Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a material lifting mechanism for building a steel structure shed. Background Art

[0002] In the construction process, the lifting of materials is an indispensable link, and the performance of lifting equipment is directly related to the efficiency and safety of construction. In order to meet the requirements of efficient, safe and stable operation in modern construction scenes, the lifting mechanism not only needs to have large load and high-frequency operation capabilities, but also needs to achieve reliable self-locking protection and equipment durability during the lifting process to avoid safety hazards caused by equipment failure or operating errors.

[0003] Existing building material lifting devices usually adopt a structure in which a motor drives the winding roller, and the lifting and lowering of the material is achieved by winding the lifting rope. The motor is directly connected to the winding roller, and the rotation of the motor drives the operation of the lifting rope. During the operation, the lifting rope is adjusted in direction by the guide wheel, and the lifting and lowering operation of the material is completed by the winding roller. At the same time, in order to realize the basic work of the equipment, the traditional device is mostly equipped with a simple transmission mechanism and a basic power output unit to complete the lifting operation.

[0004] Traditional material lifting devices lack an effective self-locking structure in actual applications. When the motor stops running or fails, the reaction force of the material weight will cause the winding roller to rotate, the lifting rope to loosen, and even cause the material to fall. Or the reaction force will act directly on the drive structure through the winding roller, causing the drive structure to bear a large load and be damaged, posing a major safety hazard.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Reference Figure 1-Figure 3 The utility model provides an embodiment: a material lifting mechanism for building a steel structure shed, including a base 1, a lifting component is installed on the top of the base 1, and the top of the lifting component is fixedly connected to the lifting bin 6. A winding roller 7 for winding up the lifting rope 8 is installed inside the lifting bin 6, and the motor 11 is firmly installed on the top through the mounting plate 9 fixedly connected to the outside. A self-locking component is integrated in the middle of the mounting plate 9, and a lubrication component is installed in the middle of the lifting bin 6 to reduce the wear of the lifting rope 8 during operation. An output component is installed at the bottom of the mounting plate 9 to ensure the supply and reflux of lubricating oil during the operation of the mechanism, and to ensure the smoothness and reliability of the lifting operation. During operation, after the motor 11 is started, the self-locking component drives the winding roller 7 to wind up the lifting rope 8 to steadily lift the building materials. At the same time, the lubrication component will provide uniform lubrication for the lifting rope 8, reduce friction and wear, and thus increase the service life of the equipment;

[0041] Reference Figure 2 , Figure 5 , Figure 6 and Figure 7The self-locking assembly includes a housing 12, a sun gear 13 is installed at the center of the inner wall, and an inner gear ring 22 is fixed in the middle. A planet carrier 14 is installed on the inner side of the inner gear ring 22, one side of the planet carrier 14 is connected to a plurality of planetary gears 15, and the other side is fixed with a plurality of drive rods 16. The planetary gears 15 are meshed with the sun gear 13 and the inner gear ring 22 at the same time to ensure efficient power transmission. A plurality of grooves are designed on the outer wall of the planet carrier 14 to match the drive shaft 18. At the same time, a connecting assembly is installed at the end of the housing 12 away from the motor 11. When the motor 11 is started, the sun gear 13 starts to rotate, driving the planetary gears 15 to run inside the inner gear ring 22, and further driving the planet carrier 14 to rotate. The movement of the planet carrier 14 not only drives the drive rod 16 to run, but also amplifies the output torque of the motor, and finally transmits power to the winding roller 7 through the self-locking assembly, so as to achieve efficient winding of the sling rope 8 and material lifting.

[0042] Reference Figure 5-Figure 7 The connection assembly is an important component of the self-locking assembly, including a self-locking wheel 17 and a rubber ring 21. The rubber ring 21 is close to the inner wall of the housing 12 and wrapped around the outer side of the self-locking wheel 17. The self-locking wheel 17 is connected to the planetary frame 14 through its middle. A plurality of springs 20 are fixed to the outer wall of the self-locking wheel 17, and the other end of each spring 20 is connected to the clamping column 19, thereby forming a stable locking structure. When the material is lifted, the self-locking assembly can drive the self-locking wheel 17 to rotate through the movement of the planetary wheel and the planetary frame, thereby driving the winding roller 7 to run. When the motor 11 stops running, the tension of the suspension rope 8 will cause the self-locking wheel 17 to rotate. At this time, the clamping column 19 quickly moves to the locking position under the friction force of the rubber ring 21 and the elastic force of the spring 20, and is in close contact with the self-locking wheel 17. In this way, after the material is lifted to the target height, even if the motor stops, the self-locking assembly can still keep the suspension rope 8 in a stable state, thereby preventing the building materials from falling back unexpectedly and causing safety hazards.

