DETAILED DESCRIPTION

[0023] Example 1 like Figure 1-11 As shown, a slideway cross beam lifting and hoisting system comprises a cross beam support base 1 and a sling structure 3, a cross beam 8 is arranged on the cross beam support base 1, and the inclined surface of the lower surface of the sling structure 3 is fitted with the upper surface of the cross beam 8 so that the upper surface of the sling structure 3 is in a horizontal state; The hanger structure 3 is connected to the screws reserved on the upper surface of the cross beam 8 through nuts, and hanger support structures 2 are provided on both sides of the hanger structure 3, and a retractable oblique support frame 204 is provided on the hanger support structure 2; The lifting rope 13 of the lifting trolley 9 passes around the end of the oblique support frame 204 and is connected to the lifting hole 801 of the cross beam 8.

[0024] The tightness and stability of the connection between the lower surface of the sling structure 3 and the upper surface of the cross beam 8 are ensured by the bevel fit and the nut connection, so that the upper surface of the sling structure 3 remains horizontal, providing a stable foundation for subsequent operations. The retractable oblique support frame 204 on the sling support structure 2 provides an effective support point for the lifting rope 13 of the lifting trolley 9. The lifting rope 13 passes through its end and connects to the lifting hole 801 of the cross beam 8. During the lifting process, the force can be reasonably dispersed, which effectively enhances the stability and safety of the lifting operation, helps to ensure the posture and position accuracy of the cross beam 8 during the lifting and installation process, thereby improving the construction efficiency and quality, and reducing the safety risks and construction errors caused by unstable lifting.

[0025] Connect the prefabricated crisscross beam with the lifting system: During the installation process, after the detachable connecting beam 302 is installed, the prefabricated crisscross beam 8 is connected to the lifting fixture 3 through a steel wire rope, so that the lifting fixture 3 can bear the weight of the crisscross beam 8 and realize the lifting operation. It is a key connecting component for lifting the crisscross beam 8 from the crisscross beam bracket 1 and transporting it to the designated installation location.

[0026] Avoid conflict with the measuring inverted frame: Its structural design avoids the conflict between the wire rope and the measuring inverted frame 4 during the installation of the crisscross beam 8. In the traditional method, the wire rope and the inverted frame are prone to conflict, but the present sling 3 has a reasonable structure, such as the ingenious arrangement of the detachable connecting beam 302 in the frame structure of the measuring inverted frame 4, so that the two can not interfere with each other during the installation process, ensuring the safe and reliable construction, and ensuring that the measuring inverted frame 4 can accurately measure the spatial position change of the prefabricated crisscross beam 8 without affecting the measurement accuracy.

[0027] Auxiliary measurement and subsequent operations: After the prefabricated cross beam 8 is installed, the cross beam 8 is separated from the hanger 3. By installing the limit device 303 on the hanger connecting beam 302, the hanger 3 can fix the measuring frame 4 and itself, which is convenient for subsequent operations. For example, when the measuring frame 4 and the hanger 3 are adjusted to the temporary support on the shore as a whole and the next prefabricated cross beam 8 is connected to the measuring frame 4, the hanger 3 plays the role of supporting and transferring the measuring frame 4, which is conducive to the continuity and efficiency of the construction.

[0028] In the preferred embodiment, the lower portion of the sling support structure 2 is arranged on one side of the sling structure 3 , and the upper portion of the sling support structure 2 is connected to a plurality of fixed cross bars 401 on one side of the measuring inverted frame 4 .

[0029] In the preferred embodiment, the sling support structure 2 includes a frame structure of a quadrilateral structure formed by four frame support rods 201, at least two second connecting rods 203 are hinged at the lower position of the frame structure, the other end of the second connecting rod 203 is hinged to one end of the oblique support frame 204, the other end of the oblique support frame 204 is hinged to the first connecting rod 202, and the two ends of the first connecting rod 202 are slidably connected to the two sides of the frame.

[0030] In the preferred embodiment, the middle part of the second connecting rod 203 is divided into two rods, which are connected by a second connecting hinge 208. A limiter 210 is provided on one rod, and the other rod rests against the upper limit of the limiter 210, so that the second connecting rod 203 is laterally arranged to support the oblique support frame 204.

