[0034] 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.

[0035] Example 1

[0036] See also Figure 1 A cable crane hoisting system is provided between two towers. A load-bearing cable 2 is provided on the top of the two towers. The load-bearing cable 2 belongs to the prior art and will not be described in detail here. The system comprises: a guide wheel 1, a load-bearing cable 2, a winch device 3, a pulley block 4, a crown block assembly 5 and a traction cable 6; Figure 1 There are two identical lifting systems, which are installed on two towers. Figure 1 It can be seen that each lifting and hoisting system can be used independently without affecting each other, and can be used in any combination to improve work efficiency;

[0037] A guide wheel 1 is provided on the tower, and a guide wheel 2 is provided on one side of the guide wheel 1. The guide wheel 1 and the guide wheel 2 are used to move from one tower to another tower when the traction rope 6 is passed through, and then return to the original position from the other tower; the winch device 3 and the pulley block 4 are both provided under one tower, and one end of the traction rope 6 passes around the pulley block 4 and then connects to the winch device 3, and the other end of the traction rope 6 passes around the guide wheel 1 on the same side of the winch device 3, the guide wheel 1 on the other side of the tower, and the guide wheel 2 and the pulley block 4 on the same side of the winch device 3 to form a closed loop, and then connects to the winch device 3 from the attached Figure 1 It can be seen that the cross-section of the traction rope 6 between the two sets of towers is U-shaped; the overhead crane assembly 5 is arranged on the traction rope 6 and is driven by the traction rope 6 to move along the load-bearing rope 2. Specifically, the traction rope 6 is divided into two sections, one end of one section is connected to one end of the overhead crane assembly 5, and one end of the other end is connected to the other end of the overhead crane assembly 5. Under the action of the winding and unwinding of the traction rope 6 by the winch device 3, the movement of the overhead crane assembly 5 is realized; the winch device 3 preferably adopts a double-drum friction winch.

[0038] Preferably, the overhead travelling crane assembly 5 of this embodiment includes an upper bracket 51, a traveling wheel 52, a connecting portion 53, a lifting fixed pulley device and a locking hook portion 56;

[0039] There are at least two groups of upper hangers 51, and the bottoms of at least two groups of upper hangers 51 are movably connected to the connecting portion 53;

[0040] There are at least two sets of running wheels 52, which are spaced apart at both ends of one side of the upper hanging frame 51, and are used for the upper hanging frame 51 to move on the load-bearing cable 2;

[0041] The lifting fixed pulley device is provided below the connecting portion 53 and includes a plurality of fixed pulley assemblies 54, a movable frame, and a plurality of movable pulley assemblies 55 provided on the movable frame. The fixed pulley assemblies 54 and the movable pulley assemblies 55 correspond to each other one by one, and any movable pulley assembly 55 is linked to the corresponding fixed pulley assembly 54 via the lifting cable 9. The structures of the lifting fixed pulley device and the fixed pulley assemblies 54 and the movable pulley assemblies 55 in the lifting fixed pulley device have been disclosed in the cable crane crown block proposed in the existing publication number CN212832467U and belong to the prior art, and will not be described in detail here.

[0042] The locking hook portion 56 is disposed at the bottom of the movable frame.

[0043] As a preferred embodiment, the present embodiment further includes a plurality of groups of cable supports 7, which are spaced apart on the load-bearing cable 2 to support the traction cable 6 and the lifting cable 9; for example, the cable supports are spaced apart at a distance of 30 meters.

[0044] As a preference, one side of the guide wheel 1 of this embodiment is further provided with a traction rope pitch wheel 8, which is movably arranged in the tower. Figure 1 As shown, the distance between the two horizontal sections of the traction rope wound between the two groups of towers is adjusted by moving the traction rope spacing wheel 8.

[0045] Example 2

[0046] Because the load-bearing cable 2 is usually sealed steel wire rope, and the load-bearing cable 2 is easily affected by friction, dust and other factors during outdoor use, which can easily affect the stable operation of the overhead crane assembly 5 and cause damage to the load-bearing cable 2. Therefore, please refer to Figure 2-3 , the crown block assembly 5 of this embodiment further includes: an oil storage box 57, a connecting seat 511, a processing shell 512, a rotating column 513 and an oiling portion;

[0047] The oil storage box 57 is detachably connected to an upper hanger 51 via a bracket. A valve body is provided at the outlet end of the oil storage box 57, and an oil supply pipe is provided on one side of the oil storage box 57. When lubrication of the load-bearing cable 2 is not required, the valve body can be closed. When the lubricating oil in the oil storage box 57 is used up, the lubricating oil can be replenished by connecting the oil supply pipe through an external device.

