DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1 In an embodiment of the present invention, a steel structure for installing a sound barrier includes an upper fastener and a lower fastener, the lower fastener is an I-beam 1, and the top of the I-beam 1 is detachably connected to the upper fastener through a connecting piece 2; a gap is provided between the upper fastener and the lower fastener, and the connecting piece 2 divides the gap into two installation grooves for accommodating the sound barrier 7; through the cooperation of the upper fastener and the lower fastener, the sound barrier 7 is clamped and limited from both sides to realize the installation operation of the sound barrier 7;

[0035] As an example of steel structure, please refer to Figure 1 The upper fastener includes two symmetrically arranged U-shaped channel steels 4, the two U-shaped channel steels 4 are respectively located on both sides of the connecting piece 2, and the two U-shaped channel steels 4 are fixedly connected by mounting bolts 5, the middle of the mounting bolts 5 penetrates the connecting piece 2, and the two ends of the mounting bolts 5 pass through the two U-shaped channel steels 4 and are respectively threadedly locked with two nuts to achieve a stable connection between the two U-shaped channel steels 4 and the connecting piece 2;

[0036] The bottoms of the two U-shaped channel steels 4 are fixedly connected with limiting baffles 6, which block and limit the sides of the two sound barriers 7, thereby controlling the distance between the two sound barriers 7, avoiding direct contact between the two sound barriers 7 and subsequent extrusion deformation, which would damage the sound barriers 7 and affect the sound insulation effect.

[0037] When the present invention is installed and used, the connecting plate 2 is passed through the gap between the two sound barriers 7, and then two U-shaped channel steels 4 are placed on both sides of the connecting plate 2, and then the two U-shaped channel steels 4 and the connecting plate 2 are locked and fixed by using the installation bolts 5 to achieve the installation and fixation of the sound barrier 7.

[0038] As a second example of steel structure, please refer to Figure 2 The fasteners thereon include two symmetrically arranged angle brackets 8, which are L-shaped channel steels, and the inner wall of the L-shaped channel steel is fixedly connected with a reinforcing plate, and the two L-shaped channel steels are also fixed by installing bolts 5. The fixing method is different from that of the first embodiment in that: the tops of the two angle brackets 8 are jointly engaged and connected with a snap-on cover plate 9, and the two side edges of the snap-on cover plate 9 are bent inward, and the bent part is snapped into the gap between the L-shaped channel steel sound barriers 7, so as to realize the snap-on fixation of the two L-shaped channel steels; the rest of the structure is the same as that of the first embodiment.

[0039] In order to reflect the advantages of the steel structure of the present application, the structural style of the steel structure in the prior art targeted by the present application is described; specifically, please refer to Figure 3 , Figure 3 The structure of the steel structure commonly used for installing the sound barrier 7 in the prior art is shown. It adopts an I-shaped steel structure with a longer central part (hereinafter referred to as the prototype steel 10). During installation, the prototype steel 10 needs to be passed through the gap between the two sound barriers 7 as a whole, and then angle brackets 8 are set on both sides of the prototype steel 10 to achieve the limit between the prototype steel 10 and the sound barrier 7; because the upper and lower surfaces of the prototype steel 10 have a large width, when the distance between the two sound barriers 7 is small, the prototype steel 10 cannot pass through, which brings difficulties to the installation and construction operation. Therefore, the present application makes an improvement on this problem. A connecting piece 2 is arranged on the top of the I-beam 1, and the connecting piece 2 is used to pass through the gap between the sound barriers 7. The thickness of the connecting piece 2 is much smaller than the width of the upper and lower plate materials of the I-beam 1, so it can pass through the smaller gap. The connecting piece 2 is then fixed by the upper fastener arranged on the other side, and the sound barrier 7 is installed by squeezing and locking the I-beam 1 on both sides. Compared with the existing steel structure, the steel structure of the present application has better flexibility in use and can adapt to the installation needs between sound barriers 7 with different interval widths.

