The operation is repeated, and only a very short first oil cylinder 23 can drive the body 1 to move a very long distance. When the body 1 needs to be pulled to separate from the bridge pier, the operation is reversed to pull the body 1 by the first oil cylinder 23.

[0053] Further, when the body 1 needs to be pushed to the pier, the first pushing block 124 is driven to move, the first pushing block 124 blocks the lower half of the through hole on the guide block 12, so that the lower row of pin blocks 211 in the movable block 21 cannot be inserted into the guide block 12, at this time, the extension end of the first oil cylinder 23 is elongated, the upper row of pin blocks 211 in the movable block 21 are inserted into the through hole on the guide block 12, the first oil cylinder 23 pushes the body 1 through the pin blocks 211, when the extension end of the first oil cylinder 23 is shortened, the slope on the pin block 211 abuts against the guide block 12 and is retracted into the movable block 21, at this time, the movable block 21 is separated from the guide block 12, and the movable block 21 can move freely, the extension end of the first oil cylinder 23 is repeatedly elongated, the pin blocks 211 are inserted into the guide block 12 under the pushing of the third spring 212, and the first oil cylinder 23 can continue to push the body 1; when the body 1 needs to be pulled away from the pier, the first pushing block 124 and the second pushing block 125 are driven to move, the first pushing block 124 opens the lower half of the through hole on the guide block 12, and the second pushing block 125 blocks the upper half of the through hole on the guide block 12, when the extension end of the first oil cylinder 23 is elongated, the lower row of pin blocks 211 in the movable block 21 are retracted into the movable block 21 under the pushing of the guide block 12, when the extension end of the first oil cylinder 23 is shortened, the pin blocks 211 are inserted into the guide block 12 under the pushing of the third spring 212, and the first oil cylinder 23 pulls the body 1 to move away from the pier.

[0055] Specifically, when the direction in which the body 1 is moved by the first oil cylinder 23 needs to be switched, the toothed rod 123 is rotated, the toothed rod 123 drives the first toothed plate 121 and the second toothed plate 122 to move, and then the first pushing block 124 opens the lower half of the through hole on the guide block 12, and the second pushing block 125 blocks the upper half of the through hole on the guide block 12, or the first pushing block 124 blocks the lower half of the through hole on the guide block 12, and the second pushing block 125 opens the upper half of the through hole on the guide block 12, so as to switch the direction in which the body 1 is moved by the first oil cylinder 23.

[0057] Specifically, when the first oil cylinder 23 moves the body 1 to the position farthest from the pier, the first wedge block 112 on the main beam 2 is inserted into the guide block 12 and abuts against the slope of the first tooth plate 121, so that the first tooth plate 121 is moved, the first tooth plate 121 drives the second tooth plate 122 to move through the tooth rod 123, and then the first push block 124 blocks the lower half of the through hole of the guide block 12, and the second push block 125 opens the upper half of the through hole of the guide block 12, so as to switch the moving direction of the first oil cylinder 23 with the body 1.

[0058] As further provided in another embodiment of the application, the body 1 is movably provided with a second wedge block 113, two slopes are symmetrically arranged on the second wedge block 113, a slope surface is arranged on the second tooth plate 122, and the second wedge block 113 is fixedly installed with a supporting plate 111.

[0059] Specifically, the first spring 114 is arranged between the second wedge block 113 and the body 1.

[0060] Further, when the first oil cylinder 23 moves the body 1 and moves the two bodies 1 close to each other, the second wedge block 113 on one of the bodies 1 is pushed by the other body 1 to move, the two slopes on the second wedge block 113 push the two second tooth plates 122 inside the two bodies 1 respectively, so that the second tooth plates 122 are moved, the second tooth plates 122 drive the first tooth plate 121 to move through the tooth rod 123, and then the first push block 124 opens the lower half of the through hole of the guide block 12, and the second push block 125 blocks the upper half of the through hole of the guide block 12, so as to switch the moving direction of the first oil cylinder 23 with the body 1. At the same time that the second wedge block 113 moves, the supporting plate 111 is driven to move, the supporting plate 111 no longer supports the fixing pin 11, and the fixing pin 11 is inserted into the two connecting blocks 13 to fix the two bodies 1 together.

[0061] As further provided in another embodiment of the application, the main beam 2 is symmetrically provided with a limiting block 22, the fourth spring 221 and the second pull rope 224 are arranged between the two limiting blocks 22 respectively, the movable rod 222 is movably arranged on one of the limiting blocks 22, the fifth spring 223 is arranged between the movable rod 222 and the limiting block 22, the lifting block 32 is movably arranged on the main beam 2, the lifting block 32 is specifically in the shape of C, the bottom of the inner side of the lifting block 32 is provided with a protruding block, the main beam 2 is provided with a plurality of recesses matched with the protruding block, and the lifting block 32 is matched with the protruding block.

[0062] Specifically, when the bridge deck is constructed, the supporting legs and the cross beams 3 are sequentially installed on the piers, the two main beams 2 are symmetrically installed on the cross beams 3, and the two bodies 1 are respectively installed on the two main beams 2.

