Description

Technical Field

[0001] The invention relates to the technical field of foundation engineering equipment, and in particular to a combined hammer for a pile driver of along-track wedge-shaped bulk material. Background Art

[0002] Bulk material piles are loose materials that do not condense. After reaching a certain bearing capacity, they will spread out in all directions. They are not as self-contained as concrete piles and wooden piles. The single pile bearing capacity of bulk material piles (that is, when a single pile is under load, the strength and stability of the foundation soil and the pile itself can be guaranteed, and the deformation is within the allowable range, so as to ensure the maximum load that the structure can withstand for normal use) is mainly determined by the lateral constraint force of the soil around the pile. If the soil between the piles is loose, weak, and of low strength, and is not reinforced accordingly, the single pile bearing capacity will be very small, and the waste of resources will be very large. We now use a construction method for wedge-shaped composite bulk material piles to first shape the earth-rock retaining wall, and then form a wedge-shaped composite bulk material pile body through the lower pile body, the middle pile body, the wedge-shaped upper pile body, and the top expanded pile body. The construction is layered, and different pile bodies have different construction requirements. The construction equipment in the prior art cannot meet the construction requirements of the wedge-shaped composite bulk material pile body.

[0003] At the same time, the following situations may occur during the construction process: During the piling process, the hammer body crushes the rocks in the soil and squeezes the crushed rocks to the side of the pile through the impact force to form a soil and stone retaining wall. However, if there are inclined rocks in a special position and multiple impacts still cannot break them, the hammer body will be guided to deviate. The hanging ears on the top of the hammer body are connected to the guide rails and are relatively fixed, which will cause the hammer body and the handle to separate, or the track device (including the track) will be pulled or pushed to deform and damage, and additional working hours will be required to re-hang the hammer and repair the links, affecting efficiency. Secondly, if the hammer body is tilted and the hammer body has entered the soil, the upward pull force of the hammer body will be greatly weakened under the clamping effect of the gravel and soil, and it may also cause damage to the equipment, thereby increasing the maintenance cost again and delaying the construction period.

[0004] In view of this, we propose a combination hammer for a pile driver of along-track wedge-shaped bulk materials. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a combined hammer for a pile driver of along-track wedge-shaped bulk materials.

[0006] In order to solve the above technical problems, the technical solution of the present invention is:

[0007] A combined hammer for a pile driver of wedge-shaped bulk materials along the track, characterized in that it is composed of a gooseneck hammer along the track, a flat cone long-neck middle hammer, and a flat cone flat hammer.

[0008] The top of the gooseneck hammer is provided with a hanging head, and the hanging head is connected to the small hammer tube and the large hammer tube of the gooseneck hammer through the gooseneck connecting section by a universal micro-expansion connection mechanism, and a stone breaking mechanism is installed at the bottom of the gooseneck hammer.

[0009] A hanging head is provided on the top of the flat-cone long-necked middle hammer, and the hanging head is connected to the hammer body of the flat-cone middle hammer through a long-necked hammer handle;

[0010] The flat cone flat hammer is in an oblate shape as a whole, and is used to achieve compaction of the upper wedge-shaped pile body, shaping of the top wedge-shaped expanded-diameter pile body, and forming of the pile body in which the pile body and the retaining wall are integrated into one.

[0011] Preferably, a large hammer tube is provided at the bottom of the small hammer tube, and the bottom of the large hammer tube is connected to the main rod section to obtain a rigid-flexible conversion effect of the hammer body.

[0012] Preferably, the bottom of the main rod section is connected to one or more adjustment sections to adjust the hammer weight and the height of the hammer body and facilitate connection with different types of hammer heads. The bottom of the adjustment section is connected to a connecting hammer head section, and the connecting hammer head section is used to connect a stone breaking mechanism.

[0013] Preferably, the flat cone-shaped flat hammer is provided with a hanging head at the top, and anti-blocking vents are provided in the middle and at the bottom.

[0014] Preferably, the number of the gooseneck connecting sections is one or more.

[0015] Preferably, the stone breaking mechanism comprises a base.

[0016] Preferably, one or more conical hammer heads are installed on the base.

