[0014] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] like Figure 1-7As shown, in this embodiment, a universal turret assembly / disassembly stand that can be quickly adjusted includes a drive mechanism 1. Four synchronously moving mechanisms 2 are fixedly connected to the drive mechanism 1. Two of the synchronously moving mechanisms 2 are equipped with movable rear hydraulic cylinders 3, and the other two are equipped with movable front hydraulic cylinders 4. Support plates 5 are mounted on the tops of the rear and front hydraulic cylinders 3 and 4. The four support plates 5 synchronously expand or shrink in diameter along their center to support turrets of different specifications, achieving universality. The drive mechanism 1 includes a drive housing. 101, bearing housing 102, lower bevel gear 103, upper bevel gear 104, central shaft 105, rotating wheel 106, driven bevel gear 107. The drive housing 101 is a rectangular housing, with bearing housings 102 fixedly installed at the top and bottom centers. The lower bevel gear 103 and upper bevel gear 104 are mirror-mounted inside the drive housing 101. The lower bevel gear 103 is interference-fitted to the lower bearing housing 102 via a shaft, and the upper bevel gear 104 is interference-fitted to the upper bearing housing 102 via a central shaft 105. The central shaft 105 extends out of the drive housing. A rotating wheel 106 is fixedly installed on the top of the body 101, which can drive the upper bevel gear 104 to rotate by manual rotation. Four driven bevel gears 107 are evenly distributed between the lower bevel gear 103 and the upper bevel gear 104 and mesh with it. The design of the lower bevel gear 103 and the upper bevel gear 104 makes the driven bevel gears 107 more stable when rotating and also allows the four driven bevel gears 107 to rotate synchronously. The synchronous movement mechanism 2 includes a screw box 201, a screw 202, a slider 203, and a nut 204. The top of the screw box 201 is open and connected to... The drive housing 101 is fixed. A screw 202 is installed in the screw housing 201 through bearings. Each screw 202 is fixed to the center of the corresponding driven bevel gear 107. A slider 203 is provided in the screw housing 201 and slides along its interior. A nut 204 is fixed in the slider 203 and cooperates with the screw 202. The top of the slider 203 passes through the top opening of the screw housing 201 and is fixed to the bottom of the rear hydraulic cylinder 3 and the front hydraulic cylinder 4. The self-locking property of the screw 202 and the nut 204 ensures the stability of the position of the rear hydraulic cylinder 3 and the front hydraulic cylinder 4.

[0017] Specifically, the rotary wheel 106 is less prone to damage and easier to replace than a motor, making it more suitable for field maintenance. When the rotary wheel 106 in the drive mechanism 1 is rotated manually, it drives the upper bevel gear 104 to rotate, which in turn drives the four driven bevel gears 107 to rotate synchronously, evenly transmitting power to the screws 202 of the four synchronous movement mechanisms 2. When the screws 202 rotate, the nuts 204 that cooperate with them drive the sliders 203 to slide synchronously within the screw box 201, thereby achieving synchronous movement of the front and rear hydraulic cylinders. Compared to traditional multi-person collaborative work, the rotary wheel 106 can be used by only one person, greatly improving the work efficiency of the platform.

[0018] Four driven bevel gears 107 are fixedly mounted with connecting shafts 108 at their centers. The connecting shafts 108 are mounted to the drive housing 101 via bearings. The outer side of the connecting shafts 108 has a rectangular groove 109. The inner end of the screw 202 has an integrally formed rectangular head 205. The rectangular head 205 is inserted into the rectangular groove 109, so that the screw 202 can rotate synchronously with the connecting shafts 108. The screw housing 201 is mounted to the drive housing 101 with bolts.

[0019] Specifically, the screw box 201 and the drive housing 101 are detachable, and the screw 202 and the connecting shaft 108 are plug-in positioned. During field maintenance, this greatly reduces the space occupied when the vehicle is loaded. The plug-in connection between the rectangular slot 109 and the rectangular head 205 also facilitates disassembly and maintenance, improving the maintainability of the entire platform. This not only improves the platform's operational efficiency but also provides strong support for the maintenance and upkeep of the turret.

[0020] The screw box 201 has multiple slider positioning holes 206 on its outer side. The top outer side of the slider 203 is welded with two side plates 207. A slider positioning pin 208 is inserted into the through hole in the middle of the side plate 207. The slider positioning pin 208 is threadedly connected to any slider positioning hole 206.

[0021] Specifically, the slider 203 is locked by the slider positioning pin 208 and the slider positioning hole 206, which prevents the support plate 5 from moving due to accidental contact with the rotating wheel 106. This effectively ensures operational safety and improves the stability and reliability of the operation through a simple mechanical locking mechanism.

[0022] The screw box 201 is vertically fixed to the outside of the wing plate 209 for ground support, which increases the contact area between the screw box 201 and the ground, thereby improving the stability of the entire platform during operation.

