Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of splitting machine, in particular to a splitting machine wedge block set with double lubrication. BACKGROUND

[0002] The splitting machine is a kind of equipment for splitting hard materials such as rock, concrete, etc., and is widely used in the fields of construction, engineering construction, ore mining, etc. The splitting machine works by pushing the middle wedge block of the splitting machine wedge block set to the front of the side wedge blocks on both sides, and the forward thrust of the middle wedge block is converted into radial splitting force, so that the hard material is separated. When the splitting machine is working, the relative motion between the middle wedge block and the side wedge blocks on both sides has large friction, and mutual wear and tear is easy to occur, which generates friction heat and easily affects the service life of the wedge block set, so it is necessary to frequently lubricate the middle wedge block and the side wedge blocks with grease. At present, manual brushing or injection of lubricating grease is adopted between the surface of the middle wedge block and the side wedge blocks and the gap. Manual application of lubricating grease requires frequent shutdown, which not only affects the work efficiency, but also increases the labor intensity of workers. At the same time, there are problems such as uncontrollable frequency of application, uneven application, and inability to apply to covered parts (such as the inner side of the wedge block mounting seat), which can cause the service life of the wedge block set of the splitting machine to be too short and increase the cost of replacing the wedge block set. SUMMARY

[0004] The technical scheme adopted by the present application to achieve the above-mentioned purpose is: a wedge block set with double lubrication for a splitting machine, comprising a middle wedge block, side wedge blocks and a wedge block mounting seat, one middle wedge block and two side wedge blocks are mounted in the wedge block mounting seat, the rear end of the wedge block mounting seat is connected with a large oil cylinder of the splitting machine through a guide cylinder, the rear end of the middle wedge block is connected with a piston rod of the large oil cylinder of the splitting machine by penetrating the inner side of the guide cylinder, the opposite two side walls of the wedge block mounting seat are respectively recessed inward to form lubricating cavities, each lubricating cavity is provided with an oil sealing rubber block pressed on the surface of the middle wedge block and a spring pressed on the upper side of the oil sealing rubber block, the outer side of each lubricating cavity is provided with a gland plate for sealing the lubricating cavity, the side wall of the guide cylinder is provided with a lubricating grease filling port, the lubricating grease filled in the guide cylinder can lubricate the surface of the middle wedge block in the guide cylinder, the inner side of each side wedge block is provided with a lubricating oil channel, the lubricating oil channel in each side wedge block comprises a main oil channel, an oil inlet hole and an oil outlet hole, the main oil channel extends from the rear end to the front end of the side wedge block, the oil inlet hole extends inward from the outer wall surface of the rear end of the side wedge block and is communicated with the main oil channel, the side wall of the wedge block mounting seat is provided with a through hole corresponding to the position of the oil inlet hole, the oil outlet hole extends outward from the inner side surface of the side wedge block and is communicated with the main oil channel, the inner side surface of each side wedge block is provided with a plurality of oil outlet holes, each oil outlet hole is communicated with the main oil channel, and a lubricating grease injection pipe can penetrate the through hole of the side wall of the wedge block mounting seat to inject lubricating grease into the oil inlet hole, and the lubricating grease flows out of the oil outlet hole through the main oil channel.

[0005] The further technical scheme of the present application is that the main oil channel extends straight from the rear end surface of the side wedge block to the front end surface of the side wedge block, and the front end and the rear end of the main oil channel are respectively plugged by plugs.

[0006] The further technical scheme of the present application is that the oil outlet hole of the side wedge block extends vertically outward from the inner side surface of the side wedge block and is communicated with the main oil channel, and the spacing between adjacent oil outlet holes on the same side wedge block is not equal.

[0007] The further technical scheme of the present application is that the oil outlet hole of the side wedge block extends vertically outward from the inner side surface of the side wedge block and is communicated with the main oil channel, and the spacing between adjacent oil outlet holes on the same side wedge block is equal.

[0008] The further technical scheme of the present application is that the two lubricating cavities of the side wall of the wedge block mounting seat are respectively located directly behind the two side wedge blocks, and the side wall of the guide cylinder behind the two lubricating cavities is respectively provided with a lubricating grease filling port.

[0009] The further technical scheme of the present application is that the lubricating grease filling port of the guide cylinder is covered with a cover.

