Description

Technical Field

[0001] The utility model specifically relates to a hammer shell component of a pile driving hammer. Background Art

[0002] Pile hammer is an indispensable and important equipment in civil engineering. It uses impact force to penetrate piles into the ground through drop hammer, diesel hammer, steam hammer, hydraulic hammer, vibratory hammer, static hammer, etc. to complete the installation of prefabricated piles. These piles can be used to build the foundation of buildings or carry out geological improvement projects. The technology of pile hammers continues to improve with economic development. Modern pile hammers can adapt to various complex construction environments and requirements.

[0003] Some pile hammers have a shackle on the top of the hammer shell to connect the pile body and transfer the impact force. For example, the Chinese invention patent application publication number "CN114892659A" discloses a turning device and turning construction method for a heavy offshore pile hammer. Figure 1 It can be seen from the content that a shackle is provided on the top of the hammer shell of the pile hammer, which is used to connect with the lifting rope of the crane to facilitate the turning of the pile hammer.

[0004] During the construction process, the hammer top shackle will mechanically collide with the hammer body and cause vibration, which may lead to pits and wear on the hammer body, and even damage to the connection between the shackle and the hammer shell, posing a safety hazard.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hammer shell assembly of a pile hammer, comprising a hammer shell, a shackle distributed on the top of the hammer shell, one end of the shackle is hinged to the hammer shell, and is characterized in that: a plurality of groups of shackle buffer pads are provided on the top of the hammer shell, and the plurality of groups of shackle buffer pads are distributed on both sides of the rotation direction of the shackle.

[0007] The above technical solution is adopted to design a shackle buffer pad to avoid mechanical collision between the shackle and the hammer shell, thereby increasing the service life of the shackle and the hammer shell and increasing the safety of use. When the other end of the shackle buffer pad rotates around the hinge between the shackle and the hammer shell until it is close to the hammer shell, the shackle buffer pad is distributed on both sides of the shackle rotation direction, thereby replacing the shackle and the hammer shell to collide, protecting the hammer shell and the shackle.

By setting a mounting seat, the stability is enhanced. The mounting seat serves as a support point, which can effectively disperse the force applied to the shackle during use, reduce the impact on the hammer shell, and thus extend the service life. The hinged design of the pin shaft and the mounting seat makes the connection between the shackle and the hammer shell more firm and reliable. During use, even if it is subjected to a large external force impact, it can maintain a firm connection, reduce the risk of accidental detachment, and thus improve the safety performance of the entire device.

[0018] The above-mentioned hammer shell assembly of a pile hammer can be further configured as follows: the shackle includes a main body part and a rotatable connecting part, the main body part includes two groups of symmetrical and spaced-apart buckling bodies, the connecting part is arranged on the outside of the buckling body and can rotate relative to the main body part, and the connecting part is semicircular.

[0019] By adopting the above technical solution, two sets of symmetrical and spaced buckle bodies are used to make the entire shackle structure more balanced, the force distribution more even, and the risk of deformation or damage caused by uneven force is reduced. The semicircular design of the connecting part is not only beautiful, but also conforms to engineering principles. The semicircular structure helps to disperse the force and increase the strength and durability of the shackle; in addition, the semicircular design is also conducive to better grip and operation by users, improving the convenience of use.
