Embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure: the multipurpose strain insulator porcelain vase among the embodiment more changing device mainly is made up of hanger 8, load screw mandrel 2, transmission mechanism and ratchet spanner more than 1 parts.
As shown in Figure 1; Said hanger 8 is used to be fastened on the steel pipe iron tower, and hanger 8 is provided with brace table 8a, and brace table 8a is provided with the through hole that runs through up and down; Said load screw mandrel 2 vertically is provided with and in through hole, passes; Load screw mandrel 2 lower ends are provided with the connector 2a that is used to connect the strain insulator porcelain vase, and transmission mechanism is installed on the load screw mandrel 2, and transmission mechanism is used to drive load screw mandrel 2 and moves axially up and down.
As shown in Figure 1; Said transmission mechanism is positioned at the top of hanger 8 brace table 8a; Transmission mechanism mainly by ratchet spanner 1, cover 3 thoroughly, swivel nut 4, end cap 5, thrust ball bearing 6 and bracket 7 form, swivel nut 4 is assemblied on the load screw mandrel 2 and forms the screw thread transmissions with load screw mandrel 2 and cooperates, swivel nut 4 peripheries are provided with and are used for the ratchet 4a that matches with ratchet spanner 1; The ratchet 4a that said ratchet spanner 1 head end is enclosed within swivel nut 4 goes up and locks through covering 3 thoroughly; Said bracket 7 is positioned at swivel nut 4 belows, and bracket 7 sizes are greater than clear size of opening, and bracket 7 bottom supports are on hanger 8 brace table 8a; Said thrust ball bearing 6 is contained in the bracket 7 and through end cap 5 encapsulation, said swivel nut 4 lower ends are supported on the thrust ball bearing 6.
The structure of said hanger 8 is specifically as shown in Figure 2, and hanger 8 one sides are the brace table 8a that are used for rest load screw mandrel 2; The top of said hanger 8 opposite sides is provided with two link plate 8b, is connector between two link plate 8b, is fitted with on two link plate 8b to be used for hanger 8 is connected the pin on the steel pipe iron tower; The bottom of said hanger 8 opposite sides is provided with two clamp 8c, is draw-in groove between two clamp 8c, and this draw-in groove is used for directly clamping and is fixed on the steel pipe iron tower.
Like Fig. 1, shown in Figure 2, said bracket 7 lower surface are made as arcwall face, and the aperture of said through hole is provided with fillet surface, and the arcwall face of fillet surface and bracket 7 forms face face contact matching.The edge, aperture that can prevent through hole like this causes damage to bracket 7.
Shown in Fig. 3 .1, Fig. 3 .2, have limited impression 2b on the said load screw mandrel 2 along its length direction; Shown in Fig. 4 .1 ~ Fig. 4 .3, the inwall of said bracket 7 centre bores is provided with spacing block set 7a; During assembling, load screw mandrel 2 is located in bracket 7 centre bores, but the spacing block set 7a on bracket 7 center bore inner walls is embedded in the limited impression 2b on the load screw mandrel 2 and slide relative.Match with spacing block set 7a through limited impression 2b; Can prevent that load screw mandrel 2 from rotating; Help on the one hand swivel nut 4 and cooperate, can avoid on the other hand damaging the strain insulator porcelain vase owing to the rotation of load screw mandrel 2 with formation screw thread transmission between the load screw mandrel 2.
The concrete applicable cases of the utility model is following:
1, at first the hanger in the utility model 8 is fastened on above the fixture of steel pipe iron tower; Connect fixed form and have two kinds: a kind of is with pin two link plate 8b on hanger 8 tops to be connected with the fixture of steel pipe iron tower to fix, and pins and bears shear force; Another kind is that hanger 8 is stuck in through its underpart draw-in groove on the fixture of steel pipe iron tower, and hanger 8 relies on self gravitation to guarantee to be connected reliably with pulling force.
