Description

Technical Field

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

[0002] Construction hoisting equipment is the core heavy machinery for vertical and horizontal transportation of components in engineering construction. Its core function is to accurately lift and place materials such as steel bars, formwork, precast components, and large equipment, covering the entire construction stage from foundation construction to main structure capping.

[0003] In traditional construction hoisting operations, there is a lack of a dynamic, real-time monitoring mechanism for the connection and fixation of hoisting ropes and lifting equipment. Once the ropes become loose or displaced due to equipment vibration, load fluctuations, or component wear, on-site personnel often cannot detect the abnormality in the first place. The problem is only discovered when the building materials show obvious shaking or even fall. Summary of the Invention

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The hoisting equipment disclosed in this invention is mainly used in scenarios where the rope fixation status lacks real-time monitoring and there is no early warning of loosening in traditional hoisting operations, resulting in safety accidents that cannot be prevented in advance.

[0028] Reference Figures 1-8 A hoisting device for building construction includes a crane platform 1. A hoisting arm 8 is provided at the top of the crane platform 1. An extension rod 9 is provided at the front end of the hoisting arm 8. A movable arm 10 is provided at the front end of the extension rod 9. A telescopic device 12 is provided at the front end of the movable arm 10. A hanging plate 15 is provided below the telescopic device 12. A hoisting rope 16 is provided on the hanging plate 15. Two rope fixation detection components 14 are provided on the outer side of the hoisting rope 16. The rope fixation detection component 14 includes a fixing member 1401. The bottom end of the fixing member 1401 is fixedly connected to the top end of the hanging plate 15. A fixing circle 1412 is provided above the fixing member 1401. The inner side of the fixing circle 1412 is fixedly connected to the outer side of the hoisting rope 16. Two locking grooves are provided on the fixing circle 1412. Each locking groove is provided with a locking member 1411.

[0029] Reference Figures 3-6In a preferred embodiment, two sliding grooves 1407 are fixedly connected to the outer side of the retaining member 1401, a sliding ring 1403 is slidably connected to the outer side of the sliding groove 1407, and the inner side of the sliding ring 1403 is slidably connected to the outer side of the retaining member 1401. A telescopic electric rod 1402 is fixedly connected to the top of the hanging plate 15, and the telescopic end of the telescopic electric rod 1402 is fixedly connected to the bottom end of the sliding ring 1403.

[0030] In this invention, a telescopic rod 1406 is fixedly connected to the top of the hanging plate 15, and a dislocation detection device 1404 is fixedly connected to the top of the telescopic rod 1406. The top of the dislocation detection device 1404 is in contact with the bottom of the sliding ring 1403. A tension spring 1405 is fixedly connected to the bottom of the sliding ring 1403, and the tension spring 1405 is located outside the telescopic rod 1406. The bottom of the tension spring 1405 is fixedly connected to the top of the hanging plate 15. Two connecting frames 1408 are fixedly connected to the top of the sliding ring 1403, and a drive motor 1409 is provided on one side of each connecting frame 1408.

[0031] In this invention, the power output shafts of the two drive motors 1409 are connected to rotating rods 1410 via couplings. The outer ends of both ends of the rotating rods 1410 are movably connected to the inner side of the connecting frame 1408. The outer ends of the rotating rods 1410 are movably connected to the inner side of the bottom end of the locking member 1411. The locking grooves on the retaining round member 1412 are fixedly connected to pressing springs 1413. The top ends of the pressing springs 1413 are fixedly connected to pressing plates 1414. The pressing plates 1414 are all located inside the locking member 1411.

