Description
One, technical field
The invention belongs to a kind of elastic compound pull-rod that relates in the frame for movement design field
Two, background technology
Some large-scale expensive equipment equipment, for example astronomical telescope, large photoelectric theodolite, large-scale optical stabilization platform, high-precision optical rose engine etc.When dispatching from the factory, need transport applying unit to, in transportation because road surface, road conditions are complicated and changeable, when snub occurring, may occur instrument and equipment front and back, left and rightly wave, vibrate.For the safety of instrument and equipment, to fix instrument and equipment, make them fixed with car body as much as possible.Fixed form should have vibrationproof, vibration damping, shock proof usefulness.Conventional fixed form is: fix with nylon rope or the steel wire rope mode that bundlees or tiltedly draw, in order to make the tension of nylon rope or steel wire rope, usually adopt some special-purpose instrument tension.
The prior art the most approaching with the present invention is the stringing pull bar of Changchun Institute of Optics, Fine Mechanics and Physics, CAS's exploitation.As shown in Figure 1: comprise that steel wire rope 1, split pin 2, pivot pin 3, right handed screw ears 4, dextrorotation are equipped with cap 5, right handed screw 6, turnbuckle 7, left-handed screw 8, left-handed cap 9, left-handed screw ears 10, bearing pin 11, split pin 12, the car body 13 of being equipped with.
Right handed screw ears 4 by bearing pin 3 and split pin 2, connect with steel wire rope 1; Left-handed screw ears 10 connect with car body 13 by bearing pin 11, split pin 12; Right handed screw 6 and dextrorotation are equipped with cap 5, and both are threaded engagement; Left-handed screw 8 is equipped with cap 9 both is threaded engagement with left-handed; The left end of turnbuckle 7 and left-handed screw 8 are threaded engagement, and the right-hand member of turnbuckle 7 and right handed screw 6 are threaded engagement; Turnbuckle 7 is left-handed screw 8 and right handed screw 6 coaxial linking up, the pretightning force that can regulate steel wire rope 1 by swivel tightener 7.
The major defect that this stringing pull bar exists is: elasticity is little; In the transportation, because road conditions are complicated and changeable, the elasticity of adding steel wire rope is little, and instrument and equipment occurs waves, vibrate, impact etc. can make the steel wire rope of retainer instrument equipment loosening, and the safety of instrument and equipment in transportation does not guarantee.In case meet accident instrument and equipment is damaged, influences result of use, can make instrument and equipment lose use value when situation is serious.
Three, summary of the invention
In order to overcome the defective that prior art exists, the objective of the invention is to make instrument and equipment and car body to reinforce, be connected and fixed and do not take place to become flexible, guarantee the safety of instrument and equipment in transportation, a kind of elastic compound pull-rod of ad hoc meter.
The technical problem to be solved in the present invention is: a kind of elastic compound pull-rod that is used for transportation retainer instrument equipment is provided.The technical scheme of technical solution problem is made up of stringing pull bar and elastic draw bar as shown in Figure 2.The stringing pull bar comprises that steel wire rope 14, first split pin 15, first bearing pin 16, right handed screw ears 17, dextrorotation are equipped with cap 18, right handed screw 19, turnbuckle 20, left-handed screw 21, left-handed cap 22, left-handed screw ears 23, second bearing pin 24, second split pin 25 fully.
Elastic draw bar comprises screw rod monaural 26, spring 27, sleeve 28, plain cushion 29, spring washer 30, nut 31, screw rod 32, socket cover 33, socket cover ears 34, the 3rd bearing pin 35, the 3rd split pin 36, car body 37.
In this elastic compound pull-rod, right handed screw ears 17 and right handed screw 19 are integral pieces; Left-handed screw 21 and left-handed screw ears 23 also are integral pieces.Right handed screw ears 17 connect with steel wire rope 14 by first bearing pin 16 and first split pin 15; The dextrorotation that is contained on the right handed screw 19 is equipped with the side of cap 18 near right handed screw ears 17, and is threaded engagement between the right handed screw 19; Be contained in the left-handed side that is equipped with cap 22 near left-handed screw ears 23 on the left-handed screw 21, and be threaded engagement between the left-handed screw 21; The left end of turnbuckle 20 is a threaded engagement between left-handed right side that is equipped with cap 22 and left-handed screw 21, and it is threaded engagement that the right-hand member of turnbuckle is equipped with between the left side of cap 18 and the right handed screw 19 in dextrorotation; Turnbuckle 20 is right handed screw 19 and left-handed screw 21 coaxial linking up, and both keep certain spacing to make left-handed screw 21 and right handed screw 19.The left-handed screw ears 23 of stringing pull bar connect by second bearing pin 24, second split pin 25 with screw rod monaural 26 in the elastic draw bar; In elastic draw bar, screw rod monaural 26 and screw rod 32 are integral pieces; Socket cover 33 and socket cover ears 34 are integral pieces; Sleeve 28 is contained on the screw rod 32 by the borehole jack of its bottom, the bottom of sleeve 28 leans against on the left interstation of screw rod ears 26, on the screw rod 32 in sleeve 28 spring 27 is housed, the right-hand member of spring 27 contacts with sleeve 28 bottom inside, and left end contacts with plain cushion 29 on being sleeved on screw rod 32; In plain cushion 29 left sides, spring washer 30 and nut 31 also are housed on the screw rod 32 successively, nut 31 is threaded engagement with screw rod 32; Turning nut 31 compresses spring washer 30, plain cushion 29; Being sleeved between socket cover 33 on the sleeve 28 and the sleeve 28 is threaded engagement, and elastic draw bar connects with car body 37 by its socket cover ears 34, the 3rd bearing pin 35, the 3rd split pin 36.
The operation principle explanation: an end of elastic compound pull-rod connects with cooperating with car body of bearing pin, split pin by the socket cover ears of elastic draw bar, right handed screw ears and the bearing pin of the other end by the stringing pull bar, the cooperation of split pin connect with steel wire rope and fix instrument and equipment.Can strain the steel wire rope of retainer instrument equipment by the turnbuckle of regulating on the stringing pull bar.Because the elasticity of elastic draw bar is very big, can regulate pull of steel wire and pretightning force, even waving of vibration, impact and instrument and equipment occur in transportation, steel wire rope can not become flexible yet, thereby has guaranteed the safety of instrument and equipment.
Good effect of the present invention: can the be strained and fixed steel wire rope of instrument and equipment of the stringing pull bar of this elastic compound pull-rod, elastic draw bar has very big elasticity again, both combine closely, and can regulate the suffered pulling force of steel wire rope, pretightning force, alleviate the impulsive force that occurs in the transportation; Even waving of vibration, impact, instrument and equipment occur in transportation, the steel wire rope of retainer instrument equipment can not become flexible yet, and has guaranteed the safety of instrument and equipment.
