Fig. 1 is the structural representation of an embodiment of slip Distance limiter of the present utility model;
Fig. 2 is the structural representation of another embodiment of slip Distance limiter of the present utility model;
Fig. 3 is the structural representation of another embodiment of slip Distance limiter of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
An embodiment of slip Distance limiter of the present utility model as shown in Figure 1, it is used for limiting the spacing between double bundle conductor upper conductor 41 and the lower wire 42.This slip Distance limiter comprises that the first mounting panel 10, the first pulley assemblies 20 and second pulley assembly 30 of vertical extension are arranged on the first mounting panel 10.
The first pulley assembly 20 can be arranged on the top of the first mounting panel 10 and be in the left side of the first mounting panel 10.The first pulley assembly 20 comprises two first pulleys 21 that can freely rotate.These two the first pulleys 21 are along vertical array, and the upper conductor 41 of double bundle conductor is between them.In the accompanying drawings, although show that upper conductor 41 all contacts with these two the first pulleys 21, but be to be understood that, in the actual job process, these two the first pulleys 21 might only have a pulley to contact with upper conductor 41, also might be to only have portion of time to have pulley to contact with upper conductor 41 in the process that moves the first pulley assembly 20 along upper conductor 41, this depends on that all the operating personnel operates this slip Distance limiter concrete condition at that time.Like this, when the first pulley assembly 20 when upper conductor 41 slides, if one or two in the first pulley 21 contact with upper conductor 41, because the first pulley 21 can freely rotate, then it can roll at upper conductor 41, thereby can not damage the surface of upper conductor 41.
As shown in Figure 1, the second pulley assembly 30 can be arranged on the bottom of the first mounting panel 10 and be in the right side of the first mounting panel 10.The second pulley assembly 30 comprises two second pulleys 31 that can freely rotate.These two the second pulleys 31 are along vertical array, and the lower wire 42 of double bundle conductor is between them.In the accompanying drawings, although show that lower wire 42 all contacts with these two the second pulleys 31, but be to be understood that, in the actual job process, these two the second pulleys 31 might only have a pulley to contact with lower wire 42, also might be to only have portion of time to have pulley to contact with lower wire 42 in the process that moves the second pulley assembly 30 along lower wire 42, this depends on that all the operating personnel operates this slip Distance limiter concrete condition at that time.Like this, when the second pulley assembly 30 when lower wire 42 slides, if one or two in the second pulley 31 contact with lower wire 42, because the second pulley 31 can freely rotate, then it can roll at lower wire 42, thereby can not damage the surface of lower wire 42.
In the embodiment shown in Figure 2, the structure of slip Distance limiter and embodiment shown in Figure 1 are roughly the same, and difference is that the first pulley assembly 20 and the second pulley assembly 30 are arranged on the same side of the first mounting panel 10, such as the left side.
In the embodiment shown in fig. 3, the structure of slip Distance limiter and embodiment shown in Figure 2 are roughly the same, and difference is, this slip Distance limiter also comprises the second mounting panel 50.The second mounting panel 50 and the first mounting panel 10 be arranged in parallel, and the first pulley assembly 20 and the second pulley assembly 30 are arranged between the first mounting panel 10 and the second mounting panel 50.The second mounting panel 50 also can be made by aluminum alloy materials.
Utilize slip Distance limiter of the present utility model, the operating personnel can be limited to the distance of upper lower wire in the predetermined scope when the operation double bundle conductor.When the operation personnel moved along double bundle conductor, it is mobile together that it can drive this slip Distance limiter with hand or other traction means.Like this, by means of the slip Distance limiter, can be so that near the upper lower wire of the double bundle conductor the operating personnel can not divide too far away.This is very beneficial for the operating personnel and carries out such as collecting the operations such as stockbridge damper.
