Description

Technical Field

[0001] The utility model relates to the technical field of safety rope testing, in particular to a strength detection device for a fire safety rope. Background Art

[0002] A fire safety rope is a special rope used for rescue and escape. It is usually made of high-strength fiber materials such as polyamide fiber or aramid fiber. Fire safety ropes are widely used in buildings, high-rise buildings, industrial facilities, ships and other places that require high-altitude rescue and escape. Before the fire safety rope leaves the factory, it needs to be tested for strength with the help of a tensile testing machine to ensure its safety and reliability. The working principle of the tensile testing machine is based on Newton's second law and Hooke's law. It determines the mechanical properties of the material by applying force and measuring deformation. Since the safety rope will swing outward and produce debris when it breaks during the test, it is necessary to carry out testing and protection work.

[0003] In the related art, during the use of a tensile testing machine, the safety rope is generally tested by clamping it with a clamp and applying tension to it to stretch it, and the force during the detection process is monitored and recorded by a sensor to perform the test.

[0004] However, currently, during the use of the tensile testing machine, since the tensile testing machine is generally in an open configuration, the safety rope may break during the test and may easily injure the user by mistake, thus affecting the safety of the safety rope detection.

[0036] Specifically, the working process or working principle of the strength detection device of a fire safety rope is as follows: when using it for the first time, first hold the collecting seat 10 and place it on the inner side of the stand 2, then hold the collecting box 12 and place it on the top of the auxiliary rod 14, and make the guide bar 15 enter the guide groove 16, and then push the collecting box 12 to move to the rear side. When the collecting box 12 drives the auxiliary port 13 to be parallel with the auxiliary rod 14 during the movement, move the collecting box 12 downward to install the collecting box 12 on the inner side of the stand 2 and fall on the top of the collecting seat 10. At this time, the guide bar 15 also enters the auxiliary port 13 and disengages from the auxiliary groove. During the installation process of the collecting seat 10 and the collecting box 12, the collecting seat 10 and the collecting box 12 are affected by the position of the dislocation port 17, and the collecting seat 10 and the collecting box 12 will not directly contact the chuck 4. During the safety rope detection process, after the safety rope to be detected is clamped and connected by the chuck 4, the hand-held force-applying bar 6 applies a translational force to the protective plate 5 to close the blocking operation on both sides of the stand 2. At this time, the connecting seat 9 follows the protective plate 5 to move inside the connecting groove 8, and the protective plate in the translation process is controlled by the connecting bar 7. 5 performs guiding and stabilizing work, and drives the magnetic strip 18 to contact the magnetic strip 19, and performs magnetic attraction positioning work on the moved protective plate 5. When the internal driving components of the stand 2 work, the lifting platform 3 and the clamp 4 perform a tension test on the safety rope. When the safety rope breaks due to the test tension, the protective plate 5 performs a breaking and blocking work on the safety rope, so that the breaking process of the safety rope is carried out on the inner side of the protective plate 5 and the stand 2, ensuring the safety of the safety rope detection. At the same time, the collection box 12 collects the debris after the safety rope breaks. When the collection box 12 is When the safety rope debris collected inside the collection box 12 needs to be cleaned, the collection box 12 is moved upward by hand and a forward force is applied to the collection box 12. As the collection box 12 moves upward, the auxiliary rod 14 moves inside the auxiliary port 13. When the guide bar 15 at the top of the auxiliary rod 14 is aligned with the guide groove 16, the guide bar 15 enters the guide groove 16 to guide the collection box 12. The collection box 12 can be disassembled and cleaned, which is convenient for disassembling the collection box 12 during use while avoiding collision between the collection box 12 and the chuck 4.

[0037] It should be noted that the stand 2, lifting platform 3 and chuck 4 are all devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
