Description

Technical Field

[0001] This application relates to the field of hand tools, and in particular to a multi-functional hammer for installing and removing aluminum alloy formwork. Background Technology

[0002] Aluminum alloy formwork is a type of metal mold with strong load-bearing capacity, lightweight structure, flexible assembly and disassembly, and recyclability. Its recycling is convenient. Through the large-scale use of aluminum alloy formwork, the amount of wood used in the construction pouring process can be greatly reduced. Long-term use of aluminum alloy formwork can effectively reduce the construction cost of building pouring. Therefore, it is being gradually promoted in the current construction industry.

[0003] Aluminum alloy formwork requires connection via pins or bolts during use. After concrete is poured between the aluminum alloy formwork panels to form a wall, the formwork is then dismantled. During the installation and dismantling of the aluminum alloy formwork, workers need to perform operations such as hammering, drilling, and prying. These operations require the use of multiple tools, which means that workers need to carry a large number of specialized tools, such as hammers, electric drills, and crowbars. Carrying too many tools can easily lead to inconvenience for workers, making their operations less flexible and thus affecting construction efficiency.

[0004] To address these issues, a multi-functional hammer for installing and removing aluminum alloy templates is proposed. Summary of the Invention

[0005] The purpose of this application is to provide a multi-functional hammer to adapt to the multiple operational needs in the installation process of aluminum alloy formwork, thereby improving the convenience of aluminum alloy formwork assembly and disassembly and thus improving construction efficiency. Compared with the prior art, this application provides a multi-functional hammer for the installation and disassembly of aluminum alloy formwork, including a cylindrical outer shell, a motor fixedly installed inside the outer shell, a control panel fixedly installed on the outer wall of the outer shell, an outer shell two fixedly connected to the upper end of the outer shell, and a hammer sleeve slidably installed inside the outer shell two and parallel to it. An aluminum hammer body extending to its two outer ends is installed inside the hammer sleeve. A base is fixedly installed on the lower outer wall of the hammer sleeve, and a transverse groove is opened in the middle of the base. An eccentric wheel is driven and connected to the drive shaft above the motor, and a swing rod extending into the transverse groove is fixedly installed on the outer wall of the eccentric wheel. A clamping platform is rotatably installed at the lower end of the outer shell, which is driven and connected to the drive shaft below the motor, and a drill bit is clamped on the clamping platform.

[0006] By installing the motor inside the outer casing, the high-frequency reciprocating movement of the aluminum hammer body inside the upper hammer sleeve, driven by the motor, allows for the hammering of aluminum alloy templates without requiring large swings of the device. This reduces the labor intensity for operators. Furthermore, the motor drives the drill bit held on the lower clamping platform to rotate, enabling drilling operations. This effectively increases the device's usage modes, enhancing its functionality and improving its flexibility and convenience during operation.

[0007] Optionally, a bearing is fitted onto the outer side of the swing arm, and the outer dimensions of the bearing are adapted to the inner dimensions of the transverse groove.

[0008] Optionally, a limiting shell is fixedly connected between the first outer shell and the second outer shell, and the internal dimensions of the limiting shell are adapted to the movement trajectory of the platform.

[0009] Optionally, the aluminum hammer body is designed as a cylindrical structure. The aluminum hammer body is slidably installed inside the hammer sleeve. Both ends of the hammer sleeve are fixedly installed with a gathering ring sleeved on the outside of the aluminum hammer body. The end wall of the gathering ring is evenly provided with a circumferentially distributed through groove. The outer diameter of the gathering ring gradually increases on the side away from the hammer sleeve. A threaded ring is threaded onto the outer side of the gathering ring.

[0010] Optionally, a connecting ring is fixedly installed at the lower end of the outer casing, which is sleeved on the outside of the clamping table, and a handle that is movably sleeved on the outside of the clamping table is connected to the internal thread of the connecting ring.

[0011] Optionally, a connecting ring is also fixedly installed on the upper outer wall of the second outer casing. A bearing rod is rotatably installed inside the lower end of the handle, and the bearing rod, after rotation, forms a T-shaped structure with the handle. A threaded sleeve is threaded onto the outer side of the handle, and the threaded sleeve is fitted on the outer side of the bearing rod. The outer dimensions of the bearing rod are compatible with the inner dimensions of the threaded sleeve.

