Description

Technical Field

[0001] This utility model relates to the field of steel testing, specifically a device for testing the bending toughness of building steel. Background Technology

[0002] Construction steel plays a crucial role in engineering projects, including load-bearing, shear resistance, and earthquake resistance. Its bending toughness is a key indicator for measuring mechanical properties and safety reliability. To ensure the quality of construction steel, it is necessary to conduct professional testing using bending toughness testing equipment.

[0003] In existing technologies, the operation process of some building steel bending toughness testing devices is as follows: the steel is placed on the support frame of the device, the hydraulic device is activated to drive the bending block, and the bending toughness is tested by applying a compressive force to the surface of the steel. In order to reduce the possible injury to workers caused by steel cracking during the testing process, such devices are usually equipped with protective shells.

[0004] However, in practice, it has been found that the opening and closing doors of some protective shells adopt a single-leaf hinge design. This structure requires a large amount of horizontal and vertical space when opening and closing. If there are other devices around the testing area, spatial interference is likely to occur, resulting in inconvenience in operation and poor practicality. Therefore, in order to address the above problems, a bending toughness testing device for building steel is proposed. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a device for testing the bending toughness of building steel.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: a bending toughness testing device for building steel includes a supporting shell, a supporting frame fixedly connected to the top of the supporting shell, a bending press arranged in the middle of the supporting frame, a supporting platform located in the middle of the supporting frame at the top of the supporting shell, a through groove 1 in the middle of the supporting frame, a through groove 2 in the middle of the supporting shell, the through groove 1 and the through groove 2 being connected, a protective plate slidably attached to the middle of the supporting frame, the outer wall of the protective plate slidably attached to the middle of the supporting shell, a transparent protective plate fixedly connected to the middle of the protective plate, a rectangular plate slidably attached to the middle of the transparent protective plate, the outer wall of the rectangular plate simultaneously sliding in the middle of the through groove 1 and the through groove 2, a limiting groove is formed on the side wall at the bottom of the rectangular plate, a limiting rod is slidably connected through the side wall of the supporting frame, the limiting rod is inserted into the middle of the limiting groove, and a handle is fixedly attached to the side wall at the top of the protective plate.

[0007] Preferably, a second protective plate is slidably connected to the middle of the support frame, an L-shaped plate is fixed to the top side wall of the second protective plate, a rectangular strip is fixed to the bottom side wall of the L-shaped plate, a groove is provided on the side wall of the support frame, a slider is elastically connected to the middle of the groove by a spring, the outer wall of the slider is slidably connected to the middle of the groove, one end of the spring is fixed to the middle of the groove, and the other end of the spring is fixed to the top of the slider.

[0008] Preferably, a pin is slidably connected to the middle of the rectangular strip, the outer wall of the end of the pin is slidably connected to the middle of the slider, a groove is provided in the middle of the slide groove, the pin is inserted into the middle of the groove, and a rolling column is rotatably connected to the inner wall of the bottom of the second protective plate.

[0009] Preferably, a connecting plate is fixedly connected to the end of the limiting rod, and a second spring is sleeved on the outer wall of the limiting rod. One end of the second spring is fixedly connected to the side wall of the end of the connecting plate, and the other end of the second spring is fixedly connected to the side wall of the support frame.

[0010] Preferably, a damping telescopic rod is fixedly connected to the side wall of the rectangular plate, and the other end of the damping telescopic rod is fixedly connected to the middle of the protective plate.

[0011] Preferably, there are two sets of the second protective plate and the L-shaped plate, and the two sets of the second protective plate and the L-shaped plate are symmetrically arranged with the center line of the support frame as the axis of symmetry. The other end of the rectangular strip is fixed to the side wall at the bottom of the multiple sets of L-shaped plates.

[0012] Preferably, the end of the limiting rod is configured as an inclined surface.

[0013] The advantages of this utility model are as follows: through the cooperation between the protective plate 1, the connecting plate, the rectangular plate, the limiting rod and the spring 2, it is ensured that the protective plate 1 can be retracted into the middle of the support shell after opening, reducing the risk of spatial interference and inconvenience in operation. The damping rod can buffer the impact force on the protective plate 1 and ensure its service life. In addition, through the cooperation between the L-shaped plate, the rectangular bar, the pin, the slider and the spring 1, the height of the protective plate 2 can be adjusted to ensure that even excessively long steel can be placed in the middle of the support frame for inspection.

