Description

Technical Field

[0001] This utility model relates to the field of slide well hoisting, and in particular to a slide well beam hoisting device. Background Technology

[0002] Against the backdrop of the booming shipbuilding industry and the continuous growth in demand for ship repair and construction, the construction of ship launching slipways has attracted increasing attention. There are two main methods for slipway construction: cast-in-place and precast lattice beam assembly. Cast-in-place methods require the construction of cofferdams, which can have a significant impact on the surrounding environment and are subject to many limitations in practical applications. Therefore, precast lattice beam assembly has become a common method for comb-type slipway construction.

[0003] However, underwater installation and positioning of precast lattice beams faces numerous challenges. Traditional installation measurements often utilize inverted frames, but during the hoisting phase, steel bars are typically pierced for lifting the lattice beams. This method suffers from poor stability, and the wire ropes are prone to colliding with the inverted frames during construction, severely impacting construction safety and efficiency, and making it difficult to guarantee the accuracy of the lattice beam installation. These problems urgently require a new lifting and hoisting device for lattice beams to effectively solve, in order to meet the requirements of construction quality and efficiency for ship launching ramp construction. Utility Model Content

[0004] The main purpose of this utility model is to provide a lifting and hoisting device for a sliding track grid beam, which solves the problem that traditional installation and measurement often use inverted frames, but in the hoisting stage, steel bars are often used to pierce holes for hoisting the grid beam. This method has poor stability, and the steel wire rope is very likely to collide with the inverted frame during construction, which seriously affects construction safety and efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a sliding track grid beam lifting and hoisting device, including a grid beam support base and a hoisting structure. The grid beam is set on the grid beam support base, and the inclined surface of the lower surface of the hoisting structure is in contact with the upper surface of the grid beam so that the upper surface of the hoisting structure is in a horizontal state.

[0006] The lifting device structure is connected to the threaded rod reserved on the upper surface of the grid beam by nuts. The lifting device structure is provided with lifting device support structures on both sides, and the lifting device support structures are provided with retractable inclined support frames.

[0007] The hoisting rope of the trolley passes around the end of the inclined support frame and connects to the hoisting hole of the grid beam.

[0008] In the preferred embodiment, the lower part of the lifting support structure is located on one side of the lifting structure, and the upper part of the lifting support structure is connected to multiple fixed crossbars on one side of the measuring inverted frame.

[0009] In the preferred embodiment, the lifting device support structure includes a quadrilateral frame structure composed of four frame support rods. At least two second connecting rods are hinged at the lower part of the frame structure. The other end of the second connecting rod is hinged to one end of the inclined support frame, and the other end of the inclined support frame is hinged to the first connecting rod. The two ends of the first connecting rod are slidably connected to the two sides of the frame.

[0010] In the preferred embodiment, the middle part of the second connecting rod consists of two rods, which are connected by a second connecting hinge. One rod is equipped with a limiter, and the other rod abuts against the upper limit of the limiter, so that the second connecting rod is laterally positioned to support the inclined support frame.

[0011] In the preferred embodiment, the frame is provided with sliding grooves on both sides, the two ends of the first connecting rod are slidably connected to the sliding grooves, and the sliding grooves are provided with protruding limiting blocks.

[0012] When the first connecting rod abuts against the limiting block, the inclined support frame unfolds; when the first connecting rod abuts against the upper end of the slide groove, the inclined support frame retracts.

[0013] In the preferred embodiment, a buckle is provided at the lower end of the frame, and when the inclined support frame retracts, the end of the inclined support frame is locked onto the buckle for fixation.

[0014] In the preferred embodiment, the grid beam support base is provided with two high supports and two low supports. The two high supports and two low supports are connected by multiple connecting rods to form the grid beam support base. Multiple anti-slip pads are provided on the high supports.

[0015] In the preferred embodiment, a first hydraulic cylinder is provided inside the high support, and the end of the upper telescopic rod of the first hydraulic cylinder is connected to the anti-slip pad.

[0016] The low support is equipped with a second hydraulic cylinder, and the end of the extension rod of the second hydraulic cylinder is equipped with a top plate.