[0017] Preferably, a conical handle is provided on the top of the base, which is clamped with a transverse pin in the bottom groove of the gooseneck hammer along the track and is further fixed by means of bayonet pins on both sides, and a conical sleeve is provided on the periphery of the conical handle.

[0018] Preferably, the universal micro-expansion connection mechanism includes an upper seat, a lower seat, and a main rod. One end of the main rod is connected to the lower seat via a connecting shaft using a clamping plate, and the other end of the main rod is connected to the upper seat via a main pin and a auxiliary pin. The upper seat is further fixed to the periphery of the main rod via a rib plate.

[0019] Preferably, the upper seat is fixedly connected to the hanging head or the gooseneck connecting section, and the lower seat is fixedly connected to the gooseneck connecting section or the small hammer tube.

[0020] Beneficial effects:

[0021] 1. The gooseneck hammer along the track tamps the soil from top to bottom. The downward impact of the gooseneck hammer along the track breaks the stones. The broken stones squeeze the soil laterally. The lateral soil and crushed stones are mixed more and more densely due to the squeezing, thereby forming a complete and solid retaining wall of the pile hole. The flat-cone long-necked middle hammer continuously tamps the replacement material in the pile hole, so that the replacement material becomes one under the surrounding constraint of the soil and stone retaining wall. Finally, the flat-cone flat hammer continues to tamp and compact to form a top wedge-shaped expanded-diameter pile body, so that the soil and stone retaining wall, the lower pile body, the middle pile body, the upper wedge-shaped pile body, and the top expanded-diameter pile body become one, which is stable and reliable.

[0022] 2. Through the universal micro-hole expansion connection mechanism at both ends of the gooseneck connection section and the connection with the small and medium hammer tubes of the hanging head and the gooseneck hammer along the track, the flexible connection between the hammer body and the pile driver (track) is achieved through the "universal micro-hole expansion connection mechanism", so that during the drilling operation, especially when the bottom of the hammer touches a large-diameter block stone or hard object, the upper end of the along-track hammer will naturally produce a certain degree of micro-swing (front and back or left and right). By making good use of this micro-swing, it can not only eliminate the adverse factors caused by the rigid connection between the original pile driver track and the along-track hammer (causing hard collision with the pile driver track and corresponding distortion and damage), but also achieve a certain degree of micro-hole expansion effect of gradually increasing from bottom to top for the pile hole;

[0023] 3. By setting a stone breaking mechanism at the bottom of the gooseneck hammer along the track, different forms of conical hammer heads can be installed according to actual needs to meet the construction requirements of different sites. In the case of large rocks on inclined surfaces or sideways that are difficult to be broken by one conical hammer head, one conical head can be used to break the rocks first, and the others can follow up to deal with the impact of the skewed hammer caused by large rocks on the inclined surface. This can not only solve the problem of large rocks on the inclined surface that are difficult to break, but also greatly reduce the frequency of machine failure and improve construction efficiency.

[0024] 4. The bottom stone breaking mechanism is connected with the horizontal pin at the bottom of the gooseneck hammer along the track through the cone handle at the top of the base to facilitate quick disassembly, which greatly improves the construction efficiency.

DETAILED DESCRIPTION

[0037] The specific embodiments of the present invention are further described below. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Give a brief but clear description of the core technical problems to be solved by this application, the technical solutions to be used to solve the core technical problems, and the technical effects that can be achieved.

[0039] like Figure 1-11 As shown, the present invention provides a combined hammer for a pile driver of along-track wedge-shaped bulk materials, which is composed of an along-track gooseneck hammer 1, a flat-cone long-neck middle hammer 2, and a flat-cone flat hammer 3.

[0040] A hanging head 4 is provided on the top of the gooseneck hammer 1 , and the hanging head 4 connects the small hammer tube 103 and the large hammer tube 102 of the gooseneck hammer 1 through the gooseneck connecting section 104 and the universal micro-expansion connection mechanism 105 .

[0041] It is worth further explaining that the hanging head 5 is used to be laterally connected to the pile driver track.

[0042] In this embodiment, a large hammer tube 102 is provided at the bottom of the small hammer tube 103 .

[0043] In this embodiment, the bottom of the large hammer tube 102 is connected to the main rod section 101 .

