[0002] During the erection process of existing prefabricated bridges, a synchronous alternating jacking construction method is generally used to propel the prefabricated bridges. This setting requires precise and synchronous cooperation of multiple groups of jacking devices. However, the existing jacking devices do not have a pre-warning mechanism. Once an individual pushing device starts slowly or cannot start due to a malfunction, it will cause the prefabricated bridge to tilt during the propulsion process. In severe cases, the prefabricated bridge may even overturn, causing serious safety accidents and huge economic losses. Therefore, a synchronous alternating jacking construction method and device are proposed to address the above problems. Summary of the Invention

[0003] The object of the present invention is to provide a method and device for synchronous alternating jacking construction to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, wherein: a method and device for synchronous alternating jacking construction comprises a fixed frame, a jacking hydraulic mechanism and a correcting hydraulic rod, a pushing hydraulic rod is installed inside the fixed frame, an output end of the pushing hydraulic rod is fixedly connected to a pushing frame for pushing the jacking hydraulic mechanism to move, the correcting hydraulic rod is installed on the outside of the jacking hydraulic mechanism, and a guide module is fixedly connected to the bottom of the jacking hydraulic mechanism to ensure stable sliding of the jacking hydraulic mechanism;

[0006] A suction module is installed on the top of the fixed frame, and one end of the suction module is fixedly connected to the pushing hydraulic mechanism;

[0007] A pressing module installed inside the pushing frame is provided on one side of the pushing hydraulic mechanism inside the pushing frame, and a sliding column is fixedly connected to the other side of the pushing hydraulic mechanism inside the pushing frame, and the outer side of the sliding column is slidably connected to the pushing frame;

[0008] The other end of the pushing frame is fixedly connected with an early warning module, the outer side of the early warning module is slidably connected to the fixed frame, and a control unit is also installed inside the fixed frame.

[0009] During the erection process of existing prefabricated bridges, the prefabricated bridges are generally pushed forward by a synchronous alternating jacking construction method. This setting requires the precise synchronization of multiple jacking devices. However, the existing jacking devices do not have a pre-warning mechanism. Once an individual pushing device starts slowly or cannot start due to a malfunction, it will cause the prefabricated bridge to tilt during the advancement process. In severe cases, the prefabricated bridge may even overturn, causing serious safety accidents and huge economic losses. When using this device, it is first fixed in a suitable position, and the jacking hydraulic mechanism is adjusted by activating the correction hydraulic rod. After the adjustment is completed, the pushing frame is driven to move by activating the pushing hydraulic rod. At this time, the jacking hydraulic mechanism will not be displaced, but the pushing frame The early warning module is started. When multiple groups of early warning modules send signals to the control unit synchronously, it indicates that each pushing hydraulic rod is in normal use. Once a signal delay occurs or the signal cannot be received, it indicates that there is a pushing hydraulic rod failure. At this time, the control unit controls the pushing hydraulic rod to stop working, and the suction module continues to be sucked in. At this time, the staff needs to carry out timely maintenance. When multiple groups of early warning modules send signals to the control unit at the same time, they can work, and then the suction module is powered off and separated. At this time, the pushing frame can normally push the pushing hydraulic mechanism to move, and the guide module arranged at the bottom of the pushing hydraulic mechanism is used to ensure the stable movement of the pushing hydraulic mechanism, and the guide module has an automatic cleaning function to avoid impurities affecting the normal pushing work of the pushing hydraulic mechanism during long-term use.

[0010] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the suction module includes a frame and a connecting rod, the internal sliding connection of the frame is connected to the connecting rod, one end of the connecting rod is fixedly connected to the jacking hydraulic mechanism, the other end of the connecting rod is fixedly connected to a magnetic block, an electromagnet is provided on the other side of the magnetic block, and the outer side of the electromagnet is fixedly connected to the frame.

[0011] When the early warning module sends a signal to the control unit synchronously, the control unit controls the electromagnet to cut off the power and separate from the magnetic block to ensure the normal operation of the pushing hydraulic mechanism. Once multiple groups of early warning modules fail to send signals to the control unit synchronously, it means that there is a local failure or delay in pushing the hydraulic rod. At this time, the control unit controls the electromagnet to continue to be energized and in close contact with the magnetic block to avoid accidental pushing of the pushing hydraulic mechanism.

