Abstract
The utility model relates to a limiting device, in particular to a rotating and limiting device for a coke dry quenching elevator, which comprises a transmission shaft, a rotating wheel and a limiting block, wherein, the transmission shaft is connected with a transmission shaft of a wire rope reel of the elevator directly. The device solves the problem that safety production of elevators is influenced due to poor sensitivity of rotating and limiting, ensures normal operation of the elevator and facilitates a dry quenching furnace to operate steadily.
Description
Technical field
The utility model relates to a kind of inhibiting device, a kind of specifically coke dry quenching hoister rotary limit device.
Background technology
Coke dry quenching hoister is a kind of large-scale lifting kind equipment, and the groundwork of this equipment is to be promoted to 50 meters high dried putting out on the stove with weighing 55 tons burnt jar from electric locomotive, red Jiao in burnt jar is put into the dried stove that puts out carry out dried putting out.Because gig master's position limitation protection upper limit when promoting has only a upper limit and weight, lower limit has only a position limitation protection, and auxiliary protection adopts German SCHMERSAL rotary stopper.The main effect of this rotary stopper is that auxiliary protection puts into operation immediately in case main position limitation protection goes wrong, to guarantee gig and personal security.Because the sensitivity of SCHMERSAL rotary stopper is too poor, cause gig can't guarantee in lifting or decline process safe, major cause is that the external diameter of its revolving wheel has only 10mm, its girth is 31.4mm only, and the complete hoisting depth of gig is up to 50 meters, be that gig promotes or descends 1 meter, and the revolving wheel of rotary stopper only rotates 0.62mm, the distance of the spacing closing of contact of rotation of 0.62mm is all not enough.If gig arrives the lower position when descending, and the amazing effect of the spacing evil idea of lower limit this moment, gig will continue to descend, and the result is that steel rope will be disconnected by strand, burnt fallers ground.And the upper limit is badly spacing if arrive the upper limit in lifting process, and it is more fearful that gig will continue to promote that consequence, and direct consequence is burnt jar and will falls from 50 meters high high-altitudes.So as the rotary stopper of auxiliary protection is exactly place in operation immediately under main spacing badly unexpected situation, to guarantee the safe and reliable operation of this special equipment of gig.
Summary of the invention
Technical problem to be solved in the utility model is: at the too poor shortcoming of above existing coke dry quenching hoister rotary limit device sensitivity, propose a kind of highly sensitively, can guarantee the coke dry quenching hoister rotary limit device that gig moves fully.
The technical scheme that the utility model solves above technical matters is: the coke dry quenching hoister rotary limit device, comprise transmission shaft, revolving wheel and limiting stopper, and transmission shaft directly links to each other with the transmission shaft of gig cable drum.
Limiting stopper is that Japanese Omron is spacing.Revolving wheel is that external diameter is the copper disk of 150mm.
The utility model has the advantages that: the transmission shaft of rotary limit device directly links to each other with the transmission shaft of power drum, adopts the mechanical type transmission, has improved sensitivity.The inner spacing stability that improves work in highly sensitive Japanese Omron that adopts, revolving wheel adopt copper external diameter be the disk of 150mm increasing its girth, the benefit that increases girth is that the external diameter when disk moves the height that a bit just should reflect the lifting or the decline of gig in real time.The utility model has solved rotary stopper influences mine hoist safety production problem because of sensitivity is too poor, guaranteed normally carrying out of gig, helps the whole dried smooth operation that puts out stove.

The specific embodiment
Embodiment one
The structure of present embodiment as shown in Figure 2, Fig. 1 is the coke dry quenching hoister structural representation.Coke dry quenching hoister comprises power drum 1, reel transmission shaft 2 and steel rope 3, and steel rope 3 is used to lift by crane burnt jar 4.The coke dry quenching hoister rotary limit device contains transmission shaft 5, revolving wheel 6 and limiting stopper 7, transmission shaft 6 directly links to each other with the reel transmission shaft 2 of gig cable drum 1, inner limiting stopper 7 adopts highly sensitive Japanese Omron spacing, and it is the disk of 150mm that revolving wheel 6 adopts copper external diameter.The transmission shaft 5 of rotary limit device directly links to each other with reel transmission shaft 2, adopts the mechanical type transmission, has improved sensitivity.The inner spacing stability that improves work in highly sensitive Japanese Omron that adopts, revolving wheel 6 adopt copper external diameter be the disk of 150mm increasing its girth, the benefit that increases girth is that the external diameter when disk moves the height that a bit just should reflect the lifting or the decline of gig in real time.
The utility model can also have other embodiment, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
Claims (2)
1. the coke dry quenching hoister rotary limit device comprises transmission shaft, revolving wheel and limiting stopper, it is characterized in that: described transmission shaft directly links to each other with the transmission shaft of gig cable drum.
