Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a pile hammer with a detachable pile cap. Background Art
[0002] A hydraulic pile hammer is an impact piling machine that strikes the pile body mainly by free fall. After being raised to the desired height by the hydraulic system, it obtains acceleration energy from the hydraulic system to increase the impact speed to strike the pile body.
[0003] When piling is officially started, it is often necessary to feed the pile first. In the piling construction, feeding the pile is an important step, which involves accurately placing the prefabricated pile body at a predetermined position for subsequent pressing or driving operations. However, in the existing pile hammer, since the pile cap and the hammer body are fixedly connected by bolts, during the pile feeding process, when the prefabricated pile is inserted into the pile cap, the weight of the entire hammer body may be pressed on the prefabricated pile. At this time, the pile hanging device cannot bear this weight and will break, thereby posing a safety hazard. Summary of the invention
[0004] The technical problem to be solved by the utility model is to provide a pile driving hammer with a detachable pile cap, which can prevent the pile hanging device from being broken due to being unable to bear the weight of the whole hammer during the pile feeding process, in view of the deficiencies of the above-mentioned prior art.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pile hammer with a detachable pile cap, comprising a pile frame guide rail, the pile frame guide rail is provided with at least two groups of hammer handrail mechanisms and a pile cap handrail mechanism located below the hammer handrail mechanism, the hammer handrail mechanism is installed with a hammer assembly on the side away from the pile frame guide rail, and the pile cap handrail mechanism is installed with a pile cap on the side away from the pile frame guide rail, characterized in that a detachable connecting structure is provided between the pile cap and the hammer assembly; one end of the detachable connecting structure is connected to the outer wall of the hammer assembly, and the other end is connected to the top of the pile cap, so as to form a gap between the pile cap and the hammer assembly.
[0006] Adopting the above technical scheme: Compared with the prior art in which the pile cap and the hammer body are both connected by bolts, the utility model uses a detachable connection structure to enable the pile cap to be suspended under the hammer body. During the pile feeding process, after the prefabricated pile is inserted into the pile cap, the weight of the hammer body does not act on the pile, thereby avoiding the situation where the pile hanging device cannot bear the weight of the whole hammer and breaks, thereby improving safety.
[0007] A further configuration of the utility model is that the detachable connection structure comprises at least two chains, the upper ends of the chains are detachably connected to the hammer assembly, the lower ends are detachably connected to the pile cap, and the chains are symmetrically arranged with each other.
[0008] The above technical solution is adopted: through the setting of the chain, the pile cap can be suspended below the hammer assembly. When feeding the pile, it is only necessary to put the pile into the pile cap to achieve that the weight of the hammer does not act on the pile. At the same time, due to the detachable setting of the chain, after the pile feeding is completed, the formal piling process begins. The hammer handrail mechanism drives the hammer assembly to move downward toward the pile cap. When the hammer assembly is against the top of the pile cap, the chain is removed and the piling can be normally performed.
[0009] The utility model is further configured as follows: a first connecting block corresponding to the lower end of the chain is provided at the top of the pile cap, a first through hole is provided on the first connecting block, a connecting buckle for mounting the lower end of the chain is provided at the first through hole, a second connecting block corresponding to the upper end of the chain is provided at the outer end of the hammer assembly, a second through hole is provided on the second connecting block, and a connecting buckle for mounting the upper end of the chain is provided at the second through hole.
[0010] By adopting the above technical solution: through the provision of the first and second connecting blocks and the connecting shackles, both ends of the chain are connected to the corresponding connecting shackles. When the chain needs to be disassembled, it is only necessary to open and remove the connecting shackles at both ends to complete the disassembly, which is convenient for the staff to disassemble.
[0011] The utility model is further configured as follows: the connecting buckle comprises an arched portion; the two ends of the arched portion are parallel to each other, and buckle arms are respectively provided at the two ends, the buckle arms are provided with button holes corresponding to the first through holes, and detachable bolts are provided in the button holes and the first through holes.
[0012] The above technical solution is adopted: through the arrangement of the bow portion, the buckle arm, the button eye and the detachable bolt, when the chain needs to be installed, one end of the chain is inserted into the bow portion between the buckle arms at both ends, the button eye is aligned with the first through hole, the detachable bolt is inserted, and the two are connected to achieve installation.
[0013] A further configuration of the utility model is that the hammer armrest mechanism includes an armrest seat and a dragon mouth splint, one end of the armrest seat is installed with the outer wall of the hammer assembly, and the other end is connected with the dragon mouth splint by bolts, and the dragon mouth splint can be engaged and connected with the pile frame guide rail and can reciprocate along the pile frame guide rail.
[0014] The above technical solution is adopted: through the setting of the handrail seat and the dragon mouth clamp, when the pile feeding is completed and formal piling is required, the hammer handrail mechanism can drive the hammer assembly to move along the pile frame track toward the pile cap until it hits the top of the pile cap, and then the chain and the hanger are removed to achieve normal piling function.
[0015] The utility model is further configured as follows: the hammer assembly includes a shell and a hammer core located in the shell, the bottom of the shell is connected to a buffer chamber via a flange, a first buffer pad is arranged in the buffer chamber, and a third through hole for the hammer core to pass through is arranged in the middle of the flange and the first buffer pad.
[0016] The above technical solution is adopted: during use, the hammer handrail mechanism drives the hammer assembly to move close to the pile cap. When the first buffer pad is against the top of the pile cap, the chain and the hanger are removed to achieve normal piling function. At the same time, the setting of the first buffer pad can play a certain buffering effect when the hammer assembly is operating.
[0017] A further configuration of the utility model is: a replacement block is provided in the pile cap, the replacement block includes a truncated cone portion and a raised portion integrally formed with the truncated cone portion and located in the middle of the truncated cone portion, a fourth through hole is provided at the top end of the pile cap, the raised portion is located in the fourth through hole, a second buffer pad is provided between the inner wall of the top end of the pile cap and the truncated cone portion, and the second buffer pad is arranged around the raised portion.
[0018] The above technical solution is adopted: through the setting of the frustum, the protrusion and the fourth through hole, the hammer assembly moves downward, and when the first buffer pad abuts against the protrusion, the chain and the sling are removed at this time, and normal piling can be achieved. In addition, through the setting of the second buffer pad, during the piling process, it can play a buffering effect when the pile cap rebounds itself.
