Abstract

This invention provides an integrated hoisting and positioning device for heavy equipment, relating to the field of hoisting technology. It includes a housing with symmetrically arranged lifting lugs at the upper end. A multi-functional structure is mounted on the housing, comprising an electronic control processing unit located above the housing. Gyro stabilizers are distributed at the four corners of the housing. The electronic control processing unit collects and fuses the three-dimensional attitude data of the four gyro stabilizers in real time.

It also eliminates the ineffective work time spent by operators waiting for sway decay, significantly improving hoisting efficiency.

Description

Technical Field

[0001] This invention belongs to the field of hoisting technology, and more specifically, relates to an integrated hoisting and positioning device for heavy equipment. Background Technology

[0002] The hoisting of heavy equipment is a core operational step in the installation of large industrial equipment, engineering construction, and equipment manufacturing. Specialized hoisting tools are key equipment to ensure the safety, accuracy, and efficiency of hoisting operations.

[0003] A search of Chinese patent publication number "CN116119519B" reveals "a hook device". This hook device can open the hook by setting a counterweight block and cooperating with the hook body to achieve automatic unloading of items, while also ensuring safety. It has a simple structure and is convenient and practical.

[0004] Based on the above search and existing technology findings, the aforementioned patent has certain defects: the device only optimizes the automatic unloading structure of the hook, focusing on achieving automatic unloading of the hoisted items, and does not set up supporting structures for hoisting posture stability suppression, stepless adjustment of hook spacing, and active control of hook angle. In actual hoisting operations, the lifting device is easily affected by wind resistance disturbance and lifting braking inertia, resulting in swaying. This poses a safety risk of the workpiece colliding with surrounding structures and also increases the ineffective waiting time for sway attenuation. At the same time, the fixed lifting distance hook cannot be adapted to heavy workpieces of different specifications and different lifting point spans, requiring frequent replacement of special lifting devices, which is inconvenient to use. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an integrated device for hoisting and positioning heavy equipment.

[0006] A heavy equipment hoisting and positioning integrated device includes a housing, and the upper end of the housing is symmetrically provided with lifting lugs.

[0007] Preferably, the housing is provided with a multi-functional structure, the multi-functional structure including an electronic control processing unit, the electronic control processing unit is located on the top of the housing, the electronic control processing unit is located inside the lifting lug, and gyro stabilizers are provided at the four corners of the housing. The electronic control processing unit can control the gyro stabilizers to start. A sliding groove is provided inside the housing, and a bidirectional lead screw is rotatably installed inside the sliding groove through a bearing.

[0008] Preferably, a set of limiting posts is fixedly installed inside the housing. The set of limiting posts is located outside the bidirectional lead screw and is arranged in a circumferential pattern with the center of the bidirectional lead screw as the center point. A first servo motor is fixedly installed on the side wall of the housing. The output shaft of the first servo motor is fixedly connected to one end of the bidirectional lead screw through a coupling. Slider blocks are symmetrically fixedly installed inside the slide groove. The sliders are threadedly installed on the bidirectional lead screw.

[0009] Preferably, the slider and the limiting post assembly are slidably installed, the bottom of the slider is provided with a rotating groove, a first rotating shaft is rotatably installed inside the rotating groove via a bearing, a hook is rotatably installed inside the first rotating shaft, a sliding sleeve is threaded on the side of the hook away from the hook end, and a slide bar is slidably installed between the two sliding sleeves.

[0010] Preferably, symmetrical support columns are fixedly installed on the side wall of the slide bar, and side brackets are fixedly installed symmetrically at the lower end of the housing. A second rotating shaft is rotatably installed on the inner side of the side bracket via a bearing. The center of the second rotating shaft is parallel to the center of the first rotating shaft. A second servo motor is fixedly installed on one side surface of the housing. The output shaft of the second servo motor is fixedly connected to the second rotating shaft via a coupling. A connecting rod is fixedly installed between the second rotating shaft and the support column.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, gyro stabilizers are distributed at the four corners of the shell. The electronic control processing unit collects and merges the three-dimensional attitude data of the four gyro stabilizers in real time. When the device is detected to be swaying or tilting in any direction due to wind resistance disturbance or lifting braking inertia, the corresponding gyro stabilizer is immediately activated to generate a reverse compensation torque. This can actively suppress the hoisting sway from the source throughout the hoisting process, maintain the overall horizontal stability of the device, avoid the positioning difficulties and safety risks of collision with surrounding structures caused by workpiece swaying during hoisting, and eliminate the ineffective work time of operators waiting for the sway to decay, thus greatly improving the efficiency of hoisting operations.

