Abstract
A shifting fork type continuous reheating furnace transmission mechanism includes a bench, a shifting fork wheels group and a transmission mechanism. The bench is arranged penetrating in a heating furnace. The shifting fork wheels group consists of several shifting fork wheels, which are respectively arranged on the bench. Every shifting fork wheel is equipped with a shifting fork. The transmission mechanism is linked with the shifting fork wheels of the shifting fork wheels group. The transmission mechanism includes a motor, several transmission wheels and transitional wheels. The transmission wheels and the shifting fork wheels are coaxial fixed. The gears of the transitional wheels match the gears of the transmission wheels. The transmission wheels are driven by the motor. The bench is arranged inclined to ensure rollers to be capable of rolling downward freely. The shifting forks of the shifting fork wheels are cross-structured. The motor drives the shifting fork wheels group to roll with 90 degree each time. Every preheating roller relatively rolls forward with a workstation to finish a stepping cycle. The utility model is characterized in that the transmission mechanism has the advantages of simple and useful performances, simple and convenient maintenance and low cost and high quality, which is especially applied to the continuously rolling working condition of rollers.
Description
Technical field
The utility model relates to a kind of continuous furnace, the particularly improvement of the connecting gear of blank in the heating furnace.
Background technology
In metallurgy industry, adopt step-by-step system in the operations such as steel rolling zone blank heating stove, continuous casting zone circle, square billet air cooling field, be the stepping beam type transmission mechanism, form that its version mainly contains: eccentric earn, lever roller-type and surface rail formula by lowering or hoisting gear and board migration device.The step cycle cycle is finished by four actions, is respectively: blank rises, blank advances, blank descends and step rate retreats, and each step cycle cycle makes blank advance or a slow astern station to discharge end from charging end.As shown in Figure 1, be example with the lever roller-type, lifting hydraulic cylinder 80 makes lever 50 actions by connecting rod 60, and walking beam 30 is raised; Blank 10 originally was placed on the built-in beam 20, and when walking beam 30 was lifted to equal with blank 10 lower surfaces and continue to raise, walking beam 30 left built-in beam 20 with blank 10 picking-ups.Start advance and retreat hydraulic cylinder 40, make the stepping sill bolt blank 10 segment distance that advances on roller 70, hydraulic cylinder 40 actions stop to advance and retreat; Start lifting hydraulic cylinder 80, walking beam 30 is descended, at this moment blank 10 drops on the built-in beam 20; Restart advance and retreat hydraulic cylinder 40, walking beam 30 is regained.At this moment, walking machinery is finished a step cycle cycle, and is identical before mutual alignments such as lever, walking beam, built-in beam and the action, and the blank station that advanced.
The transmission mechanism of said structure, plant equipment is huge, and hydraulic test is safeguarded and the maintenance complexity, the cost height, area is big.
Adopt jet for gas that the roller on the open type turntable is heated in addition, so not only pollute working environment, also be difficult to control pre-heating temperature elevation speed and insulation precision, and roller surfaces often adheres to one deck carbon black after the preheating, has had a strong impact on the follow-up built-up welding repairing quality of roller.
Also there is stove to adopt the bell furnace structure, bonnet must be sling when changing roller, can not continuous operation, be difficult to satisfy the instructions for use of high load capacity workload.
Summary of the invention
The purpose of this utility model is to provide a kind of heating furnace that adopts the shift fork kind of drive, has not only guaranteed good built-up welding pre-heating technique, but also has guaranteed roller of each stepping transmission, has realized continuous production.
For achieving the above object, technical solution of the present utility model is: fork type continuous furnace connecting gear comprises stand, shift fork wheels, transmission mechanism; Described stand is arranged in the heating furnace body; The shift fork wheels are made up of several forked plectrum wheels, are arranged at respectively on the stand, and forked plectrum wheel is provided with shift fork; Forked plectrum wheel in transmission mechanism and the shift fork wheels links.
Further, described transmission mechanism comprises motor, several drives and transition wheel; This drive is coaxial fixing with forked plectrum wheel, and transition wheel cooperates with the drive gear, and drive is by motor-driven.
Again, drive is that linked transmission cooperates with motor in the described transmission mechanism.
Described stand guarantees that for being obliquely installed roller can freely roll downwards.
The shift fork of described forked plectrum wheel is cross structure.
The stepping mechanism transmission principle is: each 90 degree that rotate of motor drives shift fork wheels, this moment, former that root shifting fork bar vertically upward forwarded horizontal level to, furnace rolls loses forked plectrum wheel to be stopped and freely rolls down, former level that root shifting fork bar to the right changes into the upright position thereupon simultaneously, the auxiliary roller location that promotes roller rolled and roll down for last station.Like this, every furnace rolls station that all correspondingly rolled forward, the roller nearest from fire door promptly leaves body of heater, rolls into discharge pedestal, finishes a step cycle.
Advantage of the present utility model is that the fork type transmission mechanism is simply effective, and maintenance is simple, convenient, good and cheap, is specially adapted to the operating mode of the continuous transmission of roller class.

The specific embodiment
As Fig. 2, Fig. 3, shown in Figure 4, fork type continuous furnace connecting gear provided by the utility model comprises stand 1, shift fork wheels 2, transmission mechanism 3; Described stand 1 is arranged in the heating furnace body 5; Shift fork wheels 2 are made up of several forked plectrum wheels 21,22, are arranged at respectively on the stand 1, and stand 1 is for being obliquely installed; 2 forked plectrum wheel 21,22 links in transmission mechanism 3 and the shift fork wheels, and this transmission mechanism 3 comprises motor 31, several drives 32 and transition wheel 33; Drive 32 is coaxial fixing with forked plectrum wheel 21,22, and transition wheel 33 cooperates with drive 32 gears, and drive 32 is driven by motor 31; Described forked plectrum wheel 21 is provided with the shift fork 221 that branch is 90 °, is cross structure, and electric reducer links to each other synchronously with gear, and forked plectrum wheel in the stove is carried out 90 ° of/time rotations.
Heating furnace body 5 tops are provided with the bell 51 that is driven by motor 6, and one side opening place is provided with fire door 52; Heating furnace body 5 upper and lowers are provided with electric heating coupling 7 and heating tube 8 respectively;
Charging is carried out separately, when treating in the stove that preheat roll 4 all advances on stand 1 loading bay, starts charging forked plectrum wheel 21,22, makes it to rotate 90 degree, treats that correspondingly preheat roll 4 freely rolls down, and rolls into body of heater 5 inside and heat-treats.
Motor 31 drives transmission shift fork wheels 2 each 90 degree that rotate, this moment, former that root shifting fork bar vertically upward forwarded horizontal level to, treat that preheat roll 4 loses forked plectrum wheel 21,22 and stops and freely roll down, former level that root shifting fork bar to the right changes into the upright position thereupon simultaneously, the auxiliary roller location that promotes roller rolled and roll down for last station.Like this, treat preheat roll 4 station that all correspondingly rolled forward for every, promptly leave body of heater 5, roll into discharge pedestal, finish a step cycle from fire door 52 nearest rollers.
Again, drive can also cooperate for linked transmission with motor in the described transmission mechanism, promptly drives each drive by driving-chain and rotates.
