Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
As shown in Figures 1 to 5, a kind of abrasion self-test elevator traction sheave, including interior wheel body 1 and coaxial sleeve are set in described
Outer rim 2 outside wheel body 2,2 peripheral side of outer rim are equipped with rope groove 3, are equipped with rubber pad 6, the rubber in the rope groove 3
Pad 6 is equipped with the opening 61 cooperated with wirerope diameter.Rubber pad 6 had both increased the coefficient of friction between traction sheave and wirerope,
The mutual abrasion between traction sheave and wirerope is alleviated again, while 6 wearability of rubber pad is good, it is at low cost.It is set in the rope groove 3
There is the rubber pad mounting groove for accommodating the rubber pad 6, rubber pad 6 is mounted in rubber pad mounting groove, avoids rubber pad 6 from rope groove
It falls off in 3.
3 bottom of rope groove is located at the opening 61 and is arranged right below an annular detection slot, sets in the annular detection slot
There is height to be lower than the abrasion detection pad 62 of 3 slot bottom of rope groove, is equipped with several pressure detectors 63 in the abrasion detection pad 62.
When rope groove is not worn, hoist ropes is supported by slot bottom, even if rubber pad 6 is slightly recessed into annular detection slot due to elastic reaction
It falls into, but since slot bottom and abrasion detection pad 62 have certain compartment distance, so wirerope will not touch abrasion detection pad
62.Only when 3 bottom of rope groove is worn to a certain degree, wirerope sink to can just connect to a certain degree with abrasion detection pad 62
Touching, to trigger pressure detector 63, pressure detector 63 sends signal to electric life controller to inform that staff is right in time
Traction sheave maintenance or replacement.
It is described annular detection slot cross section be it is inverted trapezoidal, which is conducive to slot bottom supporting steel-cable, so that steel
Cord can slowly decline when slot bottom is worn.
2 inner circumferential side of outer rim along being axially arranged with several retention beads 21, interior 1 peripheral side of wheel body be equipped with it is several with
The limiting slot 11 that the retention bead 21 is used cooperatively.The outer rim 2 includes the first foreign steamer half-turn 22 and the second foreign steamer half-turn
23, the axial one end of the first foreign steamer half-turn 22 is equipped with the first link block 4 with 23 junction of the second foreign steamer half-turn, described
The axial one end of second foreign steamer half-turn 23 is equipped with the second link block 5, first connection with 22 junction of the first foreign steamer half-turn
Block 4 is bolted with second link block 5.
When installation, the retention bead 21 of the first foreign steamer half-turn 22 is axially inserted into the limiting slot 11 of interior wheel body 1, then by second
The retention bead 21 of foreign steamer half-turn 23 is axially inserted into the limiting slot 11 of interior wheel body 1, finally by the first link block 4 and the second link block
5 are bolted.Traction sheave is divided into interior wheel body 1 and outer rim 2, when rope groove 3 is worn, it is only necessary to replace outer rim 2 i.e.
Can, maintenance cost is reduced, outer rim 2 is formed by connecting by the first foreign steamer half-turn 22 and the second foreign steamer half-turn 23, dimension easy to disassemble
It repairs.
First link block, 4 part is located at interior 1 axial end portion of wheel body, and 5 part of the second link block is located at institute
State interior 1 axial end portion of wheel body.The structure can avoid in traction sheave use process, and interior wheel body 1 and outer rim 2 occur axially displaced.
2 axial ends of outer rim is equipped with limit baffle ring 24, can avoid wirerope and skids off from rope groove 3.
First link block 4 is equipped at least two connecting holes, and second link block 5 is equipped at least two butt holes,
The connecting hole and the butt hole correspond.That is the first link block 4 and the second link block 5 are solid at least through two bolts
It is fixed, and at least there are two the installation direction of bolt on the contrary, the first link block 4 and the connection of the second link block 5 can be improved in the structure
Firmness.
The axial other end of the first foreign steamer half-turn 22 is equipped with rotation type limiting bar 7, when the first link block 4 is connect with second
After block 5 is bolted, it is rotated further by gag lever post 7, so that the axial other end of interior wheel body 1 is blocked in the free end of gag lever post 7,
Interior wheel body 1 and outer rim 2 is further prevented to occur in traction sheave operation axially displaced.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical new to this
The conception and scope of type is defined.Without departing from the design concept of the present utility model, ordinary people in the field is to this
