Description

Technical Field

[0001] The utility model relates to the technical field of engineering equipment maintenance, in particular to a grease oil channel dredging device. Background Art

[0002] In mining projects on metal mines, the most commonly used machinery is the bulldozer, which has the advantages of small operating area, flexibility, easy transfer, high efficiency in short-distance earth transportation, independent operation in dry and wet land, and can carry out large-scale earth and stone and ore pushing operations.

[0003] Wastewater generated during mining may contain harmful substances such as heavy metals, acidic substances, soluble salts, etc. After being absorbed by the soil, the wastewater is easily contaminated by mechanical equipment. Therefore, affected by the working environment of the mine, most of the oil filling ports of existing bulldozers are easily wrapped by acidic muddy water when in use. The grease is easy to harden when it encounters muddy water, causing the grease oil channel to be blocked, affecting the normal injection of grease, and causing dry grinding between the pin holes. The gap between the pin holes becomes larger and larger, causing machine equipment failure and affecting the normal progress of the project. In order to dredge the grease oil channel after hardening, the prior art often requires the disassembly of the pin shaft to clean the grease oil channel so that the grease can achieve normal lubrication between the pin holes.

[0004] However, bulldozers need to be frequently refilled with grease when working, and there may be more than 30 grease filling ports. The method of clearing the grease oil channel by removing the pin shaft has low maintenance efficiency and is easy to affect the construction progress. Utility Model Content

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

[0014] 1.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-2 As shown, the utility model provides a grease oil channel dredging device, comprising:

[0025] A pressurizing device 10 is connected to a hydraulic hose 11, and the pressurizing device 10 generates pressure to make the hydraulic oil flow in the hydraulic hose 11;

[0026] A transition joint 20, one end of which is connected to the hydraulic hose 11, and the other end is connected to the oil channel port 30;

[0027] The two ends of the transition joint 20 are respectively provided with external threads; the transition joint 20 is provided with a detachable sleeve 21 for changing the outer diameter of one end of the transition joint 20 , and the outer wall of the sleeve 21 is provided with external threads for connecting to the oil channel port 30 .

[0028] The utility model aims to pressurize hydraulic oil into the grease oil channel through a hydraulic device, so as to quickly clear the oil channel and play a lubricating role after the grease in the grease oil channel is hardened, which is conducive to the subsequent injection of grease. The device is applied to large-scale mechanical equipment, such as bulldozers, excavators, etc., so that during maintenance, it is possible to fill the grease between the matching gaps normally without disassembling the pin shaft, bearings and other parts, and achieve the proper lubrication function, effectively reducing the delay in the injection of grease due to the blockage of the grease oil channel in the pin hole, resulting in aggravated wear between the pin shaft and the pin hole.

[0029] The utility model also designs a transition joint 20 of a size that can match the oil passage, so that it can be suitable for connection to oil passage openings 30 of various calibers on mechanical equipment without disassembling and replacing the joint from the hydraulic device; since the process of disassembling and replacing the transition joint 20 from the hydraulic hose 11 is reduced, the dredging and lubrication efficiency of the oil passage openings 30 of different specifications can be improved, thereby saving the maintenance time of the mechanical equipment and reducing the wear degree of the pin hole.

[0030] When using the device to dredge the grease oil passage on the mechanical equipment, specifically, first remove the grease nipple that has been clogged and blocked on the mechanical equipment, then screw one end of the transition joint 20 to the original grease nipple, and screw the other end of the transition joint 20 to the joint of the hydraulic hose 11, and the hydraulic hose 11 is connected to the pressurizing device 10. It should be noted that the pressurizing device 10 is preferably a manual pressurizing pump, and by pressing the pressurizing device 10, the pressurized hydraulic oil penetrates into the clogged grease oil passage through the hydraulic hose 11, and squeezes the clogged grease along the oil passage, and finally is completely discharged from the two ports of the pin hole.

