Detailed Description
Example one
Fig. 1 is the utility model relates to a hoisting structure schematic diagram of box component hoist embodiment one, fig. 2 is the utility model relates to a lifting hook structure schematic diagram of box component hoist embodiment one, fig. 3 is the utility model relates to a lifting hook orthographic view structure schematic diagram of box component hoist embodiment one. As shown in the figure, a box member spreader comprises two hooks 1 which are symmetrically arranged. The top of the hook 1 is provided with stabilizing arms 5 in the direction of the other hook 1, i.e. stabilizing arms 5 are provided on opposite sides of the two hooks 1. The upper part of the hook 1 is provided with a latch arm 6, the latch arm 6 being located directly below the stabilizing arm 5. Stabilizing arm 5 is parallel to latch arm 6 and the length of stabilizing arm 5 is greater than the length of latch arm 6.
The stabilizing arm 5 and the end of the lock catch arm 6 far away from the lifting appliance are both provided with a mounting plate 2, one end of the mounting plate 2 is rotatably connected with the stabilizing arm 5 or the lock catch arm 6 through a pin shaft or a bolt, namely, the ends of the stabilizing arm 5 and the lock catch arm 6 are provided with connecting holes, the mounting plate 2 is also provided with connecting holes, and the pin shaft or the bolt penetrates through the connecting holes to connect the stabilizing arm 5 and the locking arm with the mounting plate 2. The aperture of the connecting hole is slightly larger than the diameter of the pin shaft or the bolt, so that the mounting plate 2, the stabilizing arm 5 and the locking arm can rotate freely. The two ends of the pin shaft are limited through the clamp spring, the clamp pin or the nut, and the pin shaft is prevented from slipping from the mounting plate 2, the stabilizing arm 5 or the lock catch arm 6. The other end of mounting panel 2 rotates and is provided with pulley 10, and pulley 10 is located between two mounting panels 2, rotates through the bolt between pulley 10 and the mounting panel 2 and is connected, and the center of pulley 10 is provided with the through-hole that makes the bolt pass, and the aperture of through-hole is greater than the diameter of bolt for pulley 10 can rotate between two mounting panels 2.
The two lifting hooks 1 are connected through a steel cable 3, and the steel cable 3 is wound on pulleys 10 on the two lifting hooks 1. The pulley 10 can improve the force transmission of the two hooks 1 and prevent the hooks 1 from damaging the steel cable 3. The latch arms 6 of the two hooks 1 are connected through the steel cable 3, so that the two hooks 1 can work cooperatively. The stabilizing arm 5 is used for tightening the steel cable 3, so that the lateral stability of hoisting is ensured, and the stress angle is effectively reduced.
The bottom end of the lifting hook 1 is obliquely upwards provided with a bearing arm 11, and the bearing arm 11 is positioned under the latch arm 6. The bearing arm 11 is used for hooking the lower part of the workpiece 7 (box-shaped member), and the bearing arm 11 arranged obliquely upwards can effectively prevent the unhooking phenomenon in the hoisting process and improve the hoisting stability.
