Abstract
The utility model discloses a special hanger for a tower loop, and is applied to the technical field of hangers. The special hanger comprises a hanger plate, wherein a sling hole is formed in the upper end of the special hanger; two ear plates are vertically arranged in parallel on the hanger plate; the distance between the two ear plates is equal to or larger than the thickness of a flange of the tower loop; at least two connecting through holes are formed in the two ear plates correspondingly; the distance between the connecting holes is equal to the distance between the various through holes in the flange; bolt connecting pieces are adopted to penetrate the connecting through holes and the through holes in the flange to enable the special hanger for the tower loop to be fixedly connected with the tower loop; the stress area is increased by connecting the bolt connecting pieces and the tower loop flange; the pressure of the force bearing point is reduced, and the safety factor of operation is increased; the bolt connecting pieces with matching strength and the hanger plate and the ear plates with proper thicknesses and materials are adopted, so that the capacity of single hanging weight can reach 20 tons after calculation, hoisting multiple tower loop assembly through a single hanger is realized, the work efficiency is greatly increased, the work quality is improved, and the safety factor is increased.
Description
Technical field
the utility model relates to suspender technical field, particularly a kind of tower circle special hanger.
Background technology
tower equipment is to be bolted part by more piece tower circle to connect to form successively, in prior art for the two kinds of modes that are assembled with of tower equipment: one is to tie up lifting, adopt steel rope that every joint tower circle is tied up to lifting, because equipment is made up of more piece tower circle, every joint tower circle lifting all needs to repeat to tie up and dismantle, complex operation, labour intensity is large, meanwhile, is difficult to guarantee the level of tower circle in the time of assembling in place, need repeated multiple times searching lifting equilibrium point, increased difficulty to the assembling of tower circle; Another is to adopt latch to be directly connected and to lift with hoist cable through the bolt hole on tower circle, in hoisting process, can not guarantee that tower circle does not collide other object, and make device inclined, in addition, hoist cable comes off and easily has an accident from latch, and the edge that tower joint is ironcasting bolt hole is very thin easily to burst apart, and safety misadventure easily occurs, and safety cannot be guaranteed.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of safe, hoisting capacity large, realize singly sling heavy multitower circle assembly set and the high tower circle special hanger of efficiency.
For solving the problems of the technologies described above adopted technical scheme: a kind of tower circle special hanger, comprise boatswain chair, have hoist cable hole in described boatswain chair upper end, on described boatswain chair, be vertically provided with two parallel otic placodes arranged side by side, distance described in two between otic placode is equal to or greater than the flange thickness of tower circle, on otic placode described in two, correspondence has at least two connecting through holes, distance between each through hole on distance and flange between each described connecting through hole equates, with bolts is fixed together tower circle special hanger and Ta Quan through the through hole on connecting through hole and flange successively.
Be further used as the improvement of technical solutions of the utility model, the outside end face that described in two, otic placode is relative with tower circle is inner concave arc surface, and the radian of described inner concave arc surface equates with the cylindrical radian of tower circle.
Be further used as the improvement of technical solutions of the utility model, described boatswain chair is the Q345B steel plate that 30mm is thick, and described otic placode is the Q345B steel plate that 30mm is thick.
Beneficial effect: this tower circle special hanger is connected with the flange of tower circle by multiple bolt connection pieces, by increasing area of thrust surface, reach the pressure that reduces acting point, thereby promote the safety factor of operation, the bolt connection piece that selection intensity matches simultaneously and boatswain chair and the otic placode of certain thickness and material, can reach 20 tons through adjusting the heavy amount that can make singly to sling, thereby realize the heavy multitower circle assembly set of singly slinging, greatly increase work efficiency, improve workmanship, improve safety factor.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the utility model embodiment front view;
Fig. 2 is the utility model embodiment lateral plan;
Fig. 3 is the birds-eye view of the utility model embodiment;
Fig. 4 is the lifting schematic diagram of the utility model embodiment.
The specific embodiment
Referring to figs. 1 through Fig. 4, a kind of tower circle of the utility model special hanger, comprise boatswain chair 1, have hoist cable hole 2 in boatswain chair 1 upper end, on boatswain chair 1, be vertically provided with two parallel otic placodes 3 arranged side by side, distance between two otic placodes 3 is equal to or greater than flange 5 thickness of tower circle 4, on two otic placodes 3, correspondence has at least two connecting through holes 6, distance between each through hole 8 on distance and flange 5 between each connecting through hole 6 equates, with bolts 7 is fixed together tower circle special hanger and tower circle 4 through the through hole 8 on connecting through hole 6 and flange 5 successively.
This tower circle special hanger forms by boatswain chair 1 and two otic placodes 3 suspension hook that a cross section is inverted-F, multiple this suspension hooks are fixed together with tower circle 4 along being circumferentially distributed on the flange 5 of tower circle 4, be connected with the flange 5 of tower circle 4 by multiple bolt connection pieces 7, by increasing area of thrust surface, reach the pressure that reduces acting point, thereby promote the safety factor of operation, adopt suspension ring latch to be connected with steel rope through the hoist cable hole 2 on boatswain chair 1, thereby can facilitate pulsation-free by tower circle 4 installation of slinging by steel rope, and be not easy damage equipment in handling process, the intensity of bolt connection piece 7 and suspension ring latch must be mated, require bolt connection piece 7 to select 10.9 grade high-strength bolts through adjusting, through hole 8 on the flange 5 of specification and tower circle 4 mates, suspension ring latch is selected M30,10.9 grade high-strength bolts.
In the present embodiment, have two connecting through holes 6 at two otic placodes 3, the pore size that this connection is passed through is corresponding with the pore size of the through hole 8 on flange 5, mode with bolts between tower circle special hanger and tower circle 4, and easy disassembly is fixed.
As preferred implementation of the present utility model, the outside end face that two otic placodes 3 are relative with tower circle 4 is inner concave arc surface 9, and the radian of inner concave arc surface 9 equates with the cylindrical radian of tower circle 4.
For the flange 5 of tower circle special hanger better and on tower circle 4 is connected to a fixed, be inner concave arc surface 9 in two otic placode 3 outside end face machine-shapings.
As preferred implementation of the present utility model, boatswain chair 1 and otic placode 3 are made by the thick steel plate of 30mm, and the material of steel plate is Q345B.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken possessing at described technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make various variations.
