Description

Technical Field

[0001] This utility model belongs to the field of hoisting equipment technology, specifically relating to a suspension and hovering device for medium and large objects. Background Technology

[0002] Currently, to make efficient use of space in some interior spaces, it is often necessary to suspend and lock large objects such as beds, large dining tables, conference tables, large workbenches, or retractable decorative ceiling structures from the ceiling, freeing up floor space and expanding their functionality. At present, there are no applications of large-scale heavy-duty suspension devices; only lifting clotheslines with smaller loads are used. However, due to their overly simple anti-fall spring devices and reel structures, the clothesline fixing position is inaccurate and unstable, and the steel cable is prone to tangling during deployment and retraction, resulting in a high failure rate, insufficient safety, and unstable operation. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a suspension and halting device for medium and large objects with high load-bearing capacity, wide applicability, and high stability.

One end of the steel cable is connected to the lifting device via a parallel terminal, and the other end passes through the steering pulley roller and the hanging pulley roller and is connected to the lifting lug. The lifting lug is installed on the loading platform. When an object is placed on the loading platform, the lifting device drives the loading platform to move, thereby causing the suspended object to move.

[0005] Preferably, the lifting device includes a back plate, an outer cover, a worm gear bearing seat bracket, a main shaft, a front plate, and a front cover. The end faces of the back plate and the front plate are connected through the worm gear bearing seat bracket. The outer cover is fitted onto the worm gear bearing seat bracket, and the front cover is connected to the other end face of the front plate.

When the heavy object lands, it rests on its own.

[0014] 2. This utility model has a simple structure, does not require high-precision processing technology, has low manufacturing cost, and is easy to install and construct, which greatly satisfies the realization of special needs.

[0015] 3. The lifting device designed in this utility model has enhanced load-bearing capacity and safety measures, resulting in improved overall performance and cost-effectiveness. On one hand, the structure has undergone numerous structural reinforcements and the addition of a worm gear drive makes lifting heavy objects very effortless. Due to the self-locking characteristic of the worm gear, the weight of the object is borne by the worm gear during lifting or lowering, making operation easy. Simultaneously, a bidirectional ratchet locking structure is incorporated into the system, allowing heavy objects to stop and be locked at any position, ensuring safety.

[0016] 4. The steel cable of this utility model can be detachably and quickly connected to the suspended object. In addition to vertical lifting, the lifting pulley block is also equipped with horizontal guide pulleys, which limit and guide the horizontal layout of the steel cable.

[0017] 5. This utility model adopts a double set of steering pulleys that have flexible rotation capability in the horizontal plane to adapt to the direction of the horizontal steel cable when it enters, thus avoiding possible jamming or dislodging from the chute during operation.

[0018] 6. The lifting device of this utility model is an actuator for lifting and lowering heavy objects. It is required to have a force-saving transmission mechanism, anti-winding measures for the take-up wheel group, a self-locking device during the lifting and lowering process, and a forward and reverse ratchet locking device.

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0038] like Figures 1 to 18As shown, the present invention provides a suspension and hovering device for medium and large objects, including a suspension pulley assembly 1, a steering pulley assembly 2, a steel cable 3, a lifting device 4, a lifting lug 5, a loading platform 6, and a parallel terminal 7. The suspension pulley assembly 1 includes a suspension pulley base 11, a first suspension pulley connector 12, a second suspension pulley connector 13, and a suspension pulley roller 14. The bottom of the suspension pulley base 11 is bolted to the first suspension pulley connector 12, and the first suspension pulley connector 12 is bolted to the second suspension pulley connector 13. The suspension pulley roller 14 is located inside the second suspension pulley connector 13 and is rotatably connected. The steering pulley assembly 2 includes a steering pulley base 21, a first steering pulley connector 22, a second steering pulley connector 23, and a steering pulley roller 24. The steering pulley base 21 and the first steering pulley connector 22 are bolted together, and the first steering pulley connector 22 and the second steering pulley connector 23 are bolted together. The steering pulley roller 24 is located inside the second steering pulley connector 23 and is rotatably connected. One end of the steel cable 3 is connected to the lifting device 4 via a parallel terminal 7, and the other end passes through the steering pulley roller 24 and the suspension pulley roller 14 and is connected to the lifting lug 5. The lifting lug 5 is installed on the loading platform 6. When an object is placed on the loading platform 6, the lifting device 4 drives the loading platform 6 to move, thereby causing the suspended object to move.

