Description

Technical Field

[0001] This utility model relates to a ZD6 type electric switch machine notch displacement sensor, and in particular to a ZD6 notch displacement sensor that is easy to install. Background Technology

[0002] The existing ZD6 electric switch machine notch displacement sensor structure consists of a mounting frame and a base. The upper part of the mounting frame acts as a top cover. The mounting frame and the sensor base are installed as one unit and then installed into the switch machine. Due to its large size, it cannot be directly inserted into the installation position. The contact seat needs to be removed during installation, which is difficult to operate and time-consuming and labor-intensive on-site modification. In addition, there is no place in the structure to add shims, so there is no height adjustment function.

[0003] The existing ZD6 electric switch machine notch displacement sensor structure has several obvious drawbacks:

[0004] 1. Integrated sensors are bulky and take up a lot of space.

[0005] 2. Installing the sensor requires first removing the contact socket, which is difficult, time-consuming and labor-intensive. It requires two people to work together to first disconnect the wiring, then disconnect the contact socket, then install the sensor, install the contact socket, and then restore the wiring, which takes more than an hour.

[0006] 3. The sensor height is not adjustable.

[0007] 4. After installation, it is impossible to observe and measure the gap between the bottom of the sensor and the top of the indicator rod. Summary of the Invention

[0008] The purpose of this invention is to provide a ZD6 notch displacement sensor that is easy to install, occupies little space, is easy to install, saves time and effort during installation, has an adjustable height, and is easy to observe after installation.

[0009] The purpose of this utility model is achieved by providing a ZD6 notch displacement sensor that is easy to install. It is characterized by comprising a mounting frame, a switch machine contact seat, a base, a top cover, a circuit board housing, a magnetic strip, an adjustment plate mounted on the bottom shell of the switch machine, modular pre-assembled components, and an indicator rod. The indicator rod is an assembly consisting of a main rod and a secondary rod. The mounting frame and the switch machine contact seat are bolted to the bottom shell of the switch machine. The base and the top cover are connected by screws to form a sensor assembly, which is then connected to the mounting frame using screws. An adjustment plate is located between the mounting frame and the top cover to adjust the height of the sensor.

[0010] A reading circuit board is installed in the circuit board housing. The circuit board housing has holes. Rivets are inserted into the holes on the base and the circuit board housing to connect them. Two circuit board housings are installed in the base. The adapter circuit board is connected to the top cover with screws. One end of the connecting wire is soldered to the adapter circuit board, and the other end is a plug.

[0011] The magnetic strip is pasted into a groove on the upper surface of the indicator rod, and then the groove is filled with epoxy glue. After the glue dries, the glue surface is sanded smooth so that the glue surface is flush with the upper surface of the indicator rod.

[0012] The gap between the bottom surface of the base and the top surface of the indicator rod is less than 1.5mm.

[0013] The aforementioned gap can be adjusted using a surface pad adjustment plate.

[0014] There is potting compound around the circuit board of the sensor assembly.

[0015] The advantages of this utility model are: it is beneficial for adding or modifying gap monitoring systems on existing switch machines, it is easy to install, saves time and effort, the original indicator rod can continue to be used after attaching magnetic strips, saving costs, the sensor height is easy to adjust, and the installation structure is reliable.

[0016] The advantages of this utility model are:

[0017] 1. To reduce the size of the sensor, the mounting bracket and the top cover are separated into two parts, and the mounting bracket is designed as a flat plate to reduce its size and fit into a small space.

[0018] 2. Optimize the sensor structure by separating the sensor assembly from the mounting bracket, making it easy to install and allowing it to be installed inside the switch machine without removing the contact base.

[0019] 3. The sensor height can be adjusted by pre-inserting a 0.5mm thick stainless steel pad, and then adding or removing the pad as needed based on the site conditions. The adjustment accuracy is 0.5mm.

[0020] 4. Due to the reduced size of the mounting plate, a gap is left after installation, allowing for observation and measurement of the gap between the bottom of the sensor and the top of the indicator rod using a feeler gauge.

[0021] 5. This utility model is easy to install, requiring no removal of wiring and contact points, and can be installed by a single person in just ten minutes.

[0026] To further illustrate the technical means and methods adopted by this utility model to achieve its intended purpose, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figure 1 and Figure 2 As shown, this utility model relates to a ZD6 notch displacement sensor that is easy to install. Its features include: a mounting frame 1, a switch machine contact seat 8, a base 3, a top cover 2, a circuit board housing 4, a surface pad adjustment plate 5, and modular pre-assembled components. The mounting frame 1 and the switch machine contact seat 8 are mounted on the bottom shell 9 of the switch machine using bolts 13. The base 3 and the top cover 2 are connected by screws to form a sensor assembly, which is then connected to the mounting frame 1 using screws. A surface pad adjustment plate 5 is located between the mounting frame 1 and the top cover 2 to adjust the height of the sensor.

[0028] A reading circuit board 11 is installed in the circuit board housing 4. The circuit board housing 4 has holes. Rivets are inserted into the holes on the base 3 and the circuit board housing 4 to connect them. Two circuit board housings 4 and an adapter circuit board 10 are installed in the base 3. The adapter circuit board 10 is connected to the top cover 2 with screws. One end of the connecting wire 12 is soldered to the adapter circuit board 10, and the other end is a plug.

[0029] The two adapter circuit boards 10 can read the magnetic strip data on the upper surface of the main rod and the auxiliary rod of the two indicator rods 6, respectively.

[0030] The magnetic strip 7 is pasted into the groove on the upper surface of the indicator rod 6, and then the groove is filled with epoxy glue. After the glue dries, the glue surface is sanded smooth so that the glue surface is flush with the upper surface of the indicator rod. The indicator rod 6 is a component composed of the main rod and the auxiliary rod, and is installed on the bottom shell 9 of the switch machine.

[0031] The installation method of this utility model is as follows: When installing on the original model, first install the mounting bracket 1, and then install the sensor assembly assembled from the top cover 2, base 3, circuit board shell 4, surface pad adjustment plate 5, adapter circuit board 10, reading circuit board 11, and connecting wire 12 on the mounting bracket 1. In this way, the installation can be completed without removing the contact seat.

[0032] The installation requirements for this utility model are: the gap between the bottom surface of the base 3 and the upper surface of the indicator rod 6 is less than 1.5mm, and the gap can be adjusted using the face pad adjustment plate 5. After the sensor is assembled, the circuit board is encapsulated with potting compound to improve reliability.

[0033] The working principle of this utility model is as follows: Before use, the gap needs to be calibrated. After calibration, when the indicator rod moves with the turnout, the magnetic strip 7 reaches the bottom of the sensor. The sensor can read the displacement of the magnetic strip 7 and upload the data to the acquisition unit. The acquisition unit converts the displacement data into gap values ​​and uploads them to the host computer and handheld device, so that the gap value can be read intuitively.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of implementation of the present utility model.
