Since the state of the follow-up rod is closely related to the swinging of the sling, the real-time inclination of the sling can be accurately calculated through the real-time detected inclination of the follow-up rod, thereby providing accurate angle parameters for the hoisting operation, ensuring accurate positioning and control in the hoisting process, avoiding safety hazards caused by abnormal inclination of the sling, and improving the safety of the hoisting operation. The upper end of the fixed component of the transmission mechanism is fixedly connected with the cross beam and located between the follow-up rod and the sling, thereby providing stable support for the entire transmission link.

This structural design cleverly solves the problem that the fixed-end-free sling is difficult to directly detect the inclination, and provides an effective inclination monitoring means for the hoisting operation of the fixed-end-free sling through the combination of mechanical transmission and angle measurement, which helps to improve the safety and stability of the hoisting process.

DETAILED DESCRIPTION

[0029] In order to make the above objectives, features and advantages of the present application more obvious and comprehensible, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Although some embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms, and should not be interpreted as being limited to the embodiments set forth herein, rather, these embodiments are provided to make the present application more thorough and complete. It should be understood that the drawings and embodiments of the present application are only for exemplary purposes, and are not intended to limit the scope of protection of the present application.

[0030] The term "comprising" and variations thereof as used herein are open-ended, that is "including, but not limited to"; the term "based on" is "based, at least in part, on"; the term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one additional embodiment"; the term "some embodiments" means "at least some embodiments"; the term "optional" means "optional in at least some embodiments". Related definitions are given throughout the description. It should be noted that the concepts "first", "second", etc. mentioned in the present application are only used to distinguish different devices, modules or units, and are not intended to limit the order or interdependence of the functions performed by these devices, modules or units.

[0031] It should be noted that the modification of "one" and "multiple" mentioned in the present application is illustrative but not restrictive, and those skilled in the art should understand that unless otherwise explicitly indicated in the context, it should be understood as "one or more".

[0032] In the related art, the traditional fixed rope hoisting system is to fix one end of the hoisting rope and control the winding and unwinding through the pulley and winch. The hoisting system with no fixed end of the hoisting rope connects both ends of the hoisting rope to the winch drum, and operates the winding and unwinding through the drum rolling. This way shows higher flexibility in actual application because it does not need a specific fixed point, so it is widely used. However, the hoisting system with no fixed end of the hoisting rope has obvious defects. In terms of inclination detection, the traditional fixed rope hoisting system can install a device at the fixed end of the hoisting rope to detect the inclination. However, the hoisting rope with no fixed end is in an up-and-down active state, and there is no fixed position for installing an inclination sensor, so the operator cannot obtain the dynamic change of the inclination of the hoisting rope in time. In the hoisting operation, the inclination of the hoisting rope is a key factor related to safety. If the inclination cannot be grasped, the operator may have difficulty in judging the balance state and movement trend of the hoisted object, which increases the risk of safety accidents such as shaking, tilting and even falling during hoisting, and seriously affects the safety of the hoisting operation.

[0033] In view of the problems in the above related art, the present application provides a fixed-end-free hoisting rope inclination detection device and method. The following will be described in detail in combination with specific embodiments.

[0034] As shown in Figure 1 and 2 , the fixed-end-free hoisting rope inclination detection device provided by the embodiments of the present application is applied to a hoisting system using a fixed-end-free hoisting rope 3. The fixed-end-free hoisting rope inclination detection device comprises a measuring mechanism 1 and a transmission mechanism 2. The measuring mechanism 1 comprises a follow-up rod 11 and an inclination sensor 12. One end of the follow-up rod 11 is used for rotating connection with a cross beam 4 on which the hoisting rope 3 is installed. The other end of the follow-up rod 11 is freely hanging. The inclination sensor 12 is arranged on the follow-up rod 11 and is used for detecting the inclination of the follow-up rod 11. The transmission mechanism 2 comprises a fixed component 21 and a transmission component 22. The upper end of the fixed component 21 is used for fixed connection with the cross beam 4 on which the hoisting rope 3 is installed and is arranged between the follow-up rod 11 and the hoisting rope 3. A guide through hole is formed in the fixed component 21 along the horizontal direction. The transmission component 22 is arranged in the guide through hole. One end of the transmission component 22 is in contact with the hoisting rope 3, and the other end of the transmission component 22 is in contact with the follow-up rod 11.

