As shown in fig. 1, the guide rail base plate 112 in this embodiment is oriented perpendicular to the ground surface, so that the opening of the limiting groove 113 is perpendicular to the ground surface. Also, as shown in fig. 7, the location of the guide rail loop 120 is at 1/2 the radius of the top of the rotor, and the length of the cable is also 1/2 the radius, so that the service area can be limited to just the top of the rotor.

As shown in fig. 2, the guide rail section 110 includes a guide rail base plate 112 and a limiting bar 111, the guide rail base plate 112 is fixed on the top of the rotor by bolts, the limiting bar 111 protrudes out of the guide rail base plate 112, and the limiting bar 111 and the guide rail base plate 112 surround to form a limiting groove 113.

Specifically, the cross section of the limiting strip 111 in this embodiment is T-shaped, two limiting strips 111 are arranged on each guide rail section 110 in parallel, and a T-shaped limiting groove 113 is formed between the two limiting strips 111. And both sides of the position-limiting strip 111 also extend for a part of the length.

As shown in fig. 3, the slider 210 in the present embodiment includes a limit plate 211 and a link 212, wherein the width of the limit plate 211 is smaller than the opening width of the limit groove 113, and the length of the limit plate 211 is greater than the opening width of the limit groove 113. When the fastener 230 is installed, the width direction of the limiting groove 113 is placed to be parallel to the length direction of the limiting groove 113, the limiting plate 211 is inserted into the limiting groove 113, and the limiting plate 21190 degrees is rotated, so that the limiting plate 211 cannot be moved out from the opening of the limiting groove 113, and the buckling installation is realized. Thus, the stopper plate 211 has a locked position in the stopper groove 113 and cannot be removed, and can move out of the unlocked position. Meanwhile, the width of the inside of the limiting groove 113 is greater than the length of the limiting plate 211, so as to ensure that the sliding member 210 can move smoothly in the limiting groove 113.

As shown in fig. 4, the fastening member 230 in this embodiment includes a fastener body 231, and the sliding member 210 and the mounting ring 232 are respectively disposed at two ends of the fastener body 231; the operation structure 220 is connected to the sliding member 210 and rotatably disposed on the buckle body 231. Specifically, a mounting loop 232 is provided on the end of the handle structure 220, and the cord is threaded through the mounting loop 232, thereby keeping the cord away from the rail segment 110 and avoiding entanglement between the rail segment 110 and the fastener 230.

As shown in fig. 5, the operation plate in this embodiment includes an operation lever 221, a locking plate 222 and a locking piece 223, wherein one end of the operation lever 221 is connected to the slider 210, and the other end thereof passes through a rotation hole 231a of the buckle body 231 for directly driving the slider 210 to rotate. The locking plate 222 is fixed on the buckle body 231 and is provided with a locking groove; and a locking piece 223 coupled to the operating lever 221, rotated on the locking plate 222, and adapted to be inserted into the locking groove. The locking piece 223 is in the form of a long rod, has a longitudinal direction perpendicular to the axial direction of the operating lever 221, and can be locked at different positions as the operating lever 221 rotates.

Specifically, as shown in fig. 6, a through hole 222a communicated with the rotation hole 231a is formed in the lock plate 222, the locking grooves include a first locking groove 222b and a second locking groove 222c which are vertically arranged, the first locking groove 222b and the second locking groove 222c are long waist holes capable of accommodating the lock piece 223, and are formed in the same surface of the lock plate 222 and are blind holes. A through hole 222a is opened at a crossing position of the first locking groove 222b and the second locking groove 222 c. After the locking piece 223 enters the locking groove, it contacts with the sidewall of the locking groove, and the rotation of the operating lever 221 is blocked and cannot be rotated, so that the position locking is realized. Specifically, when the locking piece 223 enters the first locking groove 222b, the short edge of the limiting plate 211 is parallel to the direction of the limiting groove 113, that is, the sliding element 210 is in the locking state and cannot be moved out of the limiting groove 113, and when the locking piece 223 enters the second locking groove 222c, the short edge of the limiting plate 211 is perpendicular to the direction of the limiting groove 113, that is, the sliding element 210 is in the unlocking state and can be moved out of the limiting groove 113.

When the fastener 230 needs to be temporarily detached from the rail section 110, the operation rod 221 needs to be rotated by 90 degrees, so that the matching switching between the slider 210 and the rail member can be realized, and during installation, the fastener 230 and the rail section 110 can be fastened by continuously rotating the operation rod 221 by 90 degrees. The operation is simple and quick.

In order to maintain the stability of the operating structure 220, as shown in fig. 5, the operating rod 221 moves linearly along the axial direction of the rotating hole 231a, the operating rod 221 in this embodiment is provided with a reset member, which includes a check plate 221a disposed on the operating rod 221 and a spring 221b disposed between the check plate 221a and the buckle body 231, and the spring 221b applies a force to the check plate 221a to make the locking piece 223 approach the locking plate 222, so that the locking piece 223 can be kept tightly attached to the inner wall of the locking groove, and the locking piece 223 is prevented from automatically sliding out of the locking groove, so that the connection of the fastening member 230 fails. When the operating lever 221 needs to be rotated, the locking piece 223 can be rotated only after the locking piece 223 is moved out of the locking groove by overcoming the elastic force of the spring 221b, and when the operating lever is rotated in place, the locking piece 223 is automatically pushed into the locking groove by the spring 221b, so that automatic reset is realized.

Specifically, as shown in fig. 4 and 5, the buckle body 231 is formed with a mounting cavity 232a, the check plate 221a and the spring 221b are disposed in the mounting cavity 232a, and two ends of the spring 221b abut between the mounting cavity 232a and the check plate 221a, wherein one end of the spring 221b abuts on an end surface of the mounting cavity 232a on a side close to the slider 210, the check plate 221a is formed and located at a middle portion in the mounting cavity 232a with the lever, the spring 221b is in a compressed state and applies a pushing force to the check plate 221a, and the locking plate 222 is formed on an end of the mounting cavity 232a far from the slider 210, and the locking piece 223 is tightly pushed to the locking plate 222 due to the pushing force. When the operating lever 221 is rotated, the operating lever 221 is pushed toward the slider 210, so that the locking piece 223 moves out of the locking groove, and when the operating lever 221 is rotated by 90 degrees, the spring 221b automatically pushes the locking piece 223 into the locking groove by releasing the operating lever 221.

And the mounting ring 232 is arranged at the end part of the operating rod 221, and in the process of maintenance operation, the rope can pull the operating rod 221 outwards, so that the locking piece 223 is further tightly attached to the locking plate 222, the locking piece 223 is prevented from automatically moving out of the locking groove, and the stability of the structure is improved.

In order to prevent the installed fastener 230 and the rail member from rotating relatively and then changing the direction of the position limiting plate 211, as shown in fig. 1, the buckle assembly 200 in this embodiment further includes a baffle 240, and the baffle 240 is disposed at two sides of the buckle body 231 and extends downwards from two sides of the buckle body 231, so that the baffle 240 contacts with the outer sides of the two position limiting strips 111, and the distance between the two position limiting strips is slightly larger than the outermost width of the position limiting strips 111. Due to the existence of the baffle 240, the buckle body 231 cannot rotate around the connecting rod 212 and the guide rail section 110, so that the directional stability of the limiting plate 211 is maintained.
