And the left supporting arm and the right supporting arm are connected through a third pin hinge.
The first crank, the second crank and the sliding column are connected through a first pin hinge.
One end of the first crank, which extends out of the sliding column cavity, is hinged with the left supporting arm through a second pin;
one end of the second crank, which extends out of the sliding column cavity, is hinged with the right supporting arm through a fourth pin.
The invention has reasonable, scientific and advanced structure, and the structure of the invention is as follows: the clamping and lifting device comprises a lifting ring, a sliding column, a left supporting arm, a right supporting arm and a crank (comprising a first crank and a second crank); the sliding column is fixed at the lower end of the lifting ring, the left supporting arm and the right supporting arm are positioned on two sides of the sliding column guide sleeve and distributed in an opposite mode and connected with the sliding column through 2 opposite cranks (a first crank and a second crank), the upper end of the sliding column is connected with the 2 cranks (the first crank and the second crank) through a first pin, and one end, extending out of a sliding column cavity, of the first crank is hinged with the left supporting arm through a second pin; one end of the second crank, which extends out of the sliding column cavity, is hinged with the right supporting arm through a fourth pin; the left and right supporting arms are connected through a third pin.
The invention has the beneficial effects that: because this device design is the clamp type, the heavier the work piece, the clamp force is bigger, the work piece is difficult to the landing more. The workpiece can be very conveniently hoisted and unloaded. The problem of the hoist too simple, hoist and mount work piece security poor is solved. The lifting device has the characteristics of safety, convenience, simplicity and practicability for lifting deep cylinder type workpieces, straight cylinder type parts and disc type parts. The device has the advantages of simple structure, convenient installation, low manufacturing cost and easy popularization.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: the device comprises a lifting ring 1, a sliding column 2, a first crank 3-1, a second crank 3-2, a left supporting arm 4, a right supporting arm 5, a third pin 6, a second pin 7-1, a fourth pin 7-2 and a first pin 8.
Detailed description of the invention
The invention is further described with reference to specific examples. The scope of the invention is not limited thereto;
an internal supporting type clamping and hoisting device for hoisting a workpiece comprises a hoisting ring 1, a sliding column 2, a left supporting arm 4, a right supporting arm 5, a first crank 3-1 and a second crank 3-2; the sliding column 2 is fixed at the lower end of the hanging ring 1, and the left supporting arm 4 is hinged with the right supporting arm 5; a sliding column cavity is arranged in the sliding column 2, and open slots communicated with the sliding column cavity are formed in two sides of the sliding column 2;
the first crank 3-1 and the second crank 3-2 are located in a sliding column cavity of the sliding column 2, the first crank 3-1, the second crank 3-2 and the sliding column 2 are connected through hinges, and the first crank 3-1 and the second crank 3-2 extend out of the sliding column cavity of the sliding column 2 through an open slot.
Furthermore, one end of the first crank 3-1, which extends out of the sliding column cavity of the sliding column 2, is hinged with the left supporting arm 4; one end of the second crank 3-2 extending out of the sliding column cavity of the sliding column 2 is hinged with the right supporting arm 5; the left supporting arm 4 and the right supporting arm 5 are positioned on two sides of the sliding column 2 and distributed oppositely. The left arm 4 and the right arm 5 are hinged by a third pin 6. The first crank 3-1, the second crank 3-2 and the sliding column 2 are hinged through a first pin 8. One end of the first crank 3-1, which extends out of the sliding column cavity of the sliding column 2, is hinged with the left supporting arm 4 through a second pin 7-1; one end of the second crank 3-2 extending out of the slide column cavity of the slide column 2 is hinged with the right supporting arm 5 through a fourth pin 7-2.
All parts (including the lifting ring 1, the sliding column 2, the first crank 3-1, the second crank 3-2, the left supporting arm 4 and the right supporting arm 5) are made of 45# steel and Q235B steel plates, and the parts are simple to machine and manufacture and convenient to install. Can be used for hoisting workpieces with the mass of less than 300 kg. When the lifting device is used, the left supporting arm 4 and the right supporting arm 5 are placed in a deep cylinder type workpiece, a lifting hook of a crane hooks the lifting ring 1, the sliding column 2 slides upwards, and the crank (comprising the first crank 3-1 and the second crank 3-2) drives the left supporting arm 4 and the right supporting arm 5 to move outwards to clamp the workpiece.
