Embodiment
Be described in detail to according to preferred embodiment of the present utility model below with reference to accompanying drawing.By accompanying drawing and corresponding explanatory note, it will be understood to those of skill in the art that characteristics and advantages of the present utility model.
As shown in Fig. 1 (a), (b) to Fig. 3, the cable chamber door 1 of the cable vault of middle pressure ring main unit is pull-type.Cable vault's framework arranges hook 1-1, when opening cable chamber door 1, first cable chamber door 1 up being promoted certain height, then taking out cable chamber door 1 outward.
Fig. 4 illustrates the cable chamber door interlocking gear according to an embodiment of the present utility model, and for the sake of clarity, wherein mechanism's front end panel has been removed.Cable chamber door interlocking gear shown in Figure 4 comprises catch 2 and catch actuating mechanism 3.
Described catch actuating mechanism 3 can be configured to multi-connecting-rod mechanism.
In Figure 5, when upwards cable chamber door 1 is opened in lifting (as shown in hollow arrow), described cable chamber door 1 activates described catch actuating mechanism 3, and then described catch actuating mechanism 3 moves described catch 2 (see Fig. 4), thus described catch 2 is made to move to the latched position blocking the ground connection handle hole 10 be arranged on described cable chamber door interlocking gear.
Specifically, still as shown in Figure 4, described multi-connecting-rod mechanism comprise be arranged on described cable chamber door interlocking gear rear bearing sheet 12 on and the chain pull bar 4 together of being linked in sequence, chain bull stick 5, brake spool 6, brake cable 7, back-moving spring 8 and reset bull stick 9.
One end of described chain pull bar 4 is connected with described chain bull stick 5 (such as adopting pin-groove to be slidably connected), when opening described cable chamber door 1, described cable chamber door 1 activates the other end of described chain pull bar 4, thus drives the rotation (as shown in curved arrow) of described chain bull stick 5.
Now, the rotation of described chain bull stick 5 causes loose (as shown in the solid linear pattern arrow) of the described brake cable 7 supported by described brake spool 6, and one end of described brake cable 7 is connected with described chain bull stick 5.
One end of described reset bull stick 9 is connected with the other end of described brake cable 7, the other end of described reset bull stick 9 is connected with described catch 2 (such as adopt pin-groove is slidably connected, gear connection etc.), and described back-moving spring 8 is between the two ends of described reset bull stick 9 and elastic force acts on described reset bull stick 9.
As shown in Figure 6, when opening described cable chamber door 1, loose due to described brake cable 7, described reset bull stick 9 can rotate (as shown in curved arrow) under the elastic force effect of described back-moving spring 8.Described reset bull stick 9 this rotates through the other end of described reset bull stick 9 and the connection of described catch 2 thus mobile described catch 2 (as shown in hollow arrow), when described catch 2 be moved to block described ground connection handle hole 10 time, described reset bull stick 9 is in its dead-centre position.
As shown in Figure 8, described reset bull stick 9 is in its dead-centre position under the effect of back-moving spring.Even if at this moment catch 2 promotes (as shown in hollow arrow) by external force, can not move, namely operating personnel can not push catch 2 aside, prevent from carrying out misoperation.
At Fig. 7, the cable chamber door interlocking gear with mechanism's front end panel 11 is shown, in the described latched position of described catch 2, through described ground connection handle hole 10 (same through the respective through hole on mechanism's front end panel), the external force be applied on described catch 2 also cannot move described catch 2.
As shown in Figure 9, when closing cable chamber door 1, cable chamber door 1 sinks (as shown in hollow arrow) under gravity automatically, described chain pull bar 4 is driven and moves downward, described cable chamber door 1 activates described catch actuating mechanism 3, and then described catch actuating mechanism 3 moves described catch 2 (see Figure 10), thus described catch 2 is made to move to the non-locked position that can not block the ground connection handle hole 10 be arranged on described cable chamber door interlocking gear.
Specifically, as shown in Figure 10, when closing described cable chamber door 1, described cable chamber door activates the other end of described chain pull bar 4, thus drives the rotation (as shown in curved arrow) of described chain bull stick 5.
Now, the rotation of described chain bull stick 5 causes the tension of the described brake cable 7 supported by described brake spool 6 (as shown in solid linear pattern arrow).Due to the tension of described brake cable 7, the elastic force effect that described reset bull stick 9 overcomes described back-moving spring 8 is rotated.
And then, the rotation (as shown in curved arrow) of described reset bull stick 9 by as described in reset bull stick 9 the other end and as described in catch 2 connection thus mobile as described in catch 2 (as shown in hollow arrow), described reset bull stick 9 rotates through its dead-centre position, and described catch 2 is moved to the position can not blocking described ground connection handle hole 10.
Figure 11 illustrates the front elevation according to cable chamber door interlocking gear of the present utility model with mechanism's front end panel, wherein on the non-locked position of described catch 2, ground connection handle hole 10 is abdicated (same respective through hole of passing on mechanism's front end panel is also abdicated).
The cable chamber door interlocking gear provided based on said structure makes after cable chamber door is opened, and ground connection handle hole is plugged, and can not be pushed aside by external force, cannot carry out ground connection sub-switching operation, ensure that the life security of repair and maintenance personnel.And after cable chamber door is closed, ground connection handle hole 10 is abdicated, operating personnel can carry out ground connection sub-switching operation.
With reference to specific embodiment, although the utility model is illustrated in the specification and illustrated in the drawings, but be to be understood that, when not departing from the utility model scope defined in claim, art personnel can make multiple change and alternative method step, the detection means wherein of multiple equivalent.And, the combination of the technical characteristic herein between specific embodiment, element and/or function and collocation are clear distinct, therefore according to the content disclosed in these, art personnel can understand technical characteristic, element and/or function in embodiment and method step can optionally be incorporated in another specific embodiment, unless foregoing has other description.In addition, according to instruction of the present utility model, do not departing from the scope of the utility model essence, adapting to special situation and can make many changes.Therefore, the utility model is not limited to accompanying drawing institute graphic other specific embodiment, and the specific embodiment as the preferred forms at present contemplated by enforcement the utility model described in specification, and the utility model intention comprises all execution modes fallen in above-mentioned specification and appended right.
