Specific embodiments

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] The present invention provides an aerial work device 100 and an aerial work vehicle, which can facilitate the operator to inject oil into the slewing mechanism 20, improving the work efficiency and safety.

[0028] Referring to Figures 1 to 4 , according to the aerial work device 100 of the embodiment of the present invention, the aerial work device 100 includes a work platform 10, a slewing mechanism 20 and a connecting seat 30. The slewing mechanism 20 is connected to the work platform 10, and the slewing mechanism 20 drives the work platform 10 to rotate. The connecting seat 30 is connected to the slewing mechanism 20. Among them, the aerial work device 100 further includes an oil injection passage, the inlet of the oil injection passage is arranged on the connecting seat 30 and the outlet is arranged on the slewing mechanism 20, for injecting oil from the connecting seat 30 to the slewing mechanism 20; in this way, the work efficiency and safety can be improved.

[0029] Specifically, during high-altitude operation, the slewing mechanism 20 is respectively connected to the work platform 10 and the connecting seat 30, and drives the work platform 10 to rotate relative to the connecting seat 30. The connecting seat 30 can be connected to the lifting mechanism, and the overall high-altitude operation device 100 can be lifted and lowered through the lifting mechanism; with long-term high-altitude operation, in order to improve the operating efficiency and service life of the slewing mechanism 20, lubricating grease needs to be injected into the slewing mechanism 20; in the related art, generally, a detachable mounting plate is provided on the work platform 10, and the oil injection point of the slewing mechanism 20 is exposed by disassembling the mounting plate, and the operator can inject oil into the slewing mechanism 20 through the oil injection point. However, the above operation requires the disassembly and assembly of the mounting plate, and multiple disassembly and assembly will affect the connection stability of the mounting plate and cause connection failure; therefore, in the embodiment of the present invention, an oil injection channel can be provided in the high-altitude operation device 100, the inlet of the oil injection channel is arranged on the connecting seat 30, and the outlet of the oil injection channel is arranged on the slewing mechanism 20. In this way, when oil injection is required, the operator can inject oil into the slewing mechanism 20 through the inlet of the oil injection channel on the connecting seat 30, improving convenience and eliminating the need to enter the work platform 10 to disassemble the mounting plate, thereby improving the operation efficiency and safety.

[0030] Therefore, for the high-altitude operation device 100 according to the embodiment of the present invention, oil can be injected into the slewing mechanism 20 from the connecting seat 30, which is convenient for the operator to inject oil into the slewing mechanism 20 and improves the operation efficiency and safety.

[0031] Refer to Figure 1 and Figure 3 , in some embodiments of the present invention, the connecting seat 30 is arranged below the work platform 10 and supports the work platform 10; in this way, the convenience and safety of oil injection can be further improved.

[0032] Specifically, since the mounting plate is arranged on the work platform 10, generally, the operator needs to enter the work platform 10 to disassemble the mounting plate, which brings inconvenience to the oil injection of the slewing mechanism 20; therefore, the connecting seat 30 can be arranged below the work platform 10. After the lifting mechanism drives the connecting seat 30 to descend, the operator standing on the road surface can inject oil into the slewing mechanism 20 through the connecting seat 30 from below the work platform 10, further improving the convenience and safety of oil injection. Moreover, the work platform 10 can be supported through the connecting seat 30, improving the high-altitude operation stability of the work platform 10.

[0033] Refer to Figure 1 , Figures 3 to 5 , in some embodiments of the present invention, the high-altitude operation device 100 further includes an oil cup 50, and the oil cup 50 is arranged on the connecting seat 30 and connected to the inlet of the oil injection channel; in this way, it is convenient for the operator to inject oil into the slewing mechanism 20.

