Technical Field

[0001] The utility model relates to the technical field of bridge maintenance, in particular to a reverse pulling and back pushing device for rectifying the deviation of bridge piers. Background Art

[0002] A bridge refers to a structure erected over rivers, lakes, or the sea to enable vehicles and pedestrians to pass smoothly. Bridge piers are substructures that support the bridge span structure and transmit dead loads and vehicle live loads to the foundation. Abutments are located on both sides of the bridge. However, during the installation process or long-term use, the piers of the bridge are prone to longitudinal tilt, so the warping needs to be corrected.

[0003] At present, the conventional practice is to use a jack-type pushing device. However, the reaction platform of the pushing device has very high installation accuracy requirements, and it is difficult to install the jack-type pushing device tightly on the outside of the pier, which causes the installation deviation of the jack-type pushing device to be too large, thus affecting the correction effect of the pier. Utility Model Content

The back thrust is generated by the deviation correction component to push the cap beam, thereby driving the longitudinal deviation correction of the bridge piers. The deviation correction speed and correction amount of the bridge piers can be monitored by the monitoring component.

Two openings are opened on both sides of the top of the mounting plate, and four mounting holes are opened at the bottom of the box beam, and expansion bolts b are arranged inside the four openings. The correction component is used to correct the deviation of bridge piers.

[0007] Optionally, the monitoring component includes: a displacement sensor installed on one side of the outer end of the jack, an alarm housing installed on the top of the cross plate, an audible and visual alarm installed inside the alarm housing, sound transmission holes are opened on both sides of the outer end of the alarm housing, and a control panel is installed on the top of the cross plate, wherein the detection component is used to monitor the correction amount and correction speed of the pier.

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0019] The embodiment of the present application provides a back-pull and back-push device for correcting the deviation of bridge piers. The back-pull and back-push device for correcting the deviation of bridge piers can use the box beam as a reaction force fulcrum through the correction component to generate a back thrust to push the cap beam, thereby driving the longitudinal deviation of the bridge pier. The correction component can avoid the installation of a top-pushing reaction platform, reduce the difficulty of the correction construction, and improve the correction effect. The correction amount and correction speed of the bridge pier can be monitored through the monitoring component, and the sound and light alarm can be used to alert the staff to the excessive correction of the bridge pier. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0020] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] Example:

[0022] See also Figure 1-6 In this embodiment, a reverse pulling and pushing device for correcting the deviation of a bridge pier is provided, comprising: a box girder 1, a cap beam 101 arranged on one side of the bottom of the box girder 1, a pier 102 is arranged at the bottom of the cap beam 101, a cross plate 103 is arranged on one side of the outer end of the cap beam 101, a correction component arranged on one side of the outer end of the cap beam 101, which is used to correct the deviation of the pier 102; a monitoring component is arranged on the top of the cross plate 103, which is used to monitor the correction speed of the pier 102.

[0023] Among them, the correction component includes: a jack 2 installed on the top of the cross plate 103, a force transmission rod 201 arranged on one side of the outer end of the jack 2, a fixed block 202 installed on the outside of the force transmission rod 201, and a mounting plate 203 connected to the top of the fixed block 202. When correcting the deviation of the bridge pier, the jack 2 is started to contract the force transmission rod 201, so that the force transmission rod 201 moves toward the cap beam 101. However, since the force transmission rod 201 is connected to the box beam 1 through the fixed block 202 and the mounting plate 203, and the box beam 1 is fixed, when the force transmission rod 201 moves, it will drive the jack 2 to move toward the fixed block 202, and the jack 2 can push the cap beam 101 and the bridge pier 102 for longitudinal correction.

[0024] Among them, two openings 4 are provided on both sides of the top of the mounting plate 203, four mounting holes 401 are provided at the bottom of the box beam 1, and expansion bolts b402 are provided inside the four openings 4. When the force transmission rod 201 passes through the through hole and is located at the bottom of the box beam 1, the fixing block 202 can be installed on the outside of the force transmission rod 201, and the mounting plate 203 is located at the bottom of the box beam 1, and the four openings 4 are aligned with the four mounting holes 401, and then the expansion bolts b402 are transferred through the openings 4 into the mounting holes 401, so that the mounting plate 203 is fixedly installed at the bottom of the box beam 1, and one end of the force transmission rod 201 is fixed.

