Abstract
The utility model discloses a cross-pulley device for an erected wire, which comprises a convenient-to-hold insulating rod. The top of the insulating rod is fixedly provided with a bracket. The upper part of the bracket is alternately provided with two parallel lateral plates. A pulley is arranged between the two lateral plates and is used for bearing an erected wire. The cross-pulley device for the wire erection is simple in structure and convenient to carry about and use. By means of the cross-pulley device, both the manpower and material resources are saved. Meanwhile, the extension and the traction of the erected wire can be realized without the construction of any extra crossing frame, and the crossing erection of the wire is realized. In addition, the working efficiency is improved and the construction cost is saved.
Description
Technical field
The aid that uses when the utility model relates to a kind of power circuit and sets up, a kind of cross-line coaster specifically.
Background technology
In power line construction stringing process; often can run into the situation that electric wire and electric wire intersect; in construction stringing operation process; the power circuit below many times can run into the situation of crossing over entrance line, telephone wire etc., in the process of installing electric wiring, can destroy the circuit crust or break circuit to cause damage.
The general crossing frame that adopts is isolated the leap electric wire and is crossed over electric wire now, and crossing frame is the frame structure of being made by the aluminium alloy of steel alloy or lighter weight.The transmission line that sets up due to needs need to move between adjacent two steel towers, and in the process that transmission line moves, to be supported and slippage thereon by crossing frame, crossing frame is not only being carried the weight of transmission line, also and between transmission line produce sliding friction simultaneously, so, the larger frictional force wear damage that crossing frame is easily produced by the transmission of electricity electric wire of slippage; Frictional resistance between transmission line and crossing frame also can cause occurring that transmission line moves difficulty simultaneously, causes the phenomenons such as transmission line stagnation, and then affects construction progress, to construction, makes troubles, and causes its long construction period, and cost is high.
The utility model content
The utility model technical issues that need to address are to provide a kind of simple in structure, easy to use installing electric wiring cross-line coaster.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Install electric wiring and use the cross-line coaster, comprise a convenient insulating bar that grips, the top of described insulating bar is fixedly installed support, and the spaced two blocks of side plates parallel to each other in the top of support, be provided for accepting the pulley that installs electric wiring between biside plate.
Further improvement of the utility model is: the protective layer that is provided for preventing damaged wire in the race of described pulley.
Further improvement of the utility model is: the bottom of described support is fixedly installed one and installs electric wiring and the crotch that is in contact with one another by the leap electric wire be used to preventing.
Further improvement of the utility model is: described insulating bar is expansion link.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is simple in structure, carry, easy to use, simple to operate, saved manpower and materials, only the electric wire that will set up need be placed in to the race of pulley, the electric wire that need to set up by the flexible lifting of insulating bar, just can will install electric wiring and cross over existing transmission line, at the another side of being crossed over electric wire, draw, the rotation by pulley reaches the conveying purpose that installs electric wiring, and completes the leap of the electric wire that need to set up.After using the utility model, newly-built crossing frame, just can realize that the leap of electric wire is set up again, improved operating efficiency, saved operating expenses.
In the race of pulley, protective layer is set, the wire outer skin when tracting that prevents from installing electric wiring is damaged.The crotch that arranges at cylinder place, support bottom can hold onto the electric wire of being crossed over temporarily in the utility model use procedure, will install electric wiring and be crossed over electric wire and separate, and prevents that both from causing damaged wire because of contact friction.
The insulating bar that arranges is convenient to be gripped, insulation characterisitic has guaranteed staff's safety simultaneously, insulating bar is arranged to expansion link, operating personnel can regulate according to the height of the transmission line of being crossed over, in operating process, be not subjected to limitation in height, on ground, just can directly cross over setting up of electric wire, the scope of application is wider.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further details:
Install electric wiring and use the cross-line coaster, as shown in Figure 1, comprise insulating bar 3, support 2 and pulley 1.Described support 2 tops arrange pulley 1, and the bottom of support 2 is fixedly connected with the top of insulating bar 3.
The top of described support 2 is the U-shaped bifurcation structure, and namely the top of support 2 is arranged at intervals with two blocks of side plates parallel to each other, the bottom of two blocks of side plates by with two blocks of side plates all vertical base plate be connected.Between two blocks of side plates, be fixedly installed a back shaft 22, on back shaft 22, socket arranges pulley 1.Described pulley 1 is be used to accepting the electric wire that need to set up; the electric wire that in operating process, needs is set up is in the race to pulley 1; for the protection electric wire; prevent that the friction in unfolding and distraction procedure of electric wire skin is impaired; in the race of pulley 1, cover rubber layer is set, also can select other elastomeric material as protective layer.The bottom of support 2 is tube-in-tube structure, and the top of described sleeve is connected with the base plate of U-shaped bifurcated, and a crotch 21 is set on the outer wall of sleeve, and as shown in Figure 2, the plane at the plane at the center line place of crotch 21 and the center line place of back shaft 22 is orthogonal.In use, crotch 21 can install electric wiring needs and keep apart with the electric wire of being crossed over, and prevents from suffering damage because between electric wire, being in contact with one another friction.
The sleeve of support 2 bottoms and the top of insulating bar 3 are fixedly sleeved, the convenient gripping of described insulating bar 3, and for improving general applicability of the present utility model, the limitation in height that is not installed electric wiring, insulating bar 3 is arranged to expansion link, also can be pegged graft and be formed by some sections quarter butts.Utilize the safety that the insulation characterisitic of insulating bar 3 can the safeguard work personnel.
