TECHNICAL FIELD
[0001] The utility model relates to the technical field of electric power iron tower construction, and specifically relates to a safety rope hook for electric power iron tower construction. BACKGROUND
[0002] During the construction and maintenance of electric power iron towers, workers often need to operate in high-altitude environments. Due to the height and complexity of the structure of electric power iron towers, the safety of construction personnel becomes a primary concern. In traditional high-altitude operations, safety ropes and hooks are important tools to ensure worker safety. However, with the continuous development of the structure and construction technology of electric power iron towers, the existing safety rope hooks have exposed some shortcomings in actual application, which to some extent affect the safety and efficiency of construction.
[0003] Shortcomings of existing safety rope hooks for electric power iron tower construction:
[0004] Insufficient stability of the hook: Many current hook designs have a relatively simple connection structure between the hook blocking arm and the hook body, usually relying on basic mechanical connections or manual locking methods. This design is prone to cause the hook to loosen or fall off due to external forces in actual use, posing a safety hazard. Especially in high-altitude operations, factors such as wind and vibration may cause the hook to fail, threatening worker safety.
[0005] Complexity and inconvenience of operation: The existing safety rope hooks require workers to manually operate multiple steps to complete the opening and locking of the hook during use, which not only increases the complexity of operation, but also prolongs the operation time. In emergency situations, complex operation procedures may affect the worker's response speed and increase the risk.
[0006] Unreliable reset function: Many existing hooks require manual reset after use, lacking an automatic reset mechanism. This design is prone to leave safety hazards when workers forget to reset during actual operation. In addition, the reset function of some hooks relies on relatively simple springs or mechanical structures, which are prone to spring fatigue or mechanical component wear over time, affecting the reset effect and reducing the reliability of the hook.

[0041] Please refer to Figures 1-5 , a specific embodiment of the safety rope hook for power tower construction
[0042] The safety rope hook for power tower construction in the embodiment mainly consists of hook body 1, connecting handle 2, hook blocking arm 3, pressing handle 4, locking assembly 5, reset assembly 7 and spring rotating shaft 8.
[0043] The connection of hook body and hook blocking arm:
[0044] The hook body 1 and the hook blocking arm 3 are connected through the spring rotating shaft 8. The spring rotating shaft 8 has a certain elasticity, so that the hook blocking arm 3 can be automatically closed after being manually opened, thereby forming a closed ring. When the hook blocking arm 3 is not subjected to external force, the end of the hook blocking arm 3 will tightly fit in the inner side notch at the end of the hook body 1 under the elastic action of the spring rotating shaft 8, forming a closed hook structure to prevent the safety rope from falling out of the hook.
[0045] The notch shape provided at the inner side of the end of the hook body 1 is matched with the end of the hook blocking arm 3, ensuring that the hook blocking arm 3 can tightly cooperate with the hook body 1 when closed, improving the safety and reliability of the hook.
[0046] The structure and arrangement of the connecting handle:
[0047] The connecting handle 2 is butt-jointed to the lower end of the hook body 1, and an installation perforation 21 is arranged inside along the length direction. The installation perforation 21 is used for installing the reset component 7.
[0048] A locking hole 22 is provided on the front surface of the connecting handle 2 close to the lower end, and the diameter of the locking hole 22 is matched with the diameter of the locking screw 54, which is used for enabling the inner side end of the locking screw 54 to be screwed into the locking hole 22 when the locking assembly 5 is unlocked by sliding the pressing handle 4, thereby realizing the position fixation of the locking assembly 5.
[0049] Connection and action of the pressing handle:
[0050] The pressing handle 4 is connected to the bottom end of the hook blocking arm 3. The pressing handle 4 is a long strip structure, and the operator can press the pressing handle 4 to open the hook blocking arm 3 against the elastic force of the spring rotating shaft 8, thereby facilitating the hooking of the safety rope on the corresponding position of the power iron tower. When the pressing handle 4 is released, the hook blocking arm 3 will be automatically reset under the action of the spring rotating shaft 8 to close the hook opening.
[0051] Structure and function of the locking assembly:
[0052] The locking assembly 5 includes a first sleeve 51 which is slidably sleeved on the connecting handle 2, and the inner diameter of the first sleeve 51 is slightly larger than the outer diameter of the connecting handle 2, so that the first sleeve 51 can smoothly slide up and down on the connecting handle 2. The first sleeve 51 is butt-jointed to the reset driving end of the reset component 7 in the installation perforation 21, and when the reset component 7 works, the first sleeve 51 can be pushed to slide upward.
