Description

Technical Field

[0001] This utility model relates to the field of mechanical testing equipment technology, and more specifically, to a mechanical structure testing platform. Background Technology

[0002] Structural mechanical testing is an important part of solid mechanics, studying the stress, strain, displacement, and dynamic characteristics of structures under external factors (such as loads and temperature changes). Using structural testing as a means, and employing testing instruments and equipment, the performance of structures under load is observed. By analyzing the measured data (such as load, stress, deformation, strain, temperature, amplitude, frequency, crack width, etc.), the mechanical properties of the structure are understood and mastered. The structural performance of the test object is evaluated, providing experimental basis for verifying and developing structural calculation theories.

[0003] In mechanical structural testing, destructive testing of various materials or structures is frequently required to evaluate their mechanical properties and limits. Such tests may result in the test specimens generating high-speed fragments upon failure, which can cause personal injury to operators and damage surrounding equipment and facilities. Therefore, the safety of the testing platform is a critical issue.

[0004] Existing testing platforms are typically equipped with simple guardrails or barriers, but these devices are often structurally simple and offer poor protection, failing to adequately cushion the impact of debris and posing significant safety hazards and inconvenience to testing operations. Furthermore, during testing, flying debris may scatter in all directions, not only creating safety risks but also increasing the difficulty of post-test cleanup.

[0005] In view of the above problems, there is an urgent need for a mechanical structure testing platform with complete protective functions, which can effectively collect the debris generated during the test while ensuring the safety of personnel and equipment, so as to facilitate subsequent analysis and processing. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a mechanical structure testing platform. By setting up protective mechanisms around the testing platform, the test sample is fully shielded and protected, preventing it from scattering and injuring people or damaging other equipment after being damaged. In addition, a flexible buffer component is provided to effectively buffer and capture the splashed sample fragments, making it convenient to collect the fragments.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A mechanical structure testing platform includes a frame and a protective mechanism. The bottom of the frame is fixedly installed on a base. A test bench is installed inside the frame. A hydraulic cylinder is installed inside the top of the frame. A protective mechanism adapted to the test bench is provided on the upper side of the test bench. A hydraulic pump is installed on the left side of the frame. The hydraulic pump is connected to the hydraulic pump through a hydraulic pipe.

[0009] The protective mechanism includes a protective housing, flexible buffer units, a switchable cover, angle irons, and a storage box. The protective housing is made of stainless steel plate, with its bottom placed on a test bench. Its left and right sides are fixedly connected to the frame by multiple sets of angle irons and bolts. The front side of the protective housing is equipped with an openable switchable cover. The top of the protective housing has a through groove adapted to the hydraulic cylinder. Multiple sets of flexible buffer units are evenly pasted on the inner wall of the protective housing. The bottom of the rear side of the protective housing has a slot, inside which a detachable storage box is installed, and a handle is installed on the outer side of the storage box.

[0010] Furthermore, the flexible buffer unit includes a fixed shell, a flexible buffer net, a secondary buffer layer and a primary buffer layer. The fixed shell is a box-shaped structure with an opening on the front side, and the interior is provided with a flexible buffer net, a primary buffer layer and a secondary buffer layer from the outside to the inside. The flexible buffer net has two layers.

[0011] Furthermore, two sets of double-sided adhesive are affixed to the rear side of the fixing shell, and the fixing shell is attached to the inner wall of the protective box by means of the double-sided adhesive.

[0012] Furthermore, the flexible buffer net is made of woven rope and has a thickness of 3mm; the primary buffer layer is made of sponge material and has a thickness of 20-30mm; and the secondary buffer layer is made of silicone material and has a thickness of 10-20mm.

[0013] Furthermore, the switch cover is made of transparent tempered glass, and a layer of transparent silicone pad with a thickness of 10mm is pasted on the inner side.

[0014] Furthermore, the bottom of the protective box is composed of three parts: the left side is a ramp, and the right end of the ramp is in contact with the test bench; the middle part is an open structure for connecting to the test bench; the right side is a recessed groove, and the upper surface of the groove is flush with the upper surface of the test bench, wherein the storage box is disposed in the groove.

[0015] Furthermore, the left end of the switch cover is hinged to the protective box via a hinge, and the right end is detachably connected to the protective box via a self-locking buckle.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, by setting up a protective mechanism around the test bench, can provide all-round shielding and protection for the test samples on the test bench, effectively preventing the test samples from being damaged and splashing everywhere, causing injury to people or damage to other equipment, and greatly improving the safety of the test process.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] Example:

[0030] like Figures 1 to 7 As shown, a mechanical structure testing platform includes a frame 1 and a protective mechanism 2. The bottom of the frame 1 is fixedly installed on the base 6. A test bench 4 is installed inside the frame 1. The test bench 4 is used to fix the test sample and cooperate with the hydraulic pump 3 to conduct mechanical tests on the test sample. A hydraulic cylinder 5 is installed inside the top of the frame 1. The hydraulic cylinder 5 is a hydraulic input unit used to provide power support for the test and meet the needs of different mechanical tests. The upper side of the test bench 4 is equipped with a protective mechanism 2 that is adapted to it, used to shield and protect the test sample to prevent sample fragments from flying. A hydraulic pump 3 is installed on the left side of the frame 1. The hydraulic pump 3 is connected to the hydraulic pump 4 through a hydraulic pipe. The hydraulic pump 3 is a power output source used to provide hydraulic power to the hydraulic pump 3.

