The movement of the inclined rod 24 causes the slider 22 to move, which in turn pushes the first spring 23 to move. Due to the presence of the first spring piece 62 and the second spring piece 63, the first spring 23 deforms, causing the first spring piece 62 and the second spring piece 63 to deform as well. The first spring 23, the second spring 53, the first spring piece 62, and the second spring piece 63 can buffer the pressure on the coke can body 11, thereby improving the service life of the transport vehicle body 1 and allowing for its maintenance. When the motor 43 starts, it can drive the double-headed screw 36 and gear 41 on the front to rotate. Through the toothed belt 42, it can drive the gear 41 and double-headed screw 36 on the back to rotate. The rotation of the two double-headed screws 36 can drive the two moving blocks 32 on the front and rear sides to move towards the middle, which in turn can drive the moving rod 33 to move. The movement of the moving rod 33 can drive the positioning seat 34 to move, thereby quickly positioning and locking the coke tank body 11, which can prevent the coke tank body 11 from shifting when the transport vehicle body 1 moves. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.
