Therefore, the combination of the 'sets' can exert the battle power and off-road power of the tank to the maximum extent.

The invention aims to greatly improve the super-strong obstacle-crossing self-rescue capacity of the tank in the battle action. When a hidden target needs to be dispersed, the snake-shaped tank can be quickly divided into various tank units 1 for action; when a single tank encounters obstacles which cannot be crossed or needs to be intensively combined to deal with complex terrains, the snake-shaped tank can be quickly combined to move. In the design structure, only a modern tank needs to be slightly changed, and a set of simplified hydraulic swing mechanism is additionally arranged, so that the tank can be put into application. The invention aims to design a snake-shaped tank which is strong and durable, low in cost, simple in structure and quick in action.

When a single tank encounters an obstacle which cannot be crossed or easily collapsed terrain which cannot be moved and complex terrain in military operation, a plurality of tanks are needed to be combined and butted to form a snake-shaped tank to move, and the butt joint work of the snake-shaped tank is divided into three steps:

1. the position of putting is as shown in figure 1, and two tank units 1 of preparation butt joint are opened to relatively flat subaerial in tandem respectively, drive the tank track through the tank drive wheel and carry out the correcting position, let the tank shirt rim or the central line of two tanks arrange into a straight line as far as possible can, and at this moment, the position work of putting of two butt joint tanks is ready to finish, will carry out next butt joint procedure.

2. The front part of each tank unit for placing the butt hook is provided with a front butt hook beam 2, after the two tank units 1 are in a correct position, at the moment, the tank unit 1 at the rear side is locked with a first clutch sleeve bayonet lock 48 and a second clutch sleeve bayonet lock 49, so that a first clutch sleeve 46 and a second clutch sleeve 47 are respectively connected with the left swing hydraulic cylinder 42, and the shaft of the right swing hydraulic cylinder 43 is in a closed state, namely, the front butt hook beam is rigidly connected. At this time, the left swing hydraulic cylinder 42 and the right swing hydraulic cylinder 43 can control the rotation of the hook beam shaft 41 together, and drive the front butt hook beam 2 to swing up and down. After the first clutch sleeve bayonet lock 48 and the second clutch sleeve bayonet lock 49 are locked, the left swing hydraulic cylinder 42 is started to connect and the right swing hydraulic cylinder 43 starts to work, and the hook beam shaft 41 and the front butt hook beam 2 are rigidly connected into a whole, so the front butt hook beam 2 at the front end of the tank unit 1 at the rear side is rotated forwards along the direction of an arc arrow and swung out until the front butt hook beam 2 is in a linear horizontal state, and at the moment, the left swing hydraulic cylinder 42 is connected and the right swing hydraulic cylinder 43 stops working, the front butt hook beam 2 of the tank unit 1 at the rear side is put away and waits for butt joint. Meanwhile, a vertical U-shaped rear butt hook opening 3 is provided below the secondary fuel tank 6 of the tank unit 1, and the third clutch sleeve pin 57 is locked to bring the third clutch sleeve 56 into engagement with the shaft of the vertical swing hydraulic cylinder 53, that is, into rigid connection. The rear butt hook opening 3 can freely swing left and right along the axis of the second bearing 54. After the third clutch sleeve bayonet 57 is locked, the vertical swing hydraulic cylinder 53 is started to start working, and the elliptic conical hook opening of the rear butt hook opening 3 of the tank unit 1 on the front side is aligned with the elliptic conical hook tip of the front butt hook beam 2 of the tank unit 1 on the rear side. By this point, the operation procedure of putting butt hooks of the two tank units 1 is completed, and the next operation procedure is to be entered.

3. Drive docking when the rear docking hook ports 3 of two tank units 1 are aligned with the front docking hook beam 2, drive docking can be prepared. The tank unit 1 on the front side is operated to reverse in the direction of the arrow in FIG. 1 to complete docking, and the tank unit 1 on the rear side is operated to advance in the direction of the arrow to complete docking. Under the drive of tank self power, the oval conical hook point of butt joint hook roof beam 2 in the front slowly gets into in the oval conical hook mouth of butt joint hook mouth 3 behind, because oval conical has the effect of direction, so uneven ground or the position just can not influence the tank butt joint in certain extent. When the tank is driven by itself to move forward or backward, and the two bayonets 21 on both sides of the front butt hook beam 2 are aligned with the wedge-shaped bayonet 31 on the rear butt hook mouth 3, the wedge-shaped bayonet 31 automatically pops up and locks the front butt hook beam 2 under the elastic force of the spring 32, so that the front butt hook beam 2 and the rear butt hook mouth 3 are rigidly butted together. So far, the two tank units 1 drive the docking operation procedure to be finished. The docking method of any other tank unit 1 is the same, and when five tanks are docked, the snake tanks are assembled.

