DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] Combine Figures 1 to 7A shackle remote control releasing device shown includes a U-shaped shackle 10, an outer box 20 is provided at one end of the shackle 10, an outer box front cover 30 is provided at one end of the outer box 20, a shackle bolt 40 is provided through the bottom of the shackle 10 and the bottom of the outer box 20, a battery pack 50 is provided on the inner wall of the outer box 20, a remote control circuit 60 is provided on the inner wall of the outer box front cover 30, a power component 70 is provided on the inner wall of the outer box front cover 30 above the shackle bolt 40, an outer box accessory compartment 80 is provided at the bottom of the outer box 20 and is sleeved on the outer ring of the shackle bolt 40, a limiting component 90 is provided on the inner wall of the outer box 20 above the shackle bolt 40, and an outer box cover plate 100 is provided on one side of the outer box 20.

[0031] Two groups of connecting columns 101 are provided on the outer surface of one end of the shackle 10. The connecting columns 101 are used to be screwed to the outer box 20 to ensure the stability of the shackle 10. A light hole 102 is provided at the lower end, and a plug-in board 104 is provided below the connecting columns 101. The plug-in board 104 is plugged into and screwed to the bottom of the outer box 20 to facilitate the installation of the shackle 10 and further improve the stability. A threaded hole 103 is provided at the lock buckle at the other end of the shackle 10.

[0032] The shackle bolt 40 is provided with a gear thread combination section 401, a first thread section 402, an optical axis section 403 and a second thread section 404 in sequence from the head end to the tail end. The second thread section 404 is connected in conjunction with the threaded hole 103. This multi-section design enables the shackle bolt 40 to play a key role in the device. The gear thread combination section 401 cooperates with the gear of the power component 70 to achieve precise driving of the shackle bolt 40; the design of the optical axis section 403 reduces the friction between the shackle bolt 40 and other lifting rigging, avoids damage to other rigging, and ensures that the withdrawal action of the shackle bolt is smoother; the second thread section 404 is closely matched with the threaded hole 103 to ensure the firmness of the shackle in the locked state. The shackle bolt with this structural design can accurately perform unlocking and locking operations under the drive of the power component 70, thereby improving the reliability and safety of the device.

[0033] The front end of the shackle bolt 40 is provided with an oblate block 405 with a hole. When the remote control device fails, the shackle bolt 40 can be rotated by hand or by inserting a rod-shaped object into the hole, thereby improving the fault tolerance rate.

[0034] The power assembly 70 includes a connecting component 701 installed on the inner side wall of the outer box front cover 30, and a motor 702 is provided on the back side of the connecting component 701. The connecting component 701 firmly installs the motor 702 on the outer box front cover 30 to ensure that the motor 702 does not shake during operation, thereby improving the stability of the transmission. The output end of the motor 702 passes through the connecting component 701 and is provided with a first gear 703. A second gear 704 is provided below the first gear 703 in the connecting component 701. The first gear 703 and the second gear 704 are meshed and transmitted, and the two have the same specifications. In this way, a gear with a smaller diameter is selected. Not only can it save space and optimize the device structure, but it can also avoid the impact of speed change and torque reduction on the use of the device. The second gear 704 is used as an intermediate wheel to transmit torque, and the same gear design is also convenient for production and maintenance; the second gear 704 is engaged with the gear thread combination section 401 of the shackle bolt 40 for transmission, so that the power of the motor 702 can be accurately transmitted to the shackle bolt 40 to realize its rotational movement. The power component 70 provides powerful power for the remote control release of the shackle. At the same time, the remote control function of the motor 702 allows the operator to operate at a distance, thereby improving the safety and convenience of work.

[0035] The inner cavity of the outer box accessory bin 80 is provided with a nut 801, and the nut 801 is matched with the gear thread combination section 401 and the first thread section 402 to make the shackle bolt 40 rotate in a spiral manner. The inner cavity of the outer box accessory bin 80 is provided with a wave spring 802 on one side of the nut 801, and a retaining ring 803 is provided on the other side of the wave spring 802. The setting of the retaining ring 803 can prevent the nut 801 from axial displacement during the movement, ensuring that the nut 801 and the shackle bolt 40 maintain a good match. The retaining ring 803 is embedded in the inner wall of the outer box accessory bin 80. When the shackle bolt 40 spirally advances to contact the shackle bolt, the threaded inlet of the shackle bolt 40 does not necessarily coincide with the inlet of the threaded hole 103 in the shackle 10, so the shackle bolt 40 0 will continue to spiral forward under the drive of the motor 702. Since the rigidity of the shackle 10 itself will prevent the shackle bolt 40 from advancing, the nut 801 will be subjected to the reaction force of the shackle bolt 40 and retreat, thereby causing the wave spring to be compressed. In this way, there will be an angle redundancy in the screw-in angle of the shackle bolt 40 and the threaded hole 103 of the shackle 10; when the threaded inlet of the shackle bolt 40 coincides with the inlet of the threaded hole 103, the shackle bolt 40 is screwed into the shackle threaded hole 103 and continues to spiral forward until the locking action is completed. This structural design allows the shackle bolt 40 to rely on the power of the rotation of the motor 702 to realize its own screwing in and out action, thereby realizing the function of releasing the shackle 10, and demonstrating safety and practicality.

[0036] The limit assembly 90 includes two sets of limit switches 901 arranged in mirror-image configuration. The limit switch 901 is installed on the inner wall of the outer box 20. A limit ring 902 is provided at the junction of the first threaded section 402 and the optical axis section 403 in the shackle bolt 40. The limit ring 902 is fixedly connected to the shackle bolt 40. The motor 702 rotates forward to drive the first gear 703 to engage the second gear 704 to rotate, thereby driving the shackle bolt 40 to rotate forward into the threaded hole 103. The limit ring 902 moves with the shackle bolt 40. When the limit ring 902 touches the limit switch 901 on the right, the trigger arm will be lifted, and the limit switch 901 will send a signal to the remote control circuit 60. The remote control circuit 60 cuts off the power supply to the motor 702, and the shackle bolt 40 stops moving and is no longer screwed in. , completing the locking action of the shackle 10; the motor 702 reverses to drive the first gear 703 to engage the second gear 704 to rotate, thereby driving the shackle bolt 40 to reverse and exit the threaded hole 103, and the limit ring 902 retreats with the shackle bolt 40. When it touches the left limit switch 901, it will lift the trigger arm, and the limit switch 901 sends a signal to the remote control circuit 60. The remote control circuit 60 cuts off the power supply to the motor 702, and the shackle bolt 40 stops moving, completing the unlocking action of the shackle 10. This limit function can effectively prevent damage to the device due to excessive movement of the shackle bolt 40, thereby improving the reliability and safety of the device. At the same time, the precise control of the limit switch also makes the unlocking and locking positions of the shackle 10 more accurate, thereby improving work efficiency.

[0037] A signal receiving module and a motor drive circuit are provided inside the remote control circuit 60. The signal receiving module can receive remote wireless signals. The signal receiving module is connected to the motor drive circuit, and the motor drive circuit is connected to the motor 702 to achieve remote control. The design of the remote control circuit 60 enables the operator to unlock and lock the shackle 10 from a distance, greatly improving the convenience and safety of the work.

[0038] The battery pack 50 is electrically connected to the remote control circuit 60 , which is electrically connected to the limit switch 901 . The limit switch provides a control signal, and the remote control circuit 60 controls the motor 702 .
