Description

Technical Field

[0001] The present invention relates to the technical field of deck jacking, and in particular to a mobile deck jacking device and a working method thereof. Background Art

[0002] During shipbuilding, repair, and modification, the installation, disassembly, and overall structural jacking of decks are crucial process steps. This is especially true for large ships and modular hull structures, where deck components are often large, heavy, and complex. Traditional fixed or track-mounted jacking equipment is not only limited in layout and inflexible, but also difficult to achieve efficient and safe operation in narrow working spaces and irregular terrain. Currently, some temporary jacking methods, such as the use of multiple hydraulic jacks for synchronous operation, suffer from technical bottlenecks such as large manual coordination errors, difficulty ensuring synchronization, and inconvenient mobility. These can easily lead to problems such as jacking angle deviations and uneven stress on the deck structure, thus affecting construction quality and operational safety. Therefore, there is an urgent need for a mobile jacking device with flexible deployment capabilities, strong synchronous control capabilities, and the ability to adapt to a variety of operating scenarios to improve the efficiency and safety of deck jacking operations.

[0003] With the development of intelligent manufacturing and refined construction technology, more and more ship manufacturers and engineering units have begun to explore solutions for jacking devices based on modularization and information control. However, most of the jacking systems currently on the market are dedicated or semi-fixed structures, which do not have good adaptability and are difficult to meet the jacking needs of decks of different sizes and structures under multiple working conditions. Especially in complex environments such as offshore operating platforms and large dock sites with uneven ground and small spaces, fixed equipment is cumbersome to operate and difficult to transfer. At the same time, traditional equipment requires high professionalism from operators during operation, which is prone to the risk of misoperation. Therefore, the development of a mobile deck jacking device that can achieve rapid mobile deployment, has high stability and adjustable jacking control functions can not only improve jacking efficiency and reduce the manpower burden, but also reduce construction costs and operational risks, providing more reliable and efficient technical support for the shipbuilding and maintenance industries.

[0004] In view of the above situation, in order to overcome the above technical problems, the present invention designs a movable deck jacking device and a working method thereof, which solves the above technical problems. Summary of the Invention

[0005] The technical purpose to be achieved by the present invention is to design a mobile deck jacking device and its working method to improve jacking efficiency, reduce manpower burden, and also reduce construction costs and operational risks, providing more reliable and efficient technical support for the shipbuilding and maintenance industries.

[0006] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0007] A mobile deck jacking device includes multiple structural units such as a chassis, a steering assembly, drive wheels, a battery box, a sliding track, a jacking mechanism, and a jacking plate. The overall structure is compact, the layout is reasonable, and it has good maneuverability and operational performance. The chassis is the supporting base of the device and is located at the bottom of the device. It is used to bear the weight of the entire jacking system and provide structural stability. Steering assemblies are installed at the four corners of the chassis. This assembly enables flexible movement of the device in multiple directions, facilitating layout and adjustment in confined or complex working environments. The drive wheels are respectively arranged on both sides of the chassis and provide forward or reverse power to the device by cooperating with the motor drive, thereby improving movement efficiency.

[0008] In order to ensure that the device has independent energy supply capabilities, the battery box is installed above the chassis, and supplies power to the controller, drive motor, jacking mechanism and other components in the entire system through wired or wireless means, reducing dependence on external power supplies. The sliding track is also provided above the chassis, serving as a structural channel for the movement or guidance of the jacking mechanism, providing an adjustable running path for the device and enhancing its adaptability. The jacking mechanism is installed in the center of the chassis and is the core component of the entire device for realizing deck jacking operations. The drive assembly and crossbar assembly are integrated inside it. The drive assembly drives the crossbar assembly to move smoothly on the sliding track through a motor or hydraulic device, thereby driving the jacking plate set above to lift upward, realizing a stable jacking operation of large components such as the deck. The entire system is easy to operate, and the jacking height is adjustable, which is suitable for deck operation requirements of different sizes and structures.

[0009] The device also includes a rotating assembly and a distance measuring sensor, which are used to enhance the flexibility and safety of the device during actual operation. The rotating assembly is installed in the peripheral area of ​​the jacking mechanism, and is mainly used to realize the rotation adjustment of the jacking mechanism and the jacking plate within a specific angle range, so that when the device is performing jacking operations on the deck or large components, it can make angle fine adjustments according to the actual position requirements to ensure jacking accuracy and force uniformity. The distance measuring sensors are installed at the front and rear ends of the chassis respectively, and have automatic measurement and real-time feedback functions. They can continuously monitor the distance between the device and surrounding obstacles, avoid collisions during movement or jacking, and improve the intelligence and safety level during operation. This structural design enables the device to not only have movement and jacking functions, but also have good adaptive adjustment and environmental perception capabilities, further improving the overall use effect.

