Description

Technical Field

[0001] This invention relates to the field of adhesive bonding fixtures, and more particularly to a pressure device for steel structure assembly and its usage method. Background Technology

[0002] Some underwater steel structures require the adhesion of special materials. For example, the application of a certain vulcanized rubber material on a submarine involves bonding it to the steel structure surface using an adhesive. During the application process, pressure needs to be applied to the vulcanized rubber material to meet the adhesion requirements. The existing process uses a mechanical clamping device, which involves welding a bracket to the steel structure, fixing the mechanical clamping device to the bracket, and then applying pressure to the material.

[0003] An existing invention patent application with publication number CN108006033A discloses an adhesive bonding fixture, which includes a frame, a pressure applying mechanism, and a clamping mechanism; the top surface of the frame is provided with a mounting groove penetrating along the thickness direction; the clamping mechanism includes a main clamping body and a secondary clamping body, the secondary clamping body being detachably connected to the frame, and the main clamping body being disposed on the frame; the pressure applying mechanism is connected above the support.

[0004] In the above technical solution, the specimen is clamped by a clamping mechanism and then pressure is applied by a pressure-applying mechanism to make the bonded structure more solid after curing. However, the pressure plate used to hold the specimen is an integral structure and is fixedly connected to the fixing screw, which makes the angle of the pressure plate non-adjustable. Therefore, this kind of holding structure is not suitable for pressurizing irregular steel structures. It cannot adapt to the irregular surface of the steel structure and has poor adaptability. Therefore, a device that can change the angle and adapt to pressurizing irregular surfaces is needed. Summary of the Invention

[0005] In view of this, the present invention proposes a pressurizing device for steel structure assembly that can adjust the pressing angle according to the shape of the steel structure and has stable operation, as well as its method of use, to solve the problem that the existing pressurizing mechanism has a fixed structure and the angle is not adjustable, which limits its applicable range.

[0006] The technical solution of this invention is implemented as follows:

[0007] On one hand, the present invention provides a pressurizing device for steel structure assembly and its method of use, comprising a load-bearing beam, a compression rod, a universal joint, a pressure plate, and a buffer component, wherein,

[0008] One end of the compression member is threadedly connected to the load-bearing beam;

[0009] The universal joint is located on the end of the compression member away from the load-bearing beam;

[0010] The pressure plate is located on the end of the universal joint furthest from the pressure rod.

[0011] One end of the buffer is connected to the load-bearing beam, and the other end is connected to the pressure plate. The buffer is used to buffer the displacement of the pressure plate through elastic expansion and contraction when the universal joint rotates.

[0012] Based on the above technical solutions, preferably, the buffer component includes a connecting frame, a connecting rod, and a tension spring, wherein,

[0013] The connecting frame is connected to the load-bearing beam;

[0014] The connecting rod is connected to the connecting frame;

[0015] One end of the tension spring is connected to the pressure plate, and the other end of the tension spring is fixed relative to the connecting rod.

[0016] Based on the above technical solutions, preferably, at least two load-bearing beams are provided, and at least two pressure plates are provided on each load-bearing beam. The pressure plates are arranged in a rectangular array, and the corners of the pressure plates have hanging rings.

[0017] The buffer is equipped with at least four tension springs, each of which is connected to a hanging ring on a pressure plate.

[0018] Based on the above technical solutions, preferably, the pressure plates arranged in a rectangular array have gaps between them, the connecting rod is a hollow tubular structure, one end of the connecting rod passes through the connecting frame, the other end of the connecting rod corresponds to the intersection of the gaps, and the hollow part of the connecting rod is used for gas flow.

[0019] Based on the above technical solutions, preferably, the end of the connecting rod away from the connecting frame is provided with an external thread, and the buffer also includes a nut sleeve, a connecting sleeve, and a hanging plate, wherein...

[0020] The nut sleeve is screwed into the external thread on the connecting rod;

[0021] The connecting sleeve and the nut sleeve are circumferentially rotatably connected, and the connecting sleeve is axially positioned relative to the nut sleeve;

[0022] The mounting plate is positioned at the end of the connecting cylinder furthest from the nut cylinder;

[0023] The end of the tension spring furthest from the pressure plate is attached to the hanging plate.

