Description
(1) technical field
This utility model relates to building engineering field, particularly to a kind of unwinding rack used for construction site.
(2) background technology
Pay off rack is widely used in various construction, such as power construction, municipal construction etc., and its effect is need to
The first dish such as the various cables wanted is good, is then easy to unwrapping wire, wiring in work progress.It generally comprises a bracing frame, has
Bracing frame can lift, and bracing frame has individual rotating shaft, is entangled in advance in rotating shaft by cable etc., at slowly unwrapping wire during construction.Existing
In some pay off racks, the most it is not easy to movement, is required for vehicle transport, very inconvenient.
(3) summary of the invention
This utility model is in order to make up the defect of prior art, it is provided that the job site unwrapping wire of a kind of convenient transport
Frame.
This utility model is achieved by the following technical solution:
A kind of unwinding rack used for construction site, including the bracing frame being made up of two supports, bracing frame is provided with rotating shaft, and it is special
Levying and be: described support includes bottom girder, be provided with the castor that belt wheel is stopped below described bottom girder, threaded on described bottom girder have longitudinal spiral shell
Bar, described longitudinal screw upper end is provided with circular capstan winch, and threaded on described longitudinal screw have hold-doun nut, described hold-doun nut
Being positioned at above bottom girder, described longitudinal screw lower end pivotably connects horizontal control beam, and the two ends of described control beam are cut with scissors respectively
Being connected to extension type contact to earth foot, the described extension type foot that contacts to earth is hinged on the lower section of bottom girder, and the described scalable foot that contacts to earth includes touching
Bar and contact to earth foot outer tube in lower margin, described in contact to earth in foot bar and contact to earth sliding extension can occur between foot outer tube, described in contact to earth
The part of contacting to earth of foot outer tube is provided with lug tooth.
The beneficial effects of the utility model are:
This utility model wind loading rating is strong, moves, brakes conveniently, and brakes makes simple, easy to operate, has the strongest
Practicality.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described.
Fig. 1 is side-looking structural representation of the present utility model；
Fig. 2 is vertical screw rod and the annexation schematic diagram controlling beam.
In figure, 1 bottom girder, 2 supports, 3 castors, 4 longitudinal screws, 5 circular capstan winches, 6 hold-doun nuts, 7 control beams, 8 lug tooths,
9 contact to earth bar in foot, and 10 contact to earth foot outer tube, 11 rotating shafts.
(5) detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1 and Figure 2, this kind of unwinding rack used for construction site, including
The bracing frame being made up of two supports 2, bracing frame is provided with rotating shaft 11, and support 2 therein is by bottom girder 1 and two vertical beams or two
Root cant beam forms, and is provided with the castor 3 that belt wheel is stopped in the lower section of bottom girder 1, it is simple to walking；Longitudinal direction threaded on bottom girder 1
Screw rod 4, longitudinal screw 4 is longitudinally through bottom girder 1, and longitudinal screw 4 upper end is provided with circular capstan winch 5, and threaded on longitudinal screw 4 have
Hold-doun nut 6, hold-doun nut 6 is positioned at above bottom girder 1, and longitudinal screw 4 lower end pivotably connects horizontal control beam 7, the most just
Being to say that control beam 7 can rise or fall under the drive of longitudinal screw 4, the two ends of control beam 7 have been respectively articulated with extension type and have touched
Lower margin, the extension type foot that contacts to earth is hinged on the lower section of bottom girder 1, and the scalable foot that contacts to earth includes contacting to earth bar 9 and the foot outer tube that contacts to earth in foot
10, bar 9 and contact to earth sliding extension can occur between foot outer tube 10 in the foot that contacts to earth, the part of contacting to earth at the foot outer tube 10 that contacts to earth is provided with
Lug tooth 8.Its fixation procedure is as follows: first steps on wheel and stops and make castor 3 not be rotated further by, and then turns circular capstan winch 5 and makes longitudinal spiral shell
Bar 4 declines, and controls beam 7 and declines under the drive of longitudinal screw 4, is constant owing to controlling the length of beam 7, therefore controls beam 7
The pin joint of two ends and the scalable foot that contacts to earth move along a straight line at above-below direction, this allows for the scalable foot that contacts to earth and necessarily receives
Contracting, their lower end is moved respectively inwards, so that lug tooth 8 is in close contact with ground, then tightens hold-doun nut 6, bottom girder 1
Just it is fixed on ground.
In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
