Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and in particular to a forced heat dissipation and lubrication device, a vibrating gear box and a vibrating pile hammer. Background Art

[0002] Vibratory pile hammers are widely used on construction sites, primarily for driving piles for buildings. The vibratory gearbox is a key component of the vibratory pile hammer. During operation, the motor drives the main eccentric shaft assembly to rotate at high speed, which in turn drives the secondary eccentric shaft assembly via the gears on this main eccentric shaft assembly. The main and secondary eccentric shaft assemblies are symmetrically arranged, so that the horizontal components of their centrifugal forces cancel each other out and the vertical components are superimposed, forming an exciting force. This drives the gearbox, jaws, and pile body to generate high-frequency vibrations, which in turn causes vibrational liquefaction between the pile body and the soil, reducing friction between the pile body and the soil and improving the efficiency of pile driving and extraction.

[0003] When the vibration gearbox is working, the main eccentric shaft assembly and the auxiliary eccentric shaft assembly rotate at high speed under the support of the bearings. A large amount of heat is generated inside the bearings due to dynamic friction. At the same time, the gears in the main eccentric shaft assembly and the auxiliary eccentric shaft assembly stir the lubricating oil during the high-speed rotation. The lubricating oil lubricates the bearings and the gear meshing surfaces by splashing inside the vibration gearbox. However, the lubricating oil in the current vibration gearbox cannot flow and dissipate heat reliably, resulting in excessively high lubricating oil temperature, which in turn causes excessively high bearing temperature, easy deformation of the bearings, and even bearing jamming. The lubricating properties of the lubricating oil deteriorate under high temperature environment, resulting in poor lubrication of the gear meshing surfaces and bearings, easy damage to the bearings, and easy pitting corrosion on the gear surfaces, thereby reducing the service life of the vibration gearbox and a high failure rate.

[0004] Therefore, there is an urgent need for a forced heat dissipation and lubrication device, a vibrating gear box and a vibrating pile hammer to solve the above technical problems. Summary of the Invention

[0021] The driving pump is arranged at an end of the main transmission shaft or the auxiliary transmission shaft.

[0022] As a preferred technical solution of the above-mentioned vibration gearbox, the drive pump is arranged at the end of the auxiliary transmission shaft, the box body is embedded with a first bearing, one end of the auxiliary transmission shaft is connected to the drive pump through the first bearing, and the first bearing is provided with a first bearing end cover on the side facing the drive pump. The bearing pressure plate of the first bearing end cover is provided with a first lubricating oil hole for lubricating oil to enter, and the return oil pipe is connected to the first lubricating oil hole.

[0025] The present invention also provides a vibratory pile hammer, comprising the above-mentioned vibratory gearbox.

[0026] Beneficial effects of the present invention:

[0027] 1. The forced heat dissipation lubrication device provided by the present invention is arranged in a vibrating gearbox, and includes a driving pump, an oil suction structure, a cooling structure and an oil return pipe, wherein the driving pump is arranged in the vibrating gearbox; the oil suction structure is connected to the oil inlet of the driving pump, so as to suck the lubricating oil at the bottom of the vibrating gearbox into the driving pump; the inlet of the cooling structure is connected to the oil outlet of the driving pump, so as to cool the lubricating oil; one end of the oil return pipe is connected to the outlet of the cooling structure, and the other end of the oil return pipe transports the lubricating oil into the vibrating gearbox. The setting of the cooling structure can achieve the purpose of cooling the high-temperature lubricating oil, thereby reducing the oil temperature of the lubricating oil in the vibrating gearbox and preventing the bearing from being deformed and stuck due to excessive temperature. Due to the reduction in the lubricating oil temperature, the lubricating properties of the lubricating oil remain stable, and the lubricating oil returned to the vibrating gearbox through the oil return pipe acts on the bearings and gears, so that the bearings and gears can be well lubricated, and the damage rate of the bearings and the pitting rate of the gears are reduced.

[0028] 2. The first shock absorber can effectively isolate vibration, reduce the impact of high-frequency vibration on the cooling structure, and improve the reliability of the cooling structure.

