Description

Technical Field

[0001] This utility model belongs to the field of military equipment technology, specifically a hoisting frame for loading oil depot equipment. Background Technology

[0002] Field oil depots are mobile oil depots temporarily set up behind the lines of a campaign to ensure the timely supply of oil to troops. They are used to store the oil and fuel equipment needed by the troops. Field oil depots are a very large system, containing many subsystems and equipment that can be quickly disassembled and assembled.

[0003] When constructing an outdoor oil depot, equipment needs to be lifted using lifting equipment. This requires the use of a lifting frame to hold and secure the oil depot equipment. Traditional lifting methods include binding and box-type. The binding method uses binding straps to secure the equipment to be lifted before lifting it. However, the binding method has problems such as difficulty in binding and the equipment being prone to loosening after binding. The box-type method uses cargo boxes to store the equipment to be lifted, which are then loaded into the boxes before lifting the boxes. However, the box-type lifting method has problems such as the large weight of the boxes and the inconvenience of stacking the equipment.

[0004] Therefore, this utility model provides a lifting frame for loading oil depot equipment. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background technology, such as the difficulty in binding and the ease with which the binding is loose, as well as the problems of the large weight of the box and the inconvenience of stacking equipment in the box-type hoisting, a hoisting frame for loading oil depot equipment is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The lifting frame for loading oil depot equipment according to this utility model includes a bottom pallet, two sets of side frames fixed to the top of the bottom pallet, a back frame fixed to the top of the bottom pallet, the back frame and the two sets of side frames being fixedly connected, a lower flexible strap installed at the bottom of the back frame, a ratchet tightener fixed to the end of the lower flexible strap, an upper flexible strap installed at the top of the back frame, and a clamping assembly provided on the back frame. Through the above structure, the overall lifting frame can be made lighter, and at the same time has the characteristics of convenient loading and unloading, firm and reliable, and high flexibility, improving the convenience of stacking and unloading equipment.

[0007] Preferably, the clamping assembly includes a guide rail fixed to the middle of the back frame. A bidirectional lead screw is rotatably connected inside the guide rail. A pair of sliders are threaded onto the bidirectional lead screw. A clamping plate is fixed to the side wall of the slider. A hand crank is fixed to the end of the bidirectional lead screw. Through the above structure, the clamping plate clamps and fixes the two sides of the device. Combined with the lower flexible strap, ratchet tightener, and upper flexible strap for longitudinal fixation of the device, the fixing effect of the device can be improved, making the device more stable.

[0008] Preferably, multiple corner reinforcement plates are fixedly connected at the connection between the bottom tray and the side frame and the back frame. The corner reinforcement plates are provided with lifting holes. Through the above structure, the corner reinforcement plates can reinforce the connection between the bottom tray and the side frame and the back frame, and improve the stability of the connection between the bottom tray and the side frame and the back frame. The lifting holes can facilitate the connection between the lifting equipment and the lifting frame.

[0009] Preferably, a pair of winding posts are fixedly connected to the side wall of the side frame, and a plug is fixedly connected to the end of the winding post. With the above structure, the lower flexible strap is wrapped around the winding post, which can reduce the situation where the lower flexible strap drags on the ground when placed, causing the lower flexible strap to be scratched and damaged by the ratchet tightener.

[0010] Preferably, a pull ring is fixedly connected to the ratchet tightener, and a guard is fixedly connected to the pull ring. Through the above structure, the pull ring and the guard can provide a position for applying force when operating the ratchet tightener, thereby improving the convenience of lifting and pressing down the ratchet tightener.

[0011] Preferably, a rubber pad is installed on the side wall of the clamping plate. The rubber pad is made of a flexible material. Through the above structure, the flexible material of the rubber pad can reduce the damage caused by the clamping plate squeezing the surface of the equipment.

[0012] Preferably, the lower flexible strap and the upper flexible strap can be made of polyester or nylon. Through the above structure, polyester or nylon has the characteristics of high strength, strong wear resistance and corrosion resistance, thereby improving the overall performance of the lower flexible strap and the upper flexible strap.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The lifting frame for loading oil depot equipment described in this utility model can make the overall lifting frame lighter, while having the characteristics of convenient loading and unloading, sturdiness and reliability, and high flexibility, thereby improving the convenience of stacking and unloading equipment.

[0015] 2.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Specific implementation examples are given below.

[0026] like Figures 1 to 4As shown in the embodiment of this utility model, a lifting frame for loading oil depot equipment includes a base tray 1. Two sets of side frames 11 are fixedly connected to the top of the base tray 1, and a back frame 12 is fixedly connected to the top of the base tray 1. The back frame 12 is fixedly connected to the two sets of side frames 11. A lower flexible strap 13 is installed at the bottom of the back frame 12, and a ratchet tightener 14 is fixedly connected to the end of the lower flexible strap 13. An upper flexible strap 15 is installed at the top of the back frame 12. A clamping assembly is provided on the back frame 12. During operation, the ratchet tightener 14 is opened, and then the ratchet... The connection between the tensioner 14 and the upper flexible strap 15 is opened. Then, the oil depot equipment to be hoisted is placed on top of the bottom pallet 1, and the bottom of the equipment is pressed against the lower flexible strap 13. Then, the upper flexible strap 15 is wrapped around the top of the equipment, and the upper flexible strap 15 is connected to the ratchet tensioner 14. The ratchet tensioner 14 is used to tighten the lower flexible strap 13 and the upper flexible strap 15 to fix the equipment. Through the above structure, the overall hoisting frame can be made lighter, and at the same time, it has the characteristics of convenient loading and unloading, sturdiness and reliability, and high flexibility, which improves the convenience of stacking and unloading equipment.

