[0021] See also Figure 1-4 , the utility model provides a technical solution for an auxiliary device for elevator hydraulic buffer reset test:

[0022] Example 1:

The test frame 2 is arranged on the top of the test bench 1, and the load assembly 14 is arranged at the bottom of the test frame 2.

A conveying rack 10 is provided on the top of the guide plate 5. Two vertical bars 9 are fixedly installed on the bottom of the conveying rack 10. The distance between the conveying rack 10 and the test bench 1 can be adjusted to facilitate the transportation of the hydraulic buffer and save the energy of carrying the hydraulic buffer. Through this structure, the next hydraulic buffer to be reset tested can be placed on the top of the conveying rack 10 in advance. After the hydraulic buffer is unloaded after the test, the hydraulic buffer on the top of the conveying rack 10 can be quickly transported to the inside of the test bench 1 for subsequent testing, thereby improving the efficiency of the auxiliary device.

[0024] Example 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, the positions of the two side baffles 11 are corresponding to each other, a handrail 12 is fixedly installed on one side of the transport frame 10, a plurality of first reinforcement rods 15 are provided on the top of the test bench 1, and a plurality of second reinforcement rods 16 are provided on the bottom of the test frame 2, one end of the plurality of second reinforcement rods 16 is respectively fixedly connected to one end of the plurality of first reinforcement rods 15, and the diameters of the plurality of second reinforcement rods 16 are all larger than the diameters of the plurality of first reinforcement rods 15. The utility model is an auxiliary device for the reset test of the hydraulic buffer of an elevator, which is provided with a side baffle 11, a handrail 12, an arc block 3 and a support shaft 4. The support shaft 4 is fixed on one side of the arc block 3, thereby ensuring the stability of the guide plate 5. The two side baffles 11 are distributed on both sides of the top of the transport frame 10, thereby increasing the height of the protection of the hydraulic buffer.

[0026] Working principle: The reset test of the elevator hydraulic buffer is a key step to ensure that the hydraulic buffer can work normally and reliably in the elevator system. The main function of the hydraulic buffer is to absorb and buffer the kinetic energy of the elevator car during the descent process, prevent the car from violently impacting at the bottom and other terminal positions, and ensure the safety of passengers. The auxiliary device used for the reset test of the elevator hydraulic buffer mainly includes a hydraulic test bench and a load simulation device to simulate the weight of the elevator car to ensure the working condition of the test buffer under the actual load. The hydraulic test bench can place the hydraulic buffer. There is only one hydraulic test bench, and the next buffer can only be loaded after one buffer completes the test. The subsequent buffer loading will take a long time. Other buffers need to occupy additional space while waiting for testing, resulting in a waste of resources. For this reason, it is particularly important to design an auxiliary device for the reset test of the elevator hydraulic buffer. Place the hydraulic buffer on the top of the conveyor frame 10, push the conveyor frame 10 inward, and drive the two displacement blocks 8 to move inward at one end of the corresponding support rod 7, so that the conveyor frame 10 and the test bench 1 can be adjusted. The distance between the hydraulic buffers facilitates the transportation of the hydraulic buffers, saving the energy of carrying the hydraulic buffers. Through this structure, the next hydraulic buffer to be reset and tested can be placed on the top of the transport rack 10 in advance. After the hydraulic buffer is unloaded after the test, the hydraulic buffer on the top of the transport rack 10 can be quickly transported to the inside of the test bench 1 for subsequent testing, which improves the efficiency of the auxiliary device. The load component 14 can simulate the weight of the elevator car, apply the weight of the elevator car to the hydraulic buffer, observe the reaction of the buffer, ensure that the test is carried out within the specified pressure range, and record the performance data of each stage. After the pressure is applied, the reset process of the hydraulic buffer is observed and the time it takes to return to the initial state is checked. The support shaft 4 is fixed on one side of the arc block 3, which ensures the stability of the guide plate 5. The two side baffles 11 are distributed on both sides of the top of the transport rack 10, increasing the height of the protection for the hydraulic buffer. The handrails 12 are convenient for the staff to hold to control the position of the transport rack 10. After pushing the hydraulic buffer, the hydraulic buffer can be moved from the position of the transport slot 13 to the inside of the test bench 1.
