Abstract
The utility model relates to a lifting device for large-diameter reinforced concrete pipelines. The lifting device mainly comprises two pieces of H-shaped steel and one connecting rod, and the lifting device is characterized in that the two pieces of H-shaped steel are respectively welded on the same side of the connecting rod and are not mutually parallel, a main lifting point is arranged on one piece of H-shaped steel, and an auxiliary lifting point is arranged on the upper end of the connecting rod. The two pieces of H-shaped steel welded on the connecting rod are respectively used as an upper beam and a lower beam, the lower beam is vertically welded on the connecting rod, the upper beam is obliquely welded on the connecting rod, and the main lifting point is arranged on the upper beam. According to the lifting device provided by the utility model, the main lifting point and the auxiliary lifting point are switched to adjust the angle of the lifting device to enable the lifting device to be inserted in or pulled out from a reinforced concrete pipeline so as to lift the reinforced concrete pipeline. The lifting device provided by the utility model is easy to operate, the lifting device adopts an open design, and the main lifting point and the auxiliary lifting point are switched to enable the lifting device operated by a crane to be inserted in or pulled out the reinforced concrete pipeline, and the reinforced concrete pipeline is not disturbed in the process.
Description
Technical field
The utility model belongs to municipal works field, is specifically related to Large-diameter Steel type reinforced concrete pipeline hanging apparatus in road drainage engineering.
Background technology
In town road drainage works, reinforced concrete pipiline is installed general reeve, the snap ring of adopting and is connected lifting, or adopting the lifting of regenerated fiber suspender belt, the shortcoming of this construction method mainly contains: one, steel rope directly contacts with tube wall, easily causes cement concrete to come off; Two, easily there is slippage in hoisting process pipeline, dangerous; Three, rear pipeline in place is adjusted difficulty; Four, for Large Diameter Pipeline tongue and groove pipe steel rope, be difficult for being wound around and detaching; Five, installation effectiveness is low.The number of tubes of general town road Water Drainage Design of Xi ' is larger, and traditional construction method is difficult to meet the requirement of construction speed and installation quality.
Summary of the invention
The purpose of this utility model is in order to overcome existing reinforced concrete pipiline hanging method hook decoupling device inconvenience, and after handling is in place, plucking steel rope easily makes pipeline that the shortcoming of displacement occurs, and provide a kind of Large-diameter Steel type reinforced concrete pipeline hanging apparatus, in construction, can improve large-diameter pipeline installation effectiveness.
The utility model solves the technical scheme that its technical matters adopts:
Large-diameter Steel type reinforced concrete pipeline hanging apparatus, mainly by two H shaped steel and a pipe link, formed, it is characterized in that: two H shaped steel are welded on respectively on pipe link homonymy, and are not parallel to each other, a H shaped steel is provided with main hoisting point, in pipe link upper end, is provided with secondary suspension centre.
Two H shaped steel that weld on described pipe link are called upper beam and underbeam, and on underbeam vertical welding pipe link, upper beam inclined weld is in succession on extension bar, and upper beam is provided with main hoisting point.
The utility model also comprises rubber cushion, on pipe link and underbeam, is separately installed with rubber cushion, in case damage concrete duct while contacting with concrete duct face.The utility model utilizes the switching of main hoisting point and secondary suspension centre, regulates hanging apparatus angle, inserts and detach concrete duct, carries out concrete duct lifting.
The utility model is simple to operate, and hanging apparatus adopts opened type design, by the switching of major-minor suspension centre.Make loop wheel machine operation hanging apparatus insert and detach concrete duct, not disturbance concrete duct in process.
Accompanying drawing explanation
Fig. 1 is pipeline lifting schematic diagram of the present utility model.
Fig. 2 is disengaging pipeline schematic diagram of the present utility model.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1 and Figure 2, the utility model is mainly comprised of two H shaped steel (3,4) and a pipe link 5, it is characterized in that: two H shaped steel (3,4) be welded on respectively on pipe link 5 homonymies, and be not parallel to each other, on pipe link 5, two H shaped steel (3,4) of welding are called upper beam 3 and underbeam 4, on underbeam 4 vertical welding pipe links 5, upper beam 3 inclined welds are in succession on extension bar 5, and upper beam 3 is provided with main hoisting point 1, in pipe link 5 upper ends, is provided with secondary suspension centre 2.
In order to prevent that this hanging apparatus from damaging concrete duct while contacting with concrete duct face, be separately installed with rubber cushion on pipe link 5 and underbeam 4.The utility model utilizes the switching of main hoisting point 1 and secondary suspension centre 2, regulates hanging apparatus angle, inserts and detach concrete duct, carries out concrete duct lifting.
During the utility model lifting, adopt two isometric steel ropes, hang main hoisting point 1 and secondary suspension centre 2, upper beam 3 levels lean against concrete duct outer surface of upper, and underbeam 4 oblique cuttings enter concrete duct 6, adjust position, as shown in Figure 2; Extract secondary suspension centre 2, slowly lift by crane main hoisting point 1, underbeam 4 level contact concrete duct 6 inwall tops, as shown in Figure 1; Handling concrete duct is in place, and slowly off the hook, makes upper beam 3 levels fall within concrete duct outer surface of upper, as shown in Figure 2; Hang secondary suspension centre 2, hang concrete duct in place, carry out the lifting of next joint concrete duct.
This applicable novel have reasonable in design, make simple, without dropping into too much expense, can easily carry out the constructions such as the hanging of large-diameter concrete pipeline, peace, easy to operate, Simple durable, can avoid concrete duct slippage in construction, save and shortened wire rope handling and unloaded the pipe time, guarantee construction safety, accelerated concrete duct installation effectiveness and precision, greatly promoted concrete pipe pipeline installation construction work efficiency.
