Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to an auxiliary device for hoisting steel structures. Background Technology

[0002] Steel structures are made of steel materials such as shaped steel and steel plates, and are one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity, and strong deformation capacity, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. In steel structure installation, hoisting equipment is required to precisely install components into designated positions. Hoisting equipment helps operators accurately control the position and orientation of components, thereby ensuring the accuracy and quality of installation.

[0003] During the actual lifting operation, the steel structural components are assembled using the hook and lifting gear. After inspection, the actual lifting begins. The winch mechanism is started slowly, the condition is observed, and the boom and speed are controlled. A slow, inspected lift is performed before proceeding with the lifting along the designated path. When in position, the crane's installation position is manipulated, with the aid of a guide rope or a signalman. As it approaches, it is gently lowered and connected, or a temporary securing device is used. After completion, the hook is released to unload the load. The steel structural components and the crane are inspected, the site is cleaned, and the crane is moved.

[0004] Although existing hoisting equipment has many advantages, it still has the following shortcomings in actual use: During use, dust particles gradually penetrate into the rope fibers; when the rope is under stress, these dust particles will cut and abrade the rope fibers, like countless tiny blades continuously acting inside the rope; over time, this will reduce the strength of the rope, not only shortening its service life but also posing safety hazards. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing hoisting equipment, where dust particles can easily cause ropes to tear and wear, thus shortening their service life, and to provide an auxiliary device for steel structure hoisting.

[0006] This utility model is achieved through the following technical solution: a steel structure hoisting auxiliary device, including a base, a hoisting rope, and a drive assembly. Two symmetrically arranged support assemblies are provided on the top side of the base, and the top ends of the two support assemblies are connected to a support frame. A guide wheel A is provided at the end of the support frame near the support assembly via a positioning shaft A, and a guide wheel B is provided at the end of the support frame away from the support assembly via a positioning shaft B. A cleaning cylinder is provided inside the support frame via a connecting assembly, located between the guide wheels A and B. Several rows of cleaning brushes are arranged circumferentially inside the cleaning cylinder. The cleaning cylinder, in conjunction with the guide wheels A and B, can clean the hoisting rope through the cleaning brushes. The drive assembly is located on the top side of the base, and the hoisting rope is mounted on the drive assembly. One end of the hoisting rope passes through the cleaning cylinder via guide wheel A, and then through guide wheel B before being connected to a hoisting hook.

[0007] The two support components on the base provide stable support for the entire device. The support frame at its top is equipped with guide wheels A and B via positioning shafts A and B, respectively, to guide the direction of the lifting rope. After the drive assembly is activated, the lifting rope is retracted and extended. One end of the lifting rope passes sequentially through guide wheel A, the cleaning cylinder, and guide wheel B before connecting to the lifting hook. Multiple rows of cleaning brushes arranged circumferentially inside the cleaning cylinder contact the surface of the lifting rope as the cleaning cylinder moves with it or slides on its own, removing adhering dust and other impurities through relative motion.

[0008] A further improvement of this utility model is that the connecting assembly includes two connecting plates symmetrically arranged on both sides of the guide wheel A, and the two connecting plates are fixed to the inner sidewall of the support frame; two symmetrically arranged strip-shaped inclined plates are provided between the two connecting plates, and the two strip-shaped inclined plates are rotatably connected to the two connecting plates through a connecting shaft; the cleaning cylinder is located between the two strip-shaped inclined plates, and the end of the strip-shaped inclined plate away from the guide wheel A is rotatably connected to the cleaning cylinder through a connecting post A.

[0009] A further improvement of this utility model is that the connecting plate is provided with a strip groove A corresponding to the connecting shaft, and the two ends of the connecting shaft are slidably connected to the strip groove A respectively; elliptical grooves are provided on both sides of the guide wheel A, and a connecting post B is rotatably provided at the end of the strip inclined plate near the guide wheel A, and the end of the connecting post B near the guide wheel A is slidably connected to the elliptical groove.

[0010] A further improvement of this utility model is that a strip groove B is provided on the connecting plate, the strip groove B is parallel to the strip groove A and located above the strip groove A; a strip plate A is provided between the two connecting plates, and both ends of the strip plate A are slidably connected to the strip groove B; the side of the strip plate A facing the cleaning cylinder is connected to the strip plate B, and the end of the strip plate B near the cleaning cylinder is connected to the cleaning cylinder.

