Description

Technical Field

[0001] This utility model relates to the field of steel grating welding technology, and in particular to a steel grating welding device that is easy to position. Background Technology

[0002] Steel grating is generally made of carbon steel with a hot-dip galvanized surface to prevent oxidation. It can also be made of stainless steel. Steel grating has properties such as ventilation, light transmission, heat dissipation, slip resistance, and explosion resistance. Steel grating is a steel product made by arranging flat steel bars at certain intervals and crossbars, and welding them together with a pressure welding machine or manually to form a grid with square grids in the middle. Steel grating is mainly used as drainage ditch covers, steel structure platform panels, and stair treads. The crossbars are generally made of twisted square steel.

[0003] The existing steel grating welding device, which is designed for easy positioning, can only move its welding gun vertically and cannot move horizontally. This makes it inconvenient to weld different positions on the steel grating, thus greatly reducing welding efficiency and limiting its practicality. Therefore, we propose a steel grating welding device that is designed for easy positioning to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a convenient positioning steel grating welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A convenient positioning steel grating welding device includes: a placement platform; a support frame fixedly installed on one side of the placement platform; a second motor fixedly installed on the inner side of the support frame; a rotating shaft fixedly connected to the output end of the second motor; two worm gear segments fixedly installed on the outer side of the rotating shaft; worm wheels meshing with the outer sides of the two worm gear segments; a second screw fixedly installed inside the two worm wheels; two first T-shaped sliders threadedly connected to the outer sides of the two second screws; a U-shaped frame fixedly installed on the top of the four first T-shaped sliders; a first screw rotatably installed inside the U-shaped frame; a sliding block threadedly connected to the outer side of the first screw; a first hydraulic cylinder fixedly installed at the bottom of the sliding block; a connecting plate fixedly connected to the output end of the first hydraulic cylinder; and a welding gun fixedly installed at the bottom of the connecting plate.

[0007] Preferably, a second hydraulic cylinder is fixedly installed at the bottom of the placement platform, and a movable plate is fixedly connected to the output end of the second hydraulic cylinder. Four second guide columns are fixedly installed at the bottom of the placement platform, and the bottoms of the four second guide columns are fixedly installed on the top of the movable plate. Four first hinge seats are fixedly installed on the top of the movable plate, and rotating rods are hinged inside the four first hinge seats. One end of each of the four rotating rods is hinged to a second hinge seat. An L-shaped movable block is fixedly installed on the top of each of the four second hinge seats. Four movable holes are opened on the top of the placement platform, and the outer sides of the four L-shaped movable blocks are slidably connected to the corresponding movable holes. Clamping plates are fixedly installed inside the four L-shaped movable blocks, and rubber pads are fixedly installed on the inner sides of the four clamping plates.

[0008] Preferably, two No. 1 arc-shaped blocks are fixedly installed on one side of the placement platform, and the outer side of the rotating shaft is rotatably installed inside the two No. 1 arc-shaped blocks. Four No. 2 arc-shaped blocks are fixedly installed on the top of the placement platform, and the outer sides of the two No. 2 screws are rotatably installed inside the corresponding No. 2 arc-shaped blocks. Two No. 1 T-shaped sliding grooves are opened on the top of the placement platform, and the bottoms of the four No. 1 T-shaped sliders are slidably connected to the corresponding No. 1 T-shaped sliding grooves.

[0009] Preferably, four support rods are fixedly installed at the bottom of the placement platform, and a No. 1 motor is fixedly installed on one side of the U-shaped frame. The output end of the No. 1 motor is fixedly connected to one end of the No. 1 screw.

[0010] Preferably, a second T-shaped groove is provided on the inner side of the top of the U-shaped frame, and a second T-shaped slider is fixedly installed on the top of the sliding block, with the top of the second T-shaped slider slidably connected to the inside of the second T-shaped groove.

[0011] Preferably, four guide posts are fixedly installed at the bottom of the sliding block, and the bottoms of the four guide posts are all fixedly installed at the top of the connecting plate.

