[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Reference Figure 1 Figure 1 [As shown in the figure], an embodiment provided by the utility model: a ramming hammer for pipeline replacement, including an outer cylinder 6, an impact sleeve 1 is arranged at the left end of the outer cylinder 6, the impact sleeve 1 penetrates through the left side of the outer cylinder 6, a front joint 2 is arranged on the right side of the impact sleeve 1, a male joint 3 is fixedly connected to the left inner wall of the outer cylinder 6, the male joint 3 is fixedly connected to the front joint 2, a front section of the impact hammer 4 is fixedly connected to the middle of the left inner wall of the outer cylinder 6, a rear section of the impact hammer 5 is fixedly connected to the middle of the inner wall of the outer cylinder 6, pistons 7 are fixedly connected to the middle of the inner wall of the outer cylinder 6, piston shock pads 8 are fixedly connected to the bottoms of the pistons 7, a gas distribution rod 9 is fixedly connected to the middle of the right inner wall of the outer cylinder 6, shock pads 10 are fixedly connected to the right sides of the inner wall of the outer cylinder 6, and female joints 11 are arranged on the right outer sides of the outer cylinder 6;
[0021] Specifically, compressed air enters the outer cylinder 6 through the female joint 11 to provide power for the equipment. For the strike of the impact hammer, the gas distribution rod 9 is driven by the compressed air, so that the front section of the impact hammer 4 and the rear section of the impact hammer 5 move in the outer cylinder 6. The piston shock pads 8 at the bottom for shock absorption and stability and the shock pads 10 on the right side of the outer cylinder 6 reduce the vibration generated during the movement of the impact hammer. The impact force is transmitted to the anvil through the connection between the front joint 2 and the male joint 3. The anvil is connected by a pull rod, and the strike of the anvil enables effective replacement of the pipeline.
[0022] Reference Figure 1 Figure 1 [As shown in the figure], centering rings 12 are fixedly connected to the right outer walls of the outer cylinder 6, compression springs 14 are fixedly connected to the outer sides of the centering rings 12, the other ends of the compression springs 14 are fixedly connected to limit pins 13, one-way seals 15 are fixedly connected to the middle of the inner part of the outer cylinder 6, and two-way seals 16 are fixedly connected to the left tops of the one-way seals 15;
[0023] Specifically, the centering rings 12 and the compression springs 14 are arranged so that the equipment can maintain the central position in the pipeline during operation. The compression springs 14 can provide a certain supporting force inside the outer cylinder 6 to prevent the ramming hammer from moving unstably in the pipeline. The limit pins 13 ensure that the position of the ramming hammer does not move excessively during the operation. The one-way seals 15 and the two-way seals 16 are used for sealing to ensure that the gas and impact force inside the outer cylinder 6 do not leak, and at the same time reduce friction to ensure the stable strike of the impact hammer.
[0024] Reference Figure 1 Figure 1 [As shown in the figure], O-rings 17 are fixedly connected to the left ends of the inner walls of the outer cylinder 6, stepped seals 18 are fixedly connected to the left sides of the O-rings 17, elastic dowel pins 19 are fixedly connected to the inner wall of the impact sleeve 1, and elastic dowel pins 20 are fixedly connected to the bottoms of the elastic dowel pins 19;
[0025] Specifically, the O-ring 17 is fixed to the left end of the inner wall of the outer cylinder 6 for sealing to prevent the leakage of compressed air, ensuring good airtightness during the operation of the assisting rammer. The O-ring 17 can also reduce the friction between the outer cylinder 6 and the internal components. The stepped seal 18 is installed on the left side of the O-ring 17 to provide an additional sealing effect and further prevent gas leakage. The elastic dowel pin two 20 and the elastic dowel pin one 19 are used to buffer and absorb the vibration and impact force during the impact process, thereby protecting the equipment from excessive damage.
[0026] Working principle: Compressed air enters the outer cylinder 6, passes through the male connector 3 and the front connector 2 into the interior of the cylinder body. The air pressure drives the front section 4 and the rear section 5 of the rammer to generate an impact force. The front section 4 of the rammer is connected to the impact sleeve 1, causing the rammer to move within the outer cylinder 6 and strike the anvil. The piston 7 and the piston shock pad 8 reduce the vibration generated by the impact. The air distribution rod 9 helps with gas distribution. The shock pad 10 further reduces the impact of vibration on the equipment.
[0027] By being fixed to the right side of the outer wall of the outer cylinder 6, it provides positioning and support for the equipment during operation. It is installed on the outside of the centering ring 12 to absorb and buffer the impact force during operation and reduce the vibration of the equipment. The limit pin 13 is fixedly connected through the compression spring 14 to prevent excessive movement. The gland packing one 15 and the gland packing two 16 are fixed in the middle and at the top of the outer cylinder 6 to be used for sealing and reducing friction, ensuring the smooth operation of the internal components, ensuring that the assisting rammer can operate stably and efficiently during work, and at the same time reducing the damage to the equipment caused by friction and impact.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
