Description

Technical Field

[0001] This invention relates to the field of heavy equipment installation technology, and more specifically to a liquid lubrication translation device for heavy equipment installation and positioning. Background Technology

[0002] In industrial construction such as petrochemicals and metallurgy, large and heavy equipment is frequently used. These pieces of equipment typically weigh several tons, with some even reaching tens or hundreds of tons. Once the equipment arrives at the work site, it needs to be precisely positioned to meet subsequent installation requirements. For example, in the metallurgical industry, large steelmaking converters weighing up to hundreds of tons need to be installed. During installation, bolt tightening and hole positioning are required. For mechanical equipment requiring bolt fixing and hole positioning, the installation positioning tolerance is generally required to be within 1 mm. Ordinary handling equipment cannot meet such precision requirements.

[0003] When positioning heavy objects weighing several tons, fine-tuning with pry bars is typically used to achieve a relatively precise location. However, for industrial equipment weighing tens or hundreds of tons, positioning often requires manual labor in conjunction with a crane. While these methods can meet the required accuracy, they have several drawbacks: 1) They require repeated positioning, resulting in low efficiency; 2) They require multiple people, are time-consuming and labor-intensive, and have high costs; 3) Using pry bars can easily damage the equipment and the ground.

[0004] Based on the above background, this invention designs a liquid lubrication translation device for the installation and positioning of heavy equipment. It effectively avoids the various drawbacks of traditional manual positioning and can meet the requirements of higher precision positioning, providing a new idea and method for the precise positioning of large and heavy equipment. Summary of the Invention

[0005] The invention proposes a liquid lubrication translation device for the installation and positioning of heavy equipment, which solves the problem of difficulty in installing and positioning large heavy equipment at the work site. The application of this device can improve the installation and positioning accuracy and efficiency of large heavy equipment.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A liquid lubrication translation device for installation and positioning of heavy equipment includes a first servo motor propulsion unit, a housing unit, and a moving platform. The first servo motor propulsion unit is mounted on the housing unit and is used to drive the moving platform to move.

[0008] The housing unit includes a housing, on which multiple hydraulic oil inlets are provided for hydraulic oil to enter the housing and lift the mobile platform.

[0009] The first servo motor propulsion unit includes first servo motors symmetrically installed on both sides of the housing. The first servo motors are connected to lead screws via couplings. A slider is sleeved on the lead screw, and the slider is slidably connected to the moving platform. The lead screw is inserted into the moving platform.

[0010] As a further aspect of the present invention: the mobile platform includes an upper platform, a lower push block is fixedly installed at the bottom of the upper platform, a lead screw hole for lead screw insertion is provided on the lower push block, a plug block is fixedly installed above the lead screw hole, and the plug block has a sliding groove on the slider.

[0011] As a further aspect of the present invention: the horizontal surface area of ​​the upper platform is greater than the horizontal surface area of ​​the lower push block, and the lower end of the upper platform is placed on the surface of the box.

[0012] As a further aspect of the present invention: multiple deep grooves are provided on both sides of the interior of the housing, and positioning sleeve mounting rods and positioning sleeves are installed in the deep grooves to prevent the moving platform from shifting when it slides.

[0013] As a further aspect of the present invention: several circular oil cavities are machined on the inner surface of the lower end of the housing, and each oil cavity needs to have a hydraulic channel opened inside the lower end of the housing.

[0014] As a further aspect of the present invention: the upper end of the box body has an upper groove, and each sealing gasket spring is evenly installed in the upper groove of the box body. The sealing gasket is placed on the sealing gasket spring, and the sealing gasket is tightly attached to the lower end face of the upper platform under the elastic force of the sealing gasket spring, so that a sealed space is formed inside the box body.

[0015] As a further embodiment of the present invention: a base plate is fixedly installed at the bottom of the housing, and motor mounting plates are installed on both sides of the base plate. A second servo motor is installed on one of the motor mounting plates. A bidirectional lead screw is fixedly installed on the output shaft of the second servo motor. A U-shaped slider is sleeved on the bidirectional lead screw, and the top of the U-shaped slider is connected to the first servo motor.

[0016] As a further aspect of the present invention: the housing is provided with a hydraulic oil outlet and a motor shaft mounting hole.

[0017] As a further aspect of the present invention: the working process of the liquid lubrication translation device is as follows:

[0018] Step 1: Install a level sensor on the upper platform. When the device is working, the level sensor will constantly detect the levelness of the upper platform.