[0031] Whether the grease passage is unblocked or not is determined by whether hydraulic oil can be seen leaking out. When hydraulic oil leaks out, the discharge of the hardened grease at the two ports of the pin hole can be observed. When hardened grease appears at the pin hole port while hydraulic oil leaks out, it can be determined that the oil passage has been unblocked. The hydraulic oil that enters the pin hole temporarily forms a lubricating layer between the matching clearance of the pin hole and the pin shaft. Subsequently, a large amount of grease is normally added to completely replace the lubricating layer formed by the hydraulic oil.

[0032] like Figure 3 As shown, in one embodiment provided by the present utility model, in order to enable the sleeve 21 to be fixedly connected to the transition joint 20, the sleeve 21 and the transition joint 20 are threadedly connected.

[0033] In the above embodiment, the peripheral wall of the transition joint 20 is covered with external threads, which makes it inconvenient to install and disassemble due to the lack of a tool's fulcrum, and is not conducive to improving the efficiency of oil channel dredging.

[0034] In order to solve the above problems, Figure 2-3 As shown, in a preferred embodiment provided by the utility model based on the above-mentioned embodiment, a hexagonal ring edge 22 is provided in the middle of the transition joint 20, and a convex ring 221 extending toward the sleeve 21 is provided on one side of the ring edge 22, and a spacing is left between the convex ring 221 and the outer wall of the transition joint 20 to form an annular cavity.

[0035] In this embodiment, by providing a hexagonal ring edge 22 on the transition joint 20, it is convenient for the staff to use manual or wrench to twist the transition joint 20 so that it can be screwed into or out of the oil channel opening 30, thereby facilitating the installation and disassembly of the transition joint 20 and improving the efficiency of oil channel unblocking during maintenance.

[0036] In order to facilitate the installation and removal of the sleeve 21, Figure 2-3 As shown, in a preferred embodiment of the present invention based on the above embodiments, one end of the sleeve 21 is provided with an outer edge 23 extending along its radial direction, and the peripheral wall of the outer edge 23 is provided with protrusions 231 arranged equidistantly in the circumferential direction.

[0037] In this embodiment, an outer edge 23 and a protrusion 231 are provided on the sleeve 21, so that it is convenient for the staff to twist the sleeve 21, and the installation and removal of the sleeve 21 are convenient. It is also convenient to limit the screwing of the sleeve 21 through the abutment between the outer edge 23 and the protruding ring 221.

[0038] In the above embodiment, the convex ring 221 and the outer edge 23 are in direct contact, which will aggravate the wear between the two and reduce their service life.

[0039] To solve the above problems, please continue to refer to Figure 2-4 As shown, in a preferred embodiment of the present invention based on the above embodiments, a pressure ring 24 made of rubber material is provided between the convex ring 221 and the outer edge 23; wherein the pressure ring 24 is embedded between the inner walls of the convex ring 221 to be fixed.

[0040] In this embodiment, a pressure ring 24 is provided between the convex ring 221 and the outer edge 23 to avoid direct contact between the convex ring 221 and the outer edge 23. The force buffer formed between the two by the pressure ring 24 made of rubber can avoid the aggravation of the wear caused by the convex ring 221 and the outer edge 23 pressing against each other.

[0041] In order to increase the pressure of the hydraulic oil when it enters the oil passage port 30, Figure 4 As shown, in a preferred embodiment provided by the utility model based on the above embodiment, the transition joint 20 includes a large diameter end 25 and a small diameter end 26; wherein the large diameter end 25 and the small diameter end 26 are respectively located on both sides of the ring edge 22; the large diameter end 25 is used to connect the hydraulic hose 11, and the small diameter end 26 is used to connect the oil channel port 30; the inner wall of the large diameter end 25 has a trumpet-shaped structure expanding toward the hydraulic hose 11.

[0042] In this embodiment, by connecting the trumpet-shaped large-diameter end 25 to the hydraulic hose 11, not only the hydraulic hose 11 is easy to connect, but also the pressure of the hydraulic oil entering the small-diameter end 26 can be increased by changing the diameter of the internal channel of the transition joint 20, thereby enhancing the pressure of the hydraulic oil entering the oil channel port 30, which is beneficial to improving the dredging effect of the grease oil channel.

[0043] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
