Description

Technical Field

[0001] The invention relates to a floating device, in particular to a three-way floating device used in an automatic oiling system for a sintering trolley wheel disc. Background Art

[0002] Sintering machine is an important equipment in the pre-iron process of the steel industry, and it plays the role of producing and transporting sintered ore. The sintering trolley is the main operating component of the sintering machine. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine, receive the sintering mixed material in the upper horizontal section, and return to the head wheel after preheating, ignition, sintering, cooling, and turning the material, forming a transmission cycle to achieve the purpose of sintering the material. The wheel bearings of the sintering trolley are subjected to harsh working conditions such as high temperature, heavy load, impact vibration, dust and water flushing. If lubrication is not timely, it may cause the sintering machine to stop, which not only increases the maintenance cost of the trolley, but also increases the downtime of the sintering machine, which will cause serious losses to the entire sintering production. At present, the lubrication of most sintering trolley wheels is done by manual refueling, which is not only inefficient and labor-intensive for workers, but also requires manual online operation to add an automatic refueling system for the sintering trolley wheel disc to the sintering machine. The refueling of the trolley wheels can be automated, intelligent, and more efficient; it avoids the safety risks of manual refueling combined with human-machine, reduces labor intensity and workload, and improves work efficiency.

[0003] At present, there is also a way to use the automatic oiling system of the sintered trolley wheel disc to participate in the oiling. However, it mainly uses standard parts such as universal joints and cross guides to achieve floating alignment. It is still prone to oil leakage, and manual adjustment is still required during use, which is not very convenient.

[0004] The prior art CN2415211Y provides a sealing device, which can be used to deal with the secondary oil intrusion seal on both sides of the sintering machine body.

[0032] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] Embodiment 1

[0034] like Figures 1 to 3 The three-way floating device used in the automatic oiling system of the sintering trolley wheel disc includes a base assembly, which is different in that: an elastic adjustment assembly is sleeved on the base assembly, and a coupling flange 1 is provided at one end of the elastic adjustment assembly to compensate for the displacement of the oiling hole attached to the oiling head 3 installed later in the X-axis, Y-axis and Z-axis directions during the oiling period. At the same time, an oiling adapter plate 2 is provided on the coupling flange 1, and the oiling adapter plate 2 is provided with an oiling head 3. Specifically, the base assembly includes a base body 4, and the base body 4 is connected to a mandrel 13 through a screw 5. In addition, in order to meet the combination stability of the elastic adjustment assembly and avoid abnormal distortion or abnormal force during deformation, a cover plate 6 is provided at the top of the mandrel 13, and the cover plate 6 is located in the coupling flange 1, and an elastic adjustment assembly is sleeved on the mandrel 13. During the standby use state, the cover plate 6 is fitted with the coupling flange 1 through the pre-tightening force of the elastic adjustment assembly. Preferably, an effective elastic force can be provided by selecting a suitable elastic adjustment assembly to make the cover plate 6 and the coupling flange 1 fit tightly.

[0035] In view of a preferred embodiment of the present invention, a positioning groove is provided on the base body 4, and the front end of the elastic adjustment component is embedded in the positioning groove; a limiting groove is provided in the direction of the base body 4 by the coupling flange 1, and the rear end of the elastic adjustment component is embedded in the limiting groove. In this way, the pre-positioning of the two ends of the elastic adjustment component can be met to prevent it from loosening at one end during deformation and resetting. Of course, in order to better consolidate the effect of pre-positioning, a plurality of top screw assemblies 7 can be provided on the base body 4 and the coupling flange 1, and the top screw assemblies 7 are in contact with the elastic adjustment component to achieve limiting. In this way, even if a large deformation occurs in an extreme environment, it can be ensured that the two ends of the elastic adjustment component will not loosen. Through multiple comparative tests, the elastic adjustment component is a spring 8, which can achieve a better use effect. At the same time, in view of the configuration needs of some simple use environments, a spring plate with a wave folding structure can also be used to constitute the elastic adjustment component. Of course, other mechanisms or components that can achieve elastic deformation and resetting can also be used to replace the elastic adjustment component, which will not be repeated here.

