The locking pin 6 is arranged in the limiting groove 8 and the two ends of the locking pin 6 pass through the fixed body and the movable body 1 respectively; the locking arm 9 is rotatably installed on the fixed body, one end of the locking arm 9 can abut against the flexible guide rail 10, and the other end of the locking arm 9 extends out of the fixed body for connecting the safety belt.

[0034] Among them, the fixed body and the movable body 1 form the installation body part of the self-locking device, and the fixed body and the movable body 1 are interlocked with each other by adopting an inlaid convex and concave positioning structure, and an installation groove 11 for accommodating the flexible guide rail 10 is left between the fixed body and the movable body 1, so that the self-locking device can be sleeved on the flexible guide rail 10, which is convenient for the operator to drive the self-locking device to move on the flexible guide rail 10. At the same time, the interlocking assembly structure is easy to install and form, and has a compact structure, good structural mechanical properties and low cost. It is preferred that the installation body part of the self-locking device is made of high-strength aluminum alloy, which is easy to form and install.

[0035] Specifically, Figure 1-2 As shown, in order to improve the installation stability of the fixed body and the movable body 1, in this embodiment, the fixed body includes an intermediate insert 2 and a base, and the intermediate insert 2 is embedded between the movable body 1 and the base. The movable body 1 can be slidably set on the intermediate insert 2, which is convenient for adjusting the opening and closing of the installation groove 11 for accommodating the flexible guide rail 10, and it is convenient for the anti-fall self-locking device to be disassembled and assembled on the flexible guide rail 10. At the same time, the base, the intermediate insert 2 and the movable body 1 are respectively embedded and detachably connected, which is easy to repair and replace.

[0036] Among them, for the structural design of the intermediate insert 2, in order to improve the structural strength of the intermediate insert 2 and facilitate connection with the base and the movable body 1, in this embodiment, the intermediate insert 2 includes a first mounting portion 210 and a second mounting portion 220, and two spaced connecting portions 230 are preferably arranged between the first mounting portion 210 and the second mounting portion 220, so that the intermediate insert 2 forms an approximately H-shaped structure through the two mounting portions and the two connecting portions 230. At the same time, it is preferred that the first mounting portion 210 is shorter than the second mounting portion 220, and the two connecting portions 230 are respectively spaced apart from the two ends of the first mounting portion 210, that is, it is conducive to forming a first recess 240 between the first mounting portion 210 and each connecting portion 230, which is convenient for fitting and installing with the movable body 1, and two parallel grooves are provided on the end surface of the second mounting portion 220 facing the base to form a second recess 250 for fitting and installing with the base, thereby, a convex-concave combination structure of three components of the movable body 1, the intermediate insert 2 and the base is formed in sequence, forming the installation body part in which the self-locking device is sleeved on the flexible guide rail 10.

[0037] As for the structural design of the movable body 1, the present embodiment preferably designs the movable body 1 as a C-shaped structure, that is, first convex portions extending inward are provided at both ends of the movable body 1 for engaging with the first concave portions 240 at both ends of the middle insert 2. At the same time, the C-shaped structure facilitates the sliding of the movable body 1 along the middle insert 2 to adjust the opening and closing of the mounting groove 11, thereby preventing the movable body 1 from falling off.

[0038] As for the structural design of the base, the present embodiment preferably provides the base with a fitting portion and a bending portion, wherein the fitting portion is provided with two parallel ribs for fitting with the second recess 250 on the middle insert 2, and at the same time, the bending portion is arranged on one side of the fitting portion, and the bending portion is used to accommodate the flexible guide rail 10, and at the same time, the opening end of the bending portion is covered with the movable body 1 to form a mounting groove 11 for accommodating the flexible guide rail 10, that is, when the movable body 1 slides laterally along the middle insert 2, the opening end of the bending portion is exposed, which is equivalent to the mounting groove 11 being in an open state, so that the self-locking device can be installed from the opening. After being installed on the flexible guide rail 10, when the movable main body 1 is reset along the middle insert 2, the open end of the bent portion is covered, which is equivalent to the mounting groove 11 being in a closed state, so that the connection and locking between the self-locking device and the flexible guide rail 10 can be realized, that is, the self-locking device can move along the flexible guide rail 10 with the action of the operator. Among them, in this embodiment, the bent portion is preferably set to an arc structure, which is conducive to fitting the structure of the flexible guide rail 10. At the same time, arc-shaped transition sections are respectively set at the end of the movable main body 1 close to the mounting groove 11 and the end of the middle insert 2 close to the mounting groove 11, which are used to fit the structure of the flexible guide rail 10.

