[0002] An elevator is a vertical lift that serves several specific floors in a building. It has a car that runs between at least two vertical rigid guide rails or rails with an inclination angle of less than 15 degrees. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving mode. According to speed, they can be divided into low-speed elevators (below 4 meters / second), fast elevators (4 to 12 meters / second) and high-speed elevators (above 12 meters / second).

[0003] Existing portable elevator lifting acceleration testing devices usually require staff to place them at the center of the elevator to test the elevator lifting acceleration. Since the existing elevators are prone to bottom plate tilt after long-term use, the testing device cannot be placed horizontally at the center of the elevator, thereby reducing the accuracy of the testing device in testing the elevator lifting acceleration and affecting the use of the testing device in different elevator environments. Therefore, the existing portable elevator lifting acceleration testing device needs to be improved to a certain extent. Utility Model Content

[0027] The specific implementation method is as follows: by setting a level meter 5, a threaded rod 9 and a connecting rod 13, the level meter 5 is used to check the horizontality of the support plate 4, and then the threaded rod 9 cooperates with the threaded ring 10 to drive the adjustment plate 11 to adjust. At this time, the adjustment plate 11 pushes the connecting rod 13 through the sliding rod 12, so that the connecting rod 13 drives the support plate 4 to rotate along the bearing frame 2 through the fixed ring 3, and completes the horizontal adjustment of the support plate 4, which solves the problem that the existing inspection device cannot be inspected in different elevator environments, thereby facilitating the staff to inspect in different elevator environments, improving the efficiency of the inspection device in different elevator environments, and preventing the inspection device from being offset in the inspection process, thereby ensuring the accuracy of the inspection device in different elevator environments.

[0028] See also Figure 1-4The utility model provides a technical solution: a portable elevator lifting acceleration testing device, the outer wall of the threaded ring 10 is fixedly connected with an adjusting plate 11, and the two ends of the adjusting plate 11 are fixedly connected with sliding rods 12, the outer wall of the sliding rod 12 is provided with a connecting rod 13, the top of the support plate 4 is installed with a testing device body 14, and the top of the support plate 4 is provided with a control switch 15, the inner wall of the control switch 15 is installed with a connecting wire 16, and the other end of the connecting wire 16 is installed with an electric push rod 17, the top of the bottom plate 1 is installed with a supporting frame 18, the other end of the electric push rod 17 is fixedly connected with a push plate 19, and a telescopic rod 20 is installed on one side of the push plate 19, and a reset spring 21 is fixedly connected to one side of the telescopic rod 20.

[0029] The two ends of the connecting wire 16 are connected to the control switch 15 and the electric push rod 17, and the electric push rod 17 forms an integrated structure with the control switch 15 through the connecting wire 16, and the push plate 19 forms a telescopic structure through the electric push rod 17;

[0030] A support frame 18 and a push plate 19 are installed at both ends of the telescopic rod 20 , and the telescopic rod 20 forms a telescopic structure through the push plate 19 , and the return spring 21 forms a compression structure through the telescopic rod 20 .

[0031] The specific implementation method is as follows: through the control switch 15, the electric push rod 17 and the return spring 21, the two electric push rods 17 are used to push synchronously in opposite directions. At this time, the electric push rod 17 drives the push plate 19 to push the inspection device body 14 toward the center. At the same time, the telescopic rod 20 follows the return spring 21 for compression adjustment, so that the inspection device body 14 is stably limited at the center of the support plate 4, thereby facilitating the staff to quickly position the inspection device, improving the efficiency of the staff in positioning the inspection device, and at the same time ensuring the stability of the inspection device in inspecting the elevator lifting acceleration, increasing the practicality of the overall device.

[0032] Working principle: When using the portable elevator lifting acceleration test device, first place the bottom plate 1 at the center of the elevator. When the center of the elevator is tilted, the level 5 set on the top of the support plate 4 changes. At this time, the regulating valve 7 is rotated so that the regulating valve 7 drives the threaded rod 9 to rotate, so that the threaded rod 9 drives the threaded ring 10 connected to the outer wall to adjust, and then the threaded ring 10 drives the adjusting plate 11 to adjust synchronously;

[0033] At this time, the adjustment plate 11 drives the sliding rods 12 fixed at both ends to slide along the sliding grooves 8 provided through the outer wall of the adjustment frame 6, so that the sliding rods 12 push the connecting rods 13, thereby pushing the support plate 4 through the connecting rods 13 and the fixing rings 3. Since there are four fixing rings 3, and the inner walls of the two groups of fixing rings 3 are respectively connected with the bearing frame 2 and the connecting rods 13, the support plate 4 rotates along the bearing frame 2 through the fixing rings 3;

[0034] When the spirit level 5 shows that it is horizontal, stop rotating the regulating valve 7 to complete the horizontal adjustment of the support plate 4, and then place the inspection device body 14 above the support plate 4. At this time, start the control switch 15 so that the control switch 15 starts the two electric push rods 17 through the connecting line 16, so that the push plate 19 is pushed by the electric push rod 17, and then the telescopic rod 20 is telescopically adjusted by the push plate 19 in cooperation with the support frame 18, and at the same time, the telescopic rod 20 compresses and adjusts the reset spring 21, so that the inspection device body 14 is stably limited at the center of the support plate 4.
