Abstract
The utility model is related to a kind of removable pulley assembly, includes the roller of roller shaft, fastener and embedded bearing；First shaft shoulder and second shaft shoulder are sequentially provided with the axial direction of the roller shaft, and the radius of second shaft shoulder is more than first shaft shoulder；During the bearing of the roller and the hanging board of elevator are stretched into the one end of the roller shaft provided with first shaft shoulder successively from the roller side, make second shaft shoulder and the roller inconsistent, second shaft shoulder and the hanging board are inconsistent, and are locked by the fastener.The utility model changes roller again without first removing door-plate, and the door strap compared with traditional bolt-connected roller is more convenient dismounting.
Description
Technical field
The utility model is related to a kind of removable pulley assembly.
Background technology
The hanging board of elevator door now mainly has two kinds：A kind of is the axle and gantry crane hanging plate riveting of roller, separately
A kind of is the gantry crane hanging plate of detachable roller；The first, when roller needs to change, whole door guide roller component need to be dismantled and reported
It is useless, cause to waste.Especially for the door that weight is larger, such as goods elevator door and fire resistant doorsets, frictional force corresponding to guide rail is also corresponding
It can increase, the abrasion of pulley can be accelerated, replacement frequency is improved.For fire resistant doorsets, can easily it be fired mostly using polyurethane material
Burn and naked light occur, therefore many producers use teflon fire proofing instead and replace polyurethane, but this material is easy to abrasion, one
As using needing within 2~3 years to change.This changes cost for non-removable gantry crane hanging plate can be at a relatively high.Second, more
Change needs first to remove door-plate before gantry crane hanging plate, then again removes the nut of axle, extracts roller shaft out from gantry crane plate rear, can just tear open
Roller is unloaded, it is relatively time-consuming, once when door change gear is close from upper sill frame, axle will be pulled out without sufficient space.For the above
Two kinds of situations, it is desirable to which door change gear must removably simultaneously, it is necessary to change convenient.
Utility model content
To solve the above problems, the utility model provides a kind of removable pulley assembly.
To achieve the above object, the utility model provides following technical scheme：
A kind of removable pulley assembly, includes the roller of roller shaft, fastener and embedded bearing；
First shaft shoulder and second shaft shoulder are sequentially provided with the axial direction of the roller shaft, and the radius of second shaft shoulder is more than
First shaft shoulder；The roller is stretched into the one end of the roller shaft provided with first shaft shoulder successively from the roller side
In the hanging board of bearing and elevator, make second shaft shoulder and the roller inconsistent, second shaft shoulder and the hanging
Plate is inconsistent, and is locked by the fastener.
It is preferred that, also including the axle sleeve for being arranged between the bearing and the hanging board, avoid the roller
Hanging board interference rotation.
It is preferred that, the fastener is nut, also including the bullet for being arranged between the hanging board and the nut
Spring packing ring, to ensure the locking of the nut.
It is preferred that, the one end of the roller shaft provided with first shaft shoulder is provided with interior hexagonal groove, will pass through interior hexagonal
The fixed roller shaft of spoon.
The removable pulley assembly that the utility model is provided changes roller again without first removing door-plate, compared with traditional bolt
The more convenient dismounting of the door strap of connecting-type roller.
Brief description of the drawings
Fig. 1 is the utility model example structure schematic diagram；
Fig. 2 is the utility model embodiment explosive view.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment
As shown in Fig. 1~Fig. 2, a kind of removable pulley assembly, including roller shaft 1, fastener 2 and embedded bearing 31
Roller 3；
It is sequentially provided with first shaft shoulder 11 and second shaft shoulder 12 in the axial direction of the roller shaft 1, and second shaft shoulder 12
Radius is more than first shaft shoulder 11；The roller shaft 1 provided with first shaft shoulder 11 one end from the side of roller 3 successively
Stretch into the bearing 31 of the roller 3 and the hanging board 100 of elevator, the position that roller shaft 1 is installed in hanging board 100 is opening
U-shaped opening structure directed downwardly, makes second shaft shoulder 12 and the roller 3 inconsistent, second shaft shoulder 12 and the hanging
Plate 100 is inconsistent, and is locked by fastener 2.
As the improvement of above-described embodiment scheme, also including for be arranged on the bearing 31 and the hanging board 100 it
Between axle sleeve 32, the roller 3 is avoided the interference rotation of hanging plate 100.
In above-described embodiment scheme, fastener 2 uses nut, also including for be arranged on the hanging board 100 with it is described
Spring washer 21 between nut, to ensure the locking of the nut.
As the improvement of above-described embodiment scheme, the one end of the roller shaft provided with first shaft shoulder is recessed provided with interior hexagonal
Groove, the roller shaft is fixed will pass through interior Allen key.
When change gear need to be dismantled, only a wherein stopping means need to first be removed, then door-plate is tilted and extracted out, passes through pine
Open after nut, obliquely pull out roller 3, realize dismounting.New roller 3 is inserted obliquely afterwards and installs and is locked.
So operation completes the replacing of 2n door roller of n fan doors.The convenience and efficiency of Engineering operation can be preferably improved, dimension is saved
Guarantor's time and cost.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
