Description
Technical field
The utility model belongs to the multi-rope friction hoisting machine technical field of mine industry, more particularly to a kind of for restricting more
The compound polyurethane material tail rope anticollision wheel of friction type winder.
Background technology
Field is exploited in deep well in mine, multi-rope friction hoisting machine is used for the lifting and decentralization of raw coal, personnel and material,
General operation height is 300-1000 rice or so, and the multi-rope friction hoisting machine speed of service is according to its well head condition and status of equipment
The m/s of generally 6.5m/s ~ 13, the cycle of operation is short, and operating efficiency is high, and it, which relies primarily on the main boom hoist cable of master rotor, realizes and carry
Rise, main boom hoist cable lower end is configured with counterweight armored rope, i.e. balance tail rope.Because well head depth is big, geological conditions, equipment peace
The various factors reasons such as dress, tail rope can be caused to occur to swing laterally in the process of running and cause to collide between tail rope,
Abrasion, tear, therefore installation tail rope anti-collision protection device is needed in tail rope end.
At present, the measure that domestic manufacturer takes for tail rope anticollision is most of using single shaft steel pipe, single shaft plastic tube
Or protected using sleeper, and single shaft steel pipe or single shaft plastic tube are that face contacts friction with tail rope, its rotating property is poor, once certain
The abrasion at individual position is more than other positions, then rotation beat occurs, beat is bigger, and rotation is poorer, and it is straight to be finally stopped rotation
To wear damage, its service life is typically at 7-10 days；And sleeper protects, then belong to passive protection, effect is worse.
The content of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide one kind and is used for multi-rope friction type
The compound polyurethane material tail rope anticollision wheel of elevator.
In order to realize foregoing invention purpose, the utility model uses technical scheme as described below：
A kind of compound polyurethane material tail rope anticollision wheel for multi-rope friction hoisting machine, including mandrel, roll body, roller
Set, bearing and end cap, mandrel are arranged on inside roll body by bearing, and roller set is sleeved on the outer surface of roll body, at roll body both ends
End cap is connected with mouthful, the step surface of annular is offered on the madial wall of roll body two-port, end cap is in step-like cylinder, end cap
One end stretch into roll body, the step surface on end cap is corresponding with the end face of roll body, and step surface on end cap and roll body
Weld end face.
Further, the external diameter of the step surface on end cap and the external diameter of roll body are equal.
Further, the bearing is provided with four, and four bearing spacers are uniformly sleeved on mandrel.
Further, it is provided with mounting plane on the external peripheral surface at mandrel both ends.
Further, the mandrel is metal material.
Further, the roller set is to be detachably connected with roll body.
Because using above-mentioned technical proposal, the utility model has following superiority：
1st, the utility model reasonable layout position of bearings, improves mandrel by setting evenly spaced multiple bearings
Support strength so that carrying roller is more uniformly stressed.
2nd, by setting end cap, and cause the end face welding of the step surface and roll body on end cap, on the one hand ensure that close
Effect is sealed, on the other hand make it that connecting node is more reasonable, bonding strength greatly improves, while production qualification rate is carried significantly
It is high.

Fig. 2 is Fig. 1 sectional views of the present utility model；
In figure：1st, mandrel；2nd, end cap；3rd, roll body；4th, roller set；5th, bearing.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described in detail to the technical solution of the utility model.
As shown in Figure 1, 2, a kind of compound polyurethane material tail rope anticollision wheel for multi-rope friction hoisting machine, including core
Axle 1, roll body 3, roller set 4, bearing 5 and end cap 2, mandrel 1 are metal material, and mandrel 1 is arranged on inside roll body 3 by bearing 5, roller
Set 4 is sleeved on the outer surface of roll body 3, and end cap 2 is connected with the two-port of roll body 3, is opened up on the madial wall of the two-port of roll body 3
There is the step surface of annular, end cap 2 is in step-like cylinder, and one end of end cap 2 is stretched into roll body 3, step surface and roller on end cap 2
The end face of body 3 is corresponding, and the end face of the step surface on end cap 2 and roll body 3 is welded.
In the present embodiment, the external diameter of the step surface on end cap 2 is equal with the external diameter of roll body 3.
As the preferred of the present embodiment, the bearing 5 is provided with four, and four bearings 5, which are spaced, to be uniformly sleeved on mandrel.
The bearing 5 preferentially uses the hermetically sealed bearing of roller.
In addition, in other embodiments, according to the length of actual mandrel 1, can select 6,8 bearings be used for supporting-core
Axle 1.
For the ease of installation, mounting plane is provided with the external peripheral surface at the both ends of mandrel 1, and mounting plane is set
Two are equipped with, two mounting planes are symmetrical.
To be changed for the ease of the maintenance in later stage, the roller set 4 is to be detachably connected with roll body 3, during later stage use,
After if roller set serious wear is scrapped, roller set is pulled down from roll body and more renewed.
The utility model has the advantages of following several respects compared with existing carrying roller：
On the one hand, the utility model reasonable layout position of bearings, improves core by setting evenly spaced multiple bearings
The support strength of axle so that carrying roller is more uniformly stressed.
On the other hand, by setting end cap, and the end face welding of the step surface and roll body on end cap make it that, compared to biography
The idler structure of system, the utility model connecting node is more reasonable, and bonding strength greatly improves, while make it that production qualification rate is big
It is big to improve.
Further, mandrel is connected by bearing with roll body, and roll body and roller set thereon rotate flexible, and roller set is that tail rope contacts
During be linear contact lay, frictional force substantially reduces, and in actual use, the service life of the utility model anticollision wheel was at two months
More than.
