Description

Technical Field

[0001] This application relates to the technical field of ultra-high-speed and low-vacuum pipeline construction, and particularly relates to an integral lifting jig for binding the steel reinforcement cage of an ultra-high-speed and low-vacuum pipeline. Background Art

[0002] The elevated standard beam of the leading section of the ultra-high-speed and low-vacuum pipeline adopts a combined pipe beam of steel structure + prestressed concrete. The upper part of the pipe beam is an "n"-shaped semi-circular steel pipe cover structure, and the lower part is a combined structure of a "U"-shaped "steel structure + prestressed concrete" laminated structure. The U-shaped beam is designed as a precast full-span pretensioned prestressed concrete simply supported beam.

[0003] When manufacturing the U-shaped beam, the outer steel plate of the U-shaped beam needs to simultaneously serve as the function of the casting bottom formwork. Therefore, during the construction process of the U-shaped beam, it is necessary to first build a support frame before carrying out the steel bar binding operation. After the steel bar project is completed, the entire outer steel plate system needs to be hoisted to the tensioning pedestal for prestress tensioning. After the tensioning is completed, the U-shaped beam also needs to be transported to the beam storage area.

[0004] In view of the above related technologies, after binding the steel bars to the support frame of the U-shaped beam, it is necessary to hoist the entire outer steel plate system to the tensioning pedestal, which is likely to cause structural deformation of the outer steel plate and the bound steel bars of the U-shaped beam during the hoisting process, affecting the final concrete pouring quality.

[0034] Two crossbeams are placed in advance in the buried tension bench. The two crossbeams respectively abut between the first bottom frame 115 and the auxiliary bottom frame 24 and between the second bottom frame 125 and the auxiliary bottom frame 24. Before lifting an integral lifting jig for binding the steel cage of a super-high-speed and low-vacuum pipeline into the buried tension bench, rotate the double-headed screw rod 42 to make the first slider 43 move in the direction of approaching or separating from each other at the same time. While the first slider 43 slides, adjust the position of the second slider 45 correspondingly to make the structure of the first connecting rod 46 stable, and realize the adjustment of the distance between the jig body 1 and the auxiliary frame 2, so that an integral lifting jig for binding the steel cage of a super-high-speed and low-vacuum pipeline can adapt to crossbeams of different sizes.

[0035] Then fixedly connect the second connecting rod 47 with the first main upper chord rod 111 and the auxiliary upper chord rod 21, and the second main upper chord rod 121 and the auxiliary upper chord rod 21 respectively, improve the structural stability between the jig body 1 and the auxiliary frame 2, and further improve the structural stability of an integral lifting jig for binding the steel cage of a super-high-speed and low-vacuum pipeline.

The ends of no less than two first screws 31 away from the second main support rod 123 are evenly and fixedly installed on the support pipe 32. The first threaded sleeves 311 are evenly and rotatably installed in the second main support rod 123. The first screws 31 are inserted and threadedly connected to the first threaded sleeves 311.

The synchronous toothed belt 331 is wound around the first spur gear 33 and the second spur gear 332. Both the first spur gear 33 and the second spur gear 332 are engaged with the synchronous toothed belt 331.

[0038] The rotating shaft 34 is coaxially and fixedly connected to the second spur gear 332. The third spur gear 35 is coaxially sleeved and rotatably installed on the rotating shaft 34. An internal ratchet 351 is coaxially and fixedly installed on the third spur gear 35. Two sliding rods 341 are inserted and slidably installed on the rotating shaft 34. The ends of the sliding rods 341 away from each other are fixedly connected with abutting blocks 342. The abutting blocks 342 abut against the internal ratchet 351. The abutting blocks 342 are in the shape of a triangular prism. The ends of the two sliding rods 341 close to each other are fixedly connected with a first return spring 343. The first return spring 343 always moves the two sliding rods 341 in the direction away from each other. One end of the sliding lead screw 36 is inserted and rotatably installed at one end of the second main lower chord 122. The other end of the sliding lead screw 36 is inserted into another adjacent second main lower chord 122.

The other end of the sliding lead screw 36 is coaxially and fixedly connected with a second face gear 362. The second face gear 362 is rotatably installed in the second main lower chord 122. The first face gear 361 can be engaged with the second face gear 362 in another adjacent second main lower chord 122.

