Technical Field
[0001] The utility model relates to the technical field of railway construction, in particular to a transmission integrated turnout switch machine locking iron tight contact force sensor. Background Art
[0002] During the railway construction, turnout machines are installed. There will be a gap between the locking iron and the locking frame, which needs to be filled with a gasket. In the prior art, a sensor is placed in this gap to measure the force value in real time, which can also serve as a gasket to prevent the switch machine from malfunctioning after the locking force sensor is installed. However, the middle part of the two sides of the M-shaped metal plate of the existing sensor adopts a concave structure, which is a shear beam strain structure. The sensing force area is located on both sides of the convex pressure-bearing surface. There are only two sensing areas, and the force measurement is unbalanced, thereby affecting the accuracy of the force measurement. Utility Model Content

The specific technical solution is as follows:
[0004] A transmitter-integrated turnout switch machine locking iron-tight force sensor comprises an M-shaped metal plate and a transmitter circuit box, wherein the transmitter circuit box is welded on a transmitter circuit base, and the transmitter circuit base and the M-shaped metal plate are integrally formed.

[0005] The other side of the M-shaped metal plate is provided with multiple pressure points, which are distributed at the center of the back side of the force sensing area and are higher than the plane of the M-shaped metal plate, ensuring that each force sensing area is subjected to maximum deformation and increasing the sensitivity of the sensor signal.
[0006] Furthermore, a transmission circuit is provided inside the transmission circuit box, and the direction of the wires output from the transmission circuit box is parallel to the M-shaped metal plate surface, which facilitates the routing of the wires and saves installation space.

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Example 1: See Figure 1-3 The illustrated embodiment shows a transmitter-integrated turnout switch machine locking iron-tight force sensor, comprising an M-shaped metal plate 1 and a transmitter circuit box 2. The transmitter circuit box 2 is welded on a transmitter circuit base 9. The transmitter circuit base 9 and the M-shaped metal plate 1 are integrally formed. One side of the M-shaped metal plate 1 is a plane, and a plurality of force sensing areas 8 are provided. The signal lines of the force sensing areas 8 are arranged in a wiring groove 7. A hole is opened at the end of the wiring groove 7 behind the transmitter circuit base 9. The signal line is introduced into the transmitter circuit box 2 through the hole. The signal line is sealed by glue in the wiring groove 7.
[0016] like Figure 2As shown, the other side of the M-shaped metal plate 1 is provided with a plurality of pressure points 6, which are distributed at the back center of the force sensing area 8 and are higher than the plane of the M-shaped metal plate 1, ensuring that each force sensing area 8 is subjected to maximum deformation and increasing the sensitivity of the sensor signal.
[0017] like Figure 1 or Figure 3 As shown, a transmitting circuit 5 is provided inside the transmitting circuit box 2. The direction of the wire 3 output from the transmitting circuit box 2 is parallel to the surface of the M-shaped metal plate 1, which is convenient for routing the wire 3 and saves installation space. The output wire 3 passes through the pagoda-shaped tightening nut 4. The pagoda-shaped structure facilitates the installation of a wire protection tube outside the wire 3, facilitates on-site wiring, and meets the requirements of the harsh environment of the rail site.
[0018] The utility model is installed between the locking iron and the locking frame. The surface where the convex pressure point 6 area of the sensor is located is in close contact with the locking iron, and the locking frame is firmly fixed on the basic rail. When the track changes, the switch machine action rod moves and drives the lock hook at one end to move together. The inclined surface on the lock hook moves to fit with the inclined surface of the locking iron to form a close-fitting inclined surface. At the same time, there is an adjustment inclined surface under the action rod. The two inclined surfaces form a wedge-shaped structure, so that a huge extrusion force is generated between the inclined surfaces of the lock hook and the locking iron. The lock hook and the locking iron are locked together, and the other end of the action rod pushes the track to be changed to the specified position and fixes it. At this time, the locking extrusion force on the locking iron will be transmitted to the convex pressure point 6 area of the close-fitting force sensor. The sensor can detect the locking force value in real time to determine whether the force value meets the track change requirements.
[0019] One side of the M-shaped metal plate 1 of the utility model is a plane, and a plurality of force measuring sensing areas 8 are provided to ensure balanced force and improve force measuring accuracy. The other side of the M-shaped metal plate 1 is provided with a plurality of pressure points 6, which are distributed at the back center position of the force measuring sensing area 8 and are higher than the plane of the M-shaped metal plate 1, to ensure that each force measuring area is subjected to the maximum deformation and to increase the sensitivity of the sensor signal.

The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which shall fall within the scope of the utility model to be protected.