[0027] like Figure 1 and Figure 3 As shown, the clamping assembly includes a guide rail 2, which is fixedly connected to the middle of the back frame 12. A bidirectional lead screw 21 is rotatably connected inside the guide rail 2. A pair of sliders 22 are threaded onto the bidirectional lead screw 21. Clamping plates 23 are fixedly connected to the side walls of the sliders 22. A hand crank 24 is fixedly connected to the end of the bidirectional lead screw 21. During operation, rotating the hand crank 24 drives the bidirectional lead screw 21 to rotate. At this time, the bidirectional lead screw 21 will drive the sliders 22 to slide relative to each other inside the guide rail 2. The sliders 22 will drive the clamping plates 23 to move closer or further apart. When the size of the equipment is different, the rotation direction of the hand crank 24 can be controlled to clamp the clamping plates 23 on both sides of the equipment. Through the above structure, the clamping plates 23 clamp and fix the two sides of the equipment. Combined with the lower flexible strap 13, ratchet tightener 14, and upper flexible strap 15 for longitudinal fixation of the equipment, the fixing effect of the equipment can be improved, making the equipment more stable.

[0028] like Figure 2 As shown, multiple corner reinforcement plates 3 are fixedly connected to the connection between the bottom tray 1 and the side frame 11 and the back frame 12. The corner reinforcement plates 3 are provided with lifting holes 31. During operation, the lifting holes 31 are made on the corner reinforcement plates 3 using a hole saw. Then, multiple sets of corner reinforcement plates 3 are fixed to the corner connection between the bottom tray 1 and the side frame 11 and the back frame 12 by welding. Through the above structure, the corner reinforcement plates 3 can reinforce the connection between the bottom tray 1 and the side frame 11 and the back frame 12, and improve the stability of the connection between the bottom tray 1 and the side frame 11 and the back frame 12. The lifting holes 31 can facilitate the connection between the lifting equipment and the lifting frame.

[0029] like Figure 2 As shown, a pair of winding posts 4 are fixed to the side wall of the side frame 11. A plug 41 is fixed to the end of the winding post 4. During operation, after use, a portion of the lower flexible strap 13 can be wrapped around the winding posts 4 on both sides. When it is needed for reuse, the lower flexible strap 13 can be untied from the winding post 4. Through the above structure, the lower flexible strap 13 is wrapped around the winding post 4, which can reduce the lower flexible strap 13 from dragging on the ground when placed, thus reducing the possibility of the lower flexible strap 13 being scratched or damaged by the ratchet tightener 14.

[0030] like Figure 4 As shown, a pull ring 5 is fixedly connected to the ratchet tightener 14, and a handguard 51 is fixedly connected to the pull ring 5. During operation, when using the ratchet tightener 14 to tighten the upper flexible strap 15, the operator can hold the handguard 51 and then continuously lift and press down the pull ring 5 and the handguard 51 to drive the ratchet tightener 14 to tighten the upper flexible strap 15. Through the above structure, the pull ring 5 and the handguard 51 can provide a position for applying force when operating the ratchet tightener 14, thereby improving the convenience when lifting and pressing down the ratchet tightener 14.

[0031] like Figure 5 As shown, a rubber pad 6 is installed on the side wall of the clamping plate 23. The rubber pad 6 is made of flexible material. During operation, when the clamping plate 23 clamps and fixes the two sides of the equipment, the rubber pad 6 will come into contact with the two sides of the equipment. Through the above structure, the flexible material of the rubber pad 6 can reduce the damage caused by the clamping plate 23 squeezing the surface of the equipment.

[0032] like Figure 2 As shown, the lower flexible strap 13 and the upper flexible strap 15 can be made of polyester or nylon. Through the above structure, the polyester or nylon material has the characteristics of high strength, strong wear resistance and corrosion resistance, thereby improving the overall performance of the lower flexible strap 13 and the upper flexible strap 15.

[0033] Working principle: Open the ratchet tightener 14 and then disconnect the ratchet tightener 14 from the upper flexible strap 15. Place the oil depot equipment to be hoisted on top of the bottom pallet 1, and press the bottom of the equipment against the lower flexible strap 13. Then, wrap the upper flexible strap 15 around the top of the equipment and connect it to the ratchet tightener 14. Use the ratchet tightener 14 to tighten the lower flexible strap 13 and the upper flexible strap 15 to fix the equipment. Rotate the hand crank 24 to drive the double-acting screw 21 to rotate. At this time, the double-acting screw 21 will drive the slider 22 to slide relative to each other in the guide rail 2. The slider 22 will drive the clamping plates 23 to move closer or further apart. When the size of the equipment is different, the rotation direction of the hand crank 24 can be controlled to achieve the desired effect. Clamping plates 23 are placed on both sides of the equipment. Hoisting holes 31 are made on the corner joint reinforcing plates 3 using a hole saw. Then, multiple sets of corner joint reinforcing plates 3 are fixed to the corner joints of the bottom tray 1, side frame 11, and back frame 12 by welding. After use, a portion of the lower flexible strap 13 can be wrapped around the winding posts 4 on both sides. When it is needed for reuse, the lower flexible strap 13 is untied from the winding posts 4. When using the ratchet tightener 14 to tighten the upper flexible strap 15, the operator can hold the handguard 51 and continuously lift and press the pull ring 5 and the handguard 51 to drive the ratchet tightener 14 to tighten the upper flexible strap 15. When clamping plates 23 clamp and fix the sides of the equipment, the rubber pads 6 will contact the sides of the equipment.
