Description

Technical Field

[0001] This utility model relates to the field of hammer technology, specifically a combined hammer set. Background Technology

[0002] Dynamic compaction refers to the process of dropping a heavy hammer weighing tens to hundreds of tons from a height of several meters to tens of meters to dynamically compact the soil, thereby reducing its compressibility and increasing its strength. Dynamic compaction requires the use of a tamping hammer. It is commonly used in the construction of industrial and civil building foundations to compact the foundation, such as heavy hammer compaction foundations, dynamic compaction foundations, and preloading foundations. Pile foundations also require tamping hammers to drive reinforced concrete precast piles, sheet piles, steel pipe piles, etc., into the strata.

[0003] Currently, some tamping hammers on the market include, for example, a utility model patent with authorization announcement number CN220868171U that discloses a dynamic compaction replacement tamping hammer. This hammer uses a truncated cone-shaped hammer body. When the hammer body sinks into the hammer pit, it can reduce the contact area between the soil and the side wall of the hammer body, thus reducing the soil's adsorption force. The hammer body can be pulled out by connecting it to the lifting mechanism through the hammer connector. This solves the problem of the hammer easily sinking during dynamic compaction replacement construction, which causes the construction period to be occupied and labor to be wasted. However, because this tamping hammer adopts an integrated design, the weight of the hammer body cannot be adjusted according to actual needs, resulting in poor flexibility and inconvenience. Moreover, its large size also occupies a lot of space during transportation, which is quite troublesome.

[0004] Therefore, we propose a combined set of hammers to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of some current tamping hammers, which are designed as an integrated whole and cannot adjust the weight of the hammer body according to actual needs, resulting in poor flexibility and inconvenience. In addition, their large size also occupies a lot of space during transportation, which is quite troublesome.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a combined hammer set, comprising: a hammer set body, the hammer set body including a hammer head and a hammer handle, the hammer handle being fixedly connected to the center position of the upper surface of the hammer head;

[0007] Multiple combined handles are provided on the main body of the hammer sleeve, and the multiple combined handles can be combined with the main body of the hammer sleeve to adjust the length of the combined hammer sleeve.

[0008] Multiple hammer blades are disposed on the main body of the hammer set, and the multiple hammer blades can be combined with the main body of the hammer set to adjust the weight of the combined hammer set;

[0009] The lifting shaft is used to connect to an external lifting mechanism to lift the combined hammer assembly.

[0010] Furthermore, the hammer handle includes a first handle rod, the top end of which is connected to two first connecting plates, each of which has a first connecting hole.

[0011] Furthermore, the combined handle includes a second handle rod, the top end of which is connected to two second connecting plates, each of which has a second connecting hole, and the bottom end of the second handle rod has a connecting slot. The surface of the second handle rod near the bottom end has a connecting insertion hole that passes through the connecting slot. The first connecting plate and the second connecting plate are both adapted to the connecting slot, and the first connecting hole and the second connecting hole correspond to the connecting insertion hole.

[0012] Furthermore, the lifting shaft includes a lifting head, the bottom end of which is connected to a third connecting plate, and the third connecting plate has a third connecting hole.

[0013] Furthermore, the hammer head is provided with a plurality of evenly distributed first vent holes, and the hammer blade is provided with a plurality of evenly distributed second vent holes.

[0014] Furthermore, a lifting groove is provided at the edge of the upper surface of the hammer blade, and a lifting rod is fixed in the lifting groove.

[0015] The beneficial effects of this utility model are as follows: by setting multiple combined handles, the length can be adjusted by combining the main body of the combined handle and the combined handle. The multiple hammer pieces can be adjusted by fitting the hammer pieces onto the hammer handle and the combined handle, which is highly flexible. When transportation is required, the combined hammer can be disassembled into multiple parts for convenient transportation. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0026] Embodiments of this utility model:

[0027] like Figures 1-7 As shown, this utility model provides a combined hammer, including a hammer body 1, multiple combined handles 2, multiple hammer blades 3, and a lifting shaft 4. The hammer body 1 includes a hammer head 101 and a hammer handle 102. The hammer handle 102 is fixedly connected to the center position of the upper surface of the hammer head 101. The lifting shaft 4 includes a lifting head 401. The bottom end of the lifting head 401 is connected to a third connecting plate 402. The third connecting plate 402 has a third connecting hole 4021. The lifting shaft 4 is used to connect with an external lifting mechanism to lift the combined hammer.

