SU38487A1 - Device for lubricating bucket elevator guide tires - Google Patents

Description

In the existing elevator installations with inclined shafts, the forging cams, supported on guide slits, are lubricated either manually or with the help of a reservoir from which the lubricant expires under a slight pressure and. falls on the rubbed surface.

In the present invention, a lubricating pump driven by a moving elevator is used to lubricate the guide tires of the bucket elevator, for which the pump shaft is designed as a toothed rack engaging with a pinion shaft periodically turned by an elevator attached to the chains when interacting with it. with a finger fixed to the spring axis of the gear.

In FIG. 1 depicts the pitches of the bucket elevator using the proposed lubricant — side view; FIG. 2 is the same, a longitudinal section through the mine elevator; FIG. The 3-part interface of the oil line with the guide rail is a longitudinal section.

An elevator 3 (Fig. 2) is attached to the traction chains of the elevator, at the end of which, slightly protruding from the plane of the chain, is rotatably mounted.

A shaft 5, resting in bearings fixed to the walls of the shaft, is passed through the shaft 6. On this roller in the plane of the roller For inside the mine

finger 4 is rigidly fastened. Gear 2 is rigidly mounted on the end of the roller 5 protruding from the shaft (FIG. 1). A piston pump 7 is attached to the wall of the shaft, the end of the rod 8 of which is made in the form of a toothed rack / which engages with the gear 2. The pump is connected to the oil tank W with the suction oil line 9 and with the pressure 77 to the surface of the guide tire 72.

As shown in FIG. 3, the injection oil line / 7 is passed through the guide rail 72. The support cam J3 of the bucket, located immediately after the spreader 3, has a somewhat broadened surface and is provided with a cavity 14 into which lubricant flows.

The operation of the proposed fixture is as follows.

Moving along with the elevator chain, the roller runs over the finger 4 and deflects it by turning the roller 5. At the same time, the jaws 2 mounted on this roller turn and, acting on the gear 7 coupled to it, lifts the piston pump rod 8 of the piston pump, which sucks the oil of the reservoir. Upon further movement of the elevator chain, roller Za slides off the pin 4 and the latter rotates the spring fixed to the roller 3, lowering the pump piston and pressurize the oil 77 through the wire 77 into the moment 14 of the outlet cam of the bucket 13 that opens at its moment. During the further movement of the elevator, the oil is put on an even layer onto the surface of the guide tire 12 ..

The subject matter of the invention.

using an oil-inducing pump driven by a moving elevator, characterized in that the piston rod of the pump is designed as a toothed rack / engaged in gear with gear 2, periodically rotated during interactions of the strut 3 with a finger 4 springs 5 axle gear.
