Description
Technical Field
The invention relates to a translation method for a large building.
Background
The existing equipment synchronous jacking equipment adopts a method for controlling the valve opening and closing time in the same time, and the method controls the valve opening time in every 1 second according to a signal fed back by a displacement sensor when the equipment runs. If the value of the displacement sensor is larger than the average value of the displacement signals returned by each oil cylinder, the valve opening time is correspondingly increased according to the value; if the value of the displacement sensor is smaller than the average value of the displacement signals returned by the oil cylinders, the valve opening time is correspondingly reduced according to the value; and if the displacement sensor value and the average value of the displacement signals returned by the oil cylinder are the same, the valve opening time is operated according to a set value. The method has the disadvantage that the valve is opened and closed every 1 second, so that the long-time frequent opening and closing of the electromagnetic valve can cause a certain degree of damage to the electromagnetic valve, and the service life of the electromagnetic valve is seriously influenced. If a better proportioner valve is used, the cost of the equipment is greatly increased.
Disclosure of Invention
The invention aims to solve the technical problem that the service life of an electromagnetic valve is seriously influenced because the electromagnetic valve is damaged to a certain extent when the lifting equipment is frequently opened and closed for a long time in the operation process in the prior art. Provides a translation method for large buildings.
The invention solves the technical problems through the following technical scheme:
the large building translation method is characterized by comprising a jacking process, wherein the jacking process sequentially comprises the following steps:
a1, setting a step pitch X of each jacking and a total displacement Y of target jacking;
step A2, moving a jacking point by a step X;
step A3, judging whether the displacement of the jacking point reaches the total displacement Y, pausing jacking if the jacking point is larger than or equal to the total displacement Y, and continuing to execute the step A2 if the jacking point is smaller than the total displacement Y;
step A4, after all the jacking points reach the total displacement Y, judging whether the total displacement Y reaches the preset lifting height,
if the lifting height is larger than or equal to the preset lifting height, stopping lifting at all the lifting points;
if the total displacement is smaller than the preset lifting height, the step pitch X is increased on the original total displacement Y to form a new total displacement Y, and all the jacking points return to execute the step A2.
Aiming at the damage of the electromagnetic valve caused by frequent switching of the electromagnetic valve, a method of following a set value is adopted. That is, a step X is first set, and after the start of the operation, the step X is used as a follow-up value, and the operation of each point follows the follow-up value. If the displacement value returned by each point is larger than or equal to the value, adding a step distance as a new following value; if the return value of at least one point does not reach the following value, other points do not act first, wait for the displacement value returned by the last point to reach the following value, and act again together after the following value is increased. The benefits thereby accrue are: the electromagnetic valve does not act every second any more, but acts once every step X, so that the action times of the electromagnetic valve are greatly reduced, and the damage to the electromagnetic valve is reduced. And the step pitch is used for controlling the action of the electromagnetic valve, so that the synchronous precision is ensured. If the precision requirement is higher, the length of the step X can be properly reduced; if the precision requirement is low, the length of the step pitch X can be properly increased, and the flexibility can be mastered by an operator.
Preferably, after each jacking point finishes executing step A2, the method is divided into three states, including:
in the state 1, all jacking points reach the total displacement Y;
in the state 2, part of the jacking points reach the total displacement Y, and part of the jacking points do not reach the total displacement Y;
in the state 3, all jacking points do not reach the total displacement Y;
each jacking point is initially in state 3, runs to state 2, and finally to state 1.
Preferably, the jacking equipment controls the movement of the oil cylinder through the opening and closing of an electromagnetic valve, wherein in the step A2, the electromagnetic valve is opened so that the oil cylinder moves by the step X; in the step A3, the electromagnetic valve is closed so that the oil cylinder stops jacking.
Preferably, step A1 further includes:
step A1.1, enabling each jacking point to be located at a zero position;
step A1.2, setting a step X of each jacking and a total displacement Y of target jacking;
and A1.3, detecting, and if no alarm exists, entering the step A2.
Preferably, include the power flow of suspending after the jacking flow is accomplished, the power flow of suspending includes in proper order:
b1, detecting the pressure of the oil cylinder, a high-pressure set value of a force closed loop and a low-pressure set value of the force closed loop, and entering a step B2.1 if the pressure of the oil cylinder is smaller than the low-pressure set value of the force closed loop; if the pressure of the oil cylinder is larger than the force closed loop high-pressure set value, entering the step B2.2; if the pressure of the oil cylinder is between the high-pressure set value of the force closed loop and the low-pressure set value of the force closed loop, entering the step B2.3;
step B2.1, opening the electromagnetic valve to supplement pressure to the oil cylinder, and returning to the step B1;
step B2.2, opening the electromagnetic valve to reduce the pressure of the oil cylinder, and returning to the step B1;
and step B2.3, the electromagnetic valve does not act.