[0039] The first connecting member 12 of the hanging pulley is provided with a horizontal roller 15 of the hanging pulley, and the horizontal roller 15 of the hanging pulley is rotatably connected to the first connecting member 12 of the hanging pulley.

[0040] In this embodiment, the axis of the transverse roller 15 of the suspension pulley is perpendicular to the axis of the suspension pulley roller 14. The roller surfaces of both the suspension pulley roller 14 and the transverse roller 15 are concave in a circular groove structure, and the steel cable 3 is located inside the groove structure.

[0041] The second connecting member 13 of the hanging pulley is a slotted rectangular structure. The cross-section of the second connecting member 13 of the hanging pulley is U-shaped. The middle of the hanging pulley roller 14 is provided with a bolt and is rotatably connected. The two ends of the bolt are respectively provided in the second connecting member 13 of the hanging pulley.

[0042] The bottom of the second connecting member 13 of the hanging pulley is provided with a hanging pulley guide block 16. The hanging pulley guide block 16 is a cuboid structure with a groove in the middle. The bottom of the hanging pulley guide block 16 is provided with a hanging pulley guide block through hole 161, through which the steel cable 3 passes.

[0043] The top of the second connecting member 13 of the hanging pulley is provided with a hanging pulley guide plate 17, and the hanging pulley guide plate 17 is provided with a hanging pulley guide plate through hole 171, through which the steel cable 3 passes.

[0044] The number of steering pulley rollers 24 is two, and they are arranged side by side. In this embodiment, the first steering pulley connector 22, the second steering pulley connector 23, and the steering pulley rollers 24 constitute a steering pulley group, and the two steering pulley groups are located side by side on the steering pulley base 21.

[0045] In this embodiment, the structure of the second connecting member 23 of the steering pulley is the same as that of the second connecting member 13 of the hanging pulley. A base plate 25 and a side plate 26 of the steering pulley are fixedly mounted on the second connecting member 23. The base plate 25 has a through hole 251, and the side plate 26 has a through hole 261. Steel cables 3 are respectively threaded through the through holes 251 and 261 of the steering pulley.

[0046] The lifting device 4 includes a back plate 41, an outer cover 42, a worm gear bearing seat bracket 43, a main shaft 44, a front plate 45, and a front cover 46. The end faces of the back plate 41 and the front plate 45 are connected through the worm gear bearing seat bracket 43. The outer cover 42 is fitted onto the worm gear bearing seat bracket 43, and the front cover 46 is connected to the other end face of the front plate 45. One end of the main shaft 44 is rotatably connected to the back plate 41, and the other end of the main shaft 44 passes through the front plate 45 and is rotatably connected. A take-up reel 441, a worm gear 42, and a ratchet 43 are fitted on the main shaft 44. A worm 431 is installed on the worm gear bearing seat bracket 43, and the worm 431 meshes with the worm gear 42. The front plate 45 is provided with a camshaft 450, a switching pulley 451, a snap ring key 452 and a torque spring 453. One end of the camshaft 450 is rotatably connected to the front plate 45, and the other end of the camshaft 450 is connected to the switching pulley 451. The snap ring key 452 is rotatably connected to the front plate 45 and abuts against the torque spring 453. The end of the snap ring key 452 abuts against the ratchet 443. When the switching pulley 451 rotates, it drives the camshaft 450 to rotate, thereby squeezing the snap ring key 452, thus realizing the abutment and separation of the snap ring key 452 and the ratchet 443.

[0047] The worm gear bearing housing bracket 43 includes a bracket column 432 and a bracket plate 433. There are two bracket columns 432 arranged in parallel. One end of each bracket column 432 is fixed to the back plate 41 with screws, and the other end is fixed to the front plate 45 with screws. The bracket plate 433 has a C-shaped cross-section. Both ends of the bracket plate 433 are connected to the back plate 41 and the front plate 45 with screws, respectively. The bracket plate 433 has a through hole through which the end of the worm gear 431 passes.

[0048] In this embodiment, the outer cover 42 is composed of plate-like structures connected together, forming a hollow cuboid frame structure. The outer cover 42 covers the worm gear bearing seat support 43, providing protection for the worm gear bearing seat support 43 and the internal equipment. The plate-like structure is a thin cuboid plate structure.

