Abstract

Seal protecting device is driven the invention discloses a kind of shield machine screw machine; including attachment means and baffle plate; the attachment means are bolted on shell ring flange, and the baffle plate is connected by rotating shaft flange by bolt and helical axis secure fit, the rotary shaft with drive device.

Description

A kind of shield machine screw machine drives seal protecting device
Technical field
The invention belongs to Tunnel Engineering technical field, it is related to one kind to slow down shield machine screw machine and drives seal protecting device.
Background technology
Shield machine is a kind of special engineering machinery of tunnel piercing, and the native stone that shield machine driving is produced is conveyed by screw machine Go out.The monolithic devices part that screw machine is made up of helical axis, drive system, shell ring etc., be shield machine core component it One, and screw machine drives sealing to be mainly used in providing good running environment for the oscillating bearing and decelerator of screw machine.It is existing Using can produce seal failure after a period of time, its reason is conveying worm:The screw design of conveying worm is pacified for cantilever Fill and there is certain angle to incline in actual use, cause the oscillating bearing in drive device to bear spiral with spiral shaft connection place Moment of flexure and the change of periodic pressure that axle gravity causes.With the abrasion of helical blade and shell ring inner headed face, dregs by The suspension support effect to helical axis is gradually lost, and then seal clearance can be caused to increase, play when helical axis is operated, mud passes through Space is poured at lip packing, makes bad seals, and reduction box enters mud, exacerbates the loss of gear oil and the mill of gear and axle sleeve Damage.
The content of the invention
In order to overcome above-mentioned deficiency of the prior art, sealing protection is driven the invention provides a kind of shield machine screw machine Device, slows down the seal failure problem that spiral shell machine actuating device causes by helical axis cantilever support, also can a certain degree of alleviation because The too fast problem of blade wear that spiral shell machine cantilever support causes.
To achieve the above object, present invention employs following technical scheme.
A kind of shield machine screw machine drives seal protecting device, including attachment means and baffle plate, and the attachment means pass through It is bolted on shell ring flange, by bolt and helical axis secure fit, the helical axis is by rotating method of principal axes for the baffle plate Orchid is connected with drive device.
Further, the baffle plate is provided with deep-slotted chip breaker.
Further, the attachment means are in contact with the deep-slotted chip breaker.
Further, the attachment means include the attachment means body of casting, and the attachment means body of casting is embedded with sleeve, sleeve inner side It is connected with the attachment means body of casting by spring, the sleeve outside is bolted wearing plate.
Further, the sleeve outer wall is provided with back-up ring with attachment means body of casting junction.
Further, the attachment means are provided with water pipe and cleaning brush with the deep-slotted chip breaker touching position.
The present invention can slow down the seal failure problem that spiral shell machine actuating device causes by helical axis cantilever support, also can be certain The alleviation of degree is because of the too fast problem of blade wear that spiral shell machine cantilever support causes.

In figure, 1. attachment means, 2. baffle plate, 3. shell ring flange, 4. spiral shaft flange, 5. helical axis, 6. drive device, The 41. attachment means body of castings, 42. springs, 43. sleeves, 44. bolts, 45. wearing plates, 46. back-up rings.
Specific embodiment
Implementation of the invention is described in detail below in conjunction with the accompanying drawings.
As shown in figures 1 to 6, a kind of shield machine screw machine drives seal protecting device, including attachment means 1 and baffle plate 2, institute State attachment means 1 to be bolted on shell ring flange 2, the baffle plate 2 is described by bolt and the secure fit of helical axis 5 Helical axis 5 is connected by rotating shaft flange 4 with drive device 6.The baffle plate 2 is provided with deep-slotted chip breaker, attachment means 1 and the arc Groove is in contact.
The attachment means 1 include the attachment means body of casting 41, and the attachment means body of casting 41 is embedded with sleeve 43, the inner side of sleeve 43 It is connected with the attachment means body of casting 41 by spring 42, wearing plate 45, the sleeve are fixed in the outside of the sleeve 43 by bolt 44 43 outer walls are provided with back-up ring 46 with the junction of the attachment means body of casting 41.
More excellent, attachment means 1 are provided with water pipe and cleaning brush with the deep-slotted chip breaker touching position, are responsible for cleaning baffle plate 2 Deep-slotted chip breaker.
The opposite force that the present apparatus is provided with the connecting bolt of shell ring, and helical axis and drive device connecting bolt active force Collective effect, offset the torque that helical axis component is produced, spiral shell machine actuating device can be slowed down because helical axis cantilever support causes Seal failure problem, also a certain degree of can alleviate the blade wear caused by spiral shell machine cantilever support too fast.The inventive structure Simply, the simple transformation in original spiral shell machine structure.
