Abstract
The utility model discloses a single wing falling machine comprising a vertical guide rail, a box body moving on the vertical guide rail, a chain lifting the box body, a support arm, a buffer device arranged on the box body, and a transverse rod; the transverse rod is vertically fixed on the top of the vertical guide rail; one end of the chain is fixed with the box body, and the other end of the chain is fixedly connected on the transverse rod; the support arm is fixed on the box body through a fulcrum; the buffer device comprises at least one hydraulic buffer rods. The hydraulic principle is employed to obtain buffer effect, so massive noises caused by rigid bumping is prevented, and simultaneously the buffer device is protected, thereby improving test efficiency, and prolonging the service life of the single wing falling machine.
Description
Technical field
The proving installation of drop test when the utility model relates to a kind of packed and transported, relates in particular to a kind of single-blade falling machine.
Background technology
Drop test is a wherein test of packed and transported test, utilizes single-blade falling machine to complete test, is generally applicable to the test sample plate that volume and weight is less.In test process, due to the support arm bottom rapidly, after the support arm bottom, must there be parts that it is stopped rapidly.
Single-blade falling machine of the prior art adopts rigid element and rubber blanket to cushion, stop rapidly after realizing the support arm bottom, but rubber blanket is in the continuous falling process of support arm, quite easily damages, after damaging directly and rigid element collide, noise is very large.
Utility model content
For solving existing problem in above-mentioned prior art, the utility model provides a kind of noise little, long-lived single-blade falling machine.
The utility model adopts following technical scheme to realize: a kind of single-blade falling machine, the casing that comprises upright guide rail, move on upright guide rail, promote casing chain, support arm, be arranged on snubber assembly and cross bar on casing, described cross bar is vertically fixed on described upright guide rail top, described chain one end and described casing are fixed, the other end is fixedly connected on described cross bar, described support arm is fixed on described casing by fulcrum, and described snubber assembly comprises at least one hydraulic cushion bar.
Preferably, this single-blade falling machine also comprises column, and the upper end of described column is fixedly connected with described cross bar, and described column is parallel with described upright guide rail.
Preferably, the hydraulic cushion bar that the snubber assembly of this single-blade falling machine comprises is two.
Wherein, described hydraulic cushion bar comprises buffering cylinder body, piston, spring and the body of rod, and described piston is connected by described spring and is engaged in described buffering cylinder body with the described body of rod and moves, and described buffering body of rod inside is marked with hydraulic oil.
Compared with prior art; the utlity model has following beneficial effect: utilize hydraulic principle to reach the effect of buffering, avoid rigid impact to produce huge noise, protected snubber assembly simultaneously; promote testing efficiency, extended the serviceable life of single-blade falling machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model hydraulic cushion bar.
Embodiment
Below in conjunction with specific embodiment, a kind of single-blade falling machine of the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, the utility model proposes a kind of single-blade falling machine, comprise chain 1, casing 2, support arm 3, hydraulic cushion bar 4, upright guide rail 5, cross bar 6 and column 7; Upright guide rail 5 upper ends are fixedly connected with cross bar 6, are fixedly connected with chain 1 on cross bar 6, and the other end of chain 1 is fixedly connected with casing 2, for driving casing 2 to move on upright guide rail 5; Support arm 3 is fixed on casing 2 by a fulcrum, on casing 2, be provided with two hydraulic cushion bars 4, hydraulic cushion bar 4 comprises buffering cylinder body 41, piston 42, spring 43 and the body of rod 44, piston 42 is connected by spring 43 with the body of rod 44 and is engaged in the interior motion of buffering cylinder body 41, and the buffering body of rod 41 inside are marked with hydraulic oil; Column 7 and its upper end parallel with upright guide rail 5 is fixedly connected with cross bar 6, plays the fixing effect of supporting; In the time that falling, support arm 3 cushioned by clashing into hydraulic cushion bar 4.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; any be familiar with those skilled in the art the utility model disclose technical scope in, the variation that can expect easily or replacement, all should be encompassed in protection domain of the present utility model in.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim was defined.
