Description

Technical Field

[0001] This patent relates to the field of suction cup technology, specifically a hanging suction cup for glass curtain wall installation. Background Technology

[0002] When installing glass curtain walls, the glass needs to be hoisted to the desired installation height using hoisting equipment. The suction end of most hoisting equipment is a vacuum suction cup. Existing vacuum suction cups are composed of rubber covers. To increase the external compressive strength of the rubber covers, a rigid shell is installed on the outside of the rubber covers. However, the rubber covers and the shell are mostly fixed with adhesive, making it inconvenient to disassemble them when replacing the rubber covers. Therefore, we propose a hoisting suction cup for glass curtain wall installation. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this patent is to provide a lifting suction cup for glass curtain wall installation. This patent involves a housing fitted over a rubber cover, with a pressure plate pressed against the inner wall of the rubber cover. A threaded rod is installed on the outer side of the pressure plate, and the end of the threaded rod can pass through the rubber cover, the housing, and the horizontal plate to be fixed with a nut. This method not only facilitates the fixing of the rubber cover and the housing, but also fixes the two to the horizontal plate (which is the main frame of the suction cup), making it easy to assemble and disassemble the rubber cover.

[0004] The technical solution adopted by this patent to solve its technical problem is: a suction cup for installing glass curtain walls, including a suction cup body, with horizontal plates fixedly installed at both the upper and lower ends of the right side surface of the suction cup body, a lifting ring fixedly installed at the top of the upper horizontal plate, and a vacuum system fixedly connected to the right end of the suction cup body.

[0005] The suction cup body includes a suction cup surface and a pressure plate. A rubber cover is integrally formed on the right side of the suction cup surface. A housing is fitted on the outer side of the rubber cover. Positioning grooves are provided at both the upper and lower ends of the outer side of the housing. The internal shape of the positioning groove matches the shape of the left end of the horizontal plate. The left end of the horizontal plate is inserted into the positioning groove. An inclined plate is integrally formed on the outer side of the horizontal plate. The outer side of the pressure plate is tightly fitted to the inner side of the rubber cover. A threaded rod is integrally formed in the middle of the outer side of the pressure plate. The end of the threaded rod passes through the rubber cover, the housing, the horizontal plate, and the inclined plate in sequence and is screwed with a nut.

[0006] Furthermore, it also includes a control system, which comprises a control box, a PLC controller, sensors, and an operation panel. The sensors include a pressure sensor, a displacement sensor, and a tilt sensor. The pressure sensor is installed inside the suction cup body, and the displacement sensor and tilt sensor are respectively installed on the two horizontal plates.

[0007] Furthermore, the vacuum system includes a vacuum pipe, a vacuum storage tank, and a vacuum pump. The left end of the vacuum pipe is fixedly connected to the right end of the suction cup body, the right end of the vacuum pipe is connected to the vacuum storage tank, the vacuum storage tank is connected to the vacuum pump, and an electromagnetic valve is provided on the vacuum pipe, the electromagnetic valve including an inlet valve and an exhaust valve.

[0008] Furthermore, a pressure sensor is installed on the vacuum storage tank.

[0009] Furthermore, a shackle is installed on the lifting ring.

[0016] The present patent is further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the patent. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art can make various alterations or modifications to this patent, and these equivalent forms also fall within the scope defined by the appended claims.

[0017] See Figure 1 , Figure 2 and Figure 3This is a schematic diagram of the structure of this patent. A suction cup for installing a glass curtain wall includes a suction cup body 1. Horizontal plates 2 are fixedly installed at both the upper and lower ends of the right side surface of the suction cup body 1. A lifting ring 3 is fixedly installed on the top of the upper horizontal plate 2. A vacuum system 4 is fixedly connected to the right end of the suction cup body 1.

[0018] The suction cup body 1 includes a suction cup surface 5 and a pressure plate 11. A rubber cover 6 is integrally formed on the right side of the suction cup surface 5. A housing 7 is fitted on the outer side of the rubber cover 6. Positioning grooves 8 are provided at both the upper and lower ends of the outer side of the housing 7. The internal shape of the positioning groove 8 matches the shape of the left end of the horizontal plate 2. The left end of the horizontal plate 2 is inserted into the positioning groove 8. An inclined plate 10 is integrally formed on the outer side of the horizontal plate 2. The outer side of the pressure plate 11 is tightly attached to the inner side of the rubber cover 6. A threaded rod is integrally formed in the middle of the outer side of the pressure plate 11. The end of the threaded rod passes through the rubber cover 6, the housing 7, the horizontal plate 2 and the inclined plate 10 in sequence and is screwed with a nut 9.

