Embodiment
Below in conjunction with instance the present invention is carried out detailed explanation.
The contact-making surface compounding technique that the bearing capacity system of the rational lever linkage of this patent and jaw and expanded conductor are best provides a kind of suitable expanded conductor anchoring, and has met the fixing-line device of construction reference requirement.
The conductive wire cross-section sketch map of the multi-form hole enlargement structure that Fig. 1 to Fig. 4 is suitable for for the present invention.Fig. 1 expanded conductor inner ring is all found time, and steel core is used wrapped with insulation, supports two-layer aluminium single line with the cross high density polyethylene (HDPE) again; The middle level aluminum steel of Fig. 2 and Fig. 3 expanded conductor is taken out thigh in proportion, and is loosely organized, unbalance stress.Fig. 4 is another form expanded conductor.Because the contact force of conductive line surfaces can not be transmitted uniformly; The stretching resistance of lead reduces; Pressurized position easy deformation, diameter of wire and nominal operation load are unprecedented in addition, technology of the present invention mainly is rationally to solve between this fixing-line device normal pressure and the frictional force; Slippage and lead damage; The intrinsic contradictions of load and weight.Through the lever ratio L1 between the linkage hinged joint: L2: L3 (lever force system) and jaw shape and Rational Parameters coupling, make its stressed system be in optimum state, reach not slippage when guaranteeing grip, the result of damage wires not.
Fig. 5 is common three layers of aluminum conductor cross-sectional structure sketch map.
Fixing-line device is in the construction of stringings such as unwrapping wire, broken string, stringing, annex installation, necessary connection class Work tool when setting up lead and need anchoring, and what be used for being set up any position of lead all kinds ofly faces the clamping system that anchor and stringing bear.Fig. 6 be the expanded conductor fixing-line device in the transmission line construction under tension stringing, the working state schematic representation during clamping wire.Fixing-line device will born 25% transmission with the upper conductor pull-off force in anchor system.In the construction, fixing-line device and anchor rope (pull rope) are connected with expanded conductor, make the tension force of lead pass to anchor line, realize the folding and unfolding lead, adjustment lead sag, lead butt joint, annex installation and restringing etc.
Fig. 7 is an expanded conductor fixing-line device structural representation, and this structure is a lever connecting rod formula mechanism, and its fixing-line device is mainly by train wheel bridge 3, fixed pressuring plate 4, draw ring 5, arm-tie 6, spring clamping part 7 and dynamic pressure plate 8.Fixed pressuring plate 4 is provided with chute 9, and chute 9 connects along the fixing-line device thickness direction, and chute 9 has 2 end points, is defined as the remote point of chute 9 near the end points at fixed pressuring plate 4 edges, is defined as the proximal points of chute 9 near fixed pressuring plate 4 inner end points.This mechanism is applied with external force by draw ring 5, and in clamping expanded conductor 1 process, external force is the pulling force of stressed system, and pulling force is through arm-tie 6 power transmissions to dynamic pressure plate 8, train wheel bridge 3, lead 1 and fixed pressuring plate 4.Because leverage makes lower plate produce the clamping force greater than pulling force, under the effect of clamping force; Expanded conductor and last lower plate produce frictional force, overcome the pulling force of lead, and lead is skidded off; Reach the purpose that grasps lead; At this moment, draw ring 5 is positioned at the position near chute 9 proximal points with the pin joint B of arm-tie 6, and fixing-line device is in the minimal openings state.When fixing-line device 2 dismounting, external force gives the thrust of draw ring 5 for the staff, thrust through arm-tie 6 power transmissions to dynamic pressure plate 8; Draw ring 5 is moved along the level trough on the fixed pressuring plate 4, and promoting arm-tie 6 is that rotate in the axle center with dynamic pressure plate 8 with the E point, and dynamic pressure plate 8 drives on the train wheel bridge 3 and moves simultaneously; Jaw is opened; At this moment, draw ring 5 is positioned at the position near chute 9 remote points with the pin joint B of arm-tie 6, and fixing-line device is in the maximum open state.
