Detailed Implementation

[0020] The technical solutions in 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.

[0021] As attached Figure 1 Appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, an embodiment of the present invention provides a construction material feeding device, including a hook assembly 2 and a connecting assembly 3. The hook assembly 2 includes a pulley structure 21 and a hanging shaft 25. The pulley structure 21 is used to connect to the tower crane body 1 via a steel wire rope. The lower end of the pulley structure 21 is connected to a transverse hanging shaft 25. The connecting assembly 3 includes a bidirectional screw 332, a first motor 334, two hanging plates 31, and a horizontal pipe 33. The two horizontal pipes 33 are arranged in parallel and connected in the middle by an inner cylinder 331. The middle section of the bidirectional screw 332 is rotatably installed in the inner cylinder 331 via a bearing. The bidirectional screw 332 and the horizontal pipe 33 are connected in the middle by a steel wire rope. 3. The two hanging plates 31 are arranged in parallel and are respectively threaded to the bidirectional screws 332 located on both sides of the inner cylinder 331, and are slidably sleeved with the horizontal tube 33. The first motor 334 is installed at one end of the horizontal tube 33 and is used to connect and drive the bidirectional screws 332 to rotate. The bidirectional screws 332 are used to rotate and drive the hanging plates 31 on both sides to move towards or away from each other synchronously. The upper end of each of the two hanging plates 31 is provided with a hanging hole 311. The hanging hole 311 allows the two hanging plates 31 to be sleeved on the hanging shaft 25 from both ends when they are close to each other. The lower end of the inner cylinder 331 is connected to a bottom plate 35 for connecting materials.

[0022] This invention, through the arrangement of the hanging shaft 25 and the hanging plates 31, utilizes two adjustable-spaced hanging plates 31 to achieve connection or separation with the hanging shaft 25, thereby conveniently and reliably connecting the material tied to the base plate 35 to the hook assembly 2. This avoids problems such as unhooking, inconvenient hooking, or low connection strength that exist when connecting materials to the hook via steel cable hooks. Through the arrangement of the bidirectional screw 332, the first motor 334, and the horizontal tube 33, during use, the first motor 334 can control the bidirectional screw 332 to rotate forward and backward as needed, thereby driving the hanging plates 31 on both sides to move closer or further apart under the constraint of the horizontal tube 33. When the hanging plates 31 on both sides are close together, they can be sleeved on both ends of the hanging shaft 25 through the hanging holes 311 and move to clamp each other to conveniently complete the docking and assembly of materials. When the hanging plates 31 on both sides are far apart, the hanging plates 31 can be detached from the hanging shaft 25 for convenient disassembly of materials.

[0023] Specifically, the material is pre-tied and connected to the base plate 35 by cables, and then, with the cooperation of the connecting component 3, the tied material is easily connected to the hook component 2.

[0024] In this embodiment, end frames 333 are detachably provided at the ends of the two horizontal tubes 33. A first motor 334 is mounted on the end frames 333, and the power output shaft of the first motor 334 is connected to the end of the bidirectional screw 332. This arrangement allows for convenient assembly of the first motor 334, and the first motor 334 drives the bidirectional screw 332 to rotate, thereby adjusting the position of the hanging plate 31. Simultaneously, the end frames 333 can be fixed to the horizontal tubes 33 by bolts or other structures, thus increasing the reliability of the structure and preventing slippage of the hanging plate 31.

[0025] In this embodiment, the bottom of the aforementioned mounting plate 31 is provided with a guide hole 312 and a threaded hole 313. The guide hole 312 is used for sliding engagement with the horizontal tube 33, and the threaded hole 313 is used for threaded connection with the bidirectional screw 332. In this solution, the contact surface between the guide hole 312 and the horizontal tube 33 can be smoothed by applying lubricating oil or other methods to reduce the resistance to their relative movement.

[0026] As attached Figure 2 As shown, in a specific embodiment based on the above, the hook assembly 2 further includes a support plate 23. Vertical support plates 23 are installed on both sides of the bottom of the pulley structure 21, and a hanging shaft 25 horizontally connects the support plates 23 on both sides. In this embodiment, the two ends of the hanging shaft 25 horizontally penetrating the support plate 23 are used to respectively engage with the hanging holes 311 of the hanging plates 31 on both sides. During use, the hanging plates 31 on both sides can move closer together along the hanging shaft 25 until they are clamped to the sides of the support plates 23, thereby completing the positioning and limiting of the hanging plates 31 through the support plates 23, further ensuring the reliability of the assembly.

