[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0020] During the replacement of the guide rod in a chain conveyor, the guide rod itself has a certain weight (especially the guide rod with a larger diameter). If it is not fixed during disassembly, it may move downwards due to gravity. The movement of the guide rod may not only damage the chain, sprocket, or other related components, causing equipment failure, but also make the disassembly work more difficult, requiring additional tools and time to complete. It may also cause injury to the workers, especially since the guide rod may suddenly fall if it is not properly fixed. Therefore, it is necessary to fix the guide rod to be replaced during the replacement process. The commonly used tool for fixing the guide rod in the prior art is the clamping assembly 2. The clamping assembly 2 mainly includes a first clamping part 5 and a second clamping part 6. When using it, first fix the entire clamping assembly 2 to the support frame 1, and then fix the support frame 1 to the conveyor frame 17 with a special locking tool, such as bolts, pins, buckles, etc., to maintain the stability of the entire clamping assembly 2. Then, firstly, attach the first clamping part 5 to one side of the guide rod, and then use bolts to fix the first clamping part 5 and the second clamping part 6 together.

[0021] As can be seen from the above, the existing conveyor rod replacement device has the following defects when in use: when using the clamping component 2 in the prior art to fix the rod, it is necessary to manually fix the first clamping part 5 and the second clamping part 6 to achieve the positioning of the rod. If there are many rods to be replaced, before each rod replacement, it is necessary not only to manually fix the clamping component 2 to the conveyor frame, but also to manually fix the rod and the entire clamping component 2, which increases the labor of the workers and reduces the efficiency of rod replacement. Based on the above problems, the present invention adopts the following improvement method to solve them.

[0022] like Figures 1-6As shown, the conveyor rod replacement device differs from existing technologies in that the clamping assembly 2 of this invention mainly includes a first clamping member 5 driven by a first driving member 3 and a second clamping member 6 driven by a second driving member 7. A first distance sensor 4 is installed on the side of the first clamping member 5 away from the first driving member 3. This first distance sensor 4 is used to monitor the distance between the first clamping member 5 and the rod to be replaced. Simultaneously, a second distance sensor 8 is installed on the side of the second clamping member 6 away from the second driving member 7. This second distance sensor 8 is used to monitor the distance between the second clamping member 6 and the rod to be replaced. (The first distance sensor 4 and the second distance sensor 8 can be ultrasonic distance sensors). The output terminals of the first distance sensor 4 and the second distance sensor 8 are connected to the signal input terminal of a controller 9 mounted on a support frame 1, for providing the controller 9 with signals from the first clamping member 5. The controller 9 outputs a control signal to control the operation of the first drive member 3 and the second drive member 7. Specifically, when the first distance sensor 4 detects a horizontal distance of 10 cm between the first clamping member 5 and the rod, the controller 9 controls the first drive member 3 to move 10.05 cm; when the second distance sensor 8 detects a horizontal distance of 5 cm between the second clamping member 6 and the rod, the controller 9 controls the second drive member 7 to move 5.05 cm, so that the first clamping member 5 and the second clamping member 6 can fit tightly against both sides of the rod, achieving a firm fixation of the rod by the first clamping member 5 and the second clamping member 6. To increase the friction between the rod and the first clamping member 5 and the second clamping member 6, anti-slip pads 13 are installed on the outer surfaces of both the first clamping member 5 and the second clamping member 6. Figure 2As shown, to facilitate the insertion of the first clamping member 5 and the second clamping member 6 into the space between two adjacent through rods, both the first clamping member 5 and the second clamping member 6 are 7-shaped. An anti-slip pad 13 is installed on the surface of the clamping member, and is flat. The anti-slip pad 13 can be made of rubber or silicone. A monitoring port 14 is opened on the anti-slip pad 13, which is precisely aligned with the monitoring head of the distance sensor to avoid affecting the normal operation of the distance sensor. The size of the monitoring port 14 is smaller than the size of the entire distance sensor to prevent damage to the distance sensor when fixing the through rod. Based on the above, since the distance sensor is installed inside the clamping member, and its monitoring head is on the same plane as the side wall of the clamping member, the thickness of the anti-slip pad 13 can be set to 1 cm. When the distance sensor detects the clamping member extending into the through rod... When the horizontal distance between the rods is 10 cm, the actual horizontal distance between the clamping component (clamping component + anti-slip pad 13) and the through rod is 9 cm. The controller 9 controls the drive component to move 10.05 cm. Because the anti-slip pad 13 is elastic, it can buffer the external force applied to the through rod by the first drive component 3 and the second drive component 7 while increasing the friction. In addition, the support frame 1 is set in an inverted U-shape, and the width of the support frame 1 is greater than the width of the conveyor. Threaded rods 15 with anti-slip blocks 16 are symmetrically threaded on both sides of the support frame 1. In use, the handle at the end of the threaded rod 15 is rotated to bring the threaded rod 15 closer to the conveyor frame 17 until the anti-slip blocks 16 are tightly attached to the conveyor frame 17, thereby fixing the support frame 1 to the conveyor and improving the stability of the clamping assembly 2.

[0023] Furthermore, such as Figures 4-5As shown, to further enhance the convenience of the rod fixing process, a third driving component 10 is installed between the support frame 1 and the clamping assembly 2. In this invention, the first driving component 3, the second driving component 7, and the third driving component 10 are preferably driven by hydraulic cylinders. Of course, other driving devices, such as motors and lead screws, can also be used, as long as they can achieve stable and precise movement of the clamping assembly 2. A support plate 11 for connecting the first driving component 3 and the second driving component 7 is installed at the bottom of the third driving component 10. When the third driving component 10 operates, it can drive the entire clamping assembly 2 to move. Simultaneously, a third ranging sensor 12 (the second ranging sensor 8 can be an ultrasonic ranging sensor) is installed at the bottom of the support plate 11. This third ranging sensor 12 is used to monitor the support plate 11. The direct distance between the third ranging sensor 12 and the first ranging sensor 4 or the second ranging sensor 8 is pre-set in the controller 9. For example, if the distance between the monitoring heads of the third ranging sensor 12 and the first ranging sensor 4 is fixed at 20 cm, when the third ranging sensor 12 detects that the distance between the support plate 11 and the rod is 25 cm, the diameter of the rod is 6 cm. The controller 9 controls the third driving component 10 to move downward by 8 cm, which drives the entire clamping assembly 2 to move downward by 8 cm, so that the first ranging sensor 4 and the second ranging sensor 8 are exactly aligned with the center line of the rod. This helps the first clamping component 5 and the second clamping component 6 to accurately and firmly clamp and fix the rod, preventing it from falling off during the disassembly of the rod.

[0024] Furthermore, to further enhance the safety of workers during the replacement of the threaded rod, the controller 9 is electrically connected to the power supply of the chain conveyor. When the controller 9 controls the first drive component 3, the second drive component 7, or the third drive component 10 to run, it indicates that the worker is replacing the threaded rod. If the conveyor starts unexpectedly, for example, if another worker accidentally touches the power supply of the conveyor, the controller 9 can cut off the power supply of the conveyor in time to avoid safety hazards caused by the operation of the conveyor during the replacement process.
