Description

Technical Field

[0001] The utility model relates to a single-line manual-automatic lubrication system and a loader, belonging to the field of engineering machinery lubrication. Background Art

[0002] Most loaders work in harsh environments such as ports and mines. During the steering and working process, some pins will be affected by dust and mineral soil, rust and wear, and affect the efficiency of the whole machine. At this time, it is necessary to add lubricant to the rotating parts to reduce wear. Traditional loaders are mostly lubricated manually or centrally lubricated by lubrication pumps. The main disadvantage of manual lubrication is that it is necessary to stop the machine to manually oil each lubrication point, which affects work efficiency. In addition, there are more than twenty hinge points, which is time-consuming and labor-intensive. Even some steering points and working device lubrication points are not easy to oil, which is very laborious. The main disadvantage of centralized lubrication with lubrication pumps is that most centralized lubrication is a progressive lubrication system. When the controller is damaged or the distributor is blocked, the lubrication pump is paralyzed. Long-term work will cause wear on the pins and require manual oiling. However, due to the influence of the equipment, some lubrication points inside the frame are not easy to oil, which also affects work efficiency. Summary of the invention

[0003] In view of the above problems existing in the prior art, the utility model provides a single-line manual-automatic lubrication system and a loader.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts a single-line manual-automatic lubrication system, comprising:

[0005] An electrically controlled single-line lubrication pump, comprising an oil tank, an electric pump, a controller and a sensor, wherein the electrically controlled single-line lubrication pump is used to provide lubricating oil;

[0006] A four-way block connected to the electronically controlled single-line lubrication pump via a lubrication pipeline and used for diverting the lubricating oil;

[0007] The distributor comprises a frame distributor installed on the front and rear frames and a working device distributor installed on the working device. The inlet ends of the frame distributor and the working device distributor are respectively connected to the four-way blocks, and the outlet ends are respectively connected to the manual oil injection mounting blocks. The manual oil injection mounting blocks are connected to the lubrication points.

[0008] In some embodiments, the frame distributor is connected to the manual oil filling mounting block through a frame lubrication pipeline, one end of the manual oil filling mounting block is connected to the frame lubrication point, and the other end is blocked by a plug.

[0009] In some embodiments, the frame distributor uses two single-line three-distributors in parallel, one single-line three-distributor is connected to a manual oil filling mounting block installed on the outside of the front frame, and the other single-line three-distributor is connected to a manual oil filling mounting block installed on the outside of the rear frame.

[0010] In some embodiments, the working device distributor is connected to the manual oil filling mounting block through the rocker arm lubrication pipeline, one end of the manual oil filling mounting block is connected to the rocker arm lubrication point, and the other end is blocked by a plug.

[0011] In some embodiments, the working device distributor is also connected to two manual oiling mounting blocks in series through a boom lubrication pipeline, one end of the first manual oiling mounting block is connected to the boom lubrication point, and the other end is connected to the second manual oiling mounting block, and both ends of the second manual oiling mounting block are blocked by plugs.

[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present application are described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the present application, rather than limitations on the technical solutions of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0025] like Figure 1 , Figure 2 As shown, a single-line manual-automatic lubrication system includes an electronically controlled single-line lubrication pump 1, a four-way block 3 and a plurality of distributors;

[0026] The electronically controlled single-line lubrication pump 1 comprises an oil tank, an electric pump, a controller and a sensor. The electronically controlled single-line lubrication pump 1 is used to provide lubricating oil. The electronically controlled single-line lubrication pump 1 adds grease to the pump oil tank through the lubrication pump refueling port 7. The oil tank is equipped with a sensor. When the oil tank is refilled with oil, the oil level exceeds the set oil level, and the sensor provides a signal, the high-pressure cut-off valve is activated, and the electric pump stops refilling oil. When the whole vehicle is working, the plug connector on the controller is connected to the whole machine power supply, and the control program is integrated into the whole machine ECU. The lubrication frequency and the amount of grease can be controlled by controlling the control panel in the cab (it is necessary to calculate the amount of grease consumed in a lubrication cycle according to the lubrication frequency and lubrication amount, and to calculate the volume of the selected lubrication pump if the vehicle works N hours a day and needs to add grease once N days).

[0027] The four-way block 3 is connected to the electric-controlled single-line lubrication pump 1 through a lubrication pipeline, and is used to divert the lubricating oil; the lubrication pipeline is provided with PVC and SG sheaths, and has high safety;

[0028] The distributor includes a frame distributor installed on the front and rear frames and a working device distributor installed on the working device. The inlet ends of the frame distributor and the working device distributor are respectively connected to the four-way block 3, and the outlet ends are respectively connected to the manual oil filling mounting block 6, and the manual oil filling mounting block 6 is connected to the lubrication point.