[0010] The rotating assembly comprises three parts: a gear ring, a rotating motor, and a rotating gear, forming an efficient rotating transmission system for realizing the rotational adjustment function of the jacking mechanism. The gear ring is a circular structure tightly mounted on the outside of the jacking mechanism, and its inner wall is provided with evenly arranged tooth grooves for meshing with the rotating gear. The rotating motor is fixed next to the jacking mechanism and connected to the rotating gear via an output shaft. When the rotating motor is energized, it drives the rotating gear to rotate along the gear ring, thereby driving the entire jacking mechanism to rotate and adjust in the vertical direction. The rotating assembly has a simple structure and high transmission efficiency, and can achieve precise control of the jacking direction. It is particularly suitable for scenarios requiring multi-angle adjustment of the deck position. At the same time, the rotating motor can also be linked with the control system to achieve remote or automated angle adjustment, further improving operational convenience and operational flexibility.

[0011] The steering assembly includes a mounting frame, a mounting plate and a universal wheel, which are mainly used to realize multi-directional movement and flexible steering of the device in the horizontal plane. Specifically, the mounting frame is fixed at the four corners of the chassis to provide a stable support structure for the steering assembly; the mounting plate is installed under the mounting frame, serving as an intermediate component connecting the mounting frame and the universal wheel, and is used to bear weight and transmit motion force. The universal wheel is installed at the bottom of the mounting plate, and its structure has the characteristic of full-angle rotation, which can achieve 360-degree free rotation, so that the entire deck jacking device has multiple movement modes such as forward, backward, lateral movement and in-situ steering. This structural design greatly improves the maneuverability and operational flexibility of the device in limited space, and is especially suitable for ship interiors, narrow deck areas or complex working environments. It effectively avoids jamming or inability to turn during movement, and further improves overall use efficiency and on-site adaptability.

[0012] The jacking mechanism includes a jacking base plate, a limit frame, a drive assembly, a crossbar assembly and a support assembly, which constitute the core functional structure of the entire device to realize the deck jacking action. Among them, the jacking base plate is installed on the chassis and serves as the basic bearing platform of the jacking mechanism, bearing the weight and working pressure of the entire jacking part; the limit frame is fixed above the jacking base plate, which is used to limit and guide the range of motion of the crossbar assembly to ensure stability and safety during the jacking process. The drive assembly is also installed on the jacking base plate and is responsible for providing power input to the crossbar assembly, usually controlled by electric or hydraulic means. The crossbar assembly is arranged inside the limit frame and serves as an intermediate structure for bearing and transmission. It can be raised and lowered under drive; the support assembly is installed in the middle part of the crossbar assembly to connect and support the jacking plate to realize the transmission of the jacking load. The entire jacking mechanism has a compact structure and clear functions, and can realize smooth and controllable jacking action to meet the precise lifting requirements of large components such as decks.

[0013] The crossbar assemblies are arranged in a paired structure, that is, two groups of crossbar assemblies are symmetrically arranged inside each limit frame, respectively located on the left and right sides of the limit frame. This symmetrical arrangement helps to maintain force balance during the jacking process and avoid the occurrence of structural overload or tilt. Each group of crossbar assemblies can achieve synchronous expansion and contraction through hinged or sliding connections, thereby ensuring the coordination and stability of the jacking action. The support assembly is installed in a cross structure between the two groups of crossbar assemblies, and the overall support stiffness and load-bearing capacity are enhanced by cross-connection. At the same time, the height position can be automatically adjusted according to the movement of the crossbar assembly. This cross-support arrangement not only improves the stability and deformation resistance of the jacking platform, but also makes the jacking action more stable and smooth. It is especially suitable for jacking heavy-loaded decks or special-shaped components and other operating scenarios that require high support accuracy, thereby improving the actual use effect and safety performance of the entire device.

