Abstract
The utility model discloses an elongated tooth bar vertical-dropping prevention device for a steel coil transportation dolly, which is used for the data detection of the encoders of an upper coiling steel coil dolly and a lower coiling steel coil dolly. The elongated tooth bar vertical-dropping prevention device mainly solves the technique problem of equipment faults caused by the data feedback error of a dolly encoder due to the sagging of the linkage tooth bars of the encoder. According to the technical scheme of the utility model, the elongated tooth bar vertical-dropping prevention device for a steel coil transportation dolly comprises a steel plate body equipped with a fixed support. The upper and lower ends of the steel plate body are equipped with a gear engaged with the upper gear of the connection shaft of an encoder, and a rolling bearing served as a tooth bar carriage. One ends of the gear and the internal diameter shaft of the rolling bearing are welded with the steel plate and the other ends of the gear and the internal diameter shaft of the rolling bearing are fixed through tumbler pins. The steel plate body is fixed to the body of a transportation dolly through fixed supports on the two sides of device by bolts. The device is mainly used for preventing the vertical dropping of elongated tooth bars served for the data detection of the encoder of a steel coil dolly.
Description
Technical field
The utility model relates to the anti-falling unit that hangs down of the microscler tooth bar of a kind of coil of strip travelling bogie, relates in particular to the anti-falling unit that hangs down of microscler tooth bar that coil volume dolly and last volume coil of strip dolly encoder data detect usefulness.
Background technology
Volume and outlet last volume all adopt dolly to transport on the cold rolling mill inlet, and the carriage walking distance is back and forth operation in 10 meters scopes.Dolly is when automatic operation, and the accuracy rate of the travel distance of dolly is particularly important, and the stop position mal can cause coil of strip to tumble and to insert the mandrel amount excessive for coil of strip, causes coil of strip and the unit line of centers can't centering, influence production.With reference to Fig. 1, the carriage walking distance-measuring device comprises that coder 9, coder coupling spindle cog 5, tooth bar 1 is formed.Dolly body 4 is seated on the trolley track 3, and tooth bar 1 is fixed on the tooth bar support 2, and tooth 5 connects coder 9 through bearing 6, coder catcher 7 on the coder coupling spindle, and dolly body 4 is provided with electrical motor 8.Dolly body 1 moves back and forth on trolley track 3 through dolly wheel under the traction of electrical motor 8, the coder coupling spindle cog 5 with tooth bar 1 engagement, change the travel displacement amount into electric signal output through coder.The built on stilts tooth bar length that is installed on the platform of level has 10 meters, owing to adopt one-sided limit bolt, and behind the long-play; Cause tooth bar to produce sag in different local sections, it is too big with the tooth bar gap that the coder coupling spindle is cogged, and can't realize engagement; Gear does not rotate, and coder does not have the output of data feedback, and detecting cumulative data can reduce; Set run-length data with former dolly and compare, dolly will not stop in this position of stopping, and can walk on; Data are the same with the former travel settings data of dolly up to detecting, and just stop.Like this, dolly is operated under the precarious position, can't carry out automatically, influences unit production.
Through retrieval, do not find in the prior art 10 meters microscler tooth bars of coder detection usefulness are prevented the sag technology.The tooth bar that uses in the specification sheets of Chinese patent CN200510025366.5 " artificial board blank thickness control device " vertically is installed on the push rod, and push rod drives the tooth bar perpendicular movement, and it is short to measure stroke distances, does not have tooth bar sag phenomenon.The mode of fixing, adjusting that its tooth bar adopts sliding pin and slide block to carry out, operation can't reliably realize following property on the microscler tooth bar that level is installed, and is prone to cause the jam phenomenon to occur.
The tooth bar that uses in the specification sheets of Chinese patent CN200720031967.1 " pipe expanding oil cylinder stroke detection control apparatus " is fixed on the installation sleeve; The tooth bar sag can not appear; Its wheel word is movable the installation, adopts spring tension gear just for eliminating the wheel and rack gap.Just the strength of gear direction is a kind of pulling force, can not effectively solve the displacement of gap up and down that gear and level are installed tooth bar.
The utility model content
The purpose of the utility model is to provide the microscler tooth bar of a kind of coil of strip travelling bogie the anti-falling unit that hangs down, and mainly solves the technical matters that coder interlock tooth bar sag causes the breakdown of equipment that dolly encoder data feedback error causes.
The technical scheme of the utility model is: the anti-falling unit that hangs down of the microscler tooth bar of a kind of coil of strip travelling bogie; Comprise that is with a support bracket fastened steel plate body, steel plate body upper and lower side install one with coder coupling spindle cog mating gear and a antifriction-bearing box as the tooth bar carriage.One end of gear and antifriction-bearing box bore axes is welded on the steel plate, and the other end is fixed with set pin.The steel plate body is fixed by bolts on the travelling bogie body through the both sides fixed support.
Gear and antifriction-bearing box on the steel plate body cogs the coder coupling spindle and tooth bar is clamped up and down through being installed in, and limits the upper and lower displacement amount that tooth bar and coder coupling spindle cog, and eliminates the wheel and rack gap, accomplishes that no gap meshes.Adopt the Support bracket of antifriction-bearing box,, avoided the sag of tooth bar to occur because vertical distance has limited as tooth bar.
The utility model beneficial effect is: limit the upper and lower displacement amount that tooth bar and coder coupling spindle cog through being installed in gear and bearing on the steel plate body, eliminate the wheel and rack gap, accomplish that no gap meshes.Adopt the Support bracket of antifriction-bearing box,, avoided the sag of tooth bar to occur because vertical distance has limited as tooth bar.The data feedback that makes coder accurately, trace performance is good.

The specific embodiment
With reference to Fig. 1,2; The anti-falling unit that hangs down of the microscler tooth bar of a kind of coil of strip travelling bogie; Comprise that is with a support bracket fastened steel plate body 13, steel plate body 13 upper and lower sides install one with coder coupling spindle cog 5 mating gear 10 and a antifriction-bearing box 11 as tooth bar 1 carriage.One end of gear 10 and antifriction-bearing box 11 bore axes is welded on the steel plate body 13, and the other end is fixing with set pin 14.Steel plate body 13 is fixed by bolts on the travelling bogie body 4 through both sides fixed support 12.
With reference to Fig. 3,4; The coder coupling spindle is cogged 5 clamp up and down through being installed in gear 10 and antifriction-bearing box 11 on the steel plate body with tooth bar 1; Limit cog 5 upper and lower displacement amount of tooth bar 1 and coder coupling spindle; Eliminate the coder coupling spindle cog 5 with tooth bar 1 gap, accomplish that no gap meshes.Adopt the Support bracket of antifriction-bearing box 11,, avoided the sag of tooth bar to occur because vertical distance has limited as tooth bar 1.Dolly body 4 moves back and forth on trolley track 3 through dolly wheel under the traction of electrical motor 8, the coder coupling spindle cog 5 with tooth bar 1 engagement, change the travel displacement amount into electric signal output through coder 9.
