Description

Technical Field

[0001] The invention relates to the field of gear box support, and more particularly to an elastic rubber pad powered by an accumulator and a method for using the same. Background Art

[0002] With the investment in R&D and the continuous scientific research in the wind power industry, it can be seen that wind turbines have developed towards the direction of increasing rated power, increasing torsional load, increasing power generation efficiency and decreasing power generation cost, from the initial 750KW units, the general 1.5MW 3MW units in the past few years, to the currently popular 5MW 7MW units and the newly developed and tested 8MW 14MW units.

[0003] In order to ensure the smooth output of the torque of the gearbox components in the transmission system of the wind turbine generator set and to minimize the vibration and noise generated by the operation of the system, the role of the gearbox elastic support that fixes the torque arms at both ends of the gearbox is particularly important.

[0004] At present, the gearbox elastic support mainly includes stacked spring type and hydraulic type. Among them, the existing hydraulic auxiliary gearbox elastic support is installed on the torque arm at both ends of the four-point support gearbox to bear the torsion load of the gearbox. Each fan uses two sets of elastic supports, a total of four hydraulic elastic support nodes, which are cross-connected by high-pressure hoses to form two sets of hydraulic auxiliary systems. By filling antifreeze with a specific pressure, the elastic support has high torsional stiffness and low vertical stiffness. The hydraulic system provides the main stiffness, and the elastic support can absorb the vibration of the gearbox and reduce noise.

[0005] Due to the large deformation and creep characteristics of the rubber elastic body in the elastic support, the cavity inside the hydraulic elastic support will increase in volume after a period of accumulation under high load conditions, causing the pressure of the liquid filled in the cavity to drop significantly, thereby reducing the torsional stiffness of the vibration reduction system and affecting its service life. Therefore, it is necessary to regularly perform maintenance and inspection on the hydraulic elastic support and perform fluid replenishment operations. However, most wind turbines are located in remote areas or on the sea, and the hydraulic elastic support is installed in a wind turbine cabin 90 meters high, which cannot be easily inspected and maintained.

[0006] Therefore, in order to solve the above technical problems, the present application proposes an elastic rubber pad powered by an accumulator and a method for using the same. Summary of the invention

[0007] In view of the deficiencies in the prior art, an object of the present invention is to provide an elastic rubber pad powered by an accumulator and a method for using the same.

[0008] To achieve the above object, the present invention provides the following technical solution: an elastic rubber pad powered by an accumulator, comprising an elastic rubber pad body supporting a gear box, a pressure control flow assembly interconnected with the interior of the elastic rubber pad body installed on one side of the elastic rubber pad body close to the bottom portion, and the elastic rubber pad powered by an accumulator further comprises:

[0009] An accumulator assembly comprises an accumulator base, a ball accumulator is inserted and screwed on the top of the accumulator base, and the interior of the ball accumulator is connected to the pressure flow control assembly through the accumulator base and a connecting pipe;

[0010] The oil supply control device is arranged on the pressure control flow assembly to accurately control the flow of hydraulic oil from the accumulator assembly into and out of the elastic rubber pad body through the connecting pipe and the pressure control flow assembly.

[0011] Preferably, assembly bolts A are provided through the four corners of the upper surface of the accumulator base, and a plurality of assembly bolts B are provided in annular shapes equidistantly on the outer sides of the top and bottom surfaces of the elastic rubber pad body.

[0012] Preferably, a sealing port is provided on the other side of the elastic rubber pad body close to the bottom portion, and an oblique liquid injection port is provided on the elastic rubber pad body at the lateral oblique side portion of the sealing port, and the liquid injection port and the sealing port are communicated with each other. The accumulator base is a hollow rectangular hard base, and a connection interface is provided at the center of the top surface of the accumulator base. A sealing port is provided at the top of the spherical accumulator, and a connection port adapted to the connection interface is provided at the bottom end of the spherical accumulator, and the internal pressure of the spherical accumulator is greater than the internal pressure of the elastic rubber pad body.

[0013] Preferably, the pressure control flow component includes a pressure detector arranged at the side end of the elastic rubber pad body to detect the internal pressure of the elastic rubber pad body. A valve is installed in the pressure detector, and the connection or closure of the connecting pipe is controlled by the valve. The connecting pipe is a flexible high-strength hose, and a steel wire is embedded on the inner side of the surface of the connecting pipe. The pressure detector is an electronic pressure detector, and the valve is a high-pressure valve. The electronic pressure detector can accurately measure the pressure changes in the elastic rubber pad. Compared with the traditional mechanical pressure detector, the electronic pressure detector has higher measurement accuracy and stability.

