Description

Technical Field

[0001] The present invention relates to the technical field of crane traveling devices, in particular to a crane trolley traveling device. Background Art

[0002] The crane trolley travel device is an important part of the crane, responsible for moving the entire crane on the horizontal plane to achieve the handling and stacking of goods. The crane trolley travel device is usually installed on a fixed track and drives the travel wheels to rotate through transmission mechanisms such as motors and reducers, thereby achieving horizontal movement of the crane.

[0003] During the operation of the crane's wheels on the track, various impurities often accumulate on the track surface because the track is usually exposed to the outside and the main working environment is located in the factory. The presence of these impurities, coupled with the fact that the crane is a large-scale mechanical equipment and its load-bearing capacity, constantly crushes the impurities on the track during the operation, causing the wheels to wear faster. It is particularly important to note that if the impurities accumulated on both sides of the track are uneven, it may cause the overall balance of the crane to be unbalanced, and in severe cases there may even be a risk of derailment. In addition, considering the significant inertia generated by the crane's own weight and large load during the braking process, it is easy to cause the wheels to slip, further aggravating the degree of wear on the wheels. Therefore, it is necessary to reduce the wear of the wheels on the track and extend the service life of the wheels.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the traveling device of the crane trolley, uniform lubrication distribution is achieved, and the first drainage groove and the second drainage groove are arranged inside the running wheel, so that the lubricating oil can be evenly distributed on the contact surface between the running wheel and the track. Through this structural design, the lubricating oil can cover the entire contact surface more efficiently, enhance the lubrication effect, and also help to remove impurities, further improving the wear resistance of the running wheel.

[0016] 2. In the traveling device of the crane trolley, intermittent refueling control is realized. The intermittent working mode of the refueling component is realized through the design of the reduction gear and the elastic telescopic lever. This design ensures that the lubricating oil is sprayed only in the required time period, which not only ensures sufficient lubrication effect, but also avoids waste and potential safety hazards caused by excessive lubricating oil. In this way, the running wheel can always maintain a proper lubrication state during operation, reducing unnecessary friction loss.

[0017] 3. In the traveling device of the crane trolley, lubrication protection is realized during starting and braking. Through the cooperation of the pneumatic component and the powder spraying component, lubricating powder (such as graphite powder and molybdenum disulfide powder) is sprayed to the bottom of the running wheel during the starting and braking stages of the crane to reduce the slipping phenomenon during starting and braking. This instant lubrication mechanism can significantly reduce the wear on the running wheel surface, especially under high-load operating conditions, further extending the service life of the running wheel.

[0018] 4. In this crane trolley travel device, track impurities cleaning and wear prevention are achieved. By setting up an air blowing component, the device can continuously clean the track surface during the crane travel process to prevent the accumulation of impurities. Specifically, the nozzle blows air toward the track surface and the tangential position of the running wheel, effectively removing impurities on the track and preventing these impurities from causing additional wear under the rolling of the running wheel. This not only reduces the wear of the running wheel, but also reduces the risk of derailment caused by uneven tracks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Existing track impurities cause uneven wear of the crane wheels and potential derailment risks. In addition, brake slippage aggravates wear. Measures need to be taken to reduce wear and extend the life of the wheels.

[0023] To this end, the present invention provides a crane trolley travel device, see Figure 1-Figure 3 As shown, it includes a track body 1 and a crane body arranged on the track body 1 through mounting frames 2 on both sides, driving devices 3 are respectively arranged at the front and rear ends of the mounting frame 2, and a wheel body 4 is arranged at the output end of the driving device 3 located in the mounting frame 2. The crane body drives the corresponding wheel body 4 to rotate through four driving devices 3, thereby driving the crane body to travel on the track body 1.

[0024] For details, see Figure 4-Figure 5 As shown, a pneumatic assembly 5 corresponding to the walking wheel body 4 is provided in the mounting frame 2, and the pneumatic assembly 5 includes an air pump 51 fixed in the mounting frame 2, and the output end of the air pump 51 is connected to a four-way pipe 52, and the other three ports of the four-way pipe 52 are respectively a first joint 53, a second joint 54 and a third joint 55.

[0025] Further, such as Figure 5As shown, the first joint 53, the second joint 54 and the third joint 55 are respectively provided with a refueling assembly 6, an air blowing assembly 7 and a powder spraying assembly 8. Secondly, when the running wheel body 4 is braked, the air pump 51 stops working with a hysteresis, that is, when the running wheel body 4 is braked, the stopping of the air pump 51 will have a hysteresis, but the hysteresis time is not long, and it only needs to meet the power demand of the powder spraying assembly 8 for spraying powder on the bottom of the running wheel body 4 below; When the wheel body 4 starts and brakes, due to the large size of the crane body itself and the load, slipping may occur during starting and braking. In order to reduce the wear on the surface of the wheel body 4 caused by slipping, a powder spraying assembly 8 is required to spray lubricating powder near the bottom where the wheel body 4 contacts the track body 1 during the starting and braking stages of the wheel body 4. The lubricating powder can be graphite powder, molybdenum disulfide powder, etc.