[0010] The present invention provides a rock splitter wedge assembly with dual lubrication, which has the following beneficial effects: The invention features a lubrication cavity on the side wall of the wedge mounting base, within which a sealing rubber block and a spring are installed. The sealing rubber block presses against the surface of the middle wedge. A grease inlet is located on the guide cylinder at the rear end of the wedge mounting base. Grease is injected into the grease inlet, lubricating the surface of the middle wedge inside the guide cylinder. The sealing rubber block seals the grease within the lubrication cavity, keeping the middle wedge constantly immersed in grease. During movement, the middle wedge transfers the grease to the adjacent wedges, ensuring proper lubrication between the middle and adjacent wedges. The surfaces between the side wedges are always covered with grease. Lubricating oil channels are provided on the inner sides of the two side wedges, and multiple oil outlet holes are provided on the inner surfaces of the two side wedges. During the operation of the splitter, the automatic oil supply pipe can inject lubricating oil into the lubricating oil channels. The lubricating oil flows out from the oil outlet holes, so that the two side wedges and the middle wedge are evenly lubricated with grease, achieving automatic lubrication of the side wedges and the middle wedges. This effectively reduces the friction and wear between the middle wedges and the side wedges, eliminating the need for manual application. This not only solves the safety hazard problem but also greatly improves the service life of the splitter wedge assembly and reduces the labor intensity of workers.

Detailed Implementation

[0013] like Figure 1As shown, this invention discloses a double-lubricated rock splitter wedge assembly, comprising a central wedge 9, two side wedges 7, and a wedge mounting base 10. Two side wedges 7 are mounted in the wedge mounting base 10, symmetrically arranged on both sides of the central wedge 9. The positioning of the central wedge 9 and the two side wedges 7 within the wedge mounting base 10 is prior art and will not be described in detail here. The rear end of the wedge mounting base 10 is connected to a guide cylinder 13, and the rear end of the guide cylinder 13 is connected to the large hydraulic cylinder 11 of the rock splitter. The connections between the wedge mounting base 10 and the guide cylinder 13, and between the guide cylinder 13 and the large hydraulic cylinder 11 of the rock splitter, are also prior art and will not be described in detail here. The rear end of the central wedge 9 passes through an inner connecting device in the guide cylinder 13 and connects to the piston rod of the large hydraulic cylinder 11 of the rock splitter; that is, the piston rod of the large hydraulic cylinder 11 passes forward through the inner connecting device in the guide cylinder 13 and connects to the rear end of the central wedge 9. The large hydraulic cylinder 11 of the rock splitter provides driving force for the back-and-forth movement of the intermediate wedge 9. How the large hydraulic cylinder 11 of the rock splitter drives the intermediate wedge 9 to move back and forth is also existing technology and will not be described in detail here. Figure 1 The direction indicated by the middle arrow F is forward.

[0014] like Figure 1 As shown, the wedge mounting base 10 has lubrication cavities 16 recessed inward on its opposite side walls. Figure 1 Only one side of the lubrication chamber 16 is shown in the diagram. Figure 1 Opposite to the lubrication cavity 16 shown (i.e., below the wedge mounting base 10), there is also a lubrication cavity 16. Each lubrication cavity 16 contains a sealing rubber block 4 pressing against the surface of the middle wedge 9 and a spring 3 pressing against the upper side of the sealing rubber block 4. The rear end of the wedge mounting base 10 is fitted onto the front end of the guide cylinder 13. The sealing rubber block 4 is located within the lubrication cavity 16 and also presses against the front surface of the guide cylinder 13. A pressure plate 5 is provided on the outside of the lubrication cavity 16 to seal it, and the pressure plate 5 is fixed with screws. A grease filling port 1 is provided on the side wall of the guide cylinder 13, and a cap 12 is provided outside the grease filling port 1. The grease injected into the guide cylinder 13 through the grease filling port 1 is stored in the lubrication cavity 16. Figure 1 The diagram illustrates grease 2 entering the lubrication cavity through the grease filling port. In this embodiment, the two lubrication cavities 16 on the side wall of the wedge mounting base 10 are located directly behind the two adjacent wedges 7. The guide cylinder 13 has grease filling ports 1 on its side wall behind the two lubrication cavities 16. The grease filling ports 1 of the guide cylinder 13 are covered with caps 12, which prevent the grease in the guide cylinder 13 from flowing out quickly. Since the spring 3 is in an elastic deformation state due to the pressure plate 5, the sealing rubber block 4 is always elastically pressed, sealing the grease in the lubrication cavity 16, keeping the middle wedge constantly immersed in the grease. When the middle wedge moves, it transfers the grease to the adjacent wedges, ensuring that there is always grease on the surface between the middle wedge and the adjacent wedges.

