Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting slings, and specifically relates to a lifting sling retraction structure. Background Technology
[0002] Lifting locks are devices or accessories used in lifting operations to fix and lock lifting equipment such as slings, hooks, etc. Their main function is to ensure safety and stability during the lifting process and prevent accidents such as falling objects, equipment damage, or personal injury caused by loosening or falling of lifting equipment. Lifting locks typically include shackles, hooks, locking mechanisms, etc. They are used in conjunction with slings, chains, and rings to achieve a firm connection and lock on the lifted items. The deployment and retraction operation refers to the process of unfolding and retracting the locks during lifting operations. This operation can effectively improve lifting efficiency and reduce safety hazards caused by loosening or falling of goods.
[0003] However, existing lifting locks typically use a single lifting rope for hoisting. When using a single rope, the wire rope has to bear the entire weight of the hoisting object. This leads to concentrated stress on the wire rope, which can cause uneven tension. The single wire rope will be subjected to greater tension during hoisting, which may cause it to break or wear more quickly, thus reducing its service life and safety. Furthermore, single-rope hoisting has fewer lifting points, which can easily cause the hoisted object to sway in the air, increasing instability and risk during the hoisting process. Utility Model Content
[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a lifting sling retraction structure to solve the problems mentioned in the background art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A hoisting sling take-up and release structure includes a main board, with take-up and release components fixedly connected to both sides of the lower end of the main board. A uniform distribution component is mounted on the lower end of the main board at a support for the take-up and release components. A locking component is slidably connected to the outer surface of the take-up and release components. The take-up and release components include a take-up and release frame mounted at the lower end of the main board. A shaft is rotatably connected to the inner side of the take-up and release frame. A take-up roller is fixedly connected to the outer surface of the shaft. A wire rope is mounted on the outer surface of the take-up roller. A take-up and release seat is fixedly connected to the lower end of the main board. The other end of the wire rope is fixedly connected to the take-up and release seat. A take-up and release motor is fixedly connected to the outer surface of the take-up and release frame. The output shaft of the take-up and release motor passes through the take-up and release frame and is fixedly connected to the shaft. The wire rope is slidably connected to the uniform distribution component and the locking component.
[0007] As a preferred technical solution, the uniformizing component includes a uniformizing groove formed at the lower end of the main board, a uniformizing screw rotatably connected inside the uniformizing groove, a threaded component threadedly connected to the outer surface of the uniformizing screw, a uniformizing frame fixedly connected to the lower end of the threaded component, a uniformizing pulley rotatably connected to the inner side of the uniformizing frame, and a steel wire rope slidingly connected to the uniformizing pulley.
[0008] As a preferred technical solution, a control slot is provided at the lower end of the main board, and a driven bevel gear is fixedly connected to the other end of the uniform screw through the control slot. A uniform motor is fixedly connected to the lower end of the main board, and a driving bevel gear is fixedly connected to the output shaft of the uniform motor. The driving bevel gear and the driven bevel gear are meshed with each other.
[0009] As a preferred technical solution, a connector is fixedly connected to the upper end of the motherboard, a connecting rod is fixedly connected to the upper end of the connector, and a connecting ring is fixedly connected to the upper end of the connecting rod.
[0010] As a preferred technical solution, the lower end of the connecting rod is fixedly connected to a mounting plate. The outer surface of the mounting plate is provided with multiple mounting through holes. Mounting screws are inserted into the mounting through holes and are threadedly connected to the connecting seat through the mounting through holes.
[0011] As a preferred technical solution, the lock assembly includes a connecting frame, a lower pulley is rotatably connected to the lower inner side of the connecting frame, an upper pulley is rotatably connected to the upper inner side of the connecting frame, the wire rope is located between the upper and lower pulleys, the outer ring of a bearing is fixedly connected to the lower end of the connecting frame, and a hook is fixedly connected to the inner ring of the bearing.
[0012] As a preferred technical solution, support rods are fixedly connected to both sides of the connecting frame, and support pulleys are rotatably connected to the inner side of each support rod. Limiting grooves are formed on the outer surface of each support pulley, and the wire rope is slidably connected inside the limiting grooves.
[0013] In summary, the present invention has the following main advantages:
[0014] Firstly, this utility model, through its designed retraction and release components, allows for normal use by passing the end of the wire rope through a uniform pulley, and then through the locking assembly and the retraction and release base. The locking assembly is used to hook the item, and the retraction and release motor drives the retraction roller to retract, thus lifting the item while the roller is retracting and releasing it while it is rotating in the opposite direction. Furthermore, by splitting a single wire rope into two strands, this utility model increases the load-bearing capacity during use, preventing wire rope breakage or accelerated wear, thereby increasing the service life of the retraction and release structure.
[0015] Secondly, this utility model, through the setting of the uniform component, will also start the uniform motor when the take-up and take-down motor is in use. The uniform motor drives the active bevel gear to rotate, and the rotation of the active bevel gear drives the driven bevel gear to rotate, which in turn drives the uniform screw to rotate. This rotation of the uniform screw drives the threaded part to move, and the movement of the threaded part drives the uniform frame to move, which in turn moves the uniform pulley. This allows the wire rope to be guided to be wound onto the surface of the take-up roller during use, so that the wire rope can be wound evenly onto the surface of the take-up roller. Furthermore, the uniform screw is set to reciprocate, so that the uniform frame can move back and forth under the rotation of the uniform motor, which facilitates the winding effect of the wire rope.

