Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a lifting device for a pile hammer. Background Art
[0002] The work of a pile hammer mainly involves using impact or vibration force to drive prefabricated wooden piles, steel piles or concrete piles into the ground to provide a solid foundation support for buildings or other structures. There are various types of pile hammers, and each type of pile hammer has its specific working principle and applicable scenarios. It is a machine specially used for the construction of prefabricated piles. It can complete the driving, sinking, pressing and pulling operations of piles.
[0003] The existing pile hammer has a landing gear connected to the hammer body through a hammer hanging wire rope in the crane, thereby driving the pile hammer to rise and fall. When the pile slips, if the landing gear and the hammer body are not separated quickly, the crane will be subjected to excessive tension, which will damage the pile frame and cause it to break.
[0004] At the same time, during the process of lifting cement piles, the steel wire rope in the pile lifting mechanism is spirally wound around the outer wall of the cement pile, and then fixed by hooks between the steel 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 steel 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; at the same time, when driving inverted piles, due to the lack of limiting the steel wire rope for pile lifting, the steel wire rope for pile lifting will enter the pile frame, causing wear on the pile frame and reducing the service life of the pile frame. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide a lifting device for a pile hammer capable of protecting a pile frame 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 solutions: a lifting device for a pile hammer, comprising an armrest seat installed with an external pile frame track and a landing gear installed on the armrest seat, the landing gear comprising a shell, a plurality of guide pulleys are arranged in the shell, and the characteristics are: hammer blocks connected with the pile hammer body are arranged on both sides of the shell, and a quick-release structure capable of facilitating the installation and separation of the landing gear and the pile hammer body is arranged between the hammer block and the shell; blocking rods are installed on both sides of the armrest seat near the landing gear, and the blocking rods can block the pile hanging wire rope on the side of the blocking rod away from the pile frame track.
[0007] The above technical scheme is adopted: compared with the prior art in which the pile hammer is easy to cause damage to the pile frame, the utility model adopts a quick-disassembly structure, which can facilitate the rapid installation and separation of the landing gear and the pile hammer body. When pile slippage occurs, it can react quickly to separate the landing gear from the pile hammer body, thereby preventing the winch from being subjected to excessive tension and effectively protecting the pile frame. At the same time, through the setting of the baffle rod, the upper end of the pile hanging wire rope can be blocked on the side of the baffle rod away from the pile frame track, so that when the pile hanging hook is unfastened, the baffle rod can buffer the impact force of the pile hanging wire rope retraction, offset some of the impact force, and reduce the damage of the pile hanging wire rope to the pile frame track. At the same time, when driving the pile, the baffle rod has a blocking effect on the pile hanging wire rope to prevent the pile hanging wire rope from entering the pile frame.
[0008] A further configuration of the utility model is: the quick-release structure includes a load-bearing block hinged to the shell and a rocker arm linked to the load-bearing block, an elastic member is provided between the rocker arm and the shell; a first movable groove is provided in the hammer block, which can be linked with the load-bearing block and cooperate with the load-bearing block to be able to be connected and separated with the hammer block; a second movable groove is provided on the shell for the hammer block to slide axially and be installed.
[0009] The above technical scheme is adopted: through the arrangement of the load-bearing block, the rocker arm, the elastic member and the first and second movable grooves, during use, the load-bearing block is linked with the hammer block, and the hammer block is installed on the matching pile hammer body. When the landing gear and the pile hammer body are in the installed state, the load-bearing block is located in the first movable groove and abuts against the groove top of the first movable groove, and the load-bearing block plays a load-bearing role at the same time; when the pile slips and needs to be separated, the landing gear is dropped by a crane. Since the bottom of the pile hammer body is located on the pile, the bottom of the hammer body has support. At this time, the landing gear can be moved downward relative to the pile hammer body by the crane, so that the load-bearing block abuts against the groove bottom of the first movable groove. At this time, the staff tightens the hemp rope pre-tied to the rocker arm to make the load-bearing block disengage from the second movable groove to complete the separation of the landing gear and the pile hammer body, thereby achieving the purpose of rapid separation of the landing gear and the pile hammer body.
[0010] A further configuration of the utility model is that an abutment block is provided at one end of the shell away from the rocker arm, the load-bearing block can be inserted into the first movable groove, and the top of the load-bearing block can abut against the top of the first movable groove, and the bottom can abut against the abutment block.
[0011] The above technical solution is adopted: when the landing gear is connected with the pile hammer body, the load-bearing block is passed through the first movable groove so that the top of the load-bearing block abuts against the first movable groove, and the bottom of the load-bearing block abuts against the abutting block. The landing gear lifts the pile hammer body, and the pile hammer body abuts against the load-bearing block through the first movable groove of the hammer lifting block. The bottom of the load-bearing block bears weight together through the abutting block. The hammer lifting block is connected to the pile hammer body, and one end of the load-bearing block abutting against the first movable groove is lifted. When it is lifted to a certain angle, the load-bearing block can be separated from the first movable groove, and the landing gear is separated from the pile hammer body.
[0012] A further arrangement of the utility model is: a first mounting hole is provided at the rocker arm near the load-bearing block, a sleeve rod is provided at the shell on the same side facing the rocker arm, one end of the elastic member is sleeved on the sleeve rod, and the other end is sleeved on the first mounting hole, and the shell is located above the rocker arm and is also provided with a first limit block for limiting the rotation angle of the rocker arm.
[0013] By adopting the above technical solution, the rocker arm is provided with an elastic member through the sleeve rod and the first mounting hole, thereby ensuring that the rocker arm can be reset after being pulled, and also providing a buffer when the rocker arm is reset, thereby reducing wear between structures and making the structure more durable.
[0014] A further configuration of the utility model is that a first installation groove for installing the pile hammer body is provided on the inner side of the hammer block.
[0015] By adopting the above technical solution, the first installation groove is provided to facilitate the installation of the hammer block and the pile hammer body, thereby improving the installation efficiency of the workers.
[0016] A further configuration of the utility model is that the baffle rod includes a mounting rod and an adjusting rod, the adjusting rod is slidably connected to one end of the mounting rod away from the armrest seat, the mounting rod is provided with a plurality of first adjusting holes, and the adjusting rod is provided with a plurality of second adjusting holes corresponding to the first adjusting holes.
[0017] 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.
[0018] A further configuration of the utility model is that a plurality of reinforcing ribs are arranged between the mounting rod and the end surface of the armrest seat, and a reinforcing rod is extended toward the mounting rod on the side of the armrest seat away from the landing gear.
[0019] The above technical solution is adopted: by setting the reinforcing ribs and the reinforcing rod, the firmness and stability of the guard bar installed on the armrest seat are further improved, making it more durable during use.
[0020] 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.
[0021] 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 external pile frame track, and at the same time, the armrest seat can be driven by the external crane to reciprocate along the external 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.

