Abstract
The utility model discloses a caging device used for the steel-wire rope type electric block, comprising an input axis and a case cap. The input axis is arranged on the case body; the case cap is connected with the case body and provided with the limit switch. The input axis is connected with the reduction gear inside the case body; the reduction gear is connected with a memory cam which is used with the limit switch. As the above mentioned structure is adopted, this cam type caging device can be provided with such merits as accurate spacing and low totalized errors.
Description
Technical field
The utility model discloses a kind of Steel-wire Rope Type Electric Block Caging Device, belong to the elevator machinery technical field.
Background technology
Inhibiting device is a kind of requisite safety guard of electric block; at present; the electric block inhibiting device of producing all is rod-pulling types, and its keystone configuration comprises the pull bar that the reel limit is provided with, and the two ends of pull bar respectively are provided with a positive stop; positive stop and limit switch are used; during work, thereby the up-and-down movement of steel rope causes the rope guide sway on the reel, when rope guide is run into positive stop; touch inhibiting device, thereby reach spacing purpose.The inhibiting device of this structure, its pull bar and cable drum must be isometric, the cucurbit lifting altitude is high more, and pull bar is just long more, and the volume of its cucurbit is just big more, increased manufacturing cost, and pull bar is long more, and easy more quilt hits curved, unstability, cause the malfunctioning of inhibiting device, staff's life security can not get ensureing.
The utility model content
For addressing the above problem, the utility model purpose is to provide a kind of simple in structure, Steel-wire Rope Type Electric Block Caging Device that volume is little, safe and reliable.
The technical scheme that its technical matters that will solve the utility model adopts is: a kind of Steel-wire Rope Type Electric Block Caging Device, comprise the input shaft that places on the casing, with the case lid that is provided with limit switch in the casing bonded assembly, it is characterized in that: the described input shaft speed reduction gearing interior with placing casing is connected, speed reduction gearing is connected with the memory cam, and memory cam and limit switch are used.
Of the present utility modelly further be set to: also be connected with universal coupling between input shaft and the speed reduction gearing, the installation of being convenient to limit switch is regulated.
Of the present utility modelly further be set to: the memory cam is provided with a set screw, can realize the adjusting on a large scale of its lifting altitude.
Of the present utility modelly further be set to: described speed reduction gearing comprises intermeshing worm gear, worm screw, worm gear is connected with driving gear set by adapter shaft, driving gear set is connected with another driving gear set by adapter shaft, and another driving gear set is connected with the memory cam by transmission shaft.
Of the present utility modelly further be set to: described driving gear set comprises intermeshing two transmission gears.
After the utility model adopts said structure, its speed reduction gearing is realized bigger speed ratio by the transmission of worm gear, worm screw and transmission gear, pass to the memory cam at last, the inhibiting device of this cam-type has spacing accurately stable, repeats the little advantage of cumulative errors.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
