[0002] A proximity switch is a position switch that does not require mechanical direct contact operation with moving parts. When an object approaches the sensing surface of the proximity switch to the operating distance, the switch can be actuated, thereby driving a DC electrical appliance or providing a control command to a computer device.

[0003] As a signal feedback component, proximity switches have been widely used in various industries. In its conventional installation method, a single proximity switch can only be adjusted longitudinally.

[0004] There are many proximity switches equipped on the detection equipment in the railway transportation industry for triggering trains and collecting data. When the detection object is a whole train carbody or multiple - formation wheel sets, it is required that multiple proximity switches for triggering the detection equipment be arranged horizontally at equal intervals. However, due to various factors such as uneven sleeper spacing and on - site environment, it will cause the proximity switches to be unable to meet the equal - interval installation, resulting in difficult debugging of the detection equipment and inaccurate data collection.

[0030] The following further describes the present utility model in detail with reference to the drawings and embodiments.

[0031] Referring to Figures 1 to 3 as shown, the device for adjusting the position of the proximity switch in this embodiment includes a proximity switch mounting plate 2, an angle support member 3, a sensor track clamping block 4, a terminal track clamping block 5, and an aluminum profile 6.

[0032] Among them, the proximity switch 1 is installed on the proximity switch mounting plate 2. The proximity switch mounting plate 2 is provided with oblong holes perpendicular to the direction of the rail, and the position of the proximity switch 1 can be longitudinally adjusted. Preferably, the proximity switch 1 is connected to the proximity switch mounting plate 2 by bolts.

[0033] Among them, the proximity switch mounting plate 2 is installed on the aluminum profile 6, and the lateral distance is adjustable. Preferably, the proximity switch mounting plate is locked to the aluminum profile 6 by bolts.

[0034] Specifically, the aluminum profile 6 has a T-shaped groove on all four sides, and the proximity switch mounting plate 2 is locked to the aluminum profile 6 with T-bolts and nuts, and the position of the proximity switch mounting plate 2 can be adjusted laterally at will on the aluminum profile 6.

[0035] Among them, there are two or more proximity switches 2 on a single aluminum profile 6, and they can be arranged at equal intervals according to the usage scenario. That is, multiple proximity switches 2 (proximity switch mounting plates 2) are arranged at equal intervals on the aluminum profile 6.

[0036] Moreover, there is one or more aluminum profiles 6, and multiple aluminum profiles 6 can be spliced together.

[0037] Among them, the aluminum profile 6 is fixed on the sensor track clamp 4 with an angle support 3 and is cooperated with the terminal track clamp 5 to be locked on the rail.

[0038] The aluminum profile 6 is connected and fixed to the angle support 3. The angle support 3 is connected to the sensor track clamp 4 in a vertically movable manner.

[0039] Specifically, the angle support 3 is composed of multiple plates (preferably integrally formed). There are screw holes on the vertically erected plate above, a horizontally placed plate in the middle, and a plate perpendicular to the ground below. There are waist-shaped holes on the plate perpendicular to the ground below for height adjustment (as Figure 4 shown).

[0040] One side of the aluminum profile 6 is connected and fixed to the vertically erected plate of the angle support 3 with a T-bolt.

[0041] The plate perpendicular to the ground below the angle support 3 is connected to the sensor track clamp 4 with bolts: the waist-shaped holes of the plate perpendicular to the ground below are locked on the sensor track clamp 4 with bolts, so that the angle support 3 can be adjusted in height on the sensor track clamp 4, thereby driving the proximity switch 1 above the angle support 3 to be adjusted in height.

[0042] In addition, the angle support 3 is used to avoid the magnetic field lines of the proximity switch from the rail or other metal parts to prevent false triggering.

[0043] When the above methods of horizontal adjustment, vertical adjustment or height adjustment cannot meet the position adjustment of the proximity switch 1 (such as the influence of weld scars on the rail at the installation position), the angle support 3 can be directly replaced according to the on-site installation situation.

[0044] The angle of the angle support 3 (this angle refers to the included angle between the vertically erected plate above and the horizontally placed plate in the middle) can range from 0 to 15°, such as 5° and 8°.

[0045] The sensor track clamp 4 has its own screw. One side is stuck on the bottom surface of the rail. Its own screw is under the rail and passes through the terminal track clamp 5 opposite to the rail and is locked and fixed with a nut on the rail.

[0046] In summary, the above proximity switch 1 is fixed on the aluminum profile 6 through the proximity switch mounting plate 2, and the aluminum profile 6 is fixed on the angle support 3. The angle support 3 is connected to the sensor rail clamp 4 and finally locked on the rail with the terminal rail clamp 5.

[0047] In this embodiment, each single aluminum profile 6 is respectively equipped with 2 sensor rail clamps 4 and terminal rail clamps 5, which can ensure the stability and reliability of each single aluminum profile 6.

[0048] The device for adjusting the position of the proximity switch in this embodiment makes use of the aluminum profile 6 as a standard part, which has the advantages of adjustable length and convenient splicing. As the reference base plate of the proximity switch 1, the proximity switch 1 is indirectly installed on the T-shaped groove. Its adjustable characteristics solve the contradiction that the rail sleeper spacing is uneven in the railway while the detection equipment requires the proximity switch 1 to be equally spaced, reduce the difficulty of equipment installation and debugging, improve the compatibility of the layout of the proximity switch 1, and can be applicable to the triggering requirements of various detection equipment.

[0049] In addition, the device for adjusting the position of the proximity switch in this embodiment can also be adjusted in multiple aspects such as horizontally (along the rail direction), vertically (perpendicular to the rail direction), height, and angle.

[0050] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention; the technologies not involved in the present invention can be realized through the prior art.
