Description

Technical Field

[0001] The utility model relates to the field of maintenance equipment, in particular to an operating vehicle used for the maintenance of mining engineering machinery. Background Art

[0002] When lubricating the lubrication points of mining engineering machinery, relevant staff are required to perform lubrication work at high altitudes, which is highly dangerous and requires the device to be shut down for operation, reducing work efficiency.

[0003] The existing maintenance equipment uses a quantitative and constant pressure intelligent filling system on the filling engineering vehicle. After the grease is output from the pneumatic grease delivery pump of the filling engineering vehicle, the accurate grease supply to each lubrication point is controlled by the PLC. When the oil pump is working, the volumetric flow meter checks the oil output in real time, and automatically stops supplying oil when the oil volume reaches the set value, avoiding over-lubrication caused by too much grease or poor lubrication of the bearing due to too little grease.

[0004] This method solves the problem of having to stop the machine and climb to a height during lubrication, which affects work efficiency. However, after lubrication, the mining machinery and the maintenance vehicle are disconnected, and the residual oil in the oil pipeline will drip onto the ground and pollute the surrounding environment. The residual oil left on the inner wall of the oil pipeline will deteriorate if not cleaned for a long time, causing contamination to the oil used for the next lubrication, affecting the normal operation of the device and reducing the working efficiency of the device. Utility Model Content

[0005] In order to solve the above technical problems or at least partially solve the above technical problems, the utility model provides a work vehicle for the maintenance of mining engineering machinery, which cooperates between a one-way sealing valve and an air compressor to blow the residual oil into a residual oil treatment chamber and treat it, effectively solving the impact caused by the residual oil in the oil pipeline after oil transportation and ensuring the normal operation and work efficiency of the device.

The air inlet pipe is connected to an air source to supply a high-pressure airflow into the resin tube.

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the scheme of the utility model will be further described below. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0027] The following description sets forth many specific details to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the implementation methods in the specification are only part of the implementation methods of the present invention, rather than all of the implementation methods.

[0028] Combination Figures 1 to 5 As shown, the working vehicle for the maintenance of mining engineering machinery provided by the embodiment of the utility model comprises a mining engineering machinery body 1 and a maintenance vehicle body 2. A lubrication point is provided at the position of the shaft of the mining engineering machinery 1, and an oil collecting block 3 is installed on the mining engineering machinery 1. One end of the oil collecting block 3 is provided with a resin tube 31 connected to the lubrication point, and the other end of the oil collecting block 3 is connected to the output pipe of the maintenance vehicle body 2. A one-way sealing valve is provided in the direction from the resin tube 31 to the lubrication point, and an air inlet pipe 311 is provided at the oil outlet end of the resin tube 31. The air inlet pipe 311 is provided with a first valve, and the output pipe of the maintenance vehicle body 2 is provided with a first valve. A residual oil delivery pipe 51 is fixedly connected, and a second valve is provided on the residual oil delivery pipe 51. A third valve is provided on the output pipe of the maintenance vehicle body 2 between the driving end of the maintenance vehicle body 2 and the residual oil delivery pipe 51. When the maintenance vehicle body 2 supplies oil to the oil collecting block 3, the first valve and the second valve are closed, and the third valve is opened. When the residual oil on the inner wall of the resin tube 31 is cleaned, the third valve is closed, and the first valve and the second valve are opened. The air inlet pipe 311 is connected to the air source to supply high-pressure airflow into the resin tube 31. The high-pressure gas entering the resin tube 31 drives the residual oil in the resin tube 31 to be discharged through the residual oil delivery pipe 51.

[0029] Therefore, the residual oil is blown into the residual oil treatment chamber and treated through the cooperation between the one-way sealing valve and the air compressor, which effectively solves the impact caused by the residual oil in the oil pipeline after oil transportation and ensures the normal operation and work efficiency of the device.

[0030] Among them, an oil pump 8 is installed in the maintenance vehicle body 2, and the oil pump 8 is the driving end of the maintenance vehicle body 2. The output end of the oil pump 8 is fixedly connected with the oil pipe 5, and the oil pipe 5 is the output pipe of the maintenance vehicle body 2. The oil pipe 5 is connected with the oil collecting block 3, and the input end of the oil pump 8 is fixedly connected with the oil extraction pipe 9, and the oil extraction pipe 9 is fixedly connected with the oil tank 10, and the oil tank 10 is located in the maintenance vehicle body 2.

