Technical Field
[0001] This utility model belongs to the field of airdrop of supplies, specifically involving an integrated fuel bladder airdrop fixing frame. Background Technology
[0002] In the airdrop of supplies, the airdrop of fuel bladders is quite special because the airdropped fuel bladder is a cylindrical object, and there is nowhere to attach it. After being filled with fuel, the weight of the fuel bladder is generally in the tons, so the requirements for fixation are high. Therefore, it is often necessary to set up a fixing frame, put the fuel bladder into the fixing frame and fix it, so that the fixing frame and the fuel bladder are airdropped together.
[0003] Currently, there is no standardized method for airdropping fuel bladders. Furthermore, there are difficulties in securing the fuel bladders, making them difficult to detach efficiently after landing, and sometimes requiring mechanical assistance. The overall integrity is poor, making it impossible to transport them in a unified manner, which greatly affects combat efficiency.
[0004] How to provide an integrated fuel bladder airdrop mounting frame that allows staff to easily and quickly load and unload fuel bladders is a technical problem that urgently needs to be solved. Utility Model Content
[0005] This utility model provides an integrated oil bladder airdrop fixing frame to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated fuel bladder airdrop mounting frame includes a box-type frame with an open top and a fuel bladder positioning mechanism located at the bottom of the box-type frame. The box-type frame includes a base frame, a front upright, a rear upright, a left upright, and a right upright arranged around the base frame. The front upright serves as an openable and closable gate for the box-type frame. The bottom of the front upright is hinged to the bottom front end of the box-type frame, or one side of the front upright is hinged to one side of the front end of the box-type frame. The fuel bladder positioning mechanism includes a rear positioning mechanism fixed to the base frame and a front positioning mechanism slidably arranged on the base frame. The rear positioning mechanism includes at least one rear positioning unit, and the front positioning mechanism includes at least one front positioning unit. Both the rear and front positioning units have an arc-shaped support surface adapted to the side of the fuel bladder. The vertical projection of the fuel bladder axis is located on the arc-shaped surface of the rear positioning mechanism.
[0007] Preferably, both the rear positioning unit and the front positioning unit are strip-shaped high-density EVA foam blocks or strip-shaped foam blocks with arc-shaped support surfaces. The cross-section of the strip-shaped high-density EVA foam blocks or strip-shaped foam blocks is a pattern formed by horizontal sides, vertical sides, and arc-shaped sides connecting the horizontal and vertical sides.
[0008] Preferably, both the rear positioning unit and the front positioning unit include at least two longitudinally arranged vertical support plates and an arc-shaped plate fixed on the support plates that is adapted to the side of the oil bladder, wherein the upper surface of the arc-shaped plate is an arc-shaped surface.
[0009] Preferably, the bottom of the front upright is hinged to the bottom of the left and right uprights to achieve the hinged connection of the bottom of the front upright at the bottom of the front end of the box frame.
[0010] Preferably, the front positioning mechanism is provided with three front positioning units, the vertical support plates of the front positioning units are two end vertical support plates, and the base frame is provided with multiple guide strips that cooperate with the outer side of the end vertical support plates.
[0011] Preferably, the top four corners of the box-type frame have lifting lugs with lifting holes, the front end faces of the left and right uprights are provided with horizontal locking sleeves, and the width of the front upright is less than or equal to the distance between the left and right uprights.
[0012] Preferably, the front end face of the front stand is provided with a positioning sleeve that engages with the locking sleeve.
[0013] Preferably, a longitudinally fixed connecting rod is provided on the vertical support plate of each of the front positioning units.
[0014] Preferably, the back of the arc-shaped plate is provided with at least one reinforcing rib in the longitudinal direction, and the support plate has a groove for the reinforcing rib to pass through.
