Description

Technical Field

[0001] This invention relates to a component extraction device, and more particularly to a device for extracting irregularly shaped components from the outer surface of a curtain wall, belonging to the field of lifting machinery technology. Background Technology

[0002] Currently, curtain wall decoration is common on the exterior surface of buildings, and decorative curtain walls with unique shapes are also ubiquitous. As a result, irregular shapes appear on the exterior surface of decorative curtain walls. Irregular exterior surface components are usually called irregular components.

[0003] In existing technologies, the installation of curtain walls, whether standard or non-standard, involves manually tying components with ropes and then using overhead cranes or tower cranes to lift them to their designated positions. When installing irregularly shaped components with unique exterior surfaces, the special shape makes it difficult to ensure a stable and reliable lift from the ground to the installation location, often taking a considerable amount of time and significantly increasing the difficulty of rapid installation. Furthermore, while clamping methods can be used for lifting and moving, the clamping mechanism obstructs the direct contact between the curtain wall and the substrate at the installation position, necessitating the release of the curtain wall before installation, resulting in low work efficiency. Summary of the Invention

[0004] In view of the above-mentioned defects in the prior art, the present invention aims to provide a device for extracting irregularly shaped components on the outer surface of curtain walls, which solves the problem of rapid and stable lifting of irregularly shaped components of curtain walls, and at the same time (accurately lifts and places them in the installation position) improves the lifting and installation efficiency.

[0005] The technical solution of this invention is as follows: A device for extracting irregularly shaped components from the outer surface of a curtain wall, comprising a connecting plate, a crossbeam, and a suction cup hook mechanism. The crossbeam has three sections and is fixedly connected to the connecting plate. The suction cup hook mechanism is mounted on the crossbeam and includes a base, a vacuum suction cup, and a J-shaped support rod. The vacuum suction cup is fixedly connected to the base, and the J-shaped support rod is rotatably connected to the base. The rotation axis of the J-shaped support rod is higher than the suction surface of the vacuum suction cup. After the J-shaped support rod rotates away from the vacuum suction cup, its position is higher than the suction surface of the vacuum suction cup. When the J-shaped support rod rotates to be vertically aligned with the vacuum suction cup, it is used to clamp the irregularly shaped component. The base is provided with a driving device, which drives the J-shaped support rod to rotate.

[0006] In this invention, during the lifting process, the J-shaped support rod rotates and is positioned vertically relative to the vacuum suction cup. On the one hand, the irregularly shaped curtain wall component is picked up by vacuum, and on the other hand, the J-shaped support rod provides support on the bottom surface of the irregularly shaped curtain wall component, forming a stable clamp. During installation, by rotating the J-shaped support rod, the entire component is made higher than the suction surface of the vacuum suction cup, and the bottom surface of the irregularly shaped curtain wall component can be completely attached to the installation surface.

[0007] Furthermore, to improve the safety of the hoisting process and prevent external forces directly acting on the J-shaped support rod from causing it to rotate, the drive device includes a drive spindle mounted on the base. The top end of the J-shaped support rod is sleeved on the drive spindle. A first one-way clutch and a second one-way clutch are respectively provided on both sides of the J-shaped support rod. The first ring of the first one-way clutch is connected to the drive spindle, and a friction transmission mechanism is provided between the second ring of the first one-way clutch and the J-shaped support rod. The friction transmission mechanism includes a first disc, a friction elastic colloid, and a second disc arranged axially in sequence. Both the first disc and the second disc are rotatably connected to the drive spindle. The J-shaped support rod is fixedly connected to the first disc. A second ring of a one-way clutch is fixedly connected to the second disc body. The frictional elastic colloid has a rotating shaft arranged radially along the first disc body. The rotating cross section of the frictional elastic colloid has a long shaft larger than the distance between the first disc body and the second disc body and a short shaft smaller than the distance between the first disc body and the second disc body. The distance between the rotating shaft and the first disc body is greater than the distance between the rotating shaft and the second disc body. The drive main shaft drives the J-shaped support rod to rotate clockwise in one direction through the first one-way clutch and the friction transmission mechanism. The drive main shaft drives the J-shaped support rod to rotate counterclockwise in one direction through the second one-way clutch. The second disc body is provided with a ratchet and pawl mechanism, which locks the second disc body to rotate counterclockwise.

