Description

Technical Field

[0001] The present invention relates to a hydraulic double-swing boom system, in particular to a hydraulic double-swing boom system applied in the field of lifting equipment. Background Art

[0002] In cranes, the slewing boom is usually used in conjunction with the main boom. The main boom is responsible for providing vertical height, while the slewing boom provides horizontal extension and positioning. The slewing reducer is an indispensable component of the slewing boom. Existing slewing reducers are all equipped with a single reducer, which has low working efficiency. The load of the slewing reducer is high. After working for a long time, the temperature inside the reducer will rise rapidly, causing deformation and damage of the components.

[0003] In order to solve the problem of rapid increase in temperature inside the reducer, a certain rotary reducer on the market adopts a design that allows lubricating oil to circulate, and has a certain market share.

[0004] The specification of Chinese patent CN202210246772.8 discloses a high radial load rotary reducer, which includes a base, one end of the base is connected to a motor, the other end of the base is connected to a vortex cover and an oil delivery tank, the upper end of the base is connected to an end cover, a slewing bearing is arranged in the end cover, one end of the vortex cover and the oil delivery tank is connected to a functional box, an oil delivery assembly is arranged in the oil delivery tank, the oil delivery assembly utilizes the original power of the device to realize the circulation of lubrication, the functional box is provided with a cooling filter assembly and a chip removal assembly, the cooling filter assembly can perform cooling filtration treatment when the device is in forward and reverse rotation, and collects and processes iron chips while filtering, and the chip removal assembly recycles the lubricating oil while collecting the iron chips to avoid the loss of the lubricating oil.

[0005] Although the above-mentioned reducer is provided with a structure for circulating cooling and filtering the lubricating oil, the structure is relatively complex and difficult to maintain, and the heat dissipation effect is also limited. It cannot be adaptively changed according to the changes in the internal temperature of the reducer, and it is difficult to meet the heat dissipation requirements when the reducer temperature is high. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to improve the heat dissipation and filtration of the lubricating oil inside the rotary reducer.

[0007] In order to solve the above problems, the present invention provides a hydraulic double-swing boom system, comprising a boom swivel seat, a boom is rotatably connected to the boom swivel seat, and one end of the boom away from the boom swivel seat is rotatably connected to the forearm swivel seat, the bottom of the boom swivel seat and the bottom of the forearm swivel seat are respectively rotatably connected to the boom lifting cylinder and the forearm lifting cylinder, and the boom lifting cylinder and the forearm lifting cylinder are respectively rotatably connected to the lower side wall of the boom through the cylinder pin shaft, a double-swing reducer is installed on the upper side wall of the forearm swivel seat, and the forearm is installed on the double-swing reducer, the double-swing reducer includes a swivel bearing, and a reducer body is installed on both sides of the swivel bearing, and a driving motor is installed at one end of the reducer body;

[0008] An oil circuit circulator is fixedly connected to the side wall of the reducer body, and the oil circuit circulator includes a base, and an oil pump and an oil delivery pump are respectively installed at both ends of the base, and the oil pump and the oil delivery pump are respectively connected to the inside of the reducer body and form a lubricating oil circulation loop, and a circulation cavity is opened on the inner wall of the base, and the two ends of the circulation cavity are respectively connected to the oil pump and the oil delivery pump, and a plurality of cylindrical cavities distributed at equal intervals are opened on the inner wall of the base, and a shape switching radiator is inserted in each cylindrical cavity, and a semiconductor cooling sheet is installed at the bottom of each cylindrical cavity, and the semiconductor cooling sheet fits the bottom of the shape switching radiator;

[0009] The morphology-switching radiator includes a cooling upper seat and a cooling base which are distributed up and down. The upper side wall of the cooling upper seat is rotatably connected to a sealing top seat with a hexagonal screw hole on the upper end, and the sealing top seat is threadedly sealed to the inner wall of the base. Two symmetrically distributed heat exchange plates are connected between the cooling upper seat and the cooling base. A composite filter plate is fixedly connected between the ports of the two heat exchange plates, and the composite filter plate is arranged opposite to the circulation cavity. A cooling column is also fixedly connected between the cooling upper seat and the cooling base, and the cooling column is located at the center point of the cooling base.

