Description

Rail detection unit special fixture

Technical field

The present invention relates to a kind of installation special fixtures of rail wireless sensor network detection unit, are particularly suitable for high-speed iron The detection unit of road gapless rail monitoring measurement wireless network Sensor Network.

Background technique

China has become high-speed railway operating mileage longest in the world at present, overall trip speed highest, and building scale is maximum Country, maintenance and monitoring to high-speed railway become highly important project.Rail is safe structure most basic in high-speed railway Part, the constraint due to gapless track long rail string by rail joint resistance, fastener resistance and ballast resistance, when rail temperature changes When, axially temperature stress will be generated in long rail string.When rail temperature declines, longitudinal temperature tensile stress is larger in rail, in rail The weakness such as weld seam, crackle cause life and property because rail fracture may occur for unbearable biggish longitudinal temperature pulling force Loss.Therefore, particularly significant to internal rail stress condition monitoring.

With the continuous development of Internet technology, wireless sense network using increasingly extensive.Pacify in the rail of high-speed railway In full monitoring, the rail of location at risk is selected, wireless sense network measuring unit is installed on it, constitutes rail state measurement network It is a kind of effective solution scheme.Wireless sense network measuring unit is that one kind based on wireless communication technique exploitation is pacified for rail The data collection system monitored entirely.It is responsible for the analog signal that sensor measurement is arrived, and sends out after data amplification, filtering, conversion Gateway is given, gateway passes through network again and sends data to database server.Wireless sense network measuring unit exists as one kind Line real-time monitoring system, the implementation of this technology need to guarantee that measuring unit is safely and reliably mounted on tested rail, thus. For high-speed railway and the measurement request of other rail traffics, need to prepare dedicated fixture, solid and reliablely measuring unit It is mounted on the web of the rail side of rail.

Existing a set of four fixture blocks of fixture are more troublesome during installation, and when installation needs to hammer urgent, fixture block pretightning force And mated condition is difficult unanimously, when operating cost.Since Railway Site environment is very severe, when winter temperature is lower, fixture is by electricity Chemical rotten candle etc. is dismantled relatively difficult after a period of use than more serious, and especially claw is difficult to dismantle after getting rusty.

Summary of the invention

To solve the above-mentioned problems, the present invention provides rail detection unit special fixtures.

Technical solution of the present invention:

A kind of rail detection unit special fixture is designed for the cylindrical shell of detection unit, mainly by front baffle 4, preceding Fastening plates 5, afterframe 14, rear fastening plates 13, limited block 12, handwheel 6, claw 3, fastening bolt 9 and fastening nut 7 form；

Both described front baffle 4 and afterframe 14 are arranged symmetrically in the two sides of rail 1, are respectively equipped with thereon and rail 1 The locating notch being bonded completely, the locating notch are engaged with 1 rail bottom of rail；Front baffle 4 and afterframe 14 are worn respectively by both ends The fastening bolt 9 crossed on the middle part square of preceding fastening plates 5 and rear fastening plates 13 is fixed as one；Fastening bolt 9 passes through preceding tight The fastening nut 7 of 5 side of solid plate and nut split pin 8 lock, and three controls the spacing among front baffle 4 and afterframe 14 Meanwhile stable clamping force is provided for front baffle 4 and afterframe 14；

The front baffle 4 is mainly made of long slab, support plate and middle part square section, and long slab plays the role of leaf spring, long The space for installing limited block 12 and the projecting plate with small sircle hole are symmetrically arranged on plate, handwheel 6 is symmetrically mounted on front baffle 4 lower surface；It is equipped with the side of protrusion at left and right sides of front baffle 4, realizes the installation positioning of detection unit 2；In the square section of middle part Circular hole for being cooperated with fastening bolt 9；

The afterframe 14 is mainly made of long slab, support plate and middle part square section；

2 shape of detection unit is in the form of a column, and is bonded completely at the web of the rail application of a surface of rail 1, with front frame 4 joint place of frame is bonded completely, utilizes 4 or so side located lateral of front baffle, and compress it fixation by claw 3；It is described 3 upper section of claw be hook solid, for compressing detection unit 2, lower section is chamfered edge screw rod, is cooperated with the threaded hole of handwheel 6；

12 top of limited block is equipped with waist-shaped hole, move up and down it can only with the cooperation of claw 3, is not able to rotate；Limit Position 12 two sides of block have slot and front baffle 4 to cooperate, and lower part has the circular groove of U-lag and handwheel 6 to cooperate, and prevent about 6 play of handwheel, Handwheel 6 is rotated, claw 3 moves downward, and the top crotch of claw 3 compresses detection unit 2；

The outer rim of the handwheel 6 has the tooth socket of similar gear, exposes under 4 both sides lower part projecting plate of front baffle, front frame Small sircle hole on 4 lower part projecting plate of frame is inserted into small sircle hole, hand when claw 3 compresses detection unit 2 with handwheel split pin 10 It takes turns split pin 10 and passes through bending after 6 tooth socket of handwheel, to limit the rotation of handwheel 6, prevent detection unit 2 from loosening；

The long slab of the preceding fastening plates 5 and rear fastening plates 13 is made of spring steel.

The invention can provide stable clamping force under the premise of keeping previous generation fixture function, reduce and rail reality The notch depth of border occlusion, and volume is reduced, thus it is easy for assemble or unload, it is easy to carry, it effectively raises fixture and uses effect Rate.
