[0019] beneficial effects:

[0020] (1) The utility model adopts a connecting plate and a butt plate. When actually using the portable butt conveying device for tunnel kiln cars, multiple groups of rollers are used to move multiple groups of butt plates along the slide rail. By using the control panel, the first forward and reverse motor works. The output end of the first forward and reverse motor can drive the second bevel gear to rotate. Since the first bevel gear and the second bevel gear mesh with each other, the rotating second bevel gear can push the first bevel gear to rotate. The rotating first bevel gear can drive two groups of traveling wheels to rotate through the mounting shaft. The two groups of traveling wheels can drive the connecting plate to move left or right through the towing head. When the connecting plate moves right to a suitable position, the operator sequentially sleeved multiple groups of concave plates on the side walls of adjacent two groups of connecting screws. Then, by using the threaded cooperation between adjacent two groups of connecting screws and adjacent two groups of connecting nuts, the operator manually screws the adjacent two groups of connecting nuts onto the side walls of adjacent two groups of connecting screws in the clockwise direction. Then, multiple groups of mounting bolts are respectively passed through adjacent two groups of shaft holes. Then, by using the threaded cooperation between a group of mounting bolts on the same side and a group of mounting nuts on the same side, the operator manually screws the group of mounting nuts on the same side onto the side wall of the group of mounting bolts on the same side in the clockwise direction. After that, by using the control panel, the second forward and reverse motor works. The output end of the second forward and reverse motor can drive the lead screw to rotate. Since the lead screw and the lead screw sleeve are in threaded cooperation, the rotating lead screw can push the lead screw sleeve to move up or down.

When multiple groups of insertion posts respectively move into the interiors of multiple groups of slots, the butt work is completed. After that, the group of mounting nuts on the same side is unscrewed counterclockwise. When multiple groups of mounting bolts are separated from multiple groups of mounting nuts, multiple groups of mounting nuts can be pulled out. At this time, the towing head can pull multiple groups of kiln car bodies for conveying work. By setting the connecting plate and the butt plate, the butt work of the kiln car body can be carried out at any position on the track according to the use requirements, and at the same time, there is no need to jack up the kiln car body, which improves the practicality of the portable butt conveying device for tunnel kiln cars.

[0021] (2) The utility model adopts an inclined block. According to the above operation, by using the control panel, the first forward and reverse motor works. The output end of the first forward and reverse motor can drive the first bevel gear to rotate, the second bevel gear and the mounting shaft drive two groups of traveling wheels to rotate. The two groups of traveling wheels can drive the towing head to move left or right. When the towing head moves left, the impurities inside the slide rail can be removed by the inclined block. At the same time, by using the control panel, the pump and the refrigeration component work. The pump can pump the coolant inside the water tank into the interior of the cooling cavity through the pumping pipe and the return pipe. The coolant inside the cooling cavity can enter the interior of the water tank through the connecting pipe to form a water cycle. At the same time, the refrigeration component can cool the coolant inside the water tank.

[0039] In one embodiment, the first bevel gear 7 meshes with the second bevel gear 12, facilitating the first bevel gear 7 to drive the second bevel gear 12 to rotate.

[0040] Working principle:

[0041] When actually using the portable docking and conveying device for the tunnel kiln car, multiple sets of rollers 36 are used to move multiple sets of docking plates 15 along the slide rail 2. By using the control panel, the first forward and reverse motor 11 is made to work. The output end of the first forward and reverse motor 11 can drive the second bevel gear 12 to rotate. Since the first bevel gear 7 meshes with the second bevel gear 12, the rotating second bevel gear 12 can push the first bevel gear 7 to rotate. The rotating first bevel gear 7 can drive two sets of traveling wheels 6 to rotate through the mounting shaft 5. The two sets of traveling wheels 6 can drive the connecting plate 14 to move left or right through the towing head 3. When the connecting plate 14 moves right to a suitable position, the operator sequentially sleeved multiple sets of concave plates 25 on the side walls of adjacent two sets of connecting screws 24, and then used the adjacent two sets of connecting screws 24 and the adjacent two sets of connecting nuts 26 to be threadedly matched with each other. The operator manually screwed the adjacent two sets of connecting nuts 26 onto the side walls of the adjacent two sets of connecting screws 24 in the clockwise direction, and then passed multiple sets of mounting bolts 22 through the adjacent two sets of shaft holes 21 respectively, and then used a set of mounting bolts 22 on the same side and a set of mounting nuts 23 on the same side to be threadedly matched with each other. The operator manually screwed a set of mounting nuts 23 on the same side onto the side wall of a set of mounting bolts 22 on the same side in the clockwise direction. After that, by using the control panel, the second forward and reverse motor 19 is made to work. The output end of the second forward and reverse motor 19 can drive the lead screw 17 to rotate. Since the lead screw 17 and the lead screw sleeve 16 are threadedly matched with each other, the rotating lead screw 17 can push the lead screw sleeve to move up or down. The lead screw sleeve 16 can move multiple sets of docking plates 15 up through the connecting plate 14, multiple sets of concave plates 25 and multiple sets of mounting bolts 22. When multiple sets of inserting columns 35 are respectively moved into the multiple sets of inserting slots 34, the docking work is completed. After that, the set of mounting nuts 23 on the same side is unscrewed counterclockwise. When the multiple sets of mounting bolts 22 are separated from the multiple sets of mounting nuts 23, the multiple sets of mounting nuts 23 can be pulled out. At this time, the towing head 3 can pull multiple sets of kiln car bodies 4 for conveying work. Through the provided connecting plate 14 and docking plates 15, the docking work of the kiln car body 4 can be carried out at any position on the track according to the use requirements, and at the same time, there is no need to jack up the kiln car body 4, which improves the practicality of the portable docking and conveying device for the tunnel kiln car. At the same time, according to the above operations, by using the control panel, the first forward and reverse motor 11 is made to work. The output end of the first forward and reverse motor 11 can drive the first bevel gear 7 to rotate, the second bevel gear 12 and the mounting shaft 5 to drive two sets of traveling wheels 6 to rotate. The two sets of traveling wheels 6 can drive the towing head 3 to move left or right. When the towing head 3 moves left, the impurities inside the slide rail 2 can be removed by the inclined block 13. At the same time, by using the control panel, the pumping pump 31 and the refrigeration component are made to work. The pumping pump 31 can pump the coolant inside the water tank 27 into the inside of the cooling cavity 28 through the pumping pipe 32 and the return pipe 30. The coolant inside the cooling cavity 28 can enter the water tank 27 through the connecting pipe 29 to form a water cycle. At the same time, the refrigeration component can cool the coolant inside the water tank 27. This operation can prevent the inclined block 13 from being damaged due to the heat generated by the friction between the inclined block 13 and the slide rail 2.Through the provided inclined block 13, impurities inside the slide rail 2 can be removed, preventing the impurities inside the slide rail 2 from hindering the movement of the kiln car body 4, thus providing a guarantee for the movement and use of the kiln car body 4 of the portable docking and conveying device for tunnel kiln cars.