[0013] In this invention, a first servo motor drives a bidirectional lead screw to rotate, causing two sliders to slide synchronously in opposite directions or away from each other within a groove along a set of circumferentially arranged limiting posts. The sliders drive the hooks to move synchronously via a first rotating shaft, thereby enabling stepless and precise adjustment of the distance between the two hooks. This adapts to heavy workpieces of different specifications and lifting point spans, solving the pain points of traditional fixed-distance lifting tools that cannot be compatible with multiple types of equipment and require frequent replacement of special lifting tools. At the same time, the limiting post set provides multi-guide support to prevent the sliders from deflecting and getting stuck. The helical drive of the bidirectional lead screw has a self-locking characteristic, automatically maintaining a stable distance after adjustment without the need for an additional locking mechanism, ensuring a safe and reliable lifting process.

[0014] In this invention, a sliding sleeve is threaded onto the side of the hook furthest from the hook end, and a sliding strip is slidably installed between the two sliding sleeves. This allows two independent hooks to be connected into a unified load-bearing structure with the assistance of the sliding strip. When hoisting heavy equipment, the two hooks form a coordinated load-bearing system, avoiding torsional deformation caused by uneven force on a single hook. At the same time, when the lateral spacing of the hooks is adjusted, the sliding sleeve can adaptively slide along the surface of the sliding strip, ensuring the freedom of spacing adjustment and providing mutual auxiliary limiting and lateral support for the two hooks. This prevents the hooks from lateral swaying or twisting during hoisting, ensuring that the two hooks always maintain a parallel and synchronous working state, effectively improving the force balance and structural stability of double-hook hoisting.

[0015] In this invention, the receiving columns are symmetrically fixed to the side wall of the slide bar, and a second rotating shaft is installed on the side bracket at the lower end of the housing. A connecting rod is fixed between the second rotating shaft and the receiving column. A second servo motor drives the second rotating shaft to rotate, thereby causing the connecting rod to swing in a circle around the center of the second rotating shaft. The connecting rod drives the slide bar to make a synchronous arc movement through the receiving column. The slide bar drives the two hooks to swing back and forth around the first rotating shaft at a controllable angle through the sliding sleeve, so that the hook ends can actively raise outward or retract inward, greatly improving the convenience and safety of the hooking operation.

[0023] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0024] Please see Figure 1 - Figure 6 This invention provides an integrated hoisting and positioning device for heavy equipment, including a housing 11. The upper end of the housing 11 is symmetrically provided with lifting lugs 12. The housing 11 is provided with a multi-functional structure, which includes an electronic control processing unit 13. The electronic control processing unit 13 is located above the housing 11 and inside the lifting lugs 12. Gyro stabilizers 14 are provided at the four corners of the housing 11. The electronic control processing unit 13 can control the gyro stabilizers 14 to start.

[0025] The housing 11 is a rectangular box structure, welded from Q355B high-quality carbon structural steel plate with a thickness of not less than 12mm. After sandblasting and rust removal, it is coated with anti-corrosion paint. The lifting lugs 12 are two symmetrically arranged thick steel plates, integrally cut from Q355B steel plate with a thickness of not less than 30mm. They have lifting holes and are fully welded to the top surface of the housing 11 at the bottom for connecting to an external crane. The electrical control processing unit 13 is an industrial-grade waterproof control box with an aluminum alloy die-cast shell. It contains a PLC control module and signal processing circuit, power supply module and circuit, charging interface, etc., for collecting attitude signals and outputting control commands. The gyroscope stabilizer 14 is an industrial-grade MEMS gyroscope stabilization module with an aluminum alloy package. Four sets are fixed to the four corners of the housing 11 with bolts and connected to the electrical control processing unit 13 through shielded cables. It is controlled by the electrical control processing unit 13 to generate a reverse torque to suppress the swaying of the lifting.

[0026] By distributing gyro stabilizers 14 at the four corners of the housing 11, the electronic control processing unit 13 collects and fuses the three-dimensional attitude data of the four gyro stabilizers 14 in real time. When the device is detected to be swaying or tilting in any direction due to wind resistance disturbance or lifting braking inertia, the corresponding gyro stabilizer 14 is immediately controlled to start generating a reverse compensation torque. This can actively suppress the hoisting sway from the source throughout the hoisting process, maintain the overall horizontal stability of the device, avoid the positioning difficulties and safety risks of collision with surrounding structures caused by workpiece sway during hoisting, and eliminate the ineffective work time of the operator waiting for the sway to decay, thus greatly improving the efficiency of hoisting operations.

