DETAILED DESCRIPTION

[0047] Please refer to Figures 1-15 , the present application provides a technical solution:

[0048] As Figure 12 shown is the hydraulic system diagram of the specific implementation of the present application, in this specific implementation: since the present application involves the coordinated action of eight sets of actuators, therefore 8 sets of independent and mutually influencing hydraulic systems are required; in the control of the hydraulic system, the proportional reversing valve 8 and the proportional pressure reducing valve 9 cooperate, the sensor system 2 supervises and Figure 15 The leveling equipment detection control flow shown is used to realize the synchronous jacking of eight cylinders under equal pressure, and complete more accurate control.

[0049] Specifically, the device comprises a sensor system 2, a lifting system 3 and an auxiliary support system 4, wherein the sensor system 2 and the lifting system 3 are both installed on the auxiliary support system 4; the sensor system 2 can monitor and timely feedback the flatness and height of the device during lifting and processing; the lifting system 3 can lift and maintain the workpiece 1; and the auxiliary support system 4 can also complete the centering of the workpiece 1.

[0050] The sensor system 2 comprises two position displacement sensors 2-2, a bracket 2-4, a spoke pressure sensor 2-3 and an inclination sensor 2-1; wherein the bracket 2-4 is installed on the auxiliary support system 4 and used for installing the downward displacement sensor 2-2, which is used for monitoring the distance between the workpiece 1 below and itself and for converting the ground clearance of the workpiece 1;

[0051] The spoke pressure sensor 2-3 is installed on the lifting system 3 and monitors the pressure or tension of each pipe base assembly of the lifting system 3, and can judge the pipe base assembly that cannot be lifted synchronously through the difference between them;

[0052] The inclination sensor 2-1 is installed on the workpiece 1 and is used for monitoring the distance between the workpiece 1 on the side and itself and assisting in the auxiliary judgment of the ground clearance of the workpiece 1 according to its own shape;

[0053] The upward displacement sensor 2-2 is also installed on the auxiliary support system 4.

[0054] As a further scheme of the present application, the lifting system 3 is composed of pipe base assemblies and hydraulic cylinders 3-2; wherein the hydraulic cylinders 3-2 are installed on the auxiliary support system 4, and the spoke pressure sensor 2-3 is arranged on the hydraulic cylinders 3-2, the pipe base assemblies are arranged on the spoke pressure sensor 2-3, all the hydraulic cylinders 3-2 are controlled by a hydraulic system, and the hydraulic system realizes the synchronous jacking of the cylinders under equal pressure through proportional reversing valves 8 and proportional pressure reducing valves 9;

[0055] The hydraulic cylinders 3-2 are power output mechanisms of the system and have the functions of lifting and maintaining; and the pipe base assemblies are used for installing and fixing the workpiece 1;

[0056] As a further scheme of the present application, the pipe base assembly comprises an upper saddle 3-1, a lower saddle 3-3, an upper base 3-3-2 and a lower base 3-3-1; wherein the upper base 3-3-2 is installed on the lower base 3-3-1, the lower saddle 3-3 is fixedly installed on the upper base 3-3-2, the upper saddle 3-1 is arranged below the lower saddle 3-3, and the upper saddle 3-1 and the lower saddle 3-3 are detachably connected through bolts 6.

[0057] If the lifting distance of a group of pipe seat assemblies is insufficient during lifting, the upper saddle 3-1 is pressed by the workpiece 1 at this time, and the spoke pressure sensor 2-3 is in tension at this time, so it can be judged that the lifting distance of the corresponding pipe seat assembly is insufficient; similarly, if the lifting distance of a group of pipe seat assemblies is excessive during lifting, the lower saddle 3-3 is pressed by the workpiece 1 at this time, and the spoke pressure sensor 2-3 is in compression at this time, so it can be judged that the lifting distance of the corresponding pipe seat assembly is excessive.

