Description

Technical Field

[0001] The invention relates to the technical field of heavy equipment installation, and in particular to a liquid lubrication translation device for installation and positioning of heavy equipment. Background Art

[0002] In the construction of industries such as petrochemicals and metallurgy, large and heavy equipment is often used. The weight of these large and heavy equipment is generally more than several tons, and some can even reach dozens or hundreds of tons. When the equipment arrives at the work site, it needs to be accurately positioned to meet its later installation requirements. For example, in the metallurgical industry, it is necessary to install a large steelmaking converter, which weighs up to hundreds of tons. When installing it, it is necessary to tighten the bolts and locate the holes. For mechanical equipment that requires bolt fixing and hole positioning, the installation positioning tolerance is generally required to be within 1mm, and ordinary handling equipment cannot meet such precision requirements.

[0003] When positioning a heavy object weighing several tons, a crowbar is usually used to fine-tune the equipment to achieve a relatively precise position; when positioning industrial equipment weighing tens or hundreds of tons, it often requires manual and crane coordination. Although the above equipment positioning methods can also meet the requirements of positioning accuracy, there are many disadvantages: 1) Positioning needs to be repeated many times, and the positioning efficiency is low; 2) Positioning requires the assistance of multiple people, which is time-consuming and labor-intensive, and the positioning cost is high; 3) Workers using crowbars to position are likely to cause damage to the equipment and the ground.

[0004] Based on the above background, the present invention designs a liquid lubrication translation device for heavy equipment installation and positioning, which not only effectively avoids the various disadvantages of traditional manual positioning, but also meets the requirements of higher precision positioning, providing a new idea and method for the precise positioning of large heavy equipment. Summary of the invention

The application of this device can improve the installation and positioning accuracy and efficiency of large heavy equipment.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A liquid lubrication translation device for installation and positioning of heavy equipment comprises a first servo motor propulsion unit, a box unit and a mobile platform, wherein the first servo motor propulsion unit is arranged on the box unit and is used to drive the mobile platform to move;

[0008] The box unit comprises a box, and a plurality of hydraulic oil inlets are provided on the box for the hydraulic oil to enter the box to lift the mobile platform;

[0009] The first servo motor propulsion unit includes a first servo motor symmetrically installed on both sides of the box, the first servo motor is connected to the lead screw through a coupling, a slider is sleeved on the lead screw, the slider is connected to the mobile platform for up and down sliding, and the lead screw is inserted into the mobile platform.

[0010] As a further solution of the present invention: the mobile platform includes an upper loading platform, a lower pushing block is fixedly installed on the bottom of the upper loading platform, a screw hole for inserting a screw is opened on the lower pushing block, a plug-in block is fixedly installed above the screw hole, and the plug-in block is connected to a sliding groove opened on the slider.

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

[0012] As a further solution of the present invention: a plurality of deep grooves are provided on both sides of the interior of the box body, and positioning sleeve mounting rods and positioning sleeves are installed in the deep grooves to prevent the mobile platform from deflecting when sliding.

[0013] As a further solution of the present invention: a plurality of circular oil chambers are machined on the inner surface of the lower end of the box body, and each oil chamber needs to open a hydraulic channel inside the lower end of the box body.

[0014] As a further solution of the present invention: an upper groove is opened at the upper end of the box body, 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. Under the action of the elastic force of the sealing gasket spring, the sealing gasket is tightly fitted with the lower end surface of the upper loading platform part to form a closed space inside the box body.

[0015] As a further solution of the present invention: a bottom plate is fixedly installed on the bottom of the box body, and motor mounting plates are installed on both sides of the bottom plate, one of the motor mounting plates is installed with a second servo motor, and a bidirectional screw rod is fixedly installed on the output shaft of the second servo motor, a U-shaped slider is sleeved on the bidirectional screw rod, and the top of the U-shaped slider is connected to the first servo motor.

[0016] As a further solution of the present invention: a hydraulic oil outlet and a motor shaft mounting hole are provided on the box body.

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

[0018] Step 1: Install a level sensor on the upper stage. When the device is working, the level sensor always detects the levelness of the upper stage.

[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 passes a certain amount of hydraulic oil into the pipeline. The fluid model of each circular oil cavity of the device conforms to the parallel disc gap flow in fluid mechanics. The force of the hydraulic oil on the mobile platform and the distance the hydraulic oil lifts the mobile platform satisfy the following formula:

[0020]

[0021] Where F is the force exerted by the hydraulic oil on the mobile platform; r1 is the radius of the hydraulic passage leading to the circular oil chamber; R is the radius of the circle formed by the circular oil chamber; 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 chambers, the mobile platform moves vertically under the force of the hydraulic oil in each circular oil chamber, so that the contact surface between the lower end surface of the lower push block and the lower inner surface of the box body changes into liquid sliding friction;

[0023] Step 4: If the device to be adjusted needs to be adjusted to the left, the command to adjust the position to the left is transmitted to the industrial controller, and 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 cooperate synchronously and propel the mobile platform to the left at a uniform speed;

[0024] Step 5: When the mobile platform moves to the left, the device to be adjusted needs to move to the left as a whole, and the center of gravity moves to the left;

[0025] Step 6: If the horizontal sensor detects that the mobile platform is tilted to the left, the sensor transmits the detected data to the industrial controller, and the industrial controller controls the hydraulic power system. The hydraulic power system controls the flow control valves of each pipeline to adjust the flow, so that the force of the hydraulic oil in each hydraulic pipeline on the mobile platform is balanced as a whole, so that the mobile platform returns to a horizontal position until it reaches the specified position;

[0026] Step 7: When the designated position is about to be reached, the industrial controller controls the first servo motor propulsion unit to control the first servo motor to stop working, and the positioning is now completed.

[0027] Beneficial effects of the present invention:

[0028] (1) It can realize accurate 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. BRIEF DESCRIPTION OF THE DRAWINGS