[0029] 3. The main distributor and the slave distributor can redistribute the cooled lubricating oil to the bearings and gear meshing of the vibration gearbox, thereby forcibly cooling and lubricating the bearings and gears, ensuring sufficient and reliable lubrication of the bearings and gears and improving reliability.

[0030] 4. The vibration gearbox provided by the present invention can reduce the temperature of the lubricating oil by cooling it through the cooling structure. Therefore, it can act on the bearings and gears to ensure that the bearings and gears are well lubricated, preventing the bearings from getting stuck due to high temperatures, thereby increasing the service life of the vibration gearbox.

[0031] 5. The power of the driving pump directly adopts the power of the driven eccentric shaft, and there is no need to set up other power structures for the driving pump, which can reduce the space occupied by the forced heat dissipation and lubrication device and reduce the manufacturing and use costs.

[0032] 6. The vibration gearbox vibrates at a high frequency under the action of the main transmission shaft and the auxiliary transmission shaft, and stirs the lubricating oil inside it to form oil mist. The lubricating oil mist falls on the bearing seat, and the lubricating oil accumulates in the oil storage tank and flows to the bearing through the second lubricating oil hole to lubricate the bearing.

[0033] 7. The lubricating oil sprayed onto the bearing through the first lubricating oil hole in the bearing pressure plate lubricates the bearing, accumulates between the bearing pressure plate and the bearing seat, and then falls back to the bottom of the vibration gearbox through the oil outlet hole in the bearing seat. The lubricating oil sprayed onto the gear meshing area naturally scatters to the bottom of the vibration gearbox; the lubricating oil at the bottom of the vibration gearbox is drawn out by the oil suction structure and enters the cooling structure. The cooled lubricating oil returns to the vibration gearbox through the oil return pipe, achieving the purpose of lubricating oil circulation and cooling.

[0034] 8. The vibratory pile hammer provided by the present invention has a longer service life and a lower maintenance rate because the lubricating oil in the vibratory gearbox can be cooled. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0056] In the description of this embodiment, the terms "upper," "lower," "right," and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely for ease of description and simplified operation. They do not indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meanings.

[0057] During the operation of the vibratory pile hammer in the prior art, the temperature of the lubricating oil increases, which in turn causes the temperature of the bearing to increase, resulting in deformation and seizure of the bearing. The increase in the temperature of the lubricating oil and the deterioration of the lubrication properties will cause damage to the bearing and pitting on the gear surface, resulting in a shortened service life of the vibratory gearbox and an increased failure rate.

[0058] In order to solve the above problems, this embodiment provides a vibratory pile hammer, which can cool the lubricating oil during operation, thereby suppressing the deterioration of the lubricating oil properties, preventing bearings from getting stuck and being damaged, and reducing the failure rate of the vibratory gearbox.

[0059] The vibratory pile hammer includes a vibratory gear box, and the lubricating oil in the vibratory gear box can be cooled in the working state, thereby increasing the service life of the vibratory gear box. Figure 1 and Figure 2 As shown, the vibration gearbox includes a box body 7, a transmission structure 8 and a forced heat dissipation and lubrication device. Figure 2 and Figure 6As shown, the transmission device includes a power mechanism 85, a main transmission shaft and a secondary transmission shaft, the power mechanism 85 is connected to the main transmission shaft, the main transmission shaft is connected to the secondary transmission shaft, the main transmission shaft and the secondary transmission shaft are arranged in the box body 7, and the power mechanism 85 is arranged outside the box body 7; preferably, the main transmission shaft includes a main eccentric shaft 81 and a first gear 82, the first gear 82 is arranged on the main eccentric shaft 81, and the first gear 82 and the main eccentric shaft 81 are connected by a key; the secondary transmission shaft includes a driven eccentric shaft 83 and a second gear 84, the second gear 84 is arranged on the driven eccentric shaft 83, the second gear 84 is connected to the driven eccentric shaft 83 by a key, and the first gear 82 and the second gear 84 are engaged, so that the main eccentric shaft 81 and the driven eccentric shaft 83 rotate simultaneously.

