Abstract
Description
Technical Field
[0001] This application relates to the field of bridge engineering technology, and in particular to a beam lifting device. Background Technology
[0002] Bridge bearings bear the weight of the bridge structure and vehicle loads over a long period of time, and are also affected by the natural environment, such as temperature changes, humidity, and acid rain. As a result, they gradually age, and rubber bearings may harden, crack, and lose elasticity, thus failing to effectively perform their buffering and shock absorption functions and affecting the normal use of the bridge. When replacing bearings, jacks need to be placed on the pier top or at appropriate locations on the bridge structure. The number and location of the jacks should be reasonably determined according to the weight and structural form of the bridge structure to ensure that the force is evenly distributed when the bridge structure is lifted. Then, the jacks are controlled by an oil pump to lift the bridge structure synchronously.
[0003] Furthermore, existing patent publication number CN213925817U discloses a bridge reconstruction lifting structure. This device primarily uses connecting rods to fix connecting plates, and jacks are placed on the connecting plates to lift the beam. However, in actual use, it has the following shortcomings:
[0004] Firstly, the mass of the beam is too large. When the jacks lift the beam, the entire force of the beam will be applied to the connecting plate, and the supporting strength of the connecting rod is insufficient. Secondly, the traditional method is to arrange multiple jacks on the pier top and lift the beam through the cooperation of multiple jacks. However, due to space limitations, only small-sized jacks with low load-bearing capacity can be used. Therefore, many jacks need to be arranged around the pier top. This not only affects the subsequent replacement of the bearings, but also the fact that so many jacks do not produce a parallel effect. When one of them fails, it is easy to cause uneven stress in a local area. Therefore, this solution proposes a beam lifting device. Utility Model Content

[0040] This application discloses a beam lifting device.
[0041] Reference Figure 1 , Figure 3 , Figure 4As shown, a beam lifting device includes a support assembly 1, which is fixedly installed in grooves on both sides of a bridge pier. The support assembly 1 includes a first horizontal plate 106, which is horizontally installed in the groove in the middle of the top of the bridge pier.

Then, the insert plate 103 located on one side of the support plate 101 is aligned with the insertion hole 1060 at the end of the first horizontal plate 106.

The lifting assembly 2 includes multiple hydraulic telescopic cylinders 202 horizontally placed on the top of the support plate 101. The bottom of two hydraulic telescopic cylinders 202 abuts against a first pad 201. The first pad 201 is horizontally placed on both sides of the top of the support plate 101. The telescopic ends of the two hydraulic telescopic cylinders 202 abut against reinforcing steel plates 203. The top surfaces of both ends of the reinforcing steel plates 203 are symmetrically provided with connecting grooves 2030 that are perpendicular to each other. The inner surfaces of both ends of one reinforcing steel plate 203 are symmetrically provided with connecting columns 204 on both sides of the connecting groove 2030. The inner surfaces of both ends of the other reinforcing steel plate 203 are provided with connecting columns 204.

Then, the first pads 201 are placed horizontally on both sides of the top of the support plate 101. Next, the matching hydraulic telescopic cylinders 202 are placed on top of the first pads 201. Then, the reinforcing steel plates 203 are assembled together so that the connecting column 204 is inserted into the positioning hole 205. Then, the fixing plate 206 is snapped into the connecting groove 2030. Then, the assembled reinforcing steel plates 203 are placed at the telescopic ends of the top of the two hydraulic telescopic cylinders 202. Finally, the second horizontal plate 207 is inserted into the first connecting hole 2032 in the reinforcing steel plate 203. Finally, the components on the other side are installed according to the above steps, thus completing part of the installation of the lifting component 2.
[0046] It should be noted that the reinforcing steel plate 203, connecting column 204, fixing plate 206, and second horizontal plate 207 are all made of metal, while the first pad plate 201 is made of wood. The hydraulic telescopic cylinder 202 is a double-acting hydraulic cylinder for bridge lifting produced by Yangzhou Angli Electric Co., Ltd. The hydraulic telescopic cylinder 202 requires an external electric pump station. One electric pump station can provide power for multiple hydraulic jacks. The electric pump station is a ZB63 high-pressure electric pump produced by Shanghai Yili Machinery Equipment Co., Ltd.
[0047] When the electric pump station is connected to an external power source, the control circuit is immediately energized. Various control signal sources, such as push-button switches and remote control modules, send control signals to the motor controller. Based on the received signals, the motor controller, with the help of the driver, precisely regulates the motor's operating state, completing the motor's start, stop, and forward / reverse operations. Changes in the motor's operating state drive the oil pump to start or stop accordingly, thereby controlling the hydraulic oil pumping process. The pumped hydraulic oil is delivered to the hydraulic telescopic cylinder 202, driving its piston rod to extend or retract. Throughout the entire working process, the pressure sensor monitors the system pressure in real time and converts the pressure signal into an electrical signal, feeding it back to the motor controller. The motor controller dynamically adjusts the motor's operating state based on the preset pressure value and the feedback pressure signal to maintain stable system pressure. The power supply, motor controller, driver, pressure sensor, and the electrical control logic built between them involved in the electric pump station are all existing mature technologies. Therefore, the specific connection relationships will not be elaborated in detail. They can be applied according to the existing connection and assembly methods to ensure the stable coordinated operation of the electric pump station and the hydraulic telescopic cylinder 202.

A stud adapted to the threaded groove 2022 is provided at the middle of the bottom end of the lifting head 2023. The top of the lifting head 2023 abuts against the fourth horizontal plate 2024.
[0049] First, the required hydraulic telescopic cylinders 202, lifting heads 2023, and fourth horizontal plates 2024 are lifted to one side of the support plate 101 using a lifting device. Then, the two hydraulic telescopic cylinders 202 are placed horizontally at the top center of the support plate 101. At the same time, the top of the first connecting plate 2021 at the top of the hydraulic telescopic cylinders 202 is attached to the bottom surface of the reinforcing steel plate 203. Then, the bottom of the lifting head 2023 passes through the rectangular groove 208 in the middle of the reinforcing steel plate 203 and is threaded to the threaded groove 2022 at the top of the first connecting plate 2021, thereby fixing the lifting head 2023, the reinforcing steel plate 203, and the first connecting plate 2021 together. Meanwhile, the bottom surface of the middle part of the lifting head 2023 is attached to the top surface of the reinforcing steel plate 203. Finally, the fourth horizontal plate 2024 is placed on top of the lifting head 2023 to increase the contact area between the lifting head 2023 and the bridge and improve the stability of the lifting.