[0034] Specifically, the oil cup 50 can be a straight-through pressure lubricating cup 50, a connector type pressure lubricating cup 50, a screw-cap oil cup 50, etc.; optionally, the oil cup 50 is a straight-through pressure lubricating cup 50, which includes an oil cup body and a seal. The oil cup body has an oil nozzle, and the seal closes the oil nozzle when not refueling. When it is necessary to refuel the slewing mechanism 20, the oil nozzle can be opened by pressing to drive the seal, so that lubricating grease can be injected through the oil cup 50 and transported to the slewing mechanism 20 through the oil injection channel. After refueling is completed, the drive of the seal is released, and the seal can close the oil nozzle again, which is convenient for refueling.

[0035] Referring Figure 1 and Figure 4 , in some embodiments of the present invention, the aerial work device 100 further includes a positioning member 60. The oil cup 50 is connected to the positioning member 60, and the positioning member 60 and the connecting seat 30 are connected by a fastener 70. In this way, the oil cup 50 is positioned on the connecting seat 30 through the positioning member 60, which can improve the installation strength of the oil cup 50 on the connecting seat 30. When docking and installing with the oil nozzle of the oil cup 50, the oil cup 50 can remain stationary relative to the connecting seat 30, which is convenient for the refueling operation and improves the refueling convenience.

[0036] In some examples, the outer peripheral surface of the oil cup 50 is provided with threads, and the positioning member 60 is provided with a connecting hole. The oil cup 50 can be inserted into the connecting hole, and a nut is connected to the outer peripheral surface of the oil cup 50, so as to connect the positioning member 60 to the oil cup 50. The positioning member 60 and the connecting seat 30 can be connected together by a fastener 70, so as to fixedly connect the oil cup 50 to the connecting seat 30, which is convenient for refueling operation through the oil cup 50.

[0037] Referring Figure 1 , in some embodiments of the present invention, the slewing mechanism 20 further includes a slewing bearing 21. The slewing bearing 21 includes an inner ring 211, an outer ring 212 and a raceway between the inner ring 211 and the outer ring 212. Rolling elements are provided in the raceway, and the rolling elements can roll relative to the inner ring 211 and the outer ring 212, so that the inner ring 211 can rotate relative to the outer ring 212. One of the inner ring 211 and the outer ring 212 is connected to the working platform 10, and the other is connected to the connecting seat 30. The outlet of the oil injection channel is provided in the slewing bearing 21 and communicates with the raceway. In this way, when the operator performs the refueling operation, lubricating grease can be injected into the raceway in the slewing bearing 21 through the oil injection channel, thereby improving the service life and operating efficiency of the slewing mechanism 20.

[0038] Of course, according to the actual situation, the slewing mechanism 20 further includes a driving member 22 and a gear transmission group. The driving member 22 is arranged on the connecting seat 30 and is in transmission connection with the gear transmission group. The gear transmission group is arranged on the connecting seat 30 and is in transmission connection with the working platform 10. The driving member 22 inputs power to the gear transmission group, and the gear transmission group outputs power to the working platform 10 to drive the working platform 10 to rotate relative to the connecting seat 30. Among them, the outlet of the oil injection channel can be communicated with the inside of the gear transmission group. In this way, when the operator performs the oil injection operation, lubricating grease can be injected into the gear transmission group through the oil injection channel, thereby improving the service life and operating efficiency of the slewing mechanism 20.

[0039] Specifically, the gear transmission group of the slewing mechanism 20 can be driven in the form of a worm and worm gear slewing drive or in the form of a spur gear slewing drive. For example, the gear transmission group includes a worm wheel and a worm. The worm wheel is in transmission connection with the worm, the worm is in transmission connection with the driving member 22, and the worm wheel is in transmission connection with the working platform 10, thereby driving the working platform 10 to rotate relative to the connecting seat 30. Another example is that the gear transmission group includes a driving gear and a driven gear. The driving gear is in transmission connection with the driven gear, the driving gear is in transmission connection with the driving member 22, and the driven gear is in transmission connection with the working platform 10, thereby driving the working platform 10 to rotate relative to the connecting seat 30.

