Description

Technical Field

[0001] This utility model relates to the technical field of elevator foot protection board strength testing equipment, and in particular to an elevator foot protection board impact strength testing equipment. Background Technology

[0002] Elevator foot guards are thin metal plates installed under the sills of elevator landing doors and car doors. Their main function is to protect passengers' feet from elevator shearing injuries. Foot guards are typically made of smooth and hard materials, such as thin metal plates, to ensure their strength and durability. To ensure that the strength of elevator foot guards meets standards, specialized testing equipment is usually used to test them.

[0003] An existing elevator footboard strength testing device (announcement number: CN221528235U) uses a linear drive component to read the deformation of the footboard when the pressure on it is 300N. However, when testing elevator footboards on-site, the environment is complex and may generate significant impact and vibration, making it difficult to maintain the overall stability of the device. This makes it difficult for staff to adjust the device for testing, thus affecting the accuracy of the test data. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an elevator foot protection plate impact strength testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An elevator foot protection plate impact strength testing device includes a support base, a receiving plate, and a strength tester body. A shock-absorbing pad is fixedly installed inside the support base, and a rubber protrusion is fixedly installed at the upper end of the shock-absorbing pad. The receiving plate is connected to the top of the support base by fasteners. A reinforcing frame is provided below the support base, and a buffer spring is fixedly installed between the reinforcing frame and the bottom of the support base. A sleeve is fixedly installed at the upper end of the receiving plate, and a lifting column is embedded inside the sleeve. Bolts are movably installed on the side wall of the sleeve. A slide rail is fixedly installed at the top of the lifting column, and a mounting seat is movably installed on the slide rail. A sliding strip is fixedly installed at the bottom of the strength tester body, and a positioning hole is opened on the sliding strip. A positioning pin is embedded in the side wall of the mounting seat.

[0007] As a further embodiment of this utility model, the positioning pin passes through the positioning hole, a screw block is fixedly provided at the bottom of the mounting base, a lead screw is movably installed inside the slide rail, a side support foot is fixedly provided on the reinforcing frame, and an anti-slip pad is fixedly provided at the bottom of the side support foot.

[0008] As a further embodiment of this utility model, the slide bar is slidably connected to the mounting base, the screw block is threadedly connected to the lead screw, the side support legs are evenly distributed on the reinforcing frame, and the top of the side support legs is fixedly connected to the support base.

[0009] As a further embodiment of this utility model, a button is provided on one side of the slide rail, one end of the lead screw is fixedly connected to the button, and an insert is fixedly provided on one side of the receiving plate.

[0010] As a further embodiment of this utility model, the end of the lead screw away from the button is connected to the inner wall of the slide rail via a rotating shaft, and the buffer springs are evenly distributed at the bottom of the support base.

[0011] As a further embodiment of this utility model, the rubber protrusions are evenly distributed on the shock-absorbing pad, a telescopic tube is provided on one side of the sleeve, and the two ends of the telescopic tube are respectively fixedly connected to the receiving plate and the slide rail, and a control panel is fixedly installed on the side wall of the main body of the strength tester.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When conducting impact strength tests on elevator foot plates, a reinforcing frame is installed at the bottom of the support base, with side supports at each of the four corners of the frame. This strengthens the support for the main body of the strength testing instrument and prevents the support base from shifting during testing. When subjected to vibration during the test, multiple buffer springs absorb and disperse some of the vibration energy. Simultaneously, a shock-absorbing pad is placed between the support base and the bearing plate, with rubber protrusions evenly distributed on the pad. The interaction between the shock-absorbing pad and the multiple rubber protrusions further effectively absorbs and disperses some of the vibration energy, thereby improving the stability of the main body of the strength testing instrument. When testing other parts of the foot plate, [further details are needed]. With the help of the telescopic tube, the operator only needs to pull the lifting column to slide upward along the inner wall of the sleeve, thereby adjusting the height of the strength tester body. Finally, the bolt is turned to tighten the lifting column, fixing the height of the strength tester body. The horizontal position of the strength tester body can be adjusted by pushing the slide bar. Then, the positioning pin is pushed to insert into the corresponding positioning hole. Finally, by turning the button, the screw is rotated, causing the screw block to move back and forth along the inner wall of the slide rail. At the same time, the strength tester body on the mounting base moves horizontally in another direction, so that the strength tester body can perform strength tests on different parts of the foot plate, thereby improving the accuracy of the test data.
