[0048] An embodiment of the present utility model provides a walking jacking device, which is applied to the moving operation of the steel beam of a bridge. The walking jacking device has the advantages of simple structure, convenient operation, and accurate support position, and can effectively improve the efficiency and safety of the moving operation of the bridge steel beam.

[0049] Please refer to Figures 1 to 3 , the walking jacking device includes a lower support frame 1, a first telescopic driving member 2, an upper support frame 3, a second telescopic driving member 5, a transverse sliding block 6, and a third telescopic driving member 8. Among them, the first telescopic driving member 2 is in transmission connection with the lower support frame 1 and is used to drive the lower support frame 1 to move in the vertical direction.

[0050] When moving the steel beam of a bridge, a walking jacking device is placed at the bottom of the steel beam, and the transverse sliding block 6 bears the steel beam. The lower support frame 1 is driven by the first telescopic driving member 2 to move in the vertical direction, so that the height of the transverse sliding block 6 increases, thereby providing support for the steel beam of the bridge.

The transverse sliding block 6 is driven by the third telescopic driving member 8 to move along the width direction of the lower support frame 1, thereby driving the steel beam of the bridge to move along the width direction of the lower support frame 1. In this way, through the coordinated action of the first telescopic driving member 2, the second telescopic driving member 5 and the third telescopic driving member 8, precise support and position adjustment of the steel beam are achieved. Therefore, the walking jacking device has the advantages of simple structure, convenient operation, accurate support position, etc., and can effectively improve the efficiency and safety of the moving operation of the bridge steel beam.

[0051] In order to improve the accuracy of the movement of the upper support frame 3 relative to the lower support frame 1, in this embodiment, the walking jacking device may further include a first guiding member 4. Among them, the upper support frame 3 is connected to the first guiding member 4, and the first guiding member 4 is connected to the top of the lower support frame 1 for restricting the movement of the upper support frame 3 along the length direction of the lower support frame 1.

[0052] By providing the first guiding member 4, the movement of the upper support frame 3 along the length direction of the lower support frame 1 can be effectively restricted, so as to ensure that the steel beam moves along the length direction of the lower support frame 1 and ensure the accuracy of the moving direction.

The top of the first sliding block 42 is fixedly connected to the upper support frame 3, and the first sliding block 42 is slidably engaged with the first guide rail 41.

[0054] By setting the first guide rail 41 to extend along the length direction of the lower support frame 1 and the first sliding block 42 to be slidably engaged with the first guide rail 41, the upper support frame 3 moves along the length direction of the lower support frame 1, ensuring that the steel beam moves along the length direction of the lower support frame 1 and the position of the steel beam is more accurate.

[0055] It should be noted that the cross-sectional shape of the first guide rail 41 is not specifically limited. For example, it can be T-shaped, dovetail-shaped, etc. The cross-sectional shape of the chute on the first sliding block 42 that cooperates with the first guide rail 41 matches the cross-sectional shape of the first guide rail 41. In this embodiment, there are two first guide rails 41, and the two first guide rails 41 are arranged in parallel on the upper surface of the lower support frame 1 to improve the accuracy of the movement of the upper support frame 3 along the length direction of the lower support frame 1.

[0056] In order to improve the accuracy of the lateral movement of the lateral sliding block 6 relative to the upper support frame 3, in this embodiment, the walking jacking device may further include a second guiding member 7. Wherein, the lateral sliding block 6 is in sliding fit with the second guiding member 7, and the second guiding member 7 is connected to the upper support frame 3 for restricting the lateral movement of the lateral sliding block 6 along the width direction of the lower support frame 1.

[0057] By providing the second guiding member 7, the lateral movement of the lateral sliding block 6 along the width direction of the lower support frame 1 can be effectively restricted, so as to ensure that the steel beam moves along the width direction of the lower support frame 1 and ensure the accuracy of the moving direction.

