Abstract
The utility model discloses a charged fastening screw device, which comprises a hollow insulating rod, wherein a gear frame is fixed at the upper end of the hollow insulating rod; at least three support rods are hinged on the lower part of the hollow insulating rod; the hinged points of the three support rods are positioned on the same plane of the hollow insulating rod; an operating rod is sleeved in the hollow insulating rod, and is fixedly connected with the gear frame through a bearing; the end part of the operating rod which extends out of the bearing is provided with a bevel gear set; a bolt sleeve is connected with a bevel gear set through the gear frame; and the lower end of the operating rod is provided with a handle. Due to the adoption of the technical scheme, the charged fastening screw device has the advantages that: in a use process, the bolt sleeve of a specification which corresponds to that of a bolt is used, the lengths of the hollow insulating rod and the operating rod are adjusted, and the support rod is supported on the ground, so that convenience is brought to operation; and a handle is rotated for driving the operating rod, the bevel gear set and the bolt sleeve to rotate, and a screw fastening or screw loosening action is adjusted by adjusting the handle rotating direction.
Description
Technical field
The utility model relates to a kind of instrument that is used for charged fastening high-tension overhead line screw.
Background technology
Need the parts that be connected between lead on the high-tension overhead line and gold utensil, gold utensil and the tower, majority is used the screw connection.The instrument of holding screw generally comprises down dop and the upper chuck that is used for holding screw; The upper chuck structure is following: go up the insulating bar head and connect rotational connector with bolts and nuts; Tube connector connects rotational connector with bolts and nuts, and the very heavy spanner that extends is inserted in the tube connector, and wrench socket is inserted on the very heavy spanner of lengthening; Gripper shoe is hinged on the connecting plate on the tube connector; Following dop structure is following: following insulating bar head also is being equipped with anti-rotation device, strap wrenches on the joint on the insulating bar down by the bolts and nuts joint.This instrument has following deficiency: poor stability, and insufficient strength, when on being directed against high pressure overhead power line, using especially, insulating bar falls short of, and can not satisfy actual needs; Complicated operation on the other hand, bolt comes off easily in the operating process; The effect of fastening bolt is played through the rotary manipulation bar in the free-hand bottom of catching action bars, but the difficulty of rotation is particularly operated inconvenience more to higher bolt.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency a kind of charged holding screw device is provided.
The purpose of the utility model realizes through following technical scheme:
A kind of charged holding screw device comprises hollow insulating bar, and the upper end of hollow insulating bar is fixed with tooth rest; The bottom of hollow exhausted bar is hinged with three support bars at least, and the pin joint of three support bars is on the same plane of hollow insulating bar, in hollow insulating bar, is arranged with action bars; Action bars is connected through bearing and tooth rest; The action bars end of stretching out bearing is provided with bevel reduction gear set, and bolt collar connects bevel reduction gear set through tooth rest, is provided with handle in the action bars lower end.
Above-mentioned charged holding screw device has break joint between said bevel reduction gear set and the tooth rest.
Adopt technique scheme; The utility model has following advantage: select for use during use and the corresponding bolt collar of bolt specification, adjust the length of hollow insulating bar and action bars, then with they sup-port on the ground; Make it to be convenient to operation; Turning handle drives action bars, bevel reduction gear set and bolt collar rotation, the action that the adjusting of the direction through turning handle is regulated holding screw or unscrewed screw.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of charged holding screw device as shown in Figure 1; Comprise hollow insulating bar 4, the upper end of hollow insulating bar 4 is fixed with tooth rest 3, and the bottom of hollow exhausted bar 4 is hinged with three support bars 7 at least; The pin joint of three support bars 7 is on the same plane of hollow insulating bar; In hollow insulating bar 4, be arranged with action bars 5, action bars 5 is connected through bearing and tooth rest 3, and the action bars end of stretching out bearing is provided with bevel reduction gear set 1; Bolt collar 2 connects bevel reduction gear set 1 through tooth rest, is provided with handle 6 in action bars 5 lower ends.Between said bevel reduction gear set 1 and the tooth rest break joint is arranged, to reduce the friction between bevel reduction gear set and the tooth rest.