[0032] Specifically, to ensure a safe and reliable connection between the lifting rope 16 and the lifting plate 15, firstly, the two drive motors 1409 on the lifting plate 15 receive a start signal. One drive motor 1409 rotates in the forward direction, and the other rotates in the reverse direction. The power output shaft of the drive motor 1409 drives the rotating rod 1410 to rotate through a coupling. The two ends of the rotating rod 1410 are movably connected to the inner side of the connecting frame 1408. The rotational motion is converted into the horizontal movement of the locking member 1411. Driven by the rotating rod 1410, the two locking members 1411 approach each other, precisely aligning with the locking groove on the fixed retaining member 1412, which is fixedly connected to the lifting rope 16, and gradually being placed into the groove. Subsequently, the telescopic electric rod 1402 is started, and the telescopic end pushes the sliding ring 1403 to move downward along the outer side of the fixed retaining member 1401 and the sliding groove member 1407. The downward movement of the sliding ring 1403 synchronously drives the tension spring 1405. The ring is compressed to store elastic potential energy for subsequent repositioning. Simultaneously, the bottom end of the sliding ring 1403 remains in continuous contact with the top end of the dislocation detection device 1404. The dislocation detection device 1404 is kept vertical by the guide of the telescopic rod 1406, monitoring the positional changes of the sliding ring 1403 in real time. An alarm is triggered if abnormal dislocation occurs. As the sliding ring 1403 continues to move downwards, the connecting frame 1408 drives the locking member 1411 to further engage within the locking groove. The bottom end of the locking member 1411 contacts the pressing plate 1414 within the locking groove, continuously pressing the pressing spring 1413. The elastic reaction force of the pressing spring 1413 makes the contact between the locking member 1411 and the locking groove even tighter, thus firmly fixing the end of the lifting rope 16 to the lifting plate 15. At this time, the two lifting ropes 16 are symmetrically positioned below the building material, ensuring uniform force during lifting.

[0033] After the positioning is completed, the dislocation detection device 1404 will continuously monitor the position of the sliding ring 1403. If abnormal situations such as the sliding ring 1403 moving upward or the locking part 1411 becoming loose occur during the hoisting process, the dislocation detection device 1404 will immediately send a signal to the control system to trigger the emergency braking procedure to prevent the building materials from falling.

[0034] The dislocation detection device 1404 is a pressure sensor with a detection range of 0-500N and a detection accuracy of ±1N. Its detection end is in continuous close contact with the bottom end of the sliding ring 1403, which can collect the analog pressure signal applied by the sliding ring in real time and transmit the signal stably to the central control system integrated inside the crane platform 1.

[0035] Detailed supplement to control logic

[0036] Signal type: The dislocation detection device (pressure sensor) transmits an analog pressure signal to the central control system. The system presets the normal operating pressure threshold for rope fixation to be 100-200N. When the detected pressure value is <100N, it is determined to be an abnormal fixation and triggers the emergency braking procedure.

[0037] Control system actions: The central control system is electrically connected to the dislocation detection device, telescopic electric mast, drive motor, lifting arm, extension rod, moving arm, telescopic device control terminals, and equipment audible and visual alarm devices. Upon receiving an abnormal analog signal, it synchronously performs the following operations: sends a power-off signal to the drive motor control terminals of lifting arm 8, extension rod 9, moving arm 10, and telescopic device 12 to cut off the power supply to all lifting and transfer mechanisms, causing them to immediately stop all actions; sends a locking signal to telescopic electric mast 1402 and drive motor 1409 to lock the telescopic end of the telescopic electric mast to the output shaft of the drive motor, preventing the locking piece 1411 from further loosening; and triggers the equipment audible and visual alarm devices, emitting a red light and a continuous buzzer alarm signal to alert on-site operators of abnormal rope fixation.

[0038] It should be noted that the position change of the sliding ring 1403 can be monitored in real time, thereby indirectly monitoring the fixation status of the locking component 1411. The dislocation detection device 1404 can capture the abnormal position signal at the first time and quickly feed it back to the equipment control system, triggering the emergency braking procedure in time, so that the hoisting equipment stops immediately, effectively preventing safety accidents such as falling building materials and equipment damage caused by rope dislocation, and eliminating safety hazards in hoisting operations in the bud.

