DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] refer to Figures 1 to 3 The present application provides a power-assisted support detection device, which mainly includes a mounting seat, a rotation drive device 5 , a rotating shaft 6 , a rotation transmission assembly, a first fixed seat 7 , a first extension arm 8 and a second fixed seat 9 .

[0028] The mounting seat is placed on the detection platform or the detection ground, the rotating shaft 6 is placed horizontally on the mounting seat and is set at a position close to the top of the mounting seat, and a rotating drive device 5 is installed on the mounting seat below the rotating shaft 6, and the rotating drive device 5 is connected to the mounting seat by screws. A rotating transmission assembly is arranged on the mounting seat, and the rotating transmission assembly connects the rotating drive device 5 and the rotating shaft 6. The mounting seat is fixedly connected to the first fixed seat 7, the rotating shaft 6 is fixedly connected to the first extension arm 8, and the first extension arm 8 is fixedly installed with a second fixed seat 9, the first fulcrum of the power-assisting support 19 is rotatably connected to the first fixed seat 7, the second fulcrum of the power-assisting support 19 is inserted into the second fixed seat 9, and the second fulcrum of the power-assisting support 19 can be rotatably connected to the second fixed seat 9.

[0029] In addition, a screw is fixed on the top of the first fixing seat 7 to limit the axial movement of the power-assisting support 19 to prevent the power-assisting support 19 from falling out.

[0030] The sensor assembly has a movable end and a detection end. The movable end of the sensor assembly is fixedly mounted on the rotating shaft 6 through a locking member, and the detection end of the sensor assembly is fixedly mounted on the mounting seat through a locking member, and the detection end is arranged opposite to the movable end. The rotating shaft 6 drives the movable end of the sensor assembly to rotate synchronously. When the detection end detects that the movable end passes, the sensor assembly outputs a signal.

[0031] The rotary drive device 5 transmits rotary power to the rotary transmission assembly, and the rotary transmission assembly drives the rotating shaft 6 to rotate and then drives the first extension arm 8 to move. The first extension arm 8 drives the power support 19 to perform compression or release operations through the second fixed seat 9.

[0032] In addition, a sensor assembly is also provided, which is connected to the rotating shaft 6 through a locking piece and is connected to an external control unit 10 through a data cable. The sensor assembly detects the rotation angle of the rotating shaft 6 and then determines the extension or compression amount of the power support 19. The sensor assembly transmits the rotation angle parameters to the control unit 10 in real time, and the control unit 10 controls the forward and reverse movement of the rotation drive device 5.

[0033] Specifically, the mounting base includes a bottom plate 1, a left side plate 2, a right side plate 3 and a connecting plate 4. The left side plate 2 and the right side plate 3 are vertically mounted on the bottom plate 1. The left side plate 2 and the right side plate 3 are connected by the connecting plate 4 to prevent the left side plate 2 and the right side plate 3 from being deformed by force. In addition, reinforcing plates can be arranged between the bottom plate 1 and the left side plate 2, the right side plate 3 and the connecting plate 4, and between the connecting plate 4 and the left and right side plates 3.

[0034] The rotary drive device 5 is placed on the bottom plate 1, and the rotary transmission assembly is arranged on the left side plate 2 or the right side plate 3. The rotary drive device 5 preferably but not limited to adopts a servo motor, and the rotary transmission assembly can be a belt drive or a chain gear drive assembly. The following takes the servo motor + belt drive as an example to explain the driving working principle.

[0035] A servo motor is installed on the lower side of the mounting seat, and the servo motor is connected to the left side plate 2 by screws. A driving wheel 14 is installed on the rotating shaft of the servo motor, and the driving wheel 14 is connected to the motor shaft by a flat key and fixed by a set screw. A rotating shaft 6 is placed horizontally on the upper part of the left side plate 2 and the right side plate 3, and the rotating shaft 6 is connected to the left and right side plates by a bearing 17. A bearing cover plate 18 is installed on the outer side of the bearing 17 to limit the radial movement of the bearing 17. The driven wheel 15 is installed on the rotating shaft 6, connected to the rotating shaft 6 by a flat key, and fixed by a set screw.

[0036] The driving wheel 14 and the driven wheel 15 are connected by a synchronous belt 16. Under the drive of the servo motor, the driving wheel 14 drives the driven wheel 15 to rotate synchronously. In this way, by controlling the forward and reverse rotation of the servo motor, the driving wheel 14 drives the driven wheel 15, and the driven wheel 15 drives the rotating shaft 6 to rotate forward and reverse, so that the first extension arm 8 rotates, so that the first extension arm 8 compresses or releases the power support 19. Through repeated reciprocating motions, the control unit 10 monitors the torque change of the servo motor, thereby realizing the detection of the performance of the power support 19.

[0037] The sensor assembly includes: a sensor baffle 11, a sensor bracket 12 and a sensor 13. The sensor baffle 11 is installed at the end of the rotating shaft 6, and the sensor baffle 11 is connected to the end face of the rotating shaft 6 by screws. The sensor bracket 12 is installed on the outer wall of the left side plate 2 or the right side plate 3. The sensor bracket 12 is arranged on one side of the driven wheel 15, and the sensor 13 is installed on the sensor bracket 12. The sensor baffle 11 at the end of the shaft cooperates with the sensor 13, and the sensor baffle 11 can withstand the rotation of the rotating shaft 6 and then pass smoothly through the middle of the sensor 13. When the sensor 13 is working, it detects the rotation position of the rotating shaft 6 by judging whether the sensor baffle 11 passes through the middle, and outputs a signal. The control unit 10 is fixed on the bottom plate, and after converting the signal of the sensor 13, it controls the forward and reverse rotation of the motor.

[0038] In order to improve the detection efficiency, a second extension arm can be further provided on the basis of the first extension arm 8. Specifically, a third fixing seat is fixedly installed on the inner wall of the right side plate 3, a second extension arm is fixedly installed on the outer peripheral surface of the rotating shaft 6, a fourth fixing seat is installed on the second extension arm, and the two ends of the power-assisting support 19 are respectively connected to the third fixing seat and the fourth fixing seat. In order to ensure force balance, the installation directions of the first extension arm 8 and the second extension arm are opposite, that is, one extension arm is installed on the upper part of the rotating shaft 6, and the other extension arm is installed on the lower part of the rotating shaft 6. In this way, the two power-assisting supports 19 installed at the same time are installed in one direction and the other direction. Driven by the rotating shaft 6, the first extension arm 8 and the second extension arm can move at the same time. Since the power-assisting support 19 itself has a rebound force, it can offset part of the torque during the movement, so that the motor can be driven by a small torque to achieve the purpose of the test, thereby reducing the torque requirements for the motor.

[0039] The main principle of this application is: the rotating shaft is driven to make reciprocating rotational motion by the rotating drive device, driving the power support 19 to compress or release, and by monitoring the change of the motor torque, the purpose of real-time monitoring of the torque of the power support 19 is achieved. This application has low cost and occupies a small space. The torque of the power support 19 itself is offset, and the power is easy to control.

[0040] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0041] The above is a detailed introduction to the power support detection device provided by the present application. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