[0012] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the guide module includes a slide and a guide rod, the top of the slide is fixedly connected to the jacking hydraulic mechanism, the inside of the slide is slidably connected to the guide rod, the two ends of the guide rod are fixedly connected to the fixed frame, the outer side of the slide is rotatably connected to a rotating ring, and the inner side of the rotating ring is fixedly connected to evenly distributed cleaning brushes.

[0013] When the pushing hydraulic mechanism moves, the sliding table and guide rod are provided to ensure that the pushing hydraulic mechanism slides stably. During the sliding process, in order to ensure that the outer side of the guide rod is smooth and free of debris accumulation, the rotating ring and the internal cleaning brush provided at this time can pre-clean the guide rod to ensure that the pushing hydraulic mechanism slides stably.

[0014] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the slide is also fixedly connected to a first motor, the end of the main shaft of the first motor is fixedly connected to a driving gear, the outer side of the driving gear is meshed with a driven gear, and the interior of the driven gear is fixedly connected to a rotating ring.

[0015] When the cleaning brush is performing cleaning work, in order to further ensure the cleaning effect, the first motor is started to drive the driving gear to rotate, and the driving gear drives the driven gear to rotate, thereby rotating the rotating ring and the internal cleaning brush to rotate. At this time, the cleaning brush can rotate to clean the guide rod to ensure the cleaning quality.

[0016] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the pressing module includes a connecting frame and a second motor, the outer side of the connecting frame is fixedly connected to the pushing frame, the interior of the connecting frame is fixedly connected to the second motor, the main shaft end of the second motor is fixedly connected to a threaded shaft, the outer side of the threaded shaft is spirally connected to a threaded sleeve, and the other end of the threaded sleeve is fixedly connected to an extrusion plate.

[0017] When the pushing hydraulic mechanism completes an action and resets, the threaded shaft is driven to rotate by starting the second motor, thereby moving the threaded sleeve. At this time, the extrusion plate can be moved, thereby ensuring the movement of the pushing hydraulic mechanism and ensuring that the suction module is sucked in to fix the pushing hydraulic mechanism. At the same time, during transportation, the pushing hydraulic mechanism is ensured to be fixed. The second motor can be started to make the extrusion plate on one side squeeze the pushing hydraulic mechanism to fix it.

[0018] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the outer side of the threaded sleeve is fixedly connected to a fixed plate, the inner side of the fixed plate is slidably connected to a fixed column, and both ends of the fixed column are fixedly connected to the connecting frame.

[0019] In order to ensure the stable movement of the threaded sleeve, the fixed plate and the fixed column are arranged to cooperate to achieve the stable movement of the threaded sleeve and prevent the threaded sleeve from rotating itself.

[0020] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the early warning module includes a warning rod and a slider, one end of the warning rod is fixedly connected to the pushing frame, the bottom of the warning rod is slidably connected to the slider, the bottom of the slider is fixedly connected to the slide cylinder, the outer side of the slide cylinder is fixedly connected to the fixed frame, the top of the slide cylinder is fixedly connected to the outer convex frame, the inner part of the outer convex frame is fixedly connected to the guide frame, the outer side of the guide frame is slidably connected to the sliding plate, and the bottom of the sliding plate is fixedly connected to the tilting block, and a sensor installed inside the warning rod is provided above the sliding plate.

[0021] When the hydraulic rod is pushed to move the pushing frame, the pushing frame drives the early warning rod at one end to move. At this time, the early warning rod slides under the action of the slider. When multiple groups of early warning rods squeeze the tilting block at the same time and make it squeeze the sliding plate upward, the sliding plate contacts the sensor above. The sensor sends a signal to the control unit, indicating that the pushing hydraulic rod is working normally. Once a local sensor fails to transmit a signal or there is a signal delay, it means that the pushing hydraulic rod is delayed or malfunctions. At this time, staff need to repair it in time to avoid the situation where the pushing hydraulic rod cannot work synchronously and cause the beam to tilt or even fall over, which will cause huge economic losses.

