Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rolling mill auxiliary device, in particular to an adjustable proximity switch mounting bracket. BACKGROUND

[0002] The rolling mill body needs to be provided with a large number of limit switches at the inlet side and the outlet side of the rolling mill, as a signal of the equipment running to the limit position, including the disengaging and closing of the upper support roller shaft end clamping plate, the disengaging and closing of the upper work roller shaft end clamping plate, the disengaging and closing of the lower support roller shaft end clamping plate, the disengaging and closing of the lower work roller shaft end clamping plate, the highest and lowest positions of the side roller changing track lifting cylinder, the highest and lowest positions of the screw, the opening and closing positions of the work roller changing lock cylinder, the opening and closing positions of the support roller changing lock cylinder, the upper balancing device to the support roller changing position, the upper balancing device to the work roller changing position, the accurate stop position of the upper roller head, the accurate stop position of the lower roller head, the roller changing position of the transmission shaft positioning cylinder, the working position of the transmission shaft positioning cylinder, and more than fifty positions.

[0003] More than forty proximity switch limit devices need to be provided on the work roller changing trolley; the trolley is opened to the position near the rolling mill, the trolley is opened to the position waiting to be hooked with the roller, the rotating track is closed and opened, the transverse trolley changing roller position at the inlet side and the outlet side, the transverse trolley changing roller deceleration position, the transverse trolley opening limit position, the transverse trolley opening deceleration position, the trolley walks to the transverse position outside the rolling mill, the trolley walks to the unhooking position, the trolley walks to the transverse position outside the rolling mill before deceleration, the upper work roller falls when the trolley pulls the roller outward, the final position when the trolley pushes the roller inward to the rolling mill, the upper work roller is lifted when the trolley pushes the roller inward to the rolling mill, the trolley pulls the roller to the intermediate position outside the rolling mill, the trolley pulls the roller to the intermediate position outside the rolling mill before deceleration, the trolley pulls the roller to the farthest position in the grinding roller room before deceleration, the trolley pulls the roller to the unhooking position in the grinding roller room after deceleration, and the trolley pulls the roller to the farthest position in the grinding roller room.

[0004] More than ten proximity switch limit devices need to be provided on the support roller changing trolley: the roller changing position, the hooking position, the hooking deceleration position, the support roller lifting deceleration position, the support roller lifting position, the unhooking position, the trolley retreats to the parking position, the roller changing hook reaches the working position, the roller changing hook retreats to the non-working position, and the like.

[0005] Since so many proximity switches need to be installed after the equipment is running, the installation position of the proximity switch is determined according to the actual position to ensure that the equipment can run safely, and the correct reaction can be made in time after reaching the corresponding position, that is, stopping when stopping and decelerating when decelerating. Two sets of equipment of the finishing mill and the roughing mill will install more than 200 proximity switch limit devices.

[0006] The existing proximity switch mounting bracket is mostly non-adjustable; for example, a rectangular iron plate bracket is made, a circular hole for mounting the proximity switch is opened on the iron plate, the iron plate is welded on the structure body, and the proximity switch is mounted on the opened hole through a lock nut. In addition, some proximity switch mounting brackets can be adjusted; for example, the hole is set as a rectangle or a cross to realize the adjustment, but the rectangle and the cross can only satisfy the adjustment in a fixed straight line range and cannot satisfy the adjustment in multiple planar direction positions in a larger space, which has great limitations.

[0007] In summary, neither the non-adjustable nor the adjustable proximity switch mounting bracket can satisfy the debugging requirements. After a large number of proximity switches are mounted, they need to be repeatedly cut off and the brackets need to be repeatedly welded during the debugging process, which is a very large workload. Such removal and change of the mounting position of the bracket cannot achieve the use effect at one time, the device needs to be moved on site to determine the final position of the proximity switch to control the in-position signal in the operation process of the device, and the final accurate positioning needs to be repeatedly adjusted, which can be completed only with a large amount of labor.
