Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a hydraulically controlled pile hammer handrail. Background Art

[0002] The hammer shell of the existing pile hammer on the market is welded with a clamp corresponding to the dragon mouth track. After the clamp clamps the dragon mouth track, it drives the pile hammer to move up and down along the dragon mouth track without deviation to the left or right. However, as the pile body is getting bigger and bigger, the pile cap will also increase accordingly. The pile cap will affect the smooth movement of the pile hammer on the dragon mouth track. Therefore, when manufacturing the hammer shell, the customer will provide the center distance between the center of the hammer shell and the track, and let the factory customize the corresponding clamp according to this parameter. However, this method means that the welded hammer shell can only be used for a single project. If it needs to be reused for another project, the clamp needs to be unsoldered, which not only affects the strength of the hammer shell connection, but also is labor-intensive and time-consuming. The disassembled clamp is scrapped, causing great waste.

[0003] In order to solve the above problems, the applicant has applied for a claw mechanism suitable for pile frame type piling equipment with publication number "CN217480159U", including an armrest seat fixedly arranged on the outer peripheral surface of the hammer shell and two corresponding dragon mouth clamps, a transition bracket is provided between the armrest seat and the dragon mouth clamp, one end of the transition bracket is connected to the armrest seat through a first detachable structure, and the other end is connected to the two dragon mouth clamps to form a clamping jaw for clamping the dragon mouth rail, the dragon mouth clamp is connected to the transition bracket through a second detachable structure, and the dragon mouth clamps are provided with dragon mouth claws corresponding to the fixed supporting claws, and the clamping jaws are formed between the dragon mouth claws and the fixed supporting claws.

[0004] It can be seen from the above documents that the handrail and the dragon mouth track in the existing pile hammer claw mechanism are installed with each other through bolts or pins. After the installation is completed, the dragon mouth track is connected to the pile body. This installation method has low assembly efficiency and is relatively dangerous and difficult for the installation of the handrail. Summary of the invention