[0022] As an optional solution of the method and device for synchronous alternating jacking construction described in the present invention, the guide frame is L-shaped, and a spring is provided on the outside of the guide frame, one end of the spring is fixedly connected to the outer convex frame, and the other end of the spring is fixedly connected to the sliding plate.

[0023] In order to ensure that the sliding plate and the sensor are not easily accidentally contacted, the spring provided can always squeeze the sliding plate. At the same time, in order to ensure that the sliding plate slides stably, the guide frame provided serves a good guiding purpose.

[0024] As an optional solution of the synchronous alternating jacking construction method and device described in the present invention, the lower end surface of the inclined block is inclined.

[0025] This setting ensures that during the pushing process of the warning rod, the warning rod slowly squeezes the tilting block, and under the action of the inclined surface of the tilting block, the tilting block slowly moves up, driving the sliding plate to move up and contact the sensor and send a signal to the control unit for the next action.

[0026] As an optional solution of the synchronous alternating jacking construction method and device of the present invention, the use steps are as follows:

[0027] Step 1: Connect the steel guide beam to the prefabricated beam body, and then install the device at a suitable position under the prefabricated bridge;

[0028] Step 2: When installing the prefabricated beam, first start multiple sets of jacking hydraulic mechanisms to lift the prefabricated beam, then start the pushing hydraulic rod to drive the pushing frame to move, at this time the pushing frame and the sliding column slide;

[0029] Step 3: The push frame drives the warning module to start when it moves. When multiple warning modules are started, it means that the hydraulic rod is working normally and the suction module is powered off at the same time.

[0030] Step 4: The pushing frame moves slowly and contacts the pushing hydraulic mechanism, slowly pushing the pushing hydraulic mechanism to move, thereby realizing the movement of the precast beam;

[0031] Step 5: When the push hydraulic mechanism moves, the push hydraulic mechanism drives the guide module to move to ensure normal operation;

[0032] Step 6: After completing the movement of a precast beam, the pressing module is activated to reset the jacking hydraulic mechanism to ensure the normal operation of the next cycle. At the same time, the pressing module serves to fix the jacking hydraulic mechanism during transportation.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] The present invention provides an early warning module. When the equipment is started, its pushing hydraulic rod pre-pushes the pushing frame to move to a certain extent. At this time, the pushing hydraulic mechanism does not move. The early warning modules are driven to start synchronously by multiple groups of pushing frames, indicating that the pushing hydraulic rod is started normally. The pushing hydraulic rod is continued to be started. At this time, the pushing frame can push the pushing hydraulic mechanism to move slowly, which is used for the propulsion of the prefabricated bridge. Once the individual pushing hydraulic rods cannot move normally during startup, the other early warning modules move normally. At this time, it indicates that the equipment has failed. The control unit controls the equipment to stop in time to avoid major accidents. This arrangement can perform pre-detection before the pushing hydraulic mechanism works normally, ensuring that the equipment can start stably and avoiding accidents that cause huge economic losses.

[0035] By pushing the hydraulic rod, the push frame moves, and then the warning rod moves. When the warning rod moves and squeezes the tilting block, the tilting block drives the sliding plate to squeeze the sensor above. At this time, multiple groups of sensors simultaneously send signals to the control unit, indicating that the equipment is operating normally and the suction module is powered off. Once some sensors cannot accurately send signals, it means that the equipment has failed. The control unit controls the hydraulic rod to stop in time, and the suction module continues to be powered, requiring timely maintenance by staff.

[0036] When the push hydraulic mechanism moves normally, it drives the slide to move outside the guide rod, and the first motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, and then the rotating ring drives the internal cleaning brush to rotate. At this time, the surface of the guide rod can be cleaned to prevent external impurities from affecting the normal propulsion of the equipment.

[0037] When a pushing work is completed, the second motor is started to drive the threaded shaft to rotate, and the threaded shaft drives the threaded sleeve to move, and the pushing hydraulic mechanism is reset under the action of the extrusion plate, thereby ensuring that the next cycle can work normally. At the same time, during transportation, the pressing module is used to squeeze the pushing hydraulic mechanism, and the purpose of fixing the pushing hydraulic mechanism is achieved with the cooperation of the pushing frame.

