Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, and particularly relates to a sliding wire device for a welding electric machine of a steel bar framework in a precast beam yard. Background Art

[0002] China's highway bridges have currently entered a period of rapid development. Most of the beam slabs of bridges are precast in the beam yard and transported and erected onto the bridge piers by a beam transporter and a bridge erecting machine. During the precasting process of the beam slabs, the sides of the steel bar frameworks mostly need to be welded together. The working principle of a welding electric machine is to reduce the voltage of the commonly used 220V voltage or 380V industrial electricity through a voltage reducer in the welding electric machine, enhance the current, and use the huge heat generated by the electric energy to melt the steel. The incorporation of the welding rod makes the fusion between the steels higher.

[0003] At present, most of the precast beam slabs are 30m or 40m. Usually, the wires of the welding electric machine are directly placed on the ground and are dragged roughly when changing positions. Moreover, vehicles often pass back and forth on the road, which will cause varying degrees of damage to the wires, and even cause damage due to excessive current, greatly reducing the service life of the welding electric machine and posing a certain safety risk.

The I-shaped cross brace is perpendicular to the two concave bearing plates. The bottom of the I-shaped cross brace is connected to a lower bearing plate. An opening rubber gasket is clamped between the bottom of the I-shaped cross brace and the lower bearing plate; a plurality of through holes for facilitating the sliding wire to pass through are opened on the opening rubber gasket.

[0008] Preferably, the two concave pulleys are arranged on the bottom plate of the sliding track and can slide along the bottom plate of the sliding track.

[0009] Preferably, the socket bolts are installed on the concave socket below the sliding track.

[0010] Preferably, through slots are formed at the top and bottom of the I-shaped cross brace. The upper through bolt and the lower through bolt are respectively slidably connected in the through slots. The other end of the upper through bolt is connected to the bottom of the concave socket, and the other end of the lower through bolt is connected to the top of the lower socket.
