Description

Technical Field

[0001] The present invention belongs to the technical field of lifting equipment, and in particular relates to a special floating lifting device for gear motors. Background Art

[0002] In the current industrial landscape, the issue of hoisting during motor transportation and assembly has long been a concern. Traditional hoisting fixtures utilize a single hoist connected to a ring, but this design has significant drawbacks. In practice, this type of hoisting fixture can easily cause noticeable shaking in the motor, reducing stability during the lifting process and making motor installation difficult and inconvenient. Consequently, existing technologies suffer from poor stability during hoisting. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a special floating hoist for gear motors, which solves the problem of poor stability during the hoisting process in the existing technology.

[0004] The purpose of this disclosure can be achieved through the following technical solutions:

[0005] A special floating lifting device for a gear motor includes a lifting ring fixed to the gear motor;

[0006] There are two lifting rings, and the two lifting rings are fixedly installed on both sides of the upper end of the gear motor;

[0007] A pressing block for placing on the upper end surface of the gear motor is provided between the two lifting rings, a connecting seat is fixedly connected to the pressing block, a limiting frame with an open lower end is provided just above the connecting seat, a horizontally placed rotating shaft is fixed to the lower end of the limiting frame, and the two lifting rings are symmetrically placed about the central axis of the rotating shaft;

[0008] A pair of first connecting bars are sleeved on the rotating shaft and are rotatably connected thereto. The two first connecting bars are respectively located on both sides of the rotating shaft. The ends of the first connecting bars away from the rotating shaft are rotatably hinged to the second connecting bars, and the ends of the second connecting bars away from the first connecting bars are rotatably hinged to the connecting base.

[0009] The second connecting bars correspond to the lifting rings one by one, and the second connecting bars are all provided with ring chains, and the ends of the ring chains away from the second connecting bars are detachably connected to the corresponding lifting rings.

[0010] The principles and effects of the above technical solution are as follows:

[0011] During hoisting, the limit frame is hooked on equipment such as a crane or a hoist. When the hoist moves upward, the limit frame drives the rotating shaft and the first connecting bar to move upward near the rotating shaft end, so that the angle between the two first connecting bars is reduced. At the same time, the first connecting bar drives the second connecting bar, so that the two second connecting bars push the connecting seat and the clamping block, so that the clamping block presses the gear motor downward, thereby ensuring that the gear motor will not shake greatly during the hoisting process, thereby improving the stability during the hoisting process; the hoist has a simple structure and a compact appearance. The hoist will not collide with the box when the gear motor is packed. After the gear motor is packed, the ring chain and the lifting ring can be separated.

[0012] A spring is provided between the limit frame and the connecting seat, and movable bolts are fixed at both ends of the spring. The movable bolt at the upper end of the spring is threadedly connected to one end of any first connecting bar close to the rotating shaft, and the movable bolt at the lower end of the spring is threadedly connected to the connecting seat;

[0013] The second connecting bars are each provided with a circular through hole coaxially arranged with the rotating shaft;

[0014] Each ring chain includes at least two pull rings connected to each other, and the lifting rings near the second connecting bar end of the ring chain are nested with the round through holes;

[0015] There are multiple circular through holes, and the multiple circular through holes are evenly distributed along the axis direction of the second connecting bar;

[0016] The lifting rings of the ring chain close to the second connecting bar are each provided with a first notch groove for the second connecting bar to pass through;

[0017] The pull rings near the lifting rings in the chain are each provided with a second notch groove for the lifting rings to pass through;

[0018] A rotating shaft coaxially arranged with the rotating shaft is fixed to each end of the first connecting bar away from the rotating shaft, and the rotating shaft passes through the corresponding second connecting bar and is rotatably engaged with the second connecting bar;

[0019] A pair of rectangular grooves are opened at the upper end of the connecting seat, and a fixed shaft is fixed on the connecting seat and is placed coaxially with the rotating shaft. The fixed shaft passes through the two rectangular grooves, and the two second connecting strips are located in the two rectangular grooves away from the ends of the first connecting strip. The fixed shaft passes through the second connecting strip and is rotatably connected to it.

[0020] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0021] Fixed connection: refers to the process of connecting two separate profiles or parts into a complex part or component using fasteners such as screws, bolts and rivets.

[0022] A rotary joint is a mechanical connection device that allows two parts to rotate relative to each other around an axis.

