DETAILED DESCRIPTION

[0032] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0033] Example 1: Reference Figure 1-Figure 13 A lifting device for prefabricated components of assembled buildings, comprising: a lifting ring 1, an inverted U-shaped rubber tube 2, a connecting mechanism 3 and a lifting mechanism 4, wherein the lifting ring 1 is installed at the top of the connecting mechanism 3, and the bottom of the connecting mechanism 3 is connected to the lifting mechanism 4, a cavity is opened inside the lifting ring 1, and the cavity is connected to a guide groove on the inner wall of the lifting ring 1, an inverted U-shaped rubber tube 2 is inserted into the cavity, and hydraulic oil is filled in the inverted U-shaped rubber tube 2.

[0034] The guide groove is arranged along the length direction of the inner wall of the lifting ring 1 .

[0035] The principles and beneficial effects of the above scheme are:

[0036] The bottom end of the lifting ring 1 is connected to the top end of the connecting mechanism 3, and the bottom end of the connecting mechanism 3 is connected to the top end of the lifting mechanism 4. The lifting mechanism 4 clamps the component. Before lifting the component, the hook of the equipment is inserted into the lifting ring 1, and the hook is moved upward. The hook applies pressure to the top of the inverted U-shaped rubber tube 2. The hydraulic oil at the top of the inverted U-shaped rubber tube 2 is squeezed into the two sides of the inverted U-shaped rubber tube 2, thereby expanding the volume of the two sides of the inverted U-shaped rubber tube 2. The two sides of the inverted U-shaped rubber tube 2 increase the friction force on the side of the hook, thereby reducing the left and right shaking of the device during the lifting process and avoiding damage or falling off of the lifted component.

[0037] Example 2: Reference Figure 1-Figure 13 The connecting mechanism 3 includes: a connecting rod 5, the lifting ring 1 is installed at the top of the connecting rod 5, and a spherical connector 6 is installed at the bottom of the connecting rod 5. The spherical connector 6 is rotatably connected to the spherical groove of the mounting seat 7.

[0038] The principles and beneficial effects of the above scheme are:

[0039] During lifting, the hook applies an upward pulling force to the lifting ring 1, and the lifting ring 1 drives the connecting rod 5 to move upward through the connecting rod 5. Since a spherical connector 6 is installed at the bottom end of the connecting rod 5, the spherical connector 6 is rotatably connected to the spherical groove of the mounting seat 7, so the upward movement of the connecting rod 5 can drive the mounting seat 7 to move upward; after the mounting seat 7 is lifted, the connecting rod 5 and the lifting ring 1 can swing within a certain degree relative to the mounting seat 7, avoiding the swing of the lifting ring 1 directly exerting on the mounting seat 7, thereby further improving the stability of the mounting seat 7.

[0040] Example 3: Reference Figure 1-Figure 13The mounting seat 7 is arranged on the mounting plate 9 of the lifting mechanism 4 , and the top ends of a plurality of hydraulic shock absorbers 8 are hinged equidistantly on the side wall of the connecting rod 5 , and the bottom end of each hydraulic shock absorber 8 is hinged to the mounting plate 9 .

[0041] The principles and beneficial effects of the above scheme are:

[0042] When the mounting seat 7 moves upward, the mounting plate 9 moves upward synchronously. The top ends of multiple hydraulic shock absorbers 8 are equidistantly hinged on the side walls of the connecting rod 5, and the bottom ends of each hydraulic shock absorber 8 are hinged to the mounting plate 9. The hydraulic shock absorbers 8 can absorb the front and rear and left and right shaking of the device after it is hoisted, and quickly stabilize the device and the hoisted components. After the device hoisted by the hook is moved, the hydraulic shock absorbers 8 can continue to absorb the shaking of the device caused by acceleration during the movement, further improving the stability of the device during hoisting and movement, and preventing the risk of the hoisted components falling. Since the mounting seat 7 is arranged on the mounting plate 9, the spherical connector 6 and the hydraulic shock absorber 8 work together, which can not only buffer the swing of the lifting ring 1 to a certain extent, but also quickly absorb the swing, thereby achieving the purpose of rapid stabilization of the device after hoisting.

