Abstract

The invention relates to a tool for stripping the insulating layer of a control cable, which comprises a knife shell, a cutter bar and a pressing device, wherein the knife bar protrudes through the knife shell, and a knife head is provided at the inner end of the knife bar; the pressing device includes a sleeve The spring, connecting rod and pressing pulley arranged on the knife rod, one end of the connecting rod stretches into the knife shell and is connected with the spring, and the other end is installed at the position corresponding to the position of the knife head, and the pressing pulley is installed; the other end of the spring is connected with the knife The shell is fixed. The invention has simple structure and convenient operation, can safely and quickly strip the insulation layer of the control cable without damaging the insulation of the inner core, and reduces the safety hazards of the power grid operation.

Description

The control cables tool for stripping insulating layer

Technical field

The present invention relates to a kind of exfoliation tool, especially for the specific purpose tool of peeling off the control cables insulating barrier.

Background technology

In the relaying protection work progress, the insulating barrier at the outside two ends of a large amount of control cables need to be divested.Owing to there is not suitable control cables insulation displacement specific purpose tool, general multiplex paper knife divests insulating barrier at present.Yet, because paper knife is very sharp, is easy to hurt the insulation of control cables internal core during exploitation, thereby makes easily the safe operation of relaying protection have accident potential on the one hand; Control cables is column type on the other hand, and the surface has rough and uneven in surface (there is the steel armour inside), and paper knife easily skids when wire stripping, and staff's hand channel is often hurt when operation, has brought very large trouble to construction.

Summary of the invention

The object of the invention is to overcome the prior art deficiency, a kind of simple in structure, easy to operate control cables tool for stripping insulating layer is provided, thereby realize divesting safely and fast the control cables insulating barrier.

For achieving the above object, the present invention adopts following technical scheme:

A kind of control cables tool for stripping insulating layer comprises cutter shell, knife bar and hold down gag, and wherein knife bar passes the cutter shell and stretches out, and knife bar the inner is provided with cutter head; Described hold down gag comprises spring, connecting rod and the compression pulley that is set on the knife bar, and described connecting rod one end stretches in the cutter shell and is connected with spring, and the other end and corresponding section, cutter head position are installed and compressed pulley; The described spring other end and cutter shell are fixed.

Described knife bar one end has screw thread, and inboard, cutter shell relevant position is provided with the screw thread that matches; Described knife bar outer end is provided with adjusting knob.

An end opposite with knife bar on the described connecting rod is provided with handle.

Described cutter head can have any shape, and wherein is preferably V-arrangement.

Good effect of the present invention: adopt interior blade, can not hurt staff's hand; Utilize hold down gag that control cables is stuck in cutter head and compress between the pulley, to spur simultaneously handle and shell the be strip off insulating barrier of control cables.The present invention is simple in structure, and easy-to-operate can be peeled off the insulating barrier of control cables outside easily, rapidly and can not hurt the insulation of internal core, has improved the reliability of operation of power networks, has reduced the potential safety hazard of operation of power networks.

Embodiment

Below in conjunction with accompanying drawing the present invention is described in further details, but protection scope of the present invention is not limited to this.

As shown in Figure 1, a kind of control cables tool for stripping insulating layer comprises cutter shell 4, knife bar 2 and hold down gag, and wherein knife bar 2 passes cutter shell 4 and stretches out, and knife bar 2 the inners are provided with cutter head 5; Described hold down gag comprises spring 3, the connecting rod 6 that is set on the knife bar 2 and compresses pulley 7 that described connecting rod 6 one ends stretch in the cutter shell 4 and are connected with spring 3, the other end and corresponding section, cutter head 5 position installation compression pulley 7; Described spring 3 other ends and cutter shell 4 are fixing.Described knife bar 2 one ends have screw thread, and inboard, cutter shell 4 relevant position is provided with the screw thread that matches; Described knife bar 2 outer ends are provided with adjusting knob 1.An end opposite with knife bar 2 on the described connecting rod 6 is provided with handle 8.Described cutter head 5 is shaped as V-arrangement.Cutter head 5 is replaceable.

Control cables insulation displacement process is as follows: observe first the thickness of control cables 9 external insulations, rotate adjusting knob 1, cutter head 5 is adjusted to appropriate length; Pulling handle 8 utilizes the elastic force of hold down gag medi-spring 3 control cables 9 to be stuck in cutter head 5 and to compress between the pulley 7 cutter head 5 automatic incision insulating barriers; The right-hand man holds cutter shell 4 and handle 8 and begins to slide, in its slip, i.e. strip off the insulating barrier of control cables 9.

The present invention adopts interior blade, can not hurt staff's hand, and simple in structure, and easy-to-operate can be peeled off the insulating barrier of control cables outside easily, rapidly and can not hurt the insulation of internal core, has reduced the potential safety hazard of operation of power networks.
