Description

Technical Field

[0001] This utility model relates to the field of shipbuilding and repair technology, specifically to an automated hoisting device for shipbuilding and repair. Background Technology

[0002] In the shipbuilding and repair industry, the transfer and installation of workpieces are inseparable from hoisting operations. As a key auxiliary tool, the performance of hoisting equipment directly affects the efficiency and quality of the operation. With the continuous development of shipbuilding and repair technology, increasingly higher requirements are being placed on the stability, accuracy, and operational flexibility of hoisting operations to adapt to the diverse operational needs under complex working conditions.

[0003] However, existing hoisting equipment used in shipbuilding and repair still has some shortcomings in practical applications. Some equipment is prone to swaying during hoisting, affecting the accuracy of the operation and making it difficult to fully meet the high standards of operation required in the shipbuilding and repair field.

[0004] To address these issues, an automated hoisting device for ship repair and construction is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an automated hoisting device for ship repair and construction, which has the advantage of improving the stability of hoisting operations and solves the problem that existing hoisting equipment used in ship repair and construction is prone to shaking during hoisting, resulting in insufficient accuracy of hoisting operations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated hoisting device for ship repair and construction, comprising a frame and a hoisting mechanism mounted on the frame. The frame includes a vertical frame on which a crossbeam is mounted. The hoisting mechanism includes a first traction component, a second traction component, a limiting component, a winch, and a hook. The first traction component and the second traction component are respectively mounted on the crossbeam and can both move horizontally along the extension direction of the crossbeam. The limiting component is installed via the first and second traction components to limit its own horizontal displacement. The winch is mounted on the second traction component to provide hoisting power. The hook is connected to the winch via a lifting attachment connector to hook and receive the workpiece to be hoisted.

[0007] Preferably, the bottom of the support frame is equipped with casters, which are used to move the frame flexibly, and the casters are equipped with brake devices.

[0008] In the design, the casters installed at the bottom of the frame and the brake devices on the casters enable the frame to move flexibly and be fixed in one place. It has the characteristics of balancing the convenience of moving the device and the stability of its position during operation, and can meet the needs of adjusting and fixing the position of the device in different working scenarios.

[0009] Preferably, the crossbeam includes a lower crossbeam and an upper crossbeam. The lower crossbeam is installed on the upright, and the upper crossbeam is installed on the lower crossbeam. The two work together to provide installation support for the lifting mechanism.

[0010] The design incorporates a beam structure consisting of a lower beam and an upper beam. The lower beam is mounted on the support frame, and the upper beam is mounted on the lower beam. This assembly method provides layered support for the lifting mechanism, offering a stable installation foundation and adapting to the installation needs of multiple components, thus ensuring the overall stability of the lifting mechanism's operation.

[0011] Preferably, the first traction component is slidably mounted on a preset guide rail of the upper crossbeam, and the second traction component is slidably mounted on a guide rail of the same specification of the lower crossbeam. The surface of the crossbeam guide rail is reinforced to reduce frictional resistance.

[0012] In the design, the first traction component is slidably installed on the pre-set guide rail of the upper crossbeam, and the second traction component is slidably installed on the same specification guide rail of the lower crossbeam. The design of the crossbeam guide rail surface being reinforced enables the first traction component and the second traction component to move smoothly horizontally along the crossbeam. It has the characteristics of reducing the displacement friction resistance of the traction component, ensuring the synchronization and stability of the displacement of the two traction components, and improving the horizontal adjustment efficiency of the hoisting operation.

[0013] Preferably, a first limiting frame is installed on the first traction component, and a second limiting frame is installed on the second traction component. The limiting components are installed on the first limiting frame and the second limiting frame, and are limited by the first traction component and the second traction component.

[0014] In the design, the first limiting frame installed on the first traction component, the second limiting frame installed on the second traction component, and the structure in which the limiting component is installed on the two limiting frames and limited by the two traction components, realize the precise positioning and installation of the limiting component. It has the characteristics of ensuring the stability of the limiting component installation and avoiding the displacement deviation of the limiting component, thus ensuring that the limiting component can effectively perform its limiting function.

[0015] Preferably, the limiting assembly includes two guide rods, with a first limiting frame and a second limiting frame respectively passing through the top of the two guide rods, and a limiting rod fixedly installed at the end. The guide rods are used to guide the movement of the hook, and a connecting ring is installed at the bottom of the guide rods, with a rotating shaft installed on the connecting ring.

