Embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Referring to Fig. 1-5, a kind of earth connection is installed Special assisting tool, comprise insulating bar 12 with and top be provided with for clamping manipulator, the bottom of ground wire bar, be provided with that manipulator is opened and closed operating grip for controlling; Manipulator comprises by universal joint 8 and is hinged on the fixed part 1 on insulating bar 12 tops and the movable part 2 hinged with the middle part of fixed part 1, and the front end of movable part 2 is connected with the rear end of fixed part 1 by tension spring 7; Operating grip comprises and is positioned at the tooth bar 5 in insulating bar 12 lower pole chambeies, the housing 11 that is fixed on insulating bar 12 outer walls, the plectrum 10 that is hinged on housing 11 inner sides and the unidirectional stopping means 6 of tooth bar, plectrum 10 is installed torsion spring with the hinged place of housing 11, and plectrum 10 middle parts are provided with handle 9, plectrum 10 rotation rearward end can with tooth bar 5 on tooth engagement; Tooth bar 5 tops connect insulating trip 4, upper and lower is fixed with respectively horizontal location bar 13, and the length of horizontal location bar 13 is slightly less than the internal diameter of insulating bar 12; Insulating trip 4 is by the rear end of bracing wire 3 movable part connectings 12, and movable part 12 can and coordinate with the breach of fixed part 1 front end around fixed part 1 rotation and clamp ground wire bar under bracing wire 3 pulling force; The unidirectional stopping means 6 of tooth bar is for laterally running through the concentric reducer structure of insulating bar, wherein the be provided with horizontal slotted eye 6.2, microcephaly at stub end 6.1 middle parts are held and on 6.5, are set with back-moving spring 6.3, and one end of back-moving spring 6.3 and stub end 6.1 against, the other end and insulating bar 12 inwalls against; Tooth bar 5 runs through slotted eye 6.2, in slotted eye 6.2, be fixed with tooth bar 5 on the unidirectional positioning tooth 6.4 of tooth engagement, the upper surface of the tooth on the lower surface of unidirectional positioning tooth 6.4 and tooth bar 5 is that inclined-plane coordinates, when tooth bar 5 is stressed will move down time, thereby the tooth on tooth bar 5 can be coordinated and be promoted unidirectional positioning tooth 6.4 and move laterally and remove engagement fit by inclined-plane.
During use, by squeeze grip 9(according to the direction of arrow in Fig. 3), plectrum 10 front ends coordinate by the tooth with on tooth bar 5 that to press down tooth bar 5 descending, unidirectional positioning tooth 6.4 is at the compressing lower compression back-moving spring 6.3 of tooth bar 5 move right (with reference to Fig. 5), when tooth bar moves down after a tooth pitch, unidirectional positioning tooth 6.4 can move to left and again mesh with the tooth of tooth bar 5 under the effect of back-moving spring 6.3, when pressing down continuously handle 9, tooth bar 5 can move down continuously, and can be by the unidirectional stopping means 6 of tooth bar, tooth bar 5 is fixing in place, horizontal location bar 13 can keep the horizontal scope of activities of tooth bar 5 to be positioned at all the time near the central authorities of insulating bar 12, horizontal location bar 13 both sides and insulating bar 12 keep suitable gap, prevent that the two is because surprisingly blocking and cause tooth bar 5 to move.When tooth bar 5 moves down, can strain successively insulating trip 4, bracing wire 3 makes movable part 2 around fixed part 1 rotation, the breach of the front end of movable part 2 and fixed part 1 front end gradually near and clamp ground wire bar (unidirectional positioning tooth 6.4 locking racks 5 of bottom), tension spring 7 is in extended state; Now can support ground wire bar, fix its position, angle, can be so that operatively the personnel of line bar be more laborsaving, and reduce rocking of ground wire bar, improve installation effectiveness and also reduce risk.After installing, press the stub end 6.1 of the unidirectional stopping means 6 of tooth bar, the locking that can remove unidirectional positioning tooth 6.4 tooth bars 5 coordinates, then by the pulling force of tension spring 7, movable part 2 reverse rotations, the breach of the front end of movable part 2 and fixed part 1 front end gradually away from and unclamp ground wire bar, in the process of movable part 2 rotations simultaneously, strain successively bracing wire 3, insulating trip 4, thus on carry tooth bar 5 and get back to initial position, to this operating process, complete and can carry out next operating process.
For those skilled in the art, under the premise without departing from the principles of the invention, likely to concrete size, or partial structurtes make some improvements and modifications, and these improvements and modifications also should be considered as protection scope of the present invention.