[0060] The power mechanism 85 in this embodiment is a vibration motor, the output end of the vibration motor is connected to the main eccentric shaft 81 through a coupling, and the vibration motor drives the main eccentric shaft 81 to rotate. Since the main eccentric shaft 81 and the driven eccentric shaft 83 are connected by the first gear 82 and the second gear 84, the driven eccentric shaft 83 rotates together with the main eccentric shaft 81.

[0061] Bearings are provided at both ends of the main eccentric shaft 81 and the driven eccentric shaft 83 to respectively support the main eccentric shaft 81 and the driven eccentric shaft 83. The provision of the bearings can reduce the friction coefficient of the main eccentric shaft 81 and the driven eccentric shaft 83 during movement and ensure the rotational accuracy of the main eccentric shaft 81 and the driven eccentric shaft 83. Because the vibratory pile hammer is a construction machine, in this embodiment, bearing end caps are also provided on the outside of the bearings to prevent dust, stones and sand from entering the bearings in harsh environments.

[0062] Optionally, in this embodiment, the forced heat dissipation lubrication device is provided on the vibration gear box, such as Figure 2-6 As shown, the forced heat dissipation lubrication device comprises a drive pump 1, an oil suction structure 2, a cooling structure 3, and an oil return pipe 4. The drive pump 1 is mounted within the housing 7 of the vibrating gearbox. The oil suction structure 2 is connected to the oil inlet of the drive pump 1 to draw lubricating oil from the bottom of the vibrating gearbox into the drive pump 1. The inlet of the cooling structure 3 is connected to the oil outlet of the drive pump 1 to cool the lubricating oil. One end of the oil return pipe 4 is connected to the outlet of the cooling structure 3, and the other end of the oil return pipe 4 delivers the lubricating oil to the vibrating gearbox. In other words, the cooling structure 3 cools the high-temperature lubricating oil at the bottom of the housing 7 and then returns it to the vibrating gearbox to lubricate the bearings and gears therein. The provision of the cooling structure 3 cools the high-temperature lubricating oil, thereby reducing the oil temperature within the vibrating gearbox and preventing bearings from overheating and causing deformation and seizure. Due to the reduced oil temperature, the lubricating properties of the lubricating oil remain stable, ensuring good lubrication of both the bearings and gears. This reduces the bearing damage rate and the pitting corrosion rate of the gears, thereby extending the service life of the vibrating gearbox.

[0063] Optionally, the drive pump 1 is arranged at the end of the main transmission shaft or the auxiliary transmission shaft. Preferably, in this embodiment, the drive pump 1 is arranged at the end of the auxiliary transmission shaft, that is, the drive pump 1 is arranged at the end of the driven eccentric shaft 83. The main eccentric shaft 81 drives the driven eccentric shaft 83 to rotate, and the driven eccentric shaft 83 drives the drive pump 1 to work, so as to suck the lubricating oil at the bottom of the box body 7 into the cooling structure 3. The power of the drive pump 1 directly adopts the power of the driven eccentric shaft 83, and there is no need to set up other power structures for the drive pump 1. It can reduce the space occupied by the forced heat dissipation lubrication device and reduce the manufacturing and use costs.

[0064] Preferably, in this embodiment, Figure 2 and Figure 6 As shown, the cooling structure 3 includes a radiator, which is arranged on the vibration gearbox. The radiator is an air-cooled radiator, and its specific structure is a prior art and will not be repeated here. Furthermore, in this embodiment, the vibration gearbox also includes a gearbox support frame 71, wherein the gearbox support frame 71 is arranged on the outside of the box body 7, and the gearbox support frame 71 is fixedly arranged on the box body 7 to install the box body 7 on other structures of the vibration pile hammer. The cooling structure 3 is arranged on the gearbox support frame 71 to achieve cooling of the lubricating oil at the bottom of the box body 7. The driving pump 1 sucks the lubricating oil from the bottom of the vibration gearbox through the oil suction structure 2, and the lubricating oil enters the radiator through the driving pump 1, and uses natural wind to dissipate heat from the lubricating oil to reduce the temperature of the lubricating oil.

