Description

Technical Field

[0001] This invention relates to the field of hoisting equipment technology, and in particular to a hoisting device and hoisting equipment. Background Technology

[0002] Lifting devices are mechanical equipment used for lifting, raising, and transferring materials. They are widely used in port loading and unloading, logistics warehousing, construction, factory production lines, and heavy equipment installation. Their basic components include a lifting mechanism, lifting ropes, and lifting tools. By rotating the winch rollers to raise and lower the slings, the height of the materials can be adjusted and the materials can be transferred in space. Depending on the application requirements, lifting devices can be fixed structures or installed on mobile base frames to form a hoistable lifting system.

[0003] During the use of lifting equipment that can lift materials for moving and transferring, although the lifting device can be moved above the material, the fixed lifting point and the fixed point of the lifting rope on the material will be somewhat misaligned, making it difficult to align accurately. At this time, the lifting rope is in an inclined state, which causes the material to sway and swing when lifted, affecting the placement and positioning after being lifted and received, and posing a safety hazard.

[0004] Based on this, the present invention designs a hoisting device and hoisting equipment to solve the above problems. Summary of the Invention

[0005] In view of the problem that the lifting point and the material fixing point are difficult to align completely when lifting materials, which causes the material to sway when lifted, the present invention is proposed.

[0013] When the winch roller initially rewinds, it drives the universal slide to slide in all directions on the movable platform, aligning the lifting mechanism with the material fixing point. When the winch roller continues to rewind and lift the material, the overall weight of the lifting mechanism increases, causing the universal slide to press down on the movable platform and contact and lock with the first locking block.

[0014] As a preferred embodiment of the hoisting device of the present invention, the transmission component includes a servo motor disposed outside the hoisting frame, a drive gear disposed at the end of the servo motor, a driven gear disposed outside the hoisting frame, the drive gear being connected to the driven gear via a transmission chain belt, a first bevel tooth disposed at the end of the driven gear, and an extension shaft extending outside the hoisting frame disposed at the end of the winch roller, with a second bevel tooth disposed at the end of the extension shaft.

[0015] In a preferred embodiment of the hoisting device of the present invention, the number of teeth of the first bevel tooth is less than the number of teeth of the second bevel tooth, the servo motor is centrally located, and a counterweight is provided on the side of the lifting frame away from the transmission chain.

[0017] As a preferred embodiment of the hoisting device of the present invention, a positioning cylinder is provided in the middle of the universal slide, the sling extends downward through the positioning cylinder, and a cable hole is provided in the middle of the movable platform, the cable hole corresponding to the positioning cylinder.

[0018] As a preferred embodiment of the hoisting device of the present invention, the movable platform is provided with a universal groove on its exterior. The universal groove is an annular groove and the bottom surface of the universal groove is a symmetrical inclined surface that tends towards the center.

[0019] As a preferred embodiment of the hoisting device of the present invention, the fixed platform has a fixing hole on its outside, the movable platform has a support pin on its outside, the support pin moves within the fixing hole, and a support spring is provided within the fixing hole.

[0020] As a preferred embodiment of the hoisting device of the present invention, a second locking block is also provided on the outside of the fixed platform. Friction plates are provided at the ends of the first locking block and the second locking block. The movable platform has a through first locking groove and a second locking groove, and the first locking block and the second locking block pass through the first locking groove and the second locking groove respectively.

[0021] The present invention also provides a hoisting device.

[0022] Including hoisting and erecting the frame;

[0023] The hoisting mechanism is installed inside the hoisting frame;

[0024] The hoisting frame is mounted on the hoisting stand.

[0025] As a preferred embodiment of the hoisting equipment of the present invention, the hoisting mechanism includes a movable beam frame disposed inside the hoisting frame, a first motor disposed outside the movable beam frame, a first transmission belt disposed at the end of the first motor, the hoisting frame disposed outside the movable beam frame, the first transmission belt being connected to the hoisting frame, a second motor disposed outside the hoisting frame, a second transmission belt disposed at the end of the second motor, and the second transmission belt being connected to the movable beam frame.

