Slide rail with rope displacement sensor

Release date: June 24, 2019 Hits: 198

In the well-known field of technology, pull rope Displacement sensor It's a straight line Displacement sensor The smart integration in the structure fully combines the advantages of angle displacement sensor and linear displacement sensor, and becomes an excellent sensor with compact structure, long measuring stroke, small installation space and high-precision measurement. Its stroke ranges from 200 mm to 20000 mm, with analog current of 4-20 mA, analog voltage of 0-5 V or 0-10 V and pulse a, B, z-phase digital output, which meets the requirements of large-scale Travel, high-precision signal requirements, its application is very wide, especially in the track device, when the sliding seat is in different moving distance, the Rope displacement sensor Send out the corresponding electrical signal, input to the central control system, easy to take corresponding measures, especially in the multimedia application.

Contents of utility model

The technical problem to be solved by the utility model is to make full use of it Rope displacement sensor It can provide a kind of cable slide which can play a flexible buffer role in stopping, avoid excessive impact load, and improve the stability of the slide rail operation.

The utility model has the advantages of simple structure, reasonable design, no common mechanical locking mechanism for stopping, but full utilization Rope displacement sensor For the accuracy of slide seat position detection, combined with electromagnetic field, the PLC control panel will receive the result before the sliding seat reaches the designated position and braking Rope displacement sensor The transmitted electric signal judges that the distance is close and needs to be braked. However, through the preset program, the electromagnetic coil device is electrified at this time, which makes the electromagnetic coil device and the magnet block repel each other. Through the mutually repulsive magnetic field, it plays the role of flexible buffer, which makes the speed of the sliding seat decrease greatly. When the sliding seat is about to stop after deceleration, it is still transmitted through the pull wire The electric signal transmitted by the sensor, the PLC control panel reversely energizes the electromagnetic coil, which makes the electromagnetic coil and the magnet block attract each other, which can make the braking of the sliding seat more stable and reliable, and will not cause small sliding, which plays the role of braking. At the same time, in this process, it can realize full-automatic control and effectively ensure the stability of the slide rail.

Specific implementation mode

Now the utility model is further explained in detail in combination with the attached drawings. These drawings are simplified schematic diagrams, and only illustrate the basic structure of the utility model in a schematic way, so they only show the composition related to the utility model.

The preferred embodiment of the pull rail of the utility model as shown in Fig. 1 and Fig. 2 includes a slide rail body 1, on which a slide seat 2 is installed and at the head end of the slide rail body 1 Rope displacement sensor Unit 3, Rope displacement sensor The pull wire of device 3 is fixed at the tail of slide seat 2, and the electromagnetic coil device 5 controlled by PLC control panel 4 is installed at the tail end of slide rail body 1, and the PLC control panel 4 is connected with external power supply 9, and Rope displacement sensor The signal of device 3 is input to PLC control panel 4. Elastic buffer devices 6 are respectively arranged on both sides of electromagnetic coil device 5 and on the left and right side ends of slide rail body 1. The elastic buffer device 6 has a wedge block 61 hinged with the side end of the slide rail body 1, and a buffer spring 62 is arranged between the side end of the slide rail body 1 and the wedge block 61, The side of the electromagnetic coil device 5 towards the slide seat 2 is coated with polyurethane foam pad 7, and the side of the bottom of the slide seat 2 facing the tail end of the slide rail body 1 is provided with a magnet block 8.

Taking the above ideal implementation example of the utility model as an inspiration, through the above description, relevant staff can make various changes and modifications within the scope of not deviating from the technical idea of the utility model. The technical scope of the utility model is not limited to the contents in the description, and the technical scope must be determined according to the scope of claims.