[0014] Preferably, the elastic rubber pad main body and the accumulator assembly are respectively arranged on a mounting seat A and a mounting seat B, and the two are connected together by a connecting structure, and the distance between the two is adjustable. The top of the mounting seat A is located on both sides of the elastic rubber pad main body and is fixedly connected with a guide rail A. The surface of the guide rail A is slidably connected with a slider A. The top of the slider A is fixed to the lifting platform through a vertical rod, and the bottom of the lifting platform is fixed to the top of the elastic rubber pad main body, and can be installed as a whole, making the installation more stable.

[0015] Preferably, a screw rod A is detachably connected to the side of the mounting seat A opposite to the mounting seat B, and a sliding block is fixedly connected to the end of the screw rod A. A groove for the sliding block to slide is provided on the side of the mounting seat B opposite to the mounting seat A. An L-shaped plate is welded to the side end of the mounting seat B. A through hole A for the screw rod A to pass through is provided inside the L-shaped plate. The outer side walls of the screw rod A are located on both sides of the L-shaped plate and are threadedly connected with nuts A, so that the distance between the elastic rubber pad body and the accumulator assembly can be flexibly adjusted according to different installation environments.

[0016] Preferably, a connecting groove seat is welded on the side end of the mounting seat A, and a protrusion that can be inserted into the connecting groove seat is fixedly connected to the head of the screw A. Through holes B for screws to pass through are provided around the connecting groove seat, and screw holes for screw installation are provided around the protrusion. The head of the connecting pipe is detachably connected to the pressure control flow component through a flange, and the L-shaped plate is detachably connected to the side end of the mounting seat B through screws. The screw A and the L-shaped plate can be removed from the mounting seat A and the mounting seat B, so that the mounting seat A and the mounting seat B can be separated. In the event of a failure, it is convenient to remove the elastic rubber pad body or the accumulator assembly separately for replacement.

[0017] Preferably, it also includes a screw rod B welded at a suitable position around the bottom of the gear box, through holes C for the screw rod B to pass through are opened around the top of the lifting platform, and the bottom of the lifting platform is fixedly connected with a guide rail B for the sliding block B to slide at a position next to the through hole C, and a bearing is fixedly connected to the surface of the slider B, and a rotating rod is fixedly connected to the inner ring of the bearing, and the top ends of the rotating rod are fixed to the nut B through round rods. In this way, the nut B will not fall off the lifting platform, which can avoid the loss of the nut B. At the same time, there is no need to align the nut B, which is more convenient to operate.

[0018] Wherein, the oil supply control device includes:

[0019] Power module: used to supply power to other modules of the fuel supply control device;

[0020] Microprocessor control module: When the pressure detector detects that the pressure value of the elastic rubber pad exceeds the set range or returns to the set range, it will send a signal to the microprocessor control module, and the microprocessor control module will send a signal to the drive module to control the valve to open or close according to the signal;

[0021] Drive module: controls the opening or closing of the valve according to the signal sent by the microprocessor control module.

[0022] The method of using the elastic rubber pad for energy supply of the accumulator comprises the following steps:

[0023] Step 1: First, connect the connecting pipe 3 and the pressure control flow component 2 through the flange, then insert the sliding block at the head of the screw rod A on the mounting seat A into the groove on the mounting seat B, pull the mounting seat A and the mounting seat B back and forth to adjust the distance between the two, and the sliding block moves linearly along the inside of the groove to maintain the relative linear movement of the mounting seat A and the mounting seat B. At the same time, the screw rod A moves linearly back and forth along the through hole A on the L-shaped plate to adjust the distance between the mounting seat A and the mounting seat B. After the distance adjustment is completed, turn the two nuts A, and the nuts A move along the screw rod A, so that the nuts A press against the front and rear sides of the L-shaped plate to fix the distance between the mounting seat A and the mounting seat B;

[0024] Step 2: Install the overall structure formed by the mounting seat A and the mounting seat B in a suitable position; face the screw rod B at the bottom of the gear box to the through hole C on the lifting platform, and then insert it. After the insertion is completed, push the bearing to move upward, and the bearing drives the slider B to move upward. The slider B slides upward along the guide rail B to maintain the linear movement of the bearing, so that the bearing drives the nut B to move vertically upward through the rotating rod. The nut B moves upward and is close to the end of the screw rod B. Then, turn the nut B and install it on the screw rod. The nut B moves upward along the screw rod B and slowly presses against the bottom of the lifting platform, thereby fixing the gear box on the lifting platform;

