Description

Technical Field

[0001] The utility model relates to the technical field of cable reel equipment, in particular to an electric reel with multi-dimensional reeling angles. 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 as the power (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 is divided into motor reduction mechanism drive, hydraulic motor drive, etc. according to the power; the cable reel driven by the motor reduction mechanism (hereinafter referred to as the electric drive reel) is widely used due to its convenient control and compact structure (the motor reduction mechanism of the electric drive reel body drives the reel body to rotate to reel or unreel the cable). In the actual application of the cable reel driven by the motor reduction mechanism (hereinafter referred to as the electric drive reel), in order to realize the orderly sending and receiving of the cable on the reel, an electric guide mechanism is generally installed on the front end thereof. The electric guide mechanism moves back and forth left and right under the control of the control system supporting the electric drive reel, so that the cable can move horizontally from left to right, from right to left, and be mixed and wound on the reel, or unwound from the reel.

[0003] Although existing cable reels meet actual production needs to a certain extent, they are limited by their structure and can only retract and release cables at a certain angle. For example, for electrically driven loaders used for loading and unloading in cargo yards, the trajectory of their movement between the cargo pile and the vehicle cannot be a straight line. The cable reel installed on the vehicle has an irregular movement direction, which is very likely to cause the cable to be irregularly stored on the reel. When the outer diameter of the cable wound on one side of the reel is too large, there is a possibility that the cable will fall out from the side end baffle of the reel, thus increasing the possibility that the cable will be damaged or even broken by the winding of the reel shaft. In summary, it is particularly necessary to provide a cable reel that can easily rotate to retract and release the cable and minimize cable damage. Utility Model Content

[0004] In order to overcome the drawbacks of existing electric drive reels as described in the background technology due to structural limitations, the utility model provides an electric drive reel based on an electric drive reel body.

The power supply mechanism W1, the rectifier circuit 61 of the detection mechanism, and the alarm prompt circuit 5 are installed on a circuit board in the component box 7 in the cab.

[0016] Figure 1 , 2As shown, the outer side of the magnet 62 and the inner side of the coil M are spaced apart. The outer diameter of the lower support plate 4 is greater than the outer diameter of the fixed plate 2, and the lower ends of the four sets of supporting wheels 3 are in sliding contact with the upper end of the lower support plate 4. The rectifier circuit of the detection mechanism includes a bridge stack W2, a capacitor C1, resistors R1 and R2 connected by circuit board wiring, and connected to the generating coil M via a wire, the two ends of the coil M are respectively connected to the two ends 1 and 2 of the power input of the bridge stack W1, the positive power output terminal 3 of the bridge stack W1 is connected to the positive pole of the capacitor C1 and one end of the first resistor R1, the other end of the first resistor R1 is connected to one end of the second resistor R2, and the negative power output terminal 4 of the bridge stack W2 is connected to the negative pole of the capacitor C1 and the other end of the second resistor R2. The alarm prompt circuit includes resistors R3 and R4, transistors Q1 and Q2, and a buzzer B1 connected via circuit board wiring. One end of the first resistor R3 is connected to the base of the first transistor Q1, the collector of the first transistor Q1 is connected to one end of the second resistor R4 and the second transistor Q2, the collector of the second transistor Q2 is connected to the negative power input end of the buzzer B1, the positive power input end of the buzzer B1 is connected to the other end of the second resistor R4, and the emitters of the two transistors Q1 and Q2 are connected.

[0017] Figure 1 , 2 As shown, the power input terminals 1 and 2 of the power supply mechanism W1 are connected to the two poles of the AC 220V power supply through wires, the power output terminals 3 and 4 of the power supply mechanism W1 are connected to the negative pole of the power input terminal capacitor C1 of the detection mechanism, the positive pole of the power input terminal buzzer B1 of the alarm prompt circuit, and the emitter of the transistor Q2 through wires, and one end of the signal output terminal resistor R1 of the detection mechanism is connected to the other end of the signal input terminal resistor R3 of the alarm prompt circuit through wires. The power input terminal of the motor reduction device M1 is connected in series with a power switch S1 (the handle is located outside the component box) and the two poles of the AC 22V power supply through wires.

[0018] Figure 1 , 2As shown, the present invention is based on an electric drive reel body 1. In the application, the cable reel driven by the motor reduction mechanism of the electric drive reel body 1 rotates clockwise or counterclockwise to reel in or unwind the cable. The electric guide mechanism 101 of the electric drive reel body 1 moves back and forth under the control of the electric drive reel supporting control system, 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. After the 220V AC power supply enters the power input end of the power supply mechanism W1, the 3rd and 4th pins of the power supply mechanism W1 output a DC 12V power supply to enter the power input end of the detection mechanism and the alarm prompt circuit, and the above circuits and mechanisms are powered on. After the staff turns on the power switch S1 (the handle is located on the front outer side of the component box), the motor reduction device M1 is powered on and its shaft drives the fixed plate 2 to rotate clockwise. The staff visually observes that the fixed plate 2 drives the electric drive mechanism body 1 to rotate in place and then turns off the power switch. In actual situations, when the motor reduction device M1 is powered on and its shaft rotates normally, the magnet 62 rotates synchronously. In this way, the coil M generates electrical energy due to the magnetic cutting effect and enters the power input end of the bridge stack W2. The DC power output from pins 3 and 4 of the bridge stack W2 is filtered by capacitor C1 and enters one end of resistor R1 (resistors R1 and R2 divide the voltage, and resistor R3 reduces the voltage and limits the current). The base of transistor Q1 is turned on by the power input, and the collector outputs a low level and enters the base of transistor Q2. The transistor Q2 is cut off and the buzzer B1 does not sound, indicating that the operation is normal. In actual situations, when the motor deceleration device M1 is powered on and its shaft does not rotate due to various abnormalities, since the magnet 62 is no longer rotating synchronously, the coil M will no longer generate electrical energy to enter the power input end of the bridge stack W2 due to the lack of magnetic cutting effect. The 3rd and 4th pins of the bridge stack W2 will no longer output DC power and enter the resistor R1 through the capacitor C1 filtering. The base of the transistor Q1 has no power input and the collector will no longer output a low level to enter the base of the transistor Q2. The base of the transistor Q2 is turned on by the resistor R4 to obtain a suitable forward bias voltage and its collector outputs a low level to enter the negative power input end of the buzzer B1. The buzzer B1 is powered on and sounds to remind the staff that the motor deceleration device M1 has a fault and needs to be maintained in time, ensuring the stable operation of the entire equipment. Through the joint action of all the above mechanisms, in the application, the staff can control the electric drive reel body to rotate 360 ​​degrees in the equipment cab to facilitate the reeling and unreeling of the cable; when the motor deceleration device is abnormal, it can sound in time to remind the staff to repair, ensuring the overall stable and reliable operation of the equipment. Figure 2As shown, transistors Q1 and Q2 are NPN transistors of model 9013; power supply mechanism W1 is a finished product of AC 220V to DC 12V switching power supply module; the resistance values ​​of resistors R1, R2, R3, and R4 are 10K, 2K, 100K, and 200K respectively; buzzer B1 is a finished product of active continuous sound buzzer alarm of model MF12V; capacitor C1 is an electrolytic capacitor of model 470UF / 25V; bridge accumulator W2 model is KBP301; motor reduction device W1 is a finished product of coaxial motor gear reducer of AC 220V and power 3KW.
