Description
Technical field
The utility model relates to building hoist, prevents that especially cage from going out the safety device at guide rail bracket top.
Background technology
Along with high speed development of national economy, the improving constantly of state-of-art domesticly developed increasing building hoist enterprise, and the safety problem of building hoist has also become a task that long-term endeavour is perfect of engineering machinery field.Current society is that people-oriented, in this industry based on manual operation of building hoist, more should pay attention to personal safety.If because of some error of the operating personal of building hoist, elevator is travelled exceed the safe altitude of floor and skid off track, personnel's injures and deaths take place, so just run counter to the principle of safety in production.Therefore, in order to prevent the generation of this type of accident, need a kind of safe device of design to prevent that building hoist from going out the floor safe altitude, guarantee that carrying personnel's personal safety is a task of carrying out for a long time.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of building hoist cage erosion control ejection device, prevents that building hoist from going out the floor safe altitude, ensures carrying personnel's personal safety.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of building hoist cage erosion control ejection device, comprise guide rail bracket, the cage of building by standard knot, described cage is by transmission dolly and guide rail bracket sliding block joint, described transmission dolly is provided with motor, gear, described guide rail bracket is provided with tooth bar, described gear and the engagement of described tooth bar; Described transmission dolly is provided with the erosion control ejection device, described erosion control ejection device comprises travel switch, and described travel switch is connected with described motor, and induction shell fragment one end of described travel switch is provided with wheel trolley, described wheel trolley and described induction shell fragment articulate, described wheel trolley and described tooth bar rolling touch.The transmission dolly is provided with roller, and this roller cooperates with guide rail bracket, and the transmission dolly can be slided on guide rail bracket.Transmission dolly band cage and is moved up and down on guide rail bracket together, in the height of transmission carriage walking in safety, the wheel trolley of the travel switch on the transmission dolly contacts with tooth bar on the guide rail bracket all the time, and have certain squeese pressure between wheel trolley and the tooth bar, make the induction shell fragment of travel switch be in non-triggering state; The maximum height of tooth bar is the safe altitude of setting, when transmission dolly when upwards walking exceeds the safe altitude of setting, wheel trolley breaks away from tooth bar, the induction shell fragment action triggers travel switch of travel switch produces signal, the signal of travel switch is passed to motor, the instruction motor shuts down, thereby makes cage can not go out safe height, ensures carrying personnel's personal safety.
As improvement, described erosion control ejection device also comprises adapter plate, and described adapter plate is fixed on the described transmission dolly, and described travel switch is installed on the described adapter plate.
As improvement, described adapter plate is arranged on the top of transmission dolly.
The beneficial effect that the utility model is compared with prior art brought is:
The setting of erosion control ejection device can prevent that building hoist from going out the floor safe altitude, ensures carrying personnel's personal safety; The induction that utilizes mechanical travel switch cooperation contact is as the erosion control ejection device, and is simple in structure, reliable operation.
