Abstract
A combined sealing structure is mainly applied to sealing pipelines and cables of a cab and a machine room of an electric locomotive. A mounting plate 1 is fixed on a partition board 2 through a mounting bolt 8, a steel tube 3 is fixed on the mounting plate 1, a cable or pipeline 5 penetrates through the steel tube 3, the steel tube is filled with rubber 4, two ends of the rubber 4 are provided with clamping plates 6, and the clamping plates clamp the rubber 4 by clamping bolts 7. Sealing adhesive tapes are disposed between the four edges of the mounting plate 1 and the partition board 2 for sealing. The rubber 4 is ethylene-propylene- diene-terpolymer rubber. Each clamping plate 6 is a semi-circular plate. The semi-circular plates are convenient to demount and mount. The combined sealing structure has the advantages that combination and adaptability are high; sealing is high; maintenance is facilitated, and operation is simple; and economy and safety are high.
Description
Technical field
The utility model relates to a kind of sealing configuration, relates in particular to a kind of locomotive combined seal structure.
Background technique
Electric locomotive spatially is divided between driver's cab and machinery by partition wall, and the main control member of arranging locomotive air braking system and electrical system in the driver's cab is driver and conductor's routine work zone; The main power unit of arranging locomotive between machinery, as: the equipment such as current transformer, high pressure cabinet, ventilator, air compressor.Control member is connected with power unit and is connected with cable by pipeline, and these pipeline and cables that connect usefulness need to enter driver's cab by passing partition wall between machinery.
Development along with the electric locomotive manufacturing technology, the driver and conductor is more and more higher to the requirement of comfortable working environment degree, in order effectively to improve the sealing of driver's cab, noise is on the impact of driver's cab between reduction machinery, reduce the convection effect between driver's cab and machinery, need to carry out encapsulation process to cable and the pipeline that passes partition wall.
At present, in the electric locomotive manufacture process, the method that the sealing means of the cable of wearing partition wall, pipeline is generally adopted: at first perforate on partition wall, after passing cable and pipeline, use sealer or stabilizer to fill sealing.
There is following shortcoming in prior art:
1) maintainable poor
Electric locomotive regular maintenance, in repair or during overhaul, need to change cable or pipeline.Adopt existing sealing means when more pipeline cable or pipeline, at first need packing is cleaned out, then change cable or pipeline, changes and completely refilling sealer or stabilizer afterwards.Renewal process is loaded down with trivial details, and packing cleaning difficulty is maintainable poor.
2) sealing is poor
Because cable is into wire harness and passes partition wall, so sealer or stabilizer can not effectively be filled the slight gap between cable, cause poorly sealedly, sealing is relatively poor.
3) poor stability
Because sealer, stabilizer all belong to inflammable or combustible product, even add fire retardant, its flame retardant property is relatively poor, uses in electric locomotive to have certain potential safety hazard.
The model utility content
The technical problem that the utility model solves is to overcome the deficiencies in the prior art, provides a kind of easy to loading and unloading, and good sealing effect uses safe combined seal structure.
The technical solution adopted in the utility model is that mounting plate is fixed on the partition panel by construction bolt, fixing steel pipe on the mounting plate, and cable or pipeline pass steel pipe, are full of rubber body in the steel pipe, and the rubber body two ends are provided with clamping plate, and clamping bolt makes clamping plate clamp rubber body.
At first on driver's cab and mechanical separation wallboard, open thread hole according to the corresponding size of mounting plate, mounting plate adopts construction bolt to be installed on the partition panel, cable or the pipeline of encapsulation process will be needed, pass the steel pipe on the mounting plate, reinstall rubber body (can split), by the clamping bolt on the fit sealing rubber body, drive the clamping plate of rubber body, the compressing rubber body under the acting in conjunction of clamping plate, rubber body, steel pipe, reaches the sealing to cable or pipeline.
Be provided with sealing joint strip between mounting plate four limits and the partition panel, seal.
Rubber body is ethylene propylene diene rubber.Ethylene propylene diene rubber has good heat resistance, lower temperature resistance and electrical insulating property, and its oxygen index 〉=29% belongs to nonflammable material, can reduce disaster hidden-trouble.
Clamping plate are the semicircle annular slab.Semicircle annular slab easy accessibility.
The beneficial effects of the utility model are:
1) modularity, applicability are strong: can select different seals to make up according to cable or the pipeline of different-diameter, and applied widely.
2) good seal performance: cable or pipeline are adopted single, the one by one sealing of seal, can effectively solve the existing poorly sealed problem of sealing means.
3) easy to maintenance, simple to operate: when changing cable or pipeline, only need seal is pulled down, changed cable or pipeline after, former seal loaded onto again get final product.
4) good economy performance: seal can reuse, and can effectively reduce the maintenance cost of locomotive.
5) safe: the rubber body of seal and sealing joint strip adopt ethylene propylene diene rubber (EPDM), have good heat resistance, lower temperature resistance and electrical insulating property, and its oxygen index 〉=29% belongs to nonflammable material, can reduce disaster hidden-trouble.
Description of drawings

Be labeled as among the figure: 1-mounting plate, 2-partition panel, 3-steel pipe, 4-rubber body, 5-cable or pipeline, 6-clamping plate, 7-clamping bolt, 8-construction bolt, 9-sealing joint strip.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Be illustrated in figure 1 as the structural representation of combined seal structure of the present utility model.Combined seal structure, mounting plate 1 is fixed on the partition panel 2 by construction bolt 8, fixing steel pipe 3 on the mounting plate 1, cable or pipeline 5 pass steel pipe 3, be full of rubber body 4 in the steel pipe 3, rubber body 4 two ends are provided with clamping plate 6, and clamping bolt 7 makes clamping plate 6 clamp rubber body 4.
At first on driver's cab and mechanical separation wallboard, 2 open thread hole according to the corresponding size of mounting plate 1, mounting plate 1 adopts construction bolt 8 to be installed on the partition panel 2, cable or the pipeline 5 of encapsulation process will be needed, pass the steel pipe 3 on the mounting plate 1, reinstalling rubber body 4(can split), by the clamping bolt 7 on the fastening rubber body 4, drive the clamping plate 6 of rubber body 4, compressing rubber body 4 under the acting in conjunction of clamping plate 6, rubber body 4, steel pipe 2, reaches the sealing to cable or pipeline 5.
