Description

Tunnel cable separation hook

Technical Field

The utility model belongs to the technical field of tunnel construction, a couple is separated to tunnel cable is specifically disclosed.

Background

The wiring in the tunnel is generally long in transmission distance, and in order to facilitate the condition that the cable is connected with a load in the middle, a phase line, a grounding line and a neutral line cable are required to be arranged in a separated and synchronous mode frequently. The general laying method is that a vertical pole is arranged on the wall of the tunnel, a porcelain insulator is arranged along the vertical direction, and a cable is fixed on the porcelain insulator through an insulating material. The wiring needs a lot of materials, the installation and the disassembly are complicated, and if the vertical pole and the porcelain insulator are installed on the wall of the tunnel at a certain angle, the cable is easy to fall off from the porcelain insulator under the action of the self gravity.

SUMMERY OF THE UTILITY MODEL

The utility model provides a couple is separated to tunnel cable to it is many, the cable installation dismantles miscellaneous to improve the required material of current wiring mode, the technical problem that the cable easily drops when the tunnel wall mounting cable of certain angle.

In order to achieve the above object, the present invention provides a tunnel cable partition hook, which comprises a fixing member for fixing on a tunnel wall, a bearing member located below the fixing member, and a connecting and rotating member rotatably connecting the fixing member and the bearing member; a plurality of hooks are vertically arranged on the bearing part.

Furthermore, the fixing piece is provided with a through hole and fixed on the tunnel wall through a screw.

Further, the number of the through holes is at least two.

Further, the connecting rotating piece is a bolt provided with a nut; the bottom end of the fixed part is provided with a fixed sleeve; the top end of the bearing part is provided with a rotating sleeve; the bolt passes through the fixed sleeve and the rotating sleeve, and the screw rod in the fixed sleeve and the rotating sleeve is a smooth rod.

Further, the central angle of the hook is larger than 180 degrees.

Further, the hook is made of an insulating material or is covered with an insulating layer.

The utility model has the advantages of it is following:

by adopting the tunnel cable separation hook, even if the cable is installed on the tunnel wall with a certain angle, the bearing part and the hook on the bearing part can still rotate under the self gravity to be consistent with the gravity direction, and the cable is not easy to fall off after being installed; the central angle of the hook is larger than 180 degrees, namely the opening is smaller, the cable is not easy to fall off, the inner diameter and the opening size can be processed according to the cable requirement of the tunnel construction power scheme, and the hook can be applied to the erection of cables with different specifications; the hook is made of an insulating material or is covered with an insulating layer, has insulating property and meets the insulating requirement; after the cable is installed, due to the gravity of the cable and the small size of the opening of the hook, human factors are eliminated, and the cable is not easy to fall off; the hook for separating the tunnel cables is simple in design, easy to machine in mass production, convenient to install and detach the cables and great in application and popularization significance.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment provides a tunnel cable partition hook, which comprises a fixed part 1 fixed on the tunnel wall, a bearing part 2 positioned below the fixed part 1, and a connecting rotating part 3 rotatably connecting the fixed part 1 and the bearing part 2; the vertical a plurality of couples 4 that are provided with on the bearing part 2, bearing part 2 can be because self gravity and bear the weight of cable and hang down freely. The number of the hooks 4 can be determined according to the number of the cables.

Further, the fixing piece 1 is provided with a through hole 5, and the fixing piece is fixed on the tunnel wall through a screw 6, so that the fixing of the tunnel cable separation hook is realized.

Further, the number of the through holes 5 is at least two, and in the case where one of the through holes 5 is damaged, the other through holes 5 may be used.

Further, the connecting rotating member 3 is a bolt provided with a nut; the bottom end of the fixing piece 1 is provided with a fixing sleeve; the top end of the bearing part 2 is provided with a rotating sleeve; the bolt passes through the fixed sleeve and the rotating sleeve to realize the rotating connection of the fixed part 1 and the bearing part 2, and the screw rod in the fixed sleeve and the rotating sleeve is a smooth rod.

Further, the central angle of the hook 4 is larger than 180 degrees, namely the opening of the hook 4 is small, and the cable is not easy to fall off.

Further, the hook 4 is made of an insulating material or the hook 4 is covered with an insulating layer, so that the hook has insulating property and meets the insulating requirement. Preferably, the hook 4 is made of a flexible compact plastic piece, having both insulating properties and elasticity, so as to firmly clamp the cable inside the hook 4.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
