Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mechanical boom detection, and in particular to a detection frame. Background Art
[0002] The crane arm of construction machinery is mainly responsible for lifting and transporting objects and is an indispensable and important equipment in engineering construction.
[0003] During the manufacturing process of construction machinery booms, four boom parts made of high-strength steel are usually welded together into a complete boom. The four boom parts are all long strips. During the processing of the above-mentioned long strip boom parts, the straightness of the boom parts needs to be tested. The existing detection method mainly uses manual wire pulling detection. The operator uses a fully tightened steel wire as a reference straight line, and determines the straightness error by measuring the deviation between the tested boom part and the reference straight line.
[0004] During the above-mentioned wire pulling process for detecting straightness, it is necessary to manually tighten the wire and ensure that it is parallel to the measured surface. The operation is cumbersome and the straightness error is large. It is difficult to accurately measure the straightness of the boom parts, which affects the measurement efficiency. Summary of the invention
[0005] In order to help solve the problem of time-consuming, labor-intensive and poor precision of manual wire-pulling measurement, which leads to low production efficiency, a detection frame provided in the present application adopts the following technical solution: it comprises two main beams, the main beams are provided with detection bars arranged perpendicular to the main beams, the length direction of the detection bars is parallel to the length direction of the main beams, the boom parts to be inspected are mounted on the main beams and fit with at least one detection bar, and a connecting component is provided between the two main beams.
[0006] Through the above technical scheme, when it is necessary to detect the straightness of the boom parts, the verticality between the detection baffle and the main beam and the flatness of the detection baffle are set within the required range, the boom parts to be detected are mounted on the main beam, and the length direction of the boom parts is aligned with the length direction of the detection baffle. The straightness detection of the boom parts is quickly completed by observing the degree of fit between the boom parts and the detection baffle. Compared with wire pulling detection, it reduces labor costs and the influence of manual operation on the accuracy of measurement results, saves time and effort, and improves detection accuracy and efficiency.
[0007] In a specific possible implementation manner, the connection assembly includes a side beam arranged between two main beams.
[0008] Through the above technical solution, the two main beams are connected by the side beams. The side beams can share part of the load and reduce the stress concentration of the main beams, thereby improving the bearing capacity of the entire structure and enhancing the stability and rigidity of the entire structure.
[0009] In a specific implementation scheme, two mounting blocks are provided on the surface of the side beam facing the detection baffle, and a plurality of conveying rollers are rotatably connected between the two mounting blocks, and the central axes of the plurality of conveying rollers are parallel to the length direction of the main beam.
[0010] Through the above technical solution, the rolling friction resistance of the conveyor roller is much smaller than the sliding friction resistance. When the boom parts are placed on the conveyor roller, they can be more easily slid along the conveyor roller to the detection baffle, which greatly reduces the labor intensity of manual handling, reduces the handling time, and improves the efficiency of straightness detection.
[0011] In a specific possible implementation manner, a plurality of support blocks are provided on the surface of the detection stop bar facing away from the connection assembly, and the plurality of support blocks are located between the detection stop bar and the main beam.
[0012] Through the above technical solution, the support block supports the detection baffle, reduces the possibility of deformation or displacement of the detection baffle under the action of external force, thereby affecting the detection accuracy, and improves the rigidity and stability of the detection baffle.
[0013] In a specific possible implementation scheme, a plurality of heightening blocks are provided on the main beam, and the boom parts to be inspected are mounted on the heightening blocks and are in contact with at least one inspection stop bar.
[0014] Through the above technical solution, the raising blocks provide a stable supporting surface for the boom parts, reducing the possibility of shaking or displacement of the boom parts during the inspection process. The raising blocks can also reduce the direct contact and friction between the boom parts and the main beam, thereby reducing the risk of wear and damage and facilitating the loading and unloading of the boom parts.
[0015] In a specific possible implementation scheme, a plurality of first support frames are provided on the surface of the main beam facing away from the detection baffle, and the plurality of first support frames are all located between the two main beams.