[0026] The beneficial effects of the hoisting device and hoisting equipment of the present invention are as follows:

[0027] 1. This invention mounts the entire lifting mechanism on a universal slide, and uses a vertically mounted servo motor and counterweight to keep the center of gravity of the lifting mechanism balanced and centered. During lifting, the tension of the winch roller during initial winding causes the entire lifting mechanism to slide toward the fixed point where the rope is fixed to the material. When the material is not lifted, the lifting point is automatically adjusted to align with the fixed point of the material, avoiding the situation where the lifting rope is skewed and the material shakes significantly when it leaves the ground, eliminating safety hazards, and facilitating subsequent positioning, unloading and placement.

[0028] 2. This invention uses a fixed platform and a liftable movable platform supported by a support spring above the fixed platform. When no material is being lifted, the universal slide is in an unlocked state, allowing it to self-align or center and reset. Only when the material is being lifted, the weight of the material causes the movable platform to descend, after which the locking block contacts and locks the universal slide, ensuring that the universal slide will not slide during the lifting process and guaranteeing stability during the lifting process.

[0042] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0044] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0045] Example 1, referring to Figures 1 to 5 This is the first embodiment of the present invention. This embodiment provides a hoisting device and hoisting equipment, which can realize the function that before hoisting materials, the hoisting device can automatically slide to align with the fixed point of the materials by lifting and sliding. It includes a hoisting frame 1.

[0046] Furthermore, the hoisting mechanism 2, which is movably connected to the top of the hoisting frame 1, is connected to the self-locking mechanism 3, which is installed at the bottom of the hoisting mechanism 2.

[0047] Furthermore, the hoisting mechanism 2 includes a transmission component 21 installed at the top of the hoisting frame 1, a lifting component 22 installed at the bottom of the transmission component 21, and a self-adjusting component 23 installed at the bottom of the lifting component 22;

[0048] Furthermore, the lifting component 22 includes a lifting frame 221 installed at the top of the lifting frame 1. A winch roller 222 is rotatably connected inside the lifting frame 221 through a shaft hole. A sling 224 for lifting is fixedly wound on the outer wall of the winch roller 222. The end of the sling 224 is used to install a hook, clamp, or other fixing device.

[0049] Furthermore, the self-adjusting component 23 includes a universal slide 231 installed at the bottom of the lifting frame 221, and a plurality of universal balls 234 are installed at the bottom of the universal slide 231;

[0050] Furthermore, the self-locking mechanism 3 includes a fixed platform 31 installed on the top of the hoisting frame 1, a movable platform 32 that can be raised and lowered is movably connected to the top of the fixed platform 31, and a plurality of first locking blocks 311 passing through the movable platform 32 are also installed on the top of the fixed platform 31.

[0051] Furthermore, when the winch roller 222 initially rewinds, it drives the universal slide 231 to slide universally on the movable platform 32, aligning the lifting mechanism 2 with the material fixing point. When the winch roller 222 continues to rewind and lift the material, the overall weight of the lifting mechanism 2 increases, causing the universal slide 231 to press down on the movable platform 32 and contact and lock with the first locking block 311.

[0052] Specifically, the transmission component 21 includes a servo motor 211 disposed outside the lifting frame 221. The end of the servo motor 211 is provided with a power gear 212. The outside of the lifting frame 221 is provided with a driven gear 214. The power gear 212 is connected to the driven gear 214 through a transmission chain belt 213. The end of the driven gear 214 is provided with a first bevel tooth 215. The end of the winch roller 222 is provided with an extension shaft extending outside the lifting frame 221. The end of the extension shaft is provided with a second bevel tooth 216.