[0048] The connecting base 511 is inserted into the top of the processing shell 512. A cavity for accommodating the rotating column 513 is provided in the connecting base 511. The inlet end of the connecting base 511 is connected to the outlet end of the oil storage box 57. The outlet end of the connecting base 511 extends to the inner cavity of the processing shell 512.

[0049] The bottom of the processing shell 512 is hollow and has notches at both ends to allow the oiling portion to be sleeved on the load-bearing cable 2. A support frame 515 is provided inside the processing shell 512.

[0050] The rotating column 513 is rotatably mounted within the cavity of the connecting seat 511 via an axis. A plurality of grooves 514 are formed on the circumferential outer wall of the rotating column 513. It should be noted that the inlet and outlet ends of the connecting seat 511 correspond to a set of grooves 514 on the rotating column 513, respectively. This arrangement prevents the lubricating oil in the oil reservoir 57 from being discharged when the overhead travelling vehicle assembly 5 is not traveling on the load-bearing cable 2.

[0051] An oiling portion is provided in the support frame 515 and below the outlet end of the connecting seat 511, and is used to clean and apply lubricating oil to the load-bearing cable 2;

[0052] The axis of the rotating column 513 extends through the side wall of the connecting seat 511 and is connected to the axle of the running wheel 52 in the upper bracket 51 via a transmission member 1 58. As the running wheel 52 moves on the load-bearing cable 2, the axle of the running wheel 52 drives the rotating column 513 via the transmission member 1 58. The rotating column 513 intermittently rotates, collects lubricating fluid through the groove 514, and then pours it onto the oiling portion as it rotates.

[0053] See also Figure 4 As an example, the oiling portion of this embodiment includes an arc-shaped transmission belt 516, a driving gear 518, a transmission member 3 519 and a transmission rod 520;

[0054] The arcuate transmission belt 516 is closed end to end and is arranged outside the multiple groups of rotating columns 513. The multiple groups of rotating columns 513 are arranged in an arc-shaped array and rotated within the support frame 515. The inner wall of the arcuate transmission belt 516 is provided with teeth and grooves, and the outer wall of the arcuate transmission belt 516 is provided with wear-resistant oiled cotton 510 that fits the outer wall of the load-bearing cable 2. The wear-resistant oiled cotton 510 can be made of a wear-resistant sponge material, for example. The rotating column 513 is used to support the arcuate transmission belt 516 so that the arcuate transmission belt 516 circulates along the arcuate path. The arcuate transmission belt 516 can be wrapped around the outer side of the load-bearing cable 2 to clean and oil the outer wall of the load-bearing cable 2 during transmission.

[0055] Two sets of drive gears 518 are provided, one at each end of the inner side of the arc-shaped transmission belt 516 and meshing with the tooth grooves on the outer inner wall of the arc-shaped transmission belt 516. The drive gears 518 are sleeved on the outer wall of the active rod 517. The two sets of active rods 517 are both located in the support frame 515 and are connected by the third transmission member 519. The two sets of drive gears 518 rotate synchronously in the same direction, driving the arc-shaped transmission belt 516 to transmit the power. The third transmission member 519 causes the two sets of active rods 517 to rotate synchronously in the same direction.

[0056] The transmission rod 520 is inserted into the outer wall of the processing housing 512 and is parallel to the axis of the rotating column 513. One end of the transmission rod 520 is connected to one of the sets of active rods 517 via a transmission member 4, and the other end of the transmission rod 520 is connected to the axis of the rotating column 513 via a transmission member 2 59. When the rotating column 513 rotates, the transmission member 2 59 drives the transmission rod 520, which in turn drives one of the sets of active rods 517 via the transmission member 4. One set of active rods 517 drives the other set of active rods 517 via the transmission member 3 519, thereby causing the two sets of drive gears 518 to rotate synchronously in the same direction.

[0057] Transmission member 1 58, transmission member 2 59 and transmission member 3 519 are all sprocket chain transmission groups, the sprocket chain transmission group is a chain and a sprocket, transmission member 4 is a turbine and vortex transmission group, the turbine and vortex transmission group is a turbine and a vortex. Of course, transmission member 1 58, transmission member 2 59, transmission member 3 519 and transmission member 4 are not limited to the above structure.

[0058] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
