Description

Technical Field

[0001] This utility model relates to the field of chipping hammer technology, and in particular to a long-rod pneumatic chipping hammer for precast beam flange plates. Background Technology

[0002] The long-bar pneumatic chisel hammer for precast beam flange slabs is a tool used for chiseling the concrete surface of precast beam flange slabs. Driven by compressed air, it features high efficiency and convenience, and can improve the construction quality of the interface between new and old concrete. It typically consists of a handle, cylinder, piston, and chisel head. Powered by compressed air, the compressed air is distributed alternately to the two heads of the cylinder by the piston's position change during movement, causing the piston to perform a reciprocating impact motion. This motion is transmitted to the punch connected to the small cone of the piston, thereby hammering the workpiece surface to achieve the chiseling function.

[0003] Existing chiseling hammers, when chiseling, generate high-speed impacts from the punch, which, while achieving the effect of chiseling concrete slabs, also cause some concrete debris to fly out, which can injure workers and pose a safety hazard. To address this, we propose a long-bar pneumatic chiseling hammer for precast beam flange slabs. Utility Model Content

[0017] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 like Figure 1-4 As shown, a pneumatic chisel hammer for a precast beam flange includes a frame 1, an air compressor 2 on the frame 1, multiple air supply pipes 3 connected to the output end of the air compressor 2, and the other end of the air supply pipes 3 connected to the chisel head 4. A connecting frame 5 is slidably connected inside the frame 1, and the connecting frame 5 and the chisel head 4 are detachably connected by a connecting assembly. A receiving groove 11 is provided on the side of the frame 1 facing the chisel head 4.

[0019] In practical use, with the setup of air compressor 2, air supply pipe 3, chisel head 4, connecting frame 5, connecting assembly, electric push rod 7 and receiving groove 11, when chiseling work is being carried out, the worker can start the electric push rod 7, which will retract the chisel head 4 into the receiving groove 11. The air compressor 2 will be started, and the gas will be transmitted through the air supply pipe 3 to enable the chisel head 4 to start working. Due to the shielding effect of the receiving groove 11, it can effectively prevent debris from flying towards the worker during the chiseling process, thus improving safety. Furthermore, when not in use, retracting the chisel head 4 into the receiving groove 11 can effectively prevent the chisel hammer from bumping or hitting the chisel head 4 during transportation.

[0020] In this embodiment, a groove 6 is provided at the bottom of the frame 1, and the connecting bracket 5 is slidably connected inside the groove 6.

[0021] In practical use, the slide 6 can limit the connecting frame 5, ensuring that the connecting frame 5 moves more smoothly inside the slide 6.

[0022] In this embodiment, an electric push rod 7 is fixedly installed on the inner wall of the slide 6. One end of the electric push rod 7 is fixedly connected to the connecting frame 5. A storage battery is installed on the frame 1 to provide power to the electric push rod 7 and the air compressor 2.

[0023] In practical use, the stroke of the electric push rod 7 is matched with the length of the slide 6. The length of the slide 6 is slightly longer than the stroke of the electric push rod 7, ensuring that after the electric push rod 7 is fully extended, the connecting frame 5 still retains a section inside the slide 6, making the connecting frame 5 more stable.

[0024] In this embodiment, the connecting component includes a limiting seat 8, a connector 9 is inserted into the limiting seat 8, the limiting seat 8 is fixedly connected to the connecting frame 5, the connector 9 is fixedly connected to the chisel head 4, and the connector 9 and the limiting seat 8 are fixedly connected by bolts 10 after installation.

[0025] In practical use, when one of the chisel heads 4 is damaged, the operator can activate the electric push rod 7. The electric push rod 7 pushes the connecting frame 5 to move inside the slide 6, pushing the chisel head 4 out of the receiving groove 11 and releasing the bolt 10 from the locking of the connecting head 9, making it easier and faster to replace the damaged chisel head 4.

[0026] In this embodiment, a rotating shaft is rotatably connected inside the frame 1, and movable wheels 13 are fixedly connected to both ends of the rotating shaft. A support rod is provided on the frame 1, and a handle is provided on the side of the support rod facing the worker. A control switch is provided on the support rod, and the control switch is electrically connected to the electric push rod 7 and the air compressor 2 through a wire.

[0027] In practical use, when workers are doing roughening work, they can pull the device to move and roughen the surface at the same time, which is more labor-saving and has better roughening efficiency. The control switch is located at a distance from the handle, making it easy for workers to start and stop the control switch.

[0028] In this embodiment, a protective mesh cover 12 is provided on the outside of the air compressor 2.

[0029] In practical use, the protective net cover 12 can protect the air compressor 2, blocking large particles of debris from entering, and its breathable design helps the air compressor 2 dissipate heat during operation. The frame 1 is equipped with a protective canopy, which can shield and protect the air compressor 2, reduce the damage caused by debris falling from the top, and also serve as a rainproof function.

[0030] Working principle: When performing chipping work, the operator can activate the electric push rod 7, which will retract the chipping head 4 into the receiving groove 11. The air compressor 2 will be activated, and the gas will be transmitted through the air supply pipe 3 to start the chipping head 4. Due to the shielding of the receiving groove 11, it can effectively prevent the chips from flying towards the operator during the chipping process, thus improving safety. When not in use, the chipping head 4 can be retracted into the receiving groove 11, which can effectively prevent the chipping hammer from bumping or hitting the chipping head 4 during the transportation process. When one of the chisel heads 4 is damaged, the operator can activate the electric push rod 7. The electric push rod 7 pushes the connecting frame 5 to move inside the slide 6, pushing the chisel head 4 out of the receiving groove 11 and releasing the bolt 10 from the locking of the connecting head 9, making it easier and faster to replace the damaged chisel head 4.
