Abstract

The utility model relates to a hydraulic gravity loading test tooling of a hydraulic cylinder, belonging to a testing device of the hydraulic cylinder and comprising a base (1), an inclined beam (2), a vertical column (3), a cross beam (4), U-shaped supports (5) and a weight hopper (6), wherein one end of the base is provided with the vertical column; the inclined beam is connected between the vertical column and the base; one end of the cross beam (4) is hinged with the vertical column (3) on the base (1), and the other end thereof is hinged with the weight hopper (6); and the cross beam (4) and the inclined beam of the base are respectively provided with two rows of threaded holes which are respectively connected with the U-shaped support (5). The hydraulic gravity loading test tooling has the advantages of having simple structure, improving the quantity of loading the weight blocks, being capable of realizing loading with different weight, being capable of realizing gravity loading test of the cylinders with different lengths by adjusting the positions of the U-shaped supports, having good universality, being capable of simulating the real working conditions of variable-amplitude cylinders of automobile hoists, variable-amplitude cylinders of excavators and the like, and being capable of carrying out the pressure-resistant test, the gravity impact test and the buffering performance test of the cylinders on the cylinders.

Description

Oil hydraulic cylinder hydraulic pressure gravity load test frock
Technical field
The utility model relates to a kind of testing apparatus of oil hydraulic cylinder, particularly a kind of oil hydraulic cylinder hydraulic pressure gravity load test frock.
Background technique
At present, a lot of machineries promote weight by oil hydraulic cylinder, especially on engineering machinery such as truck crane, excavator, generally adopt oil hydraulic cylinder to promote weight, when utilizing the oil hydraulic cylinder lifting weight on the engineering machinery, this oil hydraulic cylinder is carried out the gravity load test, this method versatility is bad, can only carry out the gravity load test to specific oil hydraulic cylinder, more can not carry out gravity test to the oil hydraulic cylinder of different length series.
The model utility content
The purpose of this utility model is to provide a kind of: the frock that versatility is good, can carry out the oil hydraulic cylinder hydraulic pressure gravity load test of gravity load test to the oil hydraulic cylinder of different length series.
The purpose of this utility model is achieved in that this gravity loads frock and comprises base (1), cant beam (2), column (3), crossbeam (4), U type bearing (5), weight bucket (6), end at base has column, between column and base, be connected with cant beam, column (3) on crossbeam (4) one ends and the base (1) is hinged, the hinged weight bucket of the other end (6); Two row's tapped holes are respectively arranged on crossbeam (4) and the base cant beam, on tapped hole, respectively connect a U type bearing (5).
Described base is welded by five beams, constitutes a rectangle, also is connected with oblique straining beam on base, wherein has a girder to be positioned at the neutral position of base, and column and cant beam are connected on the girder.
Beneficial effect: owing to adopted such scheme, the column on crossbeam one end and the base is hinged, and crossbeam can rotate around articulating point; On tapped hole, respectively connect a U type bearing.Change the position that U type bearing is installed in different tapped holes, can realize the installation of different length oil hydraulic cylinder, versatility is good; The cylinder bottom of oil hydraulic cylinder is hinged on the base on the cant beam, hydraulic cylinder piston rod is hinged on the crossbeam, two row's mounting holes are respectively arranged on the mounting plate of cant beam and crossbeam, select suitable mounting hole according to the length of oil hydraulic cylinder, the hinged gravity of beam-ends loads bucket, by loading the loading that the weight block of placing different quality in the bucket realizes different gravity at gravity, can carry out the gravity load test to the oil hydraulic cylinder of different length series, reached the purpose of this utility model.
Advantage: simple in structure, change the quantity that loads weight block, can realize the loading of Different Weight; Can realize the gravity load test of different length oil cylinder by the position of adjusting U type bearing, versatility is good; Can simulate as real operating mode such as truck crane amplitude oil cylinder, excavator amplitude oil cylinder; Can carry out pressure test, gravity shock test, cylinder buffer performance test to oil cylinder, test result is significant to performance and the reliability that improves oil hydraulic cylinder.
Description of drawings
Fig. 1 is that the utility model oil hydraulic cylinder gravity loads tool structure figure.
Fig. 2 is that the utility model oil hydraulic cylinder gravity loads the frock plan view.
Among the figure, 1, base; 2, cant beam; 3, column; 4, crossbeam; 5, U type bearing; 6, weight bucket.
Embodiment
Embodiment 1: this gravity loads frock and comprises base 1, cant beam 2, column 3, crossbeam 4, U type bearing 5, weight bucket 6, end at base has column, be connected with cant beam between column and base, the column on crossbeam 4 one ends and the base 1 is hinged, the hinged weight bucket 6 of the other end; Two row's tapped holes are respectively arranged on crossbeam 4 and the base cant beam, on tapped hole, respectively connect a U type bearing 5.
Described base is welded by five beams, constitutes a rectangle, also is connected with oblique straining beam on base, wherein has a girder to be positioned at the neutral position of base, and column and cant beam are connected on the girder.Base and contact area of ground are big, and integral body is toppled when preventing that gravity from loading.
The column upper end of crossbeam 4 one ends and base 1 is hinged, can rotate around articulating point, and the hinged weight bucket 6 of the other end, weight bucket 6 interior weight block of placing different quantity realize the loading of different gravity.Two row's tapped holes are respectively arranged on crossbeam 4 and the base cant beam, and U type bearing 5 is installed in the different tapped holes, realizes the installation of different length oil hydraulic cylinder.