[0016] In the design, the top of the two guide rods of the limiting component are respectively fitted with the first limiting frame and the second limiting frame, and the end of the limiting rod is fixed. The bottom of the guide rod is fitted with a connecting ring and the connecting ring is fitted with a rotating shaft. This structure realizes the directional guidance of the hook movement, which has the characteristics of accurately limiting the hook movement trajectory and avoiding large swings of the hook, while ensuring the integrity of the limiting component's own structure and the reliability of its function.

[0017] Preferably, a pulley is installed inside the lifting device connector via a rotating shaft, and a steel wire rope is threaded through the pulley. Both ends of the steel wire rope away from the pulley are connected to a winch.

[0018] In the design, the pulleys installed through the pivot in the lifting device connector, and the wire ropes threaded on the pulleys and connected to the winches at both ends, realize the smooth transmission of power from the winches to the hook. This reduces power transmission loss, ensures the smoothness of the hook lifting process, and improves the safety and accuracy of lifting operations.

[0019] Preferably, the winch is equipped with a control switch, which is used to control the operating status of the winch.

[0020] In the design, the control switch installed on the winch enables direct control of the winch's operating status. It allows operators to flexibly control the start-stop and operating parameters of the winch according to the work progress, improving the ease of operation and controllability of hoisting operations and adapting to the hoisting needs of different workpieces.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This utility model sets up a frame in which the crossbeam installed on the upright of the frame provides a stable mounting foundation for the first traction component and the second traction component. The first traction component and the second traction component are respectively installed on the crossbeam and can both be horizontally displaced along the extension direction of the crossbeam. This can ensure that the lifting mechanism maintains a stable movement state during the horizontal adjustment process and avoid swaying caused by unstable component installation.

[0023] The limiting component is installed by the first traction component and the second traction component, which can strictly limit its own horizontal displacement stroke and prevent the limiting component from shifting and indirectly causing the hook to sway.

[0024] The winch is installed on the second traction assembly to provide a continuous and stable power output for the lifting operation. The hook is connected to the winch through the lifting tool connector, which can ensure the stability of the power transmission process and reduce the impact of power fluctuations on the hook. Ultimately, this improves the stability of the lifting operation and solves the problem that existing shipbuilding and repair lifting equipment is prone to shaking during the lifting process, resulting in insufficient accuracy of the lifting operation.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is an automated hoisting device for ship repair and construction, comprising a frame 1 and a hoisting mechanism 2 fastened to the frame 1 by bolts.

[0033] The frame 1 includes two symmetrically arranged uprights 11. The uprights 11 are made of Q235 rectangular steel pipes. At the four corners of the bottom of the uprights 11, casters 111 are fixedly installed with M10 bolts. The casters 111 are polyurethane wheels with brake pads. The brake pads are controlled by a foot pedal linkage. The casters 111 are used to enable the frame 1 to move flexibly on the floor of the ship repair workshop, and stepping on the brake pads can fix the frame 1 at a fixed point.

[0034] A lower crossbeam 12 is welded to the top of the upright 11. The lower crossbeam 12 is also a Q235 rectangular steel pipe, and its length is adapted to the distance between the two uprights 11. The upper crossbeam 13 is fixed to the top of both ends of the lower crossbeam 12 by M16 high-strength bolts. The upper crossbeam 13 is a rectangular steel pipe with the same specifications as the lower crossbeam 12. The upper crossbeam 13 and the lower crossbeam 12 form a double-layer support structure to provide stable installation support for different components of the lifting mechanism 2.

[0035] The lifting mechanism 2 includes a first traction component 21 and a second traction component 23. Both are non-powered small wheels with guide rails, and the specifications of the small wheels, guide rails, and other parameters are completely identical, which can ensure a synchronous and stable working state during horizontal displacement. The slider of the first traction component 21 is made of cast iron, and the small wheel is inlaid with a polytetrafluoroethylene wear-resistant bushing. It is slidably installed on the guide rail preset on the top of the upper crossbeam 13. The guide rail is made of No. 45 steel and the surface is chrome-plated to reduce frictional resistance and ensure smooth slider displacement.

[0036] The slider structure of the second traction component 23 is the same as that of the first traction component 21. It is correspondingly slidably installed on the same specification guide rail on the top of the lower crossbeam 12. The horizontal displacement of both components depends on the external traction force, and the displacement stroke of both components along the extension direction of their respective crossbeams is adapted to the transfer distance of commonly used workpieces in ship repair and construction.

