When working, the staff controls the drum of the electric winch to rotate counterclockwise or clockwise, and then reel in or unreel the wire rope, and the sling (hook) drives the basket at the lower end to rise or fall in height to meet the needs of lifting goods, etc.
[0003] Although the existing electric hanging baskets have met the needs of hoisting work to a certain extent, due to structural limitations, there are still the following technical problems that need to be improved. First: Specifically, the hoisting hook used in it cannot change direction. If the hoisting angles of the hook and the goods are different when hoisting goods, the hoisting personnel will need to manually rotate the hook with a heavier weight to align it with the goods hoisting position. The above method will bring inconvenience to the staff and is not conducive to improving work efficiency. Second: It does not have a safety reminder function. During the hoisting of goods, if the distance between the goods and the person is too close, there is a possibility that the goods are too close to other staff members, causing them to suffer personal injury. In summary, it is very necessary to provide a hanging basket sling that can change the direction of the hook wirelessly and can serve as a good safety reminder for people who are too close.

[0015] Figure 1 , 2 As shown, the driven gear 2 is located between the two bearings and meshes with the driving gear 4, and the number of teeth of the driving gear 4 is less than the number of teeth of the driven gear 2. The wireless receiving circuit includes a wireless receiving circuit module W3 and relays K1 and K2 connected via a circuit board, the positive control power input terminals of the relays K1 and K2 are connected to the positive power input terminal 1 pin of the wireless receiving circuit module W3, the two power output terminals 3 and 4 of the wireless receiving circuit module W3 are respectively connected to the positive power input terminals of the two relays K1 and K2, and the negative power input terminal of the wireless receiving circuit W3 is connected to the negative power input terminals of K1 and K2 and the negative control power input terminal.

[0017] Figure 1 , 2As shown, the new type of cooperative electric hanging basket is used based on the sling body 1. In application, an electric winch (not shown) is installed at a high place on the building frame, and one end of the wire rope is fixed to the side end of the frame. The wire rope goes from the lower left end wheel groove and the lower right end wheel groove of the pulley 104 at the upper end of the sling body 1 (located on the hoisted goods) and is upwardly bypassed and fixedly installed together with the drum of the electric winch. When working, the staff controls the drum of the electric winch to rotate clockwise or counterclockwise, and then reel in or unreel the wire rope. The sling (hook) 1 drives the basket at the lower end to rise or fall in height to meet the needs of lifting goods, etc. (the goods are located in the basket or hooked on the hook). After the 220V AC power supply enters the power input terminal of the power module W1, the 3rd and 4th pins of the power module W1 output a stable DC 12V power supply that enters the power input terminal of the wireless receiving circuit and the prompt circuit, and the above circuit is powered on. When hoisting goods (the goods are on the hook or in the hanging basket), the worker presses the first button S1 or the second button S2 of the portable wireless remote control mechanism W4 with his finger, and the wireless remote control mechanism W4 transmits the first or second wireless closing signal. After the wireless receiving circuit module W3 receives it, its 3rd or 4th pin will output a high level, and the relay K1 or K2 will be energized to attract its control power input terminal and the normally open contact terminal to close, and then, the positive and negative or negative and positive power input terminals of the motor reduction mechanism M will be energized. After the positive and negative power input terminals of the motor reduction mechanism M are energized, its rotating shaft drives the driving gear 3 to reduce speed and drive the driven gear 2 to rotate clockwise to the corresponding angle, which is convenient for lifting goods. After the negative and positive power input terminals of the motor reduction mechanism M are energized, its rotating shaft drives the driving gear 3 to reduce speed and drive the driven gear 2 to rotate counterclockwise to the corresponding angle, which is convenient for lifting goods (after being in place, the staff presses the first button S1 or the second button S2 of the portable wireless remote control mechanism W4 with their fingers again, and the wireless remote control mechanism W4 will emit the first or second wireless open-circuit signal. After the wireless receiving circuit module W3 receives it, its 3rd or 4th foot will stop outputting a high level, and then, the relay K1 or K2 loses power and is no longer attracted, and the motor reduction mechanism M1 no longer drives the hook to rotate).
[0018] Figure 1 , 2As shown, when working, when no one approaches the spreader body 1 (1 meter interval), when no one approaches the front end of the detection surface of the pyroelectric detection module W5, the 3rd pin of the pyroelectric detection module W5 does not output a high level, and the buzzer B does not sound, indicating that no one is approaching the spreader body 1 within a safe distance; when someone approaches the spreader body 1 (for example, less than 1 meter), when someone approaches the front end of the detection surface of the pyroelectric detection module W5, the 3rd pin of the pyroelectric detection module W5 outputs a high level, and the high level enters the base of the transistor Q1 through the voltage reduction and current limiting of the resistor R1, and the transistor Q1 conducts and outputs a low level to the negative power input terminal of the buzzer B, and the buzzer B is powered and sounds, indicating that someone is approaching the spreader body 1 within a safe distance. Through the above, in this new application, the staff can conveniently adjust the hook to any angle through wireless methods such as wireless remote control mechanism and wireless receiving circuit, which brings convenience to the staff to hook the goods and correspondingly improves the work efficiency. During the lifting process, if someone is too close to the lifting device and there is a safety hazard, the warning circuit can promptly sound and light alarms to remind relevant personnel to pay attention to safety, thus minimizing the chance of personal accidents. Figure 2 As shown, the resistance value of resistor R1 is 47K; transistor Q1 is an NPN transistor of model 9013; buzzer B is an active continuous sound buzzer alarm of model MF12V; relays K1 and K2 are DC12V; power module W1 is an AC 220V to DC 12V power module; wireless transmitting mechanism W4 and wireless receiving circuit module W3 are wireless transmitting and receiving circuit modules of model WF200, and the wireless signal receiving and sending distance is 200 meters (consistent with the principle of vehicle wireless transmitting and receiving modules); motor reduction mechanism M is a coaxial motor gear reducer of power 50W; pyroelectric detection module W5 is a human infrared sensing electronic module of model HC-SR501, which has two power input terminals and a signal output terminal. When there is an active human body signal on the detection surface, the signal output terminal outputs power, otherwise it does not output. There is a distance adjustment knob in the shell. Adjust the detection distance to the left to make it farther and to the right to make it closer. It is appropriate to adjust it to 1 meter in this embodiment.