The basic actions of obstacle-crossing self rescue of the snake-shaped tank are head raising, head lowering, creeping, swimming, side shifting, tail bending, tail ending, advancing, retreating, turning and the like. In military operations, obstacles that snakelike tanks can cross and self-rescue conditions mainly have the following types:

1. slope as shown in fig. 6, when a snake-shaped tank encounters a slope of any angle within 90 degrees, the tank can advance under the thrust of five tanks, and the left swing hydraulic cylinder 42 and the right swing hydraulic cylinder 43 are actuated to control different upward and downward swing angles of the tank in the middle. When the tank inducer of the first tank unit 1 contacts with a slope, a left swinging hydraulic cylinder 42 and a right swinging hydraulic cylinder 43 are started to rotate upwards, the head of the first tank unit 1 is lifted, namely, the head raising action of the snake-shaped tank is completed, the first tank unit 1 completely ascends the slope to continue to advance, when the front inducer of the second tank unit 1 contacts with the slope, a left swinging hydraulic cylinder 42 and a right swinging hydraulic cylinder 43 of a third tank unit 1 are started to swing upwards, the slope of the body of the second tank unit 1 is lifted, meanwhile, a left swinging hydraulic cylinder 42 and a right swinging hydraulic cylinder 43 of the second tank unit 1 are also started to swing downwards, namely, the head lowering action of the snake-shaped tank is completed, the tank track of the first tank unit 1 is closely attached to the slope to continue to advance, when the body of the first tank unit 1 passes over the highest point of the slope, a left swinging hydraulic cylinder 42 and a right swinging hydraulic cylinder 43 of the second tank unit 1 are started to swing downwards, the tank track of the left swinging hydraulic cylinder 42 and the right swinging hydraulic cylinder 43 is closely attached to the horizontal direction to continue to advance forwards, the tank unit 1, and the fifth tank unit 1 repeats the tank unit. And finally all the tank units 1 climb through the climbing slope under the combined action of pulling forward and pushing backward to complete the obstacle crossing of the slope.

2. Vertical wall and the obstacle of falling trapezoidal form are as shown in fig. 7-8, and when snakelike tank meets vertical wall or the obstacle of falling trapezoidal form, snakelike tank will be stopped at a suitable position at first to prevent that the headstock of first tank unit 1 touches vertical wall or the obstacle of falling trapezoidal form and damages the tank when doing the action of raising the head. After the snake-shaped tank stops, a left swinging hydraulic cylinder 42 and a right swinging hydraulic cylinder 43 of a second tank unit 1 or a third tank unit 1 are started to lift up a first tank unit 1 or two tanks of the first tank unit 1 and the second tank unit 1 upwards, when the highest point of a track of the lifted tank unit 1 is higher than the highest points of the vertical wall and the inverted trapezoidal obstacle, all the other tank units 1 on the ground are started to move forward, and the tank track of the first tank unit 1 stops moving forward when being pressed to the highest points of the vertical wall and the inverted trapezoidal obstacle. Then start the whole body shape of the snakelike tank of the downward swing hydraulic cylinder 42 of tank unit 1 of back, the right swing hydraulic cylinder 43 downward swing is slowed down alignment snakelike tank, and then the subaerial tank continues to advance again, after the automobile body of first tank unit 1 was all crossed vertical wall and the trapezoidal obstacle that falls, two the downward swing hydraulic cylinders 42 of second tank unit 1, the downward swing of right swing hydraulic cylinder 43 was the action of bowing, it goes forward to set level first tank unit 1 and go on ground, produce the effect of pulling force to tank unit 1 of back. After the third tank unit 1 crosses the highest point of the vertical wall and the inverted trapezoidal obstacle, according to the lever principle, the total weight of the front three tank units 1 is larger than that of the rear two tanks, so that the rear two tank units 1 are suspended, the last ending action of the snake-shaped tank is completed under the forward pulling force of the front three tank units 1 and under the control of the left swinging hydraulic cylinder 42 and the right swinging hydraulic cylinder 43, and finally all the tanks cross the vertical wall and the inverted trapezoidal obstacle.