[0058] As a further scheme of the application: the upper base 3-3-2 is provided with a through circular arc groove 3-3-3, and the upper base 3-3-2 and the lower base 3-3-1 are detachably connected through the connecting plate 3-4 penetrating the circular arc groove 3-3-3, and the circular arc groove 3-3-3 of the connecting plate 3-4 is used to change the relative position of the upper base 3-3-2 and the lower base 3-3-1.

[0059] By changing the relative position of the upper base 3-3-2 and the lower base 3-3-1, the flatness of the workpiece 1 after installation can be further improved, and the workpiece 1 is first installed on the lower saddle 3-3, and then the upper saddle 3-1 is fixed on the lower saddle 3-3 by bolts 6 for stabilizing the workpiece 1.

[0060] As a further scheme of the application: the auxiliary support system 4 includes a plurality of support seat assemblies 4-2, a plurality of support seat connecting pieces 4-3 and a centering device 4-1; wherein every two support seat assemblies 4-2 are connected by a support seat connecting piece 4-3, and the support seat connecting piece 4-3 is provided with a centering device 4-1. The support seat assembly 4-2 is mainly used for installing the sensor system 2 and the lifting system 3. The centering device 4-1 on it is used to adjust the centering performance during lifting after the workpiece 1 is installed.

[0061] As a further scheme of the application: the centering device 4-1 includes a mounting seat 4-1-2, and a push plate 4-1-1 is threadedly connected to the mounting seat 4-1-2.

[0062] As a further scheme of the application: the auxiliary support system 4 further includes an adjusting base plate 4-4 and a platform fixing assembly 4-5.

[0063] The adjusting base plate 4-4 is used to improve the flatness when the whole application is installed on the ground or base, and the platform fixing assembly 4-5 is used to connect the whole application and the ground or base.

[0064] The centering device 4-1 is installed on the auxiliary support system 4, and there are four sets in four directions. It is used for auxiliary centering, mainly composed of a push plate 4-1-1 and a mounting seat 4-1-2. When the workpiece 1 is installed, the front and rear positions of the push plate 4-1-1 can be changed by adjusting the nut on the mounting seat 4-1-2, so that the push plate 4-1-1 can be close to the workpiece 1 to improve the centering characteristics of the workpiece 1 during lifting and processing.

[0065] Because the hydraulic cylinder is adjusted in advance, the workpiece 1 is often lifted by the crane first, and then placed on the upper end of the hydraulic cylinder to realize leveling. However, during the lifting process of the crane, the workpiece 1 is easy to shake, and the huge inertia is easy to cause the hydraulic cylinder to break and bend. Therefore, it is hoped that there is a buffer device when the workpiece 1 contacts the system body to make the workpiece 1 and the hydraulic cylinder flexible contact. However, the general buffer device will affect the accuracy. In order to solve the technical problem:

[0066] The pipe seat assembly is also provided with a buffer assembly 5, which comprises a mounting rack 5-1 symmetrically fixed on the support seat assembly 4-2 by bolts 6. Four first guide rods 5-2 are fixedly arranged on the mounting rack 5-1. A first reset spring 5-3 is arranged on each first guide rod 5-2. The upper ends of the reset springs on the same side are connected to a connecting frame 5-5 through a connecting sleeve sleeved with the first guide rod 5-2. The connecting frames 5-5 on both sides can be spliced into a complete support frame. The connecting frames 5-5 are elastically connected to clamping frames 5-8 through first and second adjusting springs. When the connecting frames 5-5 on both sides are spliced, the two clamping frames 5-8 can also be spliced to form a closed clamping frame for clamping the upper base 3-3-2. Limiting sliding grooves are formed on both sides of the clamping frame. The upper base 3-3-2 is provided with limiting sliding edges matched with the limiting sliding grooves.