[0019] Step 2: The hydraulic power system controls each hydraulic pipeline. When the equipment starts working, the hydraulic power system controls each hydraulic pipeline to open the flow control valve switch and continuously introduces a certain amount of hydraulic oil into the pipeline. The fluid model of each circular oil chamber of this device conforms to the parallel disk gap flow in fluid mechanics. The force of the hydraulic oil on the moving platform and the distance that the hydraulic oil lifts the moving platform satisfy the following formula:

[0020]

[0021] Where F is the force exerted by the hydraulic oil on the moving platform; r1 is the radius of the hydraulic channel leading into the circular oil cavity; R is the radius of the circle formed by the circular oil cavity; q V is the inlet flow rate; h is the distance the hydraulic oil lifts the mobile platform; μ is the dynamic viscosity coefficient;

[0022] Step 3: When the hydraulic oil fills the circular oil chamber, the moving platform moves a distance in the vertical direction under the force of the hydraulic oil in each circular oil chamber, so that when the lower end face of the lower push block moves with the inner surface of the lower part of the box, it becomes liquid sliding friction.

[0023] Step 4: If the device to be adjusted needs to be positioned to the left, the command to adjust the positioning to the left is transmitted to the industrial controller. The industrial controller controls the first servo motor propulsion unit to start the first servo motors at both ends, so that the two first servo motors work in sync and propel the moving platform to the left at a uniform speed.

[0024] Step 5: During the leftward translation of the mobile platform, the device to be adjusted needs to be moved to the left as a whole, with the center of gravity shifting to the left.

[0025] Step 6: If the level sensor detects that the moving platform is tilted to the left, the sensor will transmit the detected data to the industrial controller. The industrial controller will control the hydraulic power system, and the hydraulic power system will control the flow control valves of each pipeline to adjust the flow, so that the force of the hydraulic oil on the moving platform in each hydraulic pipeline is balanced, so that the moving platform returns to the level position until it reaches the designated position.

[0026] Step 7: When the target position is almost reached, the industrial controller controls the first servo motor propulsion unit to stop the first servo motor from working, thus completing the positioning.

[0027] The beneficial effects of this invention are:

[0028] (1) It can achieve precise positioning of large and heavy equipment;

[0029] (2) High positioning efficiency, no need for repeated positioning;

[0030] (3) The equipment is easy to use and can be operated by one or two people, saving time and effort and reducing equipment positioning costs. Attached Figure Description

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figure 1-2 As shown, the present invention is a liquid lubrication translation device for installation and positioning of heavy equipment, including a first servo motor propulsion unit, a housing unit and a moving platform 9. The first servo motor propulsion unit is disposed on the housing unit and is used to drive the moving platform 9 to move.

[0044] The housing unit includes a housing 8, which has multiple hydraulic oil inlets 803 for hydraulic oil to enter the housing 8 and lift the moving platform 9. The hydraulic oil is continuously pumped into the circular oil chamber 805. Under the pressure of the hydraulic oil, the moving platform 9 is lifted a certain distance. The flow control valve controls the force and lifting distance on the moving platform by controlling the hydraulic oil inlet volume. The hydraulic oil fills the two contact surfaces, so that the contact surfaces form liquid sliding friction.

[0045] Please see Figure 3-8 As shown, the first servo motor propulsion unit includes a first servo motor 1 symmetrically installed on both sides of the housing 8. The first servo motor 1 is connected to the lead screw 4 through a coupling 2. The lead screw 4 is tightly fitted with the cylindrical roller bearing 3. A slider 5 is sleeved on the lead screw 4. The slider 5 is slidably connected to the moving platform, and the lead screw 4 is inserted into the moving platform 9.

[0046] The mobile platform 9 includes an upper platform 901, and a lower push block 902 is fixedly installed at the bottom of the upper platform 901. The lower push block 902 has a lead screw hole 904 for inserting a lead screw 4. The diameter of the lead screw hole 904 is larger than the diameter of the lead screw 4. A plug-in block 903 is fixedly installed above the lead screw hole 904. The plug-in block 903 and the slide groove 501 opened on the slider 5 are connected.

[0047] A base plate 121 is fixedly installed at the bottom of the housing 8. Motor mounting plates 122 are installed on both sides of the base plate 121. A second servo motor 123 is installed on one of the motor mounting plates 122. A bidirectional lead screw 124 is fixedly installed on the output shaft of the second servo motor 123. A U-shaped slider 125 is sleeved on the bidirectional lead screw 124. The top of the U-shaped slider 125 is connected to the first servo motor 1.

