Detailed Implementation
[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 A displacement-resistant seismic source weight guiding and buffering device includes a fixed frame 1. A guide cylinder 2 is installed on the inner side wall of the fixed frame 1 via a support block. A weight body 3 is disposed inside the guide cylinder 2. A traction rope is disposed at the upper end of the weight body 3 and is slidably connected to the fixed frame 1. A fixed plate 4 is fixedly connected to the surface of the guide cylinder 2.

An end plate 8 is fixedly connected to the other end of the telescopic rod 5 and a spring 9 is disposed on the outer side of the telescopic rod 5.
[0022] Please see Figure 1 , Figure 2 , Figure 4Multiple protrusions 7 are provided and evenly distributed on the connecting plate 6. The protrusions 7 can be used to guide the movement of the hammer body 3. One end of the spring 9 is fixedly connected to the end plate 8, and the other end of the spring 9 is fixedly connected to the fixing plate 4. The spring 9 can be used to connect the end plate 8. The inner wall of the fixing plate 4 is slidably connected to the guide rod 10, which is slidably connected to the guide cylinder 2 and fixedly connected to the connecting plate 6. The guide rod 10 can be used to guide the movement of the connecting plate 6.
[0023] Please see Figure 1 , Figure 2 , Figure 3 A buffer mechanism 11 is provided on the fixed frame 1. The buffer mechanism 11 includes a telescopic column 110. The telescopic column 110 is slidably connected to the horizontal part of the fixed frame 1. A contact plate 111 is fixedly connected to the lower end of the telescopic column 110. The contact plate 111 is slidably connected to the traction rope. The contact plate 111 is located directly above the counterweight body 3. A spring 112 is provided on the outer side of the telescopic column 110. A slider 113 is fixedly connected to the side of the contact plate 111. The slider 113 is slidably connected to the vertical part of the fixed frame 1. A damping hole 114 is provided in the vertical part of the fixed frame 1. A mounting plate 115 is fixedly connected to the end face of the slider 113. A telescopic extension is slidably connected to the inner wall of the mounting plate 115. The telescopic frame 116 has a damping ball 117 fixedly connected to its rod. The damping ball 117 is slidably connected to the damping hole 114. A spring 118 is provided on the outside of the rod of the telescopic frame 116. One end of the spring 118 is fixedly connected to the end of the telescopic frame 116, and the other end of the spring 118 is fixedly connected to the mounting plate 115. Through the setting of the spring 112 and the contact plate 111, the reverse impact force generated on the counterweight body 3 can be released and buffered. Under the action of the damping hole 114, the damping ball 117 and other structures, the excess deformation stress generated by the spring 112 can be worn away, avoiding the problem of excessive vibration of the spring 112.
[0024] Please see Figure 1 , Figure 2 , Figure 3 One end of the second spring 112 is fixedly connected to the top inner side of the fixed frame 1, and the other end of the second spring 112 is fixedly connected to the contact plate 111. The contact plate 111 can be connected and used through the setting of the second spring 112. Multiple damping holes 114 are provided and are evenly distributed on the fixed frame 1. The damping holes 114 can be used in conjunction with the damping ball 117 for wear.
[0025] Working principle: During use, the hammer body 3 can be released by the traction rope, allowing the hammer body 3 to move downward along the inside of the guide cylinder 2 and to contact and impact the ground. When the hammer body 3 moves, the protrusion 7 can slide along the surface of the hammer body 3 to guide it. When the hammer body 3 moves upward due to the shock, it can squeeze the protrusion 7. Under the deformation of the spring 9, the telescopic rod 5 can be pulled to move, so that the connecting plate 6 drives the protrusion 7 to always be in contact with the hammer body 3 to ensure a good guiding effect and avoid the problem of the hammer body 3 deviating.
[0026] When the counterweight body 3 contacts the contact plate 111, under the impact of the force, the contact plate 111 can be pushed to drive the telescopic column 110 to slide along the inner wall of the fixed frame 1, causing the spring 112 to deform, releasing and buffering the counter-vibration impact force. Furthermore, when the contact plate 111 moves, it can drive the slider 113 to move, thereby driving the mounting plate 115 to move, and then the telescopic frame 116 to move, ultimately driving the damping ball 117 to move within the damping hole 114. Under the pressure, the damping ball 117 can be moved, causing the spring 118 to deform. Eventually, the damping ball 117 is disengaged from the damping hole 114. Under the action of force, the damping ball 117 slides along the surface of the fixed frame 1. When the damping ball 117 slides into the next damping hole 114, the spring 118 recovers its deformation. This process repeats continuously. Under the action of the damping ball 117, the damping hole 114 and other structures, the excess deformation stress generated by the spring 112 can be worn away.
