Abstract
A caging device for crane height comprises a lifting winding barrel shaft, an outer shaft sleeve, an inner shaft sleeve, a shaft end transparent cover, an altimeter and a shaft end pressing cover. A front end of the inner shaft sleeve is embedded at a shaft end of the lifting winding barrel shaft. The altimeter penetrates through the inner shaft sleeve, and is fixedly connected with the shaft end of the lifting winding barrel shaft. The outer shaft sleeve penetrates through the shaft end transparent cover, and is sleeved onto a projecting outer ring of the inner shaft sleeve. The shaft end pressing cover is fixedly connected with the shaft end transparent cover, and fixes the outer shaft sleeve to the shaft end of the lifting winding barrel shaft. The caging device for crane height has the advantages of compact structure, wide adjusting scope, accurate data, convenient installation, and low manufacture cost.
Description
Technical field
This utility model relates to a kind of inhibiting device, and particularly a kind of safe and reliable hoisting crane height limiting device belongs to hoisting crane manufacturing technology field.
Background technology
At present, most of hoisting crane height limiting devices are installed on the hoisting drum axle head, adopt the sprocket-type type of drive; This mode is easy for installation, is easy to maintenance, but for the reel of multiple wraps; Can't the accurate response rope capacity, error is bigger, and because during the arm luffing; Luffing is bigger to the suspension hook position effects, so global error is bigger, therefore can produce potential safety hazard.
Summary of the invention
Goal of the invention: the purpose of the utility model provides and a kind ofly both maintained easily, again can accurate response suspension hook lifting altitude position, realize the hoisting crane height limiting device of height defencive function.
Technical scheme: a kind of hoisting crane height limiting device; Comprise that hoisting drum axle, outer shaft, internal axle sleeve, axle head pass through lid, altitude instrument and axle head gland; The front end of said internal axle sleeve is embedded in the axle head of hoisting drum axle; Said altitude instrument passes internal axle sleeve captives joint with the axle head of hoisting drum axle, and said outer shaft passes axle head and passes through lid and be placed on the outstanding outer ring of internal axle sleeve, and axle head gland and axle head cover thoroughly captives joint the axle head that outer shaft is fixed in the hoisting drum axle.Said outer shaft is used for the adjusting play, and internal axle sleeve is used to connect altitude instrument and rises drum shaft.On-the-spot require to adjust the number of turns of altitude instrument according to lifting altitude, altitude instrument speed ratio type selecting is carried out according to the hoisting crane parameter request.
Beneficial effect: the utility model compact conformation, setting range is wide accurate, easy for installation with data, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
As shown in the figure; A kind of hoisting crane height limiting device; Comprise that hoisting drum axle 1, outer shaft 2, internal axle sleeve 3, axle head cover 4 thoroughly, altitude instrument 5 and axle head gland 6, the front end of said internal axle sleeve 3 is embedded in the axle head of hoisting drum axle 1, said altitude instrument 5 passes internal axle sleeve 3 captives joint with the axle head of hoisting drum axle 1; Said outer shaft 2 passes axle head and covers 4 thoroughly and be placed on the outstanding outer ring of internal axle sleeve 3, and axle head gland 6 and axle head cover 4 thoroughly captives joint the axle head that outer shaft 2 is fixed in hoisting drum axle 1.Said outer shaft 2 is used for the adjusting play, and internal axle sleeve 3 is used to connect altitude instrument 5 and rises drum shaft 1.On-the-spot require to adjust the number of turns of altitude instrument 5 according to lifting altitude, altitude instrument 5 speed ratio type selectings are carried out according to the hoisting crane parameter request.
