Technical Field
[0001] This application relates to the technical field of pile driving hammer construction equipment, and specifically to a cable reel device for excavator pile driving hammers. Background Technology
[0002] During operation, excavator pile hammers require cables to provide power, and the proper management of cable winding and unwinding is crucial for smooth construction. Currently, cable winding and unwinding for excavator pile hammers typically utilizes cable reeling equipment. However, this equipment lacks control over cable arrangement and compaction, easily leading to uneven cable arrangement on the reel, excessive localized stress, and consequently, cable sheath wear, twisting, or even breakage. This poses a risk of electrical leakage and seriously compromises construction safety. Summary of the Invention
[0003] In view of this, this application provides a cable reel device for excavator pile hammers to solve the problem that the lack of control over cable arrangement and compaction in reel equipment can easily lead to uneven cable arrangement on the reel, excessive local stress, and consequently, wear, twisting, or even breakage of the cable sheath, posing a risk of leakage and seriously affecting construction safety.
[0004] In a first aspect, this application discloses a cable reel device for an excavator pile hammer, comprising: seat body; A cable winding assembly includes a first drive member and a cable reel. The first drive member is mounted on the base and connected to the cable reel. The first drive member is capable of driving the cable reel to rotate. The cycloidal assembly includes a second driving member and a clamping member. The second driving member is disposed on the base and connected to the clamping member. The second driving member can drive the clamping member to move along the axial direction of the coil. The clamping member is used to clamp the cable.
[0005] The clamping assembly includes a first bracket, a first elastic element, and a pressure roller. The first bracket is hinged to the base body. The first elastic element is connected to both the first bracket and the base body. The pressure roller is rotatably connected to the first bracket. The first elastic element has an initial elastic force, which results in a compacted state where the outer wall of the pressure roller abuts against the cable wound on the spool.
[0006] Beneficial effects: The base provides the installation foundation for the entire device. The first drive component rotates the reel, realizing the winding and unwinding of the cable, meeting the cable length adjustment requirements during excavator pile driving. After the clamping component holds the cable, it can drive the cable to move along the axial direction of the reel during winding, avoiding the cable being concentrated in one position during winding, making the cable neatly arranged on the reel, reducing the situation of excessive local stress on the cable, thereby reducing the risk of cable sheath wear, twisting, and breakage, reducing the risk of leakage, and improving the safety of construction site. The initial elastic force of the first elastic component causes the pressure roller to abut against the cable wound on the reel, which can compact the cable during the winding process, avoid gaps between cable layers, ensure winding quality, and prevent the cable wound on the reel from being loose.
[0007] In one alternative implementation, the winding assembly further includes: A speed reducer is fixedly connected to the base body, the first driving component is a first motor, and the speed reducer is drivenly connected to the first motor; The coupling has one end connected to the reducer for transmission and the other end fixedly connected to the rotating shaft of the coil.
[0008] Beneficial effects: The reducer is connected to the first motor, which can reduce the output speed of the first motor and increase the output torque. The coupling connects the reducer and the rotating shaft of the cable reel, which not only realizes the transmission of power, but also reduces the vibration and impact during the power transmission process, avoids the instability of the cable reel rotation caused by vibration, and thus prevents the cable winding from deviating and becoming disordered. At the same time, it can also protect the first motor and the reducer, extend the service life of the entire winding assembly, and ensure the long-term stable operation of the device.
[0009] In one alternative implementation, the second driving element includes: The second motor is fixedly connected to the base body; A support frame having a first groove provided thereon; The first lead screw is located in the first groove. One end of the first lead screw is rotatably connected to the inner wall of the first groove, and the other end extends out of the first groove and is connected to the second motor for transmission. The first slider is slidably connected to the support frame, and the first slider is sleeved on the outer periphery of the first lead screw and threadedly connected to the first lead screw. The clamping member is fixed on the first slider.
[0010] Beneficial effects: The second motor provides power for the movement of the clamping component. The first groove on the support frame provides installation space for the first lead screw. The first lead screw is connected to the second motor for transmission. When the first lead screw rotates, it can drive the first slider sleeved on its outer periphery to move. Since the first slider is threadedly connected to the first lead screw, the movement distance of the first slider can be precisely controlled, thereby driving the clamping component to move precisely. This allows the cable to be evenly wound on the reel at a preset interval, further improving the neatness of the cable arrangement, reducing local stress on the cable, and protecting the cable.