3. When the serpentine tank meets the anti-tambour trench with the width lower than 40% of the total length of the serpentine tank as shown in the attached figure 9, the serpentine tank can directly advance through the anti-tambour trench under the condition of depending on the serpentine tank. At this time, the left and right rocking cylinders 42, 43 of each tank unit 1 need only control the body shape of the serpentine tank to maintain a rigid straight state, and then go straight in the direction of the arrow. According to the lever balance principle, the starting point of the anti-tambour trench is taken as a fulcrum, when the two front tank units 1 advance to the upper surface of the anti-tambour trench and are in a suspended state, the total weight of the three rear tank units is larger than that of the two front tank units 1, so the snake-shaped tank can not tip into the anti-tambour trench. After the serpentine tank has proceeded to the tank track of the first tank unit 1 and landed on the opposite side of the anti-tambour trench, the serpentine tank is now a bridge spanning the two ends of the anti-tambour trench and moving like a wheel. When the third tank unit 1 has passed over the anti-tankmaking trench, the total weight of the front three tank units 1 is enough to prevent the two rear suspended tank units 1 from tipping into the anti-tankmaking trench, and the two rear tank units 1 are pulled over the anti-tankmaking trench by the pulling of the front three tank units 1. And at this point, obstacle crossing of the anti-flat-and-bottom trench is completed.

4. When the snake-shaped tank meets the ultra-wide anti-tanken trench shown in the attached drawing 10, namely the width of the anti-tanken trench is more than 40% of the total length of the snake-shaped tank, if the snake-shaped tank linearly advances through the trench, the snake-shaped tank can tip into the trench due to the unbalanced gravity center when the third tank unit 1 passes through the trench according to the lever principle. So snakelike tank is when meetting super wide anti-tambour ditch, if the degree of depth of ditch does not exceed 40% of snakelike tank total length, then can take to lower the head earlier and let first tank unit 1 go down the ground in the ditch, the parallel forward progress of ground of head-raising in the ditch of first tank unit 1 again, four tank unit 1 of back then repeat the action cooperation of first tank unit 1 and follow and go forward. When the first tank unit 1 moves forward to the opposite side of the ultra-wide anti-tankmg trench, the head is raised again to enable the tank track of the first tank unit 1 to be higher than the highest point of the trench, then the tank track moves forward continuously, the first tank unit 1 is completely sent out of the trench by utilizing the matching of the left swing hydraulic cylinder 42 and the right swing hydraulic cylinder 43 of the second tank unit 1, when the first four tank units 1 successively cross the trench, the fifth tank unit 1 moves downwards to suspend in the air to close the tail under the pulling of the previous tank unit 1, at the moment, all tanks already cross the ultra-wide anti-tankmg trench, and obstacle crossing is completed.

5. Front raised anti-tambour when a serpentine tank encounters a front raised anti-tambour as shown in figure 11, there are two situations: 1. if the width of the front raised anti-tankmaking trench is lower than 40% of the total length of the snake-shaped tank, only one more raising action is needed to be carried out at the starting point of the trench, namely, the tank crawler belt of the tank unit 1 is raised higher than the highest point of the opposite surface of the trench, and then the same trench passing method as that shown in the attached figure 9 is adopted for direct passing; 2. if the width of the trench is more than 40% of the total length of the snake-shaped tank, and the heightened height of the opposite side of the trench is less than 40% of the total length of the snake-shaped tank, the same trench crossing method as that shown in the figure 10 needs to be adopted to cross various front heightened counter-tankmarks.

6. Triangular or conical obstacle when snake-shaped tank meets triangular or conical obstacle shown as attached soil 12, firstly, the left-right swing hydraulic cylinder of the second tank unit 1 is started to swing upwards, so that the first tank unit 1 finishes upward head raising action, then four tanks on the ground continue to advance, when the tank track of the first tank unit 1 is pressed on the highest point of the triangular or conical obstacle, the first tank unit 1 is put flat to creep forwards and slowly advance, when the vehicle body of the first tank unit 1 completely passes through the highest point of the triangular or conical obstacle, the front part of the snake-shaped tank can descend due to self weight, the tip of the triangular or conical obstacle can touch the front butt-joint hook beam 2, and if the anti-blocking wheel 22 is blocked, the snake-shaped tank continues to advance. If the front butt hook beam 2 is blocked, the tank behind needs to do head raising action, and the blocked place is raised and suspended to go forward to prevent blocking. When the vehicle body of the first tank unit 1 crosses the peak of a triangular or conical obstacle, a left swing hydraulic cylinder 42 and a right swing hydraulic cylinder 43 of the second tank unit 1 are started to swing downwards to finish the head lowering action, the tank track of the first tank unit 1 is landed, the snake-shaped tank continues to advance again, when the first tank unit 1 advances to travel forwards in parallel with the ground, other tanks at the back finish obstacle crossing by repeating the same action of the first tank unit 1 until the snake-shaped tank finishes the ending action until all the tank units cross the obstacle, and the obstacle crossing is finished at the moment.