[0037] The first traction assembly 21 is fixedly installed with a first limiting frame 211 by M12 high-strength bolts, and the second traction assembly 23 is fixedly installed with a second limiting frame 231 by bolts of the same specification. Both the first limiting frame 211 and the second limiting frame 231 are provided with guide holes that are compatible with the guide rod 222.

[0038] The first limiting frame 211 and the second limiting frame 231 jointly support and install the limiting component 22. The limiting component 22 includes two guide rods 222 of the same specification. The guide rods 222 are made of No. 45 round steel. The top of the guide rods 222 are respectively provided with guide holes of the first limiting frame 211 and the second limiting frame 231. The top of the guide rods 222 is fixedly installed with the limiting rods 221 by welding. This can limit the stroke of the longitudinal displacement of the first traction component 21 and the second traction component 23, and prevent the limiting component 22 from falling.

[0039] Meanwhile, rubber buffer pads are attached to the inner walls of the guide holes of the first limiting frame 211 and the second limiting frame 231. When the first traction component 21 and the second traction component 23 are moved to the target position, the interference fit between the guide rod 222 and the guide hole can provide an auxiliary positioning effect to prevent the components from shifting slightly during the hoisting operation.

[0040] A connecting ring 223 is fixedly installed at the bottom of the guide rod 222 by welding. The connecting ring 223 is a stainless steel ring, and a rotating shaft 224 is welded to its inner wall. The rotating shaft 224 is a stainless steel pin.

[0041] A winch mounting plate is fixedly installed on one side of the second traction assembly 23 by bolts. A winch 24 is fixedly installed on the mounting plate by M8 bolts. The winch 24 is a small electric winch with a rated pulling force that is compatible with the weight of commonly used workpieces in shipbuilding and repair, and is used to provide stable lifting power for hoisting operations.

[0042] Below the drum of the winch 24, there is a lifting device connector 25. A pulley is installed in the lifting device connector 25 through a rotating shaft 224. The pulley is made of cast steel and its groove is compatible with the wire rope. The wire rope is threaded on the pulley. Both ends of the wire rope away from the pulley are fixed to the drum of the winch 24 by rope clamps. One end is fixed to the left side of the drum and the other end is fixed to the right side of the drum, forming a double rope traction structure, which can prevent the lifting device connector 25 from tilting during the lifting process.

[0043] A control switch 27 is installed on the winch 24 via a signal source line. The control switch 27 is a waterproof push-button switch with an emergency stop button. It is electrically connected to the drive motor of the winch 24 via a wire and is used to control the start, stop and forward / reverse rotation of the winch 24.

[0044] The bottom of the lifting connector 25 is fixedly installed with a hook 26 by welding. The hook 26 is a forged alloy steel hook, and a spring-type safety pin can be set at its opening to prevent the workpiece from falling off during the lifting process. The rated lifting capacity of the hook 26 matches the rated pulling force of the winch 24 and is used to hook the workpiece that needs to be lifted during the ship repair and construction process.

[0045] During hoisting operations, the horizontal displacement of the lifting device connector 25 is constrained by the guide rod 222 of the limiting component 22. Combined with the synchronous horizontal displacement of the first traction component 21 and the second traction component 23, large-angle horizontal swaying of the hook 26 can be avoided. At the same time, the double-layer beam support structure and the double-rope traction lifting method further improve the stability and accuracy of hoisting, which can meet the high standard requirements of hoisting operations in the shipbuilding and repair industry.

[0046] In use, push the upright frame 11 to move the device directly above the workpiece to be hoisted via the casters 111, and then press down the brake pads of the casters 111 to fix the frame 1. Use external traction force to drive the first traction component 21 to slide synchronously along the upper crossbeam 13 guide rail and the second traction component 23 to slide synchronously along the lower crossbeam 12 guide rail, so that the hook 26 is directly opposite the workpiece lifting point, stop traction, and fix the components with the limiting structure.

[0047] Lower hook 26, open its safety latch and engage it with the workpiece lifting point. After confirming it is secure, close the latch. Press the "Up" button on control switch 27. The winch 24 drives the wire rope, lifting device connector 25, and hook 26 to lift the workpiece. Using guide rod 222 to prevent swaying, press "Stop" after reaching a safe height. Drive the two traction components to move synchronously, bringing the workpiece above the target installation position, and stop traction. Press the "Down" button on control switch 27 to slowly lower the workpiece to the installation position. After alignment, press "Stop". Open the hook 26 latch to release the workpiece, raise hook 26, loosen the universal wheel 111 brake pads and move the device to the storage area for fixation, and disconnect the power to winch 24.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
