Abstract
Description
Technical Field
[0001] The invention relates to the field of material hardness detection, in particular to a length position detection device for steel plates with different thicknesses and large warping degrees. Background Art
[0002] When long steel plates run on roller conveyors, their current positions need to be monitored in real time. However, since there are many types of steel plates, with thickness ranging from 4mm to 20mm and length ranging from 5000mm to 8500mm, and steel plates have varying degrees of warping, displacement sensors and encoders alone cannot accurately monitor the position of the steel plates in real time. Summary of the invention
[0003] The object of the present invention is to provide a length position detection device for steel plates with different thicknesses and large warping, comprising a cylinder, a fixed bracket, a point laser sensor, a movable bracket, a rubber wheel and an encoder.
[0004] The point laser sensor is installed on a fixed bracket.
[0005] The fixed bracket is arranged horizontally, one end of which is connected to the movable bracket, and the other end of which is connected to the piston rod of the cylinder. The fixed bracket and the movable bracket are driven downward by the piston rod of the cylinder.
[0006] One end of the movable bracket away from the fixed bracket is connected with a rubber wheel.
[0007] An encoder is installed on the rubber wheel.
[0008] When the descending rubber wheel contacts the steel plate moving on the roller line, the encoder and the rubber wheel rotate coaxially on the steel plate to collect the current position state of the steel plate and monitor the length position of the steel plate moving on the roller line.
[0009] Furthermore, one end of the fixed bracket is connected to one end of the movable bracket via a rotating shaft.
[0010] A limit block is provided between the fixed support and the movable support to limit the movement of the movable support.
[0011] Furthermore, when the point laser sensor detects that the steel plate moving on the roller line reaches the reference position, the control cylinder drives the fixed bracket downward.
[0012] Further, when the downward rubber wheel contacts the steel plate moving on the roller track, the cylinder is continued to be controlled to move downward until the limit position is reached.
[0013] Furthermore, when the rubber wheel contacts the steel plate, the rubber wheel and the encoder always fit the steel plate.
[0014] Furthermore, the detection device is located above the roller track.
[0015] The technical effect of the present invention is undoubted, and the beneficial effects of the present invention are as follows:
[0016] The device of the invention has simple structure, convenient operation and high automation, and can monitor the position of the steel plate in real time. BRIEF DESCRIPTION OF THE DRAWINGS
