Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a simple material handling clamp. Background Technology

[0002] Construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into physical objects at a designated location. Common construction materials on construction sites include large boulders, demolished walls, and bricks. Manual handling is laborious, prone to injury, and poses certain safety hazards. Using mechanical equipment for handling is too cumbersome, inefficient, and slows down construction.

[0003] For example, Chinese utility model patent (CN216271307U) discloses a simple construction handling device, which describes: "It includes a pull rope, a pin, and a first clamp and a second clamp with the same structure. The first clamp and the second clamp each include a first connecting rod and two or more branch rods arranged at intervals. The upper end of the branch rod is fixedly connected to the lower end of the first connecting rod. The lower end of the branch rod is bent upward into a hook-shaped gripper. The first connecting rod of the first clamp is connected by a pin between any two branch rods of the second clamp. A material gripping space is formed between the branch rods of the first clamp and the second clamp. The upper ends of the first clamp and the second clamp are both fastened to the pull rope."

[0004] The aforementioned patent's method of controlling the clamping rod by pulling up or releasing the rope has poor stability. When the steel pipe is raised and lowered, the rope is at risk of displacement, which can cause the center of gravity to shift. This can easily lead to the clamping rod failing to grip and hold the building materials as expected. Therefore, this application proposes a simple building material handling clamp. Summary of the Invention

[0005] Based on this, it is necessary to provide a simple material handling clamp to address the above-mentioned technical problems. Through the overall structural design, the lifting guide frame can be controlled to move up and down, which facilitates the sliding of the connecting bolt inside the arc-shaped guide groove. This allows the first and second clamps to move stably with the support shaft as the axis. Combined with the material gripping space formed between the first and second clamps, it is easy to achieve stable gripping and clamping of building materials.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0011] In a preferred embodiment of the simple material handling clamp provided by this utility model, a top plate is fixed to the upper end of the base plate.

[0012] In a preferred embodiment of the simple building material handling clamp provided by this utility model, a screw is rotatably connected inside the top plate, and the lower end of the screw passes through the lifting guide frame and is threadedly connected to the lifting guide frame.

[0023] As described in the background art, the above-mentioned patent's method of controlling the clamping rod by pulling up or releasing the pull rope has poor stability. When the steel pipe is raised and lowered, there is a risk of displacement of the pull rope, which may cause the center of gravity to shift, and thus the clamping rod may not be able to grasp and clamp the building materials as expected.

[0024] To solve this technical problem, this utility model provides a simple material handling clamp, which is used for handling building materials during the construction process.

[0025] The system includes a substrate 1, with a support shaft 2 fixed at the lower end of the substrate 1. A first clamp 3 and a second clamp 4 are rotatably connected to the outer side of the support shaft 2. The second clamp 4 is located inside the first clamp 3. Connecting bolts 8 are fixed to the inner sides of the upper ends of both the first clamp 3 and the second clamp 4. Arc-shaped guide grooves 6 are symmetrically opened inside the substrate 1. Two connecting bolts 8 are located inside the two arc-shaped guide grooves 6 and are slidably connected to the arc-shaped guide grooves 6. A rotating shaft 9 is rotatably connected to one end of each of the two connecting bolts 8. A lifting guide frame 12 is provided on the outer side between the two rotating shafts 9. Both rotating shafts 9 are located inside the lifting guide frame 12 and are movably connected to the lifting guide frame 12. The outer side of the lifting guide frame 12 is in contact with the substrate 1.

[0026] The simple material handling clamp provided by this utility model, through the overall structural design, enables the first clamp 3 and the second clamp 4 to move in a stable tilting motion around the support shaft 2. Combined with the material gripping space formed between the first clamp 3 and the second clamp 4, it is convenient to achieve stable gripping and clamping of building materials.

