The bearing frames 4 comprise a rectangular tubular transverse support beam 41, the two ends of the transverse support beam 41 are respectively welded and fixed to the column 3, a plurality of longitudinally inclined suspension rods 42 are respectively inserted at the front and rear sides of the transverse support beam 41, and a longitudinal cross-section of the cross-beam 41 is inserted in the cross-beam 41. The lower end of the suspension rod 42 of the isosceles trapezoidal pressing plate 45 is inserted into the transverse support beam 41 and pressed against the inclined surfaces on the front and rear sides of the pressing plate 45; a vertical adjusting bolt 43 is inserted into the middle of the transverse support beam 41, and the upper end of the adjusting bolt 43 passes through the transverse support beam 41 and is screwed on the pressing plate 45. A limiting sleeve 46 is screwed and fixed on the adjusting bolt 43 between the pressing plate 45 and the transverse support beam 41, and the limiting sleeve 46 presses against the lower bottom surface of the inner side of the transverse support beam 41, and the head of the adjusting bolt 43 presses against the lower bottom surface of the outer side of the transverse support beam 41;

[0020] Vertical locking bolts 44 are respectively inserted into the transverse beams 41 on both sides of the adjusting bolt 43 . The upper ends of the locking bolts 44 are screwed onto the pressure plate 45 , and the heads of the locking bolts 44 are pressed against the lower bottom surface of the outer side of the transverse beam 41 .

[0021] The support frames 4 are evenly distributed on the columns 3 in a linear vertical direction. The front and rear sides of the lower ends of the columns 3 are respectively welded and fixed with triangular rib plates 5, which are welded and fixed to the beam frame 1. The columns 3 are reinforced based on the rib plates 5.

[0022] The wheels 2 at the lower side of the beam frame 1 include two groups of fixed wheels 21 and two groups of universal wheels 22 . The fixed wheels 21 and the universal wheels 22 are respectively distributed on the frame at the front and rear sides of the beam frame 1 .

[0023] A tendon sleeve 47 with a rectangular ring-shaped longitudinal section is fixedly sleeved on the transverse support beam 41 of the carrier frame 4, and the hanging rod 42 is inserted on the tendon sleeve 47. When the air intake pipe is hung on the hanging rod 42, the air intake pipe rests on the tendon sleeve 47, which can prevent the air intake pipe from hitting the transverse support beam 41 and causing damage.

[0024] The hanging rod 42 is made of round steel, and the upper end of the hanging rod 42 is spherical. A protective sleeve 48 is inserted into the hanging rod 42.

[0027] Working principle: The utility model is a diesel engine intake pipe transfer rack, and its technical point is mainly on the carrier frame 4. The cross beam 41 on the carrier frame 4 adopts a rectangular tube shape, which can greatly reduce the gravity of the entire transfer rack and facilitate movement; but due to the wall thickness limitation of the cross beam 41, the suspension rod 42 is screwed, and the connection strength between the suspension rod 42 and the cross beam 41 is not large, and then a pressure plate 44 is added in the cross beam 41. The height of the pressure plate 44 is limited by adjusting the bolt 43 and the locking bolt 44, so that the pressure plate 44 can cooperate with the cross beam 41 to clamp and fix the suspension rod 42; when the suspension rod 42 needs to be replaced, just loosen the locking bolt 44, and then rotate the adjusting bolt 43 to adjust the pressure plate 44 to move up, so that the suspension rod 42 can be pulled out for replacement; and multiple suspension rods 42 can be replaced at the same time;

[0028] Moreover, a protective sleeve 48 is sleeved on the suspension rod 42, and a tendon cushion sleeve 47 is sleeved on the transverse support beam 41. When the intake pipe is placed, the intake pipe can be prevented from hitting the suspension rod 42 or the tendon cushion sleeve 47, thereby preventing bumps and injuries.
