Description

Technical Field

[0001] The utility model relates to the technical field of cable reel equipment, in particular to a cable reel device which can conveniently assemble and disassemble the reel. Background Art

[0002] Cable reels (electrically driven reeling reels) are widely used mechanisms, primarily providing power, control, or signal cable winding for electric equipment. They are widely used in port cranes, container cranes, ship loaders, tower cranes, mobile electric equipment (such as welding machines), and cable manufacturers. Cable reels are typically powered by machines, humans, or scroll springs. Machine-driven cable reels used in cable production are categorized by power source, including motor reduction mechanisms and hydraulic motors. Motor-driven cable reels (hereinafter referred to as cable reels) are widely used due to their ease of control and compact structure. (The motor reduction mechanism of the cable reel drives the reel to reel in or unreel the cable.) In the actual application of the cable reel, in order to achieve orderly reeling and unreeling of the cable on the reel (generally only the cable is reeled), an electric guide mechanism is installed on the front end of the cable reel. Under the control of the cable reel's supporting control system, the electric guide mechanism moves back and forth left and right, so that the cable can move horizontally from left to right and from right to left to be evenly wound on the reel, or unwound from the reel.

[0003] Although the existing cable reels used for cable production have met the actual production needs to a certain extent, they still have some problems that need to be improved due to structural limitations. Specifically, the power output shaft of the cable reel and the rectangular or other special-shaped sleeve connected to the fixed seat at the other end, in order to facilitate the special-shaped connecting rods on the outer sides of the two ends of the reel to be put into the sleeve, the upper end of the sleeve is generally an open structure. Before reeling the cable, the reel without reeling the cable and the connecting rods on both sides are put into the sleeve from top to bottom by hoisting or other means, and then multiple bolts are manually passed through the two openings at the rear ends of the two sleeves and the two openings at the front ends of the sleeve longitudinally, and fixing nuts are screwed into the front ends of the bolts to fix the sleeve and the connecting rods on both sides of the reel together. During operation, the motor reduction mechanism drives the rotation of the connecting rod on the left side of the reel through the rotating shaft (power output shaft) sleeve, and the connecting rod on the right side of the reel moves with the bearing of the fixed seat through the sleeve, and then the reel reels the cable, etc. After the cable is reeled in the above way, the staff needs to remove the multiple bolts and nuts, and then lift the reel with the reeled cable away by hoisting or other means, and replace it with a new reel without the reeled cable. In the above working mode, since the installation and disassembly of the reel requires the staff to manually insert the bolts and tighten the nuts with a wrench, or loosen the nuts and remove the bolts with a wrench, it will cause great inconvenience to the staff, increase the staff's labor intensity, and accordingly, it is not conducive to improving work efficiency. In summary, it is particularly necessary to provide a cable reel device that can easily install and remove the reel. Utility Model Content

[0016] Figure 1 、 2As shown in Figures 3 and 4, a cable reel device that can be easily disassembled and assembled comprises a cable reel body with an electric guide mechanism 1, a base plate 2, a sleeve 3, a motor reduction mechanism 4, a fixing seat 5, a reel 6 (with multiple pieces), a power module A1, an electric linear slide M1, and a wireless remote control A3. An outer hexagonal connecting rod 61 is welded in the middle of each end of the reel. The electric guide mechanism 1 is laterally mounted on the front end of the base plate 2 by bolts, and also has a wireless receiving circuit 8 and an in-position prompt mechanism. There are at least two sleeves 3, which are closed structures all around and have an open structure 31 at the inner end. The inner side 31 of the sleeve is an inner hexagonal structure. The electric linear slide M1 is laterally mounted on the upper left end of the rear of the base plate 2 by bolts. A fixed platform 7 is welded on the sliding block of the electric linear slide. The lower end of the motor reduction mechanism 4 is bolted. Mounted on the fixed platform 7, the right end of the rotating shaft of the motor reduction mechanism 4 and the middle part of the left outer end of the first sleeve 3 are welded together, the lower end of the fixed seat 5 is welded to the upper right side end of the rear base plate 2, and the two bearing inner rings installed in the middle part of the upper end of the fixed seat 5 are tightly sleeved with a shaft 51, and the left end of the shaft 51 and the middle part of the right outer end of the second sleeve 3 are welded together; the in-position prompt mechanism includes two reed switches GH1 and GH2, a buzzer B, and two magnets CT1 and CT2. The two magnets CT1 and CT2 are respectively glued to the lower left and right ends of the front of the sliding block, and the two reed switches GH1 and GH2 are respectively glued to the left and right sides of the front end of the shell of the electric linear slide M1; the power module A1, wireless receiving circuit 8, and buzzer B are installed on the circuit board in the component box 9, and the component box 9 is installed on the middle part of the right end of the base plate.