Special torsion spring 7 is housed on the arm-tie 6 of fixing-line device 2, and can guarantee is not having external force to do the time spent, produces more effective preparatory clamping force.Need only promote the B point during use, clamping plate open, and lead 1 is positioned in the clamping plate; Unclamp fixing-line device 2, under the effect of torsion spring 7, last lower plate can be clamped lead 1; After applying with external force, owing to be bar thick stick link mechanism, along with the increase of pulling force; Frictional force is also increasing, thereby realizes the function of fixing-line device 2.
Fig. 8 is a fixing-line device main structure parameters sketch map; The present invention considers conductor structure and parameter and to factors such as fixing-line device rated load (putting stringing tension force), serviceability requirements, according to the structural difference of expanded conductor and plain conductor greatly, characteristics that nominal operation load is big design.For this reason, this patent takes concrete technical scheme following:
1) proportioning of appropriate design adjustment power system
Train wheel bridge 3 connects with dynamic pressure plate 8 through hinge at the D point, and the C point slides in the arc chute of fixed pressuring plate 4.The common clamping wire of arc surface of train wheel bridge 3 and fixed pressuring plate 4; At this moment the pulling force of lead is born by two frictional force that contact-making surface produced of last lower plate and lead; For guaranteeing that train wheel bridge keeps translation in the entire mechanism motion, be 52.90 °~52.94 ° of scope definite values to the constraint reaction and the horizontal angle of train wheel bridge with arc groove on the fixed pressuring plate 4; Distance L 1 between linkage hinged joint B, A, the E, L2, L3 are one group of fixed length.
2) appropriateness increases jaw length
Can not engineering demands according to the jaw length L of standard code fixing-line device >=6.5d-20mm design, the present invention studies through design---test---repeatedly, and the selection that obtains expanded conductor fixing-line device jaw length (L) should be: L >=9.25d-20mm; Increasing jaw length is to improve the chucking power of jaw, reduces one of effective measures of the local contact stress of lead, still; Fixing-line device is a lever connecting rod formula mechanism, and for guaranteeing the balance between a connecting rod when the clamping wire, the fixing-line device volume must increase; If the long fixing-line device weight of jaw is excessive, bring very big difficulty to work high above the ground, otherwise; Damage wires then reduces the specified pull-off force of lead.Therefore, jaw length is that lead should be corresponding minimum value under the rational poised state greater than the chucking power of jaw with the contact stress that the frictional force of contact-making surface produces.
3) confirm rational caliper maximum open
The lower plate maximum open is at first according to the diameter of expanded conductor location on the fixing-line device 2, for lead is conveniently put into, is taken out and leave minimum gap, then, the balance of design organization power system on this basis.Usually minimum clearance is not more than 2mm.
4) jaw two ends groove design
By structures shape; Fixing-line device is following in working order, and last lower plate has certain included angle with outer line of force, and its vertical stress component can produce stress to lead in the jaw end and concentrate; For preventing damage or cutting off aluminum steel; The sufficiently long gradient and smooth arc transition must be designed in last lower plate both ends, and its gradient is 1.00: 5.67, and groove length >=30mm.
Fig. 9 is last lower plate jaw structural parameters sketch map, and the present invention increases the containing amount of jaw and expanded conductor, promptly strengthens groove depth and jaw circular arc cornerite.Lead must have certain gap between jaw after by clamp, avoids that train wheel bridge compresses fixed pressuring plate in the loading process, the lead slippage.So groove depth should be less than the lead radius.Go up simultaneously lower plate caliper shape and all adopt the arc surface that fits with the expanded conductor outer surface; When making the lower plate clamping wire and lead mesh together; The female surface of its rounded face is the bigger the better; But not bumping in the time of should clamping with bit is principle, and jaw is reduced to minimum value to the extrusion stress of lead 1.
Figure 10 clamps heavy in section expanded conductor structural representation for jaw, and this figure is under the fixing-line device clamping wire state, fixing-line device and conductive line surfaces contact condition, and at this moment, the smooth arc-shaped surface of lead and train wheel bridge 3 and fixed pressuring plate 4 fits.
Invention has been described according to specific exemplary embodiment here.It will be conspicuous under not departing from the scope of the present invention, carrying out suitable replacement to one skilled in the art or revise.Exemplary embodiment only is illustrative, rather than to the restriction of scope of the present invention, scope of the present invention is by appended claim definition.
