To ensure that the overall cross-sectional diameter dimension of the thick strands 102 is greater than the overall cross-sectional diameter dimension of the thin strands 103, the number of first wires and second wires in each strand may be kept equal, but the diameter of the first wires is greater than the diameter of the second wires. It is also possible to keep the first and second steel filaments equal in diameter, but with a greater number of first steel filaments per strand than second steel filaments per strand.
In this embodiment, the rope core 103 may be made of hemp rope, or may be made of a plurality of thin steel wires by twisting.
In this embodiment, as shown in fig. 1, the ground anchor 4 has a pit anchor structure. The two ends of the cable 1 are effectively and fixedly connected with the anchor blocks so as to have anchoring and traction effects with enough margin.

When the tread driving wheel 22 is matched with the cable 1, the tread driving wheel can be meshed with the meshing groove 100 through the meshing teeth 221 to form a transmission structure similar to a rack and pinion, so that the self-propelled trolley 2 does not need to consider the situation of slipping when the goods 500 are transported along the cable 1, and the transportation capacity of the goods 500 is improved.
In this embodiment, as shown in fig. 10, the depth of the engaging groove 100 in the axial section of the cable 1 is k, and in order to ensure the transmission stability of the engaging teeth 221 and the engaging groove 100, k is 5% -20%, preferably 10%, of the radius of the circumscribed circle of the cable 1.
In this embodiment, as shown in fig. 3, the force analysis of the engagement rolling of the tread driving wheel 22 along the cable 1 can be performed, and the circumferential driving force of the driving device 24 to the tread driving wheel 22 through the output end is F N1 When the engagement teeth 221 of the tread driving wheel 22 engage with the engagement grooves 100, the circumferential driving force F of the tread driving wheel 22 N1 The cable 1 can generate a reaction force F in the axial direction of the cable 1 by pressing the engaging groove 100 with a component force in the normal direction of the spiral direction of the engaging teeth 221 L2 And a support reaction force F in the circumferential direction N2 In which axial bearing reaction force F L2 Can be used for counteracting the gravity component F of the goods 500 on the self-propelled trolley 2 L1 To enable transport of the cargo 500; and a support reaction force F in the circumferential direction N2 This results in a self-rotation of the cable 1, which in turn results in a swinging movement of the self-propelled carriage 2 along the cable 1 and a twisting run of the cable 1.
In this embodiment, the circumferential reaction force F generated by the tread driving wheel 22 moving in cooperation with the cable 1 is balanced N2 . As shown in fig. 3 to 5, the balance assembly 23 is located below the tread driving wheel 22, and the balance assembly 23 includes a pair of tread tensioning wheels 231, a balance beam 232, and a hand wheel screw 233. Wherein compensating beam 232 and frame link plate 21 sliding connection, two tread take-up pulleys 231 rotate respectively and install in compensating beam 232 both ends to make two tread take-up pulleys 231 slide from top to bottom along frame link plate 21 under compensating beam 232's drive, and then can cooperate the cable 1 of tread drive wheel 22 both sides, and tread take-up pulley 231 is the same with tread drive wheel 22 structure, so that tread take-up pulley 231 all produces with circumference counter-force F in the both sides of cable 1 N2 Equal and opposite forces, thereby realizing the circumferential support reaction force F N2 Carry out the balance, and then guarantee that proper motion dolly 2 drives goods 500 and stabilizes the transportation along cable 1. Meanwhile, the hand wheel screw rod 233 is in threaded connection with the frame hanging plate 21, and the upper end of the hand wheel screw rod 233 is connected with the balance beam 232, so that the balance beam 232 can slide up and down along the frame hanging plate 21 under the rotation of the hand wheel screw rod 233 along the threads of the frame hanging plate 21, and the balance beam 232 is ensured to drive the tread tension wheel 231 to keep continuous stability with the matching of the cable 1.
In one embodiment of the present application, as shown in fig. 13 and 14, the outer surface of the cable 1 may be considered as a lead surface structure comprising a plurality of helical raceways 100. A pair of limiting plates 213 are fixed in the middle of the frame hanging plate 21; the driving part is a driving sliding sleeve 25, the driving sliding sleeve 25 is rotatably connected with the limit plate 213, and the driving sliding sleeve 25 is matched with the side part of the limit plate 213 through a baffle 251 arranged at two ends, so that the driving sliding sleeve 25 is integrated with the frame hanging plate 21 in the axial direction. A sliding hole 250 is formed in the center of the driving sliding sleeve 25, a plurality of spiral sliding grooves are formed in the side portions of the sliding hole 250, and a plurality of balls 26 are mounted in the spiral sliding grooves; when the driving sliding sleeve 25 is matched with the cable 1, the cable 1 passes through the sliding hole 250 and is matched with the ball 26 through the spiral raceway 110 to form a screw slider transmission structure.

When the driving sliding sleeve 25 is driven by the driving device 24, it rotates around the limiting plate 213, and the axial movement of the driving sliding sleeve 25 is limited by the limiting plate 213, so that the driving sliding sleeve 25 can drive the whole self-propelled trolley 2 to move up and down along the cable 1, thereby realizing the transportation of the goods 500.
It can be understood that the screw-slider transmission structure formed by the cable 1 and the driving sliding sleeve 25 via the spiral raceway 110 does not need to consider the problem of slipping during the transportation of the cargo 500, and the rolling friction force of the balls 26 is small, so that the driving force of the driving device 24 only needs to be slightly larger than the gravity component F of the cargo 500 L1 Can realize 500 transports of goods to compare traditional plain noodles cable, this embodiment screw rod slider transmission structure's cable 1 and drive sliding sleeve 25 also can effectual improvement 500 transport volume of goods.
