The chain wheel-chain transmission mechanism of each step can adopt a transmission mode such as synchronous belt transmission or gear transmission in other embodiments. The reason why the synchronous lifting can be realized by adopting the tooth numbers is as follows:

definition of synchronous ascending and descending of each step 411: in the same time, each step 411 needs to complete lifting at the same time to reach a specified height, so that the height difference of the adjacent steps 411 is equal and equal to the preset height difference;

assuming that initially, the height difference between the adjacent steps 411 is H1, the steps 411 are lifted and lowered synchronously: in the same time, the height difference of each step 411 is consistent, so that the lifting strokes of each step 411 are different,

then, the height of the first step from the ground is H1, the height of the second step from the ground is 2H1, the height of the third step from the ground is 3H1, the height of the fourth step from the ground is 4H1, the height of the fifth step from the ground is 5H1 … …, and so on, and the height of the nth step from the ground is nH 1;

if the predetermined height difference required to be achieved by the adjacent steps 411 is H2, wherein the units of H2 and H1 are the same, for example, the units are mm.

The ground height of the first step is H2, the ground height of the second step is 2H2, the ground height of the third step is 3H2, the ground height of the fourth step is 4H2, and the ground height of the fifth step is 5H 2;

then it can be derived: the height difference is lifted from H1 to H2, the height of the first step needing to be lifted is H2-H1, the height of the second step needing to be lifted is 2H2-2H1, the height of the third step needing to be lifted is 3H2-3H1, the height of the fourth step needing to be lifted is 4H2-4H1, the height of the fifth step needing to be lifted is 5H2-5H1 … … and the like, and the height of the nth step needing to be lifted is nH2-nH 1; each step can only be synchronously lifted or synchronously lowered, so that the lifting height required by each step is positive, and the step is lifted; if negative, then descending; therefore, the height ratio of the required lifting of each step is: 1:2:3:4:5 … …: n is an equal ratio sequence;

for example: taking 5 steps as an example, assuming that the height difference of each step is 120mm,

the first step is 120mm away from the ground, the second step is 240mm away from the ground, the third step is 360mm away from the ground,

the fourth step is 480mm away from the ground, and the fifth step is 600mm away from the ground.

If the height difference is raised to 200 f,

the first step is 200mm away from the ground, the second step is 400mm away from the ground, the third step is 600mm away from the ground,

the fourth step is 800mm away from the ground, and the fifth step is 1000mm away from the ground.

Then it can be derived: the height difference is increased from 120mm to 200mm, the first step needs to be lifted by 80mm, the second step is lifted by 160mm, the third step is lifted by 240mm, the fourth step is lifted by 320mm, and the fifth step is lifted by 400 mm.

Because synchronous lifting is carried out, the time t is the same, and according to a distance formula s-vt, t and the height difference are substituted into the formula, so that the following can be obtained:

the first step speed is assumed to be x, the second step speed is 2x, the third step speed is 3x, the fourth step speed is 4x, the fifth step speed is 5x … … and the like, and the nth step speed is nx; in a specific embodiment, the speed unit of each step is mm/s; the unit of the output rotating speed of the fifth speed reducer is r/s, and the unit of the lead of the second spiral elevator 4127 is mm; in other embodiments, other units can be used, and the unit change only needs unit conversion.

Assuming that the output rotation speed of the fifth speed reducer is A, for example, the unit is r/s;

the second spiral elevator 4127 of each step has a speed ratio of B;

the second helical lift 4127 has a lead of C, for example in mm;

input-output ratio of sprocket-chain transmission: first order D1; second order D2; the third order is D3, and the fourth order is D4; the fifth order is D5; … … and so on, the nth order is Dn;

then it can be derived:

the speed x of the first step is (a/B/D1) C;

the speed of the second step 2 ═ (a/B/D2) × C;

the speed of the third step, 3x ═ (a/B/D3) × C;

the speed of the fourth step, 3x ═ C (a/B/D4);

the speed of the fifth step 4x ═ C (a/B/D5) × C

… …, and so on, the speed of the nth step is nx ═ a/B/Dn × (C).

Assuming that, in order from low to high, the fifth reducer 4122 is connected to the second spiral lifter of the third step; then, the third step is a direct connection, and D3 is 1;

by 3 sets of simultaneous equations: fig. 3x (a/B/D3) × C, … …

x＝(A/B/D1)*C，……⑵

D3＝1，……⑶

D1-3 x D3-3 can be derived;

by analogy, D2 is 1.5 × D3 is 1.5;

D4＝0.75*D3＝0.75；

D5＝0.6*D3＝0.6；

……

Dn＝3/n；

that is, the input-output ratio of each chain wheel-chain transmission must meet the above ratio, so as to ensure that each step is lifted synchronously to reach the preset height difference;

by analogy, when the fifth speed reducer 4122 is directly connected with a certain step 411, the input and output of the sprocket-chain transmission of the step 411 is 1, and then the input and output are substituted into the equation set for calculation.

From this it can be calculated:

firstly, under the condition that the speed ratio of the second spiral elevator 4127 of each step 411 is consistent:

for example, suppose a third step sprocket with 10 teeth and a second step sprocket with 15 teeth, a first step sprocket with 15 teeth and a second step sprocket with 30 teeth;

assuming that the third and fourth sprockets are used for transmission, wherein the number of the third sprocket teeth is 20, the fourth sprocket teeth is 15; the chain wheel is used for fourth-order and fifth-order transmission, wherein the number of teeth of the fourth order is 15 teeth, and the number of teeth of the fifth order is 12 teeth;

other combinations of tooth numbers are possible as long as the step speed ratios are satisfied. Not only the current number of teeth. In specific implementation, the specification of the chain wheel can be selected according to the ratio of the input-output speed ratio according to requirements.

Secondly, in the case that the speed ratio of the second screw lifters 4127 is not uniform for each step 411,

for example, assume a first step helical step up-down speed ratio of 12;

the second step spiral lifting speed ratio is 6;

the spiral ascending and descending speed ratio of the third step is 6;

the fourth step spiral lifting speed ratio is 6;

the speed ratio of the fifth step of spiral lifting is 6;

assuming a third step and a second step drive sprocket, wherein the third step sprocket uses 10 teeth, the second step uses 15 teeth; second step and first step drive sprocket, second step use 15 teeth, first step use 15 teeth;

assuming that the third and fourth sprockets are used for transmission, wherein the number of the third sprocket teeth is 20, the fourth sprocket teeth is 15; the chain wheel is used for fourth-order and fifth-order transmission, wherein the number of teeth of the fourth order is 15 teeth, and the number of teeth of the fifth order is 12 teeth;

this can result in: the speed ratio of the second spiral elevator changes, the input-output ratio of the chain wheel-chain transmission also changes, and then the spiral elevator speed ratio and the chain transmission input-output ratio are relatively combined. Synchronous rising and falling of the steps is achieved.

In a specific embodiment, the method further comprises

A fifth encoder 43; the fifth encoder 43 is also communicatively connected to the controller 5;

an encoder support 44, on which the fifth encoder 43 is fixed; in one embodiment, the encoder support 44 may be fixed directly to the ground, or may be fixed to other supporting objects, depending on the location.
