It sets；It is equipped with vertical rack gear on the left of the gear wheel, the tower crane base outer wall on the left of the rack gear fixed connecting base, the rack gear
Two sides are fixed with fricting strip, and welding is equipped with gear protective cover above the gear wheel.
Preferably, the speed-limiting device is made of set axis, Telescopic Fixed pipe and telescopic piston pipe, and the set axis is consolidated with flexible
Determine pipe to be an integral molding structure, be arranged with telescopic piston pipe in the Telescopic Fixed pipe, the telescopic piston pipe end one at
Type is equipped with spherical friction piece, is equipped with spring inside the telescopic piston pipe and Telescopic Fixed pipe, the both ends of the spring respectively at
Set axis is fixedly connected with spherical friction piece；The spherical friction piece that the speed-limiting device is equipped with is no less than 10, and what is generated in this way rubs
It is bigger to wipe power, when emergency occurs, when fast and effectively elevator can be made to stop, and remain stationary, Telescopic Fixed pipe
It must not exceed the radius of gear with the total length of telescopic piston pipe, but total length is greater than the half of gear wheel when speed-limiting device work
Diameter.
Preferably, rack gear engagement connection corresponding with gear wheel, the spherical friction piece is towards fricting strip, so that institute
Spherical friction piece is stated in rotary work, rack gear will not be may wear to.
Preferably, the speed-limiting device two sides are respectively equipped with shield, and shield has and prevents gear wheel and speed-limiting device
Between gap enter the effect of broken sandstone, in order to avoid cause Caton abrased gear and speed-limiting device, and the set axis, gear wheel and
Shield is all set in gear wheel shaft and is fixedly connected.
Compared with prior art, the utility model has the beneficial effects that
One, the utility model is slowed down by the way that piston telescoping tube and spring is added to realize, and overcomes bullet in conjunction with centrifugal force
It is more than the benefit that certain speed limit device just works that the pulling force of spring, which has reached revolving speed,；
Two, selected friction piece is the spherical waste in order to reduce spherical friction piece itself, and gear protective cover is set as Z
Shape pops up from shield lower right-hand side so that sandstone is fallen above left side, just sandstone will not be made to enter gear wheel and tooth in this way
The firm work of elevator is realized in gap between item；Speed-limiting device, which plays decelerating effect, lands elevator slowly steadily, makes oppressive
Member flees from carriage as early as possible.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of security protection dress of construction elevator
It sets, including elevator 1,1 side of elevator is respectively provided with two gear wheels 2 up and down, and 2 two sides of gear wheel are respectively provided with speed-limiting device A；Gear wheel
2 left sides are equipped with vertical rack gear 4, and rack gear 4 is fixedly connected on the outer wall of the tower crane base 5 in left side, and the two sides of rack gear 4, which are fixed with, rubs
Rub piece 9, welding is equipped with gear protective cover 6 above gear wheel 2.
Speed-limiting device A is made of set axis A1, Telescopic Fixed pipe A3 and telescopic piston pipe A4, set axis A1 and Telescopic Fixed pipe A3
It is an integral molding structure, telescopic piston pipe A4 is arranged in Telescopic Fixed pipe A3, the telescopic piston end pipe A4 is integrally formed and is equipped with
Spring A2 is equipped with inside spherical friction piece 3, telescopic piston pipe A4 and Telescopic Fixed pipe A3, the both ends of spring A2 are respectively at set axis A1
It is fixedly connected with spherical friction piece 3；The spherical friction piece 3 that speed-limiting device A is equipped with is no less than 9, and when remaining stationary, and stretches solid
The total length for determining pipe A3 and telescopic piston pipe A4 must not exceed the radius of gear.
The engagement connection corresponding with gear wheel 2 of rack gear 4, spherical friction piece 3 are corresponded towards fricting strip 9 so that spherical
Friction piece 3 will not wear rack gear 4 at work.
The two sides speed-limiting device A are respectively equipped with shield 8, prevent broken sandstone from two sides enter speed-limiting device A and gear wheel 2 it
Between gap cause card to stop, and cover axis A1, gear wheel 2 and be all set in gear wheel shaft 7 and be fixedly connected with shield 8.
Working principle: the carriage and drive system of elevator 1 are installed on the guide rail and frame of elevator, and this programme is existing
There is increased protective device on the basis of elevator device, wherein elevator 1 at the uniform velocity and is not above gear wheel 2 on tower crane base 5
When rated speed, due to the pulling force effect of spring A2,3 times of telescopic piston pipe A4 and spherical friction piece inwardly tighten, speed-limiting device A
It does not work；It drops suddenly during elevator 1 is mobile on tower crane base 5,2 revolving speed of gear wheel is too fast, and gear wheel shaft 7 drives
Speed-limiting device A rotation is too fast, and since centrifugal force acts on, spring A2, which is pulled outwardly, to be stretched, and telescopic piston pipe A4 is expanded outwardly, spherical to rub
Rub body 3 is thrown out of, and spherical friction piece 3 is contacted with the fricting strip 9 of 4 two sides of rack gear, is slowed down by frictional force, guarantees that elevator 1 is steady
Underground is fallen to the ground, and reduces impact force.
