Description

Technical Field

[0001] This invention relates to the field of bridge safety, and in particular to a hydraulic electromagnetic correction device for sloping bridges. Background Technology

[0002] Sloping bridges are typically installed on longitudinal slopes of roads or connecting road surfaces to urban overpasses, and are widely used in municipal bridges. Over long-term service, sloping bridges may slide downhill along the longitudinal slope. The main reasons for this sliding are: firstly, the increasing number of heavy-duty vehicles and the prevalence of overloading; secondly, insufficient research on the design and construction of sloping bridges, especially regarding their dynamic mechanisms, leading to improper bearing placement in some cases; and thirdly, the influence of temperature loads and the bridge's own weight can also cause slippage. Therefore, to control and correct the slippage of sloping bridges, extend their service life, and reduce maintenance costs, a sloping bridge correction device is urgently needed. Summary of the Invention

[0003] The present invention aims to provide a hydraulic electromagnetic correction device for sloping bridges, which solves the problem of beam slippage that occurs in existing sloping bridges during long-term service.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: A hydraulic electromagnetic correction device for a sloping bridge includes a first hydraulic rod disposed on the bridge body and a hydraulic cavity disposed on a bridge abutment on the corresponding side of the bridge body. The first hydraulic rod is provided with a piston that is slidably and sealingly connected to the hydraulic cavity. The hydraulic cavity is filled with hydraulic oil. A piston and a second hydraulic rod connected to the piston are slidably and sealingly connected to one end of the hydraulic cavity away from the first hydraulic rod. The second hydraulic rod and the first hydraulic rod are respectively located on both sides of the support column of the sloping bridge body. A reset mechanism is provided on the second hydraulic rod. The reset mechanism includes a power supply, a first electromagnet, a second electromagnet, a conductive rod, a resistance wire, and a control switch. The power supply is disposed on the bridge abutment. The first electromagnet is disposed on the edge of the bridge abutment and is electrically connected to the power supply. The second electromagnet is disposed on the edge of the sloping bridge body. The conductive rod is connected to the free end of the second hydraulic rod and is electrically connected to the second electromagnet. The conductive rod is slidably connected to the resistance wire, which is disposed on the support column of the sloping bridge body. The control switch is electrically connected to the power supply.

[0005] Furthermore, the bridge body of the slope is provided with a cavity, one end of the first hydraulic rod is slidably connected in the cavity, the first hydraulic rod is provided with a second magnet located in the cavity, and the cavity is provided with a first magnet that repels the second magnet.

[0006] By using the above configuration, the mutual repulsion between the first and second magnets is utilized to prevent the reset mechanism from over-resetting the ramp bridge, which helps maintain the stability of the ramp bridge.

[0007] Furthermore, the control switch is a displacement switch, and the control switch is mounted on the beam.

[0008] With the above settings, when the ramp bridge deviates, it causes the first and second electromagnets to move closer to each other, and the power supply is turned on by a control switch. Furthermore, as the displacement of the ramp bridge increases, the current can be increased by reducing the resistance, thereby increasing the magnetic force between the first and second electromagnets, which is more conducive to realizing the intelligent correction and reset of the ramp bridge.

[0009] Furthermore, the end of the first hydraulic rod located inside the cavity, the first magnet, and the second magnet are all arc-shaped.

[0010] Furthermore, the first hydraulic rod has a groove, and the first magnet is slidably connected in the groove.

[0011] The above settings can limit the movement of the first hydraulic rod and ensure that the magnetic forces of the first and second magnets act entirely in the direction of movement of the first hydraulic rod.

[0012] Compared with existing technologies, the beneficial effects of this solution are:

[0013] This solution can intelligently adjust the correction magnetic force according to the displacement of the sloping bridge, which helps to improve the correction effect of the sloping bridge. At the same time, the first magnet and the second magnet realize the first-level correction, while the first electromagnet and the second electromagnet realize the second-level correction. The two-level correction structure ensures the displacement of the sloping bridge and extends the service life of the sloping bridge. Attached Figure Description

[0014] Figure 1 This is a front view of a hydraulic electromagnetic correction device for a sloping bridge according to the present invention. Detailed Implementation

[0015] The present invention will be further described in detail below through specific embodiments:

[0016] The reference numerals in the accompanying drawings include: beam 1, hydraulic chamber 2, first hydraulic rod 3, first magnet 4, second magnet 5, hydraulic oil 6, second hydraulic rod 7, power supply 8, first electromagnet 9, second electromagnet 10, conductive rod 11, resistance wire 12, control switch 13, and bridge abutment 14.

[0017] Example

[0018] As attached Figure 1 As shown in this embodiment, because the long-serving ramp bridge body 1 slides along the longitudinal direction of the bridge (sliding to the right in the figure, but in actual engineering, the ramp bridge slides to the lower right), both the limiting device and the ramp bridge as a whole have an inclination angle. For ease of demonstration, Figure 1The limiting device and the ramp bridge were adjusted to be horizontal.

