Description

Technical Field

[0001] The invention belongs to the technical field of sintering trolley, and particularly relates to an automatic docking oil injection system for the wheels of a sintering trolley. Background Art

[0002] The sintering trolley is the main equipment in the sintering production operation of a steel plant. During the production process, the sintering locomotive needs to run continuously without interruption, which inevitably causes failures of the wheels of the sintering trolley due to being in a harsh working environment of high temperature and high dust for a long time. In order to ensure the normal operation of the sintering trolley, it is necessary to regularly inject oil into the wheels of the sintering trolley during the sintering operation to ensure that the wheels of the sintering trolley can also operate normally under harsh working conditions such as high temperature, heavy load, and dust.

[0003] At present, the lubrication of most sintering trolley wheels adopts the methods of manual oil injection, follower positioning with a stop bar, and real-time tracking oil injection by an industrial manipulator. However, the oil injection equipment has a high failure rate under harsh working conditions and is difficult to repair when problems occur. Moreover, due to problems such as wear during the manufacturing, installation, and operation of the sintering trolley wheels, the oil cups for injecting lubricating oil at the ends of the wheels cannot always be guaranteed to be in the central position, which brings difficulties to the positioning of the oil cups, affects the oil injection efficiency, and even causes oil spillage, polluting the wheels of the sintering trolley and resulting in waste of oil fluid.

In addition, the meanings of "multiple" and "several" are two or more, unless otherwise clearly specifically defined.

[0056] Please refer to Figures 1 to 9, the automatic docking and oil injection system for the sintering trolley wheels provided by the present invention will be described. The automatic docking and oil injection system for the sintering trolley wheels includes a base plate 1, a plurality of positioning arms 2, and an oil injection assembly 3. An installation hole 11 is provided at the center of the base plate 1, and a plurality of guide rails 12 are arranged radially on the plate surface of the base plate 1 facing the wheels with the installation hole 11 as the center; the plurality of positioning arms 2 correspond to the guide rails 12 one by one and are slidably arranged on the guide rails 12 along the extension direction of the guide rails 12. The central axis of the positioning arm 2 is parallel to the central axis of the installation hole 11, and the distance from the central axis of each positioning arm 2 to the installation hole 11 is the same. The three positioning arms 2 enclose a positioning space for positioning the wheels; the oil injection assembly 3 includes an oil injection pipe 31. The central axis of the oil injection pipe 31 is parallel to the central axis of the installation hole 11, and the oil injection pipe 31 passes through the installation hole 11. An oil injection head 32 is provided on the side of the oil injection pipe 31 facing the wheels; the three positioning arms 2 have a positioning state of simultaneously abutting against the outer periphery of the wheels. In the positioning state, the central axis of the positioning space, the central axis of the oil injection pipe 31, and the center of the wheels overlap.

[0057] It should be noted that the base plate 1 is vertically arranged.

[0058] It should be noted that the plurality of positioning arms 2 are all located on the ring of the same circle. In the positioning state, the axis of the formed positioning space and the central axis of the wheels overlap.

[0059] It should be noted that in the positioning state, the size of the positioning space is the same as that of the wheels.

[0060] As a specific implementation manner of the positioning arm 2, refer to Figure 1 , three positioning arms 2 are provided. The three positioning arms 2 are evenly distributed on the plate surface of the base plate 1, and the axes of the three positioning arms 2 are located on the ring of the same circle. After the wheels are installed in the positioning space, adjust the three positioning arms 2 to abut against the outer periphery of the wheels respectively. After the three positioning arms 2 all abut against the wheels, the center of the circle formed by the three positioning arms 2 and the wheel center are on the same straight line, realizing the alignment of the wheel center and the oil injection pipe 31.

[0061] Compared with the prior art, the automatic docking oil injection system for the sintering trolley wheel provided in this embodiment is provided with a plurality of positioning arms 2 on the substrate 1. When the wheel enters the positioning space, the plurality of positioning arms 2 are adjusted to abut against the outer periphery of the wheel, so that the wheel center is always on the same straight line as the center of the positioning space, and the central axis of the oil injection pipe 31 overlaps with the central axis of the positioning space, so that the oil injection head 32 can always be aligned with the oil injection hole of the wheel, ensuring the normal progress of the oil injection work. The alignment of the wheel center and the central axis of the oil injection pipe 31 is rapid, improving the oil injection efficiency; the oil injection head 32 can always be aligned with the oil injection hole of the wheel, and the oil will not leak, ensuring the cleanliness of the wheel, avoiding oil pollution, saving the labor intensity of workers, not causing oil waste, avoiding failures caused by oil leakage, and improving the safety of the oil injection work.