After the equipment is jacked in place or is replaced in place, the hydraulic system leaks to a certain extent, so that the oil cylinder sinks or the supporting force is insufficient at some points. Therefore, in the single jacking equipment, some point pressure is too small, the support is less, and some point pressure is too large, so that the oil cylinder or the load is damaged to a certain extent. In jacking and pushing equipment, the friction force is too small due to too small jacking force of some points, and the function is very small in the jacking and pushing process; the friction force of the nearby oil cylinder is too large, and the oil cylinder is possibly damaged to a certain extent.
Aiming at the pressure drop of the oil cylinder caused by the leakage of the oil cylinder or the oil circuit, a force suspension method is adopted. In the force suspension state, if the force of a certain point is smaller than the force set value by a certain proportion, the point is repressed until the set value is reached.
Preferably, the force levitation procedure is performed without an alarm.
Preferably, include position suspension flow after the jacking flow is accomplished, position suspension flow includes in proper order:
c1, detecting the position of the oil cylinder, a high-order set value of a position closed loop and a low-order set value of the position closed loop, and entering the step C2.1 if the position of the oil cylinder is less than the low-order set value of the position closed loop; if the position of the oil cylinder is larger than the position closed loop high-position set value, entering a step C2.2; if the position of the oil cylinder is between the position closed loop high-order set value and the position closed loop low-order set value, entering the step C2.3;
c2.1, opening the electromagnetic valve to enable the oil cylinder to work to perform position supplement, and returning to the step C1;
step C2.2, opening the electromagnetic valve to enable the oil cylinder to work and reduce the position, and returning to the step C1;
and C2.3, the electromagnetic valve does not act.
And aiming at position falling caused by oil cylinder or oil circuit leakage, a position suspension method is adopted. In the position suspension state, if the position of a certain point is smaller than the position set value by a certain proportion, the point is repressed until the set value is reached.
Preferably, the position levitation process is performed without an alarm.
Preferably, when the position of the jacking point is synchronized, the large building translation method includes a force following process, and the force following process sequentially includes:
d1, detecting the pressure of the oil cylinder, a force following high-pressure set value and a force following low-pressure set value, and entering a step D2.1 if the pressure of the oil cylinder is smaller than the force following low-pressure set value; if the pressure of the oil cylinder is larger than the force following high-pressure set value, the step D2.2 is carried out; if the pressure of the oil cylinder is between the force following high-pressure set value and the force following low-pressure set value, the step D2.3 is carried out;
step D2.1, increasing the rotating speed of a motor of the pump, and returning to the step D1;
step D2.2, reducing the rotating speed of a motor of the pump, and returning to the step D1;
and D2.3, keeping the rotating speed of the motor of the pump.
In the pushing process, the existing method adopts a position synchronization method, namely all the oil cylinders control the walking of the oil cylinders according to position signals fed back by the displacement sensors. The method has the defects that the force of moving the oil cylinder according to the displacement is too small, the effect in the pushing process is very small, and the force of other oil cylinders is too large, so that the oil cylinder or the load can be damaged to a certain extent. Some oil cylinders have too large force and can damage the oil cylinders or the load.
Aiming at the problem that the force of the oil cylinder is too large or too small during position synchronization, a force following mode is adopted. Namely, the existing translation point does not adopt a position synchronization mode, but sets a required pressure value. If the pressure is always relatively low or relatively high at the translation points during position synchronization, the points adopt a force following mode. When the ratio of the pressure at the point to the set value is smaller than a certain value, the pump accelerates; when the pressure at this point is greater than a certain value compared to the set point, the pump is slowed down.
Preferably, when synchronizing the force of the jacking point, the method for translating the large building includes a position following process, and the position following process sequentially includes:
e1, detecting the position of the oil cylinder and the position set value, and entering a step E2.1 if the position of the oil cylinder is less than the position set value; if the position of the oil cylinder is larger than the position set value, entering a step E2.2; if the position of the oil cylinder is equal to the position set value, entering a step E2.3;
step E2.1, increasing the rotating speed of a motor of the pump, and returning to the step E1;
step E2.2, reducing the rotating speed of the motor of the pump, and returning to the step E1;
and E2.3, keeping the rotating speed of the motor of the pump.
