Abstract
The utility model relates to a high -low pressure distribution crane span structure turns to elbow belongs to high -low pressure distribution equipment field. Be equipped with quiet arm, its characterized in that, the one end of quiet arm is through pivot and swing arm one end hinge to during the pivot is on the calm arm equipartition have a round pinhole, bolt hole and bolt hole have down been processed respectively to the upside of swing arm and downside, go up positioning bolt and down positioning bolt pass the pinhole respectively and fix under last bolt hole reaches in the bolt hole. The utility model discloses simple structure through adjustment crane span structure angle of bend, realizes that the multi -angle turns to the connection, reduces constructor's work load and working strength, improves bridge connection's flexibility, commonality.
Description
Technical field
This utility model is related to high and low voltage electric distribution apparatus field, is a kind of high and low voltage electric distribution of adjustable angle in detail
Crane span structure turns to elbow.
Background technology
It is known that the crane span structure using in high-low pressure cable distribution, greatly, specification is many, in-site installation complicated condition for quantity,
Often it is forced because hiding the barriers such as wind, water pipe, building beam column to do break-in adjustment, after needing field measurement data, turn prefabrication
Or onsite application lead directly to cutting, welding production, waste time and energy, seriously drag slow project progress, and presence scene get angry safety hidden
Suffer from.
Content of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of box-type substation door-plate opening device, structure
Simply, practical, flexible for installation, easy.
This utility model solves its technical problem and be the technical scheme is that a kind of high and low voltage electric distribution crane span structure steering is curved
Head, is provided with quiet arm it is characterised in that one end of quiet arm is hinged with swing arm one end through rotating shaft, uniform on quiet arm centered on rotating shaft
A circle pin-and-hole, the upside of swing arm and downside is had to be machined with upper bolt hole and lower bolt hole, upper bolt and lower positioning spiral shell respectively
Bolt is each passed through pin-and-hole and is fixed on upper bolt hole and lower bolt in the hole.
The beneficial effects of the utility model are that structure is simple, by adjusting crane span structure angle of bend, realize multi-angle and turn to even
Connect, reduce workload and the working strength of workmen, improve motility, the versatility that crane span structure connects.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure 1. swing arm, 2. goes up bolt, 3. pin-and-hole, 4. rotating shaft, 5. descends bolt, 6. quiet arm.
Specific embodiment
In FIG, this utility model is provided with quiet arm 6, and one end of quiet arm 6 is hinged with swing arm 1 one end through rotating shaft 4, with rotating shaft 4
Centered on be evenly equipped with a circle pin-and-hole 3 on quiet arm 6, the upside of swing arm 1 and downside are machined with upper bolt hole and lower bolt hole respectively, on
Bolt 1 and lower bolt 5 are each passed through pin-and-hole 3 and are fixed on upper bolt hole and lower bolt in the hole.
Swing arm 1 is rotated to proper angle around rotating shaft 4 by this utility model according to site obstructions situation, using upper fixed
Position bolt 1 and lower bolt 2 are fixed, and complete angular transformation.