[0015] like Figure 1 , Figure 2 As shown, lubricating oil channels are respectively provided on the inner side of the two side wedges 7. The lubricating oil channels in each side wedge 7 include a main oil channel 15, an oil inlet 6, and an oil outlet 8. The main oil channel 15 is formed by extending from the rear end to the front end inside the side wedge 7. The main oil channel 15 extends straight forward from the rear end face of the side wedge 7 and passes through the front end face of the side wedge 7. The front end and rear end of the main oil channel 15 are sealed by plugs. The plugs are not shown in the figure. After machining the main oil channel 15, the oil inlet 6, and the oil outlet 8, the iron filings are cleaned and the plugs can be installed at the front end and rear end of the main oil channel 15. The oil inlet 6 extends inward from the outer wall surface of the side wedge 7 near its rear end and communicates with the main oil passage 15. The side wall of the wedge mounting base 10 has a through hole 14 corresponding to the position of the oil inlet 6. The oil outlet 8 extends outward from the inner surface of the side wedge 7 and communicates with the main oil passage 15. The inner surface of each side wedge 7 has multiple oil outlet holes 8 arranged at intervals, and each oil outlet hole 8 communicates with the main oil passage 15. In this embodiment, the oil outlet holes 8 of the side wedge 7 extend vertically outward from the inner surface of the side wedge 7 and communicate with the main oil passage 15. Each oil outlet hole 8 is perpendicular to the main oil passage 15. The diameter of the main oil passage 15 is larger than the diameter of the oil outlet hole 8. The spacing between adjacent oil outlet holes 8 on the same side wedge 7 is equal. The oil supply pipe can penetrate the through hole 14 in the side wall of the wedge mounting base 10 to inject grease into the oil inlet 6. The grease flows out through the main oil passage 15 and the oil outlet hole 8, automatically lubricating the side wedge 7 and the middle wedge 9. As a variation of the present invention, multiple oil inlet holes can also be provided on the rear side of the side wedge. Each oil inlet hole only needs to be connected to the main oil passage. The spacing between adjacent oil outlet holes on the same side wedge can also be unequal, as long as the lubrication requirements between the middle wedge and the side wedge are met. The grease rotation mechanism 18 is installed outside the guide cylinder 13 at the front end of the large oil cylinder 11 of the splitter, such as... Figure 2 As shown, one end of the grease outlet pipe 17 is connected to the oil outlet of the grease rotary mechanism 18, and the other end of the grease outlet pipe 17 can pass through the through hole 14 on the side wall of the wedge mounting base 10 and connect to the oil inlet hole 6 of the adjacent wedge 7. The grease inlet pipe 19 of the grease rotary mechanism 18 is connected to the automatic oil supply device (not shown in the figure).

[0016] Before operation, install the middle wedge 9 and the side wedges 7 in the wedge mounting base 10. Connect the guide cylinder 13 to the rear end of the wedge mounting base 10, and connect the grease rotary mechanism 18 to the guide cylinder 13. Then connect the large oil cylinder 11 of the splitter to the guide cylinder 13. Next, install the oil pipes, automatic oil supply device, and power device (not shown in the figure). The wedge assembly has a dual lubrication function. The first lubrication: after opening the cover 12, add a certain amount of grease through the grease filling port 1, then replace the cover 12. The pressure plate 5 presses the spring 3 against the sealing rubber block 4, which can seal the grease inside the wedge mounting base 10. In this way, the grease can soak the wedge assembly without leaking out. The grease in the lubrication cavity 16 can provide long-term lubrication to the surfaces between the wedge assemblies. Secondary lubrication: When the splitter performs the splitting action (the middle wedge 9 moves forward), grease is injected into the grease rotary mechanism 18 through the grease inlet pipe 19. After being injected into the grease rotary mechanism 18, the grease is injected into the lubrication channel of the adjacent wedge 7 through the grease outlet pipe 17. The grease injected from the oil inlet 6 is evenly attached to the surface of the wedge group through the oil outlet. It is injected once every (1-5) splitting actions (the injection frequency depends on the characteristics of the rock).

Any modifications, equivalent substitutions, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
