Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 10, a lifting jig for gypsum blocks includes a main frame 1, one side of the main frame 1 is provided with a fixed splint 2 extending vertically downward, and the other side of the main frame 1 is pivotally connected with a fixed splint 2 parallel rotating shafts 3, on which a movable splint 4 extending downward is connected;

A guide seat 5 perpendicular to the main frame 1 is fixed in the middle of the main frame 1. A slide block 6 that can move up and down is installed on the guide seat 5. The lower end of the slide block 6 is provided with a hook groove 61 for spacing. The end face is fixed with the top face of an inverted U-shaped hanger 7, and the upper end face of the hanger 7 is fixed with a suspension hook 71;

The two side edges of the hanger 7 are pivotally connected to a movable connecting plate 8 through a pin shaft 72 respectively. The lower parts of the two movable connecting plates 8 are provided with substantially inverted triangle connecting holes 81, and two connecting rods fixed on the rotating shaft 3 9 are respectively connected with the inverted triangular connection holes 81 of the two movable splints 8 through pin shafts 91. When the tops of the two connecting rods 9 are in a free state, the two connecting rods 9 can drive the rotating shaft 3 to rotate and make the movable splint 4 go outward. turn;

The corresponding side of the hook groove 61 at the lower end of the slider 6 is provided with a limit assembly 10 that selectively limits the upward stroke of the slider 6 or does not limit the upward stroke of the slider 6 as the hanger 7 moves up and down.

Preferably, the limiting assembly 10 includes a wedge limiting seat 11, an upper wedge 12 and a lower wedge 13, the lower end of the wedge limiting seat 11 is connected with the main frame 1, and the upper end is connected with the guide seat 5, which can be The bottom of the wedge limit seat 11 is processed with a keyway-shaped through hole 111 and then fixed with the main frame 1 with bolts. An adjustment seat 51 is first fixed on the top of the guide seat 5, and the top of the wedge limit seat 11 is also processed with a keyway shape. The through hole 112 is connected with the adjusting seat 51 with a bolt, so that the distance between the wedge limiting seat 11 and the guide seat 5 can be adjusted conveniently.

The upper wedge 12 and the lower wedge 13 are pivotally mounted in the middle of the wedge limit seat 11, a part of the cylindrical groove 121 can be processed in the middle of the upper wedge 12, and a part of the cylinder 131 can be processed in the upper part of the lower wedge 13 , put the upper part of the cylinder 131 of the lower wedge 13 on the part of the cylindrical groove 121 in the middle of the upper wedge 12 to form a pivot connection;

The upper part of the inside of the wedge limit seat 11 is fixed with the guide block 14 when the upper wedge 12 moves up, the middle part of the inside of the wedge limit seat 11 is fixed with a positioning block 15, and the middle part of the upper wedge 12 is equipped with a telescopic block 122 and The positioning block 15 is matched, and the lower wedge 13 and the corresponding side of the hook groove 61 at the lower end of the slider 6 are provided with a matching protrusion 132, and the wedge limit seat 11 below the lower wedge 13 is equipped with a roller 16, and the lower wedge The bottom of 13 is provided with the curved surface 133 that is convenient to slide on roller 16.

Protrusions 21, 41 are provided on opposite sides of the fixed splint 2 and the movable splint 4, and anti-skid pads 17 are mounted on the projections 21, 41 .

Action principle of the present invention is as follows:

As shown in Fig. 3, when the present invention is placed on the block 20 to be grasped by the hoisting equipment, the movable splint 4 is deflected to the outside, and the upper wedge 12 and the lower wedge 13 lean against the telescopic block 122 installed in the middle of the upper wedge 12. On the positioning block 15, the upper wedge 12 and the lower wedge 13 are in the neutral position, at this moment, the slide block 6 can move up and down freely, the whole limit assembly 10 does not act as a limit to the slide block, and the clamp is in a relaxed state.

As shown in Figure 11, when the hoisting equipment extracts the hanger 7 through the hook 71, the hanger 7 drives the connecting rod 9, the rotating shaft 3, and the movable splint 4 to rotate clockwise through the movable connecting plate 8, and simultaneously extracts the slider 6 upwards, The movable splint 4 approaches the direction of the fixed splint 2 to clamp the block 20, and the whole fixture is in a clamped state, and the hoisting equipment can move the block 20 to the desired place through the present invention; at this time, the upper wedge 12 and the lower wedge The wedge 13 shifts downward due to the upward movement of the slider 6, and the upper wedge 12 and the lower wedge 13 slide down to the lower position along the roller 16, so as to prepare for limiting the upward stroke of the slider 6.

As shown in Figure 12, after the hoisting equipment moves the block 20 to the required place through the present invention; The hook groove 61 at the lower end of the slider 6 hooks the matching protrusion 132 of the lower wedge 13. When the hoisting equipment extracts the hanger 7 through the hook 71, the slider 6 pushes the lower wedge 13 and the upper wedge 12 upward simultaneously. Extraction, so that the upper wedge 12 and the lower wedge 13 are in the upper position. At this time, the upper wedge 12 and the lower wedge 13 act as a limit to the upward stroke of the slider 6, and the top ends of the two connecting rods 9 move relative to the two The inverted triangular connecting hole 81 of the connecting plate 8 is just in a free state and drives the rotating shaft 3 to rotate counterclockwise to make the movable splint 4 rotate outwards to loosen the block 20, and the lifting equipment can remove the present invention from the block 20; When the hanger 7 was put down again, the slide block 6 moved down, and the upper wedge 12 and the lower wedge 13 leaned against the positioning block 15 through the telescopic block 122 installed in the middle of the upper wedge 12, and the upper wedge 12 and the lower wedge 13 is in the neutral position and returns to the state shown in Figure 3 without taking the limit action on the upward stroke of the slide block 6, and the slide block 6 can move freely up and down again.

Therefore the present invention can realize that hanger 7 puts down and lifts movable splint 4 to be in the clamped state, then hanger 7 is put down again and then lifts movable splint 4 and is in the switch between the relaxed state, convenient to carry block 20.

The above is only a preferred embodiment of the present invention, and equivalent changes made by those skilled in the art according to the claims all fall within the protection scope of the present case.