[0008] Furthermore, the friction transmission mechanism includes a retainer, which is disposed between the first disc and the second disc and is rotatably connected to the drive spindle. The retainer is provided with a plurality of radial support shafts, and the friction elastic colloid is rotatably disposed on the radial support shafts.

[0009] Furthermore, the triboelic colloid is an ellipsoid or an elliptical cylinder.

[0010] Furthermore, the frictional elastic colloid is provided in at least three parts and is equally distributed around the circumference of the cage.

[0011] Furthermore, the opposing surfaces of the first and second discs are provided with annular grooves to accommodate the rolling of the frictional elastic colloid. The major axis of the rotational cross-section of the frictional elastic colloid is greater than the distance between the bottoms of the annular grooves of the first and second discs, and the minor axis of the rotational cross-section of the frictional elastic colloid is smaller than the distance between the bottoms of the annular grooves of the first and second discs. The annular grooves increase the friction between the first and second discs and the frictional elastic colloid, thereby enhancing the locking force on the J-shaped support rod.

[0012] Furthermore, a motor is provided on the base, and the motor drives the drive spindle to rotate.

[0013] Furthermore, the hook end face of the J-shaped support rod is provided with a buffer rubber pad.

[0014] The advantages of this invention compared to the prior art are:

[0015] This invention uses vacuum suction cups mounted on three horizontal beams to adsorb curtain wall components. To prevent detachment, J-shaped supports are installed below each vacuum suction cup to support the lower surface, ensuring a firm grip on components of different shapes and curvatures and preventing them from falling off during lifting. Furthermore, the rotatable J-shaped supports, when retracted, are higher than the suction cups, allowing the vacuum suction cups to assist in the installation of the curtain wall components, improving convenience. A friction transmission mechanism is designed to change the transmission state through friction, allowing the drive shaft to directly rotate and drive the J-shaped supports. Simultaneously, the J-shaped supports can be locked when subjected to external forces not exceeding the driving force of the drive shaft, preventing accidental rotation during curtain wall component lifting. This eliminates the need for additional electrical control equipment, improving reliability. Attached Figure Description

[0023] The present invention will be further described below with reference to embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading this description, any modifications of this description in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0024] For examples, please refer to... Figures 1 to 5 As shown, this embodiment involves a device for extracting irregularly shaped components from the exterior surface of a curtain wall, including a connecting plate 1, a crossbeam 2, and a suction cup hook mechanism. The connecting plate 1 is used to connect with other mechanisms. Three crossbeams 2 are fixedly connected to the connecting plate 1 at three equally spaced circumferential positions via bolts. The ends of the crossbeams 2 are fixed to the connecting plate 1, and each crossbeam 2 has a suction cup hook mechanism at its front end. The crossbeams 2 are connected to the base 3 of the suction cup hook mechanism. The base 3 includes a connecting beam 301, which is a channel steel. The upper sidewall of the connecting beam 301 is connected to the bottom surface of the crossbeam 2 via bolts, and the lower sidewall of the connecting beam 301 is fixedly connected to the base 3 of the suction cup hook mechanism. More connecting holes than the upper sidewall of the connecting beam 301 are opened on the bottom surface of the crossbeam 2. By selecting the connecting holes, the installation position of the connecting beam 301 on the crossbeam 2 can be adjusted, thus adjusting the position of the suction cup hook mechanism on the crossbeam 2 to meet the specifications of the irregularly shaped components.

[0025] The suction cup support mechanism includes a base 3, a vacuum suction cup 4, and a J-shaped support rod 5, wherein the J-shaped support rod 5 is positioned closer to the front end of the crossbeam 2 than the vacuum suction cup 4. Please refer to... Figure 3 As shown, a suction cup end tube 6 is fixed on top of the vacuum suction cup 4. The suction cup end tube 6 is welded to the suction cup riser tube 7. The suction cup riser tube 7 is set vertically for connection with the vacuum transmitter. The suction cup riser tube 7 can be directly welded to the connecting beam 301 of the base 3, or a connecting piece 8 can be welded to the suction cup riser tube 7 and then fixed to the connecting beam 301 by bolts.

