DETAILED DESCRIPTION

[0028] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0030] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0032] In addition, the terms "horizontal", "vertical" and the like do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0033] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0034] At present, when the crane wire rope 001 is detected, the detection equipment is matched with the wire rope 001, and the wire rope 001 continuously moves relative to the detection equipment, so that the wire rope 001 within the set distance can be completely detected. Due to the fact that the wire rope 001 is prone to shaking during detection, the relative position between the wire rope 001 and the detection equipment changes after the wire rope 001 shakes, the wire rope 001 is prone to collision or extrusion with the detection equipment, which affects the normal operation of the detection equipment, and also easily damages the detection equipment, shortening the service life of the detection equipment; and after the wire rope 001 shakes, the wire rope 001 and the detection equipment produce relative displacement, the wire rope 001 is not in the normal detection position, the detection result obtained by the detection equipment is poor in accuracy and reliability, and there is a safety hazard.

[0035] Therefore, the designer designs a follow-up crane wire rope full life cycle safety monitoring system, which can effectively improve the movement of the wire rope 001 relative to the detection device 200 during detection, and the wire rope 001 is not prone to collision and extrusion with the detection device 200, and the detection device 200 is not prone to damage. At the same time, the wire rope 001 can always be located in the appropriate detection area, and the detection result is high in accuracy and reliability.

[0036] It should be noted that the monitoring system is used to detect the steel wire rope 001 wound on the crown block drum, the crown block drum is installed on the crown block top beam, the crown block top beam is fixedly connected with the crown block beam, the crown block drum is driven by a motor and can rotate to drive the steel wire rope 001 to move.

[0038] The working principle of the follow-up type crane steel wire rope whole life cycle safety monitoring system provided in this embodiment is as follows:

[0039] When cooperating with the steel wire rope 001 to detect the damage of the steel wire rope 001, the force generated by the swing of the steel wire rope 001 is transmitted to the rack 100 through the force transmission device 400, and then transmitted to the swinging device 300 through the rack 100, so that the whole monitoring system swings with the steel wire rope 001, in this way, the relative position between the steel wire rope 001 and the detection device 200 will not change, and the steel wire rope 001 will not collide or be extruded with the detection device 200, so that the detection device 200 is not easy to be damaged. At the same time, during the detection process, since the relative position between the steel wire rope 001 and the detection device 200 is not easy to change, the detection device 200 can better detect the whole steel wire rope 001, so that the partial missed detection or incomplete detection of the steel wire rope 001 is not easy to occur, the accuracy of the detection result is high, and the reliability is high.

[0045] It should be understood that the magnetic loading mechanism 210 and the magnetic detection mechanism 220 can all adopt the existing known structure, and the specific description is not performed in the embodiment in order to avoid repeated and tedious description.

[0046] It should be noted that the magnetic loading mechanism 210 and the magnetic detection mechanism 220 are connected with the first mounting beam 120 and the second mounting beam 130 respectively, the relative positions of the two are stable and can move together with the jig 100.

[0047] Please combine Figure 1 and Figure 2In the embodiment, the swing device 300 includes a first tension spring assembly 310, a second tension spring assembly 320, and a support joint 330. It should be noted that the number of the crown beams is two, which are a first crown beam 002 and a second crown beam 003 for the convenience of description, and the steel wire rope 001 is located between the two crown beams.

Moreover, the first axis and the axis of the positioning shaft 331 extend along the second direction 005, and the second axis and the third axis extend along the first direction 004. By arranging the support joint 330, the support joint 330 can bear the gravity of the rack 100, the detection device 200, and the force transmission device 400 while meeting the swing of the rack 100 with the steel wire rope 001, thereby reducing the load of the first tension spring assembly 310 and the second tension spring assembly 320 and improving the stability and safety of the overall structure.

[0049] Further, the first swing arm 332 and the second swing arm 333 are arranged at an included angle, so that the included angle between the first swing arm 332 and the second swing arm 333 can be adaptively increased or decreased during the swing of the rack 100 with the steel wire rope 001, thereby preventing the first swing arm 332 and the second swing arm 333 from interfering with each other and affecting the free swing of the steel wire rope 001, and improving the adaptability.

[0050] Please combine Figure 4 Further, the positioning shaft 331 comprises a first shaft segment 3311 and a second shaft segment 3312 which are integrated, the outer diameter of the first shaft segment 3311 is larger than that of the second shaft segment 3312, so that the connection part of the first shaft segment 3311 and the second shaft segment 3312 forms an annular abutting surface 3313.

[0053] Further, the power transmission wheel 420 is provided with an annular positioning groove for the steel wire rope 001 to pass through, the steel wire rope 001 passes through the annular positioning groove, which can better position the steel wire rope 001, so that the force generated by the shaking of the steel wire rope 001 can be transmitted to the power transmission wheel 420 in time, and the power transmission wheel 420 can make feedback in time. It should be understood that the annular positioning groove can participate in forming the passing channel 430.