[0023] Beneficial effects of the present disclosure:

[0024] 1. When the spreader moves upward, the limit frame drives the rotating shaft and the first connecting bar to move upward close to the rotating shaft end, so that the angle between the two first connecting bars is reduced. At the same time, the first connecting bar drives the second connecting bar, so that the two second connecting bars push the connecting seat and the pressing block, so that the pressing block presses the gear motor downward, thereby ensuring that the gear motor will not shake significantly during the lifting process and improving the stability of the lifting process; the spreader has a simple structure and a compact appearance. The spreader will not collide with the box when the gear motor is packed. After the gear motor is packed, the chain and the lifting ring can be separated;

[0025] 2. Through the setting of spring and movable bolt, after the lifting and transportation is completed, the first connecting bar and the second connecting bar can be pulled to retract and reset under the action of the spring force;

[0026] 3. By setting multiple round through holes on the second connecting bar, the round through holes at appropriate positions can be selected to connect with the ring chain according to the sizes of gear motors of different specifications, so as to facilitate the connection of the lifting rings on gear motors of different specifications and improve the flexibility and adaptability of the sling.

[0032] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0033] Combined here Figures 1 to 4The following describes an embodiment of a special floating sling for gear motors. Specifically, the special floating sling for gear motors is constructed as a split structure, which includes components such as a lifting ring 100, a clamping block 200, a connecting seat 300, a limiting frame 400, a rotating shaft 401, a first connecting bar 500, a second connecting bar 600, and a chain 700. During lifting, the limiting frame 400 is hooked on equipment such as a crane or a hoist. When the sling moves upward, the limiting frame 400 drives the rotating shaft 401 and the first connecting bar 500 to move upward near the end of the rotating shaft 401, thereby reducing the angle between the two first connecting bars 500. At the same time, the first connecting bar 500 drives the second connecting bar 600, causing the two second connecting bars 600 to push the connecting seat 300 and the clamping block 200, causing the clamping block 200 to press the gear motor 900 downward, thereby ensuring that the gear motor 900 does not shake significantly during lifting, thereby improving stability during lifting.

[0034] The sling has a simple structure and a compact appearance. The sling will not collide with the box when the gear motor 900 is packed. After the gear motor 900 is packed, the ring chain 700 and the lifting ring 100 can be separated.

[0035] Please refer to Figures 1 to 4 , a gear motor floating special lifting device, including a lifting ring 100 fixed on the gear motor 900;

[0036] There are two lifting rings 100, and the two lifting rings 100 are fixedly installed at both sides of the upper end of the gear motor 900;

[0037] A pressing block 200 is provided between the two lifting rings 100 for placement on the upper end surface of the gear motor 900. A connecting seat 300 is fixedly connected to the pressing block 200. A limiting frame 400 with an open lower end is provided directly above the connecting seat 300. A horizontally placed rotating shaft 401 is fixed to the lower end of the limiting frame 400. The two lifting rings 100 are symmetrically placed about the central axis of the rotating shaft 401.

[0038] A pair of first connecting bars 500 are sleeved on the rotating shaft 401 and are rotatably connected thereto. The two first connecting bars 500 are respectively located on both sides of the rotating shaft 401. The ends of the first connecting bars 500 away from the rotating shaft 401 are both rotatably hinged to the second connecting bars 600. The ends of the second connecting bars 600 away from the first connecting bars 500 are both rotatably hinged to the connecting base 300.

[0039] The second connecting bars 600 correspond to the lifting rings 100 one by one. Each of the second connecting bars 600 is provided with a ring chain 700. The ends of the ring chains 700 away from the second connecting bars 600 are detachably connected to the corresponding lifting rings 100.

[0040] The lifting ring 100 is generally made of steel or other metal alloys to have good load-bearing capacity and durability. Its surface can be galvanized or sprayed with an anti-corrosion coating to increase corrosion resistance.

[0041] The pressing block 200 is usually made of metal material; preferably, a gasket made of elastic rubber material is fixedly attached to the side surface of the pressing block 200 that contacts the gear motor 900, which can reduce damage to the gear motor 900 during the pressing process.

[0042] The first connecting bar 500 may be made of high-strength alloy steel or stainless steel to ensure load-bearing capacity and durability, and may also be subjected to rust-proof treatment such as chrome plating or oxidation treatment to increase surface hardness and corrosion resistance.

[0043] The sling of the present application is used in conjunction with a crane or hoist in the prior art. Before hoisting, the sling is placed above the gear motor 900 to be hoisted, the pressing block 200 is placed on the upper end surface of the gear motor 900, and the ring chain 700 is connected and installed with the corresponding lifting ring 100;

[0044] During hoisting, the limit frame 400 is hooked on a crane or other equipment. When the hoist moves upward, the limit frame 400 drives the rotating shaft 401 and the first connecting bar 500 to move upward near the end of the rotating shaft 401, so that the angle between the two first connecting bars 500 is reduced. At the same time, the first connecting bar 500 drives the second connecting bar 600, so that the two second connecting bars 600 push the connecting seat 300 and the pressing block 200, so that the pressing block 200 presses the gear motor 900 downward, thereby ensuring that the gear motor 900 will not shake significantly during the hoisting process, thereby improving the stability during the hoisting process;

[0045] The sling has a simple structure and a compact appearance. The sling will not collide with the box when the gear motor 900 is packed. After the gear motor 900 is packed, the ring chain 700 and the lifting ring 100 can be separated.