[0012] Optionally, pry bars of different sizes are fixed at the upper and lower ends of the support rod, and a protective cover is fitted on the outside of each pry bar, with the protective cover interference fit at the upper and lower ends of the support rod.

[0013] Optionally, the handle near the connecting ring has a hollow structure, and a storage column is slidably installed inside the hollow structure. Multiple vertically arranged storage slots are distributed around the outer end wall of the storage column, and the drill bit is stored in the storage slot.

[0014] Optionally, a grinding rod is also stored in the storage slot, which is filled with a sponge pad that wraps around the drill bit and the grinding rod. The storage column has a through hole located directly below the rotating shaft of the clamping table, and a spring that provides elastic support to the bottom of the storage column is installed in the hollow structure.

[0015] Optionally, a clutch is installed between the drive shaft and the eccentric wheel on the upper part of the housing, and a clutch is also installed between the drive shaft and the clamping table on the lower part of the housing. Only one of the two clutches is in operation at any given time, and a pressure sensor is installed in both connecting rings.

[0016] Compared to existing technologies, the advantages of this application are:

[0017] (1) This application installs a motor inside the outer casing. By starting the motor, the aluminum hammer body inside the upper hammer sleeve moves back and forth at high frequency. This allows the aluminum alloy template to be struck without swinging the device too much, which helps reduce the labor intensity of the workers. The motor also drives the drill bit held on the lower clamping table to rotate, which can be used for drilling. This effectively increases the usage modes of the device and improves its functionality. It also improves the flexibility and convenience of the operation. At the same time, the use of a soft aluminum hammer body to strike the aluminum alloy template provides effective striking force while avoiding damage to the surface of the aluminum alloy template, which helps improve the safety of the aluminum alloy template during disassembly and assembly.

[0018] (2) By firmly installing a bearing that matches the internal dimensions of the transverse groove on the swing rod, the connection stability between the swing rod and the transverse groove can be effectively improved, avoiding severe wear caused by direct connection between the swing rod and the transverse groove. The use of replaceable bearings for supplementary connection can effectively improve the convenience of later maintenance of the device.

[0019] (3) By installing the limiting shell between the outer shell 1 and the outer shell 2, the platform is restricted by the limiting shell, so that the platform can only move left and right, avoiding the platform from deflecting when it is moved by the swing rod, which effectively improves the stability of the drive hammer sleeve to move left and right at high frequency during the use of the device.

[0020] (4) The installation of the aluminum hammer body is achieved by the cooperation of the tightening ring and the screw ring, which can effectively improve the convenience of subsequent replacement of the aluminum hammer body. At the same time, by extending the left and right ends of the aluminum hammer body to the outer side of the tightening ring in the corresponding direction, the movement direction of the aluminum hammer body can be changed by alternating the striking direction operation mode. With the tightening ring, the position of the curling deformation at the end of the aluminum hammer body can be corrected, which is conducive to extending the service life of the aluminum hammer body.

[0021] (5) By installing the handle on the bottom of the outer casing, the lever arm of the device during the striking operation can be effectively extended, which is conducive to improving the convenience of using the device. At the same time, by using the connecting ring and the threaded connection of the handle to install the handle, it is conducive to ensuring the ease of disassembly and assembly of the handle.

[0022] (6) By installing another connecting ring on the upper outer wall of the outer casing II, the position of the handle can be flexibly changed, providing a stable gripping position when the device is drilling. The presence of the bearing rod can form a T-shaped structure with the handle after rotation, which is convenient to grip and improves the ease of operation of the device. At the same time, the state of the bearing rod can be fixed by rotating the screw sleeve, which helps to ensure the structural stability after the bearing rod is rotated and adjusted.

[0023] (7) By installing two pry bars of different sizes at the upper and lower ends of the support rod respectively, the pry bar can be used to pry during the disassembly and assembly of the aluminum alloy template, thereby further improving the functionality of the device in actual use.

[0024] (8) By placing the storage column in the hollow structure inside the handle and opening multiple storage slots on the outer end wall of the storage column, it can be used to store drill bits of different specifications, which helps to ensure the convenience of drill bit replacement.

[0025] (9) By placing the grinding rod in the storage slot, the grinding rod can be replaced and installed on the clamping table, so that the device has a grinding function, which further improves the functionality of the device in actual use. By opening the hole through the inside of the storage column, the handle can be reinstalled without disassembly after the drill bit or grinding rod is installed on the clamping table, which helps to improve the convenience of the device in use.

