Description

Technical Field

[0001] This utility model relates to the field of military training equipment technology, specifically to a quick assembly and disassembly device for a vehicle-mounted howitzer simulator. Background Technology

[0002] As a key piece of equipment in military training, vehicle-mounted howitzer simulators can provide soldiers with a near-real combat operational training environment while ensuring training safety and reducing the cost of live ammunition consumption. They are widely used in daily troop training and military academy teaching. However, in actual use, the existing connection methods between simulators and vehicle-mounted platforms have significant shortcomings.

[0003] Simulators and vehicle-mounted platforms are mostly connected at fixed points. If the simulator's installation position on the vehicle platform needs to be adjusted, all fixing bolts must be removed first, the simulator must be manually moved to the target position, and then recalibrated, drilled, or aligned with the fixing points. The position needs to be repeatedly adjusted to ensure accuracy, which is not only cumbersome but also consumes a lot of manpower and time. At the same time, different models and specifications of vehicle-mounted howitzer simulators have different dimensions and installation points, requiring a separate vehicle-mounted fixing structure to be designed for each simulator.

[0004] Therefore, in view of the cumbersome position adjustment and poor versatility during the disassembly and assembly process, a rapid disassembly and assembly device for a vehicle-mounted howitzer simulator is proposed to solve the problem of low disassembly and assembly efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a quick assembly and disassembly device for a vehicle-mounted howitzer simulator, in order to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A quick assembly / disassembly device for a vehicle-mounted howitzer simulator includes a support base, a locking component, a connecting seat, and a support seat. The support base is used for connection and positioning with a vehicle platform. The locking component is disposed on the support base. The connecting seat is slidably connected to the support base and is positioned and fixed by the locking component. The support seat is fixed on the connecting seat for mounting and fixing the simulator.

[0007] The support base includes a support base plate, and several evenly distributed positioning posts are welded to the bottom of the support base plate. The positioning posts are clearance-fitted with the positioning holes preset on the vehicle platform. Several mounting holes are opened around the perimeter of the support base plate and at the midpoint of its long side. Bolts are inserted into the mounting holes to fix the support base plate to the vehicle platform. Guide rails are fixed on both sides of the support base plate along the length direction. Several positioning holes are evenly opened on the inner wall of each guide rail.

[0008] The locking assembly comprises several units and is fixed to a base plate between two guide rails. Each locking assembly includes a central component, a fixed shaft, an electric push rod, a positioning shaft, and a telescopic pin. The central component has fixed shafts threaded to both ends, and the ends of the fixed shafts are fixedly connected to the positioning shafts. A through hole is formed within the fixed shaft, extending into the interior of the central component. An installation cavity is machined inside the central component, and the electric push rod is fixedly installed within the installation cavity. The electric push rod is a bidirectional synchronous telescopic electric push rod. The output ends of the electric push rod extend into the through holes of the corresponding fixed shafts, and telescopic pins are fixed to the end faces of the output ends of the electric push rods. The telescopic pins penetrate the positioning shaft and are slidably connected to it. The positioning shaft is aligned with a positioning hole, allowing the telescopic pins to engage with the positioning hole.

[0009] The bottom of the connecting seat is fixed with a slider adapted to the guide rail. The slider has a second positioning hole, which matches the diameter of the first positioning hole. When the connecting seat slides to the target position, the second positioning hole aligns with the first positioning hole. A crossbar is provided on one side of the connecting seat. An ear plate is fixed on the side of the connecting seat corresponding to the crossbar. The crossbar is rotatably connected to the ear plate by a pin. A positioning slot is provided below the crossbar, which can engage with the guide rail.

[0010] The support base is fixed to the top of the connecting base, and a number of positioning pins are fixed on the support base. The positioning pins are used to cooperate with the positioning slots preset on the bottom of the simulator for positioning.

[0011] This utility model further illustrates that the electric push rod is connected to a controller, which can be integrated into the control panel of the vehicle platform to realize remote control of the electric push rod, eliminating the need for operators to manually adjust the telescopic pin and improving operational convenience.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model, (1) By setting the electric push rod in the guide rail and locking assembly, the connecting seat can slide and cooperate with the guide rail of the bearing base through the bottom slider, and can move flexibly to the target position along the guide rail; the locking assembly adopts a bidirectional synchronous telescopic electric push rod to drive the telescopic pin.

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a quick assembly and disassembly device for a vehicle-mounted howitzer simulator, including a support base 1.

[0016] like Figure 1-3 As shown, the support base 1 includes a support base plate 101. Several evenly distributed positioning posts 102 are welded to the bottom of the support base plate 101, which cooperate with pre-set positioning holes on the vehicle platform to achieve pre-positioning of the support base 1 with the vehicle platform and prevent displacement during installation. Several mounting holes 103 are respectively opened around the perimeter of the support base plate 101 and at the midpoint of its long side. The mounting holes 103 are used to fix the support base 1 to the vehicle platform.

