Abstract
The invention discloses a steel-wire rope type electric block stroke type lifting limiting device. The steel-wire rope type electric block stroke type lifting limiting device is characterized by comprising an upper limiting microswitch and a lower limiting microswitch, wherein the upper limiting microswitch and the lower limiting microswitch are arranged at the two ends inside a winding drum shell and respectively comprise a microswitch body, a roller and a trigger button arranged on each microswitch body, each roller is connected with each microswitch body through a pressing rod, and when a rope guider moves to the position where the upper limiting microswitch or the lower limiting microswitch is located, each roller presses downwards to drive each pressing rod to trigger each trigger button. The steel-wire rope type electric block stroke type lifting limiting device has the advantages that service life of the lifting limiting device is prolonged, steel consumption is reduced, the weight of a crane is reduced, and the upper limiting position and the lower limiting position of a steel-wire rope type electric block are controlled accurately.
Description
Technical field
The present invention relates to a kind of inhibiting device that hoists, especially a kind of steel-wire rope type electric block stroke type inhibiting device that hoists.
Background technology
Conventional crane hoisting spacing employing turbine and worm formula or weight hammer type, the turbine and worm formula all is in running state in the whole decline process that hoists, and large to the wearing and tearing of turbine and worm pair, the life-span is short; And weight hammer type utilizes lever principle, be pure mechanical part, outside the required steel of hoisting crane itself, separately need to increase steel, complex structure.
Summary of the invention
The present invention seeks to: provide a kind of simple in structure, quality is light, and consumptive material is few and the life-span is long, and the steel-wire rope type electric block stroke type that can control accurately the upper limit position of steel-wire rope type electric block and the lower position inhibiting device that hoists.
technical scheme of the present invention is: a kind of steel-wire rope type electric block stroke type inhibiting device that hoists, it is characterized in that, comprise upper limit micro-switch and the lower limit micro-switch of being located at respectively reel enclosure two ends, described upper limit micro-switch and described lower limit micro-switch include the micro-switch body, roller and be positioned at the trigger button on described micro-switch body, described roller is connected by depression bar with described micro-switch body, when rope guide moves to described upper limit micro-switch or described lower limit micro-switch position, described roller presses down and drives the described trigger button of depression bar triggering.
Preferably, described upper limit micro-switch and described lower limit micro-switch also comprise open contact and normally closed contact, when described roller presses down the described trigger button of drive depression bar triggering, and the closed signal that hoists accordingly that also sends of described open contact.
Preferably, the number of described upper limit micro-switch is 2, and when rope guide moved to first upper limit micro-switch position, reel ran slowly; When rope guide continued to move to second upper limit micro-switch position, reel was out of service.
Preferably, when rope guide moved to described lower limit micro-switch position, reel was out of service.
More preferably, also comprise the connecting rod of being located at the reel enclosure, described connecting rod two ends are respectively equipped be used to placing the long gain of described upper limit micro-switch and described lower limit micro-switch.
Concrete operation step of the present invention is as follows, when weight hoists motion, the reel counter-rotating, rope guide, to left movement, when rope guide moves to upper limit position, at first triggers first upper limit micro-switch, reel runs slowly, rope guide continues second upper limit micro-switch of motion triggers, and reel is out of service, and namely weight stops the operation of rising; When weight descends operation, the reel forward, rope guide moves right, and when rope guide moves to lower position, triggers the lower limit micro-switch, and reel is out of service, and namely weight stops the operation that descends.
Advantage of the present invention is: not only extend the present invention and hoist the inhibiting device life-span, reduce steel consumption, alleviate hoisting crane weight, and realize accurate upper limit position and the lower position of controlling steel-wire rope type electric block.
The accompanying drawing explanation
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is position limited inching switch structural representation of the present invention;
Fig. 2 is structural representation of the present invention;
Wherein: 1 upper limit micro-switch, 2 lower limit micro-switchs, 3 micro-switch bodies, 4 rollers, 5 trigger buttons, 6 depression bars, 7 open contacts, 8 normally closed contacts, 9 connecting rods, 10 long gains, 11 rope guides.
The specific embodiment
embodiment: shown in 2, a kind of steel-wire rope type electric block stroke type inhibiting device that hoists, comprise 2 upper limit micro-switchs 1 and 1 lower limit micro-switch 2, also comprise the connecting rod 9 of being located at the reel enclosure, connecting rod 9 two ends are respectively equipped be used to placing the long gain 10 of upper limit micro-switch 1 and lower limit micro-switch 2, upper limit micro-switch 1 and lower limit micro-switch 2 include micro-switch body 3, roller 4, be positioned at the trigger button 5 on micro-switch body 3, open contact 7 and normally closed contact 8, roller 4 is connected by depression bar 6 with micro-switch body 3, when rope guide 11 moves to upper limit micro-switch 1 or lower limit micro-switch 2 position, roller 4 presses down and drives depression bar 6 triggering trigger buttons 5, open contact 7 closures are also sent the signal that hoists accordingly, namely when rope guide 11 moves to first upper limit micro-switch 1 position, reel runs slowly, when rope guide 11 continues to move to second upper limit micro-switch 1 position, reel is out of service, when rope guide 11 moved to lower limit micro-switch 2 position, reel was out of service.
Concrete operation step of the present invention is as follows, when weight hoists motion, the reel counter-rotating, rope guide 11, to left movement, when rope guide 11 moves to upper limit position, at first triggers first upper limit micro-switch 1, reel runs slowly, rope guide 11 continues second upper limit micro-switch 1 of motion triggers, and reel is out of service, and namely weight stops the operation of rising; When weight descends operation, the reel forward, rope guide 11 moves right, and when rope guide 11 moves to lower position, triggers lower limit micro-switch 2, and reel is out of service, and namely weight stops the operation that descends.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All modifications that the Spirit Essence of main technical schemes is done according to the present invention, within all should being encompassed in protection scope of the present invention.
