Abstract

Conflux method the present invention relates to a kind of pre- astute and able unit ground wire of spiral, 1）The bus-bar prepared is found into appropriate location, selection is most short with conduction brush line bank air line distance and the vacant lot of the enough support installations in locus disposes, and makes support and fixation；2）The bus-bar of preparation is rack-mount, and insulation is carried out, being connected between bus-bar and fixed support needs to be processed with insulating materials；3）Ground wire cable the end of a thread that welding machine is picked out is placed on bus-bar lower end and presses joint, then the cable of preparation has been measured into length and has pressed joint, two pieces of bus-bars are connected with ready-made cable；4）Distance between bus-bar and welding bottom line brush terminal plate is measured, and connecting line is made with cable, ground wire brush folding need to be considered during making, connection line length will carry out surplus；5）Connecting cable and earthed brush terminal plate are attached, all bolts tighten；6）The insulating properties of all insulated parts is checked, is completed if no problem.

Description

The pre- astute and able unit ground wire of spiral confluxes method

Technical field

Conflux method the present invention relates to a kind of ground wire, and in particular to a kind of pre- astute and able unit ground wire side of confluxing of spiral Method, belong to astute and able method and technology field.

Background technology

In the pre- astute and able production process of two-step method, applicant has carried out multiple improvement to production technology, smoothly completes Production task.We have accumulated many two-step methods in the production process of this order（It is pre- astute and able）The experience of production is with pair setting Standby, process modification idea, we have found that the product of astute and able production has certain deficiency, such as steel pipe in daily production B ends（Open arc end）The outside shaping of weld seam is than A ends（Blow-out end）Have differences, the weld seam at B ends is normal weld, but A ends are welded Shaping is narrow and high outside the weld seam of seam, occurs when serious to fill up, the shortcoming such as undercut.The pre- astute and able machine of spiral of the technical scheme The ground wire integration technology of group is exactly to solve this problem and caused techniques and equipment improvement.

The content of the invention

The present invention is exactly for technical problem present in prior art, there is provided a kind of pre- astute and able unit ground wire of spiral Conflux method, the technical scheme is integrated using interior outside weld welding earthed brush to solve original equipment present in welding process not Foot, the standard for meeting production technology.

To achieve these goals, technical scheme is as follows, and a kind of pre- astute and able unit ground wire of spiral confluxes Method, it is characterised in that 1）The bus-bar prepared is found into appropriate location, the selection for position is selected in line with the principle of saving The vacant lot placement of the enough support installations in and locus most short with conduction brush line bank air line distance is selected, field fabrication support is simultaneously solid It is fixed；2）The bus-bar of preparation is rack-mount, and insulation is carried out, needs insulation is connected between bus-bar and fixed support Material is processed, and insulation must be carried out between support and bus-bar, and it is then failure not carry out whole transformation project such as insulation；3） Ground wire cable the end of a thread that welding machine is picked out is placed on bus-bar lower end and presses joint, then cable will be prepared has measured length and press to connect Head（Made according to the physical length between two pieces of bus-bars）, two pieces of bus-bars are connected with ready-made cable；4） Distance between bus-bar and welding bottom line brush terminal plate is measured, and connecting line is made with cable, need to consider that ground wire brush is opened during making Close, connection line length will carry out surplus, because the position of bus-bar is fixed so we have welded when surplus length is considered Length required under conduction brush closure state is defined when connecing minimum pipe, and specific length need to be showed due to site operation position difference Surveyed field）；5）Connecting cable and earthed brush terminal plate are attached, all bolts tighten；6）Check all insulation divisions The insulating properties divided, is completed if no problem.

Relative to prior art, the invention has the advantages that, present spiral fine welding production line it is commonly used be classification The mode of connection of formula, this mode are restricted due to the length of conduction brush connecting plate, it may appear that the situation of cable capacity deficiency, shadow The stability and seam center, quality of welding process are rung, astute and able unit ground wire brush confluxes method, effectively solves because ground wire holds Amount, the mode of connection bring the influence to welded seam with being distributed, and potential is not present between the interior external welding scrubbing brush after improving Difference, there is preferable lifting for the stability of welding system, welding quality is also effectively guaranteed.Stability and welding quality Lifting caused by be product first-time qualification rate rising, have very big facilitation to increase line production capacity.

Brief description of the drawings

Fig. 2 is copper bus structures schematic diagram；

In figure：The copper bus-bars of 1-, 2- insulating bushings, 3- insulation spacers, 4- press the copper Wiring nose of cable.

Embodiment：

In order to deepen the understanding of the present invention, the present embodiment is described in detail below in conjunction with the accompanying drawings.

Embodiment 1：Referring to Fig. 1, Fig. 2, a kind of pre- astute and able unit ground wire of spiral confluxes method, and 1）The remittance that will be prepared Stream row 1 finds appropriate location, and our the principle selections and conduction brush line bank air line distance in line with saving is selected for position The vacant lot of the enough support installations in most short and locus is put, and field fabrication support is fixed；2）The bus-bar 1 of preparation is arranged on branch On frame, and insulation is carried out, being connected between bus-bar and fixed support needs to be processed into as shown in figure 1 above with insulating materials, support Insulation must be carried out between bus-bar, it is then failure not carry out whole transformation project such as insulation）；3）Welding machine is picked out Ground wire cable the end of a thread be placed on bus-bar lower end and press joint, then cable will be prepared measured length to press joint, according to two pieces Physical length between bus-bar is made, and two pieces of bus-bars are connected with ready-made cable；4）Measure bus-bar with Distance between bottom line brush terminal plate is welded, and connecting line is made with cable, ground wire brush folding need to be considered during making, connects line length Surplus is carried out, because the position of bus-bar is fixed so conduction brush when having welded minimum pipe when surplus length is considered Length required under closure state is defined, and specific length needs scene to be surveyed due to site operation position difference；5）Will be even Connect cable to be attached with earthed brush terminal plate, all bolts tighten；6）The insulating properties of all insulated parts is checked, if no problem Then complete.

It should be noted that above-described embodiment, is not used for limiting protection scope of the present invention, in above-mentioned technical proposal On the basis of made equivalents or replacement each fall within the scope that the claims in the present invention are protected.