[0014] The drive assembly includes a drive motor, a drive rod, a drive block and a fixed block, which constitute a complete power transmission system for realizing the lifting and lowering action of the jacking mechanism. The drive motor is installed above the jacking base plate and provides the main power source for the entire jacking structure. The motor output shaft is connected to the drive rod and can convert the rotational motion into a linear thrust. The drive rod is arranged on the side of the drive motor and is arranged horizontally or vertically. It is connected to the drive block as a transmission medium and drives it to move along the set trajectory. The drive block is tightly wrapped around the periphery of the drive rod. A guide structure is provided inside it, which can slide stably under the action of the drive rod, thereby driving the cross bar assembly or support component to rise and fall synchronously to realize the control of the jacking plate. The fixed block is installed on the jacking base plate and is used to provide positioning and limiting support for the drive rod and drive block to prevent deviation or shaking, and ensure the safety and accuracy of the driving process. The drive assembly has a reasonable structure, rapid response, good load-bearing capacity and control performance, and can meet the stable jacking requirements under different load conditions.

[0015] The crossbar assembly includes a limit block, a bearing ring and a movable crossbar, which constitute the key part of the jacking mechanism for transmitting power and supporting the structure. The limit block is installed inside the limit frame and serves as the installation base for the movable crossbar. Its cross-sectional shape is designed to be rectangular, which is conducive to close fit with the inner wall of the limit frame, thereby improving the stability of the structure. The height value of the limit block is consistent with the internal height value of the limit frame, so that it can be firmly positioned in the frame to prevent shaking or deviation during movement. The bearing ring is embedded in the middle of the limit block, which plays a supporting and guiding role, and reduces the friction resistance when the crossbar moves through the rolling structure. The movable crossbar is installed in the center hole of the bearing ring and can perform smooth telescopic movement under the drive of the drive assembly. The overall structural design is compact, the installation is stable, and the operation is smooth, which ensures that the crossbar assembly has good mechanical properties and guiding effects during the jacking process, thereby improving the operating accuracy and service life of the entire device.

[0016] The support assembly includes a support rod and mounting holes, which are important parts of the load-bearing and connection in the jacking mechanism, and play a key role in supporting the jacking plate and transferring the load. The support rod is installed above the crossbar assembly and arranged horizontally. It can effectively withstand the vertical pressure from the jacking plate and ensure the structural stability and safety during the jacking process. There are multiple mounting holes on the support rod, specifically three mounting holes, which are located at both ends and the middle of the support rod. This arrangement not only facilitates a firm connection with the jacking plate or other components, but also evenly distributes stress and reduces the potential risks caused by local force concentration. The reasonable distribution of mounting holes improves the applicability and flexibility of the support assembly, and is convenient for adjustment and installation according to different operating requirements, ensuring that the entire jacking device can maintain good load-bearing capacity and stable operation under various complex working conditions.

[0017] A method for operating a mobile deck jacking device is provided, and the method is used in conjunction with the mobile deck jacking device described above. The steps of the method are as follows:

[0018] S1: The operator operates the mobile deck jacking device. The steering assembly is responsible for direction control, the drive wheels are responsible for carrying the load and moving forward, the battery box supplies power to the entire mobile deck jacking device, and the ranging sensor is used to maintain a safe distance between the mobile deck jacking device and other machinery, thereby helping the mobile deck jacking device move to the designated position.

[0019] S2: The lifting device slides on the sliding track and is adjusted to a suitable position, and the rotating assembly is started when necessary to make the lifting mechanism at a suitable lifting angle;

[0020] S3: The driving motor drives the driving rod to rotate, and the driving rod rotates and moves forward in the fixed block, thereby driving the driving block to move horizontally. Since the limit block can only move within the limit frame and under the limiting effect of the support rod, the crossbar components on the same horizontal plane are closer;

[0021] S4: Shorten the distance between the two crossbar assemblies, and under the constraints of the remaining components, the upper crossbar assembly rises.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) The present invention has the significant advantages of compact structure and maneuverability. Through the rational design of key components such as the chassis, steering assembly and drive wheels, the device can move freely in multiple directions in a small space, greatly improving the flexibility and adaptability of the work site. In particular, the rotating assembly and ranging sensor equipped with the device not only realize the precise angle adjustment of the jacking mechanism, but also can perceive the surrounding environment in real time, ensuring the safety and efficiency of the operation process. In addition, the integration of the battery box provides the device with stable independent power support, getting rid of the dependence on external power supply, making it more suitable for changeable and complex construction sites. The overall design takes into account both operational convenience and structural stability, significantly improving the efficiency and safety level of jacking operations.