7. Circular obstacles and quadrangular obstacles the obstacle detouring method is the same as that shown in fig. 12 when the serpentine tank encounters circular obstacles and quadrangular obstacles shown in fig. 13 to 14.

8. The limit angle of a single tank when the single tank is transversely driven on a slope is about 30 degrees, and the limit angle is determined according to the gravity center position and the width of a vehicle body of the single tank. If it exceeds 30 degrees, the tank will roll over due to imbalance of the center of gravity. As figure 16, when snake-shaped tank is run on the slope and needs to run transversely, because the body shape of snake-shaped tank is very long, every tank unit 1 is equivalent to a universal joint, has the degree of freedom of two directions, and self has the function that imitates biological snake to move about and can advance in S-shaped, because S-shaped is more than the straight line form and can increase the width, so the ability of preventing turning on one' S side is stronger. First, the first clutch sleeve bayonet lock 48, the second clutch sleeve bayonet lock 49 and the third clutch sleeve bayonet lock 57 on three swing hydraulic cylinders on the snake-shaped tank are pulled out, so that the shafts of the three clutch sleeves and the three swing hydraulic cylinders are in a separated state, namely, each tank unit 1 can freely turn like a universal joint. The S-shaped snake-shaped tank moves forward on a slope in an S-shaped manner under the driving of each tank unit 1, so that rollover on the slope can be prevented better, and the snake-shaped tank can transversely pass through the slope more safely.

9. Prevent turning on one's side as shown in figure 15, when snakelike tank had met for example when the action that the soft ground need be done the new head hinders more, owing to raised two preceding tank units 1, leaded to the focus of snakelike tank to show and increased, and ground is soft unstability again, leads to snakelike tank to turn on one's side very easily. At this moment, can only take the action of the curved tail of snakelike tank, be exactly that each subaerial tank unit 1 is the bending form subaerial, like the tail of biological snake is crooked the same, increase the support width of subaerial snakelike tank and just can prevent to turn on one's side better.

10. Sidesway self-rescue can be carried out by adopting the sidesway shown in figure 17 to carry out self-rescue and escape when the snake-shaped tank moves forwards and falls into soft ground to be incapable of moving forwards or backing up to escape accidentally. When a snake-shaped tank falls into soft ground and needs self rescue, at the moment, a left swing hydraulic cylinder 42 of a second tank unit 1 and a third tank unit 1 is started first, a right swing hydraulic cylinder 43 lifts the head of the first tank unit 1 or the second tank unit 1 in front, the tank track is lifted to be higher than the hard ground beside, then a vertical swing hydraulic cylinder 53 is started to enable the lifted tank to rotate to the hard ground, when the lifted tank rotates to the hard ground, the head lowering action is carried out again, the first tank unit 1 or the second tank unit 1 is made to land, if the first tank unit 1 or the second tank unit 1 can directly pull the rear tank out of the soft ground, self rescue and escape are completed. If the first tank unit 1 and the second tank unit 1 which have got on the hard ground can not pull out the following tank on the soft ground, then the snake-shaped tank is required to continue to move laterally by taking the tank on the hard ground as a fulcrum, the third tank unit 1 or the fourth tank unit 1 is continued to move laterally on the hard road surface under the power of each vertical swing hydraulic cylinder, and the fifth tank unit 1 is pulled out. So far, the sidesway of snakelike tank is removed and is saved oneself and get rid of poverty and accomplish.

11. Separation of the tank finally when the target of the snake-shaped tank is too large in military operation and needs to be dispersed to conceal the target, then the snake-shaped tank can be rapidly separated to operate independently for each tank unit. Only after the wedge-shaped clamping pin 31 on the hook opening 3 of the rear butt hook is turned off, the front tank forwards or the rear tank backwards enables the butt hook to be quickly separated, at the moment, each tank can independently act for battle, and the separation working procedure of the snake-shaped tank is finished.

The most main invention point of the snake-shaped tank is a character of 'collective', which can make the fighting capacity of the tank play to the maximum. Utilize and install powerful swing hydraulic pressure mechanism additional and combine each tank unit, make it possess the unique motion characteristics of snake-shaped robot, self possess powerful to single tank incomparable cross-country ability, and when needs dispersion conceal the target, as long as turn off the wedge bayonet lock 31 on the butt hook mouth 3 of back, just can realize the quickly separating between each tank, do not influence the independent operational capability and the performance of every tank again, the changeable flexibility of operational mode.