[0039] In addition, in order to facilitate the installation of the locking arm 9, the present embodiment preferably forms a cavity between the two connecting parts 230 of the middle insert 2 for accommodating the locking arm 9, so that one end of the locking arm 9 can extend into the installation groove 11 and abut against the flexible guide rail 10, and the other end of the locking arm 9 can extend out for connecting to the safety belt worn by the operator.

[0040] Furthermore, if Figure 1-6 As shown, in this embodiment, in order to prevent the anti-fool mechanism on the self-locking device from being accidentally triggered, thereby preventing the self-locking device from falling off the flexible guide rail 10 and reducing the occurrence of falling accidents, in this embodiment, it is preferred to set the anti-fool mechanism of the present invention to be hidden, that is, the anti-fool mechanism includes a sliding seat 4, a reset spring 5 and a locking pin 6, and a sliding groove 7 is provided on the wall surface of the fixed body facing the movable body 1, the sliding seat 4 slides along the sliding groove 7, and the two ends of the reset spring 5 are respectively arranged between the sliding groove 7 and the sliding seat 4, and a limiting groove 8 is provided on the sliding seat 4. The locking pin 6 is arranged in the limiting groove 8 and the two ends of the locking pin 6 pass through the fixed body and the movable body 1 respectively.

[0041] Specifically, in the present embodiment, the slide groove 7 for installing the sliding seat 4 is preferably arranged on the end surface of the middle insert 2 facing the base, and the bottom end opening of the slide groove 7 is preferably extended to the bottom surface of the middle insert 2, and the top end opening of the slide groove 7 is set as a closed end. At this time, the return spring 5 can be arranged between the closed end of the slide groove 7 and the top end of the sliding seat 4, and the locking pin 6 can pass through the limiting groove 8 on the sliding seat 4 and penetrate the movable body 1, the middle insert 2 and the base, thereby limiting the sliding of the movable body 1 along the middle insert 2.

[0042] Furthermore, a limiting section is provided on the locking pin 6, and the diameter of the limiting section is smaller than the diameter of the two end portions of the locking pin 6. The limiting groove 8 is provided with a small diameter end and a large diameter end. The small diameter end is used to cooperate with the limiting section of the locking pin 6 to limit the movement of the locking pin 6, and the large diameter end is used to release the movement restriction of the locking pin 6.

[0043] At the same time, with regard to the structural design of the locking pin 6, in this embodiment, it is preferred that a limiting section is provided on the locking pin 6, and the diameter of the limiting section is smaller than the diameter of the two end portions of the locking pin 6. Correspondingly, the limiting groove 8 is provided with a small diameter end and a large diameter end. It is preferred that the limiting groove 8 is provided with a special waist shape, and the small diameter end is used to cooperate with the limiting section of the locking pin 6 to limit the movement of the locking pin 6, and the large diameter end is used to release the movement restriction of the locking pin 6, that is, when the anti-foolproof mechanism is not opened, the limiting section of the locking pin 6 is at the small diameter end of the limiting groove 8, thereby limiting the axial movement of the locking pin 6. The movable body 1 is restricted from sliding along the middle insert 2, so that the opening of the mounting groove 11 is in a closed state, that is, the self-locking device is prevented from falling off the flexible guide rail 10. When the anti-foolproof mechanism is turned on, the limiting section of the locking pin 6 is at the large diameter end of the limiting groove 8. Since the locking pin 6 can move axially at the large diameter end of the limiting groove 8, the locking pin 6 can be separated from the movable body 1, thereby releasing the restriction on the movement of the movable body 1 along the middle insert 2, so that the opening of the mounting groove 11 can be opened, which is convenient for the disassembly and assembly of the self-locking device and the flexible guide rail 10.

