Description

Technical Field

[0001] This invention belongs to the technical field of tunneling machine equipment, specifically a lubrication device suitable for lubrication of the saddle slide rail during step change in open-type TBM tunneling. Background Technology

[0002] TBM is a type of tunnel boring machine, a comprehensive piece of equipment that uses mechanical methods to break rocks, remove muck, and provide support for continuous operations. Based on the cutting process at the working face, TBMs are classified into full-face tunnel boring machines (TBMs) and partial-face TBMs.

[0003] However, in existing technologies, during tunneling and step-changing, there is relative movement between the saddle and the main frame of the existing TBM. This relative movement leads to unavoidable wear between the saddle and the main frame. In actual construction, the construction environment and conditions will increase the wear of the main frame and the saddle, which will significantly affect the actual service life of the existing TBM. In addition, the existing lubrication equipment often continuously injects lubricating oil between the main frame and the saddle, which can easily lead to waste of resources and result in poor actual performance of the existing lubrication equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a lubrication device for saddle slide lubrication in open-type TBM tunneling step change, which can effectively reduce wear and avoid waste of resources.

[0005] The technical solution adopted in this invention is as follows: A lubrication device suitable for lubrication of saddle slide rails during step change in open-face TBM tunneling, comprising: a first functional mechanism, the first functional mechanism including a base, a rear main frame body slidably inserted inside the base, and slide strips fixedly connected to the outer surfaces on both sides of the rear main frame body; and

[0006] The second functional mechanism consists of four sets. Each set includes a liquid storage frame and a power component. The liquid storage frame is fixedly connected to the outer surface of the base. A sticker frame is fixedly connected to the top of the liquid storage frame. A sticker is inserted through the inner wall of one side of the sticker frame. A liquid guiding block is embedded inside the sticker frame. A baffle is fixedly connected inside the liquid guiding block. A conveying shaft is rotatably connected between the baffle and the outer surface of one side of the sticker frame. A sealing plate is fixedly connected to the outer surface of the conveying shaft. The power component is located on the sticker frame.

[0007] The base has a set of hydraulic cylinders rotatably connected to both outer surfaces, and a saddle body is rotatably connected between the output ends of the two sets of hydraulic cylinders. The saddle body has a support shoe body fixedly connected to both outer surfaces.

[0008] Each patch has multiple drainage holes equidistantly spaced on its outer surface, and each patch frame has scrapers fixedly connected to both outer surfaces.

[0009] Each of the mounting frames is fixedly connected to a lubricating oil pump at its top, and each of the lubricating oil pumps is connected to a liquid extraction pipe at its input end, with one end of each liquid extraction pipe extending into the corresponding liquid storage frame.

[0010] Each of the lubricating oil pumps has an output end connected to an injection pipe, each injection pipe has a valve on its outer surface, and one end of each injection pipe extends into the corresponding liquid guide block.

[0011] Each of the conveying shafts extends to the outside of the corresponding frame at one end, and a first connecting wheel is fitted on the outer surface of each conveying shaft.

[0012] Each of the attached frames has a reverse tube penetrating one side of its outer surface. One end of each reverse tube extends into the corresponding liquid guiding block, and the other end of each reverse tube penetrates the corresponding liquid guiding block.

[0013] Each of the injection tubes is provided with a first one-way valve on its outer surface, and each of the reverse tubes is provided with a second one-way valve on its outer surface.

[0014] Each set of power components includes a limiting frame, each limiting frame is fixedly connected to the outer surface of the corresponding scraper, each limiting frame is rotatably connected to a connecting tube on one side of its outer surface, each connecting tube is fitted with a first connecting wheel and a second connecting wheel on its outer surface, each connecting tube is slidably inserted with a support rod inside, one end of each support rod slides through the corresponding limiting frame, each support rod is fitted with a pressure plate on its outer surface, each support rod is slidably fitted with a support spring on its outer surface, each support rod is rotatably connected to a support frame on one end, and each support frame is rotatably connected to a rotating wheel between its two sides relative to its inner surface wall.

