Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ground anchor structures, specifically to a ground anchor structure for ladder strength testing. Background Technology
[0002] Ladder strength testing anchors are devices used to test the stability and safety of ladders under different load conditions. They are typically used to assess the maximum force or load conditions of ladders in practical applications.
[0003] The existing technology still has the following areas for improvement: the existing ground anchors used for ladder strength testing cannot flexibly change the direction of force applied to the ladder when assessing the maximum stress of the ladder, and the test results are relatively simple. If a more comprehensive assessment of the maximum stress of the ladder is required, multiple sets of ground anchors need to be set up, which increases the testing cost and requires more time to adjust and fix the positions of multiple sets of ground anchors, thus reducing the testing efficiency. Utility Model Content
[0004] To address the aforementioned problems in the existing technology, this utility model provides a ground anchor structure for ladder strength testing. This structure enables the device to flexibly adjust the direction of force applied to the ladder during strength testing through the cooperation of the base and pulley assembly. It eliminates the need for additional ground anchors and repositioning and fixing of the entire device, thereby reducing testing costs and improving testing efficiency.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A ground anchor structure for ladder strength testing includes a base, a pulley assembly and a steel rope, wherein the base has multiple positioning holes in the middle.
[0007] The pulley assembly includes a pulley, a connecting plate, and a second bolt. The connecting plate is U-shaped, and multiple through holes located on the same straight line are provided on the vertical sections on both sides of the U-shape of the connecting plate. The connecting plate is connected to the pulley through the through holes and the second bolt. The multiple positioning holes are evenly distributed and located on the same straight line.
[0008] Preferably, the steel rope is slidably connected to the pulley.
[0009] Preferably, one end of the base is provided with a groove, and the other end of the base is provided with an anti-collision pad.
[0010] Preferably, multiple fixing blocks are provided on both sides of the base, and the multiple fixing blocks are evenly distributed.
[0011] Preferably, the fixing block is connected to a first bolt.
[0012] Preferably, a protruding block is provided on the U-shaped horizontal section of the connecting plate, and a hook is provided on one side of the protruding section of the connecting plate.
[0013] Preferably, the hook end of the hook is on the same horizontal plane as the side end face of the protruding block.
[0014] Preferably, the anti-collision pad is concave, and the base matches the concave part of the anti-collision pad.
[0015] The beneficial effects of this utility model are as follows:
[0016] (1) By setting up a base, the technical effect that can be achieved is that the base has multiple positioning holes in the middle, the multiple positioning holes are evenly distributed and located on the same straight line, which makes it easy to accurately locate the position of the ladder during each stress test, reduce the error during different tests, and more accurately assess the maximum stress of the ladder. The other end of the base is equipped with a collision pad to prevent workers from accidentally hitting the base and getting injured during operation.
[0017] (2) By setting up a base, pulley assembly and steel rope, the technical effect that can be achieved is that the hook setting makes it easy for the pulley assembly to hook into the positioning hole of the base. By adjusting the installation of the pulley assembly in different positions on the base and cooperating with the steel rope, the direction of force applied to the ladder during the strength test can be flexibly adjusted. There is no need to add an extra ground anchor or reposition and fix the entire device, which reduces the test cost and improves the test efficiency. Attached Figure Description
