Description

Device for preventing coil falling of coil unloading vehicle

Technical Field

The utility model relates to a steel production technical field, especially a device that prevents to unload roll car and fall to roll up.

Background

In a cold-rolled sheet strip steel continuous production line, the coil falling of transportation equipment such as coil conveying vehicles, walking beams and the like is a very common fault accident. Once roll-off accidents happen, equipment damage or personnel injury is inevitably caused, and great loss is brought to production and management.

The coil unloading vehicle is one of coil conveying vehicles of a steel coil, and a coil unloading transportation control system is an open-loop control system, only controls the transverse movement of the coil unloading vehicle, cannot monitor the moving condition of the steel coil, breaks down when a mandrel of a coiling machine, and has the problems of strip steel strip head wrinkles and the like, so that the coil unloading vehicle can unload the coil and the steel coil synchronously run in the process of conveying the steel coil, and the coil is dropped.

SUMMERY OF THE UTILITY MODEL

The technical task of the utility model is not enough to above prior art, provide a prevent to unload the device that the coil former fell to roll up, through increase a coil of strip removal detection device in export coil former transportation system, feedback coil of strip moving distance is for unloading a roll transportation control system, and the transportation control system upgrades the open-loop coil former that unloads for closed loop coil former that unloads, solves export coil former transportation and rolls up the in-process and fall a roll problem.

The technical proposal of the utility model for solving the technical problem is that: the utility model provides a prevent to unload device that roll car fell to roll which characterized in that: the device comprises a mounting bracket, a range finder and a programmable controller; the range finder is in data connection with the programmable controller.

The range finder is a diffuse reflection type laser range finder.

The range finder is externally provided with a protective cover.

The range finder is in data connection with the PLC through a cable.

Compared with the prior art, the utility model discloses following outstanding beneficial effect has:

1. the utility model can monitor the moving distance of the steel coil in real time, feed the moving distance of the steel coil back to the coil unloading transportation control system, upgrade the open-loop coil unloading transportation control system into the closed-loop coil unloading transportation control system, and prevent coil falling;

2. the accident probability of production line halt caused by coil falling is reduced, and the working safety and the working efficiency are improved; 3. simple structure, light weight, low manufacturing cost, low later maintenance cost and good applicability.

Detailed Description

The invention is further described with reference to the drawings and the detailed description. In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the claimed embodiments. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

In the following embodiments, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning permanently connected, removably connected, or integral to one another; the connection can be mechanical connection, electrical connection or communication; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the embodiments of the present invention can be understood by those skilled in the art according to specific situations.

It is to be understood that the terms "central," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," "end," "side," and the like are used in an illustrative and non-restrictive sense, and are used in a generic and descriptive sense only and not for purposes of limitation, the referenced devices or elements must be in a particular orientation, configuration or operation, and not for purposes of limitation, as the orientation or positional relationship is illustrated in the figures.

As shown in fig. 1 and 2, the utility model comprises a mounting bracket 1, a distance measuring instrument 2 and a Programmable Logic Controller (PLC).

The mounting bracket 1 will the utility model discloses install in the 4 outsides of saddle.

The distance measuring instrument 2 is a diffuse reflection type laser distance measuring instrument, and laser irradiates one side of the steel coil 5. And a protective cover 3 is arranged outside the distance measuring instrument 2.

The distance measuring instrument 2 is in data connection with the PLC through a cable, and the PLC can realize logic operation and process control through other wireless modes. And the PLC is in data connection with the existing coil stripping transportation system. In addition, the PLC may also be in an existing coil-unloading transportation system.

In the optimization scheme, PLC adopts two-layer structure inside and outside the design for guaranteeing system stability in this embodiment, manages control system and peripheral system respectively: the peripheral system is remote I/O (input/output), is used as field equipment and is in data connection with the distance meter 2 to receive and collect data of the distance meter 2, and the control system is positioned in a control center and is a controller, such as a Siemens S7-1516 PLC. The controller and the remote I/O and the controller and the transmission equipment are in data communication through Profinet. In order to ensure the communication quality, the design adopts the form of an optical fiber ring network.

When the device is used, the distance meter 2 detects the moving distance of the steel coil and feeds the moving distance back to the PLC, the PLC accesses the data into the coil unloading transportation system data, and the open-loop coil unloading transportation control system (shown in figure 2) is upgraded to the closed-loop coil unloading transportation control system (shown in figure 3) to realize the closed-loop coil unloading transportation control system.

It should be noted that the software selection in the present embodiment is determined according to the corresponding hardware model, and is selected based on the capability of implementing the above functions, which belongs to the technology known in the art, and the specific structure thereof is not described again. Others, not described in detail, are well known in the art.
