Description

Technical Field

[0001] The utility model relates to the technical field of elevator footrest testing, in particular to an elevator footrest strength testing device. Background Technique

[0002] The elevator footrest is an important safety component in the elevator system. It is located below the gap between the landing sill and the car door sill of the elevator. Its main function is to prevent passengers' feet from stepping into the hoistway when the elevator stops at a non-leveling position, avoiding shearing injuries. The design and installation quality of the footrest are directly related to the safety performance of the elevator. Therefore, strength testing is usually carried out during the production of the footrest to ensure its quality.

[0003] After retrieval, the text with the publication number "CN215910229U" mentions that "This application relates to the field of strength testing. More specifically, it relates to a strength testing device for gaskets, which includes a bottom plate, a dynamometer, a support rod, a box body, a fixing mechanism, a lifting mechanism, and a driving mechanism. The dynamometer is installed on the bottom plate, and a pressure testing rod is slidably arranged on the dynamometer. The top end of the pressure testing rod is a free end. The bottom end of the support rod is fixedly connected to the bottom plate, and the fixing mechanism is used to fix the box body on the support rod. The lifting mechanism includes a gear, a rack, a rotating shaft, and a holding rod. The two ends of the rotating shaft are rotatably connected to the two side walls of the box body. The gear is sleeved on the rotating shaft and fixedly connected to the rotating shaft. One end of the holding rod is fixedly connected to one end of the rotating shaft. The driving mechanism includes a guide rod, a lifting block, and a spring. The bottom end of the guide rod is fixedly connected to the box body. The lifting block is fixed to the top end of the rack, and the top end of the spring is connected to the guide rod, and the bottom end of the spring is connected to the lifting block." It reduces the manual labor intensity by mechanically detecting the strength of the gasket. However, the elevator footrest is in different temperature environments during use, while the traditional testing device usually only tests the elevator footrest in a single environment and cannot test the performance of the elevator footrest under different environmental conditions.

[0004] Therefore, we provide an elevator footrest strength testing device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an elevator footrest strength testing device to solve the problems raised in the above background technique.

[0015] 1. Through the setting of the load-bearing strength detection mechanism, the electric control telescopic rod drives the limit clamping plate to perform a certain limit clamping on the elevator footrest, preventing the elevator footrest from tilting, ensuring the stability of the elevator footrest test.

[0016] 2. By setting the temperature control simulation component, start the temperature control air conditioner to heat or cool the elevator footrest from the bottom through the temperature adjustment port, changing the temperature of the elevator footrest to simulate the situation of the elevator footrest in different temperature environments, improving the comprehensiveness of the test. Through the setting of the spring telescopic rod, when the elevator footrest bends downward, the spring telescopic rod will also be stressed and contract, driving the temperature adjustment port to lower, ensuring the normal test of the elevator footrest.

[0025] The load-bearing strength testing mechanism 2 includes a limit component 21 and a pressure testing component 22. The limit component 21 is installed at the top of the device main body 1, and the pressure testing component 22 is arranged above the device main body 1.

[0026] Furthermore, the limit component 21 includes an electric control telescopic rod 211, a limit clamping plate 212, a support backing plate 213, and an auxiliary roller 214. The electric control telescopic rods 211 are installed on the left and right sides at the top of the device main body 1. The limit clamping plate 212 is connected to the inner card slot of the electric control telescopic rod 211. Place the elevator footrest to be tested on the device main body 1, and drive the limit clamping plate 212 through the electric control telescopic rod 211 to perform a certain limit clamping on the elevator footrest, preventing the elevator footrest from tilting and ensuring the stability of the elevator footrest test.

[0027] Furthermore, the surface of the device main body 1 is fixedly connected with a support backing plate 213, and the end of the support backing plate 213 is pin-connected with an auxiliary roller 214. The elevator footrest is supported by the auxiliary roller 214, enabling the elevator footrest to deform better during the compression test and ensuring the accuracy of the test results.

[0028] Furthermore, the pressure testing component 22 includes a support top platform 221, a main shaft controller 222, a lifting main shaft 223, a mounting frame 224, a detection indenter 225, and a pressure sensor 226. The support top platform 221 is welded to the rear end of the device main body 1. The main shaft controller 222 is installed at the top of the support top platform 221. The lifting main shaft 223 is fixedly connected to the bottom end of the main shaft controller 222. The mounting frame 224 is installed at the bottom end of the lifting main shaft 223. The detection indenter 225 is connected to the inner card slot at the bottom end of the mounting frame 224. The detection indenter 225 is driven by the lifting main shaft 223 to move up and down to press down on the elevator footrest, causing the elevator footrest to undergo a bending test to test the strength of the elevator footrest.

[0029] Furthermore, a pressure sensor 226 is installed inside the detection indenter 225. The pressure sensor 226 is electrically connected to the main shaft controller 222. While testing the elevator footrest, the pressure applied to the elevator footrest is detected by the pressure sensor 226, and the data is transmitted to an external device at the same time, facilitating the user to understand the strength of the elevator footrest. At the same time, a certain threshold value can be set for the pressure sensor 226.

[0031] Please refer to Figure 1 and Figure 4As shown, compared with the first comparative example, as another implementation mode of the present utility model, a temperature control simulation component 3 is installed at the front end of the device main body 1. The temperature control simulation component 3 includes a temperature control air conditioner 31, a temperature adjustment port 32, a connecting hose 33 and a spring telescopic rod 34. The temperature control air conditioner 31 is installed at the front end of the device main body 1, and the temperature adjustment port 32 is installed at the inner top end of the device main body 1. Start the temperature control air conditioner 31 to heat or cool the elevator footrest from the bottom through the temperature adjustment port 32, change the temperature of the elevator footrest, so as to simulate the situation of the elevator footrest in different temperature environments and improve the comprehensiveness of the test.

[0032] Furthermore, a connecting hose 33 is fixedly connected to the inner side of the temperature adjustment port 32, and spring telescopic rods 34 are welded to the left and right ends of the temperature adjustment port 32. Through the setting of the spring telescopic rods 34, when the elevator footrest bends downward, the spring telescopic rods 34 will also be stressed and contracted, driving the temperature adjustment port 32 to descend, ensuring the normal test of the elevator footrest.

[0033] Working principle: When in use, first step, install this device at the place where it is needed, and then place the elevator footrest to be tested on the device main body 1.

Second step, drive the detection indenter 225 to lift and lower through the lifting main shaft 223 to press down the elevator footrest, so as to perform a bending test on the elevator footrest to test the strength of the elevator footrest. At the same time, support the elevator footrest through the auxiliary roller 214, so that the elevator footrest can deform better when being pressed, ensuring the accuracy of the test results. Third step, while testing the elevator footrest, detect the pressure applied to the elevator footrest through the pressure sensor 226, and at the same time transmit the data to the external device, which is convenient for the user to understand the strength of the elevator footrest. At the same time, a certain threshold value can be set for the pressure sensor 226. After detecting that the pressure reaches the qualified line, transmit the signal to the main shaft controller 222 to stop the lifting main shaft 223, prevent danger caused by excessive testing, and improve the safety of the test. Fourth step, start the temperature control air conditioner 31 to heat or cool the elevator footrest from the bottom through the temperature adjustment port 32, change the temperature of the elevator footrest, so as to simulate the situation of the elevator footrest in different temperature environments and improve the comprehensiveness of the test.
