Technical Field

The invention relates to the technical field of building construction, in particular to a movable working platform for chimney dismantling construction.

Background

In the process of city transformation, along with the migration of factories and mines from a city area to a remote area, the original structures such as a chimney and the like are not used any longer and need to be dismantled. However, the existing dismounting device has a complex structure, is inconvenient to operate, is unsafe, and cannot meet the requirements of operators.

Disclosure of Invention

In view of the above, the invention provides a movable working platform for chimney demolition construction, which has the following specific technical scheme:

a movable working platform for chimney demolition construction comprises a single hoop and a derrick mast, wherein the single hoop is arranged on the outer wall of a chimney in an arc shape, and the derrick mast is arranged on the single hoop through a hook;

bolt holes are formed in the two sides of the single hoop and used for connecting the two single hoops through high-strength bolts, and a plurality of hanging holes are formed in the outer wall of each single hoop at equal intervals and used for hanging the gin pole;

the derrick mast comprises a flat plate, a tripod arranged below the flat plate and a guardrail placed in the groove;

the two sides below the guardrail can be detachably arranged in the cylindrical grooves on the two sides of the upper surface of the flat plate

Further, the inner diameter of the groove is larger than the outer diameter of the guardrail.

Furthermore, the single-piece hoop is formed by welding 100 × 10 flat steel and 80 × 8 angle iron.

Furthermore, the hook is L-shaped, the hanging hole is penetrated through the lower part of the hook, and the nut is arranged below the hanging hole for fixation, so that the hook is prevented from being unhooked in the lifting process to enable the derrick mast to fall off to cause danger.

By adopting the technical scheme, the method has the following beneficial effects:

the chimney dismantling device is simple in integral structure and convenient to use and dismantle, reduces the difficulty of chimney dismantling, and meets the use requirements of constructors.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example 1: the movable working platform for chimney demolition construction shown in fig. 1-3 comprises a single hoop 1 and a derrick mast 2, wherein the single hoop 1 is arc-shaped and arranged on the outer wall of the chimney, and the derrick mast 2 is arranged on the single hoop 1 through a hook 24; the derrick mast 2 is hung along the circumferential direction of the hoop through the hook 24;

bolt holes 11 are formed in two sides of the single hoop 1 and used for connecting the two single hoops 1 through high-strength bolts, and a plurality of hanging holes 12 are formed in the outer wall of each single hoop 1 at equal intervals and used for hanging the gin pole 2;

the derrick mast 2 comprises a flat plate 22, a tripod 21 arranged below the flat plate 22 and a guardrail 23 placed in the groove 25;

the two sides below the guardrail 23 can be detachably arranged in the cylindrical grooves 25 on the two sides of the upper surface of the flat plate 22

The inner diameter of the groove 25 is larger than the outer diameter of the guard rail 23.

The single-piece hoop 1 is formed by welding 100 × 10 flat steel and 80 × 8 angle iron.

The hook 24 is L-shaped, the hanging hole 12 is penetrated below the hook 24, and the nut is arranged below the hanging hole 12 for fixation, so that the hook 24 is prevented from being unhooked in the lifting process to enable the derrick mast 2 to fall and cause danger.

When the invention is used for specifically removing the chimney, a constructor directly reaches the top opening of the chimney through a steel ladder stand of the chimney which is inspected and repaired, the manufactured single-sheet hoop 1 is hoisted to the top opening of the concrete chimney through a vertical transportation system, the hoops of a movable platform are assembled along the circle of the outer wall of the chimney, the single-sheet hoop 1 and the single-sheet hoop 1 are connected through high-strength bolts with phi 22, after the hoops are connected and assembled, the constructor reaches the top opening of the chimney to hang safety belts, a circle of phi 12 steel wire ropes 3 is surrounded along the lower part of the outer wall of the top opening of the chimney, the steel wire ropes 3 which are tightened by three chucks are clamped, the steel wire ropes 3 which surround the circle of the chimney are divided into a plurality of equal parts according to the circumference of the chimney, each 2 m equal part is provided with a lifting point, a phi 20S buckle is hung on each S buckle, a manual hoist is hung on each S buckle, the manual hoist is connected with each single-sheet 1, after connection, and (3) tightening the broken part of the hoop, hanging the manufactured derrick mast 2 to the top opening of the chimney by constructors, and connecting and installing the hook 24 by using a phi 16 hook 24 welded at two sides of the derrick mast 2 and the hoop.

After the whole installation is finished, constructors buckle the safety belt, the safety belt is hung on the steel wire rope 3 surrounding the circle of the chimney in a high mode, the hand-operated block is pulled to enable the whole movable platform to be lifted to the specified position of the top opening of the chimney, and the anchor ear notch is connected and screwed down through a phi 22 reinforcing bolt. And after the whole movable platform is installed, the constructor removes the wall of the chimney. When constructor constructs, the safety belt is hung on the wire rope 3 of enclosing the chimney round on construction platform, constructor demolishs one section to the reinforced concrete chimney, when demolising construction platform department, slowly loosen the reinforcing bolt of staple bolt butt joint department, slowly put down the chain guide again, the staple bolt of chimney round around the construction platform, work platform's self weight, rethread hand-pull calabash 4 slowly moves down, will tighten up the chain guide of chimney reinforcing bar and work platform at last, just can normally demolish work. Because the upper part of the outer cylinder wall of the chimney is small and the lower part is large, the diameter of the upper part is small, and the diameter of the lower part is large, when a certain section is constructed, the hoop and the derrick mast 2 of the section are added.

The chimney dismantling device is simple in integral structure and convenient to use and dismantle, reduces the difficulty of chimney dismantling, and meets the use requirements of constructors.

Having thus described the basic principles and principal features of the invention, it will be appreciated by those skilled in the art that the invention is not limited by the embodiments described above, which are given by way of illustration only, but that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
