Description

Technical Field

[0001] This utility model relates to the field of high-altitude protective gear technology, specifically to an adaptive opening and closing locking anchor hook device for high-altitude operations. Background Technology

[0002] In high-altitude operations, anchor hooks are crucial equipment for ensuring workers reach the work surface. Existing anchor hooks are typically manually operated, making them incompatible with modern technology and presenting the following problems: 1. Inconvenient operation: In high-altitude environments, manual operation requires the first worker to engage and lock the hook, and the last worker to disengage and remove it; 2. Poor timeliness: Traditional hook engagement and disengagement methods are inefficient and cannot meet the demands of modern technology; 3. Insufficient safety: The first worker to engage the anchor hook and the last worker to disengage it cannot completely avoid operational risks, posing safety hazards.

[0003] Therefore, there is an urgent need for a hook device that can quickly open and close the lock to improve the safety and efficiency of high-altitude operations. Utility Model Content

[0004] In view of the above-mentioned technical problems in related technologies, this utility model provides an adaptive opening and closing locking anchor hook device for high-altitude operations, which can solve the above problems.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] The adaptive opening and closing locking anchor hook device for high-altitude operations includes a hook body and an unlocking linkage rod. A double boom is fixedly installed on one side of the hook body. A lock head body is hinged to the bottom of the double boom body via a pin. A slot is opened at the top of the lock head body. A slider constraint housing is fixed to the top of the hook body by bolts. Inside the slider constraint housing, from left to right, a gap adjustment slider A, a gap adjustment slider B, and a lock head locking block are sequentially embedded and slidably arranged. Square sleeves A, B, and C are sequentially fixed to the top of the gap adjustment slider A, gap adjustment slider B, and lock head locking block. Square sleeves A, B, and C are all fitted onto the outside of the crossbar. The crossbar is fixed to the bottom of the unlocking linkage rod by bolts.

[0007] Furthermore, a limit block is fixedly installed on one side of the middle part of the gap adjusting slider A, the gap adjusting slider B, and the locking block, and a limit groove is opened inside the slider constraint housing to slide and engage with the limit block.

[0008] Furthermore, the top of the hook body is provided with a relief groove for the adaptive rotation of the top of the lock head body.

[0009] Furthermore, the bottom ends of the gap adjusting slider A, the gap adjusting slider B, and the locking block all pass through the hook body and are embedded and connected to the inside of the relief groove.

[0010] Furthermore, a gap of 15mm to 25mm is provided between one side of the bottom of the lock body and the vertical end of the hook body.

[0011] Furthermore, both the bottom ends of the gap adjusting slider A and the bottom ends of the gap adjusting slider B have a 45° slope on the side facing the locking block.

[0012] The beneficial effects of this utility model are as follows: The unlocking linkage rod of this application device works in conjunction with the drone. After the lock body and hook body hook the anchor point, the unlocking linkage rod can be released. The gap adjustment slider and the lock head locking block will adaptively descend and cooperate with the slot of the lock body. At this time, the rotation of the lock body is limited, ensuring that the hook is firm and reliable, avoiding accidental disengagement, and improving safety and convenience. When disengaging, it is only necessary to raise the linkage rod to raise the gap adjustment slider and the lock head locking block. The lock body is no longer limited and can rotate adaptively, thus easily disengaging the device from the anchor point. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0021] like Figure 1-3 As shown, this utility model discloses an adaptive opening and closing locking anchor point hook device for high-altitude operations, including a hook body 4 and an unlocking linkage rod 1. A double boom 5 is fixedly installed on one side of the hook body 4. A lock head body 9 is hinged to the bottom of the double boom 5 through a pin 501. A slot 901 is opened at the top of the lock head body 9. A slider constraint housing 3 is fixedly installed on the top of the hook body 4 by bolts. Inside the slider constraint housing 3, from left to right, a gap adjustment slider A6, a gap adjustment slider B7, and a lock head locking block 8 are sequentially embedded and slidably arranged. The top of the adjusting slider A6, the gap adjusting slider B7, and the locking block 8 are respectively fixed with square sleeves A601, B701, and C801. Square sleeves A601, B701, and C801 are all fitted onto the outside of the crossbar 2. The crossbar 2 is fixed to the bottom of the unlocking linkage rod 1 by bolts. A limit block 11 is fixed on one side of the middle of the gap adjusting slider A6, the gap adjusting slider B7, and the locking block 8. The slider constraint housing 3 has a limit groove 10 that is embedded and slidably engaged with the limit block 11.

