By attaching the tensioning component 110 to the fall arrester detection device, the tensioning component 110 is enabled to tension the rope, so that the rope is prevented from slipping on the driving wheel, the torque of the driving wheel is influenced, and the detection precision is further influenced.

Specifically, the tensioning component 110 includes a tensioning wheel 111 and a mounting seat 112, the mounting seat 112 is fixed on a corresponding frame of the bearing main body 100, the tensioning wheel 111 is rotatably mounted on the mounting seat 112, and the rope is fixed on the driving assembly 300 after bypassing the tensioning wheel 111 and the driving wheel.

Thus, when the rope is connected to the roller part 310 and wound around the roller part 310, the roller part 310 performs uniform linear motion while rotating, so that the rope is uniformly wound around the outer side of the roller part 310, and the situation that the roller part is easy to overlap and disorder in the test process can be avoided.

Specifically, the first driving part 322 is a driving motor for providing a driving force to the drum part 310. The first driving part 322 may also be provided in a housing extending to a position of the drum part 310 to enclose the first driving part 322 and the drum part 310, and the linear transmission part 333 of the second driving mechanism 330 may be connected to the housing. In order to realize the adjustable and controllable rotating speed of the roller component 310, the driving motor is a speed regulating motor, and the driving motor drives the roller component 310 to rotate around the central axis of the roller component so as to wind the rope of the product to be tested.

The second driving part 332 is a driving motor for providing driving force to the linear driving part 333, and the second driving part 332 may be disposed in a housing extending to the position of the linear driving part 333 to wrap the second driving part 332 and the linear driving part 333, and a guide groove is formed in the housing to guide and match a moving block of the linear driving part 333 with the guide groove.

It can be appreciated that the driving assembly provided by the embodiment of the present utility model is configured to drive the roller member 310 to perform the linear motion while rotating by providing the second driving mechanism 330 and connecting the second driving member 332 of the second driving mechanism 330 to the roller member 310 through the linear transmission member 333. When the first driving part 322 drives the drum part 310 to rotate for rope winding, the second driving part 332 simultaneously drives the linear transmission part 333 to move, so that the linear transmission part 333 drives the installation substrate 321 and the drum part 310 and the first driving part 322 which are arranged on the installation substrate 321 to integrally conduct guiding movement, and the drum part 310 can conduct linear movement while rotating. Like this, when the rope is connected at roller part 310 to twine in roller part 310, roller part 310 carries out uniform linear motion when rotating to make the rope twine in roller part 310's outside uniformly, can avoid the roller part to appear folding rope and the condition of mess rope easily in the test process, reduces detection error, in order to improve the detection precision of the product that awaits measuring.

The second driving part 332 is mounted on the support substrate 331 through a motor mount, that is, the motor mount is fixed to the support substrate 331 through a fastener such as a screw or a bolt. The output shaft of the second driving part 332 is connected with the linear transmission part 333 through a key connection and a coupling, the linear transmission part 333 is arranged on the supporting substrate 331 and is in transmission connection with the mounting substrate 321, and the linear transmission part 333 can convert the rotation of the second driving part 332 into linear reciprocating motion of the mounting substrate 321 along the Y-axis direction.
