Description

Technical Field

[0001] The invention relates to the technical field of mechanical transportation, in particular to a large-scale repair parts transfer tool based on electromechanical engineering. Background Art

[0002] In the modern industrial field, large equipment is increasingly used. For example, large generators in the energy industry, super-large reaction towers in the petrochemical industry, and large machine tools in the heavy machinery manufacturing field are constantly emerging and developing towards large-scale and precision. Traditional manual handling or simple tool handling methods can no longer meet the needs. Not only is the efficiency low, but it is also very easy to cause damage to the repair parts, affecting the equipment's repair progress and the quality of re-commissioning. With the continuous expansion of industrial production scale and the increase in the frequency of equipment maintenance, the demand for safe and efficient transfer of large repair parts has become more urgent.

[0003] In the prior art, when transferring and transporting in large maintenance rooms, the equipment only relies on simple supporting structures or single-sided or double-sided fixing methods. When the transportation vehicle accelerates, decelerates or turns, the maintenance parts will shake due to inertia and it is difficult to maintain a stable position. For example, when transporting maintenance parts such as large engine cylinders, due to the lack of all-round clamping and positioning, the cylinder may roll or tilt during the driving of the vehicle, which not only easily causes bumps and damage to the surface of the maintenance parts, affecting the quality and subsequent performance of the maintenance parts, but also damages the transportation equipment or surrounding facilities due to the sudden change in the position of the maintenance parts. In addition, some maintenance parts with complex structures and special shapes, such as curved drive shafts of large ships or uniquely shaped aircraft parts, are difficult to find suitable fixing points and stable transfer methods during long-distance transportation. Traditional equipment can often only transfer maintenance parts within a specific size range. When encountering new types of maintenance parts, it is necessary to redesign or modify the transportation equipment, which consumes a lot of time and cost, and seriously affects the efficiency of maintenance work and the production progress of the enterprise.

[0015] Compared with the prior art, the present invention provides a large-scale repair parts transfer tool based on electromechanical engineering, which has the following beneficial effects:

[0016] 1. Through the setting of the relative position fixing mechanism, under the drive of the telescopic cylinder, through the connection of the workpiece guide block and the coordinated use of the guide body and the bent connecting rod, the four positioning plates are synchronously driven to move toward the middle of the placement base to fit and move, and the repair parts are positioned during transportation to avoid affecting the relative position or state of the repair parts during transportation. The four directions move synchronously for fitting and positioning, which can provide a balanced clamping force for the repair parts and prevent the repair parts from shaking or displacement from all angles. During transportation, whether it encounters bumpy roads or sudden braking, the repair parts can be firmly fixed in the initial position to avoid collision damage caused by changes in relative positions. For example, when transporting precision large instrument repair parts, it can ensure that the internal parts are not displaced by vibration, ensure the integrity of the repair parts, and can adapt to repair parts of different shapes and sizes, with strong versatility. For regular-shaped repair parts such as rectangular blocks, they can be tightly clamped from all sides; for irregular-shaped repair parts, they can also be fitted through coordinated adjustment in four directions, which improves the adaptability of the tooling to various types of repair parts.

[0017] 2. By setting the buffer spring, when the relative position of the maintenance parts is adjusted during the centering and positioning auxiliary transportation process, the impact force generated instantly during the transportation process can be effectively absorbed to prevent the maintenance parts from being deformed, broken or damaged due to the instantaneous excessive force, and to avoid the instantaneous impact force from damaging the sensitive components inside the maintenance parts. Furthermore, the buffer spring can balance the clamping force during the clamping process in four directions. Due to the elastic characteristics of the buffer spring, when the clamping force in one direction is too large, the buffer spring will be compressed more, thereby increasing the clamping force in other directions accordingly to keep the force on the maintenance parts balanced, avoid tilting, offset or the like of the maintenance parts due to uneven force, and improve the stability of clamping and positioning.

[0018] 3. Through the setting of the special-shaped parts fitting mechanism, the hinge of multiple link blocks enables the relative position fixing mechanism to better adapt to various shapes of maintenance parts. According to the different shapes of maintenance parts, the link blocks can fit the surface of the maintenance parts by rotating and offsetting, which greatly improves the versatility of the tooling, flexibly adjusts the angle, closely fits the surface of the maintenance parts, and realizes precise positioning. For maintenance parts with uneven surfaces, the rotation offset of the hinge block can ensure that each contact point can fully fit with the maintenance parts, thereby increasing the contact area, improving the uniformity of the clamping force, and avoiding damage to the maintenance parts due to excessive local clamping force. At the same time, it can also better prevent the maintenance parts from shaking or shifting during transportation. Under the plug-in action of the magnetic column and the pin cavity, fixing the hinge position can effectively prevent the relative position of the maintenance parts from changing during transportation. When encountering bumpy roads, sudden braking or sharp turns, the maintenance parts can also be firmly fixed in the clamping mechanism and will not be displaced due to external forces, avoiding damage or loss of accuracy due to position changes.

