Description
Technical field
The present invention relates to a kind of cable bearer of subway tunnel inner support cable, belong to the mechanized equipment technical field.
Background technology
The tunnel normal operation shield methods such as subway are built and are formed, the side is circular arc or the shape of a hoof, cable bearer in traditional tunnel all adopts the metal-plated Zinc material to make, the manufacturing process energy consumption is large, operation is many, the cycle is long, cost is high, and product quality can't guarantee, and fully naked protection, under many severe environmental conditions, occasions such as subway, tunnel, chemical enterprise, rainy humidity or coastal salt fog, use very easily corrosion of conventional stent, the maintenance cost of facility is high, and application life is also shorter.Aspect antirust, anti-corrosive, though adopt at present the technical finesses such as outer painting or galvanizing, but still can not fundamentally solve the corrosion problem, have a strong impact on safety and the trouble-free life of electric power, communications facility.
Also there is minority to adopt glass fiber reinforced plastic to make cable bearer, but all be that whole die sinking mold pressing forms, and the tunnel, the installation requirement of cable bearer is the necessary level of support arm, when the tunnel inner wall circular arc presents when irregular, when perhaps the height error appearred in the installation of bracket base, the support arm of integrated support can be at an angle with level, and can't be adjusted to level, therefore again whole die sinking, the monolithic cable support of multiple angles is provided, and the die sinking cost is higher, and installs inconvenient.
Summary of the invention
The technical problem that actual needs of the present invention solves is: in the subway tunnel, the support arm of the monolithic cable support of glass steel material is in case at an angle with level, can't be adjusted to level, just can't use, can only be to cable bearer again whole die sinking, the monolithic cable support of multiple support arm angle is provided, and the die sinking cost is higher, and installs inconvenient.
The present invention takes following technical scheme:
A kind of cable bearer of subway tunnel inner support cable, described cable bearer is glass steel material, it is characterized in that: comprise support arm 1, inserted block 2, base 3, described base 3 elongated structures, side near tunnel wall is inboard, and opposite side is the outside, which is provided with the groove 3a of at least one lateral direction penetrating, the inboard notch of described groove 3a is greater than outside notch, the profile of described inserted block 2 and described groove 3a corresponding matching; Described inserted block 2 has groove, and side connects before and after the described groove, and inner groove surface 2b area is greater than the notch area of groove, described support arm 1 afterbody and described groove fit; The afterbody of described support arm 1 inserts described groove, and described inserted block 2 inserts described groove 3a.
Further, the upper and lower end of described base 3 is provided with installing hole 4, and described cable bearer is fixed on the shield structure wall of described subway tunnel by described installing hole 4.Further, described support arm 1 level.
Support arm, inserted block, base have formed knockdown cable bearer by providing independently in the present invention, and this cable bearer is fixed the combination of support arm, inserted block, base cleverly, and the cable bearer of again combination being finished is fixed on the tunneling shield wall.When manufacturing and designing this cable bearer, provide the inserted block of multiple angles groove, thus just can be so that support arm form different angles from base by changing inserted block, and the volume of inserted block is little, the cost of die sinking, cast is lower, and easy to assembly.
Beneficial effect of the present invention is:
1, installation, easy to adjust, freely select inserted block to arrange in pairs or groups;
2, for the different angle of support arm, the inserted block of different angles groove only need be provided, need not the whole die sinking of cable bearer is greatly reduced the die sinking cost;
3, especially be fit to the interior cable bearer of subway tunnel, have widely marketing prospect, have great commercial value.

The specific embodiment
The present invention is further described below in conjunction with specific embodiment.
Shown in Fig. 4-9, cable bearer of the present invention is glass steel material, is fixed on the inner shield structure of the subway tunnel wall, as fixing and the guiding cable is used.This cable bearer comprises separately independently support arm 1, inserted block 2, base 3.In conjunction with such as Fig. 4, Fig. 6, can find out that inserted block 2 is the cuboid shape, contain flutedly, connect before and after this groove, Eight characters opening is inside; Shown in Fig. 5-7, in the groove of support arm 1 on fore-and-aft direction insertion inserted block 2, match with groove, because groove Eight characters outward opening Gu support arm 1 is fixed in the inserted block 2, can not relatively move with inserted block 2 horizontal cross; Shown in Fig. 8-9, base 3 is for having the strip structure of cambered surface, this cambered surface is corresponding with the radian of subway tunnel shield wall, one side of fitting with the tunneling shield wall is for being defined as the inboard, a side that links to each other with support arm 1 is defined as the outside, base 3 is provided with four groove 3a, groove 3a's is upper, lower groove face is Eight characters opening shape to the inside, the profile of inserted block 2 is fully corresponding with groove 3a, inserted block 2 and rear the insertion in the groove 3a of support arm 1 combination because groove 3a is the inside shape of Eight characters opening, can't be pulled out so inserted block 2 inserts the backward outside of groove 3a, so far, each component assembling of cable bearer of the present invention is finished.As shown in Figure 4, the two ends of base 3 are provided with installing hole 4, and by this installing hole, the cable bearer that assembling is finished is fixed on the subway tunnel shield wall, finishes installation.
In actual use, because the subway tunnel shield wall is irregular, it is out-of-level that cable bearer is waited unavoidable generation support arm when mounted, or do not reach suitable perk angle, therefore need to prepare the inserted block 2 that multiple interior grooves is different angles, at this moment, only need to change the inserted block 2 of other angles of preprepared, support arm 1 is adjusted to suitable perk angle, finish the installation of cable bearer.
Cable bearer simple installation of the present invention, inserted block die sinking cost has the prospect of marketing, great commercial value far below the die sinking of Integral cable support.
