Description
Technical field
The utility model relates to a kind of elevator safety gear, particularly a kind of gradual elevator safety tong.
Background technology
In elevator device, progressive safety gear is a requisite safety device.It is normally fixing on the elevator car, when elevator operation exception, and set out velocity limiter action time, shift mechanism can pull the voussoir on progressive safety gear, makes it clamp cage guide, with elevator brake car.
But mainly contain the progressive safety gear of two types at present, a kind of is symmetrical expression, it needs the symmetrical branch of two voussoirs, and action simultaneously, the subject matter that this structure exists is that complex structure, volume are larger, install loaded down with trivial details, cost is higher, and application force cannot accomplish complete equilibrium; Another kind is non-symmetrical, and it only has side to have voussoir, and opposite side is exactly directly friction lining, and when braking, have the side obvious effect power of voussoir large, this will cause when braking, and car entirety lateral excursion can occur, and generation is rocked more greatly.
Utility model content
The purpose of this utility model is, provides a kind of gradual elevator safety tong of self-balancing.It can when elevator brake car the gripping power of self-equalizing both sides, therefore can make the stable braking of lift car, and the utility model simple for structure, assemble convenient, compact is convenient to install.
The technical solution of the utility model: a kind of gradual elevator safety tong of self-balancing, be characterized in: the horizontal housing comprising semi-surrounding structure, the U-shaped inside casing that laterally can slide in horizontal housing is provided with in horizontal housing, the inner side of wherein one end of U-shaped inside casing is provided with friction lining, the other end is provided with the set screw through U-shaped inside casing, and the nut portion of set screw is positioned at outside U-shaped inside casing; The inner side of described U-shaped inside casing is provided with push pedal; The side of push pedal props up set screw, opposite side is connected with Compress Spring, the Compress Spring other end is connected with pressing plate, voussoir is provided with between friction lining on pressing plate and U-shaped inside casing, described pressing plate is dip plane near the one side of voussoir, described voussoir is dip plane near the one side of pressing plate, and the another side of voussoir is provided with friction lining; Dip plane on described pressing plate and the dip plane on voussoir are close to mutually, and the upper end of the dip plane of pressing plate is provided with roller, and the dip plane of voussoir is provided with groove corresponding with roller shape together, and the groove depth of described groove reduces from top to bottom successively.
In the gradual elevator safety tong of above-mentioned self-balancing, upper and lower two end faces of described horizontal housing are equipped with breach; Horizontal housing upper surface is provided with the first track adjusting wheel and the second track adjusting wheel, and the second track adjusting wheel is positioned at the indentation, there of horizontal housing upper surface; Be provided with extension spring in described horizontal housing, the upper and lower two ends of described extension spring are all connected with steel rope, walk around the first track adjusting wheel and the second track adjusting wheel successively, be finally connected with voussoir top after wherein connecting the horizontal housing of steel wire penetrating of upper end; Be connected with pull bar after the horizontal housing of the steel wire penetrating of described connection extension spring lower end, and the steel rope being positioned at pull bar front end is also arranged with limiting stopper.Extension spring can cushion the pulling force of pull bar, and extension spring is arranged on horizontal housing inside, integral structure can be made more compact, not easily sandwich foreign matter.
In the gradual elevator safety tong of aforesaid self-balancing, described U-shaped inside casing is rigid metal material.
Compared with prior art, the utility model by arranging the U-shaped inside casing that can be free to slide in the horizontal housing of semi-surrounding structure, pressing plate and the voussoir of one-sided distribution are set at U-shaped inside casing, when voussoir does not upwards lift, U-shaped inside casing can clamping guide-rail, and can be free to slide due to U-shaped inside casing, therefore can automatically offset when its gripping power in both sides is not identical, until both sides gripping power is identical, can prevents car from occurring the phenomenon laterally just offset, achieve the function of a self-balancing.And utilization of the present utility model regulates the Compress Spring of predetermincd tension to coordinate roller on pressing plate and voussoir and groove by set screw, the utility model can be made can to realize the level and smooth gradual braking process of multistage: in voussoir uphill process, the power that the gripping power that guide rail is first subject to produces primarily of the relative movement of two dip plane provides, and when voussoir rises to a certain degree, roller enters groove, two dip plane are progressively separated, relativity become roller and groove, make the impact receiving again gash depth of gripping power.So the rear journey that voussoir is rising, the raising Rate smoothing of gripping power rises, and makes braking procedure of the present utility model more level and smooth, and can meet enough large braking force in limited actuating length.In addition, interior frame structure of the present utility model is very convenient when assembling, and it is fixing to be convenient to installation, regulates, therefore can reduce the requirement to setting accuracy because the actual brake component in housing can be free to slide.
