DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] As attached Figure 1 To Attachment Figure 4 As shown:

[0021] Embodiment 1: The utility model provides a rapping hammer with a stepless gear adjustment function, including a main body 1, including a shell 101; a gear adjustment mechanism 2, including an arc guide plate 201 arranged in the shell 101, an arc slide groove 202 respectively arranged on the arc guide plate 201 and the shell 101, a clamping hammer stopper 203 arranged on the arc guide plate 201, a hexagonal nut 204 arranged on the clamping hammer stopper 203, an adjustment rod 205 threadedly arranged on the hexagonal nut 204, and an adjustment handwheel 206 arranged at the front end of the adjustment rod 205; a rapping mechanism 3, arranged in the shell 101; and a driving mechanism 4, arranged between the rapping mechanism 3 and the shell 101.

[0022] Specifically, the arc-shaped slide groove 202 is adapted to the movement trajectory of the adjustment rod 205 .

[0023] Furthermore, the rapping mechanism 3 includes a core shaft 301 arranged in the shell 101, a driven sprocket 303 arranged on the core shaft 301, a swing arm 304 arranged on the driven sprocket 303, a hammer bearing 305 arranged at the front end of the swing arm 304, a hammer head 302 arranged on the driven sprocket 303, and a connecting bearing 307 arranged between the hammer head 302 and the driven sprocket 303.

[0024] Furthermore, a blocking plate 306 is provided on the hammer head 302 , and a groove matching with the hammer bearing 305 is provided on the blocking plate 306 .

[0025] As can be seen from the above, during operation, the driven sprocket 303 is driven to rotate on the core shaft 301 through the driving mechanism 4, and then the hammer bearing 305 is driven to move through the swing arm 304. When the hammer bearing 305 is engaged with the groove on the blocking plate 306, the hammer head 302 will be pushed to rotate with the core shaft 301 as the axis until the hammer bearing 305 contacts the clamping type hammer stopper 203. The clamping type hammer stopper 203 will generate an inward oblique thrust to it through the arc surface of the hammer bearing 305, so that it swings upward through the swing arm 304, thereby separating the hammer bearing 305 from the blocking plate 306, releasing the limit state of the hammer head 302. At this time, the hammer head 302 will rotate in the initial direction under the action of gravity due to the disappearance of resistance, so as to perform hammering and cleaning work under the action of inertia. When the hammering gear needs to be adjusted, it is only necessary to turn the adjusting hand wheel 206, and the adjusting hand wheel 206 will move forward and backward through the threaded connection between the adjusting rod 205 and the clamping type hammer removing block 203, so that the adjusting hand wheel 206 is separated from the shell 101, and the limited state of the clamping type hammer removing block 203 is released. Then, the adjusting hand wheel 206 is pushed to make it move on the arc guide plate 201 under the limiting guide of the arc slide groove 202, and then the angle of the clamping type hammer removing block 203 is adjusted. Then, the adjusting hand wheel 206 is rotated in the opposite direction to make it contact with the shell 101, so that the position of the clamping type hammer removing block 203 is limited by the contact friction force, and the gear position of the device can be easily adjusted steplessly. There is no need to disassemble the equipment when adjusting the gear position. The adjustment is fast and safe, and it is convenient for personnel to use.

[0026] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the driving mechanism 4 includes a motor 401 arranged on the top of the shell 101, a driving sprocket 402 arranged at the output end of the motor 401, and a transmission chain 403 arranged between the driving sprocket 402 and the driven sprocket 303.

[0027] Specifically, a protective shell is disposed on the top of the housing 101 outside the motor 401 , a hanging rod 102 is disposed on the top of the housing 101 and penetrates the protective shell, and a hanging ring 103 is disposed on the top of the hanging rod 102 .

[0028] As can be seen from the above, when the motor 401 is started during operation, the motor 401 will drive the active sprocket 402 to rotate, and then drive the driven sprocket 303 to rotate through the transmission chain 403, thereby reducing the rotation speed and increasing the torque, thereby stably performing the hammer cleaning work. The protective shell will shield and protect the motor 401 during operation. The staff can lift the device through the lifting ring 103, and the main tensile force can be applied to the shell 101 through the lifting rod 102, thereby improving the lifting stability.