[0014] This invention uses a feeding plate to disengage the locking block from the center of the L-shaped sliding plate. At this point, the closed automatic reciprocating telescopic rod falls due to gravity and enters the center of the feeding rack, reducing its space-consuming risk. To close, simply pull the automatic reciprocating telescopic rod. When fully closed, the locking block inserts into the center of the L-shaped sliding plate, limiting its movement and effectively concealing the automatic reciprocating telescopic rod, thus reducing its space-consuming nature when open. This solves the problem of some devices where the opening and closing doors occupy significant horizontal and vertical space, and where spatial interference can easily occur if other equipment is present around the detection area, leading to inconvenience and poor practicality.

[0022] 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 protection scope of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0024] This application discloses a device for testing the bending toughness of building steel. (Refer to...) Figure 1 - Figure 2 and Figure 5A bending toughness testing device for building steel includes a supporting shell 1, a supporting frame 2 fixedly connected to the top of the supporting shell 1, a bending press 21 disposed in the middle of the supporting frame 2, a supporting platform 22 disposed at the top of the supporting shell 1 and in the middle of the supporting frame 2, a through groove 23 23 24 24 24 24 24 35 36 37 38 39 ... The protective plate 3 has a transparent protective plate 4 fixedly connected to its middle section. A rectangular plate 10 is slidably connected to the middle section of the transparent protective plate 4. The outer wall of the rectangular plate 10 slides simultaneously in the middle of the through groove 23 and the through groove 24. A limiting groove 18 is formed on the side wall of the bottom of the rectangular plate 10. A limiting rod 19 is slidably connected through the side wall of the support frame 2. The limiting rod 19 is inserted into the middle of the limiting groove 18. A handle 6 is fixedly connected to the side wall of the top of the protective plate 3. During operation, when it is necessary to open the protective plate 3, steel is placed to be fed through the bending press 21. During the bending toughness test, the limiting rod 19 can be pulled until it is completely disengaged from the middle of the limiting groove 18. At this time, the protective plate 3 will fall due to gravity and will enter the middle of the supporting shell 1 from the middle of the supporting frame 2. During this process, the protective plate 3 will drive the rectangular plate 10 to move. The rectangular plate 10 will slide from the middle of the through groove 23 into the middle of the through groove 24 until the handle 6 contacts the top of the supporting shell 1. The protective plate 3 will then stop falling. When closing, you can hold the handle 6 and pull the protective plate 3. When the protective plate 3 moves upward, it will cause the rectangular plate 10 to slide from the middle of the through groove 24 to the middle of the through groove 23 until the protective plate 3 is completely closed. The limiting rod 19 will coincide with the limiting groove 18 and be inserted into the middle of the limiting groove 18 to limit the rectangular plate 10. Through the above operation, the risk of spatial interference of the protective plate 3 and inconvenience in operation can be reduced. It should be noted that the handle 6 is located inside the connecting plate 5 to ensure that when closed, the handle 6 can pass smoothly through the connecting plate 5 to make the protective plate 3 fully open.

[0025] Reference Figure 1 and Figure 3A protective plate 7 is slidably connected to the middle of the support frame 2. An L-shaped plate 8 is fixed to the top side wall of the protective plate 7, and a rectangular strip 12 is fixed to the bottom side wall of the L-shaped plate 8. A groove 16 is provided on the side wall of the support frame 2. A slider 14 is elastically connected to the middle of the groove 16 by a spring 15. The outer wall of the slider 14 is slidably connected to the middle of the groove 16. One end of the spring 15 is fixed to the middle of the groove 16, and the other end of the spring 15 is fixed to the top of the slider 14. During operation, the protective plate 7 can protect the other side of the support frame 2. When the steel to be inspected is too long, the protective plate 7 can be... 7. Open the frame to ensure the steel can be placed smoothly in the middle of the support frame 2. When opening, simply push the rectangular bar 12. The rectangular bar 12 will move the L-shaped plate 8, which will move the protective plate 7. At the same time, the rectangular bar 12 will move the slider 14 in the slide groove 16 and squeeze the spring 15. At this time, the steel can be placed in the middle of the support frame 2. After placement, the protective plate 7 can be reset. The protective plate 7 will contact the top of the steel through the elasticity of the spring 15 to ensure the maximum protection effect. When the steel is being inspected, the protective plate 7 will move according to the bending degree, which improves practicality.

[0026] Reference Figure 3 A pin 13 is slidably connected to the middle of the rectangular strip 12. The outer wall of the end of the pin 13 is slidably connected to the middle of the slider 14. A groove 11 is provided in the middle of the slide groove 16. The pin 13 is inserted into the middle of the groove 11. A rolling column 9 is rotatably connected to the inner wall of the bottom of the second protective plate 7. When the second protective plate 7 is opened during operation, the pin 13 can be inserted into the middle of the groove 11 to ensure that it remains in the open state. In this way, when placing steel, it is not necessary to continuously push the rectangular strip 12 to keep the second protective plate 7 in the open state, which improves convenience.

