Two groups of the leg arms 9 located at the front or rear of the trolley body 1 are symmetrically arranged along the center line of the width direction of the trolley body 1. The axis of the hinging of the leg arm 9 with the corner end of the trolley body 1 is consistent with the length direction of the trolley body 1, the leg arm 9 rotates in the vertical plane along the width direction of the trolley body 1.

[0031] Example 1

[0032] As shown in Figures 1-3 When transporting a material (steel beam) with a length of less than 5m, a single transport trolley is enabled. The operator controls the trolley to walk to the position to be transported, starts the support leg hydraulic cylinder 8, and synchronously expands the support leg arms 9 at the four corners of the vehicle body 1 to the horizontal state. At this time, the support leg roller 10 contacts the ground to form auxiliary support. The lateral telescopic inner arm 4 is extended outward under the drive of the hydraulic cylinder, the vertical lifting arm 5 is lowered, and the lifting plate 6 clamps the middle part of the steel beam through the lifting clamp. After the steel beam is lifted by the lifting hydraulic cylinder, the operator controls the walking drive mechanism 7 to move the bottom wheel 2 along the length direction of the vehicle body. When lateral adjustment is needed, the left and right groups of lateral telescopic mechanisms can be telescoped to realize lateral movement of the material.

[0033] Example 2

[0034] As shown in Figure 4As shown, when transporting 12m of material (concrete beam or D-shaped temporary beam), two trolleys work together. The operator maneuvers the trolley to the desired transfer position, activates the outrigger hydraulic cylinders 8, and simultaneously extends the outrigger arms 9 at the four corners of the trolley body 1 to a horizontal position. At this time, the outrigger rollers 10 contact the ground to provide auxiliary support. The lateral telescopic inner arm 4 extends outward under the drive of the hydraulic cylinder, the vertical lifting arm 5 descends, and the lifting plate 6 clamps one end of the concrete beam through the lifting clamps. After the lifting hydraulic cylinder raises the steel beam, the operator controls the walking drive mechanism 7 to move the bottom wheels 2 along the length of the trolley body. The control system simultaneously activates the walking drive mechanisms of both trolleys to keep the bottom wheels moving at the same speed. When lateral adjustment is required, the left and right sets of lateral telescopic mechanisms can extend and retract to achieve lateral movement of the material.

[0035] In Examples 1 and 2, when the vehicle body of the transport trolley also needs to move laterally, the outrigger arms are controlled to rotate downward by the outrigger hydraulic cylinders, thereby raising the entire vehicle body and lifting the bottom wheels away from the ground. Then, the outrigger rollers are driven by the motor to move synchronously, thus moving the vehicle body laterally.

[0036] Example 3

[0037] like Figure 4 As shown, construction section 16 represents the structures on both sides of the bridge closure point. The bridge closure construction is divided into two sections. Assuming the first construction section on the left is adjacent to a cliff or water area and can only accommodate a single trolley, the second construction section uses a double-trolley system. The outrigger hydraulic cylinders 8 are activated, simultaneously extending the outrigger arms 9 at the four corners of the trolley body 1 to a horizontal position. When the distance between the trolleys in the two construction sections at the closure point is 2 meters, the roller drive system is activated. The second section's double transport trolley conveying drive mechanism 11 rotates, driving the rollers to transport materials. The first section's transport trolley rollers respond at the same speed. This transfers the materials from the second construction section to the first construction section.
