[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0042] Specific Implementation Example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, a temporary fall arrest rope arrangement device for transmission towers includes a climbing frame 1, a drive belt 2, and a drive motor. The climbing frame 1 includes a connecting plate 1.2 and two climbing guides 1.1 on the left and right sides. In this embodiment, there are two connecting plates, one above the other. The two climbing guides are connected to the connecting plate by bolts, and the climbing guides and the connecting plate can be detached. Each of the two climbing guides is provided with a vertical groove 1.4, which extends vertically and is open at both ends. The groove openings of the vertical grooves on the two climbing guides face each other. The vertical grooves are matched with the foot spikes 6.1 on the transmission tower. The length of the vertical groove is greater than the distance between two adjacent foot spikes on the foot spike steel pipe pole. In this embodiment, the length of the vertical groove is 2-3 times the distance between two adjacent foot spikes on the foot spike steel pipe pole (in this text, two adjacent foot spikes on the foot spike steel pipe pole refer to two adjacent foot spikes located on the same side of the foot spike steel pipe pole).

[0043] The drive belt 2 is a drive belt or drive chain. The drive belt is mounted on the climbing frame and located between two climbing guides. The drive belt is vertically distributed. Several climbing poles 2.1 that engage with foot spikes are provided on the drive belt. In this embodiment, there are two drive belts, and the two drive belts are distributed in parallel.

[0044] The drive motor is mounted on the climbing frame and drives the drive belts. In this embodiment, both drive belts are driven by the same drive motor to ensure synchronous movement. Of course, each drive belt can also be driven by its own drive motor.

[0045] The specific use of the temporary fall arrest rope arrangement device for power transmission towers in this embodiment is as follows.

[0046] Connect one end of the temporary fall arrest rope 7 to the climbing frame;

[0047] Insert the left side portion of the foot nails 6.1 into the vertical groove 1.4 on the left side of the climbing guide; insert the right side portion of the foot nails 6.1 into the vertical groove 1.4 on the right side of the climbing guide (in actual operation, after the vertical groove of the climbing guide is properly engaged with the foot nails, the two climbing guides are connected as one unit through the connecting plate). In this way, the foot nails distributed sequentially from top to bottom on both sides of the power transmission steel pipe pole act as climbing guides and engage with the vertical grooves, ensuring that the climbing frame will not tilt to the left or right or forward or backward during the up and down movement along the foot nail steel pipe pole.

[0048] Then, the driving motor drives the driving belt, and through the cooperation of the climbing rod on the driving belt and the foot nail, the climbing frame is driven to climb up along the foot nail steel pipe pole until the climbing frame climbs up to the specified position, and the temporary anti-falling rope is arranged to the specified height, realizing the automatic up-pole arrangement of the temporary anti-falling rope. In this way, the temporary anti-falling rope is arranged, and the first tower worker has safety protection, thereby effectively solving the problem that the first worker who hangs the temporary anti-falling rope on the pole has no safety protection measures and has a high-altitude falling safety hazard. When the first worker climbs to the position of the climbing frame, the anti-falling rope is rearranged, and the anti-falling rope is fixed at the specified position of the power transmission steel pipe pole, thereby completing the arrangement of the anti-falling rope. Thereafter, the power transmission tower temporary anti-falling rope arrangement device can drive the driving belt to move in the reverse direction through the driving motor, and through the cooperation of the climbing rod on the driving belt and the foot nail, the climbing frame is driven to climb down along the foot nail steel pipe pole.

[0049] Further, the power transmission tower temporary anti-falling rope arrangement device further comprises a guide wheel 3. The guide wheel cooperates with the foot nail steel pipe pole of the power transmission tower, and the outer peripheral surface of the guide wheel is a circular arc surface. The guide wheel is one or more, and the multiple guide wheels are sequentially distributed from top to bottom. In the embodiment, the guide wheel is two, and the guide wheel is located on the centerline of symmetry of the two climbing guide pieces. In this way, during the process of climbing the climbing frame along the foot nail steel pipe pole upward, the guide wheel can be abutted against the foot nail steel pipe pole to limit the climbing frame, thereby further improving the stability of the climbing frame climbing along the foot nail steel pipe pole upward.

[0050] Further, the guide opening 1.3 is arranged at the upper and lower ends of the vertical sliding groove 1.4. The opening width of the guide opening at the upper end of the vertical sliding groove gradually increases from bottom to top. The opening width of the guide opening at the lower end of the vertical sliding groove gradually increases from top to bottom. In this way, during the process of climbing the climbing frame along the foot nail steel pipe pole upward or downward, it is ensured that the foot nail can smoothly enter the vertical sliding groove.

[0051] Further, the lower part of the climbing frame is provided with a temporary anti-falling rope hanging ring 5. In this way, one end of the temporary anti-falling rope can be hung on the temporary anti-falling rope hanging ring.

[0052] In the embodiment, the remaining structures are referred to the specific embodiment one, and the difference is that,

[0053] As shown in Figure 1 , Figure 2 、 Figure 3 , a power transmission tower temporary anti-falling rope arrangement device further comprises a climbing height locking mechanism 4. In the embodiment, the climbing height locking mechanism corresponds to the climbing guide piece one by one. The climbing height locking mechanism 4 comprises a guide part, a locking support 4.1, a guide ring 4.4 and a height fixing rope 4.8.

