Abstract
The utility model provides an intermediate joint of an inner contact tubular bus, which is connected with a first tubular bus and a second tubular bus. The intermediate joint comprises a liner tube and a stainless steel hoop; the outer diameter of the liner tube is equal to the inner diameters of the first and the second tubular buses; the liner tube is placed in the end parts of the first and the second tubular buses; two or more equant openings are formed upwards at the connection part of the first and the second tubular buses in the direction parallel to the axis of the connection part; the stainless steel hoop is sleeved outside the connection part of the first and the second tubular buses; an opening parallel to the axial direction of the stainless steel hoop is formed on the stainless steel hoop; the stainless steel hoop can be tightened toward the inner part of the opening under the action of external force; and after tightened, the opening can be closed by a welding seam. The intermediate joint provided by the utility model adopts the liner tube and the hoop to be connected with the tubular buses, and achieves splicing through the welding seam in the axial direction; and the electric conduction between the tubular buses is achieved through the liner tube, and the joint fixation is achieved through the hoop. The intermediate joint is simple to mount and ensures reliable connection.
Description
[technical field]
The utility model relates to the pipe bus, relates in particular to a kind of transition joint of interior touch pipe bus.
[background technology]
At present, domestic and international all kinds of busbar is managed bus when mounted and is continued to adopt dual modes more.
First kind be in adopting bus lined duct again the mode of welding end surface realize.Because of bushing pipe is a matched in clearance, end face is the circumference welding, and the on-site construction operations difficulty is big, and the electric conductivity of joint is not easy to guarantee.
Another kind is to adopt the firm mode of two-sided anchor ear bolt.The profile of anchor ear is bigger and irregular, limited the scope of application that bus is installed, firm is the standard bolt connection, and the pipe bus is in operation and is subjected to the electric power vibration influence can cause bolt looseness, increase failure rate and repair and maintenance difficulty, and had electrical safety hidden danger.
[utility model content]
In view of this, be necessary to provide a kind of installation simple, connect reliably in the transition joint of touch pipe bus.
Touch pipe bus transition joint in a kind of, described interior touch pipe bus transition joint connect the first pipe bus and the second pipe bus.Described transition joint comprises bushing pipe and stainless steel anchor ear, the external diameter of described bushing pipe and described first, the internal diameter of the second pipe bus equates, described bushing pipe is built in described first, the end of the second pipe bus, described first, offer the two or more openings of five equilibrium on its parallel axes direction of upper edge, junction of the second pipe bus, described stainless steel anchor ear is enclosed within described first, outside the junction of the second pipe bus, described stainless steel anchor ear is provided with the opening with its axially parallel, described stainless steel anchor ear can tighten up in described opening under external force, and described opening can be sealed by weld seam after tightening up.
Preferably, the width of described opening is 4～6 millimeters, and described opening cuts off described stainless steel anchor ear along its length direction.
Preferably, the width of the opening of described pipe bus is 2～4 millimeters.
Bushing pipe and anchor ear tube connector bus are adopted in the transition joint of touch light bus in of the present utility model, realize continued access by weld seam vertically.Bushing pipe is realized the conduction between the pipe bus, and anchor ear is realized the fixing of joint.This transition joint installs simply, connects reliable.
[description of drawings]
Fig. 1 is the schematic diagram of touch pipe bus transition joint in the preferred embodiment of the present utility model.
[embodiment]
For understanding the utility model better, the embodiment to utility model is described in detail below with reference to accompanying drawing.
See also Fig. 1, the interior touch pipe bus transition joint of preferred embodiment of the present utility model comprises pipe bus internal lining pipe 1, stainless steel anchor ear 2, pipe bus 3 and pipe bus 4, and this transition joint is used for tube connector bus 3 and pipe bus 4.Offer an opening (part that mark 5 is covered among the figure) with its axially parallel on stainless steel anchor ear 2 walls, opening cuts off stainless steel anchor ear 2 along its length direction.Connected two sections pipe buses 3 and 4 have two or more openings at the first-class branch of connecting portion, and the opening on the pipe bus 3,4 need be prevented the chamfering rounding processing of point discharge.In the illustrated embodiment, the A/F of stainless steel anchor ear 2 is 4～6 millimeters, and the A/F on the pipe bus 3,4 is 2～4 millimeters.
Use above-mentioned in the transition joint of touch pipe bus come tube connector bus 3 and at 4 o'clock, at first outside dimension is equaled to manage bus 3,4 internal diameter sizes and be built in two sections and have the pipe bus 3 of axially open and 4 connecting portion, and adjust link position with the bushing pipe 1 of pipe bus 3,4 same materials.Then, entangle the connecting portion of two sections pipe buses 3 and 4 with the stainless steel anchor ear 2 that has an axially open after, tighten up stainless steel anchor ear 2 with special fixture at circumferencial direction.Opening with stainless steel anchor ear 2 pipe bus 3,4 is connected closely with bushing pipe 1 after welds formation weld seam 5, to guarantee the grip force of this joint.Can polishing will be carried out outside the stainless steel anchor ear 5 after the welding.After the polishing,, just can directly carry out next step installation if pipe bus 3,4 is the aluminium-alloy pipe bus; If pipe bus 3,4 is insulated copper (aluminium) pipe bus, employing is preset the insulation shielding tube and is carried out carrying out next step installation after the insulation processing.
The transition joint of touch pipe bus has the following advantages compared to syndetons such as adopting traditional end face welding or bolt in above-mentioned: connect reliably, electric contact is good, and electric conductivity is strong; Blank area smooth in appearance, contact are closely; Be difficult for loosening during operation; Can adapt to the cold and hot contraction of running; Fitting operation is simple, adapts to on-the-spot installation requirement.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