[0038] For further examples, please refer to Figures 5 to 8 As shown:

[0039] The special-shaped part fitting mechanism 3 is used to fit according to the shapes of different special-shaped parts. The special-shaped part fitting mechanism 3 includes a U-shaped body 31. The U-shaped body 31 is mainly used to connect the positioning link block 32. The U-shaped body 31 is fixedly connected to the middle of both sides of the arc-shaped fitting plate 211. A rotating column 34 is rotatably connected in the U-shaped body 31. A plurality of through holes are provided in the outer ring of one end of the rotating column 34. The outer ring of the rotating column 34 is rotatably connected to the link block 32. The link blocks 32 are provided with a plurality of links and the link blocks 32 are rotatably connected through the rotating column 34. An air pipe 33 is slidably inserted between the link blocks 32. The air pipe 33 is connected to an external air pump. The air pipe 33 is mainly used to transport gas into the air chamber. A column cavity 35 is provided in the link block 32. A latch cavity 36 is provided on the link block 32 in the column cavity 35. The latch cavity 36 corresponds to the position of the through hole on the rotating column 34.

[0040] The special-shaped part fitting mechanism 3 also includes a piston piece 37. A spring is provided at one end of the piston piece 37 away from the auxiliary column 38 to assist the piston piece 37 in resetting. The piston piece 37 is mainly used to increase the air pressure in the air chamber and squeeze it to the position of the through hole on the rotating column 34. The piston piece 37 is slidably connected to the end of the rotating column 34 away from the through hole. The side of the piston piece 37 close to the through hole is fixedly connected to the auxiliary column 38. The outer ring of the auxiliary column 38 is fixedly connected to a plurality of electromagnetic tubes 39. The number of the electromagnetic tubes 39 is consistent with the number of through holes opened on the rotating column 34 and the positions correspond. The inner cavity of the electromagnetic tube 39 is provided with an electromagnetic block. The inner cavity of the electromagnetic tube 39 is fixedly connected to An auxiliary spring 310 is fixedly connected with a magnetic column 311 at one end of the auxiliary spring 310 away from the inner cavity of the electromagnetic tube 39. The magnetic column 311 is mainly used to fix the rotating column 34 after being inserted into the pin cavity 36 to prevent the link blocks 32 from rotating through the rotating column 34. The magnetic column 311 is slidably connected in the electromagnetic tube 39. The piston plate 37 divides the rotating column 34 into an air chamber and an activity chamber. The air supply pipe 33 is connected to the air chamber. An air outlet valve 312 is provided on the link block 32. The air outlet valve 312 is connected to the air chamber. The magnetic column 311 is slidably connected in the through hole opened on the outer ring of the rotating column 34 and the pin cavity 36.

[0041] Everything in the above example works like this:

[0042] In the initial state: the positioning plate 29 is located at the outer circle position of the placement base 1, a maintenance room is placed in the middle of the placement base 1, the piston plate 37 is at the end away from the through hole on the rotating column 34, the electromagnetic tube 39 is energized to generate magnetic attraction and adsorb to the magnetic column 311, and the magnetic column 311 is not inserted into the pin cavity 36.

[0043] The following is the working process of the relative position fixing mechanism 2 for positioning the maintenance parts at the relative position on the placement base 1 when the maintenance parts are transferred to prevent the position from being offset during long-distance transfer and transportation:

[0044] When in use, the telescopic cylinder 22 is started, and the extension rod of the telescopic cylinder 22 is retracted inwardly. Then, when the extension rod is retracted inwardly, the type guide block 28 fixed to the extension rod is pulled to move on the guide rail 27 in the direction of the guide body 23. While the type guide block 28 moves inwardly, under the connection between the type guide block 28 and the slider 25, the slider 25 is pulled to move toward the center of the placement base 1, and gradually approaches the maintenance part placed on the center surface of the placement base 1. At the same time, one end of the curved connecting rod 24 connected to the bottom of the slider 25 is synchronously deflected counterclockwise under the movement of the slider 25, and the end of the curved connecting rod 24 away from the slider 25 pushes the guide body 23 to rotate in the opposite direction under the action of this offset, thereby When the guide body 23 rotates in the reverse direction, the connection between the guide body 23 and the bent connecting rod 24 drives the four bent connecting rods 24 to deflect in the counterclockwise direction synchronously with the end connected thereto, and the slider 25 and the I-shaped guide block 28 are pulled toward the center of the placement base 1 by the bent connecting rod 24, so as to push the arc-shaped laminating plate 211 to fit with the repair part. Since the repair parts have different shapes and the elastic coefficient of the buffer spring 210 is large, after the arc-shaped laminating plate 211 fits with the repair part, the buffer spring 210 is compressed. The existence of the buffer spring 210 creates a certain buffer space between the arc-shaped laminating plate 211 and the positioning plate 29, which assists in the centering and positioning of the special-shaped repair parts during transportation and improves the handling stability.