[0039] In actual use, the locking component 1411 is precisely embedded into the locking groove of the fixing round component 1412 under the drive of the drive motor 1409, completing the basic mechanical locking. The pressing spring 1413 in the locking groove forms a continuous elastic pressure on the locking component 1411 through the pressing plate 1414, which offsets the lateral and longitudinal impact forces generated by equipment shaking and material swinging during the hoisting operation, preventing the locking component 1411 from being loosened by vibration, and at the same time firmly locking the end of the hoisting rope 16 in the fixing structure.

[0040] Additional details on the interaction between the locking component and the pressing plate (pressing spring parameters): The initial pre-compression of the pressing spring 1413 is 5-10mm, and the natural elastic force ranges from 80-150N. After the bottom end of the locking component 1411 contacts the pressing plate 1414 and forms a continuous pressing, the compression of the pressing spring increases by 2-5mm based on the initial pre-compression, and the elastic force is correspondingly increased to 120-200N. Through the elastic reaction force, the locking component and the locking groove are tightly fitted, offsetting the lateral and longitudinal impact forces generated by equipment vibration and material swaying during hoisting operations.

[0041] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, bottom support components 11 are provided on both sides of the crane platform 1. The bottom support components 11 include a circular platform 1101. A rectangular hole is opened inside the circular platform 1101, and a motor frame 1104 is fixedly connected to the top of the rectangular hole. A bidirectional motor 1105 is fixedly connected inside the motor frame 1104.

[0042] In this invention, the power output shafts at both ends of the bidirectional motor 1105 are connected to threaded rods 1106 via couplings. The opposite ends of the threaded rods 1106 are movably connected to both sides of a rectangular hole. Two guide rods 1107 are fixedly connected to the inner side of the rectangular hole, and two moving parts 1108 are slidably connected to the outer sides of the threaded rods 1106 and the guide rods 1107.

[0043] In this invention, positioning rods 1109 are fixedly connected to both sides of the movable component 1108, lifting rods 1110 are movably connected to the outer sides of the positioning rods 1109, connecting rods 1111 are movably connected to the inner side of the bottom end of the lifting rods 1110 away from the positioning rods 1109, pressing bases 1103 are fixedly connected to both ends of the connecting rods 1111, sliding plates 1102 are fixedly connected to both sides of the rectangular hole, and the pressing bases 1103 are slidably connected to the opposite side of the sliding plates 1102 on both sides.

[0044] Specifically, after the support arm 4 expands into place, the bidirectional motor 1105, fixed in the rectangular hole inside the circular platform 1101 by the motor frame 1104, starts. The power output shafts at both ends drive the threaded rod 1106 to rotate synchronously. The rotation of the threaded rod 1106 drives the outer moving part 1108 to slide along the guide rod 1107 towards each other. The positioning rods 1109 on both sides of the moving part 1108 move synchronously, causing the lifting rod 1110, which is movably connected to it, to rotate downwards. The end of the lifting rod 1110 away from the positioning rod 1109 is movably connected to the connecting rod 1111. When the lifting rod 1110 presses down, the connecting rod 1111 drives the pressing base 1103 to move vertically downward along the sliding plates 1102 on both sides of the rectangular hole. The pressing base 1103 continues to move down until it is in complete contact with the ground. Under the continuous drive of the bidirectional motor 1105, a pre-pressure is generated, thereby evenly transferring the weight of the crane platform 1 to the ground and effectively dispersing the vertical load and horizontal torque generated during the hoisting operation. At this time, the center of gravity of the entire equipment is lowered to the ground through the bottom support component 11, forming a stable support structure and providing a solid foundation for subsequent high-altitude hoisting operations.

[0045] It should be noted that, with the circular platform 1101 as the basic carrier, the two pressing base platforms 1103 are driven by the bidirectional motor 1105 to simultaneously contact the ground downwards, forming a symmetrical double-support structure. Combined with the support points of the original tires 3 of the crane platform 1, the entire equipment forms a stable multi-support system.

