Description

Technical Field

[0001] The invention relates to the technical field of industrial copper melting, and in particular to a crane hoist based on industrial copper coils and a copper coil storage rack. Background Art

[0002] With the rapid development of industry, metal smelting and supporting finished product manufacturing have increasingly higher requirements for technological advancement and construction safety.

[0003] Traditional copper coil smelting process: logistics trucks transport copper coils, and people use traditional cranes and wire ropes to bind copper coil lifting rings and unload copper coils from trucks to the storage area on the first floor. When the copper coils smelted in the copper melting tank (diameter 4.5 meters, depth about 7 meters) are used up and need to be refilled, people first use traditional cranes and wire ropes to open and lift the copper melting tank lid (diameter 4.5 meters, height 0.5 meters, weight 1.3 tons) in the smelting workshop on the second floor, and transfer and stack it on the tank lid next to it. Then drive the crane to the copper coil storage area on the first floor, and then use traditional cranes and wire ropes to grab, transfer, and deliver the copper coils to the copper melting tank that needs to be refilled.

[0048] A cutting and binding strap mechanism 5 is provided on the side of the two sling bodies 26 that are away from each other.

[0049] The lifting device in this embodiment is aimed at the industrial copper coil 10 of the above embodiment, and the clamping assembly cooperates with the lifting disc on the tank cover in the above embodiment to realize the lifting of the copper coil 10. Specifically, the crane adopts a European crane structure, and the trolley and the car use an absolute value rotary encoder and a photoelectric sensor 9 positioning system with a repeat positioning accuracy of 10mm. In addition to 2 sets of lifting wire ropes, a set of 4-section retractable rigid telescopic cylinder structure is designed between the crane and the lifting device, and a PLC electrical anti-sway control system is equipped. The crane can operate stably under various working conditions, reducing the negative swing effect of the lifting device due to acceleration and deceleration inertia.

[0050] The two sling bodies 26 are driven by the bidirectional screw 25 to move toward or in opposite directions. When the copper coil 10 needs to be grabbed, the two sling bodies 26 are close to each other. At the same time, a groove 3 is provided on the side where the two sling bodies 26 are close to each other. The size of the groove 3 is adapted to the size of the lifting disc, and a support portion 4 is formed at the bottom of the groove 3. When the two sling bodies 26 are close to each other, the grooves 3 on the two sling bodies 26 clamp the lifting disc from both sides, and the support portion 4 is placed at the bottom of the lifting disc, thereby fixing the lifting disc, and completing the lifting of the copper coil 10 through the telescopic assembly 22;

[0051] The above-mentioned bidirectional screw 25 is arranged in the sling mounting seat 23, and the bidirectional screw 25 is rotatably connected to the sling mounting seat 23. A driving mechanism 12 is arranged on one side of the bidirectional screw 25 to drive the rotation of the bidirectional screw 25. The two ends of the two-way screw 25 penetrate the two sling bodies 26 and are threadedly connected to the bidirectional screw 25. The rotation of the bidirectional screw 25 can drive the two sling bodies 26 to move closer to or away from each other; wherein, the driving mechanism 12 includes a driving motor and a motor reducer, the driving motor and the motor reducer are both fixedly connected to the sling mounting seat 23, and the driving motor and the motor reducer are transmission-connected to the bidirectional screw 25.

[0052] The up and down movement of the sling body 26 is completed by the telescopic component 22. The telescopic component 22 includes a rigid four-section telescopic cylinder structure, which is provided with a movable end and a fixed end. The fixed end is fixed on the traveling mechanism 1, and the telescopic component 22 is driven to move horizontally by the traveling mechanism 1. The movable end is fixed on the sling mounting seat 23, and the sling mounting seat 23 is driven to move in the vertical direction by the telescopic movement of the movable end. The sling mounting seat 23 moves simultaneously with the movable end. Two fixed pulleys 24 are installed on the sling mounting seat 23, and two winding motors are installed on the traveling mechanism 1. One end of the lifting rope 21 is fixed on the traveling mechanism 1, and the other end passes through the fixed pulley 24 and is connected to the winding motor. The lifting rope 21 is wound by the winding motor to drive the sling mounting seat 23 to move up and down.