[0045] By setting the relative position fixing mechanism 2, under the drive of the telescopic cylinder 22, through the connection of the type guide block 28 and the coordinated use of the guide body 23 and the curved connecting rod 24, the four positioning plates 29 are synchronously driven to move toward the middle of the placement base 1 to fit and move, and the repair parts are positioned during transportation to avoid affecting the relative position or state of the repair parts during transportation. The four directions move synchronously for fitting and positioning, which can provide a balanced clamping force for the repair parts and prevent the repair parts from shaking or displacement from all angles. During transportation, whether it encounters bumpy roads or sudden braking, the repair parts can be firmly fixed in the initial position to avoid collision damage caused by changes in relative positions. For example, when transporting precision large instrument repair parts, it can ensure that the internal parts are not affected by vibration and displaced, and the integrity of the repair parts is guaranteed. It can also adapt to repair parts of different shapes and sizes, with strong versatility. For regular-shaped repair parts such as rectangular parallelepiped, it can be tightly clamped from all sides; for irregular-shaped repair parts, it can also be fitted through coordinated adjustment in four directions, which improves the adaptability of tooling to various types of repair parts.

[0046] By setting the buffer spring 210, when the relative position of the repair parts is assisted in the conveying process by centering and fitting, the impact force generated instantaneously during the conveying process can be effectively absorbed to prevent the repair parts from being deformed, broken or damaged due to the instantaneous excessive force, and to avoid the instantaneous impact force from damaging the sensitive components inside the repair parts. Furthermore, the buffer spring 210 can balance the clamping force during the clamping process in four directions. Due to the elastic characteristics of the buffer spring 210, when the clamping force in one direction is too large, the buffer spring 210 will be compressed more, thereby increasing the clamping force in other directions accordingly to keep the force on the repair parts balanced, avoid tilting, offset or the like of the repair parts due to uneven force, and improve the stability of the clamping positioning.

[0047] Please refer to the above working process Figures 1 to 4 .

[0048] The following is the working process of the special-shaped part fitting mechanism 3 for fitting according to the shapes of different special-shaped parts:

[0049] When in use, while the buffer spring 210 moves in the center, through the change in the position of the buffer spring 210 and the hinged relationship between the link block 32, according to the shape of the repair part with different shapes, the link block 32 gradually fits with the surface of the repair part under the movement of the buffer spring 210, and then according to the shape and curvature of the surface of the repair part, the multiple link blocks 32 deflect to fit with the curvature of the surface of the repair part. After the buffer spring 210 and the repair part are in contact and positioned, the multiple link blocks 32 rotate to adjust the angle to fit the surface of the repair part. The air pipe 33 is pumped by an external air pump. Gas is delivered to the air chamber of the rotating column 34, and then under the action of high pressure, the piston plate 37 is pushed to move toward the end of the rotating column 34 where a through hole is provided. When the sliding connection is made to the through hole, the magnet in the electromagnetic tube 39 is disconnected from the electromagnetic property and disappears. Under the action of the restoring force of the auxiliary spring 310, the magnetic column 311 is pushed to slide toward the end away from the electromagnetic tube 39, and is inserted into the latch cavity 36 through the through hole on the rotating column 34, thereby fixing the relative position between the two link blocks 32, and preventing the link block 32 and the fitting surface of the repair part from shifting during the conveying process, thereby affecting the relative position change of the repair part.

[0050] Furthermore, after the delivery is completed, the magnet in the electromagnetic tube 39 is energized to generate magnetism, and is magnetically attracted to the magnetic column 311, so that the magnetic column 311 shrinks into the electromagnetic tube 39, and the connection between the magnetic column 311 and the latch cavity 36 is released, and then the air outlet valve 312 opens, and the air pressure in the air chamber formed by the rotating column 34 and the piston plate 37 is restored. Under the action of the spring at one end of the piston plate 37, the piston plate 37 is pulled to reset, waiting for the next round of operation;

[0051] By setting the special-shaped part fitting mechanism 3 and articulating multiple link blocks 32, the relative position fixing mechanism 2 can better adapt to various shapes of maintenance parts. According to the maintenance parts of different shapes, the link blocks 32 can fit the surface of the maintenance parts by rotating and offsetting, which greatly improves the versatility of the tooling, flexibly adjusts the angle, closely fits the surface of the maintenance parts, and realizes precise positioning. For maintenance parts with uneven surfaces, the rotation and offset of the hinge blocks can ensure that each contact point can fully fit with the maintenance parts, thereby increasing the contact area, improving the uniformity of the clamping force, and avoiding damage to the maintenance parts due to excessive local clamping force. At the same time, it can also better prevent the maintenance parts from shaking or shifting during transportation. Under the plug-in action of the magnetic column 311 and the pin cavity 36, fixing the hinge position can effectively prevent the relative position of the maintenance parts from changing during transportation. When encountering bumpy roads, sudden braking or sharp turns, the maintenance parts can also be firmly fixed in the clamping mechanism and will not be displaced due to the action of external forces, thereby avoiding damage or loss of accuracy caused by position changes.