[0027] In further embodiments based on the above, hooks 24 are arranged on the hanging shaft 25 between the two side support plates 23. In this embodiment, the hooks 24 can be used to assist in hooking and binding the cable of the material, thereby increasing the docking means for the material and increasing the safety of hoisting.

[0028] In further embodiments based on the above, vertical waist-shaped holes are arranged on the support plates 23, and the hanging shafts 25 on both sides of the hooks 24 are vertically slidably arranged in the same side waist-shaped holes. In this embodiment, the hooks 24 can limit the lateral movement of the hanging shafts 25, and the vertical waist-shaped holes on the support plates 23 can increase the vertical adjustment range of the hanging shafts 25, thereby facilitating docking with the hanging hole 311.

[0029] In another embodiment based on the above, the hanging hole 311 is in a vertical waist shape. In this embodiment, the waist-shaped hanging hole 311 can facilitate docking with the hanging shaft 25, and after the two side hanging plates 31 are clamped, only vertical displacement is possible, so there is no risk of sliding during hoisting.

[0030] As shown in the accompanying drawings, Figure 7 In another embodiment based on the above, the bottom plate 35 is in a strip shape, and at least two downwardly open arc-shaped plates 36 are arranged on the bottom plate 35. In this embodiment, the cooperation of the two arc-shaped plates 36 can enable the bottom plate 35 to be stably placed on the material, facilitating binding with the material. Further, in this embodiment, the top of the arc-shaped plate 36 is provided with an embedded groove 361, the inside of the embedded groove 361 is provided with a clamping column, and a horizontal clamping groove 351 is formed on the bottom plate 35 corresponding to the clamping column. The arc-shaped plate 36 can be inserted into the clamping groove 351 through the clamping column in the embedded groove 361, and the installation with the bottom plate 35 is completed, and can be limited and fixed by a bolt structure.

[0031] As shown in the accompanying drawings, Figure 8 In further embodiments based on the above, a connecting mechanism 34 is arranged on the upper end of each side of the bottom plate 35, and the connecting mechanism 34 includes a main plate 341 and a turnover plate 343. The lower end of the main plate 341 is fixedly installed on the bottom plate 35, a front-to-rear groove 342 is arranged on the main plate 341, one side of the groove 342 is provided with an opening, and the turnover plate 343 is hingedly connected to one side of the main plate 341 at the opening of the groove 342. The turnover plate 343 is used to cover the opening of the groove 342, and the movable end of the turnover plate 343 is detachably connected to the main plate 341 by a bolt. In this embodiment, the cable for binding the material can pass through the groove 342 and be stably connected to the bottom plate 35, and after binding is completed, the turnover plate 343 is covered to limit the cable. In this scheme, the turnover plate 343 can be detachably connected to the main plate 341 by a bolt structure or a magnetic structure.

[0032] As attached Figure 6 As shown, in another specific embodiment based on the above, an internally threaded tube 335 is fixedly provided at the bottom of the inner cylinder 331. A driven gear 336 is fixedly sleeved on the outside of the internally threaded tube 335. A docking post 337 is internally threaded to the internally threaded tube 335. Two thrust bearings 338 distributed vertically are sleeved on the part of the docking post 337 extending out of the internally threaded tube 335. A connecting plate 371 sleeved on the outside of the docking post 337 is connected between the two thrust bearings 338. The connecting plate 371 is used to connect with the bottom plate 35. A second motor 381 is installed on the side of the connecting plate 371. A power gear 38 is installed on the output shaft of the second motor 381. The power gear 38 meshes with the driven gear 336. In this embodiment, starting the second motor 381 can drive the driven gear 336, along with the horizontal tube 33 and the entire hanging plate 31, to rotate relative to the bottom plate 35, thereby adjusting the orientation of the hanging plate 31 to facilitate docking between the hanging plate 31 and the hanging shaft 25. In this design, limiting bolts can also be added to the internally threaded tube 335 and the mating post 337 to ensure stable installation of the mating post 337 relative to the internally threaded tube 335. In this embodiment, the dimensions of the inner cylinder 331, the internally threaded tube 335, and the mating post 337 can be set as needed to meet the connection strength requirements.

