Description

Technical Field

[0001] The invention belongs to the field of armored vehicles and relates to a lightning protection lifting platform for armored vehicles. Background Art

[0002] Due to structural limitations, armored vehicles have become increasingly thinner, and their overall strength is slightly weak. After being impacted, the space between the top deck and the top deck is easily squeezed and compressed, and the strength of this area needs to be enhanced. In order to meet the requirement of lifting the operator to a certain height to facilitate other operations within a limited space, a platform mechanism is needed that can both increase the local strength of the armored vehicle and provide a stable and controllable lifting and lowering platform.

[0003] The existing lifting mechanism is generally arranged as follows: a fixed seat is welded on the bottom deck, and the lifting mechanism is installed on the fixed seat.

[0004] The existing lifting mechanism is fixed on the bottom deck and is not connected to the top deck structure, so the strength of this part cannot be enhanced. When the armored vehicle is impacted by an explosion such as a mine, the impact force is directly transmitted to the lifting structure through the bottom deck, causing a high instantaneous acceleration for the personnel or important items on the lifting mechanism. It is necessary to eliminate or reduce the instantaneous acceleration to a safe range to ensure the safety of the personnel or important items. Summary of the invention

[0005] The purpose of the present invention is to provide a lightning-proof lifting platform for armored vehicles. The fixed columns of the lightning-proof lifting platform are installed between the top deck and the bottom deck, supporting the top deck and strengthening the strength of the armored vehicle. The lightning-proof sleeves on both sides of the lightning-proof lifting platform are equipped with energy-absorbing devices, and the bottom deck absorbs the impact energy of explosive energy such as mines, thereby reducing the impact received by the lightning-proof lifting platform. At the same time, the gas springs on both sides can slow down the instantaneous acceleration of the impact force on the controllable lifting platform, thereby protecting the safety of personnel and important items on the lightning-proof lifting platform.

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0043] like Figures 1 to 11 As shown, the lightning protection lifting platform provided by the present invention is mainly composed of two column assemblies (1), two lightning protection sleeves (2), two gas springs (3), a lifting control system (4), a frame platform (5), a right support arm (6) and a left support arm (7).

[0044] The column assembly is mainly composed of an upper column (8) and a lower column (9). The upper end of the upper column (8) is a square end, the middle part is evenly distributed with a number of limit holes from top to bottom, and the lower end is a stud. The upper end of the lower column (9) is provided with a threaded hole, the middle part is provided with a slot for adjustment, and the lower end is a round end. The adjustment slot is rotated to adjust the length of the stud at the lower end of the upper column (8) entering the threaded hole at the upper end of the lower column (9), thereby adjusting the overall length of the column assembly.

[0045] The two column assemblies are symmetrically installed between the top deck and the bottom deck, and the rotation adjustment slots allow the two column assemblies to be firmly supported between the top deck and the bottom deck, thereby enhancing the local strength of the armored vehicle at that location.

[0046] like Figure 3 As shown, the lightning protection mechanism mainly consists of a lightning protection sleeve (2), a lightning protection ring, a left support arm (7) and a hanging part of a right support arm (6).

[0047] The lightning protection sleeve (2) is integrally formed of a cylindrical structure and a hanging structure located on one side thereof. A mounting hole is arranged on the lightning protection sleeve (2), and the cylindrical structure is sleeved on the upper column (8) and fixedly mounted through the mounting hole.

[0060] A lower latch (19) and an upper latch (23) are welded at both ends of the brake wire. The lower latch (19) is installed in a connecting hole at the lower end of the slider (13), and the upper latch (23) is installed in a connecting hole of a limit latch (24) located in the fixing seat (21).

[0061] Nuts (20) are installed on both sides of the fixing plate 18 to fix the brake wires.

[0062] The fixing seat (21) is fixed to the upper end of the cylindrical structure of the lightning protection sleeve by bolts. Figure 3 As shown, the limit pin (24) is inserted into the limit hole at the upper end of the upper column 8 of the column assembly (1).

[0063] The spring (22) is installed in the inner cavity of the fixing seat (21) and is located on the left side of the limiting latch (24) for resetting the limiting latch (24).

At the same time, pull the lower latch 19 of the gate line to make the fixing seat (21) at the other end escape from the upper limit hole of the column assembly (1), and the lightning protection sleeve (2) slides up and down on the column assembly (1) under the push of the synchronous gas spring (3). When it is adjusted to a suitable position, release the lifting handle, and the fixing seat (21) is inserted into the limit hole on the upper column of the column assembly (1) to complete the lifting control process.

[0069] The controllable lifting platform has the following key points:

[0071] 2. Lifting control mechanism and principle. The rotary displacement is converted into linear displacement, which solves the problem of simultaneous extension and retraction of two brake wires.

[0072] 3. Gate wire structure. After the gate wire is fixed, the spring end is pressed into the upper end of the lightning protection sleeve and fixed to the lightning protection sleeve with bolts. The structure is compact and reasonable, providing technical reserves for subsequent gate wire design.

[0073] 4. The frame platform is mounted on the column assembly through the left and right arms, which prevents the explosion impact of mines and other explosives from being directly transmitted from the bottom deck to the frame platform, causing damage to personnel or important items on the frame platform. At the same time, the column assembly is installed between the top deck and the bottom deck, supporting the top deck and strengthening the local strength.
