Technical Field

[0001] The present invention relates to a steel structure anti-impact detection device, in particular to a steel structure anti-impact detection device applied to the field of steel material detection. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates, and uses silanization, pure manganese phosphating, water washing and drying, galvanizing and other rust removal and rust prevention processes. The components or parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, venues, super high-rise buildings, bridges and other fields.

[0003] Steel structures are mostly used as the main load-bearing parts, and their impact resistance is particularly valued. Therefore, the impact resistance of steel structures will be tested during the production process of steel structures.

[0004] The utility model patent CN212206948U specification discloses a building steel structure detection device, which realizes the detection of impact load and static load of building steel structures of different sizes through an impact load mechanism and a static load mechanism that can slide along the pressure plate. The impact load mechanism can simulate the effect of the impact load, and the static load mechanism can apply a static load to the steel structure to be tested.

[0005] The existing impact resistance testing methods for steel structures are mostly destructive testing, which means that the impact resistance testing of steel structures can usually only be carried out by sampling a number of steel structures in the same batch, making it difficult to achieve large-scale impact resistance testing of steel structures. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the impact resistance test of steel structures can usually only select a number of steel structures of the same batch for sampling test, which makes it difficult to achieve large-scale impact resistance test of steel structures.

[0007] To solve the above problems, the present invention provides a steel structure impact resistance testing device, including a workbench, a workpiece to be tested is placed on the upper end of the workbench, a bracket is fixedly connected to the side wall of the workbench, an impact hydraulic rod is fixedly connected to the side of the bracket away from the connection end with the workbench, and the end of the impact hydraulic rod away from the bracket faces the workbench, the end of the impact hydraulic rod away from the bracket is fixedly connected to a mounting piece, the end of the mounting piece away from the bracket is sleeved with a fixed structure, the lower end of the fixed structure is fixedly connected to an impact bottle, the impact bottle is made of high-strength acrylic material, the inner diameter of the opening at the lower end of the fixed structure is larger than the outer diameter of the lower end of the mounting piece, a compression spring is fixedly connected between the fixed structure and the mounting piece, and the compression spring is sleeved on the outer side of the lower part of the mounting piece.

[0008] In the above-mentioned steel structure impact resistance testing equipment, it can be achieved that all the workpieces to be tested are tested, thereby increasing the coverage of the testing of the workpieces to be tested.

[0009] As a further improvement of the present application, the fixing structure includes a fixer, and an elastic rubber ring is fixedly connected to the connection between the fixer and the impact bottle, and the elastic rubber ring has an interference fit with the impact bottle. The elastic rubber ring is used to fix the impact bottle, which facilitates the installation and removal of the impact bottle.

[0010] As a further improvement of the present application, the impact bottle includes a bottle body, a pre-cut groove is bored in the bottle body, and the pre-cut groove is coaxial with the pre-cut groove, and the upper end of the bottle body is narrow at the top and wide at the bottom. On the one hand, the boring of the pre-cut groove can facilitate the control of the overall structural strength of the impact bottle, and facilitate the manufacture of impact bottles of various required ultimate strengths, which is suitable for various testing needs. On the other hand, the boring of the pre-cut groove can control the fracture position of the overall impact bottle when it is impacted, reduce the number of fragments produced by the fracture of the impact bottle, facilitate subsequent cleaning work, and ensure that the residual part of the impact bottle connected to the fixed structure after the fracture is long enough to push the fixed structure to a position where it can fall off automatically.

[0011] As a further improvement of the present application, a pair of guide plates are fixedly connected to the workbench, and the two guide plates are respectively located on both sides of the impact hydraulic rod, so as to make certain fine adjustments to the feeding direction of the workpiece to be inspected, thereby positioning the workpiece to be inspected.

[0012] As another improvement of the present application, a protective cover is provided on the lower side of the fixed structure, a connecting bracket is fixedly connected between the protective cover and the two guide plates, the protective cover includes an upper cover body, and a collection column is fixedly connected to the lower end of the upper cover body, which can effectively prevent the debris generated by the breakage of the impact bottle from splashing.

[0013] As another improvement supplement of the present application, a plurality of sealing strips are fixedly connected to the opening at the upper end of the upper cover body, and the plurality of sealing strips are all made of elastic material to increase the overall sealing effect of the protective cover and prevent the splashing of debris generated by the breakage of the impact bottle.