[0067] In work, referring to Figures 6-10 (the spoke type pressure sensor 2-3 has been hidden), now the mounting racks 5-1 on both sides are fixed on the support seat assembly 4-2 through bolts 6. During this process, attention should be paid to the splicing of the connecting frames 5-5 on both sides (such as Figure 9The specific embodiment given in the specification: let one side of the plug-in block 5-5-1 plug into the corresponding slot of the other connecting frame 5-5, and the limiting groove on the two clamping frames 5-8 cooperates with the limiting slide rib of the upper base 3-3-2; when the installation of the installation frame 5-1 is completed, the crane lifts the workpiece 1, and the shaking of the workpiece 1 will first contact the lower saddle 3-3, and will drive the lower saddle 3-3 to elastically vibrate or shake in the support frame. Since the workpiece 1 is in a suspended state, the force point is the crane, so the first buffer spring 5-6 and the second buffer spring 5-7 in the support frame can quickly absorb the inertia of the workpiece 1 in the horizontal direction and guide the workpiece 1, and then the crane slowly descends, and finally the upper base 3-3-2 and the lower base 3-3-1 are in contact. At this time, the worker can use the connecting plate 3-4 to connect the upper base 3-3-2 and the lower base 3-3-1; when the connection is firm, the bolts 6 of the two installation frames 5-1 are loosened, and the installation frame 5-1 is pulled out from both sides, so that the disengagement between the clamping frame 5-8 and the upper base 3-3-2 is completed.

[0068] The present application utilizes the detachable buffer assembly 5, which can make the workpiece 1 and the whole system not be broken or bent due to the swinging of the hoisting in the contact instant, thereby providing a strong basis for subsequent leveling. At the same time, the buffer assembly 5 is simple in structure and convenient to disassemble, which effectively reduces the use, maintenance and manufacturing costs.

[0069] When the swing amplitude of the workpiece 1 is large due to harsh environmental factors of welding, if the relative position of the two clamping frames 5-8 cannot be controlled, the lower saddle 3-3 may slide back and forth between the two clamping frames 5-8, which is not conducive to improving the guiding efficiency.

[0070] As a further scheme of the present application: the clamping frame is further provided with a locking unit, the locking unit comprises a pressing block 5-8-1 fixedly arranged on the upper end of the clamping frame 5-8, and the other clamping frame 5-8 is elastically rotatably provided with a pressing piece 5-8-2 through a support two 5-8-3 and a second reset spring 5-8-4, a push rod 5-8-5 is penetratingly arranged on the corresponding clamping frame 5-8 at the lower end of the pressing piece 5-8-2, and a driving block 5-4 is fixedly arranged on the side wall of the lower base 3-3-1 corresponding to the lower end of the push rod 5-8-5. When the push rod 5-8-5 approaches the driving block 5-4, it can be lifted by the driving block 5-4 and press down the pressing piece 5-8-2, so that the pressing piece 5-8-2 and the pressing block 5-8-1 are disengaged.

[0071] In use: as Figure 8 In combination Figure 10When the two clamping frames 5-8 are close to each other and contact each other, the pressing plate 5-8-2 can be pressed into the lower side of the pressing block 5-8-1 and buckled and locked with the pressing block 5-8-1. At this time, the positions of the two clamping frames 5-8 are locked and form a block-shaped whole with the upper base 3-3-2, and then, as the workpiece 1 is lowered, when the push rod 5-8-5 falls and contacts the driving block 5-4, the driving block 5-4 drives the push rod 5-8-5 to move upwards and lifts the pressing plate 5-8-2, so that the other end of the pressing plate 5-8-2 is separated from the buckling. At this time, the unlocking is completed, and the mounting frame 5-1 can be pulled out to the two sides.

[0072] In this part, the opening and closing device with automatic locking and automatic unlocking enables the two clamping frames 5-8 to remain relatively fixed during the longitudinal movement of the upper base 3-3-2 and to be automatically unlocked when it is necessary to be separated, which is beneficial to the stable operation of the buffer assembly 5 and can also increase the application range of the leveling system.

[0073] Since the accuracy requirement for the longitudinal direction is very high, and the radial force acting on the cylinder rod can easily cause the hydraulic oil cylinder 3-2 to be damaged, it is desirable that when the length of the hydraulic oil cylinder 3-2 is relatively long, a balancing unit can balance the radial force acting on it, especially when the positions of the upper base 3-3-2 and the lower base 3-3-1 are not completely vertical.