[0028] like Figures 1-7 As shown, the hammer handle 102 includes a first handle 1021, and the top end of the first handle 1021 is connected to two first connecting plates 1022. Both first connecting plates 1022 are provided with first connecting holes 10221. When the combined handle body 2 is not installed, the connection between the lifting shaft 4 and the sleeve hammer is achieved through the cooperation of the first connecting holes 10221, the third connecting hole 4021, and the connecting bolt.

[0029] like Figures 1-7As shown, multiple combined handles 2 are mounted on the main body 1 of the hammer. Each combined handle 2 includes a second handle 201. The top end of the second handle 201 is connected to two second connecting plates 202. Each of the two second connecting plates 202 has a second connecting hole 2021. The bottom end of the second handle 201 has a connecting slot 2011. Near the bottom end of the second handle 201, a connecting insertion hole 2012 is formed on the surface of the second handle 201, penetrating the connecting slot 2011. The connecting insertion hole 2012 has an internal thread. Both the first connecting plate 1022 and the second connecting plate 202 are adapted to the connecting slot 2011. The first connecting hole 1022... Both the first connecting plate 1022 and the second connecting hole 2021 correspond to the connecting socket 2012. By inserting the first connecting plate 1022 into the connecting slot 2011, the connection between the combined handle 2 and the hammer is achieved through the cooperation of the first connecting hole 10221, the connecting socket 2012, and the threaded fastener. By inserting the second connecting plate 202 into the connecting slot 2011, the connection between the combined handles 2 is achieved through the cooperation of the second connecting hole 2021, the connecting socket 2012, and the threaded fastener. Multiple combined handles 2 can be combined with the hammer body 1 to adjust the length of the combined hammer.

[0030] like Figures 1-7 As shown, multiple hammer pieces 3 are arranged on the main body 1 of the hammer set. A sleeve hole 303 is opened at the center of the hammer piece 3. The first handle 1021 and the second handle 201 are both adapted to the sleeve hole 303. A lifting groove 302 is opened at the edge of the upper surface of the hammer piece 3. A lifting rod 31 is fixed in the lifting groove 302. With this arrangement, it is convenient to lift the hammer piece 3. Multiple hammer pieces 3 can be combined with the main body 1 of the hammer set to adjust the weight of the combined hammer set. Multiple threaded holes 1012 are opened on the hammer head 101. Multiple matching holes 304 are opened on the hammer piece 3. The connecting bolts can be threaded through the matching holes 304 and threadedly connected to the threaded holes 1012 to limit the hammer piece 3 carried on the main body 1 of the hammer set.

[0031] like Figures 1-7 As shown, the hammer head 101 has multiple evenly distributed first ventilation holes 1011, and the hammer blade 3 has multiple evenly distributed second ventilation holes 301. This arrangement serves two purposes: firstly, it allows for ventilation and exhaust. When the combined hammer is used to compact the foundation, a large amount of gas is generated. If this gas is not discharged in time, it may cause the combined hammer to be sucked into the soil and difficult to lift. Therefore, the first ventilation holes 1011 and the second ventilation holes 301 ensure smooth airflow and prevent the combined hammer from being sucked into the soil during compaction. Secondly, it reduces the loss of compaction force. During compaction, air resistance will cause a certain loss of compaction force. The first ventilation holes 1011 and the second ventilation holes 301 ensure smooth airflow, thereby reducing the loss of compaction force and improving the compaction effect.

[0032] Specifically, the combined handle 2 is lifted using hoisting equipment, allowing the first connecting plate 1022 to be inserted into the connecting slot 2011 and then fixed with threaded fasteners to connect the combined handle 2 to the hammer. Then, as needed, the remaining combined handles 2 are lifted, allowing the second connecting plate 202 of the installed combined handle 2 to be inserted into the connecting slot 2011 and fixed with threaded fasteners to connect the combined handles 2. Then, the hammer 3 is lifted and fitted onto the first handle 1021 or the second handle 201, supported by the hammer head 101. A connecting bolt passes through the adapter hole 304 of the hammer 3 and is threaded into the threaded hole 1012 of the hammer head 101 for limiting and weight adjustment.
