[0045] The inventor provides a robot anti-collision structure suitable for the bogie lifting platform to solve the above technical defects
[0046] The utility model will be described in further detail in combination with the drawings:
[0047] As Figures 1-3The utility model provides a kind of robot anti-collision structure suitable for bogie lifting platform, the structure includes support 1, is equipped with transverse displacement adjusting device 2 on it;Anti-collision device 3 is connected with transverse displacement adjusting device 2, and is located at both ends of support 1;Limiting device 4 is installed on support 1, and is electrically connected with robot body 5, for detecting the position of transverse displacement adjusting device 2;Wherein, when robot body 5 travels, transverse displacement adjusting device 2 drives anti-collision device 3, and stretches or shrinks to the both sides of robot body 5.In the above structure, due to the arrangement of anti-collision device 3, robot body 5 can effectively avoid collision with surrounding obstacles or lifting platform structure during travel, so as to protect robot body 5 from damage, while also preventing damage to the surrounding environment or equipment.At the same time, through transverse displacement adjusting device 2, anti-collision device 3 can stretch or shrink to the both sides of robot body 5 according to actual needs, and this dynamic adjustment capability enables robot body 5 to operate flexibly in spaces of different widths, further improving the safety during operation;And, since anti-collision device 3 can stretch or shrink, this improves the versatility and flexibility of robot body 5.Finally, limiting device 4 is not only used for detecting the position of transverse displacement adjusting device 2, but also electrically connected with robot body 5, realizing accurate monitoring of the position of anti-collision device 3, which helps to ensure that anti-collision device 3 functions at the correct time and correct position, further improving the safety and accuracy of operation;In addition, effective anti-collision structure can significantly reduce the damage to robot body 5 caused by collision, thereby reducing the frequency of maintenance and replacement of parts and saving maintenance costs. Figures 1-3As shown, the lateral displacement adjusting device 2 includes a power output unit 201 and a guide assembly, the power output unit 201 is in transmission connection with the guide assembly, and the anti-collision device 3 cooperates with the guide assembly. The power output unit 201 serves as a driving force source, which can accurately control the extension and contraction degree of the anti-collision device 3. Through the transmission connection with the guide assembly, the anti-collision device 3 can move smoothly along the predetermined path, ensuring that the anti-collision device 3 always remains in the correct position during the movement of the robot body 5, providing effective anti-collision protection. Moreover, the quick response capability of the power output unit 201 during the movement of the robot body 5 enables the anti-collision device 3 to quickly extend or contract according to the movement state of the robot body 5. In an emergency, this quick response can greatly shorten the reaction time of the anti-collision device 3, thereby reducing the risk of collision. The guide assembly not only provides a stable moving track for the anti-collision device 3, but also enhances the structural stability of the entire lateral displacement adjusting device 2 through the transmission connection with the power output unit 201, reducing the risk of deviation or failure of the anti-collision device 3 caused by external interference or vibration, and improving the reliability of the anti-collision structure. At the same time, due to the flexible design of the power output unit 201 and the guide assembly, the extension and contraction range of the anti-collision device 3 can be adjusted according to the actual working environment, which improves the adaptability and versatility of the robot body 5. Through accurate control of the position and quick response capability of the anti-collision device 3, the lateral displacement adjusting device 2 helps to reduce the pause and waiting time of the robot body 5 during the operation process, effectively protecting and reducing the downtime caused by collision, thereby improving the overall operation efficiency. For example Figures 1-3As shown, further, the power output unit 201 is preferably an electric motor, and the end of the power output unit 201 is sleeved with a transmission unit 203, and the guide assembly includes rotating units 202 and sliders 204; the rotating units 202 are provided in two, and the two rotating units 202 are arranged at intervals, and each rotating unit 202 is provided with a slider 204, and the anti-collision device 3 is arranged at the bottom of the slider 204; the end of the transmission unit 203 is sleeved between the two rotating units 202; wherein, under the drive of the power output unit 201, the transmission unit 203 drives the two rotating units 202 to rotate, so as to make the two sliders 204 move away from or close to each other. In this process, the motor as the power output unit 201 provides a stable and adjustable power source, and through the transmission unit 203, the rotary motion of the motor can be efficiently transmitted to the rotating units 202, thereby driving the sliders 204 and the anti-collision device 3 to expand or contract, ensuring the stability and efficiency of power transmission. The interval arrangement of the two rotating units 202 and their connection mode with the transmission unit 203 enable the two sliders 204 to accurately move away from or close to each other under the drive of the motor, and this precise control capability is crucial for adjusting the position of the anti-collision device 3 in spaces of different widths, ensuring