Description

Technical Field

[0001] The utility model belongs to the technical field of monorail hanging speed measuring trolley detection, and specifically relates to a speed measuring trolley detection device. Background Art

[0002] In order to ensure the safety of monorail crane operation, the speed of the monorail crane needs to be limited. Usually, a speed measuring trolley is installed on the monorail crane. The speed measuring trolley includes a mechanical centrifugal speed limiter and an electronic encoder. When the running speed of the monorail crane exceeds the set speed of the speed measuring trolley, the locomotive is controlled to brake and stop.

[0003] After the centrifugal speed limiter of the speed measuring trolley has been running for a period of time, the speed limit may be inaccurate, so it is necessary to test and calibrate the speed of the centrifugal speed limiter. The existing detection method requires the entire speed measuring trolley to be removed from the track and the speed to be measured by a dedicated speed measuring device, which is time-consuming and laborious.

[0006] In some possible embodiments, a rotor is fixedly connected to the output shaft of the driving member, and the rotor is used to cooperate with a socket provided on the centrifugal speed limiter to drive the centrifugal speed limiter to rotate.

[0007] In some possible embodiments, the driving member is configured as a motor.

In the utility model, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0020] refer to Figure 1-Figure 3 The present embodiment provides a speed measuring trolley detection device, which is used to directly detect the speed measuring trolley in the existing monorail crane on the track without removing it.

[0021] join Figure 1-Figure 3 In a possible embodiment, the detection device includes a mounting frame 10, which includes a mounting plate 14, a connecting rod 11 and a drive seat 12. The mounting plate 14 is provided with a mounting hole, and the mounting plate 14 is fixedly mounted on the housing of the speed measuring vehicle by fasteners such as screws. The connecting rod 11 is vertically fixed on the mounting plate 14, and the drive seat 12 is connected to the end of the connecting rod 11, and the drive seat 12 is arranged in front of the centrifugal speed limiter 43.

[0022] In some possible embodiments, a driving member 20 is fixedly connected to the driving seat 12. Optionally, the driving member 20 is fixed to the driving member 20 by fasteners such as screws and the driving member 20 is arranged toward the rotation center of the centrifugal speed limiter 43 and connected to the rotating outer shell of the centrifugal speed limiter 43.

[0023] refer to Figure 2 and Figure 3 The centrifugal speed limiter 43 is installed on the speed measuring trolley 40. The rotating shell of the centrifugal speed limiter 43 is hinged on the hinge shaft 42 through the support ear. The centrifugal speed limiter 43 is connected with a spring 41. The centrifugal speed limiter 43 is also connected with a speed measuring wheel, which is used to abut against the running track. It is used to run with the car on the track and play the role of speeding the monorail crane. One end of the spring 41 is fixed to the shell of the speed measuring trolley 40, and the other end is connected to the centrifugal speed limiter 43. The spring 41 is used to make the speed measuring wheel of the centrifugal speed limiter 43 close to the track.

[0024] In some possible embodiments, an adjustment mechanism 30 is further installed on the mounting frame 10, and the adjustment mechanism 30 is used to abut against the centrifugal speed governor and control the centrifugal speed governor to rotate around its hinge shaft 42 to a set angle so that the speed measuring wheel of the centrifugal speed governor 43 is off the track.

[0025] That is, in this embodiment, the centrifugal speed governor 43 is lifted to a certain height by the adjusting mechanism 30, so that the speed measuring wheel of the centrifugal speed governor 43 is separated from the track without removing the spring 41, and the driving member 20 is controlled to rotate the housing of the centrifugal speed governor 43 when the speed measuring wheel is separated from the track. The rotation speed of the driving member is a preset speed, and at the preset speed, if the lever of the centrifugal speed governor can be thrown out, it means that the centrifugal speed governor 43 is qualified, otherwise, the centrifugal speed governor 43 needs to be maintained.

[0026] In some possible embodiments, a rotor 21 is fixedly connected to the output shaft of the driving member 20, and the rotor is used to cooperate with the socket provided on the centrifugal speed limiter 43 to drive the centrifugal speed limiter to rotate. Specifically, a slot is provided on the end surface of the shell of the centrifugal speed limiter 43, and a plug block matching the slot is correspondingly provided on the rotor 21. By matching the plug block with the slot, when the driving member is started, the rotor 21 drives the centrifugal speed limiter 43 to rotate.

[0027] Optionally, the driving member 20 may be an electric motor, a hydraulic motor or a pneumatic motor, or other components that can drive the rotary head to rotate.

[0028] In some possible embodiments, the adjustment mechanism 30 includes an adjustment rod, a first end of the adjustment rod is set as a threaded rod 33, a screw hole matching the threaded rod 33 is set on the mounting frame 10, and a rod head 31 is set at the second end of the adjustment rod, and the rod head 31 is used to abut against the centrifugal speed limiter 43. That is, by rotating the matching length of the threaded rod 33 and the screw hole on the adjustment rod, it abuts against the centrifugal speed limiter 43 and pushes the centrifugal speed limiter 43 to rotate a certain angle around its hinge shaft 42 to completely get out of the track.

[0029] Furthermore, an adjusting nut 32 is fixed on the adjusting rod, and the adjusting rod is rotated by rotating the adjusting nut 32 with a wrench.

[0030] Furthermore, a rotating handle is provided on the adjusting rod, and the rotation of the adjusting rod is controlled by the rotating handle.

[0031] In some possible embodiments, a support seat 13 is further provided on the mounting plate 14 , and the support seat 13 is used to support the adjusting rod.

[0032] For example, when this embodiment is used, after the monorail crane stops, the mounting plate 14 on the mounting frame is mounted on one side of the outer shell of the speed measuring trolley, and then the adjusting rod is threadedly connected to the mounting plate 14, and then the driving member 20 is mounted on the driving seat 12, and the rotating head 21 provided on the driving member 20 is matched with the slot on the centrifugal speed limiter 43. The adjusting rod is rotated with a wrench, and the adjusting rod will push the centrifugal speed limiter on the speed measuring trolley upward for a short distance, so that the speed measuring wheel is off the track. The pneumatic driving member 20 also adjusts the speed of the driving member 20, and the driving member 20 drives the speed measuring wheel on the centrifugal speed limiter 43 to rotate together. When the speed is adjusted to the required speed, observe whether the trigger lever of the centrifugal speed limiter pops out to trigger the action of the overspeed protection valve group, thereby achieving the function of verifying the reliability of the overspeed protection system.
