[0002] As the main measure for sound insulation and noise reduction, sound barriers are widely used in road and bridge construction projects. In particular, metal sound barriers have been tested and developed in practice for their excellent performance.

[0003] Currently, sound barrier installation structures typically consist of barrier panels and a steel frame. The panels are slotted into the corresponding H-shaped steel webs. H-shaped steel, a cost-effective material with a well-balanced cross-sectional area and high strength, offers advantages such as strong bending resistance, simple construction, cost savings, and lightweight construction. It has been widely used in rail transit.

[0004] When processing steel frames, it is necessary to weld the ends of the steel columns together with accessories such as the base plate, connecting plate and stiffening plate. Most manufacturers in the industry use manual welding with a low degree of mechanization. Due to the high quality requirements of steel structure welding, the welding operators are required to be highly professional. The manual operation process has poor stability and high work intensity, and the welding efficiency is low, making it difficult to adapt to large-scale production requirements. Utility Model Content

[0005] The purpose of the utility model is to provide a welding platform for sound barrier frame steel, which has the characteristics of stable welding process, consistent standards, excellent welding quality and high production efficiency.

[0011] The surface of the rotating ring is provided with vertical and horizontal grooves, and the support plates of the rollers are respectively placed in the grooves. The support plates are provided with sliding grooves, and the limiting pins are installed in the sliding grooves to achieve the positioning of the support plates and the grooves;

[0012] A cutting mechanism is provided at the front of the inner rail of the frame, and a bridge of the cutting mechanism is placed between two adjacent guide vertical plates, and a punching head and a cutting saw blade are provided in the bridge;

[0013] The punching head is driven by a cylinder and is located on the upper part of the bridge.

[0024] The following, in conjunction with the accompanying drawings, further details the structure and operating principle of the welded platform for the sound barrier frame steel provided by the present invention. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0025] In the description of the present invention, unless otherwise specified, the terms "front / rear", "horizontal / vertical", etc. indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0026] It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "provided with" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model.

[0027] like Figure 1 As shown, the welding platform structure of the sound barrier frame steel includes a frame 2 with multiple guide vertical plates 1. The guide vertical plates 1 are arranged linearly, and the through hole in the center forms a track a for the steel to pass through. A welding mechanism 3 is set at the end of the track a. The welding mechanism 3 includes a bracket 31 spanning the track a and a welding head 32 set in the bracket 31. The through hole of the guide vertical plate 1 is connected to a swivel 12 driven by a motor 11 through a bearing, or a swivel driven by a motor is set in the bracket 31 of the welding mechanism 3, so as to realize the mutual rotation of the welding head 32 and the steel in the track a.

[0028] Its working principle is as follows: a plurality of linearly arranged guide vertical plates 1 are provided on the frame 2 of the welding platform, and the central through hole forms a track a for the steel section to pass through. The end of the track a, that is, the welding point of the steel section end, is installed with a welding mechanism 3 through a bracket 31, and its welding head 32 corresponds to the end of the steel section. Since the through hole of the guide vertical plate 1 is connected to the swivel 12 driven by the motor 11 through a bearing, the track a is the center of the swivel 12, so that the steel section is synchronously rotated with the swivel 12 in the track a, and the welding head 32 completes the automatic welding process. Equivalently, a swivel driven by a motor can also be set in the bracket 31 of the welding mechanism 3, and the welding head 32 is installed on the swivel, which also achieves the effect of mutual rotation between the welding head 32 and the steel section in the track a.

[0029] It should be noted that the welding is performed by the rotating ring welding head 32, and the weld is circular. Therefore, for the H-shaped steel, an annular connecting plate needs to be pre-welded at its end. The annular connecting plate can be welded to the end of the H-shaped steel first on this welding platform, and then the annular connecting plate can be welded to the base plate and the stiffening plate to adapt to the welding method in which the welding head 32 and the end of the steel rotate with each other.

[0030] In the welded platform structure constituting the above-mentioned sound barrier frame steel,

[0031] --like Figure 2 As shown, the connection between the rotating ring 12 and the motor 11 is a synchronous belt 13, which is wrapped around the outer side of the rotating ring 12 and the drive shaft of the motor 11. That is, the motor 11 realizes the rotation of the rotating ring 12 through the synchronous belt 13, achieving the effect of circumferential welding of the welding head 32;

[0032] For H-beams, the track a includes two pairs of rollers 4 arranged in a rotating ring 12. The rollers 4 are vertically distributed. One pair of rollers clamps the outer sides of the side plates of the H-beam, and the other pair of rollers clamps the two sides of the web, thereby positioning the H-beam and ensuring a smooth rotation welding process.

[0033] In order to automatically feed the H-beam in the track a, at least one set of rollers 4 includes an active roller driven by a servo motor, which drives the H-beam to move along the track a, thereby enhancing the continuity of the welding operation;

[0034] ——Furthermore, the surface of the rotating ring 12 is provided with vertical and horizontal grooves 51, and the support plates 52 of the rollers 4 are respectively placed in the grooves 51. The support plates 52 are provided with sliding grooves 53, and the limiting pins 54 are installed in the sliding grooves 53 to achieve the positioning of the support plates 52 and the grooves 51. The stability of the rollers 4 is improved by the support plates 52. The positioning pins 54 in the sliding grooves 53 of the support plates 52 achieve the relative position change of the rollers 4 along the direction of the grooves 51, adapting to the specifications of H-shaped steels of different sizes and ensuring stable and secure clamping;

[0035] --like Figure 3 As shown, preferably, a cutting mechanism 6 is provided at the front of the inner track a of the frame 2, and a bridge 61 of the cutting mechanism 6 is placed between two adjacent guide vertical plates 1, that is, the front end of the inner track a of the frame 2 is extended, and the H-shaped steel is cut to a fixed length by the cutting mechanism 6. The bridge 61 spans the track a, and a punching head 62 and a cutting saw blade 63 are provided inside the bridge 61 to realize functions such as punching process holes and fixed-length cutting.

