Abstract
The invention relates to an overhead and butt-joint method for a box-type headframe, which is characterized in that the method comprises the following steps of: a. manufacturing the box-type headframe as two parts: a mainbody headframe (1) and a hoisting headframe (5); b. installing a well head vertical frame (8) and the mainbody headframe (1) at the proper place according to a normal installation method; c. adopting a hoisting equipment to hoist the hoisting headframe (5) so as to carry out butt-joint positioning with the mainbody headframe along a positioning block; and d. welding the joint of the hoisting headframe and the mainbody headframe, thus forming the box-type headframe entirety. The method has the advantages of: 1. manufacturing and installing the box-type haedframe by section, breaking through the traditional hoisting process, thus reducing the space occupying of the construction field; 2. carrying out installation without stopping production, thus avoiding the loss due to production stopping; and 3. being capable of being applied to the technical renovation engineering of old coal mine and reducing the removal expense of the original building and the loss owning to production stopping.
Description
Technical field
The technical field that the box-type headframe that the present invention relates to use in colliery, the metal mine lifts under the particularly very narrow on construction ground situation, is engaged in the hoisting of large-scale box type derrick.
Background technology
At present, domestic all is to adopt disposable integral body directly to be lifted by crane traditional hoisting with derrick, but under the very narrow occasion in some well head places, because the box-type headframe entire length has surpassed the well head place, cause and can't on-the-spot integral body make box-type headframe, let alone the integral hoisting box-type headframe.As Turkey's Ku Zilu colliery auxiliary shaft Hoisting System is the technological transformation project in this colliery, the very narrow and moulding in job site, execution conditions are subjected to serious restriction, derrick lifting has been the difficult problem of whole Hoisting System project installation since this project is submitted a tender always, and the well head construction plant is narrow especially, resemble that this execution conditions can not see at home, moreover, the owner require construction period its mine car and the road of automobile fortune coal must guarantee unimpededly in construction period, can not cause full ore deposit to stop production.Extensively retrieve at the problems referred to above, do not find relevant solution as yet.
Summary of the invention
Purpose of the present invention is exactly to surpass under the occasion in well head place the problem how box-type headframe is installed, a kind of segmental hoisting structure and the hanging method thereof of proposition in order to solve in box-type headframe length.
To achieve these goals, the present invention has adopted following technical scheme:
A kind of box-type headframe lifts docking calculation in the air, it is characterized in that may further comprise the steps:
A, box-type headframe is made main body derrick and lifting derrick two parts, main body derrick upper end is provided with articulated mounting and is articulated and connected with the lifting derrick, and the upper end of body derrick is provided with and lifts the locating piece that derrick cooperates, and can be provided with guiding surface on the locating piece
B, well head stand and main body derrick are in place according to conventional mounting method;
C, adopt hanging device will lift derrick to sling and dock location with the main body derrick along locating piece aloft, and make the articulated mounting on the main body derrick and lift derrick and be articulated and connected;
D, will lift derrick and main body derrick junction is welded, constitute box-type headframe integral body.
The invention has the advantages that:
1, by the segmentation of box-shaped derrick is made, installed, the hoisting that breaks traditions dwindles the occupation of land space of construction plant with this, and other building project can carry out in advance, shortens well construction period;
2, can under the ground situation that do not stop production, install, can avoid the loss that stops production;
3, can be applied in the technology innovation project of old ore deposit, reduce the demolition cost and because the loss that stops production and bring of existing building.
The present invention is further described below in conjunction with drawings and Examples.
Description of drawings:
Fig. 1 is the vertical view of main body derrick;
Fig. 2 is the vertical view of lifting derrick;
Fig. 3 is well head stand and main body derrick installation network for location;
Fig. 4 is lifting derrick and main body derrick installation network for location;
Fig. 5 is the I portion zoomed-in view of Fig. 3;
Fig. 6 is that the A of Fig. 3 is to view;
Fig. 7 is the II portion zoomed-in view of Fig. 4;
Fig. 8 is the B-B sectional view of Fig. 7.
The specific embodiment:
As shown in Figure 1 and Figure 2, because the narrow requirement that can not satisfy the derrick overall package in place is divided into two sections manufacturings with the box-shaped derrick.Shown in Figure 1 is main body derrick 1, is positioned at well head 4 centers during manufacturing, and main body derrick 1 end one side is provided with hinged seat 2, and both sides are provided with locating piece 3 in addition.Shown in Figure 2 is lifting derrick 5, and its lower surface is provided with hinged ear 6 and is connected cooperation with hinged seat 2.
As shown in Figure 3, earlier with main lead 7 pull-ups of main body derrick 1 usefulness, fixing after arrival certain altitude and the gradient; Lift by crane well head stand 8 then and be installed in well head 4, main body derrick 1 is connected with well head stand 8.The installation of well head stand and main body derrick belongs to conventional mounting method.
As shown in Figure 4, adopting hanging device will lift derrick 5 slings, locating piece butt joint location on from the top along the main body derrick, and make hinged seat 2 aligned fit on the hinged ear 6 of lifting on the derrick and the main body derrick, adopt taper bearing pin 2a that hinged ear 6 is connected in hinged seat 2, the taper gradient of taper bearing pin is 1: 10, and axle is 1.5mm with the gap in hole.Concrete structure such as Fig. 7, shown in Figure 8, wherein hinged ear 6 is certain angle with hinged seat 2 and main body derrick center line.
At last, will lift derrick and main body derrick junction is welded, constitute box-type headframe integral body.In the welding process, also take following technical measures:
(1) in order to ensure hinge current stabilization in welding, carry out in strict accordance with the requirement of " code for acceptance of construction quality of steel structures " for this processing work, adopt half oxygen cutter to carry out blanking, the preceding iron rust with steel cutting zone surface of gas cutting, dirt etc. are cleaned out, slag, burr and the splash etc. at cleaning groove and edge behind the gas cutting, the work piece cut face must not have crackle, is mingled with, layering and greater than the truncation of 1mm.
(2) in order to guarantee weldquality, adopt DC welder, solder flux adopts the E4315 welding rod to weld, and welding rod should be dried at drying baker, and welding rod is put into incubator after curing, and the stability of welding arc is guaranteed in ready access upon use.
(3) in order to reduce the seam deformation of member, take symmetric method to weld for the hinge both sides, and the welding rod of symmetrical both sides, welding current are consistent, the welding rod of backing welding should adopt the welding rod of φ 3.2mm, continuous welding is adopted in the multilayer welding, the every layer of intact back of welding bead cleaning in time, welding again after the removal of defects.
Separately assemble during (4) owing to epimere and hypomere, can not accurately dock owing to assembly error in the time of might causing butt joint like this.Should fully take into account the amount of contraction of welding during its derrick epimere assembling, can determine grade size of opening of its assembling, answer appropriateness to emit the welding allowance for shrinkage according to the amount of contraction of derrick principal piece welding.After finishing, welding reexamines the location dimension of hinge up and down.
(5),, must adopt and same steel ruler be measured, to guarantee unanimity as a result, the deviation that the minimizing measurement causes for the hinge location of upper and lower section connection of derrick because separately assembling when epimere and hypomere.