[0025] Step 3: In the initial state, the internal pressure of the ball accumulator is greater than the internal pressure of the elastic rubber pad body. When in use, just install the gear box on the top surface of the elastic rubber pad body. When the pressure of the elastic rubber pad body is high, the pressure detector detects that the pressure of the elastic rubber pad body is higher than the set value, and opens the valve on the pressure detector through the oil supply control device, so that the pressure hydraulic oil inside the ball accumulator flows from the ball accumulator into the elastic rubber pad body, thereby ensuring its support;

[0026] Step 4: When the pressure of the elastic rubber pad body is low, the pressure detector detects that the pressure of the elastic rubber pad body is lower than the normal value, and opens the valve on the pressure detector through the oil supply control device, so that the pressure hydraulic oil inside the ball accumulator flows from the elastic rubber pad body into the ball accumulator, thereby ensuring its elasticity;

[0027] Step 5: When the pressure of the elastic rubber pad body gradually decreases or increases to within the set normal range under the action of the ball accumulator, the pressure detector will detect it and close the valve through the oil supply control device;

[0028] Among them, there are two important formulas involved in the oil supply control device:

[0029] (1) Pressure change formula:

[0030] ΔP = P_t - P_0, where ΔP represents the pressure change, P_t represents the current pressure value, and P_0 represents the initial pressure value.

[0031] (2) Accumulator energy formula:

[0032] E = 0.5×P×V, where E represents the energy of the ball accumulator, P represents the internal pressure of the ball accumulator, and V represents the volume of the ball accumulator.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] 1. When the pressure detector of the present invention detects that the pressure of the elastic rubber pad body is lower than the normal value, the valve on the pressure detector will be opened through the oil supply control device, so that the pressure hydraulic oil inside the ball accumulator flows from the inside of the elastic rubber pad into the ball accumulator, thereby ensuring its elasticity. When the pressure of the elastic rubber pad body is gradually reduced or increased to a set normal range under the action of the ball accumulator, the pressure detector will close the valve through the oil supply control device after detecting it, so that the hydraulic oil inside the elastic rubber pad deformed by pressure can be stored in the accumulator assembly, thereby protecting the elastic rubber pad from overload, and the accumulator can also play a role in supplying energy to the elastic rubber pad to ensure sufficient internal pressure. In summary, the present invention can, to a certain extent, avoid the effect of the cavity volume increasing after a period of accumulation under high load conditions, so as to avoid failures, reduce manual inspection and maintenance, and solve the problem that most wind turbines in the background technology are located in remote areas or on the sea, and the hydraulic elastic support is installed in a wind turbine cabin at a height of 90 meters, which cannot be conveniently inspected and maintained;

[0035] 2. The present invention connects the elastic rubber pad body and the accumulator assembly together through the mounting seat A and the mounting seat B, so that they can be installed as a whole during installation, making the installation more stable;

[0036] 3. The screw rod A and the L-shaped plate of the present invention can be removed from the mounting seat A and the mounting seat B, so that the mounting seat A and the mounting seat B can be separated. When a failure occurs, it is convenient to remove the elastic rubber pad body or the accumulator assembly separately for replacement;

[0037] 4. The present invention installs the gear box on the lifting platform. When the elastic rubber pad is extended and retracted during the support process, it drives the lifting platform to move up and down. The lifting platform drives the slider A to move up and down. The slider A slides up and down along the guide rail A to maintain the linear movement of the lifting platform. In this way, when the elastic rubber pad absorbs impact and vibration, the gear box is kept in linear movement through the above structure, which can effectively reduce shaking and swinging, making the gear box more stable during operation.

[0038] 5. The connecting pipe in the present invention is a flexible high-strength hose, and the inner side of the surface of the connecting pipe is provided with a steel wire embedded. The flexible hose can be bent and twisted, which is convenient for connecting various components, making the installation of the system more flexible and convenient. Since the system involves the flow of hydraulic oil, the connecting pipe needs to withstand a certain pressure. The high-strength hose can ensure that it will not break or leak under the working pressure. The purpose of the steel wire embedded is to enhance the structural strength, thereby preventing the hose from deforming, maintaining its stable shape, and ensuring the smooth flow of hydraulic oil;

[0039] 6. The valve in the present invention is a high-pressure valve that can withstand high pressure in the system, ensuring that the flow of hydraulic oil can be stably controlled when the pressure changes. When the pressure of the elastic rubber pad is too high or too low, the high-pressure valve can be accurately opened or closed to achieve pressure regulation;

[0040] 7. The present invention places the screw rod B at the bottom of the gear box against the through hole C on the lifting platform and then inserts it. After the insertion is completed, the bearing is pushed to move upward, and the bearing drives the slider B to move upward. The slider B slides upward along the guide rail B to maintain the linear movement of the bearing, so that the bearing drives the nut B to move vertically upward through the rotating rod. The nut B moves upward and is close to the end of the screw rod B. Then the nut B is rotated and installed on the screw rod. The nut B moves upward along the screw rod B and slowly presses against the bottom of the lifting platform, thereby fixing the gear box on the lifting platform. In this way, the nut B will not fall off the lifting platform, which can avoid the loss of the nut B. At the same time, there is no need to align the nut B, which is more convenient to operate.

