Example 1:
as shown in fig. 1 and 2, a multifunctional steel wire rope pay-off device capable of being disassembled is used for paying off a wound steel wire rope 5 on a crane installation site, and comprises a base 1 and a rotating disc 2 rotatably connected with the base 1. In this embodiment, the base 1 and the rotating disc 2 are connected in a horizontal rotating manner. The connecting surface of the base 1 and the rotating disk 2 in rotating connection is a horizontal disk surface, and a rotating shaft is arranged in the center of the disk surface. A rotating shaft hole corresponding to the rotating shaft is formed in the center of the rotating disc 2, a bearing 6 mounted on the rotating shaft is a thrust bearing, and the rotating disc 2 is rotatably connected with the base 1 through the thrust bearing. Because the base 1 is connected with the rotating disk 2 in a horizontal rotating mode, and the force mainly borne between the base 1 and the rotating disk 2 is axial force, a thrust bearing is selected as the bearing.
Since the reeling rope 5 is usually of a larger diameter and also heavier, tilting can occur. In order to prevent the winding wire rope 5 from inclining, a measure of increasing the supporting area of the rotating disc 2 can be taken, therefore, a plurality of universal balls 7 which are evenly distributed along the circumferential direction of the disc of the base 1 are also arranged on the base 1, and the universal balls 7 are in rolling contact with the rotating disc 2.
A plurality of rotary frames 3 for supporting the winding steel wire rope 5 are arranged on the rotary disc 2, and the rotary frames 3 extend outwards along the radial direction of the rotary shaft hole of the rotary disc 2 and are uniformly distributed about the rotary shaft. And a connecting disc 8 is further arranged on the rotating disc 2, a bearing hole is formed in the connecting disc 8, and a thrust bearing is arranged in the hole and is rotatably connected with the rotating shaft on the base 1. The connecting disc 8 is also provided with a plurality of connecting holes corresponding to the rotary frames 3 and the rotary disc 2, and the connecting disc 8, the rotary disc 2 and the rotary frames 3 positioned between the connecting disc 8 and the rotary disc 2 are connected through positioning bolts.
Because the reversing frames 3 are longer, in order to increase the supporting rigidity of the plurality of reversing frames 3 to the winding steel wire rope 5, one end of each reversing frame 3, which is far away from the rotating shaft hole, is provided with a threaded hole, an arc-shaped connecting plate 9 is arranged between every two adjacent reversing frames 3, and the arc-shaped connecting plate 9 is connected in the threaded hole of the corresponding reversing frame 3 through a bolt. A plurality of arc connecting plates 9 are connected with a plurality of reversing frames 3 in the circumferential direction, so that the integral rigidity of the plurality of reversing frames 3 is enhanced.
Each of the turning frames 3 is provided with a plurality of inner stop lever mounting holes in a direction extending radially outward along the rotating shaft hole, one inner stop lever 4 is mounted in one of the inner stop lever mounting holes, and the inner stop lever 4 on each of the turning frames 3 is parallel to the rotating shaft.
In this embodiment, the winding wire 5 is stored in a whole roll, and the wire is wound on the hollow roller packing frame in a roll. Because the hollow roller packaging frame provided by each manufacturer is different, the diameters of the hollow holes are also different, so the installation positions of the inner stop rods 4 on the respective rotary frames 3 are adjusted, a plurality of inner stop rods 4 can be simultaneously inserted into the hollow holes of the hollow roller packaging frame with proper gaps, and the hollow roller packaging frame can be positioned by contacting with the inner stop rods 4. At this time, since the plurality of inner bars 4 have the same distance from the rotation axis, it is ensured that the winding wire rope 5 wound on the hollow roll packing frame is coaxial with the rotation axis.
So far, the winding steel wire rope 5 can be coaxially placed on the rotating disc 2, and the rope head is pulled to rotate along the rotating axis of the rotating disc 2, and the rotating disc 2 and the base 1 rotate in a rolling manner and are axially supported by the universal balls 7, so that the traction force required by rope unwinding is small, the labor intensity of an operator is small, the efficiency is high, and additional hoisting equipment does not need to be occupied.
