technical field

The utility model relates to a hand-operated demoulding device, in particular to a hand-operated hinge type demoulding device.

Background technique

Cylinder test specimens are often involved in civil engineering, such as concrete specimens, petroleum asphalt concrete specimens, and mixture specimens in material tests, compaction tests, soil density, and exploration earth-taking tools in geotechnical tests. These test specimens all need to use a stripper to remove the specimens from the mold before the test. Most of the existing demoulding devices use hydraulic jacks, which often have the following disadvantages: hydraulic jacks leak oil, which pollutes the environment; hydraulic jacks have a small single stroke, and need to be drained and retracted repeatedly, which affects work efficiency; Different from the lowering operation position and method, the operation continuity is poor, and the lifting speed cannot be adjusted according to the needs.

The lifting pallet (2) is a plane plate with a demoulding hole (11-2) in the middle, which can be adjusted up and down according to the height of the mold cylinder, and fixed on the support frame (3) by the fixing knob (10);

The sample pushing plate (4) is fixed on the lifting screw (5) through a built-in internal thread, and the sample pushing plate (4) can be changed in size according to the inner diameter of the mold cylinder;

The lifting screw (5) is fixed on the internal threaded pipe (6), and the length of the protruding internal threaded pipe can be adjusted according to the height of the mold cylinder, and the test piece can be smoothly pushed out from the mold cylinder at one time through the lifting hinge mechanism (7);

The internal thread pipe (6) is fixed on the top of the lifting hinge mechanism (7), and the lifting screw (5) and the bulldozer (4) are pushed up and down with the lifting hinge mechanism (7);

The lifting hinge mechanism (7) consists of four left and right chain rods connected by chain hinges to form two parallel quadrilateral movable mechanisms on the left and right. The two quadrilateral movable mechanisms are rotated by the driving screw (8). stretch up and down;

The driving screw (8) is installed in the middle of the quadrilateral movable mechanism on the left and right sides of the lifting hinge mechanism (7), and the lifting hinge mechanism (7) is driven up and down by shaking and turning the hand wheel (9) to generate forward and backward movement. sports.