[0011] A further improvement of this utility model is that a fixing plate is provided at the end of the support frame away from the support component, the top end of the fixing plate is connected to the support frame, and the bottom end of the fixing plate is connected to the corresponding end of the base; a side plate is provided on the side of the fixing plate facing the lifting hook, and a motor B is provided on the top side of the side plate. The output shaft of the motor B is connected to a telescopic rod, and a positioning ring is connected to the end of the telescopic rod near the lifting rope. The lifting rope passes through the positioning ring.

[0012] A further improvement of this utility model is that the positioning ring is provided with two symmetrically arranged springs inside. One end of the spring is connected to the inner side wall of the positioning ring, and the other end of the spring is connected to a circular plate. The two circular plates are respectively connected to a sliding shaft on their opposite sides, and the two sliding shafts are respectively connected to an arc-shaped plate on their opposite ends. The two arc-shaped plates are symmetrically arranged, and a space for the hoisting rope to pass through can be formed between the two arc-shaped plates.

[0013] A further improvement of this utility model is that the support assembly includes two symmetrically arranged triangular plates, which are fixed to the top side of the base. Support legs are respectively connected to the opposite sides of the two triangular plates. The top of the support legs is connected to the support frame, and the bottom of the support legs is connected to the top side of the base.

[0014] A further improvement of this utility model is that the drive assembly includes a motor A and two symmetrically arranged upright plates. The two upright plates are fixed to the top side of the base. The exterior of the motor A is fixed inside one of the upright plates. The output shaft of the motor A is connected to a rotating shaft for mounting a lifting rope. The end of the rotating shaft near the other upright plate is rotatably connected to that upright plate.

[0015] A further improvement of this utility model is that an I-shaped column is provided on the rotating shaft, and the hoisting rope is assembled on the I-shaped column.

[0016] A further improvement of this utility model is that the lifting rope is connected to the lifting hook via a counterweight disc, the top side of the counterweight disc is connected to the lifting rope, and the bottom side of the counterweight disc is connected to the lifting hook.

[0017] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0018] 1. This device, through the combination of a strip-shaped inclined plate, a cleaning cylinder, and multiple rows of cleaning brushes, allows the lifting rope to slide back and forth during the hoisting rope's winding and unwinding process, continuously cleaning the surface of the lifting rope. This prevents dust particles from adhering for a long time, which would cause the rope fibers to be damaged by friction, thereby reducing wear at the source and extending the service life of the lifting rope.

[0019] 2. This device utilizes an elastic limiting structure composed of a motor, telescopic rod, positioning ring, spring, and arc plate. It can adjust the posture of the positioning ring according to the position of the steel structure, and absorb and buffer the swaying force of the hoisting rope through the elastic potential energy of the spring, limiting its swaying amplitude. This prevents the steel structure from tilting to vertical and causing large swaying during hoisting, which would affect the positioning accuracy and improve the stability and safety of the hoisting process.

[0020] 3. This device forms a stable load-bearing and power transmission system through the support components (triangular plate, support legs) and drive components (motor, rotating shaft, I-shaped column). With the help of the connecting components (connecting plate, strip inclined plate, connecting shaft, etc.), the cleaning cylinder is precisely guided, ensuring that the guide wheels, cleaning cylinder and other components operate stably during hoisting. The coordinated work of all structures not only ensures the continuity of the cleaning function, but also improves the reliability and durability of the overall device. Attached Figure Description

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Please refer to the attached document. Figure 1 and Figure 2 The following is a description of a specific embodiment: The steel structure hoisting auxiliary device of this utility model includes a base 1, a hoisting rope 21, and a drive assembly. Two symmetrically arranged support assemblies are provided on the top side of the base 1, and the top ends of the two support assemblies are connected to a support frame 4. A guide wheel A6 is provided at the end of the support frame 4 near the support assembly via a positioning shaft A5, and a guide wheel B601 is provided at the end of the support frame 4 away from the support assembly via a positioning shaft B501. A cleaning cylinder 12 is provided inside the support frame 4 via a connecting assembly, located between the guide wheel A6 and the guide wheel B601. Several rows of cleaning brushes 13 are arranged circumferentially inside the cleaning cylinder 12. The cleaning cylinder 12, in conjunction with the guide wheels A6 and B601, can clean the hoisting rope 21 through the cleaning brushes 13. The drive assembly is located on the top side of the base 1, and the hoisting rope 21 is mounted on the drive assembly. One end of the hoisting rope 21 passes through the cleaning cylinder 12 via the guide wheel A6, and then through the guide wheel B601 before being connected to a hoisting hook 31.

