When the second direction valve 31 is in the third operating state, the brake member 382 is pushed to move under the action of the brake cylinder 381, so that the brake member 382 contacts with the wheel 112, and braking is achieved. When the second directional valve 31 is in the first working state, the compressed gas in the first chamber 391 enters the first chamber of the brake cylinder 381, the compressed gas in the first chamber pushes the brake cylinder 381 to switch the position, so that the brake piece 382 is separated from the wheel 112, and the brake is unlocked, and meanwhile, the first one-way valve 383 can prevent the compressed gas entering the first chamber from flowing back, so that the brake piece 382 can be reliably kept at the unlocked brake position.

When the support vehicle 10 needs to move forward or backward, an operator controls the handle of the second reversing valve 31 to control the valve core of the second reversing valve 31 to reverse, so that the forward or backward direction of the support vehicle 10 is controlled, and meanwhile, the brake cylinder 381 controls the start and stop of the support vehicle 10.

As shown in fig. 1, the travel drive 30 further includes a second connecting line 392 disposed between the second travel line 35 and the third travel line 36, a second check valve 384 is disposed on the second connecting line 392, and one end of the second connecting line 392 is located between the output end of the first check valve 383 and the first chamber 383. When the second direction valve 31 is in the third operating state, the brake member 382 is pushed to move under the action of the brake cylinder 381, so that the brake member 382 contacts with the wheel 112, and braking is achieved. When the second direction valve 31 is in the second operating state, the compressed gas in the first chamber 392 enters the first chamber of the brake cylinder 381, the compressed gas in the first chamber pushes the brake cylinder 381 to perform position switching, so that the brake piece 382 is separated from the wheel 112, and the brake is unlocked, and meanwhile, the second one-way valve 384 can prevent the compressed gas entering the first chamber from flowing back, so that the brake piece 382 can be reliably kept at the unlocked brake position.

As shown in fig. 1, the brake cylinder 381 includes a cylinder body 3811 and a piston rod 3812 movably disposed through the cylinder body 3811.

The brake cylinder 381 further includes an elastic restoring member 3813 disposed in the second chamber, and the elastic restoring member 3813 applies an elastic force to the piston rod 3812 in a direction toward the brake member 382. Thus, when the second direction switching valve 31 is in the third operating state, the piston rod 3812 is easily returned by the elastic returning member 3813 applying an elastic force to the piston rod 3812 in a direction toward the brake member 382, so that the brake cylinder 381 reliably performs braking. The elastic restoring member 3813 is preferably a spring.

When the support vehicle 10 moves forward and the second direction-changing valve 31 is in the first working state, the compressed gas flows into the travel motor 33 and the first chamber from the first port of the travel motor 33 through the second direction-changing valve 31, and at this time, the compressed gas entering the first chamber overcomes the elastic force of the elastic reset member 3813 in the second chamber, so that the piston rod 3812 moves in the direction away from the wheel 112, the brake member 382 disengages from the wheel 112, and the brake is unlocked. At the same time, the traveling motor 33 rotationally drives the wheels 112 of the support vehicle 10 forward. In the process of advancing the wheel 112, when the second directional valve 31 is in the third operating state, no compressed gas is introduced into the travel motor 33 and the first chamber, the elastic restoring member 3813 applies an elastic force to the piston rod 3812 in the direction toward the braking member 382, and the piston rod 3812 moves in the direction toward the wheel 112, so that the braking member 382 contacts with the wheel 112, thereby achieving braking.

When the rack support cart 10 is going backwards, and the second direction valve 31 is in the second working state, the compressed air flows into the travel motor 33 and the first chamber from the second port of the travel motor 33 through the second direction valve 31, and at this time, the compressed air entering the first chamber overcomes the elastic force of the elastic reset member 3813 in the second chamber, so that the piston rod 3812 moves in the direction away from the wheel 112, the brake member 382 disengages from the wheel 112, and the brake is unlocked. At the same time, the travel motor 33 rotates the wheels 112 supporting the truck 10 to reverse. When the wheel 112 is in the reverse direction, when the second directional valve 31 is in the third operating state, no compressed gas is introduced into the travel motor 33 and the first chamber, the elastic restoring member 3813 applies an elastic force to the piston rod 3812 in a direction toward the braking member 382, and the piston rod 3812 moves in a direction toward the wheel 112, so that the braking member 382 contacts the wheel 112, thereby achieving braking.

The fourth directional control valve 54 can adjust the rotation direction of the second posture adjustment motor 55, and thus adjust the moving position of the second posture adjustment device. And then the moving distance of the rocket cabin sections on the first posture adjusting device 13 can be adjusted, and the assembly is finished after the butt joint surfaces and the butt joint points of the two rocket cabin sections are aligned.
