Detailed Description
The following describes embodiments of the present invention with reference to the drawings.
As shown in fig. 1 to 7, the spreader special for flat bulb steel of the present invention comprises two identical side plates 5 and a middle plate 6 clamped between the two side plates 5;
the middle plate 6 is vertically provided with an upper opening, a middle opening 2 and a lower opening;
the upper opening is a lifting hole 1;
the middle opening 2 is formed by splicing a rectangular opening and two semicircular openings; the length direction of the rectangular opening is vertical, and the diameters of the two semicircular openings are spliced with the two widths of the rectangular opening respectively;
the lower opening is formed by splicing a first lower opening 31 and a second lower opening 32 which are identical to the middle opening 2, wherein the first lower opening 31 is vertical, and the second lower opening 32 is obliquely and upwards connected to the top end of the first lower opening 31; the top end semicircle of the first lower opening 31 is overlapped and spliced with the bottom end semicircle of the second lower opening 32;
the middle opening 2 coincides with the vertical central axis of the first lower opening 31;
two pin shaft holes 4 are vertically formed in each side plate 5, and the distance between the circle centers of the two pin shaft holes 4 is d; the distance between the center of the bottom semicircle of the middle opening 2 and the center of the bottom semicircle of the first lower opening 31 is also d;
a first pin shaft 91 is arranged through the pin shaft holes 4 at the upper parts of the two side plates 5 and the middle opening 2 of the middle plate 6;
a second pin shaft 92 is arranged through the pin shaft holes 4 at the lower part of the two side plates 5 and the lower opening of the middle plate 6;
the lower end of the middle plate 6 is provided with a linear bulge, and the lower end of the side plate 5 is provided with a hook;
when the first pin shaft 91 and the second pin shaft 92 move to the bottom dead center, the linear protrusion and the hook form a small clamping space for clamping the top of the flat-bulb steel 7; when the first pin 91 moves to the top dead center and the second pin 92 rotates to the top end of the second lower opening 32, the linear protrusion and the hook form a larger clamping space for releasing the flat bulb steel 7.
The diameter of the pin shaft hole 4 is the same as the diameter of the semicircle at the bottom of the middle opening 2.
The upper opening is circular.
The upper opening coincides with the vertical central axis of the middle opening 2.
The first pin shaft 91 and the second pin shaft 92 are vertically provided with a limiting piece at both ends.
The first pin shaft 91 and the second pin shaft 92 are both bolts, and both ends of the first pin shaft 91 and the second pin shaft 92 are connected with limit nuts 8.
The diameters of all the pin shaft holes 4 on the two side plates 5, the diameter of the first pin shaft 91 and the diameter of the second pin shaft 92 are the same.
When the locking device is used, when the first pin shaft 91 and the second pin shaft 92 are moved to the bottom dead center (so that the two side plates 5 are at the bottom dead center, as shown in fig. 6), the straight line protrusion and the hook form a small clamping space for clamping the top of the flat-bulb steel 7, which is in a locking state; at the moment, the flat-bulb steel 7 can be hoisted by hooking the hoisting hole 1 by using a hoisting hook of a crane;
next, the first pin 91 is moved to the top dead center (as shown in fig. 5), and then the second pin 92 is rotated to the top end of the second lower opening 32, so that the linear protrusion and the hook form a large clamping space for releasing the flat bulb steel 7, as shown in fig. 4.