[0043] Example 4: Reference Figure 1-Figure 13 The lifting mechanism 4 also includes: a double screw 10, the bottom end of the mounting plate 9 is rotatably connected with the double screw 10, the double screw 10 is placed below the bottom surface of the mounting plate 9, the end of the double screw 10 is connected to the output end of the motor, the motor is installed at the bottom end of the mounting plate 9, and each threaded segment of the double screw 10 is threadedly connected with a lifting plate 11, and the lifting plate 11 is slidably connected to the bottom surface of the mounting plate 9.

[0044] The principles and beneficial effects of the above scheme are:

[0045] Before clamping the component, start the motor, the output shaft of the motor rotates forward to drive the twin screws 10 to rotate forward, and the two lifting plates 11 approach each other. After the component is lifted, start the motor again, the output shaft of the motor rotates reversely to drive the twin screws 10 to rotate reversely, and the two lifting plates 11 move away from each other. The top of the lifting plate 11 is slidably connected to the bottom surface of the mounting plate 9 to assist in moving the lifting plate 11 and improve the stability of the lifting plate 11 during movement.

[0046] Example 5: Reference Figure 1-Figure 13 Each of the hanging plates 11 is provided with a rubber bag 12 , the two rubber bags 12 are arranged opposite to each other, and the rubber bags 12 are filled with hydraulic oil.

[0047] The principles and beneficial effects of the above scheme are:

[0048] When it is necessary to clamp the component, the two lifting plates 11 each drive a rubber bag 12 to move, and the two rubber bags 12 approach each other, and finally clamp the component. Since the rubber bag 12 is filled with hydraulic oil, the hydraulic oil itself has a higher specific heat capacity than rubber. Therefore, when the rubber bag 12 is in an open-air environment, the hydraulic oil can, to a certain extent, assist in absorbing the external high temperature to prevent the temperature of the rubber bag 12 itself from being too high, and can also prevent the temperature of the rubber bag 12 from being too low at low temperatures, thereby improving the ability of the device to adapt to different environments. Since the force is mutual, when the two rubber bags 12 cooperate with each other to clamp the component, the component applies pressure to the rubber bag 12, causing the surface of the rubber bag 12 to be concave, thereby increasing the covering effect on the component and improving the stability of the device for the component during hoisting. At the same time, since the rubber bag 12 is filled with hydraulic oil, the hydraulic oil has a strong ability to resist compression, so the hydraulic oil transmits the pressure to the side of the rubber bag 12, thereby further preventing the contact surface between the rubber bag 12 and the component from being excessively deformed and damaged, thereby improving the service life of the rubber bag 12.

[0049] Example 6: Reference Figure 1-Figure 13 The end face of the hanging plate 11 is rotatably connected with a double screw 13, and the double screw 13 is arranged above the rubber bag 12. Each of the two threaded segments of the double screw 13 is threadedly connected with a screw block 14. The bottom end of the screw block 14 is connected with a cleaning mechanism 15. The cleaning mechanism 15 is frictionally matched with the side wall of the rubber bag 12. A rotating wheel 16 is coaxially installed at each end of the double screw 13. One end of the torsion spring 17 is connected to the end face of the rotating wheel 16, and the other end of the torsion spring 17 is connected to the hanging plate 11.

[0050] Two pairs of connecting plates 18 are installed on the end surface of the hanging plate 11, and each pair of connecting plates 18 is rotatably connected to a shaft tube 19, and a hollow rubber wheel 20 is coaxially installed on each shaft tube 19. The inner wall of the shaft tube 19 passes through the end of a plurality of guide holes 21, and the other end of the guide holes 21 is arranged toward the buffer cavity 22 of the hollow rubber wheel 20. One end of the shaft tube 19 is rotatably connected to the end of a connecting tube 23, and the other end of the connecting tube 23 is connected to the rubber bag 12. The two hollow rubber wheels 20 are each arranged above a rotating wheel 16, and the hollow rubber wheel 20 is arranged below the mounting plate 9.

[0051] The inner wall of the through hole at the other end of the shaft tube 19 is rotatably matched with the side wall of the adjusting tube 24. The end of the adjusting tube 24 away from the hollow rubber wheel 20 is equipped with a sealing disk. The inner wall of the adjusting tube 24 is opened with multiple ends of the second guide holes 25. The other end of the second guide hole 25 is arranged toward the end of the guide hole 21. The axis of the guide hole 21 is staggered with the axis of the second guide hole 25. The inner diameter of the guide hole 21 is larger than the inner diameter of the second guide hole 25.

