Description
Technical field
The present invention relates to a kind of cable bearer of subway tunnel inner support cable, belong to mechanized equipment technical field.
Background technology
The tunnels such as subway generally use shield method to build and form, side is circular arc or the shape of a hoof, cable bearer in traditional tunnel all adopts metal-plated Zinc material to make, manufacturing process energy consumption is large, operation is many, the cycle is long, cost is high, and product quality cannot ensure, and naked protection completely, under many severe environmental conditions, the occasions such as such as subway, tunnel, chemical enterprise, rainy humidity or coastal salt fog, use conventional stent very easily corrosion, the maintenance cost of facility is high, and application life is also shorter.In antirust, anti-corrosive, though at present adopt the technical finesse such as outer painting or galvanizing, but still fundamentally can not solve corrosion problem, have a strong impact on electric power, the safety of communications facility and trouble-free life.
Also minority is had to adopt glass fiber reinforced plastic to make cable bearer, but be all that overall die sinking mold pressing forms, and tunnel, the installation requirement of cable bearer is the necessary level of support arm, when tunnel inner wall circular arc presents irregular, or when height error appears in the installation of bracket base, the support arm of integrated support can be at an angle with level, and cannot be adjusted to level, therefore can only overall die sinking again, there is provided the monolithic cable bearer of multiple angles, 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 subway tunnel, the support arm of the monolithic cable bearer of glass steel material is once at an angle with level, level cannot be adjusted to, just cannot use, can only to cable bearer again overall die sinking, there is provided the monolithic cable bearer of multiple support arm angle, 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, the elongated structure of described base 3, the side of close tunnel wall is inner side, and opposite side is outside, which is provided with the groove 3a of at least one lateral direction penetrating, the inner side 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 before and after described groove, side is through, 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.
The present invention defines knockdown cable bearer by providing independently support arm, inserted block, base, and the combination of support arm, inserted block, base is fixed by this cable bearer cleverly, then is fixed on tunneling shield wall by the cable bearer combined.When manufacturing and designing this cable bearer, provide the inserted block of multiple angles groove, thus support arm and base just can be made to form different angles 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, install, easy to adjust, unrestricted choice inserted block arranges in pairs or groups;
2, for the different angle of support arm, only need provide the inserted block of different angles groove, without the need to the overall die sinking of cable bearer, greatly reduce die sinking cost;
3, be especially applicable to the cable bearer in subway tunnel, there is marketing prospect widely, there is great commercial value.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further described.
As shown in figures 4-9, cable bearer of the present invention is glass steel material, is fixed on subway tunnel inner shield structure wall, as fixing and 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 for cuboid shape, containing fluted, through before and after this groove, Eight characters opening is inside, as illustrated in figs. 5-7, support arm 1 inserts from fore-and-aft direction in the groove on inserted block 2, and with fit depressions, due to groove Eight characters outward opening, clamped brace 1 is fixed in inserted block 2, can not relative movement with inserted block 2 horizontal cross, as Figure 8-9, base 3 is for having the string configuration of cambered surface, this cambered surface is corresponding with the radian of subway tunnel shield wall, one side of fitting with tunneling shield wall is for being defined as inner side, the side be connected with support arm 1 is defined as 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 completely corresponding with groove 3a, inserted block 2 and support arm 1 combine in rear insertion groove 3a, because groove 3a is the inside shape of Eight characters opening, so inserted block 2 cannot pull out to outside after inserting groove 3a, so far, the each component assembling of cable bearer of the present invention completes.As shown in Figure 4, the two ends of base 3 are provided with installing hole 4, by this installing hole, are fixed on subway tunnel shield wall by the cable bearer assembled, complete installation.
In actual use, because subway tunnel shield wall is irregular, it is out-of-level that unavoidable generation support arm waited when mounted by cable bearer, or do not reach suitable tilting angle, therefore need to prepare the inserted block 2 that multiple interior grooves is different angles, now, only need change the inserted block 2 of other angles of preprepared, support arm 1 is adjusted to suitable tilting angle, completes the installation of cable bearer.
Cable bearer simple installation of the present invention, inserted block die sinking cost, far below the die sinking of Integral cable support, has the prospect of marketing, great commercial value.
