Description

Technical Field

[0001] This utility model relates to the field of transportation safety technology, and in particular to a slide system for loading and unloading ammunition. Background Technology

[0002] Military transport vehicles carry ammunition boxes at relatively high positions, and the lifting height from the ground to the transport vehicle often exceeds two meters. The ammunition boxes are heavy, often weighing hundreds of kilograms. Previously, lifting ammunition relied mainly on manpower, requiring multiple people to work together. During manual lifting, uneven force or exhaustion can easily cause the boxes to tilt or slip, posing safety hazards. Even if an accident is avoided, a significant impact can damage the ammunition. Furthermore, long-distance vertical lifting requires repeated lifting or the use of temporary steps, resulting in poor stability and increasing the risk of muscle strains or lower back injuries. Utility Model Content

When lifting ammunition boxes, the boxes are less likely to slip, thus ensuring safety and protecting the quality of the ammunition. It also saves physical energy, allowing personnel to devote more energy to performing tasks. An anti-slip mechanism is included to prevent the ammunition boxes from sliding to the bottom even if the steel cable breaks or loosens, further protecting the ammunition boxes. The slide assembly is divided into several parts, thereby improving portability.

[0040] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution. Example 1

[0041] like Figures 1-3 As shown, this embodiment is a slide system for loading and unloading ammunition, including a slide assembly. The slide assembly includes an upper assembly 1 and a lower assembly 2 connected to each other. The upper assembly 1 includes an upper frame 11, which includes upper longitudinal beams 111 located on both sides of the upper frame 111. An upper crossbeam 112 is connected between the upper longitudinal beams 111, and an upper wheel rail 12 is connected to the upper side of the upper longitudinal beams 111. The lower assembly 2 includes a lower frame 21, which includes lower longitudinal beams 211 located on both sides of the lower frame 211. A lower crossbeam 212 is connected between the lower longitudinal beams 211, and a lower wheel rail 22 is connected to the upper side of the lower longitudinal beams 211. The upper wheel rail 12 and the lower wheel rail 22 are joined at their ends. The upper frame 11 is also connected to an upper panel, and the lower frame 21 is also connected to a lower panel.

[0042] A support frame 3 is connected at the connection between the lower longitudinal beam 211 and the upper longitudinal beam 111. The support frame 3 includes a floor 31, to which a support column 32 is connected. The support frame 3 also includes a channel steel member 33 with its groove facing downward. Angle steel members 34 are connected to both ends of the upper side of the channel steel member 33. One end of the angle steel member 34 is connected to the outer and lower sides of the upper longitudinal beam 111, and the other end of the angle steel member 34 is connected to the outer and lower sides of the lower longitudinal beam 211. The angle steel member 34 is bolted to the outer side of the upper longitudinal beam 111 and to the outer side of the lower longitudinal beam 211. A hinge seat 35 is connected to the groove of the channel steel member 33, and the hinge seat 35 is hinged to the support column 32. The hinge axis of the hinge seat 35 is perpendicular to the longitudinal line of the channel steel member 33, and the hinge axis of the hinge seat 35 intersects with the plane containing the web of the channel steel member 33.

[0043] It also includes a transfer trolley 4, which includes a frame 41. The frame 41 is connected to a track wheel 42, which is rotatably connected to an upper wheel rail 12 or a lower wheel rail 22. The track wheel 42 is movably connected to a wheel seat 43, which is connected to a wheel axle, and the wheel axle is movably connected to the track wheel 42. The wheel seat 43 and the wheel axle are mounted on the upper surface of the frame 41.

[0044] It also includes a traction mechanism, which includes a steel wire rope 5. The ammunition box 6 is placed on the transfer trolley 4 and is tied and pulled by the steel wire rope 5.

[0045] The bottom of the lower wheel rail 22 and the lower longitudinal beam 211 are wedge-shaped and connected to the floor 23 for connection with the ground screws.

[0046] like Figure 4 As shown, the upper end of the upper longitudinal beam 111 is connected to the bearing seat 13, and the bearing seats 13 are connected to the conveyor rollers 14; when the transfer trolley 4 moves on the wheel rail, with the plane where the wheel rail is located as the reference, the height of the bottom of the frame 41 is greater than or equal to the height of the conveyor rollers 14; when the transfer trolley 4 moves on the wheel rail, with the plane where the wheel rail is located as the reference, the height of the bottom of the track wheel 42 is greater than or equal to the height of the bearing seat 13.

[0047] like Figures 4-5 As shown, the upper end of the upper longitudinal beam 111 is also connected to a connecting plate 15. The connecting plate 15 includes an inclined part 151, a vertical part 152 and a transverse part 153 connected in sequence. The inclined part 151 and the vertical part 152 are fixedly connected to the upper longitudinal beam 111; the transverse part 153 and the vertical part 152 are engaged with the edge of the transport vehicle.

[0048] like Figure 6 As shown, the slide assembly also includes an anti-slip mechanism 5, which includes a stop bar seat 51. The stop bar seat 51 is connected to the upper crossbeam 112 or the lower crossbeam 212. The stop bar seat 51 is hinged to a stop bar 52, and a torsion spring 53 is connected between the stop bar 52 and the stop bar seat 51.

[0049] When transferring ammunition box 6, it is first loaded onto the transfer trolley 4 and then securely tied with steel wire rope 5. The traction mechanism uses steel wire rope 5 to pull ammunition box 6, which, together with the transfer trolley 4, ascends along the slide assembly until it reaches the top of the transport vehicle. The stop bar 72 can only bend forward; therefore, in the event that steel wire rope 5 becomes loose or breaks, the descending transfer trolley 4 and ammunition box 6 will be stopped by the stop bar 72.

[0050] When the transfer trolley 4 moves to the top of the upper component 1, the running path arches, creating an obstacle for the transfer trolley 4 to pass through. The rear wheels of the transfer trolley 4 leave the wheel rail, and the bottom of the frame 41 of the transfer trolley 4 rolls into contact with the conveyor roller 14, allowing the transfer trolley 4 to pass through the obstacle smoothly. Example 2

[0051] like Figure 7 As shown, this embodiment differs from Embodiment 1 in that the upper longitudinal beam 111 and the lower longitudinal beam 211 are connected to the two sides of the baffle 8, and the baffle 8 is connected to the baffle plate to further prevent the ammunition box 6 from sliding out of the slide assembly.

[0052] The technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the examples above.