[0058] In an alternative embodiment, the second guiding member 7 may include a second guide rail 71. Wherein, the second guide rail 71 is fixedly installed on the upper support frame 3, the extending direction of the second guide rail 71 is the same as the width direction of the lower support frame 1, and the lateral sliding block 6 is in sliding fit with the second guide rail 71.

[0059] By arranging the second guide rail 71 to extend along the width direction of the lower support frame 1 and the lateral sliding block 6 is in sliding fit with the second guide rail 71, the lateral sliding block 6 moves along the width direction of the lower support frame 1, ensuring that the steel beam moves along the width direction of the lower support frame 1 and the position of the steel beam is more accurate.

[0060] It should be noted that the cross-sectional shape of the second guide rail 71 is not specifically limited. For example, it can be T-shaped, dovetail-shaped, etc. The cross-sectional shape of the chute on the second sliding block that cooperates with the second guide rail 71 matches the cross-sectional shape of the second guide rail 71. In this embodiment, there are two second guide rails 71, and the two second guide rails are arranged in parallel on the upper surface of the upper support frame 3 to improve the accuracy of the lateral movement of the lateral sliding block 6 along the width direction of the lower support frame 1.

[0061] Please refer to Figures 1 to 4 , in an alternative embodiment, the first telescopic driving member 2 is a jacking oil cylinder 21, and the lower support frame 1 includes a support table 11, a plurality of telescopic struts 12 and a base 13. Wherein, the support table 11 is connected to the tops of the plurality of telescopic struts 12, the bottoms of the plurality of telescopic struts 12 are connected to the base 13, the plurality of telescopic struts 12 are arranged vertically, and an accommodating cavity is formed by the lower side of the support table 11, the plurality of telescopic struts 12 and the base 13. The jacking oil cylinder 21 is accommodated in the accommodating cavity. The upper support frame 3 is movably connected to the upper surface of the support table 11. The moving end of the jacking oil cylinder 21 is connected to the lower side of the support table 11 for driving the support table 11 to move in the vertical direction and causing the plurality of telescopic struts 12 to expand and contract in the vertical direction. In this embodiment, the first guide rail 41 is fixedly installed on the upper surface of the support table 11.

[0062] The first telescopic driving member 2 adopts a lifting oil cylinder 21, which is convenient for control. When moving the steel beam of the bridge, the lifting oil cylinder 21 is controlled to expand and contract. The moving end of the lifting oil cylinder 21 jacks up the support platform 11, so that the upper support frame 3 moves in the vertical direction. At this time, the plurality of telescopic struts 12 expand and contract in the vertical direction, and finally the transverse movement slider 6 rises, increasing the height of the entire support system, thereby providing support for the bridge steel beam.

[0063] A pressure sensor 9 is fixedly installed on the lifting oil cylinder 21. The pressure sensor 9 is used to monitor the pressure value of the lifting oil cylinder 21 during the lifting process. Optionally, the pressure sensor 9 is installed on the cylinder wall of the lifting oil cylinder 21 and close to the connection of the hydraulic system, so as to accurately monitor the pressure change in the hydraulic system.

[0064] It should be noted that the number of the lifting oil cylinders 21 is not specifically limited and can be selected as multiple. In this embodiment, there are two lifting oil cylinders 21, and the two lifting oil cylinders 21 are arranged side by side at intervals in the accommodation cavity.

[0065] In an alternative embodiment, the second telescopic driving member 5 is a pushing oil cylinder 51, and the walking type pushing device further includes a mounting seat 14. Among them, the mounting seat 14 is fixedly arranged on the top of the lower support frame 1. The fixed end of the pushing oil cylinder 51 is fixedly connected to the mounting seat 14, and the moving end of the pushing oil cylinder 51 is fixedly connected to one side of the upper support frame 3.

[0066] The second telescopic driving member 5 adopts a pushing oil cylinder 51, which is convenient for control. By controlling the pushing oil cylinder 51 to expand and contract, the upper support frame 3 can move along the length direction of the lower support frame 1, thereby driving the bridge steel beam to move along the length direction of the lower support frame 1.