Example 2:
the rotary connection between the base 1 and the rotary disk 2 in the embodiment 1 is horizontal rotary connection, and the rope unwinding device is suitable for winding the steel wire rope 5 and placing the rope unwinding device at a place far away from the winding drum, and the steel wire rope can be unwound and wound at a small traction angle. If the winding steel wire rope 5 and the rope releasing device are placed at a place close to the winding drum, the angle of the upper rope is large in traction, the steel wire rope and the inner rotating stop lever 4 can interfere when the rope is released, and in addition, the traction force required by rope releasing is large. In order to realize rope paying-off and rope loading at a short distance, the embodiment adopts an inclined rotation technical scheme.
The detachable multifunctional steel wire rope pay-off device in the embodiment 1 is different from the embodiment 1 in that, as shown in fig. 3, the rotating connection between the base 1 and the rotating disc 2 is an inclined rotating connection; the connecting surface of the base 1 and the rotating disk 2 in rotating connection is an inclined disk surface, and a rotating shaft is arranged in the center of the disk surface. The center of the rotating disk 2 is provided with a rotating shaft hole corresponding to the rotating shaft, a bearing 6 arranged on the rotating shaft is an angular contact bearing, and the rotating disk 2 is rotatably connected with the base 1 through the angular contact bearing. The angular contact bearing can bear axial force and radial force at the same time so as to bear the axial force and the radial force generated on the rotating shaft by the winding steel wire rope 5 due to inclination. Similarly, the connecting disc 8 is provided with a bearing hole, and an angular contact bearing is arranged in the bearing hole and is rotationally connected with the rotating shaft on the base 1 to form a double-bearing support.
In this embodiment, the winding wire rope 5 is in the whole coil storage state, and when the winding wire rope 5 winds up the coil, the inner diameter of the coil is different. Therefore, the installation position of each inner stopper 4 on each turret 3 is adjusted so that the plurality of inner stoppers 4 can be simultaneously inserted into the inner ring of the winding wire 5 with a suitable gap, and the winding wire 5 can be positioned by contacting the plurality of inner stoppers 4. At this time, since the plurality of inner bars 4 have the same distance from the rotation axis, the winding wire 5 in the entire disc storage state is ensured to be coaxial with the rotation axis.

So far, because the inner stop levers 4 support the inner ring of the winding steel wire rope 5, the whole steel wire rope disc can not be twisted, slipped and knotted under the action of traction force, thereby improving the quality and efficiency of rope unwinding and rope feeding. Because the swivelling joint of base 1 and rotary disk 2 is the slope swivelling joint, wire rope can put the rope, go up the rope with very big angle of pulling, therefore it is little to occupy the place, and wire rope hangs off ground moreover, can not glue the adhesion debris.
In embodiment 1, the base 1 and the rotary disk 2 are detachably connected; the plurality of revolving frames 3 are connected with the plurality of arc-shaped connecting plates 9 through bolts; the connecting disc 8, the rotating disc 2 and the plurality of rotary frames 3 positioned between the connecting disc 8 and the rotating disc 2 are connected through positioning bolts; the inner stop lever 4 on the revolving frame 3 is detachable and connected in an adjustable way. In embodiment 2, the baffle 10 is screwed with the plurality of inner bars 4 in addition to the above detachable connection. Therefore, the utility model discloses can dismantle, assemble very conveniently, such benefit reduces the space and occupies, the construction of transition of person of easy to assemble in the transportation of hoist, installation.
The utility model discloses compact structure, bearing capacity are big, can bear laying above that 3000kg rolling wire rope 5. The inner stop rods 4 can be adjusted according to the placement sizes of the inner rings of different winding steel wire ropes, and the application range is wide. Furthermore, the utility model discloses can also dismantle very conveniently, assemble, dismantle back single part weight and be no longer than 40kg, such beneficial effect is in transportation, installation, has reduced the space and has taken, and the person of facilitating the installation is in the use and the construction of transition of installation scene.
