Description
Technical Field
The invention relates to tunnel cable installation equipment, in particular to a tunnel cable hanger.
Background
The existing method for erecting cables in the tunnel generally installs cable brackets on the tunnel wall by using anchor bolts, and then installs the cables on the cable brackets. The common cable bracket is characterized in that a part for clamping the cable is an upper semicircular independent part and a lower semicircular independent part, the lower semicircle is fixed on the bracket, the cable is rotated on the lower semicircle and then covered by the upper semicircle, and finally, two ends of the upper semicircle and the lower semicircle are fixed by bolts, so that the installation process is complicated. Except this problem, because be smooth structure between apron and the supporting seat inboard, the cable is easy to the drunkenness, can not reach good fixed effect after the installation cable. In addition, the ground wire is inconvenient to install.
For solving these problems, the chinese utility model patent with the publication number of CN208073559U discloses a novel tunnel cable hanger, including erecting fixed plate, semi-circular supporting seat, activity clamp, ground connection metal sheet, ground connection checkpost, ground connection mechanism, activity clamp one end itself with erect the fixed plate be connected, only need with the other end with semi-circular supporting seat be connected can, in addition, the problem of having installed the ground wire inconvenient installation is solved to the ground structure who contains the ground connection checkpost. But this technical scheme does not solve the loaded down with trivial details problem of installation of activity clamp and semi-circular supporting seat completely. Because the cable is heavier, place back on semi-circular supporting seat, still need hold the cable with the hand when the installation activity is pressed from both sides, prevent that the cable between two stores pylon is flagging, still will press from both sides the activity simultaneously and semi-circular for the supporting seat bolted connection, hardly accomplish alone.

In one embodiment, the free end of the movable clamp and the corresponding part of the supporting seat are provided with matched bolt holes for fixing the free end of the movable clamp and the supporting seat by mounting bolts.
In one embodiment, the bottom of the screw is provided with a handle.
In one embodiment, the semicircular inner side of the movable clamp is also provided with a non-slip pad.
In one embodiment, the bottom of the L-shaped card is provided with a bend.
The invention has the advantages and beneficial effects that: when the cable fixing device is used, a cable is firstly placed in a semicircle of the supporting seat, the cable tightly presses the arc-shaped part of the conductive needle, the movable clamp is buckled on the cable, the lower part of the L-shaped clamping piece on the movable clamp is propped open by the bulge on the supporting seat, the bulge is embedded into the through groove when the movable clamp is pressed downwards, the movable clamp is locked and cannot be automatically opened upwards, an operator presses the cable tightly to enable the bulge to be embedded into the proper through groove, and then the cable is installed, and the installation can be completed by a single person. If the cable can be further reinforced by installing bolts in bolt holes on the movable clamp and the supporting seat, the installation of the cable can be more fastened by rotating a screw in a threaded hole at the bottom of the supporting seat to extrude the anti-slip pad. The conductive needle with the wavy arc shape is in multipoint contact with the cable, so that the reliability of electrical connection is higher.