[0067] It should be noted that the number of the pushing oil cylinders 51 is not specifically limited and can be selected as multiple. In this embodiment, there are three pushing oil cylinders 51, and the three pushing oil cylinders 51 are arranged side by side at intervals in sequence on the mounting seat 14, and their moving ends extend out of the mounting seat 14 and are fixedly connected to one side of the upper support frame 3.

[0068] In an alternative embodiment, the third telescopic driving member 8 is two alignment oil cylinders 81 symmetrically arranged on opposite sides of the upper support frame 3. Among them, the fixed end of the alignment oil cylinder 81 is fixedly connected to the upper support frame 3, and the moving end of the alignment oil cylinder 81 is fixedly connected to the transverse movement slider 6.

[0069] The third telescopic driving member 8 adopts a deviation rectifying oil cylinder 81, which is used to adjust the position of the transverse sliding block 6, so as to adjust the supporting position of the bridge steel beam. The operation of the deviation rectifying oil cylinder 81 can make the supporting position more accurate and stable. When the deviation rectifying oil cylinder 81 expands and contracts, the transverse sliding block 6 moves along the width direction of the lower support frame 1, so as to drive the bridge steel beam to move along the width direction of the lower support frame 1 and adjust the position of the bridge steel beam.

[0070] It should be noted that each transverse sliding block 6 is correspondingly connected to two deviation rectifying oil cylinders 81, that is, two deviation rectifying oil cylinders 81 form a group to adjust the position of one transverse sliding block 6. In this embodiment, there are two transverse sliding blocks 6, and the two transverse sliding blocks 6 are arranged side by side and spaced apart in the upper support frame 3. Each of the two transverse sliding blocks 6 is connected to a group of deviation rectifying oil cylinders 81.

[0071] Displacement sensors (not shown in the figure) are fixedly installed on the jacking oil cylinder 21, the pushing oil cylinder 51 and the deviation rectifying oil cylinder 81, respectively, for monitoring the displacement of the moving ends of the jacking oil cylinder 21, the pushing oil cylinder 51 and the deviation rectifying oil cylinder 81. Optionally, the displacement sensor is installed on the piston or piston rod of each hydraulic cylinder. When installing, the displacement sensor should be tightly connected to the piston or piston rod and correctly positioned to ensure accurate measurement of the position. In addition, the displacement sensor can adopt a linear transmitter. The linear transmitter determines the position by measuring the displacement of the piston position in the jacking oil cylinder 21, the pushing oil cylinder 51 and the deviation rectifying oil cylinder 81 relative to a fixed reference point. The linear sensor uses its own internal screw or magnetic encoder to connect with the piston and converts the displacement into an electrical signal output. By monitoring the output signal of the displacement sensor, the displacement of the moving ends of the jacking oil cylinder 21, the pushing oil cylinder 51 and the deviation rectifying oil cylinder 81 can be obtained, so as to be able to monitor the movement of the steel beam in real time.

[0072] Please refer to Figure 4, in an optional embodiment, the walking jacking device may further include a hydraulic control system 100. Among them, the hydraulic control system 100 includes a hydraulic pump unit 110, a control valve group 120, a hydraulic oil tank 130, monitoring sensors (not shown in the figure), and a controller 140. The hydraulic oil tank 130 is used to store hydraulic oil, and cools, filters, and cleans the hydraulic oil through an oil circulation system provided thereon. The hydraulic pump unit 110 is connected to the hydraulic oil tank 130 and is respectively connected to the jacking cylinder 21, the pushing cylinder 51, and the deviation correction cylinder 81, and is used to provide the fluid pressure required by the hydraulic system, and suck and supply the liquid from the hydraulic oil tank 130 to the jacking cylinder 21, the pushing cylinder 51, and the deviation correction cylinder 81. The control valve group 120 is respectively connected to the hydraulic flow paths of the jacking cylinder 21, the pushing cylinder 51, and the deviation correction cylinder 81, and is used to control the flow direction, flow rate, and pressure of the hydraulic oil in the hydraulic system. The controller 140 is respectively connected to the control valve group 120 and the hydraulic pump unit 110, and is used to control the opening and closing of the control valve group 120 and the hydraulic pump unit 110. The monitoring sensors are connected to the controller 140 and are used to monitor various hydraulic parameters in the hydraulic system, such as pressure, flow rate, temperature, position, etc. These monitoring sensors can provide real-time feedback information to the controller 140 to monitor the hydraulic value and the jacking displacement value during the process of jacking the steel beam, so as to achieve the closed-loop control of the system.