[0019] The threaded rod is made of M8×60 stainless steel with a thread pitch of 1.25mm. Nut 9 is a matching M8 lock nut with a tightening torque set at 12-15N・m to ensure a secure connection.

[0020] like Figure 2 As shown, the housing 7 is made of a rigid material, and its internal contour matches the external contour of the rubber cover 6.

[0021] Specifically, it also includes a control system, which consists of a control box, a PLC controller, sensors and an operation panel. The sensors include a pressure sensor, a displacement sensor 17 and an tilt sensor 18. The pressure sensor is installed inside the suction cup body 1, and the displacement sensor 17 and the tilt sensor 18 are respectively installed on two horizontal plates 2.

[0022] The control box is installed in the operator's room of the hoisting equipment for convenient control and monitoring by the operator. The PLC controller, as the core of the control system, receives data signals from various sensors and controls the vacuum system and safety auxiliary systems according to preset programs.

[0023] The sensors include a pressure sensor, a displacement sensor, and a tilt sensor. The pressure sensor monitors the pressure inside the suction cup body 1; the displacement sensor 17 monitors the displacement of the suction cup in real time to prevent the suction cup from shifting during the adsorption process; the tilt sensor 18 monitors the tilt angle of the suction cup during the hoisting process, and when the tilt angle exceeds the set value, it issues an alarm signal and takes corresponding adjustment measures.

[0024] The pressure sensor and pressure sensor 16 inside the suction cup body 1 both use Honeywell ASDX series, model ASDX-50KPA, with a range of 0 - 50kPa, accuracy of ±0.25% FS, and response time of <1ms, which can accurately monitor the pressure inside the suction cup and the air tank in real time.

[0025] The displacement sensor 17 uses an OMRON E2E series proximity sensor, model E2E-X10D1-M1J, with a detection distance of 10mm and a repeatability of ±0.01mm, which can effectively monitor the displacement of the suction cup.

[0026] The tilt sensor 18 uses the TE Connectivity ADIS16505, with a measurement range of ±60° and a resolution of 0.001°, which can accurately sense the tilt angle of the suction cup.

[0027] Pressure sensor: When the pressure inside the suction cup is lower than -80kPa, a level one alarm is triggered; when it is lower than -70kPa, the hoisting operation is stopped and air replenishment is started; when the pressure in the air storage tank is lower than -90kPa, the vacuum pump is automatically started to replenish air.

[0028] Displacement sensor 17: An alarm is triggered when the suction cup displacement exceeds 5mm, and the hoisting is forcibly stopped when it exceeds 8mm.

[0029] Tilt sensor 18: An alarm is triggered when the tilt angle exceeds 5°, and the vacuum system is cut off when the tilt angle exceeds 8° to prevent the glass from falling.

[0030] The control panel is located on the control box and has a simple and clear interface. Operators can start and stop the vacuum pump, control the opening and closing of the vacuum valve, and view various monitoring data through the control panel. The control panel is also equipped with an emergency stop button, which can immediately stop all operations in case of emergency to ensure construction safety.

[0031] Specifically, the vacuum system 4 includes a vacuum pipe 13, a vacuum storage tank 14, and a vacuum pump 15. The left end of the vacuum pipe 13 is fixedly connected to the right end of the suction cup body 1, and the right end of the vacuum pipe 13 is connected to the vacuum storage tank 14. The vacuum storage tank 14 is connected to the vacuum pump 15. The vacuum pipe 13 is equipped with an electromagnetic valve, which includes an inlet valve and an exhaust valve.

[0032] Vacuum pump 15 is a high-performance rotary vane vacuum pump. This type of vacuum pump has the advantages of fast pumping speed, high vacuum degree and stable operation. It can extract the air in the suction cup in a short time to form a vacuum environment. The power of the vacuum pump is reasonably configured according to the specifications and number of suction cups to ensure that the required vacuum degree can be achieved quickly.