[0048] Before placing the mobile platform 9 into the housing 8, the second servo motor 123 is started first, which drives the U-shaped slider 125 to move through the bidirectional lead screw 124, thereby driving the first servo motor 1 to move to both sides, and then driving the lead screw 4 and slider 5 to move to both sides. Then the mobile platform 9 is placed into the housing 8. At this time, the lead screw 4 and slider 5 are started again to reset. The lead screw 4 is inserted into the lead screw hole 904, and the sliding groove 501 on the slider 5 contacts the plug block 903.

[0049] Then, hydraulic oil is pumped into the housing 8 to lift the moving platform 9 slightly. Then, the first servo motor 1 is started to drive the lead screw 4 to rotate, which in turn drives the U-shaped slider 125 to move, thereby pushing the moving platform 9 to move left and right.

[0050] The horizontal surface area of ​​the upper platform 901 is larger than that of the lower push block 902, and the lower end of the upper platform 901 rests on the surface of the housing 8. When not in operation, the lower end face of the lower push block 902 is in contact with the lower inner surface of the housing 8, and the two surfaces are separated by hydraulic oil when in operation.

[0051] Multiple deep grooves are provided on both sides of the interior of the housing 8. A positioning sleeve mounting point 806 is installed in the deep groove. A positioning sleeve mounting rod 7 and a positioning sleeve 6 are installed in the positioning sleeve mounting point 806 to prevent the moving platform 9 from shifting when it slides.

[0052] Several circular oil cavities 805 are machined on the inner surface of the lower end of the housing 8, and each oil cavity needs to have a hydraulic channel opened inside the lower end of the housing 8.

[0053] The upper end of the housing 8 has an upper groove 804. Each sealing washer spring 11 is evenly installed in the upper groove 804. The sealing washer 10 is placed on the sealing washer spring 11. Under the elastic force of the sealing washer spring 11, the sealing washer 10 is tightly attached to the lower end face of the upper platform 901, so that the inside of the housing 8 forms a sealed space to prevent the internal hydraulic oil from being contaminated when the equipment is working.

[0054] The housing 8 is provided with a hydraulic oil outlet 801 and a motor shaft mounting hole 802.

[0055] Example 2

[0056] See Figure 1-8 As shown, the working process of this liquid lubrication translation device is as follows:

[0057] Step 1: Install a level sensor on the upper stage 901. When the device is working, the level sensor will constantly detect the levelness of the upper stage 901.

[0058] Step 2: The hydraulic power system controls each hydraulic pipeline. When the equipment starts working, the hydraulic power system controls each hydraulic pipeline to open the flow control valve switch and continuously introduces a certain amount of hydraulic oil into the pipeline. The fluid model of each circular oil chamber of this device conforms to the parallel disk gap flow in fluid mechanics. The force of the hydraulic oil on the moving platform and the distance that the hydraulic oil lifts the moving platform satisfy the following formula:

[0059]

[0060] Where F is the force exerted by the hydraulic oil on the moving platform; r1 is the radius of the hydraulic channel leading into the circular oil cavity; R is the radius of the circle formed by the circular oil cavity; q V is the inlet flow rate; h is the distance the hydraulic oil lifts the mobile platform; μ is the dynamic viscosity coefficient;

[0061] Step 3: When the hydraulic oil fills the circular oil chamber, the moving platform moves a distance in the vertical direction under the force of the hydraulic oil in each circular oil chamber, so that when the lower end face of the lower push block moves with the inner surface of the lower part of the box, it becomes liquid sliding friction.

[0062] Step 4: If the device to be adjusted needs to be positioned to the left, the command to adjust the positioning to the left is transmitted to the industrial controller. The industrial controller controls the first servo motor propulsion unit to start the first servo motors at both ends, so that the two first servo motors work in sync and propel the moving platform to the left at a uniform speed.

[0063] Step 5: During the leftward translation of the mobile platform, the device to be adjusted needs to be moved to the left as a whole, with the center of gravity shifting to the left.

[0064] Step 6: If the level sensor detects that the moving platform is tilted to the left, the sensor will transmit the detected data to the industrial controller. The industrial controller will control the hydraulic power system, and the hydraulic power system will control the flow control valves of each pipeline to adjust the flow, so that the force of the hydraulic oil on the moving platform in each hydraulic pipeline is balanced, so that the moving platform returns to the level position until it reaches the designated position.

[0065] Step 7: When the target position is almost reached, the industrial controller controls the first servo motor propulsion unit to stop the first servo motor from working, thus completing the positioning.

[0066] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