[0073] Optionally, the hydraulic pump unit 110 includes a vertical jacking pump group 111, a longitudinal propulsion pump group 112, and a lateral deviation correction pump group 113. The vertical jacking pump group 111, the longitudinal propulsion pump group 112, and the lateral deviation correction pump group 113 are all connected to the hydraulic oil tank 130. Among them, the vertical jacking pump group 111 is connected to the hydraulic flow path of the jacking cylinder 21, the longitudinal propulsion pump group 112 is connected to the hydraulic flow path of the pushing cylinder 51, and the lateral deviation correction pump group 113 is connected to the hydraulic flow path of the deviation correction cylinder 81. The control valve group 120 respectively controls the flow direction, flow rate, and pressure of the hydraulic oil in the jacking cylinder 21, the pushing cylinder 51, and the deviation correction cylinder 81.

[0074] The working principle of the walking jacking device provided in this embodiment is as follows:

[0075] When moving the steel beam of the bridge, place the walking jacking device at the bottom of the steel beam so that the transverse sliding block 6 bears the steel beam. Control the telescopic movement of the jacking cylinder 21. The jacking cylinder 21 moves the upper support frame 3 in the vertical direction. When the jacking cylinder 21 extends, the support platform 11 is lifted, so that the height of the entire support system increases, thereby providing support for the bridge steel beam.

[0076] Then, control the telescopic movement of the pushing cylinder 51. The pushing cylinder 51 is fixed on the lower support frame 1 and connected to the upper support frame 3. When the pushing cylinder 51 telescopes, the upper support frame 3 can move along the length direction of the lower support frame 1, thereby driving the bridge steel girder to move along the length direction of the lower support frame 1.

[0077] The deviation-correcting cylinders 81 are located on both sides of the upper support frame 3 and are used to adjust the position of the transverse sliding block 6, thereby adjusting the supporting position of the walking jacking device on the bridge steel girder. The operation of the deviation-correcting cylinders 81 can make the supporting position more accurate and stable. And when the deviation-correcting cylinders 81 telescope, the transverse sliding block 6 moves along the width direction of the lower support frame 1, thereby driving the bridge steel girder to move along the width direction of the lower support frame 1 to adjust the position of the bridge steel girder.

[0078] Moreover, the pressure sensor 9 can be used to monitor the pressure value during the jacking process of the jacking cylinder 21 to prevent safety accidents caused by overload. The displacement sensor can monitor the jacking displacement of the bridge and the displacement amounts along the length direction and width direction of the lower support frame 1, so as to realize the real-time monitoring and control of the working state of the walking jacking device.

[0079] Through the coordinated action of the jacking cylinder 21, the pushing cylinder 51 and the deviation-correcting cylinders 81, the precise support and adjustment of the steel girder are realized. Through the application of the pressure sensor 9 and the displacement sensor, the working state of each cylinder and the displacement of the bridge can be monitored in real time, thereby ensuring the safety and stability of the walking jacking device. In addition, the walking jacking device has the advantages of simple structure, convenient operation, accurate support position, etc., and can effectively improve the efficiency and safety of the moving operation of the bridge steel girder.
