Description

Technical Field

[0001] The invention belongs to the technical field of hydraulic station oil filtering, in particular to an oil filtering device for a hydraulic station in front of a furnace. Background Art

[0002] The hydraulic oil filter trolley in front of the furnace, that is, the hydraulic oil filter trolley, can effectively remove solid impurities in the oil through pressurized filtration, improve oil quality, and can be used as a special equipment for injecting new oil into the hydraulic system or regularly filtering pollutants in the system medium. It is widely used in various occasions that require oil filtration.

[0003] In the prior art, the oil filter device cart is placed on the ground and connected to a power source. Next, the motor and the oil pump are started to extract external hydraulic oil into the filter device, so that the extracted hydraulic oil flows through the filter paper and flows out through the return pipe.

[0004] There are still some problems in the actual application of the above scheme. During the factory production process, the hydraulic station oil filter device trolley is usually placed around the hydraulic station. Since the hydraulic station will generate long-term vibration when working, the oil filter device trolley will be displaced. During the vibration process, the oil filter device will increase the friction between the oil filter device and other equipment pipelines, causing equipment damage, which will increase the company's production costs. At the same time, the movement of the oil filter device trolley will cause the oil inlet and outlet pipelines of the oil filter device to loosen or fall off, and reconnecting the pipelines will take a lot of time, which will reduce the overall efficiency of the oil filtering work. Secondly, the added downward support device cannot adapt to the uneven ground, which will cause uneven force on the downward support device, thereby affecting the stability of the entire equipment. The equipment will shake or tilt during operation, and even cause safety accidents.

[0005] To this end, the present invention provides an oil filter device for a hydraulic station in front of a furnace. Summary of the invention

[0015] Preferably, an adaptive clamping mechanism for adapting to uneven ground is provided at the bottom of the downward pressure support mechanism, an electric guide rail is fixedly provided at the bottom of the mobile trolley, a sliding block is slidably connected to the outer ring surface of the electric guide rail, and a clamping plate is fixedly connected to the end of the sliding block away from the electric guide rail.

[0016] Preferably, the electric guide rails, sliding blocks and clamping plates are symmetrically distributed in two groups about the central axis of the support plate, and semicircular holes are opened on opposite sides of the two groups of clamping plates.

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figures 1 to 8 As shown, an oil filter device for a furnace hydraulic station according to an embodiment of the present invention comprises a mobile trolley 1, a guide port is provided inside the mobile trolley 1, an oil filter device 2 is arranged on the upper part of the mobile trolley 1, the oil filter device 2 comprises an oil storage box 201, an oil pipeline 202 is fixedly connected to the inside of the oil storage box 201, an oil pump 203 is fixedly arranged at one end of the oil pipeline 202 away from the oil storage box 201, an oil inlet pipeline 204 is fixedly connected to the side of the oil pump 203, a first motor 205 is arranged on the side of the oil pump 203, an oil filter paper 206 is fixedly connected to the side wall of the inner cavity of the oil storage box 201, an oil return pipeline 207 is fixedly connected to the lower part of the side of the oil storage box 201, and a downward pressing support mechanism 3 is arranged on the upper part of the mobile trolley 1;

[0037] The downward pressure support mechanism 3 includes a fixed shell 301 fixedly arranged on the upper part of the mobile trolley 1, a reciprocating rack 311 is slidably arranged on the side of the fixed shell 301, and a support plate 314 is fixedly arranged at the bottom of the reciprocating rack 311. The movement of the support plate 314 can fix the mobile trolley 1 when it is working.

[0038] Specifically, during the factory production process, the hydraulic station oil filter device trolley is usually placed around the hydraulic station. Since the hydraulic station will generate long-term vibration during operation, the oil filter device trolley will be displaced. During the vibration process, the oil filter device will increase the friction between other equipment pipelines, causing equipment damage, which will increase the production cost of the enterprise. At the same time, the movement of the oil filter device trolley will cause the oil inlet and outlet pipelines of the oil filter device to loosen or fall off, and reconnecting the pipelines will take a lot of time, which will reduce the overall efficiency of the oil filtering work.

[0039] Therefore, the present invention solves this problem by setting a corresponding structure. In the oil filter device of a pre-furnace hydraulic station described in the present invention, when it is necessary to filter the hydraulic oil, the staff first pushes the mobile trolley 1 and the oil filter device 2 to the designated area and connects the various pipelines. At this time, the hydraulic oil to be filtered is sent into the oil pump 203 through the oil inlet pipeline 204, and at the same time, the first motor 205 is started to drive the oil pump 203 to send the hydraulic oil to be filtered into the oil storage box 201 through the oil delivery pipeline 202. At this time, the hydraulic oil that needs to be filtered that flows into the oil storage box 201 will be filtered through the oil filter paper 206. Since the return oil pipeline 207 is fixed to the lower part of the side of the oil storage box 201 and is located at the oil filter, Paper 206 is away from one side of the oil pipeline 202, so the filtered hydraulic oil will be transported out of the oil storage box 201 through the return oil pipeline 207. However, the hydraulic station will generate long-term vibration when working or the staff will collide with the oil filter device trolley due to operational errors, which will cause the oil filter device trolley to move, thereby causing friction and collision between the oil filter device and other equipment components, causing equipment damage, and then increasing the company's production costs. At this time, the movement of the reciprocating rack 311 drives the support plate 314 to move toward the ground, and stops moving when the bottom of the support plate 314 is close to the ground, thereby reducing equipment failures and downtime caused by movement or vibration, thereby improving work efficiency.

