[0021] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments, and the following embodiments do not limit the utility model involved in the claims. In addition, not all combinations of features described in the embodiments are necessarily required for the solution of the utility model.
[0022] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments. Example
[0023] like Figure 1 、 2 As shown in Figure 3, an engineering material transfer auxiliary device includes a grabbing mechanism and a traction rope 1 for lifting the grabbing mechanism upward, the grabbing mechanism includes a first grabbing component, the first grabbing component includes a first clamping jaw and a second clamping jaw, the first clamping jaw and the middle part of the second clamping jaw are rotatably connected by a hinge shaft 2, the two ends of the first clamping jaw and the second clamping jaw are respectively the first end and the second end, the first end of the first clamping jaw and the second clamping jaw are provided with a first clamping part, the first clamping part is a bending part relative to the inner side of the grabbing mechanism, the second end of the first clamping jaw is connected to the traction rope, the second end of the second clamping jaw is provided with a second guide part, and the traction rope slides around the guide part to pull the grabbing mechanism upward. Pull the traction rope upward, the traction rope makes the second ends of the first clamp and the second clamp approach each other, so that the first clamping part 9 of the second end of the first clamp and the second clamp are close to each other to clamp the material. The friction force generated by the material and the first clamp is balanced with gravity, so that the object remains stable. Then use a crane or other device to pull the traction rope to lift the material 12 to the required place. After lifting it to the place where it needs to be placed, the traction rope is lowered, so that the material is lowered and placed where it needs to be placed. Continue to pull the rope below. Under the action of gravity, the second ends of the first clamp and the second clamp move away from each other, so that the grabbing mechanism opens. Then the worker can take away the material, and the grabbing mechanism will grab the next material.
[0024] Furthermore, it also includes a second grasping assembly, the second grasping assembly includes a third jaw and a fourth jaw, the middle parts of the third jaw and the fourth jaw are rotatably connected by a hinge shaft, the two ends of the third jaw and the fourth jaw are respectively a first end and a second end, the first end of the third jaw and the fourth jaw is provided with a second clamping portion, the second end of the third jaw and the fourth jaw is respectively provided with a third guide portion and a fourth guide portion, and the traction rope slides around the third guide portion and the fourth guide portion to pull the grasping mechanism upward. In this way, when the traction rope is pulled upward, the first jaw and the second jaw, and the third jaw and the fourth jaw can be closed to grasp the material, and because the first grasping assembly and the second grasping assembly are pulled by the same traction rope, even if one of the grasping assemblies cannot continue to close, the other grasping assembly can continue to close without affecting each other, so that the two grasping assemblies grasp different parts of the material, thereby being suitable for grasping complex material shapes.
[0025] Furthermore, the third and fourth grippers form a portal-shaped frame, comprising two parallel outer vertical bars 3, the lower ends of which serve as the second clamping portion 4. The upper ends of the two outer vertical bars are connected by an upper connecting rod 5, which serves as the guide. The upper connecting rods of the second, third, and fourth grippers are provided with guide wheels 6 for guiding the traction rope. The first and second grippers are located between the two parallel outer vertical bars. The first and second grippers form a frame structure, comprising two parallel inner vertical bars 7, the lower ends of which are connected by the first clamping portion, and the upper ends of which are connected by a lower connecting rod 8. The lower connecting rod of the second gripper serves as the guide, and the traction rope is connected to the lower connecting rod of the first gripper. This allows the first gripping assembly to be located inside the second gripping assembly, with the first gripping assembly used to grip the middle of an object, and the second gripping assembly used to grip both ends of an object.
[0026] The hinge shaft is connected to a bracket 10 located between the first and second clamping jaws, and the bracket is provided with a traction rope guide 11 located above the gripping mechanism. The guide includes two guide wheels, and the traction rope slides through between the two guide wheels, thereby providing a guide for the traction rope.
