Description

Technical Field

[0001] The present invention belongs to the technical field of power engineering, and in particular, relates to an overhaul device for power engineering. Background Art

[0002] The power overhaul lifting basket is a device specifically used for high-altitude power engineering overhaul operations. It usually consists of a basket that can accommodate operators and tools, as well as related support and fixing devices. The traditional power overhaul lifting basket mainly relies on a crane for lifting and position adjustment, and realizes the fixation and movement of the basket through a single connection point. However, this traditional design has many limitations, such as insufficient safety and poor flexibility. Especially in a complex high-altitude operation environment, a single fixation method is difficult to provide sufficient safety protection.

[0003] The traditional power overhaul lifting basket only relies on a single-point fixation by a crane and has no additional anti-falling protection measures. Once the connection structure between the crane and the basket falls off, the basket will lose its only support point, and the basket may accidentally fall, directly threatening the lives of the operators. The falling of the basket may lead to serious casualties.

[0004] After retrieval, for example, the existing Chinese patent publication number: CN207645751U, a field power construction vehicle, includes an operating device, an axle, a construction vehicle main body, a maintenance window, movable tires, a motor, and a movable lighting lamp. The outside of the axle is fitted with the inside of the movable tires and is on the same axis. The maintenance window and the construction vehicle main body are of an integrated structure. The motor is electrically connected to the movable lighting lamp through a wire. The operating device includes a turntable connecting rod, a turntable, a leveling motor, a working basket, a guardrail, a folding arm, a folding arm luffing hydraulic cylinder, a second-stage arm, a basic arm, a main arm luffing hydraulic cylinder, and a rotating shaft. The turntable connecting rod is welded to the turntable.

[0005] The above-cited patent documents also have the same problem. The lifting basket only relies on a single-point fixation by a crane and has no additional anti-falling protection measures. Once the connection structure between the crane and the basket falls off, the basket will lose its only support point, and the basket may accidentally fall, directly threatening the lives of the operators. The falling of the basket may lead to serious casualties. Summary of the Invention

[0006] The purpose of the present invention is to provide an overhaul device for power engineering to solve the problems raised in the background art.

[0007] To achieve the above object, the present invention provides the following technical solution: An overhaul device for electric power engineering, comprising an electric power overhaul lifting basket and a support seat fixed to the bottom surface of the electric power overhaul lifting basket. One side of the bottom of the support seat is connected with a T-shaped connector through a detachable connection component. The T-shaped connector is fixed to a crane for electric power engineering overhaul, so that the crane can lift the electric power overhaul lifting basket. The detachable connection component can drive the electric power overhaul lifting basket to rotate and adjust to the required angle at the terminal of the crane. On the other side of the bottom of the support seat, an anti-falling mechanism is provided. The anti-falling mechanism comprises two arc-shaped clamping plates capable of relative movement. When the electric power overhaul lifting basket is lifted to the required height by the crane, the two arc-shaped clamping plates of the anti-falling mechanism move centripetally and clamp on the electric power pole in the electric power project to be overhauled, so that one side of the electric power overhaul lifting basket is connected and fixed by the crane, and the other side is clamped and fixed on the electric power pole. At the inner bottom of the electric power overhaul lifting basket, there is a basket inner bottom plate that can be driven by a lifting fine-tuning component.

[0008] Preferably in this solution, a connection ear sleeve is welded at the middle position of the outer wall of one side of the support seat. The T-shaped connector is in a horizontal shape, and an L-shaped connection plate in a reverse state is fixed to the outer wall of one side. A connection hole for connecting with the free end of the crane is opened at one end of the T-shaped connector.

[0009] Preferably in this solution, the detachable connection component comprises a connection shaft rotatably installed on the top surface of the detachable connection component and a connection hanging hole opened in the connection ear sleeve. The connection ear sleeve is hung on the connection shaft by fitting through the connection shaft.

[0010] Preferably in this solution, a plurality of key blocks are welded in an annular array on the outer wall of the circumferential side of the connection shaft, and a plurality of key grooves for the key blocks to fit, position and insert are opened in an annular array on the inner wall of the connection hanging hole.

