Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a detection device for a wire-pulling displacement sensor. Background Technique

[0002] A wire-pulling displacement sensor, also known as a pull rope sensor, a pull rope electronic ruler, or a pull rope encoder, is an ingenious structure of a linear displacement sensor. It fully combines the advantages of an angle sensor and a linear displacement sensor, becoming a sensor with small installation dimensions, a compact structure, a large measurement stroke, and high precision. The stroke ranges from several hundred millimeters to dozens of meters. The function of the wire-pulling displacement sensor is to convert mechanical motion into an electrical signal that can be measured, recorded, or transmitted. The wire-pulling displacement sensor consists of a stretchable stainless steel rope wound around a hub, which is connected to a precision rotary sensor. The sensor can be an incremental encoder, an absolute (independent) encoder, a hybrid or conductive plastic rotary potentiometer, a synchro, or a resolver.

[0003] Currently, the device for detecting the service life of a wire-pulling displacement sensor in the prior art has a cumbersome structure, complex operation, and poor versatility, and cannot be applied to the detection operations of wire-pulling displacement sensors of different sizes. Therefore, we design a detection device for a wire-pulling displacement sensor to solve the above technical problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a detection device for a wire-pulling displacement sensor to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A lifting assembly is arranged on the left side of the top of the frame body, and a driving assembly is arranged on the right side of the top of the frame body. The lifting assembly includes a first mounting plate fixedly arranged between two cross bars on the top of the frame body. Linear bearings are respectively inserted through the four corners of the top of the first mounting plate. Telescopic rods matched with the linear bearings are arranged inside the linear bearings. The tops of the four telescopic rods are connected to the same second mounting plate. A fixing plate is arranged on the right side of the top of the second mounting plate, and a lead screw fixing seat is arranged on the left side of the top of the second mounting plate. A position display is arranged on the top of the lead screw fixing seat. A threaded sleeve is inserted through one side of the top of the first mounting plate, and the threaded sleeve is arranged through up and down.

The output shaft of the motor penetrates through the L-shaped connecting plate and is connected to a main synchronous pulley. A rotating shaft is rotatably arranged between two cross bars on the top of the frame body through a bearing seat. A wire rope wheel is sleeved on the outer center of the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the device is in use, the sensor body to be detected can be installed on the top of the fixing plate, and then the pulling rope of the sensor body is pulled out and wound around the wire rope pulley. Subsequently, the motor is started, and the output shaft of the motor drives the main synchronous pulley to rotate. Furthermore, the auxiliary synchronous pulley can be driven to rotate through the synchronous belt, and then the wire rope pulley can be driven to rotate through the rotating shaft to perform the winding and unwinding operation of the pulling rope to detect its service life. The operation is simple and convenient, time-saving and labor-saving. In particular, when detecting sensor bodies of different sizes, the device can drive the screw rod to rotate by rotating the hand wheel. Furthermore, under the action of threaded connection and the cooperation of a plurality of telescopic rods, the second mounting plate can move up and down, so as to adjust the position height of the sensor body. And through the setting of the position display, the height of the sensor body can be accurately controlled, so that when testing, the pulling ropes of sensor bodies of different sizes can be pulled out in a direction parallel to the direction of the wire outlet, improving the applicability and versatility of the device.
