Description
Technical Field
The invention relates to the technical field of military equipment, in particular to a beam type screw thread quick-adjusting low-temperature-freezing-resistant carrier.
Background
At present, ammunition (multiple rounds of ammunition, generally 16-24 rounds of fixed package and 8-12 rounds of split package) which is kept at high temperature, normal temperature and low temperature (-40 ℃ even lower) is required to be transported to specific places by an ammunition heat-preserving transport vehicle in the ammunition test process of a conventional weapon test range in China, the ammunition is required to be insulated and reliably fixed in the low-temperature transport process, dangers are prevented from occurring in the ammunition movement, the ammunition is required to be transported to a designated place for taking after being transported to specific places in a partitioning mode, the procedure is to load the ammunition into the ammunition heat-preserving transport vehicle heat-preserving box from the ammunition heat-preserving test workshop heat-preserving test box in a partitioning mode, 8-24 rounds of ammunition are required to be taken after each time when the heat-preserving transport reaches a test site, and each round of ammunition is required to be transported to a shooting place in a vehicle mode. After the first vehicle is shot, the vehicle can return to an ammunition heat preservation test workshop to power up and preserve heat, and after the temperature reaches the required temperature, ammunition is continuously clamped, and heat preservation is transported to a test site to carry out the next group of shooting tests. Because the ammunition thermal insulation conveying vehicle continuously carries out round trip transportation, opens a door to fetch and put ammunition, the ammunition is required to be clamped and fixed reliably in the transportation process, and the ammunition cannot be leaped; in addition, as the temperature in the thermal insulation test box is low (-40 ℃ even lower), and the outdoor environment temperature in summer is 30-40 ℃ in zero, the vehicle-mounted thermal insulation box can cause convection of internal air and external air, frosting and icing can occur when hot air meets a low-temperature bullet carrying frame, meanwhile, repeated power-on thermal insulation can enable an ice layer to be thicker and thicker, finally, the bullet carrying frame is frozen and cannot be operated, and ammunition transported each time is various in types, different in caliber and length, and larger in diameter difference between a bullet and a cartridge case even if ammunition with the same caliber is used. This requires the device to load the ammunition: ① At least ten bare ammunition can be transported simultaneously; ② Can adapt to ammunition with various lengths (generally smaller than 2 m) and various calibers (60 mm-240 mm); ③ The central axis of the ammunition transportation process is vertical to the running direction of the transport vehicle; ④ The ammunition is reliably loaded, clamped and fixed, and the operation of taking and placing is fast and convenient; ⑤ Can adapt to extreme high and low temperature environments.
The existing bullet carrying frame adopts either a four-bar mechanism or a vertical rod inverted tooth buckle type mechanism. The four-bar mechanism has the advantages of high clamping speed, low adjusting speed and small adjustable range, and the defects of frequent adjustment due to different caliber of the spring seeds in each test can not meet the requirements of all spring seeds with different calibers. When the vertical rod inverted tooth buckle type mechanism is used, firstly, the tooth pins at two sides are pulled out, the tooth pins rotate 90 degrees clockwise, then the fixed clamping beam type mechanism is lifted upwards along the vertical rods at two sides, and then the tooth pins rotate 90 degrees anticlockwise to stop the fixed clamping beam type mechanism at the top end of the vertical rod, after ammunition is pushed in place, the fixed clamping beam type mechanism is pressed downwards forcefully, and the fixed clamping mechanism in the middle of the beam type mechanism is screwed in place tightly so as to fasten the ammunition. The device has the advantages of being capable of adapting to different caliber bullet seeds, free of adjustment and high in operation speed, and has the defects that due to the fact that the plug-in toothed pin and the teeth on the vertical rod exist, when the bullet carrying frame frosts and freezes, the phenomenon that the bullet carrying frame is frozen and cannot be operated easily occurs, the test operation efficiency is affected, and great potential safety hazards are brought to heat preservation and transportation of ammunition.

The V-shaped bullet supporting plate 21 is formed by pressing an aluminum plate with the thickness of 8mm, the anti-movement structure 23 is also made of aluminum materials, so that the surface of the ammunition is prevented from being damaged by collision with the ammunition and the safety of the electrically-ignited ammunition is prevented from being endangered by sparks, and other parts, except the V-shaped bullet supporting plate and the anti-movement structure 23, which are easy to contact and collide with the ammunition are made of aluminum materials, are made of stainless steel materials or stainless steel thickened square tubes.
Before the bullet carrying frame is used, the fixed beams 7 are adjusted to proper height by the first rotating parts 3 according to the caliber of two ammunition to be placed at each station, the two ammunition are respectively placed on the V-shaped bullet supporting plates at the left side and the right side, pushed and pulled in place (a cartridge with a bottom edge clamps the bottom edge on the outer edge of the V-shaped bullet supporting plates), the pressing block fixing parts are quickly adjusted to be in place by the second rotating parts 8, then the ammunition is rotated and pressed by the second screw rods 9, the ammunition is locked by the self-locking action of threads, and finally the anti-movement baffle is rotated to limit, so that the aim of firmly fixing the ammunition is fulfilled.
When the ammunition is taken out, the second rotating part 8 is rotated firstly to loosen and clamp the ammunition, then the first rotating part 3 is used for rapidly lifting the fixed beam 7 to release enough operation space, the anti-channeling structure 23 is rotated, and the ammunition is taken out; if a single round of ammunition is taken, the remaining ammunition is clamped again in the same manner as described above. The same operation is performed on a gradual basis. The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
