Detailed Description
Example 1: as shown in fig. 1, 2, 3, 4, 5, a gravity-operated grab bucket, wherein the grab bucket 1 includes a grab bucket upper jaw and a grab bucket lower jaw (1.1, 1.2) hinged to each other, a single dacron belt 2 for lifting the grab bucket 1, a hook 3 connected to one end of the single dacron belt 2, a motor 4 connected to the other end, and a guide rail 5 for controlling the grab bucket 1 to move up and down along a fixed track, a slider 1.2.1 is disposed on the upper end of the grab bucket lower jaw 1.2, the slider 1.2.1 is slidably disposed with a slide groove of the guide rail 5, a protruding shaft 5.1 is disposed in the slide groove near the top end of the guide rail 5, a concave groove 1.2.2 disposed with the protruding shaft 5.1 is correspondingly disposed on the slider 1.2.1, the grab bucket lower jaw 1.2 is provided with a first hook portion 1.2.1, the grab bucket upper jaw 1.1 is provided with a second hook portion 1.1.1.1.1.1.1, the first hook portion 1.2.1 includes a first base 1.2.1, a second hook portion and a second hook 1.1.1.2.1.1.1.1.1.1.1 base including a second hook base 1.2 base body, the hook 3 is hooked in the first hook nest 1.2.1.2 or the second hook nest 1.1.1.1, the first base body 1.2.1.1 is a strip-shaped plate body, and the first hook nest 1.2.1.2 is a right angle formed by bending the end part of the strip-shaped plate body. The second substrate 1.1.1.1 is a strip-shaped plate body, and the second hook socket 1.1.1.2 is an arc-shaped groove formed by bending the strip-shaped plate body. The second hooking part 1.1.1 is located above the first hooking part 1.2.1, and the second hooking part 1.1.1.2 is located above the open side of the first hooking part 1.2.1.2. Couple 3 includes base member 3.1, has seted up the holding cavity 3.2 that link up on the base member 3.1, and this implementation base member is by the holding cavity 3.2 that upper and lower peg 3.1.1a, 3.1.1b and the connecting plate 3.1.2 at peg 3.1.1a both ends constitute, goes up peg 3.1.1a top and connects single dacron area 2, and lower peg 3.1.1b is colluded and is hung on first base member 1.2.1.1 or second base member 1.1.1. The upper jaw 1.1 and the lower jaw 1.2 of the grab bucket are provided with rotation limiting devices, which are not specifically described in the prior art, and the purpose of the rotation limiting device is to limit the rotation angle of the upper jaw 1.1, and specifically, the rotation limiting device can be a limiting angle steel as shown in fig. 1.
At the beginning, the grab bucket is in an opening state, at the moment, the hook 3 is hooked in the second hooking nest 1.1.1.2 of the second hooking part 1.1.1 of the upper jaw 1.2 of the grab bucket, the motor is controlled to run anticlockwise, along with slow descending of the terylene tape 2, the sliding block 1.2.1 of the lower jaw 1.1 of the grab bucket rotates anticlockwise around the convex shaft 5.1 in the sliding groove at the top end of the guide rail 5, the lower jaw 1.1 of the grab bucket is slowly lowered to be in a vertical state, when the lower jaw 1.1 of the open-close grab bucket rotates to be vertical, the concave nest 1.2.2.1 of the sliding block falls off from the convex shaft 5.1, and the open-close grab bucket 1 slowly and stably descends along the guide rails 5 at two sides.
When the opening and closing grab bucket 1 falls to the bottom end of the guide rail 5, the lower jaw 1.1 of the grab bucket 1 can not descend, however, the terylene tape 2 is continuously lowered due to the anticlockwise rotation of the motor 4, the upper jaw 1.2 of the grab bucket can be closed anticlockwise along the hinge part 6 of the upper jaw 1.2, the lower jaw 1.1 under the action of gravity, after the upper jaw 1.2 of the grab bucket is closed, the hook 3 is continuously lowered along with the lowering of the terylene tape 2, the hook 1.1.1.2 can be separated from the second hook nest 1.1.1 of the second hook part 1.1, and the hook swings back to the vertical state under the action of gravity.
The motor 4 is controlled to rotate clockwise. Because the hook 3 swings back to a vertical state, the hook is just hooked in the first hooking pit 1.2.1.2 of the first hooking part 1.2.1 when rising, and the lower jaw 1.1 of the grab bucket is driven to rise along the guide rails 5 on the two sides in the clockwise rotation process of the motor 4. When the concave slot 1.2.2.1 of the slide block 1.2.2 of the grab bucket lower jaw 1.1 is embedded into the convex shaft 5.1 near the top end of the guide rail 5, the grab bucket lower jaw 1.1 rotates clockwise around the convex shaft 5.1 along with the continuous rising of the terylene tape 2. When rotated to 65 °, the hook 3 slides from the first recess 1.2.1.2 of the grapple lower jaw 1.1 into the second recess 1.1.1.2 of the upper jaw 1.2.
After the hook 3 is hooked in the second hook hole 1.1.1.2 of the grab bucket upper jaw 1.2, the grab bucket upper jaw 1.2 continues to rotate clockwise and is slowly opened, and the automatic opening and closing of the grab bucket is completed.
The described embodiments are only some embodiments of the invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
