Description

Technical Field

[0001] The utility model relates to the technical field of aerial work equipment, in particular to an automatic hanging basket. Background Art

[0002] The electric hanging basket is a commonly used work tool, and its main structure includes an electric winch and a basket frame. When the electric hanging basket is used to install equipment or clean glass and walls in high-rise buildings, or to install components and maintain mechanical equipment at a high altitude, two working wire ropes are generally set vertically downward from the upper end of the work point. The lower end of the working wire rope is fixed to the winch reel on the left and right sides of the basket of the electric hanging basket. During operation, the electric winch reel can reel in or unreel the wire rope to adjust the height of the basket, so that the operator can work at the required height work point.

[0003] Although the existing electric hanging baskets meet the work needs to a certain extent, due to structural limitations, there are still the following technical problems that need to be solved urgently. Specifically, the rise and fall of the electric hanging basket needs to be controlled by the staff inside or outside the basket. Affected by various factors, the winch on the left or right side fails, and the speeds of the two sets of winding wire ropes are inconsistent (in actual situations, the outer diameter of the winch's reel will become larger after the wire rope is wound, and the wire rope cannot be wound horizontally on the reel in the same position. It is easy for the outer diameters of the two sets of winches to be inconsistent after the wire rope is wound, which in turn causes the speeds of the two sets of winches to be inconsistent). It is possible that one end of the basket of the hanging basket will have relatively more wire rope wound, which will cause the height of the basket on that side to become higher and the basket to tilt as a whole, posing a certain threat to the safety of the staff inside the basket. In summary, it is particularly necessary to provide a hanging basket that can effectively monitor whether the basket is tilted and can automatically adjust the horizontality. Utility Model Content

[0004] In order to overcome the drawbacks of the existing electric hanging basket due to structural limitations as described in the background technology, the utility model provides an automatic hanging basket based on the hanging basket body, which can monitor in real time whether the basket is tilted left or right under the joint action of relevant mechanisms during application, and can promptly remind the staff in the basket to pay attention to safety when tilted, and can automatically adjust the level of the basket, thereby achieving a good safety effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Furthermore, two side ends of the counterweight block are located between the force-bearing surfaces of the two sets of pressure sensors, and there is a distance between the counterweight block and the force-bearing surfaces of the two sets of pressure sensors.

The utility model can achieve good safety effects and has good application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 , 2As shown in , the left and right side ends of the metal spherical counterweight 5 are located between the force-bearing surfaces of the two sets of pressure sensors D3, and the distance between the metal spherical counterweight 5 and the force-bearing surfaces of the two sets of pressure sensors D3 is . Each set of tilt detection circuits includes resistors R1, R2, R3, R4, and an operational amplifier D2 connected by circuit board wiring. One end of the first resistor R1 is connected to the positive power input terminal 8 pin of the operational amplifier D2, the other end of the first resistor R1 is connected to one end of the second resistor R2 and the in-phase input terminal 3 pin of the operational amplifier D2, one end of the third resistor R3 is connected to one end of the fourth resistor R4 and the reverse input terminal 2 pin of the operational amplifier D2, and the other end of the fourth resistor R4, the other end of the second resistor R2 and the negative power input terminal 2 pin of the operational amplifier D2 are connected. Each control circuit includes a resistor R5 and a transistor Q1, a relay K1, and a buzzer B connected by circuit board wiring. The positive power input terminal of the relay K1 is connected to the collector of the transistor Q1 and the positive power input terminal of the buzzer B. One end of the resistor R5 is connected to the base of the transistor Q1. The negative power input terminal of the relay K1 is connected to the negative power input terminal of the buzzer B. The two control power input terminals of the relay K1 of the two control circuits and the power input terminals 1 and 2 of the power module D1 are connected to the two poles of the AC 220V power supply through wires, respectively. The power output terminals 3 and 4 of the power module D1 are connected in series through the power switch S1 and the power input terminals 8 and 4 of the op amp D2 of the two tilt detection circuits, the power input terminals of the two control circuits, the emitters of the transistor Q1, the negative power input terminals of the relay K1, and the power input terminals 1 and 2 of the two pressure sensors D3 are connected through wires. The signal output terminal 3 pins of the two pressure sensors D3 and the other ends of the signal input terminal resistors R3 of the two tilt detection circuits are connected via wires. The signal output terminal op amp D2 of the two tilt detection circuits and the other ends of the signal input terminal resistors R5 of the two control circuits are connected via wires. The two normally open contact terminals of the power output terminal relay K1 of the two control circuits and the two power input terminals of the motor M of the electric hoist at the left and right sides of the basket of the electric hanging basket body are connected via wires (the two normally open contact terminals of the relay K1 and the main power input terminal of the motor M and one of the terminals of the running capacitor C of the motor are connected via wires. After the main power input terminal of the motor M and one of the terminals of the running capacitor C of the motor are energized, the motor will drive the reel to rotate clockwise to reel in the wire rope through the reduction gear of the electric hoist. After the main power input terminal of the motor M and the other terminal of the running capacitor C of the motor are energized, the motor will drive the reel to rotate counterclockwise to unwind the wire rope through the reduction gear of the electric hoist).

