[0037] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0038] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] like Figures 1 to 2 As shown, the present invention provides a full-revolving sling, comprising:

[0040] A balance beam 1, with movable pulley lifting ears 2 arranged on both sides of its upper surface, for connecting with the movable pulley on the overhead travelling crane through a steel wire rope, and a connecting piece 7 arranged at the bottom center of the balance beam 1;

[0041] A slewing mechanism 3 connected to the balance beam 1 via a connecting member 7;

[0042] A spatial hanging point structure 4, which is connected to the slewing mechanism 3 and realizes slewing motion through the slewing mechanism 3;

[0043] The bottom distribution beam 5 is used to connect the hoisted objects, and the bottom distribution beam 5 is connected to the space hanging point structure 4 through a plurality of distribution slings 6.

[0044] In the above technical solution, the movable pulley lifting lug 2 is a pin-shaft lug plate structure connected to the movable pulley on the overhead crane. The balance beam 1 is a structure that evenly distributes the lifting load to multiple sets of movable pulley lifting points, which is generally a box beam structure. The spatial hanging point structure 4 is generally a pin-shaft lug plate structure, and the pin-shaft lug plate structure is arranged in a spatial figure eight along the direction of the distribution sling 6. The distribution sling 6 is a cable-like structure used to connect the spatial hanging point structure 4 and the bottom distribution beam 5, which is generally a steel wire rope. The bottom distribution beam 5 is a rigid frame, a structure used to connect to the hoisted objects.

[0045] When the overhead crane moves along the bridge cables, the entire hoist moves with the overhead crane. During the movement, the hoist is designed with a single lifting point along the bridge and is connected to the overhead crane lifting system with a pin shaft, so that it can realize plane rotation along the bridge. Due to the single lifting point structure along the bridge, it can adapt to the uphill and downhill climbing angles that change constantly during the movement of the overhead crane. The hoisted objects will always remain in a horizontal state and the force structure is reasonable.

[0046] The gear-type full-rotation structure can achieve a full rotation of 360 degrees in a plane compared to the traditional winch pulling method. The rotating structure and the sling balance beam 1 adopt a separate independent modular design and are connected by a connector 7 to facilitate production and manufacturing.

[0047] A plurality of distribution slings 6 form a three-dimensional spatial suspension structure, which can well adapt to the connection angle of the spatial cable structure between the balance beam 1 and the bottom distribution beam 5, and prevent the steel wire rope from being scratched by the sharp edge of the ear plate, causing the local bending stress of the steel wire rope to be excessive and break, which may bring safety hazards.

[0048] In another technical solution, Figure 3As shown, the slewing mechanism 3 includes a motor 8, a rotating shaft 9, a slewing pinion 10, a slewing gear 11 and a slewing beam shaft 12. The slewing beam shaft 12 is horizontally fixed to the connecting member 7. The slewing gear 11 is connected to the slewing beam shaft 12 through a bearing key. The slewing pinion 10 is meshed with the slewing gear 11 and driven to rotate by the motor 8. The rotating shaft 9 is vertically connected to the center of the slewing gear 11. The rotating shaft 9 is connected to the space hanging point structure 4. The motor 8 and the slewing pinion 10 are each provided in pairs and are respectively located on opposite sides of the slewing gear 11.

[0049] In the above technical solution, the rotating small gear 10 is driven by the rotating motor 8 to drive the rotating large gear 11 to move. The rotating large gear 11 is connected to the rotating beam shaft 12 by a bearing key to achieve relative rotation. The rotating large gear 11 drives the rotating shaft 9 to rotate, thereby driving the objects to be hoisted below to rotate. The rotating shaft 9 and the motor 8 form a separate system, and there is no need to open a hole on the sling balance beam 1, which greatly simplifies the structural system of the balance beam 1.

[0050] In another technical solution, the spatial hanging point structure 4 is a pin-shaft ear plate structure, which is arranged in an eight-shaped shape in space along the direction of the distribution sling 6. The bottom distribution beam 5 has four hanging points formed by pin-shaft ear plates at its four corners, and the spatial hanging point structure 4 is located at the center of the bottom distribution beam 5.

[0051] In the above technical solution, the balance beam 1 is a beam body, and the bottom distribution beam 5 is a flat square frame. Four hanging points are set at the four corners of the bottom distribution beam 5. Four distribution slings 6 are connected to the bottom distribution beam 5 in an eight-shaped shape from the space hanging point structure 4 directly above the center of the bottom distribution beam 5 to realize three-dimensional space suspension.