[0017] In the preferred embodiment, the lifting equipment includes a bridge erecting machine, which is set on the auxiliary piles by multiple outriggers. The tops of the horizontally set auxiliary piles are connected by a horizontal moving track, which covers the entire pile foundation group. The movement range of the bridge erecting machine covers the entire pile foundation group.

[0018] The bridge erecting machine is equipped with multiple lifting trolleys on top, and the lifting ropes of the trolleys are connected to the grid beam.

[0019] This invention provides a lifting and hoisting device for a sliding track grid beam. By measuring the GPS positioning device on the inverted frame and providing real-time feedback on the grid beam's position, combined with a precise positioning algorithm, the device can continuously adjust the grid beam's position, keeping the installation deviation within a very small range and ensuring that the grid beam is accurately installed on the target pile foundation. This significantly improves installation accuracy compared to traditional methods.

[0020] The stable connection between the lifting device structure and the grid beam, as well as the reasonable design of the inclined support frame in the lifting device support structure, provide reliable support for the hoisting of the grid beam, avoid swaying and displacement during the hoisting process, enhance construction stability, and reduce safety risks.

[0021] The unique lifting device design effectively solves the problem of easy conflict between the wire rope and the measuring inverted frame, ensuring smooth construction, reducing construction failures and delays, and improving construction efficiency.

[0022] The structural design of the grid beam support base allows it to adapt to different situations, such as adjusting the height and level through hydraulic cylinders; the retractable design of the lifting support structure facilitates installation and disassembly, making construction operations easier, reducing construction time and labor costs, and improving construction efficiency.

[0023] This system and method are applicable to the hoisting and installation of the grid beams for the entire pile foundation group.

[0038] Example 1

[0039] like Figure 1-11 As shown, a sliding track grid beam lifting and hoisting device includes a grid beam support base 1 and a hoisting structure 3. The grid beam 8 is set on the grid beam support base 1, and the inclined surface of the lower surface of the hoisting structure 3 is attached to the upper surface of the grid beam 8 so that the upper surface of the hoisting structure 3 is in a horizontal state.

[0040] The lifting structure 3 is connected to the threaded rod reserved on the upper surface of the grid beam 8 by a nut. The lifting structure 3 is provided with lifting support structure 2 on both sides, and the lifting support structure 2 is provided with a retractable inclined support frame 204.

[0041] The hoisting rope 13 of the trolley 9 passes around the end of the inclined support frame 204 and connects to the hoisting hole 801 of the grid beam 8.

[0042] The tightness and stability of the connection between the lower surface of the lifting device structure 3 and the upper surface of the grid beam 8 are ensured by the inclined contact and nut connection, keeping the upper surface of the lifting device structure 3 horizontal and providing a stable foundation for subsequent operations. The retractable inclined support frame 204 on the lifting device support structure 2 provides an effective support point for the lifting rope 13 of the lifting trolley 9. The lifting rope 13 passes around its end and connects to the lifting hole 801 of the grid beam 8. During the lifting process, the force can be reasonably distributed, which effectively enhances the stability and safety of the lifting operation. It helps to ensure the accuracy of the posture and position of the grid beam 8 during the lifting and installation process, thereby improving construction efficiency and quality, and reducing safety risks and construction errors caused by unstable lifting.

[0043] Connecting the precast grid beams to the hoisting system: During the installation process, after the detachable connecting beam 302 is installed, the precast grid beam 8 and the hoisting device 3 are connected by steel wire ropes, so that the hoisting device 3 can bear the weight of the grid beam 8 and realize the hoisting operation. It is a key connecting component for hoisting the grid beam 8 from the grid beam support 1 and transporting it to the designated installation position.

[0044] To avoid conflict with the measuring inverted frame: its structural design avoids conflict between the wire rope and the measuring inverted frame 4 during the installation of the grid beam 8. In traditional methods, the wire rope and the inverted frame are prone to conflict in position. However, this lifting device 3, through its reasonable construction, such as the ingenious placement of the detachable connecting beam 302 within the frame structure of the measuring inverted frame 4, ensures that the two do not interfere with each other during installation, guaranteeing safe and reliable construction. This ensures that the measuring inverted frame 4 can accurately measure the spatial position changes of the precast grid beam 8 without affecting the measurement accuracy.