[0024] Based on the above technical solutions, the preferred embodiment also includes an air supply pipe, which is arranged parallel to the load-bearing beam and connected and penetrates the connecting rod.

[0025] Based on the above technical solutions, preferably, the connecting frame overlaps between two load-bearing beams, and the part of the connecting frame that connects to the connecting rod protrudes towards the pressure plate, and the air supply pipe is laid in the recess of the connecting frame.

[0026] Based on the above technical solutions, preferably, the pressure rod and the connecting rod are arranged parallel to each other, and the end of the pressure rod away from the universal joint has a prismatic structure.

[0027] Based on the above technical solutions, preferably, it also includes a mounting rod, a magnetic chuck, and a force sensor, wherein,

[0028] The mounting rod is set parallel to the compression rod. The mounting rod includes a first section and a second section. The first section is set at the end of the load-bearing beam, and the second section is connected to the magnetic chuck.

[0029] One end of the tension sensor is connected to the first segment, and the other end is connected to the second segment.

[0030] On the other hand, the present invention provides a method for using a pressurizing device for steel structure assembly, comprising the following steps:

[0031] S1. Bond vulcanized rubber material to the steel structure, and then fix the load-bearing beam to the steel structure.

[0032] S2. Connect the air supply pipe to the fan. The fan outputs ambient temperature airflow. After the ambient temperature airflow passes through the air supply pipe and the connecting rod, it blows through the gaps to sweep the surface of the vulcanized rubber material to remove the adhering foreign matter.

[0033] S3. Rotate the pressure bar to bring the pressure plate closer to the vulcanized rubber material until the pressure plate presses the vulcanized rubber material onto the steel structure;

[0034] S4. The fan connected to the air supply pipe outputs hot airflow to purge the gap.

[0035] S5. After the pressure on the vulcanized rubber material is completed and the glue is completely solidified, rotate the pressure rod to detach the pressure plate from the vulcanized rubber material, and at the same time, stop the blower.

[0036] The pressurizing device for steel structure assembly and its method of use of the present invention have the following advantages over the prior art:

[0037] (1) By setting a universal joint for connecting the pressure plate and the pressure rod, the pressure plate can be rotated and adjusted by the universal joint when the pressure rod applies pressure, so as to adaptively fit the steel structure surface, thus making this pressurizing device suitable for pressurizing the surface material of irregular steel structures; at the same time, the buffer can rely on elastic telescopic movement to buffer the rotation of the pressure plate, avoiding the problem of the pressure plate rotating too much during the adjustment process and causing collision damage, so as to improve the reliability and safety of the application;

[0038] (2) There are at least four pressure plates and at least four tension springs for the buffer. The pressure plates are arranged in a rectangular array structure, so that a single buffer can buffer multiple pressure plates when they are adjusted. This can reduce the number of buffers installed and improve the buffering effect on the pressure plates.

[0039] (3) The pressure plates are set in an array structure with gaps between them. By setting the connecting rod of the buffer to a hollow tubular structure, it is convenient to connect the fan. The airflow output by the fan can blow through the gap to remove the material bonded to the steel structure surface, thereby removing foreign matter adhering to the material surface and preventing material damage caused by pressing on foreign matter during pressurization. At the same time, hot airflow can also be blown to improve the adhesive curing efficiency.

[0040] (4) This pressurizing device uses a magnetic chuck to attract and fix the steel structure. This eliminates the need for auxiliary fixing by welding threaded columns and brackets, as is the case with traditional pressurizing devices. This helps to avoid interference with the laying of materials, thereby improving the laying efficiency. At the same time, it does not damage the surface of the steel structure, which helps to ensure the laying effect. Attached Figure Description

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figures 1-12 As shown, the pressurizing device for steel structure assembly of the present invention includes a bearing beam 1, a pressure bar 2, a universal joint 3, a pressure plate 4, a buffer 5, an air supply pipe 6, a mounting rod 7, a magnetic chuck 8, a tension sensor 9, and an electrical control box 10.

[0057] This pressure device for steel structure assembly is used for pressurizing and fixing adhesive materials on the surface of steel structures, such as for pressurizing and fixing vulcanized rubber materials after they have been laid on the surface of steel structures, so that the vulcanized rubber materials can be bonded more firmly.

