Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to high-liquid overhead crane hook transportation equipment and methods. Background Technology

[0002] In industrial production, high-viscosity liquids (such as resins, syrups, lubricants, adhesives, etc.) are key raw materials or finished products, and their storage and transportation require stringent standards for equipment stability and safety. Due to the physical characteristics of these high-viscosity liquids (poor fluidity and high density), large, rigid containers with sealing functions (such as steel sealed barrels and customized storage tanks) are often used for storage in practical applications. The handling of these containers mainly relies on overhead cranes (bridge cranes, gantry cranes, etc.) in conjunction with hook assemblies. That is, the crane hooks directly hook onto the pre-set lifting lugs on the top of the container to achieve lifting and horizontal transportation of the container. This method is the mainstream means of handling high-viscosity liquid containers in current industrial scenarios.

[0003] However, existing traditional overhead crane hook handling solutions have significant technical defects, with the core problem being insufficient fixation stability, specifically manifested as follows:

[0004] Defects in the contact structure lead to low fixation reliability: The traditional way of matching the hook of the overhead crane with the container lifting lug is mostly single-point or two-point contact (such as a single hook hooking a single lifting lug, or a double hook hooking two symmetrical lifting lugs respectively). The number of contact points is small and the force is concentrated, which can only provide basic suspension support and cannot form circumferential or multi-directional limiting constraints on the container.

[0005] High viscosity liquid characteristics cause center of gravity shift and swaying: Although high viscosity liquids have lower fluidity than ordinary liquids, during container handling, the liquid inside the container will still sway slowly but continuously due to the inertial force when the crane starts and stops and the centrifugal force when turning. This causes the overall center of gravity of the container to shift dynamically with the swaying of the liquid. The single-point / two-point support structure of traditional hooks cannot counteract the eccentric force caused by the shift of the center of gravity, which in turn causes the container to swing or even rotate around the hook contact point.

[0006] Significant safety risks: As the swing amplitude of the container increases (especially in scenarios where the crane frequently starts and stops or makes long-distance turns), the fit between the hook and the lifting lug is prone to loosening. In extreme cases, the lifting lug may detach from the hook, causing the container to tip over. At the same time, the container's sealing structure may deform or fail to seal due to violent shaking, resulting in leakage of high-viscosity liquid. This not only leads to material loss but may also pollute the production environment, cause equipment corrosion, or cause safety accidents such as personnel slipping and falling.

[0007] In summary, existing traditional overhead crane hook-based methods for transporting high-liquid containers are insufficient to meet the industrial production requirements for "high stability and high safety" in high-liquid transport due to design flaws in the fixed structure and inadequate adaptation to the sloshing characteristics of high liquids. There is an urgent need for an overhead crane hook-based transport technology for high-liquid containers that can specifically address the problems of "container sloshing and unreliable fixation" in order to improve the stability of high-liquid containers during transport and reduce the risk of leakage and spillage. Summary of the Invention

[0008] The purpose of this invention is to provide a high-liquidity crane hook transportation device and method, which solves the problem of unstable hook transportation in the prior art.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A high-pressure liquid handling crane hook transport device includes a displacement seat with a lifting hole at its center. The displacement seat has transport drive modules on both sides for driving its transport. A hook assembly is located below the displacement seat, including a lifting block. Three booms are arrayed on the outer side of the lifting block, with their ends connected to lifting ropes. The lifting ropes are connected to a winding module for winding the booms. A vertical slide rod is slidably positioned at the center of the lifting block, with a top plate at its upper end. The top plate is connected to the lifting block via a lifting spring. A hook for hooking and lifting liquid cylinders is located at the lower end of the vertical slide rod. Anti-sway modules for gripping the liquid cylinders are located on both sides of the lifting block.

[0011] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0012] In one alternative: the anti-sway module includes gear side plates arrayed on the outside of the lifting block. The inner end of the gear side plate is connected to the lifting block via a connecting side rod. Each gear side plate is rotatably provided with a second gear and a first gear. A clamping frame is fixedly provided on the outside of the second gear. The lower end of the clamping frame is provided with a clamping arc plate that presses against the outside of the liquid filling cylinder. The top plate is provided with a clamping drive component that drives the clamping frame to complete the clamping.

[0013] In one alternative embodiment: the anti-sway module further includes an active anti-sway component for further locking the position of the lifting block. The active anti-sway component includes an inclined beam at the end of the boom, the inclined beam being curved upwards, and pressure rollers symmetrically arranged on both sides of the end of the inclined beam. Multiple pressure inclined plates are arrayed at the lower end of the displacement seat, and a central block is provided on the upper side of the pressure inclined plate. The central block is rotatably mounted on a rotating base shaft. An L-shaped frame is fixedly provided at the lower end of the displacement seat. Two arc-shaped guide rods are provided on the pressure inclined plate. The L-shaped frame is provided with arc-shaped sliding holes that slide and match the arc-shaped guide rods. A spring sleeve and a damper connecting the L-shaped frame and the pressure inclined plate are sleeved on the outer side of the arc-shaped guide rod.

