Abstract
The utility model discloses a kind of loading platform drop test device, comprise proving installation body, it is characterized in that: described proving installation body comprises base, upper rack posts, lower fulcrum bar upper bracket and hinge, described proving installation body props up under loading platform, described upper rack posts, lower fulcrum bar are tilted by shaft foldable, described base is fixed on loading platform sill, and described hinge is located at the junction of upper rack posts and lower fulcrum bar, and described hinge is connected to linear electric motors by stay cord.The utility model supports loading platform by using dead point self-lock mechanism, by departing from dead point, realizing departing from the moment of loading platform, thus making loading platform obtain equivalent free-falling campaign.This structure also can install linear electric motors in bottom, by linear electric motors and rope, rotates hinge, realizes automatic operation.
Description
Technical field
The utility model relates to a kind of pick-up unit, particularly relates to the proving installation of a kind of loading platform tenesmus.
Background technology
Piler speed limit anti-drop device; rope-loosing protection device is verified by falling prevention test, and " JB5319.2 rail roadway stakcer crane safety standard " 4.2.7.2.1b article requirement, during test, " loading platform of jack-uping; loosen hoist rope, then removes lifting jack." this specifies poor operability, and falling stroke is not enough, the free-falling also in non-critical meaning.
Some producer adopts following method of operating: use support shaft loading platform, unclamp wire rope, manually knock pole, and pole is tilted, and loading platform drops, and completes test.The method is original simple and crude, operational hazards, and side force affects test effect simultaneously.Because detection method is undesirable, the security of operation of piler buries hidden danger.
Utility model content
The utility model provides a kind of loading platform drop test device, and the technical matters that solve is how to reach loading platform free-falling by the structural design of proving installation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of loading platform drop test device, comprise proving installation body, it is characterized in that: described proving installation body comprises base, upper rack posts, lower fulcrum bar, upper bracket and hinge, described proving installation body props up under loading platform, described upper rack posts, lower fulcrum bar are tilted by shaft foldable, described base is fixed on loading platform sill, described hinge is located at the junction of upper rack posts and lower fulcrum bar, and described hinge is connected to linear electric motors by stay cord.
Further, described base and described lower fulcrum bar are hinged by rotating shaft.
Further, described upper rack posts and described lower fulcrum bar are hinged by rotating shaft.
Further, described linear electric motors are arranged on sill.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages: the utility model supports loading platform by using dead point self-lock mechanism, by departing from dead point, realize departing from the moment of loading platform, thus make loading platform obtain equivalent free-falling campaign.This structure also can install linear electric motors in bottom, by linear electric motors and rope, rotates hinge, realizes automatic operation.
Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of loading platform drop test of the utility model device;
Fig. 2 is the proving installation body construction schematic diagram of a kind of loading platform drop test of the utility model device;
Fig. 3 is the left view of the proving installation body of a kind of loading platform drop test of the utility model device.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
First embodiment
With reference to figure 1, Fig. 2, Fig. 3, a kind of loading platform drop test device, comprise proving installation body 2, proving installation body 2 comprises base 5, upper rack posts 8, lower fulcrum bar 6, upper bracket 9 and hinge 7, proving installation body 2 is in loading platform 1 time, and upper rack posts 8, lower fulcrum bar 6 are tilted by shaft foldable, and base 5 is fixed on loading platform sill 4, hinge 7 is located at the junction of upper rack posts 8 and lower fulcrum bar 6, and hinge 7 is connected to linear electric motors by stay cord 3.
It is hinged that base 5 and lower fulcrum bar 6 pass through rotating shaft, and it is hinged that upper rack posts 8 and lower fulcrum bar 6 pass through rotating shaft, and linear electric motors are arranged on sill 4.
This proving installation 2 supports loading platform by using dead point self-lock mechanism, by departing from dead point, realizing departing from the moment of loading platform 1, thus making loading platform 1 obtain equivalent free-falling campaign.
Second embodiment
With reference to figure 1, Fig. 2, Fig. 3, a kind of loading platform drop test device, comprise proving installation body 2, proving installation body 2 comprises base 5, upper rack posts 8, lower fulcrum bar 6, upper bracket 9 and hinge 7, proving installation body 2 is in loading platform 1 time, and upper rack posts 8, lower fulcrum bar 6 are tilted by shaft foldable, and base 5 is fixed on loading platform sill 4, hinge 7 is located at the junction of upper rack posts 8 and lower fulcrum bar 6, and hinge 7 is connected to linear electric motors by stay cord 3.
It is hinged that base 5 and lower fulcrum bar 6 pass through rotating shaft, and it is hinged that upper rack posts 8 and lower fulcrum bar 6 pass through rotating shaft, and linear electric motors are arranged on sill 4.
This proving installation 2 supports loading platform 1 by using dead point self-lock mechanism, by departing from dead point, realizing departing from the moment of loading platform 1, thus making loading platform 1 obtain equivalent free-falling campaign.This structure also can install linear electric motors in bottom, by linear electric motors and rope 3, rotates hinge 7, realizes automatic operation.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
