[0043] Figure 1 This is a schematic diagram of the structure of a ring crane brake testing system in one embodiment of this application; Figure 2 for Figure 1 A top view of the ring brake test system in the illustrated embodiment.

[0044] See Figure 1-2 The ring crane brake testing system provided in one embodiment of this application includes a ring crane brake 100 and a testing device 200.

[0045] The ring brake 100 includes a first direction (i.e., Figure 2 In the first direction A), two brake arms 110 are arranged opposite to each other and spaced apart, and the two brake arms 110 are along a second direction perpendicular to the first direction (i.e., Figure 1 Brake plates 120 are provided on the same side in direction B). The testing device 200 includes a vertical plate 210 and a pressure sensor (not shown) disposed on the vertical plate 210. At least one of the two brake plates 120 is configured to adjust the distance between the two brake plates 120 in the first direction to clamp or release the vertical plate 210. The pressure sensor is configured to detect the clamping force applied to the vertical plate 210 by the two brake plates 120.

[0046] The aforementioned ring crane brake testing system, by setting up a testing device 200 including a vertical plate 210 and a pressure sensor mounted on the vertical plate 210, allows the pressure sensor to detect the clamping force applied by the two brake plates 120 to the vertical plate 210. Thus, the operator can determine the braking force of the two brake plates 120 based on the clamping force detected by the pressure sensor, and compare the braking force with a preset braking force range to adjust or repair the ring crane brake 100, ensuring the braking force is within the preset range, thereby improving the braking reliability of the ring crane brake 100.

[0047] It should be noted that during the actual operation of the ring brake 100, the component to be braked is located between the two brake plates 120. When the two brake plates 120 clamp the component to be braked, the component is in a braking state, that is, the component is fixed relative to the two brake plates 120. When the two brake plates 120 release the component to be braked, the component is in an unbraked state, that is, the component rotates relative to the two brake plates 120 about a rotation axis parallel to the first direction. The braking force is the force applied to the component by the two brake plates 120 when they clamp it. Therefore, as long as the dimension of the vertical plate 210 in the first direction is the same as the dimension of the component to be braked in the first direction, the clamping force applied by the two brake plates 120 to the vertical plate 210 during the test can be made equal to the braking force applied by the two brake plates 120 to the component to be braked during actual operation. Thus, the braking force can be directly obtained through the clamping force detected by the pressure sensor.

[0048] In the actual operation of the ring crane brake 100, the component to be braked is the ring crane starter.

[0049] In order to enable at least one of the two brake plates 120 to adjust the spacing between the two brake plates 120 in the first direction, in some embodiments, in combination Figure 1-2 As shown, the two brake arms 110 include a first brake arm 111 and a second brake arm 112. The ring brake 100 also includes a drive member 130 connected to the first brake arm 111. The testing device 200 also includes a controller electrically connected to the drive member 130, the controller being configured to control the drive member 130 to move the first brake arm 111 along a first direction toward or away from the second brake arm 112. Thus, by including the drive member 130 connected to the first brake arm 111 in the ring brake 100 and including the controller electrically connected to the drive member 130 in the testing device 200, the controller can control the drive member 130 to move the first brake arm 111 relative to the second brake arm 112, thereby causing the brake plate 120 connected to the first brake arm 111 to move along the first direction toward or away from the other brake plate 120, thereby achieving automatic adjustment of the distance between the two brake plates 120 along the first direction.

[0050] Optionally, the drive unit 130 includes an electromagnet 131, and the second brake arm 112 has an armature 150 disposed opposite to the electromagnet 131 along a first direction. The controller is configured to control the energization of the electromagnet 131, so that the electromagnet 131 drives the first brake arm 111 to move along the first direction toward the side closer to the armature 150. Thus, by setting the drive unit 130 to include an electromagnet 131 and the armature 150 disposed in the second brake arm 112, when the controller controls the energization of the electromagnet 131, the electromagnet 131 becomes magnetic, thereby creating a magnetic attraction between the electromagnet 131 and the armature 150. The electromagnet 131 drives the first brake arm 111 connected to the electromagnet 131 to move along the first direction toward the side closer to the armature 150, thereby driving the brake plate 120 connected to the first brake arm 111 to move along the first direction toward the side closer to the other brake plate 120, so that the two brake plates 120 clamp the upright plate 210.

[0051] Understandably, when the controller controls the electromagnet 131 to not be energized, the electromagnet 131 is not magnetic, the electromagnet 131 releases the armature 150, the first brake arm 111 moves along the first direction away from the armature 150, and drives the brake plate 120 connected to the first brake arm 111 to move along the first direction away from the other brake plate 120, so that the two brake plates 120 release the upright plate 210.

