Description

Technical Field

[0001] This utility model relates to the field of elevator speed governor testing, and in particular to a portable elevator speed governor testing device. Background Technology

[0002] Elevator speed governors are usually important components in elevator safety protection systems. Their main function is to monitor and control the speed of the elevator car to prevent accidents. Elevator speed governors usually require regular maintenance and testing. When conducting tests, portable elevator speed governor testing devices are typically used. Portable elevator speed governor testing devices are usually used to detect and test the performance of elevator speed governors.

[0003] Existing portable elevator speed governor testing devices typically include a portable test case, a controller, a tester, and connecting cables. The portable test case includes an upper case and a lower case. The controller is embedded inside the lower case, and the tester and connecting cable are placed inside the lower case. The upper case is rotatably connected to the lower case, allowing the upper case to be configured as a flip-top. A locking mechanism is also provided to secure the upper and lower cases.

[0004] The connecting cable connects the tester to the controller. The drive motor on the tester rotates the test roller, which contacts the speed governor wheel, causing the speed governor wheel to rotate and gradually accelerate to the speed governor's operating speed. When the speed governor issues an overspeed signal, the tester records the rotational speed at that time and, through on-site observation and confirmation, ensures that the speed governor can promptly issue a signal and cut off the power supply circuit when the elevator overspeeds, thereby ensuring the safe operation of the elevator. After use, the connecting cable is usually manually wound up by the staff before being placed inside the test box. However, this method can lead to the connecting cable becoming tangled and twisted during the movement of the portable test box, requiring additional cable management and affecting subsequent direct use of the connecting cable. Therefore, it is necessary for the portable elevator speed governor testing device to organize and store the connecting cable. Utility Model Content

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides, for example Figure 1-5 The image shows a portable elevator speed limiter testing device.

[0038] Example 1

[0039] The system includes a lower housing 1, a tester 3, a soft pad 4, and an auxiliary mechanism 5. The lower housing 1 facilitates the placement of the tester 3 and connecting wires 6. The soft pad 4 provides soft support for the tester 3, facilitating buffering and protection. The tester 3 includes a drive motor and a test roller. The testing principle is that the output end of the drive motor is connected to the test roller, which drives the test roller to rotate. The test roller contacts the speed limiter wheel, causing the speed limiter wheel to rotate and gradually accelerate to the speed limiter's operating speed. When the speed limiter issues an overspeed signal, the controller 9 records the rotational speed at that time and, through on-site observation and confirmation, ensures that the speed limiter can promptly issue a signal and cut off the power supply circuit when the elevator overspeeds, thereby ensuring the safe operation of the elevator. The lower housing 1... The top is rotatably connected to the upper housing 2, which helps to cover the interior of the lower housing 1 to shield and protect the tester 3, etc. The controller 9 is installed inside the lower housing 1. The controller 9 is convenient to connect to the connecting line 6. The connecting line 6 is connected to the tester 3, so that the tester 3 can be tested and controlled. The tester 3 is located inside the lower housing 1, and the connecting line 6 is provided on the side of the tester 3. The two ends of the connecting line 6 are respectively connected to the first connector 7 and the second connector 8. The first connector 7 and the second connector 8 are convenient to connect to the controller 9 and the tester 3. The soft pad 4 is fixedly connected to the interior of the lower housing 1, and the tester 3 is located on the soft pad 4. The auxiliary mechanism 5 is located inside the lower housing 1. The auxiliary mechanism 5 is used to wind up and store the connecting line 6.

[0040] Furthermore, the auxiliary mechanism 5 includes a first wheel 51, a second wheel 52, and a fixed shaft 53. The first wheel 51 and the second wheel 52 facilitate support for the two limiting members and also limit the connecting wire 6 between them, preventing the stored connecting wire 6 from moving freely. The fixed shaft 53 facilitates connection and support for the two annular plates 54 and allows the hollow tube to rotate outside it, thereby providing rotational support for the first wheel 51 and the second wheel 52 for winding the connecting wire 6. The first wheel 51 is located in the lower housing. Inside 1, the second wheel 52 is located on top of the first wheel 51. A hollow tube is fixedly connected between the second wheel 52 and the first wheel 51. The connecting wire 6 is wound around the outside of the hollow tube. The fixed shaft 53 is located inside the hollow tube and rotates through the middle of the first wheel 51 and the second wheel 52. Annular plates 54 are fixedly connected to both ends of the fixed shaft 53, which helps to limit the installation position of the first wheel 51 and the second wheel 52, allowing the first wheel 51 and the second wheel 52 to rotate between the two annular plates 54.

[0041] Furthermore, the auxiliary mechanism 5 also includes a limiting member and a mounting member. The adjacent limiting members are located outside the first wheel 51 and the second wheel 52, respectively. The adjacent limiting members are used to lock the position of the first connector 7 and the second connector 8, respectively. The mounting member is located at the bottom of one of the annular plates 54. The mounting member is used to fix one of the annular plates 54 to the lower housing 1.

[0042] Specifically, the limiting components include a fixed frame 55 and a limiting plate 56. The fixed frame 55 facilitates the placement of the first connector 7 and the second connector 8 within it, thereby limiting the connection between the first connector 7 and the second connector 8. The limiting plate 56 helps to shield the interior of the fixed frame 55, providing anti-detachment protection for the first connector 7 or the second connector 8 located inside the fixed frame 55, preventing the first connector 7 or the second connector 8 from detaching at will. Adjacent fixed frames 55 are respectively fixedly connected to the exterior of the first wheel 51 and the second wheel 52, and adjacent fixed frames 55 are respectively covered on the exterior of the first connector 7 and the second connector 8. The limiting plate 56 is located on the side of the fixed frame 55.

[0043] More specifically, the limiting components also include a sliding plate 57 and a guide plate 58. The sliding plate 57 and the guide plate 58 facilitate the sliding connection between the limiting plate 56 and the fixed frame 55. The sliding plate 57 and the guide plate 58 are damped to the inner walls of the slide groove and the guide groove. By attaching rubber pads to the inner walls of the slide groove and the guide groove, the limiting plate 56 will not slip off at will. The sliding plate 57 is fixedly connected to the side of the limiting plate 56. The side of the fixed frame 55 is symmetrically provided with slide grooves that are adapted to the sliding plate 57. The guide plate 58 is fixedly connected to the side of the sliding plate 57. The side of the inner wall of the slide groove is provided with a guide groove that is adapted to the guide plate 58.

[0044] Example 2

The base 59 is conveniently installed at the bottom of the lower housing 1, facilitating its use. The positioning post 510 supports the annular plate 54, thereby facilitating the positioning connection between the first wheel 51 and the base 59 for assembly. The first magnet 511 and the second magnet 512 magnetically fix the positioning post 510, allowing the connecting wire 6 to be stored and fixed by the first wheel 51 and the second wheel 52 before direct installation inside the lower housing 1 for easy access and use. The base 59 is installed inside the lower housing 1, and the positioning post 510 is fixedly connected to the bottom of one of the annular plates 54. The positioning post 510 is slidably inserted into the inner cavity of the base 59.