[0055] Example 1

[0056] like Figures 1 to 3As shown, the present invention provides an elastic rubber pad powered by an accumulator, comprising an elastic rubber pad body 1 supporting a gear box, a side of the elastic rubber pad body 1 close to the bottom is provided with a pressure control flow assembly 2 which is interconnected with the inside of the elastic rubber pad body 1, the pressure control flow assembly 2 comprises a pressure detector 201 which is arranged at the side end of the elastic rubber pad body 1 to detect the internal pressure of the elastic rubber pad body 1, a valve 202 is installed in the pressure detector 201, and the connection or closing of the connecting pipe 3 is controlled by the valve 202, and the elastic rubber pad powered by the accumulator also comprises:

[0057] The accumulator assembly 4 includes an accumulator base 401, a ball accumulator 402 is inserted and tightened on the top of the accumulator base 401, the interior of the ball accumulator 402 is connected to the pressure control flow assembly 2 through the accumulator base 401 and the connecting pipe 3, the accumulator base 401 is a hollow rectangular hard base (the hard accumulator base 401 ensures that the accumulator assembly 4 has sufficient strength, and the hydraulic oil will not cause high-pressure damage to the ball accumulator 402 during the back and forth circulation process), a connection interface 403 is provided at the center of the top surface of the accumulator base 401, a sealing port 405 is provided at the top of the ball accumulator 402, and a connection port 404 adapted to the connection interface 403 is provided at the bottom of the ball accumulator 402;

[0058] The oil supply control device 5 is arranged on the pressure control flow assembly 2 to accurately control the flow of hydraulic oil from the accumulator assembly 4 to the elastic rubber pad body 1 through the connecting pipe 3 and the pressure control flow assembly 2 .

[0059] The ball accumulator 402 is installed into the connection interface 403 of the accumulator base 401 through the connection port 404 thereon. In the initial state, the internal pressure of the ball accumulator 402 is greater than the internal pressure of the elastic rubber pad body 1. When in use, it is only necessary to install the supporting force-bearing component (gear box) on the top surface of the elastic rubber pad body 1. When the pressure of the elastic rubber pad body 1 is high, the pressure detector 201 detects that the pressure of the elastic rubber pad body 1 is higher than the set value, and the valve 202 on the pressure detector 201 is opened through the oil supply control device 5, so that the pressure hydraulic oil inside the ball accumulator 402 flows from the ball accumulator 402 into the elastic rubber pad body 1 (the pressure hydraulic oil flows into the elastic rubber pad body 1 through the accumulator base 401 and the connecting pipe 3), thereby ensuring its support; when the pressure of the elastic rubber pad body 1 is low, the pressure detector 201 detects that the pressure of the elastic rubber pad body 1 is lower than the normal value, and the valve 202 on the pressure detector 201 is opened through the oil supply control device 5, so that the pressure hydraulic oil inside the ball accumulator 402 flows from the ball accumulator 402 into the elastic rubber pad body 1 The high-pressure hydraulic oil flows from the inside of the elastic rubber pad into the ball accumulator 402, thereby ensuring its elasticity. When the pressure of the elastic rubber pad body 1 gradually decreases or increases to a set normal range under the action of the ball accumulator 402, the pressure detector 201 detects it and closes the valve 202 through the oil supply control device 5. In this way, the hydraulic oil inside the elastic rubber pad that is deformed due to pressure can be stored in the accumulator assembly 4, thereby protecting the elastic rubber pad from overload, and the accumulator can also play a role in supplying energy to the elastic rubber pad to ensure sufficient internal pressure. In summary, the present invention can, to a certain extent, avoid the effect of increasing the volume of the inner cavity under high load conditions (deformed state) after a period of accumulation, so as to avoid malfunctions and reduce manual inspection and maintenance (the setting of the valve 202 and the oil supply control device 5 can accurately control the flow of hydraulic oil flowing into or out of the elastic rubber pad to ensure that its pressure is always maintained within a suitable range to ensure the stability of the support).