[0021] Example
[0022] refer to Figures 1 to 4This embodiment of a hoisting sling take-up and release structure includes a main board 1. Take-up and release components 2 are fixedly connected to both sides of the lower end of the main board 1. A uniform distribution component 6 is provided at the lower end of the main board 1 on the support of the take-up and release component 2. A locking component 7 is slidably connected to the outer surface of the take-up and release component 2. The take-up and release component 2 includes a take-up and release frame 21 provided at the lower end of the main board 1. A shaft 23 is rotatably connected to the inner side of the take-up and release frame 21. A take-up roller 24 is fixedly connected to the outer surface of the shaft 23. A wire rope 25 is provided on the outer surface of the take-up roller 24. A take-up and release seat 26 is fixedly connected to the lower end of the main board 1. The other end of the wire rope 25 is fixedly connected to the take-up and release seat 26. A take-up and release motor 22 is fixedly connected to the outer surface of the take-up and release frame 21. The output shaft of the take-up and release motor 22 passes through the take-up and release frame 21 and is fixedly connected to the shaft 23. The wire rope 25 is slidably connected to the uniform distribution component 6 and the locking component 7.
[0023] refer to Figure 2 and Figure 3 The uniformizing component 6 includes a uniformizing groove 61 located at the lower end of the main board 1. A uniformizing screw 62 is rotatably connected inside the uniformizing groove 61. A threaded component 63 is threaded onto the outer surface of the uniformizing screw 62. A uniformizing frame 64 is fixedly connected to the lower end of the threaded component 63. A uniformizing pulley 65 is rotatably connected to the inner side of the uniformizing frame 64. A steel wire rope 25 is slidably connected to the uniformizing pulley 65. A control groove 66 is located at the lower end of the main board 1. A driven bevel gear 67 is fixedly connected to the other end of the uniformizing screw 62 through the control groove 66. A uniformizing motor is fixedly connected to the lower end of the main board 1. 69. The output shaft of the uniform motor 69 is fixedly connected to a drive bevel gear 68, which meshes with a driven bevel gear 67. The uniform motor drives the drive bevel gear 68 to rotate, which in turn drives the driven bevel gear 67 to rotate, thereby driving the uniform screw 62 to rotate. This rotation of the uniform screw 62 causes the threaded component 63 to move, which in turn causes the uniform frame 64 to move, which in turn causes the uniform pulley 65 to move. This allows the wire rope 25 to be wound onto the surface of the take-up roller 24 during use.
[0024] refer to Figure 1 A connecting seat 3 is fixedly connected to the upper end of the main board 1. A connecting rod 4 is fixedly connected to the upper end of the connecting seat 3. A connecting ring 5 is fixedly connected to the upper end of the connecting rod 4. A mounting plate 8 is fixedly connected to the lower end of the connecting rod 4. Multiple mounting through holes 9 are opened on the outer surface of the mounting plate 8. Mounting screws 10 are inserted into the mounting through holes 9. The mounting screws 10 pass through the mounting through holes 9 and are threadedly connected to the connecting seat 3. The connecting ring 5 allows for the installation of the retractable structure, and the mounting screws 10 make the installation of the retractable structure more convenient.
[0025] refer to Figures 1-4The lock assembly 7 includes a connecting frame 71. A lower pulley 72 is rotatably connected to the lower inner side of the connecting frame 71, and an upper pulley 73 is rotatably connected to the upper inner side of the connecting frame 71. A steel wire rope 25 is located between the upper pulley 73 and the lower pulley 72. The outer ring of a bearing 74 is fixedly connected to the lower end of the connecting frame 71, and a hook 75 is fixedly connected to the inner ring of the bearing 74. The lock assembly 7 is configured to connect the hook 75 to the steel wire rope 25 under the action of the upper pulley 73 and the lower pulley 72. The clamping connection between the upper pulley 73 and the lower pulley 72 increases the stability of the lock assembly 7, and allows the lock assembly 7 to slide on the surface of the steel wire rope 25.
[0026] refer to Figure 4 Both sides of the connecting frame 71 are fixedly connected to support rods 11, and the inner side of each support rod 11 is rotatably connected to a support pulley 12. The outer surface of each support pulley 12 is provided with a limiting groove 13, and the wire rope 25 is slidably connected inside the limiting groove 13. The support pulley 12 provides support for the wire rope 25 during use, allowing the wire rope 25 to slide within the lock assembly 7.
[0027] Operating principle and advantages: First, the connecting ring 5 facilitates the installation of the retractable structure, and the mounting screws 10 make installation easier. Then, the end of the wire rope 25 is passed through the uniform pulley 65, and then through the locking assembly 7 and the retractable base 26. After installation, the device can be used normally. The locking assembly 7 is used to hook the item, and the retractable motor 22 drives the winding roller 24 to wind it up. This allows the item to be lifted while the winding roller 24 is winding, and released while it is rotating in the opposite direction. This invention also utilizes the technique of splitting a single wire rope 25 into two strands to achieve the desired effect. The increased load-bearing capacity prevents the wire rope 25 from breaking or experiencing accelerated wear, thus extending the service life of the winding structure. During winding, the uniform motor 69 drives the active bevel gear 68 to rotate, which in turn drives the driven bevel gear 67 to rotate, causing the uniform screw 62 to rotate. This rotation of the uniform screw 62 then moves the threaded component 63, which in turn moves the uniform frame 64, causing the uniform pulley 65 to move as well. This guides the wire rope 25 to be wound evenly onto the surface of the winding roller 24, making it more convenient to use.