[0017] Figure 1 、 2As shown in Figures 3 and 4, the two sleeves 3 are horizontally located in the same plane. The outer shape of the inner side of the sleeve 3 is consistent with that of the connecting rod 61, and the outer diameter of the connecting rod 61 is slightly smaller than the inner diameter of the sleeve 3. The upper end height of the two reed switches GH1 and GH2 is slightly lower than the lower end height of the two magnets CT1 and CT2 (1 mm) and is located in the same vertical plane. The reed switches GH1 and GH2 are normally open contact reed switches with the moving contact located at the lower end and the static contact located at the upper end. When the sliding block of the electric linear slide M1 is at the left dead center, the distance between the inner sides of the two sleeves 3 is greater than the distance between the outer sides of the connecting rods 61 on both sides of the drum 6. When the sliding block of the electric linear slide M1 is at the right dead center, the distance between the two sleeves 3 is smaller than the distance between the outer sides of the connecting rods 61 on both sides of the drum 6. The wireless receiving circuit includes a wireless receiving circuit module A2 and relays K1 and K2 connected via circuit board wiring. The positive power input terminal 1 of the wireless receiving circuit module A2 is connected to the positive control power input terminals of the two relays K1 and K2. The two power output terminals 3 and 4 of the wireless receiving circuit module A2 are respectively connected to the positive power input terminals of the two relays K1 and K2. The negative power input terminal 2 of the wireless receiving circuit module A2 is connected to the negative power input terminals and negative control power input terminals of the relays K1 and K2. The power input terminals 1 and 2 of the power module A1 are connected to the two levels of the AC 220V power supply via wires respectively. The power output terminals 3 and 4 of the power module A1 are connected to the power input terminals 1 and 2 of the wireless receiving circuit module A2, and the power input terminals of the two reed switches GH1 and GH2 (pin 3 of the power module A1) are connected via wires. The power output terminals of the two reed switches GH1 and GH2 and the negative power output terminal 4 of the power module A1 are connected to the power input terminal of the buzzer B via wires. The normally open contact terminals of the power output terminal relays K1 and K2 of the wireless receiving circuit and the positive and negative and negative and positive and negative power input terminals of the electric linear slide M1 are connected via wires respectively.

