Description

Technical Field

[0001] This utility model relates to the field of sensor technology, and in particular to a switching resistance sensor for a turnout gap monitoring system. Background Technology

[0002] Currently, turnout switch machines are key equipment in railway systems for controlling track switching. Their switching resistance and the axial force of the actuating lever during train passage directly affect the working status of the turnout and the safety of train operation.

[0003] In existing technologies, the adjustable connector iron and the locking rod are usually connected by bolts and pins, and the force is indirectly detected by an external sensor, which has problems such as complicated installation and low measurement accuracy. Utility Model Content

[0004] In view of this, in order to solve the problems existing in the technical background, this utility model proposes a switching resistance sensor for a turnout gap monitoring system, the specific technical solution of which is as follows:

[0005] A switch gap monitoring system conversion resistance sensor includes a sensor body, one end of which is provided with an electronic compartment containing a transmitter circuit, and the other end of which is provided with a locking thread and a pin hole. A wiring hole is opened inside the sensor body, which connects the patch area and the electronic compartment. A force-sensitive element is provided on the patch area.

[0006] Furthermore, the sensor body is provided with a locking rod connection area and an adjustable connector iron connection area. When the sensor body is installed, it passes through the through hole connecting the adjustable connector iron and the locking rod to connect the two. When the switch machine pulls or pushes the adjustable connector iron, it drives the locking rod to move together. At this time, the sensor detects the pulling force and pressure of the switch machine pulling or pushing.

[0007] Furthermore, the locking rod connection area is located in the middle of the sensor body. The two sides of the locking rod connection area are deformation areas, and the outer diameter of the deformation area is smaller than that of the locking rod connection area. The two outer sides of the deformation area are adjustable connector iron connection areas, and the outer diameter of the adjustable connector iron connection area is larger than that of the deformation area. The outer diameter of the deformation area is smaller than that of the adjustable connector iron connection area and the outer diameter of the locking rod connection area, which increases the deformation amount of the deformation area under stress and improves the accuracy of detection.

[0008] The above technical solution has the following beneficial effects:

[0009] The sensor of this invention features a pin-shaped structure with a threaded end. It is installed between an adjustable connector and a locking rod, connecting the two and replacing the original bolt pin. This invention optimizes the deformation zone structure, amplifies the amount of deformation under stress, and achieves precise measurement by combining it with a sensitive element. The pin-shaped design directly replaces the original bolt pin, making installation convenient. Attached Figure Description

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Example 1: See Figure 1 , Figure 2 The switch gap monitoring system shown includes a conversion resistance sensor, comprising a sensor body, an electronic compartment 1 at one end of the sensor body, a transmitter circuit inside the electronic compartment 1, a locking thread 5 and a pin hole 6 at the other end of the sensor body, a wiring hole 2 inside the sensor body, the wiring hole 2 connecting the patch area 3 and the electronic compartment 1, and a force-sensitive element on the patch area 3.

[0015] The sensor body is provided with a locking rod connection area 7 and an adjustable connector iron connection area 8. When the sensor body is installed, it passes through the through hole connecting the adjustable connector iron and the locking rod to connect the two. When the switch machine pulls or pushes the adjustable connector iron, it drives the locking rod to move together. At this time, the sensor detects the pulling force and pressure of the switch machine pulling or pushing.

[0016] The locking rod connection area 7 is located in the middle of the sensor body. The two sides of the locking rod connection area 7 are deformation areas 9, and the outer diameter of the deformation area 9 is smaller than the outer diameter of the locking rod connection area 7. The two outer sides of the deformation area 9 are adjustable connector iron connection areas 8, and the outer diameter of the adjustable connector iron connection area 8 is larger than the outer diameter of the deformation area 9. The outer diameter of the deformation area 9 is smaller than the outer diameter of the adjustable connector iron connection area 8 and the outer diameter of the locking rod connection area 7, which will increase the deformation of the deformation area 9 under force and improve the accuracy of detection.

[0017] This invention is used to detect the switching resistance of a turnout switch machine during turnout switching and the axial force of the actuating rod when a train passes through the turnout. It monitors the operation of the turnout gap system of the switch machine in real time online to ensure the safe track changing and driving of trains.

[0018] This utility model features a shaft pin structure with a threaded end. It is installed between the adjustable connector iron and the locking rod, connecting the adjustable connector iron and the locking rod, replacing the original bolt pin. The locking thread 5 of this utility model is used to install the nut 4 to fix the sensor and prevent the sensor from rotating; the pin hole 6 prevents the locking nut from loosening and falling off.

[0019] The locking thread 5 of this invention has a nut 4 limiting step machined at its end to prevent excessive locking force of the nut 4 from causing irregular deformation of the deformation zone 9. The outer surface of the adjustable connector iron connection area 8 and the locking rod connection area 7 is machined with symmetrical connection gap areas to ensure the accuracy of the sensor's force measurement.

[0020] The sensor of this invention features a pin-shaped structure with a threaded end. It is installed between an adjustable connector and a locking rod, connecting the two and replacing the original bolt pin. This invention optimizes the deformation zone 9 structure, amplifying the amount of deformation under stress, and achieves precise measurement in conjunction with the sensitive element. The pin-shaped design directly replaces the original bolt pin, making installation convenient.

[0021] The basic principles and main features of this utility model have been described above. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this utility model.