[0062] In some embodiments, referring to Figure 1 and Figure 5 , the positioning arm 2 includes a positioning body 21 and a slider 22. The central axis of the positioning body 21 is parallel to the central axis of the mounting hole 11; the slider 22 is provided on the side of the positioning body 21 close to the substrate 1 and is slidably matched with the guide rail 12. The length direction of the positioning body 21 is perpendicular to the plate surface of the substrate 1, and the abutting angles of the plurality of positioning bodies 21 with the wheel are the same, ensuring that the central axis of the wheel clamped by the positioning body 21 overlaps with the central axis of the mounting hole 11, facilitating the alignment of the central axis of the oil injection head 32 and the oil nozzle on the wheel, and improving the quality of the oil injection work. The slider 22 can slide along the guide rail 12, facilitating the positioning arm 2 to approach or move away from the central mounting hole 11, so as to adapt to the oil injection of wheels of different sizes, improving the adaptability of the automatic docking oil injection system for the sintering trolley wheel and increasing the scope of use.

[0063] In some embodiments, referring to Figure 8 , the guide rail 12 is provided with a chute 121 along its own length direction, and the slider 22 is slidably matched with the chute 121. The cooperation between the chute 121 and the slider 22 can limit the slider 22, so that the slider 22 can only move along the length direction of the guide rail 12, avoiding the slider 22 from deviating from the long axis direction of the guide rail 12, ensuring that when the positioning arm 2 abuts against the tire, the central axes of the plurality of positioning arms 2 all fall on the same circle, ensuring the alignment of the central axis of the oil injection pipe 31 and the oil nozzle of the wheel, improving the docking accuracy of the central axis of the oil injection pipe 31 and the oil nozzle of the wheel, and improving the docking efficiency of the central axis of the oil injection pipe 31 and the oil nozzle of the wheel.

[0064] In some embodiments, referring to Figure 8, on both sides of the sliding groove 121, limiting grooves 122 are respectively extended and formed. A limiting protrusion 221 is connected to the side surface of the sliding block 22, and the limiting protrusion 221 is in sliding fit with the limiting groove 122. During specific implementation, the limiting groove 122 and the sliding groove 121 form a convex-shaped space, and the limiting protrusion 221 is in sliding clamping connection with the limiting groove 122, so that the positioning arm 2 will not fall off the substrate 1. The limiting protrusion 221 and the limiting groove 122 can improve the limiting effect of the sliding groove 121 on the sliding block 22, so that the sliding block 22 can only move closer to or away from the center of the mounting hole 11, improving the precise control of the moving direction of the positioning arm 2.

[0065] In some embodiments, referring to Figure 1 and Figure 4 , a plurality of limiting plates 13 are respectively provided on the substrate 1 corresponding to the plurality of guide rails 12. The plate surface of the limiting plate 13 is perpendicular to the extending direction towards the guide rail 12. An elastic pushing member 4 is provided between the sliding block 22 and the limiting plate 13, and the elastic pushing member 4 is configured with a pre-tightening force for moving the sliding block 22 in a direction away from the limiting plate 13.

[0066] It should be noted that in the idle state, under the action of the corresponding elastic pushing members 4, the diameter of the circle formed by the plurality of sliding blocks 22 is greater than the diameter of the wheel to be oiled, ensuring that the wheel can enter the positioning space.

[0067] The limiting plate 13 provided in this embodiment can serve as the base of the elastic pushing member 4. When the positioning arm 2 moves close to the mounting hole 11, the elastic pushing member 4 is compressed. It is configured with a pre-tightening force for moving the sliding block 22 in a direction away from the limiting plate 13. When the positioning arm 2 finishes working, the elastic pushing member 4 resumes its original state, driving the sliding block 22 to move in a direction away from the mounting hole 11, completing the automatic reset of the positioning arm 2.