[0014] In one alternative: the lower side of the pressure plate is provided with an arc-shaped pressure surface, and the arc-shaped pressure surface of the arc structure provides circumferential restraint to the two pressure rollers.

[0015] In one alternative: the clamping drive includes vertical bars arranged in an array on the outer side of the top plate, the outer side of the vertical bars having a rack surface, the rack surface meshing with a first gear.

[0016] In one alternative: the inner side of the vertical bar is provided with a guide sliding hole, and multiple guide sliders are arrayed on the outer side of the lifting block. The cross-sections of the guide sliders and the guide sliding holes are both T-shaped structures, and the two slide in a matching manner.

[0017] In one alternative: the winding module includes a winding roller for winding the lifting rope, the winding roller being driven by a hoisting motor unit, the outer side of the winding roller being provided with a protective shell for protection, and the inner side of the displacement seat being fixed with a guide wheel for guiding the lifting rope, the lifting rope being guided by the guide wheel.

[0018] In one alternative: the transport drive module includes two symmetrically arranged walking tracks, the upper end of the walking tracks is provided with wheel grooves, the displacement seat is symmetrically provided with walking frames on both sides, the walking frames are symmetrically provided with walking wheels on both sides, and the walking wheels are driven by a walking motor.

[0019] In one alternative: the outer side of the vertical slide bar is provided with a limiting protrusion, and the inner side of the hoisting block is provided with a limiting groove that matches the limiting protrusion, and the limiting protrusion and the limiting groove are matched.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. This invention addresses existing needs by utilizing the weight of the object itself to provide rotational kinetic energy to the clamping frame. This allows the liquid cylinder to be clamped around its sides simultaneously after being lifted, avoiding the problem of the object swaying due to single-point suspension. The self-locking structure here does not require an additional power source. When unloading, simply lowering the liquid cylinder will cause the top plate to reset under the reset of the lifting spring. Combined with the transmission of gears and racks, this will cause the alarm frame to rotate in the opposite direction, releasing the lock on the liquid cylinder.

[0022] 2. This invention improves the stability of equipment hoisting by constructing three sets of lifting ropes and three sets of booms for suspension.

[0023] 3. The present invention has a further anti-sway structure. When the liquid filling cylinder still sways after being hoisted by three ropes, that is, when the wind force is strong, the liquid filling cylinder is hoisted up so that the pressure wheel and the pressure plate press against each other. When the lower side of the pressure plate is squeezed, the damper and the spring sleeve will be compressed, thereby limiting the swaying of the liquid filling cylinder from three directions and further improving the stability of high liquid transportation.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1-7 As shown, this embodiment of the invention provides a high-liquidity crane hook transportation device, including a displacement seat 100. The displacement seat 100 has a hoisting through hole 101 at its center. The displacement seat 100 has transportation drive modules on both sides for driving its transportation. The displacement seat 100 has a hook assembly 400 below it. The hook assembly 400 includes a hoisting block 413. Three booms 408 are arranged in an array on the outer side of the hoisting block 413. The ends of the booms 408 are connected to the hoisting ropes 204. The hoisting ropes 204 are connected to a winding module for winding them. A vertical slide rod 412 is slidably provided at the center of the hoisting block 413. The upper end of the vertical slide rod 412 has a top plate 411. The top plate 411 is connected to the hoisting block 413 by a hoisting spring 410. The lower end of the vertical slide rod 412 has a hook 403 for hanging and picking up a liquid cylinder 500. The hoisting block 413 has anti-sway modules on both sides for holding the liquid cylinder 500 tightly.

[0038] The anti-sway module includes gear side plates 405 arrayed on the outside of the lifting block 413. The inner end of the gear side plate 405 is connected to the lifting block 413 through a connecting side rod 404. Each gear side plate 405 is rotatably provided with a second gear 406 and a first gear 414. A clamping frame 401 is fixedly provided on the outside of the second gear 406. The lower end of the clamping frame 401 is provided with a clamping arc plate 402 that presses tightly against the outside of the liquid cylinder 500. The top plate 411 is provided with a clamping drive component that drives the clamping frame 401 to complete the clamping. Under the clamping drive, multiple clamping frames 401 rotate synchronously toward the liquid cylinder 500, so that the clamping arc plate 402 clamps the outside of the liquid cylinder 500 from all sides, avoiding the problem of the liquid cylinder 500 shaking due to single-point lifting.

