Abstract
The present utility model discloses a security supporting device for a lifting machine for ensuring that the lifting operations are safe, preventing rolling stocks from upsetting and providing a forewarning function. The security supporting device comprises a turn-screw (1) performing rotatory movements and a force-bearing nut (2) on the turn-screw, critically, the turn-screw (1) is also provided with a safety nut (3), and there is a small interval (c) between the force-bearing nut (2) and the safety nut (3). The security supporting device of the utility model has a simple structure and a professional design, the safety nut and the force-bearing nut can moves up and down synchronously because of intandem setting of the nuts, only if the force-bearing nut is broken, the safety nut begins to bear the weight of a rolling stock for preventing upsetting, alarm signals can be generated automatically by an inductor and an induction plate being closer when the set interval between the two nuts becomes smaller, therefore, the lifting operations can be ensured safe.
Description
Technical field:
The utility model relates to rolling stock's docking facility, particularly is a kind of safety supporting device of car lifting J-Horner.
Technical background:
When rolling stock enters shop maintenance, need by car lifting J-Horner it to be held up, so that rolling stock is overhauled, so the load nut of car lifting J-Horner bears the axial force of car body weight, the pressure of the helical surface of load nut is very big, make the wearing and tearing aggravation of load nut, strength reduction, easier generation damages, in case undue wear appears in the load nut, the accident generation that rolling stock topples can occur, the influence safety in production increases the cost of overhaul.
Summary of the invention:
Goal of the invention of the present utility model provides a kind of unwheeling job safety of guaranteeing, prevents the car lifting J-Horner safety supporting device that rolling stock topples and has warning function.
Realize that technical solution of the present utility model is as follows: comprise the turn-screw that rotatablely moves and the load nut on the turn-screw, key is also to be provided with a safety nut on turn-screw, and a little interval is arranged between load nut and the safety nut.
Described safety nut is provided with a proximity transducer, is provided with sensing chip at load nut correspondence position.
The distance at described interval is 3～6mm, is preferably 4mm.
The utility model is simple in structure, reasonable in design, tandem setting by safety nut and load nut, make two nut synchronization liftings, in normal unwheeling operation process, safety nut does not bear axial force, just when the load nut damages, safety nut is just undertaken car body weight and is prevented that car body from toppling, and sends alerting signal automatically during by setting pitch smaller between above-mentioned two nuts of proximity transducer and sensing chip, guarantees the unwheeling job safety.
Description of drawings:
Fig. 1 is an integral structure scheme drawing of the present utility model.
The specific embodiment:
See also Fig. 1, specific embodiment of the utility model is as follows: comprise the turn-screw 1 that rotatablely moves and the load nut 2 on the turn-screw 1, key is also to be provided with a safety nut 3 on turn-screw 1, and a little interval C is arranged between load nut 2 and the safety nut 3; Turn-screw 1, load nut 2 and safety nut 3 all adopt Acme thread, Acme thread possesses good self-locking property, can stop and locking load nut 2 and safety nut 3 tandem settings at an arbitrary position, when turn-screw 1 rotatablely moves, load nut 2 and safety nut 3 synchronization liftings; For preventing malicious event to take place because of 2 abrasion of load nut, the personal distance C that keeps setting between load nut 2 and the safety nut in normal working, the spacing of C is 3～6mm at interval, be preferably 4mm, when the pitch smaller of the personal distance C that sets, show that then load nut 2 has worn and torn or destroys, if 2 damages of load nut, then safety nut 3 is undertaken car body weight, prevents that car body from toppling; For precisely monitoring load nut 2 working conditions, on safety nut 3, be provided with a proximity transducer 4, be provided with sensing chip 5 at load nut 2 correspondence positions, proximity transducer 4 and sensing chip 5 are prior art, can adopt resistive transducer, capacitance-type sensor, inductive pickoff, piezoelectric transducer, magnetoelectric sensor, optical sensor or sonac, proximity transducer 4 and sensing chip 5 are fixed on load nut 2 and the safety nut 3 by support respectively, this both interval C is 4mm, when interval C＜3mm, proximity transducer 4 sends alerting signal.
Claims (3)
1. the safety supporting device of rolling stock's car lifting J-Horner, comprise the turn-screw (1) that rotatablely moves and the load nut (2) on the turn-screw (1), it is characterized in that on turn-screw (1), also being provided with a safety nut (3), a little interval (C) is arranged between load nut (2) and the safety nut (3).
2. by the safety supporting device of the described rolling stock of claim 1 car lifting J-Horner, it is characterized in that described safety nut (3) is provided with a proximity transducer (4), be provided with sensing chip (5) at load nut (2) correspondence position.
3. by the safety supporting device of the described rolling stock of claim 2 car lifting J-Horner, the distance that it is characterized in that described interval (C) is 3～6mm.