[0011] In one alternative embodiment, the clamping member includes: The first pulley is rotatably connected to the first slider; The second pulley is spaced apart from the first pulley and is rotatably connected to the first slider; The cable is clamped between the first pulley and the second pulley.
[0012] Beneficial effects: A clamping space is formed between the first and second pulleys, which is used to clamp the cable. That is, both sides of the cable abut against the first and second pulleys respectively. During the winding and unwinding process, the cable drives the first and second pulleys to rotate under the action of friction. The first and second pulleys can limit the cable and prevent the cable from deviating or shaking during the winding and unwinding process. This ensures that the cable can be stably wound on the reel, further improves the neatness of winding, reduces uneven stress on the cable, and extends the service life of the cable.
[0013] In one alternative embodiment, the cycloidal assembly further includes a dust cover fixedly connected to the base and located directly above the first lead screw.
[0014] Beneficial effects: The dust cover reduces dust, sand, rainwater, oil, or other debris falling on the lead screw, preventing dust and sand accumulation from affecting the threaded transmission between the lead screw and the slider, and preventing jamming or seizing. At the same time, the dust cover also reduces the corrosion of the lead screw caused by rainwater and oil, reducing wear and rust, and extending the lead screw's service life.
[0015] In one alternative implementation, it further includes: The coil includes a cylindrical body, a rotating shaft, and a first baffle and a second baffle arranged opposite to each other. The cylindrical body is sleeved on the outer periphery of the rotating shaft and is fixedly connected to the outer wall of the rotating shaft. The first baffle and the second baffle are respectively fixedly connected to the two ends of the cylindrical body, and the first baffle has through holes. The second bracket is fixedly connected to the first baffle. A limiting plate is fixedly connected to the second bracket, and the free end of the limiting plate extends through the through hole into the gap between the first baffle and the second baffle; The first rod is fixedly connected to the second bracket; The first nut is threadedly connected to the first rod body and abuts against the limiting plate; The rotation of the first nut changes the gap between the limiting plate and the outer wall of the cylinder, and the gap between the limiting plate and the outer wall of the cylinder is used to insert a cable head.
[0016] Beneficial effects: The reel's cylinder is used for winding cables. The first and second baffles are respectively located at both ends of the cylinder, which limit the cable wound on the cylinder, preventing it from falling off the reel during winding and unwinding, ensuring the stability of the cable winding. The through-hole on the first baffle provides a passage for the limiting plate, which extends between the first and second baffles, forming a gap with the outer wall of the cylinder for inserting the cable head. This facilitates the fixing of the cable head, preventing loosening or falling off during the initial winding stage, and ensuring smooth cable winding. By rotating the first nut, the gap between the limiting plate and the outer wall of the cylinder can be changed, accommodating cable heads of different diameters, improving the device's versatility. It also allows adjustment of the clamping force on the cable head as needed, ensuring a secure fixation and further guaranteeing the stability of cable winding.
[0017] In one alternative implementation, a buffer component is also included, comprising: A first support plate is disposed on the base body; The second elastic element is embedded in the first bearing plate, and the second elastic element has a first through hole; The cable passes through the first through hole and enters the clamping member.
[0018] Beneficial effects: The first support plate provides a mounting carrier for the second elastic element. The first through hole on the second elastic element allows the cable to pass through, guiding the cable and preventing it from shifting or twisting before entering the clamping device. This ensures the cable can smoothly enter the clamping device and guarantees the smoothness of the winding operation. Simultaneously, the second elastic element is elastic; when the cable is subjected to slight pulling or shaking, the second elastic element can undergo elastic deformation, acting as a buffer to reduce the impact of tensile force on the cable. This prevents damage to the cable due to excessive instantaneous force, further protecting the cable, extending its service life, and reducing the risk of leakage.
[0019] In one optional implementation, the buffer component further includes: The first frame has a hollow cavity, and the inner wall of the hollow cavity is provided with a plurality of second grooves; Multiple second rods are distributed at intervals along the circumference of the first bearing plate. Each second rod is fixedly connected to the first bearing plate and is inserted into the corresponding second groove. Multiple first springs are provided, each of which is sleeved on the outer periphery of the corresponding second rod, and both ends of each first spring are fixedly connected to the inner wall of the hollow cavity and the first support plate.
