In the use process, to avoid dust falling and affecting the normal movement of the equipment, through holes are formed in the bottom of the sliding frame, so that the dust falls to the lower side. When not in use, the fourth hydraulic rod is retracted to realize the storage of the sliding frame in the longitudinal frame, thereby achieving the storage purpose.

Once the pressure sensor on the outer side of the rotating cylinder is pressed too hard, it indicates that the steel truss beam has a tendency to deviate, which needs to be adjusted immediately to avoid damage to the rotating cylinder. The offset detection module is moved by starting the moving module to achieve the purpose of relaxing the rotating cylinder;

[0035] Meanwhile, to ensure the stable vertical setting of the rotating cylinder, the reinforcing ring and the reinforcing rod are set to achieve the purpose of reinforcement, and the fixed ring, the sliding rod and the sliding cylinder can realize the stable up-and-down sliding of the rotating cylinder.

DETAILED DESCRIPTION

[0042] Example 1:

[0043] Please refer to Figure 1 The present application provides a technical solution:

[0044] A construction method and device for bridge construction walking type sliding jacking, comprising a walking machine 1, the inside of the walking machine 1 is slidingly connected with a sliding block 2, the front and rear sides of the sliding block 2 are both provided with a support module 3 for supporting the bridge frame, and the outer side of the support module 3 is fixedly connected with the walking machine 1;

[0045] The two sides of the walking machine 1 are both fixedly connected with a sliding frame 4, the other end of the sliding frame 4 is fixedly connected with a second hydraulic rod 5, and the output end of the second hydraulic rod 5 is fixedly connected with a fifth hydraulic rod 8 for jacking up the bridge frame;

[0046] The front side of the walking machine 1 is provided with a control unit 9, the front side of the sliding frame 4 is fixedly connected with a moving module 7, and the inside of the moving module 7 is provided with an offset detection module 6 for detecting the bridge frame.

[0047] The construction method is as follows:

[0048] Step one: first, erect the device above the temporary main piers, and control synchronously by the total control unit;

[0049] Step two: install the bridge frame above the device, and start the support module 3 to make the top of the support module 3 flush with the top of the sliding block 2 and in close contact with the bridge frame;

[0050] Step three: through the fifth hydraulic rod 8 on both sides of the start and push the bridge frame, and then through the second hydraulic rod 5 fifth hydraulic rod 8 movement, realize the bridge frame in the slider 2 under the small range of movement;

[0051] Step four: then the fifth hydraulic rod 8 reset, through the start of the second hydraulic rod 5 to realize the reset of the fifth hydraulic rod 8, ready for the next cycle process;

[0052] Step five: when installing, the moving module 7 provided is used to push the offset detection module 6 outwards, and the outer side of the offset detection module 6 is in close contact with the bridge frame. Once the sensor inside the offset detection module 6 has excessive pressure, it indicates that the bridge frame is tilted, and the control unit 9 starts the alarm. At this time, timely adjustment is needed.

[0053] The walking machine is generally arranged above the concrete main pier. When the slider drives the steel truss to move, the slider moves to one side of the main pier, and the steel truss is vertically downward under the action of the slider, which will generate a large bending moment on the concrete pier at this time. The longitudinal bending resistance of the concrete pier is poor, which affects the stability of the concrete pier. At the same time, the slider directly acts on the bottom steel beam of the steel truss in a local force mode, and the point of action is not the most stable fulcrum in the steel truss. The steel truss is prone to deformation during the jacking process, which affects the quality of the steel beam laying. When the device is used, the support module 3 is started to make the top of the support module 3 flush with the top of the slider 2 and in close contact with the bottom of the steel truss, so as to share the pressure of the slider 2. The fifth hydraulic rod 8 is started and pushes the steel truss, and the second hydraulic rod 5 on both sides is started to drive the fifth hydraulic rod 8 to move. At this time, the steel truss can be pushed to move horizontally. When a cycle of movement is completed, the fifth hydraulic rod 8 and the second hydraulic rod 5 are reset to prepare for the next cycle. Before the steel truss moves, the moving module 7 drives the offset detection module 6 to move outwards, and the outer side of the offset module 6 is in close contact with the outer side of the steel truss and has a certain pressure. If the steel truss deviates during horizontal movement, the pressure value of the offset module 6 exceeds the specified value, a signal is sent to the control unit 9 to control the moving module 7 to move outwards, so as to avoid damage to the offset module 6. At the same time, the horizontal movement of the steel truss is stopped, and the position of the steel truss is adjusted in time. This arrangement can share the pressure of the slider 2 through the support module 3. During the movement of the slider 2, the pressure of the steel truss on the support module 3 and the slider 2 is vertically downward. At this time, it ensures that the concrete pier is uniformly stressed, and the top of the multiple support modules 3 is in contact with the bottom of the steel truss. At this time, multiple fulcrums effectively avoid the deformation of the bottom of the steel truss, ensuring the laying of the steel truss.

[0054] Example 2

[0055] This embodiment is an improvement on example 1, please refer to Figure 1 and Figure 2 Specifically, the support module 3 includes a fixed frame 301 and a first hydraulic rod 302.

The top of the first hydraulic rod 302 is fixedly connected with a sliding plate 303. The top of the sliding plate 303 is fixedly connected with uniformly distributed top rods 304. The other end of the top rod 304 is fixedly connected with a support frame 305. The inner side of the support frame 305 is rotatably connected with a rotating shaft 306. The other end of the rotating shaft 306 is fixedly connected with a support roller 307.

[0056] During the movement of the steel truss, the first hydraulic rod 302 is synchronously started to drive the sliding plate 303 above to move upwards. The sliding plate 303 drives the top rod 304 above to move upwards. The top rod 304 drives the support frame 305 to move upwards. The upper surface of the support roller 307 inside the support frame 305 is in close contact with the bottom of the steel truss girder, achieving the purpose of sharing the pressure of the sliding block 2. Even when the sliding block 2 drives the steel truss girder to move to one side, the support roller 307 arranged can ensure that the device vertically presses the concrete main pier, ensuring the stable use of the concrete main pier.

7. A construction method for a walking-type sliding jacking construction device for bridge construction according to any one of claims 1-6, characterized in that: The construction method is as follows: Step 1: First, the device is erected on top of multiple temporary main piers and synchronously controlled by the central control unit; Step 2: By installing the bridge frame above this device, and by activating the support module (3), the top of the support module (3) is flush with the top of the slider (2) and in close contact with the bridge frame; Step 3: Start and push the bridge frame by the fifth hydraulic rod (8) on both sides, and then drive the fifth hydraulic rod (8) to move by the second hydraulic rod (5), so that the bridge frame can move in a small range under the movement of the slider (2); Step 4: Then the fifth hydraulic rod (8) is reset. The fifth hydraulic rod (8) is reset by starting the second hydraulic rod (5), which prepares for the next cycle process. Step 5: During installation, the movable module (7) is used to push the offset detection module (6) outward, and the outer side of the offset detection module (6) is in close contact with the bridge frame. Once the sensor pressure inside the offset detection module (6) is too high, it indicates that the bridge frame is tilted, and the control unit (9) will start an alarm. At this time, timely adjustment is required.
