Abstract
The utility designs a dismantling assistor of a forcipate screw cap which mainly consists of the main body of the forcipate assistor, a main mandril, a hypo-mandril and a solid wrench. At the operating time, the solid wrench is arranged on the screw cap. A hand grip is adjusted. The two solid grips are kept at a balanced state to the best possibility. Then the hypo-mandril is adjusted to the state that the convex heads of the hypo-mandril match gets tightly with the suited grooves at the two ends of the head of the forcipate assistor. When one hand holds the main body of the assistor and the other hand holds a general wrench to lock the quartet-head in the middle of the main mandril, the main mandril is moved and the convex heads is made to get tightly with the grooves at the end of the forcipate assistor. At the same time, the hypo-mandril extends to the two sides by the force that the main body of the forcipate assistor bears. Then after the screw cap is turned, the aim of dismanting the screw cap is achieved. The utility has the advantages of simple structure, easy use, no electricity use, energy save, no environmental condition restrictions, long life, great energy, low cost, no noise pollution, safety and reliability and is applied for dismantiling work of screw cap for medium and large equipments.
Description
One, technical field
The utility model relate to a kind of in, main equipment dismounting nut instrument, particularly a kind of pincerlike nut dismounting assistor.
Two, background technology
At present commercially available and on-the-spot use most be manual, electronic and pneumatic in, the instrument of main equipment usefulness dismounting nut, its common drawback is:
1, as some small-sized above-mentioned dismounting nut instrument, though easy to use, dynamics is not enough, uses effort, the afterburning rod of the employing that has plays leverage, but afterburning rod can not arbitrarily extend, so dynamics is not strong yet, beat with the reinforcing of big Hammer head in addition, more dangerous.
2, use electronic or pneumatic tools carry out the nut dismounting, need electricity consumption not only dangerous, but also make the lead damage easily, cause the accident of human electric shock, use electronic, pneumatic tools because vibration force and impulsive force are bigger in addition, using is that inconvenience is dangerous again.
3, electronic, pneumatic tools must use in the place that power supply is arranged, and are subjected to the restriction of environment and condition, so also inconvenient.
4, use electronic, pneumatic tools because its structure is comparatively complicated, in addition sometimes will with the supporting use of compressor, so cost is higher, should not promote.
No matter 5 is electronic or its noise of pneumatic tools is all bigger, especially in the construction of resident's concentration zones, easier site operation personnel and resident are worked the mischief, be unfavorable for environmental protection.
6, electronic, pneumatic tools damage easily, and in case trouble is keeped in repair also in damage, the influence use is the delay duration also.
Three, summary of the invention
At at present, particularly centering, the existing defective of employed electronic, the pneumatic nut dismantling device of main equipment, a kind of pincerlike nut dismounting assistor of ad hoc meter, this assistor mainly is made up of pincerlike assistor main body, main push rod, inferior push rod and special-shaped stiff hand, the afterbody that screwed end of wherein main push rod and pincerlike assistor main body have internal thread flexibly connects, and its other end has semicircular plush copper, is inserted in the groove that pincerlike assistor main body afterbody is complementary with it; In addition, the end that twice push rods have plush copper is inserted in the groove that pincerlike assistor body head two ends are complementary with it, and its screwed other end is connected with the flexible connection head of special-shaped stiff hand.
During operation, earlier with stiff gloves on by the nut of dismounting, adjust the handle of stiff hand then, make two stiff handles be in parastate as far as possible, screw thread on two on the pincerlike assistor body head inferior push rods is regulated, made its plush copper hold out against the groove at pincerlike assistor head two ends; Hold pincerlike assistor main body with one in addition, use general spanner to block the middle square head of main push rod with the another hand, pull main push rod, the plush copper of main push rod is withstood the groove of pincerlike assistor main body afterbody, its top power be about that hand exerts oneself more than 3 times, at this moment time push rod also is subjected to the active force of pincerlike assistor main body simultaneously and stretches to both sides, the top power that the top power of inferior push rod of this moment is about suffered pincerlike assistor main body is more than 3 times, thereby makes the purpose that is reached the dismounting nut by the rotation of the nut of dismounting with this power.
Four, caption
The utility model accompanying drawing is pincerlike dismounting nut assistor structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, the utility model is by pincerlike assistor main body (1), main push rod (2), inferior push rod (3) and special-shaped stiff hand (4) are formed, the afterbody that screwed end of wherein main push rod (2) and pincerlike assistor main body (1) have internal thread (10) flexibly connects, its other end has in the groove (5) that semicircular plush copper is inserted in pincerlike assistor main body (1) afterbody, the end that twice push rods (3) have plush copper is inserted in the groove (6) that pincerlike assistor main body (1) head two ends are complementary with it, and its screwed other end is connected with the flexible connection head (7) of special-shaped stiff hand (4).During operation, earlier with stiff gloves on by the nut of dismounting, adjust the handle (9) of stiff hand then, make two stiff handles (9) be in parastate as far as possible, screw thread on two on pincerlike assistor main body (1) the head inferior push rods (3) is regulated, made its plush copper hold out against the groove (6) at pincerlike assistor head two ends; Hold pincerlike assistor main body (1) with one in addition, use general spanner to block the middle square head (8) of main push rod (2) with the another hand, pull main push rod (2), the plush copper of main push rod (2) is withstood the groove (5) of pincerlike assistor main body (1) afterbody, its top power be about that hand exerts oneself more than 3 times, at this moment time push rod (3) also is subjected to the active force of pincerlike assistor main body (1) simultaneously and stretches to both sides, the top power that the top power of inferior push rod (3) of this moment is about suffered pincerlike assistor main body (1) is more than 3 times, thereby makes the purpose that is reached the dismounting nut by the rotation of the nut of dismounting with this power.