[0020] Beneficial effects: The hollow cavity of the first frame provides installation space for the first bearing plate, the second rods, and the first spring. Multiple second rods are spaced apart circumferentially along the first bearing plate and inserted into the second grooves of the first frame, providing limiting and guiding functions for the first bearing plate. The two ends of the first spring on the outer periphery of each second rod are fixedly connected to the inner wall of the hollow cavity and the first bearing plate, respectively. When vibrations occur during excavator operation, or when the cable is stretched, the first spring can undergo elastic deformation, acting as a buffer and shock absorber, reducing the impact of vibration and tensile forces on the cable and preventing cable damage. Simultaneously, the multiple springs ensure a more uniform buffering effect, further enhancing cable protection and ensuring stable operation of the device in complex construction site environments.
[0021] In one alternative implementation, a rollback prevention component is also included, comprising: The third bracket is fixedly connected to the base body; The second slider is slidably connected to the third bracket; The third slider is spaced apart from the second slider and is slidably connected to the third bracket; The second spring has its two ends fixedly connected to the third bracket and the second slider, respectively. The third spring has its two ends fixedly connected to the third bracket and the third slider, respectively. The third pulley is rotatably connected to the second slider; The fourth pulley is rotatably connected to the third slider; The third pulley and the fourth pulley are located on both sides of the cable, and the second spring and the third spring have the function of driving the third pulley and the fourth pulley to move closer to each other.
[0022] Beneficial effects: The third bracket provides a mounting base for the second and third sliders, springs, and pulleys. Both the second and third sliders are slidably connected to the third bracket. The elastic force of the second and third springs drives the third and fourth pulleys closer together, clamping and limiting the cable located between them, preventing deviation and swaying during winding and unwinding, and ensuring stable cable transmission. Simultaneously, when the cable is subjected to instantaneous tension or a slight change in diameter, the second and third springs can undergo elastic deformation, acting as a buffer to reduce the impact of tensile force on the cable and prevent damage. The third and fourth pulleys roll in contact with the cable, reducing friction and further protecting the cable sheath, extending the cable's service life.
[0023] In one optional implementation, the anti-rollback component further includes: The first ratchet is fixedly connected to the pin of the third pulley; The first pawl is hinged to the second slider, and the first pawl abuts against one of the teeth of the first ratchet. The fourth spring has its two ends fixedly connected to the first pawl and the second slider, respectively; The second ratchet is fixedly connected to the pin of the fourth pulley; The second pawl is hinged to the third slider, and the second pawl abuts against one of the teeth of the second ratchet. The fifth spring has its two ends fixedly connected to the second pawl and the third slider, respectively.
[0024] Beneficial effects: The first ratchet is fixedly connected to the third pulley via a pin; the first pawl is hinged to the second slider and abuts against the teeth of the first ratchet; the fourth spring provides elasticity to the first pawl, ensuring it always abuts against the first ratchet and preventing the third pulley from rotating in the opposite direction. Similarly, the second ratchet is fixedly connected to the fourth pulley via a pin; the second pawl is hinged to the third slider and abuts against the teeth of the second ratchet; the fifth spring provides elasticity to the second pawl, preventing the fourth pulley from rotating in the opposite direction. This provides unidirectional limiting for the cable, preventing it from loosening or retracting after winding, ensuring the cable remains stably on the reel, preventing cable loosening that could lead to disordered arrangement and uneven stress, further protecting the cable. It also prevents cable retraction from interfering with the normal operation of the excavator's pile hammer, improving construction safety and stability. Attached Figure Description