[0063] At this time, the first pushing block 124 blocks the lower half of the through hole on the guide block 12, and the second pushing block 125 opens the upper half of the through hole of the guide block 12. The first oil cylinder 23 works, so that the lower row of pin blocks 211 inside the movable block 21 cannot be inserted into the guide block 12. The first oil cylinder 23 is elongated, and the upper row of pin blocks 211 inside the movable block 21 are inserted into the through hole on the guide block 12. The first oil cylinder 23 pushes the body 1 through the pin blocks 211. When the first oil cylinder 23 is shortened, the slope on the pin block 211 abuts against the guide block 12 and is retracted into the movable block 21. At this time, the movable block 21 is separated from the guide block 12, and the movable block 21 can move freely. The first oil cylinder 23 is repeatedly elongated, and the pin blocks 211 are inserted into the guide block 12 under the pushing of the third spring 212. The first oil cylinder 23 can continue to push the body 1. Only a very short first oil cylinder 23 can push the body 1 to move a very long distance;

[0064] When the body 1 approaches the pier, the gear 144 is pushed by the rack 145, the gear 144 rotates, and the take-up reel winds up the first pull rope 143. The first pull rope 143 pulls the pushing rod 141, and the pushing rod 141 moves towards the inside of the sliding rod 14 and compresses the second spring 142. The pushing rod 141 moves away from the connecting block 13.

[0065] When the body 1 approaches the pier, the groove on the body 1 pushes the movable rod 222 to move. The movable rod 222 pulls one of the limiting blocks 22 through the fifth spring 223, so that the limiting block 22 is retracted into the main beam 2. The limiting block 22 moves another limiting block 22 through the second pull rope 224, so that the other limiting block 22 is also retracted into the main beam 2. The fifth spring 223 can provide enough space for the movable rod 222 to move relative to the limiting block 22.

[0066] When the two bodies 1 approach each other, the second wedge block 113 on one of the bodies 1 is pushed by the other body 1 to move. The two slopes on the second wedge block 113 push the two second tooth plates 122 inside the two bodies 1 respectively, so that the second tooth plates 122 move. The second tooth plates 122 move the first tooth plate 121 through the tooth rod 123, and then the first pushing block 124 opens the lower half of the through hole on the guide block 12. The second pushing block 125 blocks the upper half of the through hole of the guide block 12. The first oil cylinder 23 changes the direction of movement of the body 1. While the second wedge block 113 moves, the supporting plate 111 moves, and the fixed pin 11 is no longer supported by the supporting plate 111. The fixed pin 11 is inserted into the two connecting blocks 13, and the two bodies 1 are fixed together.

[0067] At this time, the second oil cylinder 31 is elongated, and the protrusion on the lifting block 32 is embedded in the groove on the main beam 2. The second oil cylinder 31 lifts the main beam 2 together with the body 1, so that the internal space of the two bodies 1 is located above the pier. At this time, the bridge deck can be built in the mold composed of the two bodies 1.

[0068] After the bridge deck is built, the second oil cylinder 31 is shortened, the body 1 falls, and the bridge deck is placed on the pier. The body 1 continues to move downward and is separated from the bridge deck. At this time, the damping telescopic rod 146 abuts against the cross beam 3 and drives the rack 145 to move upward. The rack 145 is separated from the gear 144, the gear 144 is no longer locked, the second spring 142 pushes the abutting rod 141 to move upward, the abutting rod 141 abuts against the fixed pin 11, and the fixed pin 11 is retracted into the upper connecting block 13.

[0069] At this time, the first oil cylinder 23 works. When the telescopic end of the first oil cylinder 23 is elongated, the lower row of pin blocks 211 in the inner side of the movable block 21 is retracted into the interior of the movable block 21 under the abutment of the guide block 12. When the telescopic end of the first oil cylinder 23 is shortened, the pin blocks 211 are inserted into the guide block 12 under the abutment of the third spring 212. The first oil cylinder 23 pulls the body 1 to move away from the pier.

[0070] When the two bodies 1 are separated, the second wedge block 113 is extended from the body 1 under the abutment of the first spring 114 and drives the supporting plate 111 to move. The supporting plate 111 supports the fixed pin 11 to avoid falling.

[0071] When the body 1 moves away from the pier, the body 1 no longer continues to abut against the fixed movable rod 222. The two limiting blocks 22 are reinserted into the grooves on the cross beam 3 under the abutment of the fourth spring 221.

[0072] When the body 1 moves to the position farthest away from the pier, the first wedge block 112 on the main beam 2 is inserted into the guide block 12 and abuts against the slope of the first tooth plate 121, so that the first tooth plate 121 moves. The first tooth plate 121 drives the second tooth plate 122 to move through the tooth rod 123. Then, the first abutting block 124 blocks the lower half of the through hole of the guide block 12, and the second abutting block 125 opens the upper half of the through hole of the guide block 12, switching the moving direction of the body 1 by the first oil cylinder 23.

[0073] At this time, the telescopic end of the second oil cylinder 31 is elongated, driving the push block 32 to move. The push block 32 drives the main beam 2 to move through the protrusion. The limiting block 22 cooperates with the groove on the cross beam 3 to limit the movement of the main beam 2 in the vertical direction. The main beam 2 moves in the horizontal direction. When the telescopic end of the second oil cylinder 31 is shortened, the push block 32 moves downward first, and the protrusion thereon is separated from the main beam 2. At this time, the push block 32 can slide on the main beam 2. The second oil cylinder 31 repeats the work, driving the main beam 2 to move, and pushing the main beam 2 together with the body 1 thereon to the next working point.

[0074] The foregoing merely illustrates some exemplary embodiments of the application, and no doubt numerous modifications and alterations thereto will be apparent to those skilled in the art. Accordingly, the above description is intended for purposes of illustration only and should not be construed as limiting the scope of the application.