[0068] Optionally, the elastic pushing member 4 is a helical spring. The helical spring has high tensile strength and good deformation continuity, meeting the requirements for being an elastic pushing member 4. Of course, the elastic pushing member 4 can also be other elastic components, such as a high-temperature resistant rubber sleeve, as long as it can drive the sliding block 22 to automatically reset, which will not be listed one by one here.

[0069] In some embodiments, referring to Figure 1 and Figure 5 , a supporting wheel 5 is provided at the end of the positioning arm 2 away from the substrate 1. The supporting wheel 5 includes a supporting main body 51, a contact sleeve 52, and a bearing 53. The supporting main body 51 is coaxially connected to the end of the positioning arm 2; the contact sleeve 52 is sleeved on the outer periphery of the supporting main body 51, and a positioning space is formed by enclosing between a plurality of contact sleeves 52; the bearing 53 is provided between the supporting main body 51 and the contact sleeve 52, and the bearing 53 is coaxially arranged with the supporting main body 51.

[0070] It should be noted that the supporting main body 51 and the positioning main body 21 are integrally formed.

[0071] It should be noted that when the positioning arm 2 is fixed to the wheel, the outer periphery of the abutting sleeve 52 abuts against the outer periphery of the wheel.

[0072] The structure of the supporting wheel 5 provided in this embodiment is simple. The abutting sleeve 52 can rotate around the central axis of the supporting body 51. After the wheel is installed in the positioning space, the outer periphery of the wheel and the abutting sleeve 52 are in rolling fit, which minimizes friction, reduces damage to the tire and the outer periphery of the abutting sleeve 52, and extends the service life of the abutting sleeve 52.

[0073] In some embodiments, referring to Figure 1 and Figure 4 , a conical guide sleeve 23 is sleeved on one end of the positioning arm 2 close to the substrate 1. The large end of the conical guide sleeve 23 faces the substrate 1. The automatic docking oil injection system for the sintering trolley wheel further includes a distance adjusting component 6 for adjusting the size of the positioning space. The distance adjusting component 6 includes a distance adjusting plate 61 and a traction component 62. The distance adjusting plate 61 is arranged parallel to the plate surface of the substrate 1. The distance adjusting plate 61 is provided with avoidance grooves 611 corresponding to the conical guide sleeves 23 one by one. The groove walls of the plurality of avoidance grooves 611 abut against the outer periphery of the corresponding conical guide sleeve 23; the traction component 62 has a telescopic end that expands and contracts along the central axis of the substrate 1. The substrate 1 is provided with a through hole 14 corresponding to the telescopic end. The telescopic end passes through the through hole 14 and is connected to the distance adjusting plate 61 to drive the distance adjusting plate 61 to approach or move away from the substrate 1.

[0074] It should be noted that the central axis of the distance adjusting plate 61 always overlaps with the central axis of the oil injection pipe 31.

[0075] The structure of the distance adjusting component 6 provided in this embodiment is simple. When the telescopic end contracts, the distance adjusting plate 61 moves closer to the substrate 1. The groove wall of the avoidance groove 611 squeezes the conical guide sleeve 23. The conical guide sleeve 23 drives the slider 22 to move under the extrusion of the guide block 612. The slider 22 moves towards the mounting hole 11, thereby driving the positioning arm 2 to move, realizing the contraction of the positioning space until all the positioning arms 2 abut against the outer periphery of the wheel. The telescopic end drives the distance adjusting plate 61 to approach or move away from the substrate 1, thereby realizing the movement of the positioning arm 2 towards or away from the mounting hole 11. The cooperation between the traction component 62 and the distance adjusting plate 61 is simple and convenient to use.

[0076] It should be noted that when the wheel enters the positioning space and there is a misalignment between the center of the wheel and the central axis of the distance adjusting plate 61, the distance adjusting plate 61 moves closer to the base plate 1, and the positioning arms 2 move towards the wheel respectively. When the positioning arm 2 closest to the wheel abuts against the outer periphery of the wheel, this positioning arm 2 remains stationary relative to the base plate 1. Since the other positioning arms 2 do not abut against the outer periphery of the wheel, the distance adjusting plate 61 needs to continue to move closer to the base plate 1. Since one of the positioning arms 2 is stationary, during the process of the distance adjusting plate 61 moving closer to the base plate 1, it will also deviate along the inclined surface of the tapered guide sleeve 23 of the stationary positioning arm 2 until the remaining positioning arms 2 abut against the outer periphery of the wheel. At this time, the central axis of the distance adjusting plate 61 coincides with the central axis of the wheel. Since the central axis of the oil injection pipe 31 always coincides with the central axis of the distance adjusting plate 61, therefore, the center of the oil injection pipe 31 is aligned with the center of the wheel.