[0049] The front plate 45 is provided with a bracket end panel post 454 and a bracket end panel screw 455. A torque spring 453 is sleeved on the bracket end panel post 454, with one end of the torque spring 453 connected to the bracket end panel screw 455 and the other end of the torque spring 453 abutting against a snap ring key 452. The snap ring key 452 has a bent structure and includes a snap ring key post 4521 and a snap ring key moving block 4522 fixedly connected in sequence. The snap ring key post 4521 is a cylindrical structure and is rotatably connected to the front plate 45. The snap ring key moving block 4522 has a plate-like structure, with a toothed end. The end of the torque spring 453 abuts against the toothed structure on the snap ring key moving block 4522. During rotation, the end of the snap ring key moving block 4522 abuts against or separates from the ratchet gear 443, thereby realizing the corresponding operation process.

[0050] In this embodiment, a snap ring key fixing post 4523 is fixedly provided on the front plate 45. The snap ring key post 4521 is a hollow structure with an open bottom, and the snap ring key post 4521 is sleeved on the snap ring key fixing post 4523. The end of the snap ring key post 4521 has a snap ring key through hole, which communicates with the cavity inside the snap ring key post 4521. A screw passes through the snap ring key through hole and extends into the snap ring key fixing post 4523, forming a connection and constituting a rotatable screw connection. The screw and the snap ring key post 4521 have a clearance fit. A rotatable screw connection means that the snap ring key post 4521 can rotate around the snap ring key fixing post 4523.

[0051] The snap ring key 452, torque spring 453, bracket end panel post 4521, and bracket end panel screw 455 constitute an adjustment group. Two adjustment groups are symmetrically distributed on both sides of the camshaft 450. During rotation, the camshaft 450 presses different snap ring keys 452, causing the corresponding snap ring key 452 to contact or disengage from the ratchet gear 443. When the snap ring key 452 abuts against the ratchet gear 443, the ratchet gear 443 cannot rotate, thus locking the ratchet gear 443. The use of two adjustment groups in conjunction further increases the stability of the locking mechanism.

[0052] A back plate bearing 410 is installed on the back plate 41, and a front plate bearing 456 is installed on the front plate 45. The two ends of the main shaft 44 are respectively inserted through the back plate bearing 410 and the front plate bearing 456.

[0053] The front cover 46 has a U-shaped cross-section. The end of the camshaft 450 passes through the front cover 46 and is fixedly connected to the center of the switching pulley 451. The front cover 46 is mounted on the front plate 45 and connected by screws, and it protects the internal structure. The switching pulley 451 is located outside the front cover 46.

[0054] The take-up reel 441 is a rotating structure with an annular groove on its end face. The cross-section of the take-up reel 441 is a symmetrical and connected "U" shape. The take-up reel 441 has a first hole 4411 and a second hole 4412, which are connected. The axes of the first hole 4411 and the second hole 4412 are perpendicular to each other. A lifting cable 4413 is housed in the first hole 4411, and a cable locking screw 4414 is housed in the second hole 4412. The second hole 4412 is a threaded hole that threads with the cable locking screw 4414, and the end of the cable locking screw 4414 abuts against the lifting cable 4413. A handle 434 is fitted onto the end of the worm gear 431. The handle 434 has a bent structure and is fixedly connected to the worm gear 431. In use, by rotating the handle 434, the main shaft 44 is driven to rotate through the worm gear connection, thereby realizing the winding operation of the take-up reel 441 on the lifting steel cable 4413.

[0055] In use, this utility model anchors the lifting device to the existing side wall using existing expansion screws. Two 3mm diameter steel cables are released through the handle 434 to lift the steel cable 4413. After adjusting the length and position of the lifting cable 4413, it is locked to complete the installation.

[0056] In this embodiment, the front cover 46 is marked with three positions: "lower," "lock," and "lift." The switching wheel 451 has a cuboid marking. During rotation, the cuboid marking corresponds to the three positions: "lower," "lock," and "lift," thus achieving the corresponding functions. The cuboid marking is a groove structure.

[0057] The switch wheel 451 has three positions, and the rectangular markings correspond to the status positions below, indicating the function status. When aligned with the "lower" position, the handle 434 can be rotated counterclockwise to lower the suspended object via the lifting cable 4413. When aligned with the "lift" position, the handle 434 can be rotated clockwise to lift the suspended object. When aligned with the "lock" position, the inner spring key 452, under the action of the spring force, locks the ratchet gear 443, preventing the main shaft 44 from rotating. Therefore, the handle 434 cannot be turned in either direction at this time, and the object is locked and suspended in the air.

