Abstract

The utility model provides an R-type grounding wire clamp, which comprises an insulating rod. An elastic sheet is fixed to the top end of the insulating rod, and the elastic sheet and the insulating rod together form an R-shaped structure. The other end of the elastic sheet is fixedly provided with a pull rod and the other end of the pull rod is fixedly provided with a pull rope. A supporting rod is fixed on the pull rod. According to the technical scheme of the utility model, the R-type grounding wire clamp is simple in structure and convenient to use. During operation, the R-type grounding wire clamp is time-saving, labor-saving and high in working efficiency. By means of the R-type grounding wire clamp, a grounding wire can be hung on to various poles and towers by one shot, and the safety performance is high. Meanwhile, the personal safety of operators is ensured. The R-type grounding wire clamp is light in self-weight, convenient to carry about, labor-saving to remove, and more safer in operation. Moreover, the R-type grounding wire clamp has no damage to power transmission wires.

Description

R type earthing wire clip

Technical field

The utility model relates to a kind of grounding wire device using for transmission line power failure operation, the R type earthing wire clip particularly using on a kind of terminal shaft tower.

Background technology

Personal safety for protection operating personnel in transmission line power failure operation must be installed earth connection in advance.For a long time in the time articulating wide-angle corner and terminal shaft tower earth connection, many in upside-down mounting wire clamp outside owing to articulating position, distant and be lateral separation, therefore in practical operation, often need to throw and hang up hundred ability successfully, consuming timely exceed two hours, waste time and energy.The patent No. is that CN200620022638.6 discloses a kind of earth lead clamp device of circuit shorting of transmitting electricity, and this device is to be made up of wire clamp, inner spring bolt, shell fragment, intermediate plate, balancing weight, annealed copper wire, insulation operating joint.The problem that this device exists is: while 1, articulating on straight line pole, use insulating cord to connect the weight of insulation operating connector by using wire clamp own and in dropping process, clash into and block wire, because operating personnel present position is higher, be subject to windage larger, therefore be difficult to once articulate successfully, operating process is wasted time and energy, inefficiency, as running into strong wind atmosphere, to articulate difficulty larger; 2, while articulating on strain rod tower, be connected with insulation operating joint by the detachable joystick of employing, the structure of its disclosed insulation operating joint cannot realize with joystick and is connected fast and separates, and is therefore difficult to realize on large corner strain rod tower articulate fast earth connection; 3, owing to will utilizing wire clamp deadweight to clash into wire, be therefore respectively provided with balancing weight in wire clamp outside, make the weight of this device larger, be not easy to when operating personnel climb shaft tower and operation carry, increased operation intensity and danger; 4, while dismounting, will exert oneself upwards to pull insulating cord and overcome the elastic force of position, top spring, wire clamp is extracted from wire the most at last, not only removes and requires great effort, and the operating personnel when excessive that exert oneself easily cause danger, but also can cause certain damage to transmission pressure.

The patent No. is that CN201010140702.1 discloses a kind of electric power line pole tower grounding wire device and articulated instrument, and this device exists grounding wire device two-end structure inconsistent, and two ends imbalance articulates the difficult problem of grasping of process central bearing point.

Utility model content

Inconsistent for grounding wire device two-end structure in prior art, two ends imbalance, articulates the difficult problem of grasping of process central bearing point.The invention provides one simple in structure, tear open and hang R type earthing wire clip easily.

To achieve these goals, the technical solution adopted in the utility model is: R type earthing wire clip, comprises insulating bar, insulating bar top fixation spring tab, makes shell fragment and insulating bar be R shape, shell fragment other end steady brace, pull bar other end fixed pulling rope, fixes pole on pull bar.

Nature, pole free end is greater than cable diameter to the distance of insulating bar, and shell fragment crooked position to the distance of insulating bar is less than cable diameter.

The beneficial effects of the utility model are: 1, the utility model is simple in structure, easy to use, operating process is time saving and energy saving, operating efficiency is high, can on various shaft towers, realize that hanging earthing conductor is disposable to be completed, by the induced effect of R type hanging head and stay cord, can complete the installation and removal of wire clamp.2, security performance is high, can guarantee operating personnel's personal safety, and from heavy and light, be easy to carry; Remove laborsavingly, make operation safer, and can not cause any damage to transmission pressure.

Fig. 2 is the structural representation of installment state of the present utility model;

Fig. 3 is the structural representation of disassembly status of the present utility model.

Embodiment

As shown in Figure 1, R type earthing wire clip, comprises insulating bar, and insulating bar 1 top fixation spring tab 2 makes shell fragment 2 and insulating bar 1 be R shape, shell fragment 2 other end steady braces 3, and pull bar 3 other end fixed pulling ropes 5, fix pole 4 on pull bar 3.Nature, pole 4 free ends are greater than cable diameter to the distance of insulating bar 1, and shell fragment 2 crooked positions to the distance of insulating bar 1 is less than cable diameter.

As shown in Figures 2 and 3, R type earthing wire clip hook method, 1) stay cord 5 is striden across to cable; 2) cable is placed between insulating bar 1 and pole 4; 3) pull stay cord 5, stay cord 5 drives pull bar 3, and shell fragment 2 crooked positions are opened, and 4) cable is placed in to R type earthing wire clip head, unclamp stay cord 5, shell fragment 2 clamps cable, ground connection; 5) pull stay cord 5, stay cord 5 drives pull bar 3, makes 4 of poles on insulating bar 1, by being pushed into cable on insulating bar 1 and being positioned at the fulcrum place of insulating bar 1 and pole 4, unclamps stay cord 5, unloads R type earthing wire clip.