[0060] The specific structure of the fuel supply control device 5 is as follows: the fuel supply control device 5 includes a power supply module, a microprocessor control module and a drive module.

[0061] When in use, the power supply module is used to supply power to other modules of the oil supply control device 5. When the pressure detector 201 detects that the pressure value of the elastic rubber pad exceeds the set range or returns to the set range, it will send a signal to the microprocessor control module. The microprocessor control module sends a signal to the drive module to control the opening or closing of the valve 202 according to the signal. The drive module controls the opening or closing of the valve 202 according to the signal sent by the microprocessor control module.

[0062] Furthermore, the connecting pipe 3 is a flexible high-strength hose, and the inner side of the skin of the connecting pipe 3 is provided with a steel wire embedded, the pressure detector 201 is an electronic pressure detector 201, and the valve 202 is a high-pressure valve 202. The flexible connecting hose can adapt to different installation angles and space restrictions. In practical applications, the elastic rubber pad, the accumulator and the pressure detector 201 may be located in different positions, and the installation environment is complex and diverse. The flexible hose can be bent and twisted, which is convenient for connecting various components, making the installation of the system more flexible and convenient. Since the system involves the flow of hydraulic oil, the connecting pipe 3 needs to withstand a certain pressure. The high-strength hose can ensure that it will not break or leak under working pressure. The purpose of the steel wire embedded is to enhance the structural strength, thereby preventing the hose from deforming, maintaining its stable shape, and ensuring the smooth flow of hydraulic oil. The electronic pressure detector can accurately measure the pressure change in the elastic rubber pad. Compared with the traditional mechanical pressure detector, the electronic pressure detector has higher measurement accuracy and stability. The high-pressure valve 202 can withstand the high pressure in the system, ensuring that the flow of hydraulic oil can be stably controlled when the pressure changes. When the pressure of the elastic rubber pad is too high or too low, the high-pressure valve can be opened or closed accurately to achieve pressure regulation.

[0063] In addition, the elastic rubber pad body 1 is in the shape of a cylindrical rubber pad. The cylindrical design enables the elastic rubber pad to evenly distribute the force on the entire pad surface when it is under pressure. The ball accumulator 402 is in the shape of a vertical ball float accumulator. When the spherical shape is under internal pressure, the stress can be evenly distributed on the entire spherical surface, thereby ensuring that the ball accumulator 402 has sufficient strength so that it will not be damaged by excessive pressure during the energy storage process. A sealing port 6 is provided on the other side of the elastic rubber pad body 1 near the bottom. The elastic rubber pad body 1 is provided with an oblique liquid injection port 7 at the lateral bevel of the sealing port 6. The liquid injection port 7 is interconnected with the sealing port 6. The liquid injection port 7 is mainly used to inject hydraulic oil into the elastic rubber pad. The main function of the sealing port 6 is to ensure that the elastic rubber pad body 1 has good sealing performance at the part connected to the outside. When the elastic rubber pad is connected to the ball accumulator 402, the connecting hose and other components, the sealing port 6 prevents the leakage of hydraulic oil by using appropriate sealing materials and technologies to ensure the normal operation of the system. The interconnected design can reduce potential leakage points. Since the liquid injection port 7 and the sealing port 6 are interconnected, only one portion needs to be well sealed to ensure the sealing of both the liquid injection port 7 and the sealing port 6, thereby reducing the risk of hydraulic oil leakage.

[0064] Example 2

[0065] like Figure 1-Figure 3As shown, this embodiment provides a first installation structure of the elastic rubber pad body 1 and the accumulator assembly 4 in Embodiment 1, and assembly bolts A24 are provided through the four corners of the upper surface of the accumulator base 401, and a plurality of assembly bolts B25 are provided in an equidistant manner in a circular manner on the outer sides of the top and bottom surfaces of the elastic rubber pad body 1.

[0066] The accumulator base 401 is installed at a suitable position by means of assembly bolts A24, the elastic rubber pad body 1 is installed at a suitable position by means of assembly bolts B25 on the top and bottom surfaces thereof, and the gear box is installed thereon, so that the structure is simple and the installation is fast.

[0067] Example 3

[0068] like Figure 4-Figure 6 as well as Figure 8 As shown, this embodiment provides a second installation structure of the elastic rubber pad main body 1 and the accumulator assembly 4 in Embodiment 1. The elastic rubber pad main body 1 and the accumulator assembly 4 are respectively arranged on the mounting seat A8 and the mounting seat B9, and the two are connected together through a connecting structure, and the distance between the two is adjustable.

