Description
Technical Field
The invention relates to the technical field of power equipment, in particular to an inner ring bearing type belt pulley.
Background
FIG. 1 is a schematic illustration of a portion of a wire broken between two towers.
Referring to fig. 1, there are often a plurality of wires between the first tower 1 and the first tower 2, and due to aging or impact damage, some wires may be broken to form broken wires 3, while unbroken wires 4 are still erected between the two towers.
When a broken wire occurs, a new wire 5 needs to be installed between two towers to replace the broken wire, and the current method for installing the new wire 5 is as follows:
(1) removing broken wires, and arranging pulleys at the positions of the first tower 1 and the first tower 2 where the broken wires are originally arranged;
(2) one end of the new wire 5 starts from the ground of the first tower 1, passes through a pulley at the upper end of the first tower 1, returns to the ground, and is carried by a person along with the end of the new wire 5 to reach the first tower 2 from the ground; the end of the new wire 5 returns to the ground through the pulley at the upper end of the first tower 2;
(3) a mechanical device is arranged on one side of the first tower 2 far away from the first tower 1, and the mechanical device tightens the new wire 5 until the new wire 5 tightens and rises to a specified position, and enables the vertical arc to meet the requirements.
The above-mentioned operation method has the following problems:
(1) the quality of the new wire 5 is large, and the new wire 5 is difficult and laborious to walk on the ground by manpower;
(2) when the new wire 5 is tightened, the tree can block the new wire 5 from rising under the condition of crossing mountains and mountains, the situation that the new wire 5 is hung on the tree, and cannot be pulled up or put back on the ground again is difficult, and finally the whole new wire 5 is disabled.
Fig. 2 is a schematic structural view of a conventional wire harness pulley.
Referring to fig. 2, the wire pulley 6 is erected on an unbroken wire 4, then a new wire 5 is fixed on the wire pulley 6, and the wire pulley 6 slides along the unbroken wire 4 to realize aerial wiring, thereby avoiding the problem caused by ground manpower wiring. However, the existing wire trolley 6 can realize aerial wire pulling, but is easy to be blocked at the connection position 401 of the cable, so that the wire trolley 6 cannot move.
Therefore, a power device is needed, which not only can realize the aerial wiring of a new wire, but also can avoid the occurrence of a clamping at a connection position.

The mounting ring 701 includes an upper half and a lower half. The tops of the two upper semi-rings are fixedly connected through one connecting rod 8, and the bottoms of the two lower semi-rings are fixedly connected through the other connecting rod 8. Two pull rings 9 are arranged at the bottoms of the connecting rods 8 connected with the two lower semi-rings. One end of the pull rope 10 is connected with the wire collecting device 11, the other end of the pull rope is fixedly connected with one pull ring 9 of the inner ring bearing type wire carrying pulley, and the other pull ring 9 is used for fixing a new wire 5. Of course, the winding device 11 may be omitted, and the pull rope 10 may be pulled by manpower to advance the inner ring bearing type belt pulley along the unbroken wire 4. The via hole 704 and the mounting ring 701 are coaxial, and the longitudinal direction of the two connecting rods 8 is parallel to the axial direction of the mounting ring 701.
Preferably, the diameter of the via 704 is not smaller than the diameter of the unbroken cable connection location 401.
The working principle of the lead erection system provided by the embodiment is as follows:
(1) the first tower 1 is lifted, and an unbroken wire 4 passes through the wire through hole 704, so that the inner ring bearing type wire pulley is erected in the air;
(2) one end of a new wire 5 is fixed on the other pull ring 9;
(3) fixing the wire collecting device 11 on one side of the second tower 2 far away from the first tower 1, and then starting the wire collecting device 11;
(4) the stay cord 10 pulls the inner ring bearing type belt pulley to move from the upper part of the first pole tower 1 to the upper part of the second pole tower 2 along the unbroken wire 4, and simultaneously pulls the new wire 5 to move in the air, and the new wire 5 is fixed on the second pole tower 2.
The inner ring bearing type belt line pulley and the lead erection system provided by the embodiment have the following advantages:
(1) the new wire 5 does not need to be dragged to walk on the ground, so that the labor is saved;
(2) the lifting wire is not needed, so that sundries such as branches and the like are prevented from obstructing the lifting of the new wire 5;
(3) when the inner ring bearing type belt pulley advances to the connection position 401 of the unbroken wire 4, the connection position 401 can be fed into the wire passing hole 704 under the action of the bearing 703 because the connection position 401 encounters the rolling bearing 703, so that the condition that the connection position 401 stops the inner ring bearing type belt pulley from advancing is avoided.
In this embodiment, the upper half ring includes a semi-annular upper fixing layer 7011, the upper fixing layer 7011 is provided with a plurality of upper shaft grooves around the axis of the mounting ring 701, and a part of the rotating shaft 702 is fixed in the upper shaft grooves. One end of the lower semi-ring is rotationally connected with the upper semi-ring, and the other end of the lower semi-ring is connected with the upper semi-ring in an openable and closable manner; the lower half ring comprises a semi-annular lower fixing layer 7013, the lower fixing layer 7013 is provided with a plurality of lower shaft grooves around the axis of the mounting ring 701, and the rest of the rotating shafts 702 are fixed in the lower shaft grooves. The upper semi-ring further comprises two upper cover plates 7012, the upper fixing layer 7011 is located between the two upper cover plates 7012, and the upper cover plates 7012 are rotatably connected with the lower fixing layer 7013; the lower half ring further comprises two lower cover plates 7014, the lower fixing layer 7013 is located between the two lower cover plates 7014, and the lower cover plates 7014 are connected with the upper fixing layer 7011 in an openable and closable manner.
Further, the inner ring bearing type belt pulley further includes a deployment shaft 705 and a latch 706. The end part of one end of the lower fixing layer 7013, which is rotationally connected with the upper semi-ring, extends into the space between the two upper cover plates 7012; the unfolding shaft 705 penetrates and is rotatably connected to the end of the lower fixing layer 7013 extending between the two upper cover plates 7012 and the two upper cover plates 7012. The end of the upper fixing layer 7011 and the end of the lower half ring, which can be connected in an opening and closing manner, can extend into the space between the two lower cover plates 7014 and is provided with a second insertion and extraction hole, and the opening and closing bolt 706 penetrates through the first insertion and extraction hole and the second insertion and extraction hole to realize the buckling between the upper fixing layer 7011 and the lower cover plate 7014.
It can be appreciated that pulling out the latch 706 opens the two half rings, and inserts the latch 706 after the unbroken cable is placed in the wire through hole 704, thus completing the erection of the inner ring bearing type belt pulley.
The inner ring bearing type belt line pulley and the wire erection system provided by the embodiment can realize the aerial wiring of the new wire 5 and avoid the clamping at the connection position 401.