[0011] Preferably in this solution, a first sealed bearing is embedded in the top surface of the L-shaped connection plate directly below the connection shaft. The bottom end of the connection shaft is integrally connected with a connecting shaft, and the connecting shaft is in interference fit connection with the inner ring of the first sealed bearing. The end of the L-shaped connection plate away from the T-shaped connector extends to the bottom surface of the support seat to support the support seat and is in sliding friction contact with the bottom surface of the support seat.

[0012] Preferably in this solution, two rib plates are symmetrically welded on the inner wall of the vertical corner of the L-shaped connection plate. Between the two rib plates and on the inner wall of the L-shaped connection plate, a first servo motor is fixedly installed. The output shaft of the first servo motor is fixedly connected with the connecting shaft.

[0013] Preferably, on the inner wall of the end of the L-shaped connecting platen away from the T-shaped connector, an anti-falling fixing block is welded, and on the outer wall of the anti-falling fixing block facing away from the T-shaped connector, a chute for installing the anti-falling mechanism is provided.

[0014] Preferably, the anti-falling mechanism includes a double-headed screw rotatably installed in the chute, external thread paths with opposite thread directions arranged on the outer walls of both ends of the double-headed screw, and moving clamping plates threadedly penetrating through both ends of the double-headed screw. Two arc-shaped clamping plates are integrally connected to the two moving clamping plates respectively.

[0015] Preferably, a second servo motor is fixed on the outer wall of one side of the anti-falling fixing block. The output shaft of the second servo motor penetrates into the chute and is fixed to one end of the double-headed screw. Both ends of the double-headed screw are connected to the inner wall of the chute through second sealing bearings.

[0016] Preferably, the lifting and fine-tuning assembly is arranged in the inner cavity of the support base. The lifting and fine-tuning assembly includes a lifting bottom plate installed on the bottom wall of the inner cavity of the support base, two groups of scissor lifting rods symmetrically hinged to the top surface of the lifting bottom plate, and a lifting plate hinged to the tops of the two groups of scissor lifting rods. An oil cylinder is hinged between the two groups of scissor lifting rods. The inner bottom plate of the hanging basket is fixed to the top surface of the lifting plate; symmetrically welded to the outer wall of the anti-falling fixing block directly below the middle of the double-headed screw are two ear plates. An active top rod is hinged between the two ear plates through a pin shaft. The end of the active top rod away from the ear plate is hinged to a lower support top plate. A pull ring is welded to the top surface of the active top rod near the lower support top plate. A pull rope is fixed to the pull ring. The end of the pull rope away from the pull ring winds around the periphery of the middle of the double-headed screw and is located between the two external thread paths.

[0017] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0018] For this overhaul device for electric power engineering, when the electric power overhaul hanging basket is lifted to the required height by a crane, the second servo motor drives the double-headed screw to rotate. The external thread paths drive the two moving clamping plates and the arc-shaped clamping plates to move towards the center to clamp the electric power pole. On the one hand, the electric power overhaul hanging basket is connected and fixed by the crane; on the other hand, the anti-falling mechanism clamps the electric power pole to provide double safety guarantees. Through the clamping action of the anti-falling mechanism, even if the crane fails or operates incorrectly, the electric power overhaul hanging basket will not accidentally fall, greatly improving the safety of high-altitude operations. The double-fixed design not only enhances safety but also provides more stable support, reducing the inconvenience of operation caused by shaking.

[0019] The rotation adjustment of the electric power maintenance lifting basket is realized by the cooperation of the connecting shaft and the key block with the key groove in the hanging hole. The reverse installation design of the L-shaped connecting platen and the T-shaped connecting head makes the installation of the device in different directions more convenient and fast. The electric power maintenance lifting basket can flexibly adjust the angle according to the actual situation on site, adapt to different working environments, without re-hoisting or moving the crane, saving time and labor costs. The design of the key block and the key groove makes the connection more stable and reliable, while simplifying the operation steps and improving work efficiency.

[0020] When the crane cannot accurately position, fine adjustment can be carried out through the lifting fine adjustment component to ensure that the electric power maintenance lifting basket reaches the required accurate position to meet different maintenance requirements. The design of the hydraulic damper and the top block reduces the shaking, improves the smoothness and comfort of the operation, and reduces the work fatigue of the operator.

Detailed implementation manners

[0032] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, some well-known technical features are not described to avoid confusion with the present invention.