[0033] Vacuum pump 15 uses a Busch R5 series rotary vane vacuum pump, model R5-250, with a pumping speed of 250 m³ / h and an ultimate vacuum of 0.5 mbar, suitable for medium and large suction cup assemblies; for small suction cups, a Becker VT4.4 series pump, model VT4.4-0.8, with a pumping speed of 8 m³ / h and an ultimate vacuum of 10 mbar can be selected.

[0034] The vacuum storage tank 14 is made of high-strength stainless steel and is used to store a certain amount of vacuum. When the vacuum pump stops working briefly or an emergency occurs, it can continuously provide vacuum support for the suction cup to ensure the stability of adsorption. The storage tank is equipped with a pressure sensor 16 to monitor the pressure inside the tank in real time. When the pressure is lower than the set value, the vacuum pump is automatically started to replenish the gas.

[0035] Vacuum pipe 13 uses high-pressure resistant and corrosion-resistant rubber hoses to connect the vacuum pump, vacuum storage tank and suction cup, ensuring the sealing and reliability of the vacuum system.

[0036] The electromagnetic valve includes an inlet valve and an exhaust valve. It uses electromagnetic control to achieve rapid opening and closing of the valve through a control system, and precisely controls the adsorption and release process of the suction cup.

[0037] Vacuuming process: Vacuum pump starts → Vacuum tank is evacuated → Inlet valve is opened (exhaust valve is closed) → Vacuum is transferred to suction cup through pipe → Suction cup adsorbs glass.

[0038] Release process: Close the intake valve → Open the exhaust valve → Air enters the suction cup → Adsorption is released.

[0039] Specifically, a pressure sensor 16 is installed on the vacuum storage tank 14.

[0040] Specifically, a shackle 12 is installed on the lifting ring 3.

[0041] The lifting ring 3 and the chain of the lifting equipment are made of high-strength alloy steel. The lifting ring 3 is connected to the horizontal plate 2 by welding or bolting to ensure the connection is firm. The length of the chain can be adjusted according to the actual construction needs. The two ends of the chain are connected to the lifting ring 3 and the lifting hook of the lifting equipment respectively. The connection method adopts high-strength shackles for easy installation and disassembly.

[0042] Working principle: When replacing the rubber cover 6, simply remove the nut 9, then remove the pressure plate 11 from inside the rubber cover 6, then install the new rubber cover 6 inside the housing 7, and then complete the connection and assembly through the pressure plate 11.

[0043] The rubber cover 6 and the suction cup surface 5 are made of high-strength, wear-resistant and well-sealing nitrile rubber. Nitrile rubber has excellent oil resistance, wear resistance and aging resistance, and can be used for a long time in complex construction environments to ensure that the suction cup is tightly attached to the glass surface.

[0044] Nitrile rubber: Hardness 60 - 70 Shore A, tensile strength ≥18MPa, elongation at break ≥450%, temperature range -40℃ - 120℃, suitable for use in different environments.

[0045] The suction cup surface 5 is designed to be round or square. According to common glass curtain wall sizes, various specifications and models are available, such as round suction cups with diameters of 300mm and 500mm, and square suction cups with side lengths of 400mm×400mm and 600mm×600mm. The surface of the cup is set with evenly distributed anti-slip textures to further increase the friction with the glass surface and prevent the glass from sliding during the adsorption process.

[0046] It should be noted that the device structure and accompanying drawings of this patent mainly describe the principle of this patent. In terms of the technical aspects of this design principle, the setting of the device's power mechanism, power supply system and control system is not fully described. However, those skilled in the art who understand the principle of the above patent can clearly understand the specifics of its power mechanism, power supply system and control system.

[0047] This patent involves a housing fitted over the outside of a rubber cover, with a pressure plate pressed against the inner wall of the rubber cover. A threaded rod is installed on the outside of the pressure plate, and the end of the threaded rod can pass through the rubber cover, the housing, and the horizontal plate to be fixed with a nut. This method not only facilitates the fixing of the rubber cover and the housing, but also fixes the two to the horizontal plate (which is the main frame of the suction cup), making it easy to assemble and disassemble the rubber cover.
