[0016] S2. When the second crawler robot reaches the section of wire that needs repair, it simultaneously pushes the locking sleeves onto the wire surface using two push cylinders, securing the two locking sleeves to the intact wire and the wire that needs repair, respectively.

[0017] S3. As the No. 2 crawling robot crawls, the exploration of the section of the wire that needs to be repaired is completed, and the two pushing cylinders operate again, so that the two locking sleeves are fixed on the two ends of the intact wire and the wire that needs to be repaired respectively. Then the operator performs repairs according to the marked sections.

[0018] The present invention has the following beneficial effects:

[0019] 1. This transmission line crossing construction device and method features positioning and locking features. Crawling robots No. 1 and No. 2, working with locking sleeves, precisely mark the locations of wires requiring repair and prevent them from falling when cutting, ensuring construction safety. Regarding clamping effectiveness, the threaded grooves in the clamping plate increase friction with the wires and evenly distribute pressure, ensuring stable clamping while reducing the risk of insulation damage. Regarding operational convenience and accuracy, the threaded grooves adapt to the threaded sections of the wires for optimal positioning. The sliding grooves and ball-head sliders allow the clamping plate to rotate adaptively, facilitating wire insertion.

[0020] 2. The transmission line crossing construction device and method, when the wire to be repaired is cut off, the downward pressure generated by gravity becomes the trigger point of the entire ingenious mechanical linkage; through the cooperation between the pressing cylinder, the main connecting line, the wedge block and the limiting block, the locking sleeve on the wire is pulled by the main connecting line to pull the upper locking sleeve, thereby causing the pressing cylinder to be forced to descend; when the pressing cylinder descends, its side wedge block pushes the limiting block to move, and the limiting block uses the cooperation of the limiting groove to move the force rod upward, and the force plate installed on the upper side of the force rod then applies pressure to the clamping plate, effectively strengthening the clamping force of the clamping plate; and without the need for additional complex operations and power sources, the locking sleeve can better fix the wire, providing a stable and reliable basis for wire maintenance, and further strengthening the clamping force of the clamping plate on the wire.

[0021] 3. This transmission line crossing construction device and method utilizes the coordination between the curved plate, extrusion rod, and disc. When the locking sleeve sways, the coordinated operation of the movable rod and movable cylinder causes the disc to rotate. During the disc's rotation, the extrusion bumps on its surface come into contact with the curved plate, causing it to tip over. Because the curved plate is connected to the extrusion rod above, the plate's tipping rotates the rod, which in turn applies a longitudinal extrusion force to the clamping plate. This longitudinal extrusion force further strengthens the clamping plate's existing grip on the wire, enhancing stability in complex situations such as locking sleeve swaying, and making the entire clamping process more stable and reliable.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: This example aims to solve the problem that in some special environments, such as strong winds or restricted flying areas, drones and helicopters cannot be used normally. When a fault occurs in a wire section, the faulty part needs to be cut, which may cause the wire to fall and cause it to fall from a high altitude. During the repair process of the wire, if the wire can be kept in its original position as much as possible, the problem of additional operations and safety hazards caused by the change of the wire position can be reduced. Please refer to Figures 1-9 A power transmission line crossing construction device and method includes a No. 1 crawling robot 110 and a No. 2 crawling robot 111 installed on the bottom side of the crawling robot. The No. 1 crawling robot 110 and the No. 2 crawling robot 111 are provided with a wire threading groove 112 for the power line to pass through. The No. 1 crawling robot 110 and the No. 2 crawling robot 111 are provided with a placement groove 113, which is connected to the wire threading groove 112. The No. 1 crawling robot 110 and the No. 2 crawling robot 111 store two locking sleeves 114 arranged opposite to each other. A main connecting line 115 is installed between the two locking sleeves 114, and a clamping plate 120 is movably installed inside the locking sleeve 114. A threaded groove adapted to the wire is provided on the surface of the clamping plate 120. A force box 122 is installed on the bottom side of the locking sleeve 114 inside the No. 1 crawling robot 110, and a force plate 123 is installed between the clamping plate 120 and the locking sleeve 114 inside the No. 1 crawling robot 110. A force structure 130 for increasing the clamping force is installed inside the force box 122, and the movable end of the force structure 130 is connected to the force plate 123.

