DETAILED DESCRIPTION

[0022] To make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the following Figures 1-9 The present invention is further described in detail with reference to the accompanying drawings and specific embodiments.

[0023] The simulated missile preparation vehicle of this embodiment includes a chassis 1. The chassis 1 longitudinal beams feature a sunken V-shaped avoidance structure that aligns with the fore-aft position of the simulated missile's wings, allowing the simulated missile's wings to avoid the missile when the missile returns to a vertical sideways position. Guide square tubes 8 are positioned at the four corners of the chassis 1. Guide posts 10 are mounted within the guide square tubes 8. The tops of the guide posts 10 are connected to lifting screws 12. The portion of the lifting screws 12 that extends out of the guide square tubes 8 passes through a slot nut 11. The stepped shaft of the slot nut 11 is embedded in a circular sunken platform fixed to a cover plate at the top of the guide square tube 8. The central hexagonal hole of a handwheel 3 is connected to the hexagonal prism of the slot nut 11. The bottom of the guide post 10 is connected to a universal wheel 9 for ground support. Turning the handwheel 3 about the lifting screw 12 drives the internal thread of the slot nut 11 to rotate, generating thrust that pushes the lifting screw 12 and the guide post 10 up and down along the guide square tube 8, synchronously supporting the chassis 1 in adjusting its height relative to the ground.

[0024] In this embodiment, toolboxes 7 are fixedly connected to the crossbeams at both ends of the chassis 1. A slewing support 4 is mounted on the mounting plate atop the toolbox 7. Five sets of roller supports are positioned along the slewing radius within the slewing support 4, supporting the front and rear slewing rings 5 ​​and 6. The roller support shafts are connected to the axial holes of the support arm plates on either side of the slewing support 4. The front and rear slewing rings 5 ​​and 6 are mounted above the roller supports within the two slewing supports 4, respectively. These five sets of roller supports share the weight of the simulated projectile, improving the system's structural strength and service life. Nylon sheaths are embedded in the roller supports to reduce vibration and noise during rotation. The arm plates of the slewing support 4 of this embodiment are provided with a mounting base and a U-shaped traction plate, and the mounting base is fixed to the mounting plate of the toolbox 7. A locking handle 14 is connected to the middle threaded hole of the U-shaped traction plate, and a clamping slider is connected to the step shaft at the front end of the screw of the locking handle 14. The traction clamping block 13 is connected to the U-shaped traction plate, and the traction clamping block 13 and the U-shaped traction plate are installed together in the guide grooves of the arm plates on both sides of the slewing support 4. Rotating the locking handle 14 moves the clamping slider forward to fit on the outer arc surface of the slewing ring, and at the same time drives the traction clamping block 13 to fit on the inner arc surface of the T-section slewing ring. As the torsional force of the locking handle 14 increases, the clamping slider and the traction clamping block 13 move toward each other to clamp the slewing ring and lock it in any position.

[0025] In this embodiment, both the front slewing ring 5 and the rear slewing ring 6 are constructed of two detachable, T-shaped, semi-circular hollow frames. Two folding latches 20 are inserted into the mounting holes of the two semi-circular rings, closing the two semi-circular rings together. The exposed portions of the folding latches 20 are folded against the sidewalls of the snap connection.

[0026] The front slewing ring 5 of this embodiment includes a front support ring 15 and a front pressure ring 16. The front pressure ring 16 is mounted on the front support ring 15 to form the front slewing ring 5. A pressure block 19 is connected to the frame of the front pressure ring 16. The pressure block 19 is suspended in the front pressure ring by a step pin. The step pin is inserted into a guide sleeve on the front pressure ring 16 and slides up and down. The other end is fixed to the pressure block 19. A compression spring 17 is installed on the shaft of the step pin. The pressure block 19 is attached to the frame of the front pressure ring 16 by the rebound thrust of the compression spring 17. The clamping screw 18 is rotated with a ratchet wrench to push the pressure block 19 inward and away from the frame to compress the simulated bullet shell. At this time, the compression spring 17 is in a compressed and retracted state. When the clamping screw 18 is rotated in the opposite direction, the pressure block 19 will be restored to its previous state of attachment to the frame of the front pressure ring 16 under the action of the rebound thrust of the compression spring 17, reset and unlock, thereby achieving rapid binding, clamping or unbinding of the simulated bullet.

[0027] The rear slewing ring 6 of this embodiment includes a rear support ring 21 and a rear clamping ring 22, and the rear clamping ring 22 is engaged and mounted on the rear support ring 21 to form the rear slewing ring 6. The reset and unlocking structure of the rear clamping ring 22 is similar to that of the front clamping ring 16. The rear clamping block 24 is suspended in the frame of the rear clamping ring 22 using a stepped shaft screw and a compression spring. The clamping push rod 23 is rotated with a ratchet wrench to push the rear clamping block 24 to press against the tail of the simulated bullet shell. At this time, the compression spring is in a compressed and retracted state. If the clamping push rod 23 is rotated in the opposite direction, the rear clamping block 24 will return to its previous suspended state under the rebound thrust of the compression spring and reset and unlock, thereby realizing the rapid binding, clamping or unbinding of the simulated bullet.

[0028] The base frame 1, the supporting rollers 2 and the slewing support 4 of this embodiment all adopt a welded assembly structure, and the front slewing ring 5 and the rear slewing ring 6 adopt a CNC machined assembly structure.

[0029] The working process of the simulated bomb preparation vehicle of this embodiment is as follows:

[0030] When the simulated bullet is ready for use, first pull out the folding pin 20 connected between the two semicircular rings, remove the front clamping ring 16 and the rear clamping ring 22, and hoist the simulated bullet onto the front support ring 15 and the rear support ring 21 (note that the positioning hole under the simulated bullet head must be aligned with the positioning pin in the middle of the front support ring 15), and install the previously removed front clamping ring 16 and rear clamping ring 22 back to their original connection positions, insert the folding pin 20 to complete the closed installation of the two rotating rings, and use a ratchet wrench to respectively rotate the clamping screw 18 and the clamping push rod 23 on the front clamping ring and the rear clamping ring to bundle and clamp the simulated bullet in the middle of the two rotating rings. The simulated bullet can be supported to rotate at any angle around the axis of the front and rear rotating rings. By twisting the locking handles 14 on both sides of the rotating support 4, the simulated bullet can be locked at any rotation position.

[0031] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
