AI Technical Summary
During the lifting process, the steel coil may be overturned due to damage to the encoder or abnormality, causing the steel coil to fall, equipment damage and unit shutdown.
An anti-overflow device is designed, including a fixing frame and a proximity sensor on the body of the rolling car. The sensor is electrically connected to the lifting platform. When the lifting platform is detected to rise to a limiting height, the power is cut off to prevent further rise.
By detecting and power off, the lifting platform of the rolling car is prevented from falling over due to failure, avoiding steel coils falling and equipment damage, and ensuring the normal operation of the unit.

Abstract
Description
Technical Field
[0001] The present application relates to the field of steel coil processing equipment, and in particular to an anti-overshooting device used for a coil loading trolley. Background Art
[0002] The coil-up trolley is used to transport the steel coil to the uncoiling machine. In the actual production process, some unexpected situations often occur, causing equipment damage and unit shutdown. The height adjustment system of the coil-up trolley has such a hidden danger. When the up / down encoder is damaged or abnormal, the steel coil will be pushed over the head, causing the steel coil to fall, damage the equipment, and shut down the unit. Utility Model Content
[0003] In order to overcome the deficiencies of the prior art, the present application provides an anti-overthrow device applied to a winding trolley.
[0004] The present application provides an anti-overthrow device for a winding trolley, which adopts the following technical solution:
[0005] A device for preventing over-pushing applied to a winding trolley is fixedly arranged on the body of the winding trolley, the body is provided with a lifting platform, the body is provided with a fixing frame, the fixing frame is provided with a proximity sensor, the proximity sensor is electrically connected to the lifting platform, and the lifting platform is provided with an induction head cooperating with the proximity sensor.
[0006] A further technical solution is that a slider is slidably arranged on the fixing frame, and the proximity sensor is fixedly arranged on the slider; and a positioning mechanism for fixing is arranged on the slider.
[0007] A further technical solution is that the positioning mechanism includes a screw, a sliding hole is provided on the fixing frame, and the screw passes through the sliding hole and is threadedly connected to the sliding block.
[0008] This application has the following beneficial technical effects:
[0009] By arranging a fixing frame and a proximity sensor on the body of the upper winding trolley, the rising height of the lifting platform on the upper winding trolley can be detected. The proximity sensor is electrically connected to the lifting platform. When it is detected that the lifting platform has risen to the restricted height, the power of the lifting platform can be cut off to prevent the lifting platform of the upper winding trolley from tipping over and causing losses due to a malfunction. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The technical solution in this application is further described in detail below in conjunction with the accompanying drawings.
[0013] The present application discloses an anti-overshooting device for a winding trolley. Figure 1 The device is fixedly mounted on the body 1 of the upper winding trolley, and a lifting platform 2 is mounted on the body 1. The device comprises a fixing frame 3 fixedly mounted on the body 1, a proximity sensor 4 is mounted on the fixing frame 3, the proximity sensor 4 is electrically connected to the lifting platform 2, and a sensing head 5 cooperating with the proximity sensor 4 is mounted on the lifting platform 2.
[0014] The lifting platform 2 is used to place the steel coil and adjust the height of the steel coil so that the steel coil can be placed on the uncoiler for subsequent processes. One end of the fixing frame 3 is fixed on the vehicle body 1, and the other end is facing upward so that the fixing frame 3 is perpendicular to the ground. The proximity sensor 4 can be a Hall sensor, and the induction head 5 is a metal sheet attached to the lifting platform 2. When the lifting platform 2 rises to a point where the Hall sensor can detect the induction head 5, the Hall sensor controls the lifting platform 2 to disconnect from the power supply to prevent the lifting platform 2 from continuing to rise.
[0015] Furthermore, a slider 6 is slidably arranged on the fixing frame 3, and the proximity sensor 4 is fixedly arranged on the slider 6; a positioning mechanism for fixing is arranged on the slider 6. The positioning mechanism may be a screw 61, and a sliding hole 31 is provided on the fixing frame 3, the width of the sliding hole 31 is slightly smaller than the diameter of the screw 61, the screw 61 can move in the sliding hole 31, and the screw 61 passes through the sliding hole 31 and is threadedly connected to the slider 6.
[0016] The proximity sensor 4 is slidably arranged on the fixing frame 3 through the slider 6. The user can adjust the proximity sensor 4 to the corresponding height according to the different heights of the uncoiler to prevent the lifting platform 2 from being powered off and stopped when it does not reach the accurate height. After the height of the proximity sensor 4 is determined, the screw 61 can be rotated, and the nut of the screw 61 and the slider 6 are respectively pressed on the two sides of the fixing frame 3, thereby fixing the slider 6.
[0017] It should be noted that in the present invention, unless otherwise clearly specified and limited, the terms "connection", "setting", etc. should be understood in a broad sense. For example, "setting" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0018] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