[0069] In this embodiment, the elastic rubber pad main body 1 and the accumulator assembly 4 are connected together through the mounting seat A8 and the mounting seat B9, so that they can be installed as a whole during installation, making the installation more stable (for example, the rubber pad main body and the accumulator assembly 4 originally have only four mounting parts, but when assembled together, they have eight parts, which greatly increases the number of connection points with the installation base to cope with working environments with large vibrations), and at the same time, the distance between the elastic rubber pad main body 1 and the accumulator assembly 4 can be flexibly adjusted according to different installation environments.

[0070] The specific connection structure is as follows: a screw rod A14 is detachably connected to the side of the mounting seat A8 opposite to the mounting seat B9, and a sliding block 15 is fixedly connected to the end of the screw rod A14, a groove 16 for the sliding block 15 to slide is provided on the side of the mounting seat B9 opposite to the mounting seat A8, an L-shaped plate 17 is welded to the side end of the mounting seat B9, a through hole A18 is provided inside the L-shaped plate 17 for the screw rod A14 to pass through, and nuts A19 are threadedly connected to the outer walls of the screw rod A14 on both sides of the L-shaped plate 17.

[0071] When adjusting the distance between the mounting seat A8 and the mounting seat B9, first insert the sliding block 15 at the head of the screw rod A14 on the mounting seat A8 into the groove 16 on the mounting seat B9 (it should be noted that the cross section of the sliding block 15 is the same as the internal cross section of the groove 16, and the sliding block 15 can move linearly along the inside of the groove 16), pull the mounting seat A8 and the mounting seat B9 back and forth to adjust the distance between the two, and the sliding block 15 moves linearly along the inside of the groove 16 to maintain the relative linear movement of the mounting seat A8 and the mounting seat B9 (thereby ensuring the installation The bottom surfaces of the mounting seat A8 and the mounting seat B9 are flush for easy installation). The screw rod A14 moves back and forth along the through hole A18 on the L-shaped plate 17 to adjust the distance between the mounting seat A8 and the mounting seat B9. After the distance adjustment is completed, the two nuts A19 are rotated, and the nuts A19 move along the screw rod A14 so that the nuts A19 are against the front and rear sides of the L-shaped plate 17 to fix the distance between the mounting seat A8 and the mounting seat B9, thereby adaptively adjusting the distance between the mounting seat A8 and the mounting seat B9 according to different installation environments.

[0072] Furthermore, a connecting groove seat 20 is welded on the side end of the mounting seat A8, a protrusion 21 that can be inserted into the connecting groove seat 20 is fixedly connected to the head of the screw A14, through holes B22 for screws to pass through are provided around the connecting groove seat 20, screw holes 23 for screw installation are provided around the protrusion 21, the head of the connecting pipe 3 is detachably connected to the pressure control flow component 2 through a flange, and the L-shaped plate 17 is detachably connected to the side end of the mounting seat B9 through screws.

[0073] In this way, the screw rod A14 and the L-shaped plate 17 can be removed from the mounting seat A8 and the mounting seat B9, so that the mounting seat A8 and the mounting seat B9 can be separated. In the event of a failure, it is convenient to remove the elastic rubber pad body 1 or the accumulator assembly 4 separately for replacement. When the screw rod A14 is installed, the protrusion 21 at the end thereof is inserted into the connecting groove seat 20. After the insertion is completed, the screw hole 23 and the through hole B22 are just aligned, and the screw can be passed through the through hole B22 of the connecting groove seat 20, and then the installation is turned clockwise. The protrusion 21 can be fixed in the connecting groove seat 20 by inserting it into the screw hole 23 on the protrusion 21. Then, the screw rod is passed through the L-shaped plate 17, and the L-shaped plate 17 is installed on the side end of the mounting seat B9 by the screw. Then, the distance between the above-mentioned mounting seat A8 and the mounting seat B9 can be adjusted. Conversely, the two screws are removed, and then the protrusion 21 is pulled out of the connecting groove seat 20, and the bolts on the flange are removed. The pressure control flow component 2 and the connecting pipe 3 are separated, and the mounting seat A8 and the mounting seat B9 can be separated.