[0026] (10) By installing clutches between the drive shaft and the eccentric wheel on the upper part of the housing and between the drive shaft and the clamping table on the lower part of the housing, and in conjunction with the pressure sensors in the upper and lower connecting rings, the transmission of the upper and lower clutches can be controlled according to the actual use status of the device, which is conducive to ensuring the safety of the device in actual use.

[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] Example 1

[0041] This application discloses a multi-functional hammer for installing and removing aluminum alloy formwork. Please refer to [link / reference]. Figure 1 - Figure 10The device includes a cylindrical outer shell 1, a motor 101 fixedly installed inside the outer shell 1, a control panel 102 fixedly installed on the outer wall of the outer shell 1, an outer shell 2 perpendicularly connected to the upper end of the outer shell 1, a hammer sleeve 201 parallel to the outer shell 2 being slidably installed inside the outer shell 2, an aluminum hammer body 204 extending to the outer sides of both ends of the hammer sleeve 201 being installed inside the hammer sleeve 201, a base 205 fixedly installed on the lower outer wall of the hammer sleeve 201, and a transverse groove 206 being provided in the middle of the base 205, an eccentric wheel 207 being driven and connected to the drive shaft above the motor 101, and a swing rod 208 extending into the transverse groove 206 being fixedly installed on the outer wall of the eccentric wheel 207, and a clamping table 3 rotatably installed at the lower end of the outer shell 1 and driven and connected to the drive shaft below the motor 101, and a drill bit 301 being clamped and held on the clamping table 3.

[0042] Workers connect the device to an external power source via wires, allowing the external power supply to provide power. They can then use the device flexibly. When installing and dismantling aluminum alloy formwork, workers can swing the device to strike the formwork using the aluminum hammer body 204. Because the aluminum hammer body 204 is made of aluminum, its hardness is less than that of the aluminum alloy formwork, effectively preventing dents from forming on the surface of the formwork. This helps ensure stability and safety during the installation and dismantling process. While swinging the device to strike, workers can control the motor via the control panel 102. When 101 is activated, the drive shaft above it drives the eccentric wheel 207 to rotate, causing the swing arm 208 to rotate around the rotation center of the eccentric wheel 207. During this process, the swing arm 208 moves within the transverse groove 206, causing the platform 205 to move back and forth left and right, thereby driving the aluminum hammer body 204 inside the hammer sleeve 201 to move cyclically in the left and right directions at high frequency. In this mode, the operator does not need to swing the entire multi-functional hammer, but only needs to place the aluminum hammer body 204 against the aluminum alloy template to be struck. By moving the aluminum hammer body 204 back and forth at high frequency, the striking operation of the aluminum alloy template can be achieved, which helps to reduce the labor intensity of the operator.

[0043] During use, the operator can control the motor 101 to rotate the clamping platform 3, causing the drill bit 301 clamped on the clamping platform 3 to rotate at high speed and drill at the target location. By installing the motor 101 inside the outer casing 1, the motor 101 drives the aluminum hammer body 204 in the upper hammer sleeve 201 to move back and forth at high frequency. This allows for striking the aluminum alloy template without having to swing the device significantly, reducing the labor intensity of the operator. The motor 101 also drives the drill bit 301 clamped on the lower clamping platform 3 to rotate, enabling drilling. This effectively increases the device's usage modes, enhances its functionality, and improves the flexibility and convenience of its operation. Installing the aluminum hammer body 204 inside the hammer sleeve 201 provides effective striking force while preventing damage to the surface of the aluminum alloy template, thus improving the safety of the aluminum alloy template during assembly and disassembly.

[0044] Please see Figure 4 and Figure 7 A bearing 209 is sleeved on the outer side of the swing rod 208, and the outer dimensions of the bearing 209 are adapted to the inner dimensions of the transverse groove 206. During the use of this device, by firmly installing the bearing 209, which is adapted to the inner dimensions of the transverse groove 206, on the swing rod 208, the connection stability between the swing rod 208 and the transverse groove 206 can be effectively improved, and the direct connection between the swing rod 208 and the transverse groove 206 can be avoided, which would lead to severe wear. The use of replaceable bearings 209 for supplementary connection can effectively improve the convenience of later maintenance of this device.

