[0015] Referring to Figures 1-4 , this embodiment is a kind of with telescopic track's towing machine, including car frame 1, car frame 1 bottom is equipped with wheel, one of which is connected with drive mechanism 2, car frame 1 top is equipped with two slide rails, two slide rails are equipped with slide support 6, and one end of slide rail is equipped with linear drive mechanism 2, linear drive mechanism 2 is connected with slide support 6, and the front end of slide support 6 exceeds the front end of car frame 1 and is equipped with downwardly extending support rod 10, and support rod 10 bottom is equipped with gyro wheel 11;The slide support 6 is provided with towing car track 4 along the length direction, and the towing car track 4 is equipped with towing trolley 7, and the towing trolley 7 is used to tow kiln car, and the outer side of towing car track 4 is equipped with kiln car track 3.

[0016] Further, the towing trolley 7 includes a vehicle body, a driving motor is arranged in the vehicle body, a front hook and a rear hook are arranged at the top end of the vehicle body, the front hook and the rear hook are rotatably connected with the vehicle body respectively, a trapezoidal slide block is arranged below the front hook and the rear hook, and a cylinder is connected to one end of the trapezoidal slide block. The cylinder pushes and pulls the trapezoidal slide block, so that the front hook and the rear hook are in an upwardly turned state at the same time. When the kiln car needs to be pulled backward, the front hook is vertically raised, and when the kiln car needs to be pushed forward, the rear hook is vertically raised.

[0017] Further, the output end of the driving motor is provided with a gear 8, and a straight rack 9 is arranged on the slide support 6 along the length direction, and the straight rack 9 is engaged with the gear 8.

[0018] Further, the straight line driving mechanism 2 adopts an oil cylinder 5, the cylinder body of the oil cylinder 5 is connected with the vehicle frame 1, and the piston rod of the oil cylinder 5 is hinged with the sliding support 6.
