Description

Technical Field

[0001] This utility model relates to the field of metal smelting equipment technology, and in particular to a coiling device. Background Technology

[0002] In steel plants, commonly used equipment includes LF furnaces (ladle refining furnaces). When LF furnaces enter or leave the smelting area, it is necessary to wind up and unwind the overhead crane cables and cooling air ducts.

[0003] Currently, there are two common methods for cable winding and unwinding. One method uses a mechanical spring, where a trolley pulls the cable down while the spring winds up the cable and air hose. This method is simple and effective, but the spring is prone to deformation and failure, preventing the cable from rewinding properly and damaging the cable and air hose. The other method uses a torque motor to achieve cable and air hose release and rewinding. The torque between the motor and the cable is detected, and the motor's forward and reverse rotation is controlled to achieve cable and air hose winding and release. This is also an effective control method, with cable and air hose release and rewinding actively achieved through the motor's forward and reverse rotation. In actual operation, problems often arise in matching the motor speed with the trolley's travel speed. Even with a constant trolley speed and motor speed, the cable on the reel is constantly changing, often causing overwinding and over-slack, further leading to mechanical failure. Utility Model Content

[0004] This invention provides a winding device for winding and unwinding cables or pipes in a manner that matches the speed of the moving object.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A winding device is used to wind and unwind cables or pipes connected to a moving object. The winding device includes a winding motor, a winding reel, a buffer, multiple guide wheels, and a control mechanism. The buffer includes a column with a slide rail and a counterweight wheel that can move up and down within the slide rail. One end of the cable or pipe is wound around the winding reel, and the other end is connected to the moving object. The guide wheels guide the counterweight wheel to press against the cable or pipe. The winding motor is connected to the winding reel to drive the winding reel to rotate and realize the winding and unwinding of the cable or pipe. The control mechanism is connected to the winding motor to control the winding motor according to the signal fed back from the buffer.

[0006] Preferably, it also includes a detection mechanism, which is used to detect whether the counterweight wheel is in the cable release position or the winding position and to send back corresponding signals. The detection mechanism is connected to the control mechanism. When the counterweight wheel is in the cable release position, it sends a signal to the control mechanism. The control mechanism controls the winding motor to drive the winding reel to rotate, thereby releasing the cable or pipe. When the counterweight wheel is in the winding position, it sends a signal to the control mechanism. The control mechanism controls the winding motor to drive the winding reel to rotate, thereby winding the cable or pipe.

[0007] Preferably, the detection mechanism includes multiple position switches mounted on the column, which determine whether the counterweight wheel is in the cable-laying or winding position by detecting whether the counterweight wheel passes through the corresponding position switch; or it includes a height measuring element for detecting the height of the counterweight wheel, which determines whether the counterweight wheel is in the cable-laying or winding position by comparing the height of the counterweight wheel obtained in real time with a set value.

[0008] Preferably, there are multiple buffers, and each buffer has guide wheels on both sides so that the counterweight wheels of each buffer press on the cable or pipe.

[0009] Preferably, at least one buffer is provided with a detection mechanism, which is used to detect whether the counterweight wheel is in the cable release position or the winding position, and is connected to the control mechanism. When the counterweight wheel is in the cable release position, it sends a signal to the control mechanism, which controls the winding motor to drive the winding reel to rotate to release the cable or pipe. When the counterweight wheel is in the winding position, it sends a signal to the control mechanism, which controls the winding motor to drive the winding reel to rotate to wind the cable or pipe.

[0010] Preferably, the detection mechanism includes multiple position switches mounted on the column, which determine whether the counterweight wheel is in the cable-laying or winding position by detecting whether the counterweight wheel passes through the corresponding position switch; or it includes a height measuring element for detecting the height of the counterweight wheel, which determines whether the counterweight wheel is in the cable-laying or winding position by comparing the height of the counterweight wheel obtained in real time with a set value.

[0011] Preferably, the moving object is a transfer trolley for the LF furnace.

[0012] Preferably, it also includes a damping roller, which is disposed on the winding spool and is used to provide damping. Together with the counterweight roller, it ensures that the cable or pipe always maintains a certain tension.

[0013] Preferably, the damping roller is also used to disengage the winding reel when the winding force is greater than the set damping, thereby preventing overwinding.

[0014] The beneficial effects of this utility model are as follows: The winding device of this utility model, by setting up a winding motor, winding reel, buffer, multiple guide wheels, control mechanism and other components, uses the control mechanism to control the winding motor according to the signal fed back by the buffer, which can eliminate the problem of mismatch between the winding speed of the cable or pipe and the speed of the moving object, so that the winding and unwinding of the cable or pipe is matched with the speed of the moving object, and the cable and pipe will not be damaged due to overwinding or over-winding, which will affect the continuity of production.

