[0031] Example 2

[0032] The demolition process of the novel aerial demolition machine described in Example 1 is as follows.

[0033] Step 1: Use an external crane to install the aerial demolition machine on the first floor of the building to be demolished, including truss beams 1, crane moving tracks 2, cutting machine moving tracks 3, standard sections 4, purlins 5, gantry crane 6, and high-pressure water gun cutting machine 7.

[0034] Step 2: Start raising the height of the lifting column. Through the hydraulic pump station, control the telescopic rods of the six groups of hydraulic cylinders 8 to extend at the same time. The standard section 4 connected to the telescopic rod is raised to the preset height. The standard section 4 is increased horizontally to complete one lifting. Repeat the lifting until the truss beam 1, the crane moving track 2, and the cutting machine moving track 3 reach the top building height of the building to be demolished.

[0035] Step 3: Start dismantling the top floor building and divide the floor into blocks of 3m×3m in size. The high-pressure water gun cutting machine 7 arranged vertically and horizontally moves along the cutting machine moving track 3 to the first block at the edge of the floor, and cuts two circular holes with a diameter of about 20cm in the middle part of the first block.

[0036] Step 4: Move the high-pressure water gun cutting machines 7 arranged vertically and horizontally to both sides along the cutting machine moving track 3, move the gantry crane 6 to above the circular hole, and fix the hook of the gantry crane 6 to the floor slab through the hole. The gantry crane 6 pre-tensions the floor slab to achieve a pre-tightening effect.

[0037] Step 5: Cut the floor slab using high-pressure water gun cutting machines 7 in both vertical and horizontal directions. After cutting, the gantry crane 6 is suspended and the floor slab is lowered to the ground by moving the gantry crane 6 to the space between the building to be demolished and the lifting columns.

[0038] Step 6: Repeat steps 3 to 5 to complete the demolition of the entire floor. 2 The floor slabs (within 1000 square meters) do not need to be divided into blocks, but can be cut as a whole and lowered to the ground by the gantry crane 6.

[0039] Step 7: After the floor slab is dismantled and hoisted, the middle of the longitudinal beam or transverse beam and the 1 / 4 distance from the end on both sides are cut and punched by the high-pressure water gun cutting machine 7 arranged longitudinally and transversely. The gantry crane 6 is moved to the middle part of the beam, and the hook of the gantry crane 6 is passed through the hole to tie and fix the beam. After tying, the beam is pre-tensioned.

[0040] Step 8: Move the high-pressure water gun cutting machine 7 arranged longitudinally and transversely to the connection between the longitudinal beam column or the transverse beam column to cut, and after cutting, the beam column is lowered to the ground by the gantry crane 6.

[0041] Step nine: Use the vertically arranged high-pressure water gun cutting machine 7 to make holes in the wall, pass the hook of the gantry crane 6 through the hole, apply pre-tension, and then cut. After cutting, use the gantry crane 6 to lower it to the ground.

[0042] Step 10: After the wall is demolished, use the vertically installed high-pressure water gun cutting machine 7 to cut and punch holes in the middle of the vertical beam column and 1 / 4 of the distance from the end on both sides, move the gantry crane 6 to the middle part of the beam column, and pass the hook of the gantry crane 6 through the hole to tie and fix the beam column, and then pre-tension the beam column after tying.

[0043] Step 11: Move the vertically arranged high-pressure water gun cutting machine 7 to the connection point of the vertical beam column and cut it. After cutting, the beam column is lowered to the ground by the gantry crane 6 to complete the demolition of the top floor building.

[0044] Step 12: Start lowering the height of the lifting column. Through the hydraulic pump station, control the telescopic rods of the six groups of hydraulic cylinders 8 to extend at the same time. Lift the standard section 4 connected to the telescopic rod to the preset height. Remove the standard section 4 below the standard section 4 connected to the hydraulic cylinder 8. The demolition height is the floor height of the building to be demolished. At the same time, control the telescopic rods of the six groups of hydraulic cylinders 8 to retract, reconnect the standard section 4, and the truss beam 1, the crane moving track 2, and the cutting machine moving track 3 reach the height of the lower building. Demolish the next floor of the building according to steps 3 to 11.

[0045] Step 13: After the first floor of the building is demolished and the lifting column is lowered to the lowest height, the various components of the aerial demolition machine are dismantled using an external crane.

[0046] In step 2, each lifting requires the hydraulic synchronizer to accurately and synchronously control the extension of all hydraulic cylinders 8. The lifting height is the floor height of the building to be demolished, which is an integer multiple of the length of the standard section 4.

[0047] In step three, the high-pressure water gun cutting machine 7 is used to penetrate wide columns and thick walls. The purpose of cutting holes is to facilitate the lifting of floor slabs, walls and beams.

[0048] In steps 8 and 11, the connection between beams and columns refers to the concrete cast-in-place portion during the assembly of prefabricated beam components. After cutting, the entire beam and column can be hung down.

[0049] In step 12, each descent requires the hydraulic synchronizer to precisely and synchronously control the contraction amount of all hydraulic cylinders 8. The descent height is the floor height of the building to be demolished, which is an integer multiple of the length of the standard section 4.
