[0002] In recent years, with the vigorous development of the aerospace industry, especially the development of aerospace enterprises, rocket models are being updated and iterated at an accelerated pace. The number of rocket models requiring transportation is increasing, placing higher demands on transport vehicles. After rocket development is completed, the rocket body and spacecraft need to be transferred from the vertical assembly and testing facility to the launch tower. Current technologies for transporting rocket bodies and spacecraft generally include horizontal and vertical transportation.

[0003] During horizontal transport, the rocket body needs to be changed from a horizontal to a vertical position before reaching the launch tower. After being erected, the rocket body needs to be inspected again. Vertical transport, on the other hand, involves transporting each part of the rocket body vertically separately.

[0004] In order to reduce costs, semi-trailers are generally used for transportation in the current technology. During horizontal transportation, the rocket body needs to be fixed. The existing devices for fixing the rocket body include support platforms. The side of the support platform near the rocket body is provided with an arc-shaped surface. However, after installation, such support platforms can only support the rocket body and pose safety hazards during transportation. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example This utility model provides a clamping device for a horizontal transport vehicle, see [link / reference]. Figures 1-5 It includes a support base 100, on which an arc-shaped tray 200, a clamping arm 300, a drive assembly 400, and a locking assembly 600 are provided.

[0019] The arc-shaped tray 200 is located directly above the support base 100 and is used to support and limit the arrow body. The upper end of the arc-shaped tray 200 is arc-shaped to support the arrow body. The arc-shaped tray 200 and the support base 100 are fixedly connected, and reinforcing ribs 210 are provided on both sides. The clamping arms 300 are located on both sides of the arrow body and are rotatably connected to the support base 100. The clamping arms 300 can rotate to approach or move away from the arrow body. When rotating to approach the arrow body, they clamp and fix the arrow body. The drive assembly 400 drives the clamping arms 300 to rotate; the locking assembly 600 is located on the side of the support base 100 near the transport frame and locks the frame and the support base 100.

[0020] During operation, the appropriate clamping device is selected based on the model of the arrow body being transported, and the device is fixedly installed on the transport vehicle using the locking assembly 600. After installation, the arrow body is supported from below by an arc-shaped support plate. The arrow body is limited on both sides by clamping arms 300.

[0021] Specifically, the support base 100 is a cuboid frame, and the clamping arm 300 is arc-shaped. The end of the clamping arm 300 near the support base 100 has a first hinge point 310 and a second hinge point 320.

[0029] The limiting frame 540 is fixed to one end of the clamping arm 300 near the supporting base 100, and the limiting frame 540 is located between the two sets of drive components 500. A limiting hole 541 is provided in the limiting frame 540. When the clamping arm 300 clamps the arrow body, the limiting hole 541 is in a horizontal state and is coaxial with the sliding hole 511. When the limiting block 530 slides horizontally, it can enter the limiting hole 541.

[0030] By using the limit component 500, the position of the clamping arm 300 can be assisted in locking after the arrow body is clamped.

A locking pin 640 is slidably connected in one of the locking sleeves 630. The third hydraulic cylinder 620 is fixed on the support base 100, and the piston end of the third hydraulic cylinder 620 is connected to the locking pin 640. When the piston end of the third hydraulic cylinder 620 extends, it drives the locking pin 640 to slide in the locking sleeve 630. The locking pin 640 can pass through the locking hole 611 or disengage from the locking hole 611.
