Description
Technical Field
[0001] This application relates to the technical field of demolition hammers, and in particular to a wall demolition hammer with a buffer device. Background Technology
[0002] In building demolition operations, wall demolition hammers are a commonly used tool, widely used for breaking concrete or brick walls. This tool breaks walls through high-frequency impact, thereby improving construction efficiency. However, most of the existing mainstream demolition hammers adopt a direct impact structure, which generates a large recoil force during operation, making operators prone to fatigue and even injury during prolonged use.
[0003] In recent years, some manufacturers have begun to introduce cushioning structures into demolition hammers to reduce the impact on the operator. Currently, most cushioning technologies are mainly focused on the design of shock-absorbing handles. Although they can reduce the impact on the hand to some extent, they have limited effect on reducing the strong impact generated by the tool body. Moreover, this complex cushioning structure increases manufacturing costs and affects the product's market competitiveness.
[0004] Therefore, given the limitations and shortcomings of existing technologies, there is an urgent need for an improved solution that can effectively absorb the impact force of the tool body to enhance operator comfort and safety, while also taking into account manufacturing costs and usage effectiveness. Utility Model Content
[0005] In order to overcome the lack of an improved solution for existing wall demolition hammers that can effectively absorb the impact force of the tool body to improve the operator's comfort and safety, while taking into account the manufacturing cost and the effect of use, this application provides a wall demolition hammer with a buffer device.
[0006] The wall demolition hammer with a buffer device provided in this application adopts the following technical solution: A wall demolition hammer with a buffer device includes a support, a buffer, and a fixing component. The support includes a support frame with rollers rotatably connected to both ends. A fixing frame is vertically fixed to the center of the top surface of the support frame. The buffer includes a lifting frame with two damping rods horizontally fixed to one end. Buffer springs are horizontally sleeved on the output ends of the two damping rods, and both ends of the buffer springs are fixed to the damping rods and the lifting frame, respectively. The other ends of the outer walls of the two damping rods are fixedly assembled to the fixing frame. The fixing component includes a connecting frame plate vertically assembled on the top surface of the lifting frame. A cylinder seat is vertically and adjustablely assembled above the connecting frame plate, and the impact hammer body is horizontally fixedly installed on the top surface of the cylinder seat.
[0007] By adopting the above technical solution, the support component provides overall structural support, allowing the wall demolition hammer to be stably supported at the location where the wall needs to be demolished. Its rollers at both ends can roll flexibly during operation to adapt to different working environments. The buffer component, assembled with a support frame and damping rod, with the other end of the damping rod fixed to the top of the support frame, effectively absorbs impact force, reducing vibration of the hammer body during operation, thereby protecting the equipment and extending its service life. The connecting frame plate and cylinder seat in the fixing component ensure the safe installation and adjustment of the hammer body, allowing it to be precisely aligned with the wall according to actual needs, improving work efficiency. The wall demolition hammer is fixed in the working position by the support component. The buffer spring and damping rod in the buffer component provide a cushioning effect when impacted, reducing the impact force and mitigating the impact on the external environment. The power transmission path of the hammer body during impact is buffered by the buffer component, effectively protecting the structural integrity of the equipment and the safety of the operator, while improving the stability and safety of the operation process.
[0008] Optionally, the outer wall of the damping rod is horizontally fixed with a hole seat, and multiple ear seats are vertically fixed on the top surface of the lifting frame.
[0009] By adopting the above technical solution, horizontal holes are fixed on the outer wall of the damping rod, mainly to provide positions for installing fixing bolts, so as to achieve a fixed connection between the fixing frame and the damping rod. Multiple lugs are vertically fixed on the top surface of the lifting frame, mainly to provide threaded installation positions for locking screws, ensuring a tight connection between the connecting frame plate and the lifting frame.
[0010] Optionally, the top of the fixed frame has a horizontal thread through which multiple fixing bolts are assembled, and the multiple fixing bolts on the fixed frame are threaded into the holes of the damping rod.
[0011] By adopting the above technical solution, the fixed frame achieves a fixed connection with the damping rod's hole seat through multiple fixing bolts via the horizontal thread at the top, ensuring a tight and stable connection during movement.
[0012] Optionally, the bottom of the connecting plate is threaded with a locking screw, and the locking screw is threaded into the lug of the lifting frame.
[0013] By adopting the above technical solution, multiple locking screws are assembled at the bottom of the connecting frame plate through a threaded connection, thereby firmly fixing the connecting frame plate in the ear seat of the lifting frame, achieving the stability and reliability of the overall structure.
[0014] Optionally, a guide cylinder is vertically fixed on the bottom surface of the cylinder base, and two clamps are vertically and symmetrically arranged on the top surface of the cylinder base. The impact hammer body is horizontally clamped between the two clamps, and the adjacent ends of the two clamps are locked together by screws.
