Abstract
Description
Technical Field
[0001] The invention relates to the technical field of missile military equipment loading and unloading, and in particular to a missile storage and transportation box loading and unloading device. Background Art
[0002] Considering that 5-ton and 10-ton hazardous goods transport trucks are all vans, they cannot be directly loaded with a crane due to the presence of the car roof. When transporting a series of products such as a certain type of missile storage and transportation box, it is difficult to load the storage and transportation box with a van, and it can only be transported with a 13-meter-long trailer, with a transportation cost of 21 yuan / ton / kilometer. If a special loading and unloading device is designed, the product can be loaded onto a 10-ton van-type hazardous goods transport truck, and the cost is 9 yuan / ton / kilometer; if the product is loaded onto a 5-ton van-type hazardous goods transport truck, the cost is 6.5 yuan / ton / kilometer, which greatly reduces the transportation cost. Therefore, it is necessary to design a loading and unloading device that can load the storage and transportation box onto a 5-ton or 10-ton van-type hazardous goods transport truck to meet the requirements of safe, reliable and economic loading and unloading processes. Summary of the invention
[0003] In order to meet the above technical needs, the purpose of the present invention is to provide a missile storage and transportation box loading and unloading device, which fully considers the economic cost of product transportation, safety and convenience during loading and unloading, and can easily realize manual loading and unloading of missile storage and transportation boxes into vans according to the actual conditions of different workshops.
[0004] To solve the above technical problems, the technical solution of the present invention is: a missile storage and transportation box loading and unloading device, comprising a transfer trolley for placing missile storage and transportation boxes, a support frame for facilitating the loading of the transfer trolley, and a winch assembly placed on one side of the support frame and providing power for the transfer trolley; the transfer trolley comprises a transfer support frame and a plurality of universal wheels arranged at the bottom of the transfer support frame, and a lifting eye screw as a fixing point of the wire rope is arranged at the bottom of the transfer support frame; the support frame adopts an inclined support frame or a support platform, the slope of the inclined support frame is set to 3.2°, the support platform is in a horizontal state, and the inclined support frame and the support platform are both provided with a support roller for supporting the wire rope; the winch assembly is arranged on one side of the support frame, comprising a winch bracket and a winch body arranged on the surface of the winch bracket, and two winch fixed pulley groups for threading the wire rope are arranged at the bottom of the winch bracket. When working, the wire rope from the winch body passes through the two winch fixed pulleys, and then is wound around the support roller, and then passes through the lifting eye screw, and the hand-cranked winch body drives the transfer trolley to move.
[0005] Furthermore, the winch body adopts a self-locking worm gear winch VS-500.
[0006] The transfer support frame is welded together with multiple cross beams and longitudinal beams. Handles are welded at both ends of the transfer support frame for easy manual pushing, and lifting eye screws are set at the bottom of the cross beams. The surface of the longitudinal beams is also symmetrically provided with positioning pins for accurate positioning of lifting storage and transportation boxes, and the bottom of the longitudinal beams is provided with multiple transfer auxiliary wheels and adjustable feet.
[0007] The inclined support frame includes a front inclined support and a rear inclined support detachably connected to the front inclined support. The front inclined support and the rear inclined support are both steel frame structures, the bottom is welded by a plurality of steel pipes, a support plate is provided on the top, corner braces are provided on both sides of the support plate for fixing, and support rollers are provided on the surface of the support plate.
[0008] The support platform is a steel frame structure, and a plurality of transport auxiliary wheels and adjustable feet are arranged at the bottom of the support platform, and the support rollers are arranged on the surface of the support platform.
[0009] The winch bracket is a steel frame structure, and a plurality of winch auxiliary wheels are arranged at the bottom of the winch bracket.
