Description

Technical Field

[0001] This utility model relates to the field of construction material handling, and in particular to a construction site robot grasping mechanism. Background Technology

[0002] A gripping mechanism generally refers to a mechanical structure or device with gripping capabilities, widely used in industrial manufacturing, logistics and transportation, and automated production. Its core function is to use components such as robotic arms, grippers, and suction cups to grasp, transport, and place objects, replacing manual labor in repetitive, heavy, or dangerous tasks, thereby improving production efficiency and operational safety. The gripping mechanism of a construction site robot is a mechanical device specifically designed for construction scenarios, used to grasp, transport, and stack various materials on the construction site, or to assist in completing specific construction operations. Its design must adapt to the complex environment of the construction site, the diversity of materials, and the demands of high-intensity operations. Some gripping mechanisms have replaced manual operation to a certain extent, but they generally suffer from simple structure and limited function. They mostly use fixed clamping methods and cannot be flexibly adjusted according to the size and shape of materials. When faced with diverse building materials such as bricks, steel bars, and boards, they often experience problems such as unstable clamping and gripping failure. They are difficult to adapt to the complex and ever-changing material stacking environment on construction sites, especially in scenarios with narrow spaces and messy material stacking, which greatly reduces work efficiency. Some gripping mechanisms are inefficient, increasing safety risks when handling heavy or irregularly shaped materials. Early mechanical gripping devices, while capable of handling certain tasks, lacked flexibility and precision, making them unsuitable for the complex and varied material stacking environment and diverse material shapes and sizes on construction sites. Therefore, a construction site robot gripping mechanism is proposed to address these issues. Utility Model Content

[0005] This utility model has the following beneficial effects: 1. In this utility model, when the construction site robot gripping mechanism is working, the cylinder one runs and drives the connecting shaft to slide, which in turn causes the connecting plate and connecting column one to rotate. The connecting ring and connecting block slide accordingly, driving the rotating rod one to rotate, causing the rotating block to rotate, and driving the rotating rod two to rotate on the support block two, realizing the rapid opening and closing of gripping materials. The rapid opening and closing design greatly improves gripping efficiency, transmits power, and the gripping force is controllable.

[0006] 2. In this utility model, when cylinder two starts operating, its drive end drives the telescopic rod to extend and retract, thereby causing support block three to slide. The sliding of support block three drives rotating rod three to rotate around the connection point.

[0009] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0010] Example: A construction site robot gripping mechanism, referring to Figures 1 to 3 The mechanism includes a support frame 1, which serves as the basic framework for the entire gripping mechanism, providing mounting support points, bearing various forces generated during gripping operations, and maintaining the overall stability of the mechanism. A clamping mechanism 2 and an adjusting mechanism 3 are fixedly connected externally to the support frame 1. The clamping mechanism 2 includes a drive assembly 22 for driving. A support block 21 is fixedly connected externally to the drive assembly 22, providing a stable mounting base to ensure no displacement or shaking occurs. A connecting plate 23 is fixedly connected externally to the drive assembly 22, externally fixed to the support block 21, and slidably connected to the outside of the support frame 1. Multiple connecting posts 25 are fixedly connected externally to the connecting plate 23, with their bottoms fixedly connected to a connecting ring 24, and externally slidably connected to the outside of the support frame 1. Driven by the connecting plate 23, these posts slide along the support frame 1, thereby driving the connecting ring 24 to move, and simultaneously controlling the direction of movement of the connecting ring 24. The connecting ring 24 is fixedly connected to the bottom of the connecting column 25. Multiple connecting blocks 26 are fixedly connected inside the connecting ring 24 and slidably connected to the outside of the support frame 1. When the connecting ring 24 slides, the power is converted from linear motion to rotational motion. The connecting block 26 is rotatably connected to the outside of the connecting rod 27. One end is rotatably connected to the connecting block 26 and rotatably connected to the rotating block 2010. Rotating under the drive of the connecting block 26, the connecting rod 27 transmits the sliding power of the connecting block 26. It is an important intermediate component for force transmission. The rotating block 2010 is rotatably connected to the outside of the rotating rod 27. Rotating outside the support frame 1, the rotating block 2010 is rotatably connected to the rotating rod 27. Rotating under the drive of the rotating rod 27, the rotating block 2010 plays the role of force direction and transmission, changing the direction of force transmission, so that the power can be effectively transmitted to the rotating rod 29. Specifically, the drive component 22 operates, causing the connecting plate 23 fixed thereto to slide on the support frame 1. The connecting plate 23 causes multiple connecting columns 25 to slide along the support frame 1. The connecting columns 25 cause the bottom connecting ring 24 to move synchronously. The connecting ring 24 drives multiple internal connecting blocks 26 to slide on the support frame 1. The connecting blocks 26 cause the rotating rod 27 to rotate. The rotating rod 27 transmits power to the rotating block 2010, causing it to rotate on the support frame 1. The rotating block 2010 then drives the rotating rod 29 to complete the opening and closing of the gripping action. The gripping response is rapid, improving work efficiency, making the gripping force distribution uniform, and enhancing gripping stability. The sliding and rotating cooperation of each component can adapt to the gripping needs of materials of different sizes, improving the versatility of the mechanism, and can withstand greater gripping force, thus extending the service life of the equipment.

