Abstract

The utility model relates to a fixture suitable for large cross-section cables. The fixture comprises an upper fixture body and a lower fixture body; screw holes are formed in corresponding positions on the two sides of the upper fixture body and in corresponding positions on the two sides of the lower fixture body; and the upper fixture body is fixedly connected with the lower fixture body via a connecting bolt. Compared with the prior art, the fixture has a high space utilization rate in a cross section of a tunnel, can be suitable for occasions, such as long path sections, industrial well sections, climbing sections, cable joint sections, entrance-exit sections, and the like to perform the functions of supporting and protecting the cables according to the cable laying requirements in different use occasions, is suitable for being applied to the large cross-section cables which have large clamping cross sections, high current carrying capacity and heavy weight, and have low probability of bending, and is instructive to the use of the fixture in cable engineering.

Description

The anchor clamps that a kind of suitable electric cable with large cross-section uses
Technical field
The utility model relates to a kind of cable clamping device, especially relates to the anchor clamps that a kind of suitable electric cable with large cross-section uses.
Background technology
Along with the continuous expansion and the renewal of electrical network, in order to adapt to the needs of power system development, the electric pressure of city net transmission line constantly improves, and the cross section of cable also constantly increases.Because the tunnel does not occupy ground space, and can build in advance, get ready for later cable laying construction, solved the repeatedly problem on the broken road of construction, help the improvement of the appearance of the city and environment, the design of power cable tunnel and application increase day by day.
Because the requirement of high voltage, heavy in section cable transmission capacity, heat radiation around the cable is had relatively high expectations, system of layings such as original Shanghai comb commonly used, direct-burried, cable trough have been not suitable for the needs of this type of cable, and therefore building the electric power dedicated tunnel becomes the main mode that high voltage, electric cable with large cross-section lay.
Aspect the use of cable cleat, during laying, prior cable mostly adopts band, plastic clamp, traditional fixture rail or common aluminum alloy anchor clamps, can not effectively retrain cable, cable is axially adopted vertically all solutions well of electric power influence between living slippage and cable; And the intensity of these materials and decay resistance are all poor, are not suitable for using in the more abominable tunnel of environment.
Abroad, there is the design and running experience of comparative maturity in states such as Japan, European Union for the cable laying in general tunnel, but relate to the system and the perfect method without comparison of laying also of high voltage, electric cable with large cross-section.
Summary of the invention
The purpose of this utility model is exactly the anchor clamps that provide a kind of space availability ratio height, suitable electric cable with large cross-section applied widely to use for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
The anchor clamps that a kind of suitable electric cable with large cross-section uses are used for card and establish attached cable, it is characterized in that these anchor clamps comprise upper clamp and lower clamp, and the correspondence position of the both sides of described upper clamp and lower clamp offers screw, and upper clamp and lower clamp are affixed through connecting bolt.
Described upper clamp is arch-shaped structure, and arc groove is offered at the middle part.
Described lower clamp and upper clamp are mirror image, and arc groove is offered at the middle part of this lower clamp.
The bottom of described lower clamp is provided with the connection platform.
In the described groove screw thread can also be set.
Compared with prior art; the space availability ratio height of the utility model in tunnel cross-section; can be according to the requirement of cable laying in the different use occasions; be applicable to that occasions such as long highway section, worker's well section, climbing section, cable joint section, gateway section play the effect of supporting cable and protection cable; it is big to be fit to be applied to the clamping cross section, and ampacity is big, and weight is big; unbending electric cable with large cross-section has directive significance to the use of anchor clamps in the cable work.
Description of drawings
Fig. 1 is a structural representation of the present utility model among the embodiment 1.
1 is that upper clamp, 2 is that lower clamp, 3 is connecting bolt among the figure.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment 1
The anchor clamps that a kind of suitable electric cable with large cross-section uses, be used for card and establish fixedly electric cable with large cross-section, its structure as shown in Figure 1, these anchor clamps comprise upper clamp 1 and lower clamp 2, upper clamp 1 is arch-shaped structure, arc groove is offered at the middle part, in this groove screw thread can also be set, and lower clamp 2 is a mirror image with upper clamp 1, the middle part also offers arc groove, the bottom of lower clamp 2 also is provided with the connection platform, connects the screw of platform through two ends, thus fixing whole anchor clamps.The correspondence position of the both sides of upper clamp 1 and lower clamp 2 offers screw, and upper clamp 1 and lower clamp 2 are affixed through connecting bolt 3.
During use, earlier attachment screw 3 is taken off, electric cable with large cross-section is placed in the recess space of upper clamp 1 and the formation of lower clamp 2 middle parts, screw attachment screw 3 then, promptly finish fixing electric cable with large cross-section.
Embodiment 2
The anchor clamps that a kind of suitable electric cable with large cross-section uses are used for card and establish fixedly electric cable with large cross-section, and the groove of the lower clamp of these anchor clamps is two sections arcuate structures, and all the other structures are identical with embodiment 1, can conveniently clamp electric cable with large cross-section by these anchor clamps.