[0045] Auxiliary Measurement and Subsequent Operations: After the precast grid beam 8 is installed, the grid beam 8 is separated from the hanger 3. By installing a limiting device 303 on the hanger connecting beam 302, the lifting device 3 can fix the measuring frame 4 to itself, facilitating subsequent operations. For example, during the process of moving the measuring frame 4 and the lifting device 3 as a whole to the temporary support on the shore and completing the connection between the next precast grid beam 8 and the measuring frame 4, the lifting device 3 plays a role in supporting and transferring the measuring frame 4, which contributes to the continuity and efficiency of construction.

[0046] In the preferred embodiment, the lower part of the lifting support structure 2 is located on one side of the lifting structure 3, and the upper part of the lifting support structure 2 is connected to multiple fixed crossbars 401 on one side of the measuring inverted frame 4.

[0047] In the preferred embodiment, the lifting support structure 2 includes a quadrilateral frame structure composed of four frame support rods 201. At least two second connecting rods 203 are hinged at the lower part of the frame structure. The other end of the second connecting rod 203 is hinged to one end of the inclined support frame 204, and the other end of the inclined support frame 204 is hinged to the first connecting rod 202. The two ends of the first connecting rod 202 are slidably connected to the two sides of the frame.

[0048] In the preferred embodiment, the second connecting rod 203 is divided into two rods, which are connected by a second connecting hinge 208. One rod is provided with a limiter 210, and the other rod abuts against the upper limit of the limiter 210, so that the second connecting rod 203 is laterally provided with a support for the inclined support frame 204.

[0049] In the preferred embodiment, the frame is provided with sliding grooves 205 on both sides, the two ends of the first connecting rod 202 are slidably connected to the sliding grooves 205, and the sliding grooves 205 are provided with protruding limiting blocks inside;

[0050] When the first connecting rod 202 abuts against the limiting block, the inclined support frame 204 unfolds; when the first connecting rod 202 abuts against the upper end of the slide groove 205, the inclined support frame 204 retracts.

[0051] In the preferred embodiment, a buckle 206 is provided on the lower end of the frame. When the inclined support frame 204 is retracted, the end of the inclined support frame 204 is fixed by the buckle 206.

[0052] The lower part of the lifting support structure 2 is located on one side of the lifting structure 3, and the upper part is connected to multiple fixed crossbars 401 on one side of the measuring inverted frame 4. It serves to connect the lifting structure 3 and the measuring inverted frame 4, providing structural support and connection for the entire lifting system and ensuring that all components work together.

[0053] The quadrilateral frame structure composed of four frame support rods 201 forms the basic frame of the lifting device support structure 2, providing an installation foundation and stable support frame for other components, and ensuring the shape and strength of the entire lifting device support structure 2.

[0054] The second connecting rod 203 has one end hinged to the lower part of the frame structure and the other end hinged to the inclined support frame 204. It is also partially composed of two rods connected by the second connecting hinge 208. One rod is equipped with a limiter 210, and the other rod abuts against the upper limit of the limiter 210, so that the second connecting rod 203 can be set laterally to support the inclined support frame 204. In the unfolded state, it provides stable support force for the inclined support frame 204, ensuring the stability of the structure during hoisting.

[0055] The inclined support frame 204 is hinged at one end to the second connecting rod 203 and at the other end to the first connecting rod 202. With the cooperation of the first connecting rod 202, it provides a support point for the lifting rope 13 of the lifting trolley 9, allowing the rope 13 to pass around its end and connect to the lifting hole 801 of the grid beam 8. Its structural design avoids conflict between the wire rope and the measuring inverted frame 4 during the installation of the grid beam 8. In traditional methods, the wire rope and the inverted frame are prone to conflict. However, this lifting device 3, through its reasonable construction, such as the clever placement of the detachable connecting beam 302 within the frame structure of the measuring inverted frame 4, ensures that the two do not interfere with each other during installation, guaranteeing safe and reliable construction. This ensures that the measuring inverted frame 4 can accurately measure the spatial position changes of the precast grid beam 8 without affecting measurement accuracy.