[0026] Please combine Figure 4 and Figure 5 As shown, the J-shaped support rod 5 is rotatably connected to the base 3. The rotation axis of the J-shaped support rod 5 is horizontally set and perpendicular to the crossbeam 2. The hook end face of the J-shaped support rod 5 is provided with a buffer rubber pad 9 to prevent damage to the components. The J-shaped support rod 5 has two main rotation positions. One position is when the hook of the J-shaped support rod 5 is directly below the vacuum suction cup 4 and opposite to the vacuum suction cup 4. The other position is when the rod of the J-shaped support rod 5 extends horizontally along the direction of the crossbeam 2. The rotation axis of the J-shaped support rod 5 is set higher than the suction surface of the vacuum suction cup 4 (the lower end face of the vacuum suction cup 4). That is, when the J-shaped support rod 5 rotates to the position of extending horizontally along the direction of the crossbeam 2, the whole is higher than the vacuum suction cup 4. When the J-shaped support rod 5 rotates to be vertically opposite the vacuum suction cup 4, it is used to clamp irregularly shaped components.

[0027] The specific connection method of the J-shaped support rod 5 is as follows: the driving device for driving the rotation of the J-shaped support rod 5 includes a drive spindle 10, which is connected to a motor 11 via a coupling. The motor 11 is fixed on the base 3. The drive spindle 10 is rotatably mounted on the base 3. The top end of the J-shaped support rod 5 is sleeved on the drive spindle 10. A first one-way clutch 12 and a second one-way clutch 13 are respectively provided on both sides of the J-shaped support rod 5. Both the first one-way clutch 12 and the second one-way clutch 13 include inner and outer rings, with the inner ring being the first ring and the outer ring being the second ring. The inner ring of the first one-way clutch 12 can drive the outer ring to rotate clockwise in one direction, and the inner ring of the second one-way clutch 13 can drive the outer ring to rotate counterclockwise in one direction. The first ring 1201 (i.e., inner ring) of the first one-way clutch 12 is splinedly connected to the drive spindle 10. The second ring 1202 of the first one-way clutch 12 is provided with a friction transmission mechanism between it and the J-shaped support rod 5. The first ring 1301 (i.e., inner ring) of the second one-way clutch 13 is splinedly connected to the drive spindle 10. The second ring 1302 of the second one-way clutch 13 is also splinedly connected to the top of the J-shaped support rod 5.

[0028] The friction transmission mechanism includes a first disc 14, a retainer 15, a friction elastic colloid 16, and a second disc 17 arranged axially in sequence. Both the first disc 14 and the second disc 17 are directly mounted on the drive shaft 10 and rotatably connected to it. The top of the J-shaped support rod 5 is fixedly connected to the first disc 14 (or via a spline connection). The second ring 1202 of the first one-way clutch 12 is fixedly connected to the second disc 17 (or via a spline connection). The retainer 15 is positioned between the first disc 14 and the second disc 17 and rotatably connected to the drive shaft 10. The retainer 15 is coaxially arranged with both the first disc 14 and the second disc 17. The retainer 15 has four radial support shafts 1501. The friction elastic colloid 16 is rotatably mounted on the radial support shafts 1501. The friction elastic colloid 16 is an ellipsoid or an elliptical cylinder. The rotational cross-section of the triboelic colloid 16 has a major axis greater than the distance between the first disc 14 and the second disc 17, and a minor axis less than or equal to the distance between the first disc 14 and the second disc 17. The distance between the rotational axis of the triboelic colloid 16 and the first disc 14 is greater than the distance between the rotational axis and the second disc 17. In a preferred embodiment, an annular groove 18 for accommodating the rolling of the triboelic colloid 16 is provided on the opposing surfaces of the first disc 14 and the second disc 17. The major axis of the rotational cross-section of the triboelic colloid 16 is greater than the distance between the bottoms of the annular grooves 18 of the first disc 14 and the second disc 17, and the minor axis of the rotational cross-section of the triboelic colloid 16 is less than or equal to the distance between the bottoms of the annular grooves 18 of the first disc 14 and the second disc 17. To achieve the locking purpose, a ratchet and pawl mechanism is provided on the second disc body 17. In this embodiment, since the second disc body 17 is fixedly connected to the second ring 1202 of the first one-way clutch 12, the ratchet 19 of the ratchet and pawl mechanism rotates synchronously with the second ring 1202 of the first one-way clutch 12 through spline engagement. The pawl 20 of the ratchet and pawl mechanism is provided on the base 3. Two pins 21 are provided on the base 3. One pin 21 is used to install the pawl 20, and the other pin 21 is used to install a spring. The other end of the spring is connected to the pawl 20, so that the pawl 20 abuts against the ratchet teeth of the ratchet 19, locking the counterclockwise rotation of the ratchet 19.