[0034] See Figure 1 、 Figure 2 A pushing cylinder 183 for pushing the locking sleeve 114 is installed inside the placement groove 113, and a driving cylinder 184 for limiting the locking sleeve 114 is installed at the outlet of the placement groove 113. The movable end of the driving cylinder 184 contacts the locking sleeve 114, and an elastic block 185 is installed on the inner wall of the placement groove 113.

[0035] During specific implementation, in the process of inspecting the wires, the No. 1 crawling robot 110 is placed on the surface of the intact wire, and the No. 2 crawling robot 111 is placed in the wire that needs to be repaired. At the same time, the wire passes through the locking sleeve 114. When the No. 1 crawling robot 110 and the No. 2 crawling robot 111 reach the position that needs to be inspected, the two pushing cylinders 183 run at the same time and push the locking sleeve 114 out of the No. 1 crawling robot 110 and the No. 2 crawling robot 111 respectively. At the same time, the movable end of the driving cylinder 184 retracts and loses the obstruction to the locking sleeve 114, so that the locking sleeve 114 is smoothly detached from the inside of the No. 1 crawling robot 110, so that the two locking sleeves 114 are respectively fixed on the intact wire and the wire that needs to be repaired for marking. In the process of continuous movement of the No. 1 crawling robot 110 and the No. 2 crawling robot 111, the cooperation of the locking sleeve 114 is used to lock the position of the wire that needs to be repaired, and the wire section that needs to be repaired is cut off, and the wire will not fall from a high altitude.

[0036] See Figure 3 In a specific implementation, the locking sleeve 114 includes a first connecting block 170 and a second connecting block 171. One end of the first connecting block 170 and the second connecting block 171 is hinged, and the other end of the first connecting block 170 and the second connecting block 171 is fixed with bolts, so that the locking sleeve 114 can be opened for next use.

[0037] See Figure 4 The surface of the clamping plate 120 is symmetrically provided with sliding grooves 172, and the locking sleeve 114 is symmetrically provided with arc grooves 173. A sliding groove 174 is provided inside the locking sleeve 114. The arc groove 173 and the sliding groove 174 are communicated with each other. A ball head slider 175 is slidably matched inside the sliding groove 174. A No. 1 plate 180 is installed on the ball head slider 175. A connecting column 181 is installed on the No. 1 plate 180. The end of the connecting column 181 slides with the sliding groove 172. A second spring 182 is provided on the surface of the connecting column 181. One end of the second spring 182 is connected to the No. 1 plate 180, and the other end of the second spring 182 contacts the clamping plate 120. The surface of the clamping plate 120 is provided with a threaded groove adapted to the wire.

[0038] During specific implementation, since the surface of the wire is usually wrapped with a protective rope, there are threaded sections on the surface of the wire. By opening a threaded groove that is adapted to the wire on the surface of the clamping plate 120, the threaded groove and the threaded section of the wire are adapted to each other, which has a good positioning effect; not only that, through the cooperation of the sliding groove 174 and the ball head slider 175, the clamping plate 120 can be adaptively rotated. When performing the clamping operation, the wire can be easily embedded in the threaded groove and can be accurately in the predetermined position. The second spring 182 can be set to apply pressure to the clamping plate 120. Since the two clamping plates 120 are wrapped, the wire can be clamped, thereby locking the position of the wire.