[0024] (2) The jacking mechanism of the present invention adopts a multi-component collaborative working mode to ensure the smooth and reliable jacking action. The crossbar components arranged in pairs are combined with the cross-mounted support components to enhance the overall load-bearing capacity and structural stability, and effectively prevent the tilting and uneven force problems that may occur during the jacking process. The drive component adopts electric drive, combined with the precise limit block and bearing ring design, to achieve precise control of the jacking height and angle, and meet the jacking requirements of different deck sizes and weights. At the same time, the device has a simple structure and is easy to maintain. It can be widely used in shipbuilding, maintenance and other occasions that require the jacking of large components, improving the automation and intelligence level of the operation, and greatly promoting the technological progress of related industries.

DETAILED DESCRIPTION

[0035] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] like Figure 1-7 As shown, a mobile deck jacking device includes multiple structural units such as a chassis 1, a steering assembly 2, a drive wheel 3, a battery box 4, a sliding track 5, a jacking mechanism 6 and a jacking plate 7. The overall structure is compact and the layout is reasonable, with good maneuverability and operational performance. The chassis 1 is the supporting base of the device and is arranged at the bottom of the device to bear the weight of the entire jacking system and provide structural stability; the steering assembly 2 is installed at the four corners of the chassis 1, which can realize flexible movement of the device in multiple directions, facilitating arrangement and adjustment in a small or complex working environment. The drive wheels 3 are respectively arranged on both sides of the chassis 1, and provide forward or backward power to the device by cooperating with the motor drive, thereby improving the movement efficiency.

[0037] In order to ensure that the device has independent energy supply capabilities, the battery box 4 is installed above the chassis 1, and supplies power to the controller, drive motor 631, jacking mechanism 6 and other components in the entire system through wired or wireless means, reducing dependence on external power supplies. The sliding track 5 is also set above the chassis 1, serving as a structural channel for the movement or guidance of the jacking mechanism 6, providing an adjustable running path for the device and enhancing its adaptability. The jacking mechanism 6 is installed in the center of the chassis 1 and is the core component of the entire device for realizing deck jacking operations. The drive assembly 63 and the crossbar assembly 64 are integrated inside it. The drive assembly 63 drives the crossbar assembly 64 to move smoothly on the sliding track 5 through a motor or hydraulic device, thereby driving the jacking plate 7 set above to lift upward, realizing a stable jacking operation of large components such as decks. The entire system is easy to operate, and the jacking height is adjustable, which is suitable for deck operation requirements of different sizes and structures.

[0038] like Figure 6-7 As shown, the device also includes a rotating assembly 8 and a distance sensor 9, which are used to enhance the flexibility and safety of the device during actual operation. The rotating assembly 8 is installed in the peripheral area of ​​the jacking mechanism 6, and is mainly used to realize the rotation adjustment of the jacking mechanism 6 and the jacking plate 7 within a specific angle range, so that when the device performs jacking operations on the deck or large components, it can fine-tune the angle according to the actual position requirements to ensure the jacking accuracy and force uniformity. The distance sensor 9 is installed at the front and rear ends of the chassis 1 respectively, and has automatic measurement and real-time feedback functions. It can continuously monitor the distance between the device and surrounding obstacles, avoid collisions during movement or jacking, and improve the intelligence and safety level during operation. This structural design enables the device to not only have movement and jacking functions, but also have good adaptive adjustment and environmental perception capabilities, further improving the overall use effect.

[0039] like Figure 7 As shown, the rotating assembly 8 comprises a gear ring 81, a rotating motor 82, and a rotating gear 83, forming a highly efficient rotary transmission system for achieving the rotational adjustment function of the jacking mechanism 6. The gear ring 81 is a circular structure tightly mounted on the outside of the jacking mechanism 6. Its inner wall is provided with evenly spaced teeth and grooves for meshing with the rotating gear 83. The rotating motor 82 is fixed adjacent to the jacking mechanism 6 and connected to the rotating gear 83 via an output shaft. When energized, the rotating motor 82 drives the rotating gear 83 to rotate along the gear ring 81, thereby rotating the entire jacking mechanism 6 in the vertical direction. This rotating assembly 8 features a simple structure, high transmission efficiency, and precise control of the jacking direction, making it particularly suitable for scenarios requiring multi-angle deck position adjustment. Furthermore, the rotating motor 82 can be linked to a control system to enable remote or automated angle adjustment, further enhancing operational convenience and flexibility.