[0044] Specifically, Figure 3-6 As shown, regarding the opening and closing of the foolproof mechanism, this embodiment is mainly realized by pushing the sliding seat 4 to move in the sliding groove 7, that is, the return spring 5 makes the sliding seat 4 located at the bottom opening of the sliding groove 7 in a natural state, and at this time, the limiting section of the locking pin 6 is at the small diameter end of the limiting groove 8, and the locking pin 6 runs through the movable body 1, the middle insert 2 and the base, restricting the self-locking device from detaching from the flexible guide rail 10, but when an external force pushes the sliding seat 4 to move upward along the sliding groove 7, as the sliding seat 4 moves, the limiting groove 8 of the sliding seat 4 also moves, thereby making the limiting Relative movement occurs between the limiting groove 8 and the locking pin 6, so that the locking pin 6 moves from the small diameter end of the limiting groove 8 to the large diameter end, thereby releasing the axial movement restriction of the limiting groove 8 on the locking pin 6, so that the locking pin 6 can be separated from the movable body 1, which is beneficial for the movable body 1 to move along the middle insert 2, thereby realizing the disassembly and assembly of the self-locking device and the flexible guide rail 10, and when the sliding seat 4 moves upward, the return spring 5 is compressed. Therefore, when the sliding seat 4 is no longer subjected to external force, the sliding seat 4 can be reset to the bottom opening of the sliding groove 7 by relying on the return spring 5, which is convenient for the next operation.

[0045] Furthermore, in order to facilitate the operator to apply external force to the sliding seat 4, in this embodiment, a striker 20 is preferably installed on the bottom fixed bracket of the flexible guide rail 10 for installing the transmission tower, that is, the striker 20 is inserted into the opening of the slide groove 7 at the bottom end of the middle insert 2, so that the sliding seat 4 can be pushed to move along the slide groove 7, so that the self-locking device and the flexible guide rail 10 can be disassembled. When the striker 20 is pulled out, the self-locking device and the flexible guide rail 10 can be locked to prevent the self-locking device from detaching. That is, when the operator is working at high altitude, the bottom striker 20 is inserted into the self-locking device at the bottom of the tower to open the self-locking device mounting groove 11, and the self-locking device is installed on the flexible guide rail 10. After pulling out the striker 20, it is only necessary to manually push the movable body 1 to reset, and manually push the locking pin 6 to reset and penetrate the movable body 1 to complete the closing of the mounting groove 11 of the self-locking device. , so that the self-locking device is stably connected to the flexible guide rail 10 and enters a normal working state. Only after the operation is completed and the operator returns to the bottom of the tower, the self-locking device can be opened by manually inserting the striker 20 into the self-locking device and the self-locking device can be removed from the flexible guide rail 10, thereby realizing the hidden installation and opening and closing of the anti-fool mechanism, so that the self-locking device has a one-way closing function, that is, after the self-locking device is installed in the flexible guide rail 10, it only needs to manually push the movable body 1 and the locking pin 6 to reset, so that the self-locking device can return to the closed self-locking state. Due to the one-way sliding restriction of the locking pin 6 and the limit groove 8, once the locking pin 6 is reset, the self-locking device will not be separated from the flexible guide rail 10 due to accidental touch or collision of the shell, and it can only be opened by the striker 20 at the bottom of the tower, which effectively prevents accidental touch during use and improves operation safety.

[0046] Furthermore, in order to facilitate the stable sliding of the sliding seat 4, in this embodiment, corresponding mounting holes are provided on the first mounting portion 210 and the second mounting portion 220 of the middle insert 2, and a guide shaft 12 is provided in the mounting hole, and a guide groove is provided on the guide shaft 12. The sliding seat 4 passes through the guide groove. The interior of the guide shaft 12 is hollow, and the locking pin 6 is inserted in the guide shaft 12. That is, the guide groove on the guide shaft 12 is used to further limit the movement of the sliding seat 4 to avoid movement deviation. At the same time, the guide shaft 12 is used to position the locking pin 6 to facilitate the axial movement of the locking pin 6 to prevent movement deviation.

[0047] Correspondingly, in order to enable the locking pin 6 to penetrate the movable body 1 , the middle insert 2 and the base, in this embodiment, a stepped fixing hole is provided on the movable base for installing the locking pin 6 .

[0048] Furthermore, in order to facilitate the movement of the movable body 1 along the middle insert 2, it is preferred to set a movable groove 14 on the movable body 1, and a sliding pin 15 is provided on the middle insert 2. The sliding pin 15 is set in the movable groove 14. The length of the movable groove 14 is set to limit the opening and closing degree of the mounting groove 11 on the self-locking device, that is, the lateral movement of the movable body 1 along the middle insert 2 is limited to prevent the movable body 1 from falling off the middle insert 2.