[0052] The sealing disk of the regulating tube 24 is rotatably connected to the inner wall of the steering tube 40, the open end of the steering tube 40 is connected to the side wall of the connecting plate 18, the side wall of the steering tube 40 is connected to the end of the driving tube 41, the other end of the driving tube 41 is connected to the side wall of the connecting tube 23, the side wall of the regulating tube 24 is equipped with one end of a positioning plate 42, one side of the positioning plate 42 is arranged toward the end of the driving tube 41, the other side of the positioning plate 42 is connected to one end of a spring 43, the other end of the positioning plate 42 is slidably sealed with the inner wall of the steering tube 40, and the spring 43 is connected to the inner wall of the steering tube 40. The other end of the second spring 43 is connected to one side of the second positioning plate 44, the end of the second positioning plate 44 is connected to the inner wall of the steering tube 40, the other end of the second positioning plate 44 is slidingly sealed with the side wall of the adjusting tube 24, the other side of the second positioning plate 44 is arranged above the end of the driving tube 41, and the side wall of the adjusting tube 24 is provided with a mounting ring 45, the mounting ring 45 is rotationally sealed with the inner wall of the steering tube 40, the end face of the mounting ring 45 is slidingly sealed with the positioning plate 42 and the second positioning plate 44, and the mounting ring 45 is arranged between the second spring 43 and the shaft tube 19.

[0053] The principles and beneficial effects of the above scheme are:

[0054] When clamping the component, the spacing between the two hanging plates 11 is reduced. After the rubber bag 12 on the hanging plate 11 contacts the component, the rubber bag 12 itself is squeezed, and the hydraulic oil in the rubber bag 12 enters the adjustment pipe 24 through the connecting pipe 23. At the same time, part of the hydraulic oil enters the steering pipe 40 through the driving pipe 41 and applies pressure to the positioning plate 42. The positioning plate 42 rotates counterclockwise relative to the steering pipe 40 to compress the spring 243. At this time, the adjustment pipe 24 rotates counterclockwise synchronously, and the guide hole 22 5 and the guide hole 21 change from the state of interlaced axes to the state of coincidence of axes, and the hydraulic oil quickly enters the buffer chamber 22 through the guide hole 25, so that after the rubber bag 12 is completely clamped on the components, the hollow rubber wheel 20 can expand rapidly, and the expansion state of the hollow rubber wheel 20 reaches the maximum, and the early expansion of the hollow rubber wheel 20 will not hinder the movement of the hanging plate 11 during the process of the two hanging plates 11 completing the approach. At this time, the two sides of the hollow rubber wheel 20 are in contact with the mounting plate 9 and the rotating wheel 16 respectively;

