Abstract
The utility model discloses hydraulic valve bank plug-in unit extracting tool, it comprises handle (1), and handle (1) one end connects distinguish expansion set bolt (3) by screwed hole (2); Distinguish expansion set bolt (3) is provided with distinguish expansion set clamping nut (4), distinguish expansion set clamping nut (4) right side is connected with distinguish expansion set support member (5), and distinguish expansion set support member (5) right side is provided with distinguish expansion set (6).The utility model, by rotating distinguish expansion set clamping nut, makes distinguish expansion set support member move along distinguish expansion set bolt to boss side; By domatic and boss, distinguish expansion set is outwards expanded, then complete dismounting by pulling out handle, improve removal efficiency.Be pulled through outside in journey, due to the employing of distinguish expansion set is brass workpiece, and hardness is lower, and two ends, outer ring are equipped with fillet, can avoid scraping damage.The utility model can not only improve removal efficiency, can also prevent plug-in unit scraping damage, has safe and reliable advantage.
Description
Technical field
The utility model relates to a kind of extracting tool of hydraulic valve bank plug-in unit, especially for the specific purpose tool of hydraulic valve bank plug-in unit in dismounting power station.
Background technology
In power station during the dismounting of hydraulic valve bank plug-in unit, use the instrument of existing routine to dismantle valve group plug-in unit from valve seat more difficult, removal efficiency is low; And when dismantling, the metallic sealing section on plug-in unit is easily by instrument scraping damage, and affect the sealing effectiveness of plug-in unit, security is undesirable.Therefore, it is low that existing hydraulic valve bank plug-in unit extracting tool also exists removal efficiency, easier scraping damage plug-in unit and the undesirable problem of security.
Utility model content
The purpose of this utility model is, provides a kind of hydraulic valve bank plug-in unit extracting tool.The utility model can not only improve removal efficiency, can also prevent plug-in unit scraping damage, has safe and reliable advantage.
The technical solution of the utility model: hydraulic valve bank plug-in unit extracting tool, comprises handle, handle one end connects distinguish expansion set bolt by screwed hole; Distinguish expansion set bolt is provided with distinguish expansion set clamping nut, on the right side of distinguish expansion set clamping nut, is connected with distinguish expansion set support member, on the right side of distinguish expansion set support member, be provided with distinguish expansion set.
In aforesaid hydraulic valve bank plug-in unit extracting tool, described distinguish expansion set bolt one end is provided with round table-like boss, and one end of distinguish expansion set support member is provided with domatic.
In aforesaid hydraulic valve bank plug-in unit extracting tool, described distinguish expansion set is brass workpiece and is provided with two, and the two ends of distinguish expansion set inner ring are equipped with domatic, and the two ends, outer ring of distinguish expansion set are equipped with fillet.
Compared with prior art, the utility model improves hydraulic valve bank plug-in unit extracting tool, by rotating distinguish expansion set clamping nut, distinguish expansion set support member is moved to boss side along distinguish expansion set bolt; By domatic and boss, distinguish expansion set is outwards expanded, then complete dismounting by pulling out handle, improve removal efficiency.Be pulled through outside in journey, due to the employing of distinguish expansion set is brass workpiece, and hardness is lower, and two ends, outer ring are equipped with fillet, can avoid scraping damage.Therefore, the utility model can not only improve removal efficiency, can also prevent plug-in unit scraping damage, has safe and reliable advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is utility model works schematic diagram.
Being labeled as in accompanying drawing: 1-shakes hands, 2-screwed hole, 3-distinguish expansion set bolt, 4-distinguish expansion set clamping nut, 5-distinguish expansion set support member, 6-distinguish expansion set, and 7-boss, 8-is domatic, 9-plug-in unit, 10-hydraulic valve bank.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.Hydraulic valve bank plug-in unit extracting tool, form as shown in Figure 1, comprise handle 1,1 one end of shaking hands connects distinguish expansion set bolt 3 by screwed hole 2; Distinguish expansion set bolt 3 is provided with distinguish expansion set clamping nut 4, on the right side of distinguish expansion set clamping nut 4, is connected with distinguish expansion set support member 5, on the right side of distinguish expansion set support member 5, be provided with distinguish expansion set 6.
Described distinguish expansion set bolt 3 one end is provided with round table-like boss 7, and one end of distinguish expansion set support member 5 is provided with domatic 8; Described distinguish expansion set 6 is brass workpiece and is provided with two, and the two ends of distinguish expansion set 6 inner ring are equipped with domatic 8, and the two ends, outer ring of distinguish expansion set 6 are provided with fillet.
The utility model is a kind of knockdown instrument, first handle 1, distinguish expansion set bolt 3, distinguish expansion set clamping nut 4, distinguish expansion set support member 5 and distinguish expansion set 6 is combined by shown in Fig. 1 during use, and wherein distinguish expansion set 6 first keeps the state that do not stress; Then as shown in Figure 2, put into plug-in unit 9 together, tighten distinguish expansion set clamping nut 4 again, distinguish expansion set support member 5 is moved along direction shown in Fig. 2, distinguish expansion set 6 is extruded by distinguish expansion set support member 5 and distinguish expansion set bolt 3 lug bosses at end part 7, domatic 8 and the boss 7 of distinguish expansion set support member 5 one end extrudes with domatic 8 on distinguish expansion set 6, and two distinguish expansion sets 6 are outwards expanded the inwall swelling of plug-in unit 9; Opposite direction finally along direction shown in Fig. 2 pulls handle 1, just plug-in unit 9 can be extracted from hydraulic valve bank 10., be pulled through outside in journey, due to distinguish expansion set 6 employing is brass workpiece, and its hardness, well below the hardness of plug-in unit 9, can avoid the metallic sealing section scratch on plug-in unit 9 and plug-in unit 9, and two ends, outer ring is equipped with fillet, further avoid scraping damage meanwhile.