[0056] The first connecting rod 202 is slidably connected to the slide grooves 205 on both sides of the frame at both ends. The expansion and retraction of the inclined support frame 204 are controlled by sliding within the slide grooves 205. When it abuts against the limiting block inside the slide groove 205, the inclined support frame 204 is expanded. When it abuts against the upper end of the slide groove 205, the inclined support frame 204 is retracted, which facilitates the adjustment of the state of the lifting support structure 2 at different construction stages.

[0057] Slide 205: Located on both sides of the frame, the limiting block inside it is used to limit the position of the first connecting rod 202, thereby controlling the unfolding and retracting state of the inclined support frame 204, providing guidance and limiting function for the sliding of the first connecting rod 202, and ensuring the normal operation of the lifting support structure 2.

[0058] Buckle 206: Located at the lower end of the frame, when the inclined support frame 204 is retracted, its end is locked onto buckle 206 to prevent the inclined support frame 204 from shaking freely in the non-working state and to ensure the storage stability of the lifting support structure 2.

[0059] In the preferred embodiment, the grid beam support base 1 is provided with two high supports 102 and two low supports 101. The two high supports 102 and the two low supports 101 are connected by multiple connecting rods 103 to form the grid beam support base 1. Multiple anti-slip pads 104 are provided on the high supports 102.

[0060] In the preferred embodiment, a first hydraulic cylinder 105 is provided inside the high support 102, and the end of the telescopic rod at the upper end of the first hydraulic cylinder 105 is connected to the anti-slip pad 104.

[0061] The low support 101 is equipped with a second hydraulic cylinder 106, and the end of the telescopic rod of the second hydraulic cylinder 106 is equipped with a top plate.

[0062] The grid beam support base 1 serves as the basic support structure of the entire system, used to place the grid beam 8 and provide a stable support platform for the grid beam 8, ensuring that the position of the grid beam 8 is relatively fixed during the installation process. It is composed of two high supports 102, two low supports 101 and multiple connecting rods 103, which ensures the strength and stability of the overall structure.

[0063] The high support 102 is an important component of the grid beam bracket base 1. Together with the low support 101 and connecting rod 103, it supports the grid beam 8. Multiple anti-slip pads 104 installed on it increase the friction between the grid beam 8 and the support, preventing slippage during placement or adjustment and further ensuring its positional stability. The internal first hydraulic cylinder 105 can extend and retract to adjust the height of the anti-slip pads 104, facilitating fine-tuning of the grid beam 8's level and height to adapt to different installation requirements.

[0064] The low support 101 works in conjunction with the high support 102 to support the grid beam 8. The top plate at the end of the telescopic rod of the second hydraulic cylinder 106 inside it can assist in supporting the grid beam 8 to a certain extent. It can also make fine adjustments to the position of the grid beam 8 through the telescopic function of the hydraulic cylinder, and together with the high support 102, ensure that the grid beam 8 is in the appropriate initial installation position.

[0065] The connecting rod 103 connects two high supports 102 and two low supports 101, forming an integral grid beam support base 1 structure, which enhances the rigidity and stability of the entire support base and ensures that it will not deform or shift when bearing the weight of the grid beam 8 and external forces.

[0066] Anti-slip pads 104 are installed on the high support 102 to prevent the grid beam 8 from sliding on the bracket base by increasing friction, ensuring the stability of the grid beam 8 and providing a reliable foundation for subsequent installation operations.

[0067] The first hydraulic cylinder 105 is located inside the high support 102. Its upper telescopic rod is connected to the anti-slip pad 104. Through its own telescopic movement, it drives the anti-slip pad 104 to rise and fall, thereby achieving precise adjustment of the height and level of the grid beam 8 and meeting the precision requirements during the installation process.

