Description

Technical Field

[0001] The utility model relates to the technical field of cable reel equipment, in particular to a cable reel which is convenient to move and has two driving modes. Background Art

[0002] The cable reel is a widely used mechanism, which mainly provides winding functions of power supply, control power supply or control signal cable for electric equipment, and is widely used in port cranes, container cranes, ship loaders, tower cranes, mobile electric equipment (such as welding machines), etc. The cable reel is generally driven by machine drive, human drive and scroll spring, etc. (the cable reel shaft is installed with an electric slip ring. According to the different positions of the electric slip ring installed on the frame, the head end of the cable wound on the outer end of the reel is connected to the outer ring or inner ring of the electric slip ring rotating at the side end of the reel shaft, and the power supply or signal, control power cable end is connected to the inner ring or outer ring of the fixed electric slip ring, so that the reel can supply power to the corresponding equipment or output signals, control power, etc. when winding the cable); among them, the machine drive mainly drives the cylinder to retract and release the cable through the motor reduction mechanism, the scroll spring drive mainly relies on the elastic force of the spring to retract and release the cable, and the human drive retracts the cable by manually rotating the cylinder.

[0003] Although the existing cable reels meet the needs of practical applications to a certain extent, they are still limited by the structure and have some specific problems to be solved as follows. First, the existing cable reels used for mobile electrical equipment (such as electric welders, electric drills, etc.) are heavy because they need to be manually moved to the work area by the staff. When the position is relatively frequently moved with the working range, it will cause inconvenience to the staff, which is not conducive to improving work efficiency. Second, the electric-driven cable reel and the manually-driven cable reel only have a single working mode. The electric-driven cable reel cannot work normally when there is no power supply on site, and the manually-driven cable reel completely relies on manpower to retract and release the cable, which will cause inconvenience to the staff and increase the labor intensity (the cable reel driven by the spiral spring needs to overcome the spring's reeling elastic force to pull out the cable when unwinding the cable, so the required pulling force is large, which will also cause inconvenience to the staff and increase the labor intensity); Third, the control of the electric-driven cable reel requires the staff to manually approach and operate the corresponding power switch, and the control method is not flexible, which will also cause inconvenience to the staff. In summary, it is very necessary to provide a cable reel suitable for use in mobile electrical equipment, etc., which is easy to move, has both electric drive and manual drive, and can wirelessly control the electric drive working mode. Utility Model Content

The shafts in the middle of the two side ends of the reel 2 are respectively tightly sleeved in the inner rings of the two bearings 31 and the shafts 31 at the two side ends of the reel are respectively located on the left and right ends of the two sets of support frames. The right end shaft 31 has an external thread, and an internal threaded sleeve 41 is horizontally welded to the lower left side end of the operating rod 4; a support plate 103 is horizontally welded to the upper left side of the left end support frame, and the motor reduction mechanism M is bolted to the left end of the support plate 103. A circular connecting plate 7 is welded to the right side end of the rotating shaft of the motor reduction mechanism, and the connecting plate 7 has three thread holes distributed in an annular manner. A fixing bolt 71 is screwed in and installed in each thread hole horizontally, and a circular fixing plate 8 is welded outside the shaft at the left end of the cylinder, and the fixing plate 8 has three thread holes distributed in an annular manner; the power module W1 and the wireless receiving circuit 5 are installed on the circuit board in the electric control box 9, and the electric control box 9 is installed on the middle of the rear end of the bottom plate.

[0016] Figure 1 , 2As shown in , the sleeve 41 of the operating rod and the right end shaft rod are connected together by threads, and the right ends of the three bolts 71 of the connecting plate are screwed into the three threaded holes of the fixing plate 8. The upper end of the threaded rod has a through hole as an operating hole 621 (a metal rod is inserted to rotate the threaded rod). When the threaded rod 62 of the positioning mechanism is at the lower dead center, the lower end of the limit plate 63 contacts the ground. The wireless receiving circuit includes a wireless receiving circuit module W2 and relays K1 and K2 connected by circuit board wiring, the positive power input terminal 1 of the wireless receiving circuit module W2 is connected to the positive control power input terminals of the two relays K1 and K2, and the negative power input terminals and negative control power input terminals of the two relays K1 and K2 are connected to the negative power input terminal 2 of the wireless receiving circuit module W2. The power input terminals 1 and 2 of the power module W1 are connected to the two poles of the AC 220V power supply via wires, respectively; the power output terminals 3 and 4 of the power module W1 are connected to the power input terminals 1 and 2 of the wireless receiving circuit module W2 via wires, respectively; the two normally open contact terminals of the two power output terminal relays K1 and K2 of the wireless receiving circuit are connected to the positive and negative and negative and positive and negative power input terminals of the motor reduction mechanism M via wires, respectively.