[0016] Through the above technical solution, the first support frame supports the main beam. During the detection process, the weight of the boom parts and other dynamic loads will act on the main beam. The first support frame can effectively share these loads, reduce the stress on the main beam, prevent the main beam from being deformed or damaged due to overload, and enhance the stability and rigidity of the entire structure.
[0017] In a specific possible implementation manner, a plurality of the first support frames are respectively provided with cross-arranged reinforcing ribs.
[0018] Through the above technical solution, the reinforcing ribs increase the local material thickness of the support frame, thereby enhancing its ability to resist deformation. When arranged crosswise, they form a stable network structure, further improving the strength and rigidity of the overall structure, sharing the load borne by the first support frame, and optimizing the stress distribution.
[0019] In a specific possible implementation scheme, a plurality of placement rods are provided on the surface of the main beam facing away from the connection assembly, and the boom parts to be inspected are mounted on the placement rods.
[0020] Through the above technical solution, the boom parts to be inspected can be placed in batches on the placement rod, reducing the time for reciprocating the boom parts and improving the inspection efficiency.
[0021] In a specific possible implementation manner, second support frames are respectively provided on the surfaces of the plurality of placement rods facing away from the detection baffle bar.
[0022] Through the above technical solution, the second support frame supports the placement rod, and can effectively share the load on the second support frame, reduce the stress on the placement rod, prevent the placement rod from being deformed or damaged due to overload, and improve the stability and rigidity of the placement rod.
[0023] In a specific possible implementation manner, a connecting rod is provided between a plurality of the second supporting frames.
[0024] Through the above technical solution, a plurality of second support frames are connected as a whole through connecting rods, which further improves the stability between the second support frames, optimizes the stress distribution, and improves the stability and rigidity of the placement rod.
[0025] To sum up, the present application has at least the following beneficial technical effects: when it is necessary to detect the straightness of the boom parts, the verticality between the detection bar and the main beam and the flatness of the detection bar are set within the required range, the boom parts to be detected are mounted on the main beam, and the length direction of the boom parts is aligned with the length direction of the detection bar. The straightness detection of the boom parts is quickly completed by observing the degree of fit between the boom parts and the detection bar. Compared with wire pulling detection, it reduces labor costs and the influence of manual operation on the accuracy of measurement results, saves time and effort, and improves detection accuracy and efficiency.

[0030] The following is combined with Figure 1-3 This application is described in further detail.
[0031] The embodiment of the present application discloses a detection rack.
[0032] Reference Figure 1 and Figure 2 The detection frame includes two main beams 1, and a detection bar 2 arranged perpendicular to the main beam 1 is fixedly connected to the main beam 1. In the embodiment of the present application, the detection bar is a long strip of carbon steel. Carbon steel has high strength and hardness, which enables the detection bar 2 made of carbon steel to withstand greater force and pressure. The surface hardness of carbon steel is high and the wear resistance is good. It is not easily subject to wear and deformation, which extends the service life of the detection bar 2.
[0033] Reference Figure 1 and Figure 2 , the length direction of the detection bar 2 is parallel to the length direction of the main beam 1, a number of padding blocks 7 are fixedly connected to the main beam 1, the boom parts to be detected are mounted on the padding blocks 7 and fit with at least one detection bar 2, and a connecting assembly 3 is provided between the two main beams 1. The detection bar 2 in the embodiment of the present application needs to have a flatness within 0.1mm of the fitting surface with the boom parts; the end surface of the padding block 7 facing away from the main beam 1 is used as the reference plane, and the verticality between the detection bar 2 and the padding block 7 is within 0.1mm.
[0034] Therefore, the raising block 7 provides a stable supporting surface for the boom parts, reducing the possibility of shaking or displacement of the boom parts during the inspection process. The raising block 7 can also reduce the direct contact and friction between the boom parts and the main beam 1, thereby reducing the risk of wear and damage and facilitating the loading and unloading of the boom parts.