[0026] It is worth mentioning that although lubricating powder is sprayed on the bottom of the running wheel body 4 during the starting and braking stages of the running wheel body 4, the effect on the running and braking of the running wheel body 4 is negligible due to the weight of the crane body and the load, and the lubricating powder is only used to reduce wear. Among them, Figure 5 and Figure 16-Figure 19As shown, the powder spraying assembly 8 includes a second control assembly 82 and powder spraying heads symmetrically arranged at both ends of the bottom of the walking wheel body 4, the powder spraying heads point to the bottom of the end of the walking wheel body 4 that contacts the surface of the track body 1, and the second control assembly 82 controls the pneumatic assembly 5 through electromagnetic technology to communicate with the powder spraying head and spray lubricating powder when the walking wheel body 4 is braked; the powder spraying assembly 8 also includes a third output pipe 81, one end of the third output pipe 81 is connected to the third joint 55, and the other end of the third output pipe 81 is connected to the second control assembly 82, and the third output pipe 81 is connected to the powder storage box 83 through the second control assembly 82. A connecting pipe 84 is provided on the side of the powder storage box 83 away from the second control assembly 82, and the powder storage box 83 is respectively connected to the first powder blowing pipe 85 and the second powder blowing pipe 86 through the connecting pipe 84, and the ends of the first powder blowing pipe 85 and the second powder blowing pipe 86 away from the connecting pipe 84 are respectively connected to the powder spraying heads located on both sides of the bottom of the walking wheel body 4 Connection; the second control component 82 includes a transfer tube 821, in which a blocking tube 823 adapted to the inner wall of the transfer tube 821 is slidably arranged, and the transfer tube 821 is divided into a first chamber 827 and a second chamber 828 by the blocking tube 823, the first chamber 827 is connected with the powder storage box 83, and the end of the second chamber 828 away from the first chamber 827 is in a sealed setting, and an air inlet hole 822 connected with the third output pipe 81 is opened at the top of the transfer tube 821, and a tension spring 824 is arranged in the second chamber 828, one end of the tension spring 824 is fixedly connected to the blocking tube 823, and the other end of the tension spring 824 is fixedly connected to the end of the transfer tube 821 away from the powder storage box 83, a first electromagnetic block 825 is arranged on the inner wall of the end of the transfer tube 821 away from the powder storage box 83, and a second electromagnetic block 826 magnetically repelling the first electromagnetic block 825 is arranged at the end of the blocking tube 823 away from the powder storage box 83.

[0027] Specifically, see Fig.18 and Fig.19 As shown, in the initial state, the third output pipe 81 is connected to the first chamber 827 through the air inlet hole 822, and the blocking pipe 823 is located on the side of the air inlet hole 822 away from the powder storage box 83; When the running wheel body 4 is in working state, the first electromagnetic block 825 and the second electromagnetic block 826 are started, and the blocking tube 823 is pushed to the bottom of the air inlet 822 by the magnetic repulsion of the first electromagnetic block 825 and the second electromagnetic block 826, and the air inlet 822 is blocked. Before the first electromagnetic block 825 and the second electromagnetic block 826 are started, the air pump 51 is started first, so at this moment the third output pipe 81 is connected to the first chamber 827 through the air inlet 822, so at the moment of starting, lubricating powder can be sprayed to both ends of the bottom of the running wheel body 4 first, so as to reduce the wear caused by the starting slip of the running wheel body 4, and because the wear caused by the starting slip is less than that caused by the braking slip, the spraying amount at this moment can meet the demand for protecting the running wheel body 4, and there is no need to require a larger amount of lubricating powder in the braking stage; When the wheel body 4 is in braking state, the first electromagnetic block 825 and the second electromagnetic block 826 are closed synchronously, and the blocking tube 823 is reset by the tension of the tension spring 824, so that the blocking tube 823 is located on the side of the air inlet 822 away from the powder storage box 83, and the third output pipe 81 is connected with the first chamber 827 through the air inlet 822. Then, combined with the hysteresis of closing the air pump 51 mentioned above, at this stage, the powder storage box 83 obtains power to spray the lubricating powder to the bottom of the wheel body 4, thereby reducing the wear of the wheel body 4 caused by slipping during the braking stage.

