Description

Technical Field

[0001] This utility model relates to the field of bridge jacking technology, and more specifically, it relates to a walking jacking construction device. Background Technology

[0002] Conventional step-by-step jacking construction is an important construction method in bridge engineering. The specific jacking process is illustrated in Publication No. CN 106012853 A, which discloses a step-by-step jacking construction method. In this method, the main control center sets standard values ​​for horizontal jacking displacement, lifting displacement, and component deviation direction. The horizontal jacking value, lifting value, and component deviation direction value of each jacking unit platform are measured in real time. These real-time measured parameters are compared with the set parameters by the main control center. After the lifting jacks lift the main beam away from the beam-lowering support, the real-time measured horizontal jacking value, lifting value, and component deviation direction value are compared with the set values ​​and adjusted to match them. Its advantages include enabling three-dimensional control of multiple jacking units by a single central control system to achieve continuous synchronous operation, high control precision, reduced labor intensity, and reduced labor costs; compact and simple structure, easy disassembly and assembly, low cost, and small working space; once installed, the equipment can be used until completion, overcoming the disadvantage of conventional traction methods that can only move forward and not backward; and dynamic correction function, which can correct deviations in a timely manner during the movement.

[0003] Because the jacking operation has high requirements for temporary supports and tracks, and the existing walking jacking construction equipment generally has its jacking device directly installed on the pier or installed on the top of the pier through a steel beam support, such support structure has relatively low strength and stability, small stress surface, is easy to be damaged, and has safety hazards.

[0011] Furthermore, the second spreader beam is connected to the temporary support and the first spreader beam by welding or bolting.

[0012] Furthermore, the walking machine includes an auxiliary track, a horizontal jack, and a sliding shoe.

It also includes temporary supports 5, a first flat beam 6, and a second flat beam 7. The temporary supports 5 are symmetrically distributed on both sides of a pier 8. The second flat beam 7 is horizontally installed on top of the temporary supports 5, with its bottom contacting the top surface of the pier 8, forming a three-point support. The first flat beam 6 is installed on top of the second flat beam 7 directly above the pier 8. The walking machine 3 is installed on the first flat beam 6. The vertical jacks 4 are symmetrically distributed on both sides of the walking machine 3, and are installed on top of the second flat beam 7. The vertical jacks 4 are independently placed and can be adjusted according to site conditions.

In this device, the support structure consisting of pier 8, temporary support 5, first spreader beam 6, and second spreader beam 7 jointly supports the walking machine 3 and vertical jack 4, effectively improving support stability.

In this control system, centralized control from the main control console and distributed hydraulic pump stations enable self-balancing of the walking machines at each point. During the vertical lifting and lowering of components, the equipment at each control point is synchronized and pressure is maintained, reducing construction risks.

[0026] The walking jacking construction device of this utility model adopts a support structure composed of a first flat beam 6, a second flat beam 7, a temporary support 5, and a pier 8, which improves the structural strength of the support structure, thereby effectively improving the stability and safety during the walking jacking construction process. In addition, the temporary support 5 and the pier 8 form three support points, which allows the width of the first flat beam 6 and the second flat beam 7 to be designed to be larger, and the jacking distance can be effectively extended, greatly improving the construction efficiency. At the same time, the installation platform of the support structure occupies less space and is more convenient to construct compared with the existing technology.

[0027] Preferably, several steel plates 11 are movably placed on the top of the walking machine 3 and the vertical jack 4. Specifically, the steel plates 11 are stacked on the top of the corresponding sliding shoe 33 of the walking machine 3 and the top of the vertical jack 4 to adjust the elevation.

The two-to-four valve group 12 is equipped in the oil circuit. The two-to-four valve group 12 is equipped with a check valve, an overflow valve and a balance valve to ensure that the equipment maintains pressure when the vertical jack 4 lifts and lowers the components, and at the same time protects the vertical jack from exceeding the limit pressure, thus ensuring construction safety. The pressure sensor 9 is installed at the valve of the two-to-four valve group 12 to realize the installation of the pressure sensor 9 and improve the installation stability of the pressure sensor.

[0029] Preferably, the data line corresponding to the hydraulic pump station 2 is provided with a data line hub 13, wherein the data lines corresponding to the pressure sensor 9 and the displacement sensor 10 are connected to the data line hub 13 through data line plugs to realize quick connection and conduction of the data lines.