[0030] The two support components on the base 1 provide stable support for the entire device. The support frame 4 at its top is equipped with guide wheels A6 and B601 via positioning shafts A5 and B501, respectively, to guide the direction of the hoisting rope 21. After the drive component is started, the hoisting rope 21 is retracted and extended. One end of the hoisting rope 21 passes through guide wheel A6, cleaning cylinder 12, and guide wheel B601 in sequence before connecting to the hoisting hook 31. Multiple rows of cleaning brushes 13 arranged circumferentially inside the cleaning cylinder 12 come into contact with the surface of the hoisting rope 21 as the cleaning cylinder 12 moves with the hoisting rope 21 or slides on its own, removing attached dust and other impurities through relative motion.

[0031] This device, through the cooperation of the support components and the support frame 4, ensures the stable installation of the guide wheel A6, guide wheel B601 and cleaning cylinder 12. The cleaning brush 13 inside the cleaning cylinder 12 can effectively clean the dust on the surface of the hoisting rope 21, preventing dust from adhering for a long time and causing the fibers of the hoisting rope 21 to be damaged by friction, thereby extending the service life of the hoisting rope 21.

[0032] For details, please refer to the appendix. Figure 3 The connecting assembly includes two connecting plates 7 symmetrically arranged on both sides of the guide wheel A6, and the two connecting plates 7 are fixed to the inner sidewall of the support frame 4; two symmetrically arranged strip-shaped inclined plates 10 are provided between the two connecting plates 7, and the two strip-shaped inclined plates 10 are rotatably connected to the two connecting plates 7 through a connecting shaft 9; the cleaning cylinder 12 is located between the two strip-shaped inclined plates 10, and the end of the strip-shaped inclined plate 10 away from the guide wheel A6 is rotatably connected to the cleaning cylinder 12 through a connecting column A11.

[0033] In the connecting assembly, two connecting plates 7 are fixed to the inner sidewall of the support frame 4, and two strip-shaped inclined plates 10 are rotatably connected to the connecting plates 7 via connecting shafts 9, forming a movable connecting structure. The cleaning cylinder 12 is located between the two strip-shaped inclined plates 10 and is rotatably connected to the strip-shaped inclined plates 10 via connecting column A11. When the hoisting rope 21 moves, it drives the guide wheel A6 to rotate, which in turn causes the strip-shaped inclined plates 10 to swing or slide around the connecting shafts 9 as a fulcrum through related structures, thereby driving the cleaning cylinder 12 to move between the guide wheel A6 and the guide wheel B601.

[0034] This device uses the rotatable connection between the strip-shaped inclined plate 10, the connecting plate 7, and the cleaning cylinder 12 to allow the cleaning cylinder 12 to flexibly adjust its position according to the movement trajectory of the hoisting rope 21, ensuring that the cleaning brush 13 always adheres to the surface of the hoisting rope 21, thereby improving the cleaning effect. At the same time, this connection structure is stable and reliable, ensuring the continuity of the cleaning process.

[0035] For details, please refer to the appendix. Figure 4The connecting plate 7 has a strip groove A8 corresponding to the connecting shaft 9, and the two ends of the connecting shaft 9 are slidably connected to the strip groove A8 respectively; the guide wheel A6 has an elliptical groove 17 on both sides respectively, and the strip inclined plate 10 is rotatably provided with a connecting column B16 near the guide wheel A6, and the end of the connecting column B16 near the guide wheel A6 is slidably connected to the elliptical groove 17.

[0036] The strip groove A8 on the connecting plate 7 provides a sliding track for the connecting shaft 9. Both ends of the connecting shaft 9 slide within the strip groove A8, allowing the strip inclined plate 10 to move in a specific direction. The elliptical grooves 17 on both sides of the guide wheel A6 slide in conjunction with the connecting column B16 on the strip inclined plate 10. When the guide wheel A6 rotates or the hoisting rope 21 moves, the connecting column B16 slides within the elliptical groove 17, guiding the strip inclined plate 10 to reciprocate, thereby causing the cleaning cylinder 12 to slide left and right.

[0037] This device precisely guides the movement trajectory of the strip-shaped sliding groove 10 through the cooperation of the strip-shaped sliding groove A8 and the elliptical sliding groove 17, so that the cleaning cylinder 12 can slide back and forth stably on the hoisting rope 21, ensuring that the cleaning brush 13 fully covers the surface of the hoisting rope 21, with no dead corners, effectively removing dust and further improving cleaning efficiency.