The system does not adopt a force following point, and adopts a position following mode. That is, the existing translation points do not adopt a force synchronization mode, but set a required position value. When the position of the point is less than the set value, the pump is accelerated; when this point is located above the set point, the pump decreases speed.
The positive progress effects of the invention are as follows: the invention greatly reduces the action times of the electromagnetic valve, thereby reducing the damage of the electromagnetic valve, and adopts the step pitch to jack, thereby ensuring the precision.

Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
As shown in fig. 1-5, the present embodiment discloses a large building translation method, which performs jacking by using jacking equipment, wherein, as shown in fig. 1, the large building translation method includes a jacking process, and the jacking process sequentially includes:
a1, setting a step pitch X of each jacking and a total displacement Y of target jacking;
step A2, moving a jacking point by a step X;
step A3, judging whether the displacement of the jacking point reaches the total displacement Y, pausing jacking if the jacking point is larger than or equal to the total displacement Y, and continuing to execute the step A2 if the jacking point is smaller than the total displacement Y;
step A4, after all the jacking points reach the total displacement Y, judging whether the total displacement Y reaches the preset lifting height,
if the lifting height is larger than or equal to the preset lifting height, stopping lifting at all the lifting points;
if the total displacement is smaller than the preset lifting height, the step X is added to the original total displacement Y to form a new total displacement Y, and all the jacking points return to execute the step A2.
Aiming at the damage of the electromagnetic valve caused by frequent switching of the electromagnetic valve, a method of following a set value is adopted. That is, a step X is first set, and after the start of the operation, the step X is used as a follow-up value, and the operation of each point follows the follow-up value. If the displacement value returned by each point is larger than or equal to the value, adding a step distance as a new following value; if the return value of at least one point does not reach the following value, other points do not act first, the displacement value returned by the last point also reaches the following value, and the following value is increased and then acts again together. The advantages that result from this are: the electromagnetic valve does not act every second any more, but acts once every step X, so that the action times of the electromagnetic valve are greatly reduced, and the damage to the electromagnetic valve is reduced. And the step pitch is used for controlling the action of the electromagnetic valve, so that the synchronous precision is ensured. If the precision requirement is higher, the length of the step X can be properly reduced; if the precision requirement is low, the length of the step pitch X can be properly increased, and the flexibility can be mastered by an operator.
In this embodiment, after each jacking point executes step A2, the jacking point is divided into three states, including:
in the state 1, all jacking points reach the total displacement Y;
in the state 2, part of the jacking points reach the total displacement Y, and part of the jacking points do not reach the total displacement Y;
in a state 3, all jacking points do not reach the total displacement Y;
each jacking point is initially in state 3, runs to state 2, and finally to state 1.
In this embodiment, the jacking device controls the movement of the oil cylinder by opening and closing the electromagnetic valve, wherein in step A2, the electromagnetic valve is opened to move the oil cylinder by a step X; in the step A3, the electromagnetic valve is closed, so that the oil cylinder stops jacking.
In this embodiment, step A1 further includes:
step A1.1, enabling each jacking point to be located at a zero position;
step A1.2, setting a step X of jacking each time and a total displacement Y of target jacking;
and A1.3, detecting, and if no alarm exists, entering the step A2.
As shown in fig. 2, in this embodiment, the jacking process includes a force suspension process after the jacking process is completed, and the force suspension process sequentially includes:
b1, detecting the pressure of the oil cylinder, a force closed loop high-pressure set value and a force closed loop low-pressure set value, and entering the step B2.1 if the pressure of the oil cylinder is smaller than the force closed loop low-pressure set value; if the pressure of the oil cylinder is larger than the force closed loop high-pressure set value, entering the step B2.2; if the pressure of the oil cylinder is between the high-pressure set value of the force closed loop and the low-pressure set value of the force closed loop, entering the step B2.3;
step B2.1, opening the electromagnetic valve to supplement pressure to the oil cylinder, and entering step B3;
step B2.2, opening the electromagnetic valve to reduce the pressure of the oil cylinder, and returning to the step B1;
step B2.3, the electromagnetic valve does not act;
and step B3, detecting whether the position is greater than a pressure maintaining set value, wherein the pressure maintaining set value is a value between a pressure closed loop high-pressure set value and a pressure closed loop low-pressure set value, if so, returning to the step B1, otherwise, returning to the step B2.1.