[0035] Specifically, one end of the follower rod 11 of the measuring mechanism 1 is rotationally connected with the beam 4 on which the hoisting rope 3 is installed, and such a connection mode enables the follower rod 11 to flexibly rotate relative to the beam 4, and the other end freely hangs down to ensure that it can naturally swing when subjected to force. The inclination sensor 12 is installed on the follower rod 11 and can detect the inclination change of the follower rod 11 in real time, and then calculate the inclination change of the hoisting rope 3 according to the inclination of the follower rod 11. The upper end of the fixed component 21 of the transmission mechanism 2 is connected with the beam 4 on which the hoisting rope 3 is installed, and the fixed component 21 and the beam 4 can be connected through a connecting piece, and the fixed component 21 is arranged between the follower rod 11 and the hoisting rope 3 to provide stable support for the transmission component 22. The guide through hole opened in the horizontal direction in the fixed component 21 provides an accurate guide path for the movement of the transmission component 22, so that the transmission component 22 keeps horizontal movement in the guide through hole, avoids the inclination of the transmission component 22 to cause errors in the inclination calculation of the hoisting rope 3, and improves the accuracy of the inclination detection of the hoisting rope 3. The transmission component 22 passes through the guide through hole, one end of which is in contact with the hoisting rope 3, and when the hoisting rope 3 swings or inclines, the movement of the hoisting rope 3 can be transmitted to the transmission component 22, so that it moves in the horizontal direction, and the other end of the transmission component 22 is in contact with the follower rod 11, so as to transmit the horizontal movement of the hoisting rope 3 to the follower rod 11 through the transmission component 22, so that the follower rod 11 inclines, and the inclination of the follower rod 11 is detected by the inclination sensor 12 arranged on the follower rod 11, so as to calculate the current corresponding inclination of the hoisting rope 3 according to the detected inclination.

[0036] In this embodiment, one end of the follow-up rod 11 is rotatably connected with the cross beam 4, and the other end is freely hanging, and one end of the transmission assembly 22 contacts the sling rope 3, and the other end contacts the follow-up rod 11. Through the transmission assembly 22, the slight dynamic change of the sling rope 3 can be transmitted to the follow-up rod 11 in real time, so that the follow-up rod 11 can swing through the transmission assembly 22 to follow the sling rope 3, so that the swing change of the sling rope 3 can be accurately mapped through the swing of the follow-up rod 11. In combination with the inclination sensor 12 arranged on the follow-up rod 11, the inclination data of the follow-up rod 11 can be directly obtained. Since the state of the follow-up rod 11 is closely related to the swing of the sling rope 3, the real-time inclination of the sling rope 3 can be accurately calculated through the real-time detected inclination of the follow-up rod 11, so as to provide accurate angle parameters for the hoisting operation, guarantee the accurate positioning and control of the hoisting process, avoid the safety hidden danger caused by the abnormal inclination of the sling rope 3, and improve the safety of the hoisting operation. The upper end of the fixed assembly 21 of the transmission mechanism 2 is fixedly connected with the cross beam 4 and located between the follow-up rod 11 and the sling rope 3, thereby providing stable support for the whole transmission link. At the same time, the horizontal direction guide hole restricts the transmission assembly 22, so that the horizontal movement of the transmission assembly 22 is more stable and standardized, the error caused by shaking and deviation is reduced, and the accuracy of the inclination detection is improved. Through this structure design, the problem of difficult direct detection of the inclination of the fixed-end-free sling rope 33 is ingeniously solved. Through the combination of mechanical transmission and angle measurement, an effective inclination monitoring means is provided for the hoisting operation of the fixed-end-free sling rope 33, which helps to improve the safety and stability of the hoisting process.

[0037] Optionally, as Figure 1 、 2The transmission assembly 22 comprises a first transmission rod 221, a second transmission rod 222, a third transmission rod 223 and a fourth transmission rod 224, a first end of the first transmission rod 221 is connected with a first end of the third transmission rod 223, a second end of the first transmission rod 221 is connected with a first end of the fourth transmission rod 224, a first end of the second transmission rod 222 is connected with a second end of the third transmission rod 223, a second end of the second transmission rod 222 is connected with a second end of the fourth transmission rod 224, the first transmission rod 221 and the second transmission rod 222 have the same length, the fixed assembly 21 comprises a first fixed body 2101 and a second fixed body 2102, an upper end of the first fixed body 2101 is used for being connected with the cross beam 4, an upper end of the second fixed body 2102 is used for being connected with the cross beam 4, the first fixed body 2101 is provided with a first guide through hole along the horizontal direction, the second fixed body 2102 is provided with a second guide through hole along the horizontal direction, the first transmission rod 221 is arranged in the first guide through hole, the second transmission rod 222 is arranged in the second guide through hole, a rod body of the third transmission rod 223 is used for being in contact with the hanging rope 3, a rod body of the fourth transmission rod 224 is in contact with the follow-up rod 11.

