Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to a Bailey frame simple dismantling system. Background Art

[0002] Reinforced concrete silos are widely used to store grain, cement and other materials. As an important type of reinforced concrete silo, shallow silos are widely used because of their small footprint, large storage capacity, high degree of mechanization and automation. In recent years, a large number of grain storage projects mainly based on shallow silos have been newly built in various places.

[0003] The wall of the shallow circular silo is constructed with slipforms. After the slipform construction is completed and the slipform equipment is removed, the silo roof construction is carried out. The silo roof structure construction uses a large number of Bailey frame steel platform support systems, that is, the air support steel platform is constructed through the central lattice column + Bailey truss. Then the formwork of the dome structure is set up on the air support platform. After the dome structure construction is completed, the formwork is removed and the air support steel platform needs to be removed.

[0004] The traditional practice is to reserve holes on the dome structure corresponding to the hanging points of each Bailey frame for threading the wire ropes; then set up fixed supports on the conical shell roof, and use a winch or electric hoist to dismantle the Bailey frame one by one.

[0005] The traditional method requires a large number of holes to be reserved for the wire ropes, which is usually 1 or 2 times the number of Bailey frames. A large number of small holes need to be repaired twice, and the shallow silo, as a grain storage building, has extremely high requirements for waterproofing and must achieve zero leakage. In principle, no holes or construction joints are left on the dome structure.

The first lifting assembly is used for For lifting the Bailey frame 200; a second lifting component, which includes a second lifting rope 42, the second lifting rope 42 is passed through the grain inlet 12 and is connected to a Bailey frame 200, and the second lifting component is used to lift the Bailey frame 200; the first lifting component is slidably connected to the annular wire rope 5, and multiple Bailey frames 200 are arranged at intervals along the circumferential direction of the shallow silo dome 100. The first lifting component and the second lifting component are used in combination to remove multiple Bailey frames 200 one by one.

[0046] It should be noted that the plurality of Bailey frames 200 are arranged at intervals along the axial direction of the silo dome 100. The first lifting assembly can slide along the annular wire rope 5 to the top of any one of the plurality of Bailey frames 200 to cooperate with the second lifting assembly to remove the Bailey frame 200.

[0047] In the above arrangement, after the first lifting assembly cooperates with the second lifting assembly to dismantle a Bailey frame, the first lifting assembly can be moved to the top of the next Bailey frame by traction or the like. The first lifting assembly cooperates with the second lifting assembly to dismantle the next Bailey frame until all the Bailey frames 200 are dismantled. In this way, the existing designed openings, i.e., the circulating fan opening 11 and the grain inlet 12, are fully utilized. There is no need to reserve openings or make secondary holes on the shallow silo dome 100, which results in little damage to its structure and little leakage risk. This improves the overall structural strength of the shallow silo dome 100.

[0048] Specifically, Figures 1 to 4 As shown, in one embodiment, the first lifting assembly includes a first pulley fixed support 81, a first pulley 21, a first hoist 31 and a steering mechanism. The first pulley 21 is arranged on the first pulley fixed support 81; the first hoist 31 is arranged on the support platform 10; the steering mechanism is connected to the lattice column 9 at one end, and the other end of the steering mechanism is slidably connected to the annular wire rope 5; one end of the first suspension rope 41 is connected to the first hoist 31, and the other end of the first suspension rope 41 is wound around the first pulley 21 and the steering mechanism, and is connected to one of the multiple Bailey frames 200.

[0049] It should be noted that, by sliding the steering mechanism on the circular steel wire rope 5, it can be ensured that the first lifting assembly slides to the top of the Bailey frame 200 to be removed.

[0050] Specifically, Figures 1 to 4 As shown, in one embodiment, the steering mechanism includes a second pulley 22, a tie assembly and a third pulley 23. The second pulley 22 is hung on the hoop wire rope 5 and is slidably connected to the hoop wire rope 5; the tie assembly is arranged on the lattice column 9; the third pulley 23 is hung on the tie assembly; the other end of the first suspension rope 41 is wound around the first pulley 21, the second pulley 22 and the third pulley 23, and is connected to one of the multiple Bailey frames 200.

The second pulley 22 is hung on the hoop wire rope. The hoop wire rope is sagged and tightened by the gravity of the second pulley 22 and the force applied to the pulley during removal, so that the second pulley 22 will not slide arbitrarily during removal. When the next Bailey frame needs to be removed, the second pulley 22 hung on the hoop wire rope 5 is slid to the top of the next Bailey frame to be removed. The head and tail of the hoop wire rope 5 pass through The connecting point is set at the position of the grain condition detection door of the shallow circular silo, which is convenient for the subsequent recovery of the circular wire rope.

[0061] After the pulley fixing support (first and second pulley fixing support) is fixed, the pulleys (first and third pulleys) are hung, the annular wire rope is set, and the second pulley hung thereon is hung; after the first and second winches are fixed. The suspension rope (first and second suspension rope) passes through the first and second winches around the corresponding pulleys, and finally, the ends of the suspension ropes are firmly fixed (tied and fixed) to the Bailey frame suspension points.

[0062] It should be noted that the suspension rope is Steel core wire rope.

[0063] Then, two winches are used to lift the steel truss (the Bailey frame to be dismantled) away from the lattice columns and the brackets on the warehouse wall.