[0033] This embodiment provides as Figures 1 to 8A maintenance device for electric power engineering shown in the figure includes an electric power maintenance lifting basket 1 and a support base 2 fixed to the bottom surface of the electric power maintenance lifting basket 1. One side of the bottom of the support base 2 is connected with a T-shaped connector 5 through a detachable connection assembly 7. The T-shaped connector 5 is fixed to a crane for electric power engineering maintenance, so that the crane can lift the electric power maintenance lifting basket 1. The detachable connection assembly 7 can drive the electric power maintenance lifting basket 1 to rotate and adjust to the required angle at the terminal of the crane. On the other side of the bottom of the support base 2, an anti-falling mechanism 8 is provided. The anti-falling mechanism 8 includes two arc-shaped clamping plates 23 that can move relative to each other. When the electric power maintenance lifting basket 1 is lifted to the required height by the crane, the two arc-shaped clamping plates 23 of the anti-falling mechanism 8 move centripetally and clamp on the electric power pole in the electric power engineering to be maintained, so that one side of the electric power maintenance lifting basket 1 is connected and fixed by the crane, and the other side is clamped and fixed on the electric power pole to achieve anti-falling. At the inner bottom of the electric power maintenance lifting basket 1, there is an inner bottom plate 25 of the lifting basket that can be driven by a lifting fine-tuning assembly. The design of the inner bottom plate 25 of the lifting basket and the lifting fine-tuning assembly enables the inner bottom plate 25 of the lifting basket to be lifted and fine-tuned by the lifting fine-tuning assembly when the crane is unable or inconvenient to finely adjust the height of the electric power maintenance lifting basket 1, so as to compensate for the part that the crane cannot adjust and meet the maintenance requirements at different positions in electric power engineering maintenance. The rotation adjustment of the electric power maintenance lifting basket 1 is realized by the cooperation of the connecting shaft 11 and the key block 12 with the key groove 10 in the hanging hole 9. The double-headed screw 35 is driven to rotate by the second servo motor 20, so that the two arc-shaped clamping plates 23 move centripetally to clamp the electric power pole, preventing accidental falling. The anti-falling mechanism 8 provides additional safety protection to ensure that no accidental falling occurs during high-altitude operations. The detachable connection assembly 7 enables the electric power maintenance lifting basket 1 to be flexibly adjusted in angle to adapt to different working environments. The lifting fine-tuning assembly can perform fine-tuning when the crane cannot accurately position, ensuring the accuracy of the maintenance position. On the outer wall of the support base 2 on the side facing away from the connecting ear sleeve 3, a detachable side plate 24 is installed by bolts. By removing the detachable side plate 24, the lifting fine-tuning assembly can be maintained.

[0034] In this embodiment, a connecting ear sleeve 3 is welded at the middle position of one outer wall of the support base 2. The T-shaped connector 5 is in a horizontal shape and an L-shaped connecting plate 4 in a reverse state is fixed to one outer wall. A connecting hole 6 for connecting with the free end of the crane is opened at one end of the T-shaped connector 5. The designs of the connecting ear sleeve 3 and the connecting hole 6 enable the T-shaped connector 5 to be stably fixed on the crane, and can be reversely installed through the L-shaped connecting plate 4. The designs of the connecting ear sleeve 3 and the connecting hole 6 increase the stability of the connection, avoiding the risk of loosening or falling off. The reverse installation design makes the installation of the device in different directions more convenient and fast.

[0035] In this embodiment, the detachable connection assembly 7 includes a connection shaft 11 rotatably mounted on the top surface of the detachable connection assembly 7 and a connection hanging hole 9 formed in the connection ear sleeve 3. The connection ear sleeve 3 is hung on the connection shaft 11 by fitting with the connection shaft 11. Through the cooperation of the connection shaft 11 and the connection hanging hole 9, the rotation adjustment of the electric power maintenance lifting basket 1 is realized. The design of the connection shaft 11 and the connection hanging hole 9 enables the electric power maintenance lifting basket 1 to flexibly adjust the angle to adapt to different working environments. The cooperative design of the key block 12 and the key slot 10 improves the reliability of the connection and prevents slipping.

