Description

The gear ring type coke cutting machine

The utility model belongs to a kind of broken equipment of lump coke greatly that is used for.

The present coke disintegrating apparatus that uses, comparatively advanced is the double teeth roller coke cutting machine.Basic composition is of this coke cutting machine: discaling roll is made up of multi-edge column-shaped roller spoke and the polylith tooth plate that is fixedly mounted on this roller spoke, and the roller spoke is installed on the power transmission shaft, drives its rotation by transmission and reducing gear.What this transmission and reducing gear adopted is the carrier bar gear structure, promptly connect four gear trains and become the carrier bar gear-box with carrier bar, play the transmission decelerating effect, finish the different speed rotations of two discaling rolls and driven roll (roller at a slow speed) is moved and the purpose of regulating two discaling roll roll spacings.This coke cutting machine is compared with traditional coke cutting machine, has advantages such as coke size after rational in infrastructure, high efficiency and the fragmentation is more even, still, because its transmission and deceleration device structure more complicated, makes the entire equipment comparison heaviness that seems; Moreover because the discaling roll of this coke cutting machine is a multi-edge column-shaped, and the burnt tooth of cutting on the tooth plate is difficult to realize whole arranged radiallys, and two discaling rolls are in rotation process, the gap between them is difficult to be consistent, so make the coke size that cuts out be difficult to reach more uniform requirement.

The purpose of this utility model is to provide a kind of simple in structure, in light weight, broken coke size gear ring type coke cutting machine more uniformly.

The utility model is to realize like this, this coke cutting machine has a platform-type frame, the motor that is fixed on this frame rotates through fixed teeth roll shaft and the movable discaling roll roll shaft that decelerator drives in the discaling roll device, the fixed teeth roll shaft is installed on the fixed mounting base of frame through bearing, movable discaling roll beam warp bearing is installed on the expansion bearing seat, the expansion bearing seat is installed in the rail groove of frame, between the fixed support of expansion bearing seat and support, spring is installed, and the bolt of this spring compression degree of adjusting is installed on this fixed support.Be separately installed with one or more gear ring on fixed teeth roll shaft and movable discaling roll axle, this gear ring is separately fixed on fixed teeth roll shaft and the movable discaling roll axle through roller end circle, roller end hub, axle head circle and set bolt and constitutes.

Because the said coke cutting machine of the utility model, its discaling roll is changed into the cylin-drical tooth roll shaft of being made up of main shaft and gear ring by original multi-edge column-shaped, so just can guarantee that its two discaling roll is in rotary course, gap between the two is basic identical, the coke size that fragmentation is gone out is also more even, to be satisfied with the requirement of industry STRENGTH ON COKE granularities such as smelting iron and steel.Secondly, what the decelerator of this coke cutting machine adopted is tooth shaft type decelerator, two output shafts of decelerator are connected with two discaling roll axles on the discaling roll machine mechanism by a permanent coupling and an articulated coupling respectively, make transmission mechanism become simpler, the weight of coke cutting machine also can alleviate widely, and the power that uses also can reduce, and percentage of damage will improve, keep in repair also can be simple.

Below in conjunction with accompanying drawing the utility model is described in detail.

With reference to accompanying drawing 1,2, frame 6 is a kind of platform-type structures, and the discaling roll device 9 of motor 1, decelerator 4, broken coke just is fixed on this frame 6.Wherein, motor 1 rotates through the rotating shaft that belt drive unit 2 drives decelerator 4, and fixed teeth roll shaft 8 and movable discaling roll axle 7 that the output shaft of decelerator 4 drives in the discaling roll device 9 rotate, and fixed teeth roll shaft 8 is installed on the fixed mounting base of frame 6 through bearing.Movable discaling roll axle 7 is installed on the expansion bearing seat 10 through bearing, expansion bearing seat 10 is installed in the rail groove of frame 6, between the fixed support of the outer side frame 6 of movable supporting rack 10 spring 17 is installed, and the degree that compresses that spring 17 is installed on this fixed support is regulated bolt 22, by regulating the roll spacing that this bolt 22 can be adjusted the cutting force of the broken coke of this coke cutting machine and regulate two rollers.With reference to accompanying drawing 3, accompanying drawing 4, on fixed teeth roll shaft 8 and movable discaling roll axle 7, one or more gear ring 13 is installed respectively, have crushing teeth on the periphery of gear ring 13, the profile of tooth of this crushing teeth preferably adopts the knife-edge tooth of band sword, to guarantee that STRENGTH ON COKE is sheared effectively and the splitting fragmentation.And the crushing teeth on the gear ring 13 preferably is length and is evenly distributed on the gear ring alternately.Gear ring 13 is fixedly mounted on formation on fixed teeth roll shaft 8 and the movable discaling roll axle 7 respectively through roller end circle 20, roller end hub 21, the axle head circle 16 at two ends and the set bolt of axially installing 12.

Gear ring 13 can be made into the whole ring form structure, directly is sleeved on the discaling roll axle, also can make semicircle ring type structure, then by two semicircular ring gear rings when discaling roll is installed, be fixed into the gear ring of an integral body, the assembling of the discaling roll of being more convenient for like this.

Decelerator 4 of the present utility model can adopt the tooth-like reducing gear of traditional plate, reaches the purpose of deceleration and transferring power through gear ring gear, sleeve.The utility model also can adopt the gear shaft decelerator, with reference to accompanying drawing 5, accompanying drawing 6.Decelerator 4 has an input gear shaft 19 and at least two output shafts, and promptly axle 14 and right output shaft 15 are failed in a left side, and wherein left output shaft 14 is connected with fixed teeth roll shaft 8 through closed coupling 5; Right output shaft 15 is connected with movable discaling roll axle 7 through hinge coupling 3; The outer end of input gear shaft 19 is installed with belt pulley, constitutes belt drive unit 2 with the driving belt of installing on belt pulley on the motor 1 and two belt pulleys.

Optimum structure form as the gear shaft decelerator that the utility model adopted is: input gear shaft 19 drives left output shaft 14 through gear drive and rotates, input gear shaft 9 minor axis 18 in the middle of gear drive drives rotates, middle minor axis 18 drives right output shaft 15 through travelling gear again and rotates, guaranteed that so promptly right output shaft 15 is different with left output shaft 14 the two rotation direction, can realize that again the differential of left and right output shaft rotates.

Platform-type frame 6 of the present utility model can directly be fixedly mounted on the support.For the ease of the maintenance etc., also can be installed with wheel 11 in the lower end of platform-type frame 6, this coke cutting machine can be moved on ground or track, more convenient and flexible in application.