[0053] The winding motor can use the existing winding structure to complete the winding of the lifting rope 21; the driving mechanism 1 adopts a European crane structure, and the trolley and the car use an absolute value rotary encoder and a photoelectric sensor 9 positioning system, which will not be repeated here.

[0054] The strap cutting mechanism 5 arranged outside the sling body 26 can cut the strap 11 of the copper coil 10 when the sling body 26 is hoisting the copper coil 10 and placing it above the copper melting tank, and then put the copper coil 10 into the copper melting tank.

[0055] In a further embodiment, the cutting and binding belt mechanism 5 includes a rotating cutter disc 51, a slide groove penetrating to the outside of the sling body 26 is opened in the groove 3 of the sling body 26, a linear moving mechanism 53 is arranged on the outside of the sling body 26, a turntable motor 54 is arranged on the linear moving mechanism 53, the output end of the turntable motor 54 is fixedly connected to the rotating cutter disc 51, driving the rotating cutter disc 51 to rotate, the rotating cutter disc 51 extends into one side of the groove 3 of the sling body 26 through the slide groove, and the linear moving mechanism 53 drives the turntable motor 54 and the rotating cutter disc 51 to move along the direction of the slide groove;

[0056] The linear motion mechanism 53 and the turntable motor 54 are both electrically connected to the control system.

[0057] The above-mentioned strap cutting mechanism 5 includes a rotating cutter disc 51, which has blade teeth for cutting the strap 11 of the copper coil 10. The rotating cutter disc 51 is driven to rotate by a turntable motor 54 to cut the strap 11 of the copper coil 10. The initial position of the rotating cutter disc 51 is set at the edge of the outer side of the sling body 26, which will not affect the transportation of the copper coil 10. When it is necessary to cut the strap 11, the linear moving mechanism 53 is used to drive the turntable motor 54 and the rotating cutter disc 51 to move linearly, and the rotating cutter disc 51 extends into the inner part of the sling body 26 to cut the strap 11.

[0058] The two sling bodies 26 are provided with limit sensors, and each sling body 26 is provided with two limit sensors, one of which is correspondingly provided at the maximum position of the sling, and the other limit sensor is correspondingly provided at the minimum position after the sling body 26 clamps and fixes the copper coil 10;

[0059] The two hanger bodies 26 are both provided with proximity sensors, and the proximity sensors are arranged at the position where the two hanger bodies 26 clamp the copper coil 10 to the minimum position;

[0060] The proximity sensor is electrically connected to the control system.

[0061] The limit sensor is electrically connected to the control system, and transmits the position signal of the sling body 26 to the control system.

[0062] The main body 26 of the spreader is designed and welded with high-quality carbon steel, with a rated load capacity of 2 tons. It adopts a single motor reducer and a bidirectional motion ball screw transmission structure. Under the premise of ensuring transmission efficiency, it can not only reduce the number of drive sources and simplify electrical control, but also meet the design requirements of synchronous opening and closing of the two-side structures of the spreader. Four travel limit sensors are designed and installed above the spreader. In addition to the electrical control limit of the encoder provided by the motor, the four travel limit sensors respectively perform secondary limit protection on the maximum opening position and the minimum closing position of the spreader. A proximity sensor is installed on each side wall of the sling. When the motor drives the sling to close to the designed distance from the copper coil 10, the sensor senses and sends a signal. The PLC receives the signal and controls the motor to stop moving. Two linear motion mechanisms and a rotating cutter disc 51 are designed at the bottom of the sling. Before the copper coil 10 is fed, the motor of the rotating cutter disc 51 is started to drive the cutter disc to rotate rapidly. The linear motion mechanism pushes the cutter disc to the position of the copper coil 10 strap 11 until the strap 11 is completely cut off, and the rotating cutter disc 51 automatically returns to its original position and stops rotating.

[0063] Cameras are provided on the tops of the two sling bodies 26;

[0064] The camera is electrically connected to the control system.

