Detailed Description

In order to explain the utility model more fully, the utility model provides an implementation example. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.

The utility model discloses in the interior outer left and right directions, be inside to the centre in figure 2, outside to both sides.

The invention is explained in further detail with reference to the drawings, in which the reference symbols refer to: 1: a frame; 2: a foot pedal; 3: a shaft; 4: a wire rope; 5: a fixed pulley; 6: counterweight, 7: a drive arm; 8: a pull rod; 9: a swing arm shaft; 10: a swing arm A;11: a swing arm B;12: a bearing seat; 13: a slide base; 14: a stopper; 15: a limiting plate; 16: a connecting rod.

This device is installed in the planer-type frame before the operation of welding net machine threading, as shown in the attached drawing, a welding net machine threading safety device, which comprises a frame 1, install running-board 2 in threading process back below, the workman stands on the running-board during threading, the running-board rear end is installed subaerial through axle 2 rotation, front end at the running-board is connected with wire rope, rotate in the frame and install two fixed pulleys 5, wire rope 4 has counter weight 6 from the last back end connection that walks around of fixed pulley 5, fixed mounting has limiting plate 15 in the frame, when nobody was gone up on the running-board, counter weight 6 upwards draws the front end of running-board to make the running-board top under the limiting plate.
