Description
Technical field
The present invention relates to power supply construction field, particularly relate to a kind of cable drum and manually draw aid.
Background technology
Along with the development of China's economy, the range of application of power equipment is increasingly wider, and the laying work of cable is an indispensable ring in power transmission, in some large-scale electric power facilities are built, cable make consumption and to lay work very big.At present, when cable work is laid in power system, mainly having two kinds of methods, one is to adopt crane unwrapping wire, and another kind is dependent on cable unreeling rack, is placed on by cable hank on rotating pay off rack, with manually realizing unwrapping wire.Adopt crane unwrapping wire, owing to laying environmental limitation in ground, crane unwrapping wire cannot be realized in some places, artificial unwrapping wire can only be adopted, when the actual job of artificial unwrapping wire, it is usually and directly holds cable with hands and lay, owing to some cables are relatively thick, the bad grasp of hand, simultaneously, in unwrapping wire process, cable can rotate and stubborn strength, brings more trouble to artificial laying.The Chinese patent that application publication number is CN104283158A discloses a kind of portable wire dispenser, this wire dispenser includes one with the axle sleeve of handle, by bearing hinge connection one rotating shaft in axle sleeve, rotating shaft lower end hinged one even root, is matched by jointed shaft hinged one and connecting rod and blocks the U-shaped lock sleeve of cable in connecting rod lower end.This wire dispenser eliminates the stubborn strength phenomenon of cable to a certain extent, but when connecting rod and cable are 90 ° of angles, rotating shaft just cannot realize rotating, thus cable self cannot be eliminated rotate the stubborn strength produced, simultaneously, handle in this wire dispenser, when cable laying, uses and not convenient, because handle is straight-bar, when laying, need between palm and handle, there is enough frictional force just stretchy cable, for the user that some arm strength are little, it is impossible to hold handle to pull cable.
Summary of the invention
It is an object of the invention to provide a kind of cable drum and manually draw aid, this aid simple in construction, easy to use, in unwrapping wire process, it is possible to cable self is completely eliminated and rotates the stubborn strength produced, then avoid the damage because cable is caused by winding.
This invention address that its technical problem is adopted the technical scheme that: a kind of cable drum manually draws aid, including handle, support transverse slat, upper hold down gag and lower support device, described handle is hinged on the one end of described support transverse slat;
The medium position of described support transverse slat arranges a tapped through hole, described upper hold down gag includes threaded rod and is movably arranged on the top board below described threaded rod, being provided with two on described top board can free rolling roller, described threaded rod is nested with in described tapped through hole, and arranges a transverse slat in the upper end of described threaded rod;
Described lower support device includes inverted " t " type connecting rod and is disposed in parallel in two arc support rods below described inverted " t " type connecting rod, described inverted " t " type connecting rod is arranged on the one end of described support transverse slat and is positioned at the lower section of described handle, two groups of rolling support devices it are provided with between two described arc support rods, described rolling support device includes the two ends support bar with annular through groove, and the crooked radian of described annular through groove matches with the crooked radian of described arc support rod.
Preferably, one it is fixedly installed with the hollow loop bar of some through holes below the one end of described support transverse slat, the montant of described inverted " t " type connecting rod is nested with in described hollow loop bar, and described inverted " t " type connecting rod is fixed on described hollow loop bar by bearing pin by the through hole arranged on the through hole arranged on described montant and described hollow loop bar.
Further, it is fixedly installed a reinforcement at the angular position of described hollow loop bar Yu described support transverse slat.
Preferably, a sidewall of described support transverse slat arranges a hollow circular-tube.
Preferably, a limiting through hole running through described annular through groove is respectively set at the two ends of described support bar, two described arc support rods are each provided with several grafting through holes that arcuately support bar circumferential direction is distributed.
Further, all it is nested with a bearing at the two ends of described support bar, and two described bearings are isolated by the shaft shoulder being arranged in the middle part of described support bar.
Further, described support bar is nested with the rolling sleeve pipe that an energy relative support bar is freely rotatable.
Preferably, ringwise, two described rollers are oppositely arranged on the medial wall of described top board described top board.
The invention has the beneficial effects as follows:
1, the distance between upper hold down gag and lower support device can be changed by the threaded rod in the upper hold down gag of rotation, to adapt to the clamping with the cable of different thicknesses degree, simultaneously, enable to top board by rotating threaded rod and cable is tightly pressed on arc support rod, in order to workmen drags cable and moves.
2, the distance between two rolling support devices on two arc support rods can regulate along the circumferential direction of arc support rod, in order to rolling support device can the fineness of better appropriate cable.
3, it is arranged on the roller on top board and the bearing being arranged on support bar or hollow bushing all can rotate freely; in unwrapping wire process; if cable produces to twist strength the phenomenon rotated; then roller and bearing or hollow bushing enable to cable and easily realize rotation; thus the stubborn strength of cable can be eliminated, cable is served certain protective effect.
4, hollow loop bar is connected by the mode of grafting with inverted " t " type connecting rod, by adjusting the relative distance between inverted " t " connecting rod and hollow loop bar, it is possible to meet the use requirement for height that workmen is different.
5, when drawing staff and being more, it is possible to support being punctured into cross bar in the hollow circular-tube that transverse slat side is arranged, cable can be lifted by two staff of cross bar and move forward.