[0031] In the preferred embodiment, a slide groove 205 is provided on both sides of the frame, and both ends of the first connecting rod 202 are slidably connected to the slide groove 205, and a raised limit block is provided inside the slide groove 205; When the first connecting rod 202 abuts against the limiting block, the oblique support frame 204 is deployed, and when the first connecting rod 202 abuts against the upper end of the sliding groove 205, the oblique support frame 204 is retracted.

[0032] In a preferred embodiment, a buckle 206 is provided on the lower end of the frame, and when the oblique support frame 204 is retracted, the end of the oblique support frame 204 is clamped on the buckle 206 and fixed.

[0033] The sling support structure 2: Its lower part is arranged on one side of the sling structure 3, and its upper part is connected to a plurality of fixed cross bars 401 on one side of the measuring inverted frame 4, which serves to connect the sling structure 3 and the measuring inverted frame 4, providing structural support and connection relationship for the entire lifting system, and ensuring that all components work together.

[0034] The quadrilateral frame structure composed of four frame support rods 201 constitutes the basic frame of the hanger support structure 2, provides an installation foundation and a stable support frame for other components, and ensures the shape and strength of the entire hanger support structure 2.

[0035] The second connecting rod 203: one end of which is hinged to the lower part of the frame structure, and the other end is hinged to the oblique support frame 204, and part of it is two rods connected by a second connecting hinge 208, one of the rods is provided with a limiter 210, and the other rod rests on the upper limit of the limiter 210, so that the second connecting rod 203 can be horizontally arranged to support the oblique support frame 204, and provide a stable supporting force for the oblique support frame 204 in the unfolded state, thereby ensuring the stability of the structure during the lifting process.

[0036] The oblique support frame 204: one end is hinged to the second connecting rod 203, and the other end is hinged 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, so that the lifting rope 13 can bypass its end and connect with the lifting hole 801 of the cross beam 8. Its structural design avoids the conflict between the wire rope and the measuring inverted frame 4 during the installation of the cross beam 8. In the traditional method, the position of the wire rope and the inverted frame is prone to conflict, but the present sling 3 has a reasonable structure, such as the ingenious setting of the detachable connecting beam 302 in the frame structure of the measuring inverted frame 4, so that the two can not interfere with each other during the installation process, ensuring safe and reliable construction, and ensuring that the measuring inverted frame 4 can accurately measure the spatial position change of the prefabricated cross beam 8 without affecting the measurement accuracy.

[0037] The first connecting rod 202: Both ends are slidably connected to the slide grooves 205 on both sides of the frame, and the expansion and retraction of the oblique support frame 204 are controlled by sliding in the slide grooves 205. When the oblique support frame 204 abuts against the limit block inside the slide groove 205, the oblique support frame 204 is expanded, and when it abuts against the upper end of the slide groove 205, the oblique support frame 204 is retracted, so as to facilitate the adjustment of the state of the sling support structure 2 at different construction stages.

[0038] Slide groove 205: It is arranged on both sides of the frame, and the limit block inside it is used to limit the position of the first connecting rod 202, so as to control the expansion and retraction state of the oblique support frame 204, provide guidance and limit for the sliding of the first connecting rod 202, and ensure the normal operation of the sling support structure 2.

[0039] Buckle 206: It is arranged at the lower end of the frame. When the oblique support frame 204 is retracted, its end is clamped on the buckle 206 and fixed, so as to prevent the oblique support frame 204 from shaking randomly in the non-working state, thereby ensuring the storage stability of the sling support structure 2.

[0040] In the preferred embodiment, the cross-beam support base 1 is provided with two high supports 102 and two low supports 101 , and the two high supports 102 and the two low supports 101 are connected by multiple connecting rods 103 to form the cross-beam support base 1 , and multiple anti-slip pads 104 are provided on the high supports 102 .

[0041] 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; A second hydraulic cylinder 106 is disposed inside the short support 101 , and a top plate is disposed at the end of the telescopic rod of the second hydraulic cylinder 106 .