[0018] Figure 1 、 2As shown in Figures 3 and 4, when the motor reduction mechanism 4 (2.5KW) is powered on (after the power switch of the motor reduction mechanism is turned on), its rotating shaft drives the left end sleeve 3 to rotate clockwise, and the left end sleeve 3 drives the reel 6 to rotate on the left side. The reel 6 rotates along the bearing along the shaft 51 of the fixed seat 5 via the right end connecting rod 61, and the sleeve 3 rotates along the bearing. In this way, the reel 3 will reel or unreel the produced cable (rotate counterclockwise). In the actual application of the cable reel body, in order to realize the orderly reeling and unreeling of the cable on the reel 6, an electric guide mechanism 1 is installed at its front end. Under the control of the matching control system of the cable reel body, the electric guide mechanism 1 moves back and forth left and right, so that the cable can move horizontally from left to right or from right to left and be evenly wound on the reel 6, or unreeled from the reel 6 (the above is a mature technology and will not be repeated in this application). After the AC 220V power supply enters the power input terminal of the power module A1, the 3rd and 4th pins of the power module A1 output a stable DC 24V power supply which enters the power input terminal of the wireless receiving circuit module A2. The wireless receiving circuit module A2 is powered on and starts working. After the reel 6 finishes winding up the cable, the staff uses two slings to respectively distribute them in a circular manner on both sides of the reel 6. The upper ends of the slings are hung together with the hooks of the lifting equipment (such as an overhead crane). Then the staff presses the first button S1 of the wireless remote control A3 carried with them. The wireless remote control A3 transmits the first wireless closing signal. After the wireless receiving circuit module A2 receives the first wireless closing signal, its 3rd pin outputs a high level which enters the positive power input terminal of the relay K1. The relay K1 is energized to close its control power input terminal and the normally open contact terminal. In this way, the electric linear slide The positive and negative power input terminals of M1 are energized, and the sliding block of the electric linear slide M1 drives the motor reduction mechanism 4 and the fixed platform, the left end sleeve, etc. to move toward the left end. In this way, the left end sleeve 3 and the left connecting rod 61 of the reel are separated, and then the crane operator lifts the reel to the left end, and the connecting rod at the right end of the reel is separated from the right end sleeve. In this way, the lifting personnel can lift the reel of the cable that has been wound up; then, the staff presses the first button S1 of the wireless remote control A3 again by hand, and the wireless remote control A3 transmits the first wireless open circuit signal. After the wireless receiving circuit module A2 receives the first wireless closed signal, its 3rd pin stops outputting a high level and enters the positive power input terminal of the relay K1. When the relay K1 loses power, it no longer attracts the control power input terminal and the normally open contact terminal to open, and the electric linear slide no longer receives power to work.When a reel has finished reeling up the cable, the hoisting personnel put the empty reel without reeling up the cable between the two sleeves, and the staff pressed the second button S2 of the wireless remote control A3 carried with them. The wireless remote control A3 transmits the second wireless closing signal. After the wireless receiving circuit module A2 receives the second wireless closing signal, its 4-pin output is high level and enters the positive power input terminal of the relay K2. The relay K2 is energized and its control power input terminal and the normally open contact terminal are closed. In this way, the negative and positive power input terminals of the electric linear slide M1 are energized, and the sliding block of the electric linear slide M1 drives the motor reduction mechanism 4 and the fixed platform, the left end sleeve, etc. to move to the right end. In this way, the left end sleeve 3 is combined with the left end connecting rod 61 of the reel (the connecting rod enters the sleeve. Specifically, the staff can temporarily turn on the motor The power switch of the deceleration mechanism, the motor deceleration mechanism shaft drives the left end sleeve to rotate a certain angle, or the right sleeve is rotated by hand so that the angles of the connecting rods at the inner ends of the two sleeves and the two side ends of the reel are aligned, so that the two sleeves are respectively sleeved in the two connecting rods), and the connecting rod at the right end of the reel enters the right end sleeve; then, the staff presses the second button S2 of the wireless remote control A3 again by hand, and the wireless remote control A3 transmits the second wireless open circuit signal. After the wireless receiving circuit module A2 receives the second wireless closed signal, its 4-pin stops outputting a high level and enters the positive power input terminal of the relay K2. When the relay K2 loses power, it no longer attracts the control power input terminal and the normally open contact terminal to open the circuit, and the electric linear slide no longer receives power to work; finally, the staff removes the sling and can start the work of winding the cable on the next reel.

[0019] Figure 1 、 2As shown in , 3, and 4, in this application, in the specific operation, it is necessary to remove the reel of the wound cable, and the sliding block of the electric linear slide M1 is close to the left dead center. At this moment, the magnet CT1 just moves to the upper end of the reed switch GH1, and the internal contact of the reed switch GH1 is closed, so that the buzzer B will be energized and sound. After hearing the sound, the staff can intuitively know that the electric linear slide has driven the left end sleeve to move to the left and it is in place, and the wireless control can be stopped, and the operating sling can lift the wound reel; in the specific operation, it is necessary to fix the reel that has not been wound up with the cable, and the sliding block of the electric linear slide M1 is close to the right dead center (the two sleeves are completely covered on the outer ends of the two connecting rods respectively), at this moment, the magnet CT2 just moves to the upper end of the reed switch GH2, and the internal contact of the reed switch GH2 is closed, so that the buzzer B will be energized and sound. After hearing the sound, the staff can intuitively know that the electric linear slide has driven the left end sleeve to move to the right and it is in place, and the wireless control can be stopped and the lifting rope can be removed. Through the above, this new device allows workers to conveniently wirelessly control the reel, allowing the connecting rods on both sides of the reel to be easily separated or connected with the motor reduction mechanism and the sleeve inside the fixed base, thereby facilitating the lifting or fixing of the reel with lifting equipment, thereby bringing convenience to workers and correspondingly improving work efficiency. Power supply module A1 is a finished AC 220V to DC 24V switching power supply module; electric linear slide M1 is a finished electric lead screw slide with a power of 300W; buzzer B is a finished active continuous sound buzzer alarm model MF24V; wireless remote control A3 and wireless receiving circuit module A2 are finished wireless transmitting and receiving circuit modules model APDC-4PC-B. Wireless remote control A3 has four wireless signal transmission buttons, and wireless receiving circuit module A2 has four power output terminals (the principle is completely consistent with existing automotive wireless transmitting and receiving modules); reed switches GH1 and GH2 are normally open contact reed switches; relays K1 and K2 are DC24V models. Figure 4 The components are all mature products, and this application does not elaborate on their working principles.
