Description
Technical field
The utility model relates to the special operating tool carrying out Maintenance and Repair in a kind of transmission line, specifically a kind of specific purpose tool installed or change fuse switch.
Background technology
Fuse is widely used in high and low voltage electric distribution system and control system and power consumption equipment, as the protector of short circuit and overcurrent, is apply one of the most general protection device.Fuse is a kind of overcurrent protective device.Fuse is primarily of melt and fusion tube and the outer part composition such as filled.At present, in the distribution transformer that China runs in a large number, high-pressure side is all provided with RW series outdoor drop-out fuse, as short circuit and the overladen protection of transformer.Because its fuse setting height(from bottom) is higher, simultaneously because needing dismounting fusion tube when repair and maintenance or a variety of causes break down.For a long time, the brake pull-rod of insulation is used to carry out during dismounting fusion tube.The top of brake pull-rod is fixedly installed the push-and-pull head for operation etc. of operating a switch.Push-and-pull head is made up of two mutually perpendicular metal tubes, and wherein a metal tube is arranged along brake pull-rod direction, and another metal tube is vertical with brake pull-rod to be arranged.Fusion tube need be suspended on the push-and-pull head place on brake pull-rod top during use, provoke erection to install by artificial or change fuse afterwards.Because brake pull-rod and fusion tube are point cantact in installing process, easily cause fusion tube to play pendulum, operating personnel are difficult to size and the balance of assurance dynamics, very easily landing break fusion tube, injure personnel by a crashing object, damage equipment.
Utility model content
The utility model technical issues that need to address are to provide simple, the easy to operate erecting tools for high-voltage drop fuse of a kind of structure.
The technical scheme that the utility model adopts is specifically:
A kind of erecting tools of high-voltage drop fuse, comprise the brake pull-rod 1 that one end is provided with push-and-pull 2, push-and-pull 2 is made up of two mutually perpendicular pipes, wherein a pipe is arranged along brake pull-rod direction, another manages arrange vertical with brake pull-rod, the upper end of described brake pull-rod 1 arranges an opening elastic caoutchouc 3, and opening elastic caoutchouc 3 is provided with two shell fragments 31 coordinated with the fusion tube of fuse, and opening elastic caoutchouc 3 is fixedly mounted on brake pull-rod 1 by connector 4.
Described shell fragment 31 comprise connect successively shell fragment outer end 311, shell fragment middle-end 312 and shell fragment the inner 313; Shell fragment outer end 311 and shell fragment inner 313 are straight plate, and shell fragment middle-end 312 is arc;
Nervous spring 35 is provided with between described two shell fragment the inners 313.
Described brake pull-rod 1 comprises multiple brake pull-rod segment 11, is threaded between adjacent brake pull-rod segment 11.
Owing to have employed technique scheme, the technological progress that the utility model obtains is:
The utility model devises the opening elastic caoutchouc and shell fragment that coordinate with the fusion tube of fuse, by the elasticity making full use of opening elastic caoutchouc during use, fuse tube is clipped between two shell fragments, decreases in operation the rocking of fuse, convenient operation, and stability and safety.Also have and use brake pull-rod segment 11 to combine, different height can be applicable to, handled easily.The utility model has simple, easy to operate, reliable, the time saving and energy saving advantage of structure, and fuse can not be caused to fall damage, avoid waste, cost-saving, more ensure that the safety of personnel and equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of brake pull-rod.
Fig. 3 is the schematic cross-section of shell fragment junction.
Embodiment
As shown in Fig. 1, an erecting tools for high-voltage drop fuse, comprises the brake pull-rod 1 that one end is provided with push-and-pull 2, and push-and-pull 2 is made up of two mutually perpendicular metal tubes, wherein a metal tube is arranged along brake pull-rod direction, and another metal tube is vertical with brake pull-rod to be arranged.The upper end of described brake pull-rod 1 arranges an opening elastic caoutchouc 3, and opening elastic caoutchouc 3 is provided with two shell fragments 31 coordinated with the fusion tube of fuse, and opening elastic caoutchouc 3 is fixedly mounted on brake pull-rod 1 by connector 4.
During use, the upper end of fuse is suspended on push-and-pull 2, outwards opened by two of opening elastic caoutchouc 3 shell fragments 31 with hand, the lower end of fuse is put between two shell fragments 31, and two shell fragments 31 clamp the lower end of fuse, install.In installation process, the two ends of fuse are all fixed, installation that can be safer.During installation, pulled downwards by this instrument, because opening elastic caoutchouc 3 has elasticity, fuse departs from from this instrument, fulfils assignment.
As shown in Figure 2, the conveniently operation of differing heights, also can be designed to multiple brake pull-rod segment 11 by brake pull-rod 1, be threaded between adjacent brake pull-rod segment 11.According to concrete height, the brake pull-rod segment 11 of choice for use varying number combines.
As shown in Figure 3, shell fragment 31 comprise connect successively shell fragment outer end 311, shell fragment middle-end 312 and shell fragment the inner 313.Shell fragment outer end 311 and shell fragment inner 313 are straight plate, and shell fragment middle-end 312 is arc.Shell fragment outer end 311 is inlet portions of fuse, and shell fragment middle-end 312 is clamping parts of fuse, and arc can make the better of clamping.In order to prevent fuse from skidding off from shell fragment outer end 311 in operation, between two shell fragment the inners 313, be provided with nervous spring 35.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for a person skilled in the art, do not departing under the utility model general idea prerequisite; can also make some changes and improvements, these also should be considered as protection range of the present utility model.
