Description

Technical Field

[0001] This invention relates to the field of high-efficiency special-purpose vehicles, specifically multi-functional high-efficiency special-purpose vehicles. Background Technology

[0002] In engineering operations, material handling, and facility maintenance, traditional high-efficiency special-purpose vehicles have long been used in open-field operations due to their efficient operation capabilities in single work scenarios, facilitating the advancement of various projects. However, with the increasing sophistication of urban construction, the deepening of underground space development, and the growing demand for special-scenario operations, operations in confined spaces (such as narrow alleys in old urban residential areas, mine tunnels, underground utility tunnels, narrow warehouse passages, and small foundation pits) are becoming increasingly frequent. The inherent structural defects of traditional high-efficiency special-purpose vehicles make them difficult to use normally in such scenarios, becoming a core bottleneck that limits their application scope and restricts the improvement of efficiency in confined space operations.

[0003] Traditional high-efficiency special vehicles are usually fixed in size and too large, which makes it difficult for them to pass through smoothly or even enter the work area. This makes them inconvenient to use in narrow spaces. In addition, high-efficiency special vehicles are mostly designed for a single function. If multiple operations such as clamping and transferring need to be completed in a narrow space, multiple different devices need to be brought in alternately. Frequent changes can easily cause congestion in narrow spaces, and the size differences between different devices further increase the difficulty of operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-functional and efficient special-purpose vehicle, which solves the core problems of traditional high-efficiency special-purpose vehicles, such as their excessive width, inability to adapt to narrow passages, and the inability to perform multiple operations such as clamping and transporting in narrow spaces.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multi-functional and high-efficiency special vehicle includes a support frame. A clamping mechanism is fixedly connected to the front end of the upper surface of the support frame. The clamping mechanism includes a mounting frame. A servo motor is fixedly connected to the front end of the upper surface of the support frame. The output end of the servo motor is fixedly connected to the lower end of the mounting frame. A servo motor is fixedly connected to two sides of the outer wall of the mounting frame, respectively. A rotating rod is fixedly connected to the output end of the servo motor. A support plate is fixedly connected to the middle of the bottom surface of the mounting frame. A rotating connecting rod is rotatably connected to one side of the outer wall of the support plate. A placement plate is rotatably connected to the front end of the rotating connecting rod. A rotating connecting rod is rotatably connected to the middle of the bottom surface of the placement plate. A servo motor is fixedly connected to the middle of the upper surface of the placement plate. The output end of the servo motor is fixedly connected to the upper end of the rotating connecting rod. Clamping arms are engaged and rotated on both sides of the front end of the bottom and top surfaces of the placement plate. A rotating plate is fixedly connected to the output end of the servo motor. A rotating rod is rotatably connected to the other side of the rotating plate. The lower end of the support frame is fixedly connected to a base plate. Rotating arms are rotatably connected to the four corners of the upper surface of the base plate. Teeth are fixedly connected to the outer walls of the rotating arms. Rotating rollers are fixedly connected to the upper ends of the rotating arms. A rotary motor is fixedly connected to the top of the support frame. The rotary motor is fixedly connected to the rear rotating roller. A transmission wheel is fixedly sleeved on the outer wall of the rotating roller. A chain is meshed with the outer wall of the transmission wheel. Each of the rotating arms has a storage cavity inside. A driven gear is rotatably connected to the middle of the top surface of the storage cavity. The lower end of the driven gear passes through the storage cavity and is fixedly connected to a housing. A movable wheel is rotatably connected to the lower end of the housing. A second rotary motor is fixedly connected to the side of the storage cavity near the top surface of the driven gear. A driving gear is fixedly connected to the output end of the second rotary motor. Fixing frames are fixedly connected to the outer walls of the opposite sides of the housing on both front sides. A third rotary motor is fixedly connected to the surface of the fixing frames. The output end of the third rotary motor is fixedly connected to the rotation shaft of the front movable wheel. Through the above technical solution, the clamping mechanism driven by multiple servo motors enables flexible and precise adjustment of clamping posture, angle, and position. Combined with the placement frame, it can clamp and transfer items. The synchronous drive structure of four sets of rotating arms using tooth meshing and chain transmission can effectively reduce the overall width of the special vehicle and reasonably increase its length, avoiding the problem of being too wide to enter narrow passages, and greatly improving the adaptability of passage in narrow spaces. Combined with the arrangement of independent steering and driving of the moving wheels, it further enhances the steering flexibility, enabling it to easily complete passage, steering, and positioning operations in narrow spaces.

[0006] Furthermore, a placement frame is fixedly connected to the rear end of the upper surface of the support frame; The above technical solution allows for the storage and transfer of materials during operation using a placement frame, thus integrating clamping operations with material carrying.

Through the above technical solution, by linking rotating rod one with rotating connecting rod one, rotating connecting rod two with clamping arm, rotating plate with rotating connecting rod one and rotating connecting rod three, and rotating connecting rod three with placement plate, the moving parts of the clamping mechanism can form a stable multi-link coordinated transmission, and achieve precise adjustment of the posture, angle and position of placement plate and clamping arm.

[0008] Furthermore, the teeth on both sides mesh with each other; Through the above technical solution, the teeth on the outer walls of the two rotating arms mesh with each other, enabling the four sets of rotating arms to operate at synchronized angles during transmission.

[0009] Furthermore, a tension spring is fixedly connected to the rear end of the bottom surface of the support frame, and a tension roller is fixedly connected to the front end of the tension spring, with the tension roller abutting against the outer wall of the chain; Through the above technical solution, the elastic force of the tension spring automatically compensates for the slack of the chain, always maintaining a tight mesh between the chain and the drive wheel, effectively preventing chain malfunctions such as loosening, skipping teeth, and slippage.
