Description

Technical Field

[0001] This utility model relates to the field of feeding technology for rammed piles, and specifically to a feeding structure for rammed pile equipment. Background Technology

[0002] The carrier pile takes the soil at the pile tip as the object, uses a column hammer to impact and form a hole, and compacts and reinforces the surrounding soil. After the pipe is driven to the design elevation, the pile tip is continuously filled and compacted to achieve the corresponding foundation reinforcement purpose. In the current construction and operation, the use of rammed and expanded pile equipment for foundation reinforcement has gradually become a major pipe pile operation method.

[0003] Chinese Patent Application Publication No. CN218880801U discloses a pile ramming and expansion device for carrier piles. This device is equipped with a support frame column, connecting rod, hydraulic cylinder, and hydraulic telescopic rod. When it is necessary to lift the force transmission rod upward, the hydraulic cylinder can be activated. Then, under the connected driving action of the hydraulic telescopic rod and the connecting rod, the force transmission rod can be raised. At the same time, the servo motor is activated, which drives the rotating rod to rotate in the forward direction, so that the traction rope on the surface of the rotating rod can be wound up, which can assist in the upward traction and reduce the pressure when the servo motor is started alone. In addition, during the use of the pile ramming and expansion device, concrete or filler material needs to be put into the pile body. However, when filling the pile with a shovel through the sinking pipe inlet, the opening of the sinking pipe inlet is too small, which can easily cause concrete or filler material to fall on the ground, thus causing material waste.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] This application provides a feeding structure for rammed pile equipment, which solves the problem that when filling material through the sinker pipe inlet using a shovel, the opening of the sinker pipe inlet is too small, causing concrete or filler material to fall onto the ground. This achieves efficient feeding of rammed piles and reduces waste of filler material during the filling process.

[0036] The technical solution in this application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0037] When existing rammed pile equipment uses shovels to fill the material through the feed inlet of the submerged pipe, the diameter of the feed inlet on the pipe is too small due to the limited diameter of the pipe. As a result, concrete or filler material falls onto the ground when the shovel is used to fill the material through the feed inlet, leading to material waste.

[0038] Research has found that, for example Figures 1-5 As shown, by setting the feeding structure into the form of a material bucket, material pipe one, and material pipe two, and utilizing the fact that the inner diameter of the material bucket's feeding end inlet is larger than the diameter of the submerged pipe's feeding inlet, it is easier to add filler into the material bucket through the material bucket's feeding end inlet with a shovel. This solves the problem that when filling with filler through the submerged pipe's feeding inlet with a shovel, the opening of the submerged pipe's feeding inlet is too small, which easily causes concrete or filler to fall onto the ground.

[0039] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figures 1-2 As shown, a feeding structure for a rammed pile equipment is used for feeding the sinking pipe 1 of the rammed pile equipment, including a material bucket 21, a material pipe 22 and a material pipe 23.

[0041] The material pipe 22 is fixedly connected to the material barrel 21 on the side near the material barrel 21 and passes through the material barrel 21. The material pipe 23 is detachably sleeved on the outer surface of the material pipe 22 and passes through the material pipe 22.

[0042] The material trough formed by the material bucket 21, material pipe 1 22 and material pipe 23 is inclined with its lower end facing the sinking pipe 1. The material bucket 21 is inserted into the corresponding inlet 10 on the side of the sinking pipe 1 through material pipe 2 23 for feeding the filler.

[0043] The end of the feed tube 23 is inserted into the feed inlet 10 and is adapted to the port of the feed inlet 10;

[0044] The inner diameter of the feed inlet of the feed hopper 21 is greater than the inner diameter of the discharge outlet of the feed hopper 21, and is also greater than the diameter of the feed inlet 10 of the sink tube 1.

[0045] By setting the feeding structure as a material bucket 21, a material pipe 1 22 and a material pipe 23, and utilizing the fact that the inner diameter of the inlet of the material bucket 21 is larger than the diameter of the inlet 10 of the submerged pipe 1, it is easier to add filler into the material bucket 21 through the inlet of the material bucket 21 with a shovel. This solves the problem that when filling with filler through the inlet 10 of the submerged pipe 1 with a shovel, the opening of the inlet 10 of the submerged pipe 1 is too small, which can easily cause concrete or filler to fall on the ground.

[0046] Meanwhile, the material pipe 23 is designed to be detachable so that different material pipes 23 can be replaced during use. This allows the end of material pipe 23 away from material pipe 22 to be compatible with the diameter of the inlet 10 of the sinking pipe 1, so as to meet the feeding requirements of different inlet 10 diameters of the sinking pipe 1 and facilitate the use of the feeding structure in the filling process of the rammed and expanded pile equipment.

[0047] It should be noted that in actual application, the inner diameter of the feed inlet of the feed hopper 21 is at least 3 times the inner diameter of the feed port 10, and the angle of inclination of the feed trough formed by the feed hopper 21, feed pipe 1 22 and feed pipe 2 23 connected together relative to the ground is greater than 30°.

[0048] like Figures 1-2 as well as Figure 5 As shown, the material bucket 21 is placed on the ground by the support base 2, and the support base 2 is equipped with an abutment block 20 on the side near the sinking pipe 1;

[0049] The second material tube 23 is slidably sleeved on the outer surface of the first material tube 22, and the end face of the second material tube 23 away from the first material tube 22 is an inclined end face 232.

[0050] During feeding, the support seat 2 abuts against the outer wall of the sinking tube 1 through the abutment block 20, and the second material tube 23 abuts against the outer wall of the sinking tube 1 through the abutment plate 24. The inclined end face 232 of the second material tube 23 inside the sinking tube 1 is flush with the inner wall of the sinking tube 1.