[0049] Furthermore, in this embodiment, in order to facilitate the installation of the return spring 5, a first spring groove can be set on the side wall of the slide groove 7, and a second spring groove can be set on the sliding seat 4, the return spring 5 is placed in the first spring groove and the second spring groove at the same time, and a collision part 21 is set at the bottom of the sliding seat 4 to increase the contact area between the striker 20 and the sliding part.

[0050] Further, regarding the structural design of the locking arm 9, as shown in FIG. Figure 7-8 As shown, in this embodiment, a first mounting ring 910 is provided on the locking arm 9, and the first mounting ring 910 is rotatably installed on the outer wall of the guide shaft 12. The first mounting ring 910 is colinear with the axis of the guide shaft 12 and the locking pin 6. A second mounting ring 920 is provided at the end of the locking arm 9 for connecting the safety belt, and a connecting buckle 13 is provided in the second mounting ring 920 for locking with the safety belt of the operator.

[0051] Specifically, in the present embodiment, the locking arm 9 can rotate around the guide shaft 12. When the operator falls, the safety belt applies force to the second mounting ring 920 end of the locking arm 9 through the connecting lock buckle 13, so that the end of the locking arm 9 connected to the safety belt moves downward, and then the locking arm 9 rotates around the guide shaft 12, causing the other end of the locking arm 9 to move upward and abut against the flexible guide rail 10 in the mounting groove 11 and get stuck, thereby limiting the movement of the self-locking device on the flexible guide rail 10 to achieve the purpose of instantaneous falling prevention, that is, the self-locking device is affected by the gravity of falling, and the connecting lock buckle 13 drives the locking arm 9 to rotate a certain angle. When it rotates to the point where the locking arm 9 contacts the flexible guide rail 10, the locking arm 9 stops rotating and abuts against the flexible guide rail 10 to achieve self-locking falling prevention.

[0052] Furthermore, in order to increase the contact area between the locking arm 9 and the flexible guide rail 10, in this embodiment, a locking pressure block 18 is preferably provided on the broken arm of the locking arm 9 to improve the abutting and pressing effect.

[0053] Furthermore, if Figure 2 As shown, in order to prevent the locking arm 9 from pressing the guide rail to restrict the movement of the operator during normal operation, in this embodiment, a tension spring 16 is preferably installed between the locking arm 9 and the sliding pin 15, that is, the elastic force of the tension spring 16 leaves a gap between the locking arm 9 and the flexible guide rail 10, while not affecting the locking arm 9 to lock the flexible guide rail 10 to achieve self-locking and fall prevention.

[0054] Furthermore, if Figure 9-10As shown, the existing flexible guide rail 10 of the power transmission line is prone to swing and sway when in use. Therefore, in order to limit its swing, anti-sway structures 19 are often arranged at intervals on the flexible guide rail 10. However, this results in the self-locking device being restricted in passing when moving on the flexible guide rail 10, that is, when the self-locking device moves along the flexible guide rail 10 to the anti-sway structure 19 and needs to pass through, it is necessary to manually hold the self-locking device and rotate it around the anti-sway structure 19 to pass through smoothly. The operation is cumbersome and not conducive to quick operation. Therefore, the self-locking device of this embodiment adopts an open groove structure, that is, an open gap 17 is reserved at the installation groove 11 formed by the fixed body and the movable body 1, and the opening gap 17 can be used to smoothly pass through the anti-sway structure 19 installed on the flexible guide rail 10, so that the operation process is convenient, safe and reliable.

[0055] Working principle:

[0056] like Figure 1-10 As shown, when the operator is working at high altitude, he inserts the bottom striker 20 into the self-locking device at the bottom of the tower to open the self-locking device mounting slot 11 and installs the self-locking device on the flexible guide rail 10. After pulling out the striker 20, he only needs to manually push the movable body 1 to reset and manually push the locking pin 6 to reset and penetrate the movable body 1 to complete the closing of the mounting slot 11 of the self-locking device, so that the self-locking device and the flexible guide rail 10 are stably connected and enter a normal working state. Only after the operation is completed and the operator returns to the bottom of the tower, he can manually insert the striker 20 into the self-locking device to open the self-locking device and remove the self-locking device from the flexible guide rail 10, thereby realizing the hidden installation and opening and closing of the anti-fool mechanism, effectively preventing accidental touch during use and improving operation safety.