[0036] In this embodiment, a plurality of key blocks 12 are welded in an annular array on the outer wall of the circumferential side of the connection shaft 11, and a plurality of key slots 10 for the key blocks 12 to be fitted and positioned and inserted are formed in an annular array on the inner wall of the connection hanging hole 9.

[0037] In this embodiment, a first sealing bearing 17 is embedded in the top surface of the L-shaped connection base plate 4 directly below the connection shaft 11. The bottom end of the connection shaft 11 is integrally connected with a connecting shaft 18. The connecting shaft 18 is in interference fit connection with the inner ring of the first sealing bearing 17. One end of the L-shaped connection base plate 4 away from the T-shaped connection head 5 extends to the bottom surface of the support seat 2 for supporting the support seat 2 and is in sliding friction contact with the bottom surface of the support seat 2. The first sealing bearing 17 provides rotational support, reduces friction and maintains stability. The first sealing bearing 17 reduces friction and extends the service life of the equipment. The design of the first sealing bearing 17 ensures the smooth rotation of the connection shaft 11 and improves the smoothness of operation.

[0038] In this embodiment, two rib plates 16 are symmetrically welded on the inner wall of the vertical corner of the L-shaped connection base plate 4. A first servo motor 19 is fixedly installed between the two rib plates 16 and on the inner wall of the L-shaped connection base plate 4. The output shaft of the first servo motor 19 is fixedly connected with the connecting shaft 18. The first servo motor 19 drives the connection shaft 11 to rotate through the connecting shaft 18 to realize angle adjustment. The first servo motor 19 realizes automatic angle adjustment, reduces the complexity and risk of manual operation, and the high-precision control ability of the servo motor ensures the accuracy of angle adjustment.

[0039] In this embodiment, an anti-falling fixing block 15 is welded on the inner wall of one end of the L-shaped connection base plate 4 away from the T-shaped connection head 5. A chute for installing the anti-falling mechanism 8 is formed on the outer wall of the side of the anti-falling fixing block 15 facing away from the T-shaped connection head 5. Rib blocks 21 are welded on both sides of the L-shaped connection base plate 4 and on the top surface of the anti-falling fixing block 15. The rib blocks 21 are used to support and stabilize the connection between the anti-falling fixing block 15 and the L-shaped connection base plate 4. The anti-falling fixing block 15 provides a stable installation platform, and the chute provides a moving space for the anti-falling mechanism 8. The anti-falling fixing block 15 increases the stability of the whole device and ensures that the anti-falling mechanism 8 can work reliably. The chute design enables the anti-falling mechanism 8 to move flexibly when needed to adapt to different working scenarios.

[0040] In this embodiment, the anti-falling mechanism 8 includes a double-headed screw 35 rotatably installed in the chute, external thread paths 36 provided on the outer walls of both ends of the double-headed screw 35 with opposite thread directions, and moving clamping plates 22 threadedly penetrating through both ends of the double-headed screw 35. Two arc-shaped clamping plates 23 are integrally connected to the two moving clamping plates 22 respectively. The double-headed screw 35 drives the two moving clamping plates 22 and the arc-shaped clamping plates 23 to move towards or away from the center, realizing the function of clamping or loosening the power pole. The design of the double-headed screw 35 and the external thread paths 36 ensures the uniform distribution of the clamping force, improves the reliability of the anti-falling protection, and realizes fast and reliable clamping and loosening operations through electric drive.

[0041] In this embodiment, a second servo motor 20 is fixed to the outer wall of one side of the anti-falling fixing block 15. The output shaft of the second servo motor 20 penetrates into the chute and is fixedly connected to one end of the double-headed screw 35. Both ends of the double-headed screw 35 are connected to the inner wall of the chute through second sealing bearings 37 at the smooth rod parts. Thus, when the second servo motor 20 runs forward, it drives the double-headed screw 35 to rotate clockwise in the chute. Under the design of the two external thread paths 36 with opposite thread directions, it drives the two moving clamping plates 22 to move towards the center, thereby driving the two arc-shaped clamping plates 23 to move towards the center and clamp on the power pole. When the second servo motor 20 runs in reverse and drives the double-headed screw 35 to rotate counterclockwise in the chute, the two moving clamping plates 22 are driven to move away from each other through the two external thread paths 36, thereby driving the two arc-shaped clamping plates 23 to move away from each other and open to release the clamping of the power pole. Therefore, after determining the position of the power maintenance lifting basket 1, the anti-falling setting can be carried out through the anti-falling mechanism 8. The second servo motor 20 drives the double-headed screw 35 to rotate, drives the moving clamping plates 22 and the arc-shaped clamping plates 23 to move towards or away from the center through the external thread paths 36. The second servo motor 20 realizes automatic clamping and loosening operations, reduces the risk of manual operation, and the high-precision control ability of the servo motor ensures the accuracy and consistency of the clamping and loosening actions.