[0045] Please see Figure 1 and Figure 3 A limiting shell 4 is fixedly connected between the outer shell 1 and the outer shell 2 and is movably sleeved on the outside of the platform 205. The internal dimensions of the limiting shell 4 are adapted to the movement trajectory of the platform 205. During the use of the device, by installing the limiting shell 4 between the outer shell 1 and the outer shell 2, the platform 205 is restricted by the limiting shell 4, so that the platform 205 can only move left and right. This prevents the platform 205 from deflecting when it is turned by the swing rod 208, and effectively improves the stability of the drive hammer sleeve 201 to move left and right at high frequency during the use of the device.

[0046] Example 2

[0047] This application discloses a multi-functional hammer for installing and removing aluminum alloy formwork. Please refer to [link / reference]. Figure 1 - Figure 10The aluminum hammer body 204 is cylindrical in shape and is slidably installed inside the hammer sleeve 201. Both ends of the hammer sleeve 201 are fixedly installed with a gathering ring 202 sleeved on the outside of the aluminum hammer body 204. The end wall of the gathering ring 202 is evenly provided with a through groove distributed around it. The outer diameter of the gathering ring 202 gradually increases on the side away from the hammer sleeve 201. A threaded ring 203 is threaded onto the outer side of the gathering ring 202.

[0048] During use, when the rotating screw ring 203 moves away from the hammer sleeve 201, it can tighten the end of the retaining ring 202, thereby locking and fixing the internal aluminum hammer body 204. When using this device to strike the aluminum alloy template, since the hardness of the aluminum hammer body 204 is less than that of the aluminum alloy template, the edge of the striking surface of the aluminum hammer body 204 is easily deformed outward under pressure. Similarly, during the striking process, since the aluminum hammer body 204 is tightly installed by the retaining ring 202 and the screw ring 203, the aluminum hammer body 204 can move slowly in the opposite direction of the striking direction. The outwardly deformed end of the aluminum hammer body 204 is squeezed and corrected when it is retracted into the retaining ring 202. This allows the device to complete the striking operation by using the left and right ends of the aluminum hammer body 204 alternately, while reducing the impact of the deformation of the end of the aluminum hammer body 204 on the striking operation.

[0049] This application achieves the installation of the aluminum hammer body 204 through the cooperation of the retaining ring 202 and the screw ring 203, which can effectively improve the convenience of subsequent replacement of the aluminum hammer body 204. At the same time, by extending the left and right ends of the aluminum hammer body 204 to the outer side of the retaining ring 202 in the corresponding direction, the movement direction of the aluminum hammer body 204 can be changed by alternating the striking direction operation mode. With the help of the retaining ring 202 to tighten the aluminum hammer body 204, the curling deformation position of the end of the aluminum hammer body 204 can be corrected, which is conducive to extending the service life of the aluminum hammer body 204.

[0050] Example 3

[0051] This application discloses a multi-functional hammer for installing and removing aluminum alloy formwork. Please refer to [link / reference]. Figure 1 - Figure 10 A connecting ring 5 is fixedly installed on the lower end of the outer shell 1, which is sleeved on the outside of the clamping platform 3. The inner thread of the connecting ring 5 is connected to a handle 501 that is movably sleeved on the outside of the clamping platform 3. During the use of this device, by installing the handle 501 under the outer shell 1, the force arm of the device during the striking operation can be effectively extended, which is conducive to improving the convenience of using the device. At the same time, by using the threaded connection between the connecting ring 5 and the handle 501 to realize the installation connection of the handle 501, it is conducive to ensuring the ease of installation and removal of the handle 501.

[0052] Please see Figure 5 A connecting ring 5 is also fixedly installed on the upper outer wall of the outer casing 2. A bearing rod 502 is rotatably installed inside the lower end of the handle 501, and the bearing rod 502 forms a T-shaped structure with the handle 501 after rotation. A threaded sleeve 503 is threaded onto the outer side of the handle 501, and the threaded sleeve 503 is fitted on the outer side of the bearing rod 502. The outer dimensions of the bearing rod 502 are compatible with the inner dimensions of the threaded sleeve 503. During the use of this device, by installing another connecting ring 5 on the upper outer wall of the outer casing 2, the position of the handle 501 can be flexibly changed, providing a stable grip position when the device is drilling. The presence of the bearing rod 502 can form a T-shaped structure with the handle 501 after rotation, which is convenient for gripping and improves the ease of operation of the device. At the same time, by rotating the threaded sleeve 503, the state of the bearing rod 502 is fixed, which helps to ensure the structural stability of the bearing rod 502 after rotation adjustment.