[0058] The take-up reel 441 is connected to the main shaft 44 via a key. Clockwise rotation of the main shaft 44 takes in the steel cable, lifting the object; counterclockwise rotation releases the steel cable, lowering the object. The end of the steel cable is inserted into the body of the take-up reel 441 and secured by the cable locking screw 4414. The worm gear 442 is connected to the main shaft 44 via a key, and a lower worm gear 431 meshes with it. When the worm gear 431 is rotated via the handle 434, it drives the worm gear 442 and the take-up reel 441 to rotate. Due to the self-locking of the worm gear, the weight of the object is borne by it. Lifting and lowering the object can only be achieved by rotating the worm gear 431. Furthermore, due to the reduction ratio of the worm gear, the rotational torque of the worm gear 431 is very small, resulting in a small driving force for the handle 434, thus easily lifting objects. A ratchet 443 is connected to the main shaft 44 via a flat key, and snap ring keys 452 are provided on both sides of the ratchet 443. Under the action of spring force, the snap ring keys 452 are always pressed against the ratchet 443 to limit the rotation of the main shaft 44. A camshaft 450 is arranged between the two snap ring keys. By rotating the camshaft 450, the disengagement and engagement of the snap ring keys 452 and the ratchet 443 are controlled respectively, thereby achieving the locking state setting for lifting and suspension.

[0059] This invention utilizes a pulley assembly to connect a suspended object with a steel cable, and a take-up reel 441 to handle the cable's deployment and storage. Since the suspended object has a certain weight, its weight must be maintained throughout the lifting and lowering process, requiring a force-saving transmission device. Therefore, a worm gear transmission mechanism is specifically designed to achieve self-locking and force-saving functions. Maintaining and safely locking the object after it is suspended in position is crucial. At this point, the handle 434 must be locked and inoperable; a ratchet locking structure is used to ensure stable and safe suspension.

[0060] The lifting lug 5 includes a lifting lug connecting post 51 and a lifting lug connecting ring 52. The lifting lug connecting post 51 passes through the loading platform 6, and the bottom of the lifting lug connecting post 51 abuts against the loading platform 6. The lifting lug connecting ring 52 is located at the top of the lifting lug connecting post 51 and is fixedly connected. The other end of the steel cable 3 is connected to the lifting lug connecting ring 52.

[0061] In this embodiment, the lifting lug connecting column 51 is a column structure with a "T"-shaped cross-section. The loading platform 6 includes a hollow frame structure, and a nut is fitted onto the lifting lug connecting column 51. The end of the lifting lug connecting column 51 is located inside the loading platform 6. An I-beam support member 61 is provided in the middle of the loading platform 6. The I-beam support member 61 is a column structure made of existing I-beam material and is used to support the loading platform 6.

[0062] The parallel terminal 7 has a block structure. The ends of the two steel cables 3 are fixed to the top of the parallel terminal 7, and another steel cable 3 is fixed to the bottom of the parallel terminal 7. The steel cable 3 is fixed to the lifting roller 441.

[0063] In this embodiment, the top of the parallel terminal 7 is provided with a top through hole 71, and the bottom of the parallel terminal 7 is provided with a bottom through hole 72. The two steel cables 3 at the top of the parallel terminal 7 are fixed together and pass through the top through hole 71. The top end of the steel cable 3 at the bottom of the parallel terminal 7 passes through the bottom through hole 72 and is tied together. The top through hole 71 of the parallel terminal has a U-shaped hole structure.

[0064] There are four steel cables 3, which are connected to the four corners of the supporting platform 6 via four lifting lugs 5. The other ends of the four steel cables 3 pass through the corresponding lifting pulley rollers 14 on the four lifting pulley assemblies 1, and then converge on the steering pulley rollers 24. Two of the four steel cables 3 are connected to the end of the parallel terminal 7, and the other end of the parallel terminal 7 is connected to the lifting device 4. The lifting device 4 realizes the lifting and lowering of the suspended object, and at the same time locks it.

[0065] In actual use, the steel cable 3 includes two connecting steel cables and two lifting steel cables. The two ends of the connecting steel cables are fixed to one corner on each side of the suspended object, totaling four corners. During assembly, the steel cables 3 are first passed through the U-shaped hole at the top of the parallel terminal 7, then both ends pass through a set of pulleys in the steering pulley assembly 2, and then converge into their respective lifting pulley assemblies 1, connecting to the corner ends of the suspended object. The steel cable 3 at the lower end of the parallel terminal 7 comes from the lifting steel cable 4413 in the hoist; that is, the lifting steel cable 4413 and the steel cable 3 at the lower end of the parallel terminal 7 are the same component. There are two of them, each connected to one of the two parallel terminals 7. After being inserted into the lower hole of the parallel terminal 7 and folded back, the steel cables are secured with a locking buckle.