[0074] Example 4

[0075] like Figure 4-Figure 7As shown, this embodiment is improved on the basis of embodiment 1, the top of the mounting seat A8 is located on both sides of the elastic rubber pad body 1 and is fixedly connected to the guide rail A10, the surface of the guide rail A10 is slidably connected to the slider A11, the top of the slider A11 is fixed to the lifting platform 13 through the vertical rod 12, and the bottom of the lifting platform 13 is fixed to the top of the elastic rubber pad body 1, that is, the gear box is installed on the lifting platform 13, when the elastic rubber pad is extended and retracted during the support process, it will drive the lifting platform 13 to move up and down, and the lifting platform 13 drives the slider A11 to move up and down, and the slider A11 slides up and down along the guide rail A10 to maintain the linear movement of the lifting platform 13, so that when the elastic rubber pad absorbs impact and vibration, the gear box is kept in linear movement through the above structure, which can effectively reduce shaking and swinging, and make the gear box more stable during operation.

[0076] Furthermore, it also includes screws B26 welded at appropriate positions around the bottom of the gearbox, through holes C27 for the screws B26 to pass through are opened around the top of the lifting platform 13, and the bottom of the lifting platform 13 is located next to the through hole C27. A guide rail B28 for the slider B29 to slide is fixedly connected, and a bearing 30 is fixedly connected to the surface of the slider B29. A rotating rod 31 is fixedly connected to the inner ring of the bearing 30. The top ends of the rotating rod 31 are fixed to the nuts B33 through round rods 32. During installation, the screw B26 at the bottom of the gearbox is facing the through hole C27 on the lifting platform 13, and then inserted. After the insertion is completed, the bearing 30 is pushed to move upward, and the bearing 30 drives the slider B29 to move upward, and the slider B29 moves upward along the guide rail B28. Slide to maintain the linear movement of the bearing 30, so that the bearing 30 drives the nut B33 to move vertically upward through the rotating rod 31, and the nut B33 moves upward to fit the end of the screw rod B26, and then the nut B33 is rotated (when the nut B33 is rotated, the nut B33 drives the rotating rod 31 to rotate through the round rod 32, and the rotating rod 31 drives the inner ring of the bearing 30 to rotate, and the inner ring of the bearing 30 rotates along its outer ring), and the nut B33 is installed on the screw rod. The nut B33 moves upward along the screw rod B26 and slowly presses against the bottom of the lifting platform 13, thereby fixing the gear box on the lifting platform 13, so that the nut B33 will not be separated from the lifting platform 13, which can avoid the loss of the nut B33. At the same time, there is no need to align the nut B33, which is more convenient to operate.

[0077] The present invention also provides a method for using the above-mentioned elastic rubber pad based on energy supply by the accumulator (when the second installation structure is used):

[0078] Step 1: First, connect the connecting pipe 3 and the pressure control flow assembly 2 through the flange plate, then insert the sliding block 15 at the head of the screw rod A14 on the mounting seat A8 into the groove 16 on the mounting seat B9, pull the mounting seat A8 and the mounting seat B9 back and forth to adjust the distance between the two, and the sliding block 15 moves linearly along the inside of the groove 16 to maintain the relative linear movement of the mounting seat A8 and the mounting seat B9. At the same time, the screw rod A14 moves linearly back and forth along the through hole A18 on the L-shaped plate 17 to adjust the distance between the mounting seat A8 and the mounting seat B9. After the distance adjustment is completed, turn the two nuts A19, and the nuts A19 move along the screw rod A14 so that the nuts A19 abut against the front and rear sides of the L-shaped plate 17 to fix the distance between the mounting seat A8 and the mounting seat B9;

[0079] Step 2: Install the overall structure formed by the mounting seat A8 and the mounting seat B9 at a suitable position; face the screw rod B26 at the bottom of the gear box to the through hole C27 on the lifting platform 13, and then insert it. After the insertion is completed, push the bearing 30 to move upward, and the bearing 30 drives the slider B29 to move upward. The slider B29 slides upward along the guide rail B28 to maintain the linear movement of the bearing 30, so that the bearing 30 drives the nut B33 to move vertically upward through the rotating rod 31. The nut B33 moves upward and is close to the end of the screw rod B26. Then, the nut B33 is rotated and installed on the screw rod. The nut B33 moves upward along the screw rod B26 and slowly presses against the bottom of the lifting platform 13, thereby fixing the gear box on the lifting platform 13;

[0080] Step 3: In the initial state, the internal pressure of the ball accumulator 402 is greater than the internal pressure of the elastic rubber pad body 1. When in use, the gear box only needs to be installed on the top surface of the elastic rubber pad body 1. When the pressure of the elastic rubber pad body 1 is high, the pressure detector 201 detects that the pressure of the elastic rubber pad body 1 is higher than the set value, and the valve 202 on the pressure detector 201 is opened through the oil supply control device 5, so that the pressure hydraulic oil inside the ball accumulator 402 flows from the ball accumulator 402 into the elastic rubber pad body 1, thereby ensuring its support;