[0053] Please see Figure 3 and Figure 8 The upper and lower ends of the support rod 502 are respectively fixed with pry bars 504 of different sizes. Each pry bar 504 is fitted with a protective cover 505 on its outer side, and the protective cover 505 is interference-fitted to the upper and lower ends of the support rod 502. During the use of this device, by installing two pry bars 504 of different sizes at the upper and lower ends of the support rod 502 respectively, the prying operation can be carried out by using the pry bars 504 during the disassembly and assembly of the aluminum alloy template, which further enhances the functionality of the device in actual use. By clamping the protective cover 505 at the upper and lower ends of the support rod 502, the pry bar 504 can be isolated and protected, which helps to ensure the safety and stability of the device in different modes of use.

[0054] Example 4

[0055] This application discloses a multi-functional hammer for installing and removing aluminum alloy formwork. Please refer to [link / reference]. Figure 1 - Figure 10 The handle 501 has a hollow structure at one end near the connecting ring 5, and a storage column 6 is slidably installed inside the hollow structure. Multiple vertically arranged storage slots 601 are distributed around the outer end wall of the storage column 6. The drill bit 301 is stored in the storage slots 601. During use, by placing the storage column 6 in the hollow structure inside the handle 501 and opening multiple storage slots 601 on the outer end wall of the storage column 6, it can be used to store drill bits 301 of different specifications. This helps to ensure the convenience of replacing and using the drill bit 301. By storing the drill bit 301, it helps to avoid losing the drill bit 301 after use.

[0056] Please see Figure 3 and Figure 9The storage slot 601 also stores a grinding rod 302. The storage slot 601 is filled with a sponge pad that wraps around the drill bit 301 and the grinding rod 302. The storage column 6 has a through-hole 602 located directly below the rotating shaft of the clamping table 3. A spring 603, elastically supported at the bottom of the storage column 6, is installed within the hollow structure. During use, by placing the grinding rod 302 in the storage slot 601, the grinding rod 302 can be replaced and installed on the clamping table 3, enabling the device to perform grinding, further enhancing its functionality in actual use. By filling the storage slot 601 with a sponge pad, the drill bit 301 and the grinding rod 302 are prevented from colliding with the inner wall of the storage slot 601 when the device is swung around. By elastically supporting the bottom of the storage column 6 with a spring 603, the position of the storage column 6 can be maintained, which helps to ensure the stability of the device during use. At the same time, by making a through hole 602 inside the storage column 6, the handle 501 can be reinstalled without disassembling after the drill bit 301 or the grinding rod 302 is installed on the clamping table 3, which helps to improve the convenience of the device during use.

[0057] Example 5

[0058] This application discloses a multi-functional hammer for installing and removing aluminum alloy formwork. Please refer to [link / reference]. Figure 1 - Figure 10 A clutch is installed between the drive shaft above the outer casing 1 and the eccentric wheel 207, and a clutch is also installed between the drive shaft below the outer casing 1 and the clamping table 3. Only one of the two clutches is in operation at any given time. Pressure sensors are installed in both connecting rings 5. During the use of this device, when the handle 501 is screwed into the upper connecting ring 5, the corresponding pressure sensor senses a signal change. At this time, the clutch transmission between the drive shaft above the motor 101 and the eccentric wheel 207 fails, and the aluminum hammer body 204 cannot move back and forth at high frequency. When the handle 501 is screwed into the lower connecting ring 5, the corresponding pressure sensor senses a signal change. At this time, the clutch transmission between the drive shaft below the motor 101 and the clamping table 3 fails, and the clamping table 3 cannot drive the drill bit 301 to rotate.

[0059] When neither of the upper nor lower pressure sensors detects a pressure change signal, i.e., the handle 501 is not installed in the upper or lower connecting rings 5, neither of the upper nor lower clutches can transmit power. By installing clutches between the drive shaft and the eccentric wheel 207 above the housing 1 and between the drive shaft and the clamping table 3 below the housing 1, and in conjunction with the pressure sensors in the upper and lower connecting rings 5, the transmission of the upper and lower clutches can be controlled according to the actual use status of the device, which helps to ensure the safety of the device during actual use.

[0060] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and its improved concept, should be covered within the scope of protection of this application.