[0015] By adopting the above technical solution, a guide cylinder is installed on the bottom surface of the cylinder base to guide the vertical sliding of the connecting frame plate. Two clamps are symmetrically arranged on the top surface of the cylinder base for horizontally engaging and assembling the impact hammer body. The clamps can be locked by rotating the screws, further fixing the position of the impact hammer body. Overall, this device achieves precise vertical adjustment of the impact hammer body through the sliding of the connecting frame plate in the guide cylinder and the threaded engagement of the screw and the solenoid, ensuring that the impact hammer can be adjusted in position as needed to meet the requirements of different working conditions.
[0016] Optionally, a guide post is vertically fixed on the top surface of the connecting frame plate, and the guide post is vertically slidably inserted into the guide cylinder on the bottom surface of the cylinder seat. A screw is vertically fixed on the top surface of the connecting frame plate, and a screw tube is vertically rotatably connected on the bottom surface of the cylinder seat, and the screw tube and the screw are threadedly assembled and connected.
[0017] By adopting the above technical solution, the guide post is fixed on the top surface of the connecting frame plate and cooperates with the guide cylinder on the bottom surface of the cylinder base to ensure that the connecting frame plate can slide up and down in the vertical direction. The screw fixed on the top surface of the connecting frame plate is rotatably connected to the threaded pipe on the bottom surface of the cylinder base. By rotating the screw, the height of the connecting frame plate can be adjusted, thereby realizing the vertical position adjustment of the impact hammer body.
[0018] Optionally, both sides of the support frame are horizontally fixed with anchor plates, and anchor nails are vertically inserted through the anchor plates.
[0019] By adopting the above technical solution, the support frame serves as the main structural support, ensuring the overall stability of the equipment; the anchor plates on both sides increase the lateral fixation of the bracket, and the anchor nails fix it to the foundation, preventing the lateral movement of the equipment.
[0020] Optionally, a hinged bracket is horizontally hinged at the middle of the support frame, and the handle of the hinged bracket is fitted with a rubber sleeve.
[0021] By adopting the above technical solution, the articulated support frame is horizontally hinged in the middle of the support frame, allowing for flexible adjustment of the equipment's support state during operation, enhancing the equipment's adaptability and making it more convenient to use. The rubber sleeves on the articulated support frame handles enhance the grip and anti-slip performance during operation, improving user safety and comfort. In summary, the coordinated work of all components forms a stable yet flexible support system, ensuring the stability and safety of the equipment during use, and enhancing both operational convenience and safety.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.
[0026] This application discloses a wall demolition hammer with a buffer device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4A wall demolition hammer with a buffer device includes a support 1, a buffer 2, and a fixing 3. The support 1 includes a support frame 11, with rollers 111 rotatably connected to both ends of the support frame 11, and a fixing frame 12 vertically fixed to the middle of the top surface of the support frame 11. The buffer 2 includes a lifting frame 21, with two damping rods 22 horizontally fixed to one end of the lifting frame 21, and buffer springs 23 horizontally sleeved at the output ends of the two damping rods 22. The two ends of the buffer springs 23 are respectively fixed to the damping rods 22 and the lifting frame 21. The other ends of the outer walls of the two damping rods 22 are fixedly assembled with the fixing frame 12. The fixing 3 includes a connecting frame plate 31, which is vertically assembled on the top surface of the lifting frame 21. A cylinder seat 32 is vertically adjustable and assembled above the connecting frame plate 31. An impact hammer body 37 is horizontally fixedly installed on the top surface of the cylinder seat 32.
[0027] By adopting the above technical solution, the support component 1 can provide overall structural support, enabling the wall demolition hammer to be stably supported at the location where the wall needs to be demolished. Its two end rollers 111 can roll flexibly during operation to adapt to different working environments. The buffer component 2 is assembled with the lifting frame 21 and the damping rod 22, with the other end of the damping rod 22 fixed to the top of the support frame 11. This effectively absorbs impact force, reducing the vibration of the hammer body 37 during operation, thereby protecting the equipment and extending its service life. The connecting frame plate 31 and the cylinder seat 32 in the fixing component 3 ensure the safe installation and adjustment of the hammer body 37, allowing it to be precisely aligned with the wall according to actual needs, improving work efficiency. In terms of working principle, the wall demolition hammer is fixed in the working position by the support component 1. The buffer spring 23 and the damping rod 22 in the buffer component 2 generate a buffering effect when impacted, reducing the impact force and mitigating the impact on the external environment. The power transmission path of the impact hammer body 37 during impact is buffered by the buffer 2, which effectively protects the structural integrity of the equipment and the safety of the operator, while improving the stability and safety of the operation process.

