The utility model discloses make full use of stove bottom space and heating furnace stand with the help of capstan winch and pulley gear, with steel cable pulling combustor lug, light lifting or put down large-scale combustor, accomplish combustor dismantlement installation work safely.
Description
Technical Field
The utility model belongs to the technical field of jacking equipment, concretely relates to large-scale combustor's of stove bottom installation lifting devices of tubular heating furnace random subsidiary.
Background
The tubular heating furnace is special equipment in the petrochemical industry, and periodically needs to enter a hearth to manually inspect and maintain a furnace tube and an internal heat insulation layer; the burner is important equipment of a tubular heating furnace, needs regular maintenance, is generally arranged at the bottom of the furnace, and has the weight of 400 plus 10000 kg. The space of the furnace bottom is generally 2-2.3m, the furnace can not be disassembled and assembled by a crane or a forklift, and the furnace is moved to the center of the furnace by a crowbar and is fixed by bolts when a plurality of people lift the furnace to the assembly height. The large burner can not be lifted, and the central burner body is disassembled and installed twice. The removal is the reverse process. Manual installation is time consuming, labor intensive and dangerous.
A special and specially-made movable forklift with a shorter lifting upright post can be purchased, the total height is 1.8m, the special movable forklift can enter the furnace bottom, a large-sized burner is conveyed to the furnace bottom, the burner is lifted to the installation position, and then the installation is completed by manpower. However, a specially-made forklift needs to be customized, so that the cost is higher; after the forklift is used, the forklift is not closely related to the furnace body, so that the maintenance interval is long and the forklift is easy to lose.
SUMMERY OF THE UTILITY MODEL
In view of the above technical problem, the present invention provides a random furnace bottom large burner installation and lifting device for a tubular heating furnace, which can easily lift or lower a burner, especially a large burner with a weight of more than 500kg, in a limited space at the furnace bottom of the tubular heating furnace, thereby completing installation or maintenance and detachment operations.
The specific technical scheme is as follows:
the device comprises a lifting device for mounting a large-scale burner at the bottom of the furnace, which is attached to a tube-type heating furnace randomly, wherein manual winches are respectively mounted at the bottoms of two opposite vertical columns of each heating furnace, pulleys are respectively mounted at the tops of the two vertical columns, and steel ropes of the manual winches are hung on lifting lugs of a burner shell after being turned by the pulleys.
The manual winch is provided with a locking device.
The random attached burner mounting and lifting device fully utilizes the space of the furnace bottom and the upright post of the heating furnace, and pulls the lifting lug of the burner by a steel rope by means of a winch and a pulley device, so that the large burner is easily lifted or put down, and the dismounting and mounting work of the burner is safely finished.
The utility model discloses a technical effect who has:
1. at least 5-6 skilled strong personnel are needed for disassembling and assembling the original burner, the disassembly or assembly can be completed in 4 hours, only 2 people are needed at present, and the disassembly (assembly) can be completed in about 1 hour;
2. originally pure manual work can be installed below 500kg at most, and can not be completed again, 2 1000kg manual winches are adopted at present, 10001kg heat accumulating type burners are easily and safely disassembled;
3. the anti-human body-lifting device is stable and stable in lifting compared with a shoulder, the connecting bolt is convenient to install, and the requirement of safe production is met.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical scheme of the utility model is explained by combining the attached drawings.
As shown in figure 1, the tube-type heating furnace is randomly attached with a device for installing and lifting a large-scale burner at the bottom of the furnace, manual winches 3 are respectively installed at the bottoms of two opposite vertical columns of each heating furnace, pulleys 1 are respectively installed at the tops of the two vertical columns, and steel ropes 2 of the manual winches 3 are hung on lifting lugs of a burner shell after being turned by the pulleys 1; the manual winch 3 is provided with a locking device.
Aiming at the characteristics that the bottom of the tubular heating furnace is limited in height and the periphery of the tubular heating furnace is provided with upright columns, manual winches 3 are arranged on two upright columns opposite to each heating furnace, and are turned by pulleys 1, and steel ropes 2 are hung on lifting lugs of a combustor shell to lift the combustor. Only 2 people hand-operated manual winches 3 are needed to operate easily, and the operation space of the center of the furnace bottom is not occupied.
When the burner is 1000kg, each manual winch 3 bears 500kg, and the manual winch 3 has bidirectional self-locking and can not slide. The gear pair gear ratio of the manual winch 3 is 8: 1; the diameter of the pinion is about 80mm, the length of the hand crank is 350mm, the hand crank is driven by the mechanical principle to swing at the position of the hand crank with the power of 500X (1/8)/(350/80) to 14.3 kilograms of force to 143N, and common people can easily swing the hand crank.
During installation, the steel rope 2 is hung on the combustor lifting lug by utilizing the characteristic that the rope is pulled up to allow a small amount of skew deviation, the combustor arranged beside the furnace body can be dragged to the furnace bottom by shaking the manual winch 3, then the steel rope 2 is tightened to be lifted to the installation height, and the installation is completed by connecting bolts. The hand winch 3 and the wire rope 2 remain in this position after installation.
When overhauing and dismantling the combustor, take tight steel cable 2, dismantle the bolt, reverse wave manual capstan winch 3 and make the combustor fall to being close to ground, the manual work is given certain horizontal thrust, makes combustor skew center installing port place ground, realizes that personnel can get into the heating furnace through the installing port and overhauls the mesh ground. After the maintenance is finished, the manual winch 3 is shaken to lift the burner to the mounting position, and the connecting bolt finishes the mounting work.
The manual winch 3 and the pulley 1 are both assembled on the heating furnace upright post and the furnace bottom section steel, and the furnace bottom maintenance space is not occupied. The lifting device belongs to an integrated accessory of a heating furnace, has low cost and is not easy to lose.
