Description

Technical Field

[0001] The utility model belongs to the technical field of sintered wheels, in particular to a sintered trolley wheel. Background Art

[0002] In the current refueling process, the sintering trolley needs to be stopped and then the wheels of the sintering trolley need to be refueled manually using a refueling gun. This has the problems of poor construction site environment, low refueling efficiency, and difficulty in controlling the refueling amount. Therefore, the good lubrication of the sintering trolley wheel bearings cannot be guaranteed, resulting in aggravated axle wear and even wheel locking, which leads to frequent wheel replacement, which is costly and laborious.

[0003] At present, there are also automatic oilers for sintering trolleys being developed in the market, using mechanical positioning and visual positioning methods, such as patents CN113864627A and CN110822908A. Both types of automatic oiling require precise positioning, and the oil gun and oil nozzle must be aligned during movement. This positioning process is technically difficult and it is easy to have inaccurate positioning problems, which will lead to oiling failure. The highest oiling success rate is about 90%. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide a sintering trolley wheel to effectively ensure accurate oiling.

[0005] The sintering trolley wheel comprises a trolley wheel body, an oil injection mechanism for oil injection is installed at the oil nozzle of the trolley wheel body, the oil injection mechanism comprises an outer cylinder, one end of the outer cylinder is provided with an oil injection channel for injecting oil into the oil nozzle, and an oil injection switch and an installation area are sequentially arranged from the oil injection channel to the inner part of the outer cylinder;

[0006] An oil pump and a battery for providing power to the oil pump are installed in the installation area. An oil delivery channel is provided in the outer cylinder between the oil outlet end of the oil pump and the oil filling switch. The oil delivery channel seals and connects the oil outlet end with the oil filling switch. A grease cylinder is provided at the oil inlet end of the corresponding oil pump.

[0007] Furthermore, the oil filling switch includes a cavity arranged in the outer tube, a blocking bead is arranged in the cavity to block the oil outlet of the oil delivery channel, a spring is installed in the cavity to block the blocking bead at the oil outlet of the oil delivery channel, and the cavity is communicated with the refueling channel.

[0008] Furthermore, the grease cylinder is installed outside the outer cylinder, and the grease cylinder is connected to the oil inlet end of the oil pump through a pipeline.

[0009] Furthermore, a pressure gauge and a pressure regulating valve are installed at the oil outlet of the oil pump.

[0010] Furthermore, the outer cylinder is mounted on the trolley wheel body through fasteners.

[0011] Furthermore, a control unit is installed in the installation area, and the control unit is used to start and stop the oil pump at a scheduled time.

[0012] Furthermore, the outer cylinder has a heat insulation function.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model directly skips the existing positioning link of automatic oiling of sintering trolley wheels. The utility model is equivalent to installing an oiler on each sintering trolley wheel. As long as the oiling channel is aligned with the oil receiving nozzle of the trolley wheel body, the entire oiler moves with the sintering trolley wheel, which is very convenient to use.

[0018] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Example

[0021] A sintering trolley wheel described in this embodiment, such as Figure 1As shown, it comprises a trolley wheel body 1, an oil filling mechanism for filling oil is installed at the oil receiving nozzle of the trolley wheel body 1, and the oil filling mechanism comprises an outer cylinder 8, one end of the outer cylinder 8 is provided with a filling channel for filling oil to the oil receiving nozzle, and an oil filling switch 3 and a mounting area are sequentially arranged from the filling channel to the outer cylinder 8;

[0022] An oil pump 5 and a battery 6 for providing power to the oil pump 5 are installed in the installation area (the battery 6 and the oil pump 5 are electrically connected, and the connection method is well known and will not be described here). An oil delivery channel 11 is arranged in the outer tube 8 between the oil outlet end of the oil pump 5 and the oil filling switch 3. The oil delivery channel 11 seals and connects the oil outlet end with the oil filling switch 3, and a grease cylinder 4 is arranged at the oil inlet end of the corresponding oil pump 5.

[0023] The oil filling switch 3 of this embodiment includes a cavity arranged in the outer tube 8, in which a blocking bead 12 is arranged to block the oil outlet of the oil delivery channel 11, and a spring 13 is installed in the cavity to block the blocking bead 12 at the oil outlet of the oil delivery channel 11, and the cavity is connected to the refueling channel. When applied, other existing structures of the oil filling switch 3 can also be used. When the oil filling switch 3 designed in this section is working, when the oil pump 5 is working, oil will be delivered to the oil delivery channel 11, and at this time, the oil will overcome the elastic force of the spring 13 to push the blocking bead 12 outward (that is, Figure 1 When the plugging bead 12 leaves the oil outlet of the oil delivery channel 11, the oil will enter the cavity and finally refuel the oil receiving nozzle of the trolley body 1 through the refueling channel; when the oil pump 5 is not working, the oil outlet of the oil delivery channel 11 will continue to be blocked under the elastic force of the spring 13. The installation method of the spring 13 can be Figure 1 In the manner shown in the figure, one end of the spring 13 is fixed on the blocking bead 12, and the other end is pressed against the inner wall of the cavity; when used, a conical spring of the spring 13 is preferably used. The installation method of the spring 13 can also be that one end of the spring 13 is fixed on the blocking bead 12, and the other end is directly fixed on the cavity. Of course, other installation methods can also be used as long as they can meet the requirements.

[0024] In order to facilitate regular replacement of oil, the grease cylinder 4 is installed outside the outer cylinder 8, and the grease cylinder 4 is connected to the oil inlet end of the oil pump 5 through a pipeline. When used, the grease cylinder 4 can also be installed in the installation area, because the amount of oil required for the trolley wheel body 1 each time is not much, and with the grease cylinder 4 of this design, it can be safely ensured that it is replaced once a month or several months.

[0025] In order to facilitate observation of the refueling status at any time, a pressure gauge 9 and a pressure regulating valve 10 are installed at the oil outlet end of the oil pump 5.

[0026] Considering the large size difference between the trolley wheel body 1 and the outer cylinder 8, the outer cylinder 8 is mounted on the trolley wheel body 1 through a fastener 2, and the fastener 2 is a flange. The flange is first mounted on the trolley wheel body 1, and then the outer cylinder 8 is mounted on the flange. The refueling passage is connected to the oil receiving nozzle of the trolley wheel body 1 through a pipeline; when used, a connecting plate can also be added to the outer cylinder 8 as the fastener 2, and the connecting plate is fixed to the trolley wheel body 1.

[0027] In order to further realize automatic control, a control unit 7 is installed in the installation area. The control unit 7 is used to start and stop the oil pump 5 at a scheduled time. Timed refueling can be realized by the control unit 7, because the oil consumption of the trolley wheel body 1 during operation is basically a value with a small change (according to production experience, the single oil injection volume is 3-5mL, the oil pump pressure is set in advance to be above 2MPa, the oil injection time is set to 3-5S, and the oil injection time interval is 10-20 days.), which can be realized by this timed control unit 7. If the oil consumption of the trolley wheel body 1 changes greatly at that time, it is necessary to add an induction switch at the oil nozzle of the trolley wheel body 1 to sense whether the refueling of the trolley wheel body 1 is completed. This can be seen in the automatic refueling gun jump technology in the automotive field.

[0028] Considering that the trolley wheel body 1 works in a high temperature environment, the outer cylinder 8 has a heat insulation function. When used, a layer of heat insulation material can be set inside and / or outside the outer cylinder 8, or the outer cylinder 8 can be directly made of heat insulation material.
