Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guardrail installation, in particular to a guardrail welding platform. Background Art
[0002] Welded slope guardrail is a common traffic safety facility, mainly used for the protection of inclined ground such as slopes and stairs. Its main function is to prevent people or vehicles from falling, and it can also beautify the environment.
[0003] Most of the slope guardrails are welded manually. When welding, it is necessary to manually cut the required bevel angles of two horizontal bars and multiple vertical bars, and then place them for welding. During welding, it is inconvenient to fix the horizontal bars and vertical bars. It is easy to cause the horizontal bars and vertical bars to shift during welding, resulting in poor quality of the welded guardrail. In addition, different slopes require different bevel angles. During welding, it takes a long time to place the horizontal bars first. If the position of the horizontal bars is not placed properly, the vertical bars at both ends and in the middle will be welded incorrectly, which will cause the entire guardrail to be scrapped. In addition, for guardrails of different styles, the distance between the two horizontal bars and the length of the vertical bars are different, and continuous adjustment is required during welding. Therefore, a guardrail welding table is proposed to solve the above problems. Utility Model Content

[0021] like Figure 1-4As shown, a guardrail welding platform proposed by the utility model includes a platform 1, a mounting frame 2 and a clamp 5, the mounting frame 2 is arranged at the bottom end of the platform 1, a clamping platform 3 is arranged above the platform 1, a placement groove is opened inside the clamping platform 3, the clamp 5 is arranged in the placement groove, a first driving component 7 is arranged on the clamping platform 3, and drives the clamp 5 to move, a second driving component 4 that drives the clamping platform 3 to rotate is arranged inside the mounting frame 2, a feed port is opened at the top of the platform 1, a collecting hopper 9 is arranged at the bottom end of the platform 1, and is connected with the feed port, and two cleaning brushes 6 are slidably arranged above the platform 1.
[0022] In an optional embodiment, two groups of clamps 5 and placement slots are provided, and the two groups of clamps 5 are arranged opposite to each other. A single group of clamps 5 includes a first clamping plate 51 and a second clamping plate 52, and the first clamping plate 51 and the second clamping plate 52 are arranged opposite to each other.
[0023] In the utility model, four supporting legs are arranged at the bottom end of the frame 1 for supporting the frame 1, the mounting frame 2 is arranged at the bottom end of the frame 1, the second driving assembly 4 is arranged inside the mounting frame 2, and a distance is arranged between the clamping platform 3 and the frame 1 above and below, so that the cross bars of the two guardrails are respectively placed in the two placement grooves, and the two first clamps 51 are driven to move relative to each other by using the first driving assembly 7, so that the two second clamps 52 move back to back, so that the left clamp 5 clamps a cross bar, and the right clamp also clamps a cross bar, so that the two cross bars are placed in parallel, and then the second driving assembly 4 is used to rotate it to a certain angle. After the rotation, the two cross bars are still parallel, and the spacing between the two cross bars is adjusted again according to the length of the vertical bar by using the first driving assembly 7. After fixing, the vertical bar is added and welded to it, which facilitates the installation of the vertical bar and prevents the need to cut the upper and lower cross bars when installing guardrails on some slopes. After being placed in an inclined state at a certain angle, it is inconvenient to fix it, and it is inconvenient to move the distance between the two after tilting, and it is inconvenient to weld the vertical rod in the middle. Because when installing the guardrail on the slope, the vertical rod needs to always remain in a vertical state, so it is necessary to cut an angle on the horizontal rod and the vertical rod. When the two horizontal rods are rotated to the required bevel angle, cut along the X-axis, and then adjust the spacing suitable for welding with the vertical rods. The two horizontal rods thus placed, the two inclined surfaces are always in the same plane and parallel to the X-axis. The vertical rods placed parallel to the X-axis are welded to the two horizontal rods, and welding is more convenient, because generally the guardrail is two horizontal rods and multiple vertical rods. After welding two or three vertical rods on one side, it can be finalized, which can be more convenient for subsequent welding. The two collecting hoppers 9 are located on the left and right sides of the platform 1, and the bottom end of the collecting hopper 9 is inclined, which is convenient for collecting garbage on the table from the feed inlet, such as metal dust.
[0024] In an optional embodiment, the first driving assembly 7 includes a fixed frame 71, a first motor 72, a first bidirectional screw rod 73, two movable plates 74 and two threaded rods 75. The fixed frame 71 is arranged at the top of the clamping table 3, and the first motor 72 is arranged on the left side of the fixed frame 71. One end of the first bidirectional screw rod 73 is coaxially connected to the output shaft of the first motor 72, and the other end is rotatably connected to the right side wall of the fixed frame 71. The two movable plates 74 are threadedly connected to the first bidirectional screw rod 73, and the bottom ends are respectively connected to the two second clamping plates 52. The two threaded rods 75 are respectively arranged on the left and right sides of the clamping table 3, and are respectively rotatably connected to the two first clamping plates 51.
[0025] It should be noted that by starting the first driving component 7, the two first clamps 51 can be moved relative to each other, and the two second clamps 52 can be moved back to back, so as to be adjusted according to the required distance between the two cross bars. After the adjustment, they are fixed. Since the placement groove is hexagonal in shape, and the first clamp 51 and the second clamp 52 are triangular, they are just matched with the size of the placement groove, and can fix square tubes and round tubes.
[0026] In an optional embodiment, the second drive assembly 4 includes a second motor 41, a worm 42, a rotating column 43 and a worm wheel 44. The second motor 41 is arranged on the right side of the mounting frame 2. One end of the worm 42 is coaxially connected to the output shaft of the second motor 41, and the other end is rotatably connected to the left side wall of the mounting frame 2. The rotating column 43 is rotatably connected to the bottom wall of the mounting frame 2 and extends to the top of the stand 1. The clamping table 3 is arranged at the top of the rotating column 43. The worm wheel 44 is coaxially sleeved on the rotating column 43 and meshed with the worm 42.
[0027] In an optional embodiment, an angle ruler 10 is provided on the top of the stand 1 , and a pointer 11 is provided on the rotating column 43 .
[0028] It should be noted that starting the second motor 41 drives the worm 42 to rotate, and by meshing with the worm wheel 44, drives the rotating column 43 to rotate. The rotating column 43 drives the pointer 11 and the clamping platform 3 to rotate while rotating. The degree of rotation can be seen by looking at the angle ruler 10.
[0029] In an optional embodiment, a third driving assembly 8 for driving the two cleaning brushes 6 to move relative to each other is provided at the bottom end of the platform 1. The third driving assembly 8 includes a bottom frame 81, a third motor 82, a second bidirectional screw rod 83 and two connecting plates 84. The bottom frame 81 is connected to the bottom end of the platform 1, and the third motor 82 is arranged on the rear side of the bottom frame 81. One end of the second bidirectional screw rod 83 is coaxially connected to the output shaft of the third motor 82, and the other end is rotatably connected to the front side wall of the bottom frame 81. The two connecting plates 84 are threadedly connected to the second bidirectional screw rod 83 and are respectively connected to the two cleaning brushes 6.
[0030] It should be noted that by starting the third motor 82 to drive the second bidirectional screw 83 to rotate, the two connecting plates 84 move relative to or away from each other, driving the two cleaning brushes 6 to move, and the metal debris generated during welding or installation is cleaned from the feed port into the collecting hopper 9 to clean the table top.
