Abstract
The utility model discloses an A-framed derrick for hoisting a heavy object. The A-framed derrick comprises a main rod, a supporting rod and a lifting lug, wherein the main rod is obliquely arranged; the top end of the supporting rod is arranged on the middle part of the main rod; the bottom ends of the main rod and the supporting rod are arranged on an equipment basic member through welding respectively; and the lifting lug is arranged at the top end of the main rod. The A-framed derrick has the advantages of simple structure, easiness and convenience in operation, suitability for hoisting operation of centralized hoisting work and a small movement range, capabilities of increasing the efficiency of the hoisting work and reducing the cost of the hoisting work and good economic benefit.
Description
Technical field
The utility model relates to a kind of A-frame for hoisting heavy.
Background technology
In some construction occasion, because the camp site is narrow, large-scale elevator machinery inconvenience enters the workyard and carries out operation; Perhaps the camp site lacks other construction machinery and equipment; Or because the work capacity of lifting is few, adopting the large scale hoisting machinery cost high, alerting ability is relatively poor.Therefore field fabrication is convenient and simple, and installation and removal is easy to suspender can remedy the shortcoming that the large scale hoisting machinery cost is high, manoevreability is not enough.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of A-frame for hoisting heavy, this herringbone gin pole is simple in structure, easy and simple to handle, the hoisting operation that applicable crane lifting service is concentrated, moving range is little, improved lifting operation efficient, reduced the cost of lifting operation, have good economic benefit.
For solving the problems of the technologies described above, the A-frame that the utility model is used for hoisting heavy comprises mobile jib, strut and hanger, described mobile jib is obliquely installed, described mobile jib middle part is located on described strut top, the bottom of described mobile jib and strut is located on the Equipment Foundations member by welding respectively, and described hanger is located at described mobile jib top.
Further, this herringbone gin pole also comprises base, and the bottom of described mobile jib and strut is located on the described base by welding respectively.
Further, connect by full weld respectively between above-mentioned mobile jib, strut, base and the hanger.
Because being used for the A-frame of hoisting heavy, the utility model adopted technique scheme, be that this herringbone gin pole comprises mobile jib, strut and hanger, mobile jib is obliquely installed, the mobile jib middle part is located on the strut top, the bottom of mobile jib and strut is located on the Equipment Foundations member by welding respectively, and hanger is located at described mobile jib top.This herringbone gin pole is simple in structure, and is easy and simple to handle, the hoisting operation that applicable crane lifting service is concentrated, moving range is little, improved lifting operation efficient, reduced the cost of lifting operation, have good economic benefit.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation that the utility model is used for the A-frame of hoisting heavy.
The specific embodiment
As shown in Figure 1, the A-frame that the utility model is used for hoisting heavy comprises mobile jib 1, strut 2 and hanger 3, described mobile jib 1 is obliquely installed, described mobile jib 1 middle part is located on described strut 2 tops, the bottom of described mobile jib 1 and strut 2 is located on the Equipment Foundations member by welding respectively, and described hanger 3 is located at described mobile jib 1 top.
Further, this herringbone gin pole also comprises base 4, and the bottom of described mobile jib 1 and strut 2 is located on the described base 4 by welding respectively.The movement of this herringbone gin pole is convenient in the setting of base, can as required A-frame be arranged at the correct position of weight lifting.
Further, connect by full weld respectively between above-mentioned mobile jib 1, strut 2, base 4 and the hanger 3, guarantee the reliability that each parts of this herringbone gin pole connect, improve whole rigidity.
This herringbone gin pole is simple in structure, easy to operate, each parts can be gathered materials on the spot in the production scene, get the solid drawn pipe of one section diameter 80mm, 3 meters of length, wall thickness 3.5mm as mobile jib, as strut, hanger of mobile jib top solder is cut the mobile jib top open at one section straight length that cuts oblique groove of this section pipe middle point vertical welding, hanger is mounted to the mobile jib top, then adopts full weld to connect; Base can adopt I-beam section and two block plates to be welded to form, and two block plate balanced weldings consist of the Steady base that supports mobile jib and strut on the edge of a wing at I-beam section two ends.When this herringbone gin pole uses jack is hung on the hanger on mobile jib top, utilize jack to get final product lifting heavy; Can adopt a plurality of gin pole combined hangings for the greater weight object.This herringbone gin pole has higher alerting ability, and at narrow space, in the lifting operation that crane can't be realized, A-frame can replace crane, gives jack with the place of taking root; When some place jack is affiliated to nowhere, then take up an area the suspension centre that less A-frame can provide weight, have stronger practicality; The operating costs of large-scale hoisting machinery has been saved in the simultaneously utilization of this herringbone gin pole, has reduced the cost of lifting operation.
This herringbone gin pole is applied to certain Power Plant and sets up in flue gas desulfur device, the former flue Steel Structure Installation of the improvement engineering process, because former flue Steel Structure Installation is the old support of part utilization, and connection steel structure pillar above the former old flue, top Steel Structure Installation can't realize with crane at all, adopt this herringbone gin pole to take root at steel column, the hoisting steel structure is implemented to install, the problem that releasing can't be installed without the suspender steel structure, greatly improved installation rate, duration has shifted to an earlier date 20 days, saved simultaneously very large manpower, financial resources, material resources.Facts have proved that this herringbone gin pole uses simple, maneuverability, be convenient to move, efficient is high.