After the equipment is jacked in place or is shifted in place, the oil cylinder sinks or the supporting force is insufficient at some points due to certain leakage of a hydraulic system. Therefore, in the single jacking equipment, the problems that the support is little due to too small point pressure and the damage to the oil cylinder or the load to a certain degree is caused due to too large point pressure can be caused. In jacking and pushing equipment, the friction force is too small due to too small jacking force of some points, and the function is very small in the jacking and pushing process; the friction force of the nearby oil cylinder is too large, and the oil cylinder is possibly damaged to a certain extent.
Aiming at the pressure drop of the oil cylinder caused by the leakage of the oil cylinder or the oil circuit, a force suspension method is adopted. In the force suspension state, if the force of a certain point is smaller than the force set value by a certain proportion, the point is repressed until the set value is reached.
In this embodiment, the force levitation process is performed without an alarm.
As shown in fig. 3, in this embodiment, the jacking process includes a position suspension process after the jacking process is completed, where the position suspension process sequentially includes:
c1, detecting the position of the oil cylinder, a high-order set value of a position closed loop and a low-order set value of the position closed loop, and entering the step C2.1 if the position of the oil cylinder is less than the low-order set value of the position closed loop; if the position of the oil cylinder is larger than the position closed loop high-position set value, entering a step C2.2; if the position of the oil cylinder is between the position closed loop high-position set value and the position closed loop low-position set value, entering the step C2.3;
c2.1, opening the electromagnetic valve to enable the oil cylinder to work for position supplement, and entering the step C3;
step C2.2, opening the electromagnetic valve to enable the oil cylinder to work and reduce the position, and returning to the step C1;
step C2.3, the electromagnetic valve does not act;
and C3, detecting whether the position is larger than a position closed loop set value, wherein the position closed loop set value is a value between a position closed loop high-order set value and a position closed loop low-order set value, if so, returning to the step C1, and otherwise, returning to the step C2.1.
And aiming at position falling caused by oil cylinder or oil circuit leakage, a position suspension method is adopted. In the position suspension state, if the position of a certain point is smaller than the position set value by a certain proportion, the point is repressed until the set value is reached.
In this embodiment, the position levitation process is performed without an alarm.
As shown in fig. 4, in this embodiment, when the position of the jacking point is synchronized, the large building translation method includes a force following process, and the force following process sequentially includes:
d1, detecting the pressure of the oil cylinder, a force following high-pressure set value and a force following low-pressure set value, and entering a step D2.1 if the pressure of the oil cylinder is smaller than the force following low-pressure set value; if the pressure of the oil cylinder is larger than the force following high-pressure set value, the step D2.2 is carried out; if the pressure of the oil cylinder is between the force following high-pressure set value and the force following low-pressure set value, the step D2.3 is carried out;
step D2.1, increasing the rotating speed of a motor of the pump, and returning to the step D1;
step D2.2, reducing the rotating speed of a motor of the pump, and entering step D3;
d2.3, keeping the rotating speed of a motor of the pump;
and D3, judging whether the pressure of the oil cylinder is smaller than a force following set value, wherein the force following set value is a value between a force following high-pressure set value and a force following low-pressure set value, if so, returning to the step D1, and otherwise, returning to the step D2.2.
In the pushing process, the existing method adopts a position synchronization method, namely all the oil cylinders control the walking of the oil cylinders according to position signals fed back by the displacement sensors. The method has the defects that the force of moving the oil cylinder according to the displacement is too small, the effect in the pushing process is very small, and the force of other oil cylinders is too large, so that the oil cylinder or the load can be damaged to a certain extent. Some oil cylinders have too large force and can damage the oil cylinders or the load.
Aiming at the problem that the force of the oil cylinder is too large or too small during position synchronization, a force following mode is adopted. Namely, the existing translation points do not adopt a position synchronization mode, but set a required pressure value. If the pressure is always relatively low or relatively high at the translation points during position synchronization, the points adopt a force following mode. When the ratio of the pressure at the point to the set value is smaller than a certain value, the pump accelerates; when the pressure at this point is greater than a set value, the pump is slowed down.

step E2.2, reducing the rotating speed of the motor of the pump, and returning to the step E1;
and E2.3, keeping the rotating speed of the motor of the pump.
The system does not adopt a force following point, and adopts a position following mode. That is, the existing translation point does not adopt a force synchronization mode, but sets a required position value. When the position of the point is less than the set value, the pump accelerates; when this point is located above the set point, the pump decreases speed.