[0028] Furthermore, a speed reduction assembly 15 for intermittently controlling the oiling assembly 6 to communicate with the pneumatic assembly 5 is also provided on the output end of the driving device 3; Among them, see Figure 5 and Fig.11 As shown, the reduction assembly 15 includes a driving gear 151 fixedly mounted on the output end of the driving device 3, and a reduction gear 152 is meshed on one side of the driving gear 151. The reduction gear 152 is rotatably connected to the inner wall of the mounting frame 2, and an elastic telescopic blocking rod 153 is fixedly mounted on the side of the reduction gear 152 adjacent to the walking wheel body 4. The reduction gear 152 and the driving gear 151 are arranged to slow down the rotation speed of the reduction gear 152, thereby meeting the subsequent elastic telescopic blocking rod 153 to control the refueling assembly 6 to intermittently spray oil to the walking wheel body 4, thereby preventing excessive lubricating oil from being sprayed on the track body 1 and the walking wheel body 4, causing waste.

[0029] For details, see Figure 5 , Figure 6 and Fig.11 As shown, a plurality of refueling pipes 12 are circumferentially opened in the running wheel body 4 around the center of the circle, and the refueling assembly 6 intermittently sprays lubricating oil to the contact surface between the running wheel body 4 and the track body 1 through the refueling pipes 12; and the refueling assembly 6 includes a first output pipe 61 and an oil storage tank 63, the oil storage tank 63 is fixedly arranged in the mounting frame 2, and the oil storage tank 63 is rotatably connected to the output end of the driving device 3, one end of the first output pipe 61 is communicated with the first joint 53, and the other end of the first output pipe 61 is communicated with the oil storage tank 63, and a first control assembly 62 controlled by an elastic telescopic blocking rod 153 is arranged in the first output pipe 61; Among them, Figure 12-14 As shown, the first control assembly 62 includes a blocking disk 621 rotatably disposed in the first output tube 61, the structure of the blocking disk 621 is adapted to the inner wall of the first output tube 61, a connecting rod 622 is disposed at the top of the blocking disk 621, one end of the connecting rod 622 is fixedly connected to the blocking disk 621, the other end of the connecting rod 622 extends to the outside of the first output tube 61 and is fixedly connected to a control rod 623, and a mounting box 624 is fixedly disposed at the bottom of the control rod 623; secondly, the control rod 623 is a U-shaped structure, and a torsion spring 625 is disposed in the mounting box 624 to always keep the horizontal end of the U-shaped structure of the control rod 623 perpendicular to the axial trend of the first output tube 61; as shown in FIG. Fig.14 As shown, when the elastic telescopic baffle rod 153 rotates to the top of its circular trajectory, the elastic telescopic baffle rod 153 contacts the longitudinal end of the U-shaped structure of the control rod 623 away from the installation box 624. When the reduction gear 152 drives the elastic telescopic baffle rod 153 to rotate to a certain position, the elastic telescopic baffle rod 153 will be out of contact with the control rod 623 due to its length and the elastic telescopic characteristics of the elastic telescopic baffle rod 153, causing the control rod 623 to reset under the action of the installation box 624. In this process, the blocking plate 621 is driven to rotate, causing the first joint 53 to be connected to the oil storage tank 63 through the first output pipe 61, so that the lubricating oil in the first output pipe 61 is powered to blow it toward the refueling pipe 12 and spray it onto the surface of the walking wheel body 4.

[0030] For further information, see Figure 6-Figure 10 As shown, in order to spray oil toward the surface where the wheel body 4 contacts the track body 1 to reduce wear, a refueling groove 11 is provided on one side of the wheel body 4 located at the oil storage tank 63. The wheel body 4 is connected to one side of the oil storage tank 63 through the refueling groove 11. One end of a refueling pipe 12 is connected to the refueling groove 11, and the other end of the refueling pipe 12 extends to the outside of the middle position of the surface where the wheel body 4 contacts the track body 1. Secondly, a first drainage groove 13 with a circular structure is provided along the middle position of the outer periphery of the surface where the wheel body 4 contacts the track body 1. One end of the refueling pipe 12 away from the refueling groove 11 is located in the first drainage groove 13. A plurality of second drainage grooves 14 along the axial direction of the wheel body 4 are arranged circumferentially on the periphery of the surface where the wheel body 4 contacts the track body 1, and one end of the refueling pipe 12 located in the first drainage groove 13 is located in the middle position of the second drainage groove 14. By setting the first drainage groove 13 and the second drainage groove 14, the lubricating oil sprayed from the refueling pipe 12 can flow to the surface of the wheel body 4 more evenly. It should be added that when the first drainage groove 13 and the second drainage groove 14 are opened and some impurities or lubricating powder enter, the presence of the nozzle 74 blowing tangentially will clean this position.

