Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge construction equipment technology, specifically to a bridge jacking and heightening construction device. Background Technology
[0002] With increasing traffic demand and adjustments to urban planning, many existing bridges need to be heightened and upgraded to meet new traffic requirements.
[0003] Chinese Patent Application No. 2021215310311 discloses a bridge translation and lifting device, belonging to the field of bridge reconstruction technology. This device includes a bridge body, with at least two sets of lifting mechanisms at the bottom. Each set of lifting mechanisms has a connector at its top that connects to the bridge body, and a support block at its bottom. The support block has a sliding plate at its bottom that drives the block to slide. This bridge translation and lifting device, by installing at least two of these devices at the bottom of the bridge body, lifts the bridge body to a certain height. The devices then alternately lift and move forward, thereby moving the bridge body. By lifting the bridge body and then using jacks to push it forward, the device achieves the goal of relocating the original bridge to a planned location without demolishing and rebuilding it, through a combination of translation and lifting.
[0004] However, the above-mentioned technical solutions can only lift and move the bridge, but cannot rotate it, making it inconvenient to move the bridge to the planned location. Utility Model Content
[0005] The main purpose of this utility model is to provide a bridge jacking and heightening construction device to solve the above-mentioned technical problems.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a bridge jacking and heightening construction device, comprising a base, a controller inside the base, a support rod on the base, a first support on the top of the support rod, a second support on the top of the first support, a bridge adjustment structure on the second support; and a rotating structure between the first support and the second support.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the bridge adjustment structure includes a turntable, a track on the turntable, a sliding support block inside the track, and a plurality of first jacks on the sliding support block.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a second jack is provided on one side of the sliding support block.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the rotating structure includes a first pulley and a second pulley, the first pulley is provided with a rotating shaft, one end of the rotating shaft is rotatably connected to the turntable; the bottom of the second pulley is provided with a drive motor; and a transmission belt is provided between the first pulley and the second pulley.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the first jack is equipped with a pressure sensor and a displacement sensor, both of which are electrically connected to the controller.
[0011] The beneficial effects of this utility model are as follows: The bridge adjustment structure of this utility model adopts a turntable and track design, and the sliding support block can slide in the track. With the first jack, the support position and height of the bridge can be flexibly adjusted to adapt to the construction needs of different bridges. The rotating structure adopts a pulley and transmission belt design. Driven by a drive motor, the turntable can be rotated flexibly, which facilitates the adjustment of the support angle of the bridge. Attached Figure Description

[0016] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0017] See attached diagram. Figures 1 to 2 The bridge lifting and raising construction device in this embodiment includes a base 1, a controller inside the base 1, a support rod 2 on the base 1, a first support 3 on the top of the support rod 2, a second support 4 on the top of the first support 3, a bridge adjustment structure on the second support 4, and a rotating structure between the first support 3 and the second support 4.
[0018] Furthermore, the bridge adjustment structure includes a turntable 5, on which a track 50 is mounted. A sliding support block 51 is mounted within the track 50, and several first jacks 6 are mounted on the sliding support block 51. A second jack 7 is mounted on one side of the sliding support block 51. The second jacks 7 can drive the sliding support block 51 to slide within the track 50. In conjunction with the first jacks 6, the support position and height of the bridge can be flexibly adjusted to adapt to the construction needs of different bridges.
[0019] Furthermore, the rotating structure includes a first pulley 8 and a second pulley 9. The first pulley 8 has a rotating shaft 80, one end of which is rotatably connected to the turntable 5. The bottom of the second pulley 9 has a drive motor 90. A transmission belt 81 connects the first pulley 8 and the second pulley 9. This rotating structure, using pulleys and a transmission belt 81, and driven by the drive motor 90, enables flexible rotation of the turntable 5, facilitating adjustment of the bridge's support angle and adapting to construction needs in different directions.
[0020] Furthermore, the first jack 6 is equipped with a pressure sensor and a displacement sensor, both of which are electrically connected to the controller. Through real-time monitoring by the sensors, the controller can issue an early warning signal when the lifting force or displacement exceeds the safe range, allowing for timely adjustment of construction parameters and preventing construction accidents. The pressure and displacement sensors on the first jack can monitor the lifting force and displacement of the jack in real time, providing real-time data support for the construction process.