[0035] Reference Figure 2 and Figure 3 A plurality of support blocks 6 are fixedly connected to the surface of the detection baffle 2 facing away from the connecting assembly 3. The plurality of support blocks 6 are located between the detection baffle 2 and the main beam 1. The support blocks 6 support the detection baffle 2, thereby reducing the possibility of deformation or displacement of the detection baffle 2 under the action of external force, thereby affecting the detection accuracy, and improving the rigidity and stability of the detection baffle 2.
[0036] Reference Figure 2 and Figure 3The connection assembly 3 includes a side beam disposed between two main beams 1. The two main beams 1 are connected by the side beams. The side beams in the embodiment of the present application can be made of rectangular tubes. The side beams can share part of the load and reduce the stress concentration of the main beams 1, thereby improving the bearing capacity of the entire structure and enhancing the stability and rigidity of the entire structure. Two mounting blocks 4 are welded on the surface of the side beam facing the detection baffle 2. A plurality of conveying rollers 5 are rotatably connected between the two mounting blocks 4. The central axes of the plurality of conveying rollers 5 are parallel to the length direction of the main beam 1.
[0037] Therefore, the rolling friction resistance of the conveyor roller 5 is much smaller than the sliding friction resistance. When the boom parts are placed on the conveyor roller 5, they can more easily slide along the conveyor roller 5 to the detection baffle 2 and fit with the detection baffle 2, which greatly reduces the labor intensity of manual handling, reduces the handling time, and improves the efficiency of straightness detection.
[0038] Reference Figure 2 and Figure 3 A plurality of first support frames 8 are installed on the surface of the main beam 1 facing away from the detection baffle 2, and the plurality of first support frames 8 are located between the two main beams 1. In the embodiment of the present application, the plurality of first support frames 8 are located directly below the side beams, and cross-arranged reinforcing ribs 9 are welded on the plurality of first support frames 8. The reinforcing ribs 9 increase the local material thickness of the support frames to enhance their ability to resist deformation. In the case of a cross-arrangement, they form a stable network structure, further improving the strength and rigidity of the first support frames 8, sharing the load borne by the first support frames 8, and optimizing the stress distribution.
[0039] Therefore, the first support frame 8 supports the main beam 1. During the detection process, the weight of the boom parts and other dynamic loads will act on the main beam 1. The first support frame 8 can effectively share these loads, reduce the stress on the main beam 1, and prevent the main beam 1 from being deformed or damaged due to overload, thereby enhancing the stability and rigidity of the entire structure.
[0040] Reference Figure 2 and Figure 3 , a plurality of placement rods 10 are welded on the surface of the main beam 1 away from the connection assembly 3, and the boom parts to be detected are mounted on the placement rods 10. The placement rods 10 in the embodiment of the present application can be made of channel steel, and the boom parts to be detected can be placed on the placement rods 10 in batches, which reduces the time for reciprocating the boom parts and improves the detection efficiency. Second support frames 11 are respectively welded on the surfaces of the placement rods 10 away from the detection baffle 2, and connecting rods 12 are fixedly connected between the plurality of second support frames 11. The plurality of second support frames 11 are connected as a whole through the connecting rods 12. The connecting rods 12 in the embodiment of the present application can be made of angle steel, which further improves the stability between the second support frames 11, optimizes the stress distribution, and improves the stability and rigidity of the placement rods 10.
[0041] Therefore, the second support frame 11 supports the placement rod 10. The second support frame 11 can effectively share the load, reduce the stress on the placement rod 10, prevent the placement rod 10 from being deformed or damaged due to overload, and improve the stability and rigidity of the placement rod 10.
[0042] The implementation principle of the embodiment of the present application is: when it is necessary to detect the straightness of the boom parts, the verticality between the detection baffle 2 and the main beam 1 and the flatness of the detection baffle 2 need to be set within the required range, and the boom parts to be detected are mounted on the conveyor roller 5, and the boom parts slide along the conveyor roller 5 and move to the main beam 1 and fit the detection baffle 2. The straightness detection of the boom parts is quickly completed by observing the degree of fit between the boom parts and the detection baffle 2 in the length direction. Compared with wire pulling detection, it reduces labor costs and reduces the influence of manual operation on the accuracy of measurement results, saves time and effort, and improves detection accuracy and efficiency.