[0046] A spring 800 is provided between the limit frame 400 and the connecting seat 300, and a movable bolt 801 is fixed at both ends of the spring 800. The movable bolt 801 at the upper end of the spring 800 is threadedly connected to one end of any first connecting bar 500 close to the rotating shaft 401, and the movable bolt 801 at the lower end of the spring 800 is threadedly connected to the connecting seat 300; during hoisting, the first connecting bar 500 drives the second connecting bar 600 to press the connecting seat 300 and the clamping block 200 downward on the gear motor 900, and the distance between the end of the first connecting bar 500 close to the rotating shaft 401 and the connecting seat 300 increases, and pulls the spring 800 to extend; when the hoisting and transportation is completed, the spring 800 can pull the first connecting bar 500 and the second connecting bar 600 to reset and retract under the action of the elastic force of the spring.

[0047] The second connecting bars 600 are each provided with a round through hole 601 coaxially arranged with the rotating shaft 401;

[0048] The ring chain 700 includes at least two pull rings connected to each other, and the lifting rings 100 of the ring chain 700 close to the second connecting bar 600 are nested with the round through holes 601; by nesting the pull rings at the upper end of the ring chain 700 with the round through holes 601 on the second connecting bar 600, the connection between the ring chain 700 and the second connecting bar 600 can have a certain degree of automation, so as to facilitate adaptive adjustment of the layout direction of the ring chain 700 when lifting gear motors 900 of different sizes.

[0049] In order to facilitate the hoisting of gear motors 900 of various specifications and different sizes, a plurality of round through holes 601 are provided, and the plurality of round through holes 601 are evenly distributed along the axis direction of the second connecting bar 600;

[0050] The lifting ring 100 at the end of the ring chain 700 close to the second connecting bar 600 is provided with a first notch groove 701 for the second connecting bar 600 to pass through; through the arrangement of multiple round holes 601 and the first notch groove 701, the round through holes 601 at appropriate positions can be selected according to the size of the gear motor 900 of different specifications to connect with the ring chain 700, so as to facilitate the connection of the lifting ring 100 on the gear motor 900 of different specifications, thereby improving the flexibility and adaptability of the sling.

[0051] In order to facilitate the connection between the ring chain 700 and the ring 100, a second notch groove 702 for the ring 100 to pass through is opened on the pull ring of the ring chain 700 close to the ring 100; the opening of the second notch groove 702 facilitates the connection or separation of the ring chain 700 and the ring 100.

[0052] A rotating shaft 501 coaxially arranged with the rotating shaft 401 is fixed to each end of the first connecting bar 500 away from the rotating shaft 401. The rotating shaft 501 passes through the corresponding second connecting bar 600 and is rotatably engaged therewith, thereby realizing a rotatable hinge connection between the first connecting bar 500 and the second connecting bar 600.

[0053] Preferably, a circular groove is provided on the peripheral wall of the rotating shaft 501, and the second connecting bar 600 is sleeved in the circular groove. The setting of the circular groove enables the rotating shaft 501 and the second connecting bar 600 to be rotatably connected, thereby preventing the second connecting bar 600 from sliding off the rotating shaft 501 during the hoisting process.

[0054] The present application also provides another connection method between the rotating shaft 501 and the second connecting bar 600, in which the rotating shaft 501 passes through the second connecting bar 600 and is rotatably connected thereto, and the rotating shaft 501 passes through the peripheral wall of the end of the second connecting bar 600 and is provided with threaded teeth, on which a nut is threadedly connected. When the nut is tightened, it fits into the side wall of the second connecting bar 600 away from the first connecting bar 500, thereby preventing the second connecting bar 600 from slipping off the rotating shaft 501 during lifting.

[0055] A pair of rectangular grooves 301 are provided at the upper end of the connecting seat 300, and a fixed shaft 302 is fixed on the connecting seat 300 and is placed coaxially with the rotating shaft 401. The fixed shaft 302 passes through the two rectangular grooves 301, and the two second connecting bars 600 are located in the two rectangular grooves 301 away from the ends of the first connecting bar 500. The fixed shaft 302 passes through the second connecting bar 600 and is rotatably connected to it; the rotational hinge between the second connecting bar 600 and the connecting seat 300 is realized, while ensuring the stability of the connection.
