Description
Technical field
The utility model relates to a kind of device installed electric wiring, the top skating car installed electric wiring when being specially a kind of power circuit block.
Background technology
Electric power system needs when installing electric wiring to carry out block to transmission line sometimes, when the circuit set up is across 110kV and above power circuit and provincial and above highway, in order to the operation of the normal conveying and traffic that do not affect electric power, need to set up temporary cross arm on the steel tower on highway, railway or power circuit both sides, support across electric wire, cable rack is high, hang to prevent electric wire and get off to affect power circuit and traffic.Temporarily temporary cross arm is arranged on steel tower.In the process of erection cable, in order to when reducing to pull electric wire, temporary cross arm needs to set up coaster on temporary cross arm to the frictional resistance of electric wire usually.360 ° of coasters disclosed in patent of invention CN103199458A, by pulley spindle, pulley is arranged on U-shaped pulley yoke, but pulley yoke flushes with pulley top, pulley yoke does not play the effect be limited in by electric wire on pulley, in electric wire pulling process, electric wire is easy to split away off from pulley rub with temporary cross arm, coaster is performed practically no function ineffective.
Utility model content
The utility model is to provide a kind of block top skating car, solves electric wire when installing electric wiring contacts easily wearing and tearing problem with cross-arm.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Block top skating car, comprises the base that is connected with the temporary cross arm on steel tower and is connected to base upper roller frame, and described base comprises the Connection Blocks that two are inverted U-shaped structure, is provided with bolt between the biside plate at Connection Block lower openings place; The supporting bracket that described turning rolls comprises both sides be connected the substrate of supported on both sides plate bottom and be connected to the roller bearing of supported on both sides plate middle and upper part, roller bearing is arranged a roller; The two ends of described substrate are fixedly connected between the top board of two Connection Blocks respectively.
Further improvement of the utility model is: the corner that supporting bracket is connected with substrate is provided with one and consolidates plate with supporting bracket and substrate all in acute angle; The substrate of turning rolls is fixed on the centre position of Connection Block top board.
Further improvement of the utility model is: described turning rolls is with roller bearing, supporting bracket and consolidate plate, consolidate plate and substrate, connection between substrate with base all adopts and weld.
Owing to have employed technique scheme, the technological progress acquired by the utility model is:
The utility model coaster is provided with roller, and when the electric wire set up streaks from cross-arm, roller rolls together along with pulling of electric wire, decreases the frictional force between roller surface and wire surface, reduces the wearing and tearing to electric wire.
Roller bearing of the present utility model is arranged at the middle and upper part of supporting bracket, supporting bracket is made to exceed roller certain altitude, when the line direction between two cross-arms is departed from the direction pulling electric wire, the supporting bracket that both sides exceed can play the effect of baffle plate, electric wire is limited between two supporting brackets, ensure that electric wire can not slide from roller, play the effect of slip-off preventing.
The U-shaped structure of Connection Block of the present utility model, and be provided with bolt in the bolt hole on the side plate of Connection Block, two of a coaster Connection Block can be across on cross-arm during block and use, and bolt can play fixing effect to coaster, ensure that coaster can not come off from cross-arm because of pulling of electric wire.
Corner between supporting bracket of the present utility model and substrate is provided with and consolidates plate, consolidate plate and can play to supporting bracket and substrate the effect supporting and consolidate, supporting bracket and substrate and consolidate plate and form a stable triangle, play an effect strengthened to the structure of whole turning rolls.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Block top skating car, as illustrated in fig. 1 and 2, comprises the base 3 on the temporary cross arm 9 that is connected on steel tower and the turning rolls be connected on the base 3.As shown in Figure 1, two Connection Blocks 8 in inverted U-shaped structure composition base 3 jointly, there are two side plates at Connection Block 8 lower openings place, the bolt 6 for fixed idler whell frame is provided with between these two side plates, bolt 6 penetrates from the bolt hole a side plate of Connection Block 8, passes from the bolt hole of another relative side plate.Described turning rolls is made up of three parts: supporting bracket 1, substrate 7 and roller bearing 5; Supporting bracket 1 is positioned at the both sides of turning rolls, totally two, one, every side; Substrate 7 between two supporting brackets 1, for connecting the supporting bracket 1 of both sides; The centre of two supporting brackets 1 of roller bearing 5 on turning rolls, is welded in the middle and upper part of supported on both sides plate 1.Roller bearing 5 is arranged a roller 4 slightly short with roller bearing 5 length, when using top skating car, can be coated with a little lubricating oil between roller 4 and roller bearing 5 surface facilitates roller 4 to rotate, because roller bearing 5 is positioned at the middle and upper part of supporting bracket 1, therefore supporting bracket 1 exceeds roller 4 certain altitude, therefore, when electric wire pulls, the supporting bracket 1 that both sides exceed can play the effect of baffle plate.The two ends of substrate 7 are fixedly welded on the top board centre position of two Connection Blocks 8, the symmetrical structure that therefore turning rolls is is axle with substrate 7.The supporting bracket 1 of both sides and the corner of substrate 7 have one all to weld with supporting bracket 1 and substrate 7 acutangulately to consolidate plate 2, consolidate plate 2 and form a right-angled triangle with supporting bracket 1 and substrate 7 respectively.
The course of work of the present utility model is as follows:
As shown in Figure 2, by two Connection Blocks 8 on the base 3 of top skating car across cross-arm 9, and the bolt hole be each passed through with two bolts 6 on the side plate on Connection Block 8, and pass from the bolt hole on each self-corresponding side plate, nut is fixed on bolt 6 and tightens, now top skating car is fixed on the top of cross-arm 9 firmly.Then passed above roller 4 by pull rope, in the passage that the supporting bracket 1 electric wire being pulled roller 4 and both sides forms, continue to pull electric wire, by electric wire through the top skating car on the temporary cross arm 9 on opposite, road, the work of temporary erection electric wire can be completed.