[0058] The pressurizing device for assembling this steel structure consists of several pressurizing units. Each pressurizing unit includes the aforementioned load-bearing beam 1, pressure bar 2, universal joint 3, pressure plate 4, buffer 5, mounting rod 7, magnetic chuck 8, tension sensor 9, and electrical control box 10.

[0059] like Figures 1-6As shown, one end of the pressure rod 2 is connected to the bearing beam 1 by a threaded connection; the universal joint 3 is located on the end of the pressure rod 2 away from the bearing beam 1; the pressure plate 4 is located on the end of the universal joint 3 away from the pressure rod 2; one end of the buffer 5 is connected to the bearing beam 1 and the other end is connected to the pressure plate 4. The buffer 5 is used to buffer the displacement of the pressure plate 4 by elastic expansion and contraction when the universal joint 3 rotates.

[0060] As described above, when using this pressurizing device, the bearing beam 1 needs to be fixedly connected to the steel structure first. Then, the pressure plate 4 is adjusted by relying on the pressure rod 2. Since the pressure rod 2 is connected to the bearing beam 1 by a thread, and the end of the pressure rod 2 is connected to the pressure plate 4 by a universal joint 3, when the pressure rod 2 is rotated, the pressure plate 4 will move closer to the surface of the steel structure, so as to press the material pasted on the surface of the steel structure onto the steel structure, so that after the adhesive is cured, the connection between the steel structure and the material pasted on the surface is more firm.

[0061] Due to the universal joint 3, the pressure plate 4 can be tilted and adjusted to fit the steel structure surface during the advancement of the pressure rod 2, enabling this pressurizing device to adapt to irregular steel structure surfaces and thus having a wide range of applications. Irregular steel structures specifically refer to steel structures with protruding ridges on their surfaces, but with different tilt angles on the steel structure plates on both sides of the ridges, or steel structures with undulating surfaces.

[0062] During the use of this device, there are processes of installing the device onto the steel structure and removing the device from the steel structure. During these processes, since the pressure plate 4 and the pressure rod 2 are connected by a universal joint 3, the pressure plate 4 will swing uncontrollably due to the universal connection when the device is moved. This can easily cause the universal joint 3 to be damaged due to excessive displacement.

[0063] See details Figure 12 The universal joint 3 includes a ball seat 31 with a semi-circular groove for holding a universal ball 32. The universal ball 32 has an end rod 34 for connecting to the pressure rod 2. The diameter of the end rod 34 is smaller than the diameter of the universal ball 32. A cover plate 33 is fastened to the ball seat 31 and has a circular hole for the end rod 34 to pass through. The diameter of the circular hole is larger than the diameter of the end rod 34 but smaller than the diameter of the universal ball 32. This can limit the movement of the universal ball 32 and give the universal ball 32 a certain angle adjustment function.

[0064] However, regardless of the type of universal joint structure, there will be certain adjustment range limitations. For example, in the universal joint structure mentioned above, when the displacement exceeds the limit, the end rod 34 will hit the inner wall of the round hole of the cover plate 33. In particular, after the ball seat 31 is connected to the pressure plate 4, the weight of the pressure plate 4 will increase the impact force. In order to avoid damage to the connection structure, the buffer 5 is required to buffer during the disassembly and assembly of this pressurizing device.

[0065] Specifically, the buffer 5 provides cushioning through elastic extension and contraction. It can be an elastic component such as a tension spring or a gas spring. Through its own elastic tension, it limits and slows down the swing amplitude of the pressure plate 4, thereby achieving a safety protection effect. At the same time, the limiting effect of the buffer 5 can also prevent the pressure plate 4 from rotating through the universal joint 3. Of course, this structure does not limit the buffer 5 to be composed only of elastic components such as tension springs and gas springs. It can include components used to assist in the installation of tension springs / gas springs.

[0066] like Figures 8-11 As shown, the buffer 5 includes a connecting frame 51, a connecting rod 52, and a tension spring 53. The connecting frame 51 is connected to the load-bearing beam 1; the connecting rod 52 is connected to the connecting frame 51; one end of the tension spring 53 is connected to the pressure plate 4, and the other end of the tension spring 53 is fixed relative to the connecting rod 52.