[0055] After the clamping of the component is completed, the two rubber bags 12 release the component, so that the rubber bag 12 returns to its original shape. During the resetting process, the hydraulic oil in the steering tube 40 enters the connecting tube 23 through the driving tube 41 and then enters the rubber bag 12. Since the hydraulic oil in the steering tube 40 is sucked away by the reset rubber bag 12, the adjustment tube 24 rotates clockwise under the elastic force of the spring 2 43, and the axial staggered state between the guide hole 25 and the guide hole 21 is restored. The hydraulic oil is slowly discharged from the buffer chamber 22 to the connecting tube 23. Therefore, during the resetting process of the two hanging plates 11, the hollow rubber wheel 20 has enough time to contact and cooperate with the mounting plate 9 and the rotating wheel 16 respectively. At this time, as the lifting plate 11 is reset, the upper part of the hollow rubber wheel 20 rolls with the bottom surface of the mounting plate 9 to rotate forward, and the hollow rubber wheel 20 drives the rotating wheel 16 that is frictionally matched with it to rotate in the opposite direction. The rotating wheel 16 drives the double screw 13 to rotate in the opposite direction, and the two screw blocks 14 approach each other, and drive the two cleaning mechanisms 15 to approach each other to perform preliminary cleaning on the side wall of the rubber bag 12. At the same time, as the double screw 13 rotates in the opposite direction, the torsion spring 17 torsional stores energy. After the two cleaning mechanisms 15 finish the preliminary cleaning, the hydraulic oil of the hollow rubber wheel 20 completely enters the rubber bag 12 through the connecting pipe 23, and the volume of the hollow rubber wheel 20 is reduced to end the friction match with the rotating wheel 16. Under the action of the elastic force of the spring 17, the twin screw 13 rotates forward, and the two screw blocks 14 each drive a cleaning mechanism 15 to move away from each other, and clean the side wall of the rubber bag 12 again. The above scheme fully utilizes the hydraulic oil in the rubber bag 12 as the cleaning mechanism 15 to clean the side wall of the rubber bag 12, and at the same time will not affect the clamping of the components; at the same time, the existing structure is fully utilized to accurately control the expansion and contraction of the rotating wheel 16 and the speed of its volume change, which greatly improves the practicality of the device; in addition, the hollow rubber wheel 20 can store part of the hydraulic oil to prevent the rubber bag 12 from being damaged by excessive pressure of the hydraulic oil that expands after being compressed, and further The hydraulic oil in the rubber bag 12 is also affected by excessive temperature or excessive size of the clamped components, which may cause overcharging of the hollow rubber wheel 20. At this time, the end of the buffer tube can be connected to the rubber bag 12. The diameter of the buffer tube is smaller than the diameter of the connecting tube 23. The other end of the buffer tube is connected to the buffer tank, and the buffer tank is set on the lifting plate 11. When the rubber bag 12 is compressed, the hydraulic oil can enter the connecting tube 23 first. When the volume of the buffer cavity 22 reaches the upper limit, the hydraulic oil enters the buffer tube again. The buffer tank can not only accommodate excess hydraulic oil to prevent the buffer cavity 22 from rupturing, but also protect the rubber bag 12. Therefore, a simple mechanism is further utilized to improve the applicability of the device.

[0056] Example 7: Reference Figure 1-Figure 13The cleaning mechanism 15 includes: a steering tube 26, the screw block 14 is rotatably connected to the top of the steering tube 26, the bottom end of the steering tube 26 is provided with a spline slot, the top end of the spline shaft 27 is inserted into the spline slot, the spline shaft 27 is coaxially installed on the top of the cleaning roller 28, the side wall of the cleaning roller 28 is frictionally matched with the side wall of the rubber bag 12, the side wall of the cleaning roller 28 is provided with a plurality of spiral grooves 29, and the inner wall of the spiral groove 29 is provided with the end of a plurality of suction holes 30.

[0057] The principles and beneficial effects of the above scheme are:

[0058] After the components are clamped, debris or dust will remain on the side wall of the rubber bag 12. During the process of the two screw blocks 14 approaching each other, the steering tube 26 and the spline shaft 27 connected to each screw block 14 approach each other. Since the top of the cleaning roller 28 is connected to the spline shaft 27, the cleaning roller 28 rotates in the positive direction during the preliminary cleaning of the side wall of the rubber bag 12; since the cleaning roller 28 and the side wall of the rubber bag 12 are frictionally matched, the rubber bag 12 can guide the movement of the cleaning roller 28; during the process of the two screw blocks 14 moving away from each other, the steering tube 26 and the spline shaft 27 connected to each screw block 14 move away from each other. Since the top of the cleaning roller 28 is connected to the spline shaft 27, the cleaning roller 28 rotates in the positive direction. The cleaning roller 28 is connected to the spline shaft 27. During the process of cleaning the side wall of the rubber bag 12 again by the cleaning roller 28, the cleaning roller 28 rotates in the opposite direction. Since a plurality of spiral grooves 29 are provided on the side wall of the cleaning roller 28, the spiral grooves 29 can clean the protruding debris on the side wall of the rubber bag 12. The side wall of the cleaning roller 28 cleans the dust on the side wall of the rubber bag 12. The side wall of the cleaning roller 28 cooperates with the spiral grooves 29 to guide the larger debris and peel it off from the side wall of the rubber bag 12. The cleanliness of the side wall of the rubber bag 12 is improved after two cleanings. The efficiency of cleaning the side wall of the rubber bag 12 is improved by arranging the spiral grooves 29 on the cleaning roller 28.

