Description
Technical Field
[0001] The utility model relates to the technical field of aerial work equipment, in particular to a hanging basket with a novel water supply mechanism. 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, and to install components and maintain mechanical equipment at a high height, two working wire ropes are generally set vertically downward from the upper end of the work point. The two working wire ropes pass through the wheel grooves of the pulleys on both sides of the high fixed frame and go toward the lower end (some fixed frames are installed at the lower end of the support frame that can be displaced laterally, and the fixed frame drives the basket frame at the lower end to move left or right along the support frame, increasing the working range). Then the outer ends on both sides of the lower end of each wire rope are fixedly connected to the outer ends of the basket, and the inner side of the lower end of each wire rope is connected to the reel of one of the electric winches on both sides of the basket. When the staff controls the rotation direction of the motor of the electric winch, the reduction gear of the electric winch will reduce the motor power to increase the torque and then drive the reel to rotate clockwise or counterclockwise, reel in or unreel the wire rope, and then the basket rises or falls in height. After the basket stops moving, the staff can work at the corresponding height.
[0003] The existing electric hanging baskets specially used for cleaning glass and walls of high-rise buildings are generally equipped with hoses for cleaning purposes. The upper end of the hose is connected to the water pipe in the building, and the lower end is located in the basket. When cleaning, the staff opens the valve connected to the lower end of the hose, so that the glass or wall can be easily cleaned with tap water. Although the above method meets the cleaning needs of the wall or glass to a certain extent, it is limited by the structure and still has the following technical problems to be solved. First, the length of the rubber hose is relatively long, and the space in the basket of the electric hanging basket is limited. Such a long hose cannot be effectively stored in the basket, which will occupy the corresponding working space in the hanging basket, and storing the hose together will also bring certain inconveniences to the staff. Second, when the pressure of the tap water pipe is low due to various reasons, it will not be able to meet the pressure requirements for flushing the wall or glass, which will have an adverse effect on the cleaning work. In summary, it is particularly necessary to provide an electric hanging basket that can effectively store the hose and can increase the water pressure when the water pressure is too low.

[0017] Figure 1 , 2As shown, the solenoid valves DC, DC1 and DC2 are normally closed valve core solenoid valves; the pressure switch D1 is a finished product of a normally closed contact type electric contact pressure switch. Water seal rings (sealing function) are respectively installed on the left and right sides of the bearing of the bearing seat 41 and the inner and outer rings of the bearing A46.

[0018] Figure 1 , 2As shown, the new type is used in conjunction with the electric hanging basket body 1. 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 end of the working point (the wire ropes are passed downward through the wheel groove of the pulley), and the lower end of the working wire rope 102 is fixed together with the winch reel at the left and right sides of the basket of the electric hanging basket. During operation, the reel of the electric winch 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 work (the above is an existing mature technology, and this application will not be repeated). After the AC power enters the power input terminal of the power module W1, the 3rd and 4th pins of the power module A1 output a stable DC 24V power supply and enter the power switch S1, S, S2, S3 and the power input terminal of the detection circuit. In actual application, after the staff turns on the power switches S and S3, the solenoid valves DC1 and DC2 will be energized to open the valve cores, so that tap water will enter the reel 42 through the hose 2, and then enter the flushing pipe 48 from the connecting pipe 44 in the fixed tube 45 at the left end. The staff can hold the flushing pipe 48 to flush the walls and glass, etc. When the basket of the electric hanging basket body 1 rises or falls in height and the hose 2 needs to be wound or unwound, the staff turns the handle of the power switch S1 to the left or right, and the 1st and 2nd feet and the 3rd and 4th feet or the 5th and 6th feet of the power switch S1 are connected respectively, and the positive and negative or negative and positive power input terminals of the motor reduction device M1 are energized; after the positive and negative power input terminals of the motor reduction device M1 are energized, its rotating shaft drives the reel 42 to rotate clockwise through the right end connecting pipe 44 to reel in the hose 2 (turn off the power switch S1 after it is in place), and the negative and positive power input terminals of the motor reduction device M1 are energized. After the input end is energized, its rotating shaft drives the reel 42 to unwind the hose 2 counterclockwise via the right end connecting pipe 44 (turn off the power switch S1 after it is in place); through the above, the new type can conveniently control the reel to reel in or unwind the hose (when the rotating shaft of the motor reduction device M1 drives the reel to rotate, the connecting pipes on both sides of the reel rotate along the left end bearing seat and the right end bearing seat and the right end bearing A, and the water inlet pipe 47 does not rotate, ensuring that the tap water will enter the left and right end connecting pipes 44 through the rotating hose 2, the water outlet pipe 421, and the reel 42, and enter the flushing pipe from the left end water inlet pipe).In the present invention, when the tap water pressure is insufficient, the staff fills the drum with water, turns off the power switch S, turns on the power switches AS2 and S3 (turns off the power switch S1), and the solenoid valve DC2 loses power and the valve core is closed. When the water pressure in the drum is lower than a certain level (for example, lower than 1Mpa), the internal contact of the pressure switch D1 is closed, so that the 24V power supply will enter the base of the transistor Q1 through the resistor R1 for voltage reduction and current limiting. The transistor Q1 is turned on and the collector outputs a low level and enters the negative power input terminal of the relay K1. The relay K1 is energized and its control power input terminal and the normally open contact terminal are closed. In this way, the high-pressure compressed air output by the air compressor storage tank is It will enter the drum and increase the water pressure in the drum, so that the tap water after pressurization in the drum can play a better cleaning effect after flushing on the wall or glass; when the water pressure in the drum is higher than a certain level (for example, higher than 1Mpa), the internal contact of the pressure switch D1 is open, so that the 24V power supply no longer enters the base of the transistor Q1 through the resistor R1, and the collector of the transistor Q1 is cut off and no longer outputs a low level to enter the negative power input terminal of the relay K1. The relay K1 loses power and no longer attracts its control power input terminal and the normally open contact terminal. In this way, the high-pressure compressed air output by the air compressor air tank no longer enters the drum, and the water pressure in the drum is at a suitable pressure. After the water in the drum is used up, the staff can turn on the power switch S again, so that the tap water will enter the drum again, which is exactly the same as the above operation process. When the tap water pressure is too low, the tap water can be pressurized to meet the water pressure requirements of high water pressure cleaning walls or glass.
[0019] Figure 1 , 2 As shown above, in the new application, the rubber hose can be retracted and released through the electric reel mechanism through the control of the power switch, so that the hose will not be placed in a scattered manner in the basket, the space in the basket is more compact and beautiful, and it is convenient for the staff to retract and release the hose; when the tap water pressure is too low, the cleaning water in the reel can be pressurized to increase the cleaning water pressure, which can relatively achieve better wall and glass cleaning effects. Figure 2 Among them, the resistance value of resistor R1 is 1K; transistor Q1 is an NPN transistor of model 9013; relay K1 model is DC24V; power module W1 is an AC 220V to DC 24V power module; motor reduction device M1 is a coaxial motor gear reducer product with a power of 200W; solenoid valves DC, DC1, and DC2 are normally closed valve core solenoid valves with a power of 2W.