[0029] The working process of the curtain wall exterior surface irregular component extraction device is as follows: When not gripping, the J-shaped support rod 5 is in a horizontal position extending laterally along the direction of the crossbeam 2, which is the uppermost position of the J-shaped support rod 5. When gripping an object, the terminal position first moves down (the connecting plate 1 moves down as a whole). Since there are three points, the vacuum suction cup 4 first contacts the upper surface of the object being gripped. The vacuum suction cup 4 will compress and then generate negative pressure. The three vacuum suction cups 4 firmly hold the object. At this time, the lifting device lifts the object. When there is space under the object, the motor 11 rotates clockwise, driving the main shaft 10 to rotate clockwise. At this time, according to the action of the first one-way clutch 12, the second ring 1202 of the first one-way clutch 12 drives the ratchet and the second disc 17 to rotate clockwise. The first ring 1301 of the second one-way clutch 13 is idle and will not drive the second ring 1302 of the second one-way clutch 13 to rotate. The friction between the second disc 17 and the friction elastic colloid 16 causes the friction elastic colloid 16 to move from the second one-way clutch 13 to the second one-way clutch 14. Figure 6 First state Figure 7 The second state change gradually causes friction with the first disc 14, which in turn causes the first disc 14 to rotate clockwise. This causes the J-shaped support rod 5 to rotate clockwise to its lowest point, facing the vacuum suction cup 4. The J-shaped support rod 5 supports the lower surface of the object. The motor 11 can then rotate clockwise by a small angle to generate greater friction between the first disc 14, the second disc 17, and the frictional elastic colloid 16. At this point, if an external force causes the J-shaped support rod 5 to rotate counterclockwise, the force is transmitted through the first disc 14, the frictional elastic colloid 16, the second disc 17, and the second ring 1202 of the first one-way clutch 12 to the ratchet 19. Since the ratchet 19 is locked by the pawl 20 and cannot rotate counterclockwise, the J-shaped support rod 5 cannot rotate counterclockwise without sufficient torque, thus preventing accidental rotation of the J-shaped support rod 5. When motor 11 rotates counterclockwise, it drives main shaft 10 to rotate counterclockwise. At this time, the first ring 1201 of the first one-way clutch 12 rotates counterclockwise without rotating, and will not drive the second ring 1202 of the first one-way clutch 12 to rotate. The first ring 1301 of the second one-way clutch 13 rotates counterclockwise, driving the second ring 1302 of the second one-way clutch 13 to rotate counterclockwise. Initially, as mentioned above, due to the friction between the first disc 14, the friction elastic colloid 16, and the second disc 17, the ratchet 19 is locked and cannot rotate counterclockwise. However, as the torque of motor 11 increases, the friction between the first disc 14 and the friction elastic colloid 16 causes the friction elastic colloid 16 to... Figure 7 The second state towards Figure 6 The first state change causes the first disc 14 to "disengage" from the second disc 17, and the ratchet no longer locks the J-shaped support rod 5. The J-shaped support rod 5 can rotate counterclockwise to return to the horizontal extension position along the crossbeam 2. After the object is moved and installed in place, the vacuum suction cup 4 releases pressure, releases the object, and completes the work.
