Description

Technical Field

[0001] This utility model relates to the field of bar flaw detection technology, specifically to a receiving device for a bar flaw detector and a bar flaw detector. Background Technology

[0002] After steel production is completed, a flaw detector is needed for inspection. A flaw detector is a device used to detect internal and surface defects in steel. It belongs to a type of non-destructive testing technology and is mainly used to check the quality and safety of steel. By utilizing physical properties, the flaw detector can detect various defects inside or on the surface of the material, such as cracks, pores, and inclusions, without impairing the performance of the steel. This technology is crucial for ensuring the quality and safety of steel and is an indispensable testing tool in industrial production.

[0003] Currently, most flaw detectors use feeding devices that consist of a frame and a turning device. Multiple conveyor wheel mechanisms are installed along the length of the frame. These conveyor mechanisms transport the bar stock along the frame's length. When the bar stock reaches the feeding area, the conveyor wheel mechanisms stop, and then the turning device flips the bar stock on the frame and feeds it into the feeding area. For example, Chinese utility model patent application number "201220628969.X" uses this method to feed bar stock.

[0004] However, since the height of the frame is usually at least 1 meter above the ground, when the bar is flipped and unloaded, it will generate a large impact and abnormal noise when it is thrown into the unloading area. Moreover, when workers take the bar away, they are also easily injured by the bar with a large impact force. Utility Model Content

[0005] (I) The problem to be solved by this utility model is that the height of the frame is usually at least 1 meter from the ground. When the bar is flipped and unloaded, it will generate a large impact and abnormal noise. Moreover, when workers take away the bar, they are also easily injured by the bar with a large impact force.

[0008] The upright is set vertically, the top rod is a diagonal rod, the first end of the top rod is connected to the upright, and the second end of the top rod points towards the frame. From the first end to the second end of the top rod, the height of the top rod gradually decreases, and the top surface of the top rod is not lower than the top surface of the upright.

[0009] The lifting block can be slidably installed on the upright along the height direction of the upright, and the elastic element is disposed below the lifting block to relieve the downward impact force of the lifting block;

[0010] The contact plate is vertically mounted on the lifting block, and the top of the contact plate is higher than the top rod. A receiving space for receiving rods is formed between the upright rod, the lifting block, and the contact plate.

[0011] According to one embodiment of the present invention, an angle is formed between the upper surface of the top rod and the upper surface of the upright rod, and the angle is an obtuse angle.

[0014] According to one embodiment of the present invention, the contact plate is a flexible metal plate.

[0015] According to one embodiment of the present invention, it further includes at least one support member for supporting the contact plate to prevent the contact plate from tilting excessively. The support member includes a one-to-one corresponding support plate and an extension rod. The extension rod is disposed on the end face of the lifting block and is perpendicular to the contact plate. The support plate is a metal elastic plate. One end of the support plate is connected to the end of the extension rod away from the lifting block, and the other end of the support plate abuts against the contact plate.

[0019] A bar flaw detector includes the aforementioned receiving device for a bar flaw detector.

[0020] The beneficial effects of this utility model are:

[0021] This utility model provides a receiving device for a bar flaw detector, which is installed on one side of the frame of the bar flaw detector's unloading device for receiving bars. It includes a vertical pole, a top rod, a lifting block, at least one elastic element, and at least one contact plate. The vertical pole is vertically arranged, the top rod is an inclined rod, with its first end connected to the vertical pole and its second end pointing towards the frame. From the first end to the second end, the height of the top rod gradually decreases, and the top surface of the top rod is not lower than the top surface of the vertical pole. The lifting block is slidably installed on the vertical pole along its height direction.

A receiving space for receiving bars is formed between the vertical pole, the lifting block, and the contact plate.

[0022] The actual falling height of the bar is small, thus reducing its kinetic energy during the fall and greatly reducing the impact force. The bar rolls along the top rod and is stopped by the upper part of the contact plate, further offsetting the impact force. After the bar falls into the receiving space, the elastic potential energy of the elastic element itself is used to offset the final kinetic energy of the bar. The noise level caused during the entire feeding process is reduced, preventing workers from being accidentally injured by the bar, and effectively protecting the bar from surface damage caused by violent collisions.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1:

[0029] like Figures 1-2 As shown, one embodiment of this utility model provides a receiving device for a bar flaw detector, which is set on one side of the frame of the unloading device of the bar flaw detector and is used to receive bars. It includes a vertical rod 2, a top rod 3, a lifting block 6, at least one elastic element and at least one contact plate 7.

[0030] The upright 2 is set vertically, and the top rod 3 is a diagonal rod. The first end of the top rod 3 is connected to the upright 2, and its second end points towards the frame. From the first end to the second end of the top rod 3, the height of the top rod 3 gradually decreases, and the top surface of the top rod 3 is not lower than the top surface of the upright 2.

[0031] The lifting block 6 can be slidably installed on the upright 2 along the height direction of the upright 2. The elastic element is set below the lifting block 6 to relieve the downward impact force of the lifting block 6.

