Description

one

The invention relates to devices for servicing rotary hearth heating furnaces.

A device for servicing heating furnaces is known, which contains a mite claw trunk associated with a drive through a rack and pinion transmission and resting on a hinge located at the end of the furnace casing. In this device, the drive is located on the trunk and moves with it, creating additional inertial forces, which leads to a limitation of the speed of the machine and its performance.

In order to eliminate these drawbacks in the proposed loading and unloading device in a heating furnace with a rotating hearth, including a tick-borne trunk, a roller holder, a rail with driving bristles to move the trunk relative to the roller holder and the trunk swing mechanism in a vertical plane, the roller holder is hollowed axles coaxially with the axis of rotation of the drive gear and are installed by them in stationary supports, and the axle gear is mounted in the hollow camshaft axles.

Such a constructive solution allows to increase the speed of advancement of the trunk and increase the productivity of the maschina.

FIG. I shows a device, a plan view; in fig. 2 - the same, side view; in fig. 3 is a section along A-A in FIG. one; on -fig. 4 is a section, but BB in FIG. one; on

FIG. 5 is a section along BB in FIG. 1 (increased).

The proposed loading and unloading machine consists of a trunk 1 with a tong clamp 2 and a clamping mechanism 3, and the trunk

1 is mounted in a roller cage 4, which has two zero pins 5, which are hingedly supported on a pillar 6.

In the hollow axles 5 on rolling bearings 7 mounted drive shaft gear

8, which engages with the rail 9, is secured with the 1st on the trunk 1. With the free end of the shaft 10, the shaft-gear 8 is connected via a coupling 11 to the drive 12 of the longitudinal movement of the trunk 1.

On the back part of the rack 6 on bearings

13 installed trunk swing mechanism 14,

pivotally connected to the roller cage 4.

On the front of the rack 6 moptirovana

a spring node 15, on which they mount the holder 4, in the slots of the case of which buffers 16 are mounted, limiting the longitudinal movement of the trunk 1.

In the rear end of the trunk 1 are located the supply 17 of energy carriers and cooling associated with pipelines 18, buttransmission and

diverting cooling and air to the actuators. To enable the installation of the transporting means 19 in the rack 6, the openings 20 are made.

When loading the maschina works as follows.

The front end of the trunk 1 swing mechanism. 14 is moved to the lower position and the workpiece 19 fed by the vehicle 19 is caught by the tong clamp 2, after which the swing mechanism 14 and the suspension 15 take the trunk to the transport position.

Next, the drive 12 of the longitudinal movement mechanism is turned on, and the trunk 1 with the workpiece 21 enters the furnace (not shown in the drawing). By swinging mechanism 14, trunk 1 is moved to the lowest position, a tong-and-hold grip 2 is opened and the workpiece is laid on under the furnace, after which trunk 1 is moved to the transport position and removed from it. Then the cycle repeats.

, The unloading machine works in the same way, the difference is only in the sequence of operation of the mechanisms.