[0040] Refer to Figure 1 , in some embodiments of the present utility model, the inner ring 211 of the slewing bearing 21 is connected to the connecting seat 30, the outer ring 212 of the slewing bearing 21 is connected to the working platform 10, and the outlet of the oil injection channel is arranged on the inner ring 211. In this way, the safety of the oil injection operation can be improved, and the oil injection channel can be prevented from being damaged.

[0041] It can be understood that during high-altitude operation, the driving member 22 can drive the working platform 10 to rotate relative to the connecting seat 30. At this time, the outer ring 212 of the slewing bearing 21 rotates with the working platform 10, that is, the outer ring 212 of the slewing bearing 21 rotates relative to the inner ring 211 of the slewing bearing 21. In order to prevent the oil injection channel from being damaged, the outlet of the oil injection channel can be arranged on the inner ring 211 of the slewing bearing 21. In this way, during high-altitude operation, the outlet of the oil injection channel does not need to rotate with the working platform 10, resulting in damage to the oil injection channel, so as to facilitate the subsequent oil injection of the slewing mechanism 20.

[0042] Refer to Figure 1 and Figure 5, in some embodiments of the present utility model, the aerial work device 100 further includes a lubricating pipe 40. An oil injection passage is formed inside the lubricating pipe 40. One end of the lubricating pipe 40 is provided with a first joint 41, and the other end is provided with a second joint 42. The first joint 41 is connected to the connecting seat 30, and the second joint 42 is connected to the slewing mechanism 20. In this way, the oil injection point of the slewing mechanism 20 can be led to the connecting seat 30 through the lubricating pipe 40, facilitating the operator to inject oil into the slewing mechanism 20.

[0043] Specifically, one end of the lubricating pipe 40 is provided with a first joint 41. The first joint 41 can be connected to an oil cup 50. The oil cup 50 is relatively fixed on the connecting seat 30. The other end of the lubricating pipe 40 is provided with a second joint 42. The second joint 42 can be connected to the slewing mechanism 20. An oil injection passage is formed inside the lubricating pipe 40. The first joint 41 forms an inlet of the oil injection passage, and the second joint 42 forms an outlet of the oil injection passage. In this way, the operator can inject lubricating grease through the oil cup 50 on the connecting seat 30, and the lubricating grease is transported into the slewing mechanism 20 through the lubricating pipe 40.

[0044] Certainly, in some other embodiments, an oil injection passage can be formed inside the connecting seat 30. One end of the oil injection passage is opened on the outer surface of the connecting seat 30, and the other end is opened on the side of the connecting seat 30 where the slewing mechanism 20 is provided, for injecting oil from the connecting seat 30 into the slewing mechanism 20.

[0045] Refer to Figure 2 , in some embodiments of the present utility model, the connecting seat 30 is provided with a positioning hole 31. The lubricating pipe 40 passes through the positioning hole 31. The radial dimension D1 of the positioning hole 31 is not less than the outer diameter D2 of the lubricating pipe 40. In this way, it is convenient to connect the lubricating pipe 40 to the connecting seat 30 and the slewing mechanism 20, improving the assembly efficiency.

[0046] Specifically, during assembly, one end of the lubricating pipe 40 can penetrate from one side of the positioning hole 31 on the connecting seat 30 and exit from the other side of the positioning hole 31. Subsequently, one end of the lubricating pipe 40 is connected to the slewing mechanism 20, and the other end of the lubricating pipe 40 can be connected to the oil cup 50 and installed on the connecting seat 30 through a positioning member 60 to achieve assembly. Therefore, the radial dimension D1 of the positioning hole 31 can be made not less than the outer diameter D2 of the lubricating pipe 40, facilitating the lubricating pipe 40 to pass through the positioning hole 31 to improve the assembly efficiency of the lubricating pipe 40.