[0052] In another technical solution, the connecting member 7 is a pair of ear plates, and the pair of ear plates are fixedly connected to the slewing beam shaft 12 of the slewing mechanism 3 .

[0053] In another technical solution, Figures 4 to 7 As shown, the space hanging point structure 4 includes:

[0054] The connecting body 401 is a structure with a horizontal upper surface and a pair of symmetrical side surfaces in an eight-shaped shape. The upper portion of the side surface of the connecting body 401 is arc-shaped and the lower portion is linear;

[0055] A connecting block 402, the center of the upper end of which is fixedly connected to the lower end of the rotating shaft 9 of the rotary mechanism 3, the lower end of the connecting block 402 is fixedly connected to the upper surface of the connecting body 401, the central axis of the connecting block 402 coincides with the central axis of the connecting body 401, the lower part of the connecting block 402 has a horizontally penetrating channel 403, the center of the channel 403 is provided with a pin 404 along its width direction, and its two ends are fixed to the connecting block 402;

[0056] The hanging plates 405 are a pair, and the shape of the hanging plates 405 is completely consistent with the side shape of the connecting body 401. In the initial state, the pair of hanging plates 405 are arranged closely against the side surfaces of the connecting body 401. The upper ends of the pair of hanging plates 405 are also fixedly connected with a pair of horizontal rotating plates 406, and the ends of the pair of rotating plates 406 are sleeved on the pin shaft 404 and are arranged to rotate freely around the pin shaft 404. Both sides of the hanging plates 405 along the width direction of the connecting body 401 protrude outside the connecting body 401, and the rotating plates 406 cooperate with the channel 403, and the height direction of the channel 403 is arranged not to interfere with the rotation of the rotating plates 406. The lower ends of both sides of the hanging plates 405 along the width direction of the connecting body 401 are recessed upward to form notches 407, and a connecting shaft 408 is penetrated in the notch 407. The distribution sling 6 is sleeved and connected to the connecting shaft 408. The lower ends of the pair of hanging plates 405 are symmetrical and relatively connected with four distribution slings 6;

[0057] The driving wheels 409 are a pair and are symmetrically arranged in the connecting body 401 relative to the central axis of the connecting body 401. The outer edges of the adjacent semicircles of the driving wheels 409 have mutually meshing gears. The outer edges of the other semicircles of the driving wheels 409 are fixed with adjusting rods 410. The outer ends of the adjusting rods 410 are respectively passed through the interior of the connecting body 401 and pressed against the lower part of the pair of hanging plates 405. The center of one of the driving wheels 409 is fixedly connected and driven to rotate through the driving shaft 411 of the motor. The center of the other driving wheel 409 is fixedly sleeved on the rotating shaft 412. The two ends of the rotating shaft 412 are connected through bearings fixed in the connecting body 401. The connecting body 401 has a space for the adjusting rod 410 to rotate up and down.

[0058] The positioning mechanism is a pair and is respectively located on both sides of the width direction of the connecting body 401. The positioning mechanism includes a pair of positioning balls 413, a pair of limiting plates 414, a limiting block 416 and a cushion block 415. The limiting block 416 slides up and down through a slide groove arranged on the surface of the connecting body 401. The limiting block 416 is driven to slide up and down by the lifting cylinder at the bottom. The upper surface of the limiting block 416 has a downwardly concave groove. The lower ends of the pair of positioning balls 413 are both fitted in the groove. The lower ends of the pair of limiting plates 414 are also fitted in the groove and the pair of limiting plates 414 are located between the pair of positioning balls 413. The interval space between the pair of limiting plates 414 in the groove is filled by the cushion block 415. The lower part of the positioning ball 413 is spherical, and the upper part is close to the adjacent hanging plate 405 side as an arc surface close to the upper arc of the hanging plate 405. The limiting plate 414 is set close to and against the positioning ball 413.

[0059] In the above technical scheme, the space hanging point structure 4 is used to connect the slewing mechanism 3, and the slewing mechanism 3 drives the hoisted objects connected to the bottom distribution beam 5 below to realize slewing motion. The bottom distribution beam 5 is a square structure, which is connected to the space hanging point structure 4 through four distribution slings 6 at four corners. The space hanging point structure 4 is always located above the center of the bottom distribution beam 5. According to the different sizes of the bottom distribution beam 5, the angle between the distribution sling 6 and the space hanging point structure 4 needs to be set to be adjustable to adapt to the bottom distribution beams 5 of different sizes to lift hoisted objects of different sizes. This technical scheme designs a new space hanging point structure 4 to meet the adjustment of the angle between it and the distribution sling 6 to adapt to the construction of various different construction environments. Figures 4 to 7 The left-right direction shown is the length direction.