[0027] Reference Figure 2 and Figure 5 The limiting rod 19 is fixedly connected to a connecting plate 5 at its end. A second spring 20 is sleeved on the outer wall of the limiting rod 19. One end of the second spring 20 is fixedly connected to the side wall of the connecting plate 5, and the other end of the second spring 20 is fixedly connected to the side wall of the support frame 2. During operation, there are two sets of limiting rods 19, and the two sets of limiting rods 19 are connected by the connecting plate 5. By pulling the connecting plate 5, multiple sets of limiting rods 19 can be moved synchronously. The second spring 20 itself has a certain elasticity, which can improve the stability of the limiting rod 19 when inserted into the limiting groove 18.

[0028] Reference Figure 4The rectangular plate 10 has a damping telescopic rod 17 fixed to its side wall. The other end of the damping telescopic rod 17 is fixed to the middle of the protective plate 3. During operation, the damping telescopic rod 17 will buffer the impact force on the protective plate 3, reduce hard contact, and prevent damage to the protective plate 3. The damping telescopic rod 17 is existing technology and can be implemented by those skilled in the art. Since it is existing technology, it will not be described in detail in this case.

[0029] Reference Figure 2 The protective plate 7 and L-shaped plate 8 are provided in two sets, and the two sets of protective plates 7 and L-shaped plates 8 are symmetrically arranged with the center line of the support frame 2 as the axis of symmetry. The other end of the rectangular strip 12 is fixed to the side wall at the bottom of the multiple sets of L-shaped plates 8. When working, the two sets of protective plates 7 and L-shaped plates 8 can protect both sides of the support frame 2, and the two sets of protective plates 7 and L-shaped plates 8 are connected by the rectangular strip 12 to ensure that they can be opened easily.

[0030] Reference Figure 5 The end of the limiting rod 19 is set with an inclined surface. During operation, the inclined surface ensures that when the protective plate 3 is closed, the rectangular plate 10 can be pushed along the inclined surface of the limiting rod 19 to move without manual pulling, which improves convenience.

[0031] Working principle: When it is necessary to open the protective plate 3 and place the steel to bend through the bending press 21 for bending toughness testing, the limiting rod 19 can be pulled until it is completely disengaged from the middle of the limiting groove 18. At this time, the protective plate 3 will fall under gravity and enter the middle of the supporting shell 1 from the middle of the supporting frame 2. During this process, the protective plate 3 will drive the rectangular plate 10 to move. The rectangular plate 10 will slide from the middle of the through groove 23 into the middle of the through groove 24 until the handle 6 contacts the top of the supporting shell 1. The protective plate 3 will then stop falling. When closing, hold the handle 6 and pull the protective plate 3 upward. The protective plate 10 will drive the rectangular plate 10 to move upward. 10 slides from the middle of the second through slot 24 to the middle of the first through slot 23. The rectangular plate 10 will move along the inclined surface of the limiting rod 19. The limiting rod 19 will drive the connecting plate 5 to move. The connecting plate 5 will stretch the second spring 20 until the first protective plate 3 is completely closed. The limiting rod 19 will coincide with the limiting groove 18. The second spring 20 will drive the limiting rod 19 to insert into the middle of the limiting groove 18 through its own elasticity, thus limiting the rectangular plate 10. Through the above operation, the risk of spatial interference of the first protective plate 3, which may lead to inconvenience in operation, can be reduced. It should be noted that the handle 6 is located inside the connecting plate 5 to ensure that when closed, the handle 6 can pass smoothly through the connecting plate 5, so that the first protective plate 3 can be fully opened.

[0032] The protective plate 2 7 can protect the other side of the support frame 2. When the steel to be tested is too long, the protective plate 2 7 can be opened to ensure that the steel can be placed smoothly in the middle of the support frame 2. When opening, simply hold the pin 13 and push the rectangular bar 12. The rectangular bar 12 will drive the L-shaped plate 8 to move, and the L-shaped plate 8 will move the protective plate 2 7. At the same time, the rectangular bar 12 will drive the slider 14 to move in the slide groove 16 and squeeze the spring 15 until the pin 13 coincides with the groove 11. Insert the pin 13 into the middle of the groove 11. At this time, the steel can be placed in the middle of the support frame 2. After placement, the protective plate 2 7 can be reset. The protective plate 2 7 will contact the top of the steel through the elasticity of the spring 15 to ensure the maximum protection effect. When the steel is being tested, the protective plate 2 7 will move accordingly, improving practicality.