[0016] Figure 1 , 2As shown, the utility model is based on the electric hanging basket body. When the electric hanging basket body 1 is used for installing equipment in high-rise buildings or cleaning glass and walls, and for installing components and maintaining mechanical equipment at a high height, two working wire ropes are vertically arranged downward at the upper height of the working point. The lower end of the working wire rope 102 is fixed together with the hoisting machine reel at the left and right sides of the basket of the electric hanging basket. During operation, the reel of the electric hoisting machine can reel in the wire rope or unwind the wire rope to achieve the height adjustment of the basket 101, and then the operator can be located in the basket at the required height working point to operate (the above is the existing mature technology, and this application will not be repeated). After the AC power supply enters the power input end of the power module D1, the 3rd and 4th feet of the power module D1 output a stable DC 12V power supply to enter the power input end of the two sets of tilt detection mechanisms, the tilt detection circuit 2, and the control circuit 3 (under the premise that the power switch S1 is turned on, the power switch is only turned on when working and the staff does not actively control the hanging basket body to go up or down). In actual applications, when the basket 101 does not tilt left or right, the distance between the metal spherical counterweight 5 and the force-bearing surfaces of the two sets of pressure sensors D3 is such that the force-bearing surface of the left or right set of pressure sensors D3 is not subjected to any force, and the voltage signal outputted from pin 3 thereof is relatively low. This voltage signal is divided by resistors R3 and R4 (less than 6V) and enters pin 2 of the operational amplifier D2, which is lower than the voltage of the 12V power supply that enters pin 3 of the operational amplifier D2 (about 6V) after being divided by resistors R1 and R2. Pin 1 of the operational amplifier D2 outputs a high level, and then the relay K1 will not be energized and energized, and accordingly, the motor of the electric winch on the left or right side of the basket will not be energized and work, and the basket 101 will maintain an appropriate level.When the basket 101 tilts left or right, the metal spherical weight 5 contacts the force-bearing surface of the pressure sensor D3 at the left or right end. The force-bearing surface of a set of pressure sensors D3 at the left or right end is subjected to the force, and the voltage signal outputted by its pin 3 is relatively high. This voltage signal is divided by resistors R3 and R4 (higher than 6V) and enters the pin 2 of the operational amplifier D2, which is higher than the voltage of the 12V power supply that enters the pin 3 of the operational amplifier D2 after being divided by resistors R1 and R2 (about 6V). The pin 1 of the operational amplifier D2 outputs a low level, which is reduced and limited by resistor R5 and enters the base of the transistor Q1. The transistor Q1 is turned on and the collector outputs a low level, which enters the positive power input terminal of the relay K1. Then the relay K1 will be energized. The control power input terminal and the normally open contact terminal are closed by attracting, and accordingly, the motor of the electric winch on the left or right side of the basket will be powered on (two power input terminals are powered on). After the motor M of the electric winch on the side where the height of the basket 101 is lowered is powered on, the reel of the electric winch drives the winding wire rope, so that the height of the side where the height of the basket is lowered will gradually rise; after the electric winch on the left or right side of the basket is powered on to make the height of the basket higher and the horizontality of the left and right sides close to the same, the metal spherical counterweight 5 no longer contacts the force-bearing surface of the pressure sensor D3 on the left or right side, so that the electric winch on the left or right side is no longer powered on, achieving the effect of automatically adjusting the horizontality of the basket. When the electric winch on the left or right side of the basket is powered on, that is, when the transistor Q1 is turned on, the buzzer B will be powered on to sound, intuitively reminding the staff in the basket to pay attention to safety, and the basket will automatically adjust its horizontality, which can achieve a good safety effect. The model of operational amplifier D2 is UA741; the resistance values ​​of resistors R1, R2, R3, R4, and R5 are 10K, 10K, 4K, 3.8K, and 1K respectively; transistor Q1 is a PNP transistor of model 9012; buzzer B is a finished active continuous sound buzzer alarm of model MF12V; the model of relay K1 is DC12V; the power supply module D1 is an AC 220V to DC 12V power supply module; the model of capacitor C is a 14μF / 400V non-polar electrolytic capacitor; the pressure sensor D3 is a finished micro weighing sensor of model ZNHM-I, which has two power input terminals and one signal output terminal. The greater the gravity force on the force-bearing surface of the pressure sensor, the greater the voltage signal output by the signal output terminal, and vice versa.