[0039] In this embodiment: During the operation, the operator first puts the No. 1 crawling robot 110 on the surface of the intact wire, and the No. 2 crawling robot 111 on the wire to be repaired, and allows the wire to pass through the locking sleeve 114; when the two crawling robots arrive at the maintenance position, the cylinder 183 is pushed to operate synchronously to push the locking sleeve 114, and at the same time, the movable end of the cylinder 184 is driven to retract, thereby releasing the obstruction of the locking sleeve 114, so that the locking sleeve 114 is detached from the inside of the robot and fixed on the intact wire and the wire to be repaired respectively, playing a marking role. As the crawling robots continue to Move, and use the locking sleeve 114 to lock the position of the wire to be repaired. Even if the section of the wire is cut off, it will not fall from a high altitude; considering that there is a threaded section on the surface of the wire due to the winding of the protective rope, an adaptive thread groove is opened on the surface of the clamping plate 120, and the two are adapted to each other for positioning; with the help of the sliding groove 174 and the ball head slider 175, the clamping plate 120 can be adaptively rotated, so that the wire can be embedded in the thread groove and accurately positioned; the second spring 182 applies pressure to the clamping plate 120, and the effective locking of the wire position is achieved by wrapping the two clamping plates 120.

[0040] Example 2: This example aims to solve the problem that, although the second spring 182 and the clamping plate 120 can clamp the wire, the actual elastic force may cause unstable clamping. It changes with deformation and environment. If it is too small, the wire will slip easily, and if it is too large, it will easily damage the wire and plate. Vibration and wind in the power transmission environment will also interact with it, exacerbating instability and affecting locking. This example is an improvement made on the basis of Example 1. For details, please refer to Figures 1-9 The force-applying structure 130 includes a placement box 131 installed inside the force-applying box 122, a pressing cylinder 132 installed inside the placement box 131, and two parallel wedge blocks 133 are integrally installed on the inner wall of the pressing cylinder 132. A support column 134 is installed inside the placement box 131, and a force-applying rod 135 is slidably installed inside the support column 134. One end of the force-applying rod 135 is connected to the force-applying plate 123, and a movable groove 140 is provided on the support column 134. A limiting block 141 adapted to the inclined surface of the wedge block 133 is installed inside the movable groove 140, and a limiting groove 142 is provided on the force-applying rod 135. The middle section of the limiting block 141 slides inside the limiting groove 142, and a first spring 143 is sleeved on the surface of the force-applying rod 135. One end of the first spring 143 is connected to the inner wall of the pressing cylinder 132, and the other end of the first spring 143 is connected to the support column 134.

[0041] See Figure 4 、 Figure 5 and Figure 6 One end of the main connecting line 115 is divided into several branch connecting lines 144, and the several branch connecting lines 144 are installed in a ring array on the bottom side of the pressing cylinder 132. The upper side of the force plate 123 is symmetrically installed with a resistance protrusion 145, and the resistance protrusion 145 is in contact with the clamping plate 120.

[0042] See Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In a specific implementation, since the locking sleeve 114 cooperates to lock the position of the wire to be repaired, and after the wire to be repaired is cut off, since the wire to be repaired has no supporting force, the wire to be repaired generates downward pressure due to gravity, so the locking sleeve 114 set on the wire to be repaired will pull the locking sleeve 114 above. Since the two locking sleeves 114 are equipped with the main connecting wire 115, the main connecting wire 115 will be pulled downward. Since the branch connecting wire 144 branched from the main connecting wire 115 will pull the pressing cylinder 132, when pressing As the pressure cylinder 132 descends, the wedge block 133 installed on the side of the pressure cylinder 132 will generate a thrust on the limiting block 141, so that the limiting block 141 moves. During the movement of the limiting block 141, the cooperation of the limiting groove 142 is used to make the force rod 135 move upward. Since the force plate 123 is installed on the upper side of the force rod 135, pressure is generated on the clamping plate 120 during the upward movement of the force rod 135, so that the clamping force of the clamping plate 120 is strengthened, so that the locking sleeve 114 can better fix the wires.

[0043] In this embodiment: through the cooperation of the pressing cylinder 132, the main connecting line 115, the wedge block 133, the limiting block 141 and the downward pressure generated by gravity after the wire to be repaired is cut off, the locking sleeve 114 sleeved on the wire will pull the upper locking sleeve 114 using the main connecting line 115, so that the pressing cylinder 132 is forced to descend. During the process of the pressing cylinder 132 descending, the wedge block 133 on the side of the pressing cylinder 132 pushes the limiting block 141 to move. During the movement of the limiting block 141, the cooperation of the limiting groove 142 is used to make the force rod 135 move upward, and the force plate 123 installed on the upper side of the force rod 135 generates pressure on the clamping plate 120, thereby strengthening the clamping force of the clamping plate 120 and allowing the locking sleeve 114 to better fix the wire.

