Description
Technical field
The present invention relates to cable Setting-out Technique, specifically refer in construction the servicing unit of payout from the top down.The present invention also relates to this servicing unit method of payout from the top down of utilizing simultaneously.
Background technology
In on the middle and senior level, construction of super highrise building, the trend of cable and to lay be an important engineering.Conventionally cable, first along downward cabling on body of wall, vertical shaft, then according to design, is applied to respective storey, then lays at every floor.For above-below direction cabling, often take the mode of unwrapping wire from top to bottom to carry out, on every floor plate that cable passed through, be provided with a cable-through hole, after cable laying puts in place, then fireproof blocking is done in hole.On wall, be provided with ladder, the cable of above-below direction is just fixed on ladder.What at present unwrapping wire relied on from top to bottom is the gravity of cable self and realize falling voluntarily, but there is a very large problem in the mode of this dependence gravity fall: the weight falling along with cable constantly increases, if do not intervened, cable falling speed can be more and more faster, therefore more to below, control more difficult (because the weight of cable and speed are all increasing) to cable, this needs more workmen jointly to hold cable to overcome cable gravity undoubtedly, cable can slowly be fallen, once speed is out of control, just may there is the cable serious security incident of this class of hurting sb.'s feelings.
Summary of the invention
For prior art above shortcomings, the object of the present invention is to provide the laborsaving and unwrapping wire process of a kind of unwrapping wire to hold in manageable construction the servicing unit of payout from the top down.
According to this device, the present invention has proposed a kind of new line-putting method simultaneously.
To achieve these goals, the technical solution used in the present invention is such: the servicing unit of payout from the top down in construction, this device comprises at least three fixed pulleys, fixed pulley is fixedly mounted on vertical pole above and respectively in different height, all fixed pulleys are positioned on same vertical plane; Has can be the relatively vertical pole left and right adjusting of a fixed pulley at least to change the horizontal range between this fixed pulley and adjacent fixed pulley; On vertical pole, be provided with for the fixing horizontal cross bar of floor, between the horizontal cross bar other end and the vertical pole on horizontal cross bar, be provided with brace.
Further, described horizontal cross bar is two (corresponding brace is also two), and two horizontal cross bars are positioned at same plane and mutually vertical.
Described fixed pulley is three, lays respectively at vertical pole upper end, lower end and middle-end, and horizontal cross bar is between lower end and middle-end two fixed pulleys.
Vertical pole, horizontal cross bar and brace in this servicing unit are angle steel and make.
Utilize this servicing unit from the top down the new method of unwrapping wire be:
(1) erection auxiliary device: the horizontal cross bar on above-mentioned servicing unit is fixed on floor by connector, thereby by servicing unit integral installation on floor, and make the vertical pole on servicing unit be arranged in the cable-through hole on floor;
(2) coiling and unwrapping wire: cable one end that needs are transferred intersects and walks around all fixed pulleys successively from top to bottom, can utilize cable gravity to start unwrapping wire, in unwrapping wire process, regulate as required certain relatively vertically fixed pulley of pole left and right adjusting, to change the horizontal range between this fixed pulley and adjacent fixed pulley, thereby the speed that cable is transferred is controlled.
Compared with prior art, the present invention has following beneficial effect:
1. unwrapping wire is laborsaving.Because the frictional force that cable falls can change by fixed pulley that can left and right adjusting, the horizontal range between this fixed pulley and adjacent fixed pulley is larger, and cable friction power is larger, and cable falling speed is slower, otherwise faster.And along with the carrying out of unwrapping wire process, constantly the size of regulating friction force, to control at any time falling speed, does not therefore need too many people to coordinate, and only needs two people can realize the light control of falling speed.
2. because payingoff speed is controlled, therefore whole unwrapping wire process is fool proof, reduced construction safety hidden danger.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Referring to Fig. 1 and Fig. 2, from scheming, can find out, the servicing unit of payout from the top down in construction of the present invention, comprises at least three fixed pulleys 1, fixed pulley 1 is fixedly mounted on vertical pole 2 and respectively in different height, and all fixed pulleys 1 are positioned on same vertical plane; (regulative mode of realizing this function can have multiple: such as this fixed pulley is connected with vertical pole by a cross bar to change horizontal range between this fixed pulley and adjacent fixed pulley to have can be relatively vertical pole 2 left and right adjusting of a fixed pulley 1 at least, on cross bar, there is a chute, fixed pulley can move left and right along chute, and now cross bar is fixed with vertical pole position; Or this fixed pulley is fixed on cross bar, cross bar can move left and right along vertical pole; Or cross bar can rotate around vertical pole, at cross bar during in level, fixed pulley and vertical pole distance farthest, thereby realize left and right adjusting).On vertical pole 2, be provided with for the fixing horizontal cross bar 4 of floor 3, between horizontal cross bar 4 other ends and the vertical pole 2 on horizontal cross bar, be provided with brace 5, thereby make vertical pole 2, horizontal cross bar 4 and brace 5 form right angle triangles, to strengthen the intensity of servicing unit self.
As an embodiment, described horizontal cross bar 4 is two (corresponding brace is also two), two horizontal cross bars 4 are positioned at same plane and mutually vertical, thereby form two right-angled triangles, two right-angled triangles share this right-angle side of vertical pole, make like this intensity of this device further strengthen.
As an embodiment, as shown in Figure, this device fixed pulley 1 is three, lays respectively at vertical pole 2 upper ends, lower end and middle-end, horizontal cross bar between lower end and middle-end two fixed pulleys, the fixed pulley that can move left and right for middle that.
Vertical pole, horizontal cross bar and brace in this servicing unit are angle steel and make, and angle steel intensity is good, and material source is wide, even can utilize obsolete material, for unit in charge of construction, easy to make.
Line-putting method of the present invention is as follows, sees Fig. 1 and Fig. 2:
(1) erection auxiliary device: horizontal cross bar all on servicing unit of the present invention 4 is fixed on floor 3 by connector (as expansion bolt), thereby on floor 3, and make the vertical pole on servicing unit be arranged in the cable-through hole on floor servicing unit integral installation;
(2) coiling and unwrapping wire: cable 6 one end that needs are transferred intersect and walk around all fixed pulleys 1 successively from top to bottom, in Fig. 1, arrow represents the trend of line, can utilize cable gravity to start unwrapping wire, in unwrapping wire process, regulate as required certain relatively vertically fixed pulley of pole left and right adjusting, to change the horizontal range between this fixed pulley and adjacent fixed pulley, thereby the speed that cable is transferred is controlled.
On body of wall 7, be provided with ladder 8, after the cable 6 of above-below direction puts in place, be just fixed on ladder 8.
The above embodiment of the present invention is to be only explanation example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make on the basis of the above description other multi-form variation and changes.Here cannot give all execution modes exhaustive.Every still row in protection scope of the present invention of apparent variation that technical scheme of the present invention amplifies out or change that belong to.