[0065] The linear moving mechanism 53 includes a moving motor, which is fixedly connected to one side of the hanger body 26. The output end of the moving motor is fixedly connected to a guide screw 531, and a guide seat is provided on the guide screw 531. The guide seat is threadedly connected to the guide screw 531, and the guide seat is slidably connected to the outer side of the hanger body 26. The turntable motor 54 is fixedly connected to the guide seat.

[0066] The above-mentioned movable motor is fixed on the outside of the hanger body 26, and a guide screw 531 is fixed at its output end. Through the rotation of the guide screw 531, the guide seat threadedly connected to it is driven to move horizontally along the guide screw 531. The guide seat is slidingly connected to the hanger body 26, and the turntable motor 54 fixed on the guide seat moves accordingly to drive the rotating cutter disc 51 to move linearly to cut the copper coil 10 and the strap 11.

[0067] like Figure 8-Figure 11 As shown, in another embodiment, a copper coil 10 storage rack is also disclosed, including a frame body composed of two parallel brackets 6 arranged at intervals, a placement seat 7 is fixedly connected between the two brackets 6, a plurality of placement seats 7 are provided, and a plurality of placement seats 7 are linearly arrayed on the frame body, and a cylindrical guide column 8 is fixedly connected to the top of the placement seat 7, and the guide column 8 is adapted to the inner diameter of the copper coil 10 and is used to place the copper coil 10;

[0068] The distance between the two brackets 6 is smaller than the outer diameter of the copper coil 10 , so that a lifting tool can clamp the copper coil 10 on both sides of the copper coil 10 , and the lifting tool is the above-mentioned crane lifting tool.

[0069] Each of the placement seats 7 is provided with a photoelectric sensor 9 on one side of the guide column 8 for detecting whether there is a copper coil 10 on the corresponding placement rack.

[0070] A copper coil 10 storage rack is designed to hold the copper coils 10 loaded and unloaded from the truck. The copper coils 10 are guided and positioned by guide columns 8. Two groups of thick copper straps 11 with a diameter of φ8 are symmetrically arranged at 180°. A photoelectric sensor 9 is designed at each copper coil 10 placement position on the storage rack to monitor whether there is a copper coil 10 above the storage rack, thereby providing necessary information data for remote automated grabbing of the copper coils 10.

[0071] Working principle:

[0072] When the crane is retrieving materials, the calibrated coordinates of the copper coil 10 and the photoelectric sensor 9 of the copper coil 10 reserve rack detect signals. The crane automatically goes to the numbered position where the copper coil 10 is located according to the system program to grab the copper coil 10. The sling is first opened to the maximum position, and the hoisting rope 21 and the rigid telescopic cylinder lower the sling to the bottom of the copper coil 10. The motor ball screw mechanism (bidirectional screw 25) on the sling controls the closure of the two sides of the sling body 26. When the limit sensors on both sides of the sling body 26 sense signals, they send out signals synchronously. The PLC receives the signals to control the motor ball screw to stop moving and self-lock. The open position of the sling is fixed, and the automatic retrieving and fixing of the copper coil 10 is completed.

[0073] When the crane transfers the copper coil 10, the copper melting tank has been opened and the coordinates of each copper melting tank have been calibrated. The crane automatically lifts the copper coil 10 and transfers it to the second floor smelting area directly above the copper melting tank where the copper coil 10 needs to be added. The camera on the hoist monitors the image, and the operator selects the serial number point where the material is missing in the copper melting tank and needs to be added (such as Fig.12 As shown in the figure, click on the specific position 1-9 where the material needs to be fed through the remote operation platform, and the crane automatically moves the copper coil 10 to the coordinate above the final feeding point, thus completing the transfer of the copper coil 10.

[0074] When the sling cuts the binding strap 11, the turntable motor 54 of the rotating cutter disc 51 starts automatically, driving the cutter disc to rotate rapidly, and the linear moving mechanism 53 pushes the cutter disc to the position of the binding strap 11 of the copper coil 10 until the binding strap 11 is completely cut off. The rotating cutter disc 51 automatically returns to its original position and stops rotating. Then the motor ball screw starts, the sling opens, and the copper coil 10 completes the feeding under the action of gravity.

[0075] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0076] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features).