[0044] Example 3: This example aims to solve the problem that although the force rod 135 and the force plate 123 cooperate to strengthen the wire clamping force, the stability of the horizontal clamping force is poor and the wire is easily displaced due to longitudinal tension, vibration, etc. This example is an improvement made on the basis of Example 2. For details, please refer to Figures 1-9The force structure 130 also includes a disc 150 movably arranged in the force box 122, and extrusion protrusions 151 are symmetrically installed on the disc 150. An opening 152 is provided on the bottom side of the force box 122, and a support rod 153 is installed between the openings 152. The disc 150 is hinged on the support rod 153, and an arc plate 154 is symmetrically installed inside the force box 122. An extrusion rod 155 is installed on the arc plate 154. A connecting groove 160 for the extrusion rod 155 to move is provided on the locking sleeve 114 in the No. 1 crawling robot 110. The end of the extrusion rod 155 contacts the clamping plate 120, and the extrusion protrusion 151 contacts the side of the arc plate 154.

[0045] A connecting rod 161 is installed inside the force box 122, the bottom side of the arc plate 154 is hinged to the connecting rod 161, a torsion spring 162 is installed between the connecting rod 161 and the arc plate 154, a movable rod 210 is installed on the bottom side of the disc 150, a movable cylinder 211 is installed on one of the locking sleeves 114, and a telescopic spring 212 is installed between the movable rod 210 and the movable cylinder 211.

[0046] See Figure 7 、 Figure 8 and Figure 9 During the specific implementation, since the wires are hung in the air due to the influence of strong winds, the wires that need to be repaired have no supporting force and thus shake, so the locking sleeve 114 set on the wires that need to be repaired swings, and during the swinging process of the locking sleeve 114, the movable rod 210 cooperates with the movable cylinder 211 to cause the disc 150 to rotate. Therefore, during the rotation of the disc 150, the extrusion protrusion 151 cooperates to resist the arc plate 154, and at this time the arc plate 154 tilts over. During the tilting process of the arc plate 154, the extrusion rod 155 above is driven to rotate, and during the rotation process of the extrusion rod 155, the clamping plate 120 is squeezed, so that the clamping plate 120 is subjected to force, resulting in an increase in the clamping force, so that the clamping plate 120 can better clamp the wire, further strengthening the clamping force of the clamping plate 120 on the wire.

[0047] This proposal also proposes a transmission line crossing construction method, including the following steps:

[0048] S1. The crawling robot No. 110 is set on the wire, and the crawling robot No. 2 111 is set on the wire that needs repair;

[0049] S2. When the crawling robot 111 crawls to the section where the wires need to be repaired, the two cylinders 183 simultaneously push the locking sleeve 114 to the surface of the wires, so that the two locking sleeves 114 are fixed to the intact wires and the wires that need repair;

[0050] S3. As the No. 2 crawling robot 111 crawls, the exploration of the section of the wire that needs to be repaired is completed, and the two pushing cylinders 183 operate again, so that the two locking sleeves 114 are respectively fixed on the two ends of the intact wire and the wire that needs to be repaired. Then the operator performs repairs according to the marked sections.

[0051] In this embodiment: through the cooperation of the curved plate 154, the extrusion rod 155 and the disc 150, during the swinging process of the locking sleeve 114, the cooperation between the movable rod 210 and the movable cylinder 211 is used to rotate the disc 150; during the rotation of the disc 150, the extrusion protrusions 151 on its surface come into contact with the curved plate 154, causing the curved plate 154 to tip over. Since the curved plate 154 is connected to the extrusion rod 155 above, the tipping of the curved plate 154 will drive the extrusion rod 155 to rotate together. As the extrusion rod 155 rotates, an extrusion force is applied to the clamping plate 120 in the longitudinal direction. After being squeezed, the clamping plate 120 will further increase the clamping force on the wire, thereby more effectively fixing the wire, making the entire clamping process more stable and reliable.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