[0010] The present invention is composed of a storage and transportation box transfer trolley, an inclined support frame, a winch assembly and a support platform. In order to make the storage and transportation box loading and unloading process flexible and light, a storage and transportation box transfer trolley is designed, which is composed of a transfer support frame and four universal wheels at the bottom. It can carry the storage and transportation box and move flexibly without a crane. Considering the actual situation of a workshop in our factory, the external platform of the workshop is 1.05m high, which is inconsistent with the height of the bottom plate of the dangerous goods transport vehicle compartment, and it is impossible to load directly by pushing the storage and transportation box transfer trolley. After theoretical calculation, an inclined support frame with a reasonable slope is designed to connect the platform and the compartment, and then a worm winch with a wire rope is used to pull the storage and transportation box transfer trolley. At the same time, with the manual control direction, the storage and transportation box with a bracket can be safely and quickly loaded onto a 5-ton or 10-ton van. Finally, the wheels of the storage and transportation box transfer trolley are locked, and the transfer auxiliary wheels are adjusted to support the weight of the box. The storage and transportation box is reliably fixed by using a rope through the locking point inside the compartment. When storage, transportation, shipping and loading and unloading are carried out in a workshop without a platform, there is no need to use an inclined support frame. The height of the support platform can be freely adjusted to accommodate the loading and unloading of 5-ton or 10-ton vans. At the same time, the bottom is equipped with multiple transfer auxiliary wheels to ensure that the support platform is reliably fixed and easy to move.
[0011] The technical problem to be solved by the present invention is that the transportation cost of a certain type of missile storage and transportation box using a large dangerous goods transport vehicle is high, while it is difficult to load and unload on a small dangerous goods transport vehicle. In this regard, a loading and unloading device with a reasonable structure, simple and convenient operation is provided, which can be loaded on a small dangerous goods transport vehicle to reduce transportation costs.
[0012] The beneficial effects of the present invention are as follows: in field tests or when a crane is not available, the transfer trolley can carry the storage and transportation boxes and move them flexibly; the storage and transportation boxes can be safely and conveniently loaded onto a 5-ton or 10-ton small van-type hazardous goods transport vehicle, greatly reducing transportation costs; the present invention can be applied to the storage and transportation box loading and unloading work under different workshop conditions; the cost is low, the processing cycle is short, the assembly is simple, and the operation is convenient.

DETAILED DESCRIPTION
[0019] The specific implementation modes of the present invention are further described in detail below with reference to the accompanying drawings.
[0020] Attached Figure 1-5 An embodiment of the present invention discloses a missile storage, transportation, delivery and loading and unloading device, which is composed of a transfer trolley 1, an inclined support frame 2, a winch assembly 3 and a support platform 4.
[0021] Figure 2The transfer trolley in the figure is composed of a transfer support frame and four universal wheels at the bottom. The transfer support frame adopts a Q235A steel frame structure, which is composed of multiple crossbeams 7 and longitudinal beams 6 to support the weight of the entire storage and transportation box and ensure its rigidity and strength. Handles 10 are welded at both ends of the transfer support frame to facilitate the application of force when manually pushing the trolley. Eye screws 11 are welded at the bottom of the crossbeams 7 located at the two sections of the transfer support frame, which serve as wire rope fixing points and are used in conjunction with the winch assembly 3 during loading and unloading. A universal lifting ring 8 is welded on the surface of the longitudinal beam to facilitate lifting. In addition, four positioning pins 12 are welded on the upper part of the longitudinal beam for accurate positioning when lifting the storage and transportation box. In order to reduce the buffering force, a pine wood pad is used at the contact part of the positioning pin 12 with the box body. In order to facilitate loading and unloading and save time and effort, the four wheels of the transfer trolley are made of high-strength, high-elasticity and wear-resistant transfer auxiliary wheels 13. The wheels are equipped with brakes, with a specification of 5 inches and a rated load of 1.7 tons. The four wheels can withstand the weight of fully loaded storage and transportation boxes. At the same time, four adjustable feet 14 are installed at the bottom of the bracket. When the storage and transportation boxes are placed on the ground and in the transport carriage, the transfer auxiliary wheels 13 can be used to support the weight of the box to avoid long-term stress on the transfer auxiliary wheels 13 to form a safety hazard.
[0022] Due to the inappropriate platform height, in order to adapt to the loading and unloading work of 5-ton or 10-ton van-type dangerous goods transport vehicles, after theoretical calculation, Figure 3 The slope of the inclined support frame is designed to be 3.2°, which includes the front inclined support and the rear inclined support. The inclined support frame is a steel frame structure welded by several steel pipes, and angle braces 17 are welded on the left and right sides of the support plate to fix it. The width of the support plate is 1200mm. The floor of the 5-ton freight car is 1160mm high, and only the front inclined support 15 is needed to connect the platform and the car. The slope length of the front inclined support 15 is 2296mm.
