Description

Technical Field

[0001] This utility model relates to the field of ammunition handling technology, specifically to an automatic ammunition lifting system. Background Technology

[0002] Traditional turret-based ammunition resupply methods suffer from significant efficiency and safety deficiencies. Operators must move heavy ammunition boxes in confined vehicle compartments using unnatural postures. The irregular size and weight of these boxes exceed standard manual handling requirements, leading to increased physical exertion and a higher risk of musculoskeletal injuries. When transferring ammunition to the roof, operators must work on an unprotected platform, facing the risk of falls and struggling to maintain balance due to the platform's lack of stability. The entire process requires repeated trips back and forth without mechanical assistance, resulting in prolonged downtime and severely impacting equipment's continuous operational capability. This purely manual operation mode can no longer meet the demands of efficient, safe, and sustainable modern mechanical system maintenance. Utility Model Content

[0003] The purpose of this invention is to provide an automatic ammunition lifting system to solve the problems of low efficiency and safety defects in traditional ammunition resupply methods.

[0004] To achieve the above objectives, an automatic ammunition lifting system is provided, comprising an opening assembly, a lifting assembly, and a controller. The opening assembly includes a top cover, a rotating rod, bearing seats, a coupling, and a motor. The rotating rod is inserted into two bearing seats, and one end of the rotating rod is connected to the motor via the coupling. The end of the top cover is fixed to the rotating rod and rotates together with the rotating rod to open and close the ammunition box inlet and outlet. The lifting assembly is located directly below the ammunition box inlet and outlet and includes a base, a scissor arm, an electric cylinder, and a support plate. The base and support plate are respectively located at the upper and lower ends of the scissor arm. The electric cylinder is used to drive the scissor arm to extend and retract. Both the motor and the electric cylinder are electrically connected to the controller.

[0005] Furthermore, the upper surface of the pallet is provided with folding plates at both ends.

[0006] Furthermore, the pallet is provided with several rolling components, each including a support base and a ball bearing. The ball bearing is rotatably connected to the support base to support the ammunition box.

[0007] Furthermore, it also includes a control box, in which the controller is disposed, and a control panel is disposed on the outer surface of the control box, the control panel being electrically connected to the controller.

[0008] Furthermore, the control panel is equipped with a first indicator light, which corresponds to a control button on the control panel.

[0009] Furthermore, it also includes a control handle, which is equipped with control buttons and is electrically connected to the controller.

[0010] Furthermore, the control handle is equipped with a second indicator light, which corresponds to a control button.

[0011] Furthermore, the ammunition box inlet and outlet are covered with a ring of shock-absorbing rubber strips.

[0012] Furthermore, a buffer layer is provided on the bottom surface of the top cover that contacts the shock-absorbing rubber strip.

[0013] Furthermore, the buffer layer is a silicone buffer layer or a rubber buffer layer.

[0014] Principles and advantages:

[0015] This solution is an advanced device designed for the automated operation of vehicle ammunition boxes. It mainly consists of an opening assembly and a lifting assembly. When opening the lid: a motor drives a rotating rod, which in turn rotates the top cover counter-clockwise around the rod, opening the lid. When closing: the rotating rod drives the top cover clockwise around the rod, closing the lid. Lifting function: Pressing the platform lifting switch on the control panel activates the electric cylinder, moving the pallet upwards slightly above the vehicle roof platform and locking itself. Workers can then pull out the ammunition to complete the loading process. Lowering function: Workers first push the empty ammunition box back onto the pallet; then pressing the lowering switch on the control panel activates the electric cylinder, lowering the platform. After the pallet moves down to its reset position, it automatically stops and locks itself. After removing the empty ammunition box from the pallet, the folding plate can be opened to pull in the second set of ammunition boxes, enabling rapid, safe, and efficient loading and unloading of ammunition boxes, significantly improving combat and operational efficiency.