The horizontally fixed seat 221 on the outer wall of the damping rod 22 is mainly used to provide positions for installing fixing bolts to achieve a fixed connection between the fixed frame 12 and the damping rod 22. Multiple lugs 211 are vertically fixed on the top surface of the lifting frame 21, mainly used to provide threaded installation positions for locking screws 311 to ensure a tight connection between the connecting frame plate 31 and the lifting frame 21. Multiple fixing bolts are threaded through the top of the fixed frame 12, and the multiple fixing bolts on the fixed frame 12 are threaded into the seat 221 of the damping rod 22. The fixed frame 12 achieves a fixed connection with the seat 221 of the damping rod 22 through the horizontally threaded bolts at the top, ensuring a tight and stable connection during movement. The bottom of the connecting frame plate 31 is threaded with locking screws 311, which are threaded into the lugs 211 of the lifting frame 21. Multiple locking screws 311 are threaded through the bottom of the connecting frame plate 31, thus firmly fixing the connecting frame plate 31 to the lugs 211 of the lifting frame 21, achieving overall structural stability and reliability.
[0029] Reference Figure 5 A guide cylinder is vertically fixed to the bottom surface of the cylinder base 32, and two clamps 36 are vertically and symmetrically arranged on the top surface of the cylinder base 32. The two clamps 36 are horizontally engaged with the impact hammer body 37, and the adjacent ends of the two clamps 36 are locked together by screws. The guide cylinder installed on the bottom surface of the cylinder base 32 is used to guide the sliding of the connecting frame plate 31 in the vertical direction. The two clamps 36 are symmetrically arranged on the top surface of the cylinder base 32 for horizontally engaging the impact hammer body 37. The clamps 36 can be locked by rotating the screws, further fixing the position of the impact hammer body 37. Overall, this device achieves precise vertical adjustment of the impact hammer body 37 through the sliding of the connecting frame plate 31 in the guide cylinder and the threaded engagement of the screw 34 and the solenoid 35, ensuring that the impact hammer can be adjusted to meet the needs of different working conditions. A guide post 33 is vertically fixed to the top surface of the connecting frame plate 31, and the guide post 33 is vertically slidably inserted into the guide cylinder on the bottom surface of the cylinder seat 32. A screw 34 is vertically fixed to the top surface of the connecting frame plate 31, and a screw tube 35 is vertically rotatably connected to the bottom surface of the cylinder seat 32, and the screw tube 35 is threadedly assembled with the screw 34. The guide post 33 is fixed to the top surface of the connecting frame plate 31 and cooperates with the guide cylinder on the bottom surface of the cylinder seat 32 to ensure that the connecting frame plate 31 can slide up and down in the vertical direction. The screw 34 fixed to the top surface of the connecting frame plate 31 is threadedly assembled with the screw tube 35 rotatably connected to the bottom surface of the cylinder seat 32. By rotating the screw 34, the height of the connecting frame plate 31 can be adjusted, thereby realizing the vertical position adjustment of the impact hammer body 37.
[0030] Reference Figure 3Anchor plates 13 are horizontally fixed on both sides of the support frame 11, and anchor nails 14 are vertically inserted through the anchor plates 13. The support frame 11 serves as the main structural support, ensuring the overall stability of the equipment; the anchor plates 13 on both sides increase the lateral fixation of the bracket, and are fixed to the foundation by the anchor nails 14, preventing lateral movement of the equipment.
[0031] Reference Figure 3 A hinged bracket 15 is horizontally hinged to the middle of the support frame 11, and the handle of the hinged bracket 15 is covered with a rubber sleeve. The horizontal hinge of the hinged bracket 15 in the middle of the support frame 11 allows for flexible adjustment of the equipment's support state during operation, enhancing the equipment's adaptability and making it more convenient to use. The rubber sleeve on the handle of the hinged bracket 15 enhances the grip and anti-slip performance during operation, improving user safety and comfort.
[0032] The implementation principle of a wall demolition hammer with a buffer device in this application embodiment is as follows: First, the fixed connecting frame 12 of the support frame 11 in the support member 1 is fixedly assembled with the hole seat 221 on the damping rod 22 in the buffer member 2 by fixing bolts, thus completing the fixed assembly of the buffer member 2 and the support member 1. Then, the connecting frame plate 31 in the fixing member 3 is fixedly assembled on the support frame 11 by locking screws 311. Then, the impact hammer body 37 is clamped onto the top surface of the cylinder seat 32 by two clamps 36, thus completing the vertical assembly and connection of the support member 1, the buffer member 2 and the fixing member 3 from bottom to top. Then, the vibration generated by the impact hammer body 37 breaking through the wall causes the lifting frame 21 to move horizontally, pulling the damping rod 22 to extend and the shock absorber spring 23 to deform, absorbing the vibration generated by the impact hammer body 37 breaking through the wall. The deformation potential energy of the shock absorber spring 23 is offset by the restoring damping force of the damping rod 22, ensuring the stability of the impact hammer body 37 in breaking through the wall.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
