Abstract
The utility model discloses a lifting height limiter. One section of extension shaft is arranged at the rear end of a worm shaft of the lifting height limiter toward the outer part of a shell, a rotary encoder is installed at the rear end of the extension shaft via a coupling, and a data line connected with an external signal processing device is led out on the rotary encoder. The extension shaft and the worm shaft can be connected or welded through connecting holes or a connecting thread bushing. A protective cover covering the rotary encoder is installed on a coupling shell. In the utility model, the encoder and the lifting height limiter are connected into a whole, not only is the structure greatly simplified, but also the cost is reduced, and the lifting height limiter also has the functions of convenience for installation and use and double insurance.
Description
Technical field:
The utility model relates to lifting and conveying machinery, particularly a kind of adjustable height killer of installing and using on lifting and the conveying machinery of being applicable to.
Background technology:
The adjustable height killer that uses at present lifting and the conveying machinery all is single Stroke Control, if this control is malfunctioning, easily causes potential safety hazard.In order to improve the safe operation reliability of equipment, general position and the kinematic velocity that comes the monitoring moving facility by installing in addition rotary encoder additional.Existing rotary encoder all is mounted in circle cylinder one side of machinery, or is installed at other position with the height limiter homonymy, and this structure has not only increased productive costs and installation difficulty, and has increased again the work capacity of electrical equipment wiring.
Summary of the invention:
The purpose of this utility model provide a kind of can Effective Raise safety performance, simple in structure, adjustable height killer that cost is low, easy for installation.
The technical solution of the utility model is finished as follows, it comprises an adjustable height killer, it is characterized in that: outside housing, be provided with one section extension shaft in the worm shaft rear end of adjustable height killer, through coupler a rotary encoder is installed in the extension shaft rear end, leads to the data line that links to each other with the outward sign processing equipment at rotary encoder.Can be connected or weld by connecting bore or connecting thread cover between extension shaft and the worm shaft.The protective cover that rotary encoder is covered is installed at the coupler housing.
The utility model links into an integrated entity coder and adjustable height killer, not only greatly simplifies the structure, and has reduced cost, has again function easy to install, double insurance.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
The utility model is improvements over the prior art, it is to be provided with one section extension shaft 2 in worm shaft 1 rear end of an adjustable height killer 7 outside housing, with coupler 3 rotary encoder 4 is installed at the extension shaft other end, on the coupler housing, to the rotary encoder periphery protective cover 5 is installed, on coder, outwards leads to the data line 6 that links to each other with the outward sign processing equipment.Its principle of work is, the hoist roller axle rotates by the worm shaft driven rotary coder of adjustable height killer, one side is by the stroke of adjustable height killer controlled motion object, pulse count because of every rotation one circle of rotary encoder is certain on the other hand, the girth of reel is certain, just know like this speed of sports equipment by the rotating speed of coder, sports equipment end position and speed have been set, send deceleration or halt instruction by the data processing equipment contrast, play the effect of deceleration or Limited height and stroke.Realization is to the purpose of equipment duplicate protection.