the effectiveness and accuracy of anti-collision protection. The design of the rotating units 202 and the sliders 204 not only realizes the displacement of the anti-collision device 3, but also enhances the rigidity and stability of the entire structure, which helps to resist external impact and vibration, maintains the stability and reliability of the anti-collision device 3 during operation. Finally, the modular design of the motor, the transmission unit 203, the rotating units 202 and the sliders 204 simplifies the maintenance and replacement process of the entire anti-collision structure, and when a fault occurs or needs to be upgraded, the relevant components can be quickly located and replaced, reducing maintenance costs and time costs. As can be seen from the figure, the two rotating units 202 are axially coincident, the rotating units 202 are lead screws, the rotating units 202 are screwed with the sliders 204, and the transmission unit 203 is a transmission belt (not shown in the figure). The lead screw as the rotating unit 202 can provide accurate linear displacement, when the motor drives the transmission belt to rotate, the belt drives the two lead screws to rotate synchronously, and then drives the sliders 204 and the anti-collision device 3 to accurately expand or contract along the lead screw axis through screwing, ensuring that the anti-collision device 3 can accurately reach the predetermined position and provide effective anti-collision protection. The transmission belt is used as the transmission unit 203, which has the characteristics of smooth transmission, low noise and high efficiency, and can effectively transmit the power of the motor to the two lead screws, realizing the rapid response and accurate control of the anti-collision device 3. At the same time, the flexible nature of the belt can also absorb part of the vibration and impact, improving the stability and reliability of the entire anti-collision structure. The screw connection between the lead screw and the slider 204 simplifies the complexity of the entire anti-collision structure, and this connection method is easy to install and disassemble, facilitating the maintenance and replacement of the anti-collision device 3 or related components.Meanwhile, the screw rod and the transmission belt also reduce additional potential failure points, reducing maintenance costs and time costs; and the screw rod is used as the rotating unit 202, which has a large load capacity and can withstand the large force and torque generated by the anti-collision device 3 during extension or contraction, ensuring the stability and safety of the anti-collision structure.
[0048] Further, as shown in Figures 1-3 The anti-collision device 3 includes a mounting plate 301 mounted on both ends of the lateral displacement adjusting device 2; the bottom of the mounting plate 301 is provided with a buffer unit 302, and the end of the buffer unit 302 is provided with an anti-collision wheel 303; specifically, the mounting plate 301 is axially coincident with the lateral displacement adjusting device 2, the anti-collision wheel 303 is axially perpendicular between the mounting plate 301 and the buffer unit 302, and the buffer unit 302 is a spring. In the application process, the anti-collision wheel 303, as a component directly contacting the external obstacles, can effectively disperse and absorb the impact force during the collision, protecting the robot body 5 and the surrounding equipment from damage; at the same time, its axial perpendicular design makes the anti-collision wheel 303 more stably withstand and disperse the impact force during the collision, improving the anti-collision effect. The spring, as the buffer unit 302, has good elasticity and buffering capacity, and can absorb part of the impact force and slow down the severity of the collision through its elastic deformation when the collision occurs, thereby protecting the robot body 5 and the obstacles from serious damage. In addition, the buffering effect of the spring can also reduce the noise and vibration generated by the collision. The axial coincidence design of the mounting plate 301 and the lateral displacement adjusting device 2 enables the anti-collision device 3 to accurately adjust its position with the extension or contraction of the lateral displacement adjusting device 2, ensuring that the anti-collision device 3 can be accurately aligned and protecting the edges or corners of the bogie lifting platform, improving the accuracy and effectiveness of the anti-collision protection. The mounting plate 301, as the main supporting structure of the anti-collision device 3, its stability and rigidity are crucial to the performance of the entire anti-collision structure, through the close connection with the lateral displacement adjusting device 2 and the axial coincidence design, the mounting plate 301 can obtain stable support and power transmission, ensuring the stability and reliability of the anti-collision device 3 during operation. As shown in Figure 4 In the application, the support 1 includes a support rod 101 and a fixed rod 102, the support rod 101 is provided with two groups, each group of the support rod 101 has two, the two groups of the support rod 101 are symmetrically installed on the opposite ends of the fixed rod 102, the power output unit 201 is installed on the top of the fixed rod 102, and the two rotating units 202 are installed inside the fixed rod 102; the front and rear ends of the robot body 5 are provided with mounting openings 6, the mounting openings 6 on each end are symmetrically arranged and communicate with each other, the anti-collision structure is installed in the mounting openings 6, and in the process of advancing of the robot body 5, the lateral displacement adjusting device 2 drives the anti-collision device 3 to extend out of the mounting openings 6 for anti-collision, or drives the anti-collision device 3 to retract into the mounting openings 6.
