Detailed description of the invention
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of new-type overhead contact line device, is described in further detail this utility model below in conjunction with embodiment.
Embodiment
As shown in Fig. 1 ~ 4, a kind of new-type overhead contact line device, including column 1, the bracket 2 that is vertically set on column, on described bracket, the bottom away from one end of column is provided with positioning support 3, described positioning support is connected with positioning pipe 4, relative angle between positioning pipe and ground level can be adjusted, and on described positioning pipe, one end of remotely located bearing is provided with localizer 5.Described localizer includes being cased with support 51, chute 52, slide block 53 and registration clamp 54, and described support is enclosed within positioning pipe so that can adjust support position on positioning pipe.
Being worth special instruction, described positioning pipe is provided with insulator so that positioning pipe is integrated with location and the function of insulation, combines bracing wire and the positioning pipe effect of insulating in prior art.
Described bracket is arranged on column by the first fixture, and described positioning support is also arranged on bracket by the first fixture.Described first fixture makes bracket removably connect with column, and described positioning support also removably connects with bracket, facilitates maintenance and safeguards.
Chute can be removably connected with by the second fixture bottom described support, in described chute, be provided with slide block so that slide block can be relative to slide, and described slide block is provided with the contact line fixing device that can fix contact line.
Described first fixture and the second fixture all include T-bolt, nut and anchor ear.
In the present embodiment, described contact line fixing device is preferably registration clamp.
Automatic adjusting position can be allowed to one power of slide block when contacting the power produced the when that line expanding with heat and contract with cold.
Described positioning support 3 includes positioning support main body 31, described positioning support main body is the square tube construction of boring, described positioning support main body also includes spring 32, the earrings screw rod 33 being arranged in positioning support, and the structure of described earrings screw rod is the structure being fixedly connected with inverted T shape plate bottom annulus.The inverted T shape plate of described earrings screw rod is pressed in spring top.A part for described positioning pipe is positioned at positioning support body interior, described positioning pipe is positioned at the termination of the one end within positioning support also for cirque structure, described positioning pipe is positioned at the part of the one end within positioning support and earrings screw rod annulus and is jointly installed with the second fixture so that earrings screw rod removably connects with positioning pipe.Described positioning support also includes the 4th fixture, the part that described positioning pipe is positioned within positioning support is connected with positioning support main body also by the 4th fixture, making positioning support is that positioning pipe provides fulcrum 6, make to be formed between positioning pipe 4 and positioning support lever construction, and the lever construction that exists for of spring provides the power of return, the existence of described earrings screw rod makes the power of spring return function can pass to positioning pipe, plays the effect of a connector.Described 4th fixture includes nut and fulcrum screw, described fulcrum screw be provided with screw thread, middle smooth structure for two.
During installation, fix with the first fixture after as required bracket being adjusted to suitable position；It is arranged on bracket after again positioning support, positioning pipe, support, chute and slide block being assembled.The position needed further according to contact line, again is finely adjusted to fix with the relative position of chute to positioning support, positioning pipe, support and slide block and contacts line.
Due in prior art in order to fix the position of contact line, used substantial amounts of bracket and localizer, locating ring and bracing wire so that total is complex, it is the most convenient to install, and too many bracing wire also makes and affects urban look.And from the present embodiment, can be fairly obvious find out, technical scheme described in this enforcement is compared to existing technologies, almost without using bracing wire and substantial amounts of localizer, locating ring, only employ positioning support and i.e. achieve function of the prior art with the chute that can relative slide and slide block, greatly reduce the use of parts, also simplify total, make easy for installation, and do not interfere with urban look.
According to above-described embodiment, this utility model just can be realized well.What deserves to be explained is; on the premise of designing based on said structure; for solving same technical problem; even if some made on this utility model are without substantial change or polishing; the essence of the technical scheme used is still as this utility model, therefore it should also be as in protection domain of the present utility model.