[0014] As another improved supplement of the present application, the collecting column includes a collector body, a partition is fixedly connected to the lower end of the collector body, and the direction in which the workpiece to be inspected moves out of the inspection position passes through the notch of the partition, and a collecting chamber is formed between the collector body and the partition. The collector body has an inclined groove at the opening of the partition. When the workpiece to be inspected moves out of the workstation, it will drive the impact bottle fragments to move together, and under the action of the collector body, the above-mentioned impact bottle fragments are collected in the collecting chamber.

[0015] As another improvement supplement of the present application, a plurality of fixing units are fixedly connected in the collection chamber, and the plurality of fixing units are interlaced to form a three-dimensional structure, so as to fix the fragments of the impact bottle to a certain extent, so that the fragments of the impact bottle are not easy to scatter.

[0016] As another improvement of the present application, the impact bottle is filled with fluorescent marking liquid, and the fluorescent marking liquid is of a type that is easy to dry and solidify, so that the workpiece to be inspected after the impact test can be marked. At the same time, the impact generated when the impact bottle explodes will drive the fluorescent marking liquid to form radial marks, which can easily distinguish manually applied marks.

[0017] In summary, in the present application, an impact hydraulic rod is used to drive an impact bottle to hit the bracket to realize the impact strength test of the bracket, wherein the ultimate strength of the impact bottle is the detection strength required by the workpiece to be tested. Therefore, during the detection process, once the impact received by the impact hydraulic rod during the detection process reaches the preset detection strength, the impact bottle will rupture, and the impact pressure received by the workpiece to be tested will be reduced instantly, and the damage that may be caused to the workpiece to be tested during the impact detection process will be transferred to the impact bottle, and the purpose of the impact detection will also be achieved, so that the workpiece to be tested can be inspected as much as possible and the detection coverage of the workpiece to be tested can be increased.

[0018] At the same time, a protective cover is used to protect the impact detection, which effectively prevents the debris generated by the breakage of the impact bottle from splashing, and when the workpiece to be detected is moved out of the workstation, the fragments of the impact bottle will be driven to move together, and under the action of the collector body, the fragments of the impact bottle are collected in the collection chamber, and the workpiece to be detected that has passed the impact test can be marked with a fluorescent marking liquid. At the same time, the impact generated when the impact bottle explodes will drive the fluorescent marking liquid to form radial marks, which is easy to distinguish the manually applied marks.

DETAILED DESCRIPTION

[0031] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-3 A steel structure impact resistance testing device is shown, including a workbench 1, a workpiece 2 to be tested is placed on the upper end of the workbench 1, a bracket 3 is fixedly connected to the side wall of the workbench 1, an impact hydraulic rod 4 is fixedly connected to the side of the bracket 3 away from the connection end with the workbench 1, and the end of the impact hydraulic rod 4 away from the bracket 3 faces the workbench 1, and the end of the impact hydraulic rod 4 away from the bracket 3 is fixedly connected to a mounting member 5 away from the bracket 3. The end of the mounting member 5 away from the impact hydraulic rod 4 is sleeved with a fixed structure 6, and the lower end of the fixed structure 6 is fixedly connected to an impact bottle 7, which is made of high-strength acrylic material. The inner diameter of the opening at the lower end of the fixed structure 6 is larger than the outer diameter of the lower end of the mounting member 5. A compression spring 8 is fixedly connected between the fixed structure 6 and the mounting member 5, and the compression spring 8 is sleeved on the outer side of the lower part of the mounting member 5.

[0034] In this scheme, the workbench 1 can be transported to the lower side of the impact hydraulic rod 4 by a transmission belt or a mechanical arm, and then the impact hydraulic rod 4 is accelerated according to the preset impact strength, and the impact bottle 7 is smashed against the bracket 3 to implement the impact strength test of the bracket 3, wherein the ultimate strength of the impact bottle 7 is the detection strength required by the workpiece 2 to be detected. Therefore, during the detection process, once the impact of the impact hydraulic rod 4 during the detection process reaches the preset detection strength, the impact bottle 7 will rupture, and the impact pressure on the workpiece 2 to be detected will be instantly reduced, and the damage that may be caused to the workpiece 2 to be detected during the impact detection process will be transferred to the impact bottle 7, and the purpose of the impact detection can also be achieved, and the detection coverage of the workpiece 2 to be detected can be increased.