[0038] For details, please refer to the appendix. Figure 4 A strip groove B801 is provided on the connecting plate 7. The strip groove B801 is parallel to the strip groove A8 and located above the strip groove A8. A strip plate A15 is provided between the two connecting plates 7. The two ends of the strip plate A15 are slidably connected to the strip groove B801. A strip plate B14 is connected to the side of the strip plate A15 facing the cleaning cylinder 12. The end of the strip plate B14 near the cleaning cylinder 12 is connected to the cleaning cylinder 12.

[0039] The strip groove B801 on the connecting plate 7 is parallel to the strip groove A8. The two ends of the strip plate A15 slide within the strip groove B801, and the strip plate B14 connected to one side is connected to the cleaning cylinder 12. When the strip inclined plate 10 moves, it drives the strip plate A15 to slide within the strip groove B801, thereby causing the cleaning cylinder 12 to move along with it via the strip plate B14.

[0040] This device, through the cooperation of the strip plate A15, strip plate B14 and strip groove B801, provides additional support and guidance for the cleaning cylinder 12, enhances the stability of the cleaning cylinder 12 when it moves, prevents it from shaking or deviating during movement, ensures that the cleaning brush 13 and the hoisting rope 21 maintain good contact pressure, improves the cleaning effect, and makes the structure of the entire connecting assembly more robust.

[0041] For details, please refer to the appendix. Figure 1 and 2 A fixing plate 32 is provided at the end of the support frame 4 away from the support component. The top end of the fixing plate 32 is connected to the support frame 4, and the bottom end of the fixing plate 32 is connected to the corresponding end of the base 1. A side plate 22 is provided on the side of the fixing plate 32 facing the lifting hook 31. A motor B23 is provided on the top side of the side plate 22. The output shaft of the motor B23 is connected to a telescopic rod 24. A positioning ring 25 is connected to the end of the telescopic rod 24 near the lifting rope 21. The lifting rope 21 passes through the positioning ring 25.

[0042] The fixed plate 32 connects the support frame 4 and the base 1, providing stable support. The motor B23 on the side plate 22 drives the telescopic rod 24 to rotate and extend, adjusting the position of the positioning ring 25 so that the lifting rope 21 passes through the positioning ring 25. When the lifting rope 21 is lowered or the steel structure is lifted, the motor B23 can adjust the telescopic rod 24 according to the position of the steel structure, so that the positioning ring 25 is close to the steel structure.

[0043] This device can flexibly adjust the position of the positioning ring 25 through the motor B23 and the telescopic rod 24. During the hoisting process, it can effectively guide the direction of the hoisting rope 21, avoiding inaccurate positioning or safety hazards caused by excessive swaying of the hoisting rope 21 when the steel structure is tilted to vertical, thus improving the stability and safety of the hoisting operation.

[0044] For details, please refer to the appendix. Figure 1 and 2 The drive assembly includes a motor A19 and two symmetrically arranged upright plates 18. The two upright plates 18 are fixed to the top side of the base 1. The motor A19 is externally fixed to the inside of one of the upright plates 18. The output shaft of the motor A19 is connected to a rotating shaft 33 for mounting a lifting rope 21. The end of the rotating shaft 33 near the other upright plate 18 is rotatably connected to that upright plate 18.

[0045] In the drive assembly, two upright plates 18 are fixed to the top side of the base 1. A motor A19 is installed inside one of the upright plates 18, and its output shaft is connected to a rotating shaft 33. The other end of the rotating shaft 33 is rotatably connected to the other upright plate 18. After the motor A19 is started, it drives the rotating shaft 33 to rotate, thereby realizing the winding or unwinding of the hoisting rope 21 mounted on the rotating shaft 33.

[0046] This device provides stable mounting support for the motor A19 and the rotating shaft 33 through the upright plate 18. The motor A19 drives the hoisting rope 21 to be wound and released through the rotating shaft 33. The power transmission is stable and reliable, and the speed and length of the hoisting rope 21 can be precisely controlled to meet the needs of different hoisting scenarios. At the same time, it ensures the smoothness of the entire driving process and avoids the impact of unstable power transmission on hoisting operations and cleaning functions.

[0047] In one embodiment, reference is made to the appendix. Figure 5 The positioning ring 25 has two symmetrically arranged springs 26 inside. One end of the spring 26 is connected to the inner side wall of the positioning ring 25, and the other end of the spring 26 is connected to a circular plate 27. The two circular plates 27 are respectively connected to a sliding shaft 28 on their opposite sides, and the two sliding shafts 28 are respectively connected to an arc plate 29 on their opposite ends. The two arc plates 29 are symmetrically arranged, and a space can be formed between the two arc plates 29 for the hoisting rope 21 to pass through.