[0077] In some embodiments, referring to Figure 6 , the traction assembly 62 includes a traction driving member 621 and a connecting rod 622. The traction driving member 621 has an output end that expands and contracts towards the base plate 1; one end of the connecting rod 622 is hinged to the output end, and the other end is hinged to the distance adjusting plate 61. One end of the connecting rod 622 facing the positioning arm 2 forms a telescopic end. The output end of the traction driving member 621 drives the connecting rod 622 to move. The connecting rod 622 is hinged to the distance adjusting plate 61. By moving the output end closer to or away from the base plate 1, the connecting rod 622 drives the distance adjusting plate 61 to move. There is no complex mechanical cooperation. The connecting rod 622 is hinged to the distance adjusting plate 61, which can also ensure that the distance adjusting plate 61 can move along the inclined surface of the tapered guide sleeve 23 of the positioning arm 2.

[0078] Specifically, there are three connecting rods 622, and there are 3 corresponding perforations 14. The three connecting rods 622 are evenly distributed on the distance adjusting plate 61, and the distance from each connecting rod 622 to the center of the distance adjusting plate 61 is the same.

[0079] Specifically, both ends of the traction driving member 62 are fixed on the traction support frame 627, so as to realize that the traction driving member 62 and the mounting hole 11 are coaxially arranged.

[0080] In some embodiments, referring to Figure 9 , the traction assembly 62 includes a centering cylinder 623, a push-pull rod 624, and a support frame 626. The centering cylinder 623 is arranged on the side of the base plate 1 facing away from the positioning arm 2. The centering cylinder 623 has an output shaft, and the axis of the output shaft is parallel to the central axis of the mounting hole 11; one end of the push-pull rod 624 has an external thread, and the distance adjusting plate 61 is correspondingly provided with a threaded hole. The push-pull rod 624 is in threaded cooperation with the threaded hole. The other end of the push-pull rod 624 rotates synchronously with the output shaft through a belt 625. The side of the push-pull rod 624 away from the centering cylinder 623 forms a telescopic end; the support frame 626 is rotatably connected to the push-pull rod 624.

[0081] The traction assembly 62 provided in this embodiment has a stable structural transmission. The push-pull rod 624 is fixed on the support frame 626, and the push-pull rod 624 can rotate self - sufficiently. The push-pull rod 624 rotates synchronously with the output shaft through the belt 625. The other end of the push-pull rod 624 is in screw fit with the distance - adjusting plate 61, realizing the movement of the distance - adjusting plate 61 closer to or farther away from the substrate 1. The centering cylinder 623, the push-pull rod 624 and the distance - adjusting plate 61 have a stable transmission, ensuring the position movement of the positioning arm 2.

[0082] In some embodiments, referring to Figure 8 , the oil - injection assembly 3 further includes an oil - injection cylinder 33, an oil - injection cavity 34 and an oil - injection sleeve 35. The oil - injection cavity 34 is coaxially disposed through the mounting hole 11, and the diameter of the mounting hole 11 is larger than that of the oil - injection cavity 34. The oil - injection sleeve 35 is disposed through the distance - adjusting plate 61 and is coaxially arranged with the oil - injection cavity 34. The oil - injection pipe 31 sequentially penetrates through the oil - injection sleeve 35 and the oil - injection cavity 34 and is communicated with the oil - injection cylinder 33. The oil - injection cylinder 33 can inject oil into the oil - injection pipe 31, and the oil - injection sleeve 35 protects the oil - injection pipe 31. When the wheel and the positioning arm 2 are adjusted, the oil - injection head 32 can coincide with the center of the oil nozzle of the wheel, facilitating the oil - injection operation.

[0083] It should be noted that the size of the mounting hole 11 is larger than the diameter of the oil - injection cavity 34, and the oil - injection cavity 34 can move freely within the mounting hole 11.

[0084] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
