Abstract
The utility model provides a clamping spring replacing tool for a GW16 type isolation switch. The clamping spring replacing tool comprises a fixing plate, a concave baffle plate, a limit nut, a rotary screw, a spring compression cylinder and a connecting screw. The limit nut and the concave baffle plate are fixedly disposed at two ends of the fixing plate, the rotary screw is in a threaded-connection relationship with the limit nut, and the rotary screw and the spring compression cylinder are stably connected via the connecting screw. A spring is compressed by means of a force applied by the rotary screw, so the clamping spring can be replaced by one person; moreover, maintenance progress can be speeded up, and maintenance is convenient and easy to operate; and the clamping spring replacing tool has the advantages of simple structure, practical functions and good industrial popularization.
Description
Technical field
The utility model relates to a kind of GW16 type isolating switch fastening spring and changes instrument.
Background technology
GW16 disconnecting link is widely used in 220kV, 110kV place.In daily disconnecting link maintenance work, the fastening spring of conducting rod on GW16 type disconnecting link, because the reaction force of spring force is larger, is difficult to change.On GW16 disconnecting link, the fastening spring of conducting rod is fixing by pad, fixing hole and pin.In the process of mounting spring, due to the effect of spring force, be often difficult to spring to be pressed down to the position at fixing hole place, thereby iron pin cannot be installed.The reaction force of spring is huge, if single free-hand dead spring refills iron pin, this is by the work that is part consumption strength, time-consuming, and this will drag the progress of slow service work greatly.Therefore, if we can develop GW16 disconnecting link fastening spring, change specific purpose tool, our operating efficiency will improve greatly, also to service work, bring convenience.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of GW16 type isolating switch fastening spring and changes instrument, and its power by metal splint fixes, Compress Spring, simple in structure, and consumption power is little, consuming time few.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
GW16 type isolating switch fastening spring is changed an instrument, it is characterized in that: comprise fixed head, spill baffle plate, stop nut, rotary screw, spring-compressed cylinder and connecting screw rod; Described stop nut and spill baffle plate are fixedly installed on the two ends of described fixed head, and described rotary screw is threaded with described stop nut; Described connecting screw rod is connected described rotary screw and described spring-compressed cylinder are stable.
Described connecting screw rod middle part is drilled with connecting hole, and the end of rotary screw passes described connecting hole and fixes with pin; Described spring-compressed cylinder end is drilled with two through holes, and described connecting screw rod is horizontally through two through holes on spring-compressed cylinder and is connected with spring-compressed cylinder is stable.
Also include a padded plate, described padded plate is fixedly installed on the middle part of fixed head.Padded plate can be padded by upper conducting rod, makes it highly just reach the height of spring-compressed cylinder.
Described rotary screw end is provided with rotating handles.
Compared with prior art, the beneficial effects of the utility model are: by carrying out Compress Spring by the rotary screw application of force, can realize single replacing fastening spring; In addition, can accelerate repair schedule, make service work facilitate easy operating; The utility model is simple in structure, and practical function has good industry generalization.

Fig. 2 is end view of the present utility model;
Fig. 3 is vertical view of the present utility model.
In figure: 1-fixed head; 2-spill baffle plate; 3-stop nut; 4-rotary screw; 5-spring-compressed cylinder; 6-connecting screw rod; 7-rotating handles; The padded plate of 8-.
Embodiment
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing and embodiment, the utility model is described further.
Fig. 1-3 are preferred embodiment of the present utility model: a kind of GW16 type isolating switch fastening spring is changed instrument, comprises fixed head 1, spill baffle plate 2, stop nut 3, rotary screw 4, spring-compressed cylinder 5, connecting screw rod 6, rotating handles 7 and padded plate 8; Described stop nut 3 is screwed the one end that is arranged on fixed head 1, and described spill baffle plate 2 is welded on the other end of fixed head 1; Described rotary screw 4 is threaded with described stop nut 3;
Described connecting screw rod 6 middle parts are drilled with connecting hole, and the end of rotary screw 4 passes described connecting hole and fixes with pin; Described spring-compressed cylinder 5 ends are drilled with two through holes, and described connecting screw rod 6 is horizontally through two through holes on spring-compressed cylinder 5 and is connected with spring-compressed cylinder 5 is stable.Spring-compressed cylinder 5 can swing around the junction of itself and connecting screw rod 6, when wanting Compress Spring, spring-compressed cylinder is put to 5 and to the position that is straight line with fixed head 1, carry out subsequent operation again.
Described padded plate 8 is fixedly installed on the middle part of fixed head 1.Padded plate 8 can be padded by upper conducting rod, makes it highly just reach the height of spring-compressed cylinder 5.
Using method: upper conducting rod is lain on fixed head, the lower end of upper conducting rod is fixed on the spill baffle plate place of fixed head, upper end is fixed on spring-compressed cylinder place, and spring-compressed cylinder withstands fastening spring upper end (now spring-compressed cylinder has swung to the position that is straight line with fixed head); Rotary screw fixes by connecting screw rod and spring-compressed cylinder, this time, isolating switch fastening spring and rotary screw, spring-compressed cylinder, fixed head were on same straight line, can be by rotating the rotating handles of rotary screw, increase the inlet of rotary screw in stop nut, give the spring-compressed cylinder application of force, thereby reach the effect of Compress Spring, when spring-compressed is to pin hole place, just steady pin can be installed.In addition, the connected mode of spring-compressed cylinder and connecting screw rod, the tie point that spring-compressed cylinder can be realized around itself and connecting screw rod swings.
The above embodiment has only expressed Some Species execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