[0047] Refer to Figures 1 to 4 , in some embodiments of the present utility model, the inside of the connecting seat 30 is hollow and one side is open. The slewing mechanism 20 is provided on one side of the connecting seat 30 and faces the inside of the connecting seat 30. The oil injection passage is provided inside the connecting seat 30. Such a setting can facilitate the arrangement of the oil injection passage inside the connecting seat 30 and prevent the oil injection passage from being damaged due to external interference.

[0048] Specifically, the inside of the connecting seat 30 is hollow, providing layout space for the arrangement of the oil injection passage; one side of the connecting seat 30 is open, and the slewing mechanism 20 is connected to the open side of the connecting seat 30. The slewing mechanism 20 can be opposite to the inside of the connecting seat 30. The oil injection passage is arranged inside the connecting seat 30. The inlet of the oil injection passage is arranged on the outer surface of the connecting seat 30, and the outlet of the oil injection passage can be arranged on the slewing mechanism 20 through the open side of the connecting seat 30, so as to realize the transportation of lubricating grease. Moreover, the oil injection passage is hidden inside the connecting seat 30, avoiding damage to the oil injection passage caused by external environment interference.

[0049] Referring to Figures 1 to 4 , in some embodiments of the present utility model, the connecting seat 30 extends in the up and down direction and has opposite ends. The upper end of the connecting seat 30 is connected to the slewing bearing 21, and the lower end of the connecting seat 30 is connected to the vehicle body of the aerial work vehicle. The oil injection port of the oil injection passage is closer to the upper end of the connecting seat 30 than the lower end of the connecting seat 30. In this way, the relatively short lubricating pipe 40 can be connected to the connecting seat 30 and the slewing mechanism 20, reducing the cost of the lubricating pipe 40. And due to the shortening of the oil injection passage, the resistance of the lubricating grease passing through the oil injection passage is also reduced, facilitating the operator to inject oil into the slewing mechanism 20.

[0050] Referring to Figures 1 to 5 , according to the aerial work vehicle of the embodiment of the present utility model, the aerial work vehicle includes a vehicle body and the aerial work device 100 in the above embodiment. The aerial work device 100 is arranged on the vehicle body. By applying the aforementioned aerial work device 100, the operation efficiency and safety can be improved.

[0051] Specifically, during aerial work, the vehicle body can move to the corresponding work location, and the aerial work device 100 is driven to rise by the lifting mechanism. Then, the operation platform 10 can be driven to rotate relative to the connecting seat 30 through the slewing mechanism 20 to facilitate aerial work; as the aerial work device 100 is used for a long time, it is necessary to inject oil into the slewing mechanism 20 in the aerial work device 100. At this time, the operator can inject oil through the oil injection passage inlet on the connecting seat 30. The injected lubricating grease can flow along the oil injection passage and flow to the inside of the slewing mechanism 20 through the outlet of the oil injection passage, providing a lubricating medium for the slewing mechanism 20, thereby improving the operation efficiency and service life of the slewing mechanism 20. In addition, the connecting seat 30 is arranged below the operation platform 10. In this way, after the operation platform 10 descends, the operator can inject oil into the slewing mechanism 20 from below the operation platform 10 without climbing to a high place, improving convenience.

[0052] Furthermore, the inside of the connecting seat 30 is hollow and its top is open. The slewing mechanism 20 is arranged on the top of the connecting seat 30. The lubricating pipe 40 passes through the positioning hole 31 from the outside of the connecting seat 30 into the inside of the connecting seat 30. One end of the lubricating pipe 40 is connected with a first joint 41. The first joint 41 is connected to an oil cup 50. The oil cup 50 is connected to a positioning member 60. The positioning member 60 and the connecting seat 30 are connected by a fastener 70, thereby fixing one end of the lubricating pipe 40 on the connecting seat 30. The other end of the lubricating pipe 40 is connected with a second joint 42. The second joint 42 is connected to the slewing mechanism 20 through the top of the connecting seat 30. Wherein, an oil injection channel is formed inside the lubricating pipe 40. The first joint 41 forms an inlet of the oil injection channel, and the second joint 42 forms an outlet of the oil injection channel. In this way, an operator can inject oil into the slewing mechanism 20 through the oil cup 50 on the connecting seat 30. Moreover, the lubricating pipe 40 can be hidden inside the connecting seat 30 to prevent the external environment from interfering with the lubricating pipe 40.