[0043] Reference Figure 3 , Figure 6 and Figure 7 The middle part of the sun gear 13 passes through the shell 12 and is connected to the output end of the motor 11, and the middle part of the self-locking wheel 17 passes through the lifting bin 6 and is connected between the winding roller 7, so that when the motor 11 is running, it can drive the winding roller 7 to run by driving the self-locking component to achieve the lifting of the material, and at the same time protect the motor 11 with the help of the self-locking structure.

[0044] Reference Figure 6 and Figure 7The grooves on the outer side of the drive shaft 18 and the outer wall of the planet carrier 14 correspond one to one, and the drive shaft 18 is located inside the groove. The size of the groove is larger than the diameter of the drive shaft 18, so that the groove will not contact the drive shaft 18 for the first time during the activity. At the same time, the structure of the groove and the drive shaft 18 ensures that the output torque of the motor 11 is not directly connected to the winding roller 7, thereby avoiding the force exerted on the winding roller 7 from being directly transmitted to the motor 11.

[0045] Reference Figure 5-Figure 7 The spring 20 and the clamping column 19 are both located on the inner side of the rubber ring 21, and the driving rod 16 and the clamping column 19 correspond one to one. The driving rod 16 is located on the side of the clamping column 19 away from the spring 20, so that when self-locking is performed, the clamping column 19 can be in close contact with the rubber ring 21 and the self-locking wheel 17 to achieve locking of the self-locking wheel 17. At the same time, when the driving rod 16 moves in the reverse direction, the driving rod 16 can separate the clamping column 19 and the rubber ring 21, thereby allowing the self-locking wheel 17 to be unlocked, so that the mechanism can release the sling 8.

[0046] Reference Figure 2-Figure 4 The core of the lubrication assembly is the lubrication cylinder 23, the outer side of which is firmly mounted on the center of the inner wall of the lifting bin 6, and the interior is fitted with the lifting rope 8 through multiple smear brushes 24. The bottom of the lubrication cylinder 23 is connected to a return pipe 25, and a filter 26 is installed on the top of the return pipe 25. During the operation of the equipment, the lubrication cylinder 23 evenly applies lubricating oil to the surface of the lifting rope 8 to reduce the friction between the lifting rope 8 and the guide wheel 36. This not only improves the operating efficiency of the equipment, but also extends the service life of the lifting rope 8, ensuring a smoother lifting process.

[0047] Reference Figure 2 and Figure 4 The output assembly is responsible for the supply and circulation of lubricating oil, and mainly includes an oil tank 27 and a cylinder 28. The oil tank 27 is fixed to the bottom of the mounting plate 9 and is used to store lubricating oil; the cylinder 28 is installed in the middle of the mounting plate 9, and completes the pumping operation of the lubricating oil through the sliding structure of the compression spring 29 and the piston 30. The lubricating oil is transported from the cylinder 28 to the lubricating cylinder 23 through the oil outlet pipe 34. A stop valve 35 is also installed in the middle of the oil outlet pipe 34 to adjust the supply of lubricating oil according to actual needs. At the same time, the cylinder 28 is connected to the oil tank 27 through the oil inlet pipe 32, and an electromagnetic one-way valve 33 is installed on the oil inlet pipe 32 to control the reflux of the lubricating oil.

[0048] Reference Figure 4 and Figure 6The linkage assembly is composed of a cam 10 and a T-bar 31. The cam 10 is fixedly mounted on the outside of the output shaft of the motor 11, and the other end of the T-bar 31 is connected to the piston 30. When the motor 11 is started, the cam 10 rotates to push the T-bar 31 to move, and further drives the piston 30 to slide inside the cylinder 28, thereby compressing the lubricating oil and delivering it to the lubricating cylinder 23. When the cam 10 is separated from the T-bar 31, the compression spring 29 pushes the piston 30 to return to its original position, and a negative pressure is formed inside the cylinder 28, thereby drawing the lubricating oil from the oil tank 27 through the oil inlet pipe 32, completing the reflux cycle of the lubricating oil.