[0010] In the above-mentioned hydraulic double-swing boom system, the working efficiency is effectively improved by arranging a double-swing reducer, and an adaptive heat dissipation and filtering device is added on the basis of the reducer.

[0011] As a further improvement of the present application, a temperature sensor is installed inside the reducer body, and a high-temperature warning module is electrically connected to the temperature sensor. The oil circuit circulator also includes a self-cleaning module and an adaptive heat dissipation adjustment module electrically connected to the high-temperature warning module, and the adaptive heat dissipation adjustment module is electrically connected to the oil pump, the oil pump and the semiconductor refrigeration plate through the control processor. The temperature sensor monitors the temperature inside the reducer body in real time. When the temperature exceeds the set threshold, the high-temperature warning module is triggered, and the high-temperature warning module further triggers the adaptive heat dissipation adjustment module. The adaptive heat dissipation adjustment module, on the one hand, accelerates the circulation flow speed of the lubricating oil by increasing the rotation speed of the oil pump and the oil pump, and on the other hand, controls the semiconductor refrigeration plate to perform lower temperature cooling. The two cooperate with each other to effectively improve the heat dissipation of the lubricating oil, thereby indirectly reducing the temperature inside the reducer.

[0012] As a further improvement of the present application, the upper and lower ends of the two heat exchange plates are fixedly connected with T-shaped sliders, and the side walls of the cooling upper seat and the cooling base are provided with guide grooves matching the T-shaped sliders, the side walls of the cooling column facing the heat exchange plate are provided with multiple equally spaced telescopic grooves, and the side walls of the heat exchange plate are fixedly connected with telescopic rods that are sealed and slidably connected to the inner walls of the telescopic grooves, and a shape memory alloy belt is fixedly connected between the inner walls of the telescopic grooves and the telescopic rods. When the adaptive heat dissipation adjustment module controls the semiconductor refrigeration plate to further lower the cooling temperature, the cold energy is transferred to the shape memory alloy belt through the cooling base and the cooling column. The shape memory alloy strip, the lower temperature of the cold makes the shape memory alloy strip deform, and the shape memory alloy strip begins to change back to the contracted state from the original elongated state. At this time, the deformation of the shape memory alloy strip makes the telescopic rod pull the two heat exchange plates to move toward each other until the two heat exchange plates are merged together. The diameter of the combined two heat exchange plates becomes smaller. At this time, a gap is generated between the combination and the cylindrical cavity. The lubricating oil changes from passing through the inside of the shape switching radiator to flowing outside the shape switching radiator, which effectively increases the circulation speed of the lubricating oil, thereby effectively improving the heat dissipation effect.

[0013] As a further improvement and supplement to the present application, a driving cavity is opened on the side wall of the composite filter plate facing the cooling column, and a concave cam rotating mechanism electrically connected to the self-cleaning module is installed in the driving cavity, the inner wall of the driving cavity is sealed and slidably connected with a moving pad that abuts against the concave cam rotating mechanism, the inner wall of the driving cavity is slidably connected with a cleaning plate fixedly connected to the moving pad, and the cleaning plate extends to the outside of the driving cavity, and a plurality of symmetrically distributed elastic bands are also fixedly connected between the moving pad and the inner wall of the driving cavity. When the high temperature warning module triggers the adaptive heat dissipation adjustment module, the self-cleaning module is also triggered. The self-cleaning module starts the concave cam rotating mechanism to rotate. During the rotation of the concave cam rotating mechanism, the moving pad is continuously pushed, and the rebound effect of the elastic band makes the moving pad reciprocate back and forth, so that the cleaning plate repeatedly hits the composite filter plate, so that after the composite filter plate is gathered in by the two merged heat exchange plates, the purpose of cleaning the debris accumulated on the composite filter plate can be achieved, thereby effectively improving the filtration efficiency of the composite filter plate.

