Description

Technical Field

[0001] This application relates to the field of bucket screen installation, and particularly to an auxiliary bracket for in-air repair welding of a bucket screen. Background Art

[0002] In the early stage of the bucket screen, the measurement and review of 9 lifting points on the roof steel grid and the processed lifting platform have been carried out, and the on-site steel structure platform has been pre-assembled. Considering the position errors of the civil steel structure lifting points and the deformation errors of the steel structure after hoisting, only 5 out of the 9 lifting points are fixed and welded at present. After the others are hoisted by the crane, on-site debugging, docking and welding are carried out. The hoisting debugging and welding time need to be completed within one day. After the crane is unloaded and erected, an aerial work platform needs to carry out repair welding. During the repair welding process, workers need to stand in the aerial work platform and hold the welding torch by hand for operation. It is quite laborious to hold for a long time, the stability is difficult to guarantee, and the welding is prone to be crooked. Therefore, we propose an auxiliary bracket for in-air repair welding of a bucket screen, which is installed on the guardrail of the aerial work platform, can adjust the welding height and angle within a certain range, and achieve stable straight-line welding, with convenient operation and improved welding efficiency.

[0031] Combined with Figures 1 - 4 , this embodiment of the present application discloses an auxiliary bracket for in-air repair welding of a bucket screen, including a fixing plate 3 installed on an aerial work platform 1 through two clamps 2. Both sides of the bottom of the fixing plate 3 are fixedly connected with base blocks 4. A rotating shaft rod 5 is rotatably connected between the two base blocks 4. The surface of the rotating shaft rod 5 is fixedly connected with a movable plate 6. Above the movable plate 6, there is a lifting plate 7 located above the fixing plate 3. An elevating drive assembly 8 is arranged between the movable plate 6 and the lifting plate 7. A locking assembly 9 is arranged between the rotating shaft rod 5 and the left base block 4. The top of the lifting plate 7 is fixedly connected with a U-shaped frame 10. A movable seat 11 is slidably connected to the top of the lifting plate 7. Above the movable seat 11, there is a clamping assembly 12. The clamping assembly 12 includes a clamping groove 121 opened on the front side of the movable seat 11. A clamping block 123 is slidably connected to the top of the movable seat 11. The rear side of the clamping block 123 is fixedly connected with a U-shaped rod 124. The rear side of the top of the movable seat 11 is fixedly connected with a threaded sleeve block 125. A threaded rod 126 is threadedly connected to the inner cavity of the threaded sleeve block 125. The front end of the threaded rod 126 is rotatably connected to the U-shaped rod 124. Two symmetrical fixed rails 122 are fixedly connected to the top of the movable seat 11. The clamping block 123 is slidably connected to the surfaces of the two fixed rails 122. A universal ball seat 13 is fixedly installed on one side of the bottom of the movable seat 11.

[0032] Embodiment 2:

[0033] Combined with Figure 1 and Figure 2, the lifting drive assembly 8 includes a threaded post 81 fixedly connected to the bottom of the lifting plate 7. The bottom of the threaded post 81 penetrates to the bottom of the movable plate 6. A rotatable threaded sleeve 82 is installed at the bottom of the movable plate 6. The threaded sleeve 82 is threadedly connected to the surface of the threaded post 81. Four toggle rods 83 are fixedly connected in a circular array on the surface of the threaded sleeve 82. Through the arrangement of the toggle rods 83, a force application point can be provided for the user to rotate the threaded sleeve 82, which provides convenience for the user to operate the rotation of the threaded sleeve 82.

[0034] Working principle: When the utility model is in use, the user installs the fixed plate 3 on the railing of the aerial work platform 1 through the clamp 2. Then, the welding torch is inserted into the inner cavity of the clamping groove 121 from below the movable seat 11, so that the welding head is exposed above the movable seat 11. Then, the threaded rod 126 is operated to rotate. Due to the cooperation of the threaded sleeve block 125 and the thread, the threaded rod 126 moves backward and rotates, thereby driving the clamping block 123 to slide on the surface of the fixed rail 122 to clamp the welding torch. The butterfly welding torch is fixedly installed on the movable seat 11. When the aerial work platform 1 works, the guardrail is raised to a suitable height. Then, if there is an angular deviation, the user lifts the U-shaped frame 10. The U-shaped frame 10 drives the movable plate 6, the lifting plate 7 and the lifting drive assembly 8 to rotate around the rotating shaft rod 5. After the angle is adjusted appropriately, the fastening bolt on the locking assembly 9 is tightened so that the fastening bolt abuts against the surface of the rotating shaft rod 5 to limit the rotation of the rotating shaft rod 5, thereby locking the angle of the lifting plate 7 at this time. Then, the toggle rod 83 is operated to rotate the threaded sleeve 82. Due to the cooperation of the threaded post 81 and the thread, the threaded post 81 rises to make the lifting plate 7 rise, so that the welding torch on the movable seat 11 contacts the weld. By slowly pulling the pull rod 14, the pull rod 14 drives the movable seat 11 to slide on the top of the lifting plate 7 through the universal ball seat 13, and the welding torch in the working state can perform linear welding on the weld without manual lifting of the welding torch.

[0035] In summary: For this auxiliary bracket for repairing and welding in the air of the bucket screen, the fixed plate 3 is installed on the railing of the aerial work platform 1 through the clamp 2. Then, the welding torch is fixedly installed on the movable seat 11 through the clamping assembly 12. When the aerial work platform 1 works, the guardrail is raised to a suitable height. Then, if there is an angular deviation, the user lifts the U-shaped frame 10 to make the lifting plate 7 rotate around the rotating shaft rod 5. After the angle is adjusted appropriately, the rotation of the lifting plate 7 is locked and restricted by the locking assembly 9. Then, the lifting drive assembly 8 is operated to make the lifting plate 7 rise, so that the welding torch on the movable seat 11 contacts the weld. By slowly pulling the pull rod 14, the movable seat 11 slides on the top of the lifting plate 7, and the welding torch in the working state can perform linear welding on the weld. Without manual lifting of the welding torch, it can be installed on the railing of the aerial work platform, and can adjust the welding height and angle within a certain range, and achieve stable linear welding, with convenient operation and improved welding efficiency.

[0036] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
