Description

Technical Field

[0001] This invention relates to the field of lifting machinery technology, specifically to a constant tension rope reeling and releasing intelligent automated device. Background Technology

[0002] There are two main types of existing rope winding and unwinding technologies: one is to continuously apply a constant gravity to the main drum at the winding end to obtain the constant tension required for the main drum to wind the rope; the other is to take braking measures at the unwinding end, where the winding drum needs to drive the unwinding drum to rotate when winding the rope, and the unwinding drum always generates a resistance under the braking force of the brake connected at one or both ends. This resistance is the tension required by the winding drum.

[0003] The existing technologies have obvious drawbacks: the first type of winch relies on gravity to obtain constant tension (pull force) when winding the rope, which is difficult to implement except in marine salvage projects where there is a free height of hundreds or thousands of meters; the second type relies on the braking friction force at the rope release end to obtain constant tension, which has many drawbacks such as rapid wear of friction plates, friction heat generation, noise pollution, and unstable braking force.

[0004] As large-scale engineering lifting machinery (truck cranes, crawler cranes, port cranes, offshore floating cranes, etc.) becomes increasingly larger and their lifting heights increase, the winches and wire ropes, as the core components of these machinery, become particularly important. Previously, the ropes wound on large lifting winches lacked pre-tension, resulting in uneven and unstable rope arrangement on multi-layer winches, especially with an unstable foundation for the inner ropes. During lifting operations, this manifested as rope tangling and entrapment, exacerbating friction and damage between the wire ropes, creating significant safety hazards, and increasing the cost of premature rope replacement. Summary of the Invention

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] The embodiments of the present invention are implemented as follows, such as... Figures 1 to 3 The constant tension rope reeling and releasing intelligent automated equipment shown includes:

[0036] Automatic wire feeding machine 3;

[0037] Active take-up machine 12;

[0038] The tensioning traction disc 7 is installed between the active take-up machine 12 and the automatic wire feeding machine 3, and is used to pull the wire rope of the automatic wire feeding machine 3 to the winch of the active take-up machine 12.

[0039] The detection mechanism, connected to the automatic wire feeding machine 3 and the tensioning traction plate 7, is used to detect the tensile force value of the automatic wire feeding machine 3 and the tensioning traction plate 7 under the action of the active wire take-up machine 12 when they are displaced or deformed.

[0040] In practical application, the winch on the active take-up machine 12, driven by a hydraulic motor, begins to rotate and slowly take in the rope. At this time, the movable automatic pay-off machine 3 and the movable tensioning traction disc 7 are temporarily inactive, allowing the rope to be gradually stretched. As the active take-up machine 12 continues to operate, the rope tension gradually increases. Simultaneously, the movable automatic pay-off machine 3 and the movable tensioning traction disc 7 will shift on the track. The tension value can be read through the connected detection mechanism. According to the design principle, the sum of the detected data (hereinafter referred to as resistance) equals the tension at the take-up end. As the tension at the take-up end continuously increases, when it exceeds the design operating value... When the tension is 10%, the movable tensioning traction plate 7 and the movable automatic wire feeding machine 3 begin to move slowly. During this period, the system algorithm adjusts and controls the output torque of the hydraulic motor of the active wire feeding machine 12 and the output torque of the servo motor on the movable automatic wire feeding machine 3 and the movable tensioning traction plate 7 in a timely manner according to the change of resistance value, so as to achieve the balance of overall tension and resistance, thereby maintaining the tension of the wire rope relatively constant throughout the entire wire feeding process. Preferably, the controller 13 has its own system algorithm. The specific algorithm can adopt the existing one. If necessary, a matching electrical electronic control system and cloud storage can be set up, depending on the actual needs.