[0042] The cross-beam support base 1 serves as the basic supporting structure of the entire system, and is used to place the cross-beam 8, providing a stable supporting platform for the cross-beam 8, ensuring that the position of the cross-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.

[0043] The high support 102 is an important part of the cross beam support base 1, and cooperates with the low support 101 and the connecting rod 103 to support the cross beam 8. The multiple anti-skid pads 104 arranged on it can increase the friction between the cross beam 8 and prevent the cross beam 8 from sliding during placement or adjustment, and further ensure its stable position; the first hydraulic cylinder 105 inside can adjust the height of the anti-skid pads 104 by telescoping, so as to facilitate fine-tuning the levelness and height of the cross beam 8 to meet different installation requirements.

[0044] The low support 101 works in conjunction with the high support 102 to support the cross 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 cross beam 8 to a certain extent, and can also fine-tune the position of the cross beam 8 through the telescopic function of the hydraulic cylinder, and together with the high support 102, ensure that the cross beam 8 is in a suitable initial installation position.

[0045] The connecting rod 103 connects the two high supports 102 and the two short supports 101, so that they form an integral cross-beam support base 1 structure, thereby enhancing the rigidity and stability of the entire support base and ensuring that no deformation or displacement occurs when bearing the weight of the cross-beam 8 and external forces.

[0046] The anti-skid pad 104 is arranged on the high support 102 to prevent the cross beam 8 from sliding on the bracket base by increasing the friction force, thereby ensuring the stability of the cross beam 8 and providing a reliable basic condition for subsequent installation operations.

[0047] The first hydraulic cylinder 105 is located inside the high support 102, and its upper telescopic rod is connected to the anti-skid pad 104. It drives the anti-skid pad 104 to rise and fall through its own telescopic action, thereby achieving precise adjustment of the height and level of the cross beam 8 to meet the accuracy requirements during the installation process.

[0048] The second hydraulic cylinder 106 is inside the short support 101, and the top plate at the end of its telescopic rod can provide auxiliary support for the cross beam 8, and assist in adjusting the position of the cross beam 8 through the telescopic function, and work together with the first hydraulic cylinder 105 in the high support 102 to ensure the installation accuracy and stability of the cross beam 8.

[0050] As the core part of the lifting equipment, the bridge erecting machine 10 is stably set on the auxiliary pile 6 through multiple legs 11. Its moving range can cover the entire pile foundation group and can move freely on the transverse moving track 12, so that it can accurately reach the top of each pile foundation position, provide support and mobile platform for the lifting trolley 9, and realize the lifting operation of the cross beam 8. It is the key equipment that undertakes the main lifting tasks in the entire lifting system.

[0051] The legs 11 connect the bridge erecting machine 10 and the auxiliary piles 6, and evenly transfer the weight of the bridge erecting machine 10 to the auxiliary piles 6, thereby 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.

[0052] The auxiliary piles 6 serve as the supporting foundation of the bridge erecting machine 10 and cooperate with the legs 11 to bear the various loads of the bridge erecting machine 10 and the lifting process, ensuring that the bridge erecting machine 10 is in a stable state during operation and providing solid ground support for the entire lifting operation.

[0053] Transverse moving track 12: laid on the top of the laterally arranged auxiliary piles 6, connecting each auxiliary pile 6, so that the bridge-building machine 10 can move laterally smoothly above it, covering the entire pile foundation group, expanding the operation range of the bridge-building machine 10, ensuring that the cross-shaped beam 8 can be hoisted on the pile foundations at different positions, and improving construction efficiency and flexibility.

[0054] The lifting trolley 9 is arranged on the top of the bridge-building machine 10 and is connected to the cross-beam 8 through a lifting rope 13. Under the movement and support of the bridge-building machine 10, the lifting rope 13 is used to realize the lifting and lowering operations of the cross-beam 8. It is a lifting component that directly acts on the cross-beam 8 and is responsible for lifting the cross-beam 8 from the cross-beam support base 1 and transporting it to the designated installation position.

[0055] The lifting rope 13 connects the lifting trolley 9 and the cross beam 8.