[0015] Each of the rotating wheels is fixedly connected to one end with a first bevel gear, and each of the limiting frames is rotatably connected to the bottom with a rotating rod. Each rotating rod has a second connecting wheel and a second bevel gear fitted on its outer surface. Each second bevel gear meshes with a corresponding first bevel gear. The eight first connecting wheels are divided into four groups, and a first connecting belt is fitted between the outer surfaces of the two first connecting wheels in each group. The eight second connecting wheels are divided into four groups, and a second connecting belt is fitted between the outer surfaces of the two second connecting wheels in each group.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] In this invention, during use, an appropriate amount of lubricating oil is injected into the storage box, and then the lubricating oil pump is started at regular intervals. This allows the lubricating oil pump to effectively inject the lubricating oil into the guide block through the suction pipe and injection pipe. Under the obstruction of the conveyor shaft, sealing plate, and baffle, the lubricating oil can temporarily remain inside the guide block. Simultaneously, the rotating wheel engages with the corresponding sliding strip. When the rear main frame body and base move relative to the saddle body, the sliding strip effectively drives the rotating wheel to rotate. The rotating wheel, through the first and second bevel gears, effectively drives the rotating rod to rotate. The rotating rod, through the second connecting wheel and second connecting belt, effectively drives the connecting pipe to rotate. The rotating connecting pipe, through the first connecting wheel and first connecting belt, effectively drives the conveyor shaft to rotate. The rotating conveyor shaft effectively pumps the lubricating oil into the guide block. The conveyor shaft effectively delivers lubricating oil to the patch side, and then sprays the lubricating oil onto the outer surface of the slide bar through the patch's drain hole. This effectively reduces wear on the base, saddle body, and slide bar, while also preventing wear on the rear main frame. Replacing the slide bar can also reduce actual construction costs. When the rear main frame undergoes a reverse relative displacement, the rotating wheel rotates in the opposite direction under the action of the slide bar, ultimately causing the conveyor shaft to rotate in the opposite direction. This allows the lubricating oil stored inside the guide block to be delivered to the patch side through the reverse pipe, effectively lubricating the slide bar. Furthermore, the equipment only delivers lubricating oil to the patch side when there is a relative displacement between the rear main frame body and the base and saddle body, effectively preventing excessive use of lubricating oil, avoiding waste of resources, and improving the actual performance of the equipment.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] Example 1

[0029] Reference Figures 1-8A lubrication device for saddle slide lubrication in open-face TBM tunneling step-changing operation includes: a first functional mechanism 1 and a second functional mechanism 2. The first functional mechanism 1 includes a base 101, which provides the mounting foundation for other functional components of the equipment and, together with the saddle body 103, enables the equipment to stably perform its functions. A rear main frame body 105 is slidably inserted inside the base 101, and slide bars 106 are fixedly connected to the outer surfaces of both sides of the rear main frame body 105. The slide bars 106 effectively provide stable support for the rear main frame body 105. The second functional mechanism 2 consists of four sets, each including a liquid storage frame 201 and a power component. The liquid storage frame 201 is fixedly connected to the outer surface of the base 101, and a mounting frame 202 is fixedly connected to the top of the liquid storage frame 201. The mounting frame 202 facilitates the installation of other functional components of the equipment and provides temporary storage space. A patch 208 extends through one side of the inner wall of the frame 202. The patch 208 allows the frame 202 to fit closely to the outer surface of the slide bar 106. A liquid guide block 204 is embedded inside the frame 202. The liquid guide block 204 facilitates the installation of other functional components of the equipment and can effectively store lubricating oil temporarily. A baffle 207 is fixedly connected inside the liquid guide block 204. The baffle 207, together with the sealing plate 206 and the conveying shaft 205, can form an effective sealed space, thereby enabling temporary storage of lubricating oil and allowing the equipment to perform its intended functions. A conveying shaft 205 is rotatably connected between the baffle 207 and one side of the outer surface of the frame 202. The conveying shaft 205 can effectively move and transport lubricating oil. A sealing plate 206 is fixedly connected to the outer surface of the conveying shaft 205. The sealing plate 206 can effectively divide the internal space of the liquid guide block 204. The power component is located on the frame 202.