[0015] Figure 1This is a schematic diagram of the winding device according to the first embodiment of the present invention.

[0016] Figure 2 This is a schematic diagram of the winding device according to the second embodiment of the present invention. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and examples.

[0018] Figure 1 The diagram shows a first embodiment of the winding device of this utility model. In this embodiment, the winding device is used to wind up and unwind cables or pipes 12 connected to a moving object 11 (in this embodiment, it is a transfer trolley for an LF furnace, but it can also be other moving objects).

[0019] In this embodiment, the winding device includes a winding motor 13, a winding reel 14, a buffer 15, multiple guide wheels 18, and a control mechanism (not shown). The buffer 15 includes a column 152 with a slide rail 151 and a counterweight wheel 153 that can move up and down within the slide rail 151, so that one end of the cable or pipe 12 is wound around the winding reel 14 and the other end is connected to the moving object 11, with the guide wheels 18 guiding the counterweight wheel 153 to press against the cable or pipe 12. The winding motor 13 is connected to the winding reel 14 to drive the winding reel 14 to rotate and realize the winding and unwinding of the cable or pipe 12. The control mechanism is connected to the winding motor 13 to control the winding motor 13 according to the signal fed back from the buffer 15.

[0020] The signal source for the buffer 15 can be various; in this embodiment, it is obtained by detecting the position or height of the counterweight roller 153. In this embodiment, the winding device also includes a detection mechanism, which detects whether the counterweight roller 153 is in the unwinding or winding position and sends a corresponding signal. The detection mechanism is connected to a control mechanism. When the counterweight roller 153 is in the unwinding position, it sends a signal to the control mechanism, which then controls the winding motor 13 to drive the winding reel 14 to rotate, thus releasing the cable or pipe 12. When the counterweight roller 153 is in the winding position, it sends a signal to the control mechanism, which then controls the winding motor 13 to drive the winding reel 14 to rotate, thus winding the cable or pipe 12.

[0021] Specifically, in this embodiment, the detection mechanism includes multiple position switches mounted on the column 152. It determines whether the counterweight roller 153 is in the cable-laying or winding position by detecting whether the counterweight roller 153 passes the corresponding position switch (in this case, a digital signal is fed back). The corresponding position switches can be referred to as cable-laying position switch 161 and winding position switch 162. The position switches may also include an upper limit position switch 163 and a lower limit position switch 164 to detect whether the counterweight roller 153 is in the upper limit and lower limit positions, respectively.

[0022] The detection mechanism may also include a height measuring element for detecting the height of the counterweight wheel 153. The height of the counterweight wheel 153 is measured in real time by the height measuring element (in this case, an analog signal is fed back). The relationship between the height of the counterweight wheel 153 and the set value is compared to determine whether the counterweight wheel 153 is in the cable laying position or the winding position.

[0023] In this embodiment, the winding device further includes a damping roller 17, which is disposed on the winding reel 14 to provide damping. Together with the counterweight roller 153, it ensures that the cable or pipe 12 always maintains a certain tension. Furthermore, the damping roller 17 can also be used to disengage the winding reel 14 when the winding force exceeds the set damping, thereby preventing overwinding.

[0024] like Figure 2 As shown, there can be multiple buffers (two in this second embodiment, named first buffer 25 and second buffer 35 respectively). Each buffer has guide wheels 28 on both sides so that the counterweight wheels 253 and 353 of each buffer press on the cable or pipe 22. Other structures are the same as in the first embodiment. The detection mechanism only needs to be set on one of the buffers (first buffer 25), but it can also be set on multiple buffers.

[0025] The operation method of the winding device described above includes: adjusting the weight of the counterweight roller and the damping magnitude of the damping roller according to the properties of different cables or pipes, so that the cable is in a taut state, while a certain amount of cable or pipe is buffered on the buffer; when releasing the cable, the cable on the buffer is released first to overcome the damping of the winding reel. At this time, the cable is passively released, and the power is provided by the moving object. The control mechanism starts the winding motor to actively release the cable according to the signal fed back by the buffer, and stops the winding motor according to the signal on the buffer; when winding, the control mechanism starts the winding motor according to the signal fed back by the buffer, and the damping roller disengages during overwinding to prevent overwinding and protect the cable.

[0026] Compared to existing technologies, the winding device in this embodiment efficiently winds up and unwinds cables or pipes during operation, keeping the cables or pipes aligned with the transfer trolley and maintaining a certain tension to prevent dragging on the ground. This prevents accidents caused by cables being too tight or too loose, and plays a beneficial role in ensuring the continuity of production.