[0035] See also Figure 3 The fixing structure 6 includes a fixing device 601, and an elastic rubber ring 602 is fixedly connected to the connection between the fixing device 601 and the impact bottle 7, and the elastic rubber ring 602 is interference fit with the impact bottle 7. The impact bottle 7 is fixed by the elastic rubber ring 602, which is convenient for installation and removal of the impact bottle 7. The impact bottle 7 includes a bottle body 701, and a pre-cut groove 702 is cut in the bottle body 701, and the pre-cut groove 702 is coaxial with the pre-cut groove 702, and the upper end of the bottle body 701 is narrow at the top and wide at the bottom. On the one hand, the cutting of the pre-cut groove 702 can facilitate the control of the overall structural strength of the impact bottle 7, and facilitate the manufacture of the impact bottle 7 with the required ultimate strength, which is suitable for various detection requirements. On the other hand, the cutting of the pre-cut groove 702 can control the fracture position of the impact bottle 7 as a whole when it is impacted, reduce the number of fragments generated by the fracture of the impact bottle 7, and facilitate subsequent cleaning work. In addition, it is ensured that the residual part of the impact bottle 7 connected to the fixing structure 6 after the fracture is long enough to push the fixing structure 6 to a position where it can automatically fall off.

[0036] See also Figure 5 When the impact bottle 7 collides with the workpiece 2 to be detected, the impact bottle 7 will push the fixed structure 6 to move upward until the upper end of the impact bottle 7 contacts the lower end of the mounting member 5. The impact on the impact bottle 7 instantly rises, and the impact bottle 7 breaks along the direction of the pre-cut groove 702. At the same time, the impact bottle 7 also breaks away from the fixation of the fixed structure 6, completing the automatic falling-off work.

[0037] The second implementation method:

[0038] Figure 6-10 A steel structure impact resistance testing device is shown, including a pair of guide plates 9 fixedly connected to a workbench 1. The two guide plates 9 are respectively located on both sides of an impact hydraulic rod 4, and can perform certain fine adjustments on the feeding direction of the workpiece 2 to be tested, thereby positioning the workpiece 2 to be tested.

[0039] A protective cover is provided on the lower side of the fixed structure 6, and a connecting bracket 10 is fixedly connected between the protective cover and the two guide plates 9. The protective cover includes an upper cover body 11, and a collecting bar 13 is fixedly connected to the lower end of the upper cover body 11, which can effectively prevent the debris generated by the break of the impact bottle 7 from splashing. A plurality of sealing strips 12 are fixedly connected to the opening of the upper end of the upper cover body 11, and the plurality of sealing strips 12 are made of elastic material to increase the overall sealing effect of the protective cover and prevent the debris generated by the break of the impact bottle 7 from splashing. The collecting bar 13 includes a collector body 1301, and a partition 1302 is fixedly connected to the lower end of the collector body 1301, and the workpiece 2 to be detected A collecting chamber is formed between the collector body 1301 and the partition 1302 through the notch of the partition 1302 in the direction of moving out from the detection position. The collector body 1301 is provided with an inclined groove 1303 at the opening of the partition 1302. When the workpiece 2 to be detected is moved out from the work station, the fragments of the impact bottle 7 will be driven to move together, and under the action of the collector body 1301, the fragments of the impact bottle 7 are collected into the collecting chamber. A plurality of fixing units 1304 are fixedly connected in the collecting chamber, and the plurality of fixing units 1304 are staggered to form a three-dimensional structure, which is convenient for fixing the fragments of the impact bottle 7 to a certain extent, so that the fragments of the impact bottle 7 are not easy to scatter.

[0040] The impact bottle 7 is filled with fluorescent marking liquid, and the fluorescent marking liquid is of a type that is easy to dry and solidify. It can mark the workpiece 2 to be tested after the impact test. At the same time, the impact generated when the impact bottle 7 explodes will drive the fluorescent marking liquid to form radial marks, which is easy to distinguish manually applied marks.

[0041] Compared with the first embodiment, in this embodiment, a protective cover is used to protect the impact detection, which effectively prevents the debris generated by the breakage of the impact bottle 7 from splashing, and when the workpiece 2 to be detected is moved out of the workstation, it will drive the fragments of the impact bottle 7 to move together, and under the action of the collector body 1301, the fragments of the impact bottle 7 are collected in the collection chamber, and the workpiece 2 to be detected that has passed the impact test can be marked. At the same time, the impact generated when the impact bottle 7 explodes will drive the fluorescent marking liquid to form radial marks, which is easy to distinguish the manually applied marks.

[0042] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