[0030] Reference Figures 3-8A set of hydraulic cylinders 102 are rotatably connected to both outer surfaces of the base 101. The hydraulic cylinders 102 can effectively adjust the usage state of the saddle body 103. The output ends of the two sets of hydraulic cylinders 102 are rotatably connected to the saddle body 103. Support shoe bodies 104 are fixedly connected to both outer surfaces of the saddle body 103. The support shoe bodies 104 can effectively fix and restrict the position of the equipment. Multiple drainage holes are equidistantly opened on the outer surface of each patch 208. The drainage holes allow lubricating oil to be effectively delivered to the outer surface of the slide bar 106. Scrapers 214 are fixedly connected to both outer surfaces of each patch frame 202. The scrapers 214 can effectively clean the outer surface of the slide bar 106, thereby improving the actual lubrication effect. Each patch frame 208 has multiple drainage holes 214 equidistantly connected to both outer surfaces of the base 101. Each of the 02 components is fixedly connected to a lubricating oil pump 213 at its top. The lubricating oil pump 213 effectively delivers lubricating oil. Each lubricating oil pump 213 has an input end connected to a suction pipe 215, which effectively extracts lubricating oil. One end of each suction pipe 215 extends into the corresponding liquid storage frame 201. Each lubricating oil pump 213 has an output end connected to an injection pipe 211, which effectively injects the lubricating oil drawn by the pump 213 into the liquid guide block 204. Each injection pipe 211 has a valve on its outer surface, which effectively controls the delivery effect of the lubricating oil pump 213. One end of each injection pipe 211 extends into the corresponding liquid guide block 204. Each conveyor shaft 205 extends to the outside of its corresponding mounting frame 202 at one end. A first connecting wheel 219 is fitted onto the outer surface of each conveyor shaft 205. The first connecting wheel 219, in conjunction with a first connecting belt, enables the connecting tube 217 to effectively drive the conveyor shaft 205 to rotate. A reverse tube 209 penetrates one side of the outer surface of each mounting frame 202. The reverse tube 209 allows the conveyor shaft 205 to effectively deliver lubricating oil to the side of the mounting patch 208 when the conveyor shaft 205 rotates in the reverse direction. One end of each reverse tube 209 extends into the interior of its corresponding liquid guiding block 204, and the other end of each reverse tube 209 penetrates the corresponding liquid guiding block 204. A first one-way valve 212 is provided on the outer surface of each injection tube 211. The first one-way valve 212 effectively controls the injection tube 211. The flow direction of the internal lubricating oil is controlled by a second check valve 210 on the outer surface of each reverse pipe 209. The second check valve 210 effectively controls the flow direction of the lubricating oil inside the reverse pipe 209. Each power component includes a limiting frame 216, which facilitates the installation of other functional components and provides effective installation space. Each limiting frame 216 is fixedly connected to the outer surface of one side of the corresponding scraper 214. A connecting pipe 217 is rotatably connected to one side of the outer surface of each limiting frame 216. The connecting pipe 217 facilitates the installation of the first connecting wheel 219 and the second connecting wheel 218. The outer surface of each connecting pipe 217 is fitted with the first connecting wheel 219 and the second connecting wheel 218.Each linkage tube 217 has a support rod 220 slidably inserted inside. The support rod 220 facilitates the installation of other functional components of the equipment. One end of each support rod 220 slides through a corresponding limiting frame 216. A pressure plate is fitted on the outer surface of each support rod 220. The pressure plate allows the support spring 221 to effectively support and limit the position of the support rod 220. A support spring 221 is slidably fitted on the outer surface of each support rod 220. The support spring 221 effectively limits the position of the support rod 220. One end of each support rod 220 is rotatably connected to a support frame 222. The support frame 222 facilitates the installation of the rotating wheel 223. Rotating wheels 223 are rotatably connected between the inner surfaces of both sides of each support frame 222. The rotating wheels 223 can tightly fit the slide bar 106. This provides the rotational power required for the rotating rod 203. Each rotating wheel 223 has a first bevel gear fixedly connected to one end. The first bevel gear, in conjunction with the second bevel gear, enables the rotating wheel 223 to effectively drive the rotating rod 203 to rotate. Each limiting frame 216 has a rotating rod 203 rotatably connected to its bottom. The rotating rod 203, in conjunction with the second connecting wheel 218, effectively drives the connecting tube 217 to rotate. Each rotating rod 203 has a second connecting wheel 218 and a second bevel gear fitted onto its outer surface. Each second bevel gear meshes with a corresponding first bevel gear. The eight first connecting wheels 219 are divided into four groups, with a first connecting belt fitted between the outer surfaces of two first connecting wheels 219 in each group. The eight second connecting wheels 218 are also divided into four groups, with a second connecting belt fitted between the outer surfaces of two second connecting wheels 218 in each group.

[0031] In use, an appropriate amount of lubricating oil is injected into the liquid storage box 201, and then the lubricating oil pump 213 is started at regular intervals. The lubricating oil pump 213 can effectively inject lubricating oil into the liquid guide block 204 through the liquid suction pipe 215 and the liquid injection pipe 211. Under the obstruction of the conveying shaft 205, the sealing plate 206 and the baffle 207, the lubricating oil can be temporarily retained in the liquid guide block 204. At the same time, the rotating wheel 223 is in contact with the corresponding sliding strip 106, so that when the rear main frame body 105 and the base 101 move relative to the saddle body 103, the lubricating oil is released. During operation, the slide bar 106 effectively drives the rotating wheel 223 to rotate, which in turn drives the rotating rod 203 to rotate via the first and second bevel gears. The rotating rod 203 then drives the connecting pipe 217 to rotate via the second connecting wheel 218 and the second connecting belt. The rotating connecting pipe 217 then drives the conveying shaft 205 to rotate via the first connecting wheel 219 and the first connecting belt. The rotating conveying shaft 205 effectively delivers the injected liquid guide block. Inside 204, the conveyor shaft 205 can effectively deliver lubricating oil to one side of the patch 208, and then spray the lubricating oil onto the outer surface of the slide bar 106 through the drain hole of the patch 208. This effectively reduces the wear of the base 101, the saddle body 103 and the slide bar 106, and also effectively prevents wear on the rear main frame body 105. Replacing the slide bar 106 can effectively reduce the actual construction cost. When the rear main frame body 105 undergoes a reverse relative displacement, the rotating wheel 223 moves forward under the action of the slide bar 106. The reverse rotation of the conveyor shaft 205 allows the lubricating oil stored inside the liquid guide block 204 to be transported to the patch 208 side through the reverse pipe 209. This enables the equipment to effectively lubricate the slide bar 106. Furthermore, the equipment only supplies lubricating oil to the patch 208 side when there is relative displacement between the rear main frame body 105 and the base 101 and saddle body 103. This effectively avoids excessive use of lubricating oil, prevents waste of resources, and improves the actual performance of the equipment.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