[0040] like Figure 5 As shown, the steering assembly 2 includes a mounting frame 21, a mounting plate 22 and a universal wheel 23, which are mainly used to realize multi-directional movement and flexible steering of the device in the horizontal plane. Specifically, the mounting frame 21 is fixedly set at the four corners of the chassis 1 to provide a stable support structure for the steering assembly 2; the mounting plate 22 is installed below the mounting frame 21, serving as an intermediate component connecting the mounting frame 21 and the universal wheel 23, for bearing weight and transmitting motion force. The universal wheel 23 is installed at the bottom of the mounting plate 22. Its structure has the characteristic of full-angle rotation and can achieve 360-degree free rotation, so that the entire deck jacking device has multiple movement modes such as forward, backward, lateral movement and in-situ steering. This structural design greatly improves the maneuverability and operational flexibility of the device in a limited space, and is particularly suitable for ship interiors, narrow deck areas or complex working environments. It effectively avoids jamming or inability to turn during movement, and further improves overall use efficiency and on-site adaptability.

[0041] like Figure 2 As shown, the jacking mechanism 6 includes a jacking base plate 61, a limit frame 62, a drive assembly 63, a crossbar assembly 64 and a support assembly 65, which constitute the core functional structure of the entire device to realize the deck jacking action. Among them, the jacking base plate 61 is installed on the chassis 1, serving as the basic bearing platform of the jacking mechanism 6, bearing the weight and working pressure of the entire jacking part; the limit frame 62 is fixed above the jacking base plate 61, and is used to limit and guide the range of motion of the crossbar assembly 64 to ensure stability and safety during the jacking process. The drive assembly 63 is also installed on the jacking base plate 61, responsible for providing power input to the crossbar assembly 64, and is usually controlled by electric or hydraulic means. The crossbar assembly 64 is arranged inside the limit frame 62, serving as an intermediate structure for bearing and transmission, and can be raised and lowered under drive; the support assembly 65 is installed in the middle part of the crossbar assembly 64, and is used to connect and support the jacking plate 7 to realize the transmission of the jacking load. The entire jacking mechanism 6 has a compact structure and clear functions, and can achieve a smooth and controllable jacking action to meet the precise lifting requirements of large components such as decks.

[0042] The crossbar assemblies 64 are arranged in pairs, that is, two groups of crossbar assemblies 64 are symmetrically arranged inside each limit frame 62, respectively located on the left and right sides of the limit frame 62. This symmetrical arrangement helps to maintain force balance during the jacking process and avoid the occurrence of structural overload or tilt. Each group of crossbar assemblies 64 can achieve synchronous expansion and contraction through hinged or sliding connections, thereby ensuring the coordination and stability of the jacking action. The support assembly 65 is installed in a cross structure between the two groups of crossbar assemblies 64, and the overall support stiffness and load-bearing capacity are enhanced by cross-connection. At the same time, the height position can be automatically adjusted according to the movement of the crossbar assembly 64. This cross-support arrangement not only improves the stability and anti-deformation ability of the jacking platform, but also makes the jacking action more stable and smooth. It is particularly suitable for jacking heavy-loaded decks or special-shaped components and other work scenarios that require high support accuracy, thereby improving the actual use effect and safety performance of the entire device.

[0043] like Figure 3 As shown, the drive assembly 63 includes a drive motor 631, a drive rod 632, a drive block 633, and a fixed block 634, forming a complete power transmission system for achieving the lifting and lowering movement of the jacking mechanism 6. The drive motor 631 is installed above the jacking base plate 61 and provides the main power source for the entire jacking structure. The motor output shaft is connected to the drive rod 632, which can convert rotational motion into linear propulsion. The drive rod 632 is arranged on the side of the drive motor 631, either horizontally or vertically, and serves as a transmission medium to connect the drive block 633 and drive it along a set trajectory. The drive block 633 tightly wraps around the periphery of the drive rod 632 and is equipped with a guide structure inside. It can slide stably under the action of the drive rod 632, thereby driving the crossbar assembly 64 or the support component to rise and fall synchronously, thereby achieving control of the jacking plate 7. The fixed block 634 is installed on the jacking base plate 61 to provide positioning and limiting support for the drive rod 632 and the drive block 633, preventing deviation or shaking, and ensuring the safety and accuracy of the driving process. The drive assembly 63 has a reasonable structure, quick response, good load-bearing capacity and control performance, and can meet the stable jacking requirements under different load conditions.

