Description

Technical Field

[0001] This utility model relates to the field of performance testing technology, specifically to an engineering testing device. Background Technology

[0002] In engineering testing, different material performance testing equipment is used to test the performance of different materials in order to obtain engineering parameters, thereby ensuring that ideal engineering materials are used in engineering construction.

[0003] The bending test device can detect the bending degree of steel plates and reinforcing bars. However, the adaptability of the test platform is lacking when testing reinforcing bars and steel plates. For example, during the test, the applied pressure will cause the position of the test object to shift, resulting in poor safety of the test object during the pressure bending test and the risk of damaging the test object. Utility Model Content

[0004] The purpose of this invention is to provide an engineering testing device that can at least solve some of the defects in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an engineering testing device, comprising a placement component for placing an object to be tested, the placement component including a limiting structure for finding the edge of the object to be tested and limiting the edge, the limiting structure having a placement position for placing the object to be tested.

[0006] Furthermore, the limiting structure includes a base and several protruding rods. Each protruding rod has a limiting ring at one end facing the base. A spring is installed on the limiting ring in the same direction as the length of the protruding rod. The base has a movable groove for the protruding rod and the spring to be inserted. When the spring is compressed into the movable groove, the limiting ring is locked in the movable groove.

[0007] Furthermore, it also includes a slide rail, the base being a slide block, the slide block being provided with a slide bar, and the slide bar being slidably disposed on the slide groove of the slide rail.

[0008] Furthermore, the groove is a dovetail groove, and the slide bar is a dovetail protrusion that engages with the dovetail groove.

[0009] Furthermore, the base is provided with a locking structure that can be locked onto the slide rail.

[0010] Furthermore, there are at least two sets of placement components, which cooperate to place the object under test, and the area between the two sets of placement components is the pressure zone of the object under test.

[0011] Furthermore, it also includes a support and a hydraulic press, the hydraulic press being mounted above the placement assembly via the support, and the drive end of the hydraulic press being provided with a pressure head assembly that can act on the object to be tested.

[0012] Furthermore, the pressure head assembly includes a fixed pressure head, which is connected to the drive end via a connector.

[0013] Furthermore, a disassembly pressure head is detachably mounted on the outside of the fixed pressure head.

[0014] Furthermore, the pressure-applying surface of the pressure head of the pressure head assembly is an arc surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by adopting a limiting structure, the test object can be stably placed, and the edge of different test objects can be automatically found and limited. This can avoid the test object being squeezed and causing positional displacement after pressure is applied during the test, thereby improving the safety of the pressure bending test.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1 to 9 This utility model provides an engineering testing device, including a placement component 2 for accommodating a test object. The placement component 2 includes a limiting structure for locating and restricting the edge of the test object, and the limiting structure has a resting position for placing the test object. In this embodiment, the limiting structure not only stably places the test object but also automatically locates and restricts the edge of different test objects. This avoids the test object being squeezed and shifting its position when pressure is applied during the testing process, thereby improving safety during the pressure bending test. Specifically, when the test object is placed on the placement component 2, the limiting structure of the placement component 2 automatically locates and restricts the edge of the test object, thus limiting the position of the test object and preventing it from moving during the testing process. This device can be used in any situation requiring pressure testing, such as a laboratory.

[0028] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9The limiting structure includes a base and a plurality of protruding rods 203. Each protruding rod 203 has a limiting ring 205 at one end facing the base. A spring 206 aligned with the length direction of the protruding rod 203 is mounted on the limiting ring 205. The base has a movable groove 202 for inserting the protruding rod 203 and the spring 206. When the spring 206 is compressed into the movable groove 202, the limiting ring 205 is locked in the movable groove 202. In this embodiment, the aforementioned limiting structure is further refined. It can be composed of a base, a protruding rod 203, etc. The bottom of the protruding rod 203 is provided with a limiting ring 205 and a spring 206. When no pressure is applied to the protruding rod 203, the protruding rod 203 can remain outside the movable groove 202 under the action of the spring 206. When pressure is applied to the protruding rod 203, the protruding rod 203 enters the movable groove 202, and the spring 206 is compressed until the limiting ring 205 on the protruding rod 203 abuts against the groove wall of the movable groove 202. The opening of the movable groove 202 can be designed to gradually decrease in size. When the limiting ring 205 slides to a certain point in the movable groove 202, it will be limited by the groove wall of the movable groove 202. Alternatively, it can be designed so that the limiting ring 205 is always sent to the bottom of the movable groove 202 and abutted by the bottom. Both of these methods are specific embodiments of the engagement between the limiting ring 205 and the movable groove 202. Figure 1 The design includes multiple protruding rods 203. The area formed by the interaction of these protruding rods 203 should be larger than the surface of the object under test that will contact the protruding rods 203. Therefore, when the object under test is placed on the protruding rods 203, those protruding rods 203 in contact with the bottom surface of the object will be pressed into the movable groove 202, while the protruding rods 203 that are not pressed down remain outside the movable groove 202. These protruding rods 203 outside the movable groove 202 can then limit the movement of the object under test along its edge. Alternatively, besides the aforementioned limiting structure, a curable soft structure can be used, such as curable adhesive, plaster, or cement. Initially, these materials are soft. When the object under test is placed on these soft structures, its weight creates a depression in the soft structure. Once the soft structure hardens, it can limit the movement of the object under test. Preferably, when using such a soft structure, a protective layer can be placed over the object under test to prevent damage during removal. Preferred, such as Figure 9 As shown, a limiting groove 204 is provided on the side of the protruding rod 203 near the slide block 201. The limiting groove 204 is a blind groove, which allows one end of the spring 206 to extend into it. Thus, part of the spring 206 extends into the limiting groove 204 and the other part extends into the movable groove 202.