[0012] In this utility model, a convenient positioning steel grating welding device is described. Starting a second motor drives a rotating shaft to rotate, which in turn drives a worm gear section to rotate, which in turn drives a worm wheel meshing with the worm gear section to rotate, which in turn drives a second screw to rotate. This causes a first T-shaped slider, threadedly connected to the second screw, to move along a first T-shaped groove, further moving the welding gun along the first T-shaped groove. Then, starting the first motor drives the first screw to rotate, causing the welding gun to move along the second T-shaped groove. Finally, starting the first hydraulic cylinder drives the welding gun to move vertically, allowing it to move not only vertically but also horizontally. This makes it convenient to weld different positions on the steel grating, greatly improving welding efficiency and broadening its practicality.

[0013] In this utility model, a steel grating welding device for easy positioning is described. By activating the second hydraulic cylinder, the moving plate is moved vertically, which in turn moves the first hinge seat vertically, causing the rotating rod to start rotating. This causes the second hinge seat and the L-shaped moving block to move along the moving hole, and further causes the clamping plate and the rubber pad to move along the moving hole. Thus, the four clamping plates and rubber pads fix the steel grating around its perimeter, thereby preventing the steel grating from moving during welding.

[0014] This utility model has a reasonable structural design. Through the cooperation between the No. 1 hydraulic cylinder, No. 1 motor, No. 1 screw, No. 2 motor, rotating shaft, worm gear section, worm wheel and No. 2 screw, the welding gun can not only move in the vertical direction, but also in the horizontal direction. This makes it convenient to weld different positions of the steel grating, thereby greatly improving welding efficiency and making it more practical. Attached Figure Description

[0022] In this embodiment, a second hydraulic cylinder 22 is fixedly installed at the bottom of the placement platform 1. A movable plate 23 is fixedly connected to the output end of the second hydraulic cylinder 22. Four second guide columns 31 are fixedly installed at the bottom of the placement platform 1.

Rotating rods 25 are hinged inside the four first hinge seats 24. A second hinge seat 26 is hinged to one end of each of the four rotating rods 25. An L-shaped movable block 27 is fixedly installed on the top of each of the four second hinge seats 26. Four movable holes 30 are opened on the top of the placement platform 1. The outer sides of the four L-shaped movable blocks 27 are slidably connected to the corresponding movable holes 30. Clamping plates 28 are fixedly installed inside the four L-shaped movable blocks 27. Rubber pads 29 are fixedly installed on the inner sides of the four clamping plates 28, so as to facilitate the fixation of the steel grating around the perimeter through the clamping plates 28 and the rubber pads 29.

[0023] In this embodiment, two arc-shaped blocks 20 are fixedly installed on one side of the placement platform 1. The outer side of the rotating shaft 16 is rotatably installed inside the two arc-shaped blocks 20. Four arc-shaped blocks 21 are fixedly installed on the top of the placement platform 1. The outer side of two screws 19 is rotatably installed inside the corresponding arc-shaped blocks 21. Two T-shaped grooves 2 are provided on the top of the placement platform 1. The bottom of the four T-shaped sliders 3 are slidably connected to the corresponding T-shaped grooves 2. The T-shaped grooves 2 provide guidance for the movement of the T-shaped sliders 3.

When welding is required at different locations on the steel grating, the second motor 15 is activated, causing the rotating shaft 16 to rotate, which in turn causes the worm gear section 17 to rotate. This causes the worm wheel 18, which meshes with the worm section 17, to start rotating, which in turn causes the second screw 19 to start rotating. This causes the first T-shaped slider 3, which is threadedly connected to the second screw 19, to move along the first T-shaped slide groove 2. This further causes the welding gun 10 to move along the first T-shaped slide groove 2. Then, by starting the first motor 5, the first screw 6 is driven to start rotating, causing the welding gun 10 to start moving along the second T-shaped slide groove 13. Then, by starting the first hydraulic cylinder 8, the welding gun 10 is driven to move vertically, so that the welding gun 10 can not only move vertically, but also horizontally.