[0051] By setting the abutment block 20 and the abutment plate 24, the abutment plate 24 abuts against the sinking tube 1 during feeding, thereby improving the feeding stability. At the same time, the inclined end face 232 of the material tube 23 inside the sinking tube 1 is flush with the inside of the sinking tube 1, thereby reducing the space occupied by the material tube 23 inserted into the sinking tube 1, and making it easier for the filler to enter the sinking tube 1 through the feed inlet 10 to complete the filling.

[0052] like Figures 1-3 As shown, the abutment plate 24 is arc-shaped and fits against the outer wall of the submerged tube 1. The material tube 23 is fitted against the outer wall of the submerged tube 1 through the abutment plate 24, which improves the stability of the material tube 23 when it is inserted into the submerged tube 1, and further facilitates the feeding operation of the filler through the feeding structure.

[0053] Specifically, the abutment plate 24 is welded and fixed to the material tube 23.

[0054] like Figures 1-2 as well as Figure 4 As shown, at least one recess 221 is provided on the outer wall of the first material tube 22, and a protrusion 231 matching the corresponding recess 221 is provided on the inner wall of the second material tube 23.

[0055] The second material tube 23 is slidably connected to the first material tube 22 via a recess 221 and a protrusion 231.

[0056] By setting the recess 221 and the protrusion 231, the material tube 23 is prevented from rotating along the circumference of the material tube 22 after it is fitted onto the material tube 22, thereby improving the stability and convenience of the material tube 23 when sliding relative to the material tube 22 toward the sinker tube 1.

[0057] Specifically, when setting the recess 221 and the protrusion 231, only one recess 221 is set, and a protrusion 231 corresponding to and matching the recess 221 is set, so that the inclined end face 232 of the second material tube 23 is consistent with the inlet 10 and tilted downward, which facilitates the insertion of the second material tube 23 and the sinker tube 1.

[0058] like Figures 1-2 as well as Figures 4-5 As shown, the protrusion 231 on the second feed tube 23 is located on the side of the second feed tube 23 away from the inclined end face 232;

[0059] When the abutting plate 24 abuts against the outer wall of the sinking tube 1, an annular groove 233 is formed between the material tube 22 and the material tube 23 located inside the material tube 23.

[0060] The annular groove 233 formed by feed tube 1 22 and feed tube 23 reduces the contact area between feed tube 23 and the outer surface of feed tube 1 22 when feed tube 23 slides along the outer surface of feed tube 1 22 after feeding is completed, thereby reducing friction and facilitating the sliding of feed tube 23 along the direction of the recess 221.

[0061] During operation, firstly, the material pipe 23, which is compatible with the feed inlet 10 of the sinking pipe 1, is fitted onto the material pipe 22, and the material pipe 23 is manually held down so that it does not detach from the material pipe 22.

[0062] Next, place the support base 2 on the side of the submerged tube 1 where the feed inlet 10 is located, and then push the support base 2 so that the abutment block 20 on the support base 2 contacts and abuts against the outer wall of the submerged tube 1 exposed above the ground.

[0063] Next, manually push the second material tube 23 along the outer surface of the first material tube 22 until the abutting plate 24 on the second material tube 23 abuts against the outer wall of the sinker tube 1. At this time, the second material tube 23 is inserted into the corresponding feed port 10 of the sinker tube 1 for subsequent feeding.

[0064] During feeding, the specific state of the feeding structure is as follows: Figures 1-2 As shown;

[0065] After the feeding structure is installed relative to the sinking pipe 1, the filler is transferred to the material bucket 21 by shovel or other container and fed through material pipe 1 22 and material pipe 2 23. Since the inner diameter of the inlet of the material bucket 21 is large, it can effectively prevent the concrete or filler from falling to the ground when the filler is poured out by shovel, because the opening of the inlet 10 of the sinking pipe 1 is too small.

[0066] The packing slides into the submerged tube 1 through the material trough formed by the material bucket 21, material pipe 1 22 and material pipe 23 on the feeding structure, which are connected together.

[0067] After the filling is completed, the fill material added to the immersed tube 1 is hammered by the column hammer 3 hoisted on the immersed tube 1 to achieve foundation reinforcement.

[0068] In summary, compared with existing technologies, it has the following beneficial effects:

[0069] 1. By setting the feeding structure as a material bucket 21, a material pipe 1 22 and a material pipe 23, the inner diameter of the inlet of the material bucket 21 is larger than the diameter of the inlet 10 of the submerged pipe 1, which makes it easier to add filler into the material bucket 21 through the inlet of the material bucket 21 with a shovel. This solves the problem that when filling with filler through the inlet 10 of the submerged pipe 1 with a shovel, the opening of the inlet 10 of the submerged pipe 1 is too small, which easily causes concrete or filler to fall on the ground.

[0070] 2. At the same time, the material pipe 23 is made detachable so that different material pipes 23 can be replaced during use. The end of the material pipe 23 away from the material pipe 22 can be adapted to the diameter of the inlet 10 of the sinking pipe 1, so as to meet the feeding of different inlet 10 diameters of the sinking pipe 1, and facilitate the use of the feeding structure in the filling process of the rammed and expanded pile equipment.

[0071] 3. By setting the abutting block 20 and the abutting plate 24, the abutting plate 24 abuts against the sinking tube 1 during feeding, thereby improving the feeding stability. At the same time, the inclined end face 232 of the material tube 23 inside the sinking tube 1 is flush with the inside of the sinking tube 1, thereby reducing the space occupied by the material tube 23 inserted into the sinking tube 1, and making it easier for the filler to enter the sinking tube 1 through the feed port 10 to complete the filling material dropping.
