[0002] In the process of using steel coils, it is common to use lifting devices to transport and lift the steel coils.

[0003] For example, the Chinese utility model with announcement number CN211569872U discloses "a convenient steel coil lifting device". During use, the device uses a crane to lift the lifting block and move it to just above the steel coil to be lifted, then loosens the fastening bolts, rotates the adjustment shaft to adjust the distance between the right hanger and the left hanger to match the width of the steel coil, tightens the fastening bolts to further fix the position of the right hanger, starts the motor to drive the left hanger to open, lowers the lifting block to insert the right hanger into the steel coil, and drives the motor to reverse to lower the left hanger and insert the left hanger into the steel coil. At this time, the steel coil is fixedly clamped between the left hanger and the right hanger, so that the lifting block can stably lift the steel coil, reducing the possibility of deformation or falling of the steel coil during lifting.

[0004] However, during the lifting process of the above-mentioned device, if the staff is fatigued for a long time or operates carelessly and violates regulations, especially when there is oblique lifting, the steel coil will shake unsteadily due to inertia after lifting, causing collision and injuring the staff, or even casualties. Utility Model Content

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 3 As shown, an embodiment of the utility model proposes a steel coil lifting and handling device, which includes a moving crossbeam 1 and a lifting device 101 arranged on the moving crossbeam 1, a balance beam 4, which is connected to the lifting device 101 through a steel cable 102 and is located directly below the lifting device 101, and two movable L-shaped arms 6 are mirror-arranged on the balance beam 4, and the two L-shaped arms 6 are used to hook the steel coil; a driving device is arranged on the balance beam 4 and is transmission-connected to the two L-shaped arms 6, and the driving device is used to drive the two L-shaped arms 6 to move closer to or away from each other; a safety device includes a transmitting device arranged on the balance beam 4, a receiving device arranged on the lifting device 101, and an alarm element 403 for detecting the relative position of the balance beam 4 and the lifting device 101, and the positions of the transmitting device and the receiving device are corresponding and parallel to each other; wherein the transmitting device emits a light source perpendicular to the ground, and the light source irradiates the receiving device to form a detection system, which is used to detect whether the lifting device 101 and the balance beam 4 are perpendicular before lifting.

[0022] The detailed working process of this embodiment is: the driving device drives the two L-shaped arms 6 to move closer to or away from each other, so as to clamp and lift different steel coils. The moving beam 1 and the lifting device 101 set on the moving beam 1 are both traditional lifting components, and the working principle will not be described in detail here.

[0023] Before lifting, the transmitting device on the balance beam 4 transmits a light source perpendicular to the ground. The light source shines on the receiving device. The light source is in a safe state within the detection range of the receiving device, and the lifting is in a vertical lifting state. If the light source deviates from the detection range of the receiving device, it is a lifting abnormality. The alarm 403 alarms to remind the staff. In this state, it means that the balance beam 4 and the lifting device 101 are not in a vertical lifting state, and there is a risk of swinging when the steel coil is lifted.

[0024] like Figure 2 and Figure 3 As shown, the transmitting device includes a lower ring frame 3 arranged on the upper side of the balance beam 4 and a plurality of groups of laser sensors 301 evenly distributed on the lower ring frame 3 .

[0025] The detailed working process of this embodiment is as follows: the lower ring frame 3 is used to install the laser sensor 301. At least three laser sensors 301 are installed on the lower ring frame 3. The more the number of laser sensors 301 installed within a certain range, the more sensitive the detection. When installing the laser sensor 301, it is necessary to ensure that the sensing laser 302 of each laser sensor 301 is perpendicular to the balance beam 4.

[0026] like Figure 2 and Figure 3 As shown, the receiving device includes an upper ring frame 2 arranged at the lower side of the lifting device 101 and a laser reflection plate 201 arranged on the upper ring frame 2, wherein the sensing lasers 302 emitted by the multiple groups of laser sensors 301 are all irradiated onto the laser reflection plate 201.

