Background technique
As high-speed rail vibration noise is more and more prominent for the production and living of subjective reflection and the negative effect of instrument and equipment
And the requirement of high-speed railway and Line for Passenger Transportation to comfort is continuously improved, vibration and noise reducing is increasingly becoming the research of railway R&D institution
Main way.In this case, a popular research topic is become for the detection of track panel vibration.Currently,
Track plates vibration detection test in, sensor device is often directly installed on track plates, and by easy water proof material into
The processing of row water proof and dust proof.It is however noted that these simple materials are all often plastic products, set up in railway line
Under field environment, it is easy to because exposing to the weather causes to rupture, so that forfeiture acts on.The protection to sensor had both been lost in this way to make
With, and personnel is needed regularly to be replaced, the quality of detection test is not only influenced, but also bring very big bear to later maintenance
Load.Therefore, in order to meet the needs of currently for sensor arranging apparatus, it is necessary to design a kind of in fragment-free track slab
The fixation device of placement sensor.
Summary of the invention
The present invention provides a kind of sensor fastening devices for fragment-free track slab vibration measurement, solve existing measurement
The problems such as sensor fixation in device is too simple, is unfavorable for later maintenance.
The present invention can be achieved through the following technical solutions:
A kind of sensor fastening device for fragment-free track slab vibration measurement, including the shell for placing sensor,
The side of the shell is provided with cable hole, and bottom surface is connect with fragment-free track slab, and the top surface of the shell is set as being open, thereon
It is provided with sealing plate, is cooperated together by track, the cable hole and end cap cooperate, and the connecting line of the sensor passes through
Cable hole, end cap are connect with other devices.
Further, two opposite sides of the opening are provided with inside bending, and baffle, institute is arranged in another side
Sealing plate is stated using L-shaped structure, the L-shaped long side two sides are provided with the sliding slot with bending cooperation, the baffle and L-shaped short side
It is cooperated together by bolt, nut.
Further, the end cap is made of rubber material, and cross open is provided on cap, logical for connecting line
It crosses.
Further, the shell is made of metal material, and bottom surface is provided with through-hole, passes through chemical anchor bolts and non-fragment orbit
Plate connection, the sensor are fixed on the bottom surface of shell by magnet.
Further, the surface of the shell and sealing plate is coated with reflectorised paint.
The present invention is beneficial to be had the technical effect that
Placing sensor using Stainless Steel Shell can releasably connect the opening of shell and sealing plate by track structure
It is connected together, while being additionally provided with cable hole and corresponding rubber end cap, it, can be easily real using the elastic characteristic of rubber
Housings close is showed, has prevented rainwater under natural conditions, the factors such as wind-force damage sensor, guarantee the work peace of sensor
Entirely, the field service life for improving sensor, can not also interfere the connection of sensor Yu other devices.Due to opening and sealing plate
Track connection, alleviate workload and equipment cost for later period maintenance, and improve work efficiency, while device whole body sprays
Reflectorised paint has significant suggesting effect, and under conditions of preventing because being mounted on track plates side, night work or personnel walk about and cause
Scratch destruction.

Specific embodiment
With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.
As shown in Figure 1, the present invention provides a kind of sensor fastening devices for fragment-free track slab vibration measurement, mainly
For the fixed installation of acceleration transducer, vibrating sensor etc. and fragment-free track slab, including the shell for placing sensor
1, the side of the shell 1 is provided with cable hole 2, and bottom surface is connect with fragment-free track slab 3, and the top surface of the shell 1 is set as being open,
On be provided with sealing plate 4, cooperated together by track, the cable hole 2 and end cap 5 cooperate, and the connecting line of the sensor 6 is worn
Cross cable hole 2, end cap 5 is connect with other devices.
The whole shell 1 is in rectangular parallelepiped structure, and two sides for being open opposite are provided with inside bending 7, another
Baffle 8 is arranged in a side, which uses L-shaped structure, and L-shaped 41 two sides of long side are provided with the sliding slot cooperated with bending 7
42, through-hole is provided on the baffle 8 and L-shaped short side 43, the two is cooperated together by bolt 9 and nut 10, with
It avoids leading to the loosening between bending 7 and sliding slot 42 because of Long-term Vibration, shell 1 is caused to be intake into dirt.
The end cap is adopted 5 and is made of rubber material, and cross open 51 is provided on cap, is passed through for connecting line, due to
Rubber material has elasticity, and connecting line can restore automatically after passing through, and guarantees the leakproofness of shell 1.
As shown in Figures 2 and 3, which is made of metal material, and bottom surface is provided with through-hole, passes through chemical anchor bolts and nothing
Tiny fragments of stone, coal, etc. track plates 3 connect, which is fixed on the bottom surface of shell 1 by magnet, naturally it is also possible to by other means
It is fixed, so as to directly and accurately detect the Vibration Condition of fragment-free track slab, it is also possible to prevent to lead to sensor due to vibration
Damage etc. caused by movement.
The surface of the shell 1 and sealing plate 4 is coated with reflectorised paint, especially effectively identifies itself under night lights effect, has
Effect is prevented because being mounted on track plates side, is formed to scratch to it when on-line operation or personnel walk about and even be destroyed.
The present invention places sensor using Stainless Steel Shell and can tear the opening of shell and sealing plate open by track structure
It links together with unloading, while being additionally provided with cable hole and corresponding rubber end cap, it, can be very square using the elastic characteristic of rubber
Just housings close is realized, rainwater under natural conditions is prevented, the factors such as wind-force damage sensor, guarantee sensor
Work safety improves the field service life of sensor, can not also interfere the connection of sensor Yu other devices.Due to opening
It is connect with the track of sealing plate, alleviates workload and equipment cost for later period maintenance, and improve work efficiency, while device is complete
Body sprays reflectorised paint, has significant suggesting effect, under conditions of preventing because being mounted on track plates side, night work or personnel are walked
Destruction is scratched caused by dynamic.In addition, the present invention also has use cost low, facilitate popularization and application, there is conspicuousness application value
The advantages that.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that these
It is merely illustrative of, without departing from the principle and essence of the present invention, a variety of changes can be made to these embodiments
It more or modifies, therefore, protection scope of the present invention is defined by the appended claims.