[0081] Step 4: When the pressure of the elastic rubber pad body 1 is low, the pressure detector 201 detects that the pressure of the elastic rubber pad body 1 is lower than the normal value, and opens the valve 202 on the pressure detector 201 through the oil supply control device 5, so that the pressure hydraulic oil inside the ball accumulator 402 flows from the elastic rubber pad body 1 into the ball accumulator 402, thereby ensuring its elasticity;

[0082] Step 5: When the pressure of the elastic rubber pad body 1 gradually decreases or increases to within the set normal range under the action of the ball accumulator 402, the pressure detector 201 detects it and closes the valve 202 through the oil supply control device 5;

[0083] Among them, the fuel supply control device 5 (microprocessor control module) involves two important formulas:

[0084] (1) Pressure change formula:

[0085] ΔP = P_t - P_0, where ΔP represents the pressure change, P_t represents the current pressure value, and P_0 represents the initial pressure value. This formula can be used to calculate the pressure change of the elastic rubber pad body 1 to determine whether the valve 202 needs to be opened or closed.

[0086] (2) Accumulator energy formula:

[0087] E = 0.5×P×V, where E represents the energy of the ball accumulator 402, P represents the internal pressure of the ball accumulator 402, and V represents the volume of the ball accumulator 402. This formula can help determine the energy stored in the ball accumulator 402 under different pressures, thereby accurately controlling the opening degree of the valve 202 (controlling the speed of the flow of the pressure hydraulic oil) to better protect the elastic rubber pad body 1.

[0088] The elastic rubber pad based on energy supply by an accumulator and the use method thereof of the present invention have the following advantages:

[0089] To a certain extent, it can prevent the cavity inside the elastic rubber pad from increasing in volume after a period of accumulation under high load conditions, thereby avoiding failures and reducing manual inspection and maintenance;

[0090] The elastic rubber pad body 1 and the accumulator assembly 4 are connected together through the mounting seat A8 and the mounting seat B9, so that they can be installed as a whole during installation, making the installation more stable;

[0091] The screw rod A14 and the L-shaped plate 17 can be removed from the mounting seat A8 and the mounting seat B9, so that the mounting seat A8 and the mounting seat B9 can be separated. In the event of a failure, it is convenient to remove the elastic rubber pad body 1 or the accumulator assembly 4 separately for replacement;

[0092] The gearbox is mounted on the lifting platform 13. When the elastic rubber pad is extended and retracted during the supporting process, the lifting platform 13 is driven to move up and down. The lifting platform 13 drives the slider A11 to move up and down. The slider A11 slides up and down along the guide rail A10 to maintain the linear movement of the lifting platform 13. In this way, when the elastic rubber pad absorbs shock and vibration, the gearbox is kept moving linearly through the above structure, which can effectively reduce shaking and swinging, making the gearbox more stable during operation.

[0093] The connecting pipe 3 is a flexible high-strength hose, and the inner side of the skin of the connecting pipe 3 is provided with a steel wire embedded. The flexible hose can be bent and twisted, which is convenient for connecting various components, making the installation of the system more flexible and convenient. Since the system involves the flow of hydraulic oil, the connecting pipe 3 needs to withstand a certain pressure. The high-strength hose can ensure that it will not break or leak under the working pressure. The purpose of the steel wire embedded is to enhance the structural strength, thereby preventing the hose from deforming, maintaining its stable shape, and ensuring the smooth flow of hydraulic oil;

[0094] Valve 202 is a high-pressure valve that can withstand high pressure in the system, ensuring that the flow of hydraulic oil can be stably controlled when the pressure changes. When the pressure of the elastic rubber pad is too high or too low, the high-pressure valve 202 can be accurately opened or closed to achieve pressure regulation;

[0095] Place the screw B26 at the bottom of the gear box against the through hole C27 on the lifting platform 13, and then insert it. After the insertion is completed, push the bearing 30 to move upward, and the bearing 30 drives the slider B29 to move upward. The slider B29 slides upward along the guide rail B28 to maintain the linear movement of the bearing 30, so that the bearing 30 drives the nut B33 to move vertically upward through the rotating rod 31. The nut B33 moves upward and is close to the end of the screw B26. Then the nut B33 is rotated and installed on the screw. The nut B33 moves upward along the screw B26 and slowly presses against the bottom of the lifting platform 13, thereby fixing the gear box on the lifting platform 13. In this way, the nut B33 will not fall off the lifting platform 13, which can avoid the loss of the nut B33. At the same time, there is no need to align the nut B33, which is more convenient to operate.