[0048] The two springs 26 inside the positioning ring 25 are connected to a circular plate 27, and the circular plate 27 is connected to an arc-shaped plate 29 via a sliding shaft 28. The two arc-shaped plates 29 form a space to accommodate the lifting rope 21. When the lifting rope 21 is subjected to force and sways, it squeezes the arc-shaped plate 29, causing the circular plate 27 to compress the springs 26, and the springs 26 store elastic potential energy. When the swaying force decreases, the springs 26 return to their original position, and through the circular plate 27 and the sliding shaft 28, they drive the arc-shaped plate 29 to return to its original position, applying a reverse force to the lifting rope 21 and limiting its swaying.

[0049] This device forms an elastic limiting structure through the cooperation of the spring 26 and the arc plate 29, which can effectively absorb and buffer the swaying energy of the hoisting rope 21, reduce the swaying amplitude of the hoisting rope 21, improve the stability of the steel structure during hoisting, avoid excessive friction between the hoisting rope 21 and other components due to swaying, further protect the hoisting rope 21, and improve the reliability of the device.

[0050] In one embodiment, reference is made to the appendix. Figure 1 and 2 The support assembly includes two symmetrically arranged triangular plates 2, which are fixed to the top side of the base 1. Support legs 3 are connected to the opposite sides of the two triangular plates 2. The top of the support legs 3 is connected to the support frame 4, and the bottom of the support legs 3 is connected to the top side of the base 1.

[0051] The two triangular plates 2 in the support assembly are fixed to the top side of the base 1. The top of the support leg 3 on the opposite side is connected to the support frame 4, and the bottom is connected to the base 1, forming a stable triangular support structure, which provides support for the support frame 4 and the guide wheel A6, guide wheel B601, cleaning cylinder 12 and other components installed on it.

[0052] The combination of the triangular plate 2 and the support leg 3 in this device forms a stable support structure, which enhances the load-bearing capacity and anti-overturning capacity of the entire device, ensures that the support frame 4 remains stable during the hoisting process, and avoids the displacement of the guide wheel A6 and guide wheel B601 due to unstable support, thereby ensuring that the cleaning effect of the cleaning cylinder 12 on the hoisting rope 21 is not affected.

[0053] In one embodiment, reference is made to the appendix. Figure 1 and 2An I-shaped column 20 is provided on the rotating shaft 33, and a hoisting rope 21 is assembled on the I-shaped column 20.

[0054] The I-shaped column 20 on the rotating shaft 33 is used to fix the lifting rope 21. When the rotating shaft 33 rotates, the I-shaped column 20 rotates accordingly, realizing the winding or unwinding of the lifting rope 21. The lifting rope 21 is wound in an orderly manner on the I-shaped column 20 to avoid knotting or confusion.

[0055] The structural design of the I-shaped column 20 in this device allows the lifting rope 21 to be neatly wound around the rotating shaft 33, reducing friction and wear between the lifting rope 21 and the rotating shaft 33 during the winding and unwinding process, extending the service life of the lifting rope 21, and ensuring smooth winding and unwinding of the lifting rope 21, thereby improving the working efficiency and reliability of the drive components.

[0056] In one embodiment, reference is made to the appendix. Figure 1 and 2 The lifting rope 21 is connected to the lifting hook 31 through the counterweight disc 30. The top side of the counterweight disc 30 is connected to the lifting rope 21, and the bottom side of the counterweight disc 30 is connected to the lifting hook 31.

[0057] The lifting rope 21 is connected to the lifting hook 31 via a counterweight disc 30. The top side of the counterweight disc 30 is connected to the lifting rope 21, and the bottom side is connected to the lifting hook 31. During the lifting process, the counterweight disc 30 increases the stability of the end of the lifting hook 31, enabling the lifting hook 31 to smoothly hook and release the steel structure.

[0058] This device balances the force on the lifting hook 31 by setting the counterweight disc 30, reducing the swaying of the lifting hook 31 during the lifting process, making the lifting and positioning of the steel structure more accurate. At the same time, it disperses the stress at the connection between the lifting rope 21 and the lifting hook 31, avoiding the breakage or damage of the lifting rope 21 due to stress concentration, and improving the safety and reliability of the lifting operation.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
