Detailed Description

To achieve the above objects, features and advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, the present invention will be described in detail with reference to the accompanying drawings.

Example 1

A swing arm type anti-inclination safety lock for a hanging basket is shown in a figure 1 or 3 and comprises a fixing plate 1 and rollers 4, wherein a waist-shaped hole 2 is formed in the fixing plate 1 as shown in a figure 1 or 5, and a swing arm 3 is arranged between the fixing plate 1 and the rollers 4. The swing arm 3 is fixed on the fixing plate 1 through a positioning screw 5, and the swing arm 3 can rotate around the positioning screw 5. One end of the swing arm 3 is fixed on the waist-shaped hole 2 of the fixing plate 1 through a sliding screw 6, the sliding screw 6 can slide up and down in the waist-shaped hole 2, and the waist-shaped hole 2 is used for limiting the rotating angle of the swing arm 3; the other end of the swing arm 3 is fixedly connected with the roller 4 through a first screw 13. A rope blocking plate 7 is arranged between the swing arm 3 and the roller 4, the number of the rope blocking plates 7 is two, a second screw 14 is fixed between the two rope blocking plates 7, and a working steel wire rope is arranged between the second screw 14 and the roller 4.

As shown in fig. 2 or 4, the number of the fixing plates 1 is two, a right rope clamp 11, a wedge block 8 and a left rope clamp 12 are arranged between the two fixing plates 1, a needle row 9 is arranged on the right rope clamp 11, the wedge block 8 is fixedly connected with the swing arm 3 through a sliding screw 6, the wedge block 8 is attached to the needle row 9 and can slide up and down along the needle row 9, the needle row 9 is parallel to the axis (dotted line in fig. 5) of the waist-shaped hole 2 on the fixing plate 1, and the swing arm 3 drives the sliding screw 6 and the wedge block 8 to slide up and down along the needle row 9 when rotating. A spring 10 is arranged between the wedge block 8 and the right rope clamp 11, and a safety steel wire rope is arranged between the wedge block 8 and the left rope clamp 12. When the swing arm 3 is not subjected to external force, the spring 10 pushes the wedge block 8 to move upwards, so that the swing arm type anti-tilting safety lock for the hanging basket is in a locking state.

As shown in fig. 8, the anti-tilt safety locks are fixed at two ends of the hanging platform of the hanging basket by bolts, are positioned above the hoisting machine, are inserted into the working steel wire rope of the hoisting machine and tightly lean between the second screw 14 and the roller 4, open the swing arm type anti-tilt safety locks, and the safety steel wire rope passes through the swing arm type anti-tilt safety locks and can freely slide.

The utility model discloses a theory of operation: as shown in fig. 6 or 7, when the suspension platform is in a horizontal state or the inclination angle is not large, the working steel wire rope leans between the second screw 14 and the roller 4, the swing arm 3 pulls the sliding screw 6 and the wedge block 8 to move downwards to the lowest position, and the spring 10 is compressed, so that the swing arm type anti-tilt safety lock is in an unlocked state, and the safety steel wire rope can slide freely in the swing arm type anti-tilt safety lock. When the inclination angle of the suspension platform is increased or the working steel wire rope is broken, the pressure on the swing arm type anti-inclination safety lock roller 4 pressed at the lower end of the suspension platform disappears, the swing arm 3 rotates by taking the positioning screw 5 as the center under the double actions of self weight and the pressure of the spring 10, so that the sliding screw 6 and the wedge block 8 move upwards along with the needle roller row 9 until the safety steel wire rope is locked, and the suspension platform is prevented from continuously inclining or one end of the suspension platform is prevented from falling.

The protection scope of the present invention is not limited to the above embodiments, and any modifications, equivalent replacements, and improvements that can be made by a person skilled in the art within the spirit and principle of the present invention should be included in the protection scope of the present invention.
