Abstract
The utility model discloses a kind of fire-resistant cable slot boxes, are related to cable tray technical field.The fire-resistant cable slot box includes slot box body, the components such as spacer bar and retention bead, the surface of slot box body is coated with fire-resistant rubber layer, the chemical component and parts by weight meter of fire-resistant rubber layer are as follows: base rubber: 100 parts, magnesium silicate: 8-12 parts, mica powder: 4-14 parts, aluminum phosphate: 3-6 parts, calcium carbonate: 3-11 parts, thermally expandable graphite: 15-40 parts, adhesive: 10-30 parts, inorganic filler: 30-90 parts, 1-10 parts of vulcanizing agent, the excessively adjacent spacer bar of pain is to the just ordered categorization of all cables, so that staff is convenient for resolution and maintenance, when fire occurs, thermally expandable graphite is expanded into 100 times or more, thermal insulation layer is formed on the surface of slot box body, to effectively prevent the temperature of slot box body from rising, flame is also effectively prevented simultaneously Inflow so that fire-resistant cable slot box meets the performance requirement of fire resistance.
Description
Technical field
The present invention relates to cable tray technical fields, more particularly to a kind of fire-resistant cable slot box.
Background technique
With the fast development of national economy and society, energy demand is increasing nervous with human resources, the completion time of project
Tightly, electricity power engineering quality and technique require more and more high contradiction more and more prominent, and the existing construction mode of substation can not
Adapt to new requirement.Accelerate construction of transformer substation progress, improve construction quality, substation's construction should using modularization, standardization,
The factorial production, scene only carry out simple assembly model.
Concrete cable trench complicated construction technique, maintenance period are long, larger by the external environments influence factor such as weather, seriously
The construction period of engineering constraint, the cable tray made of steel or composite material complete product design and life in factory
Processing is produced, simply assemble to substation field, the completion time of project is greatly shortened, improves working efficiency, reduces construction
With operation cost, preserve the ecological environment.
Currently, the Chinese patent of Publication No. CN205407163U discloses a kind of cable tray of lateral openings, the electricity
The notch of cable slot box is set to the either side in square groove box body surrounding in addition to top and bottom, that is, uses lateral openings,
Each layer outlet in this way inside cable tray is against notch.So each layer can synchronize progress and not do mutually when being laid with cable
It disturbs, solves the problems, such as that existing open-topped cable tray multilayer while can not be routed, and the nothing in subsequent Inspection and maintenance
Upper layer cable need to be opened to check lower layer's cable.
Although the cable tray of the lateral openings is provided with cable limiting slot, but since the height of cable limiting slot has
Limit, when cable tray domestic demand places multi-cable, cable can only be partially placed in cable limiting slot, and remaining cable
It is then put by unordered, is unfavorable for staff and overhauls.
Summary of the invention
When the technical problem to be solved by the present invention is to place cable, not every cable can orderly be put,
It is unfavorable for staff to overhaul.
In order to solve the above technical problems, the present invention provides a kind of fire-resistant cable slot box, including slot box body and cover board, slot
Box body is set as opening up U-lag box, and the interior both ends along length direction of slot box body are equipped with limiting device, limit
Device includes several spacer bars along the setting of slot box body width direction, and the upper end of spacer bar is equipped with for limiting cable from limit
To the retention bead of outer displacement in device.
The technical solution that the present invention further limits is: spacer bar is equidistantly spaced along the width direction of slot box body and sets
It sets.
Further, the height of spacer bar is set as identical as the height of slot box body.
The preceding fire-resistant cable slot box, retention bead are resiliently attached to the upper of spacer bar along slot box body width direction
End.
The preceding fire-resistant cable slot box, retention bead are respectively arranged on spacer bar along the two sides of slot box body width direction.
The beneficial effects of the present invention are:
In the present invention；Cable is placed by the space between adjacent two spacer bar, cable is being placed in slot box
When in ontology, different types of cable is placed between the spacer bar at different location according to classification, and be placed in slot simultaneously
The corresponding position at box body both ends, so that it is more firm when cable is placed, simultaneously because the elastic connection of retention bead, makes
Cable only needs manually to exert a force and can enter between spacer bar when placing, while cable be also not easy to be displaced to two spacer bars it
Outside.Since the height of spacer bar is identical as slot box body, so a plurality of cable can be prevented between adjacent two spacer bar, thus just
Classify and identify in staff, and then is conducive to the maintenance of staff.
Detailed description of the invention
Fig. 1 is the connection schematic diagram of slot box body and cover board of the present invention；
Fig. 2 is the structural schematic diagram of limiting device of the present invention；
Fig. 3 is the enlarged diagram in Fig. 2 at A.
Wherein: 1, slot box body；2, cover board；3, limiting device；31, spacer bar；32, retention bead.
Specific embodiment
A kind of fire-resistant cable slot box provided in this embodiment, structure is as shown in Figure 1 to Figure 2, including slot box body 1 and cover board
2, slot box body 1 is set as opening up U-lag box, is equipped with limit along the both ends in length direction in slot box body 1 and fills
3 are set, limiting device 3 includes several spacer bars 31 along the setting of 1 width direction of slot box body, and spacer bar 31 is along slot box body 1
Width direction is equidistantly spaced setting, and the height of spacer bar 31 is set as identical as the height of slot box body 1；Spacer bar 31
Upper end is equipped with for limiting cable out of limiting device 3 to the retention bead of outer displacement 32, and retention bead 32 is wide along slot box body 1
Degree direction is resiliently attached to the upper end of spacer bar 31, and retention bead 32 is respectively arranged on spacer bar 31 along 1 width side of slot box body
To two sides.
It when cable to be placed in slot box body 1, is grouped first according to the classification difference of cable, then by same group
Cable be sequentially placed between identical adjacent two spacer bar 31 from the bottom to top, while it is corresponding to guarantee that cable is also placed on
Between adjacent two spacer bar 31 of the other end, so that it is more firm when cable is placed, simultaneously because the elasticity of retention bead 32
Connection, so that cable only needs manually to exert a force when placing can enter between spacer bar 31, while cable is also not easily disconnected from
Except two spacer bars 31.Since the height of spacer bar 31 is identical as slot box body 1, so can be to prevent between adjacent two spacer bar 31
Only a plurality of cable, consequently facilitating staff's classification and identification, and then it is conducive to the maintenance of staff.
In addition to the implementation, the present invention can also have other embodiments.It is all to use equivalent substitution or equivalent transformation shape
At technical solution, fall within the scope of protection required by the present invention.