[0011] Rotating rod 29 is rotatably connected to the outside of rotating block 2010, and is rotatably connected to rotating block 2010. The other end is rotatably connected to support block 28. Under the drive of rotating block 2010, it rotates around support block 28 to realize the opening and closing of the gripping action. It is one of the components that directly executes the gripping action. Support block 28 is rotatably connected to the outside of rotating rod 29, providing a rotation support point for rotating rod 29 and fixing one end of rotating rod 29 so that rotating rod 29 can rotate stably with it as the fulcrum. The drive assembly 22 includes cylinder 221, which is the power source of gripping mechanism 2. It receives control signals and provides initial power for the entire gripping action. The drive end of cylinder 221 is fixedly connected to connecting shaft 222. The drive end of cylinder 221 is fixedly connected and fixed inside connecting plate 23. The components serve to transmit power. The external of cylinder 221 is fixedly connected to the inside of support block 21, and the external of connecting shaft 222 is fixedly connected to the inside of connecting plate 23. The extension and retraction of cylinder 221 is transmitted to connecting plate 23 through connecting shaft 222. At the same time, connecting shaft 222 slides outside of support frame 1 to ensure the stability of power transmission. The external of connecting shaft 222 is slidably connected to the outside of support frame 1. The external of connecting column 25 is slidably connected to the outside of support frame 1. The external of connecting block 26 is slidably connected to the outside of support frame 1. The external of connecting plate 23 is slidably connected to the outside of support frame 1. The external of rotating rod 27 and rotating rod 29 is rotatably connected to the outside of support frame 1. The external of rotating block 2010 is rotatably connected to the outside of support frame 1. Specifically, cylinder 221, acting as a power source, receives a signal and starts, driving the connecting shaft 222 to slide. The connecting shaft 222 transmits power to the connecting plate 23, causing it to slide along the support frame 1. The connecting plate 23 drives the connecting column 25 to slide, which in turn drives the connecting ring 24, causing the connecting block 26 to slide synchronously. The connecting block 26 drives the rotating rod 27 to rotate, which in turn causes the rotating block 2010 to rotate, thereby driving the rotating rod 29 to rotate around the support block 28. This achieves the opening and closing of the gripping action, resulting in rapid gripping response, improved work efficiency, stable gripping force, reduced risk of material falling, enhanced gripping balance, adaptability to materials of different sizes, compact structure to adapt to complex construction site environments, and extended equipment service life.

The connecting column 32 is fixedly connected to the outside of the support plate 31, with one end fixed to the outside of the support plate 31 to ensure its normal operation. A cylinder 33 is fixedly connected to the outside of the connecting column 32, serving as the power source for the adjusting mechanism 3. It extends and retracts its drive end by receiving control signals, providing power to adjust the angle of the clamping mechanism 2, converting pneumatic energy into mechanical energy. A telescopic rod 34 is fixedly connected to the drive end of the cylinder 33, with one end fixedly connected to the drive end of the cylinder 33 and the other end fixedly connected to the support block 35, transmitting the power of the cylinder 33 to push or pull the support block 35. It is the direct component for power transmission. The telescopic rod 34... The external fixed connection is a support block 35, and the inner side is rotatably connected to the rotating rod 36. It moves under the drive of the telescopic rod 34. The inner side of the support block 35 is rotatably connected to the rotating rod 36, one end of which is rotatably connected to the support block 35, and the other end is rotatably connected to the support plate 27. It rotates under the drive of the support block 35, pushing or pulling the support plate 27 to realize the angle adjustment of the clamping mechanism 2. The external rotatable connection of the rotating rod 36 is the support plate 27, which is externally fixedly connected to the outside of the support block 1. It moves under the drive of the rotating rod 36 to realize the angle adjustment of the clamping mechanism 2. The external fixed connection of the support plate 27 is to the outside of the support block 1. The external fixed connection of the support frame 1 is a solar panel 4, which can convert solar energy into electrical energy and provide power support. Specifically, cylinder 221, acting as a power source, receives a signal and starts, driving the connecting shaft 222 to slide. The connecting shaft 222 transmits power to the connecting plate 23, causing it to slide along the support frame 1. The connecting plate 23 drives the connecting column 25 to slide, which in turn drives the connecting ring 24, causing the connecting block 26 to slide synchronously. The connecting block 26 drives the rotating rod 27 to rotate, which in turn causes the rotating block 2010 to rotate, thereby driving the rotating rod 29 to rotate around the support block 28, thus realizing the opening and closing of the gripping action. Each component is slidably or rotatably connected to the support frame 1, ensuring stable gripping force and reducing the risk of material falling. Multiple sets of connecting columns and connecting blocks 26 work together to enhance gripping balance and adapt to materials of different sizes.

[0013] The implementation principle of this application embodiment is as follows: When it is necessary to grasp materials, the operation of cylinder 221 drives the sliding of connecting shaft 222, thereby driving the rotation of connecting plate 23 and connecting column 25, thereby driving the sliding of connecting ring 24 and connecting block 26, thereby driving the rotation of rotating rod 27, thereby driving the rotation of rotating block 2010, thereby driving rotating rod 29 to rotate on support block 28, thereby achieving the effect of quickly opening and closing to grasp materials.

[0014] When it is necessary to adjust the position of the clamping mechanism 2, the operation of cylinder 2 33 drives the sliding of telescopic rod 34 and support block 35, thereby driving the rotation of rotating rod 36, which in turn drives the rotation of support plate 2 37 and support block 1 21, thus achieving the effect of quickly adjusting the position of the clamping mechanism 2.