[0074] As a further scheme of the present application, the support seat assembly 4-2 further comprises a balancing unit, the balancing unit comprises a base 7 which can be fixed on the support seat assembly 4-2 by bolts 6, two sliding mounting tables 7-3 are slidingly arranged on the base 7, a first adjusting stud 7-1 is threadedly arranged on the lower sliding mounting table 7-3, second guide rods 7-5 are arranged on the two sides of the first adjusting stud 7-1 and are sleeved with the sliding mounting table 7-3, a balancing seat 7-4 is fixed at the ends of the two second guide rods 7-5, the position of the balancing seat 7-4 can be adjusted to support the cylinder rod radially when the first adjusting stud 7-1 is rotated, a second adjusting stud 7-2 is threadedly connected to the upper sliding mounting table 7-3, the second adjusting stud 7-2 is connected to the upper base 3-3-2 through a ball head connecting piece 7-6, and the relative position of the upper base 3-3-2 and the lower base 3-3-1 can be adjusted when the second adjusting stud 7-2 is rotated.

[0075] In this part, the base 7 is fixed on the support seat assembly 4-2, and the position of the balancing seat 7-4 is adjusted by the first adjusting stud 7-1, so that the balancing seat 7-4 abuts against the cylinder rod (in actual use, the support seat assembly 4-2 needs to be close to the workpiece 1, so the pipe used for support in the design stage will not cause the cylinder rod to be subjected to a component force in the direction of the workpiece 1). Secondly, when it is necessary to adjust the relative position of the lower base 3-3-1 and the upper base 3-3-2, only the second adjusting stud 7-2 needs to be adjusted.

[0076] As a further scheme of the present application, the control method of the high-load multi-cylinder hydraulic jacking leveling system comprises the following steps:

[0077] Step 001 is performed: the system is powered on;

[0078] Step 002 is performed: fault judgment is performed, if yes, the system alarms and waits for fault handling; if no, the installation mode button is pressed;

[0079] Step 003 is performed: the displacement sensor 2-2, the spoke pressure sensor 2-3 and the inclination sensor 2-1 continuously collect data and transmit the data to the processor;

[0080] Step 004 is performed: whether it is horizontal is judged, if yes, the equipment balance indicator light is turned on, and Step 005 is performed; if no, Step 0041 is performed;

[0081] Step 0041 is performed: the leveling system starts automatic leveling, and returns to Step 004;

[0082] Step 005 is performed: after the equipment is installed, the welding mode button is pressed, and the welding mode light is turned on;

[0083] Step 006 is performed: welding is started;

[0084] Step 007 is performed: whether it is horizontal and whether the gravity is balanced are judged in real time, if yes, the HML displays the inclination, the welding is continued, and Step 008 is performed; otherwise, Step 0071 is performed;

[0085] Step 0071 is performed: the leveling system starts automatic leveling;

[0086] Step 0072 is performed: whether it is horizontal is judged, if yes, it returns to Step 006; if no, it returns to Step 0071;

[0087] Step 008 is performed: the welding is completed and the equipment is unloaded;

[0088] Step 009 is performed: the leveling system returns to the original point, and the leveling equipment detection is ended.

[0089] As Figure 15The leveling equipment detection control flow chart of the application is shown. When the system is powered on to start detection, first fault judgment is carried out. If there is a fault, an alarm is given to wait for further processing. When the detection is completed, the installation mode button is pressed. At this time, the system starts automatic leveling according to the readings of each sensor to complete leveling. At this time, the indicator light will be on. When the equipment is completed, the welding mode button is pressed. At this time, the welding mode light is on, and the state of operating the workpiece 1 is entered. In the operation process, the system judges whether the gravity is balanced and whether it is horizontal in real time. If any item does not meet the requirements, the welding mode is stopped. The system needs to complete the horizontal adjustment again, and the above steps are repeated. In the above steps, the inclination of the system is displayed in real time by the HMI. After the operation is completed, the equipment can be disassembled and the system can be returned to the home position, and the leveling equipment detection is ended.