[0033] The cable reel device for excavator pile hammers provided in this application embodiment, such as Figures 1 to 7As shown, the assembly includes a base 101, a winding assembly, a cycloidal assembly, and a clamping assembly. The winding assembly includes a first drive member 201 and a coil 501. The first drive member 201 is mounted on the base 101 and connected to the coil 501, and can drive the coil 501 to rotate. The cycloidal assembly includes a second drive member and a clamping member 302. The second drive member is disposed on the base 101 and connected to the clamping member 302. The second drive member can drive the clamping member 302 to move along the axial direction of the coil 501, and the clamping member 302 is used to clamp the cable. The clamping assembly includes a first bracket 401, a first elastic element 402, and a pressure roller 403. The first bracket 401 is hinged to the base 101. The first elastic element 402 is connected to both the first bracket 401 and the base 101. The pressure roller 403 is rotatably connected to the first bracket 401. The first elastic element 402 has an initial elastic force, which compresses the outer wall of the pressure roller 403 against the cable wound on the reel 501. The base 101 provides the installation foundation for the entire device. The first driving element 201 drives the reel 501 to rotate, realizing the winding and unwinding of the cable, meeting the cable length adjustment requirements during excavator pile driving. After clamping the cable, the clamping element 302 can drive the cable to move axially along the reel 501 during winding, avoiding the cable being concentrated in one position during winding, making the cable neatly arranged on the reel, reducing the situation of excessive local stress on the cable, thereby reducing the risk of cable sheath wear, twisting, and breakage, reducing the risk of leakage, and improving the safety of construction site work. The initial elastic force of the first elastic element 402 causes the pressure roller 403 to come into contact with the cable wound on the reel 501, which can compact the cable during the winding process, prevent gaps between cable layers, ensure winding quality, and prevent the cable wound on the reel 501 from becoming loose.
[0034] In this embodiment, as Figure 1 and Figure 2 As shown, the base 101 is a frame structure, providing a mounting base for the components on it. The base 101 is fixed to the cable laying cart by bolts. The cable laying cart includes a chassis, wheels, and a drive mechanism. The wheels are mounted on the chassis. The drive mechanism may include an electric motor and an internal combustion engine, and is used to drive the cart to move. The first drive member 201 may be an electric motor, a hydraulic motor, or other mechanisms that perform circular motion. The second drive member may be a lead screw mechanism, a linear motor, a crank-slider mechanism, or other mechanisms that move in a straight line. The first elastic member 402 may be made of rubber, spring steel, copper alloy, or other elastic materials. The clamping member 302 may be a support with a through hole, or the clamping member 302 may be a first clamp and a second clamp arranged opposite each other, or it may be a first pulley 3021 and a second pulley 3022 arranged opposite each other.
[0035] In this embodiment, as Figure 3As shown, the cable winding assembly also includes a reducer 202 and a coupling 203. The first drive component 201 is preferably a first motor, mounted on the base 101, providing power for the rotation of the cable reel 501. The cable reel 501 includes a cylindrical body, a rotating shaft, and opposing first and second baffles. The cylindrical body is fitted around the outer circumference of the rotating shaft and fixedly connected to the outer wall of the rotating shaft. The first and second baffles are respectively fixedly connected to both ends of the cylindrical body. Multiple through holes are provided on both the first and second baffles to reduce their weight, thereby reducing the overall weight of the cable reel 501. The first and second baffles prevent the cable from falling off from both ends of the cable reel 501 during winding and unwinding, ensuring stable cable winding. The reducer 202 is fixedly connected to the base 101 and connected to the output shaft of the first motor via the coupling 203. The reducer 202 reduces the output speed of the first motor and increases the output torque, making the rotation of the cable reel 501 smoother. Preferably, the reducer 202 is a planetary reducer 202. One end of the coupling 203 is fixedly connected to the output shaft of the reducer 202, and the other end is fixedly connected to the rotating shaft of the coil 501. The coupling 203 is a flexible coupling. The coupling 203 connects the reducer 202 and the rotating shaft of the coil 501, which not only realizes the transmission of power, but also reduces the vibration and impact during the power transmission process, avoids the coil 501 from rotating unstablely due to vibration, and thus prevents the cable winding from deviating and arranging disorderly. At the same time, it can also protect the first motor and the reducer 202, extend the service life of the entire winding assembly, and ensure the long-term stable operation of the device.