[0068] The second hydraulic cylinder 106 is located inside the low support 101. The top plate at the end of its telescopic rod can provide auxiliary support for the grid beam 8 and assist in adjusting the position of the grid beam 8 through its telescopic function. Together with the first hydraulic cylinder 105 inside the high support 102, it ensures the installation accuracy and stability of the grid beam 8.

[0069] In the preferred embodiment, the lifting equipment includes a bridge erecting machine 10, which is mounted on the auxiliary piles 6 via multiple outriggers 11. The tops of the horizontally positioned auxiliary piles 6 are connected by a horizontal moving track 12, which covers the entire pile foundation group. The moving range of the bridge erecting machine 10 covers the entire pile foundation group.

[0070] The bridge erecting machine 10 is equipped with multiple lifting trolleys 9 on its top, and the lifting ropes 13 of the lifting trolleys 9 are connected to the grid beam 8.

[0071] As the core component of the lifting equipment, the bridge erecting machine 10 is stably mounted on the auxiliary piles 6 via multiple outriggers 11. Its range of movement can cover the entire pile foundation group, and it can move freely on the transverse moving track 12, thereby accurately reaching the position above each pile foundation. It provides support and a moving platform for the lifting trolley 9, realizing the lifting operation of the grid beam 8. It is the key equipment in the entire lifting system that undertakes the main lifting tasks.

[0072] The outrigger 11 connects the bridge erecting machine 10 to the auxiliary pile 6, evenly transferring the weight of the bridge erecting machine 10 to the auxiliary pile 6, ensuring the stability of the bridge erecting machine 10 during operation, preventing it from shaking or shifting, and providing a reliable support foundation for the normal operation of the bridge erecting machine 10.

[0073] The auxiliary pile 6 serves as the supporting foundation for the bridge erecting machine 10. In conjunction with the outrigger 11, it bears various loads on the bridge erecting machine 10 and during the hoisting process, ensuring that the bridge erecting machine 10 is in a stable state during operation and providing solid ground support for the entire hoisting operation.

[0074] Lateral moving track 12: laid on top of the lateral auxiliary piles 6, connecting each auxiliary pile 6, so that the bridge erecting machine 10 can move laterally smoothly above it, covering the entire pile foundation group, expanding the working range of the bridge erecting machine 10, ensuring that the well beam 8 can be hoisted on pile foundations at different locations, and improving construction efficiency and flexibility.

[0075] The lifting trolley 9 is set on top of the bridge erecting machine 10 and is connected to the grid beam 8 by the hoisting rope 13. With the movement and support of the bridge erecting machine 10, the hoisting rope 13 is used to lift and lower the grid beam 8. It is the lifting component that directly acts on the grid beam 8 and is responsible for lifting the grid beam 8 from the grid beam support base 1 and transporting it to the designated installation position.

[0076] The lifting rope 13 connects the lifting trolley 9 and the grid beam 8. Driven by the lifting trolley 9, it bears the weight of the grid beam 8, realizes the vertical lifting of the grid beam 8, moves the grid beam 8 between different heights, and ensures that the grid beam 8 can be accurately installed on the target pile foundation.

[0077] Example 2

[0078] Further explanation in conjunction with Example 1, such as Figure 1-11 As shown in the structure, S1, install the grid beam support base 1 at the construction site, place the two high supports 102 and the two low supports 101 in the design position, and connect them with multiple connecting rods 103 to ensure a firm connection and form a stable grid beam support base structure.

[0079] Multiple anti-slip pads 104 are installed on the high support 102, and a first hydraulic cylinder 105 is installed inside the high support 102 so that the end of its upper telescopic rod is connected to the anti-slip pad 104; a second hydraulic cylinder 106 is installed inside the low support 101 so that a top plate is provided at the end of its telescopic rod.

[0080] S2. Install the assembled lifting support structure 2 on both sides of the lifting structure 3, so that the lower part of the lifting support structure 2 is located on one side of the lifting structure 3, and connect its upper part to multiple fixed crossbars 401 on one side of the measuring inverted frame 4.