[0042] In this embodiment, the lifting and fine-tuning assembly is arranged in the inner cavity of the support base 2. The lifting and fine-tuning assembly includes a lifting bottom plate 29 installed on the bottom wall of the inner cavity of the support base 2, two groups of scissor lifting rods 30 symmetrically hinged to the top surface of the lifting bottom plate 29, and a lifting plate 28 hinged to the tops of the two groups of scissor lifting rods 30. An oil cylinder 31 is hinged between the two groups of scissor lifting rods 30. The inner bottom plate 25 of the hanging basket is fixed to the top surface of the lifting plate 28. When the piston rod of the oil cylinder 31 extends, it drives the two groups of scissor lifting rods 30 to open, thereby driving the lifting plate 28 to rise, driving the inner bottom plate 25 of the hanging basket to finely rise in the electric power maintenance hanging basket 1. When the piston rod of the oil cylinder 31 contracts, it drives the two groups of scissor lifting rods 30 to compress and contract, so that the lifting plate 28 drives the inner bottom plate 25 of the hanging basket to finely descend in the electric power maintenance hanging basket 1, thereby realizing the fine adjustment of the lifting height. Removable maintenance windows 13 are installed on both outer walls of the support base 2 by bolts, and lifting rings 14 are installed on the outer wall of the support base 2 above the two removable maintenance windows 13. Four fixed sleeves 26 are welded in a rectangular distribution on the bottom wall of the inner cavity of the support base 2 around the lifting bottom plate 29, and four positioning and extending columns 27 are also welded in a rectangular distribution on the bottom surface of the inner bottom plate 25 of the hanging basket. Each positioning and extending column 27 is inserted into the corresponding fixed sleeve 26 in a fitting manner. Each fixed sleeve 26 has an inner cavity hole 32 inside, and a hydraulic damper 33 is longitudinally installed in the inner cavity hole 32. A top block 34 is welded to the top damping end of the hydraulic damper 33. The bottom end of the positioning and extending column 27 is inserted into the fixed sleeve 26 and presses on the top block 34. When the oil cylinder 31 drives the scissor lifting rods 30 to perform lifting operations, the inner bottom plate 25 of the hanging basket moves up and down accordingly, and the positioning and extending columns 27 slide up and down in the fixed sleeves 26. Through the design of the hydraulic damper 33 and the top block 34, the shaking and vibration generated during the lifting process can be effectively reduced. The design of the four fixed sleeves 26 and the four positioning and extending columns 27 provides four fixed guiding points, ensuring the vertical stability of the inner bottom plate 25 of the hanging basket during the lifting process. This design not only prevents the lateral offset of the inner bottom plate 25 of the hanging basket during the lifting process but also ensures its accurate positioning at different height positions.

[0043] In this embodiment, referring to Figure 8, on the middle and directly below the double-headed screw 35 and symmetrically welded to the outer wall of the anti-falling fixing block 15 are two ear plates 42. Between the two ear plates 42 is hinged an active ejector rod 40 through a pin shaft member 43. The end of the active ejector rod 40 away from the ear plate 42 is hinged to a lower support top plate 38. On the top surface of the end of the active ejector rod 40 close to the lower support top plate 38 is welded a pull ring 41. Fixed to the pull ring 41 is a pull rope 39. The end of the pull rope 39 away from the pull ring 41 winds around the circumference of the middle of the double-headed screw 35 and is located between two external thread paths 36. When the second servo motor 20 drives the double-headed screw 35 to rotate forward (clockwise), the double-headed screw 35 winds up the pull rope 39, causing the pull rope 39 to pull the pull ring 41, so that the end of the active ejector rod 40 close to the lower support top plate 38 is lifted, that is, the active ejector rod 40 rotates around the pin shaft member 43 as the center. When the double-headed screw 35 drives the two arc-shaped clamping plates 23 to move centripetally to clamp the power pole, the double-headed screw 35 pulls up the active ejector rod 40 through the pull rope 39, causing the lower support top plate 38 to be pulled up and abutted against the outer wall of the power pole synchronously. Thus, the two arc-shaped clamping plates 23 clamp the power pole centripetally at the upper part, while the lower support top plate 38 supports and abuts against the power pole at the lower part, and the fulcrum is set on the anti-falling fixing block 15, thereby forming a stable triangular support structure, further improving the stability of the power maintenance lifting basket 1. When the second servo motor 20 drives the double-headed screw 35 to rotate backward (counterclockwise), the double-headed screw 35 releases the pull rope 39. Under the self-weight of the lower support top plate 38 and the active ejector rod 40, the pull rope 39 is pulled down, causing the lower support top plate 38 and the two arc-shaped clamping plates 23 to release the clamping and support of the power pole synchronously, completing the release and erection.