[0039] The anti-sway module also includes an active anti-sway component 300 for further locking the position of the lifting block 413. The active anti-sway component 300 includes an inclined beam 418 at the end of the boom 408, which is curved upwards. The inclined beam 418 has symmetrically arranged pressure rollers 407 on both sides of its end. Multiple pressure inclined plates 301 are arrayed at the lower end of the displacement seat 100. A central block 307 is provided on the upper side of each pressure inclined plate 301, and the central block 307 is rotatably mounted on a rotating base shaft 306. An L-shaped frame 302 is fixedly provided at the lower end of the displacement seat 100. Two arc-shaped guides are provided on the pressure inclined plates 301. The L-shaped frame 302 is provided with an arc-shaped sliding hole 304 that slides and matches the arc-shaped guide rod 305. The outer side of the arc-shaped guide rod 305 is fitted with a spring sleeve and a damper 303 that connects the L-shaped frame 302 and the pressure plate 301. When the three suspension ropes 204 are still swaying after hoisting, that is, when the wind force is large, the liquid filling cylinder 500 is hoisted up so that the pressure wheel 407 presses against the pressure plate 301. When the lower side of the pressure plate 301 is squeezed, the damper 303 will be compressed, thereby limiting the swaying of the liquid filling cylinder 500 from three directions and further improving the stability of high liquid transportation.

[0040] The lower side of the pressure plate 301 is provided with an arc-shaped pressure surface 308. The arc-shaped pressure surface 308 can circumferentially restrain the two pressure rollers 407 and restrict the rotation of the heavy object.

[0041] The clamping drive includes vertical bars 409 arrayed on the outer side of the top plate 411. The outer side of the vertical bars 409 is provided with a rack surface 417. The rack surface 417 meshes with the first gear 414. When the liquid cylinder 500 is hoisted on the hook 403, the top plate 411 is pulled downward and slides, and the vertical bars 409 also move downward. The rack surface 417 on the outer side of the vertical bars 409 drives the first gear 414 to rotate. The first gear 414 matches with the second gear 406, thereby driving the clamping frame 401 to clamp the liquid cylinder 500, thereby preventing the liquid cylinder 500 from shaking. During the unloading process, under the action of the hoisting spring 410, the vertical bars 409 will move upward. With the help of the two gears, the clamping frame 401 will rotate upward, releasing the clamping arc plate 402 from clamping the liquid cylinder 500.

[0042] The vertical bar 409 has a guide sliding hole 416 on its inner side, and multiple guide sliders 415 are arrayed on the outer side of the lifting block 413. Both the guide sliders 415 and the guide sliding hole 416 have a T-shaped cross-section and slide to match each other. In this way, when the vertical bar 409 moves up and down, the guide sliding hole 416 and the guide slider 415 match each other, making the vertical bar 409 rise and fall more smoothly and improving the structural strength.

[0043] The winding module includes a winding roller 201 for winding the lifting rope 204. The winding roller 201 is driven by the hoisting motor unit 200. The outer side of the winding roller 201 is provided with a protective shell 202 for protection. The inner side of the displacement seat 100 is fixed with a guide wheel 203 for guiding the lifting rope 204. The lifting rope 204 is guided by the guide wheel 203. Here, with three arrays of lifting ropes 204 and three arrays of booms 408, this solution is more stable than the traditional double-strand or single-strand lifting rope.

[0044] The transport drive module includes two symmetrically arranged walking tracks 103. Each walking track 103 has a wheel groove 104 at its upper end. The displacement seat 100 has symmetrically arranged walking frames 105 on both sides, and walking wheels 102 are symmetrically arranged on both sides of each walking frame 105. The walking wheels 102 are driven by a walking motor, which rotates the walking wheels 102, allowing the displacement seat 100 to move smoothly at high altitudes. The dual-track transport provides better stability.

[0045] The vertical slide bar 412 has a limiting protrusion on its outer side, and the lifting block 413 has a limiting groove on its inner side that matches the limiting protrusion. The limiting protrusion and the limiting groove match each other, so that the vertical slide bar 412 and the lifting block 413 will not rotate relative to each other.

[0046] Working principle: The displacement seat 100 is transferred to the top of the liquid filling cylinder 500 by the transport drive module. Then, the hook 403 is lowered by the winding module, and the hook 403 hooks the hanging ring on the liquid filling cylinder 500. Then, the hook 403 is lifted by the winding module. During the lifting process, the liquid filling cylinder 500 will drive the hook 403 and the top plate 411 to move down. The vertical bar 409 on the outer side of the top plate 411 will also move down. The rack surface 417 on the outer side of the vertical bar 409 drives the first gear 414 to rotate. 414 matches the second gear 406, thereby driving the clamping frame 401 to clamp the liquid cylinder 500, thus preventing the liquid cylinder 500 from shaking. If the wind is strong during transportation, causing the liquid cylinder 500 to shake, the liquid cylinder 500 is lifted up so that the pressure roller 407 presses against the pressure plate 301. When the lower side of the pressure plate 301 is squeezed, the damper 303 is compressed, thereby limiting the shaking of the liquid cylinder 500 from three directions, further improving the stability of high-volume transportation.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