[0059] Example 8: Reference Figure 1-Figure 13 The bottom end of the steering tube 26 is connected to the top of a spring 31, and the bottom end of the spring 31 is connected to the top of a cleaning roller 28. A suction chamber is provided in the cleaning roller 28, and the other end of the suction hole 30 is provided on the inner wall of the suction chamber. The bottom end of the spline shaft 27 placed in the suction chamber is rotatably connected to the top of an auger 32, and the bottom side wall of the auger 32 is rotatably connected to the steering hole. The steering hole is penetrated and provided on the bottom wall of the suction chamber, and the top of an ash discharge hole 33 is provided on the side wall of the auger 32. The top of the ash discharge hole 33 is placed in the suction chamber, and the bottom end of the ash discharge hole 33 is provided on the bottom surface of the auger 32.

[0060] A guide plate 34 and a gear 35 are coaxially installed at the bottom of the auger 32 from top to bottom. The guide plate 34 is arranged below the cleaning roller 28. The end face of the hanging plate 11 is connected to the end of the bottom plate 36. Two waist-shaped grooves 37 are penetrated on the bottom plate 36. A guide bar 38 is installed on each inner wall of the waist-shaped groove 37. A storage portion is formed between the end of the guide bar 38 and the inner wall of the waist-shaped groove 37 facing it. The bottom of the auger 32 is placed in the storage portion away from the center of the bottom plate 36. The area of ​​the storage portion is larger than the area of ​​the guide plate 34. The guide bar 38 is slidably matched with the guide plate 34. The length of the guide bar 38 is smaller than the length of the waist-shaped groove 37. The distance between the end of the guide bar 38 and the inner wall of the waist-shaped groove 37 facing it is larger than the diameter of the guide plate 34. The end of a rack 39 is installed on the inner wall of the waist-shaped groove 37. The other end of the rack 39 is arranged toward the end of the bottom plate 36. The rack 39 is arranged below the gear 35, and the gear 35 is arranged below the guide bar 38.

[0061] The principles and beneficial effects of the above scheme are:

[0062] When the two screw blocks 14 are close to each other, the side wall of the cleaning roller 28 and the side wall of the rubber bag 12 are frictionally matched. At this time, the cleaning roller 28 rotates in the positive direction. At the same time, after the guide plate 34 leaves the storage portion away from the center of the bottom plate 36, the bottom surface of the guide plate 34 and the top surface of the guide strip 38 slide and match. As the cleaning roller 28 moves, the guide plate 34 ends the sliding match with the guide strip 38 and enters the storage portion at the center of the bottom plate 36. When there is less dust or debris on the side wall of the rubber bag 12, it can be directly cleaned up by the friction of the cleaning roller 28. Therefore, the weight of the cleaning roller 28 is light, and the cleaning roller 28 will not move downward. When the two screw blocks 14 move away from each other, the guide plate 34 leaves the storage portion at the center of the bottom plate 36, and the bottom surface of the guide plate 34 slides with the top surface of the guide strip 38. After the sliding cooperation with the guide strip 38 ends, it enters the storage portion away from the center of the bottom plate 36 again. When there is a lot of dust or debris on the side wall of the rubber bag 12, some dust or debris will exist on the cleaning roller 28, so the overall loading of the cleaning roller 28 becomes heavier, and the cleaning roller 28 drives the spline shaft 27 to move downward. The top of the spline shaft 27 is plugged into the spline slot, and the spline slot is the top of the spline shaft 27. The spring 31 is extended, and the auger 32, the guide plate 34 and the gear 35 move downward. The receiving portion of the guide plate 34 at the center of the bottom plate 36 drops. As the two screw blocks 14 move away from each other, the gear 35 begins to mesh with the rack 39. The top surface of the guide plate 34 and the bottom surface of the guide bar 38 slide together to prevent the auger 32 from moving upward. Since the cleaning roller 28 rotates in the opposite direction at this time, the gear 35 is meshed with the rack 39, so the gear 35 can drive the auger 32 to rotate forward. The rotation of the auger 32 reduces the air pressure in the suction chamber. , dust or debris is sucked into the suction chamber through the suction hole 30, and then discharged to the bottom of the bottom plate 36 through the dust discharge hole 33. When the gear 35 ends the meshing connection with the rack 39, the weight of the cleaning roller 28 is reduced. Under the pulling force of the spring 31 to reset, the cleaning roller 28 rises to a height away from the storage part at the center of the bottom plate 36 to prepare for the next cleaning. The above scheme improves the ability of the device to work independently and further improves the cleanliness of the device by selecting whether to start the auger 32 to suck dust or debris according to the actual weight of the cleaning roller 28.
