[0002] A lift is a type of lifting machinery used to transport people or objects vertically. It also refers to equipment for vertical transportation in logistics systems such as factories and automatic warehouses. In addition to transporting goods at different heights, it is also widely used in high-altitude installation and maintenance operations.

[0003] When the lifting platform body is lifted up and down relative to the platform frame, the bottom of the platform body is usually guided and supported by four guide rails and sliders to assist the smooth up and down lifting of the platform body. However, the slide rails and sliders are not provided with corresponding devices for detecting the movement stroke of the slider, which makes it inconvenient to detect the movement stroke of the slider and to assist in further precise control of the lifting height of the lifting platform.

The setting of the limit block 2 9 allows the front frame 8 to be limitedly installed at the bottom of the slide rail 1, and the front frame 8 will not fall off downward. The setting of the clamping block 13, the screw hole 3 14, the screw hole 1 6 and the bolt 7 allows the front frame 8 to be assembled and connected with the rear frame 3. The further setting of the screw hole 4 15 can further limit and fix the end frame structure composed of the rear frame 3 and the front frame 8 at the bottom of the slide rail 1, so that the end frame structure will not move up and down and loosen, so as to stably set and use the distance sensor 11;

[0025] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, further, a screw hole 10 is opened in the middle position of the front frame 8, and a distance sensor 11 is screwed and connected inside the screw hole 10. A rubber ring 12 is fixedly connected around the upper end of the distance sensor 11. Among them, through the setting of the rubber ring 12, when the bottom end of the slider 2 is connected to the front end of the distance sensor 11 after the slider 2 is reset downward, the front end of the distance sensor 11 can be flexibly buffered and protected, so as to prevent the distance sensor 11 from being damaged by pressure. When in use, the display matched with the distance sensor 11 needs to be fixedly installed at the corresponding position on the lifting platform frame by screws, and the distance sensor 11 is connected to the display accordingly, and the display is connected to an external power supply. Because the utility model is mainly a design description of the detection part of the distance sensor 11, the display used for displaying its data is not specifically shown in the figure.

[0026] In the present embodiment, the utility model is provided with an end frame structure assembled by a rear frame 3 and a front frame 8 at the bottom end of the slide rail 1, and a distance measuring sensor 11 is screwed and installed on the front frame 8, which is simple and convenient to disassemble and assemble, and easy to replace and repair. In the process of the lifting platform body rising and falling, the distance measuring sensor 11 can emit a light beam upward, and the light beam touches the obstacle slider 2 to form a reflected light beam and is received by the distance measuring sensor 11, and then converted into an electrical signal for processing and analysis, so as to obtain the movement travel distance of the slider 2, so as to assist in further precise control of the lifting height of the lifting platform.

[0027] The use process and working principle of the utility model are as follows: the display matched with the distance sensor 11 is fixedly installed at the corresponding position on the lifting platform frame by screws, and the distance sensor 11 is connected to the display accordingly, and the display is connected to the external power supply. Among them, since the utility model is mainly a design description of the detection part of the distance sensor 11, the display used for displaying its data is not specifically shown in the figure;

[0028] When in use, the lifting platform is started by an external power supply. During the process of the lifting platform body being lifted up and down, the slider 2 slides up and down relative to the slide rail 1. At the same time, the distance measuring sensor 11 can emit a light beam upward. After the light beam touches the obstacle slider 2 that moves up and down, a reflected light beam is formed and received by the distance measuring sensor 11, which is then converted into an electrical signal and processed and analyzed by the built-in system of the display. The data is displayed by the display, and the movement travel distance of the slider 2 can be obtained, so as to further assist in the precise control of the lifting height of the lifting platform and make the lifting platform at the corresponding height.