[0053] It also includes a second sleeve 52 which is slidably sleeved on the pressing handle 4, and the inner diameter of the second sleeve 52 is slightly larger than the outer diameter of the pressing handle 4, so that the second sleeve 52 can freely slide on the pressing handle 4.
[0054] The connecting rib plate 53 connecting the first sleeve 51 and the second sleeve 52 is in a flat plate structure and plays a role in connection and force transmission. When the first sleeve 51 slides up and down, the second sleeve 52 is driven to move synchronously through the connecting rib plate 53.
[0055] The locking screw 54 abutting the front of the first sleeve 51 is in an external thread structure. By rotating the locking screw 54, the inner end thereof can be screwed into the locking hole 22 when the locking assembly 5 slides down to unlock the pressing handle 4, so as to fix the locking assembly 5 at the unlocking position, facilitating the operator to hang the safety rope hook on the power iron tower. When it is needed to lock the pressing handle 4, the locking screw 54 is only needed to be screwed out of the locking hole 22. Under the action of the reset assembly 7, the locking assembly 5 will slide up, so that the pressing handle 4 is in the locked state and the hook blocking arm 3 cannot be opened, ensuring the safe use of the safety rope hook.
[0056] The structure and action of the reset assembly:
[0057] The reset assembly 7 is installed inside the installation through hole 21 and includes a guide column 71 installed inside the installation through hole 21. The guide column 71 is in a cylindrical structure and is fixed at the upper and lower ends of the installation through hole 21, providing a guiding action for the up and down sliding of the guide sleeve 72.
[0058] The guide sleeve 72 slidingly sleeved on the guide column 71 is in a cylindrical structure and has an inner diameter slightly larger than the outer diameter of the guide column 71, so that the guide sleeve 72 can smoothly slide up and down on the guide column 71. The outer wall of the guide sleeve 72 is in abutment with the inner wall of the first sleeve 51, and when the guide sleeve 72 slides up and down on the guide column 71, the first sleeve 51 will be driven to move synchronously.
[0059] The reset spring 73 sleeved at the lower end of the guide column 71 is a compression spring, and the top end thereof is connected to the bottom end of the guide sleeve 72. When the locking assembly 5 slides down to unlock the pressing handle 4, the reset spring 73 is compressed to store elastic potential energy. After the unlocking operation is completed, under the elastic force of the reset spring 73, the guide sleeve 72 will slide up along the guide column 71, thereby driving the locking assembly 5 to move upward, and further driving the second sleeve 52 to slidingly sleeve the pressing handle 4 to perform the locking operation.
[0060] Other components and settings:
[0061] The length of the connecting handle 2 is set to be 2 times the length of the pressing handle 4. This length ratio design can not only ensure that the operator has enough operation space when operating the pressing handle 4, but also can provide enough space inside the connecting handle 2 to install the reset assembly 7 and the locking assembly 5.
[0062] The bottom end of the connecting handle 2 is provided with a rope which is tied to the operator, one end of the rope is fixed to the bottom end of the connecting handle 2, and the other end is tied to the operator by a safety belt or the like, so as to ensure the safety of the operator during high-altitude operation. When the operator accidentally falls, the safety rope hook can suspend the operator on the power tower through the rope, so as to avoid falling accidents.
[0063] The end faces of the hook body 1 and the hook blocking arm 3 which are in contact with the safety rope are polished into round corners, so as to reduce the wear of the safety rope during use and prolong the service life of the safety rope. Meanwhile, the round corner design can also avoid the jamming of the safety rope in the hook, so as to ensure the smooth entry and exit of the safety rope in the hook.
[0064] Use process:
[0065] Preparation: tie the rope at the bottom end of the connecting handle 2 to the operator to ensure safety.
[0066] Open the hook: press the pressing handle 4 to open the hook blocking arm 3 against the elastic force of the spring shaft 8.
[0067] Hang the hook: hang the opened hook on the corresponding position of the power tower.
[0068] Loosen the pressing handle: after loosening the pressing handle 4, the hook blocking arm 3 is automatically reset under the action of the spring shaft 8, the hook opening is closed, and the pressing handle 4 returns to the initial position.
[0069] Lock the hook: rotate the locking screw 54 to disengage from the locking hole 22, at this time, the sliding locking assembly 5 slides upward along the guide sleeve 72 under the influence of the reset spring 73, at this time, the second sleeve 52 is automatically sleeved on the pressing handle 4, the pressing handle 4 is locked, and it is ensured that the hook blocking arm 3 cannot be opened.
