The utility model is characterized in that: a rotary hanger is arranged on a torch tower frame through a load bearing device; a fixed pulley and a guide pulley are arranged in the upper part of the hanger; a hook is arranged at one end of the steel wire rope arranged on the fixed pulley and the guide pulley, and the other end is arranged on the hoist; the torch tower frame is also provided with a fixed hanger which is provided with a manual inverted chain at the upper part. The utility model has the advantages of convenient construction, high construction safety, short construction period and low construction cost.
Description
Technical field
The utility model relates to device used in a kind of petrochemical enterprise, especially a kind of tower changing device on first watch of releasing flare.
Background technology
Tower releasing flare is the requisite device of petrochemical enterprise more than 60 meters.Tower structure of releasing flare commonly used is made up of chimney and pylon two parts, and pylon is the triangle steel structure, and chimney comprises cylindrical shell and flare tip.After long-time the use, the burned damage of flare tip must in time be changed.Present domestic replacing flare tip adopts large-scale crane usually, and construction cost is higher, and working security is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of tower changing device on first watch of releasing flare, to improve flare tip replacing safety of construction, reduction construction cost.
The utility model is to realize like this, a kind of tower changing device on first watch of releasing flare, it has and can be installed on the installing flare tower frame by load carrier by rotating suspension bracket, also have slewing equipment to be installed in the suspension bracket outside on the installing flare tower frame, the top of suspension bracket is equipped with fixed pulley and directive wheel, steel wire rope one end of installing on fixed pulley and the directive wheel has suspension hook, the other end to be installed on the hoist engine, and fixedly suspension bracket also is installed on installing flare tower frame, and fixedly the top of suspension bracket is equipped with manual chain hoist.
Adopt the tower changing device on first watch of releasing flare of said structure, easy construction, the working security height, the duration is short, and construction cost is low.

The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model and using method.
As shown in drawings, a kind of tower changing device on first watch of releasing flare of the utility model, it has and can be installed on the installing flare tower frame (10) by load carrier (2) by rotating suspension bracket (6), also have slewing equipment (3) to be installed in the suspension bracket outside on the installing flare tower frame, the top of suspension bracket is equipped with fixed pulley (4) and directive wheel (5), steel wire rope (1) one end of installing on fixed pulley and the directive wheel has suspension hook, the other end to be installed on the hoist engine (20), fixedly suspension bracket (8) also is installed on installing flare tower frame, and fixedly the top of suspension bracket is equipped with manual chain hoist (7).
On described load carrier (2), there is roller (17) to be positioned at the outside of suspension bracket (6), there is roller sleeve (16) outside of roller, has bearing plate (19) to be fixed on the installing flare tower frame (10) below the roller sleeve.Stiffener (18) can be arranged between roller sleeve and bearing plate.
On described slewing equipment (3), roller (12) is positioned at the outside of suspension bracket (6), and there is roller sleeve (11) outside of roller (12), and the outside of roller sleeve has fixed head (14) to be fixed on the installing flare tower frame (10).Stiffener (13) can be arranged between roller sleeve and fixed head, and can there be roller filler ring (15) the following of roller.
The roller lower end is designed to hemispherical, is filled with lubricating grease between each roller sleeve and the suspension bracket (6).
Suspension bracket (6), fixedly suspension bracket (8) is installed on the platform of installing flare tower frame, and hoist engine is installed on the ground.Suspension bracket, fixedly suspension bracket can select for use seamless steel pipe to make.
Suspension centre is selected in the flare tip top above the chimney (9).When carrying out flare tip replacing construction, suspension hook, the suspension hook on the manual chain hoist on the steel wire rope are hung in the flare tip top respectively.The flare tip that will change (comprise flare tip below one section cylindrical shell) is pulled down from chimney earlier, and its action by hoist engine is winched to ground.Then, with new flare tip (comprise flare tip below one section cylindrical shell), hang to the residing position of former flare tip by suspension hook.Behind the location, be fixed on the chimney.As required, suspension bracket (6) can turn round under the effect of external force (manpower) easily, and fixedly the manual chain hoist on the suspension bracket can cooperate the suspension hook on the suspension bracket (6), realizes the installation in position of flare tip.