[0014] As a further improvement of the present application, the cooling base, heat exchange plate and cooling column are all made of high thermal conductivity materials, and the side walls of the cooling column are also fixedly connected with a plurality of heat exchange columns distributed around with equal intervals. The cold energy generated by the semiconductor refrigeration plate is transferred to the cooling base and the heat exchange plate, so as to dissipate heat and cool the lubricating oil. The cooling base transfers the cold energy to the cooling column, and the cooling column then transfers the cold energy to the heat exchange column. In this way, the heat exchange columns dispersed around the cooling column can increase the contact area with the lubricating oil, thereby further effectively improving the heat dissipation effect.

[0015] As another improvement of the present application, the composite filter plate includes a porous elastic base layer, and the side walls of the porous elastic base layer are fixedly connected with debris filtering layers. Since the lubricating oil will have a certain impact on the composite filter plate during the circulation process, in order to prevent the composite filter plate from being deformed and unable to be retracted, the porous elastic base layer is used to shape it, and the porous elastic base layer can rebound when the cleaning plate repeatedly hits it, which will generate vibration and effectively improve the cleaning effect.

[0016] As another improvement of the present application, the side wall of the cooling upper seat is also covered with a sealing ring, and the upper end side wall of the cooling upper seat is also bonded with a thermal insulation film. The sealing ring is to prevent the lubricating oil from leaking out of the gap, and the thermal insulation film can effectively prevent the external temperature from being transferred to the inside and affecting the temperature balance, especially in the hot summer, which can effectively prevent the external heat from being transferred to the inside.

[0017] In summary, by setting up a double-swing reducer to effectively improve the working efficiency of the slewing arm, the workload of a single reducer can be effectively reduced, and by adding a form-switching radiator to cool and filter the circulating lubricating oil, when the lubricating oil temperature rises abnormally, the form-switching radiator can adaptively change its form from a heat dissipation and filtration state to a pure heat dissipation state, thereby increasing the circulation speed of the lubricating oil, thereby effectively improving the heat dissipation effect, and the composite filter can also be cleaned during the form-changing period of the form-switching radiator, thereby effectively improving the filtering effect.

The sealing ring is to prevent lubricating oil from leaking out of the gap. The heat insulation film can effectively prevent the external temperature from being transferred to the inside and affecting the temperature balance, especially in the hot summer, which can effectively prevent the external heat from being transferred to the inside;

[0038] Figure 3 , 6 and Fig.14As shown, the morphology switching radiator 10 includes a cooling upper seat 11 and a cooling base 12 which are distributed up and down, the upper side wall of the cooling upper seat 11 is rotatably connected to a sealing top seat 13 with a hexagonal screw hole on the upper end, and the sealing top seat 13 is threadedly sealed with the inner wall of the base 901, two symmetrically distributed heat exchange plates 14 are connected between the cooling upper seat 11 and the cooling base 12, a composite filter plate 16 is fixedly connected between the ports of the two heat exchange plates 14, and the composite filter plate 16 is arranged opposite to the circulation chamber 9011, the composite filter plate 16 includes a porous elastic base layer 1601 (preferably polyurethane elastic material, and other materials can also be selected according to actual needs), and the side walls on both sides of the porous elastic base layer 1601 are fixedly connected to debris filter layers 1602 (preferably polyester fiber material, and other materials can also be selected according to actual needs), because the lubricating oil will have a certain impact on the composite filter plate 16 during the circulation process, in order to prevent the composite filter plate 16 from The deformation occurs and it cannot be retracted, so the porous elastic base layer 1601 is used to shape it, and the porous elastic base layer 1601 can rebound when the cleaning plate 22 repeatedly knocks it, which will generate vibration and effectively improve the cleaning effect. A cooling column 17 is fixedly connected between the cooling upper seat 11 and the cooling base 12, and the cooling column 17 is located at the center point of the cooling base 12. The cooling base 12, the heat exchange plate 14 and the cooling column 17 are all made of high thermal conductivity materials, and the side wall of the cooling column 17 is also fixedly connected with a plurality of heat exchange columns 24 distributed around at equal intervals. The cold energy generated by the semiconductor refrigeration plate 25 is transferred to the cooling base 12 and the heat exchange plate 14, so as to dissipate heat and cool the lubricating oil. The cooling base 12 transfers the cold energy to the cooling column 17, and the cooling column 17 further transfers the cold energy to the heat exchange column 24. In this way, the heat exchange columns 24 dispersed around the cooling column 17 can increase the contact area with the lubricating oil, thereby further effectively improving the heat dissipation effect.