[0033] like Figure 1-5 The quick-release structure 4 shown includes a load-bearing block 41 hinged to the housing 21 and a rocker arm 42 linked to the load-bearing block 41. The load-bearing block 41 is provided with a first mounting groove 32 for mounting the pile hammer body 5 on the inner side. An elastic member 43 is provided between the rocker arm 42 and the housing 21. The rocker arm 42 is provided with a first mounting hole 421 near the load-bearing block 41. The housing 21 is provided with a sleeve rod 213 on the same side as the rocker arm 42. One end of the elastic member 43 is sleeved on the sleeve rod 213, and the other end is sleeved on the first mounting hole 421. Preferably, the elastic member 43 is a tension spring. The housing 21 is located above the rocker arm 42 and is further provided with a first limit block 214 for limiting the rotation angle of the rocker arm 42. Figure 3-4 The hammer block 3 shown is provided with a first movable groove 31 which can be linked with the load-bearing block 41 and cooperate with the load-bearing block 41 to engage, connect and separate with the hammer block 3. The housing 21 is provided with a second movable groove 211 for the hammer block 3 to slide axially and be installed.
[0034] like Figure 2-3The shell 21 shown has an abutment block 212 at one end away from the rocker arm 42 . The load-bearing block 41 can be inserted into the first movable groove 31 , and the top of the load-bearing block 41 can abut against the top of the first movable groove 31 , and the bottom of the load-bearing block 41 can abut against the abutment block 212 .
[0035] like Figure 1 , 2 The armrest seat 1 shown in 7 is provided with at least four clamps 14 spaced in sequence near one end of the pile frame track.

[0036] Compared with the pile hammer in the prior art which is easy to cause damage to the pile frame, the utility model adopts a quick-release structure 4. During use, the load-bearing block 41 is linked with the hammer block 3, and the hammer block 3 is installed on the pile hammer body 5. When the landing gear 2 and the pile hammer body 5 are in the installed state, the load-bearing block 41 is located in the first movable groove 31 and can abut against the top of the groove. At this time, the landing gear 2 can drive the pile hammer body 5 to rise and fall.

The rocker arm 42 is rotated to cause the load-bearing block 41 to fall off from the first movable groove 31, so as to achieve the purpose of quickly separating the landing gear 2 and the pile hammer body 5, so that in the case of pile slipping, they can be quickly separated to protect the pile frame; at the same time, through the setting of the blocking rod 11, the upper end of the pile hanging wire rope can be blocked on the side of the blocking rod 11 away from the pile frame track, so that when the pile hanging hook is unfastened, the blocking rod 11 can buffer the impact force of the retraction of the pile hanging wire rope, offset some of the impact force, and reduce the damage of the pile hanging wire rope to the pile frame track. At the same time, when driving the pile, the blocking rod has a blocking effect on the pile hanging wire rope to prevent the pile hanging wire rope from entering the pile frame.
[0037] Example 2: Figure 1 , 2 , 6, the structure of Example 2 is basically the same as that of Example 1, except that the blocking rod 11 includes a mounting rod 111 and an adjusting rod 112, the adjusting rod 112 is slidably connected to the end of the mounting rod 111 away from the armrest seat 1, the mounting rod 111 is provided with a plurality of first adjusting holes 111a, the adjusting rod 112 is provided with a plurality of second adjusting holes 112a corresponding to the first adjusting holes 111a, a plurality of reinforcing ribs 12 are provided between the mounting rod 111 and the end surface of the armrest seat 1, and a reinforcing rod 13 is extended toward the mounting rod 111 on the side of the armrest seat 1 away from the landing gear 2.
[0038] During use of the utility model, since there is a platform window on the top of the pile frame, when the blocking rod 11 is too long, the blocking rod 11 cannot pass through the platform window, and some longer piles cannot be driven. Therefore, the blocking rod 11 is retractable to achieve the ability to adjust the length of the blocking rod 11. The staff only needs to slide the adjusting rod 112 toward the inside of the mounting rod 111 in advance, and make the first and second adjusting holes 112a correspond to each other, and connect them through the first and second adjusting holes 112a with fasteners, so that the length of the blocking rod 11 can be adjusted, so that the blocking rod 11 can pass through the platform window, thereby improving its versatility. In addition, when the adjusting rod 112 is broken or worn during long-term use, the structure is also convenient for replacement.
[0039] The above examples are only two preferred specific examples of the present invention. Common changes and substitutions made by those skilled in the art within the technical solution of the present invention are all included in the protection scope of the present invention.
