Background technology
In electric system, goaf（The bad area of geology）Caused electric power line pole tower tilt phenomenon happens occasionally so that
The sag of conductor and ground wire being connected with shaft tower changes with the tilt variation of shaft tower, causes to lead（Ground）Line stress is more than design tension, gives
Safe operation brings threat；Therefore, goaf（The bad area of geology）After shaft tower tilts, ensure the primary of transmission line safety operation
Measure is release grounded-line tension, makes grounded-line tension in the range of design safety.
At present, strain rod tower is generally fixedly connected with the connection mode of grounded-line, and the adjustment of this structure needs mostly
Line outage adjusts；Yet with goaf and the bad area's shaft tower tilt variation of geology frequently, it is necessary to adjust in time, otherwise having can
The accidents such as the broken string of falling tower can be caused to occur（Especially small span）, it is more and frequent to adjust workload.
To solve the problems, such as that tension can not discharge in time, the generation of the serious accidents such as tower, broken string is avoided down, reduces operation wind
Danger and human and material resources, financial resources waste, and a kind of adaptive shaft tower grounded-line tension release device is just particularly important.
The content of the invention
The present invention overcomes the shortcomings of the prior art, and technical problem to be solved is：There is provided a kind of release of tension and
When shaft tower grounded-line tension release device.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
Shaft tower grounded-line tension release device, the connection gold being connected including release device body and with release device body
Tool, the release device body are aduncate arc-shaped side in isosceles triangle platy structure and base；The release device
It is provided on body：Shaft tower connecting hole, fixed voussoir, control pin and crescent sliding slot；The shaft tower connecting hole is arranged on release
The center of top of device body, the crescent sliding slot are arranged on the bottom of release device body, and the fixed voussoir is arranged on
Between shaft tower connecting hole and crescent sliding slot, the control pin is two and is symmetricly set on the both sides of fixed voussoir, the moon
Leaf spring is provided between thread form sliding slot and control pin, roller is provided in the crescent sliding slot, the roller is with being connected
Gold utensil is connected, and grounded-line connecting hole is provided in the connection gold utensil.
Preferably, the connection gold utensil is y-type structure, and fixation is both provided on the V-type end of the connection gold utensil upper end
Hole, the mounting hole are connected by bolt with release device body, and the grounded-line connecting hole is arranged on connection gold utensil lower end
On montant.
Preferably, the leaf spring behaviour font structure.
Preferably, the release device body is made of integral type steel construction.
Preferably, the load capacity of the release device body is determined by the maximum working tension of grounded-line.
The present invention has the advantages that compared with prior art.
Release device body can be series in grounded-line and is connected with shaft tower by the present invention, grounded-line connecting hole and grounded-line
Connection when wire tension caused by the shaft tower tilt variation in goaf or the bad area of geology is more than tension allowable, passes through connection
Gold utensil starts leaf spring and flexible deformation occurs, and connection gold utensil rolls along crescent sliding slot under the driving of roller, reaches and release
It puts tension and adjusts the purpose of line length, the serious accidents such as the broken string of falling tower is avoided to occur, ensure line security operation.