[0044] like Figure 4As shown, the crossbar assembly 64 includes a limit block 641, a bearing ring 642, and a movable crossbar 643, forming a key component of the jacking mechanism 6 for transmitting power and supporting the structure. The limit block 641 is installed inside the limit frame 62 and serves as the mounting base for the movable crossbar 643. Its rectangular cross-section facilitates a close fit with the inner wall of the limit frame 62, thereby improving structural stability. The height of the limit block 641 is consistent with the internal height of the limit frame 62, allowing it to be firmly positioned within the frame and prevent shaking or deviation during movement. The bearing ring 642 is embedded in the middle of the limit block 641, providing support and guidance, and reducing frictional resistance during crossbar movement through a rolling structure. The movable crossbar 643 is installed in the center hole of the bearing ring 642 and can perform smooth telescopic movement driven by the drive assembly 63. The overall structural design is compact, the installation is stable, and the operation is smooth, ensuring that the crossbar assembly 64 has good mechanical properties and guidance effects during the jacking process, thereby improving the operating accuracy and service life of the entire device.

[0045] like Figure 3 As shown, the support assembly 65 includes a support rod 651 and a mounting hole 652. As an important part of the load-bearing and connection in the jacking mechanism 6, it plays a key role in supporting the jacking plate 7 and transferring the load. The support rod 651 is installed above the crossbar assembly 64 and arranged horizontally. It can effectively withstand the vertical pressure from the jacking plate 7 and ensure the structural stability and safety during the jacking process. A plurality of mounting holes 652 are provided on the support rod 651, specifically three mounting holes 652, which are respectively located at both ends and the middle position of the support rod 651. This arrangement not only facilitates a firm connection with the jacking plate 7 or other components, but also evenly distributes stress and reduces the potential risks caused by local force concentration. The reasonable distribution of the mounting holes 652 improves the applicability and flexibility of the support assembly 65, and is convenient for adjustment and installation according to different operating requirements, ensuring that the entire jacking device can maintain good load-bearing capacity and stable operation under various complex working conditions.

[0046] A method for operating a mobile deck jacking device is provided, and the method is used in conjunction with the mobile deck jacking device described above. The steps of the method are as follows:

[0047] S1: A worker operates the mobile deck jacking device. The steering assembly 2 is responsible for direction control, the drive wheel 3 is responsible for carrying the load and moving forward, the battery box 4 supplies power to the entire mobile deck jacking device, and the distance sensor 9 is used to maintain a safe distance between the mobile deck jacking device and other machinery, thereby helping the mobile deck jacking device move to the designated position.

[0048] S2: The lifting device slides on the sliding track 5 to a suitable position, and when necessary, the rotating assembly 8 is started to make the lifting mechanism 6 at a suitable lifting angle;

[0049] S3: The driving motor 631 drives the driving rod 632 to rotate, and the driving rod 632 rotates and moves forward in the fixing block 634, thereby driving the driving block 633 to move laterally. Since the limiting block 641 can only move in the limiting frame 62, and under the limiting effect of the support rod 651, the crossbar assemblies 64 on the same horizontal plane are closer to each other;

[0050] S4: The distance between the two crossbar assemblies 64 is shortened, and under the restriction of the remaining components, the upper crossbar assembly 64 rises.

[0051] During the operation of the present invention, the staff first operates the mobile deck jacking device, realizes precise direction control through the steering assembly 2, and the driving wheel 3 takes on the load-bearing forward task of the device to ensure that the equipment can move smoothly. The battery box 4 provides stable power support for the entire device to ensure the efficient operation of each system. The distance measuring sensors 9 installed at the front and rear ends of the chassis 1 monitor the safe distance between the device and the surrounding mechanical equipment in real time to prevent collisions and ensure safety and smoothness during movement. With the help of these functions, the mobile deck jacking device can be accurately positioned to the predetermined working position. After positioning is completed, the jacking device slides along the path provided with the sliding track 5 and is adjusted to a suitable working position. The rotating assembly 8 is started as needed, and the angle of the jacking mechanism 6 is adjusted to make it in the best jacking posture to meet the lifting requirements of different deck components.

[0052] Subsequently, the drive motor 631 starts working, driving the drive rod 632 to rotate. The drive rod 632 moves forward under the guidance of the fixed block 634, thereby pushing the drive block 633 to slide in the lateral direction. Since the limit block 641 is restricted to move within the limit frame 62 and is restricted by the support rod 651, the spacing between the cross bar assemblies 64 on the same horizontal plane in the device gradually shortens. This structural design ensures the synchronous movement and uniform force of the cross bar assemblies 64. Under the constraints and cooperation of other components, the cross bar assembly 64 above the device rises accordingly, achieving stable jacking of the deck. The entire process is coordinated and orderly, ensuring that the jacking action is smooth and precise, effectively improving work efficiency and safety, and adapting to various complex working environments.
