Description
Technical field
The utility model relates to electric power conveying technology field, specifically, relates to a kind of cross-arm for concrete wire pole.
Background technology
Current electric power line pole tower is all provided with cross-arm, and the free end of cross-arm is provided with insulator, and trolley wire is installed on the insulator, and the material of cross-arm is mostly metal.Current distribution line has single, double loop and multiloop, and the cross-arm on circuit and insulator are often because track remodelling, corrosion, breakage need to change.The existing cross-arm for concrete wire pole can not be installed very easily, change.
Summary of the invention
Content of the present utility model is to provide a kind of cross-arm for concrete wire pole, and it can overcome certain or some defect of prior art.
According to the cross-arm for concrete wire pole of the present utility model, it comprises support bar and anchorage bar, and support bar and anchorage bar are equipped with on concrete wire pole; Support bar side is provided with support, and one end of anchorage bar is rotated by pivot pin and is arranged on support, and the other end of anchorage bar is provided with the first screw, and support bar and the first screw corresponding position are provided with the second screw; Support bar is provided with the installing hole of 2 rows for installing insulating.
When the utility model is arranged on concrete wire pole, only anchorage bar need be rotated, screw is used support bar and anchorage bar to be engaged on utility poles by the first screw, the second screw, in whole installation process, only need a fastening screw can reach the object of installation, easy to operate, this seems particularly important to work high above the ground.In addition; electric wire is erected on cross-arm by insulator; under cross-arm is operated in the environment of exposing to the weather; the junction of insulator and cross-arm often there will be dead situation of becoming rusty; this can make when insulator is damaged; cannot change it easily; and support bar of the present utility model is provided with the installing hole of 2 rows for installing insulating; this the utility model is possessed insulator installing hole for subsequent use; facilitate the replacing of insulator, the utility model can repeatedly be used.
As preferably, can also be configured with semicircular mounting groove in the middle part of support bar, can also be configured with semicircular clamping slot in the middle part of anchorage bar, mounting groove and clamping slot are defined as the installing hole adapted with concrete wire pole periphery.
The junction of support bar of the present utility model and anchorage bar and concrete wire pole is all designed to arc contact surface, this arc contact surface can be fitted the periphery of concrete wire pole, this structure considerably increases the contact surface of the utility model and concrete wire pole, and what it is such that the utility model can be firm is arranged on concrete wire pole.
As preferably, the inner side of mounting groove can also be provided with the first rubber pad, is provided with the second rubber pad inside clamping slot.
A circle rubber pad can also be provided with between the utility model and concrete wire pole, because rubber has better frictional behaviour, the utility model can be better connected with concrete wire pole.In addition, because rubber has certain elasticity, this makes when anchorage bar and support bar being clamped by screw, and rubber pad can produce an outside elastic force, and what which avoid that the utility model produces because expanding with heat and contract with cold loosens.
In a preferred embodiment of the present utility model, the periphery of anchorage bar is also radially provided with adjusting nut, and because concrete wire pole is taper, adjusting nut can make the utility model be fixed on the differing heights place of concrete wire pole.

Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment 1
As shown in Figure 1, be the cross-arm for concrete wire pole in the present embodiment, its entirety shows it with 100, and it comprises support bar 110 and anchorage bar 120, and support bar 110 and anchorage bar 120 are equipped with on concrete wire pole; Support bar 110 side is provided with support 114, and one end of anchorage bar 120 is rotated by pivot pin 130 and is arranged on support 114, and the other end of anchorage bar 120 is provided with the first screw 121, and support bar 110 and the first screw 121 corresponding position are provided with the second screw 111; Support bar 110 is provided with the installing hole 115 of 2 rows for installing insulating.Be configured with semicircular mounting groove 112 in the middle part of support bar 110, be configured with semicircular clamping slot 122 in the middle part of anchorage bar 120, mounting groove 112 and clamping slot 122 are defined as the installing hole adapted with concrete wire pole periphery.The inner side of mounting groove 112 is provided with the first rubber pad 113, is provided with the second rubber pad 123 inside clamping slot 122.
As shown in Figure 2 and Figure 3, the cell wall of the clamping slot 122 of the present embodiment being radially provided with 2 adjusting screw(rod)s 210, by regulating adjusting screw(rod) 210, the present embodiment can being made to be fixed on the multiple height of concrete wire pole.
As shown in Figure 4, the support 114 in the present embodiment comprises 2 stands be arranged in parallel, each stand is equipped with the slotted eye for installing pivot pin 130, limits the space of settling anchorage bar 120 between 2 stands.
When the cross-arm for concrete wire pole in the present embodiment is arranged on concrete wire pole by user, first mounting groove 112 is fitted in concrete wire pole surface, rotary supporting rod 110, clamping slot 122 is made to be clamped on concrete wire pole surface, use afterwards screw from the first screw 121, second screw 111 by support bar 110 and anchorage bar 120 fastening, thus make that the cross-arm for concrete wire pole in the present embodiment can be firm be arranged on concrete wire pole.Concrete wire pole is taper configurations, i.e. up-thin-low-thick structure, in the present embodiment, by adjustment adjusting screw(rod) 210, the installing hole in the present embodiment not only can be made can to adapt to the different concrete wire pole of thickness, the present embodiment can also be made can be installed on the differing heights place of concrete wire pole.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
