Description
Technical field
The utility model belongs to hoist engine technical field, and in particular to a kind of mine hoist engine shaft coupling auxiliary braking dress
It sets.
Background technique
Hoist engine, which is motor, drives wire rope drum through speed reducer, and folding and unfolding wirerope passes through different pulleys and changes direction.
Technique requires to be mainly drum rotation speed, that is, wirerope movement velocity and braking system security reliability.
Reel is braked using set disk brake with hoist engine in mine, and braking process is that disk type gate brake drum is first
Spool spindle is stagnated, the braking of planet-gear speed reducer and direct current generator is completed by gear coupling, pin coupler.System
The axial torque that dynamic process generates is bigger, and planetary transmission and direct current generator is made to generate biggish impact force, speed changer
Vibration is obvious, service life declines, and needs frequent shutdown maintenance, this not only affects the normal operation of lifting system, Er Qieying
The normal production of mine is rung.
Utility model content
The utility model solves the deficiencies in the prior art, provides the long mine of a kind of good braking effect, structural life-time and uses
Hoist engine.
The technical scheme adopted by the utility model is a kind of mine hoist engine shaft coupling complemental brake system, including
Pedestal, motor, retarder, the reel set gradually on the pedestal from left to right, the reel includes cable drum and steel
The symmetrically arranged brake system in cord reel both ends, the pedestal side are additionally provided with hydraulic system, and the hydraulic system with
The brake system is connected by pressure piping, and shaft coupling, described shaft coupling one end are provided between the motor and retarder
It is provided with hold-fast body.
Preferably, the hold-fast body is fluid pressure type, and the hold-fast body includes semicircle holding watt, described to hold a watt set tightly
Set on shaft coupling lower end side, the holding watt lower end is provided with hydraulic jack, and the hydraulic jack passes through with hydraulic system
Pressure piping is connected.
Preferably, the brake system includes being fixed on the symmetrically arranged brake disc in cable drum both ends and being arranged in brake
Brake block mechanism on hull, the brake block mechanism is connected by pressure piping with hydraulic system, and the brake block mechanism
It is fixed on the pedestal.
Compared to the prior art, the utility model, which has the advantages that, increases braking by the hold-fast body of setting
Torque, while the inertia impact to retarder and motor is reduced, but also extend the service life of retarder and motor.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model hold-fast body structural schematic diagram；
Fig. 3 is the utility model reel structure schematic diagram.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of mine hoist engine shaft coupling complemental brake system, refering to fig. 1, including pedestal 1, from a left side on the pedestal 1
Motor 6, retarder 3, the reel 2 set gradually to the right, the reel 2 include 21 both ends of cable drum 21 and cable drum
Symmetrically arranged brake system 22,1 side of pedestal are additionally provided with hydraulic system 7, and the hydraulic system 7 and the brake
System 22 is connected by pressure piping, shaft coupling 4 is provided between the motor 6 and retarder 3, described 4 one end of shaft coupling is set
It is equipped with hold-fast body 5.The effect of the hold-fast body 5 is locking shaft coupling 4, makes 3 ramp to stop of motor 6 and retarder.
In order to improve braking effect, referring to Fig.2, the hold-fast body 5 is fluid pressure type, the hold-fast body 5 includes semicircle
Shape holding watt 51, the holding watt 51 are sheathed on 4 lower end side of shaft coupling, and holding watt 51 lower ends are provided with hydraulic jack
52, the hydraulic jack 52 is connected with hydraulic system 7 by pressure piping.
Refering to Fig. 3, the brake system 22 includes being fixed on symmetrically arranged 221 He of brake disc in 21 both ends of cable drum
The brake block mechanism 222 being arranged on brake disc 221, the brake block mechanism 222 pass through pressure piping and 7 phase of hydraulic system
Even, and the brake block mechanism 222 is fixed on the pedestal 1.
Operation principles: when cable drum 21 needs to stop, brake system 22 just be will start, and reel 2 stops at once, so
And due to the inertia of motor 6, motor 6 can generate the inertia force of a moment, this inertia force can be transmitted to gearbox 3, speed change
Case 3 is transmitted on reel 2, however reel 2 has stopped operating, so gearbox 3 is also required to stop operating, so inertia force meeting
Very big impact is generated to gearbox 3 and transmission shaft, accelerates the damage of gearbox 3 and transmission shaft, when setting is embraced on shaft coupling 4
Tight mechanism 5, when brake system 22 starts, while hold-fast body 5 also generates active force simultaneously, prevents to generate on motor 6 used
Property power be transmitted on gearbox 3 and the subsequent transmission shaft of motor 6, the braking effect that has successively reached and extending structure use the longevity
Life.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
