[0002] With the rapid development of modern transportation networks, bridges, as important transportation infrastructure, are crucial to ensuring smooth traffic flow due to their safety and stability. In emergencies such as natural disasters, accidents or wars, bridges may be damaged and need to be repaired quickly and effectively to restore traffic.

[0003] Traditional bridge repair methods usually require a lot of manpower and material resources, as well as complex construction equipment, such as poles, jacks or cranes, etc. These methods are not only labor-intensive, but also cumbersome and require a large number of erection personnel, and are difficult to meet the needs of rapid repair. In addition, although the patent application with publication number CN113699900A, entitled A beam and pier structure for bridge repair and its application, has solved the problem of long assembly time and low efficiency of existing bridge repair work to a certain extent, the system used by this method is still relatively complex. Summary of the invention

[0004] In view of this, the present invention provides a hydraulic jacking system for emergency repair piers, which has a simple and compact structure and is easy to operate. It can complete the erection of the emergency repair piers in a short time to quickly restore traffic, reduce the demand for professional operators, and improve the flexibility and adaptability of construction.

[0036] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0037] Reference Figure 1 to Figure 5 A hydraulic lifting system for repairing piers comprises a base 1, a guide frame 2, a lifting frame 3, a hydraulic system 5, and a transmission mechanism 4, wherein:

[0038] The base 1 is used to be fixed on a preset foundation 14 to play a supporting role; the bottom of the guide frame 2 is fixedly connected to the base 1; the lifting frame 3 is sleeved on the periphery of the guide frame 2, and the height of the lifting frame 3 is less than the height of the guide frame 2, and the lifting frame 3 is used to lift the emergency repair pier 13; the hydraulic system is arranged on the base 1, and the hydraulic system includes an oil cylinder 11 and a pump station 12, and the piston rod of the oil cylinder 11 is vertically upward; the transmission mechanism includes a pulley 9 and a lifting belt 10; pulleys 9 are arranged on the top of the guide frame 2 and the piston rod of the oil cylinder 11; one end of the lifting belt 10 is fixed to the top of the lifting frame 3, and the other end is fixed to the guide frame 2 after passing through the pulley 9 (as a fixed pulley) on the top of the guide frame 3 and the pulley 9 (as a movable pulley) on the piston rod of the oil cylinder 11 in turn; when the pump station 12 controls the piston rod of the oil cylinder 11 to retract, the lifting belt 10 forms an upward pulling force on the lifting frame 3, so that the lifting frame 3 moves upward along the height direction of the guide frame 2, and the emergency repair pier 13 is lifted upward.

[0039] In this way, the hydraulic lifting system of the emergency repair pier 13 is a standard erection system with a simple and compact structure. It can lift the lifting frame 3 and the emergency repair pier 13 upward together through the pulley lifting mechanism composed of the hydraulic system 5, the lifting belt 10 and the pulley 9 to complete the erection of the emergency repair pier. No long-term assistance from large-scale mechanical equipment is required, and the labor intensity of the erection personnel is greatly reduced. The erection of the emergency repair pier 13 can be completed in a short time to quickly restore traffic, reducing the demand for professional operators and improving the flexibility and adaptability of construction.

[0040] Specifically, at least two transmission mechanisms 4 are symmetrically arranged, which improves the stability of the hydraulic lifting system of the emergency pier in lifting the emergency pier 13. In particular, in this embodiment, a total of four transmission mechanisms and four oil cylinders 11 are arranged, symmetrically distributed along the four corners of the hydraulic lifting system of the emergency pier.

[0041] Specifically, the guide frame 2 and the lifting frame 3 can be slidably matched through a slider or rolled matched through a roller, which facilitates the lifting movement of the lifting frame 3.

[0042] Specifically, the exhibition Figure 2 and Figure 4 The base 1 includes a cylinder base 6, a guide frame base 7, and a high pier base 8 (also called a repair pier base) arranged on the periphery of the cylinder base 6 and the guide frame base 7; the cylinder base 6 is used to support the cylinder 11; the guide frame base 7 is used to support the guide frame 2; the high pier base 8 is used to support the lifted repair pier 13.

[0043] More specifically, in this embodiment, the guide frame 2 and the lifting frame 3 are both modularly assembled space truss structures, which makes the hydraulic lifting system of the emergency repair pier have the advantages of convenient disassembly and assembly, strong interchangeability, and repeated use.

[0044] The working principle of the hydraulic lifting system of the emergency repair pier is as follows:

[0045] Reference Figure 5 , fix the high pier base 8 on the preset foundation 14, the guide frame 2 is fixed on the preset foundation 14 through the guide frame base 7, and the cylinder 11 is fixed on the preset foundation 14 through the cylinder base 6. The pulley 9 is arranged on the top of the guide frame 2 and the piston rod of the cylinder 11, one end of the lifting belt 10 is fixed to the top of the lifting frame 3, and the other end is fixed to the guide frame 2 after passing through the pulley 9 on the top of the guide frame 2 and the pulley 9 on the piston rod of the cylinder 11 in turn. When the pump station 12 controls the piston rod of the cylinder 11 to contract, the lifting belt 10 forms an upward pulling force on the lifting frame 3, so that the lifting frame 3 moves upward along the height direction of the guide frame 2, and lifts the emergency repair pier 13 upward. Of course, if the lifting height of the emergency repair pier 13 exceeds the required height, the piston rod of the cylinder 11 can be controlled by the pump station 12 to extend upward to lower the lifting frame 3. It should be noted that, referring to Figure 5 and Figure 6In this embodiment, the emergency repair pier is a detachable splicing structure of multiple sections of emergency repair piers. When lifting, it is a step-by-step lifting, lifting one section at a time. When the previous section is lifted, the next section is manually hung on (or connected to) the lower end of the previous section. When the previous section is lifted, the newly connected section is also in place. When the lifting frame 3 is lifted, the cap beam 15 is initially located outside the guide frame 2 to avoid interference between the cap beam 15 and the guide frame 2. When the height of the cap beam 15 connected to the uppermost section exceeds the height of the guide frame 2, the operator climbs to the height of the cap beam 15 with the help of a climbing frame (which can be arranged inside the guide frame 2 with a spatial truss structure), moves the cap beam 15 to the middle of the guide frame 2, and connects the two ends of the cap beam 15 to the emergency repair pier, and then continues to lift to a higher set height. After the lifting is completed, the bottom support of the lowest section of the emergency repair pier is fixed on the high pier base 8.

[0046] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