[0038] Specifically, the transmission assembly 22 is composed of a first transmission rod 221, a second transmission rod 222, a third transmission rod 223 and a fourth transmission rod 224. The first end of the first transmission rod 221 is connected with the rod body on one side of the first end of the third transmission rod 223, and the second end of the first transmission rod 221 is connected with the rod body on one side of the first end of the fourth transmission rod 224, so that the first transmission rod 221 is located between the third transmission rod 223 and the fourth transmission rod 224. Similarly, the first end of the second transmission rod 222 is connected with the rod body on one side of the second end of the third transmission rod 223, and the second end of the second transmission rod 222 is connected with the rod body on one side of the second end of the fourth transmission rod 224, so that the second transmission rod 222 is located between the third transmission rod 223 and the fourth transmission rod 224. Thus, a certain distance is maintained between the first transmission rod 221 and the second transmission rod 222, which can improve the stability of the transmission assembly 22. In addition, the first transmission rod 221 and the second transmission rod 222 have the same length, so that a stable connection relationship is formed between the transmission rods. The third transmission rod 223 is directly in contact with the hoisting rope 3, and can first perceive the small displacement of the hoisting rope 3, such as the change of the inclination angle and the shaking. Then, the third transmission rod 223 accurately and accurately transmits the displacement to the fourth transmission rod 224 through the rigid connection of the first and second transmission rods 222. For example, if the hoisting rope 3 is inclined, the third transmission rod 223 will be subjected to a horizontal pushing force from the hoisting rope 3, which will cause a horizontal displacement of the third transmission rod 223. This force will be transmitted to the fourth transmission rod 224 through the two transmission rods with the same length, so that the fourth transmission rod 224 also generates a horizontal displacement, and the fourth transmission rod 224 pushes the follower rod 11 in contact with it to swing.

[0039] Further, the fixing assembly 21 is divided into a first fixing body 2101 and a second fixing body 2102, and the upper ends of the two are connected with the cross beam 4. The fixing assembly 21 and the cross beam 4 can be connected through a connecting piece, so that a certain distance is maintained between the fixing assembly 21 and the cross beam 4, which is conducive to the calculation of the inclination angle of the hoisting rope 3. Through the cooperation of the double fixing bodies with the first transmission rod 221 and the second transmission rod 222 of the transmission assembly 22, the stability of the entire transmission mechanism 2 is enhanced, and the transmission assembly 22 passing through is prevented from deviating during movement, so as to ensure the accuracy of the final inclination angle calculation of the hoisting rope 3. In addition, a first guide through hole is formed in the first fixing body 2101 for the first transmission rod 221 to pass through, and a second guide through hole is formed in the second fixing body 2102 for the second transmission rod 222 to pass through. The movement track of the first transmission rod 221 and the second transmission rod 222 is strictly limited through the horizontal guide through hole, so that they can only move linearly in the horizontal direction. Under the complex working conditions of the frequent change of the inclination angle of the hoisting rope 3, the guide through hole avoids the up-down and left-right irregular shaking of the transmission rod, makes the transmission action more accurate, reduces the measurement error caused by the irregular movement of the transmission rod, and thus ensures the accuracy of the inclination angle calculation of the hoisting rope 3.

[0040] In the optional embodiment, the transmission assembly 22 composed of the first transmission rod 221, the second transmission rod 222, the third transmission rod 223 and the fourth transmission rod 224, due to the equal length design of the first transmission rod 221 and the second transmission rod 222, the force is evenly dispersed in the transmission process, and each transmission rod can work stably and maintain stable transmission efficiency. Moreover, the first fixed body 2101 and the second fixed body 2102 are respectively provided with horizontal first guide through holes and second guide through holes, and the two transmission rods respectively pass through the corresponding guide through holes, and the transmission rods are limited by the double guide structure, which can more accurately constrain the movement direction of the transmission rods, so that they strictly follow the horizontal straight line movement, avoiding the deviation of the transmission rods, making the mapping relationship between the transmission action and the actual state of the hoisting rope 3 more accurate, and further making the follower rod 11 can accurately swing with the hoisting rope 3, improving the accuracy of calculating the inclination angle of the hoisting rope 3 through the inclination angle of the follower rod 11.

[0041] Optionally, as shown in Figure 1 and 2 The fixed assembly 21 further comprises a first connecting rod 2105 and a second connecting rod 2106, one end of the first connecting rod 2105 is connected with the upper end of the first fixed body 2101, the other end of the first connecting rod 2105 is connected with the cross beam 4, one end of the second connecting rod 2106 is connected with the upper end of the second fixed body 2102, the other end of the second connecting rod 2106 is connected with the cross beam 4, and the first connecting rod 2105 and the second connecting rod 2106 have the same length.

[0042] In the optional embodiment, the first fixed body 2101 and the second fixed body 2102 are connected with the cross beam 4 through the equal length first connecting rod 2105 and the second connecting rod 2106, so that the first fixed body 2101 and the second fixed body 2102 are located on the same horizontal plane below the cross beam 4, further making the first transmission rod 221 and the second transmission rod 222 passing through them keep stable horizontal movement, so that the horizontal displacement generated by the swing of the hoisting rope 3 can be accurately transmitted to the follower rod 11, improving the accuracy of the inclination angle detection of the hoisting rope 3. Moreover, through the connection of the first connecting rod 2105 and the second connecting rod 2106, the fixed assembly 21 and the cross beam 4 can maintain a certain distance, thereby reducing the influence of the error caused by the distance relationship on the angle calculation, and ensuring the accuracy of the hoisting angle detection.