[0027] The housing 11 has a sliding groove 15 inside, and a bidirectional lead screw 16 is rotatably mounted inside the sliding groove 15 via bearings. A limit post assembly 17 is fixedly installed inside the housing 11. The limit post assembly 17 is located outside the bidirectional lead screw 16 and is arranged in a circumferential pattern with the center of the bidirectional lead screw 16 as the center point. A first servo motor 18 is fixedly installed on the side wall of the housing 11. The output shaft of the first servo motor 18 is fixedly connected to one end of the bidirectional lead screw 16 via a coupling. Slider 19 is symmetrically fixedly installed inside the sliding groove 15. The slider 19 is threadedly installed on the bidirectional lead screw 16.

[0028] The slide groove 15 is a rectangular through groove machined inside the housing 11. The bidirectional lead screw 16 is integrally machined from 40Cr alloy steel, with trapezoidal threads of opposite directions machined on the left and right ends. Both ends are rotatably mounted on the inner walls of the slide groove 15 via deep groove ball bearings, used to drive the sliders 19 to move synchronously in opposite directions. The limit post group 17 consists of four chrome-plated optical shafts, made of 45# steel with a hard chrome plating, distributed in a rectangle around the center of the bidirectional lead screw 16. The first servo motor 18 is a high-torque industrial servo motor. The motor is fixedly installed on the outer wall of the housing 11 by flange bolts. The output shaft is coaxially fixedly connected to one end of the double-acting screw 16 through a flexible coupling to provide driving power for the rotation of the screw. There are two symmetrically arranged sliders 19, which are made of HT250 gray cast iron. The internal threads are machined to match the double-acting screw 16 and four limit post sliding holes. They are installed on the double-acting screw 16 by thread and simultaneously slide with the limit post group 17 to drive the hook 23 to achieve lateral spacing adjustment.

[0029] The first servo motor 18 drives the bidirectional lead screw 16 to rotate, causing the two sliders 19 to slide synchronously in opposite directions or away from each other within the slide groove 15 along the surrounding circumferentially arranged limit column group 17. The sliders 19 drive the hooks 23 to move synchronously through the first rotating shaft 22, thereby achieving stepless and precise adjustment of the distance between the two hooks 23. This adapts to heavy workpieces of different specifications and different lifting point spans, solving the pain points of traditional fixed lifting distance lifting tools that cannot be compatible with the lifting of multiple models of equipment and require frequent replacement of special lifting tools. At the same time, the limit column group 17 provides multi-guide support to prevent the sliders 19 from deflecting and getting stuck. The helical drive of the bidirectional lead screw 16 has a self-locking characteristic, and automatically maintains a stable distance after adjustment without the need for an additional locking mechanism, ensuring a safe and reliable lifting process.

[0030] The slider 19 is slidably installed with the limit post assembly 17. The bottom of the slider 19 has a rotating groove 21. The first rotating shaft 22 is rotatably installed inside the rotating groove 21 through a bearing. The hook 23 is rotatably installed inside the first rotating shaft 22. The side surface of the hook 23 away from the hook end is threaded with a sliding sleeve 24. A slide bar 25 is slidably installed between the two sliding sleeves 24.

[0031] Bearing mounting holes are machined on both sides of the rotating groove 21. The first rotating shaft 22 is made of 40Cr alloy steel and is rotatably installed in the bearing holes of the rotating groove 21 at both ends through deep groove ball bearings. It is used to provide a swing rotation fulcrum for the hook 23. The hook 23 is made of alloy steel and is integrally forged and heat-treated. The hook part is quenched and the rod part passes through the center hole of the first rotating shaft 22 to achieve a rotatable connection. It is used to hang and lift heavy equipment. The slide bar 25 is made of 45 steel and is machined into a long rectangular section. The surface is treated with high frequency quenching to improve wear resistance. The two ends are respectively inserted into the center sliding holes of the two sliding sleeves 24 to form a sliding fit. It is used to synchronously drive the two hooks 23 to swing.

[0032] A sliding sleeve 24 is threaded onto the side of the hook 23 furthest from the hook end, and a sliding strip 25 is slidably installed between the two sliding sleeves 24. This allows the two independent hooks 23 to be connected into an integral load-bearing structure through the sliding strip 25. When lifting heavy equipment, the two hooks 23 form a coordinated load-bearing system, avoiding torsional deformation caused by uneven force on a single hook. At the same time, when the lateral spacing of the hooks 23 is adjusted, the sliding sleeve 24 can adaptively slide along the surface of the sliding strip 25, ensuring the freedom of spacing adjustment and providing mutual auxiliary limiting and lateral support for the two hooks 23. This prevents the hooks 23 from lateral swaying or twisting during lifting, ensuring that the two hooks 23 always maintain a parallel and synchronous working state, effectively improving the force balance and structural stability of double-hook lifting.