[0039] The second implementation method:

[0040] Fig. 9 , 10It is shown that a temperature sensor is installed inside the reducer body 702 (the specific model is selected according to actual needs and will not be described in detail here), and a high-temperature warning module is electrically connected to the temperature sensor. The oil circuit circulator 9 also includes a self-cleaning module and an adaptive heat dissipation adjustment module electrically connected to the high-temperature warning module, and the adaptive heat dissipation adjustment module is electrically connected to the oil pump 902, the oil pump 903 and the semiconductor cooling plate 25 through the control processor (the specific connection structure and control principle of this part are well-known technologies for technicians in the relevant field and will not be described in detail here). The temperature sensor monitors the temperature inside the reducer body 702 in real time. When the temperature exceeds the set threshold, the high-temperature warning module is triggered, and the high-temperature warning module further triggers the adaptive heat dissipation adjustment module. The adaptive heat dissipation adjustment module, on the one hand, accelerates the circulation speed of the lubricating oil by increasing the rotation speed of the oil pump 902 and the oil pump 903, and on the other hand, controls the semiconductor cooling plate 25 to perform lower temperature cooling. The two cooperate with each other to effectively improve the heat dissipation of the lubricating oil, thereby indirectly reducing the temperature inside the reducer;

[0041] Figure 7 , 8 , 11 and Fig.12 As shown, the upper and lower ends of the two heat exchange plates 14 are fixedly connected with T-shaped sliders 15, and the side walls of the cooling upper seat 11 and the cooling base 12 are provided with guide grooves 1501 matching the T-shaped sliders 15, the cooling column 17 is provided with a plurality of equally spaced telescopic grooves 1701 on the side walls of the heat exchange plates 14, and the side walls of the heat exchange plates 14 are fixedly connected with telescopic rods 18 that are sealed and slidably connected with the inner walls of the telescopic grooves 1701, and a shape memory alloy belt 19 is fixedly connected between the inner walls of the telescopic grooves 1701 and the telescopic rods 18 (the deformation temperature is selected and set according to actual needs and will not be described in detail here). When the adaptive heat dissipation adjustment module controls the semiconductor refrigeration plate 25 to further reduce the cooling temperature, the cooling capacity The cold is transferred to the shape memory alloy strip 19 through the cooling base 12 and the cooling column 17. The cold with a lower temperature causes the shape memory alloy strip 19 to deform. The shape memory alloy strip 19 begins to change from the original elongated state to the contracted state. At this time, the deformation of the shape memory alloy strip 19 causes the telescopic rod 18 to pull the two heat exchange plates 14 to move toward each other until the two heat exchange plates 14 are merged together. The diameter of the combined body of the two heat exchange plates 14 after the merger becomes smaller. At this time, a gap is generated between the combined body and the cylindrical cavity 9012. The lubricating oil changes from passing through the inside of the shape switching radiator 10 to flowing outside the shape switching radiator 10, which effectively improves the circulation speed of the lubricating oil, thereby effectively improving the heat dissipation effect.

[0042] Fig.12 , 13As shown, a driving cavity 1702 is opened on the side wall of the cold-conducting column 17 facing the composite filter plate 16, and a concave cam rotating mechanism 20 electrically connected to the self-cleaning module is installed in the driving cavity 1702 (it is a prior art, and the main structure is composed of a driving motor and a concave cam, which is a well-known technology for technicians in the mechanical field and will not be described in detail here), and the inner wall of the driving cavity 1702 is sealed and slidably connected to a moving pad 21 that abuts against the concave cam rotating mechanism 20, and the inner wall of the driving cavity 1702 is slidably connected to a cleaning plate 22 fixedly connected to the moving pad 21, and the cleaning plate 22 extends to the outside of the driving cavity 1702, and a plurality of symmetrically distributed elastic The elastic band 23 (oil-resistant rubber material is preferred, and other materials can also be selected according to actual needs) triggers the self-cleaning module at the same time as the high temperature warning module triggers the adaptive heat dissipation adjustment module. The self-cleaning module starts the concave cam rotating mechanism 20 to rotate. During the rotation of the concave cam rotating mechanism 20, the moving pad 21 is continuously pushed. The rebound effect of the elastic band 23 makes the moving pad 21 reciprocate back and forth, and then the cleaning plate 22 repeatedly hits the composite filter plate 16. In this way, after the composite filter plate 16 is gathered in by the two merged heat exchange plates 14, the purpose of cleaning the debris gathered on the composite filter plate 16 can be achieved, thereby effectively improving the filtering efficiency of the composite filter plate 16.