[0054] The guide component is arranged on the corresponding climbing guide, and specifically, the guide component comprises a guide sleeve 4.5 arranged on the corresponding climbing guide and a guide rod 4.6 sliding along the guide sleeve. The guide rod is parallel to the spud. One end of the guide rod is connected with the locking support, and the other end of the guide rod is provided with a stopper 4.7. The guide sleeve is located between the stopper and the locking support.

[0055] The locking support moves along the guide component, and the direction in which the locking support moves along the guide component is parallel to the spud. The bottom wall of the vertical sliding groove is provided with a locking plate passing opening, that is, the bottom wall of the vertical sliding groove is provided with the locking plate passing opening opposite to the slot of the vertical sliding groove. The locking plate passing opening is in a strip shape, and the length direction of the locking plate passing opening extends upward and downward.

[0056] The locking support 4.1 comprises a vertical locking plate 4.2 located in the locking plate passing opening and at least one spud locking hole 4.3 arranged on the vertical locking plate. The vertical locking plate is vertically distributed. The vertical locking plate is perpendicular to the spud. When the stopper abuts against the guide sleeve, the side surface of the vertical locking plate facing the slot of the vertical sliding groove is flush with the surface of the bottom wall of the vertical sliding groove.

[0057] The length of the vertical locking plate is greater than the interval between two adjacent spuds, and in the embodiment, the length of the vertical locking plate is 2.1-2.6 times the interval between two adjacent spuds. The vertical locking plate is provided with two spud locking holes upward and downward, and the interval between the two spud locking holes is the same as the interval between two adjacent spuds.

[0058] The guide ring 4.4 is arranged on the corresponding climbing guide.

[0059] The height fixing rope 4.8 passes through the guide ring. One end of the height fixing rope is connected with the locking support, and the other end of the height fixing rope is connected with the counterweight 4.9.

[0060] Although the driving belt can drive the climbing frame to climb upward along the spud steel pipe rod and arrange the temporary anti-falling rope to the specified height by driving the climbing rod on the driving belt to cooperate with the spud, the climbing frame cannot be reliably fixed at the specified height position by only cooperating the climbing rod with the spud after the climbing frame climbs upward to the specified height. In order to solve this problem, the climbing height fixing locking mechanism is specially arranged in the scheme, and specifically,

[0061] Before the climbing frame climbs upward along the spud steel pipe rod, the locking support is moved until the stopper abuts against the guide sleeve. At this time, the side surface of the vertical locking plate facing the slot of the vertical sliding groove is flush with the surface of the bottom wall of the vertical sliding groove, so as not to affect the climbing of the climbing frame along the spud steel pipe rod upward.

[0062] After the climbing frame is climbed to the specified height along the foot nail steel pipe pole, the height fixing rope is straightened, at this time, under the action of the counterweight, the vertical locking plate of the locking support is moved to the direction of the slot of the vertical sliding groove, at this time, if the foot nail is aligned with the foot nail locking hole, the foot nail will be inserted into the foot nail locking hole, thereby stably and reliably locking the climbing frame at the specified height position; if the foot nail is misaligned with the foot nail locking hole, the vertical locking plate will be abutted against the end of the foot nail, and then the climbing frame drives the vertical locking plate to continue to climb upward along the foot nail steel pipe pole until the foot nail is aligned with the foot nail locking hole, when the foot nail is aligned with the foot nail locking hole, under the action of the counterweight, the foot nail will be inserted into the foot nail locking hole, thereby stably and reliably locking the climbing frame at the specified height position. In this way, not only the climbing frame can be stably and reliably locked at the specified height position, but also the length of the height fixing rope can be set according to actual needs to limit the specified height position of the climbing frame climbing upward, so as to adapt to different climbing height needs. At the same time, the problems that the height position of the climbing frame climbing upward is not in place or the height position of the climbing frame is too high to collide with the overhead cable, causing damage to the overhead cable, etc. can be avoided.

[0063] More importantly, compared with the locking device in the prior art, after the climbing frame is climbed to the specified height position, the locking device needs to be manually controlled to lock the climbing frame, and the operator may forget to control the locking device to lock the climbing frame due to negligence; the climbing height locking mechanism of the present scheme can automatically lock the climbing frame at the specified height position after the climbing frame is climbed to the specified height along the foot nail steel pipe pole, thereby effectively solving the problem that the locking device in the prior art needs to be manually controlled to lock the climbing frame, and the operator may forget to control the locking device to lock the climbing frame due to negligence.

[0064] When the first worker arrives at the position of the climbing frame, the fall arrest rope is rearranged and fixed at the specified position of the power transmission steel pipe pole. Then, the locking support is moved until the stop block abuts against the guide sleeve; at this time, the side surface of the vertical locking plate facing the slot of the vertical sliding groove is flush with the bottom wall surface of the vertical sliding groove, and the foot nail is separated from the foot nail locking hole. Then, the power transmission tower temporary fall arrest rope arrangement device can drive the driving motor to drive the driving belt to move reversely, and the climbing frame is driven to climb downward along the foot nail steel pipe pole through the cooperation of the climbing rod on the driving belt and the foot nail.

[0065] The above is only a preferred embodiment of the present application, and does not limit the present application, any simple modification, change and equivalent transformation of the above embodiment according to the technical essence of the present application are still within the protection scope of the technical solution of the present application.