[0046] In practical applications, the synchronous drive of the bidirectional motor 1105 ensures that the movements of the moving parts 1108 and the lifting rod 1110 on both sides are completely consistent, ensuring that the two pressing bases 1103 move down and bear pressure synchronously, avoiding the crane platform 1 from being tilted due to one side being in place or one side lagging behind. At the same time, the helical drive of the threaded rod 1106 has the characteristics of controllable stroke and precise positioning, which can accurately adjust the downward distance and bearing pressure of the pressing base 1103 according to the ground conditions on site, so that the support effect is highly matched with the on-site working conditions, improving the accuracy and efficiency of the support operation.

[0047] Reference Figures 1-4 In a preferred embodiment, a guardrail 5 is fixedly connected to the top of the crane platform 1, a rear box 2 is fixedly connected to the side of the crane platform 1 near the guardrail 5, and tires 3 are provided at both ends of the rear box 2. Two rotating parts 6 are fixedly connected to the side of the crane platform 1 away from the rear box 2. A rotating shaft 7 is fixedly connected to the inner side of each rotating part 6, and a support arm 4 is movably connected to the outer side of each rotating shaft 7. The bottom end of each support arm 4 is fixedly connected to the top of the circular platform 1101. A hook 13 is provided at the bottom end of the telescopic device 12, and the lifting rope 16 is placed above the hook 13.

[0048] Working principle: Before the hoisting operation starts, the equipment first moves the site by means of the tires 3 on both sides of the rear box 2. The operator drives the tires 3 to rotate through the control system, so that the crane platform 1 can be driven to the designated hoisting position smoothly. The side of the crane platform 1 away from the rear box 2 is equipped with a rotating part 6. The rotating shaft 7 fixed inside starts to rotate, which drives the support arm 4 connected to it to expand outward to both sides of the crane platform 1. The outward expansion angle of the support arm 4 can be precisely adjusted according to the flatness of the ground and the hoisting weight until the preset stable angle is reached. As the support arm 4 extends outward, the circular platform 1101 moves synchronously to the designated position on both sides of the crane platform 1.

[0049] When the support arm 4 is fully extended, the bidirectional motor 1105, fixed in the rectangular hole inside the circular platform 1101 by the motor frame 1104, starts. The power output shafts at both ends drive the threaded rod 1106 to rotate synchronously. The rotation of the threaded rod 1106 drives the outer moving part 1108 to slide along the guide rod 1107 towards each other. The positioning rods 1109 on both sides of the moving part 1108 move synchronously, causing the lifting rod 1110, which is movably connected to it, to rotate downward. The end of the lifting rod 1110 away from the positioning rod 1109 is movably connected to the connecting rod 1111. As the lifting rod rotates downward, the end of the lifting rod 1110 away from the positioning rod 1109 rotates downward. When the rod 1110 presses down, the connecting rod 1111 drives the pressing base 1103 to move vertically downward along the sliding plates 1102 on both sides of the rectangular hole. The pressing base 1103 continues to move down until it is in complete contact with the ground. Under the continuous drive of the bidirectional motor 1105, a pre-pressure is generated, thereby evenly transferring the weight of the crane platform 1 to the ground and effectively dispersing the vertical load and horizontal torque generated during the hoisting operation. At this time, the center of gravity of the entire equipment is lowered to the ground through the bottom support component 11, forming a stable support structure and providing a solid foundation for subsequent high-altitude hoisting operations.