[0053] Furthermore, the transmission component 21 includes a servo motor 211 mounted on the top of the lifting frame 221. A power gear 212 is mounted on the end of the servo motor 211. A driven gear 214 is mounted on the top of one side of the lifting frame 221 via a bearing. The power gear 212 is connected to the driven gear 214 via a transmission chain 213. A first bevel tooth 215 is mounted on the lower end of the driven gear 214, which is coaxially connected to and rotates synchronously with the driven gear 214. An extension shaft extending out of the lifting frame 221 is mounted on the end of the hoisting roller 222. A second bevel tooth 216 meshing with the first bevel tooth 215 is mounted on the end of the extension shaft.

[0054] Furthermore, the number of teeth of the first bevel tooth 215 is less than the number of teeth of the second bevel tooth 216, the servo motor 211 is centrally located, and a counterweight 223 is provided on the side of the lifting frame 221 away from the transmission chain 213.

[0055] It should be noted that the number of teeth of the first bevel tooth 215 is less than the number of teeth of the second bevel tooth 216. When the servo motor 211 is driving, the torque can be amplified by the bevel teeth, which is convenient for the hoist to lift the material. The servo motor 211, which is centrally located, and the counterweight 223 on the lifting frame 221 can keep the center of gravity of the hoisting mechanism 2 in the center and make the weight distribution of the hoisting mechanism 2 in balance. In actual use, the initial offset may be in any direction. Therefore, a universal sliding block 231 is provided for self-adjustment. The slidable hoisting mechanism 2 has a central center of gravity and a balanced weight distribution, so it will not be biased to one side when it is adjusted by universal sliding.

[0056] Specifically, the universal slide 231 is also provided with a fixed cylinder 236 inside, the fixed cylinder 236 is provided with a movable groove 237 inside, the movable groove 237 is movably provided with a movable pin 233 inside, one end of the movable pin 233 is provided with a movable piece 235, the movable groove 237 is provided with an adjusting spring 238, and the universal ball bearing 234 is embedded and movably provided at the other end of the movable pin 233.

[0057] Furthermore, the universal slide block 231 is also embedded with multiple fixed cylinders 236 arranged in a ring. The fixed cylinders 236 have movable grooves 237 inside. Movable pins 233 extending to the bottom of the fixed cylinders 236 are movably connected inside the movable grooves 237. Movable plates 235 that move within the movable grooves 237 are installed on the top of the movable pins 233. Adjusting springs 238 are installed inside the movable grooves 237. Universal ball bearings 234 are embedded and movably connected to the bottom of the movable pins 233.

[0058] Specifically, a positioning cylinder 232 is provided in the middle of the universal slide 231, and the sling 224 extends downward through the positioning cylinder 232. A cable hole 324 is provided in the middle of the movable platform 32, and the cable hole 324 corresponds to the positioning cylinder 232.

[0059] Furthermore, a hollow positioning cylinder 232 is embedded in the middle of the universal slide 231. Six hexagonal rollers are installed at the position where the inner ring of the positioning cylinder 232 contacts the sling 224 and can rotate through the shaft hole structure to prevent wear on the sling 224. The sling 224 extends downward through the positioning cylinder 232 to fix the lifting point. A cable hole 324 is provided in the middle of the movable platform 32, and the cable hole 324 is perpendicular to the positioning cylinder 232.

[0060] During hoisting operations, the hoisting frame 1 is moved above the material to be hoisted by the hoisting equipment. After the fixing device at the end of the sling 224 is fixed to the material, the servo motor 211 can be started to hoist the material. After the servo motor 211 is started, it drives the driven gear 214 to rotate through the power gear 212 and the transmission chain belt 213. The driven gear 214 drives the first bevel gear 215 to rotate. The first bevel gear 215 drives the second bevel gear 216, which meshes with it, to rotate and increase the rotational torque. The second bevel gear 216 drives the winch roller 222 to rotate and wind up the sling 224. When the sling 224 is wound up, the lifting point at the positioning cylinder 232 and the... The end of the sling 224 is not completely aligned with the fixed point of the material, and there is a certain offset. At this time, the sling 224 is in an inclined state, and the universal slide 231 contacts the movable platform 32 through the universal ball bearing 234. The friction is small. Therefore, when the sling 224 is initially wound up, the wound sling 224 will pull the universal slide 231 to slide towards the fixed point of the end of the sling 224 and the material, so that the lifting point at the positioning cylinder 232 is vertically aligned with the fixed point of the end of the sling 224 and the material. At this time, the sling 224 is in a vertical state. The sling 224 can be continuously wound up to lift the material vertically, and the material will not sway or shake due to the misalignment of the lifting point after being lifted up.