[0036] In this embodiment, as Figure 1 As shown, the cycloidal assembly also includes a dust cover 303. (As...) Figure 3 and Figure 6As shown, the second driving component includes a second motor 3011, a support frame 3012, a first lead screw 3013, and a first slider 3014. The second motor 3011 is fixedly connected to the base 101, which can be fixed by bolts or welding. The second motor 3011 provides power for the movement of the clamping member 302. The support frame 3012 is welded and fixed to the base 101. The support frame 3012 is located below the coil 501. A first groove is provided on the support frame 3012 to provide installation space for the first lead screw 3013. The first lead screw 3013 is located in the first groove, with one end rotatably connected to the inner wall of the first groove and the other end extending out of the first groove and being driven by the second motor 3011. The first slider 3014 is slidably connected to the support frame 3012, sleeved on the outer circumference of the first lead screw 3013, and threadedly connected to the first lead screw 3013. The clamping member 302 is fixed on the first slider 3014. When the second motor 3011 drives the first lead screw 3013 to rotate, the first slider 3014 moves along the first lead screw 3013, thereby driving the clamping member 302 to move, thus achieving precise control over the moving distance of the clamping member 302. The clamping member 302 includes a first pulley 3021 and a second pulley 3022. Both the first pulley 3021 and the second pulley 3022 are rotatably connected to the first slider 3014 and are spaced apart, forming a clamping space for clamping the cable. Specifically, both sides of the cable abut against the first pulley 3021 and the second pulley 3022 respectively. During winding and unwinding, the cable, under the action of friction, drives the first pulley 3021 and the second pulley 3022 to rotate, which limits the cable and prevents it from shifting or shaking. Figure 3 As shown, the dust cover 303 is fixedly connected to the base 101 and located directly above the lead screw. It reduces dust, sand, rainwater, oil, or other debris falling on the lead screw, preventing interference with the threaded transmission between the lead screw and the slider, and reducing wear and corrosion of the lead screw. The cycloidal assembly drives the lead screw to rotate via the second motor 3011, which in turn moves the clamping member 302, causing the cable to be evenly wound onto the reel 501 at a preset interval, improving the neatness of the cable arrangement.
[0037] In this embodiment, as Figure 2As shown, the first support 401 is also a frame structure. The first support 401 is hinged to the base 101 via a pin. The first elastic element 402 is a spring, which is connected to both the first support 401 and the base 101. The two ends of the first elastic element 402 are hooked onto the first support 401 and the base 101, respectively. There are two first elastic elements 402, which are spaced apart and located inside the base 101. The pressure roller 403 is rotatably connected to the first support 401. Under the elastic force of the first elastic element 402, the first support 401 rotates towards the coil 501, thereby causing the outer wall of the pressure roller 403 to come into contact with the cable wound on the coil 501, compacting the cable during the winding process, preventing gaps between cable layers, and ensuring winding quality.
[0038] In this embodiment, as Figure 7 As shown, it also includes a second bracket 502, a limiting plate 503, a first rod 504, and a first nut 505. The second bracket 502 is fixedly connected to the first baffle. The second bracket 502 is flat and made of metal. The limiting plate 503 is a C-shaped plate. One end of the limiting plate 503 is fixedly connected to the second bracket 502. The free end of the limiting plate 503 extends through a through hole into the gap between the first baffle and the second baffle. The through hole on the first baffle provides a passage for the limiting plate 503. One end of the first rod 504 passes through the limiting plate 503 and is fixedly connected to the second bracket 502. The first nut 505 is threadedly connected to the first rod 504 extending out of the limiting plate 503, and the first nut 505 abuts against the limiting plate 503. By rotating the first nut 505, the limiting plate 503 is deformed, thereby changing the gap between the limiting plate 503 and the outer wall of the cylinder. This gap is used to insert the cable head. The gap between the limiting plate 503 and the outer wall of the cylinder facilitates the insertion of the cable head, preventing it from loosening or falling off during the initial winding stage, and ensuring smooth initiation of the cable winding operation. By rotating the first nut 505, the gap between the limiting plate 503 and the outer wall of the cylinder can be changed, accommodating cable heads of different diameters, improving the versatility of the device. At the same time, the clamping force on the cable head can be adjusted as needed to ensure a firm fixation of the cable head, further guaranteeing the stability of the cable winding. In this embodiment, as Figure 1 and Figure 4As shown, it also