[0033] In a further specific embodiment based on the above, two vertical plates 352 are installed at intervals along the middle section of the strip-shaped base plate 35. Each of the two vertical plates 352 has a snap-fit ​​groove 353 on its upper sidewall where they are close to each other. Both ends of the connecting plate 371 are provided with snap-fit ​​blocks 372, which are engaged with the snap-fit ​​grooves 353 of the two vertical plates 352 via the snap-fit ​​blocks 372 at the ends. This allows the connecting plate 371 to be detachably installed on top of the base plate 35, and the vertical plates 352 and snap-fit ​​blocks 372 can be connected by bolts to ensure a stable connection between the connecting plate 371 and the base plate 35.

[0034] In a further specific embodiment based on the above, a second positioning system 37 is installed on the other side of the connecting plate 371, and a first positioning system 22 is installed on the side of the hook assembly 2. The second positioning system 37 and the first positioning system 22 recognize and interact with each other. In this embodiment, the first positioning system 22 is installed on the side of the pulley structure 21 or the support plate 23. In the above scheme, an industrial camera 32 is also installed on the side of any horizontal tube 33. The industrial camera 32 is used to collect information and guide the horizontal tube 33 to rotate relative to the base plate 35, so that the hanging hole 311 is fitted onto the end of the hanging shaft 25.

[0035] In this embodiment, the first positioning system 22 includes at least UWB positioning tags, which broadcast location signals at a frequency of 1Hz. The second positioning system 37 is configured as a UWB base station, and other suitable UWB base stations are also placed in other locations. The tag coordinates are calculated using a TOF (Time-of-Flight) algorithm to generate material location information (X, Y, Z, where Z is the ground height, which can be preset). By using UWB, materials are given an identifiable identity. Vision and lasers are used to allow the tower crane to actively "see" the materials. Combined with 5G and edge computing, data flows in real time, and finally, the location information is linked with the BIM model to give it construction significance. This solution can improve the material positioning accuracy to ±10-30cm, shorten the positioning response time to within 1 second, significantly reduce the tower crane operator's "material search" time, and reduce the risk of collisions caused by position misjudgment. In addition, the first positioning system 22 and the second positioning system 37 also include a power system to provide power for the positioning system and other equipment. In general, by cooperating with the first positioning system 22 and the second positioning system 37, the tower crane body 1 can be guided to adjust the position of the hook assembly 2, so that the hook assembly 2 can be moved to the connecting assembly 3.

[0036] One specific embodiment of the present invention is as follows: Let's begin with a brief introduction to the structure of existing tower cranes. The tower crane structure can be divided into four main modules: metal structure (load-bearing main body), working mechanism (power execution), safety devices (protection and assurance), and electrical system (control center). Metal structure: The "skeleton" of the tower crane, bearing all the loads. The core components are made of high-strength steel, such as Q345 and Q460, and are welded or bolted together to ensure rigidity and fatigue resistance.

[0037] The foundation is the connection structure between the tower crane and the ground. It is necessary to evenly transfer the load of the tower crane to the ground to prevent overturning or settlement. Common types include: fixed concrete foundation, pile foundation, and mobile foundation.

[0038] The tower body is a vertical support structure that connects the foundation and the upper slewing mechanism. The height is adjusted by splicing "standard sections". The height of a single section ranges from 1.5m to 3m. The core types include rectangular / triangular cross-section tower bodies, circular cross-section tower bodies, and attachment devices.

[0039] The slewing bearing is the core component connecting the tower body and the upper rotatable structure. The upper structure is responsible for enabling luffing and hoisting operations, specifically including: Slewing bearing: It consists of an inner ring, an outer ring, and rolling elements (steel balls / rollers). The inner ring is fixed to the tower body, and the outer ring is connected to the slewing platform. It drives the upper structure to rotate 360° through a slewing drive device (motor + reducer) (slewing speed 0.5-1.5r / min), and bears radial, axial and overturning moments.

[0040] Slewing platform: Steel frame structure, upper part installs lifting mechanism, amplitude mechanism, cab, lower part connects with slewing bearing outer ring, is the "mounting platform" of upper part equipment.

[0041] Luffing boom: The "main arm" of tower crane, responsible for horizontal material transportation.

[0042] Counter jib: Symmetrically arranged with the luffing boom, the end of which is installed with "counterweight" (concrete block or steel block) to balance the weight of the luffing boom and load, preventing the tower crane from overturning (the weight of counterweight is designed according to the maximum rated load, usually 10t-50t), and the counter jib is also installed with lifting winch, cable drum and other equipment.

