Abstract
A grounding hook of a vertical lead wire comprises a hook body, clamping plates, a base plate and bolts used for connecting the base plated with the clamping plates, semicircular grooves are respectively and correspondingly arranged on matching surfaces of the base plate and the clamping plates, one ends of the clamping plates, which are close to the semicircular grooves, are connected with the base plate via a pin, long slots are arranged on the base plate, and the bolts are inserted into the long slots. The grounding hook of the vertical lead wire is provided with the base plate and the clamping plates, the semicircular grooves are respectively arranged on the matching surfaces of the base plate and clamping plates, , and the lead wire can be clamped when the semicircular grooves are integrated into a full circle. One ends of the clamping plates are connected with the base plate, and the clamping plates are connected with the middle of the base plate via the bolts, so that the grounding hook is convenient in operation, and can be in reliable connection with the vertical lead wire, and personal safety of operators can be guaranteed.
Description
Technical field
The utility model relates to electric power transmission line maintenance servicing unit, specifically is a kind of ground connection hook of vertical lead.
Background technology
Converting equipment in the transformer station needs periodic maintenance, be to guarantee operating personnel's safety, keep in repair or between turn(a)round the city need have a power failure to the equipment of maintenance and ground connection reliably.This a kind of ground connection needs special-purpose earth connection, and earthing clamp is installed on the earth connection.When the lead that needs ground connection is vertical state and since wire clamp self heavily cause it can be along vertical lead to lower slider, cause earth connection flat be difficult to install and install unreliable; And sometimes because of being subjected to the external force effect, earthing clamp also may come off, and makes that earth connection can not reliable ground, can not guarantee operating personnel's safety.
Summary of the invention
The purpose of this utility model is to provide a kind of ground connection hook of vertical lead, and it is unreliable that the ground connection hook of described this vertical lead will solve in the prior art when vertically lead is provided with earth connection ground connection, can not guarantee the technical problem of operator safety.
The purpose of this utility model is achieved through the following technical solutions: it comprises Hook, clamping plate, base plate and the bolt that connects base plate and clamping plate, Hook is located on the base plate, correspondence position is provided with semi-circular recesses on the mating surface of clamping plate and base plate, and clamping plate are connected with base plate by bearing pin near its semi-circular recesses one end.
Be provided with the Long Circle hole on the base plate, shank of bolt is arranged in this Long Circle hole.
Clamping plate are provided with the slotted hole of an end opening, and the openend of this slotted hole is positioned at the end away from its semi-circular recesses, and shank of bolt is arranged in this slotted hole.
Be provided with three clamping plate at base plate by bearing pin.
Semicircle groove medial surface at clamping plate is provided with reticulate pattern, also is provided with reticulate pattern on the semicircle groove of base plate.
The utility model is compared with prior art, and its effect is actively with tangible.The utility model is provided with base plate and clamping plate in the ground connection hook of vertical lead, be respectively equipped with semi-circular recesses on the faying face of this base plate and clamping plate, after cooperating, both constitute a full circle, can carry out clamping to lead, and clamping plate one end links to each other with base plate by bearing pin, and clamping plate are connected by bolt with the base plate middle part, are convenient to operation, this hook can be constituted with vertical lead be connected reliably, guarantee operating personnel's personal safety.
Description of drawings
Fig. 1 is the front view of the ground connection hook of vertical lead of the present utility model.
Fig. 2 is the vertical view of the ground connection hook of vertical lead of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the ground connection hook of the vertical lead of the utility model, it comprises Hook 1, clamping plate 2, base plate 3 and the bolt 4 that connects base plate 3 and clamping plate 2, Hook 1 is located on the base plate 3, correspondence position is provided with semi-circular recesses on the mating surface of clamping plate 2 and base plate 3, semicircle round recessed on clamping plate 2 and the base plate 3 constitutes a full circle, the vertical lead 6 of clamping wherein, and clamping plate 2 are connected with base plate 3 by bearing pin 5 near its semi-circular recesses one ends.Be provided with Long Circle hole 31 on the base plate 3, shank of bolt is arranged in this Long Circle hole.Clamping plate 2 are provided with the slotted hole 21 of an end opening, and the openend of this slotted hole 21 is positioned at the end away from its semi-circular recesses, and shank of bolt is arranged in this slotted hole.Be provided with three clamping plate 2 at base plate 3 by bearing pin 5.
Certainly,, on the semicircle groove of base plate, also be provided with reticulate pattern, can increase the frictional force of clamping plate and base plate and vertical lead, further prevent its downslide if be provided with reticulate pattern at the semicircle groove medial surface of clamping plate.
Claims (5)