[0015] This utility model discloses an integrated fuel bladder airdrop mounting frame, comprising a box-shaped frame with an open top and a fuel bladder positioning mechanism located at the bottom inside the box-shaped frame. The front upright can be opened from the box-shaped frame. The fuel bladder positioning mechanism is ingeniously designed, supporting and partially enclosing the fuel bladder from below. The arc-shaped plate of the rear positioning mechanism provides vertical support for the fuel bladder, while the arc-shaped plate of the front positioning mechanism limits the fuel bladder's position. Since the front positioning mechanism is slidably mounted on the base frame, when removing the fuel bladder from the box-shaped frame after opening the front upright, the front positioning mechanism is pulled forward, and then the fuel bladder is pushed to roll out of the box-shaped frame. Because the arc-shaped plate of the rear positioning mechanism bears the pressure of the fuel bladder and has a certain curvature, it can limit the rolling of the fuel bladder to a certain extent, making it relatively easy to pull the front positioning mechanism forward. At the same time, the fuel bladder can remain stable during the pulling out of the front positioning mechanism. When loading the fuel bladder, the fuel bladder is rolled onto the rear positioning mechanism, then the front positioning mechanism is inserted to limit the fuel bladder's position. Finally, the front upright is closed and the fuel bladder and box-shaped frame are secured.
[0016] Furthermore, the addition of guide bars provides guidance and longitudinal limiting during the movement of the front positioning mechanism into and out of the chassis.
[0017] Furthermore, the top four corners of the box-type frame have lifting lugs with lifting holes for easy hoisting and parachute hooking. Horizontal locking sleeves are set on the front end face of the left and right uprights. The width of the front upright is less than or equal to the distance between the left and right uprights, so that the front upright is located between the left and right uprights when closed. The front end face of the front upright is provided with a positioning sleeve that locks and cooperates with the locking sleeve. The locking sleeve and the positioning sleeve are inserted into the locking steel bar to lock the front upright.
[0018] Furthermore, a connecting rod is inserted longitudinally into the support plate, making it very convenient to grab the connecting rod when pulling out or inserting the front positioning mechanism. At the same time, the connecting rod enhances the structural strength of the front positioning mechanism.
[0019] Furthermore, at least one reinforcing rib is longitudinally provided on the back of the curved plate, and the support plate has a groove for the reinforcing rib to pass through, which further enhances the structural strength of the front positioning mechanism. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that the following detailed description is illustrative and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0023] An embodiment of the integrated fuel bladder airdrop mounting frame, such as... Figure 1 , Figure 2As shown, the device includes a box-type frame with an open top and an oil bladder positioning mechanism located at the bottom of the box-type frame's interior. The box-type frame includes a base frame 10, a front upright 6, a rear upright 12, a left upright 11, and a right upright 1 arranged around the base frame. Each upright and the base frame is made of square tubing and can be a rectangular grid structure with diagonal ribs or a star-shaped structure, etc., which is existing technology. Each of the four corners of the box-type frame has a column shared by adjacent uprights, and the lower end of the column extends downward to support the legs. The front upright serves as an openable and closable gate for the box-type frame. The bottom of the front upright is hinged to the bottom of the front of the box-type frame or one side of the front upright is hinged to one side of the front of the box-type frame. In this embodiment, the bottom of the front upright is hinged to the bottom of the left and right uprights to achieve a hinged connection between the bottom of the front upright and the bottom of the front of the box-type frame. The oil bladder positioning mechanism includes a rear positioning mechanism fixed on the base frame and a front positioning mechanism slidably mounted on the base frame. The rear positioning mechanism includes at least one rear positioning unit, and the front positioning mechanism includes at least one front positioning unit. In this embodiment, the rear positioning mechanism includes one rear positioning unit. In other embodiments, two or more can be provided as needed. The front positioning mechanism includes three front positioning units. Both the rear and front positioning units have arc-shaped support surfaces adapted to the side of the oil bladder. The vertical projection of the oil bladder axis is located on the arc-shaped surface of the rear positioning mechanism. Specifically, both the rear and front positioning units include at least two longitudinally arranged vertical support plates 5, 8, 14, and 15, and arc-shaped plates 2 and 9 fixed on the support plates to adapt to the side of the oil bladder. The upper surface of the arc-shaped plate is an arc-shaped surface, and the vertical projection of the oil bladder axis is located on the arc-shaped plate 9 of the rear positioning mechanism. In simple terms, when the upper surfaces of the arc-shaped plates of the front and rear positioning mechanisms are on the same horizontal plane, the width of the arc-shaped plate of the rear positioning mechanism is greater than that of the arc-shaped plate of the front positioning mechanism. Specifically, the vertical support plates 5 and 8 of the front positioning unit are two end vertical support plates, and multiple guide strips 7 are provided on the base frame to cooperate with the outer side of the end vertical support plates. A longitudinal connecting rod 4 is fixed on the vertical support plate of each front positioning unit. At least one reinforcing rib 3 is longitudinally provided on the back of the arc-shaped plate, and the support plate has a groove for the reinforcing rib to pass through.