[0017] like Figure 3-4As shown, guide rails 104 are fixed on both sides of the bearing base plate 101 along the length direction. Each guide rail 104 has a positioning hole 1041 on its inner wall. The positioning holes 1041 are evenly distributed along the guide rail 104 so as to be adjusted according to the different installation positions of subsequent components. A plurality of locking components 2 are fixedly provided on the supporting base plate 101 between the two guide rails 104. Each locking component 2 includes a central component 201. The two ends of the central component 201 are respectively connected to fixed shafts 202 by threads. The ends of the fixed shafts 202 are connected to positioning shafts 204. Each fixed shaft 202 has a through hole and extends into the interior of the central component 201. The central component 201 has a mounting cavity for accommodating and fixing an electric push rod 203. The electric push rod 203 is a bidirectional synchronous telescopic electric push rod. The two output ends of the electric push rod 203 extend into the through holes in the fixed shafts 202, and telescopic pins 205 are respectively fixed on the end faces. The telescopic pins 205 pass through the positioning shafts 204 and are slidably connected to them. The positioning shafts 204 are aligned with the positioning hole 1041, so that the telescopic pins 205 cooperate with the positioning hole 1041 to realize the functions of retraction unlocking and extension locking.

[0018] like Figure 1-4 As shown, a connecting seat 3 is slidably connected to the guide rail 104. A slider adapted to the guide rail 104 is fixedly installed at the bottom of the connecting seat 3, and a second positioning hole 301 is provided on the slider. A crossbar 302 is provided on one side of the connecting seat 3. The crossbar 302 is rotatably connected to an ear plate on one side of the connecting seat 3 via a pin. A positioning slot is provided below the crossbar 302. By manually pulling the crossbar 302 downwards, the positioning slot engages with the guide rail 104, further securing the connecting seat 3. After the connecting seat 3 slides along the guide rail 104 to the working position, the electric push rod 203 is controlled to extend to both ends, causing the telescopic pin 205 to extend and pass through the first positioning hole 1041 and the second positioning hole 301 in sequence, thus positioning the connecting seat 3. The crossbar 302 then provides further fixation.

[0019] A support base 4 is fixed on the connecting seat 3. The support base 4 serves to fix and support the simulator 5. The support base 4 is provided with several positioning pins to ensure that the simulator 5 can be quickly aligned during installation. At the same time, the simulator 5 is connected to the support base 4 by quick-release bolts.

[0020] Working principle: During use, the positioning posts 102 below the supporting base plate 101 form a clearance fit with the pre-set positioning holes on the vehicle platform. The guiding effect of the positioning posts 102 quickly completes the initial alignment, restricting the horizontal displacement of the supporting base 1 and preventing displacement due to force during bolt installation, thus providing a reference for subsequent fixing. The mounting holes 103 around the perimeter and at the midpoint of the long side of the supporting base plate 101 are connected to the vehicle platform by bolts. After the bolts are tightened, the supporting base plate 101 fits tightly against the vehicle platform, evenly transferring the weight of the simulator 5 and the vehicle vibration load to the vehicle platform, ensuring the stability of the overall structure in dynamic environments.

[0021] The guide rail 104 and the connecting seat 3 form a linear sliding adjustment mechanism, enabling flexible adaptation of the simulator's installation position. The guide rails 104 on both sides are fixed parallel to the length of the supporting base plate 101. The slider at the bottom of the connecting seat 3 adapts to the rail, forming a sliding fit, allowing the connecting seat 3 to move smoothly along the guide rail 104. The evenly spaced positioning holes 1041 on the inner wall of the guide rail 104 provide multiple position options for the connecting seat 3, meeting the installation requirements of simulators of different specifications or vehicle-mounted layouts. The positioning hole 301 on the slider of the connecting seat 3 matches the diameter of the positioning hole 1041 on the rail. When the connecting seat 3 slides to the target position, the two holes align, forming the working reference of the locking component 2, completing the positioning preparation without additional calibration tools.

[0022] The locking assembly 2 and the crossbar 302 achieve reliable positioning of the connecting seat 3 through electric drive and mechanical reinforcement. The bidirectional electric push rod 203 within the central component 201 drives the telescopic pins 205 at both ends to move synchronously. When the connecting seat 3 is in position, the electric push rod 203 extends, causing the telescopic pins 205 to pass sequentially through positioning hole one 1041 and positioning hole two 301. The engagement of the pins and holes restricts the sliding freedom of the connecting seat 3, completing the initial locking. During unlocking, the electric push rod 203 retracts, and the telescopic pins 205 exit their positions, releasing the constraint. The crossbar 302 on one side of the connecting seat 3 rotates via a pin shaft. When pulled downwards, its bottom positioning groove engages with the guide rail 104, forming a secondary fixation. This structure prevents the telescopic pins 205 from loosening due to long-term vibration, enhancing locking reliability.

[0023] As the direct load-bearing component of the simulator 5, the positioning pin on the support base 4 quickly guides the simulator 5 to align with the support base 4, reducing the position adjustment time during installation and ensuring docking accuracy. The simulator 5 and the support base 4 are connected by quick-release bolts, which can be installed and removed without complicated tools. With the guiding effect of the positioning pin, the docking time is greatly reduced.
