Abstract

The utility model discloses a bearing hinge for mine throttles. The bearing hinge comprises upper and lower door-leaf hinge pieces (6), upper and lower door-post hinge pieces (2) and connecting shafts (3), wherein the upper and lower connecting shafts are in the same axis; The bearing hinge is characterized in that each door-leaf hinge piece is an iron plate with a plurality of bolt holes (7), one end of the iron plate is fixedly connected with one end of a support arm (1), the other end of the support arm and the connecting shafts are welded into a whole, each door-post hinge piece corresponding to the door-leaf hinge pieces is an iron plate with a plurality of bolt holes, a bearing pedestal (4) is welded on a door-post iron plate, a bearing arranged in the bearing pedestal is in sleeve connection with the connecting shafts, two right-triangular steel pieces (5) are arranged below the bearing pedestal, and the two right-angled edges of each steel piece are respectively welded to the lower parts of the door-post iron plate and the bearing pedestal. The bearing hinge disclosed by the utility model is flexible in rotating, a door leaf does not incline to one side or deform, and the service life of the bearing hinge can be dozens of times larger than that of the traditional hinge.

Description

The Air Throttle in Mine Pit bearing hinge

Technical field

The utility model relates to a kind of mine air door member, especially a kind of Air Throttle in Mine Pit bearing hinge.

Background technology

As everyone knows, because the environment of mine is more abominable, moist, corrosive gas content is high, in order to improve the application life of Air Throttle in Mine Pit, reduce the timber use amount, save production cost, existing Air Throttle in Mine Pit generally all selects density higher, the material that resistance to corrosion is strong is made doorframe and door leaf, for further improving door leaf application life, usually set up metal reinforcing plates at door leaf, therefore door leaf weight is large, connect doorframe and breakdown often appears in door leaf because door leaf is overweight with traditional door leaf hinge, distortion, situations such as door leaf lateral deviation and reduce door leaf application life, for improving Air Throttle in Mine Pit application life and going slick property, develop a kind of rational in infrastructure, the Air Throttle in Mine Pit bearing hinge of science is very necessary.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and goes slick, long service life, the Air Throttle in Mine Pit bearing hinge that easy to assembly, fault is few.The purpose of this utility model realizes by following technical proposals: on the utility model comprises, lower two door leaf leaf of hinge, on, lower two door pillar leaf of hinge and connecting axle, two connecting axles are on same axial line up and down, it is characterized in that a door leaf leaf of hinge is the iron plate piece with several bolts hole, iron plate piece one end and support arm one end are affixed, the support arm other end and connecting axle are integrally welded, the door pillar leaf of hinge corresponding with door leaf hinge iron plate piece is the iron plate piece with several bolts hole, be welded with bearing support on the door pillar iron plate piece, be provided with the socket of bearing and connecting axle in the bearing support, the bearing support below is provided with two right-angled triangle steel discs, and two right-angle sides of steel disc weld with door pillar iron plate piece and bearing support below respectively.

Be individually fixed on the door leaf position corresponding with door pillar with door pillar hinge iron plate piece by bolt door leaf hinge iron plate piece during use and make up and down that two connecting axles are inserted in bearing support with connecting axle and get final product on same axial line.From above-mentioned situation as can be known, the purpose of this utility model can realize, compared with prior art, the utility model rotation flexibly, door leaf can lateral deviation not hang angle and distortion, can reach the decades of times of traditional hinge application life.