[0067] As described above, when installing the buffer 5, first set up the connecting frame 51 and the connecting rod 52 and connect them to the bearing beam 1. Then, the tension spring 53 can be connected to the connecting rod 52. This can shorten the length of the tension spring 53 and shorten its stroke. This not only makes it easier to install the tension spring 53, but also better limits the swing amplitude of the pressure plate 4.

[0068] like Figure 6 As shown, the pressure rod 2 is arranged parallel to the connecting rod 52, and the end of the pressure rod 2 away from the universal joint 3 has a prismatic structure;

[0069] As described above, by setting the end of the pressure rod 2 into a prism-shaped structure, it is convenient to rotate the pressure rod 2 with a wrench, thereby realizing the displacement adjustment of the pressure plate 4 and improving the convenience of operation.

[0070] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, at least two load-bearing beams 1 are provided, and at least two pressure plates 4 are provided on each load-bearing beam 1. The pressure plates 4 are arranged in a rectangular array, and the corners of the pressure plates 4 have hanging rings 41. The buffer 5 is provided with at least four tension springs 53, and each tension spring 53 is connected to a hanging ring 41 on a pressure plate 4.

[0071] As described above, by arranging multiple pressure plates 4 in an array, each pressure plate 4 can be individually adjusted to the angle of the steel structure surface. At the same time, a buffer 5 can be connected to at least four pressure plates 4 by a tension spring 53, which can reduce the number of buffers 5 installed. Preferably, the pressure plates 4 adopt a polygonal structure.

[0072] Specifically, when setting the hanging ring 41, multiple rings can be set on the pressure plate 4 to facilitate the connection between the pressure plate 4 and multiple buffers 5, thereby making the displacement of the pressure plate 4 more stable.

[0073] Furthermore, several buffers 5 are provided, such as... Figure 1 As shown, it displays 16 pressure plates 4 and several buffer components 5. The two pressure plates 4 in the middle are connected to four buffer components 5. Thus, the middle pressure plates 4 have better stability and are less prone to damage than the outer pressure plates 4. Although the outer pressure plates 4 have poor stability, they have the advantage of being easy to disassemble and assemble, and are easy to replace when the buffer components 5 are damaged.

[0074] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the end of the connecting rod 52 away from the connecting frame 51 is provided with an external thread 501. The buffer 5 also includes a nut sleeve 54, a connecting sleeve 55, and a hanging plate 56. The nut sleeve 54 is screwed into the external thread 501 on the connecting rod 52. The connecting sleeve 55 is circumferentially rotatably connected to the nut sleeve 54, and the connecting sleeve 55 is axially positioned relative to the nut sleeve 54. The hanging plate 56 is disposed on the end of the connecting sleeve 55 away from the nut sleeve 54. The end of the tension spring 53 away from the pressure plate 4 is attached to the hanging plate 56.

[0075] As described above, to facilitate the connection between the tension spring 53 and the connecting rod 52, the tension spring 53 can be first connected to the hanging plate 56, and then the nut sleeve 54 can be connected to the external thread 501 of the connecting rod 52. This device can be used in parallel with multiple pressurizing units, for example... Figure 1 Four pressurization units are shown. Spring 53 is connected by hooking onto hanging plate 56, which also facilitates the assembly of this device.

[0076] The connecting rod 52 mentioned above can be made of high-strength steel for use in connecting the pressurized unit during assembly.

[0077] like Figure 4 and Figure 7 As shown, the pressure plates 4 arranged in a rectangular array have a gap 100 between them. The connecting rod 52 is a hollow tubular structure. One end of the connecting rod 52 passes through the connecting frame 51, and the other end of the connecting rod 52 corresponds to the intersection of the gap 100. The hollow part of the connecting rod 52 is used for gas flow.

[0078] As described above, when multiple pressure plates 4 are installed, a gap 100 is left between the pressure plates 4 to ensure that each pressure plate 4 can be tilted and adjusted via the universal joint 3. This allows the pressure plates 4 to have tilting space to adapt to the surface of the steel structure. To fully utilize this gap 100, the connecting rod 52 is designed as a hollow tubular structure. Thus, when the pressure plates 4 apply pressure to the surface material of the steel structure, the connecting rod 52 can be connected to a fan, and then the fan can blow air through the connecting rod 52 and the gap 100 to blow away the material adhered to the steel structure surface, preventing foreign objects from being pressed onto the material surface and avoiding damage to the steel structure surface material caused by the pressure plates 4 pressing against foreign objects. When the steel structure and the material are bonded together with thermosetting adhesive, the fan can blow hot air to heat the material and adhesive, thereby accelerating the curing of the adhesive. This also effectively solves the problem that the gap 100 cannot be pressurized and fixed, improving the bonding strength of the material at the gap 100.