[0041] like Figure 1 As shown, in a preferred embodiment of the present invention, the detection mechanism includes:

[0042] A first tension detection element, connected to the automatic wire feeding machine 3, is used to detect the tension value experienced by the automatic wire feeding machine 3 when it generates displacement. The first tension detection element includes:

[0043] First-stage spring buffer 1;

[0044] The first-level tension display 2 is connected at one end to the first-level spring buffer 1 and at the other end to the automatic wire feeding machine 3;

[0045] A second tension detection element, connected to the tensioning traction disc 7, is used to detect the tension value experienced by the tensioning traction disc 7 when it undergoes displacement. The second tension detection element includes:

[0046] Secondary spring buffer 5;

[0047] The secondary tension display instrument 6 is connected at one end to the secondary spring buffer 5 and at the other end to the tensioning traction disc 7;

[0048] A testing component, positioned between the tensioning traction disc 7 and the active take-up machine 12, is used to test the wire rope. The testing component includes:

[0049] The intelligent detection camera 8 is installed between the tensioning traction plate 7 and the active take-up machine 12;

[0050] A fixed-length meter 9 is installed between the intelligent detection camera 8 and the active take-up machine 12;

[0051] The controller 13 is connected to the first tension detection element and the second tension detection element.

[0052] In one embodiment, the displacement and corresponding tension value of the automatic wire feeding machine 3 are detected by the cooperation of the primary tension display instrument 2 and the primary spring buffer 1. Similarly, the displacement and corresponding tension value of the tensioning traction plate 7 are detected by the cooperation of the secondary tension display instrument 6 and the secondary spring buffer 5. The primary spring buffer 1 and the secondary spring buffer 5 can be fixed on the track or the ground according to the site conditions. The intelligent detection camera 8 monitors and records the status of the wire rope, and the length meter 9 measures the length of the wire rope, making the winding more accurate.

[0053] like Figure 1 As shown, in another preferred embodiment of the present invention, a first conductor support 4 cooperating with the wire rope is installed between the tensioning traction plate 7 and the automatic wire feeding machine 3, and a second conductor support 10 cooperating with the wire rope is installed between the tensioning traction plate 7 and the active wire take-up machine 12. The second conductor support 10 is installed between the fixed length meter 9 and the active wire take-up machine 12, and an automatic wire laying device 11 is installed between the second conductor support 10 and the active wire take-up machine 12.

[0054] In one embodiment, by setting the first wire guide 4 and the second wire guide 10 to cooperate with the wire rope, the relative stability of the wire rope is ensured throughout the operation. The automatic wire arranger 11 can better facilitate the active wire take-up machine 12 to wind and arrange the wire rope, further improving the stability of the entire rope winding and unwinding process.

[0055] Working principle: When the entire production line starts working, the winch 12 on the active take-up machine begins to rotate slowly to take in the rope under the drive of the hydraulic motor. At this time, the automatic pay-off machine 3 and the tensioning traction plate 7 are temporarily not working, so the wire rope will be gradually stretched. With the continuous operation of the active take-up machine 12, the rope tension gradually increases. At this time, the automatic pay-off machine 3 and the tensioning traction plate 7 will be displaced on the track. The tension value can be read through the primary tension display 2 and the secondary tension display 6 connected to it. According to the design principle, the sum of the data displayed by the primary tension display 2 and the secondary tension display 6 is... (Hereinafter referred to as resistance) is equal to the tension at the take-up end. As the tension at the take-up end increases, when it exceeds the designed tension by 10%, the power system of the automatic wire feeding machine 3 and the tensioning traction disc 7 begins to move slowly. During this period, based on the changes in the tension values ​​of the first-level tension display instrument 2 and the second-level tension display instrument 6, the reading of the resistance magnitude, and the system algorithm, the output torque of the hydraulic motor of the active take-up machine 12 and the output torque of the servo motor of the automatic wire feeding machine 3 and the tensioning traction disc 7 are adjusted in a timely manner to achieve a balance between overall tension and resistance, thereby maintaining a relatively constant tension of the wire rope throughout the entire take-up and take-up process.

[0056] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