[0029] In some embodiments, Figure 1 As shown, a filter 2 is installed on the lubrication pipeline between the electronically controlled single-line lubrication pump 1 and the four-way block 3. The filter 2 is located between the oil outlet of the lubrication pump and the four-way block 3, and is installed at the hinge of the rear frame for easy maintenance; it has a quickly resettable blockage indicator. When the filter element is blocked, the red light on the filter 2 triggers an alarm. When the filter element is completely blocked, the grease will safely overflow from the bypass to prevent contaminated grease from entering and exiting the distributor, causing the distributor to be blocked or aggravating the wear of the lubrication points.

[0030] In addition, the main function of the four-way block 3 is to divert the grease from the filter 2 to form a parallel relationship between the front frame, the rear frame and the working device, thereby preventing the entire centralized lubrication system from being paralyzed due to blockage of one lubrication pipeline.

[0031] In some embodiments, the frame distributor can select different distributors according to the number of lubrication points, or a group of distributors can be connected in series. The distributors of the front and rear frames are installed on the outside of the frames to facilitate adjustment of oil output and maintenance.

[0032] The principle of the manual and automatic lubrication of the front and rear frames is the same: when the grease enters the distributor through the four-way block 3, it is divided inside the distributor and enters each pipeline. Then, the grease is added to each lubrication point through the manual oiling mounting block 6 through the lubrication hose, completing a lubrication cycle. The amount of grease at each lubrication point can be adjusted through the distributor (the distributor is equipped with an indicator rod for easy inspection and adjustment).

[0033] The frame distributor is connected to the manual oiling mounting block 6 through the frame lubrication pipeline. One end of the manual oiling mounting block 6 is connected to the frame lubrication point to complete the centralized lubrication direction. The other end is blocked by the plug 8. When the distributor is blocked, the manual oiling mounting block 6 is located outside the frame, and the staff stands at the hinge center of the frame to directly complete the manual oiling of the front and rear frames. The distributor is provided with a one-way valve to prevent the grease from flowing back into the lubrication pump. At this time, the manual oiling method is completed.

[0034] In some embodiments, the frame distributor can adopt two parallel single-line three-distributors 4, one single-line three-distributor 4 is connected to the manual oiling mounting block 6 installed on the outside of the front frame, and the other single-line three-distributor 4 is connected to the manual oiling mounting block 6 installed on the outside of the rear frame, so as to effectively meet the lubrication requirements of the front and rear frames.

[0035] In some embodiments, the lubrication points of the working device are relatively loose relative to the frame. Considering the manual-automatic integration, the pipeline direction will be relatively messy, so two manual oiling installation blocks 6 are connected in series, such as Figure 2 As shown. The connection between the boom and the frame on the working device is higher than the ground. If the lubrication method of the front and rear frames is used (the distributor outlet is directly connected to the lubrication point through the manual oiling mounting block 6), the pipeline will be messy. To avoid this phenomenon, the working device distributor is connected to the two manual oiling mounting blocks 6 in series through the boom lubrication pipeline. One end of the first manual oiling mounting block 6 is connected to the boom lubrication point, and the other end is connected to the second manual oiling mounting block 6. Both ends of the second manual oiling mounting block 6 are blocked by plugs 8. When the distributor is blocked, unscrew the plug 8 and manually oil the lubrication point with a grease gun. Correspondingly, the working device distributor is connected to the manual oiling mounting block 6 through the rocker arm lubrication pipeline. One end of the manual oiling mounting block 6 is connected to the rocker arm lubrication point, and the other end is blocked by a plug 8.

[0036] In some embodiments, Figure 2 As shown, the working device distributor can adopt a single-line three-distributor 4 and a single-line four-distributor 5 connected in series, which effectively meets the lubrication requirements of the boom and the rocker arm.

[0037] A second aspect of the utility model provides a loader, on which the single-line manual-automatic lubrication system is installed.

[0038] The single-line manual-automatic lubrication system of the utility model adopts the form of parallel connection of manual lubrication and centralized lubrication. If one of them is blocked, the other lubrication system can still be used normally, which is more efficient. The control end of the lubrication pump is integrated on the whole machine. As long as the whole machine is powered normally, its oiler can fill oil normally, which is more reliable. The oiling time and oil output of the lubrication pump can be controlled by the controller, which does not require frequent operation by the operator, and is more intelligent.

[0039] In addition, those skilled in the art will understand that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments also means being within the scope of protection of the present utility model and forming different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
