress of the hopper is not needed, and the operation is simple and efficient.

Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example (b): as shown in attached drawings 1-6, a smelting furnace charging trolley comprises a trolley base 1, a hopper 2 and a push plate 3, a hopper moving track is arranged on the trolley base, the hopper moves back and forth along the hopper moving track, a hopper cylinder 4 is fixedly connected onto the trolley base, the hopper is fixedly connected with the output end of the hopper cylinder, a push plate cylinder 5 is hinged into the hopper, the output end of the push plate cylinder is hinged with a push plate, the push plate is arranged in the hopper, the push plate moves transversely along the hopper, swing arm wheels 6 are hinged to two sides of the top end of the push plate respectively, the swing arm wheels roll along two sides of the hopper, stoppers 7 are fixedly arranged on two sides of the hopper side walls respectively along the front end and the rear end of the corresponding push plate, the stoppers block the swing arm wheels to roll, limit stoppers 8 are respectively and fixedly arranged on the. The cylinder diameter and the rod diameter of the hopper oil cylinder and the rod diameter of the push plate oil cylinder are the same, an oil outlet at the left end of the hopper oil cylinder is communicated with an oil inlet at the left end of the push plate oil cylinder through an oil pipe, a control valve is arranged on the oil pipe, oil inlets and oil outlets at the left end and the right end of the hopper oil cylinder and the left end of the push plate oil cylinder are respectively communicated with an oil pressure system through the oil pipe, a control valve is respectively arranged on each oil pipe, and each. The skip car base is provided with the gyro wheel, and the push pedal slope sets up.

When the melting furnace charging carriage is in use, as shown in figure 1, the melting furnace charging carriage takes the animal material along the track to the front of the designated furnace 9. The hopper cylinder is started to drive the hopper part into the furnace body, as shown in figure 2. At the moment, the control valve is switched to link the hopper oil cylinder and the push plate oil cylinder, as shown in the attached figure 7, the hopper oil cylinder and the push plate oil cylinder are controlled to be started, when the hopper oil cylinder is controlled to retract slowly, the push plate oil cylinder is pushed out slowly at the same speed, the push plate is static in space, the hopper retracts continuously, materials are added into the furnace uniformly, and the operation is simple and efficient. When the material is completely pushed out, as shown in the attached figures 3 and 5, the swing arm wheel swings out leftwards after touching the right side stop block until touching the limit stop block, and due to the limit of the limit stop block, the position of the swing arm wheel is limited and lifted, so that the push plate is driven to lift upwards. The linkage is removed at this moment, the push plate retracts, the push plate can keep the push plate in the return process to be lifted, and the leaked materials in the hopper can not be pushed back to the left side of the hopper. When the push plate retracts in place, as shown in the attached drawings 1 and 4, the swing arm wheel swings out rightwards after touching the left side stop block, the position of the swing arm wheel is not limited by the limit stop block, the swing arm wheel is lifted up and lowered, the push plate is lowered, and the push plate is in a normal pushing state. Thus, the whole material pushing process is completed, and the smelting furnace charging car drives away.

The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