[0032] The contact plate 7 is vertically mounted on the lifting block 6, and the top of the contact plate 7 is higher than the top rod 3. A receiving space for receiving rods is formed between the upright rod 2, the lifting block 6 and the contact plate 7.

[0033] This receiving device is installed in the bar stock stacking area of ​​the flaw detector system, and is located on the side of the bar stock stacking device. It is used to receive the bars stock that have been turned and flipped by the agitator in the bar stock stacking device. Specifically, according to... Figure 1 As shown, install this receiving device in the unloading area so that the top rod 3 is close to the side of the frame in the unloading device.

[0034] The bar, propelled by the actuating device in the feeding device, is thrown onto the upper surface of the push rod 3. As the height of the push rod 3 gradually decreases from one end near the frame to the other, the bar rolls along the push rod 3 and is then stopped by the upper part of the contact plate 7. The bar impacts the contact plate 7, and most of the impact force is offset by the contact plate 7. Then the bar falls into the receiving space and acts on the lifting block 6. As the weight of the lifting block 6 increases, it compresses the elastic element, which offsets the last kinetic energy of the bar.

[0035] In this embodiment, the bar is thrown from the frame onto the push rod 3 by the actuating device. Because the height difference between the first end of the push rod 3 and the frame is small, the actual falling height of the bar is small, thus reducing its kinetic energy during the fall and significantly reducing the impact force. The bar rolls along the push rod 3 and is stopped by the upper part of the contact plate 7, further offsetting the impact force. After the bar falls into the receiving space, the elastic potential energy of the elastic element itself offsets the final kinetic energy of the bar. The noise level during the entire unloading process is reduced, and there is no risk of workers being accidentally injured by the bar.

[0036] As a specific example, such as Figure 1 As shown, the receiving device includes a base plate 1, which is fixedly installed on a bearing base plate laid flat on the ground of the unloading area. A vertical pole 2 is vertically installed on the base plate 1. One end of a top rod 3 is connected to the side of the vertical pole 2 facing the frame, and the other end is close to the side of the frame. The highest point of the top rod 3 is slightly lower than the actuating device on the frame. This reduces the height difference between the rod and the top rod 3, significantly decreasing the impact force on the rod and thus reducing the impact force and noise generated when the rod strikes the contact plate 7.

[0037] Furthermore, such as Figure 1 As shown, an angle is formed between the upper surface of the top rod 3 and the upper surface of the upright rod 2, and the angle is obtuse. Since the end of the top rod 3 that is closer to the frame is higher than the other end, and the top of the contact plate 7 is higher than the upper surface of the upright rod 2, the rod can roll down the upper surface of the top rod 3 to the upper surface of the upright rod 2 and be blocked by the contact plate 7.

[0038] In a preferred embodiment, the contact plate 7 is a metal elastic plate, such as a stainless steel plate or a copper plate. After the rod is blocked by the contact plate 7, the contact plate 7 itself has elasticity, which plays a certain role in buffering. The elasticity of the contact plate 7 itself offsets the impact force of the rod, allowing the rod to stabilize quickly, and it also helps to reduce noise.

[0039] In addition, it should be noted that the bar that falls into the receiving space will eventually fall onto the upper surface of the lifting block 6. Under the gravity of the bar, the lifting block 6 moves downward. Due to the presence of the elastic element, the elastic element is slowly compressed. The elastic element plays a buffering role, offsetting the impact force generated when the bar falls, so that the lifting block 6 can move downward slowly.

[0040] As a specific embodiment, such as Figure 1 and Figure 2As shown, a long, narrow sliding hole 201 extending along the height of the upright 2 is provided on its side. The sliding hole 201 divides the lower half of the upright 2 into two parts, thus the upright 2 can be seen as a U-shaped rod. A vertically arranged round rod 5 is provided between the upper surface of the base plate 1 and the inner top wall of the sliding hole 201. The elastic element is a spring 4, which is sleeved on the outside of the round rod 5. Further, as... Figure 2 As shown, the upper surface of the lifting block 6 has a rectangular insertion hole 601 and a through hole 602 for the round rod 5 to pass through.

[0041] To facilitate the installation and subsequent disassembly of the receiving device, preferably, the bottom side of the round rod 5 has external threads, and a threaded hole is provided on the upper surface of the base plate 1. Bolt holes are provided on both sides of the lower surface of the upright rod 2, and countersunk holes corresponding to the bolt holes on the lower surface of the upright rod 2 are provided on the base plate 1. When assembling this receiving device, first screw the round rod 5 into the threaded hole on the upper surface of the base plate 1. Then, insert one side of the bottom of the upright rod 2 into the insertion hole 601 of the lifting block 6, so that the lifting block 6 is slidably assembled onto the upright rod 2. Push the lifting block 6 in the height direction of the upright rod 2 so that the upper surface of the lifting block 6 is in contact with the inner top wall of the sliding hole 201. Then, put the spring 4 on the outside of the round rod 5. Next, place the upright rod 2 and the lifting block 6 above the base plate 1 and ensure that the through hole 602 on the lifting block 6 is aligned with the round rod 5. Then, slowly move the upright rod 2 and the lifting block 6 down so that the round rod 5 passes through the through hole 602 on the lifting block 6 until the lower surface of the upright rod 2 is in contact with the upper surface of the base plate 1 and the bolt hole on the lower surface of the upright rod 2 is aligned with the countersunk hole on the base plate 1. Finally, use countersunk bolts to fix the upright rod 2 and the base plate 1 together.