[0050] After the bottom support is stabilized, the lifting arm 8 at the top of the crane platform 1 starts the telescopic drive mechanism. The main boom section is first raised to the preset angle. Then the extension rod 9 extends outward from the front end of the lifting arm 8 to further increase the working radius. The moving arm 10 at the front end of the extension rod 9 can be rotated horizontally and the angle can be adjusted, which drives the telescopic device 12 at the front end to move precisely to the area directly above the building material. The drive mechanism built into the telescopic device 12 is activated, and the hook 13 at the bottom end moves down to the appropriate height. The operator places the lifting rope 16, which is pre-connected to the lifting plate 15, on the hook 13, ensuring that the contact position between the lifting rope 16 and the hook 13 is centered and without twisting. At this time, the lifting plate 15 is suspended below the hook 13 by the lifting rope 16 and is in the ready-to-lift state.

[0051] To ensure a safe and reliable connection between the lifting rope 16 and the lifting platform 15, firstly, the two drive motors 1409 on the lifting platform 15 receive a start signal. One drive motor 1409 rotates in the forward direction, and the other rotates in the reverse direction. The power output shaft of the drive motor 1409 drives the rotating rod 1410 to rotate through a coupling. The two ends of the rotating rod 1410 are movably connected to the inner side of the connecting frame 1408. The rotational motion is converted into the horizontal movement of the locking member 1411. Driven by the rotating rod 1410, the two locking members 1411 approach each other, precisely aligning with the locking groove on the fixed retaining member 1412, which is fixedly connected to the lifting rope 16, and gradually being placed into the groove. Subsequently, the telescopic electric rod 1402 is activated, and the telescopic end pushes the sliding ring 1403 to move downward along the outer side of the fixed retaining member 1401 and the sliding groove member 1407. The downward movement of the sliding ring 1403 synchronously drives the tension spring 1405 to be compressed. The sliding ring 1403 contracts to store elastic potential energy for subsequent repositioning. Simultaneously, the bottom end of the sliding ring 1403 remains in continuous contact with the top end of the dislocation detection device 1404. The dislocation detection device 1404 is kept vertical by the guide of the telescopic rod 1406, monitoring the positional changes of the sliding ring 1403 in real time. An alarm is triggered if abnormal dislocation occurs. As the sliding ring 1403 continues to move downwards, the connecting frame 1408 drives the locking member 1411 to further engage within the locking groove. The bottom end of the locking member 1411 contacts the pressing plate 1414 within the locking groove, continuously pressing the pressing spring 1413. The elastic reaction force of the pressing spring 1413 makes the contact between the locking member 1411 and the locking groove even tighter, thus firmly fixing the end of the lifting rope 16 to the lifting plate 15. At this time, the two lifting ropes 16 are symmetrically positioned below the building material, ensuring uniform force during lifting.

[0052] After the positioning is completed, the dislocation detection device 1404 will continuously monitor the position of the sliding ring 1403. If abnormal situations such as the sliding ring 1403 moving upward or the locking part 1411 becoming loose occur during the hoisting process, the dislocation detection device 1404 will immediately send a signal to the control system to trigger the emergency braking procedure to prevent building materials from falling.

[0053] Once all preparations are complete, the lifting boom 8 system initiates its lifting action. The telescopic device 12 drives the hook 13 upward, and the lifting rope 16 tightens accordingly, smoothly lifting the building materials. At this time, the lifting boom 8, extension rod 9, and moving boom 10 work together to transfer the building materials to the target location through angle adjustment and length extension. During the transfer process, the bottom support component 11 continuously provides stable support to ensure that the crane platform 1 does not experience significant settlement or tilting. When the building materials reach the target location, the telescopic device 12 drives the hook 13 to slowly descend, smoothly placing the building materials at the designated landing point. Subsequently, the rope fixation detection component 14 initiates the reset procedure, driving the motor 1409 to rotate in the opposite direction, causing the locking component 1411 to disengage from the locking slot. The telescopic electric rod 1402 retracts, pulling the sliding ring 1403 upward, and the tension spring 1405 resets accordingly. The elastic potential energy of the pressing spring 1413 is released, pushing the pressing plate 1414 back to its initial position.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
