Abstract
The utility model discloses a measuring device for detecting the inserting depth of the contact of a cart and is characterized in that the measuring device comprises a measuring bar installed in a contact arm and an insulating barrier installed in the contact, one end of the measuring bar is fixedly connected with the insulating barrier, the insulating barrier can move in the contact, and when the insulating barrier moves in the contact, the other end of the measuring bar can stretch out of the panel of the cart and the length of the measuring bar stretching out of the panel of the cart is equal to the moving distance of the insulating barrier in the contact. By adopting the device, whether a primary contact is normally inserted or not can be judged accurately and intuitively, and thereby serious heat accidents on equipment caused by the poor contact of the primary contact can be avoided.
Description
Technical field
The utility model relates to a kind of measurement mechanism, particularly a kind of contact insertion depth measurement mechanism of checking dolly.
Background technology
When the inspection dolly of existing 10kV indoor metal armoring draw out switchgear inserts inspection at one-time contact, only rely on operating personnel to estimate, can not differentiate the degree of depth that one-time contact inserts exactly, judge by accident easily, cause inserting the insufficient seriously heating accident of equipment that causes of contact because of one-time contact.For this reason, the applicant has developed a kind of contact insertion depth measurement mechanism of checking dolly, the inspection dolly that can prevent the 10kV indoor metal armoring draw out switchgear by this measurement mechanism is judged by accident when one-time contact inserts inspection, contacts insufficient and seriously heating accident of equipment that cause to avoid one-time contact to insert.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of contact insertion depth measurement mechanism of checking dolly, the inspection dolly that can prevent the 10kV indoor metal armoring draw out switchgear by this measurement mechanism is judged by accident when one-time contact inserts inspection, contacts insufficient and seriously heating accident of equipment that cause to avoid one-time contact to insert.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of contact insertion depth measurement mechanism of checking dolly, it is characterized in that it comprises is installed in the sounding rod in the contact arm and is installed in insulation barrier in the contact, one end of sounding rod is fixedlyed connected with insulation barrier, this insulation barrier can move in contact, when insulation barrier is mobile in contact, the other end of sounding rod may extend to outside the dolly panel, and the length that sounding rod extends to outside the dolly panel is identical in the distance that contact moves with insulation barrier.
As the utility model improvement of the technical scheme, be set with back-moving spring on the described sounding rod, be set with backboard on the described sounding rod that is positioned at contact, an end of described back-moving spring is resisted against on the insulation barrier, and the other end is resisted against on the backboard.
As the utility model further improvement in the technical proposal, described sounding rod is provided with the length scale.
The beneficial effects of the utility model are: check that dolly is after increasing this measurement mechanism, whether normally the length that can extend to by sounding rod after the inspection dolly is pushed into the working position outside the dolly panel differentiate one-time contact insertion contact accurately, intuitively, thereby prevent that one-time contact is because of seriously heating accident of loose contact generation equipment; And because sounding rod is provided with the length scale, check that dolly is after propelling, the insulating bar of band scale stretches out checks the dolly panel, by the scale on the insulating bar extension of band scale, can read the degree of depth that one-time contact inserts exactly, thereby prevent the degree of depth that the erroneous judgement one-time contact inserts, guarantee that one-time contact inserts fully contact.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of checking dolly;
Fig. 2 be Fig. 1 band broken section left view;
Fig. 3 is a structural representation of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 1, Fig. 2, Fig. 3 are the structural representation of a kind of preferred implementation of the utility model.The contact insertion depth measurement mechanism of the inspection dolly in embodiment as shown in the figure, comprise and be installed in the sounding rod 2 in the contact arm 1 and be installed in insulation barrier 4 in the contact 3, wherein, one end of sounding rod 2 is fixedlyed connected with insulation barrier 4, on sounding rod 2, be set with back-moving spring 5, be set with backboard 6 on the sounding rod 2 that is positioned at contact 3, an end of back-moving spring 5 is resisted against on the insulation barrier 4, and the other end is resisted against on the backboard 6.
This retaining that insulate, 4 can move in contact, and when insulation barrier 4 was mobile in contact, the other end of sounding rod 2 may extend to outside the dolly panel, and the length that sounding rod 2 extends to outside the dolly panel is identical in the distance that contact 3 moves with insulation barrier 4.
After checking that dolly pushes the working position, check contact and the interior contacts mates of switchgear on the dolly, insulation barrier is subjected to move in the contact of roof pressure on the detection dolly of contact in the switchgear, one end of sounding rod is extended to outside the panel of checking dolly, extend to the outer length of dolly panel by the observation sounding rod and differentiate whether normally insertion contact of one-time contact accurately, intuitively, thereby prevent that one-time contact is because of seriously heating accident of loose contact generation equipment.
As the utility model another preferred embodiment, sounding rod is provided with length scale (not shown), check that dolly is after propelling, the insulating bar of band scale stretches out checks the dolly panel, by the scale on the insulating bar extension of observation band scale, can read the degree of depth that one-time contact inserts exactly, thereby prevent the degree of depth that the erroneous judgement one-time contact inserts, guarantee that one-time contact inserts fully contact.
The above only is preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it.So long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
