The specific embodiment
Shown in accompanying drawing 1-3, the present invention mainly designs according to lever principle, described lever principle also claims " lever equilibrium condition ", make lever balance, and the size that acts on two power (power point, fulcrum and resistance point) on the lever follows their arm of force to be inversely proportional to.In view of the above as can be seen: when the transportation weight hangs on the hauling rope gripping mechanism spanner 6 outer end hinges, spanner 6 is that fulcrum rotates the chucking hauling rope with fixed pin shaft 7, because the distance of upper holder block 5 and fixed pin shaft 7 is less than the distance of spanner 6 outer hinges and fixed pin shaft 7, so thrust greater than conveying objects gravity, helps guaranteeing chucking pressure.
In the present invention, the distance of adjustment spanner 6 China and foreign countries' hinges 8, upper holder block 5 and fixed pin shaft 7 can be regulated the thrust between the upper and lower briquetting.
Gripping mechanism of the present invention is to use lever principle to realize chucking and throw off work time-division two kinds of operating modes: 1. tighten hauling rope B.When beginning to transport, install after cargo transport dolly D and the gripping mechanism A, spanner 6 among the gripping mechanism A is cocked from outer hinge, drive upper holder block 5 upward movements and leave lower lock block 4 to apart from greater than hauling rope B diameter, put into hauling rope B, hang up transportation weight C then and can realize the hauling rope chucking; 2. unclamp hauling rope B.Be transported to after the assigned address, remove transportation weight C, spanner 6 among the gripping mechanism A is cocked from outer hinge, drive upper holder block 5 upward movements and leave lower lock block 4 to apart from greater than hauling rope B diameter, take out hauling rope and can realize the hauling rope disengagement.
The first secondary arm-tie 2 and the second secondary arm-tie 3 are all fixed with main arm-tie 1 among the present invention, and the gap greater than the hauling rope diameter is reserved in the centre, easily hauling rope is put into and is taken out to be implemented under the situation of not disassembling gripping mechanism.
In cableway was installed, the dolly D that will freight earlier was installed on the ropeway carrying-rope E, and the dolly D that will freight then is connected with ropeway hauling rope gripping mechanism A with transporting between the weight C.
