Abstract
A kind of jack of the utility model forces down tools, comprising: two semicircle snap rings (2), tie bolt (3), boosting-rod (6) and lugs (7); Two semicircle snap rings (2) are combined and are stuck on jack base (1), two semicircle snap rings (2) are screwed together by lug (7), tie bolt (3) is screwed onto jack lock sleeve (4) from jack lock sleeve (4) side, boosting-rod (6) is spirally connected from jack lock sleeve (4) opposite side or is plugged on jack lock sleeve (4), rotating boosting-rod (6) drives jack lock sleeve (4) to rotate, and mandril of lifting jack (5) moves downward.Coordinated with jack lock sleeve (4) by semicircle snap ring (2), and use boosting-rod (6) to apply external force, make jack lock sleeve (4) forced rotating drive mandril of lifting jack (5) to move down, thus the pressure completing jack is put down.
Description
Technical field
The invention relates to a kind of instrument putting down jack, particularly relates to a kind of instrument for putting down jack by force.
Background technology
The outdoor jack parked is subject to the impact of temperature and sleet, easily occurs situation that is icing and corrosion, causes jack clamping stagnation, jeopardize aircraft safety.At present, there is no jack and force down tools, convention resolution method uses external force repeatedly to knock jack, makes it loosen by the method for vibration.The deficiency that this method exists: waste time and energy, if staff lacks experience, knocks for a long time on rare occasion and jack can not be made to loosen.
Summary of the invention
The object of the invention is: the object of this invention is to provide a kind of jack and force down tools, can reduce jack and force to put down work difficulty, pressure when realizing jack clamping stagnation is put down.
Technical scheme of the present invention is: a kind of jack forces down tools, comprising:
Two semicircle snap rings 2, tie bolt 3, boosting-rod 6 and lugs 7;
Two semicircle snap rings are 2-in-1 to be stuck on jack base 1 together, two semicircle snap rings 2 are screwed together by lug 7, tie bolt 3 is screwed onto jack lock sleeve 4 from jack lock sleeve 4 side, boosting-rod 6 is spirally connected from jack lock sleeve 4 opposite side or is plugged on jack lock sleeve 4, rotating boosting-rod 6 drives jack lock sleeve 4 to rotate, and mandril of lifting jack 5 moves downward.
The advantage of the invention is: coordinated with jack lock sleeve 4 by semicircle snap ring 2, and uses boosting-rod 6 to apply external force, jack lock sleeve semi-finals row is rotated and drives mandril of lifting jack 5 to move down, thus the pressure completing jack is put down.This invention instead of traditional percussion vibration and makes its method loosened, and greatly reduces the requirement that this works for personnel ability and experience, greatly improves work efficiency, decrease work-hours.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of jack of the utility model forces down tools.
Detailed description of the invention
Below the utility model is described in further details.
A kind of jack of the utility model forces down tools, as shown in Figure 1, comprising:
Two semicircle snap rings 2, tie bolt 3, boosting-rod 6 and lugs 7;
Two semicircle snap rings are 2-in-1 to be stuck on jack base 1 together, two semicircle snap rings 2 are screwed together by lug 7, tie bolt 3 is screwed onto jack lock sleeve 4 from jack lock sleeve 4 side, boosting-rod 6 is spirally connected from jack lock sleeve 4 opposite side or is plugged on jack lock sleeve 4, rotating boosting-rod 6 drives jack lock sleeve 4 to rotate, and mandril of lifting jack 5 moves downward.
In Fig. 1, mandril of lifting jack 5 and jack lock sleeve 4 are threaded connection.Semicircle snap ring 2 is connected as a single entity by tie bolt 3 and jack lock sleeve 4, semicircle snap ring 2 is connected with convex surface by inner groove with jack base 1 simultaneously, the two is made to relatively rotate, but jack lock sleeve 4 can not up-and-down movement, when use boosting-rod 6 is connected on jack lock sleeve 4, and during turn-back semicircle snap ring 2, jack lock sleeve 4 rotates thereupon, but it is constant highly all the time, owing to mandril of lifting jack 5 there being the screw thread coordinated with jack lock sleeve 4, mandril of lifting jack 5 just moves downward under the pull effect of jack lock sleeve 4, the pressure achieving jack is put down.
