Description

Interlocking device for preventing steel from damaging lifting arm

Technical Field

The utility model particularly relates to a prevent that steel from crashing interlocking device of material arm that rises belongs to steel collection platform technical field.

Background

In the prior art, the bar processing procedures are as follows in sequence: heating, rolling, multiple length shearing, cooling, shearing, inspection, packing, measurement warehouse entry, when the rod enters into measurement warehouse entry, beat bundle and weigh the rod earlier, when the rod production line among the prior art collects steel, steel is beaten the back and is got into collection platform through the roll table transportation, lift up steel at collection platform through the lifting arm, then transport collection platform with the chain and go on reinspection weighing and hang the tablet, if next bundle of steel gets into collection platform from the bundling machine roll table under the circumstances that lifting arm did not fall down, then lift up the in-process at the lifting arm, next bundle probably hits on the lifting arm, cause the equipment accident.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a prevent that steel from crashing interlocking device of material arm, when collecting the platform material arm and rise, the roll table automatic stop is beaten at the rear, stops steel outside collecting the platform, reaches the purpose that prevents steel dress material arm, but multiple detection auto-lock avoids appearing hitting the steel accident.

The utility model discloses an interlocking device for preventing steel from crashing the material lifting arm, in the process of collecting bars, when steel is transported to enter the collecting platform, the interlocking device for preventing the material lifting swing arm from being crashed by steel to cause equipment accidents comprises a bundling roller way, a material lifting swing arm, a No. 1 chain and an interlocking device of the material lifting swing arm and the bundling roller way; when the lifting arm of the collecting platform rises, the bundling roller way automatically stops, and steel is forbidden to enter the collecting platform until the lifting arm falls down, so that the condition that the steel hits the lifting arm is avoided, and the purpose of reducing equipment accidents is achieved; when the collecting platform lifting arm is lifted, a lifting signal is fed back to the PLC, and the PLC gives a bundling machine stop signal; after the collecting platform lifting arm falls down, a bundling roller way stop signal is automatically released, and the collecting platform lifting arm has the following specific structure: the device comprises a bundling roller way and a collecting platform, wherein the collecting platform is opposite to the bundling roller way and is provided with a roller way; a collision baffle is fixed on one side of the roller way, which is far away from the bundling roller way; the material lifting swing arms are arranged in the roller way in a staggered mode, and transmission chains are arranged among the material lifting swing arms at intervals; the transmission chain arrangement position is higher than the top surface of the roller way; the material lifting swing arm and the bundling roller way driving device are both connected into a PLC, wherein the action signal of the material lifting swing arm is directly obtained through the PLC.

Further, a second proximity switch is installed outside the collection platform; the detection position of the second proximity switch is over against the lowest position of the material lifting swing arm; the second proximity switch is connected to the PLC, when the signal of the second proximity switch is lost, the material lifting swing arm swings, and at the moment, the bundling roller way is controlled to stop acting until the second proximity switch detects the signal again.

Further, a first proximity switch is fixed on the output side of the bundling roller way; first proximity switch inserts PLC, when PLC acquires the material swing arm material lifting, at this moment, first proximity switch still detected the signal, then shows to beat and beat the control of bundle roll table inefficacy, and at this moment, PLC shuts down the processing to whole platform, and until troubleshooting back, PLC gives again and beats the power transmission of bundle roll table.

Compared with the prior art, the utility model discloses a prevent that steel from hitting interlocking device who damages the liftout arm has following advantage:

when the collecting platform lifting arm rises, the rear bundling roller way automatically stops to stop steel outside the collecting platform, so that the purpose of preventing the steel from being installed on the lifting arm is achieved, the self-locking can be detected in multiple ways, and the steel collision accident is avoided.

Detailed Description

Example 1:

as shown in fig. 1 and 2, the interlocking device for preventing a lifting arm from being damaged by steel materials, which is used for preventing the lifting arm from being damaged by steel materials when the steel materials are conveyed to a collecting platform in the bar collecting process, and causing equipment accidents, comprises a bundling roller way, a lifting arm, a 1# chain and an interlocking device of the lifting arm and the bundling roller way; when the lifting arm of the collecting platform rises, the bundling roller way automatically stops, and steel is forbidden to enter the collecting platform until the lifting arm falls down, so that the condition that the steel hits the lifting arm is avoided, and the purpose of reducing equipment accidents is achieved; when the collecting platform lifting arm is lifted, a lifting signal is fed back to the PLC, and the PLC gives a bundling machine stop signal; after the collecting platform lifting arm falls down, a bundling roller way stop signal is automatically released, and the collecting platform lifting arm has the following specific structure: the device comprises a bundling roller way 1 and a collecting platform 2, wherein the collecting platform 2 is opposite to the bundling roller way and is provided with a roller way 3; a collision baffle 4 is fixed on one side of the roller way 3 away from the bundling roller way; the material lifting swing arms 5 are arranged in the roller way 3 in a staggered mode, and transmission chains 6 are arranged among the material lifting swing arms 5 at intervals; the arrangement position of the transmission chain 6 is higher than the top surface of the roller way 3; the material lifting swing arm 5 and the driving equipment of the bundling roller way 1 are both connected into a PLC, wherein the action signal of the material lifting swing arm is directly obtained through the PLC.

Wherein, a first proximity switch 7 is fixed on the output side of the bundling roller way 1; first proximity switch 7 inserts PLC, when PLC acquires the material swing arm material lifting, at this moment, first proximity switch still detected the signal, then shows to beat and beat the control of bundle roll table inefficacy, and at this moment, PLC shuts down the processing to whole platform, and until troubleshooting back, PLC gives again and beats the power transmission of bundle roll table.
