Embodiment 1

[0023] Such as figure 1 As shown, the portable auxiliary support frame welding fixture suitable for angle steel tower installation includes a base 1, a guide groove 2 is arranged on the base 1, a fixed support plate 3 is arranged at one end of the guide groove 2, and the guide groove 2 is far away from the fixed support plate 3. One end is provided with a mobile support plate 4, a moving part 5 is provided below the mobile support plate 4, a screw rod 6 is provided through the mobile part 5, the moving part 5 and the screw rod 6 are located in the guide groove 2, and the moving part 5 and the screw rod 6 are screwed together, When the screw rod 6 rotates, the moving part 5 can move along the screw rod 6 in the guide groove 2; Move, move the moving part 5 to a suitable position in the direction of the fixed support plate 3; the fixed support plate 3 and the mobile support plate 4 are hinged with a rotating support plate 7, and the rotating support plate 7 is adjusted by the rot...

Embodiment 2

[0026] This embodiment is based on Embodiment 1 to further illustrate the present invention.

[0027] Such as figure 2 As shown, the portable auxiliary support frame welding fixture suitable for angle steel tower installation, the moving part 5 is also provided with a guide rod 8, the screw rod 6 and the guide rod 8 are parallel to each other, and the guide rod 8 plays a guiding role, so that the moving part 5 and the guide rod 8 are parallel to each other. The movement of the mobile support plate 4 is more stable, and the position of the fixed support plate 3 and the mobile support plate 4 changes greatly during welding, resulting in poor final welding quality and even the scrapping of the angle steel.

Embodiment 3

[0029] This embodiment is based on Embodiment 1 to further illustrate the present invention.

[0030] Portable auxiliary support frame welding fixture suitable for angle steel tower installation, the screw 6 is connected with a driving device (not shown in the figure), the driving device drives the screw 6 to rotate, reducing labor intensity, the driving device can choose a motor; the driving device is connected with a control A controller (not shown in the figure) controls the speed and direction of the driving device. The controller can be a common PLC controller on the market, and can realize the control of the driving device through the control method in the prior art.

Abstract

The invention discloses a portable auxiliary support frame welding fixture suitable for angle steel tower installation, comprising a base, a guide groove is arranged on the base, a fixed support plate is arranged at one end of the guide groove, and a movable support plate is arranged at the end of the guide groove away from the fixed support plate , a moving part is arranged under the moving support plate, a screw rod is arranged through the moving part, the moving part and the screw rod are located in the guide groove, the moving part is screwed with the screw rod, and the fixed support plate and the moving support plate are hinged with a rotating support plate, The angle steel is placed between the fixed support plate and the movable support plate, the screw rod is rotated to compress the fixed support plate and the movable support plate, and the angle of the rotating support plate is adjusted according to the angle of the angle steel. The invention can clamp the angle steel between the fixed support plate and the movable support plate, the angle steel is not easy to generate large vibration, and there is no large gap between the two angle steels, which ensures the welding quality, and can be used according to the angle of the angle steel Adjust the angle of the rotating support plate, and its application range is wider.

Description

technical field [0001] The invention relates to a fixing device, in particular to a welding fixture for a portable auxiliary support frame suitable for installing an angle steel tower. Background technique [0002] Iron tower refers to a high tower made of steel materials. The independent steel structures erected to bear a certain air load or communication function are collectively referred to as iron towers. The current iron towers are generally made of angle steel and steel plate parts, which are combined with bolts, but only a small amount of welded parts are used locally, such as hanging wire angle steel reinforcement plates, etc. The base plate is generally welded by electric welding. The upper parts of the tower are generally hot-dip galvanized for corrosion protection. Iron towers are usually divided into the following categories from the type of steel materials: 1. Angle steel tower: the main material and web are mainly made of angle steel. Octagonal towers, the mo...
