Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 1 be the tool assembly of a kind of charged for replacement insulator string of the present utility model, the tool assembly of this charged for replacement insulator string comprises: shaft tower cross-arm jig 1 and leading screw hoisting apparatus 2, wherein, shaft tower cross-arm jig 1 comprises: two jig body 11 and waling stripe 12.
As shown in Figure 2, two jig body 11 have respectively along horizontal-extending to be connected to cross-arm buckling groove 111 on the shaft tower cross-arm and the leading screw mounting groove that extends longitudinally, and waling stripe 12 connects also strains two jig body 11.Leading screw hoisting apparatus 2 comprises: leading screw 21, screw 22 and suspension hook 23, leading screw 21 are arranged in the leading screw mounting groove, and screw 22 is installed in the upper end of leading screw 21 and is supported on the jig body 11, and suspension hook 23 is connected to the lower end of leading screw 21.
As shown in Figure 3, the shaft tower cross-arm jig 1 of the tool assembly of charged for replacement insulator string makes full use of the partial structurtes of shaft tower cross-arm, cross-arm buckling groove 111 has and the angle bar of the shaft tower cross-arm structure of clamping mutually, the angle bar of shaft tower cross-arm just in time blocks the cross-arm buckling groove 111 of two jig body 11, make suspension hook 23 and leading screw 21 be positioned at insulator string to be replaced lead directly over, suspension hook 23 catches on lead, rotate screw 22 then, as shown in Figure 1, regulating handle 24 is installed on the screw 22, regulating handle 24 can rotate screw 22 in convenient labour-saving, further preferably, regulating handle 24 extends along the radial level of screw 22, and the moment of torsion of regulating handle 24 can keep bigger like this, and rotation screw 22 is convenient laborsaving.When leading screw 21 is moving upward along with the rotation of screw 22, suspension hook 23 catches on lead, wire weight mechanical load and electric insulation function that former cause insulator string is born are transferred on the tool assembly of charged for replacement insulator string, thereby replacing insulator string that can safe ready, the tool assembly weight capacity that has overcome charged for replacement insulator string of the prior art is poor, the technical problem that insulation level is low, and its stability is high, weight capacity is good, and has higher insulation level.
Fig. 1 again, preferred embodiment a kind of according to leading screw hoisting apparatus 2 shown in Figure 1, leading screw hoisting apparatus 2 also comprises insulated tension pole 25, suspension hook 23 is connected to the lower end of leading screw 21 by insulated tension pole 25.Insulated tension pole 25 can guarantee insulation between tool assembly when work suspension hook 23 of charged for replacement insulator string and the leading screw 21, thereby has improved the insulation level of the tool assembly of charged for replacement insulator string, avoids external environment influence such as humidity, surface is dirty.
As preferred embodiment a kind of, from Fig. 1, Fig. 2 and Fig. 3, can see, waling stripe 12 comprise respectively with two end linkage sections 121 that are connected of two jig body 11 and two ends respectively with the intermediate regulations connecting rod 122 of two end linkage section 121 bolts, the length that can utilize intermediate regulations connecting rod 122 to regulate whole waling stripe 12 like this, thereby reach the effect that two jig body 11 of tension are come the turning torque of balance shaft tower cross-arm jig 1, make the big corner angle of shaft tower cross-arm only be subjected to vertical stress component.
Preferably, can see from Fig. 1 and Fig. 2 that waling stripe 12 is hinged with two jig body 11 respectively.Since may be out-of-level with the position of the local angle bar of two jig body 11 corresponding shaft tower cross-arms, waling stripe 12 and two jig body 11 hinged connected modes still can realize straining the effect that two jig body 11 are come the turning torque of balance shaft tower cross-arm jig 1.
By Fig. 1 and Fig. 3 as can be seen, screw 22 is a ball-crown body with the contact jaw of jig body 11, and the upper surface of jig body 11 is provided with the spherical groove 112 that matches with ball-crown body.It is laborsaving flexibly that such structure makes that rotation screw 22 promotes leading screws 21, avoids angle that leading screw 21 hooks lead owing to suspension hook 23 to change simultaneously being subjected to bending moment fractureing easily.
As shown in Figure 3, the side of jig body 11 also is provided with the briquetting 113 that has the Long Circle groove, and briquetting 113 and jig body 11 are connected by the Long Circle groove and are arranged in the end of angle bar of the shaft tower cross-arm of cross-arm buckling groove 111 with backstop.When the angle bar of shaft tower cross-arm snaps in cross-arm buckling groove 111, briquetting 113 can move along the Long Circle groove, and then push against angle bar, prevent angle bar slippage from cross-arm buckling groove 111, strengthened the stable and fastness of clamping, make it can adapt to the angle bar structure of three layers of cross-arm of shaft tower simultaneously, have wide range of applications.
Be it can also be seen that by Fig. 1, Fig. 2 and Fig. 3 the side of the leading screw mounting groove on the jig body 11 offers construction opening, the construction opening place is provided with horizontally extending clamping screw 114.Leading screw 21 is installed in the leading screw mounting groove by construction opening, be locked by clamping screw 114 again, be convenient to the installation of kit, simultaneously since an end of clamping screw 114 be fixed on the jig body 11, make its unlikely because operate miss comes off the staff of danger to the below.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