[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] Example 1:

[0030] Please refer to Figure 1-3 A simple material handling clamp includes a base plate 1, a support shaft 2 fixed to the lower end of the base plate 1, and a first clamp 3 and a second clamp 4 rotatably connected to the outer side of the support shaft 2. The second clamp 4 is located inside the first clamp 3. Through the structural design of the first clamp 3 and the second clamp 4, a material gripping space is formed between the lower ends of the first clamp 3 and the second clamp 4. By driving the first clamp 3 and the second clamp 4 to tilt synchronously around the support shaft 2, the material gripping space facilitates the gripping and clamping of building materials, thus facilitating handling. To further improve the gripping and clamping effect of building materials, grippers 5 are fixed to the lower ends of both the first clamp 3 and the second clamp 4.

[0031] In order to stably drive the first clamp 3 and the second clamp 4 to tilt synchronously around the support shaft 2, the inner sides of the upper ends of the first clamp 3 and the second clamp 4 are fixed with connecting bolts 8. The interior of the base plate 1 is symmetrically provided with arc-shaped guide grooves 6. The two connecting bolts 8 are located inside the two arc-shaped guide grooves 6 and are slidably connected to the arc-shaped guide grooves 6. One end of each of the two connecting bolts 8 is rotatably connected to a rotating shaft 9. A lifting guide frame 12 is provided on the outer side between the two rotating shafts 9. The two rotating shafts 9 are located inside the lifting guide frame 12 and are movably connected to the lifting guide frame 12. The outer side of the lifting guide frame 12 is in contact with the base plate 1.

[0032] By controlling the lifting guide frame 12 to perform lifting and lowering movements, and utilizing the movable connection between the rotating shaft 9 and the lifting guide frame 12, along with the sliding connection between the connecting bolt 8 and the arc-shaped guide groove 6, the first clamp 3 and the second clamp 4 can be driven to perform synchronous tilting movements around the support shaft 2, and the stability of the first clamp 3 and the second clamp 4 during movement can be effectively improved. Specifically, a top plate 10 is fixed to the upper end of the base plate 1, and a screw 11 is rotatably connected inside the top plate 10. The lower end of the screw 11 passes through the lifting guide frame 12 and is threadedly connected to the lifting guide frame 12. A first spur gear 13 is fixed to the upper end of the screw 11. The first spur gear 13 is located at the upper end of the top plate 10. A reduction motor 14 is fixed inside the upper end of the base plate 1, and a second spur gear 15 is fixed to the output end of the reduction motor 14. The second spur gear 15 is meshed with the first spur gear 13.

[0033] The aforementioned geared motor 14 is electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.

[0034] Example 2:

[0035] The simple material handling clamp provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, in order to guide the sliding movement of the connecting bolt 8 and thus ensure the smoothness of the connecting bolt 8 sliding in the arc-shaped guide groove 6, two arc-shaped guide posts 7 are provided on the inner side of each arc-shaped guide groove 6. The arc-shaped guide posts 7 are fixed to the base plate 1, and the connecting bolt 8 is located outside the arc-shaped guide posts 7 and is slidably connected to the arc-shaped guide posts 7.

[0036] The simple material handling clamp provided by this utility model is used as follows: by controlling the reduction motor 14 to drive the second flat gear 15 to rotate, the meshing of the second flat gear 15 and the first flat gear 13 drives the screw 11 to rotate, and then through the threaded connection between the screw 11 and the lifting guide frame 12, and the movable connection between the rotating shaft 9 and the lifting guide frame 12, combined with the adhesion between the lifting guide frame 12 and the base plate 1, it is convenient to drive the lifting guide frame 12 to move up and down.

[0037] Furthermore, when the lifting guide frame 12 is raised or lowered, the rotating shaft 9 follows the lifting guide frame 12 in raising or lowering. At the same time, it slides and guides the connecting bolt 8 inside the arc-shaped guide groove 6, causing the rotating shaft 9 to move inside the lifting guide frame 12. This enables the first clamp 3 and the second clamp 4 to move synchronously with the support shaft 2 as the axis, thereby controlling the expansion and contraction of the material gripping space. The gripper 5 is used to easily grip and clamp building materials for transportation.
