Abstract
The utility model provides an installing lifting device for a steel structure purline, wherein three steel plates are used to weld an active module, an opening at one end of the active module can slide freely along the outer side of a flange plate of a cross beam, size of the opening of the active module is 15-28 millimeters, and a bolt hole is arranged on a cover plate of the active module. The structure has the advantages of solving the problems that lifting cost for a crane is high and is not flexible, or solving the technical problems that the installing lifting device for the steel structure purline can not be used due to site limit, the installing intensity of manual rope lifting and danger with a labor rope is high, and use scope is narrow.
Description
Technical field
The utility model discloses a kind of construction work servicing unit, what be specifically related to is that a kind of steel work purlin is installed lifting appliance.
Background technology
In the building installation engineering, purlin is installed the operational sequence that is absolutely necessary.Purlin installation site absolute altitude in work progress, purlin length, single purlin weight is different different because designing, and changes larger.Generally more than 6M, more than the purlin length 6M, weight is different because of the model of designing requirement for absolute altitude.Examination is generally used the purlin specification take steel structural roof purlin commonly used as example: C160*60*20*2.5=5.715 ㎏/M, if purlin length is 6M, and single purlin weight 34.29 ㎏, if use merely manpower to promote at crossbeam, difficulty is well imagined.Best solution has two kinds at present:
The first is purlin manpower rope lift method: when purlin installation site absolute altitude, purlin length, purlin weight hour can adopt artificial rope lift method to promote purlin.Two people of the method needs fasten seat belts respectively to straddle on the corresponding crossbeam in two ends that needs the mounting purlines position and wait for, on the ground people in the above the premter side-lower with rope firm in the 300MM-400MM place colligation of purlin two ends, then two people that straddle on the beam promote up purlin, and two people use bolt that this purlin (there is bolt hole at two ends) is fixed on the purlin supporting plate of twice crossbeam simultaneously.
Second method is purlin crane rope lift method: the general arm of Standing position of a crane and Liangping row, hoistman need be taken appointment with certificate, below a people (also can two people) colligation purlin (adopting at 2 hangs), two people lift to position to be installed to the purlin that elevates along the girder steel level and with bolt purlin are fixedly mounted on the crossbeam purlin supporting plate simultaneously on the beam.
The shortcoming of purlin manpower rope lift method: when the purlin installation site higher, the purlin length of absolute altitude, when purlin weight is larger, be subjected to people's the capabilities limits the party rule that draws high to be difficult to realize, and promote, install degree of danger and also can correspondingly strengthen.The required purlin quantity of steel work project roofing is generally all many, and adding manpower, to draw high labour intensity larger, and the people is easy to cause physical fatigue under the high-strength working of high-altitude, thereby brings very large negative effect for working security and progress.
Purlin crane rope lift method shortcoming: the higher and crane of the method expense is inadequate maneuverability also, and crane is difficult to put to good use when the place is limited sometimes.Be used for to solve use crane to promote the higher and inadequate maneuverability of expense, or can't use because the place is limited the time and the manpower rope draw high labour intensity is installed, dangerous erecting device large and that use face is narrower is occurring on the market yet.
The utility model content
The utility model provides a kind of making simple according to above-mentioned deficiency, and novel structure is skillfully constructed, maneuverability, and applicability is strong, and efficient is high, and safety is good, and is reusable, and the steel work purlin that the installation cost expense is low is installed lifting appliance.
For achieving the above object, the technical solution of the utility model is that a kind of steel work purlin is installed lifting appliance, described is the active module that can be free to slide along the crossbeam frange plate outside with one end opening of three block plates welding, the opening size of active module is 15-28mm, and the active module upper cover plate is opened a bolt hole.
Described active module upper cover plate bolt hole screws in a bolt.
One of welding is 50-70 ° the bar of encorbelmenting with the active module angle on the described active module.
Suspension ring are fixed in the described bar top of encorbelmenting.
Described suspension ring below hangs a pulley.
Be mounted with rope on the described pulley.
Fix a hook on the described rope.
Described hook diameter is less than the bolt hole size above the purlin.
After technique scheme, the beneficial effects of the utility model are to have solved the use crane to promote the higher and inadequate maneuverability of expense, or can't use because the place is limited the time and the manpower rope draw high labour intensity, dangerous large and use face is narrower technical barrier be installed.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
By shown in Figure 1, a kind of steel work purlin of the utility model is installed lifting appliance, described is the active module 4 that can be free to slide along the crossbeam frange plate outside with one end opening of three block plates welding, and the opening size of active module 4 is 15MM-28MM, and active module 4 upper cover plates are opened a bolt hole.Described active module 4 upper cover plate bolts hole screw in a bolt 3.One of welding is 50-70 ° the bar 6 of encorbelmenting with the active module angle on the described active module 4.Suspension ring 1 are fixed in described bar 6 tops of encorbelmenting.Active module 4 connects by motion bar 5 with the bar of being connected.Described suspension ring 1 below hangs a pulley.Be mounted with rope 2 on the described pulley.Fix a hook on the described rope 2.Described hook diameter is less than the bolt hole size above the purlin.
