Abstract
Description
Technical Field
[0001] This utility model relates to the field of splitting machine technology, and in particular to a splitting machine wedge block assembly with double lubrication. Background Technology
[0002] A rock splitter is a device used to split hard materials such as rock and concrete, and is widely used in construction, engineering, and mining. The rock splitter works by having the central wedge push forward against the adjacent wedges in its wedge assembly. The forward thrust of the central wedge is converted into a radial splitting force, separating the hard material. During operation, the relative motion between the central and adjacent wedges creates significant friction, leading to wear and heat generation, which can severely impact the lifespan of the wedge assembly. Therefore, frequent grease lubrication of the central and adjacent wedges is necessary. Currently, manual application of grease is used to brush or inject grease onto the surfaces and gaps of the central and adjacent wedges. However, manual application requires frequent machine shutdowns, reducing efficiency, increasing worker workload, and causing problems such as uncontrollable application frequency, uneven application, and failure to reach covered areas (e.g., the inside of the wedge mounting base). This results in a shortened lifespan for the rock splitter's wedge assembly and increased replacement costs. Utility Model Content
[0003] The purpose of this invention is to address the deficiencies of the existing technology by providing a splitting machine wedge assembly with dual lubrication. The inner side of the wedge mounting base and the space between the middle wedge and the adjacent wedges are always automatically lubricated with grease, eliminating the need for manual application. This not only solves the safety hazard problem but also significantly improves the service life of the splitting machine wedge assembly.
[0004] The technical solution adopted by this utility model to achieve the above-mentioned objectives is as follows: a splitting machine wedge block assembly with double lubrication, including a middle wedge block, two side wedge blocks, and a wedge block mounting base. One middle wedge block and two side wedge blocks are installed in the wedge block mounting base. The rear end of the wedge block mounting base is connected to the large hydraulic cylinder of the splitting machine through a guide cylinder. The rear end of the middle wedge block passes through the inner side of the guide cylinder and is connected to the piston rod of the large hydraulic cylinder of the splitting machine. The wedge block mounting base has lubrication chambers recessed inward on opposite side walls. Each lubrication chamber is provided with a sealing rubber block pressing on the surface of the middle wedge block and a spring pressing on the upper side of the sealing rubber block. A pressure plate is provided on the outside of the lubrication chamber to seal the lubrication chamber. A grease filling port is provided on the side wall of the guide cylinder, through which grease is injected into the guide cylinder. The grease can lubricate the surface of the middle wedge inside the guide cylinder. Lubricating oil passages are provided on the inner sides of the two side wedges. Each side wedge has a main oil passage, an oil inlet hole, and an oil outlet hole. The main oil passage extends from the rear end to the front end inside the side wedge. The oil inlet hole extends inward from the outer wall surface near the rear end of the side wedge and communicates with the main oil passage. The side wall of the wedge mounting base has a through hole corresponding to the position of the oil inlet hole. The oil outlet hole extends outward from the inner surface of the side wedge and communicates with the main oil passage. The inner surface of each side wedge has multiple oil outlet holes, and each oil outlet hole communicates with the main oil passage. The oil supply pipe can penetrate the through hole in the side wall of the wedge mounting base to inject grease into the oil inlet hole. The grease flows out through the main oil passage and the oil outlet hole.
[0005] A further technical solution of this utility model is: the main oil passage extends in a straight line from the rear end face of the side wedge block and penetrates the front end face of the side wedge block, and the front end and rear end of the main oil passage are respectively sealed by plugs.
[0006] A further technical solution of this utility model is: the oil outlet hole of the side wedge extends vertically outward from the inner surface of the side wedge and communicates with the main oil passage, and the spacing between adjacent oil outlet holes on the same side wedge is not equal.
[0007] A further technical solution of this utility model is: the oil outlet hole of the side wedge extends vertically outward from the inner surface of the side wedge and communicates with the main oil passage, and the spacing between adjacent oil outlet holes on the same side wedge is equal.
[0008] A further technical solution of this utility model is: two lubrication chambers on the side wall of the wedge block mounting seat are located directly behind the two adjacent wedge blocks, and grease filling ports are respectively provided on the side wall of the guide cylinder behind the two lubrication chambers.
[0009] A further technical solution of this utility model is: the grease filling port of the guide cylinder is covered with a cap.
[0010] This utility model discloses a splitter wedge assembly with dual lubrication, which has the following beneficial effects: The utility model provides a lubrication cavity on the side wall of the wedge mounting seat, and a sealing rubber block and a spring are installed inside the lubrication cavity. The sealing rubber block presses against the surface of the middle wedge. A grease filling port is provided at the rear end of the wedge mounting seat guide cylinder. Grease is injected into the grease filling port, and the grease lubricates the surface of the middle wedge inside the guide cylinder. The sealing rubber block seals the grease in the lubrication cavity, keeping the middle wedge constantly immersed in grease. When the middle wedge moves, it transfers the grease to the adjacent wedges, ensuring the lubrication of the middle wedge. The surfaces between the two adjacent wedges are always lubricated with grease. Lubricating oil channels are provided on the inner sides of the two adjacent wedges, and multiple oil outlet holes are provided on the inner surfaces of the two adjacent 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 adjacent wedges and the middle wedge are evenly lubricated with grease, achieving automatic lubrication of the adjacent wedges and the middle wedges. This effectively reduces the friction and wear between the middle wedge and the adjacent 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.
[0011] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates a splitting wedge assembly with dual lubrication according to the present invention. Attached Figure Description

Detailed Implementation
[0013] like Figure 1As shown, this utility model discloses a double-lubricated rock splitter wedge assembly, including 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 the inner connecting device of 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 of 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 this utility model, 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 needs 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 this utility model should be included within the protection scope of this utility model.
