Description
Technical field
The utility model relates to the auxiliary device of electrical equipment construction, specifically is a kind of vertical pay off rack.
Background technology
Vertical pay off rack is the auxiliary device that is used for power transmission sequence payingoff construction process, described payingoff construction process is meant: thereby when using machinery strand mill or winch to receive steel rope traction lead, in drum, penetrate paying out reel and be erected at it is freely rotated, lead by constantly from drum the exhibition of hauling out puts.The vertical pay off rack that in said process, uses, its structure generally as shown in Figure 1, it comprises body frame 11 and is installed in oil jack 12 on the body frame that the top of oil jack is provided with an axle sleeve 13.
In the work progress, drum is placed ground, a pay off rack is respectively put on both sides.Because body frame 11 altitude hold need be filled up below pay off rack with the indefinite chock of quantity, institute's mat thickness is decided according to the drum size.Then the steel bobbin is penetrated in the axle sleeve 13 of drum and two pay off racks, the handle of use jack is pressing up and down, to regulate the drum height.
There is following problem in the use of this structure:
1, sets up complicated difficulty.Because the body frame aspect ratio is less, need the pad chock below, chock is not of uniform size, smooth degree varies is especially set up the comparison difficulty on irregular landform, consume plenty of time and manpower, sometimes in order to adapt to big drum, need dig pit, operate very inconvenient on ground.
2, stability is not high.Because the height of body frame is less, on the pad behind the chock, can not make between body frame and the chock and firmly connect, and in the unwrapping wire process, especially in longer strain section unwrapping wire, because lead is on ground and aerial unbalance stress, can produce bigger tension force, especially after running into mao bamboon and getting over coil holder and trees obstacle, therefore lead need produce very big tension force could break through these obstacles, is that drum can produce great impact power to line top, causes that drum rapidly rotates, jolts, severe vibration, then need drum is braked this moment, uses drill rod usually.In practice of construction, because the stability problem of pay off rack, drum rolls out coil holder and strides the phenomenon of collapsing and take place often from coil holder.This not only can threaten the personnel's of drum place personal safety, and the staff also needs again the good drum of frame, has wasted the time, has influenced construction speed.In addition, it is also unfavorable to the service life of facility that coil holder unstable and striding collapsed, and facts have proved, its service life has been shortened in operating vibration and topple and destroyed the oil sealing of oil jack easily, has increased the cost of Work tool.
3, the adjusting difficulty is big.Use jack to regulate difficulty of drum aspect ratio, it is time-consuming require great effort, and cause jack oil sealing destruction cause malfunctioning after, this phenomenon is obviously aggravated.Seriously increase difficulty of construction, influenced construction speed and efficient.
4, the rotating element component wear is serious.Wearing and tearing aggravate axle sleeve with bobbin in long-term use, and it is malfunctioning to cause drum to rotate; When the drum rotation is obstructed, need bigger tractive force, tension force savings back discharges and causes drum to jolt seriously, and the danger of overturning is arranged.
Summary of the invention
The trapezoidal technical matters to be solved of this practicality is, provides that a kind of structural stability of using is good, height adjustment range is big in power transmission sequence payingoff construction process, easy to adjust, vertical pay off rack that running resistance is little.
Vertical pay off rack of the present utility model includes the body frame of a framed structure, is fixed with two vertical columns on body frame side by side; Also be provided with a four-bar linkage in the body frame, this four pipe links mechanism includes four pipe links, be respectively arranged with superposed upper bracket on four hinge-points between four connections, be positioned at the bottom lower bracket, be positioned at anterior nut and be positioned at the jacking block at rear portion; Be respectively arranged with two pilot holes on described upper bracket and the lower bracket, upper and lower support also can move along column is upper and lower by pilot hole and two root post sockets; Be provided with a rhizoid bar between described nut and the jacking block, the rear end of screw mandrel withstands on the jacking block, and the thread segment and the nut of screw mandrel are connected; Be placed with a plurality of knock holees from top to bottom on two root posts, and every root post is provided with a location pin that can partly insert in any knock hole, the exposed portions serve of location pin is blocked in the bottom of above-mentioned lower bracket.
The top of described upper bracket has a groove that is used for settling bobbin, has been arranged side by side a pair of roller in the bottom of groove.
The utility model sound construction, set up with easy to adjust.Because it has adopted the height adjustment mechanism of four-bar linkage structure, the height and position of four-bar linkage itself can be adjusted the location on column simultaneously, thereby improved its height adjustment range greatly, save the in use required chock of traditional vertical pay off rack, guaranteed the stability and the safety of operation.In addition, in the operational process, the bobbin end can be rotated at roller surface, thereby has reduced the wearing and tearing of bobbin and body frame, has improved service life, has guaranteed safe in operation.

Fig. 1 is the structural representation of vertical pay off rack in the prior art;
Fig. 2 is a Facad structure scheme drawing of the present utility model;
Fig. 3 is a construction profile scheme drawing of the present utility model.
The specific embodiment
As Fig. 2, shown in Figure 3, embodiment of the present utility model has the body frame 21 of a tetragonous cone table shape, two root posts 22 are fixed between the base plate and top board of body frame, a four-bar linkage 23 can be upper and lower mobile on column, in the four pipe link mechanisms, be respectively arranged with upper bracket 232, lower bracket 233, nut 234, jacking block 235 on four hinge-points between four connecting rods 231; Be respectively arranged with two pilot holes 236 on upper bracket and the lower bracket, upper and lower support also can move along column is upper and lower by pilot hole and two root post sockets; Be provided with a rhizoid bar 237 between nut and the jacking block, the rear end of screw mandrel withstands on the jacking block, and the thread segment and the nut of screw mandrel are connected, when rotary screw just can be regulated height distance between the upper and lower support; The height and position of whole four bindiny mechanisms is limited by the location pin 24 that is positioned at its below, and the location pin can be inserted in any one knock hole 221 that is arranged on the column.
As shown in Figure 3, the top of upper bracket has a groove 238 that is used for settling bobbin, has been arranged side by side a pair of roller 239 in the bottom of groove.In the unwrapping wire process, the end of bobbin just is placed between two rollers and is supported by two rollers, and bobbin relatively rotates with roller during unwrapping wire like this, and the friction of formation is a friction of rolling, thereby has reduced wearing and tearing.