[0044] Working principle:

[0045] For this maintenance device for power engineering, correctly install the T-shaped connector 5 at the free end of the crane and ensure a firm connection. Operate the crane to lift the power maintenance lifting basket 1 to the required height and adjust the angle according to the on-site situation. Use the connecting shaft 11 and key block 12 in the detachable connecting component 7 to cooperate with the key groove 10 in the connecting hanging hole 9 to ensure the stable suspension of the power maintenance lifting basket 1. After reaching the designated position, start the second servo motor 20 and make it run forward to drive the double-headed screw 35 to rotate clockwise.

[0046] The external thread paths 36 drive the two moving clamping plates 22 and the arc-shaped clamping plates 23 to move centripetally to clamp the power pole, completing the anti-falling fixation. If it is necessary to further adjust the height, start the oil cylinder 31, extend the piston rod, and push the two groups of scissor lifting rods 30 to expand, lifting the lifting plate 28 and the inner bottom plate 25 of the hanging basket. If it is necessary to lower the height, contract the piston rod of the oil cylinder 31 to make the scissor lifting rods 30 contract, driving the lifting plate 28 and the inner bottom plate 25 of the hanging basket to descend.

[0047] After completing the maintenance task, release the clamping state of the anti-falling mechanism 8, run the second servo motor 20 in the reverse direction to loosen the arc-shaped clamping plate 23. Finally, slowly lower the electric power maintenance lifting basket 1, and conduct inspection and maintenance of the equipment through the detachable maintenance window 13.

[0048] The electric power maintenance lifting basket 1 is connected to the T-shaped connector 5 through the detachable connection assembly 7 at the bottom of the support base 2, and the T-shaped connector 5 is fixed on the crane. When it is necessary to move or adjust the position of the electric power maintenance lifting basket 1, the crane operator can control the detachable connection assembly 7 to rotate the connecting shaft 11, thereby adjusting the angle of the electric power maintenance lifting basket 1.

[0049] An anti-falling mechanism 8 is provided on the other side of the support base 2. When the electric power maintenance lifting basket 1 is lifted by the crane to the required height, the two arc-shaped clamping plates 23 in the anti-falling mechanism 8 will move centripetally and clamp on the power pole. The anti-falling mechanism 8 is driven by the second servo motor 20 to rotate the double-headed screw rod 35. The outer walls at both ends of the double-headed screw rod 35 have external thread paths 36 in opposite directions, driving the two moving clamping plates 22 and the arc-shaped clamping plate 23 to move centripetally to clamp the power pole, providing additional safety protection.

[0050] The inner bottom plate 25 of the lifting basket is installed on the lifting fine-tuning assembly, which includes a lifting bottom plate 29, scissor lifting rods 30, an oil cylinder 31, and a lifting plate 28. When the crane cannot accurately adjust the height of the electric power maintenance lifting basket 1, the oil cylinder 31 can be used to drive the scissor lifting rods 30 to open or contract, and then drive the lifting plate 28 to rise or fall, realizing the fine-tuning lifting of the inner bottom plate 25 of the lifting basket to meet the maintenance requirements at different positions.

[0051] The positioning extension column 27 is inserted into the fixed sleeve 26, and a top block 34 is provided at the top to provide a buffering effect, reduce shaking and prevent lifting offset and dislocation.
