Description

Technical Field

[0001] This utility model belongs to the field of emergency response technology for repair piers, specifically relating to a hydraulic jacking system for repair piers. Background Technology

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

[0003] Traditional bridge repair methods typically require substantial manpower and resources, as well as complex construction equipment such as derricks, jacks, or cranes. These methods are not only labor-intensive and cumbersome, requiring a large number of personnel, but also fail to meet the demands of rapid repairs. Furthermore, while patent application CN113699900A, entitled "A Beam-Pier Structure for Bridge Repair and Its Application," addresses to some extent the problems of long assembly times and low efficiency in existing bridge repair work, the system used in this method remains relatively complex. Utility Model Content

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

[0010] The transmission mechanism includes pulleys and a lifting belt, and the pulleys are provided on the top of the guide frame and on the piston rod of the hydraulic cylinder;

[0011] One end of the lifting belt is fixed to the top of the lifting frame, and the other end passes in sequence around the pulley at the top of the guide frame and the pulley on the piston rod of the hydraulic cylinder before being fixed to the guide frame;

[0012] When the piston rod of the hydraulic cylinder is retracted by the pump station, the lifting belt exerts an upward pulling force on the lifting frame, causing the lifting frame to move upward along the height direction of the guide frame, thereby lifting the emergency repair pier upward.

[0013] Furthermore, the guide frame and the lifting frame are in sliding or rolling engagement.

[0014] Furthermore, at least two of the aforementioned transmission mechanisms and two hydraulic cylinders connected to the transmission mechanisms are symmetrically arranged.

[0015] Furthermore, the base includes a cylinder base, a guide frame base, and a high pier base arranged around the cylinder base and the guide frame base;

[0016] The cylinder base is used to support the cylinder;

[0017] The guide frame base is used to support the guide frame;

Detailed Implementation

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] Reference Figures 1-5 A hydraulic lifting system for a repair pier includes 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 fixed on the pre-set foundation 14 and serves as a support; the bottom of the guide frame 2 is fixedly connected to the base 1; the lifting frame 3 is fitted around the guide frame 2, and the height of the lifting frame 3 is less than the height of the guide frame 2. The lifting frame 3 is used to lift the emergency repair pier 13; the hydraulic system is set on the base 1, and the hydraulic system includes a cylinder 11 and a pump station 12. The piston rod of the cylinder 11 is vertically upward; the transmission mechanism includes a pulley 9 and a lifting belt 10; pulleys 9 are provided on the top of the guide frame 2 and on 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 passes through the pulley 9 on the top of the guide frame 3 (as a fixed pulley) and the pulley 9 on the piston rod of the cylinder 11 (as a movable pulley) in sequence before being fixed to the guide frame 2; when the pump station 12 controls the piston rod of the cylinder 11 to retract, the lifting belt 10 forms an upward pulling force on the lifting frame 3, causing the lifting frame 3 to move upward along the height direction of the guide frame 2, thus lifting the emergency repair pier 13 upward.

[0039] Thus, 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 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. It does not require long-term assistance from large mechanical equipment, greatly reduces the labor intensity of the erection personnel, and can complete the erection of the emergency repair pier 13 in a short time to quickly restore traffic. It reduces the need for professional operators and improves 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 for the emergency repair pier 13. In particular, in this embodiment, a total of four transmission mechanisms and four hydraulic cylinders 11 are provided, symmetrically distributed along the four corners of the hydraulic lifting system of the emergency repair pier.

[0041] Specifically, the guide frame 2 and the lifting frame 3 can be engaged by sliding with a slider or by rolling with a roller, which facilitates the lifting movement of the lifting frame 3.

[0042] Specifically, exhibitors 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 known as an emergency repair pier base) arranged around 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; and the high pier base 8 is used to support the emergency repair pier 13 after it has been lifted.

[0043] More specifically, in this embodiment, both the guide frame 2 and the lifting frame 3 are modularly assembled space truss structures, which gives the hydraulic lifting system of the emergency repair pier advantages such as easy disassembly and assembly, strong interchangeability, and reusability.

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

[0045] Reference Figure 5 The high pier base 8 is fixed to the preset foundation 14. The guide frame 2 is fixed to the preset foundation 14 via the guide frame base 7, and the hydraulic cylinder 11 is fixed to the preset foundation 14 via the hydraulic cylinder base 6. Pulleys 9 are arranged on the top of the guide frame 2 and on the piston rod of the hydraulic cylinder 11. One end of the lifting belt 10 is fixed to the top of the lifting frame 3, and the other end passes sequentially around the pulley 9 on the top of the guide frame 2 and the pulley 9 on the piston rod of the hydraulic cylinder 11 before being fixed to the guide frame 2. When the pump station 12 controls the piston rod of the hydraulic cylinder 11 to retract, the lifting belt 10 exerts an upward pulling force on the lifting frame 3, causing the lifting frame 3 to move upward along the height direction of the guide frame 2, thus lifting 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 hydraulic cylinder 11 can be extended upward by the pump station 12 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 multi-section, detachable and splicable structure. Lifting is done in a step-by-step manner, lifting one section at a time. After lifting the previous section, the next section is manually hung (or connected) to the lower end of the previous section. As the previous section is lifted, the newly connected section is also in place. Initially, the cap beam 15 is located outside the guide frame 2 when lifted along with the lifting frame 3 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 uses a climbing frame (which can be located inside the guide frame 2, which has a spatial truss structure) to climb to the height of the cap beam 15, moves the cap beam 15 to the middle of the guide frame 2, and connects both ends of the cap beam 15 to the emergency repair pier. Then, lifting continues to a higher set height. After lifting is complete, the bottom support of the lowermost emergency repair pier section is fixed to the high pier base 8.

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