[0031] The protective mechanism 2 includes a protective housing 21, a flexible buffer unit 22, a switchable cover 23, angle irons 24, and a storage box 26. The protective housing 21 is made of stainless steel plate, and its bottom is placed on the test bench 4. Multiple sets of angle irons 24 and bolts are used to fix the protective housing 21 to the frame 1 on both sides. The angle irons 24 and bolts secure the protective housing 21, resulting in a stable structure that effectively blocks flying debris during the test, providing reliable protection for the test operation. The front side of the protective housing 21 is equipped with an openable cover 23. The openable design facilitates the placement and removal of test samples by operators, while also providing protection during the test. The top of the protective housing 21 has a through groove 25 adapted to the hydraulic cylinder 5. Multiple sets of flexible buffer units 22 are evenly attached to the inner wall of the protective housing 21. These flexible buffer units 22 effectively buffer the impact force of fragments. When fragments impact the protective housing 21, the flexible buffer units 22 absorb energy and disperse the impact force, reducing damage to the protective housing 21 and preventing secondary breakage. A slot 27 is located at the bottom of the rear side of the protective housing 21. A removable storage box 26 is installed inside the slot 27 to store broken sample fragments, facilitating subsequent cleaning. A handle 261 is installed on the outer surface of the storage box 26, making it easy for operators to disassemble and clean the fragments inside. This design solves the problem that existing test platforms are usually equipped with simple guardrails or baffles, but these devices are often simple in structure, have poor protective effects, and cannot effectively buffer the impact force of fragments, causing significant safety hazards and inconvenience to the test operation. Furthermore, during the test, splashed fragments may scatter everywhere, not only creating safety hazards but also increasing the difficulty of post-test cleanup.

[0032] In this embodiment, the flexible buffer unit 22 includes a fixed shell 221, a flexible buffer net 222, a secondary buffer layer 223, and a primary buffer layer 224. The fixed shell 221 is a box-shaped structure with an opening at the front, and the flexible buffer net 222, the primary buffer layer 224, and the secondary buffer layer 223 are arranged sequentially from the outside to the inside. The flexible buffer net 222 has two layers, which can intercept and disperse fragments at different levels, providing better blocking for smaller fragments. The flexible buffer unit 22 adopts a layered buffer structure, which can gradually consume the energy generated by the fragment impact. When a fragment impacts, it first contacts the flexible buffer net 222 for initial energy dispersion and buffering; then the impact force is transmitted to the primary buffer layer 224 for further energy absorption; finally, the secondary buffer layer 223 plays a final buffering and stabilizing role, effectively reducing the direct impact force of the fragment on the protective housing 21.

[0033] In this embodiment, two sets of double-sided adhesive 225 are affixed to the rear side of the fixing shell 221, and the fixing shell 221 is attached to the inner wall of the protective box 21 by the double-sided adhesive 225. Using double-sided adhesive 225 to attach the fixing shell 221 to the inner wall of the protective box 21 is a simple and quick operation, requiring no complicated installation tools or steps, which can greatly shorten installation time, improve production efficiency, and facilitate disassembly and replacement of the flexible buffer unit 22 after damage.

[0034] In this embodiment, the flexible buffer net 222 is made of braided rope and has a thickness of 3mm. The woven rope flexible buffer net 222 has a certain degree of elasticity and flexibility, and can deform to some extent upon impact, thereby dispersing and absorbing part of the impact force. The primary buffer layer 224 is made of sponge material and has a thickness of 20-30mm. Sponge has good elasticity and energy absorption characteristics, and can quickly compress and deform upon impact, absorbing a large amount of energy. Its porous structure allows it to effectively disperse the impact force during the buffering process, reducing pressure on subsequent buffer layers. The secondary buffer layer 223 is made of silicone material and has a thickness of 10-20mm. Silicone has high elasticity, wear resistance, and chemical corrosion resistance, and can quickly return to its original shape while absorbing the remaining impact force, maintaining the stability of the buffering performance.

[0035] In this embodiment, the switch cover 23 is made of transparent tempered glass. The transparency allows operators to directly observe the test conditions inside the protective chamber 21 without opening the cover, facilitating real-time monitoring of the test process, timely detection of problems, and timely adjustments, thus improving the convenience and efficiency of the test. Tempered glass has high strength and impact resistance, capable of withstanding significant impacts. Furthermore, a 10mm thick transparent silicone pad 231 is adhered to the inner surface, protecting the inner surface of the switch cover 23 from direct impacts from fragments that could scratch the inner surface and affect observation.

[0036] It should be noted that the bottom of the protective box 21 consists of three parts. The left part is a ramp 211, and the right end of the ramp 211 is in contact with the test bench 4. The ramp 211 plays a guiding role, guiding the broken fragments to slide to the right onto the test bench 4, which is convenient for centralized cleaning later. The middle part is an open structure for connecting to the test bench 4. The right part is a recessed groove 212, and the upper surface of the groove 212 is flush with the upper surface of the test bench 4. The storage box 26 is located in the groove 212. The groove 212 is used to place the storage box 26, which can prevent the storage box 26 from protruding and affecting the test.

[0037] In this embodiment, the left end of the switch cover 23 is hinged to the protective box 21 via a hinge, and the right end is detachably connected to the protective box 21 via a self-locking latch. The hinge enables the opening and closing of the switch cover 23, and the self-locking latch enables the quick connection and separation of the cover and the protective box 21. It can also remain locked after the cover is closed to prevent the cover from opening due to accidental collisions or vibrations, thus ensuring the safety and reliability of the test.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
