As shown in fig. 2, spreader assembly 160 further comprises a reversing pulley assembly 171, which reversing pulley assembly 171 can be connected to the traction rope 164 and can divide the traction rope 164 into a first portion 165, a second portion 166, a third portion 167, and a fourth portion 168 connected in series. The first portion 165, the second portion 166, the third portion 167 and the fourth portion 168 are connected in series to collectively form a ring-like structure. Specifically, first portion 165 may be connected with spreader cord 161. The tail of the first portion 165 is connected to the head of the second portion 166, the tail of the second portion 166 is connected to the head of the third portion 167, the tail of the third portion 167 is connected to the head of the fourth portion 168, and the tail of the fourth portion 168 is connected to the head of the first portion 165.
As shown in connection with FIG. 4, the load cable 164 further includes a cable clamp 190 and a turnbuckle 189, the cable clamp 190 and the turnbuckle 189 being disposed at the third portion 167 to ensure that the first portion 165, the second portion 166, the third portion 167, and the fourth portion 168 are tensioned to form a loop.
Further, the spreading assembly 160 further comprises a first diverting
The first turning
The diverting pulley set 171 is located between the first diverting pulley set 177 and the second diverting pulley set 179 in the extension direction of the rotating assembly 110. The first portion 165 and the second portion 166 are both located between the diverting pulley set 171 and the first spreading guide pulley set 178, the first portion 165 being located below the second portion 166. The third section 167 and the fourth section 168 are each located between the reversing pulley block 171 and the second spreading guide pulley block 180, with the third section 167 being located below the fourth section 168.
Further, the first portion 165 comprises a first connection portion 185, the first connection portion 185 being located between the first diverting
As shown in fig. 9, the first turning
Returning first to fig. 2 and 4, the traction ropes 164 are crossed at the reversing pulley block 171. The first portion 165 is diverted via a first diverting
The second portion 166 is diverted via a first diverting pulley set 177. The second portion 166 is switched from extending along the width of the
The third section 167 is diverted via a second set of diverting pulleys 179. The third portion 167 is switched from extending along the length of the
The fourth portion 168 is diverted via a second set 179 of diverting pulleys. The fourth portion 168 is switched from extending along the width of the
As shown in fig. 8, the diverting pulley block 171 may include a diverting pulley plate 176 and four pulleys (a first pulley 172, a second pulley 173, a third pulley 174, and a fourth pulley 175), and the diverting pulley plate 176 may be connected with the
The first pulley 172 is disposed below the second pulley 173, and the third pulley 174 is disposed below the fourth pulley 175. As shown in connection with fig. 10, the first and fourth portions 165 and 168 may be wound around the first and fourth pulleys 172 and 175, and the second and third portions 166 and 167 may be wound around the second and third pulleys 173 and 174. The first pulley 172, the second pulley 173, the third pulley 174, and the fourth pulley 175 may be misaligned relative to each other. Thus, the first 165, second 166, third 167 and fourth 168 portions are prevented from twisting together as they move, thereby affecting the smoothness of the movement of the load cable 164.
As shown in fig. 2, the first diverting
Further, the second portion 166 includes a second connecting portion 186, the second connecting portion 186 being located between the first diverting pulley set 177 and the first spreading guide pulley set 178. The second connecting portion 186 extends in a direction parallel to the direction of deployment. The second connecting portion 186 may be movable in the collapsing direction. The second connecting portion 186 is connected with one of the two connecting members (the second connecting member 122).
The fourth portion 168 includes a fourth connecting portion 187, the fourth connecting portion 187 being located between the second diverting pulley set 179 and the second spreading guide pulley set 180. The extending direction of the fourth connecting portion 187 is parallel to the deploying direction. The fourth connecting portion 187 may be movable in the collapsing direction. The fourth connecting portion 187 is connected with the other of the two connecting members (the first connecting member 121). The fourth connecting portion 187 and the second connecting portion 186 move in the same direction.
Thus, when the spreading rope 161 drives the first connecting portion 185 to move, the second connecting portion 186 and the fourth connecting portion 187 can synchronously move in the same direction, the second connecting portion 186 drives the second connecting member 122 to move in the spreading direction, and the fourth connecting portion 187 drives the first connecting member 121 to move in the spreading direction, so that the rotating assembly 110 moves in the spreading direction, and the