[0022] Example 1: Gap adjusting slider A6, gap adjusting slider B7, and lock head locking block 8 all extend from the bottom of the slider constraint housing 3. The limiting block 11 slides within the stroke of the limiting groove 10. That is, when the limiting block 11 reaches the top of the limiting groove 10, the gap adjusting slider A6, gap adjusting slider B7, and lock head locking block 8 cannot continue to rise. The drone hoisting device, that is, the drone is hoisted at the unlocking linkage rod 1, during the hoisting process, the limiting block 11 reaches the top of the limiting groove 10. At this time, the bottom ends of the gap adjusting slider A6, gap adjusting slider B7, and lock head locking block 8 are separated from the slot 901 of the lock head body 9. At this time, the lock head body 9 can adaptively rotate around the pin 501. When the lock head body 9 encounters the anchor rod, the anchor rod can easily pass through the gap between the lock head body 9 and the vertical end of the hook body 4 and enter the inner cavity of the hook body 4. Then, the lock head body 9 rotates clockwise due to its own weight. Figure 1Finally, release the engagement with the unlocking linkage 1. The unlocking linkage 1 descends, and the linkage gap adjusting slider A6, gap adjusting slider B7, and lock head locking block 8 all descend to engage with the slot 901 of the lock head body 9. The gap adjusting slider B7 and lock head locking block 8 are used to hold the anchor rod against one side, reducing the amplitude of left and right swaying. The gap adjusting slider and lock head locking block 8 adaptively descend to engage with the slot 901 of the lock head body 9. At this time, the rotation of the lock head body 9 is restricted. At this time, the hook is firmly engaged with the anchor rod, ensuring that the hook is secure and reliable, avoiding accidental disengagement, and improving safety and convenience. When disengaging, it is only necessary to raise the unlocking linkage 1 to raise the gap adjusting slider and lock head locking block 8. The lock head body 9 is no longer restricted and can rotate adaptively, thus easily disengaging the device from the anchor point.

[0023] In the preferred technical solution, the top of the hook body 4 is provided with a relief groove 401 for adaptive rotation of the top of the lock head body 9. The relief groove 401 is used for adaptive clockwise and counterclockwise rotation of the hook body 4.

[0024] In the preferred technical solution, the bottom ends of the gap adjusting slider A6, the gap adjusting slider B7, and the locking block 8 all pass through the hook body 4 and are embedded and connected to the inside of the relief groove 401. The bottom ends of the gap adjusting slider A6 and the gap adjusting slider B7 are used to abut against one side of the anchor rod to reduce the amplitude of left and right swaying and improve the stability of the fit. The locking block 8 is used to limit the rotation of the hook body 4 to prevent accidental disengagement.

[0025] In the preferred technical solution, a gap of 15mm to 25mm is provided between the bottom end of the lock head body 9 and the vertical end of the hook body 4, and the gap is provided for the insertion of the anchor rod.

[0026] In the preferred technical solution, the bottom ends of the gap adjusting slider A6 and the gap adjusting slider B7 are both provided with a 45° slope on the side facing the locking block 8, which facilitates fitting against the surface of the anchor rod.

[0027] In practical use, the drone hoisting device, i.e., the drone, is hoisted at the unlocking linkage rod 1. During the hoisting process, the limiting block 11 reaches the top of the limiting slide groove 10, and the lock head body 9 can rotate adaptively around the pin shaft 501. Finally, the engagement with the unlocking linkage rod 1 is released, and the unlocking linkage rod 1 descends. The linkage gap adjusting slider A6, the gap adjusting slider B7, and the lock head locking block 8 all descend to engage with the slot 901 of the lock head body 9. The gap adjusting slider B7 and the lock head locking block 8 are used to hold the anchor rod on one side. The gap adjusting slider and the lock head locking block 8 descend adaptively to engage with the slot 901 of the lock head body 9. At this time, the rotation of the lock head body 9 is limited to prevent accidental disengagement. When disengaging, it is only necessary to raise the unlocking linkage rod 1 to raise the gap adjusting slider and the lock head locking block 8. The lock head body 9 loses its limitation and can rotate adaptively, thus easily disengaging the device from the anchor point.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