[0025] Among them, the monitoring component includes: a displacement sensor 5 installed on one side of the outer end of the jack 2, an alarm housing 501 installed on the top of the cross plate 103, and an audible and visual alarm 502 installed inside the alarm housing 501. When the pier 102 is corrected, the correction amount and correction speed of the pier 102 are monitored by the displacement sensor 5. When the displacement sensor 5 detects that the correction speed of the pier 102 is too fast, it can output a signal to the control panel and start the audible and visual alarm 502 through the control panel, so that the staff can discover it at the first time and stop correcting the pier 102.

[0026] Among them, a support plate 3 is installed on the outside of the jack 2, four through holes 301 are opened on one side of the outer end of the support plate 3, four fixing holes are opened on one side of the outer end of the cap beam 101, and expansion bolts a302 are arranged inside the four through holes 301. A through hole is opened on one side of the outer end of the cap beam 101, and one end of the force transmission rod 201 passes through the through hole and protrudes from the one side of the outer end of the cap beam 101. When the device is used, a through hole is opened on one side of the outer end of the cap beam 101, and multiple through holes are opened on one side of the outer end of the cap beam 101, and then one end of the force transmission rod 201 passes through the through hole to protrude from one side of the outer end of the cap beam 101 and extends to the bottom of the box beam 1, and then one side of the outer end of the support plate 3 is fitted with the cap beam 101, and the four fixing holes are aligned with the four through holes 301, and then one end of the expansion bolt a302 passes through the through hole 301 and is transferred into the fixing hole, thereby fixing the support plate 3 and the jack 2 to one side of the outer end of the cap beam 101.

[0027] The displacement sensor 5 is a LVTD type. The displacement sensor 5 uses a metal-sensitive linear device. When the power is turned on, an alternating magnetic field is generated on the sensing surface of the switch. When a metal object approaches the sensing surface, eddy currents are generated, thereby absorbing the energy of the oscillator, causing the amplitude of the oscillator output to decay linearly with distance. By analyzing the change in the attenuation, the position of the object can be detected without contact.

[0028] The model of the sound and light alarm 502 is LTD-1101J. The sound and light alarm 502 is mainly composed of a sound chip, a transistor, a transformer, a speaker and a timing circuit. These components work together to generate sound and light signals. The sound and light alarm uses the sound chip for amplification and drives the speaker to make a sound through the transistor and the transformer. This is usually the first stage reaction when the alarm is activated. The alarm is also equipped with an ultra-bright light emitting diode for emitting a flashing light signal. The response at this stage depends on the control of the timing circuit to ensure that the frequency and intensity of the light achieve a certain warning effect.

[0029] Among them, sound transmission holes 6 are provided on both sides of the outer end of the alarm housing 501, and a control panel is installed on the top of the horizontal plate 103, wherein the sound transmission hole 6 is used to ensure that the alarm sound emitted by the sound and light alarm 502 can pass through the alarm housing 501, wherein the top of the alarm housing 501 can be made of acrylic material, so that the top of the alarm housing 501 is light-transmissive, ensuring that the bright light emitted by the sound and light alarm 502 can penetrate the alarm housing 501, and the control panel is used to control the use of the jack 2, the displacement sensor 5 and the sound and light alarm 502, and the control panel can be used by remote control, so that the staff can start the jack 2 away from the pier to correct the pier, and the control panel, jack 2, displacement sensor 5 and sound and light alarm 502 are all powered by an external power supply, and the control program involved in the utility model can be implemented by those skilled in the art according to the same or similar principles in the prior art, and this part is not the innovation of the utility model.

[0030] Among them, the bottom side of the horizontal plate 103 is connected to the vertical plate 7, and a reinforcing plate 701 is arranged between the horizontal plate 103 and the vertical plate 7. Four circular holes 702 are opened on one side of the outer end of the vertical plate 7, and four bolt holes are opened on one side of the outer end of the cap beam 101. Expansion bolts c703 are arranged inside the four circular holes 702. When installing the jack 2, four bolt holes need to be opened on the outer end of the cap beam 101, and then the outer end of the vertical plate 7 is fitted with the cap beam 101, and the four bolts are fixed. The bolt hole is aligned with the circular hole 702, and then one end of the expansion bolt c703 is passed through the circular hole 702 and turned into the bolt hole, thereby fixing the vertical plate 7 and the horizontal plate 103 on one side of the outer end of the cap beam 101, so that the jack 2 can be located on the top of the horizontal plate 103, and the jack 2 is supported by the horizontal plate 103 and the vertical plate 7, wherein the vertical plate 7 is spliced ​​with the horizontal plate 103 and the frame plate 701 into a triangular structure, so that the horizontal plate 103 has good stability to support the jack 2.