[0044] In this embodiment, the bottom of the main rod section 101 is connected to one or more adjustment sections 106 to adjust the hammer weight and the height of the hammer body and facilitate connection with hammer heads of different models. The bottom of the adjustment section 106 is connected to the connecting hammer head section 107, and the connecting hammer head section 107 is used to connect the stone breaking mechanism 5.

[0045] It is worth further explaining that the small hammer tube 103, the large hammer tube 102, the main rod section 101, and the adjustment section 106 are all connected by welding, and are further fixed by reinforcing ribs on the side.

[0046] It is worth further explaining that, according to construction needs, the adjusting section 106 can be added to increase the length of the along-track gooseneck hammer 1 , and vice versa, to reduce the length of the along-track gooseneck hammer 1 .

[0047] In this embodiment, the universal micro-expansion connection mechanism 105 includes an upper seat 1051, a lower seat 1052, and a main rod 1053. One end of the main rod 1053 is connected to the lower seat 1052 via a connecting shaft 1054 using a clamping plate 1055, and the other end of the main rod 1053 is connected to the upper seat 1051 via a main pin 1056 and a auxiliary pin 1057. The outer periphery of the main rod 1053 is further fixed to the upper seat 1051 via a rib plate 1058.

[0048] It is worth further explaining that the overlapping portion between the lower end of the main rod 1053 and the lower seat 1052 is penetrated by the connecting shaft 1054, and then the clamping plate 1055 and bolts are used to fix the two sections of the connecting shaft 1054 to the main rod 1053 and the lower seat 1052 respectively, so that the lower seat 1052 can swing and realize the universal joint function.

[0049] In this embodiment, the upper seat 1051 is fixedly connected to the hanging head 4 or the gooseneck connecting section 104 , and the lower seat 1052 is fixedly connected to the gooseneck connecting section 104 or the small hammer tube 103 .

[0050] In this embodiment, there are one or more gooseneck connecting sections 104 .

[0051] like Figure 3 As shown:

[0052] A hanging head 4 is provided on the top of the flat-cone long-neck middle hammer 2, and the hanging head 4 is connected to the flat-cone middle hammer body 202 through a long-neck hammer handle 201.

[0053] It is worth further explaining that the flat-cone long-necked middle hammer 2 is used to achieve the purpose of continuing to backfill the replacement material in the pile hole after the lower and middle pile bodies are formed, and then replacing the flat-cone long-necked middle hammer 2 for continuous tamping, thereby synchronously completing the further tamping, compaction and expansion of the middle and lower wedge-shaped pile bodies through the conduction of the tamping force, and at the same time forming the outer mold of the wedge-shaped pile body with a larger upper part and a smaller lower part.

[0054] like Figure 4 As shown:

[0055] A hanging head 4 is provided on the top of the flat cone-shaped flat hammer 3.

[0056] The flat cone flat hammer 3 is in an oblate shape as a whole, and is used to achieve compaction of the upper wedge-shaped pile body, shaping of the top wedge-shaped expanded-diameter pile body, and forming of the pile body in which the pile body and the retaining wall are integrated into one.

[0057] It is worth further explaining that the flat-cone flat hammer 3 continuously tamps the outer mold of the wedge-shaped pile body backfilled with replacement material and the replacement material inside the mold, and stops tamping after reaching the hammer stop standard, forming a wedge-shaped pile body with replacement material on the upper part that gradually expands from bottom to top, and at the same time forming an expanded diameter outer mold (tamping pit) at the top of the pile body, as well as filling the replacement material in the outer mold at the top of the pile body, and continuing to tamp it densely with a flat-cone flat hammer to form a top wedge-shaped expanded diameter pile body.

[0058] It is worth further explaining that anti-blocking vent holes are provided in the middle and at the bottom of the flat cone-shaped flat hammer 3 .

[0059] like Figure 2 , 5 As shown:

[0060] A stone breaking mechanism 5 is installed at the bottom of the gooseneck hammer 1 along the track.

[0061] In this embodiment, the stone breaking mechanism 5 includes a base 501 .

[0062] In this embodiment, one or more conical hammer heads 502 are installed on the base 501 .