[0061] Example 2, refer to Figures 6 to 10 This is the second embodiment of the present invention, which differs from the previous embodiment in that it includes a self-locking mechanism 3.

[0062] Specifically, the activity platform 32 has an external universal slide groove 321, which is an annular groove, and the bottom surface of the universal slide groove 321 is a symmetrical inclined surface that tends towards the center.

[0063] Furthermore, the top of the activity platform 32 is provided with a universal slide groove 321, which is an annular groove. The bottom surface of the universal slide groove 321 is a symmetrical inclined surface that faces the center. When not being hoisted, the universal ball bearings 234 at the bottom of the universal slide block 231 are located in the central annular band. After hoisting, the universal slide block 231 can be automatically slid to the central state through the curved surface design.

[0064] Specifically, the fixed platform 31 has a fixing hole 314 on its outside, the movable platform 32 has a support pin 325 on its outside, the support pin 325 moves within the fixing hole 314, and a support spring 315 is provided within the fixing hole 314.

[0065] Furthermore, the top of the fixed platform 31 is provided with a plurality of fixed holes 314 arranged in a ring, and the fixed holes 314 are arranged in two rings, located on the outer ring and the inner ring of the fixed platform 31 respectively. The bottom of the movable platform 32 is provided with a plurality of support pins 325 corresponding to the fixed holes 314. The support pins 325 can extend and retract within the fixed holes 314. A support spring 315 located at the bottom of the support pin 325 is installed within the fixed holes 314.

[0066] It should be noted that in the non-lifting state, the weight of the universal slide 231 and the various mechanisms on its top, as well as the pressure when it is pulled and slid, are insufficient to fully compress the support spring 315. At this time, the movable platform 32 is in a slightly floating state, and the top of the first locking block 311 will not contact the bottom of the universal slide 231. Therefore, it does not affect the sliding alignment and centering reset of the universal slide 231 during lifting. Only when the material is lifted off the ground and its weight is added to the entire lifting mechanism 2 will the support spring 315 be fully compressed. At this time, the movable platform 32 moves downward, and the top of the first locking block 311 contacts the universal slide 231 to lock. After the goods are unloaded, the movable platform 32 rises again to unlock, realizing automatic locking and unlocking at different stages of lifting.

[0067] Specifically, a second locking block 312 is also provided on the outside of the fixed platform 31. Friction plates 313 are provided at the ends of the first locking block 311 and the second locking block 312. The movable platform 32 has a through first locking groove 322 and a through locking groove 323. The first locking block 311 and the second locking block 312 pass through the first locking groove 322 and the second locking groove 323 respectively.

[0068] Furthermore, multiple second locking blocks 312 are also installed on the outside of the fixed platform 31. The first locking block 311 and the second locking block 312 are arranged in a ring. The top of the first locking block 311 and the second locking block 312 are equipped with upward-facing friction plates 313. After the friction plates 313 on the top of the first locking block 311 and the second locking block 312 come into close contact with the bottom of the universal slide 231, the universal slide 231 is locked by the friction force of the evenly distributed friction plates 313. The movable platform 32 has a through first locking groove 322 and a second locking groove 323. The first locking block 311 and the second locking block 312 pass through the first locking groove 322 and the second locking groove 323 respectively and extend to the upper end of the movable platform 32.