[0049] Reference Figure 2 and Figure 3 The outer side of the oil outlet pipe 34 passes through the lifting bin 6, so that the lubricating oil can directly enter the lubricating cylinder 23 through the lifting bin 6. The bottom end of the return pipe 25 is connected to the inside of the oil tank 27, so that the excess lubricating oil in the lubricating cylinder 23 will enter the inside of the return pipe 25, and at the same time, the impurities are filtered by the filter 26, and finally return to the oil tank 27. A guide wheel 36 is installed on the side of the lifting bin 6 away from the winding roller 7, and the outer side of the lifting rope 8 surrounds the outer circumference of the guide wheel 36. The design of the guide wheel 36 optimizes the running path of the lifting rope 8, avoids unnecessary friction between the lifting rope 8 and other components, and thus improves the stability of the lifting process. At the same time, the guide wheel 36 can disperse the tension of the lifting rope 8, further improving the safety and durability of the equipment.

[0050] Reference Figure 1 The lifting assembly includes a mounting platform 2, the bottom of which is fixedly connected to the top of the base 1, the top of the mounting platform 2 is fixedly connected to a support beam 3, the top of the support beam 3 is hinged with a hanging beam 4, a hydraulic rod 5 is installed between the middle of the hanging beam 4 and the outer wall of the support beam 3, and one end of the lifting bin 6 is fixedly connected to the end of the hanging beam 4 away from the support beam 3. By driving the hydraulic rod 5, the angle between the hanging beam 4 and the support beam 3 can be adjusted, and then the overall lifting height of the mechanism can be adjusted to adapt to more complex construction and lifting uses.

[0051] Working principle: When lifting building materials, the materials are bundled and hung on the hook at the bottom of the lifting rope 8, and then the motor 11 is started to drive the self-locking component to operate, thereby driving the winding roller 7 to rotate and reel the lifting rope 8 to achieve the lifting of the building materials. During the process, if the height of the lifting mechanism is too high or too low, the hydraulic rod 5 is started to lift the hanging beam 4 upward or downward, and then the overall lifting height of the mechanism is adjusted;

[0052] When the motor 11 drives the self-locking assembly to lift the building materials to a high place, the motor 11 will drive the sun gear 13 to rotate and then drive the planetary gear 15 to perform a circular motion inside the inner gear ring 22, and then drive the planetary carrier 14 to rotate through the movement of the planetary gear 15, so as to achieve the effect of increasing the output torque of the motor 11. Then, during the rotation process, the planetary carrier 14 will first drive the driving rod 16 on its side to perform a circular motion. At this time, the driving rod 16 rotates counterclockwise. See the attached figure. Figure 5 The planet carrier 14 rotates in the direction shown in the figure, and moves in the direction where the space gap formed by the outer side of the self-locking wheel 17 and the rubber ring 21 is narrow, and does not contact the clamping column 19. Then the planet carrier 14 continues to rotate until the groove structure on the outer side contacts the drive shaft 18, and drives the drive shaft 18 to perform a circular motion, thereby driving the self-locking wheel 17 to rotate. At this time, the self-locking wheel 17 rotates counterclockwise to attach Figure 5 The direction is a reference, and the self-locking wheel 17 will apply a thrust to the clamping column 19 during the rotation process, so that the direction of the force on the clamping column 19 is also counterclockwise, and at this time, the clamping column 19 and the rubber ring 21 contact and generate friction, and the friction force is in the opposite direction of the applied force, that is, at this time, the friction force of the rubber ring 21 on the clamping column 19 is in the clockwise direction, so that the clamping column 19 will continuously move toward the wider part of the gap space outside the self-locking wheel 17, and overcome the elastic force of the spring 20 to compress the spring 20, avoiding close contact between the clamping column 19, the rubber ring 21 and the self-locking wheel 17. At this time, the self-locking wheel 17 rotates to drive the winding roller 7 to rotate and lift the material.