[0063] It is worth further explaining that, when performing a single extrusion and impact operation, a conical hammer head 502 is installed on the base 501 using bolts, so that the stone can be quickly broken and crushed during the construction process, thereby accelerating the drilling operation.

[0064] It is worth further explaining that, in the case where it is difficult to crush stones with a single conical hammer, multiple conical hammers 502 can be installed on the base 501 by bolts or welding, so that one conical hammer touches the bottom to break the stone first, and the others follow up, in order to cope with the effect of the deflected hammer caused by large stones on the inclined surface. This can not only solve the problem of large stones on the inclined surface that are difficult to crush, but also greatly reduce the frequency of machine failures such as the deflected hammer colliding with the track-following device, thereby improving construction efficiency.

[0065] It is worth further explaining that, when construction requires, the stone breaking mechanism 5 can be removed and converted into a pile compacting mechanism.

[0066] like Figure 6 As shown:

[0067] When the stone breaking and squeezing are completed and the pile hole meets the design requirements, the hammer head is quickly disassembled to form a "flat-headed" tamping hammer head (hammer body): In order to achieve the purpose of quick disassembly, the connection method between the hammer head and the hammer body adopts a "pin-type connection device" to improve the construction efficiency.

[0068] like Figure 7 , Fig.10 As shown:

[0069] It is worth further explaining that a flexible connection is achieved through the "universal joint" to form a "gooseneck" function; during the driving process, especially when the bottom of the hammer touches a large-diameter stone or hard object, the upper end of the along-track gooseneck hammer 1 will naturally produce a certain degree of micro-swing (front and back or left and right), and the "universal joint" effect can leave a certain amount of room for movement for this swing, forming a gooseneck function and achieving a flexible connection effect, which can not only eliminate the adverse factors caused by the rigid connection between the original pile driver track and the along-track hammer (causing a hard collision with the pile driver track and corresponding distortion and damage), but also achieve a certain degree of micro-expansion effect on the pile hole that gradually increases from bottom to top.

[0070] like Figure 8 As shown:

[0071] In this embodiment, a conical handle 503 is provided on the top of the base 501 and is clamped with a transverse pin 504 in the bottom groove of the track-following gooseneck hammer 1 and further fixed by means of a clamping pin 505 on both sides. A conical sleeve 506 is provided on the periphery of the conical handle 503 .

[0072] It is worth further explaining that a groove is provided at the bottom of the gooseneck hammer 1, and a horizontal pin 504 is arranged across the groove. The conical handle 503 fixedly connected to the top of the base 501 can just be inserted into the center of the horizontal pin 504. The horizontal pin 504 and the conical handle 503 are clamped together, and then further fixed by the clamping pins 505 on both sides of the horizontal pin 504, thereby realizing the connection between the stone breaking mechanism 5 and the gooseneck hammer 1. The conical handle 503 can be removed from the horizontal pin 504 to complete the disassembly of the stone breaking mechanism 5, and the corresponding cone head can be replaced at any time according to different geological needs.

[0073] The mechanism achieves rapid disassembly and can be changed according to different construction needs, greatly improving construction efficiency.

[0074] like Fig. 9 As shown:

[0075] In this embodiment, the construction of the wedge-shaped composite bulk material pile is completed by sequentially using the track gooseneck hammer 1, the flat cone long neck middle hammer 2, and the flat cone flat hammer 3. The wedge-shaped pile hole of the earth and stone retaining wall is shaped first, and then the wedge-shaped composite bulk material pile body is formed through the lower pile body, the middle pile body, the wedge-shaped upper pile body, and the top expanded pile body. The construction is carried out layer by layer, and different pile bodies have different construction requirements to meet the construction requirements of the wedge-shaped composite bulk material pile body.

[0076] The gooseneck hammer 1 along the track tamps the soil from top to bottom. The downward impact of the gooseneck hammer 1 crushes the stones. The crushed stones squeeze the soil laterally. The lateral soil and crushed stones are mixed more and more densely due to the squeezing, thereby forming a complete and solid protective wall of the pile hole. The flat-cone long-necked middle hammer 2 continuously tamps the replacement material in the pile hole, so that the replacement material becomes one under the surrounding constraint of the soil and stone protective wall. Finally, the flat-cone flat hammer 3 continues to tamp and compact to form a top wedge-shaped expanded-diameter pile body, so that the soil and stone protective wall, the lower pile body, the middle pile body, the upper wedge-shaped pile body, and the top expanded-diameter pile body become one, which is stable and reliable.

