[0021] Preferably, the metal sheet is a spring steel sheet.

[0028] The following is combined with Figure 1-4 This application is described in further detail.

[0029] The embodiment of the present application discloses a rolling guide shoe roller life test device. Figure 1 and Figure 2 The rolling guide shoe roller life test device includes a bracket 1, a rotating wheel 2, a connecting frame 3 and a load-bearing frame 4.

[0030] like Figure 1 and Figure 2 As shown, the bracket 1 is fixedly arranged on a horizontal plane such as the ground, and the bracket 1 can provide a stable installation platform for the connecting frame 3 and the rotating wheel 2; illustratively, the bracket 1 is a metal frame.

[0031] In an embodiment of the present application, the wheel 2 is rotatably connected to the bracket 1 through a structure or device such as a rotating seat. The wheel 2 is vertically arranged at the lower part of the bracket 1. A first driving member 5 is provided on one side of the wheel 2. The output end of the first driving member 5 is detachably connected to the wheel 2, and the fixed end of the first driving member 5 is fixedly connected to the bracket 1. The first driving member 5 is used to drive the wheel 2 to rotate so that the wheel 2 simulates the relative movement of the guide rail during the movement of the elevator, and reproduces the dynamic contact state between the roller 8 and the guide rail during the operation of the elevator. The first driving member 5 drives the wheel 2 to rotate to provide stable power output for the wheel 2, ensure the rotation speed and direction of the wheel 2, and thus reproduce the dynamic characteristics of the guide rail during the operation of the elevator; exemplarily, the first driving member 5 is a motor.

[0032] like Figure 1 and Figure 3 As shown, the connecting frame 3 is hinged to the bracket 1 , and the connecting frame 3 is arranged on the upper part of the bracket 1 . The connecting frame 3 is used to be rotatably connected to the roller 8 to drive the roller 8 to abut against or separate from the rotating wheel 2 .

[0033] In the embodiment of the present application, the connecting frame 3 is fixedly provided with an adjusting member 6, which is rotatably connected to the roller 8. The adjusting member 6 is used to change the distance between the roller 8 and the connecting member. The adjusting member 6 can change the distance between the roller 8 and the connecting member, thereby controlling the initial contact gap between the roller 8 and the guide rail, ensuring that the contact state between the roller 8 and the runner 2 during the test can reflect the actual situation in the operation of the elevator.

[0034] Exemplarily, the connecting frame 3 is a metal frame, and the adjusting member 6 is a hand-cranked screw lift. The adjusting member 6 can convert the rotational motion into linear motion, thereby achieving fine-tuning of the distance between the roller 8 and the connecting frame 3, and ultimately controlling the initial contact gap between the roller 8 and the guide rail, and the connecting frame 3 changes the contact state between the roller 8 and the wheel 2 by rotating around the bracket 1.

[0035] like Figure 1 and Figure 3 As shown, the load-bearing frame 4 includes a connecting rod 41 and a receiving plate 42, one end of the connecting rod 41 is fixedly connected to the connecting frame 3, and the end of the connecting rod 41 away from the connecting frame 3 is fixedly connected to the receiving plate 42, the connecting rod 41 ensures the reliability of pressure transmission, and the receiving plate 42 can quickly adjust the pressure conditions according to different test requirements, so the load-bearing frame 4 can bear weights of different weights, simulate the different pressure conditions between the roller 8 and the guide rail during the operation of the elevator, and improve the existing guide shoe roller test device in simulating the pressure between the roller 8 and the guide rail. For example, the connecting rod 41 and the receiving plate 42 are both alloy rods and metal plates with fixed weight. The actual pressure of the load-bearing frame 4 during the test should be reduced by the weight of the connecting rod 41 and the bearing plate.

[0036] In an embodiment of the present application, the bracket 1 is fixedly provided with a second driving member 7, and the output end of the second driving member 7 is arranged opposite to the connecting frame 3. The second driving member 7 is used to extend or contract the output end to drive the connecting frame 3 to rotate around the axis or reset the second driving member 7. The second driving member 7 can realize the abutment or separation between the roller 8 and the rotating wheel 2, shortening the test preparation time and adjustment time, and improving the test efficiency; exemplarily, the second driving member 7 is a cylinder.

[0037] Please note that, please refer to Figure 1 and Figure 4 The bracket 1 is provided with a sliding groove 11, and a sliding block 12 for linear motion is provided in the sliding groove 11. The sliding block 12 is slidably connected to the bracket 1, and the sliding block 12 is hinged to the connecting frame 3; the linear motion of the sliding block 12 drives the connecting frame 3 to move, which can simulate the dynamic contact and separation process between the roller 8 and the guide rail during the operation of the elevator, and simulate the different contact working conditions between the roller 8 and the guide rail during the operation of the elevator; for example, by changing the relative position of the roller 8 and the runner 2, it can simulate situations including but not limited to elevator rail gnawing.

[0038] In an embodiment of the present application, the sliding groove 11 is provided with a metal sheet 13, one end of the metal sheet 13 is fixedly connected to the inner wall of the sliding groove 11, and the other end of the metal sheet 13 is fixedly connected to the sliding block 12. The metal sheet 13 is arranged in an arc shape to limit the position of the sliding block 12; the elastic limiting function of the metal sheet 13 can prevent the sliding block 12 from excessively moving in the sliding groove 11, thereby avoiding damage to the connecting frame 3 or the roller 8 due to the sliding block 12 exceeding the predetermined range.

[0039] Exemplarily, the metal sheet 13 is a spring steel sheet, and the elastic properties of the spring steel sheet enable it to adapt to shock and vibration under dynamic working conditions, thereby ensuring the reliability of the simulated elevator operation.

[0040] like Figure 4 As shown, the side walls on both sides of the sliding groove 11 are provided with L-shaped grooves 14, and the two L-shaped grooves 14 are symmetrically arranged. The two L-shaped grooves 14 are used to place the metal rod 15 and limit the positions of the two ends of the metal rod 15. The metal rod 15 is used to abut against the metal sheet 13 to limit the deformation of the metal sheet 13, thereby limiting the movement of the sliding block 12, and ultimately limiting the movement of the connecting frame 3.

[0041] For example, in the embodiment of the present application, two groups of metal sheets 13 , metal rods 15 and two L-shaped grooves 14 are provided, both groups are provided in the sliding groove 11 , and the two groups are respectively located on both sides of the sliding block 12 .