[0040] Since the present application proposes a new type of steel structure, compared with the existing steel structure, the prototype steel 10 in the prior art is integrally formed, while the steel structure of the present application includes two split components (i.e., the I-beam 1 and the connecting piece 2), which need to be produced and welded separately; since there is no mounting structure at the welding position, external force constraints are required during the welding process to ensure the vertical docking between the connecting piece 2 and the I-beam 1 and maintain a stable posture, so as to facilitate the welding operation. The method of manually holding and pressing to assist in positioning the connecting piece 2 and the I-beam 1 consumes manpower and affects the overall production efficiency of the welding operation. Therefore, in order to realize the production of such a steel structure, please refer to Figure 4 The present application provides a processing device for a steel structure for installing a sound barrier, including a base 101, and a limited position conveying mechanism is provided at one end of the base 101. Figure 5 The position-limiting conveying mechanism includes an upper position-limiting assembly and a lower position-limiting assembly, the upper position-limiting assembly is used to convey the connecting piece 2, and the lower position-limiting assembly is used to convey the I-beam 1; a welding mechanism 401 is provided in the middle of the base 101, which is used to weld the connecting piece 2 to the I-beam 1, and the specific structure of the welding mechanism 401 is implemented using existing welding devices; by setting up the position-limiting conveying mechanism, the upper position-limiting assembly and the lower position-limiting assembly are used to perform position-limiting and automatic conveying operations with the connecting piece 2 and the I-beam 1 respectively, so that the two can pass through the welding mechanism 401 in a stable vertical docking posture, thereby facilitating the welding operation.

[0041] In one embodiment, since the connecting piece 2 has a certain length, in order to prevent the connecting piece 2 from bending and tilting laterally after being separated from the upper limit assembly during transportation, causing the welding position to shift and thus affecting the welding operation; the present application provides a docking assembly at the other end of the base 101 for limiting the posture of the connecting piece 2; please refer to Figure 7 The docking assembly includes a docking frame 301, and driving guide rails 302 are fixedly installed on both sides of the inner wall of the docking frame 301. A hanging frame 303 is slidably installed on the inner wall of the driving guide rail 302. A direction adjustment motor 304 is fixedly installed on one side of the hanging frame 303. A roller frame 305 is fixedly connected to the output end of the direction adjustment motor 304. A docking roller 306 is rotatably installed on the inner wall of the roller frame 305. During the transportation process of the connecting piece 2, pay attention to inserting the end of the connecting piece 2 between the two docking rollers 306. By setting the driving guide rail 302, the hanging frame 303 is driven to move, and then the The two docking rollers 306 are close to each other, and the connecting piece 2 is clamped and limited by both sides; in order to limit and correct the connecting piece 2 when it is tilted, the present application sets a steering motor 304 to adjust the posture of the docking rollers 306, that is, the two docking rollers 306 are adjusted to rotate synchronously by the synchronous rotation of the two steering motors 304, so that the connecting piece 2 can pass stably between the two docking rollers 306, and then the rotation and resetting action of the two adjustment motors drives the two docking rollers 306 to be upright again, thereby driving the tilted connecting piece 2 to twist and be vertical.

[0042] In one embodiment, see Figure 5 The lower limit assembly includes a limit groove, and limit pushing units are arranged on both sides of the inner wall of the limit groove. The limit pushing unit includes a pushing motor 102. The output end of the pushing motor 102 is fixedly connected with a pushing disk. When in use, the pushing disks on both sides are in close contact with the two sides of the I-beam 1 respectively, and the rotation of the pushing motor 102 drives the pushing disk to rotate, and the friction force is used to push the I-beam 1 to move, thereby realizing automatic transportation of the I-beam 1.

[0043] In one embodiment, the pushing disk includes an upper disk body 1031 and a lower disk body 1032 arranged in parallel. In order to increase the pushing force of the pushing disk as a whole on the I-beam 1, the edges of the upper disk body 1031 and the edges of the lower disk body 1032 are fixedly connected with friction pads.

[0044] In one embodiment, the distance between the top surface of the upper plate 1031 and the bottom surface of the lower plate 1032 is consistent with the distance between the upper and lower side plates of the I-beam 1, so as to achieve stable limiting support for the I-beam 1;

[0045] In one embodiment, in order to achieve stable positioning of I-beams 1 of different heights, a plurality of equally spaced adjustment members 104 are provided between the upper plate 1031 and the lower plate 1032. The adjustment members 104 are used to adjust the distance between the upper plate 1031 and the lower plate 1032; see Figure 6 The adjusting member 104 includes a fixing bolt 1042, the top of the fixing bolt 1042 is fixedly connected to the bottom of the upper disk body 1031, the bottom of the fixing bolt 1042 is threadedly connected with an adjusting sleeve 1041, the bottom of the adjusting sleeve 1041 is fixedly connected with a switching block 1044, the switching block 1044 is embedded in the top of the lower disk body 1032 and is rotatably connected to the top of the lower disk body 1032, and the outer wall of the adjusting sleeve 1041 is fixedly connected with an adjusting ring 1043; by setting the adjusting member 104, the adjusting sleeve 1041 is rotated by using the adjusting ring 1043 to change the ejection distance of the adjusting sleeve 1041, thereby driving the distance between the upper disk body 1031 and the lower disk body 1032 to meet the transportation needs of I-beams 1 of different heights.

