[0007] A traction mechanism comprises a jack device and a pull rod, the jack device is arranged at the rear end of the bottom longitudinal beam, one end of the pull rod is detachably connected with the front support, and the other end is connected with the jack device;
[0008] A main jack is detachably arranged between the bridge deck and the bottom longitudinal beam;
[0009] A hanging basket body is hung on the front end of the main truss.
[0010] The utility model discloses a trackless hanging basket structure, which comprises:
[0011] In some embodiments, the bottom longitudinal beam comprises double-spliced I-beams. The double-spliced I-beams have high strength, so that the bottom longitudinal beam has high strength and is not easy to deform.
[0012] In some embodiments, the front support comprises a load-bearing base and a load-bearing drum.
[0013] The load-bearing base is placed on the bridge deck, and two load-bearing rollers are coaxially arranged on the load-bearing base and used to roll with the two flange plates of the double-spliced I-beam. During the use of the hanging basket, the front support is pressed because the hanging basket body is hung at the front end of the bottom longitudinal beam. Therefore, the load-bearing rollers bear the pressure of the bottom longitudinal beam and enable the bottom longitudinal beam to slide on the front support through the load-bearing rollers.
[0014] In some embodiments, the front support further comprises sliding rollers, the top of the load-bearing base is provided with baffles on both sides, and two sliding rollers are rotatably arranged on the opposite sides of the baffles, respectively. The two sliding rollers are above the load-bearing rollers and are used to roll with the flanges of the double-spliced I-beam. Before the main truss walks, the front support needs to be moved. Therefore, the front support is moved by sliding on the bottom longitudinal beam through the sliding rollers.
[0015] In some embodiments, the tread of the sliding roller is tapered. The tread of the sliding roller is tapered to ensure that the sliding roller completely fits the flange of the double-spliced I-beam.

[0017] In some embodiments, the ear plates on both sides of the reverse buckle base are rotatably connected to the reverse buckle base by a pin shaft. When multiple reverse buckle rollers are arranged on a single ear plate, in order to ensure that the multiple reverse buckle rollers are in full contact with the flanges of the double-spliced I-beam, the ear plate is rotatably connected to the reverse buckle base, so that the ear plate can rotate relative to the reverse buckle base, and the multiple reverse buckle rollers on the single ear plate are in contact with the flanges of the double-spliced I-beam.
[0018] In some embodiments, a carrying beam is arranged on the reverse buckle base, the two ends of the carrying beam extend out of the two sides of the reverse buckle base, and the two ends of the carrying beam are detachably anchored to the bridge deck. When the main truss needs to walk, the anchor between the rear end of the bottom longitudinal beam and the bridge deck is released, and the load of the rear end of the bottom longitudinal beam is completely applied to the rear support. In order to ensure that the rear support reversely buckles the rear end of the bottom longitudinal beam on the bridge deck, the reverse buckle base is anchored to the bridge deck by the carrying beam.
[0019] In some embodiments, the tread of the reverse buckle roller is tapered. The tread of the reverse buckle roller is tapered to ensure that the tread of the reverse buckle roller is in full contact with the flanges of the double-spliced I-beam.

[0035] A bottom longitudinal beam 11 is provided at the bottom of the main truss 1, and the rear end of the bottom longitudinal beam 11 is detachably anchored to the bridge deck;
[0036] The front support 2 and the rear support 3 are both detachably arranged on the bridge deck, and the front support 2 and the rear support 3 are both slidably connected to the bottom longitudinal beam 11, and the front support 2 is located in front of the rear support 3;

[0038] The main jack 5 is detachably arranged between the bridge deck and the bottom longitudinal beam 11;
[0039] The hanging basket body 6 is hung at the front end of the main truss 1 .
[0040] Specifically, in this embodiment, the main truss 1 also includes a vertical beam 12, which is vertically arranged on the top of the bottom longitudinal beam 11. The vertical top is connected to two diagonal straps 13, and the bottom ends of the two diagonal straps 13 are respectively connected to the front end and the rear end of the bottom longitudinal beam 11.
[0041] In this embodiment, the rear end of the bottom longitudinal beam 11 is detachably anchored to the bridge deck through the fine-rolled threaded steel bars pre-embedded in the bridge deck and the fine-rolled nuts, the front support 2 is placed on the bridge deck, the rear support 3 is detachably anchored to the bridge deck through the fine-rolled threaded steel bars pre-embedded in the bridge deck and the fine-rolled nuts, and the main jack 5 is placed on the bridge deck.
[0042] The working principle of this embodiment is as follows:Figure 1 As shown, when the hanging basket is in use, the top of the main jack 5 does not abut against the bottom longitudinal beam 11, the rear end of the bottom longitudinal beam 11 is anchored to the bridge deck, and the rear support 3 is in a state of disengagement from the bridge deck. Figure 6 As shown, when the construction of the next segment of the bridge is completed and the hanging basket needs to be moved forward to the next segment, the bottom longitudinal beam 11 is first lifted by the main jack 5, so that the bottom longitudinal beam 11 is lifted by 2-3 cm. At this time, the bottom longitudinal beam 11 lifts the front support 2 and the rear support 3 to disengage from the bridge deck. At this time, the front support 2 and the rear support 3 are moved to the next segment by sliding the front support 2 and the rear support 3. Figure 7 As shown, at this time, the main jack 5 is unloaded, the bottom longitudinal beam 11 is lowered, and the front support 2 and the rear support 3 re-contact the bridge deck. Then, the rear support 3 is anchored to the bridge deck, and the rear end of the bottom longitudinal beam 11 is disengaged from the bridge deck. At this time, since the bottom longitudinal beam 11 is slidably connected to the front support 2 and the rear support 3, the bottom longitudinal beam 11 can slide forward and backward relative to the front support 2 and the rear support 3. At this time, the jack mechanism in the traction mechanism is activated, the jack mechanism tensioning the rod 42 pushes the rear end of the bottom longitudinal beam 11 towards the front support 2, so that the main truss 1 walks forward, and the main truss 1 walks to the next segment. Figure 8 As shown, when the main truss 1 is in place, the rear end of the bottom longitudinal beam 11 is re-anchored to the bridge deck, and the anchor connection between the rear support 3 and the bridge deck is disengaged, completing the walking of the main truss 1.
