Description
Technical field
The present invention relates to power overhead network constructions and service kit more particularly to a kind of electric stringing to lead tight adjustable jaw
Gripper.
Background technique
Gripper is constructed as a kind of power overhead network and service kit, is made extensively in power industry for a long time
With function, specification, model are also not quite similar, but its most basic function is exactly, the adjustment arc for overhead power line
It hangs down, fixed strain.Due to tightening to be realized and the purpose of conducting wire is tensed, this requires the jaws of gripper will be completely by conductor grip
Grip jail.And the design of the problem that gripper in the prior art is not reasonable in the prevalence of whole design, especially jaw
Defect is easy to appear cable and clamps shakiness on gripper, and cable skids in cable clamping interface, or even the phenomenon that will appear slippage,
Form accident potential.Gripper part is too many simultaneously, and structure is complicated, and cable gripper is that special line is dedicated, poor universality.
Summary of the invention
The present invention provides a kind of electric stringing and leads tight adjustable jaw gripper for above-mentioned the deficiencies in the prior art.
Electric stringing of the invention leads tight adjustable jaw gripper, by substrate, stretch ring, connecting rod, jaw mandibular plate, on
Jaw plate is constituted, and substrate is triangular shape, and there is the parallel guide chute of connecting rod of hollow out at bevel edge to the base angle on substrate along side, from
Apex angle to bottom edge is provided with the arcuate guide sliding slot of mandibular plate, there is fixed attaching along the middle part to the substrate at another base angle of bottom edge
Jaw maxillary plate；Slide-bar pass through connecting rod parallel guide chute one end of stretch ring and connecting rod is mutually hinged, the other end of connecting rod with
One end of the bracket of mandibular plate is mutually hinged, and the other end and another base angle of substrate and maxillary plate of bracket are mutually hinged, mandibular plate
Midpoint is mutually hinged with bracket, and the inner end of mandibular plate has sliding pin in arcuate guide sliding slot, and maxillary plate and mandibular plate are same
In one plane, both opposite parallel edges is the jaw for the occlusion being parallel to each other.
As a further improvement of the present invention, it is that the jaw of mandibular plate has been embedded in rack gear in parallel, the rack gear is in parallel
It is embedded in the groove of mandibular plate jaw.
As a further improvement of the present invention, it is tooth engaged is distributed on the vice jaw surface of rack gear, there is matching for gap at the back side
Two jackscrews of insertion are closed, which is horizontally through mandibular plate and with the back side of mandibular plate mutually for tight.
As a further improvement of the present invention, it is to be evenly equipped in the maxillary plate opposite plane parallel with the two of mandibular plate
Tooth engaged.
Electric stringing of the invention leads tight adjustable jaw gripper, is realized using the design of link mechanism combination sliding slot pair
The occlusion school of cable is tight, and when pulling force is bigger, then its bite force is bigger, guarantees that cable is persistently clamped during drawing and leads
It draws；The mandibular plate activity of gripper jaw of the invention simultaneously has been embedded in rack gear, realizes further holding with a firm grip to cable, reduces
Strip line accident, improves working security；Simultaneously its jaw can also be conveniently adjusted according to different types of cable configurations
Bore, to adapt to various construction requirements；Electric stringing of the invention leads tight adjustable jaw gripper, overall construction design rationally,
It is compact, easy to use, suitable for the construction demand under the conditions of various.
Detailed description of the invention
Fig. 1 is positive structure schematic of the invention；
Fig. 2 is structure schematic diagram of the invention；
Fig. 3 is the structural schematic diagram that jaw of the invention opens.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1, 2, 3, electric stringing of the invention leads tight adjustable jaw gripper, be by substrate 1, stretch ring 2, connecting rod 3,
Mandibular plate 4, the maxillary plate 5 of jaw are constituted.The substrate 1 is similar triangle, and the bevel edge along side is to one on substrate 1
There is the parallel guide chute 6 of the connecting rod of hollow out at base angle, is provided with the arcuate guide sliding slot 7 of mandibular plate 4 from apex angle to bottom edge, along bottom edge
There is the fixed jaw maxillary plate 5 attached on substrate 1 at portion to another base angle；Slide-bar 9 passes through the parallel guide chute 6 of connecting rod and will lead
Pull ring 2 and one end of connecting rod 3 are mutually hinged, and one end of the bracket 8 of the other end and mandibular plate 4 of connecting rod 3 is mutually hinged, bracket 8 it is another
One end and another base angle of substrate 1 and 5 phase of maxillary plate are hinged, midpoint and 8 phase of the bracket hinge of mandibular plate 4, mandibular plate 4 it is interior
Side has sliding pin 10 in arcuate guide sliding slot 7, and in the same plane, the parallel edges of both is for maxillary plate 5 and mandibular plate 4
Be parallel to each other the jaw of occlusion, is evenly equipped with tooth engaged in the opposite plane parallel with two of mandibular plate 4 of maxillary plate 5.
The jaw of mandibular plate 4 has been embedded in rack gear 11 in parallel, which is embedded in the groove of 4 jaw of mandibular plate in parallel
In, biting teeth is distributed on the vice jaw surface of rack gear 11 to increase coefficient of friction, enhances its bite force on local keypoint part；?
There are Embedded two jackscrews 12 of clearance fit on the back side of rack gear 11, which is horizontally through mandibular plate 4 and and mandibular plate
4 back side is mutually standby tight.In the Embedded top line connection type of clearance fit of rack gear 11 and jaw, it can be achieved that jaw opens and closes size
The replacement of adjustable and different rack gear enhance versatility of the invention to be adapted to different cable shapes.
