Further, guide rod is provided in the guide groove, the spring is set on guide rod.
By using above-mentioned technical proposal, guide rod plays guiding role to spring, prevents spring deviation from leading, to ensure
Buffer function of the spring to lifting platform.
Further, it is arranged fluted on the bottom wall of the guide groove, the guide rod is arranged in groove.
By using above-mentioned technical proposal, guide rod is arranged in groove, is led so that lifting platform effectively be avoided to strike
Guide rod is caused to damage to bar, to extend the service life of Anti-over-hoisting device.
Further, the guide rod is set as camber.
By using above-mentioned technical proposal, the arc type structure of guide rod can change the elastic force direction of spring, make spring
Activity direction of the action direction of power always perpendicular to lifting platform.
Further, increasing is provided on the inner sidewall of the guide groove to rub pad.
By using above-mentioned technical proposal, the coefficient of friction between guide groove and lifting platform is improved, to further increase
Decelerating effect of the guide pad to lifting platform.
Further, the increasing, which rubs, is provided with increasing on pad and rubs burr.
By using above-mentioned technical proposal, the coefficient of friction between guide groove and lifting platform is further improved, is reached
Lifting platform is reduced to rush to summit the effect of speed.
In conclusion the utility model has the following beneficial effects:
1, by the way that guide pad is arranged in frame top, to achieve the effect that preventing lifting platform from rushing to summit falls；
2, by the way that resilient snubber is arranged in guide groove, the speed of rushing to summit of lifting platform can be reduced, to be effectively reduced
The case where lifting platform is stuck between guide pad appearance；
3, increase the pad that rubs by being arranged in guide groove, there is the speed of rushing to summit that can reduce lifting platform, protect lifting platform
Effect.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
Embodiment:
A kind of preventing colliding with top drop device, referring to Fig.1 comprising rack 1, rack 1 include two in the side plate being oppositely arranged
2, lifting platform 4 is provided between two side plates 2, and the sliding slot 21 slided up and down for lifting platform 4 is provided on two side plates 2.Side
2 bottom of plate has been wholely set guide pad 3, and two guide pads 3 are in that the side wall being oppositely arranged is disposed as camber, and concave surface is towards liter
Platform 4 is dropped, and offers the guide groove 31 communicated with sliding slot 21 on the side wall of camber setting.The contact of guide pad 3 and lifting platform 4
The radian in face is smaller, can reduce lifting platform 4 and the stuck risk of guide pad 3.21 guide pad is risen to along the chute in lifting platform 4
When 3 bottom end, the arc type structure of guide pad 3 can play the role of limit to lifting platform 4, and lifting platform 4 more rises, and 3 pairs of guide pad rise
The resistance for dropping platform 4 is bigger, so that the rate of climb of lifting platform 4 is slowly reduced, until lifting platform 4 stops.
Referring to Figures 1 and 2, fluted 34 are opened up on the bottom wall of guide groove 31, guide rod 33 is fixed in groove 34, are oriented to
Bar 33 is set as camber and fixes along the extending direction of guide groove 31.Spring 32,32 both ends of spring point are arranged on guide rod 33
It is not fixed on two end faces of groove 34,32 part of spring is exposed groove 34 and can be contacted with lifting platform 4.It is rigid in lifting platform 4
When rising to guide groove 31, spring 32 is contacted with lifting platform 4, and during lifting platform 4 continues rising, spring 32 due to
Deformation occurs for the effect of lifting platform 4, to have the active force for preventing it from rising to lifting platform 4, slows down the rising of lifting platform 4
Speed, until lifting platform 4 stop.
Referring to Figures 1 and 2, it rubs pad 35 in being provided with increasing on two inner sidewalls being oppositely arranged in guide groove 31, increasing rubs pad
Increasing is provided on 35 to rub burr 36.During lifting platform 4 rises, increasing rubs pad 35 and increasing rubs, and burr 36 has one to lifting platform 4
It is a to move contrary frictional force, thus the rate of climb of the lifting platform 4 slowed down.
Working principle is as follows:
In the uphill process of lifting platform 4, lifting platform 4 enters in guide groove 31 along sliding slot 21, in the guide pad 3 of camber
There is a downward active force to lifting platform 4,4 rate of climb of lifting platform slows down.Due to the contact surface of guide pad 3 and lifting platform 4
Radian it is smaller, smaller to the active force of lifting platform 4, spring 32 can reduce the rate of climb of lifting platform 4 at this time.In lifting platform
During 4 continue rising, deformation occurs for spring 32, there is downward active force to lifting platform 4, at the same increase rub pad 35 and increasing rub it is convex
Line 36 has the active force for preventing it from advancing to lifting platform 4.Before lifting platform 4 and guide pad 3 are stuck, in a series of active forces
Under, realize the effect that lifting platform 4 gradually slows down and stops.