[0046] In one embodiment, in order to improve the adjustment convenience of each adjustment member 104, the present application rotatably sets an adjustment disk 1033 between the upper disk body 1031 and the lower disk body 1032, and the outer wall of the adjustment disk 1033 is meshed and connected with the outer wall of each adjustment ring 1043, so that the rotation of the adjustment disk 1033 can drive the synchronous rotation of each adjustment ring 1043, thereby realizing synchronous adjustment of each adjustment member 104.

[0047] In one embodiment, the upper limit assembly includes a guide frame 201, both ends of which are provided with through grooves for the connecting piece 2 to pass through, the bottom height of the through groove is consistent with the top height of the I-beam 1, and both sides of the inner wall of the guide frame are fixedly connected with mounting frames 202, and the inner walls of the two mounting frames 202 are rotatably connected with mounting rollers 203, and the connecting piece 2 is pushed by the rotation of the mounting rollers 203; specifically, the outer wall of the mounting roller 203 is fixedly connected with a pushing pad 204, so as to increase the friction between the mounting roller 203 and the connecting piece 2 and improve the pushing stability; further, the pushing pad 204 is arranged to be tilted downward, so that when the mounting roller 203 rotates, it can generate a certain amount of tilted downward pushing force, so as to push the connecting piece 2 downward and ensure the stable contact between the bottom of the connecting piece 2 and the top surface of the I-beam 1.

[0048] In one embodiment, if the cooling speed of the steel structure is too fast after welding, the welding strength will be affected; in order to reduce the welding cooling speed, it is possible to consider setting a heating mechanism on one side of the welding mechanism 401, and heating the contact position (i.e., the welding position) between the connecting plate 2 and the I-beam 1 by the heating mechanism, so as to reduce the cooling speed of the welding position and ensure the welding quality. The specific structure of the heating mechanism can be implemented using existing technical means.

[0049] In one embodiment, see Figure 8 This embodiment provides a possible style of a heating mechanism, which includes an air supply frame 501, an air supply slot 505 is opened on one side of the air supply frame 501, an electric heating tube 503 is fixedly installed in the middle of the inner wall of the air supply frame 501, and an air inlet pipe 506 is fixedly connected to the other side of the air supply frame 501. One end of the air inlet pipe 506 is fixedly connected to the output end of an external air pump. The electric heating tube 503 and the air inlet pipe 506 are used to transport hot air to the welding position through the air supply slot 505 to achieve heating.

[0050] In one embodiment, in order to improve the stability of the flow of air supply gas, an air supply hood 502 is fixedly connected to one end of the air inlet pipe 506 close to the electric heating tube 503, and an air guide plate 504 is fixedly connected to one side of the inner wall of the air supply frame 501. One side of the air guide plate 504 is set as an inclined surface so that the gas is concentrated in the direction of the air supply groove 505.

[0051] When the present invention is used, the I-beam 1 is placed in the limiting groove, and the connecting piece 2 is placed in the through groove, and the connecting piece 2 is adjusted so that the bottom of the connecting piece 2 is in close contact with the top of the I-beam 1, and the end of the connecting piece 2 is aligned with the end of the I-beam 1;

[0052] Then, the push motor 102 drives the push disk to rotate, pushes the I-beam 1 to move, and at the same time, the installation roller 203 rotates to drive the connecting piece 2 to move synchronously. When the I-beam 1 and the connecting piece 2 move to the position of the welding mechanism 401, the welder performs welding operation on the docking position of the two. When the welding position passes through the heating mechanism, the external air pump is started to transport gas to the air supply frame 501 through the air supply pipe, and the air is blown to the electric heating pipe 503 by the air supply hood 502. The electric heating pipe 503 starts to heat and heat the passing airflow, and then the air guide plate 504 guides the air, and the air is sent out through the air supply slot 505 to the welding position of the I-beam 1 and the connecting piece 2 to avoid the temperature of the welding position from dropping rapidly. Then, the push disk and the installation roller 203 continue to rotate to push and discharge the welded I-beam 1 and the connecting piece 2, and they are taken over by manual or external material receiving equipment.
