[0028] When the installation box 8 is adjusted according to the installation of the larger and heavier cement pipe, the connecting rod 6 moves backward, the synchronous belt rack 117 moves backward, the toothed disc 116 and the rotating drum 114 rotate in the installation block 115, the screw rod 113 moves to the left in the rotating drum 114, and the counterweight box 112 is adjusted to the corresponding position to the left in the sliding groove 111. Through the corresponding adjustment of the position of the counterweight box 112, the weight corresponding to the direction of the steering wheel group 2 operated by the personnel is increased when the larger specification cement pipe is loaded and transferred, which prevents the base frame 1 from being unbalanced due to the loaded cement pipe, causes the steering wheel group 2 operated by the personnel to appear to be tilted in the direction, and reduces the risk of injury to the operator. Example two

[0029] On the basis of example one, please refer to Figures 1 to 8 A damping assembly 12 is arranged between the fixed block 9 and the base frame 1, the damping assembly 12 includes a sliding bar 121, the sliding bar 121 is slidingly installed in the middle segment of the inside of the installation box 8, the top of the sliding bar 121 is connected to the bottom of the fixed block 9 through a plurality of springs, a sliding bar 122 is arranged below the sliding bar 121, the sliding bar 122 is vertically limited and slidingly arranged in the lower segment of the inside of the installation box 8, magnetic plates are designed on the adjacent surfaces of the sliding bar 121 and the sliding bar 122, the magnetic plates on the adjacent surfaces of the sliding bar 121 and the sliding bar 122 have the same magnetic pole, a top block 123 is fixed to the bottom of the sliding bar 122, an adjusting plate 124 is slidingly connected to the top block 123, the adjusting plate 124 is installed on the inside horizontal plate of the base frame 1, the top surface of the adjusting plate 124 is designed as an inclined surface structure, the direction of the inclined surface of the top surface of the adjusting plate 124 is opposite to the direction of the arc-shaped curved surface of the fixed block 9, and the damping assembly 12 is used for buffering the sliding of the fixed block 9;

[0030] When the installation box 8 on the left and right sides is adjusted to the opposite sliding position in the sliding groove plate 10 during the adjustment process of the installation box 8 according to the larger and heavier cement pipe, the sliding bar 122 and the top block 123 are slidingly contacted on the adjusting plate 124 from high to low, so that the sliding bar 122 is slidingly adjusted to the corresponding position in the installation box 8, at this time, the sliding bar 121 is slidingly adjusted downward in the installation box 8 due to the reduction of repulsion caused by the downward movement of the sliding bar 122, and the elasticity between the sliding bar 121 and the fixed block 9 is correspondingly adjusted, so that the damping and buffering amplitude is correspondingly adjusted during the rotation of the cement pipe of different larger specifications, the damage of the cement pipe caused by the too hard or too soft damping and buffering effect is reduced, and the damping and buffering effect is further improved through the corresponding resistance of the spring and the repulsion between the sliding bar 121 and the sliding bar 122.

[0031] Working principle: in the process of using the multifunctional trolley for transporting cement pipes, when transporting large-diameter and heavy cement pipes, the operator first manually rotates the screw rod one 5 according to the diameter of the transported cement pipe, so that the connecting rod one 6 drives the installation box 8 to slide backward in the sliding groove plate 10, while the connecting rod two 7 drives the installation box 8 to slide forward in the sliding groove plate 10, and the left and right staggered installation boxes 8 move in opposite directions, and are adjusted to the appropriate position according to the specification of the transported cement pipe. Then, through the hoisting equipment, the cement pipe is hoisted onto the fixed block 9, and then the screw rod one 5 is reversed to move the two fixed blocks 9 in opposite directions, and the cement pipe on the fixed block 9 is fixed and limited;

[0032] In the above process, when the installation box 8 is adjusted according to the large-diameter and heavy cement pipe, the connecting rod one 6 moves backward, the synchronous belt gear 117 moves backward, the gear disc 116 and the rotating cylinder 114 rotate in the mounting block 115, the screw rod two 113 moves to the left in the rotating cylinder 114, and the counterweight box 112 adjusts to the corresponding position in the sliding groove one 111. Through the corresponding adjustment of the position of the counterweight box 112, when the large-diameter cement pipe is loaded and transported, the weight of the steering wheel group 2 operated by the operator is correspondingly increased, preventing the base frame 1 from being unbalanced due to the loaded cement pipe, causing the steering wheel group 2 operated by the operator to tilt, and reducing the risk of injury to the operator;

[0033] At the same time, in the above process, when the installation box 8 is adjusted according to the large-diameter and heavy cement pipe, the left and right staggered installation boxes 8 slide in opposite directions in the sliding groove plate 10 to adjust the position, which simultaneously drives the sliding bar two 122 and the top block 123 to slide from high to low on the adjusting plate 124, so that the sliding bar two 122 slides downward in the installation box 8 to adjust the corresponding position. At this time, the sliding bar one 121 slides downward in the installation box 8 due to the decrease of repulsion caused by the downward movement of the sliding bar two 122, and correspondingly adjusts the elasticity between the spring above the sliding bar one 121 and the fixed block 9, thereby correspondingly adjusting the shock absorption amplitude during the transportation of different large-diameter cement pipes, reducing the damage to the cement pipe caused by excessive hardness or softness of the shock absorption effect, and further buffering through the corresponding resistance of the spring and the repulsion between the sliding bar one 121 and the sliding bar two 122 to optimize the shock absorption effect.