[0029] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 Each protruding rod 203 and each movable groove 202 can be arranged in an array, such as the block shape shown in this embodiment.

[0030] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The device also includes a slide rail 3, and the base is a slide block 201. A slide bar 5 is provided on the slide block 201, and the slide bar 5 is slidably disposed on the slide groove 4 of the slide rail 3. In this embodiment, the slide rail 3 and the base being defined as the slide block 201 facilitate adjustment of the position of this limiting structure and make detection easier. Preferably, the slide groove 4 is a dovetail groove, and the slide bar 5 is a dovetail protrusion that engages with the dovetail groove. The use of a dovetail groove and a dovetail protrusion prevents the slide bar 5 from arbitrarily dislodging from the slide groove 4. Preferably, the base is provided with a locking structure that can be locked onto the slide rail 3. After the position is adjusted, the locking structure locks the base onto the slide rail 3, preventing further movement of the base. Preferably, the locking structure can be a fastening bolt 6.

[0031] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The placement component 2 comprises at least two sets, which cooperate to support the object under test, and the area between the two sets of placement components 2 forms the pressure application zone for the object under test. In this embodiment, two sets of placement components 2 are shown, which allows the object under test to be supported, facilitating the application of the pressure head component to the object under test.

[0032] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9The device also includes a support 12 and a hydraulic press 8. The hydraulic press 8 is mounted above the placement assembly 2 via the support 12. The drive end of the hydraulic press 8 is equipped with a pressure head assembly that can act on the object to be tested. In this embodiment, the hydraulic press 8 is used to provide the detection force. By supporting the hydraulic press 8 via the support 12, its pressure head assembly can be easily applied to the object to be tested on the placement assembly 2. Preferably, the pressure head assembly includes a fixed pressure head 9, which is connected to the drive end via a connector 10. A detachable pressure head 11 is detachably mounted on the fixed pressure head 9. Pressure can be applied using the fixed pressure head 9 or the detachable pressure head 11. The detachable nature of the detachable pressure head 11 allows for the selection of different sizes and functions of the detachable pressure head 11 according to different scenarios. Preferably, the pressure surface of the pressure head of the pressure head assembly is an arc surface, which allows for bending detection. Preferably, the output end of the hydraulic press 8 is movably connected through the bracket 12, and the output end of the hydraulic press 8 is fixedly connected to the connector 10. By placing the experimental object on top of the placement component 2, the experimental object overcomes the force of the spring 206 through gravity, causing the protruding rod 203 to move down to the limit position to form a height difference, thereby adapting to the edge contour of the experimental object and completing the limiting of the experimental object. This allows for adaptive limiting of different types of experimental objects such as steel plates and reinforcing bars, thereby improving convenience, applicability, and compatibility.

[0033] As an optimized solution of this utility model embodiment, please refer to Figures 1 to 9 The slide rail 3 is mounted on the operating table 1 via the base 7. The operating table 1 can control the operation of the hydraulic press 8. The base 7 and the aforementioned support bracket 12 can be placed on the table surface of the operating table 1.

[0034] The working process of this device is as follows:

[0035] During use, the experimental object is placed on top of the placement component 2 (i.e., on top of the placement platform formed by the multiple protruding rods 203). When the experimental object is placed on the protruding rods 203, the weight of the experimental object overcomes the force of the spring 206, causing the protruding rods 203 covered by the experimental object to move downwards until the bottom of the limiting ring 205 abuts against the bottom inner wall of the movable groove 202. Because the protruding rods 203 covered by the experimental object move downwards, their height relative to the protruding rods 203 not covered by the experimental object remains unchanged. At this time, a height difference is formed, allowing the experimental object to... The sides are limited and covered by the non-lowered protruding rod 203, which can adaptively limit the experimental objects of different specifications and shapes. After the experimental object is placed, the hydraulic press 8 is started, so that the output end of the hydraulic press 8 extends, and pressure is applied to the experimental object by fixing the pressure head 9 or removing the pressure head 11, thereby performing bending degree detection. The positions of the two slide blocks 201 are adjusted by the slide bar 5 and the slide groove 4, and moved to the appropriate position by the scale bar on one side of the slide rail 3. Then, the positions of the two slide blocks 201 are fixed by the fastening bolt 6 against one side of the slide rail 3.