[0069] After the universal slide 231 is initially wound and aligned by the winch roller 222, the winch roller 222 continues to wind the sling 224. At this time, the sling 224 lifts the material. When the material is lifted, the pressure on the movable platform 32 is not only the weight of the universal slide 231 and other components above the universal slide 231, but also the weight of the material itself. The weight of the material acts on the movable platform 32 through the sling 224, the winch roller 222, the lifting frame 221 and the universal slide 231. At this time, the movable platform 32 is pressed down, and the support pin 325 at the bottom of the movable platform 32 presses the spring down. At this time, the universal slide 231 moves down with the movable platform 32 and comes into contact with the friction plate 313 on the top of the first locking block 311 and the second locking block 312. At this time, the universal slide 231 is locked. As long as the material is lifted, the universal slide 231 is always locked and cannot slide.

[0070] After the hoisting is completed, the material is placed in the designated position and the sling 224 is separated from the material. Once the movable platform 32 loses the pressure exerted by the weight of the material, the support spring 315 pushes the support pin 325 upward. The support pin 325 drives the movable platform 32 to move upward, and the movable platform 32 drives the universal slide 231 to move upward. At this time, the friction plates 313 on the top surfaces of the first locking block 311 and the second locking block 312 at the bottom of the universal slide 231 separate from the bottom surface of the universal slide 231, and the universal slide 231 returns to a sliding state. At this time, the universal slide 231, through its own gravity and in conjunction with the specially shaped curved universal slide groove 321, naturally slides to the center position to complete the reset.

[0071] Example 3

[0072] Reference Figures 10 to 11 This is the third embodiment of the present invention, which differs from the above embodiments in that it includes hoisting equipment, including a hoisting frame 4;

[0073] The hoisting frame 4 is used to move the hoisting frame 1, so that the hoisting frame 1 and the hoisting mechanism 2 can move to the material location to lift the material and transfer the lifted material.

[0074] Furthermore, a hoisting mechanism 41 is installed on the top frame of the hoisting stand 4;

[0075] Furthermore, the hoisting frame 1 is movably connected to the hoisting upright 4.

[0076] Specifically, the hoisting mechanism 41 includes a movable beam 411 disposed inside the hoisting frame 4, a first motor 412 disposed outside the movable beam 411, a first transmission belt 413 disposed at the end of the first motor 412, a hoisting frame 1 disposed outside the movable beam 411, the first transmission belt 413 being connected to the hoisting frame 1, a second motor 414 disposed outside the hoisting frame 4, a second transmission belt 415 disposed at the end of the second motor 414, and the second transmission belt 415 being connected to the movable beam 411.

[0077] Furthermore, the hoisting mechanism 41 includes a movable beam 411 movably connected to the top frame of the hoisting stand 4 via a slide 11 and a guide rail. A first motor 412 is mounted on the outside of the movable beam 411. A first transmission belt 413 driven by two wheels is mounted at the end of the first motor 412, with one pulley fixedly connected to the output shaft of the first motor 412. The hoisting frame 1 is slidably connected to the guide rail via the slide 11 on the outside of the movable beam 411. The first transmission belt 413 passes through the hoisting frame 1 and is fixedly connected to the hoisting frame 1. A second motor 414 is provided on the outside of the hoisting stand 4. A second transmission belt 415 driven by two wheels is mounted at the end of the second motor 414, with one pulley fixedly connected to the output shaft of the second motor 414. The first transmission belt 413 passes through the movable beam 411 and is fixedly connected to the movable beam 411.

[0078] During material positioning before hoisting and material transfer during hoisting, the first motor 412 starts and drives the first transmission belt 413 to move. The hoisting frame 1 moves longitudinally on the movable beam 411 along with the first transmission belt 413, thereby driving the hoisting frame 1, the hoisting mechanism 2, and the locking mechanism to move longitudinally. At the same time, the second motor 414 drives the second transmission belt 415 to move. The movable beam 411 moves laterally on the movable beam 411 along with the second transmission belt 415, thereby driving the hoisting frame 1, the hoisting mechanism 2, and the locking mechanism to move laterally. The first motor 412 and the second motor 414 work together to enable the hoisting frame 1, the hoisting mechanism 2, and the locking mechanism to move and position freely within the range of the hoisting frame 4 to carry out the hoisting operation.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