[0023] A dust cover 210 is installed at a position on the top of the screw box 201. One side of the dust cover 210 is fixed to the screw box 201, and the other side is fixed to the slider 203.

[0024] Specifically, the dust cover 210 is foldable and can extend and retract with the movement of the slider 203, effectively blocking dust, debris and other impurities from entering the screw box 201. This prevents jamming or wear between the screw 202 and the nut 204 due to impurities, thereby extending the service life of the synchronous moving mechanism 2 and reducing the maintenance cost of the equipment.

[0025] A lower hinge seat 301 is installed between the bottom of the rear hydraulic cylinder 3 and the slider 203. The rear hydraulic cylinder 3 and the front hydraulic cylinder 4 are hinged to the support plate 5, and the rotation direction of each hinge and the lower hinge seat 301 is in the same direction. This allows the rear hydraulic cylinder 3 to rotate through the lower hinge seat 301, so that when the front hydraulic cylinder 4 is lowered, the top turret can be tilted, making it easier to remove the gun barrel from the turret for maintenance. An auxiliary rod 6 is fixedly installed between each adjacent support plate 5. The auxiliary rod 6 enhances the structural stability between the support plates 5. When the support plate 5 supports the turret, the auxiliary rod 6 can disperse the pressure exerted by the turret on the support plate 5, avoiding deformation of the support plate 5 due to excessive local pressure, thereby ensuring the safety and reliability of the entire platform during the turret support process.

[0026] Two sleeves 501 are hinged to two adjacent support plates 5. The sleeves 501 are used to hold the auxiliary rod 6 and are fixed at the bottom by bolts. The sleeves 501 are externally threaded with fixing bolts 502. Multiple auxiliary rod positioning holes 601 are opened on the outer wall of one end of the auxiliary rod 6. The fixing bolts 502 are inserted into the auxiliary rod positioning holes 601.

[0027] Specifically, through the cooperation of the sleeve 501 and the auxiliary rod 6, the auxiliary rod 6 can be flexibly installed and positioned at different spacings of the support plates 5. When it is necessary to adjust the spacing of the support plates 5 to accommodate different turret specifications, simply loosen the fixing bolt 502, move the auxiliary rod 6 to the appropriate position, and insert the fixing bolt 502 into the corresponding auxiliary rod positioning hole 601 to complete the repositioning and fixing of the auxiliary rod 6. This improves the adaptability of the platform, ensures the stability of the auxiliary rod 6 during the support process, and further enhances the safety and reliability of the entire platform.

[0028] This assembly / disassembly stand also includes a hydraulic system 7 and an electrical box 8.

[0029] Specifically, hydraulic system 7 provides power to the rear hydraulic cylinder 3 and the front hydraulic cylinder 4, ensuring their stable and powerful telescopic movements, thereby achieving precise adjustment of the turret tilt angle. Electrical box 8 provides power to the entire assembly / disassembly platform's electrical system. It incorporates multiple safety protection devices, including overload protection and short-circuit protection, effectively preventing accidents caused by electrical faults. Through the coordinated operation of hydraulic system 7 and electrical box 8, this assembly / disassembly platform enables efficient, safe, and stable turret assembly / disassembly operations, providing strong technical support for turret maintenance and upkeep.

[0030] The working principle of this utility model is as follows: When using this universally adjustable turret assembly / disassembly stand, first adjust the spacing of the support plates 5 according to the specifications of the turret to be assembled / disassembled. The operator manually rotates the wheel 106 in the drive mechanism 1, which drives the upper bevel gear 104 to rotate. The upper bevel gear 104 then drives the four driven bevel gears 107 meshing with it to rotate synchronously. Since the driven bevel gears 107 are fixed to the center of the screw 202 in the synchronous movement mechanism 2, the screw 202 also rotates accordingly. When the screw 202 rotates, the nut 204 that cooperates with it drives the slider 203 to slide in the screw box 201. The top of the slider 203 is fixed to the bottom of the rear hydraulic cylinder 3 and the front hydraulic cylinder 4, thereby realizing the synchronous movement of the front and rear hydraulic cylinders. At the same time, the auxiliary rod 6 is positioned and fixed to the clip 501 by the insertion of the fixing bolt 502 into the auxiliary rod positioning hole 601.

[0031] Once the support plate 5 is moved to the appropriate position, the slider 203 is locked by the cooperation of the slider positioning pin 208 and the slider positioning hole 206, preventing the support plate 5 from moving due to accidental contact with the rotating wheel 106 and ensuring operational safety. If further adjustment of the tilt angle of the support plate 5 is required for better turret assembly and disassembly, the hydraulic system 7 can provide power to the rear hydraulic cylinder 3 and the front hydraulic cylinder 4 to perform telescopic movements, thereby achieving precise adjustment of the turret tilt angle.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
