DETAILED DESCRIPTION

[0018] The following will be combined with the Figures 1-4 The specific embodiment of the utility model is further explained in detail.

[0019] The utility model discloses a lifting device 2 can drive connecting rod 7 along the vertical movement, and then make the air duct 9, gas detector 15 and other related components synchronous along the vertical movement, and then can be positioned in the height of gas detector 15 suitable for multiple gas pipeline detection, after controlling electric board car 1 along the gas pipeline movement and carries out the inspection operation, relative to the traditional manual gas detector 15 detection, not only liberates the manpower, but also greatly improves the detection efficiency.

[0020] In the embodiment two, the height of the gas detector 15 is adjusted by the lifting device 2, and the gas detector 15 is positioned at the height suitable for detection, specifically: the screw rod 5 connected between the support beam 4 and the electric board car 1 is rotated clockwise, a turntable 17 is arranged on the upper end of the screw rod 5 for facilitating the rotation of the screw rod 5, the screw rod 5 is rotated clockwise to drive the lifting rod 6 through the screw sleeve 18, the lifting rod 6 is vertically slidably connected with the vertical rod 3 through the sliding sleeve 19, and therefore the screw rod 5 is rotated clockwise to drive the lifting rod 6 to move upward along the vertical rod 3, and the screw rod 5 is correspondingly rotated counterclockwise to drive the lifting rod 6 to move downward along the vertical rod 3; the lifting rod 6 moves along the vertical rod 3 to drive the air duct 9, the gas detector 15 and other related components to move along the vertical rod 3 through the connecting rod 7 and the clamp 8. According to the height of the pipeline, the height of the detector is positioned at the height suitable for detection, then the position of the electric board car 1 is adjusted, the horizontal distance between the detector and the gas pipeline is also suitable for detection, then the electric board car 1 and the gas detector 15 are started, and the electric board car 1 is controlled to move along the gas pipeline for inspection.