[0053] When the material is lifted to a specified height and stops, the motor 11 stops outputting torque, and the lifting rope 8 generates a pulling force on the winding roller 7 due to the construction material hung at the bottom, causing the winding roller 7 to rotate, and then the winding roller 7 drives the self-locking wheel 17 to rotate. As the self-locking wheel 17 rotates, since the size of the outer notch of the planetary carrier 14 is larger than the diameter of the driving shaft 18, the self-locking wheel 17 will rotate first. During the rotation, the driving rod 16 will move to the narrower direction of the outer notch of the self-locking wheel 17. At the same time, the thrust applied by the self-locking wheel 17 to the clamping column 19 is opposite to the direction during the previous lifting. Similarly, the friction force generated between the clamping column 19 and the rubber ring 21 is also clockwise opposite to the previous direction. In the counterclockwise direction, the clamping column 19 will quickly enter the narrower direction of the notch on the outside of the self-locking wheel 17 under the dual action of the friction force of the rubber ring 21 and the elastic force of the spring 20, and will be in close contact with the self-locking wheel 17 and the rubber ring 21, and the self-locking wheel 17 will be locked by the friction force to prevent the self-locking wheel 17 from rotating, thereby ensuring that the lifted material will not fall suddenly due to the failure of the mechanism. At the same time, the driving shaft 18 and the groove on the outside of the planetary carrier 14 are not in contact, so the gravity of the building material borne by the self-locking wheel 17 at this time will be borne by the friction force generated between the clamping column 19 and the rubber ring 21, and will not be directly transmitted to the motor 11, thereby protecting the motor 11 and extending its service life;

[0054] When the building materials are taken, the mechanism is downwardly lifting the materials, and the motor 11 is reversed, and then drives the planetary frame 14 to rotate in the opposite direction, so that the planetary frame 14 drives the driving rod 16 on its side to rotate clockwise. Figure 5 In the direction shown, then due to the rotational self-locking, when the planetary carrier 14 rotates, the drive shaft 18 is located on the side opposite to its rotation direction, so that the planetary carrier 14 will first drive the drive rod 16 to move, and as the drive rod 16 rotates, it will contact the outer side of the clamping column 19, and then push the clamping column 19 to move in the direction of the spring 20, so that the clamping column 19 is out of the close contact state with the rubber ring 21 and the self-locking wheel 17, and the spring 20 is compressed at the same time. At this time, the outer groove of the planetary carrier 14 contacts the drive shaft 18, and the self-locking wheel 17 is out of the locked state, and then the self-locking wheel 17 rotates to drive the winding roller 7 to rotate, and the lifting rope 8 wound on the outside is released, so that the lifting rope 8 falls to mount the material.

[0055] When the mechanism is used for a long time, in order to prevent the rope 8 on it from being seriously worn, as the mechanism lifts the building materials, the electromagnetic one-way valve 33 is opened. As the motor 11 starts to lift the materials, the motor 11 will also drive the cam 10 to rotate. The rotating cam 10 will push the T-bar 31 abutting against it to move, so that the T-bar 31 will push the piston 30 to extend into the cylinder 28, and at the same time squeeze the lubricating oil and compression spring 29 stored in the cylinder 28, so that the lubricating oil will pass through the stop valve 35 into the oil outlet pipe 34, and then the lubricating oil will enter the lubricating cylinder 23 along the oil outlet pipe 34, and the lubricating oil will be evenly applied to the outside of the rope 8 through the smearing brush 24 inside the lubricating cylinder 23. As the rope 8 is continuously wound and released, the smearing brush 24 will evenly apply the lubricating oil to the outside of the rope 8, reducing the friction generated by the rope 8 during the winding process, and reducing the friction between the rope 8 and the guide wheel 36. The mechanism is smoother when running and the service life of the rope 8 is increased. As the cam 10 continues to rotate, it will slowly break away from the contact with the T-bar 31. At this time, the compressed compression spring 29 inside the cylinder 28 will reset and push the piston 30 to reset and move back. At this time, a negative pressure state is generated inside the cylinder 28, and then the lubricating oil stored in the oil tank 27 is extracted through the oil inlet pipe 32. The lubricating oil passes through the electromagnetic one-way valve 33 and enters the cylinder 28, waiting for the cam 10 to rotate and continue to drive the T-bar 31 and the piston 30 to move, thereby injecting the lubricating oil into the lubrication cylinder 23. At the same time, when the lubricating oil applied is sufficient, the worker can close the electromagnetic one-way valve 33. At this time, the piston 30 can be normally driven by the T-rod 31 to inject the remaining lubricating oil inside the cylinder 28 into the lubricating cylinder 23. However, when the compression spring 29 is reset, since the space where the compression spring 29 is located is in a completely closed state at this time, the compression spring 29 cannot push the piston 30 to reset and extract the lubricating oil, so that the T-rod 31 remains in the state of extending into the cylinder 28, and at this time, the cam 10 will not push the T-rod 31 when it rotates, ensuring the normal operation of the mechanism to lift the materials.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
