The device comprises a terminal clamping device, connecting wires, an earthed terminal clamping device, and an operation mechanism, and the terminal clamping device is provided with a blocking mechanism which comprises a press lock [5], a press spring [6], a press cap [7], and a locking hole [8]; the operating mechanism is matched with the blocking mechanism on the terminal clamping device, which can conveniently dismount the earthed wire. The portable earthed device can be uses as the attaching earthed wire for the lines below 220KV and the repair lines of the substation tower beyond the 35KV.
Description
A kind of appliance maintenance equipment.
The prior art of this technical field discloses terminals anchor clamps in the patent (DS2702-648), the earth terminal clamp structure is identical, the device that connects with lead in the middle of the two, and the main body of anchor clamps is a hollow garden pipe, and clamp system is housed on the main body.This apparatus structure is simple, and is easy to carry, but operates very trouble, and tearing hanging wire open needs the staff to roll off the production line, and working strength of workers is very big like this, also is danger close simultaneously.The device of another invention (DS2640-916) is that grounding wire device has the mounting or dismounting hanging wire that mechanical structure is controlled terminals, and this device operation is very convenient, but structure is huge, the manufacturing cost height, and carry very inconvenient.Owing to there is not handy grounding wire device.Overhaul circuit to operating personnel and bring all difficulties, designing a kind of suitable grounding wire device has become urgent need.
Task of the present utility model is to overcome the problem that existing grounding wire device exists, and designs a kind of grounding wire device simple in structure, easy to operate, portable.
Task of the present utility model realizes as follows, grounding wire device is made of terminals anchor clamps, connecting line, earth terminal anchor clamps and operating mechanism, and the terminals anchor clamps comprise shell (1), lever arm (2), compression spring (3), also have one between shell and lever arm tears the blocking mechanism that hanging wire is used open.
The grounding wire device that the utility model disclosed as shown in the figure.Blocking mechanism on the terminals anchor clamps is by pressing lock (5), stage clip (6), pressure cap (7) and locking hole (8) to form.The operation principle of this retaining mechanism is: when tearing hanging wire open, need only use the hook on the operating mechanism (can install hook on action bars or the connecting rod) to insert in the shell reinforcement plate hole (11), make the certain distance (greater than the high-voltage line diameter) of generation between shell and the lever arm when pad (5) is aimed at locking hole (8), pad just enters locking hole under the effect of stage clip (6) become one shell and lever arm, the two can not relative motion, at this moment the opening between shell and the lever arm opens, and anchor clamps can remove from high-voltage line easily.
The operating mechanism that the utility model disclosed is used for terminals are clamped and pull down high-voltage line.Operating mechanism can be made up of action bars or action bars and connecting rod, and action bars is a joint, and connecting rod can be according to the length of using needs by forming more than the joint.
Action bars is made up of operating grip (12), insulating coating (13), push rod (14), locked groove (15), pin (16), insulated tube (18), spring (19), hollow push rod (20), joint axis (21) and pin (22).During the action bars hanging wire, at first action bars is inserted terminal tails portions, at this moment the pin on the action bars (22) enters the L type groove on the shell, after the bellmouth on action bars top and the positioning sliding block (4) closely contacts, action bars is turned clockwise 90 °, pin (22) just fuses the insulating coating on the action bars and coupling spindle and shell, continuation pushes inward operating grip, form catch bar just with lever arm jack-up by push rod (14) and hollow push rod (20), opening between shell and the lever arm is opened, continue 90 ° of clockwise direction rotating operating handles, pin (16) on the push rod (14) just enters locked groove (15), make push rod at jack-up terminals anchor clamps lever arm, the push rod and the insulating coating of lock operating lever under the opening open configuration between shell and the lever arm, make that the two can not relative motion, simultaneously also lock shell and the lever arm under the open configuration, like this, utilized action bars to lift just hanging wire easily of terminals anchor clamps.
Behind the hanging wire, action bars need only be rotated counterclockwise 90 °, pin just withdraws from L type groove under the effect of compression spring (3), thereby at this moment the opening between shell and the lever arm is closed clamping wire.
When high-voltage line is overhead very high, during with action bars hanging wire curtailment, can connect a joint or the above connecting rod of a joint.Connecting rod is made up of fitting sleeve (30), conductive bar (31), insulating bar (23), insulating coating (24), pipe plug (25), push rod (26), spring (27), pin (28), joint axis (29).Its effect mainly is to be used for connecting, make the operating mechanism lengthening, when needs add connecting rod, just the top end with action bars inserts the connection tail end, at this moment the pin (22) on the action bars coupling spindle enters in the L type groove (32) of connecting rod tail end, and 90 ° of the action bars of turning clockwise then, pin (22) and L type groove (32) just fuse the two insulating coating of action bars and connecting rod, the push rod of the two also becomes one, just can with action bars with same workman's operate.
The terminals anchor clamps, the shell and the lever arm of earth terminal anchor clamps are pressed cast molding by aluminium alloy, a shell and lever arm folder mouthful corresponding position up and down all has groove, makes it contact closely, and the shell of terminals anchor clamps and the compression spring between the lever arm (3) material can be selected general spring steel for use.
The utility model since on the terminals anchor clamps design and installation blocking mechanism.Just can pull down anchor clamps easily automatically, must the staff not roll off the production line and tear hanging wire open, shorten the operating time like this, alleviate working strength of workers.Avoided danger.Thereby the form that operating mechanism adopts a joint action bars to add any joint connecting rod makes device easy to use, is easy to carry.The shell of conductor wire end jig and lever arm adopt aluminium alloy to press cast molding, have so just strengthened the intensity of anchor clamps, have prolonged useful life, have also alleviated the weight of device simultaneously.
A kind of embodiment of the present utility model is illustrated by accompanying drawing.
Accompanying drawing one is the front section view of the utility model terminals anchor clamps, (1) is that shell (2) is a lever arm among the figure, (3) be spring, (4) are positioning sliding block, (5) pad, (6) stage clip, (7) pressure cap, (8) locking hole, (9) tapered hole, (10) L type groove, (11) strengthen plate hole.
