2．台车及台车牵引机构2.1台车由车架、台车炉衬砌体、台车牵引机构等组

2. Trolley and trolley traction mechanism <br>2.1 The trolley is composed of frame, trolley furnace lining body, trolley traction mechanism and so on. <br>2.2 The frame of the trolley is made of 18# channel steel. The thickness of the side plate of the trolley is 10mm, and the thickness of the bottom plate is 6mm. Both are welded with Q235 steel plates. The structure of the trolley is strong and not easy to deform and warp, and its strength can fully meet the specified loading capacity. . "2.3 The traveling mechanism of the trolley adopts the wheel type self-propelled mode. Four pairs of traveling wheels are installed under the trolley body, and a gear reducer is installed <br>in the head box of the trolley. The walking power is transmitted to the active movement of the trolley through the sprocket and chain. 2.4 Masonry of the furnace lining of <br>the trolley <br>: pave a layer of 5mm thick asbestos board on the bottom of the car body, and then use diatomite bricks and heavy bricks to pave two layers. The middle layer is made of (NG- 1.3) One layer of straight bricks is laid flat, and the refractory layer is built with heavy bricks. When the refractory layer is built, a high-temperature binder is added to the mud to reconcile it to improve the structural strength, and the load-bearing plane of the refractory layer remains flat. <br>2.5 There are safety limit switches at both ends of the trolley stroke to avoid damage to the furnace body and accidents caused by over-travel travel.

Trolley and trolley traction mechanism<br>2.1 The trolley is composed of a frame, trolley furnace lining masonry, trolley traction mechanism, etc.<br>2.2 The frame of the trolley is made of 18 # channel steel, and the thickness of the side plate and bottom plate of the trolley is 10mm and 6mm, both of which are welded with Q235 steel plates. This structure of the trolley is sturdy and not easy to deform and warp, and its strength can fully meet the specified loading capacity.<br>2.3 The trolley traveling mechanism adopts a wheeled self-propelled mode, with 4 pairs of walking wheels installed below the trolley body in the front box of the trolley<br>Equipped with a gear reducer, the traveling power is transmitted to the active wheels of the trolley through sprockets and chains, driving the trolley to move. "<br>2.4 Masonry of the trolley furnace lining: A layer of 5mm thick asbestos board is laid flat at the bottom of the vehicle body, and then mixed with diatomaceous earth bricks and heavy bricks to lay two layers. The middle layer is laid with (NG-1.3) straight bricks, and the refractory layer is laid with heavy bricks. During the masonry of the refractory layer bricks, high-temperature binder is added to the mud to improve structural strength, and the load-bearing plane of the refractory layer is kept flat.<br>A safety limit switch is installed at both ends of the travel limit of the 2.5 trolley to prevent damage to the furnace body and accidents caused by exceeding the travel limit.
