The specific embodiment
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
The special hanger of hoisting flue bent pipe of coke oven provided by the invention, its structure be as shown in Figure 1: mainly be made up of fixed support plate 3, rotating clip hook 4 and stretching device.
Described fixed support plate 3 has two, and its structure such as Fig. 1, Fig. 7 and shown in Figure 8: this fixed support plate is made by steel plate, which is provided with a hole for hoist 1 and a pin-and-hole 9; Steel plate thickness is 16mm, and hole for hoist 1 diameter is φ 30mm, and these technical parameters also can be decided according to actual conditions.And weld a block plate 5 in this fixed support plate bottom and form T-shaped with fixed support plate, this steel plate 5 is of a size of 70 * 30mm, and this size also can be decided according to actual conditions.
The structure of described rotating clip hook 4 such as Fig. 1, Fig. 5 and shown in Figure 9: by the folder hook and with it the latch 2 that is weldingly connected of top form.The folder hook be a kind of by thickness be the steel plate of 16mm to be made into radius bend be 45 ° folder hook for the 40mm angle, these technical parameters also can be decided according to actual conditions.Latch 2 is made by round steel, and its length is longer slightly than folder hook upper width, and its diameter is littler than pin-and-hole 9, if the diameter of pin-and-hole 9 is φ 20mm, then the diameter of latch 2 is φ 16mm, can guarantee like this can rotate freely after this latch penetrates pin-and-hole 9.
The annexation of above-mentioned rotating clip hook 4 and fixed support plate 3 such as Fig. 1, Fig. 4, Fig. 5 and shown in Figure 6.
The structure of described stretching device such as Fig. 1, Fig. 2 and shown in Figure 3 are by strut 6, spend blue bolt 7 and draw-in groove 8 to form.Wherein: strut 6 has two, and they are positioned at the both sides of spending blue bolt 7, and their end is provided with the draw-in groove 8 that is weldingly connected with it, and their other end links to each other with spending blue bolt 7 respectively.Draw-in groove 8 is that the steel plate of 16mm is made by thickness, and its notch 8-1 is used to block fixed support plate 3, and this steel plate thickness also can be decided according to actual conditions.Spend blue bolt 7 can adopt M20 to spend blue bolt.The parts of this stretching device combine by actual bend pipe caliber size.
The relation that above-mentioned stretching device links to each other with two fixed support plates 3 as shown in Figure 1.
The special hanger of hoisting flue bent pipe of coke oven provided by the invention (abbreviation suspender), its working process is:
1. install and fix suspender:
Two suspenders are arranged symmetrically in the top of coke oven flue elbow 10 (hereinafter to be referred as bend pipe), earlier rotating clip hook 4 is hooked the flange bottom of bend pipe, rotate fixed support plate 3 again, fixed support plate 3 vertically is close to this elbow internal wall, and require to be symmetricly set on the axis that the round mouth center, upper and lower with bend pipe coincides, and with the stretching device two fixed support plate stretchings are located, prevent from suspender to be come off because of rotation fixed support plate 3 deflects;
Then, be connected by shackle near the fixed orifice on the end that will restrict with a strap on the fixed support plate 3 of described bend pipe center of gravity direction and the fixed support plate 31, the other end of this steel rope is linked up with 11 with an end that lifts by crane the manual lifting gear 12 that draws usefulness (as chain block etc.) and is connected; Link to each other with the suspension hook 13 of lifting appliance (crane) with the end hook of another root strap lifting gear 12 (as chain block etc.); Fixed orifice 1 with an end of a long steel rope 14 and another fixed support plate 3 is connected by shackle, and the other end of this steel rope is connected to suspension hook 13 places of lifting appliance (crane).
Notice that manual lifting gear 12 will be fixed near on the fixed support plate of equipment center of gravity, just so that the bend pipe center of gravity is adjusted to perfect condition, through arranging that so just in time being pooled to any after this moment, two suspension centres were put on steel rope is suspension hook 13 places.
2. lifting:
Lifting appliance (crane) when lifting, progressively adjust manual lifting gear 12 and make fixedly that the steel rope at two ends reaches state of equilibrium.Under two that the act on fixed support plate 3 tops relative effects of tractive force obliquely, this suspender clamps bend pipe automatically and catches on bend pipe flange bottom.
3. control is adjusted:
Flue bent pipe can realize that the center of gravity state of the equipment of adjusting satisfies installation requirements by adjusting manual lifting gear 12 as required in hoisting process.