[0043] Tower top (tower cap): Located at the top of the slewing platform, connected with the luffing boom and counter jib through tie rods to transfer load, the tower top of horizontal luffing boom tower crane is a triangular truss (supporting luffing boom tie rod), and the tower top of luffing jib tower crane is a box structure (installing luffing jib amplitude pulley).

[0044] Working mechanism is the power execution system of tower crane, which realizes the four core actions of "lifting, slewing, amplitude, walking (part of tower crane)" through motor, reducer, steel wire rope, pulley, etc., all of which need to meet the requirements of "large torque, low speed, high reliability".

[0045] Lifting mechanism is the core working mechanism of tower crane, responsible for lifting materials from the ground to the sky, composed of lifting winch, steel wire rope, hook device, etc.

[0046] Amplitude mechanism is used to change the horizontal working radius of the hook, divided into two types: trolley amplitude mechanism and luffing jib amplitude mechanism.

[0047] Slewing mechanism drives the luffing boom and counter jib to rotate around the tower body, composed of slewing motor (usually 2-4, synchronous drive), slewing reducer (planetary gear or worm gear reducer), slewing pinion (meshing with the outer ring gear of slewing bearing), which can realize "clockwise / counterclockwise" rotation, and the rotation process is controlled by "slewing brake" (electromagnetic brake) to prevent inertia rotation.

[0048] Walking mechanism is used for track tower crane to move along the ground track, composed of walking motor (4, driving 4 walking wheels respectively), reducer, walking wheel (steel wheel, matching with the track), track clamp (automatically clamping the track when power off, preventing the tower crane from being blown by the wind), walking speed 3m-10m / min, limit block needs to be set at both ends of the track to prevent derailment.

[0049] Electrical system is responsible for controlling the action of each mechanism, transmitting signals and ensuring power supply, composed of the following parts: Power supply system: including the total distribution box (access to 380V three-phase alternating current, equipped with leakage protector), cable reel (for the cable when the tower height increases, avoid cable drag damage, emergency power supply (battery, power off for lighting, alarm use); Control system: using PLC (programmable logic controller) or frequency control system, to realize the "start-stop, speed regulation, linkage" of each mechanism (such as synchronous action of lifting and rotating), part of the intelligent tower crane is equipped with touch screen, which can display the operating parameters (load, height, amplitude); Operating system: including the operation panel (handle, button, indicator light) and wireless remote control (part of the tower crane is equipped, which is convenient for ground personnel to assist operation), the operation handle outputs signal through potentiometer or encoder, which controls the motor speed; Signal system: including warning light (tower top red flashing light, night reminder), horn (for warning ground personnel during operation), camera (part of the tower crane is equipped, the driving cab display screen can view the field below the hook, avoid blind area).

[0050] The above-mentioned tower crane structure is divided into two categories, one is the tower crane body 1 and the hook device, that is, the part except the hook device is called the tower crane body 1, and the embodiment mainly describes the improved hook device.

[0051] As shown in the accompanying drawings, Figure 9 Specifically, the hook assembly 2 is suspended below the tower crane body 1, and the first positioning system 22 and the second positioning system 37 guide the hook assembly 2 to move above the connecting assembly 3; then, under the guidance of the industrial camera 32, the second motor 381 is started to drive the driven gear 336, the horizontal pipe 33 and the hanging plate 31 on it as a whole to rotate relative to the bottom plate 35, so as to adjust the orientation of the hanging plate 31, until the hanging plate 31 can be connected with the hanging shaft 25; then the first motor 334 is driven to control the bidirectional screw rod 332 to rotate forward, so that the two hanging plates 31 move close to each other under the constraint of the horizontal pipe 33, and after the hanging hole 311 is sleeved on both ends of the hanging shaft 25 and moves to be clamped to each other, the material is connected and assembled; then, the tower crane body 1 works to realize the feeding of the material.

[0052] When it is needed to unload, the first motor 334 is driven in reverse, so that the two hanging plates 31 move away from each other, and then the hanging plate 31 can be separated from the hanging shaft 25, so as to conveniently disassemble the material.

[0053] It should be noted that the terms such as "upper", "lower", "left", "right", "front", "rear" and the like referred to in the invention are only for the convenience of clear description, and are not used to limit the scope of the invention, and the change or adjustment of the relative relationship is also considered as the scope of the invention without substantial change of the technical content.