[0017] Figure 1 , 2As shown in the figure, the present invention is mainly used for mobile electrical equipment. Since the lower end of the bottom plate is provided with wheels, the staff can conveniently push the equipment as a whole to the relevant working station through the push rod 101. After it is in place, the staff use metal rods to respectively insert the upper end operating holes 621 of the threaded rods of the four sets of positioning mechanisms, and then rotate the threaded rods clockwise. The lower end of the limit plate 63 stops rotating after contacting the ground. In this way, the positioning mechanism can be used to stably position the equipment as a whole in the working position (to prevent the overall displacement of the equipment when the cable is retracted and released); when the work is completed and the position needs to be transferred, the threaded rod is rotated counterclockwise, and the lower end of the limit plate 63 gradually stops contacting the ground, so that the equipment as a whole can be conveniently moved to another working position. When there is no power supply on site, the staff connects the sleeve 41 of the operating rod and the right end shaft of the drum 2 through threads, so that when the staff rotates the operating rod clockwise, the drum 2 will reel in the cable (when unwinding the cable, the staff manually pulls the head end of the cable to unwind); after the subsequent work is completed, the staff holds the upper right end of the cylinder 2 with his left hand, and then rotates the operating rod counterclockwise, so that the operating rod can be easily removed and placed in the equipment box. When there is power supply on site, the staff uses a wrench to screw the right ends of the three bolts 71 of the connecting plate into the three thread holes of the fixing plate 8, so that when the rotating shaft of the motor reduction mechanism M rotates, it will synchronously drive the drum 2 to rotate and retract the cable. After the staff uses a wrench to screw the right ends of the three bolts 71 of the connecting plate out of the three thread holes of the fixing plate 8, the rotating shaft of the motor reduction mechanism M will no longer drive the drum 2 to rotate and retract the cable when it rotates, so that the staff can manually rotate the drum to retract the cable later. In the electric mode, the staff member presses the first transmitting button S1 or the second transmitting button S2 of the portable wireless remote control mechanism W3 with his finger, and the wireless remote control mechanism W3 transmits the first or second wireless closing signal. After the wireless receiving circuit module W2 receives it, its 3rd or 4th foot will output a high level to the positive power input end of the relay K1 or K2. The relay K1 or K2 is energized to attract its control power input end and the normally open contact end to close, and then the positive and negative or negative and positive power input ends of the motor reduction mechanism M will be energized. After the positive and negative power input ends of the motor reduction mechanism M are energized, its rotating shaft will drive the cylinder to rotate clockwise to reel in the cable; after the negative and positive power input ends of the motor reduction mechanism M are energized, its rotating shaft will drive the cylinder to rotate counterclockwise to unwind the cable. After the cable is reeled in place, the staff member presses the first transmitting button S1 or the second transmitting button S2 of the portable wireless remote control mechanism W3 with his finger again, and the wireless remote control mechanism W3 transmits the first or second wireless open-circuit signal, and the 3rd or 4th foot of the wireless receiving circuit module W2 will stop outputting a high level and enter the positive power input terminal of the relay K1 or K2. When the relay K1 or K2 loses power, it will no longer attract its control power input terminal and the normally open contact terminal to open the circuit. Furthermore, the positive and negative or negative and positive power input terminals of the motor reduction mechanism M will lose power, and the reel will no longer retract or release the cable.

[0018] Through the combined action of all the above mechanisms, the staff can manually retract and release the cable through the operating rod, and through the wireless remote control mechanism and the wireless receiving circuit, the staff can wirelessly control the cylinder to retract and release the cable. This new device brings convenience to the staff and correspondingly improves work efficiency. Figure 2 Among them, relays K1 and K2 are DC 24V relays; power module W1 is a finished product of AC 220V to DC 24V switching power module; wireless transmitting circuit module W3 and wireless receiving circuit module W4 are finished products of wireless transmitting and receiving circuit module components of model FM200, and the wireless signal receiving and sending distance is 200 meters (consistent with the principle of automotive wireless remote control components); motor reduction mechanism M is a finished product of a coaxial motor gear reducer with a working voltage of DC 24V and a power of 500W.