[0030] Preferably, the height of the temporary support 5 is adapted to the height of the pier 8, so that the temporary support 5 and the pier 8 are stressed on the same plane. In other embodiments, the height of the temporary support 5 may be less than the height of the pier 8. In this case, the bottom of the temporary support 5 needs to be fixedly connected to the pier 8 to achieve stress distribution. The height and width of the second spreader beam 7 are both greater than the height and width of the first spreader beam 6, which meets the requirements of step-by-step jacking while further improving construction stability.

[0031] Preferably, the second spreader beam 7 is connected to the temporary support 5 and the first spreader beam 6 by welding or bolting, thereby achieving a fixed installation of the second spreader beam 7 to the temporary support 5 and the first spreader beam 6. In this embodiment, the second spreader beam 7 is preferably bolted to the temporary support 5 and the first spreader beam 6 for easy assembly and disassembly.

[0032] Preferably, the walking machine 3 includes an auxiliary track 31, a horizontal jack 32, and a sliding shoe 33. The auxiliary track 31 is mounted on the first flat beam 6, the horizontal jack 32 is mounted on the auxiliary track 31, and the displacement sensor 10 corresponding to the walking machine 3 is mounted on one side of the auxiliary track 31. The sliding shoe 33 is slidably mounted on the auxiliary track 31 and connected to one end of the horizontal jack 32. Extension and retraction of the horizontal jack 32 can drive the sliding shoe 33 to move horizontally. Furthermore, a third flat beam 15 is provided on the top of the sliding shoe 33, on which steel plates 11 are placed. By providing the third flat beam 15, the placement area can be increased, allowing more steel plates 11 to be placed, thereby improving support stability.

[0033] Preferably, correction jacks 14 are provided on both sides of the sliding shoe 33, and the correction jacks 14 are connected to the hydraulic pump station 2 through hydraulic oil pipes. The displacement sensor 10 corresponding to the walking machine 3 is used to detect the bridge pushing distance. The displacement sensor 10 corresponding to the vertical jack 4 is used to detect the bridge lifting distance.

[0034] The walking jacking construction device of this utility model, during construction:

[0035] First, the main control console 1 connects to the hydraulic pump station 2 via a wireless bridge. The transmitted data is displayed visually, showing that the data is normal and the conditions for jacking are met. After the personnel verify that there are no errors, the main control console 1 issues a command, and the hydraulic pump station 2 receives and executes the command.

[0036] The jacking phase: The main control console 1 controls the hydraulic pump station 2 to independently control the walking machine 3 through the hydraulic oil pipe. The correction jack 14 adjusts the forward angle of the sliding shoe 33 in advance. The horizontal jack 32 pushes the sliding shoe 33 forward. During the process, the pressure sensor group 9 and displacement sensor 10 corresponding to the walking machine 3 monitor its working status at all times and transmit the data back to the main control console in real time. If the main control console 1 judges that the jacking is normal, it continues to jack. If the data is abnormal, it alarms and stops working. After the equipment personnel check and repair, the jacking work continues. After the auxiliary track 31 is jacked to complete its stroke, the sliding shoe adjustment phase begins.

[0037] Adjusting the slipper stage: The main control console 1 controls the hydraulic pump station 2 to independently control the vertical jack 4 through the hydraulic oil pipe. During the jacking process, the two-way four-valve group 12 protects the oil pressure of the vertical jack 4 to ensure that all vertical jacks 4 maintain normal pressure and will not cause component deformation or dangerous accidents due to overpressure of nearby jacks caused by pressure loss at a certain point. The displacement sensor 10 and pressure sensor 9 corresponding to the vertical jack 4 monitor its working status at all times and transmit it back to the main control console 1 in real time. The main control console 1 judges whether it is normal. If the data is abnormal, an alarm is triggered and the equipment is suspended. After the equipment personnel check and repair, the equipment continues to work. After the vertical jack 4 lifts the component to the steel plate 11 of the walking machine 3 and then stops, the walking machine 3 is independently controlled to horizontally lift and drive the slipper 33 back to the starting point. Then, the vertical jack 4 is independently controlled to lower the component onto the steel plate 11 of the walking machine 3 and continue the jacking stage.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these will not affect the implementation effect of this utility model or the practicality of the patent.