[0065] Since the vibrating gearbox will generate large vibrations during operation, frequent vibrations will cause the connection between the cooling structure 3 and the gearbox support frame 71 to be separated. Therefore, in this embodiment, the forced heat dissipation and lubrication device further includes a first shock absorber 61 (refer to Figure 2 ), the first shock absorber 61 is arranged between the cooling structure 3 and the gear box support frame 71, the first shock absorber 61 is connected to the cooling structure 3 and the gear box support frame 71 respectively, and further, a second shock absorber 62 is arranged between the gear box support frame 71 and the box body 7 (reference Figure 2 ), the first shock absorber 61 and the second shock absorber 62 cooperate to effectively isolate vibration, reduce the impact of high-frequency vibration on the cooling structure 3, and improve the reliability of the cooling structure 3.

[0066] Those skilled in the art will appreciate that, in other embodiments, only the first shock absorber 61 or the second shock absorber 62 may be included, which can also play a role in vibration isolation, reduce the impact of high-frequency vibration on the cooling structure 3, and improve the reliability of the cooling structure 3.

[0067] Because the lubricating oil enters the cooling structure 3 from the bottom of the housing 7, it may contain impurities that could clog the cooling structure 3. To prevent this from blocking the lubricating oil, a one-way valve is provided within the radiator in this embodiment, allowing the lubricating oil to flow out directly. If the pressure differential between the inlet and outlet of the cooling structure 3 exceeds a certain value due to blockage or other reasons, the lubricating oil will open the one-way valve within the cooling structure 3 and flow directly out of the cooling structure 3, bypassing the internal heat exchange structure for cooling. The integration of the one-way valve within the radiator reduces the size of the forced heat dissipation and lubrication device.

[0068] After cooling, the lubricating oil returns to the box 7 through the oil return pipe 4. In order to ensure that the gear meshing parts and bearings are lubricated with lubricating oil, the forced heat dissipation lubrication device in this embodiment also includes a distribution structure, such as Figure 2-8 As shown, the distribution structure includes a master distributor 51 and slave distributors connected to the master distributor 51. The master distributor 51 is connected to the other end of the oil return pipe 4, and the slave distributors respectively provide cooled lubricating oil to the lubricated components within the vibration gearbox. Preferably, in this embodiment, the master distributor 51 and the slave distributors are each a three-way valve, a four-way valve, or a five-way valve. Those skilled in the art will appreciate that in other embodiments, the master distributor 51 and the slave distributors may be multi-way valves.

[0069] Optionally, the slave distributor includes a first distributor 52, a second distributor 53, a third distributor 54 and a fourth distributor 55, and the main distributor 51 is connected to the first distributor 52 and the second distributor 53 respectively. The main distributor 51 distributes the cooled lubricating oil to the first distributor 52 and the second distributor 53, and the first distributor 52 and the second distributor 53 then distribute the cooled lubricating oil. The first distributor 52 is connected to multiple third distributors 54, and the second distributor 53 is connected to multiple fourth distributors 55, wherein the third distributor 54 and the fourth distributor 55 distribute lubricating oil to the bearings arranged in the box body 7, and the first distributor 52 and the second distributor 53 also distribute lubricating oil to the gears located in the box body 7. The first distributor 52 is connected to the third distributor 54 through the distribution oil pipe 57, and the second distributor 53 is connected to the fourth distributor 55 through the distribution oil pipe 57. The first distributor 52 and the second distributor 53 are also connected to the lubrication nozzle 56 through the distribution oil pipe 57. The lubrication nozzle 56 passes through the box 7 and can spray cooled lubricating oil toward the meshing part of the gear.

[0070] It should be noted that, those skilled in the art will understand that the first distributor 52 is connected to the third distributor 54 and the lubrication nozzle 56 at the same time, and the second distributor 53 is connected to the fourth distributor 55 and the lubrication nozzle 56 at the same time. The lubrication nozzle 56 connected to the first distributor 52 and the lubrication nozzle 56 connected to the second distributor 53 are arranged in different positions. The lubrication nozzle 56 connected to the first distributor 52 is arranged on the side of the vibration gearbox where the power mechanism 85 is provided, and the lubrication nozzle 56 connected to the second distributor 53 is arranged on the other side of the vibration gearbox.

