Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a pile hammer lifting device for protecting a pile frame track. Background Art

[0002] As an important construction machine of pile-driving ships, hydraulic pile hammer uses hydraulic energy and its own weight to drive pile foundation into the seabed. It is widely used in offshore pile foundation construction due to its energy saving, environmental protection, low noise and vibration, and high efficiency.

[0003] The pulley box of the pile hammer is the core equipment of the pile-driving ship construction. It is mainly used to raise and lower the pile hammer during the pile driving work. The pulley box is connected to the pile hammer through the hammer wire rope, and the pulling force of the crane is transmitted to the pile hammer, so that the pile hammer can generate enough impact force to drive the pile into the ground; in the process of hanging cement piles, the pile hanging wire rope in the pile hanging equipment is spirally wound around the outer wall of the cement pile body, and then fixed by the hooks between the wire ropes to ensure the stability of the pile body. However, after the pile body is stable, the hook on the pile is untied, and the hook will drive the wire rope to fly out in a circle due to inertia. At this time, the impact force generated by the retraction of the hook can easily cause damage to the pile frame, thereby preventing the pile hammer from rising and falling normally; at the same time, when driving the inverted pile, due to the lack of limit on the pile hanging wire rope, the pile hanging wire rope will enter the pile frame, causing wear on the pile frame and reducing the service life of the pile frame. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a device for protecting the track of the pile frame in a pile hammer, which can extend the service life of the pile frame and ensure the operation of the pile hammer, in view of the above-mentioned deficiencies in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pile hammer lifting device for protecting a pile frame track, comprising a pile frame track, a pulley box is installed on the pile frame track, and the pulley box can be reciprocated along the pile frame track by an external crane, and the bottom of the pulley box is connected to the top of the pile hammer body, and is characterized in that: the pulley box includes an armrest seat installed with the pile frame track, and baffles are arranged on both sides of the armrest seat, the baffles are located between the pile frame track and the pile hammer body, and the baffles can block the pile hanging wire rope on the side of the baffle away from the pile frame track.

[0006] The above technical scheme is adopted: compared with the prior art that during the pile hanging process, after the pile body is stably unbuckled, the pile hanging hook retracts and causes damage to the pile frame. The utility model provides baffles on both sides of the pulley hanging box, which can block the upper end of the pile hanging wire rope on the side of the baffle away from the pile frame track, so that when the pile hanging hook is unbuckled, the baffle can buffer the impact force of the retraction of the pile hanging wire rope, offset some of the impact force, reduce the damage of the pile hanging wire rope to the pile frame track, and extend its service life. At the same time, when driving the pile, the baffle can block the pile hanging wire rope to prevent the pile hanging wire rope from entering the pile frame.

[0007] A further configuration of the utility model is that the armrest seat is penetrated by a first mounting hole and a second mounting hole for inserting each baffle rod, and the two are parallel to each other, and the baffle rods are respectively installed on different sides of the first mounting hole and the second mounting hole.

[0008] The above technical solution is adopted: by setting the first and second mounting holes, it is convenient for workers to assemble the baffle rod and the armrest seat. The workers only need to align the end of the baffle rod with the mounting hole and then install it, thereby improving assembly efficiency.

[0009] The utility model is further configured as follows: the barrier rod comprises a mounting rod and an adjusting rod, the adjusting rod is slidably connected to an end of the mounting rod away from the armrest seat, the mounting rod is provided with a plurality of first adjusting holes, the adjusting rod is provided with a plurality of second adjusting holes corresponding to the first adjusting holes, and the end of the adjusting rod away from the mounting rod is provided with a limit block extending in a direction away from the pile frame track

[0010] The above technical solution is adopted: since there is a platform window on the top of the pile frame, when the barrier rod is too long, the barrier rod cannot pass through the platform window, so some longer piles cannot be driven. Therefore, through the setting of the mounting rod and the adjusting rod, the length of the barrier rod can be adjusted. The staff only needs to slide the adjusting rod toward the inside of the mounting rod in advance, and make the first and second adjusting holes correspond to each other, and connect them through the first and second adjusting holes with fasteners to complete the adjustment of the length of the barrier rod, so that the barrier rod can pass through the platform window, thereby improving its versatility. In addition, when the adjusting rod is broken or worn during long-term use, the structure is also easy to replace.

[0011] A further configuration of the utility model is that at least four clamps are sequentially spaced apart near one end of the armrest seat near the pile frame track, one end of the clamp is mounted on the armrest seat by bolts, the other end of the clamp is provided with a sliding groove which can be engaged with the pile frame track, and the clamp can reciprocate along the pile frame track through the sliding groove, and the inner wall of the sliding groove is provided with a wear-resistant pad.

[0012] The above technical solution is adopted: through the setting of the clamping plate and the sliding groove, the armrest seat can be installed on the pile frame track, and at the same time, the armrest seat can be driven by an external crane to reciprocate along the pile frame track through the sliding groove, further driving the pile hammer body to rise and fall, and at the same time, due to the setting of the wear-resistant pad on the inner wall of the sliding groove, wear in the sliding groove is prevented, thereby affecting the sliding effect.

[0013] A further configuration of the utility model is that a pulley block is further provided at one end of the handrail seat away from the pile frame track, the pulley block comprises a shell and a plurality of guide pulleys installed in the shell, the guide pulley can guide the hammer wire rope in the external crane, at least two first connecting ear blocks are provided at the bottom of the shell, and a second connecting ear block corresponding to the first connecting ear block is provided at the top of the pile hammer body.

[0014] The above technical solution is adopted: through the setting of the guide pulley, one end of the hammer hanging wire rope in the external crane is connected to the crane, and the other end is connected to the upper end of the pile hammer body through the guide pulley. The guide pulley facilitates the guidance of the hammer hanging wire rope and reduces the friction of the wire rope, so that the pile hammer can be lifted and lowered more smoothly; in addition, through the setting of the first and second connecting ear blocks, the installation firmness and stability between the pulley hanging box and the pile hammer body are improved, so that the pulley hanging box can drive the pile hammer body to be lifted and lowered.