[0036] Furthermore, the punching head 62 is driven by a pneumatic cylinder and is located on the upper portion of the bridge 61. The cutting saw blades 63 are driven by a motor and are symmetrically arranged in frames 64 on both sides of the bridge 61. A transverse guide rail 65 is provided between the opposing frames 64. The support shaft of the cutting saw blade 63 is provided in the transverse guide rail 65. That is, the cutting saw blades 63 on both sides of the bridge 61 move relative to each other through the transverse guide rail 65 to complete the cutting and truncation.

[0037] To enhance intelligent control, a detection head 71 is provided behind the aforementioned cutoff mechanism 6. The detection head 71 is mounted on the side of track a and is used to measure the length of the section steel extending beyond the cutoff mechanism 6. This ensures that the section steel within track a is cut to a predetermined length by detecting the end of the section steel. The predetermined length is the distance between the rear end of the cutoff mechanism 6 and the detection head 71. The cutoff mechanism 6 and the detection head 71 are both electrically connected to a controller 72. When the end of the section steel reaches the detection head 71, the detection head 71 sends a feedback signal to the controller, which then sends a cutoff instruction to the cutoff mechanism 6.

[0038] The above-mentioned detection head 71 can be replaced by a laser rangefinder or a reflector. A laser rangefinder is set at the cutting mechanism 6, and a reflector is set at the welding mechanism 3 or the pre-set length position of the steel section. The electrical connection also includes other necessary sensors, solenoid valve groups, power lines and communication lines, etc., which are added according to actual application conditions. The above-mentioned controller can also be electrically connected to the welding mechanism 3 to realize automatic control of the entire equipment.

[0039] --like Figure 4 As shown, preferably, a grinding unit is provided in the bracket 31 of the welding mechanism 3, and the grinding unit includes a guide rail 33 installed on the side of the bracket 31 and a grinding head 35 provided inside the guide rail 33. The guide rail 33 is preferably arranged vertically. The grinding head 35 includes components such as milling tools and grinding wheels to complete processes such as beveling and edge grinding of the end of the steel section. The welding head 32 is placed in the guide rail at the upper part of the bracket 31. The guide rail is preferably arranged vertically and can also be replaced by a cylinder 35. That is, the welding head 32 can be radially extended and retracted along the track a to adapt to steel sections of different shapes, so that the weld is closer to the cross-sectional profile of the steel section, ensuring a reliable welding connection.

[0040] ——As a preferred implementation method, Figure 5 As shown, a feeding mechanism 8 is provided at the front end of the frame 2. The feeding mechanism 8 includes a steel storage rack 82 and a roller conveyor 83 connected by a cylinder assembly 81 or a manipulator. The roller conveyor 83 corresponds to the track a in the frame 2. That is, the steel in the storage rack 82 is pushed out by the cylinder assembly 81. After reaching the roller conveyor 83, the steel automatically enters the track a of the welding platform.

[0041] Preferably, the above-mentioned steel storage rack 82 adopts a double-layer structure, the upper rack body can store the profiles, the lower rack body is flush with the roller conveyor 83, guide rails are set on both sides of the upper rack body, and a manipulator (pneumatic gripper) is set in the guide rail to clamp the profiles and move them into the lower rack body. The cylinder assembly 81 is set in the lower rack body to further push the profiles into the roller conveyor 83;

[0042] In order to increase the storage and transportation capacity, the upper and lower shelves adopt a drawer-type combination structure, and the two can move relative to each other through side tracks (grooves and slides).

[0043] ——Furthermore, a feeding mechanism 9 is provided at the rear end of the above-mentioned frame 2. The feeding mechanism 9 includes a welding accessory rack 92 and a positioning track connected by a cylinder assembly or a manipulator 91. The welding accessories include a welding base plate b or a stiffening plate c. The positioning track is provided on the side of the bracket 31 of the welding mechanism 3, corresponding to its welding head 32. Automatic auxiliary welding is achieved through the feeding mechanism 9. The manipulator 91 is preferably a multi-axis manipulator to achieve functions such as accessory clamping, transmission, and positioning;

[0044] In this embodiment, the cross-section of the frame 2 is H-shaped, that is, a groove 101 is provided on the upper surface, and a conveyor belt 102 can be laid in the groove 101, so that the welding waste can be discharged from the welding platform in time. The lower part of the rear end of the frame 2 is used to uniformly recycle the waste through the transfer platform 10, and the upper part of the rear end of the frame 2 is used to transport the welded steel frame structure through the discharge platform 10'. A pulley 103 and a support leg 104 are installed at the bottom of the frame 2 to facilitate the overall movement and positioning of the welding platform.

[0045] The above-described embodiments are only used to illustrate the technical solution of the present invention and are not limiting conditions for the implementation of the present invention.