[0077] like Fig.11 As shown, during the construction process:

[0078] S1, stop the construction equipment at the construction area, align the gooseneck hammer 1 of the pile driver with the pile position to prepare for the pile driving operation;

[0079] S2, micro-hole expansion: the gooseneck hammer 1 along the track tamps the soil from top to bottom, and the downward impact of the gooseneck hammer 1 crushes the stones. The crushed stones squeeze the soil laterally, and the soil and crushed stones on the side are mixed more and more densely due to the squeezing, thereby forming a complete and solid protective wall of the pile hole. At the same time, due to the lateral connection between the top of the gooseneck hammer 1 along the track and the pile driver track, a flexible connection is achieved through the universal micro-hole expansion connection mechanism 105, forming a "gooseneck" function; so that during the injection process, especially when the bottom of the hammer touches a large-diameter stone or hard object, the upper end of the gooseneck hammer 1 along the track will naturally produce a certain degree of micro-swing (front and back or left and right), and the "universal joint" effect can leave a certain amount of activity space for this swing, forming a flexible connection effect, so that it can not only eliminate the adverse factors caused by the rigid connection between the original pile driver track and the gooseneck hammer along the track (causing hard collision with the pile driver track and corresponding distortion and damage), but also can achieve a certain degree of micro-hole expansion effect from bottom to top on the pile hole, forming a complete and continuous wedge-shaped pile hole;

[0080] S3, lower pile formation: after the pile hole and stable retaining wall are formed, the replacement material is filled in sections from bottom to top, and the hammer head is replaced for section-by-section tamping to ensure that each section of the lower pile body reaches the vertical compaction of the pile body and the lateral extrusion of the hole wall, so that the pile body and the retaining wall form a tightly combined vertical bearing body; at the same time, a wedge-shaped replacement material lower pile body with a diameter gradually increasing from bottom to top is formed;

[0081] S4, middle pile formation: fill the pile hole with replacement material in sections from bottom to top, and tamp it in sections at the same time, to ensure that each section of the middle pile body reaches the vertical compaction of the pile body and the lateral extrusion of the hole wall, so that the pile body and the retaining wall form a tightly combined vertical bearing body; at the same time, a wedge-shaped replacement material middle pile body with a diameter gradually increasing from bottom to top is formed;

[0082] S5, upper pile body mold: after the lower and middle pile bodies are formed, the replacement material is continued to be backfilled in the pile hole, and then the flat cone long neck middle hammer 2 is replaced to continuously tamp, and the middle and lower wedge-shaped pile bodies are further tamped, compacted and expanded synchronously through the tamping force transmission, and at the same time, the upper wedge-shaped pile body outer mold with a larger upper part and a smaller lower part is formed;

[0083] S6, forming the upper pile body: the inner cavity of the outer mold of the wedge-shaped pile body formed by the operation in S5 is filled with replacement material; the outer mold of the wedge-shaped pile body backfilled with replacement material in S5 and the replacement material in the mold are continuously rammed by a flat cone flat hammer 3, and the ramming is stopped after the hammer withdrawal standard is reached, forming a wedge-shaped pile body of the upper part of the replacement material that gradually expands from bottom to top, and at the same time forming an expanded outer mold (ramming pit) at the top of the pile body;

[0084] S7, forming the pile top: filling the outer mold at the top of the pile body with replacement material, and continuing to compact it with a flat cone hammer 3 to form a wedge-shaped expanded diameter pile body at the top;

[0085] S8. The wedge-shaped composite bulk material pile is constructed through the above steps to form a complete and continuous wedge-shaped composite bulk material pile body, which is composed of multiple sections of pile bodies with different diameters and shapes stacked on the same vertical line, and the pile body with a diameter gradually increasing from bottom to top is tightly integrated with the retaining wall.

[0086] The embodiments of the present invention are described in detail above, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the protection scope of the present invention.