[0042] In a preferred embodiment, to prevent excessive impact force from the bar causing the contact plate 7 to tilt excessively and the bar to overshoot the contact plate 7, two support members are installed on the lifting block 6. Each support member includes a corresponding support plate 9 and an extension rod 8. The extension rod 8 is located on the end face of the lifting block 6 away from the top rod 3 and is perpendicular to the contact plate 7. One end of the support plate 9 is connected to the end of the extension rod 8 away from the lifting block 6, and the other end abuts against the contact plate 7. The included angle between the support plate 9 and the extension rod 8 is an acute angle. The two support members are arranged along the width direction of the lifting block 6.

[0043] Preferably, the support plate 9 is a metal elastic plate.

[0044] When the contact plate 7 is impacted by the bar, it bends outward. Since the support plate 9 always supports the contact plate 7, the impact force that the contact plate 7 can withstand is greatly increased. The contact plate 7 will not tilt excessively outward, so as to ensure that the bending degree of the contact plate 7 is within the specified range. This ensures that the contact plate 7 can completely block the bar, preventing the bar from crossing the contact plate 7 and falling into the unloading area, thus improving the safety during material receiving.

[0045] It should be noted that a cylinder is connected to one end of the support plate 9 and the outer side of the contact plate 7, and the cylinder slides in contact with the outer side of the contact plate 7.

[0046] As an optional embodiment, to improve the impact resistance of the contact plate 7, multiple contact plates 7 can be provided, and multiple contact plates 7 are arranged sequentially on the lifting block 6 along the length direction of the top rod 3.

[0047] Considering that when the bars in the receiving space cannot be removed in time, resulting in a large accumulation of bars, the combined weight of the lifting block 6 and the bars in the receiving space exceeds the load that spring 4 can bear. When spring 4 bears a load exceeding its design capacity, it may cause permanent deformation or breakage. To avoid such problems, preferably, as follows... Figure 1 and Figure 2 As shown, an auxiliary block 10 is inserted between the two extension rods 8. The auxiliary block 10 has an I-shaped cross-section, and its two sides are respectively provided with slots that are adapted to the extension rods 8. The auxiliary block 10 is a rubber block, and the lower surface of the auxiliary block 10 is lower than the lifting block 6. When the lifting block 6 falls, the auxiliary block 10 contacts the base plate 1 before the lifting block 6.

[0048] When the combined weight of the lifting block 6 and the bar material in the receiving space exceeds the load that the spring 4 can bear, the lifting block 6 will move the auxiliary block 10 downwards together, and the spring 4 will be gradually compressed. Before the spring 4 is compressed to its limit, the auxiliary block 10 will already be in contact with the base plate 1. At this time, most of the force will be applied to the auxiliary block 10 to ensure that the force borne by the spring 4 will not exceed its load, thereby ensuring that the spring 4 will not undergo permanent deformation or breakage and improving its service life.

[0049] Furthermore, the use of spring 4 and auxiliary block 10 for double buffering greatly improves the load-bearing capacity of this receiving device, enabling it to support more bars.

[0050] It should be noted that the length of the auxiliary block 10 can be reasonably set according to the actual situation. For example, when the depth of the receiving space is large and the number of bars that can be accommodated is large, the length of the auxiliary block 10 can be appropriately increased, and vice versa.

[0051] In this embodiment, the rod, after being actuated by the actuating device, is thrown onto the upper surface of the push rod 3. Since the push rod 3 is slightly lower than the actuating device, the falling height of the rod is limited, resulting in limited impact force. As the height of the push rod 3 gradually decreases from one end near the frame to the other, the rod rolls along the push rod 3 and is then stopped by the upper part of the contact plate 7, striking the contact plate 7. Because the impact force of the rod is limited, and most of the impact force is offset by the contact plate 7, the sound generated by the collision between the rod and the contact plate 7 is low in decibels.

[0052] Then the bar falls into the receiving space and acts on the lifting block 6. The spring 4 is gradually compressed, which plays a good buffering role to offset the force generated by the bar falling and hitting the lifting block 6, eliminate the impact force of the bar falling, avoid large abnormal noise and collision, and ensure that the lifting block 6 can move down slowly.

The bar flaw detector includes a feeding device, which includes a frame, a conveying wheel system and a turning device.
