Embodiment
For the technical scheme of technical problem that the present invention is solved, employing and the technique effect that reaches clearer, below in conjunction with accompanying drawing, the technical scheme of the embodiment of the present invention is described in further detail, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those skilled in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 and Fig. 2 are respectively the partial enlarged drawings at A place in the structural representation of a kind of arrester handcart of providing of the specific embodiment of the invention and Fig. 1.
As shown in the figure, this arrester handcart, comprises vehicle frame 1 and lightning arrester 2, on described vehicle frame 1, busbar 3 is installed, the front end of described busbar 3 is connected with insulator 4, and the front end of described insulator 4 is connected with conductive contact arm 5, and the rear end of insulator 4 is connected with the first support 51; The second support 11 is installed on described vehicle frame 1; Described the first support 51 and the relative embedded hole 511 that offers on the second support 11; On described lightning arrester 2, be provided with elastic extension structure, the two ends of lightning arrester 2 are respectively arranged with projection 21, and the projection 21 of lightning arrester 2 one end embeds in the embedded hole 511 of the first support 51, and the projection 21 of the other end embeds in the embedded hole 511 of the second support 11.The elastic extension structure of described lightning arrester 2 is metal spring.The periphery of described metal spring is arranged with guard circle, and described guard circle is fixed on lightning arrester 2 one end near the first support 51.Described protruding 21 vertical height is 1-2CM.The edge at described protruding 21 top is provided with chamfering.Described embedded hole 511 is the blind hole that opening is relative.The degree of depth of described blind hole is less than the height of projection 21.
By two supports are set, on support, correspondence is offered embedded hole, the lightning arrester with elastic extension structure is set simultaneously, lightning arrester is snapped between two supports by the tension force of elastic extension structure, in the time of installation and maintenance, only elastic extension structure need be compressed, can easily install and take out, it is very convenient to operate, and improves dismounting efficiency.In the present invention, lightning arrester 2 can be considered as three sections, respectively the each functional section in two ends and middle compression section, the wherein namely position at elastic extension structure place, compression section, in the time that lightning arrester 2 need to be changed, directly by two ends to intermediate compression, the projection 21 at lightning arrester 2 two ends is exited in embedded hole 511, take the lightning arrester 2 breaking down away; When installation, by aforesaid operations backward implement just can, the two ends that the elastic force of elastic extension structure itself will order about lightning arrester 2 are embedded in embedded hole 511, keep installation stablize.
Elastic extension structure, except being metal spring, can be also that conducting resinl etc. has flexible parts.The concrete structure of spring in the prior art more explanation, repeats no more herein.The setting of guard circle is not only in order to protect spring, be also simultaneously prevent lightning arrester 2 after installation under elastic force effect for a long time, because the elastic force of spring itself is inhomogeneous, cause the lateral thrust of spring, thus the potential safety hazard of bringing.Because the arrester handcart overwhelming majority time all keeps inactive state, only have when safeguarding or overhaul and can move, so being set to 1-2CM, the vertical height of projection 21 can guarantee stable state.Preferably, described protruding 21 vertical height is 1.5CM.The setting of chamfering is for more smooth and easy in the time embedding.The degree of depth of described blind hole is less than the installment state that projection 21 height contributes to keep lightning arrester 2, prevent because elastic compression structure use for a long time with elastic fatigue cause loosening.
Preferably, the periphery of described metal spring is arranged with guard circle, and described guard circle is fixed on lightning arrester 2 one end near the second support 11.
Guard circle be fixed on said lightning arrester 2 above two functional sections any one section all can, be arranged on spring and be also fine in fact, just allow guard circle along with the compression movement of spring may cause operation inconvenience.
Preferably, one section of described lightning arrester 2 is provided with the axis of guide, and other end correspondence is provided with pilot hole, and the described axis of guide stretches into pilot hole through metal spring.
The axis of guide can guarantee that lightning arrester 2 can only axially change in the process of maintenance elastic force better.The axis of guide can also be designed to the metal axis of guide simultaneously, and now the axis of guide also can be used as wire, and in this state, metal spring can further replace with elastic caoutchouc.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