[0047] A method and device for synchronous alternating jacking construction, comprising a fixed frame 1, a jacking hydraulic mechanism 5, and a corrective hydraulic rod 6. A push hydraulic rod 2 is installed inside the fixed frame 1, and the output end of the push hydraulic rod 2 is fixedly connected to a push frame 4 for pushing the jacking hydraulic mechanism 5 to move. The corrective hydraulic rod 6 is installed on the outside of the jacking hydraulic mechanism 5, and the bottom of the jacking hydraulic mechanism 5 is fixedly connected to a guide module 7 that ensures stable sliding of the jacking hydraulic mechanism 5.

[0048] A suction module 3 is installed on the top of the fixed frame 1, and one end of the suction module 3 is fixedly connected to the pushing hydraulic mechanism 5;

[0049] A pressing module 8 is provided on one side of the pushing hydraulic mechanism 5 inside the pushing frame 4. A sliding column 10 is fixedly connected to the other side of the pushing hydraulic mechanism 5 inside the pushing frame 4. The outer side of the sliding column 10 is slidably connected to the pushing frame 4.

[0050] The other end of the pushing frame 4 is fixedly connected with an early warning module 9 , and the outer side of the early warning module 9 is slidably connected to the fixed frame 1 , and a control unit is also installed inside the fixed frame 1 .

[0051] The above usage steps are as follows:

[0052] Step 1: Connect the steel guide beam to the prefabricated beam body, and then install the device at a suitable position under the prefabricated bridge;

[0053] Step 2: When installing the prefabricated beam, first start the multiple groups of jacking hydraulic mechanisms 5 to lift the prefabricated beam, then start the pushing hydraulic rod 2 to drive the pushing frame 4 to move, at this time the pushing frame 4 and the sliding column 10 slide;

[0054] Step 3: The push frame 4 drives the warning module 9 to start when moving. When multiple groups of warning modules 9 are started, it means that the hydraulic rod 2 is working normally and the suction module 3 is powered off.

[0055] Step 4: The pushing frame 4 moves slowly and contacts the pushing hydraulic mechanism 5, slowly pushing the pushing hydraulic mechanism 5 to move, thereby realizing the movement of the precast beam;

[0056] Step 5: When the push hydraulic mechanism 5 moves, the push hydraulic mechanism 5 drives the guide module 7 to move to ensure normal operation;

[0057] Step 6: After completing the movement of a precast beam, the pressing module 8 is started to drive the pushing hydraulic mechanism 5 to reset, ensuring that the next cycle works normally. At the same time, the pressing module 8 serves to fix the pushing hydraulic mechanism 5 during transportation.

[0058] In the process of erecting existing prefabricated bridges, the construction method of synchronous alternating jacking is generally used to propel the prefabricated bridge. This setting requires precise and synchronous cooperation of multiple groups of jacking devices. However, the existing jacking devices do not have a pre-warning mechanism. Once an individual pushing device starts slowly or cannot start due to a malfunction, it will cause the prefabricated bridge to tilt during the propulsion process. In severe cases, the prefabricated bridge may even overturn, causing serious safety accidents and huge economic losses. When the present device is in use, it is first fixed in a suitable position, and the jacking hydraulic mechanism 5 is adjusted by starting the correcting hydraulic rod 6. The pushing hydraulic rod, the correcting hydraulic rod and the jacking hydraulic mechanism belong to the existing technology in this field, so the internal structure will not be repeated. After the adjustment is completed, the pushing frame 4 is driven to move by starting the pushing hydraulic rod 2. At this time, the jacking hydraulic mechanism 5 will not be displaced, but The pushing frame 4 drives the early warning module 9 to start. When multiple groups of early warning modules 9 synchronously send signals to the control unit, it indicates that each pushing hydraulic rod 2 is in normal use. Once a signal delay occurs or the signal cannot be received, it indicates that there is a push hydraulic rod 2 failure. At this time, the control unit controls the pushing hydraulic rod 2 to stop working, and the suction module 3 continues to be sucked. At this time, the staff needs to carry out timely maintenance. When multiple groups of early warning modules 9 send signals to the control unit at the same time, they can work, and then the suction module 3 is powered off and separated. At this time, the pushing frame 4 can normally push the pushing hydraulic mechanism 5 to move. In this way, the bridge can be installed by cyclically and synchronously pushing alternately. The guide module 7 arranged at the bottom of the pushing hydraulic mechanism 5 is used to ensure the stable movement of the pushing hydraulic mechanism 5, and the guide module 7 has an automatic cleaning function to avoid impurities affecting the normal pushing work of the pushing hydraulic mechanism 5 during long-term use.