[0031] In some embodiments, Figure 1 As shown, an automatic hose reel 4 is provided between the oil pump 8 and the oil delivery pipe 5 , and the oil delivery pipe 5 is wound on the automatic hose reel 4 .

[0032] Thus, the oil pipeline 5 is wound on the automatic hose reel 4, making the oil pipeline 5 more convenient to use and maintain.

[0033] In some embodiments, Figure 1 As shown, a volumetric flow meter 6 and a solenoid valve 7 are installed on the oil delivery pipe 5 , and the volumetric flow meter 6 and the solenoid valve 7 are electrically connected to a controller 13 , and the controller 13 is located in the maintenance vehicle body 2 .

[0034] A power supply device 12 is provided in the maintenance vehicle body 2. The power supply device 12 is electrically connected to a controller 13. The controller 13 is a plc controller.

[0035] Therefore, the volumetric flowmeter 6 and the solenoid valve 7 can limit the flow of the oil pipeline 5, open the pipeline that needs to transport oil, and close the pipeline that does not need to transport oil.

[0036] In some embodiments, Figure 1 and Figure 4 As shown, an air compressor 14 is also included, and an output end of the air compressor 14 is fixedly connected to an air supply pipe 141 , and the air supply pipe 141 is threadedly connected to the air inlet pipe 311 .

[0037] It also includes a residual oil treatment box 11, which is fixedly connected to the residual oil conveying pipe 51. An exhaust valve is installed at the upper end of the residual oil treatment box 11, and a discharge port is provided at the lower end of the residual oil treatment box 11. An activated carbon filter layer 111 is installed in the residual oil treatment box 11.

[0038] Therefore, when it is necessary to clean the residual oil, the oil pump 8 is turned off, and the air compressor 14 is turned on to allow the compressed air to enter the resin pipe 31 through the air pipe to blow out the residual oil. At this time, the valve of the residual oil delivery pipe 51 is opened, and the valve of the oil delivery pipe 5 is closed. The residual oil enters the residual oil treatment box 11 through the residual oil delivery pipe 51, and the activated carbon filter layer 111 in the residual oil treatment box 11 filters the residual oil.

[0039] The following is combined with Figure 1-5 Describe a specific embodiment of the utility model:

[0040] like Figure 1-Figure 5As shown, it includes a mining engineering machinery body 1 and a maintenance vehicle body 2. A lubrication point is provided at the location of the shaft of the mining engineering machinery 1, and an oil collecting block 3 is installed on the mining engineering machinery 1. One end of the oil collecting block 3 is provided with a resin tube 31 connected to the lubrication point, and the other end of the oil collecting block 3 is connected to the output pipe of the maintenance vehicle body 2. A one-way sealing valve is provided in the direction from the resin tube 31 to the lubrication point. An air intake pipe 311 is provided at the oil outlet end of the resin tube 31, and a first valve is provided on the air intake pipe 311. A residual oil delivery pipe 51 is fixedly connected to the output pipe of the maintenance vehicle body 2. A second valve is provided on the residual oil delivery pipe 51, and a third valve is provided on the output pipe of the maintenance vehicle body 2 between the driving end of the maintenance vehicle body 2 and the residual oil delivery pipe 51. When the maintenance vehicle body 2 supplies oil to the oil collecting block 3, the first valve and the second valve are closed, and the third valve is opened. When cleaning the residual oil on the inner wall of the resin tube 31, the third valve is closed, and the first valve and the second valve are opened. The air inlet pipe 311 is connected to the air source to supply high-pressure airflow into the resin tube 31. The high-pressure gas entering the resin tube 31 drives the residual oil in the resin tube 31 to be discharged through the residual oil delivery pipe 51.

[0041] In actual use, when the residual oil needs to be cleaned, the oil pump 8 is turned off, and the air compressor 14 is turned on to let the compressed air enter the resin pipe 31 through the air pipe to blow out the residual oil. At this time, the valve of the residual oil delivery pipe 51 is opened, and the valve of the oil delivery pipe 5 is closed. The residual oil enters the residual oil treatment box 11 through the residual oil delivery pipe 51. The activated carbon filter layer 111 in the residual oil treatment box 11 filters the residual oil. The filtered residual oil is transported to the outside from the discharge port and poured back into the oil tank 10. Not only the generated residual oil is treated, but also filtered. The residual oil is reused after filtering, thereby achieving effective treatment of the residual oil in the oil pipe and improving work efficiency.
