[0022] For details, please refer to Figure 2 or Figure 3 A towing frame 14 is installed on the chassis 3; furthermore, the towing frame 14 is used for towing connection between the chassis 3 and an external transport vehicle.

[0023] For details, please refer to Figure 4 The outer wall of the guide roller 7 is covered with a soft anti-slip layer 15; furthermore, the soft anti-slip layer 15 can be a rubber layer, a silicone layer or a soft fiber layer, etc.

[0024] For details, please participate. Figure 4 It also includes a speed-regulating motor 9 and a transmission belt 10 fixedly installed on the frame 6. The output shaft of the speed-regulating motor 9 is connected to the guide roller 7 via the transmission belt 10.

[0029] The guardrail arrangement auxiliary device provided in this embodiment extends or shortens the output end of the adjustment cylinder 12 by activating the adjustment cylinder 12, thereby adaptively adjusting the tilt of the truck bed 4 so that the loading end of the truck bed 4 matches the height of the external transport vehicle, so that the operator can move the guardrail body 1 from the transport vehicle into the truck bed 4; the placement support 13 can limit the minimum tilt angle of the truck bed 4. In the non-use state, the bottom of the truck bed 4 can be directly placed on the placement support 13 without the adjustment cylinder 12 being continuously subjected to force, thus avoiding the adjustment cylinder 12 being in a working state for a long time.

[0030] The process of using the guardrail arrangement auxiliary device provided by this utility model is as follows: The traction frame 14 on the walking chassis 3 is connected to the transport vehicle equipped with guardrails. The transport vehicle drives the walking chassis 3 to move along the arrangement path of the guardrails. The operator puts the guardrail body 1 into the truck bed 4, and the mounting seat 2 enters the slide groove 5. Under the action of gravity, the guardrail body 1 slides downward in the truck bed 4. Under the action of the elastic support 8, the guardrail body 1 is elastically clamped between two adjacent guide rollers 7. The speed regulating motor 9 drives the guide rollers 7 to rotate, so that the guardrail body 1 is vertical and slides down slowly in the truck bed 4. After the guardrail body 1 slides out of the truck bed 4, it falls vertically to the ground to be installed. In this way, the continuous arrangement and installation of multiple guardrail bodies 1 can be achieved.