[0059] Example 2

[0060] This embodiment is an improvement made to Example 1. Figure 1 and Figure 2 Specifically, the above-mentioned suction module 3 includes a frame 301 and a connecting rod 302. The connecting rod 302 is slidably connected to the inside of the above-mentioned frame 301. One end of the above-mentioned connecting rod 302 is fixedly connected to the pushing hydraulic mechanism 5. The other end of the above-mentioned connecting rod 302 is fixedly connected to a magnetic block 303. An electromagnet 304 is provided on the other side of the above-mentioned magnetic block 303. The outer side of the above-mentioned electromagnet 304 is fixedly connected to the frame 301.

[0061] When the early warning module 9 synchronously sends a signal to the control unit, the control unit controls the electromagnet 304 to cut off the power and separate from the magnetic block 303 to ensure the normal operation of the pushing hydraulic mechanism 5. Once multiple groups of early warning modules 9 fail to synchronously send signals to the control unit, it indicates that there is a local failure or delay in pushing the hydraulic rod 2. At this time, the control unit controls the electromagnet 304 to continue to be energized and in close contact with the magnetic block 303 to avoid the pushing hydraulic mechanism 5 from being pushed by mistake.

[0062] Example 3

[0063] This embodiment is an improvement made to Example 2. Figure 1 、 Figure 3 and Figure 4 Specifically, the guide module 7 includes a slide 701 and a guide rod 702. The top of the slide 701 is fixedly connected to the push hydraulic mechanism 5. The interior of the slide 701 is slidably connected to the guide rod 702. Both ends of the guide rod 702 are fixedly connected to the fixed frame 1. The outer side of the slide 701 is rotatably connected to a rotating ring 703, and the inner side of the rotating ring 703 is fixedly connected to evenly distributed cleaning brushes 707.

[0064] When the pushing hydraulic mechanism 5 moves, the sliding platform 701 and the guide rod 702 are set to ensure that the pushing hydraulic mechanism 5 slides stably. In the sliding process, in order to ensure that the outer side of the guide rod 702 is smooth and free of debris accumulation, the rotating ring 703 and the internal cleaning brush 707 can pre-clean the guide rod 702 to ensure that the pushing hydraulic mechanism 5 slides stably.

[0065] Example 4

[0066] This embodiment is an improvement made to the implementation of Example 3. Figure 3 Specifically, the slide 701 is also fixedly connected to a first motor 706, the main shaft end of the first motor 706 is fixedly connected to a driving gear 705, the outer side of the driving gear 705 is meshed with a driven gear 704, and the interior of the driven gear 704 is fixedly connected to a rotating ring 703.

[0067] When the cleaning brush 707 is performing the cleaning work, in order to further ensure the cleaning effect, the first motor 706 is started to drive the driving gear 705 to rotate, and the driving gear 705 drives the driven gear 704 to rotate, thereby causing the rotating ring 703 and the internal cleaning brush 707 to rotate. At this time, the cleaning brush 707 can rotate to clean the guide rod 702 to ensure the cleaning quality.

[0068] Example 5

[0069] This embodiment is an improvement made to the fourth embodiment. Figure 1 and Figure 5 Specifically, the pressing module 8 includes a connecting frame 801 and a second motor 802. The outer side of the connecting frame 801 is fixedly connected to the pushing frame 4. The interior of the connecting frame 801 is fixedly connected to the second motor 802. The end of the main shaft of the second motor 802 is fixedly connected to a threaded shaft 803. The outer side of the threaded shaft 803 is spirally connected to a threaded sleeve 804. The other end of the threaded sleeve 804 is fixedly connected to an extrusion plate 805.