[0043] The working principle of this scheme is as follows: first, under normal heat dissipation state, the oil pump 902 draws the lubricating oil inside the reducer body 702 into the circulation chamber 9011, and the lubricating oil flows through the circulation chamber 9011 through multiple shape-switching radiators 10 and then is transported back to the reducer body 702 by the oil delivery pump 903. The shape-switching radiator 10 dissipates heat and filters the lubricating oil in this process. At this time, the shape-switching radiator 10 has not yet changed in shape. The heat exchange plates 14 on both sides are tightly attached to the inner wall of the cylindrical cavity 9012. The lubricating oil enters the interior of the shape-switching radiator 10 through the composite filter plate 16, and then passes through the composite filter plate 16 on the other side. The two composite filter sheets 16 are combined to go out. In this process, the two composite filter sheets 16 intercept the debris carried in the lubricating oil, thereby playing a filtering role. When the temperature sensor detects that the temperature inside the reducer body 702 rises rapidly and exceeds the set threshold, the high temperature warning module is immediately triggered. The high temperature warning module then triggers the adaptive heat dissipation adjustment module. The adaptive heat dissipation adjustment module accelerates the circulation speed of the lubricating oil by increasing the rotation speed of the oil pump 902 and the oil delivery pump 903 on the one hand, and controls the semiconductor refrigeration sheet 25 to perform lower temperature cooling on the other hand. The two cooperate with each other to effectively improve the heat dissipation of the lubricating oil, thereby indirectly reducing the temperature inside the reducer;

[0044] When the adaptive heat dissipation adjustment module controls the semiconductor refrigeration plate 25 to further reduce the cooling temperature, the cold energy is transferred to the shape memory alloy belt 19 through the cooling base 12 and the cooling column 17. The lower temperature cold energy causes the shape memory alloy belt 19 to deform, and the shape memory alloy belt 19 begins to change from the original elongated state to the contracted state. At this time, the deformation of the shape memory alloy belt 19 causes the telescopic rod 18 to pull the two heat exchange plates 14 to move toward each other until the two heat exchange plates 14 are merged together. The diameter of the combined body of the two heat exchange plates 14 becomes smaller. At this time, a gap is generated between the heat exchange plate 14 and the cylindrical cavity 9012, and the lubricating oil changes from passing through the inside of the shape switching radiator 10 to passing through the outside of the shape switching radiator 10. The flow of the lubricating oil is eliminated, and the filtering procedure is omitted, which effectively improves the speed of the circulation flow of the lubricating oil, thereby further effectively achieving the heat dissipation effect. In addition, when the high temperature warning module triggers the adaptive heat dissipation adjustment module, it also triggers the self-cleaning module, and the self-cleaning module starts the concave cam rotating mechanism 20 to rotate. During the rotation of the concave cam rotating mechanism 20, the moving pad 21 is continuously pushed, and the rebound effect of the elastic band 23 makes the moving pad 21 reciprocate back and forth, so that the cleaning plate 22 repeatedly knocks the composite filter plate 16, so that after the composite filter plate 16 is gathered in by the two merged heat exchange plates 14, the purpose of cleaning the debris gathered on the composite filter plate 16 can be achieved, thereby effectively improving the filtering efficiency of the composite filter plate 16;

[0045] When it is necessary to clean and maintain the shape-switching radiator 10, the sealing top seat 13 is unscrewed by the hexagonal bolt, the shape-switching radiator 10 is pulled out to rinse the composite filter 16, and then the shape-switching radiator 10 is reinserted into the cylindrical cavity 9012 after rinsing, and finally the sealing top seat 13 is tightened to complete the operation.

[0046] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
