Description

Technical Field

[0001] The invention belongs to the technical field of bridge manufacturing, and in particular relates to a vertical lifting opening bridge. Background Art

[0002] A bascule bridge refers to a bridge whose span structure can be moved or rotated. Conventional bascule bridges for vehicles mainly include vertical swing bridges, horizontal swing bridges and vertical lift bridges. With the deepening of urbanization in my country, some construction sites are limited by existing elevations or have needs such as flood control and navigation, making it difficult to build conventional bridges, and it is necessary to build bascule bridges that can be lifted vertically. Conventional vertical lift bascule bridges require huge bridge towers at the four corners of the bridge to meet the needs of counterweight placement and beam locking after the bridge is opened. Its structure is complex, it occupies a large area, and its application range is narrow, making it difficult to adapt to the needs of intensive urban land construction. Summary of the invention

[0003] In view of this, an object of the present invention is to provide a vertical lifting opening bridge to solve the deficiencies in the prior art.

[0004] In order to achieve the above object, the present invention is achieved through the following technical solutions:

[0005] A vertical lifting opening bridge is provided, which includes a main beam, an abutment, a support, a pile foundation, a pile leg and a lifting device. The abutment is supported on a foundation through the pile foundation, the support is arranged on the top surface of the abutment, the main beam is parked on the support, the pile leg is erected on the top of the abutment and the bottom end of the pile leg is pre-buried in the abutment, the lifting device is slidably mounted on the pile leg, and both ends of the main beam are fixedly connected to the lifting device. The lifting device can be vertically lifted and lowered along the pile leg to drive the main beam to be vertically lifted and lowered.

[0006] As described in the vertical lifting opening bridge, wherein the pile legs are provided with pin holes at intervals along the height direction, the lifting device comprises a movable ring beam, a fixed ring beam, a lifting assembly, a movable ring beam latch assembly and a fixed ring beam latch assembly, the fixed ring beam and the movable ring beam are sequentially slidably sleeved on the pile legs from bottom to top, the lifting assembly is arranged between the movable ring beam and the fixed ring beam, the upper and lower ends of the lifting assembly are respectively fixedly connected to the movable ring beam and the fixed ring beam, and the movable ring beam latch assembly is circumferentially arranged on the peripheral side surface of the movable ring beam, The fixed ring beam latch assembly is circumferentially arranged on the circumferential side surface of the fixed ring beam; the dynamic ring beam and the fixed ring beam are respectively inserted and pulled out of the pin holes through the dynamic ring beam latch assembly and the fixed ring beam latch assembly, so as to realize the locking and separation of the dynamic ring beam, the fixed ring beam and the pile legs; the lifting assembly drives the dynamic ring beam and the fixed ring beam to perform vertical lifting and lowering along the pile legs, and cooperates with the locking and separation of the dynamic ring beam, the fixed ring beam and the pile legs, so as to realize that the lifting device drives the main beam to be lifted and lowered in the vertical direction.

[0007] As described in the vertical lifting opening bridge, wherein the lifting assembly also includes a controller and a sensor, wherein the controller is responsible for controlling the lifting and the insertion and extraction of the movable ring beam latch assembly and the fixed ring beam latch assembly in the pin hole, and the sensor detects the displacement of the lifting assembly, thereby determining the relative positions of the movable ring beam latch assembly, the fixed ring beam latch assembly and the pin hole during the lifting process.

[0008] As described in the vertical lifting opening bridge, wherein the lifting assembly adopts a large-stroke hydraulic cylinder with large-spacing pin holes, or adopts a small-stroke hydraulic cylinder with small-spacing pin holes.

[0009] As described in the vertical lifting opening bridge, wherein the main beam and the pile legs are both made of steel structure.

[0010] The beneficial effects of the technical solution of the present invention are:

[0011] 1. It avoids the disadvantages of conventional vertical lifting bascule bridges that require huge bridge towers and complex structures. It only requires small pile legs and lifting devices. It has a simple structure and small footprint. It can be used in construction conditions with limited sites and has a wide range of applications.

[0012] 2. The lifting mode can be set according to the opening requirements of the opening bridge and local conditions to save construction costs. A large-stroke hydraulic cylinder with large-pitch pin holes can be used to quickly lift it into place at one time, or a small-stroke hydraulic cylinder with small-pitch pin holes can be used to gradually lift it into place;

[0013] 3. The lifting components in the lifting device adopt the working mode of hydraulic cylinder under tension, which can avoid the stability problem of the pressure rod when the cylinder is under pressure, so as to reduce the size and cost of the cylinder, and change the unfavorable working environment of the cylinder under pressure into a favorable working environment under tension, which can increase the service life of the cylinder and reduce the maintenance cost.

