Abstract
The utility model relates to a maintenance tool used for a converter valve assembly in a direct-current power transmission system, and discloses a remover for a thyristor in the converter valve assembly. The remover comprises a left fork stay and a right fork stay, and is characterized by also comprising a guide rod, wherein the tail of the left fork stay is fixed at the left end of the guide rod, the tail of the right fork stay passes through the guide rod in a sliding way, and a hydraulic jack is arranged on the left fork stay close to the tail.
Description
Technical field
The utility model relates to the maintenance tool that is used for converter valve components in the DC transmission system, relates in particular to the extracting tool of IGCT in a kind of converter valve components.
Background technology
Along with the fast development of DC transmission system, the maintenance of DC converter station becomes the problem that the direct current transportation industry is progressively paid close attention to.At present, when changing the IGCT in the converter valve components, used tool generally is made up of screw rod and two fork bars being arranged on the screw rod; During use, the fork bar inserts respectively in the radiator hole on IGCT both sides, and by the gear drive screw rod, one of them fork bar changes two distances between the fork bar along screw motion, can realize the dismounting of IGCT like this.But for the fork bar along screw motion, its stress point is positioned at the two ends of fork bar, therefore, during use, waste time and energy, and fork bar and screw rod easy deformation, cause tool damage.
Summary of the invention
Effort and the easy problem of damaging when using for the instrument that has solved existing replacing converter valve components IGCT, the extracting tool that the purpose of this utility model saves time when being a kind of the use is provided and requires great effort and do not allow IGCT in the flimsy converter valve components.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
The extracting tool of IGCT in a kind of converter valve components comprises left cross strip and right cross strip, it is characterized in that, also comprise guide rod, wherein the afterbody of left cross strip is fixed on the left end of guide rod, and the afterbody of right cross strip slides and is applied on the guide rod, and left cross strip is provided with hydraulic jack near afterbody.
Further improvement of the utility model and characteristics are:
The right-hand member of described guide rod is provided with screw thread and nut, and nut left side being provided with to slide and being applied in dish bullet on the guide rod, and dish bullet left side compresses right cross strip.
Be provided with cushion block between described hydraulic jack and the right cross strip.
Because power set of the present utility model are hydraulic jack, and are time saving and energy saving in the use; The position of hydraulic jack is near the left cross strip afterbody simultaneously, and the left cross strip afterbody slides again and is applied on the guide rod, and fork bar and guide rod are not yielding, can not cause tool damage; And then the right-hand member of guide rod is provided with screw thread and nut, and nut left side being provided with to slide and being applied in dish bullet on the guide rod, and dish bullet left side compresses right cross strip, and the dish resilience energy is balance right cross strip head stressed enough to a certain extent, and the distortion of fork bar and guide rod is littler.Compared with prior art, the utlity model has substantive distinguishing features and marked improvement.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the structural representation of the extracting tool of IGCT in a kind of converter valve components of the present utility model;
Fig. 2 is the structural representation of fork bar;
Among the figure: 1, left cross strip; 2, right cross strip; 3, hydraulic jack; 4, guide rod; 5, dish bullet; 6, nut; 7, cushion block.
The specific embodiment
With reference to Fig. 1, Fig. 2, the extracting tool of IGCT in a kind of converter valve components, wherein the afterbody of left cross strip 1 is fixed on the left end of guide rod 4, the afterbody of right cross strip 2 slides and is applied on the guide rod 4, the right-hand member of guide rod 4 is provided with screw thread and nut 6, nut 6 left sides are provided with to slide and are applied in dish bullet 5 on the guide rod 4, and dish bullet 5 left sides compress right cross strip 2; Left cross strip 1 is provided with hydraulic jack 3 near afterbody, is provided with cushion block 7 between hydraulic jack 3 and the right cross strip 2, uses different cushion blocks 7 can enlarge the scope of application of hydraulic jack 3, reduces the cost of hydraulic jack 3, and then reduces the cost of extracting tool.
When using the utility model to change the converter valve components IGCT, earlier with about the head of two fork bars insert and will change in the radiator special hole on IGCT both sides, select suitable cushion block 7, adjusting nut 6 is to correct position, start hydraulic jack 7 and promote left cross strip 1, the spacing of two radiators is strengthened, guide rod 4 plays the parallel effect of two fork bars of keeping at this moment, adjusting nut 6 guarantees that guide rod 4 is not out of shape by stretch bending, after disassembling IGCT, slowly discharge the pressure of hydraulic jack 3, take out extracting tool and get final product.
