Description

Technical Field

[0001] This utility model relates to the field of artillery obstacle removal technology, and in particular to a quick disassembly tool for maintenance doors. Background Technology

[0002] The tracked 155mm self-propelled howitzer's rotating magazine uses an electronically controlled circulating ammunition belt. The rotating magazine, in conjunction with a loader, pushes projectiles into the magazine tray. During live-fire exercises, magazine malfunctions frequently occur, requiring the rapid opening of the maintenance door for repairs to the loader and magazine. However, because the maintenance door must serve to protect against dust, equipment, and personnel inside the turret, it has a certain thickness of armor, making it heavy and requiring tight installation. Furthermore, the inability to freely adjust the direction of the turret barrel during live-fire exercises further complicates opening the maintenance door. There are currently three main methods for opening the maintenance door: (1) Usually, the ammunition feeder is used to pry open the maintenance door from the inside, but this can easily damage the related circuit wires of the ammunition feeder and rotating magazine; and if the gun barrel is not aligned properly, the maintenance door cannot be opened by the ammunition feeder; (2) The maintenance door is opened manually by pulling it with a steel cable. The maintenance door is extremely heavy, which not only requires a lot of manpower and physical exertion, but also often takes a long time. Moreover, the maintenance door is still difficult to open if it is too tight; (3) For particularly tight maintenance doors, a vehicle is needed to pull the steel cable to open them. None of these methods can open the maintenance door quickly and flexibly. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a simple and reasonably designed quick disassembly tool for maintenance doors. It not only improves work efficiency and saves manpower and physical strength, but also avoids safety accidents caused by shooting into non-target areas. Furthermore, it occupies little space and is easy to carry.

[0004] To achieve the above objectives, this utility model provides a quick disassembly tool for maintenance doors, including a gantry structure with a threaded pull-out mechanism; the gantry structure includes an adsorption seat connected to a column, the column connected to a crossbeam, and the crossbeam having an internal threaded sleeve; the pull-out mechanism includes a threaded rod threadedly connected to the internal threaded sleeve, one end of the threaded rod being rotatably connected to a hook, and the other end of the threaded rod being engaged with a handle.

[0005] Furthermore, the column is made of a round tube, and a connector is provided at the end of the column that connects to the adsorption seat. The diameter of the connector is smaller than that of the column. A step is machined at the end of the column that connects to the crossbeam, and the step is inserted into the crossbeam.

[0006] Furthermore, the adsorption base includes a rectangular outer shell, inside which a switch magnet is provided. Turning on the switch magnet will cause the adsorption base to adhere to both ends of the maintenance door. The outer shell is provided with a connection hole, which connects to the connector.

[0007] Furthermore, the connector is a cylinder or a threaded cylinder, and the connecting hole is a round hole or a threaded hole.

[0008] Furthermore, the crossbeam includes a square tube, the internal threaded sleeve passes radially through the square tube and is welded to the square tube; the square tube is closed at both ends and fixedly connected to sleeves at both ends, and the stage is inserted into the sleeves.

[0009] Furthermore, one end of the threaded rod is provided with a square groove, and the other end of the threaded rod is provided with a round shaft, the end of which is provided with a radial pin hole.

[0010] Furthermore, the hook includes a plate-shaped rotating base with a through hole at its center, and the round shaft is rotatably connected to the through hole; the rotating base is fixedly connected to a U-shaped locking ring one, the locking ring one is connected to a U-shaped locking ring two, and the locking ring two is fixedly connected to a bent hook.

[0011] Furthermore, the handle includes segment one and segment two, which are vertically connected. Segment one is connected to a square head, the axis of which is parallel to that of segment two, and the square head mates with the square groove. Segment two is rotatably fitted with a rotating cylinder.

[0012] The beneficial effects of this scheme can be seen from the description above. It has a simple structure, reasonable design, and the following advantages:

[0013] (1) Improved work efficiency, reducing the time to disassemble the maintenance door from 30 minutes to 6 minutes, which is of great significance in the battlefield environment and fills the gap of the lack of maintenance door disassembly tools for tracked 155 self-propelled guns;

[0014] (2) Changing the firing direction during live-fire shooting is dangerous and can easily lead to safety accidents. This plan allows the maintenance door to be opened safely and quickly without turning the turret, thus avoiding the accident of firing into non-target areas.

[0015] (3) There is no requirement for the number of personnel when disassembling the maintenance door, and the disassembly work does not require excessive physical exertion, which plays an important role in saving manpower and physical energy;

[0016] (4) Whether it is the connection structure composed of adsorption seat, crossbeam and column, or the lifting structure composed of threaded rod, hook and handle, it can be disassembled into rods or small parts when stored, occupying little space and being portable.