[0053] In addition, the radial dimension D1 of the positioning hole 31 is not less than the outer diameter D2 of the lubricating pipe 40, which facilitates the lubricating pipe 40 to be inserted into the positioning hole 31 and improves the assembly efficiency of the lubricating pipe 40.

[0054] Furthermore, the slewing mechanism 20 includes a slewing bearing 21. The slewing bearing 21 includes an inner ring 211 and an outer ring 212. A raceway is formed between the inner ring 211 and the outer ring 212. Rolling elements are arranged in the raceway so that the inner ring 211 rotates relative to the outer ring 212. The second joint 42 can be connected to the slewing bearing 21 to inject lubricating grease into the slewing bearing 21, thereby improving the operating efficiency and service life of the slewing mechanism 20. In addition, the inner ring 211 of the slewing bearing 21 can be connected to the connecting seat 30, and the outer ring 212 of the slewing support can be connected to the working platform 10. In this way, when the working platform 10 rotates relative to the connecting seat 30, the lubricating pipe 40 does not need to rotate with the working platform 10, avoiding interference and entanglement of the lubricating pipe 40.

[0055] In the related art, when the slewing mechanism 20 in the aerial work device 100 needs to be oiled, it is necessary to climb into the working platform 10 and remove the mounting plate. After oiling, the mounting plate needs to be reinstalled. It is inconvenient to use and seriously affects the efficiency. In addition, the reduction gear (i.e., the slewing mechanism 20) needs to be oiled once a month and needs to be frequently disassembled. The mounting bolts are prone to slipping and failure. Moreover, the working platform 10 is a place where workers often walk. The bolts of the mounting plate protrude and are easy to trip over, affecting the use safety.

[0056] Therefore, the present utility model provides a lubrication solution for the slewing reducer of an aerial work vehicle. It can achieve convenient oiling without disassembly, without getting on the hanging basket, and can be oiled on the ground, with high use efficiency and safe operation.

[0057] Its working principle is as follows: A lubricating pipe 40 is used. One end of the lubricating pipe 40 is fixed to the oil hole of the reduction gear (i.e., the aforementioned slewing mechanism 20), and the other end is led out to the connecting seat 30.

[0058] Specifically, the aerial work device 100 includes: a hanging basket (i.e., the working platform 10), a slewing reduction gear, a connecting seat 30, a lubricating pipe 40 assembly, and a positioning plate. Among them, the lubricating pipe 40 assembly includes a straight-through oil pipe joint (i.e., the second joint 42), a lubricating pipe 40, a lubricating pipe 40 joint (i.e., the first joint 41), and an oil cup 50. The straight-through oil pipe joint at one end of the lubricating pipe 40 assembly is connected to the oil hole of the slewing reduction gear, and the other end is fixed to the positioning plate by a nut. For the convenience of installation, the connecting seat 30 is provided with a positioning hole 31 and a threaded hole.

[0059] In addition, for the convenience of installing the lubricating pipe 40, the diameter D1 of the positioning hole 31 of the connecting seat 30 is larger than the diameter D2 of the oil pipe. During installation, the oil pipe can smoothly pass through the positioning hole 31 of the connecting seat 30 and is fixed to the positioning plate by a nut, and then the positioning plate is fixed to the connecting seat 30 by two bolts to complete the installation of the lubricating pipe 40. In this way, when lubricating oil is injected into the slewing reduction gear, it can be directly injected outside. It is convenient for oil injection, with high efficiency. Moreover, there is no need to disassemble and assemble the mounting plate on the working platform 10, and there is no need to climb into the working platform 10, with high reliability and safe operation.
