Description
Technical field
The present invention relates to the technical field of cage guide vibration damping, especially a kind of rail module with vibration-damping function.
Background technology
Cage guide is the elevator structures being made up of rail and connecting plate, and it is divided into car guide rail and counter weight guide track.Guide rail
While playing the guiding role, also subject to impulsive force when car and elevator brake etc..
Generally, the distance of adjacent rails support is 2.5m, to produce vibration, amplitude when boots relative motion on guide rail is led
Maximum is the centre position of adjacent stent.However, the damped coefficient of existing majority cage guide is relatively low, vibration is obvious, shakes
Larger.
Content of the invention
The technical problem to be solved in the present invention is：In order to overcome the deficiencies in the prior art, provide a kind of have subtract
The rail module of function of shaking, reduces peak swing, reaches effectiveness in vibration suppression.
The technical solution adopted for the present invention to solve the technical problems is：A kind of rail module with vibration-damping function, bag
The guide rail of T font is included, the back side of guide rail is provided with the absorbing amortisseur bar that goes up along its length, the centre position of absorbing amortisseur bar
Place opens up jagged；The back side of guide rail is also equipped with the dynamic absorber mechanism according to its first natural frequency, dynamic absorber mechanism
Mainly it is made up of L bracket, vibration absorbing spring and absorbing mass, L bracket is embedded in breach and is fixed on the back side of guide rail,
Absorbing mass is placed on the crossbeam of L bracket, and one end of vibration absorbing spring is connected with the longeron of L bracket, vibration absorbing spring
The other end be connected with absorbing mass.
Limit further, absorbing amortisseur bar described in technique scheme is made up of rubber.
Limit further, described in technique scheme, vibration absorbing spring uses extension spring.
Limit further, absorbing amortisseur bar described in technique scheme is fastened on by several bolts and several nuts
The back side of guide rail.
Limit further, L bracket described in technique scheme is fastened on by several bolts and several nuts and leads
The back side of rail.
Limit further, the bottom of absorbing mass described in technique scheme is provided with several scroll wheels.
The invention has the beneficial effects as follows：The rail module has advantages below：
First, pass through to increase absorbing amortisseur bar at the back side of guide rail, the damped coefficient of guide rail can be effectively increased, be reduced maximum and shake
Width；
2nd, according to the first natural frequency of guide rail, increase dynamic absorber mechanism in the middle position of rail back, that is, exist
Rail back increases mass spring resonance system, and thus decay guide rail is reached due to leading the single order vibration that boots impact shock causes
Effectiveness in vibration suppression.
Description of the drawings

Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples, the composition represented by example below whole in
Appearance is not limited to necessary to the solution as the invention described in claim.
See Fig. 1 and Fig. 2, a kind of rail module with vibration-damping function, including the guide rail 1 of T font, the back side peace of guide rail 1
Equipped with the absorbing amortisseur bar 2 that goes up along its length, absorbing amortisseur bar 2 is made up of rubber.Absorbing amortisseur bar 2 is by several bolts
6 back sides for being fastened on guide rail 1 with several nuts 7, bolt 6 uses hex bolts, and nut 7 uses hex nut.
By increasing absorbing amortisseur bar 2 at the back side of guide rail 1, the damped coefficient of guide rail 1 can be effectively increased, reduce peak swing.
The middle position of absorbing amortisseur bar 2 opens up jagged；The back side of guide rail 1 is also equipped with according to the intrinsic frequency of its single order
The dynamic absorber mechanism of rate, dynamic absorber mechanism is mainly made up of L bracket 3, vibration absorbing spring 4 and absorbing mass 5, absorbing bullet
Spring 4 uses extension spring, and the bottom of absorbing mass 5 is provided with several scroll wheels 8.L bracket 3 is embedded in breach and solid
The back side of guide rail 1 is scheduled on, L bracket 3 is fastened on the back side of guide rail 1 by several bolts 6 and several nuts 7.Absorbing quality
Block 5 is placed on the crossbeam of L bracket 3, and one end of vibration absorbing spring 4 is connected with the longeron of L bracket 3, vibration absorbing spring 4 another
One end is connected with absorbing mass 5.Cage guide for different model can select different vibration absorbing spring 4 and different
Absorbing mass 5 constitutes a series of guide rail vibration modules.According to the first natural frequency of guide rail 1, in the interposition at 1 back side of guide rail