[0052] Optionally, such as Figure 1 As shown, the first brake arm 111 and the second brake arm 112 are rotatably connected about a first axis a. A drive member 130 is connected to the side of the first brake arm 111 away from the brake plate 120, driving the side of the first brake arm 111 away from the brake plate 120 to move towards or away from the side of the second brake arm 112 away from the brake plate 120. The first axis a extends in a direction perpendicular to both the first and second directions. This fixes the first brake arm 111 and the second brake arm 112 relative to each other in a direction parallel to the first axis a, thus limiting the movement of the first brake arm 111 relative to the second brake arm 112 to rotation about the first axis a. This improves the alignment accuracy between the two brake plates 120 and makes the detection of clamping force more accurate.

[0053] Optionally, combined Figure 1-2As shown, the portion of the first brake arm 111 located between the brake plate 120 and the electromagnet 131 is rotatably connected to the portion of the second brake arm 112 located between the brake plate 120 and the armature 150 around the first axis a. Thus, when the electromagnet 131 is energized, the side of the first brake arm 111 with the electromagnet 131 moves along the first direction toward the side of the second brake arm 112 with the armature 150, causing the brake plate 120 connected to the other side of the first brake arm 111 to move along the first direction away from the other brake plate 120, increasing the distance between the two brake plates 120 in the first direction, and the ring brake 100 does not brake. When the electromagnet 131 is de-energized, the side of the first brake arm 111 with the electromagnet 131 moves in the first direction away from the side of the second brake arm 112 with the armature 150. This causes the brake plate 120 connected to the other side of the first brake arm 111 to move in the first direction closer to the other brake plate 120, reducing the distance between the two brake plates 120 in the first direction, thus braking the ring brake 100. Therefore, when the electromagnet 131 is not energized, the two brake plates 120 are in a normally closed state, improving the service life and reliability of the workpiece.

[0054] In some embodiments, such as Figure 1-2 As shown, the ring brake 100 also includes a brake disc 140, which is located between the side of the first brake arm 111 away from the brake plate 120 and the side of the second brake arm 112 away from the brake plate 120. A drive member 130 is disposed within the brake disc 140. Thus, by providing the brake disc 140 to accommodate the drive member 130 and enabling the first brake arm 111 to contact the second brake arm 112 via the brake disc 140, the contact area between the first brake arm 111 and the second brake arm 112 is increased.

[0055] In some embodiments, the testing device 200 also includes a display screen electrically connected to the pressure sensor. The display screen is used to display the magnitude of the clamping force applied to the upright plate 210 by the two brake plates 120 detected by the pressure sensor, so that the operator can obtain the magnitude of the clamping force detected by the pressure sensor by reading the reading on the display screen, thereby improving the convenience of reading.

[0056] In some embodiments, the testing device 200 includes two distance sensors, which are respectively disposed on opposite sides of the upright plate 210 in the first direction. The distance sensors are used to detect the distance between adjacent brake plates 120 and the upright plate 210 in the first direction. It should be noted that during the actual operation of the ring crane brake 100, when the ring crane brake 100 is not braking, that is, when the two brake plates 120 are released from the brake, the distance between each brake plate 120 and the upright plate 210 in the first direction must be within a preset distance range. Therefore, by setting two distance sensors on opposite sides of the upright plate 210 along the first direction to detect the distance between adjacent brake plates 120 and the upright plate 210 in the first direction, the operator can compare the distance detected by the distance sensors with the preset distance range, and adjust or repair the ring crane brake 100 according to the deviation between the two, so that the distance detected by the test sensors is within the preset distance range, thereby further improving the working reliability of the ring crane brake 100.

[0057] In other embodiments, the testing device 200 further includes a measuring tool that extends between any brake arm 110 and the upright plate 210 to measure the distance between the brake arm 110 and the upright plate 210 in a first direction. This allows the operator to obtain the distance between the brake arm 110 and the upright plate 210 at different positions along the first direction by extending the measuring tool at different locations between the brake arm 110 and the upright plate 210, ensuring that the distance between the brake arm 110 and the upright plate 210 at any position is within a preset range. This prevents the brake arm 110 from being skewed in the first direction, which could cause the distance between the brake arm 110 and the upright plate 210 at different positions to fail to meet requirements.

[0058] Alternatively, a feeler gauge can be used as the measuring tool.

[0059] In some embodiments, such as Figure 1-2 As shown, the testing apparatus 200 also includes an operating table 220, which has a support surface for placing the ring brake 100, and a vertical plate 210 is provided on the support surface. Thus, by setting up the operating table 220 to place the ring brake 100, and after the ring brake 100 is mounted on the operating table 220, the ring brake 100 can be fixed relative to the vertical plate 210 (when the first brake arm 111 is not moving relative to the second brake arm 112), thereby facilitating the testing of the ring brake 100.

[0060] Specifically, the ring brake 100 is detachably connected to the control panel 220 via fasteners.

[0061] In some embodiments, the testing device 200 further includes a walking mechanism (not shown) connected to the operating table 220. The walking mechanism is used to drive the operating table 220 to move along a first direction or a second direction, so that the operating table 220 can be moved to different positions for convenient use.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
