Abstract
An emergency cabin throwing tester comprises a bottom supporting pillar and a beam rack structure fixedly connected above the bottom supporting pillar. A sensor clamp, an accelerator sensor and a cabin clamp to-be-tested are arranged under the beam rack structure from top to bottom, and an electric hoist track with two electric hoists is arranged in the beam rack structure. Hoisting of the cabin can be realized through cooperation between the electric hoists and cabin clamp to-be-tested which is respectively connected with a horizontal loading mechanism, a vertical loading mechanism and a front and rear loading mechanism being perpendicular to the horizontal loading mechanism and forming a plane with the vertical loading mechanism. The emergency cabin throwing tester in such a structure can safely and accurately tests the throwing performance of the cabin under various conditions and is suitable for cabins in different shapes. The emergency cabin throwing tester improves test efficiency and lowers production cost.
Description
Technical field
The utility model relates to a kind of gondola ground test device, relates in particular to the Performance Detection special purpose test equipment that a kind of gondola is in case of emergency thrown in the air.。
Background technology
Gondola is that aerial throwing put one of vitals of equipment, and its performance under jury launch condition directly has influence on the safety of gondola interior items.Due to reasons such as design, manufactures, the performance of gondola under jury launch condition exists error.This error size is one of important performance indexes of gondola.Therefore, the performance test of gondola under jury launch condition is very necessary.At present, still there is no the special purpose test equipment of the performance test under jury launch condition for detection of gondola.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gondola jury launch test unit, can accurately detect the various performance parameters under gondola jury launch on ground.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of gondola jury launch test unit, comprise the support column of bottom and the beam frame structure that top is fixedly connected with thereof, the below of beam frame structure is provided with clamp of sensor, acceleration transducer and gondola fixture to be measured from top to bottom successively, in beam frame structure, be also provided with electric block track, electric block track is provided with two electric blocks, coordinates the lifting that realizes gondola to be measured by electric block with gondola fixture to be measured; On gondola to be measured, be connected with respectively horizontal load maintainer, vertical loading mechanism and the front and back load maintainer perpendicular to horizontal load maintainer and vertical loading mechanism formation plane; Described horizontal load maintainer, vertical loading mechanism and front and back load maintainer include hydraulic cylinder, power sensor and wire rope, and one end of wire rope is connected to hydraulic cylinder by power sensor, and the other end is connected to gondola to be measured after adjusting direction by deflection sheave.
Described device also comprises the Hydraulic Station being connected with hydraulic cylinder; It is mainly used to provide power source to the hydraulic cylinder of each load maintainer.
Described support column is four, vertically arranges, and the beam frame structure of its top adopts many horizontal supports and bearing diagonal to be formed by connecting, horizontal support and bearing diagonal and between form multiple triangles, make its Stability Analysis of Structures.
Described support column is that reinforced concrete is made.Support column is used for supporting and fixed beam shelf structure.Beam frame structure is mainly the test gondola for installation and fixing different size.
Described electric block track is positioned at the top of gondola fixture to be measured.In order to test and gather the input acceleration of gondola to be measured under specified load, above test gondola fixture, be fixed wtih clamp of sensor and acceleration transducer.Simultaneously, because gondola weight, the volume difference of different size are larger, in order to realize safe and efficient being installed to above test gondola fixture of gondola, above test gondola fixture in beam frame structure, be provided with electric block track, thereby ensure that the electric block of both sides can horizontally slip in the time of lifting different size gondola.
The groundwork principle of described each load maintainer is: hydraulic cylinder is fixed, and hydraulic cylinder is connected with wire rope by power sensor.In the time that the piston of hydraulic cylinder stretches, will drive wire rope 1 to pull gondola to be measured along its axial direction, thereby realize, test gondola is loaded, for the loading of different directions, by adopting one or more deflection sheave to regulate as required.In the process loading, power sensor will record the pulling force data that gondola to be measured bears.Detect thereby can realize the input performance test of gondola under 0-15 ton pulling force, horizontal direction 0-0.5 ton pulling force, fore-and-aft direction 0-0.5 ton pulling force integrated condition vertically downward, gather the data such as car speed, acceleration, reacting force simultaneously.
The utility model adopts above-mentioned design, and the input performance under can every integrated condition of measuring gondola of safety and precise, and the gondola of applicable difformity specification, adopt this device, reduced production cost when can improving testing efficiency.