[0024] The box-type frame has lifting lugs 16 with lifting holes at its four top corners. Horizontal locking sleeves 17 are provided on the front end faces of the left and right uprights. The width of the front upright is less than or equal to the distance between the left and right uprights. A positioning sleeve (not shown in the figure) is provided on the front end face of the front upright to lock into the locking sleeve.
[0025] This embodiment of the integrated fuel bladder airdrop mounting frame includes a box-shaped frame with an open top and a fuel bladder positioning mechanism located at the bottom inside the box-shaped frame. The front upright can be opened from the box-shaped frame. The fuel bladder positioning mechanism is ingeniously designed, supporting and partially enclosing the fuel bladder 13 from the bottom. The arc-shaped plate of the rear positioning mechanism provides vertical support for the fuel bladder, while the arc-shaped plate of the front positioning mechanism limits the fuel bladder's position. Since the front positioning mechanism is slidably mounted on the base frame, when the fuel bladder is removed from the box-shaped frame after the front upright is opened, the front positioning mechanism is pulled forward, and then the fuel bladder is pushed to roll out of the box-shaped frame. Because the arc-shaped plate of the rear positioning mechanism bears the pressure of the fuel bladder and has a certain curvature, it can limit the rolling of the fuel bladder to a certain extent, making it relatively easy to pull the front positioning mechanism forward. At the same time, the fuel bladder can remain stable during the pulling out of the front positioning mechanism. When loading the fuel bladder, the fuel bladder is rolled onto the rear positioning mechanism, and then the front positioning mechanism is inserted to limit the fuel bladder's position. Finally, the front upright is closed and the fuel bladder and box-shaped frame are fixed.
[0026] This embodiment features guide strips that provide guidance and longitudinal restraint during the movement of the front positioning mechanism into and out of the base frame. The top four corners of the box-type frame have lifting lugs with hoisting holes for easy hoisting and parachute hooking. Horizontal locking sleeves are installed on the front ends of the left and right uprights. The width of the front upright is less than or equal to the distance between the left and right uprights, ensuring that the front upright, when closed, lies between the left and right uprights. A positioning sleeve, which engages with the locking sleeves, is located on the front end of the front upright. The locking sleeve and positioning sleeve are inserted into locking reinforcing bars to lock the front upright. A connecting rod is longitudinally inserted into the support plate. Pulling out and inserting the front positioning mechanism is very convenient, and the connecting rod also enhances the structural strength of the front positioning mechanism. At least one reinforcing rib is longitudinally installed on the back of the curved plate, and the support plate has grooves for the reinforcing rib to pass through, further enhancing the structural strength of the front positioning mechanism.
[0027] In other embodiments, unlike the embodiments described above, the front positioning mechanism is a front positioning unit. The vertical support plate includes end vertical support plates at both ends and two sets of vertical support plates in the middle. Each set of vertical support plates includes two parallel vertical support plates arranged at intervals and forming a guide slot. The base frame is provided with two end guide strips 7 that cooperate with the outer side of the end vertical support plates and a middle guide strip (not shown in the figure) that cooperates with the guide slot. The connecting rod is inserted into the two sets of vertical support plates in the middle and fixed at both ends to the end vertical support plates.
[0028] In other embodiments, unlike the embodiments described above, both the rear positioning unit and the front positioning unit are strip-shaped high-density EVA foam blocks or strip-shaped foam blocks with arc-shaped support surfaces. The cross-section of the strip-shaped high-density EVA foam blocks or strip-shaped foam blocks is a pattern formed by horizontal sides, vertical sides, and arc-shaped sides connecting the horizontal and vertical sides.