[0060] In the initial state, if Figure 6As shown, it is an internal cross-sectional view of the connecting body 401, the adjusting rod 410 just extends to the surface of the connecting body 401, the hanging plate 405 is close to the outer side of the connecting body 401, and the rotating plate 406 is horizontally close to the lower bottom surface of the channel 403. At this time, the distribution sling 6 is mounted on the connecting shaft 408 and then connected to the bottom distribution beam 5. The angle is the minimum inclination angle under various construction conditions. When it is necessary to adjust the angle increase, the left driving wheel 409 drives the left driving wheel 409 to rotate through the built-in motor via the driving shaft 411, and the left adjusting rod 410 rotates to the left and upward, thereby pushing the left hanging plate 405 to rotate upward and to the left, thereby increasing the angle of the distribution sling 6. In this process, since the adjacent pair of driving wheels 409 are engaged through the gears close to the center of the connecting body 401, the right driving wheel 409 rotates in the opposite direction to the left driving wheel 409, and the right adjusting rod 410 rotates to the right and upward, thereby pushing the right hanging plate 405 to rotate upward and to the right. Since the pair of driving wheels 409 have exactly the same structure and are symmetrically arranged relative to the central axis of the connecting body 401, the rotation angle and height of the pair of hanging plates 405 on both sides are exactly the same, thereby achieving symmetrical adjustment of the angle of the distribution sling 6, and the angle of the hoisted objects can also remain unchanged. Figure 7 The angle shown is after adjustment.

[0061] Since the connection body 401 does not need to be set up with a larger structure, and the hanging plate 405 must be able to adapt to the larger size of the underlying distribution beam 5 connected through the distribution sling 6, the hanging plate 405 protrudes from the connection body 401 on both sides along the width direction of the connection body 401. After the angle adjustment is completed, the positioning of the entire hanging plate 405 is achieved through the positioning of the protruding parts. The positioning mechanism is fixed on the side surfaces on both sides of the width direction of the connection body 401, and is used to further position the position of the hanging plate 405 after the angle of the hanging plate 405 is adjusted. Otherwise, the tight positioning and limiting of the adjustment rod 410 alone is not stable enough, and the hanging plate 405 is easily damaged under the large lifting force of the distribution sling 6. In the initial state, if Figure 4As shown, the surface of the connecting body 401 is provided with a slide groove, which allows the limit block 416 to slide up and down therein. The limit block 416 slides up and down and is driven by a lifting cylinder. Two symmetrical lifting cylinders can be provided as needed, and the lifting cylinder is fixed to the connecting body 401. The lower part of the positioning ball 413 is spherical and can rotate appropriately in the groove of the limit block 416, so that the arc surface of the upper part of the positioning ball 413 is always close to the inner side of the arc shape of the hanging plate 405, and the limit plate 414 is freely located in the groove and can move left and right. After the movement, the interval space between a pair of limit plates 414 is filled with a gasket 415. A plurality of gaskets 415 of different thicknesses can be provided to meet the requirement of completely filling the interval space. The height of the gasket 415 can be set to be only in the groove, or it can be set to protrude outside the groove and be the same as or lower than the height of the limit plate 414, as long as it can fully meet the requirement of fixing the position of a pair of limit plates 414. Figure 5 As shown, it is a schematic diagram of a pair of hanging plates 405 after the angle is adjusted. The limit block 416 is lifted upward by the lifting cylinder, and the angle of the lower part of the positioning ball 413 is appropriately adjusted. Then, the position is positioned by a pair of limit plates 414 and cushion blocks 415 to ensure that the position of the pair of hanging plates 405 is stable.

[0062] In another technical solution, a hanging ring is provided at the end of the adjusting rod 410, and a plurality of hooks are provided on the hanging plate 405 along its height direction, which cooperate with the hanging ring, and the position of the hook does not interfere with the space for the adjustment rod 410 to move. After the angle is adjusted, the hanging plate 405 is initially positioned by hanging the hook on the hanging ring.

[0063] In another technical solution, a positioning wedge is provided in the space between the lower surface of the rotating plate 406 and the lower surface of the channel 403. The rising angle of the rotating plate 406 is different according to the adjustment angle, so the positioning wedge is provided in the space below the rotating plate 406 to ensure the positioning limit of the rotating plate 406.

[0064] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