[0019] A hydraulic-electromagnetic correction device for a sloping bridge includes a cavity disposed on the bridge body 1 and a hydraulic chamber 2 disposed on the corresponding side abutment 14 of the bridge body 1. In this embodiment, the cavity extends through the right side of the sloping bridge, and a first hydraulic rod 3 is disposed within the cavity. The left end of the first hydraulic rod 3 has a semi-circular structure and is slidably connected to the cavity. Two opposing fixing blocks are fixedly connected to the opening of the cavity, covering the first hydraulic rod. The two fixing blocks are connected together by bolts, and a first magnet 4 is attached to the left side of each fixing block. A second magnet 5, which repels the first magnet 4, is attached to the right side of the semi-circular structure of the first hydraulic rod 3. The shapes of the first magnet 4 and the second magnet 5 are both arc-shaped, the same as the upper semi-circular structure of the first hydraulic rod 3. Sliding grooves are opened on both the upper and lower sides of the first hydraulic rod 3, and each first magnet 4 is slidably connected in the corresponding sliding groove. The sliding grooves help maintain the stability of the first hydraulic rod 3 during sliding. The right end of the first hydraulic rod 3 is provided with a piston that is slidably and sealed to the hydraulic chamber 2. The hydraulic chamber 2 is filled with hydraulic oil 6. The end of the hydraulic chamber 2 away from the first hydraulic rod 3 is slidably and sealed to the piston and the second hydraulic rod 7 connected to the piston. The second hydraulic rod 7 and the first hydraulic rod 3 are located on both sides of the support of the slope bridge body.

[0020] The second hydraulic rod 7 is equipped with a reset mechanism, which includes a power supply 8, a first electromagnet 9, a second electromagnet 10, a conductive rod 11, a resistance wire 12, and a control switch 13. The power supply 8 is located on the bridge abutment 14. The first electromagnet 9 is located at the edge of the bridge abutment 14 and is electrically connected to the power supply 8. The second electromagnet 10 is located at the edge of the beam 1, and the first and second electromagnets 9 and 10 are positioned opposite each other. When energized, the first and second electromagnets 9 and 10 generate a repulsive magnetic force. The conductive rod 11 is connected to the free end of the second hydraulic rod 7 and is electrically connected to the second electromagnet 10. The conductive rod 11 is slidably connected to the resistance wire 12, and during sliding, the conductive rod 11 remains in contact with the resistance wire 12. The resistance wire 12 is mounted on the support pillar of the sloping bridge and is covered by a protective box embedded in the support pillar. The control switch 13 is electrically connected to the power supply 8 and is a displacement switch located on the beam 1.

[0021] The working process of this plan:

[0022] In the initial state, the bridge body 1 of the ramp did not shift. At this time, no magnetic force was generated between the first magnet 4 and the second magnet 5. Although the conductive rod 11 was in contact with the resistance wire 12, the control switch 13 did not turn on the power supply 8 because the displacement of the ramp was 0, so the first electromagnet 9 and the second electromagnet 10 did not generate magnetic force.

[0023] When the bridge body 1 begins to deviate and reaches the designed deviation, the control switch 13 turns on the power supply 8. At this time, the first electromagnet 9 and the second electromagnet 10 are energized, generating a repulsive force. This repulsive force pushes the bridge body 1 to gradually return to its original position. During the process of the bridge body 1 moving to the left to return to its original position, the conductive rod 11 moves to the left along with the bridge body 1. At this time, the resistance provided by the resistance wire 12 in the system consisting of the conductive rod 11, the power supply 8, the first electromagnet 9, the second electromagnet 10, and the connecting wires increases, thereby reducing the current in the system. This causes the repulsive force generated by the first electromagnet 9 and the second electromagnet 10 to gradually decrease, avoiding the problem of excessive repulsive force causing the bridge body 1 to return to its original position due to over-reset. After the bridge body 1 moves, the conductive rod 11 drives the second hydraulic rod 7 to move, thereby using the hydraulic oil in the hydraulic chamber 2 to slow down the movement speed of the bridge body 1.

[0024] During the movement of beam 1, the first magnet 4 and the second magnet 5 inside the cavity will further slow down the movement of beam 1 through their mutual repulsion, effectively avoiding the problem of safety of the sloping bridge operation caused by the excessive movement of beam 1. At the same time, it also further avoids the problem of beam 1 resetting due to excessive repulsive force generated by the first electromagnet 9 and the second electromagnet 10, effectively maintaining the safety of the sloping bridge beam 1 in correcting its deviation.

[0025] This solution achieves intelligent adjustment of the magnetic force required for resetting beam 1 through a reset mechanism, and dynamically adjusts the force by means of the opposing repulsive force generated by the first magnet 4 and the second magnet 5 in the cavity (the repulsive force changes dynamically with the distance between them), effectively avoiding overcorrection.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention.