[0027] The detailed working process of this embodiment is as follows: the upper ring frame 2 is fixedly set on the lifting device 101, and a circle of laser reflection plates 201 are set on the upper ring frame 2, so that the sensing lasers 302 emitted by multiple groups of laser sensors 301 are all irradiated onto the laser reflection plates 201. Within a certain range, the narrower the laser reflection plates 201, the more sensitive the induction. Only when the sensing lasers 302 emitted by multiple groups of laser sensors 301 are all irradiated onto the laser reflection plates 201, the balance beam 4 and the lifting device 101 are in a vertical state, and in this state, the lifting rigid coil will not swing significantly.

[0028] like Figure 1 As shown, a control box 402 is provided on the balance beam 4 , wherein the alarm element 403 and the plurality of groups of laser sensors 301 are electrically connected to the control box 402 .

[0029] The detailed working process of this embodiment is as follows: the alarm component 403 and multiple groups of laser sensors 301 are electrically connected to the control box 402. The laser sensor 301 sends a signal to the alarm component 403 through electrical connection, and the alarm component 403 sends an alarm signal. This function can be achieved through simple circuit control. At the same time, a safety module can also be set. When the laser sensor 301 is offset, the alarm component 403 sends an alarm signal and shields the signal of the remote control lifting device 101, preventing it from lifting.

[0030] like Figure 2 As shown, a T-shaped portion 601 is disposed at the upper end of each L-shaped arm 6 , a T-shaped slot 404 is provided on the balance beam 4 , and the T-shaped portion 601 is located in the T-shaped slot 404 and is slidable.

[0031] like Figure 2 As shown, the driving device includes a driving source 502 arranged on the balance beam 4, and a bidirectional screw rod 5 rotatably arranged in the T-shaped slot 404, the bidirectional screw rod 5 is threadedly connected to the two T-shaped parts 601 respectively, wherein the output shaft of the driving source 502 and one end of the bidirectional screw rod 5 are both provided with a spur gear 501, and the two spur gears 501 are meshed with each other.

[0032] The detailed working process of this embodiment is as follows: the two L-shaped arms 6 are driven by the bidirectional screw rod 5 , and the driving source 502 drives the bidirectional screw rod 5 to rotate through the spur gear 501 , so as to control the distance between the two L-shaped arms 6 .

[0033] The driving source 502 in this embodiment is a motor. In other embodiments, a suitable driving device can be selected according to actual conditions.

[0034] like Figure 2 As shown, each L-shaped arm 6 is provided with a plurality of receiving grooves 605 , and each receiving groove 605 is provided with a roller 604 .

[0035] The detailed working process of this embodiment is as follows: the function of the roller 604 is to prevent the side wall of the steel coil from directly rubbing against the L-shaped arm 6 when the steel coil is lifted or lowered, thereby preventing the steel coil from being damaged.

[0036] like Figure 2 As shown, the force-bearing surface of each L-shaped arm 6 for lifting the steel coil is an arc surface, and a rubber pad 606 is provided on the arc surface.

[0037] The detailed working process of this embodiment is as follows: the function of the arc surface is to increase the contact surface between the L-shaped arm 6 and the steel coil to avoid indentation caused by its own gravity.

[0038] like Figure 2 As shown, a protective cover 503 is provided on the balance beam 4 , and two mutually meshing spur gears 501 are located inside the protective cover 503 .

[0039] The detailed working process of this embodiment is as follows: the protective cover 503 protects the spur gear 501 to prevent it from being corroded and damaged.

[0040] The implementation principle of the embodiment of the present application is: before lifting, the laser sensor 301 on the balance beam 4 emits an induction laser 302 perpendicular to the ground. The light source is irradiated on the laser reflection plate 201. The light source is in a safe state within the detection range of the laser reflection plate 201, and the lifting belongs to a vertical lifting state. If the light source deviates from the detection range of the laser reflection plate 201, it is a lifting abnormality, and the alarm component 403 alarms to remind the staff. In this state, it means that the balance beam 4 and the lifting device 101 are not in a vertical lifting state.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