[0024] The use of "including," "having," and "comprising" and variations thereof herein is meant to encompass the items listed thereafter and their equivalents and additional items. Although reference may be made to directions such as above, below, upward, downward, rearward, bottom, top, front, rear, etc., in describing the drawings, for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the present invention in any form. In addition, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0025] See also Figure 1 , Figure 2 and Figure 3As shown, the vertical lifting bascule bridge of the present invention comprises a main beam 1, an abutment 2, a support 3, a pile foundation 4, a pile leg 5 and a lifting device 6. The abutment 2 is supported on the foundation through the pile foundation 4. The abutment 2 transmits the action to the foundation through the pile foundation 4. The support 3 is arranged on the top surface of the abutment 2. The main beam 1 is parked on the support 3. The pile leg 5 is erected on the top of the abutment 2 and the bottom end of the pile leg 5 is pre-buried in the abutment 2. The lifting device 6 is slidably sleeved on the pile leg 5. The two ends of the main beam 1 are fixedly connected to the lifting device 6. The lifting device 6 can be vertically lifted and lowered along the pile leg 5 to drive the main beam 1 to lift and lower vertically. The pile leg 5 can also be slidably penetrated in the structure of the main beam 1 to minimize the occupation of vertical and horizontal space. The lower part of the pile leg 5 pre-buried 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 is provided with pin holes 51 at intervals along the height direction, preferably at equal intervals, and the lifting device 6 includes a movable ring beam 61, a fixed ring beam 62, a lifting assembly 63, a movable ring beam latch assembly 64 and a fixed ring beam latch assembly 65, and the fixed ring beam 62 and the movable ring beam 61 are sequentially slidably sleeved on the pile leg 5 from bottom to top. The lifting assembly 63 is arranged between the movable ring beam 61 and the fixed ring beam 62, and the upper and lower ends of the lifting assembly 63 are respectively hinged to the movable ring beam 61 and the fixed ring beam 62, the movable ring beam latch assembly 64 is circumferentially arranged on the peripheral side of the movable ring beam 61, and the fixed ring beam latch assembly 65 is circumferentially arranged on the peripheral side of the fixed ring beam 62. The dynamic ring beam 61 and the fixed ring beam 62 are respectively inserted and pulled out of the pin hole 51 through the dynamic ring beam latch assembly 64 and the fixed ring beam latch assembly 65, so as to realize the locking and separation of the dynamic ring beam 61, the fixed ring beam 62 and the pile leg 5. The lifting assembly 63 drives the dynamic ring beam 61 and the fixed ring beam 62 to be vertically lifted and lowered along the pile leg 5, and cooperates with the locking and separation of the dynamic ring beam 61, the fixed ring beam 62 and the pile leg 5 to realize the lifting device 6 driving the main beam 1 to be lifted and lowered in the vertical direction.

[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 extraction of the movable 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 movable 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 large-spacing pin holes 51, or a small-stroke hydraulic cylinder with small-spacing pin holes 51. The hydraulic cylinder is pulled to avoid the stability problem of the pressure rod when the cylinder is compressed, thereby reducing the size and cost of the cylinder.

[0029] The main beam 1 and the pile legs 5 are both made of steel structures, and the beam end of the main beam 1 can be provided with an overhanging structure to facilitate fixed connection with the lifting device 6.

[0030] Continuing to refer to the diagram, when the bridge needs to be opened, the controller controls the dynamic ring beam pin assembly 64 to be pulled out from the corresponding pin hole 51 to unlock the dynamic ring beam 61 and the pile leg 5. When the sensor detects that the dynamic ring beam 61 and the pile leg 5 are unlocked, the controller controls the dynamic ring beam 61 to move vertically upward along the pile leg 5 under the action of the lifting assembly 63. When the dynamic ring beam latch assembly 64 is aligned with the upper pin hole 51, the sensor detects that the dynamic ring beam 61 has reached the specified position, the controller stops the movement of the lifting assembly 63, and inserts the dynamic ring beam latch assembly 64 into the upper pin hole 51 to complete the locking of the dynamic ring beam 61 and the pile leg 5; after the sensor detects that the dynamic ring beam 61 and the pile leg 5 are locked, the controller controls the fixed ring beam latch assembly 65 to be pulled out from the corresponding pin hole 51 to complete the unlocking of the fixed ring beam 62 and the pile leg 5. After 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 move the main beam 1 upward. When the fixed ring beam latch assembly 65 is aligned with the upper pin hole 51, the sensor detects that the fixed ring beam 62 has reached the specified position, the controller stops the movement of the lifting assembly 63, and inserts the fixed ring beam latch assembly 65 into the upper pin hole 51 to complete the locking of the fixed ring beam 62 and the pile leg 5, so that the main beam 1 can be vertically raised by one level and locked at that level. Repeating the above steps can realize the gradual rise of the main beam 1 until it reaches the specified position; when the bridge needs to be closed, repeating the above steps in reverse can realize the gradual descent of the main beam 1 until it reaches the specified position. For a bascule bridge with a small stroke, a lifting assembly 63 with a large stroke is used, and the above steps can be used to achieve one-time lifting to the designated position.

[0031] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
