Description
Technical field
The present invention relates to a kind of integral type worm gear damping type slew gear and its assembly method, especially a kind of big flow electricity
Integral type worm gear damping type slew gear and its assembly method in dynamic fire monitor.
Background technology
Fire monitor is the important fire-fighting equipment to fight a fire at a distance, generally refers to the water spray that spray flow is more than 16L/s
Fire-extinguishing apparatus, including automatic type and fixed.Automatic type fire monitor is mainly by infrared electronic technology, signal transacting and the skill that communicates
The advanced technology of the subjects such as art, computer technology is combined, to fiery residence occur, system start, start and continue sprinkling fire with
And intelligence stops the processes such as water spray and controlled comprehensively.It belongs to active fire-sprinkling system, its flow 20-40L/s it
Between, range is up to 50-70 rice.Fixed fire monitor needs artificial judgment and operation, belongs to type hand fire-sprinkling system, can
According to fiery residence site specific, make and targetedly handling, its range of flow is also bigger than automatic type fire monitor, domestic at present
For fire monitor range of flow mainly between 40-200L/s, range can reach 40-130 rice.Fixed fire monitor large space
Fire extinguishing system design is the position of the hot issue in current structural fire protection field, traditional fire hydrant hydraulic giant operating distance or fire hydrant
The limitation put so that the range of fire-fighting lance does not reach the requirement of fire-fighting fire extinguishing.At this moment, fixed fire water monitor is because of its big flow
Turn into the main fire-extinguishing apparatus of large space with Far Range.It can be seen that fixed fire monitor is the fire that disappears indoors in fire-fighting system
System and the important supplement of automatic sprinkler system are tied, together constitutes indoor fire extinguishing system；Automatic type fire monitor has solid
Shape the flow and range of fire monitor, so, it is fully able to play the effect of fixed fire monitor indoors in fire-fighting system.Mesh
Preceding fire monitor still belongs to the new product of comparison in fire-fighting equipment field, and it has stream for traditional hydrant system
The advantage of amount, range etc., but there is also some defects, for example, cost is higher, species is few, market acceptance is not also high
Deng.In a word, fire monitor fire extinguishing system has adapted to the demand of modern fire just, and its application prospect is boundless.
Fire monitor is by big gun head and controlled motor, barrel, gun platform, slew gear and luffing mechanism and its control system group
Into.Wherein slew gear and luffing mechanism have identical operation principle, and most of transmission mechanism uses Worm Wheel System.Return
Rotation mechanism and luffing mechanism are critical piece, have direct influence to the performance of fire monitor.When fire monitor works, big
Inevitably there is the influence of pressure oscillation, and water hammering for the change of liquid injection direction and liquid internal under flow
Under, fire monitor can bear larger vibration, if now this vibration is acted directly on motor shaft, motor can be caused can not
Inverse damage, influences motor performance.The type of fire monitor is many on current market, and rotating part is passed using worm and gear mostly
It is dynamic, motor direct-drive worm screw, the gyration of barrel is directly driven by Worm Wheel System.Fire monitor is in gyration
Probably due to the influence of water flow jet produces some vibrations.When in fire monitor turning course if when running into larger resistance, the resistance
Power can directly act on motor shaft by worm gear structure, if resistance is excessive, motor can not drive the rotation of barrel, it will
Cause motor to suppress to turn, so as to cause motor feels hot excessive, the damage of motor can be also caused when serious.Worm gear and fire monitor at present
Barrel it is separately manufactured, be fixed together using similar to close-fitting mode, enable worm gear to drive fire monitor barrel to turn
It is dynamic.Worm gear is fastened on barrel by adaptation mostly, and this fixed form undoubtedly adds assembling difficulty, and both are matched somebody with somebody
Closing precision has larger requirement.Or worm gear is connected with barrel by holding screw, knot of this fixed form to worm gear
Structure has carried out certain destruction, the service behaviour of worm gear may have been influenceed, cause service life to shorten.Also have in addition logical
Worm gear is connected by the nipple for crossing steel part with fire-fighting monitor body by the form of non-solder, virtually adds the possibility of leakage
Property.This shortcoming is more obvious in the case of big flow 40L-200L/s, and the possibility of liquid leakage is bigger during big flow.This
Require fire monitor effectively to absorb vibration at work and effectively solve fluid leakage problems.
The related Curve guide impeller of fire monitor slewing mechanism has：Patent No. CN202554791U, utility model patent《A kind of snail
The fire monitor slewing mechanism that worm and gear rotates》Disclose a kind of method that worm gear and barrel are connected using worm gear seat, but worm gear
Although being connected between worm gear seat using bearing pin, between worm gear seat and barrel equally using it is a kind of be adapted to fastening by the way of,
One side precision is difficult to ensure that, on the other hand adds an installation step；Patent No. CN202289277U, utility model patent
《A kind of Novel fire monitor slewing mechanism》A kind of structure by bearing instead of steel ball is disclosed, and adds outer casing section
Point, it is excessively huge to cause the volume of slew gear, and steel ball is replaced using bearing additionally, due in patent, increases and assembles hardly possible
Degree, while cost is had a certain degree of increase；Patent No. CN204684519U, utility model patent《A kind of fire water monitor
Rotation transmission device》Disclose a kind of using worm screw, the fire monitor rotation transmission device formed with cone tooth worm gear and ring gear.
Ring gear is rigidly connected with fire water monitor barrel by fastening bolt.The structure of worm gear is destroyed, is had to service life necessarily
Influence, while motor can not be protected.
