Definitions

  • the present specification refers to a device for detecting in advance the height of locking latches in installations for gage change, the purpose of which is to carry out the function of detecting that the height of the locking latches of rolling assemblies is within admissible limits, since otherwise the resulting collision could occur between the lower bridge of these latches and the unlocking guides when the rolling gear has entered the fixed installation or interchanger in order to change the gage, i.e., the pacing of the gage used by RENFE in their tracks to the universal gage known as UIC or vice versa.
  • This invention will find application in the industry devoted to railways and their auxiliary installations.
  • the locking latch bridge height in relation to a fixed height, such as the rail head, is variable, depending on the wear condition of the wheels, it is necessary to rely on a detecting device eliminating, in any way, the influence of the wheel diameter variation, i. e., from 880 mm for a new wheel to 830 mm for a wheel at the end of its useful lifetime.
  • the suitable device for attaining the pretended purpose must obviate the drawback of invading the low parts gauges for the width and height of freight cars, for which reason it must essentially have a protecting system or means allowing the device to be hidden in case that a locomotive passes on the zone where it is installed.
  • the device for detecting in advance the height of locking - latches in installations for gage change as proposed by the invention constitutes per se an evident solution to the present problems on this subject, since it performs, in an efficient manner, the function of detecting the height of the locking latches of the rolling assemblies and checking if the height itself of these locking latches is within admissible limits, obviating the resulting collision between the lower bridge of these latches and the unlocking guides.
  • the contemplated device is constitutes from the use, as main component of the assembly, of a frame, which is composed of four supports the function of which is to keep, at a fixed height, about 25 mm, height detectors for the locking latches, which avoid a rolling gear to enter the fixed installation having some latch out of its correct position.
  • Said frame is joined by means of said supports to a holding plate the function of which is to keep resilient stops fixed to it, disposing of second supports for polyamide wheels, the task of which is to take as reference the lower part of the railway vehicle bogie and to keep microswitches at the adequate distance.
  • the function of the resilient stops is to cushion the blow - with the bogie and absorb small inclinations which the bogie could have due to the difference of diameters between both wheels, adifference that, as already mentioned, is always owing to wear.
  • a set of four brushes is installed on the supports to clean the locking latches, so eliminating the possibility of the existence of foreign matters on them, such as papers, plastics, cans, and so on, and which are adhered to same.
  • the whole frame is guided by bars (14), slides on bushes and is suspended from springs, which are weather protected by a bellows-shaped protecting system, which allows the frame to rise and descend, depending, of course, on the height marked by the polyamide wheel.
  • This pneumatic cylinder is joined to the main support by means of locking elements.
  • the main support is screwed to four of the posts in the observation pit, and is destined to hold up the whole device.
  • the device for detecting locking latches is located in the observation pit at a distance from the concrete wall of about 2.80 meter, and it is fastened to four posts.
  • the observation pits are located at the entrance and exit of the fixed installation about 30 meter from it.
  • This 30 meter distance is considered as sufficient for, if the semaphoric signaling turns on because it has been detected the existence or presence of a latch fallen in the vehicle rolling element, having time enough to stop the train before this enters the fixed installation.
  • Figure 1 is a plan view of a fixed installation or interchanger on which the device for detecting in advance the height of the locking latches, which is the object of the invention, is incorporated.
  • Figure 2 is a plan view of the observation pit.
  • Figure 3 is a front elevational view of the device for detecting in advance the height of locking latches in installations for changing the gage.
  • Figure 4 is a side elevational view of the object illustrated in Fig. 3.
  • Figure 5 is, lastly, a side elevational view of the object illustrated in Figs. 3 and 4, located within the observation pit.
  • the device for detecting in advance the height of locking latches in installations for changing the gage is constituted by the following elements:
  • Fig. 1 it can be seen the existence of braked shaft detectors (5, 5'), and the observation pits (6, 6'), as well as the zones referenced as (7, 7'), which correspond to the lengths of the sections where the track brakes are mounted which will vary according to the slope where they will be installed, the railway track itself being referred as (8).
  • Figure 3 shows how the device for detecting in advance the - height of locking latches is constituted starting from a frame (9), which is formed by four supports (12) holding, at a certain height, about 25 mm, height detectors for the locking latches, the function of said detectors being to avoid a rolling gear to enter the fixed installation (4) with some latch out of its correct position.
  • the detectors (2) would enable a semaphoric signaling, so immediately stopping the train.
  • the frame (9) is joined, by means of supports (13), to a holding plate (11) having resilient stops (20), and fixed to these there are supports (19) for polyamide wheels (21), the function of which is to take as a reference the lower part of the vehicle bogie, keeping the microswitches (24) at the appropiate distance.
  • the function of the resilient stops (20) is to cushion, as far as possible, blows with the bogie, absorbing small inclinations which could carry the bogie due to the difference of diameters existing between both wheels owing to wear.
  • ramps In order to diminish the impact probably caused by the bogie against the polyamide wheels, ramps have been provided (28), which are joined to the holding plate (11) by means of supports, so smoothing the bogie entering the device for detecting the height of locking latches.
  • the whole frame (9) is guided by means of bars (14) , slides on bushes (15, 25), and is suspended from springs (22), which are weather protected by bellows or protecting system (23), being destined to allow the frame (9) to rise or descend, depending on the height marked by the polyamide wheel (21).
  • a hiding mechanism which is formed by a - pneumatic cylinder (26) which allows to hide 160 mm, which is a distance considered as sufficient not to interfere with the locomotive gauge.
  • This pneumatic cylinder (26) is joined to a support (16) by means of locking elements.
  • the cylinder configured hiding mechanism obviates the drawback of invading low parts gauges, and is capable of hiding the device of the invention in the case that a locomotive passes on the zone where it is installed.
  • the support (16), which is joined to the pneumatic cylinder (26), is welded to the first four posts of the observation pit (6, 6'), and it supports the whole device for detecting in advance the height of locking latches.
  • the device for detecting in advance the height of locking latches will be always located in the observation pit (6, 6') at a distance from the concrete wall of 2.80 m, fastened to eight posts.
  • the observations pits (6, 6') must be always located at the entrance and exit of the fixed installation (4), and about 30 m from it.
  • the device for detecting the height of locking latches in installations for changing the gage is constituted by a main frame (9), with a main support (10) and a holding plate (11), disposing of a microswitch support (12), as well as frame support (13), a guided bar (14) and a bush (15).
  • the invention provides a cylinder support (16), a column holder plug or block (17) and a guide profile (18), counting on a wheel support (19), a resilient stop (20), the corresponding polyamide wheels (21) and a spring (22) fitted with its adequate protector or bellows (23).
  • the device has a microswitch (24), a ball bearing or bushing (25) and counter rails (27).