[0081] S3. Use lifting equipment to hoist the prefabricated grid beam 8 to the top of the grid beam support base 1, and slowly lower the grid beam 8 to accurately place it on the grid beam support base 1. The grid beam 8 is supported by the high support 102 and the low support 101.

[0082] Start the first hydraulic cylinder 105 inside the high support 102 and the second hydraulic cylinder 106 inside the low support 101 to adjust the height and level of the grid beam 8 so that the grid beam 8 is in a suitable initial installation position, and check the stability of the grid beam 8.

[0083] S4. Place the lifting structure 3 on the grid beam 8, so that the inclined surface of the lower surface of the lifting structure 3 is in contact with the upper surface of the grid beam 8, and ensure that the upper surface of the lifting structure 3 is horizontal. Use nuts to firmly connect the lifting structure 3 to the pre-reserved screw on the upper surface of the grid beam 8 to ensure the reliability of the connection.

[0084] S5. Deploy the inclined support frame 204 and push the first connecting rod 202 to abut against the limiting block inside the slide groove 205. At this time, the inclined support frame 204 is in the deployed state, providing support for subsequent rope connection.

[0085] The hoisting rope 13 of the hoisting trolley 9 is passed around the end of the inclined support frame 204 and connected to the hoisting hole 801 of the grid beam 8;

[0086] S6. The method for hoisting and positioning the grid beam is as follows:

[0087] A two-dimensional Cartesian coordinate system is established for the entire pile foundation group, and the origin and coordinate axis directions of the coordinate system are determined. The coordinate position of each pile foundation in the coordinate system is recorded to form a pile foundation coordinate database. It is ensured that the bridge erecting machine 10 can obtain its own position information in the coordinate system and communicate well with the control system, and can receive and execute positioning commands.

[0088] According to the construction plan, the coordinates of the target pile foundation location where the grid beam 8 needs to be installed have been determined. Extract the information of the target pile foundation from the pile foundation coordinate database;

[0089] The GPS positioning device on the measuring inverted frame 4 of the grid beam 8 obtains the current position coordinates of the grid beam 8 in real time. And transmit the location information to the control system;

[0090] The control system calculates the deviations between the current position and the target position of the grid beam 8 in the X and Y axis directions:

[0091] ;

[0092] ;

[0093] Based on the positional deviation, the control system sends an adjustment command to the bridge erecting machine (10):

[0094] if Then control the bridge erecting machine 10 to move in the positive X-axis direction. Distance; if Then it will move in the negative X-axis direction. distance;

[0095] if Then control the bridge erecting machine 10 to move in the positive Y-axis direction. Distance; if Then it moves in the negative Y-axis direction. distance;

[0096] After the bridge erecting machine 10 performs the adjustment action, wait for a period of time to allow the grid beam 8 to stabilize in the new position, and then obtain the position information of the inverted frame 4 again. Repeat steps three to five until the position deviation of the grid beam 8 is within the allowable accuracy range.

[0097] Once the grid beam 8 reaches the designated position and meets the accuracy requirements, the control system sends an installation command to the bridge erecting machine 10. The bridge erecting machine 10 slowly lowers the grid beam 8 onto the target pile foundation and continuously monitors the position during the installation process to ensure the accuracy of the installation.

[0098] S7. Slowly lower the grid beam 8 to the installation position and ensure it is accurately aligned with the pile foundation 5 below to complete the installation and fixing.

[0099] After the grid beam 8 is installed, loosen the connection between the lifting rope 13 and the lifting hole 801 of the grid beam 8, and the lifting rope 13 is connected to the lifting support structure 2;

[0100] Push the first connecting rod 202 to abut against the upper end of the slide groove 205, so that the inclined support frame 204 retracts and the end of the retracted inclined support frame 204 is locked onto the buckle 206 for fixation;

[0101] Remove the connecting nuts between the lifting structure 3 and the grid beam 8, and remove the lifting structure 3 from the grid beam 8. The lifting support structure 2 is used to remove the lifting structure 3 and the measuring inverted frame 4.