includes a buffer assembly, which comprises a first support plate 601, a second elastic element 602, a first frame 603, multiple second rods 605, and multiple first springs 606. The first support plate 601 is disposed on the base 101 and provides a mounting carrier for the second elastic element 602. The second elastic element 602 is embedded in the first support plate 601 and has a first through hole. The second elastic element 602 is made of rubber, and the cable enters the clamping member 302 after passing through the first through hole. The first through hole on the second elastic element 602 allows the cable to pass through and guides the cable, preventing it from shifting or twisting before entering the clamping member 302, ensuring that the cable can smoothly enter the clamping member 302 and guaranteeing the smoothness of the winding operation. Meanwhile, the second elastic element 602 is elastic. When the cable is slightly pulled or shaken, the second elastic element 602 can undergo elastic deformation, playing a buffering role, reducing the impact of pulling force on the cable, preventing the cable from being damaged due to excessive instantaneous force, further protecting the cable, extending the cable's service life, and reducing the risk of leakage. The first frame 603 has a hollow cavity, which provides installation space for the first bearing plate 601, the second rod 605, and the first spring 606. The first frame 603 consists of two clamping plates, one of which is welded and fixed to the base 101, and the other clamping plate is fixedly connected to the clamping plate by bolts. The hollow cavity is a rectangular hollow cavity, and multiple second grooves 604 are formed on the inner wall of the hollow cavity. Multiple second rods 605 are distributed circumferentially around the first bearing plate 601. Each second rod 605 is fixedly connected to the first bearing plate 601 and inserted into the corresponding second groove 604, which plays a limiting and guiding role for the first bearing plate 601. Each second rod 605 is fitted with a first spring 606 around its outer periphery. The two ends of the spring are fixedly connected to the inner wall of the hollow cavity and the first bearing plate 601, respectively. When the excavator vibrates during operation or the cable is stretched, the first spring 606 can undergo elastic deformation, acting as a buffer and shock absorber to reduce the impact of vibration and tension on the cable and prevent cable damage. Simultaneously, the multiple springs ensure a more uniform buffering effect, further enhancing the protection of the cable and ensuring stable operation of the device in complex construction site environments.
[0039] In this embodiment, as Figure 3 and Figure 5As shown, it also includes a third bracket 701, a second slider 702, a third slider 703, a second spring 704, a third spring 705, a third pulley 706, a fourth pulley 707, a first ratchet 708, a first pawl 709, a fourth spring, a second ratchet 710, a second pawl 711, and a fifth spring. The third bracket 701 is fixedly connected to the base 101 by welding. The second slider 702 and the third slider 703 are both slidably connected to the third bracket 701. Two sliding grooves are opened on both sides of the third bracket 701, and the second slider 702 and the third slider 703 are slidably connected to the two sliding grooves respectively. The two ends of the second spring 704 are fixedly connected to the third bracket 701 and the second slider 702 respectively, and the two ends of the third spring 705 are fixedly connected to the third bracket 701 and the third slider 703 respectively by hooks. The third pulley 706 is rotatably connected to the second slider 702, and the fourth pulley 707 is rotatably connected to the third slider 703. The third pulley 706 and the fourth pulley 707 are located on opposite sides of the cable. The elastic force of the second spring 704 and the third spring 705 causes them to move closer together, clamping and limiting the cable. When the cable is subjected to instantaneous tension or a slight change in diameter, the springs can undergo elastic deformation to provide a buffering effect. The first ratchet 708 is fixedly connected to the pin of the third pulley 706. The first pawl 709 is hinged to the second slider 702 and abuts against one tooth of the first ratchet 708. The two ends of the fourth spring are fixedly connected to the first pawl 709 and the second slider 702, respectively. Similarly, the second ratchet 710 is fixedly connected to the pin of the fourth pulley 707. The second pawl 711 is hinged to the third slider 703 and abuts against one tooth of the second ratchet 710. The two ends of the fifth spring are fixedly connected to the second pawl 711 and the third slider 703, respectively. It can provide unidirectional limiting for the cable, preventing it from loosening or retracting after winding. This ensures the cable remains stably on the reel after winding, preventing it from becoming loose and causing disorder or uneven stress, thus further protecting the cable. It also prevents the cable from retracting and affecting the normal operation of the excavator's pile hammer, improving the safety and stability of the construction.