[0036] Further, considering the convenience of oil filling during subsequent use, the oil filling adapter plate 2 is connected to the oil filling head 3 by screws 5, and the oil filling head 3 is provided with a transmission path that is connected to the oil filling adapter plate 2. At the same time, a leak-proof top screw 9 is provided in the transmission path. In this way, oil leakage can be effectively prevented during oil filling. In addition, the present invention also provides a grease channel 10 on the transmission path, and the grease channel 10 is located at the front end of the leak-proof top screw 9. In this way, grease can be effectively output during use to avoid improper blockage.

[0037] In combination with actual implementation, a plurality of anti-loosening screws 11 are provided in the base body 4, and the anti-loosening screws 11 are in contact with the core shaft 13. In this way, even if the core shaft 13 is impacted during the resetting of the elastic adjustment component, the combination stability of the core shaft 13 itself can be ensured to avoid unnecessary loosening.

[0038] Further, the core shaft 13 is connected to the cover plate 6 by means of the screw 5, and the cover plate 6 is provided with a contact screw 12, which is in contact with the screw 5. Thus, an effective anti-loosening locking combination can be achieved.

[0039] During implementation, considering the convenience of oil injection docking, the front end of the oil injection head 3 is provided with a docking mechanism, which is an external threaded sleeve; or, the docking mechanism is an internal threaded sleeve. This adapts to the type of threaded joint at the front end of the corresponding pipeline in the oil injection system, and realizes matching and stable threaded connection.

[0040] The working principle of the present invention is as follows:

[0041] After the oiling head 3 is connected to the corresponding mechanism in the oiling system, the base assembly can be connected to a robot or other motion mechanism to achieve linkage connection. During the oiling process, the force of the oiling head 3 is transmitted to the coupling flange 1. After that, the elastic adjustment component is deformed by the force. At the same time, the coupling flange 1 is separated from the cover plate 6 to compensate for the displacement of the preset oiling hole of the oiling head 3 in the X-axis, Y-axis, and Z-axis directions.

[0042] Embodiment 2

[0043] The three-way floating device used in the automatic oiling system of the sintering trolley wheel disc includes a base assembly, which is different in that: an elastic adjustment assembly is sleeved on the base assembly, and a coupling flange 1 is provided at one end of the elastic adjustment assembly to compensate for the displacement of the oiling hole attached to the oiling head 3 installed later during the oiling process in the directions of the X-axis, Y-axis, and Z-axis. At the same time, an oiling adapter plate 2 is provided on the coupling flange 1, and an oiling head 3 is provided on the oiling adapter plate 2.

[0044] Specifically, the base assembly includes a base body 4, and the base body 4 is connected to a plurality of circumferentially distributed core shafts 13 by screws 5. Each core shaft 13 is sleeved with an elastic adjustment component consisting of a spring 8. A cover plate 6 is provided at the top of the core shaft 13, and the cover plate 6 is located in the coupling flange 1. During the standby state, the cover plate 6 is fitted with the coupling flange 1 by the pre-tightening force of the elastic adjustment component. Preferably, an effective elastic force can be provided by selecting a suitable elastic adjustment component to make the cover plate 6 and the coupling flange 1 fit tightly.

[0045] In this way, multiple groups of springs 8 can be used to cope with multiple offsets in the X-axis, Y-axis and Z-axis directions caused by large impact forces, thereby achieving effective stabilization of the oiling head 3 and ensuring that its oiling hole does not have a large offset.

[0046] It can be seen from the above textual description and the accompanying drawings that the present invention has the following advantages:

[0047] 1. Through the cooperation of the base assembly and the elastic adjustment assembly, three-way compensation of the X-axis, Y-axis and Z-axis can be achieved to meet the use requirements under all working conditions and avoid faults such as nozzle breakage and robot shutdown.

[0048] 2. The elastic adjustment component can automatically reset, ensuring that the present invention can automatically return to the standby state when not in use, without manual intervention and adjustment, and is convenient to use.

[0049] 3. It adopts a purely mechanical structure configuration, without the intervention of electronic devices, has high stability in use, is not affected by oil pollution, and is also easy to clean later.

[0050] 4. The oil injection accuracy after docking is high, and there is no need for personnel to conduct on-site docking and deployment, which can meet the positive oil injection needs of the equipment under the greatest circumstances.

[0051] 5. The overall structure is simple, easy to manufacture and use.

[0052] In addition, the indicated orientations or positional relationships described in the present invention are all based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or structure referred to must have a specific orientation or be operated with a specific orientation structure. Therefore, they cannot be understood as limitations on the present invention.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
