Abstract
The utility model relates to a permanent-magnet spring sensor for rail vehicle velocity-measuring and safety alarm. An existing device for vehicle velocity measuring and location measuring has the defects of complicated structure, large weight, large size, oversize connecting fittings, and inconvenient installation and debugging. The utility model comprises a casing 1 the interior of which is fixedly provided with a rare earth permanent magnet block 2, wherein, the casing 1 is fixed with installed rails of a measured section through a clamping board 3 and fastening fittings 4 which can adopt screw bolts, etc., the bottom surface of the side surfaces of the permanent magnet block 2 are provided with magnetic shield boards 5, and the short circuit can be avoided. The utility model is used for data acquisition, and protection, alarm, and automatic control of road junctions of marshalling stations such as locomotive velocity measurement, location measurement, etc.
Description
The utility model relates to a kind of rail conducting magnetic circuit that utilizes and carries out sensing, tests the speed and the permanent magnetic spring formula sensor of security alarm for rolling stock.
Existing railway locomotive tests the speed, the positioning apparatus complex structure, and weight is big, volume is big, and attaching parts is excessive, and the Installation and Debugging inconvenience.
The purpose of this utility model is to provide a kind of rolling stock security alarm permanent magnetic spring formula sensor that tests the speed, can simplified structure, reduce volume and weight, and cost-cutting, the on-site installation debugging is convenient.
The purpose of this utility model is achieved in that
The rolling stock security alarm permanent magnetic spring formula sensor that tests the speed, its composition comprises: housing, described housing internal fixation is equipped with the rare earth permanent magnet piece, and described housing fixes by clamp and fastener and rail, and magnetic shield plate is equipped with in the bottom surface and the side of described permanent magnets.
The above-mentioned rolling stock security alarm permanent magnetic spring formula sensor that tests the speed is equipped with magnetic control spare between described permanent magnets bottom surface and the described magnetic shield plate.
The above-mentioned rolling stock security alarm permanent magnetic spring formula sensor that tests the speed, described permanent magnets is the 1-8 piece.
Advantage of the present utility model is:
1. simple in structure, in light weight.The side magnetic shield plate directly is fixed on the magnetic shield plate of permanent magnets bottom surface.Simple in structure, under the prerequisite that guarantees same work effect, can make original M20 * 180 tie bolts into M16 * 100 bolts, weight lowers greatly.
2. adopt the rare earth permanent magnet piece as magnetic source, sensing is effective, can be made of monoblock, also can use the polylith distributed arrangement.
3. the on-site installation debugging is easy.This product can be adjusted the magnetic field center height by the number of adjusting magnetic control spare in the erecting stage, adjusts the distance between this product and the wheel, to adjust the magnetic-field intensity at wheel place, the induction of control magnetic signal.
4. along with the development of IT technology, this product can show huge market potential in the management of railway.This product generally is paired setting, at rolling stock by when sections of sensors is set, the magnetic circuit conducting, contactless collection and output signal, when vehicle leaves sections of sensors, magnetic circuit disconnects, form a switching value thus, the signal that collects is not had the computation center that is pooled to of rectification, just can draw the locomotive operation position, separated by a distance for example 1000 meters this product is set, just can measure data such as the speed of a motor vehicle, meter axle, this product does not need power supply, safeguards easily, is difficult for being damaged.
Accompanying drawing 1 is the later-model structural representation of this folder.
Accompanying drawing 2 is birds-eye vieies of accompanying drawing 1.Accompanying drawing 3 is connection structure scheme drawings of permanent-magnet pieces and magnetic control spare.
Accompanying drawing 4 is birds-eye vieies of accompanying drawing 3.
Be further described below in conjunction with accompanying drawing:
Embodiment 1:
The rolling stock security alarm permanent magnetic spring formula sensor that tests the speed, its composition comprises: housing 1, described housing 1 internal fixation is equipped with rare earth permanent magnet piece 2, described housing 1 fixes by the rail of clamp 3 and fastener 4 with the determined highway section of being installed, fastener 4 can adopt the bolt of M18 * 100 etc., magnetic shield plate 5 is equipped with in the bottom surface of described permanent magnets 2 and side, can avoid short circuit.
Embodiment 2:
The embodiment 1 described rolling stock security alarm permanent magnetic spring formula sensor that tests the speed is equipped with magnetic control spare 6 between the bottom surface of described permanent magnets 2 and the described magnetic shield plate 5.By adjusting the quantity of these magnetic control spares, can adjust the height of permanent magnets easily, to guarantee that distance between this product and the rail at 38-40mm, can obtain preferable effect through checking like this.
Embodiment 3:
Embodiment 1 or the 2 described rolling stocks security alarm permanent magnetic spring formula sensor that tests the speed, described permanent magnets is the 1-8 piece.Can make monoblock, also can make even distribution types such as 4,8, can permanent magnets 2 be clipped between the described magnetic control spare 6 with bolt 7 and fix.