[0023] The height of the floor of a 10-ton truck is 1300mm, so it is necessary to connect a rear oblique bracket 16 to the front oblique bracket 15 to make it flush with the height of the floor of the truck. The total length of the slope of the front and rear oblique brackets is 4677mm. In addition, a support roller 19 for supporting the wire rope is installed on the oblique support frame 2 to cooperate with the winch assembly 3 to make the loading and unloading process more labor-saving.
[0024] Figure 4The winch assembly comprises a winch bracket, a winch body arranged on the winch bracket, a winch fixed pulley group 23, and a winch auxiliary wheel 24. The winch body adopts a worm gear winch VS-500. The winch bracket is a steel frame structure welded by 12 steel pipes. A self-locking worm gear winch VS-500 is installed on the upper part. The load is 500kg, which can fully meet the thrust required for the theoretical calculation of the storage and transportation box to move upward along the inclined support frame; the winch fixed pulley group 23 is fixed at the bottom by two angle braces so that it can pass the wire rope, and the winch auxiliary wheel 24 is installed for adjustment and fixing; the winch assembly is used in conjunction with the inclined support frame and the support platform to make the loading and unloading process more labor-saving.
[0025] like Figure 5 As shown, the bottom of the support platform is welded with a square tube steel frame structure, and the bottom is also provided with an adjustable leg 14 and a transfer auxiliary wheel 24; the adjustable leg adopts a square tube with evenly distributed screw holes, and each leg of the support platform is connected to the adjustable leg through two screws, so that the height of the support platform can be freely adjusted according to different loading and unloading conditions. At the same time, in order to ensure that the support platform is reliably fixed and easy to move, a plurality of transfer auxiliary wheels are provided at the bottom. Support rollers 19 for supporting steel wire ropes are installed at the front and rear ends, and are used in conjunction with the winch assembly 3; the support platform is suitable for storage, transportation, shipping and loading and unloading work in workshops without platforms, and the height can be freely adjusted according to the loading vehicle.
[0026] The specific process of the present invention in use is as follows: When loading a missile storage and transportation box onto a 5-ton van in a workshop of our factory, first lock the wheels of the transfer trolley 1, and use a crane to lift the storage and transportation box 5 onto the transfer trolley 1; then place the front oblique bracket 15 on the platform to make it flush with the height of the bottom plate of the 5-ton van; manually push the transfer trolley 1 onto the front oblique bracket 15; then pass the wire rope on the worm gear winch VS-500 through the two capstan fixed pulley blocks 23 below, wind it around the supporting roller above the front oblique bracket 15, and connect and fix it with the lifting eye screw 11 at the rear end of the transfer trolley; the hand-cranked worm gear winch VS-500 pulls the storage and transportation box transfer trolley, and at the same time cooperates with manual control of the direction to load the storage and transportation box onto the 5-ton van safely and quickly; finally, lock the wheels of the storage and transportation box transfer trolley, adjust the adjustable feet 14 and the transfer auxiliary wheels 13 to support the weight of the box, and then use the rope to pass through the locking points inside the car to reliably fix the storage and transportation box.
[0027] If the storage and transportation box is to be loaded onto a 10-ton van, it is only necessary to connect a rear oblique bracket 16 to the front oblique bracket 15 so that it is flush with the bottom plate of the 10-ton van, and the remaining steps are the same as those for loading a 5-ton van. The unloading operation is the opposite.
[0028] When loading storage and transportation boxes in a workshop without a platform, there is no need to use an inclined support frame, and a support platform with auxiliary transfer wheels and adjustable height is required. First, adjust the adjustable feet to make the height of the support platform flush with the floor of the 5-ton or 10-ton van, then use the overhead crane to lift the storage and transportation box transfer trolley 1 to the support platform 4, pass the wire rope on the hand-cranked worm winch VS-500 around the support roller 19 behind the support platform, and connect and fix it with the eye screw 11 at the rear end of the storage and transportation box transfer trolley, then manually push the support platform 4 to the carriage, and finally use the hand-cranked worm winch VS-500 to pull the storage and transportation box into the carriage. The unloading operation is the opposite.
[0029] The above shows and describes the basic principles and main features of the present invention. The slope of the inclined bracket, the pulling force required for the box storage and transportation transfer trolley during loading and unloading, and the selection of the specifications of the worm winch in the present invention have all been theoretically calculated and verified by experiments. The channel steel, lifting ring, winch, etc. used are all standard parts and can be purchased in the market. The specific connection methods of each part all adopt conventional means such as mature bolts and welding in the prior art, and the machinery, parts and equipment all adopt conventional models in the prior art.
