[0004] This technology has certain defects: during operation, the pile hammer often needs to move from one place to the next piling point. There is no quick separation structure between the landing gear and the hammer body of this technology. The separation or assembly of the landing gear and the hammer body is very cumbersome. At the same time, if the pile slips, the landing gear and the hammer body are not separated quickly, and the pile frame of the crane will be subjected to excessive tension, which will cause damage to the pile frame and cause the pile frame to be subjected to excessive tension and break. Therefore, there is still room for improvement in this technology. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a landing gear for a pile hammer in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a landing gear for a pile driver, the landing gear includes a shell, and is characterized in that: the landing gear also includes a lever and a hammer block, the lever is hinged to the shell, the hammer block is provided with a first movable groove, the end of the lever is distributed in the first movable groove and is linked with the first movable groove, the shell is provided with a second movable groove, and the hammer block is distributed at the end of the second movable groove to enable the hammer block to slide axially in the second movable groove.

[0007] By adopting the above technical scheme, the lever is linked with the hammer block, and the hammer block is installed on the matching pile driving hammer body. When the landing gear lifts the hammer body, the abutment block and the lever play a load-bearing role together. When separated, the lever is swung, and the shell is provided with a first movable groove. The lever is located in the first movable groove to lift the hammer block. At the same time, the shell is provided with a second movable groove so that the hammer block can be lifted or dropped by sliding the lever. The lever lifts the hammer block, and when it is lifted to a certain angle, the lever disengages from the first movable groove, so that the lever is separated from the hammer block. The hammer block is installed on the matching pile driving hammer body, so as to achieve the purpose of quickly separating the landing gear from the hammer body.

[0008] The above-mentioned landing gear of a pile hammer can be further configured as follows: the shell is provided with an abutment block, the lever is passed through the first movable groove, the end of the lever connecting the landing gear and the hammer body abuts against the first movable groove, and the bottom of the lever abuts against the abutment block.

[0009] By adopting the above technical solution, when the landing gear is connected to the hammer body, the lever is inserted into the first movable groove so that the end of the lever abuts against the first movable groove, and the bottom of the lever abuts against the abutment block. The landing gear lifts the hammer body, and the hammer body abuts against the lever through the first movable groove of the hammer lifting block. The bottom of the lever bears the weight together through the abutment block. The hammer lifting block is connected to the hammer body of the pile driving hammer, and the end of the lever abutting against the first movable groove is lifted. When it is lifted to a certain angle, the lever can be separated from the first movable groove, and the landing gear is separated from the hammer body.

[0010] The above-mentioned landing gear of a pile driver can be further configured as follows: the shell is provided with a connecting pile, the lever is provided with a connecting hole, the connecting hole is sleeved on the connecting pile, the connecting pile is also sleeved with a connecting block of a limiting lever, and the lever is connected to the shell through the connecting pile and the connecting hole.

[0015] By adopting the above technical solution, the rotation angle of the pull rod is limited by the limit block. If the rotation angle of the pull rod is too large, it will easily cause excessive stress on the lever or the structural parts connected to it, thereby causing deformation or even breakage. At the same time, it will also operate the pull rod beyond the reset angle, making the pull rod unable to reset. The setting of the limit block can ensure the stable linkage of the structure.

[0016] The above-mentioned undercarriage of a pile hammer may be further configured as follows: the shell is provided with a reinforcement block fixedly connected to the abutment block.

[0017] By adopting the above technical solution, the shell is also provided with a reinforcement block for reinforcing the abutment block. Since the abutment block and the lever bear the weight from the hammer body, the provision of the reinforcement block can improve the load-bearing capacity of the abutment block, making the device more stable and safe.

[0018] The above-mentioned undercarriage of a pile hammer may be further configured as follows: the housing is provided with a plurality of connecting plates at the lever, and the connecting plates are fixedly connected with cover plates.

[0019] By adopting the above technical solution, a plurality of connecting plates are provided on the housing at the lever, and these connecting plates can reinforce the housing and enable the modified version to be installed at the lever, thereby protecting the internal parts and increasing the service life of the machine.

[0020] The above-mentioned undercarriage of a pile hammer may be further configured as follows: the shell is provided with a plurality of handrails for mounting the external guide rails.

[0021] By adopting the above technical solution, the shell is equipped with handrails, which can be connected to the guide rails of the external pile frame, and the installation position of these handrails can be adjusted.

[0022] The beneficial effects of the utility model are as follows: the lever is linked with the hammer block, the lever is located in the first movable groove to lift the hammer block, and at the same time the shell is provided with a second movable groove so that the hammer block can be lifted or dropped by the lever, the lever lifts the hammer block, and when it is lifted to a certain angle, the lever disengages from the first movable groove, so that the lever is separated from the hammer block, and the hammer block is installed on the matching pile hammer hammer body, so as to achieve the purpose of quickly separating the landing gear from the hammer body.
