Abstract
A test piece ejector comprises a four-jaw chuck, an upper pressing plate, a chuck control rotating handle, a support frame, a slide lifting table, a hydraulic lift, a hydraulic punching device and a bottom plate. An ejection hole is arranged at the center of the upper pressing plate, the four-jaw chuck corresponding to the ejection hole is arranged on the upper pressing plate, the chuck control rotating handle is arranged on the upper pressing plate, the upper pressing plate is fixed to the upper end of the support frame, the bottom plate is fixed at the lower end of the support frame, the slide lifting table is arranged in the middle of the support frame in a guided manner, a punching hole is arranged on the slide lifting table, the hydraulic lift and the hydraulic punching device are mounted on the bottom plate, the upper end of the hydraulic lift is connected to the bottom of the slide lifting table, and the hydraulic punching device is aligned to the punching hole. The test piece ejector is convenient and rapid to operate, easy in ejection, wide in applicable specification range and easy to popularize and use, the qualification rate of a test piece is increased, manual operation steps are fewer, and labor and time are saved.
Description
Technical field:
The utility model relates to the road construction equipment technical field, relates in particular to a kind of test specimen stripper.
Background technology:
In the construction of the highway process, for identifying unit weight, water cut and the mechanical property of soil, oil pitch prill concrete road material, sub-surface compound, need the test specimen of preparation different size at present, be used for various tests.For pitch prill road material or concrete sample are conveniently deviate from, need to add very large power to test specimen from the mould cylinder.At present the strippers that use in a large number of highway engineering department are the leading screw pressuring method, rotate test specimen in the pressing mold cylinder of downward top by leading screw, allow test specimen deviate from from the mould cylinder, fall within on the pallet with spring.This stripper has following two shortcomings: (1) because leading screw top power is limited, some test specimen demouldings difficulty, particularly in large specification test specimen, be difficult to eject; (2) carriage insufficient height, spring force is softer, drops on after test specimen is deviate from from the mould cylinder often to occur the crack on the pallet, even disconnects, and can not guarantee the qualification rate of test specimen.
The utility model content:
The purpose of this utility model is to provide a kind of test specimen stripper, solves the problem of sampling test specimen demoulding difficulty, improves the qualification rate of test specimen, and manual steps is few, saves muscle power and time.
The technical scheme that its technical matters that solves the utility model adopts is: it comprises four-jaw chuck, top board, chuck control swing handle, bracing frame, slip lifting table, hydraulic hoist, hydraulic pressure punch die device, base plate, there is demoulding hole at the top board center, corresponding demoulding hole is provided with four-jaw chuck on the top board, and chuck control swing handle is set on the top board; Top board is fixed on the bracing frame upper end, at bracing frame lower end fixed base plate, guiding arranges the slip lifting table at the bracing frame middle part, be provided with the punch die hole on the slip lifting table, at base plate hydraulic hoist and hydraulic pressure punch die device are installed, the hydraulic hoist upper end connects slip lifting table bottom, and hydraulic pressure punch die device is aimed at the punch die hole.During use, to treat that demoulding test specimen is placed on the slip lifting table, rise the slip lifting table by hydraulic hoist, when treating that test specimen top arrives top board, the lifting table that stops to slide rises, and rotating chuck control swing handle makes four-jaw chuck block test specimen mould top, starts hydraulic pressure punch die device, beginning punching press test specimen makes test specimen break away from gradually the test specimen mould.
The utility model structure is exquisite, and convenient to operation, the demoulding is easy, and applicable specification is extensive, improves the qualification rate of test specimen, and manual steps is few, saves muscle power and time, is easy to promote the use of.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
With reference to Fig. 1, the utility model four-jaw chuck 1, top board 3, chuck control swing handle 4, bracing frame 5, slip lifting table 6, hydraulic hoist 8, hydraulic pressure punch die device 9, base plate 10, there is demoulding hole 2 at top board 3 centers, corresponding demoulding hole 2 is provided with four-jaw chuck 1 on the top board 3, and chuck control swing handle 4 is set on the top board 3; Top board 3 is fixed on bracing frame 5 upper ends, at bracing frame 5 lower end fixed base plates 10, guiding arranges slip lifting table 6 at bracing frame 5 middle parts, be provided with punch die hole 7 on the slip lifting table 6, at base plate 10 hydraulic hoist 8 and hydraulic pressure punch die device 9 are installed, hydraulic hoist 8 upper ends connect slip lifting table 6 bottoms, and hydraulic pressure punch die device 9 is aimed at punch die hole 7.During use, to treat that demoulding test specimen is placed on the slip lifting table 6, rise slip lifting table 6, when treating that test specimen top is pressed onto on the top board 3, the lifting table 6 that stops to slide rises, rotating chuck control swing handle 4, make four-jaw chuck 1 block test specimen mould top, prevent that the test specimen mould from moving, start hydraulic pressure punch die device 9, beginning punching press test specimen makes test specimen break away from gradually the test specimen mould.