[0039] When connecting two adjacent second tire racks 12, the sliding lead screw 36 is inserted into the second main lower chord 122. The sliding lead screw 36 meshes with the third spur gear 35 of the adjacent column assembly 3 and drives the third spur gear 35 to rotate forward. The third spur gear 35 rotates and then drives the internal ratchet 351 to rotate. While the internal ratchet 351 rotates, it relatively slides with the two abutting blocks 342, so that the third spur gear 35 rotates relative to the rotating shaft 34. Until the first face gear 361 is engaged with the second face gear 362 of the adjacent column assembly 3.

[0040] When adjusting the upright column assembly 3, one of the second end face gears 362 is driven to rotate by the driving assembly 5. The rotation of the second end face gear 362 drives the first end face gear 361 to rotate. The rotation of the first end face gear 361 drives the sliding lead screw 36 to rotate. The rotation of the sliding lead screw 36 drives the third straight gear 35 to rotate in the reverse direction. The rotation of the third straight gear 35 drives the internal ratchet 351 to rotate. While the internal ratchet 351 rotates, it abuts against the two abutting blocks 342. The rotation of the internal ratchet 351 drives the two abutting blocks 342 to rotate synchronously around the axis of the rotating shaft 34. The rotation of the abutting block 342 drives the sliding rod 341 to rotate synchronously. The synchronous rotation of the sliding rod 341 drives the rotating shaft 34 to rotate synchronously. The rotation of the rotating shaft 34 drives the second straight gear 332 to rotate. The rotation of the second straight gear 332 drives the synchronous toothed belt 331 to move. The movement of the synchronous toothed belt 331 drives the first straight gear 33 to rotate. The rotation of the first straight gear 33 drives the first threaded sleeve 311 to rotate. The first threaded sleeve 311 rotates relative to the first screw rod 31. As a result, a relative displacement occurs between the first threaded sleeve 311 and the first screw rod 31 in the axial direction. The first screw rod 31 moves in the direction away from the first threaded sleeve 311. The movement of the first screw rod 31 drives the support pipe 32 to move towards the outer steel plate side plate of the U-shaped beam and abut against the outer steel plate side plate of the U-shaped beam, making the outer steel plate side plate of the U-shaped beam perpendicular.

[0041] Meanwhile, under the action of the two side upright column assemblies 3, the outer steel plate of the U-shaped beam is clamped, improving the installation stability of the outer steel plate of the U-shaped beam on the jig body 1.

[0054] The implementation principle of an integral lifting jig for binding steel cages of ultra-high-speed and low-vacuum pipelines in an embodiment of the present application is as follows: The outer steel plate of the U-shaped beam is lifted into the main body 1 of the jig, and the column assembly 3 is adjusted so that the column assembly 3 abuts against the outer steel plate of the U-shaped beam and makes the outer steel plate of the U-shaped beam vertical, thereby improving the structural stability of the outer steel plate of the U-shaped beam. Then, the staff carry out the work of binding steel bars and threading prestressed steel strands on the outer steel plate of the U-shaped beam. After the work of binding steel bars and threading prestressed steel strands is completed, the integral lifting jig for binding steel cages of ultra-high-speed and low-vacuum pipelines, the outer steel plate of the U-shaped beam, the bound steel bars, and the prestressed steel strands are integrally lifted into the buried tensioning pedestal. Two cross beams are placed in the buried tensioning pedestal in advance, and the two cross beams are located between the main body 1 of the jig and the auxiliary frame 2. Then, work such as prestressed steel strand tensioning, formwork installation, concrete pouring, and curing is carried out. After that, the auxiliary frame 2 and the connecting component 4 are removed, and the U-shaped beam is lifted by the cross beam. After the U-shaped beam is lifted out, the auxiliary frame 2 and the connecting component 4 are reinstalled, and the integral lifting jig for binding steel cages of ultra-high-speed and low-vacuum pipelines is integrally lifted out for subsequent reuse. By using the integral lifting jig for binding steel cages of ultra-high-speed and low-vacuum pipelines to integrally lift out the outer steel plate and steel bars of the U-shaped beam support frame, the structural stability of the outer steel plate and steel bars of the U-shaped beam support frame during lifting is improved, and the concrete pouring quality of the U-shaped beam is improved.
