Abstract
The invention discloses a tip-over preventive device for a suspension type railcar. The tip-over preventive device comprises an oscillating frame, rotary shafts, reverse compressing roller trains, a rotary pin, a support, an adjusting draw bar, a rubber coated spring, a threaded sleeve and a locking nut, wherein the reverse compressing roller trains are reversely pressed on a rail, one end of the oscillating frame is connected with the reverse compressing roller trains by the rotary shafts, the reverse compressing roller trains can rotate on the rotary shafts, the other end of the oscillating frame is connected with the support by the rotary pin, the oscillating frame can rotate along the rotary pin, and the support is fixed onto a traveling trolley. Reverse compression force to the rail can be adjusted by the tip-over preventive device, the rotary pin is movably connected with the oscillating frame and the support, and extending and contracting of the rubber coated spring can be adjusted by turning the locking nut so as to adjust the reverse compression force of the roller trains. Accordingly, swinging of the railcar can be relieved by the reverse compression force provided by the roller trains when the railcar is under transverse load suddenly, the bonding strength of the railcar is increased, and the grade ability of the railcar is improved advantageously.
Description
Technical field
The present invention relates to a kind of anti-tilting apparatus for the suspension type rail car, relate in particular to and a kind ofly make that the suspension type rail car can be stablized, reliably operation, realization belongs to bridge security and detects the auxiliary device technical field the safety detection of bridge and the anti-tilting apparatus of maintenance.
Background technology
Rail vehicle is in operation process, in the situation that the prominent lateral load (carrying such as wind) of meeting, horizontal power will be so that rail vehicle rocks, and the existing weight of rail vehicle self that can only rely at present overcomes prominent lateral load of meeting, so larger the rocking of rail vehicle generation; If in the situation that infinite place, even the phenomenon of tumbling can occur, rail vehicle de-orbits and drops, and will cause huge injury.At present, similar anti-tilting apparatus on rail vehicle, also do not occur and avoid the safety problem that causes because of the lateral load effect.
Summary of the invention
The object of the invention is to: a kind of anti-tilting apparatus for the suspension type rail car is provided, the anti-tilting apparatus of reverse compression track is set by the walking dolly at the suspension type rail car, solve rail vehicle in operation process, the huge technical matters of rocking even tumbling that prominent chance produced in the time of horizontal year realizes that rail vehicle is stable, reliably operation; Thereby can solve above-mentioned problems of the prior art by actv..
The objective of the invention is to realize by following technical proposals: a kind of anti-tilting apparatus for the suspension type rail car, comprise reverse pinch rollers group on track of swing span, rotating shaft, back-pressure, ship and resell on another market, supporting base, adjusting yoke, encapsulate spring, jam nut and screw thread bush, one end of described swing span links to each other with reverse pinch rollers group by rotating shaft, described reverse pinch rollers group can be rotated in rotating shaft, the other end of swing span links to each other with supporting base by shipping and reselling on another market, swing span can be along shipping and reselling on another market rotation, and described supporting base is fixed on the walking dolly.
As a kind of optimal way, the middle part of screw thread bush and described swing span is fixed.
As further preferred, described adjusting yoke one end links to each other with screw thread bush, and the other end passes the encapsulate spring of compression and is connected by jam nut with adapter plate on the walking dolly.
As a kind of optimal way, described reverse pinch rollers group comprises four rolling, and four rolling is symmetrically set in the both sides of swing span.
Compared with prior art, beneficial effect of the present invention: the anti-tilting apparatus that is used for the suspension type rail car by the present invention is regulated the reverse thrust size that track is provided, owing to shipping and reselling on another market as being flexibly connected, regulate the elongation of encapsulate spring, the size that shortening realizes the reverse thrust of adjustment roll wheels by the rotation lock nut, can be when meeting lateral load, the reverse thrust that provides by roller set alleviates rocking of producing when rail vehicle is prominent meets lateral load, increase the adhesive ability of rail vehicle, be conducive to rail vehicle and promote hill climbing ability.
Description of drawings

Fig. 2 is the A-A cutaway view of Fig. 1;
Schematic diagram when Fig. 3 uses for this anti-tilting apparatus;
Another side schematic diagram when Fig. 4 uses for this anti-tilting apparatus.
Among the figure: the 1-swing span, the 2-rotating shaft, the reverse pinch rollers group of 3-, 4-ships and resell on another market, the 5-supporting base, 6-adjusting yoke, 7-encapsulate spring, 8-jam nut, the 9-screw thread bush, 11-track, 12-anti-tilting apparatus body, 13-walking dolly.
The specific embodiment
The present invention is further illustrated below in conjunction with specific embodiments and the drawings.
Disclosed all features in this specification sheets, or the step in disclosed all methods or the process, except the speciality and/or step of mutual repulsion, all can make up by any way, unless special narration all can be replaced by other equivalences or the alternative features with similar purpose, namely, unless special narration, an embodiment in a series of equivalences of each feature or the similar characteristics.
Shown in Fig. 1-2, the present invention is used for the anti-tilting apparatus of suspension type rail car, it comprises reverse pinch rollers group 3 on track of swing span 1, rotating shaft 2, back-pressure, ship and resell on another market 4, supporting base 5, adjusting yoke 6, encapsulate spring 7, jam nut 8 and screw thread bush 9, one end of described swing span 1 links to each other with reverse pinch rollers group 3 by rotating shaft 2, described reverse pinch rollers group 3 can be rotated in rotating shaft 2, the other end of swing span 14 links to each other with supporting base 5 by shipping and reselling on another market, swing span 1 can be along 4 rotations of shipping and reselling on another market, and described supporting base 5 is fixed on the walking dolly; Screw thread bush 9 is fixed with the middle part of described swing span 1, and described adjusting yoke 6 one ends link to each other with screw thread bush 9, and the other end passes the encapsulate spring 7 of compression and is connected by jam nut 8 with adapter plate on the walking dolly; Described reverse pinch rollers group 3 comprises four rolling, and four rolling is symmetrically set in the both sides of swing span 1.
As shown in Figure 3-4, use procedure of the present invention and realization principle are as follows:
During use, in advance the encapsulate spring is arranged to compressive state, encapsulate spring bottom is connected on the connecting panel or wallboard of walking dolly 13, then by jam nut this anti-tilting apparatus body 12 is fixed on the walking dolly 13, roller set is pressed on the lower flange of track 11 all the time, and the other end of anti-tilting apparatus body 12 is captiveed joint with walking dolly 13 by supporting base.Because ship and resell on another market as being flexibly connected, elongation, the shortening of regulating the encapsulate spring by the rotation lock nut come, thereby regulate the size that 12 pairs of tracks 11 of this anti-tilting apparatus body provide reverse thrust; Walking dolly 13 is in operation process, during prominent chance lateral load, this anti-tilting apparatus body 12 provides reverse thrust, increases walking dolly and interorbital adhesive ability, alleviate rocking when rail vehicle is prominent meets horizontal year, and this reverse thrust also helps the raising of rail vehicle hill climbing ability.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
