Abstract
The utility model relates to hoisting equipment, in particular to a steel wire rope loosening prevention apparatus for a hoisting device, which comprises a limit sleeve, a shaft rod and a spring. A central through hole arranged on the lower portion of the limit sleeve is used for the shaft rod to penetrate through, a spring abutting end is formed on the upper portion of the shaft rod, and the spring is sleeved on the shaft rod and abutted between the spring abutting end and the central through hole; a limit baffle block is arranged at the uppermost end of the shaft rod; the lower portion of the shaft rod penetrates through the central through hole, and a joint connected with a steel wire rope is arranged on the lower portion of the shaft rod; and the shaft rod is connected in parallel with a stroke switch. Compared with the prior art, when the hoisting device is broken down because a climbing bucket is clamped on a track and unable to move or a limit switch at a lower limit position is damaged to lead the climbing bucket to continue moving downwards, the steel wire rope loosening prevention apparatus can timely trigger the stroke switch to shut down the device and give out alarm, avoids lifting the spring of the device, and leads the lifting device to work more safely and reliably.
Description
Technical field
The utility model relates to lifting means, is meant a kind of steel wire rope locking device that is used for lifting means especially.
Background technology
Climbing in the process that orbits that struggles against of lifting means when motor reverses (being the reel counter-rotating), being climbed bucket and descending.Two kinds of faults often take place in the decline process: 1, climbing struggles against to be stuck on the track does not move; 2, the limit switch of lower position broken cause climbing bucket continue descending, up to track till the below is blocked by mechanical position limitation; These two kinds of faults can cause steel wire rope not have pulling force attached on the reel and unclamp cruelly or steel wire rope oppositely is wrapped on the reel, thereby make whole lifting means paralysis.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, and a kind of steel wire rope locking device that is used for lifting means is provided, and can in time find fault, stopping alarm.
The utility model adopts following technical scheme:
A kind of steel wire rope locking device that is used for lifting means, comprise a stop bit cover, an axostylus axostyle and a spring, the bottom of this stop bit cover is provided with central through hole and passes through for this axostylus axostyle, the top of this axostylus axostyle is formed with the spring abutment end, and this spring housing is located on this axostylus axostyle and is resisted against between this spring abutment end and this central through hole; The top of this axostylus axostyle is provided with the stop bit block; The bottom of this axostylus axostyle is passed this central through hole and is provided with the joint that links to each other with steel wire rope in this bottom; This axostylus axostyle is connected to the one stroke switch.
According to a better embodiment of the present utility model, described stop bit cover and described travel switch all are fixed on the support.
According to a better embodiment of the present utility model, the bottom of described axostylus axostyle is connected with a connector, and this bottom links to each other with described joint by this connector, and is provided with a back-up ring between this bottom and this connector, and this back-up ring links to each other with described travel switch.
According to a better embodiment of the present utility model, the top of described axostylus axostyle is arranged with a cover.
According to a better embodiment of the present utility model, described joint is the steel wire rope wedge joint.
According to a better embodiment of the present utility model, described lifting means is the bucket type concrete batch plant.
A kind of steel wire rope locking device that is used for lifting means of the present utility model in use, when lifting means in normal operating condition following time, by the steel wire rope and the deadweight of climbing bucket spring is compressed, make the upper end of the stop bit block retaining of axostylus axostyle upper end at the stop bit cover; Be stuck in and not move on the track or the limit switch of lower position has been broken when causing climbing the descending situation of bucket continuation when bucket appears climbing in lifting means; spring will overcome the steel wire rope deadweight by its restoring force and rise; thereby move on the drive axostylus axostyle, thereby trigger travel switch, stopping alarm.
By above-mentioned to description of the present utility model as can be known; compared with prior art; a kind of steel wire rope locking device that is used for lifting means of the present utility model is owing to can bucket occur climbing at lifting means and be stuck in and not move on the track or the limit switch of lower position has been broken and caused climbing bucket timely triggering travel switch when continuing descending fault; stopping alarm; avoid the situation of lifting means spring to take place, made lifting means work safer, reliable.
