Furthermore, terms such as first, second, third, etc., are used herein for purposes of explanation only and are not intended to convey or imply importance or significance.

[0025] Referring to Figure 1 , Figure 2 and Figure 3As shown, this utility model of a vertical lifting and opening bridge includes a main beam 1, abutment 2, support 3, pile foundation 4, pile leg 5, and lifting device 6. The abutment 2 is supported on the foundation by the pile foundation 4, and the abutment 2 transmits the load to the foundation through the pile foundation 4. The support 3 is located on the top surface of the abutment 2, and the main beam 1 rests on the support 3. The pile leg 5 stands upright on the top of the abutment 2, and the bottom end of the pile leg 5 is embedded in the abutment 2. The lifting device 6 is slidably sleeved on the pile leg 5. The lifting device 6 is fixedly connected to both ends of the main beam 1. The lifting device 6 can vertically lift and lower along the pile leg 5, thereby driving the main beam 1 to vertically lift and lower. The pile leg 5 can also slide through the structure of the main beam 1 to minimize the occupation of vertical and horizontal space. The lower part of the pile leg 5 embedded in the abutment 2 can be provided with pile feet as needed.

[0026] In a preferred embodiment, see Figure 4 , Figure 5 and Figure 6 As shown, the pile leg 5 has pin holes 51 spaced apart along its height direction, preferably evenly spaced. The lifting device 6 includes a moving ring beam 61, a fixed ring beam 62, a lifting assembly 63, a moving ring beam pin assembly 64, and a fixed ring beam pin assembly 65. The fixed ring beam 62 and the moving ring beam 61 are slidably mounted on the pile leg 5 from bottom to top. The lifting assembly 63 is located between the moving ring beam 61 and the fixed ring beam 62. The upper and lower ends of the lifting assembly 63 are hinged to the moving ring beam 61 and the fixed ring beam 62, respectively. The moving ring beam pin assembly 64 is circumferentially located on the circumferential side of the moving ring beam 61, and the fixed ring beam pin assembly 65 is circumferentially located on the circumferential side of the fixed ring beam 62. The moving ring beam 61 and the fixed ring beam 62 are respectively inserted into the pin hole 51 through the moving ring beam pin assembly 64 and the fixed ring beam pin assembly 65, so as to lock and separate the moving ring beam 61, the fixed ring beam 62 and the pile leg 5. The lifting assembly 63 drives the moving ring beam 61 and the fixed ring beam 62 to move vertically along the pile leg 5. With the locking and separation of the moving ring beam 61, the fixed ring beam 62 and the pile leg 5, the lifting device 6 drives the main beam 1 to move vertically.

[0027] Furthermore, the lifting assembly 63 also includes a controller and a sensor. The controller is responsible for controlling the lifting and the insertion and removal actions of the moving ring beam pin assembly 64 and the fixed ring beam pin assembly 65 in the pin hole 51. The sensor detects the displacement of the lifting assembly 63, thereby determining the relative positions of the moving ring beam pin assembly 64, the fixed ring beam pin assembly 65 and the pin hole 51 during the lifting process.

[0028] Preferably, the lifting assembly 63 uses a large-stroke hydraulic cylinder with a large-pitch pin hole 51, or a small-stroke hydraulic cylinder with a small-pitch pin hole 51. The hydraulic cylinder is used in a tension-operated mode, which can avoid the stability problem of the pressure rod when the cylinder is compressed, thereby reducing the size and cost of the cylinder.

[0029] Both the main beam 1 and the pile leg 5 are made of steel. The beam end of the main beam 1 can be provided with an overhang structure to facilitate fixed connection with the lifting device 6.

[0030] Continuing to refer to the drawings, when the bridge needs to be opened, the controller controls the movable ring beam pin assembly 64 to be pulled out of the corresponding pin hole 51, so as to realize the unlocking of the movable ring beam 61 and the pile leg 5. When the sensor detects that the movable ring beam 61 and the pile leg 5 are unlocked, the controller controls the movable ring beam 61 to move vertically upward along the pile leg 5 under the action of the lifting assembly 63. When the movable ring beam pin assembly 64 is aligned with the upper pin hole 51, the sensor detects that the movable ring beam 61 reaches the specified position, the controller stops the movement of the lifting assembly 63, and the movable ring beam pin assembly 64 is inserted into the upper pin hole 51, so as to complete the locking of the movable ring beam 61 and the pile leg 5. When the sensor detects that the movable ring beam 61 and the pile leg 5 are locked, the controller controls the fixed ring beam pin assembly 65 to be pulled out of the corresponding pin hole 51, so as to complete the unlocking of the fixed ring beam 62 and the pile leg 5. When the sensor detects that the fixed ring beam 62 and the pile leg 5 are unlocked, the controller controls the lifting assembly 63 to drive the fixed ring beam 62 to move vertically upward, and the main beam 1 is moved upward. When the fixed ring beam pin assembly 65 is aligned with the upper pin hole 51, the sensor detects that the fixed ring beam 62 reaches the specified position, the controller stops the movement of the lifting assembly 63, and the fixed ring beam pin assembly 65 is inserted into the upper pin hole 51, so as to complete the locking of the fixed ring beam 62 and the pile leg 5, and realize the upward movement of the main beam 1 by one level. The above steps are repeated, so as to realize the progressive upward movement of the main beam 1 until reaching the specified position. When the bridge needs to be closed, the above steps are repeated in reverse, so as to realize the progressive downward movement of the main beam 1 until reaching the specified position. For an open bridge with a small stroke, a lifting assembly 63 with a large stroke is adopted, and the above steps are used, so as to realize one-time lifting to the position.

[0031] The above is only the preferred embodiment of the present application, and does not limit the implementation and protection scope of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious changes made according to the content of the present application can be included in the protection scope of the present application.
