Above-mentioned thin devices stone tongs, pass through hole by binding bolt between adjacent two pieces of curved splints and be fixedly connected with nut, and curved splint is connected successively, enclose the host cavity formed with thin devices mating shapes, by thin devices is housed in host cavity, lifted by hanger again, meet the installation lifting of the thinner equipment of wall thickness.
In addition, above-mentioned thin devices stone tongs, according to the size of thin devices by regulating the radian of curved splint, the block number of curved splint, can meet the lifting under various operating environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the thin devices stone tongs of an embodiment.
Fig. 2 is the birds-eye view of thin devices stone tongs in Fig. 1.
Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.First-selected embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, the object of these embodiments is provided to be make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that, when element is called as " setting " at another element, it can be directly can there is element placed in the middle on another element or also.When an element is considered to " be connected " with another element, it can be directly connected to another element, or may there is centering elements simultaneously.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in specification sheets of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.
Refer to Fig. 1 ~ 2, a kind of thin devices stone tongs, comprise fixing device and be arranged on a pair hanger 20 symmetrical on fixing device.
Wherein, fixing device comprises at least two pieces of curved splints 10.
Wherein, the two ends of every block curved splint 10 are provided with connecting panel 12.
Each connecting panel 12 is provided with multiple through hole.
Pass through hole by binding bolt between adjacent two pieces of curved splints 10 and be fixedly connected with nut.
Preferably, each connecting panel is also provided with multiple reinforced rib, for strengthening the bearing capacity of this thin devices stone tongs.
Curved splint 10 is connected successively, encloses the host cavity 14 formed with thin devices mating shapes.
Host cavity 14 is namely for accommodating thin devices.
Be appreciated that, be not limited by binding bolt between adjacent two pieces of curved splints 10 pass through hole and be fixedly connected with nut, in other embodiments, between adjacent two pieces of curved splints 10, other connection modes can also be adopted, as long as adjacent two pieces of curved splints 10 can be fastenedly connected.
In the present embodiment, above-mentioned thin devices stone tongs comprises two pieces of curved splints 12.This curved splint 12 is semicircle.
Consider the material particularity of some equipment, curved splint 12 is also provided with neonychium 16, for insulation blocking near the side of thin devices.
Preferably, neonychium 16 is rubber pad.
Use above-mentioned thin devices stone tongs to need to carry out supports reinforcement in thin devices cylindrical shell, hanging method improved simultaneously, the suspension centre of slipping tail crane will on move, change with leading the height change of hanging lifting.
The mechanics principle of above-mentioned thin devices stone tongs:
At thin devices suspension centre position, thin devices stone tongs be installed and make it to clamp with thin devices to produce maximum static friction force, meeting the total force of thin devices and platform, ladder, attached tower pipeline etc. during lifting.
Mechanical analysis: the maximum static friction force between thin devices stone tongs and thin devices equals the product of positive pressure and friction coefficient, that is: F=f × N
In formula, F is the maximum static friction force between thin devices stone tongs and thin devices;
N is the positive pressure between thin devices stone tongs and thin devices;
F is the coefficient of static friction between thin devices stone tongs and thin devices.
Binding bolt adds up to n, if each binding bolt predetermincd tension is
, then the total positive pressure between thin devices stone tongs and thin devices be N=n ×
.
Wherein, the standard of each binding bolt allows pulling force to be [F]=As × [σ]
In formula, As is the cross-sectional area of binding bolt,
;
[σ] is binding bolt material permissible stress.
In the present embodiment, it is the high strength bolt of 35CrMoA that binding bolt is preferably 8.8 grades of M56 × 280 materials,
，
The permission pulling force limit of single binding bolt is
Take off charcoal four tower for T-201, barrel diameter is Φ 2200/1800/1200mm, and material is the coefficient of static friction of TA2, fixture and equipment room
, equipment is heavily 22.481 tons, and tower inner support circle, slinger's fixture etc. are heavily 4.0 tons, and fixture uses 10 bolts, and each bolt need provide predetermincd tension
Standard permission pulling force because of binding bolt is 20.8 times of predetermincd tension, therefore the binding bolt selected can provide enough predetermincd tensions, can guarantee that hoisting process is safe and reliable.
Above-mentioned thin devices stone tongs, be applied in the SBA Apparatus and system matching construction of 60,000 tons/year, hoisting cost decreases more than 130 ten thousand yuan than creeling body lifting cost, and installation period shortens half wheat harvesting period, and cost of labor decreases more than 80 ten thousand yuan.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