[0070] When the pushing hydraulic mechanism 5 completes an action and resets, the threaded shaft 803 is driven to rotate by starting the second motor 802, and then the threaded sleeve 804 is moved. At this time, the extrusion plate 805 can be moved, thereby ensuring that the pushing hydraulic mechanism 5 moves, ensuring that the suction module 3 is sucked in to fix the pushing hydraulic mechanism 5, and at the same time, during transportation, to ensure that the pushing hydraulic mechanism 5 is fixed, the second motor 802 can be started to make the extrusion plate 805 on one side squeeze the pushing hydraulic mechanism 5 for fixation.

[0071] Example 6

[0072] This embodiment is an improvement made to the fifth embodiment. Figure 5 Specifically, the outer side of the threaded sleeve 804 is fixedly connected to a fixing plate 806 , the inner side of the fixing plate 806 is slidably connected to a fixing column 807 , and both ends of the fixing column 807 are fixedly connected to the connecting frame 801 .

[0073] In order to ensure the stable movement of the threaded sleeve 804, the fixed plate 806 cooperates with the fixed column 807 to achieve stable movement of the threaded sleeve 804 and prevent the threaded sleeve 804 from rotating itself.

[0074] Example 7

[0075] This embodiment is an improvement made to Example 6. Figure 1 and Figure 6 Specifically, the above-mentioned early warning module 9 includes an early warning rod 901 and a slider 902. One end of the above-mentioned early warning rod 901 is fixedly connected to the pushing frame 4. The bottom of the above-mentioned early warning rod 901 is slidably connected to the slider 902. The bottom of the above-mentioned slider 902 is fixedly connected to the slide 903. The outer side of the above-mentioned slide 903 is fixedly connected to the fixed frame 1. The top of the above-mentioned slide 903 is fixedly connected to the outer convex frame 904. The interior of the above-mentioned outer convex frame 904 is fixedly connected to a guide frame 905. The outer side of the above-mentioned guide frame 905 is slidably connected to a sliding plate 906, and the bottom of the sliding plate 906 is fixedly connected to a tilting block 907. A sensor 909 installed inside the early warning rod 901 is provided above the above-mentioned sliding plate 906.

[0076] When the pushing hydraulic rod 2 drives the pushing frame 4 to move, its pushing frame 4 drives the early warning rod 901 at one end to move. At this time, the early warning rod 901 slides under the action of the slider 902. When multiple groups of early warning rods 901 squeeze the tilting block 907 at the same time and make it squeeze the sliding plate 906 upward, its sliding plate 906 contacts the upper sensor 909. The sensor 909 sends a signal to the control unit, indicating that the pushing hydraulic rod 2 is working normally. Once the local sensor 909 cannot transmit the signal, or there is a signal delay, it means that the pushing hydraulic rod 2 is delayed or malfunctions. At this time, the staff needs to repair it in time to avoid the situation where the pushing hydraulic rod 2 cannot work synchronously and causes the beam to tilt or even fall over, which will cause huge economic losses.

[0077] Example 8

[0078] This embodiment is an improvement made to Example 7. Figure 6 Specifically, the guide frame 905 is L-shaped, and a spring 908 is provided on the outside of the guide frame 905. One end of the spring 908 is fixedly connected to the outer convex frame 904, and the other end of the spring 908 is fixedly connected to the sliding plate 906.

[0079] In order to ensure that the sliding plate 906 and the sensor 909 are not easily accidentally contacted, the spring 908 is provided to constantly squeeze the sliding plate 906. At the same time, in order to ensure that the sliding plate 906 slides stably, the guide frame 905 serves a good guiding purpose.

[0080] Example 9

[0081] This embodiment is an improvement made to Example 8. Figure 6 Specifically, the lower end surface of the inclined block 907 is inclined.

[0082] This arrangement ensures that during the pushing process of the warning rod 901, the warning rod 901 slowly squeezes the tilting block 907, and under the action of the inclined surface of the tilting block 907, the tilting block 907 slowly moves upward, driving the sliding plate 906 to move upward and contact with the sensor 909 and send a signal to the control unit for the next action.
