Description
Technical field
The present invention relates to a kind of lowering or hoisting gear, a kind of annular furnace lowering or hoisting gear, belongs to ring-oven technique field specifically.
Background technology
Annular furnace is by furnace bottom transmission device, makes to be placed on the pipe on furnace bottom, is moved to the higher stove of mechanization degree of discharging opening in stove by charging door.
Easily there is wearing and tearing and fatigue stress in the lowering or hoisting gear of traditional annular furnace, service life is lower in long-term use, increased and safeguarded the cost of changing.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby a kind of annular furnace lowering or hoisting gear is provided, reliable in structure, is used and stablizes, and has improved service life, has reduced cost.
According to technical scheme provided by the invention, annular furnace lowering or hoisting gear comprises hydraulic cylinder seat, it is characterized in that: fixer cylinder pressure on hydraulic cylinder seat, and the piston rod front end of hydraulic cylinder connects push rod; Push rod front end connects pusher arms by bearing pin, and pusher arms front end connects back shaft; Pusher arms left and right portion connecting axle bearing, bearing block is fixed on bearing block base; Two ends, pusher arms left and right connect respectively swing arm.
Further, connect two locking nuts on back shaft, two locking nuts are positioned at pusher arms both sides.
Further, swing arm front end connects roller by roller shaft.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, and stress balance, reliable and stable in use procedure, has in use reduced wearing and tearing and fatigue stress, has improved service life, has reduced cost.

Fig. 2 is side view of the present invention.
Description of reference numerals: 1-hydraulic cylinder seat, 2-bearing block base, 3-hydraulic cylinder, 4-push rod, 5-pusher arms, 6-back shaft, 7-locking nut, 8-bearing block, 9-swing arm, 10-roller.
Detailed description of the invention
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises hydraulic cylinder seat 1, fixer cylinder pressure 3 on hydraulic cylinder seat 1, and the piston rod front end of hydraulic cylinder 3 connects push rod 4. Push rod 4 front ends connect pusher arms 5 by bearing pin, and pusher arms 5 front ends connect back shaft 6.
Pusher arms 5 left and right portion connecting axle bearings 8, bearing block 8 is fixed on bearing block base 2. Pusher arms 5 two ends, left and right connect respectively swing arm 9, and swing arm 9 front ends connect roller 10 by roller shaft.
On described back shaft 6, connect 7, two locking nuts 7 of two locking nuts and be positioned at pusher arms 5 both sides.
Operation principle of the present invention is: in the time of work, hydraulic cylinder promotes pusher arms by push rod and rotates. Pusher arms drives again back shaft to rotate, and back shaft rotates and drives the swing arm at two ends to swing.
The present invention is simple in structure, compact, reasonable, and stress balance, reliable and stable in use procedure, has in use reduced wearing and tearing and fatigue stress, has improved service life, has reduced cost.