[0071] The main distributor 51 and the slave distributor cooperate to redistribute the cooled lubricating oil to the bearings and gear meshing of the vibration gearbox, thereby forcibly cooling and lubricating the bearings and gears, ensuring sufficient and reliable lubrication of the bearings and gears and improving reliability.

[0072] like Figure 2-6 As shown, the number of the main distributor 51, the first distributor 52 and the second distributor 53 is one each, while the number of the third distributor 54 and the fourth distributor 55 is two each. A third distributor 54 is connected to both sides of the first distributor 52, and a fourth distributor 55 is connected to both sides of the fourth distributor 55.

[0073] Continue to refer Figure 2 The bearing end caps include a first bearing end cap 72, a second bearing end cap 73, and a third bearing end cap 74. The first bearing end cap 72 and the third bearing end cap 74 are respectively disposed at both ends of the driven eccentric shaft 83, while the second bearing end cap 73 and the third bearing end cap 74 are respectively disposed at both ends of the main eccentric shaft 81. Correspondingly, the bearings include a first bearing 75, a second bearing, and a third bearing. The first bearing 75 corresponds to the first bearing end cap 72, the second bearing corresponds to the second bearing end cap 73, and the third bearing corresponds to the third bearing end cap 74. The first bearing 75 and the third bearing are respectively disposed at both ends of the driven eccentric shaft 83, while the second bearing and the third bearing are respectively disposed at both ends of the main eccentric shaft 81.

[0074] The second bearing end cap 73 is provided at the end of the main eccentric shaft 81 connected to the power mechanism 85. The second bearing end cap 73 is provided with a second mounting hole, through which the power mechanism 85 is fixedly mounted on the second bearing end cap 73. The third bearing end cap 74 is provided with a third lubricating oil hole, which is connected to the fourth distributor 55 through the distribution oil pipe 57.

[0075] Optionally, in this embodiment, if Figure 6As shown, the bearing pressure plate 721 of the first bearing end cap 72 is provided with a first lubricating oil hole 7211 for lubricating oil to enter. The first bearing end cap 72 is connected to the third distributor 54 via a distribution oil pipe 57. One end of the distribution oil pipe 57 extends into the first lubricating oil hole 7211, connecting the return oil pipe 4 with the first lubricating oil hole 7211. The cooled lubricating oil in the return oil pipe 4 enters the first lubricating oil hole 7211 through the first distributor 52 and the third distributor 54 and is sprayed onto the bearing. The lubricating oil lubricates the bearing. Because the lubricating oil has been cooled, the cooled lubricating oil also plays a certain cooling role during the high-speed rotation of the bearing. This reduces deformation of the bearing and effectively reduces the bearing's seizure rate. Because the lubricating oil sprayed onto the bearing has been cooled, the lubricating properties of the lubricating oil are not significantly changed, ensuring good lubrication and preventing damage to the bearing.

[0076] There are two first lubricating oil holes 7211. The third distributor 54 located on one side of the first distributor 52 distributes lubricating oil to the two first lubricating oil holes 7211 at the same time, and the third distributor 54 located on the other side of the first distributor 52 distributes lubricating oil to the bearings that cooperate with the main transmission shaft.

[0077] In order to facilitate the fixed installation of the driving pump 1, in this embodiment, a first mounting hole 7212 is further provided on the bearing pressure plate 721. There are two first mounting holes 7212, and the driving pump 1 is fixedly set on the bearing pressure plate 721 through the first mounting holes 7212.

[0078] The vibration gearbox vibrates at a high frequency under the action of the main transmission shaft and the auxiliary transmission shaft, and stirs the lubricating oil inside it to form oil mist, which falls on the bearing seat 722. In order to reuse the lubricating oil, Figure 7 As shown, in this embodiment, the bearing seat 722 of the first bearing end cover 72 is provided with an oil reservoir 7221, and the bottom of the oil reservoir 7221 is provided with second lubricating oil holes 7222. The second lubricating oil holes 7222 are located at both ends of the bottom of the oil reservoir 7221. Lubricating oil accumulates in the oil reservoir 7221 and flows to the bearing through the second lubricating oil holes 7222 to lubricate the bearing.