[0079] like Figure 5 As shown, the air supply pipe 6 is arranged parallel to the supporting beam 1, and the air supply pipe 6 is connected to and passes through the connecting rod 52;

[0080] As described above, when multiple buffer components 5 are set, in order to reduce the number of fans, an air supply pipe 6 can be set. First, connect the connecting rod 52 of the buffer component 5 to the air supply pipe 6, and then connect the air supply pipe 6 to the fan, so that the airflow is diverted through the air supply pipe 6 to the connecting rod 52 of each buffer component 5.

[0081] Furthermore, the connecting frame 51 overlaps between the two load-bearing beams 1, and the part of the connecting frame 51 that connects to the connecting rod 52 protrudes toward the pressure plate 4, and the air supply pipe 6 is laid in the recess of the connecting frame 51.

[0082] As described above, by setting the connecting bracket 51 to protrude toward the pressure plate 4, a recess for accommodating the air supply pipe 6 is formed, which further improves the compactness of the pressurization device structure.

[0083] like Figures 1-6 As shown, the mounting rod 7 is arranged parallel to the pressure rod 2. The mounting rod 7 includes a first section 71 and a second section 72. The first section 71 is located at the end of the bearing beam 1, and the second section 72 is connected to the magnetic chuck 8. One end of the tension sensor 9 is connected to the first section 71, and the other end is connected to the second section 72.

[0084] As described above, this pressurizing device is fixed by a magnetic chuck 8. In specific applications, the magnetic chuck 8 is used to attach the steel structure for fixed connection. Then, the pressure rod 2 is rotated so that the pressure plate 4 abuts against the material on the surface of the steel structure to achieve pressurization and fixation. Due to the rotational displacement of the pressure rod 2, the bearing beam 1 will be subjected to force, which will then be transmitted to the mounting rod 7 and the tension sensor 9. As the pressure rod 2 is continuously tightened, the first section 71 and the second section 72 of the mounting rod 7 are subjected to separation forces. The tension sensor 9 will display the force reading, thereby measuring the pressure of the pressure plate 4 on the material, thus ensuring that the pressure meets the material's pressurization requirements.

[0085] Since the magnetic chuck is used to attach and fix the steel structure, there is no need to use components such as welded threaded columns and brackets for auxiliary fixation as with traditional pressure devices. This helps to avoid interference with material laying, thereby improving laying efficiency. At the same time, it does not damage the surface of the steel structure, which helps to ensure the laying effect.

[0086] like Figure 1 As shown, the electrical control box 10 is installed on the magnetic chuck 8. The electrical control box 10 is electrically connected to the magnetic chuck 8 and the tension sensor 9 to control the movement of the magnetic chuck 8 and for pressure detection. This is existing technology and will not be described in detail.

[0087] The method of using the pressure device for steel structure assembly, as described above, includes the following steps:

[0088] S1. Bond vulcanized rubber material to the steel structure, and then fix the load-bearing beam 1 relative to the steel structure;

[0089] S2. Connect the air supply pipe 6 to the fan. The fan outputs ambient temperature airflow. After the ambient temperature airflow flows through the air supply pipe 6 and the connecting rod 52, it passes through the gap 100 to blow the surface of the vulcanized rubber material to remove the adhering foreign matter.

[0090] S3. Rotate the pressure rod 2 to bring the pressure plate 4 closer to the vulcanized rubber material until the pressure plate 4 presses the vulcanized rubber material onto the steel structure.

[0091] S4, the fan connected to the air supply pipe 6 outputs hot airflow to purge the gap 100 with hot airflow;

[0092] S5. After the pressure on the vulcanized rubber material is completed and the glue is completely solidified, rotate the pressure rod 2 to separate the pressure plate 4 from the vulcanized rubber material, and at the same time, the blower stops.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
