DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 5, an elevator traction wheel rope groove wear detection fixture, including a traction wheel 1, a fixed block 2 is arranged on one side of the traction wheel 1, and adjustment bolt seats 3 are welded on both ends of the outer side of the fixed block 2, and a support screw 4 is rotatably connected to the inner side of the adjustment bolt seat 3, and a docking block 5 is rotatably connected to one end of the support screw 4, and the outer surface of one end of the two docking blocks 5 is in contact with the outer surface of the traction wheel 1, in order to ensure that the detection mechanism is always perpendicular to the outer surface of the traction wheel 1, so as to prevent the detection mechanism from being skewed due to the skew of the fixed block 2 Contraction or extension causes deviation in the detection result. A groove bottom rod slide groove 6 is provided in the middle of the inner side of the fixed block 2. A rebound groove 7 is provided at the bottom end of the groove bottom rod slide groove 6 on the inner side of the fixed block 2. Both ends of the rebound groove 7 penetrate the fixed block 2 and a groove wall rod slide groove 8 is provided. A bottom groove 9 is provided at the bottom end of the fixed block 2. A groove bottom rod 10 is slidably embedded in the inner side of the groove bottom rod slide groove 6. In order to detect the groove bottom of the rope groove of the traction wheel 1, an extension block 13 is slidably embedded in the inner side of the rebound groove 7 at the bottom end of the groove bottom rod 10. The extension block 13 The two ends are respectively slidably embedded in the inner sides of the two groove wall rod slide grooves 8, a guide rod 11 is welded on the inner side of the rebound groove 7, an extension block 13 is sleeved on the outer side of the guide rod 11, a vertical rebound spring 12 is sleeved on the outer side of the guide rod 11, one end of the vertical rebound spring 12 is connected to the inner wall of the rebound groove 7, in order to detect the groove wall of the rope groove of the traction wheel 1, the other end of the vertical rebound spring 12 is connected to the outer side surface of one end of the extension block 13, and both ends of the outer side of the extension block 13 are provided with transverse slide grooves 14, and the transverse slide grooves A transverse rebound spring 15 is connected to the inner side of 14, one end of the transverse rebound spring 15 is slidably embedded in the inner side of the transverse slide groove 14 with a transverse limit block 16, the inner bottom end of the transverse slide groove 14 passes through the extension block 13 to open an extension groove 17, the bottom end of the extension block 13 is connected to a magnet rod 18, and a magnetic handwriting board 19 is installed at the bottom end of the fixed block 2. The bottom ends of the two magnet rods 18 are in contact with the top surface of the magnetic handwriting board 19, in order to show the route trajectory of the groove bottom rod 10 and the transverse limit block 16 when they are displaced.

[0023] Working principle: First, the operator inserts the fixed block 2 into the rope groove of the traction wheel 1, and the operator presses the fixed block 2 again. During this period, the bottom rod 10 that slides inside the fixed block 2 and is embedded in the bottom rod slide groove 6 will shrink inside the bottom rod slide groove 6 due to the pressing of the fixed block 2. At that time, the operator rotates the two supporting screws 4, and the supporting screws 4 will rotate and move inside the adjusting bolt seat 3, while driving the docking block 5 that is connected to one end to move until it fits on the outer surface of the traction wheel 1. Then the operator starts the motor that drives the traction wheel 1 to rotate, so that the traction wheel 1 can rotate slowly. At that time, the operator holds the fixed block 2, so that during the rotation of the traction wheel 1, the two docking blocks 5 can always fit on the outer surface of the traction wheel 1, so that it can be ensured that the fixed block 2 is always perpendicular to the outer surface of the traction wheel 1, and the bottom rod 10 will always fit on the bottom of the rope groove of the traction wheel 1.

[0024] During this period, if an irregular area appears on the bottom surface of the rope groove of the traction wheel 1, the groove bottom rod 10 will retract or extend again due to the change in the distance from the bottom of the rope groove of the traction wheel 1, and at the same time drive the extension block 13 welded at its bottom end to move together, and the extension block 13 will drive the lateral limit block 16 slidably embedded in it to move, and the lateral limit block 16 will drive the two magnet rods 18 welded at the bottom end to slide vertically on the top of the magnetic handwriting board 19, during which the lateral limit blocks 16 slidably embedded in the lateral slide grooves 14 opened on both sides of the extension block 13 through the lateral rebound spring 15 will fit on the traction wheel 1, if there is an irregular area on the rope groove wall surface of the traction wheel 1, the two lateral limit blocks 16 will be driven by the lateral rebound spring 15 in the lateral slide groove 14 to shrink or extend, and at the same time drive the magnet rod 18 welded at the bottom end of the lateral limit block 16 to slide horizontally in the extension groove 17 penetrating the inner bottom end of the extension block 13, and the two magnet rods 18 will slide horizontally at the top of the magnetic handwriting board 19. After the traction wheel 1 rotates one circle, the wear condition of the rope groove of the traction wheel 1 can be known by observing the traces on the magnetic handwriting board 19. This design can speed up the detection efficiency.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