[0079] Alternatively, as Figure 8 As shown, in this embodiment, the bearing seat 722 of the first bearing end cover 72 is further provided with an oil outlet hole 7223, and the oil outlet hole 7223 is located below the bearing seat 722. The oil outlet hole 7223 is arranged along the axial direction of the bearing seat 722. It should be noted that the height of the oil outlet hole 7223 is higher than the bottom of the bearing seat 722. The oil outlet hole 7223 is located on both sides of the bottom of the bearing seat 722. The oil outlet hole 7223 is arranged along the radial direction of the bearing seat 722, and the angle α between the oil outlet hole 7223 and the vertical generatrix of the bearing seat 722 is in the range of 0°-20° (for specific reference, see Figure 9 ).

[0080] After lubricating the bearings through the first lubricating oil hole 7211 in the bearing pressure plate 721, the lubricating oil accumulates between the bearing pressure plate 721 and the bearing seat 722, and then falls back to the bottom of the vibration gearbox through the oil outlet hole 7223 in the bearing seat 722. The lubricating oil sprayed onto the gear meshing area naturally scatters to the bottom of the vibration gearbox; the lubricating oil at the bottom of the vibration gearbox is drawn out by the oil suction structure 2 and enters the cooling structure 3. The cooled lubricating oil returns to the vibration gearbox through the oil return pipe 4, achieving the purpose of circulating and cooling the lubricating oil.

[0081] like Figure 2 and Figure 4 As shown, the oil suction structure 2 includes a filter 21, an oil suction pipe 22, and an oil inlet pipe 23. The filter 21 is disposed at the bottom of the vibration gearbox. One end of the oil suction pipe 22 is connected to the filter 21, and the other end is connected to the oil inlet of the drive pump 1. The oil outlet of the drive pump 1 is connected to the cooling structure 3 via the oil inlet pipe 23. Furthermore, the filter 21 includes a filter block and a filter screen. The filter block is provided with a through hole for installing the filter screen. One end of the oil suction pipe 22 is inserted into the filter 21. The lubricating oil is filtered through the filter screen and then enters the oil suction pipe 22. The filter 21 can filter out impurities in the lubricating oil, preventing the cooling structure 3 from being blocked and affecting its use.

[0082] The working process of the above-mentioned forced heat dissipation lubrication device is as follows:

[0083] The power mechanism 85 drives the main transmission shaft to rotate. Since the secondary transmission shaft is connected to the main transmission shaft, the secondary transmission shaft also rotates with the main transmission shaft. The driving pump 1 is connected to the secondary transmission shaft. The driving pump 1 starts to work under the drive of the secondary transmission shaft. The driving pump 1 sucks the lubricating oil at the bottom of the box body 7 through the filter element 21 and the oil suction pipe 22, and pumps the lubricating oil into the cooling structure 3. The cooling structure 3 cools the lubricating oil by contacting it with the air, thereby cooling the lubricating oil.

[0084] After cooling, the lubricating oil passes through the return oil pipe 4 and the main distributor 51. The main distributor 51 distributes it to the first distributor 52 and the second distributor 53 through the distribution oil pipe 57. The first distributor 52 then distributes the distributed cooled lubricating oil to the third distributor 54 located on both sides of the first distributor 52. The two third distributors 54 are then sprayed onto the corresponding bearings through the distribution oil pipe 57. The second distributor 53 distributes the distributed cooled lubricating oil to the fourth distributor 55 located on both sides of the second distributor 53. The two fourth distributors 55 are sprayed into the oil holes of the third bearing end cover 74 through the distribution oil pipe 57. At the same time, the two fourth distributors 55 are also sprayed to the gear meshing point through the lubrication nozzle 56, thereby realizing forced lubrication of the internal structure of the vibration gearbox.
