Technical Field
[0001] This invention relates to the field of electrical safety equipment technology, and more specifically, to a climbing rope bottom fixing device and fixing method. Background Technology
[0002] Climbing power transmission towers is often necessary during tower erection, line stringing, maintenance, and defect elimination operations. Climbing ropes (steel wire ropes) are typically used for ascending and descending towers. After the top and bottom of the climbing rope are secured, workers use self-locking devices to attach themselves to the rope and perform the work.
[0003] During the tower erection process, the tower height gradually increases, and the length of the climbing rope needs to be adjusted accordingly. If the climbing rope is not securely fixed, the safety of the workers cannot be guaranteed. Therefore, a bottom fixing device and method for the climbing rope is needed, which can flexibly and stably adjust the length of the climbing rope to solve the above problem. Summary of the Invention

Detailed Implementation
[0017] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the invention. Example
[0018] like Figure 1-3 As shown, this embodiment provides a climbing rope bottom fixing device, which includes a clamp 110 for clamping onto the tower foot plate of the iron tower. One end of a mounting plate 120 is connected to the clamp 110, and the other end of the mounting plate 120 is connected to a bent rope clamping plate 130. One end of the rope clamping plate 130 is hinged to a cover plate 140, which can be attached to the mounting plate 120. The cooperation between the cover plate 140 and the rope clamping plate 130 can clamp the climbing rope. The cover plate 140 is provided with a square hole 141. The mounting plate 120 has a through hole, and a movable round rod 150 is provided in the through hole. One end of the round rod 150 is connected to a square strip 160, which can fit into a square hole 141. The other end of the round rod 150 is connected to a block 170. Both sides of the block 170 are provided with long strips 180, and one end of the two long strips 180 is connected to a lever 190.
[0019] The entire fixing device is secured to the tower base plate via clamp 110, ensuring stable installation of the climbing rope. The bent rope clamping plate 130 and cover plate 140 work together to hold the climbing rope, securing its base. Lever 190 rotates the long bar 180. Since adjacent sides of the long bar 180 are of different lengths, rotating it causes its longer side to press against the mounting plate 120, pulling the round rod 150 and square bar 160. Tightening the square bar 160 causes the cover plate 140 to adhere to the mounting plate 120, allowing the cover plate 140 and rope clamping plate 130 to secure the climbing rope. The square bar 160 passes through the square hole 141. Rotating the square bar 160 pulls the cover plate 140, while rotating it releases it. This allows for easy and convenient operation of the cover plate 140. Furthermore, the arrangement of the square bar 160 and the square block 170 can prevent the round rod 150 from falling out of the through hole.
[0020] This fixing device can easily secure the bottom of the climbing rope and also easily loosen it, allowing for convenient adjustment of the climbing rope's clamping position. The installation and removal of the bottom of the climbing rope are also very convenient, making it very suitable for tower erection, as well as tower maintenance and defect repair operations.
[0021] The chuck 110 includes two parallel clamping plates 111, and a connecting plate 112 is connected to the same end of the two clamping plates 111. A clamping cavity 113 is formed between the connecting plate 112 and the two clamping plates 111. A screw 114 is threaded through a clamping plate 111. A handwheel 115 is provided at one end of the screw 114, and a support block 116 is provided at the other end. The support block 116 is located inside the clamping cavity 113. Another clamping plate 111 is perpendicularly connected to the mounting plate 120.
[0022] The cavity 113 formed between the connecting plate 112 and the two clamping plates 111 can be fitted onto the tower foot plate. The handwheel 115 rotates the screw 114, causing the support block 116 to abut against the tower foot plate, so that the clamp 110 can be installed on the tower foot plate.
[0023] The rope clamping plate 130 has two collars 131 on both sides at one end, and the cover plate 140 has a shaft 141 at one end, which can be rotatably inserted into the collar 131.
[0024] The collar 131 and the shaft 141 allow the cover plate 140 to rotate easily.
[0025] When lever 190 is perpendicular to mounting plate 120, the long surface of strip 160 is parallel to the corresponding surface of mounting plate 120; when lever 190 is parallel to mounting plate 120, the long surface of strip 160 is perpendicular to the corresponding surface of mounting plate 120. This arrangement is intended to ensure that when lever 190 is perpendicular to mounting plate 120, strip 160 is in a relaxed state; when lever 190 is parallel to mounting plate 120, strip 160 is in a tensioned state. Since the tensioned state lasts longer, having lever 190 parallel to mounting plate 120 reduces space requirements and improves safety.
[0026] The other end of the strip 160 is rounded, which allows the strip 160 to rotate easily.
[0027] The lever 190 is a threaded lever, and the lever 190 is threadedly connected to the sleeve 191; The other clamping plate 111 is provided with a round block 117, and a round groove 118 is provided in the round block 117, so that the rod head of the sleeve rod 191 can be inserted into the round groove 118.
[0028] When the lever 190 is parallel to the mounting plate 120, the climbing rope is clamped. However, the stability of the lever 190 is insufficient at this time. Therefore, the stability of the lever 190 is improved by the cooperation between the sleeve 191 and the circular groove 118. Moreover, this design can also improve the stability of the mounting plate 120 and prevent the mounting plate 120 from deforming.
[0029] A fastening nut is fitted onto the lever 190 and the screw 114 respectively.
[0030] Tightening the nut improves the stability of the lever 190 and the screw 114.
[0031] This embodiment provides a method for securing the bottom of a climbing rope, which employs the aforementioned climbing rope bottom securing device and includes the following steps: 1. Clamp the 110 clamp onto the base plate of the iron tower; Place the clamp 110 onto the tower foot plate, and then rotate the screw 114 to make the support block 116 abut against the tower foot plate.
[0032] 2. Rotate the round rod 150 to pass the square bar 160 through the square hole 141, and then rotate the round rod 150 back so that the square hole 141 locks the square bar 160. 3. Pass the climbing rope through the gap between the rope clamping plate 130 and the mounting plate 120; Fourth, straighten the climbing rope and pull the lever 190 so that the short side of the long bar 180 abuts against the mounting plate 120. At this time, the round bar 150 is pulled and the square bar 160 tightly pulls the cover plate 140, and the climbing rope is clamped, thus achieving the bottom fixation of the climbing rope.
[0033] The lever 190 needs to be turned 90°. At this time, the lever 190 corresponds to the circular groove 118. Rotate the sleeve 191 so that the sleeve 191 extends into the circular groove 118 and is fixed by the fastening nut.
[0034] This method allows for a convenient, quick, and stable fixation of the bottom of the climbing rope to the tower base plate, and also makes it easy to loosen the climbing rope, facilitating length adjustment or maintenance and replacement.
[0035] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