[0033] A receiving column 31 is symmetrically fixedly installed on the side wall of the slide bar 25. A side bracket 26 is symmetrically fixedly installed on the lower end of the housing 11. A second rotating shaft 27 is rotatably installed on the inner side of the side bracket 26 through a bearing. The center of the second rotating shaft 27 is parallel to the center of the first rotating shaft 22. A second servo motor 28 is fixedly installed on one side surface of the housing 11. The output shaft of the second servo motor 28 is fixedly connected to the second rotating shaft 27 through a coupling. A connecting rod 29 is fixedly installed between the second rotating shaft 27 and the receiving column 31.

[0034] The receiving column 31 is made of 45# steel and is formed into a cylindrical pin structure. Two pieces are symmetrically welded and fixed to the two side walls of the slide bar 25. It is used to connect the connecting rod 29 to transmit the swing power. The side bracket 26 is made of Q235B steel plate and is formed into an L-shaped bracket. Two pieces are symmetrically welded and fixed to the two sides of the lower end face of the housing 11. It is used to support and install the swing drive shaft. The second shaft 27 is made of 40Cr alloy steel and is rotatably installed in the shaft holes of the two side brackets 26 through deep groove ball bearings at both ends. Its axis is spatially parallel to the axis of the first shaft 22. It is used to output the swing rotation power. The second servo motor 28 is a high torque industrial servo motor. It is fixedly installed on the outer surface of one side of the housing 11 through flange bolts. The output shaft is coaxially fixed to one end of the second shaft 27 through a flexible coupling. It is used to provide the driving power for the swing of the hook 23. The connecting rod 29 is made of 45# steel and is formed into a long rod shape. The shaft holes are machined at both ends. One end is connected and fixed to the second shaft 27, and the other end is fixed to the receiving column 31.

[0035] The receiving column 31 is symmetrically fixed to the side wall of the slide bar 25. The second rotating shaft 27 is installed on the side bracket 26 at the lower end of the housing 11. The connecting rod 29 is fixed between the second rotating shaft 27 and the receiving column 31. The second servo motor 28 drives the second rotating shaft 27 to rotate, thereby driving the connecting rod 29 to swing in a circle around the center of the second rotating shaft 27. The connecting rod 29 drives the slide bar 25 to make synchronous arc motion through the receiving column 31. The slide bar 25 drives the two hooks 23 to swing back and forth around the first rotating shaft 22 at a controllable angle through the sliding sleeve 24, so that the hook end of the hook 23 can actively raise outward or retract inward, greatly improving the convenience and safety of the hanging operation.

[0036] Working principle:

[0037] During lifting operations, an external crane lifts the entire device via the lifting lugs 12 at the top of the housing 11. Heavy equipment is then hooked and secured using two hooks 23. During the lifting process, the electronic control processing unit 13 receives attitude data in real time from the gyro stabilizers 14 at the four corners. When the device sways or tilts due to wind resistance or braking, the electronic control processing unit 13 controls the gyro stabilizers 14 to generate a reverse torque, suppressing the swaying at its source and maintaining the overall horizontal stability of the device. When it is necessary to adjust the hook spacing laterally to accommodate equipment with different lifting distances, the first servo motor 18 drives the bidirectional lead screw 16 to rotate. The bidirectional lead screw 16 drives two sliders 19 to slide in opposite directions or away from each other along the limit post group 17 within the slide groove 15. The sliders 19 drive the hooks 23 to move synchronously via the first rotating shaft 22. The stepless adjustment of the distance between the two hooks 23 adapts to the span of lifting points for workpieces of different specifications. When auxiliary hooking operations are required, the second servo motor 28 drives the second rotating shaft 27 to rotate. The second rotating shaft 27 drives the connecting rod 29 to swing around the center of the second rotating shaft 27. The connecting rod 29 drives the slide bar 25 to make synchronous arc movements through the bearing column 31. The slide bar 25 drives the two sliding sleeves 24 to move synchronously. The sliding sleeves 24 drive the hook 23 to swing around the first rotating shaft 22, so that the hook end of the hook 23 actively raises outward or moves inward, which facilitates the operator to quickly complete the workpiece or material hooking operation. The lateral adjustment of the distance and the swinging function of the hook 23 can be carried out independently or in conjunction. With the attitude stabilization function of the gyro stabilizer 14, the safety and positioning accuracy of the lifting operation can be improved.