[0031] For further information, see Figure 5 and Fig.15 As shown, in addition to reducing the wear of the running wheel body 4 on the track body 1, the track body 1 needs to be cleaned to prevent foreign objects from falling on the track body 1 and causing wear on the running wheel body 4. The blowing assembly 7 includes a second output pipe 71, one end of the second output pipe 71 is connected to the second joint 54, the other end of the second output pipe 71 extends to the top position of the running wheel body 4 and the two sides are symmetrically connected with the first blowing pipe 72 and the second blowing pipe 73, respectively. The first blowing pipe 72 and the second blowing pipe 73 are connected with a nozzle 74 at one end away from the second output pipe 71, and the nozzles 74 are symmetrically arranged on both sides of the top of the running wheel body 4, and the nozzles 74 point to the surface of the track body 1 and the tangential position of one side of the running wheel body 4.

[0032] It should be added that Figure 4 and Fig.15 As shown, in order to ensure that the nozzles 74 can blow to a larger range on the surface of the track body 1 on both sides of the walking wheel body 4, a first blowing port 9 and a second blowing port 10 are respectively opened on both sides of the walking wheel body 4 in the mounting frame 2. The opening positions of the first blowing port 9 and the second blowing port 10 are respectively adapted to the wind direction of the nozzles 74 on both sides of the walking wheel body 4. In this way, when the walking wheel body 4 moves forward or backward, impurities on the track body 1 on both sides can be blown away by the nozzles 74 to prevent them from being crushed by the walking wheel body 4 and causing wear of the walking wheel body 4. Moreover, since the nozzles 74 are tangential to the two sides of the walking wheel body 4, the remaining wind can also blow the lubricating oil on the surface of the walking wheel body 4, so that the lubricating oil on the surface of the walking wheel body 4 is accelerated to flow on the first drainage groove 13 and the second drainage groove 14, thereby increasing the coating efficiency of the lubricating oil on the surface of the walking wheel body 4 and causing it to slide to the bottom of the walking wheel body 4 as soon as possible, so that when the walking wheel body 4 is running, there is enough lubricating oil on the surface in contact with the track body 1.

[0033] In summary, during the start / braking phase: the air pump 51 starts → the powder spraying component 8 sprays lubricating powder first → the magnetic component 825 / 826 intervenes to cut off the powder spraying → the air blowing component 7 starts cleaning synchronously; during the uniform speed driving phase: the reduction gear 152 triggers the refueling component 6 to spray oil intermittently → the drainage groove 13 / 14 guides the oil film to be evenly distributed → the tangential airflow of the nozzle 74 assists the oil film to diffuse; during the braking lag phase: the air pump 51 is closed with a delay → the powder spraying component 8 replenishes powder for the second time → the braking slip energy is offset; thereby effectively solving the problem of uneven wear of the crane running wheels and potential derailment risks caused by existing track impurities, and the aggravation of wear due to brake slippage, and measures need to be taken to reduce wear and extend the life of the running wheels.

[0034] Working principle: During specific operation, the driving device 3 is started, driving the wheel body 4, and then driving the crane body to move on the track body 1. During the starting process of the driving device 3, the air pump 51 is started synchronously, but the first electromagnetic block 825 and the second electromagnetic block 826 are started with a lag. In this way, the air pump 51 is started, and the third output pipe 81 is connected with the powder storage box 83. When the wheel body 4 is started, a certain amount of lubricating powder is first sprayed toward both ends of the bottom of the wheel body 4 to prevent slipping and wear during starting. After the first electromagnetic block 825 and the second electromagnetic block 826 are started, the blocking tube 823 is pushed to the bottom of the air inlet 822 by the repulsive force, blocking the connection between the third output pipe 81 and the powder storage box 83. Therefore, when the walking wheel body 4 is running, the powder storage box 83 no longer sprays powder through the powder spraying head.

[0035] After the air pump 51 is started, the nozzles 74 on both sides of the wheel body 4 are always connected through the second output pipe 71, spraying toward the two sides of the wheel body 4 and the surface of the track body 1 located on both sides of the wheel body 4, and blowing the lubricating oil and impurities on the surface of the track body 1 and the surface of the wheel body 4 where the wheel body 4 is to run.

[0036] After the wheel body 4 travels a certain distance, the reduction gear 152 driven by the driving gear 151 rotates until the elastic telescopic blocking rod 153 can touch the control rod 623, thereby causing the blocking plate 621 to rotate, and the first joint 53 is connected to the oil storage tank 63 through the first output pipe 61. The oil storage tank 63 obtains power and sprays the lubricating oil therein to the surface of the wheel body 4 through the refueling pipe 12, and then flows to the surface of the wheel body 4 with the help of the wind force of the first drainage groove 13, the second drainage groove 14 and the nozzle 74, so that the wheel body 4 has lubricating oil to reduce wear during movement, and at the same time, it will not be coated with a large amount of lubricating oil.
