Abstract
The utility model relates to a centrifugal speed limiter, which comprises a box cover, a box, a wheel core and two or more hinge pins, wherein the hinge pins surround the wheel core to form a circle. The centrifugal speed limiter is characterized in that a flail block is connected onto each of the hinge pins, one end of each flail block is hinged with the corresponding hinge pin, and the other end of each flail block is fixedly connected with a single block which contacts with the inner wall of the box in a sliding manner. The single block directly contacts with the inner wall of the box so as to be directly detached and replaced when abraded, and the centrifugal speed limiter is convenient in installation and saves cost.
Description
Technical field
The utility model relates to a kind of centrifugal speed limiter, belongs to the gate field.
Background technique
Centrifugal speed limiter has played the speed limit effect in gate decline process, has in time protected gate.At present, the piece that gets rid of in centrifugal speed limiter is an integral body, in gate decline process, gets rid of piece and cabinet wall rubs, because fast rotational, friction level is very big, will get rid of the piece wearing and tearing easily, when maintenance or changing, the whole piece that gets rid of must be removed and changed, increased cost.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of centrifugal speed limiter, comprise case lid, casing, core wheel and the bearing pin more than 2 or 2, the center of circle, cross section of described bearing pin is circular around the center of circle, cross section of core wheel, it is characterized in that: on described a plurality of bearing pins, respectively connect and get rid of piece, a described end and the bearing pin that gets rid of piece is hinged, and the described the other end that gets rid of piece is fixedlyed connected with a monolithic, described monolithic and described cabinet wall sliding contact.
The described piece that gets rid of is connected by a bolt with described monolithic.
A kind of centrifugal speed limiter that the utility model provides is directly contacted with cabinet wall by monolithic, when monolithic is worn, can directly monolithic be removed and change, and is easy for installation, also provides cost savings.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the structural representation of A-A in the utility model plan view;
Fig. 3 is the structural representation that gets rid of piece in the utility model.
Reference character: 1, case lid 2, casing 3, core wheel 4, bearing pin
5, get rid of piece 6, monolithic 7, bolt.
Embodiment
Describe technological scheme of the present invention in detail below in conjunction with accompanying drawing.
The utility model provides a kind of centrifugal speed limiter, comprise case lid 1, casing 2, core wheel 3 and the bearing pin more than 2 or 24, the center of circle, cross section of described bearing pin 4 is circular around the center of circle, cross section of core wheel 3, on described a plurality of bearing pins 4, respectively connect and get rid of piece 5, a described end and the bearing pin 4 that gets rid of piece 5 is hinged, the described the other end that gets rid of piece 5 is fixedlyed connected by a bolt 7 with a monolithic 6, described monolithic 6 and described casing 2 inwall sliding contacts.Directly contact with casing 2 inwalls by monolithic 6, produce friction, played good speed limit effect; When monolithic 6 is worn, can directly monolithic 6 be removed and change, easy for installation, also provide cost savings.
Claims (2)
1. centrifugal speed limiter, comprise case lid, casing, core wheel and the bearing pin more than 2 or 2, the center of circle, cross section of described bearing pin is circular around the center of circle, cross section of core wheel, it is characterized in that: on described a plurality of bearing pins, respectively connect and get rid of piece, a described end and the bearing pin that gets rid of piece is hinged, the described the other end that gets rid of piece is fixedlyed connected with a monolithic, described monolithic and described cabinet wall sliding contact.