[0040] Embodiment 2

[0041] like Figures 1 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0042] like Figure 4 As shown, in this embodiment, a second motor 302 is fixedly installed on the upper part of the fixed shell 301, and a worm 303 is fixedly connected to the output shaft of the second motor 302. A support platform 304 is provided at the end of the worm 303 away from the second motor 302. The side of the support platform 304 is fixedly connected to the inside of the fixed shell 301, and the worm 303 is rotatably connected to the upper surface of the support platform 304.

[0043] Specifically, when the staff moves the mobile cart 1 and the oil filter device 2 to the specified position, the second motor 302 is started to drive the worm 303 fixed to its output shaft to rotate. At the same time, since the support platform 304 is fixed inside the fixed shell 301, the support platform 304 can provide corresponding support to the worm 303 while the worm 303 rotates.

[0044] like Figure 4 and Figure 6 As shown, in this embodiment, a rotating worm wheel 305 is meshed on the side of the worm 303 , a fixed shaft 306 is fixedly connected to the middle of the rotating worm wheel 305 , and a first arc gear 307 is fixedly connected to one end of the fixed shaft 306 away from the rotating worm wheel 305 .

[0045] Specifically, when the worm 303 rotates, it will drive the rotating worm wheel 305 meshing with it to rotate synchronously. When the rotating worm wheel 305 rotates, it will drive the fixed shaft 306 fixed in the middle thereof to rotate synchronously. At the same time, since the first arc gear 307 is fixed at one end of the fixed shaft 306, when the fixed shaft 306 rotates, it will drive the first arc gear 307 to rotate synchronously, thereby providing corresponding power support for subsequent devices.

[0046] like Figure 4 and Figure 6 As shown, in this embodiment, a first rotating gear 308 is fixedly connected to the middle part of the fixed shaft 306, a second rotating gear 309 is meshed on the outer ring surface of the first rotating gear 308, the second rotating gear 309 is fixedly connected to a second arc gear 310 via a pin, the second arc gear 310 and the second rotating gear 309 are rotatably connected to the side of the fixed shell 301 via a pin, the second arc gear 310 and the first arc gear 307 are oriented in completely opposite directions, and a reciprocating rack 311 is meshed on the outer ring surface of the first arc gear 307.

[0047] Specifically, when the fixed shaft 306 rotates, it will drive the first rotating gear 308 fixed in the middle to rotate synchronously. Since the first rotating gear 308 is meshed with the second rotating gear 309, the second rotating gear 309 will be driven to rotate synchronously when the first rotating gear 308 rotates, and the second arc gear 310 will be driven to rotate synchronously when the second rotating gear 309 rotates. Since the directions of the first arc gear 307 and the second arc gear 310 are completely opposite, the reciprocating motion of the subsequent device can be achieved through the rotation of the first arc gear 307 and the second arc gear 310. At the same time, since the reciprocating rack 311 is meshed with the first arc gear 307, the reciprocating rack 311 will be pushed downward when the first arc gear 307 is meshed with the reciprocating rack 311 and rotates again.

[0048] like Figure 4 and Figure 5 As shown, in this embodiment, a guide block 312 is fixedly connected to the side of the reciprocating rack 311 , a guide groove 313 is opened on the side of the fixed shell 301 , and the guide block 312 is slidably connected inside the guide groove 313 .

[0049] Specifically, when the reciprocating rack 311 moves, since the guide block 312 fixed on the side of the reciprocating rack 311 slides in the guide groove 313 opened on the side of the fixed shell 301, the reciprocating rack 311 will be guided by the guide groove 313 to perform reciprocating linear motion during movement.

[0050] like Figure 3 As shown, a support plate 314 is fixedly connected to the bottom of the reciprocating rack 311 in this embodiment. The support plate 314 is adapted to the size of the guide opening opened inside the moving vehicle 1, and an inner cavity is opened inside the support plate 314.

[0051] Specifically, when the reciprocating rack 311 moves downward, it will drive the support plate 314 fixedly connected to it to move synchronously. When the intersection of the reciprocating rack 311 and the support plate 314 moves to the middle of the guide opening opened inside the mobile trolley 1, the bottom surface of the support plate 314 will be in close contact with the ground, thereby supporting and fixing the device, thereby reducing equipment failures and damages caused by the shaking or movement of the trolley, thereby ensuring the continuity and stability of the work and improving the overall work efficiency. At the same time, the support plate 314 close to the ground can effectively absorb and disperse vibration energy, reduce the displacement and shaking of the trolley caused by vibration, and ensure that the trolley remains stable during work.

[0052] like Figure 7 and Figure 8 As shown, in this embodiment, a reciprocating spring 404 is fixedly connected to the top of the inner cavity of the support plate 314, and the other end of the reciprocating spring 404 is fixedly connected to multiple groups of support columns 405. Guide holes are opened through the support columns 405 and the sides of the support plate 314, and pins 406 are inserted into the guide holes opened on the sides of the support columns 405 and the support plate 314.

[0053] Specifically, when encountering an uneven ground, the support plate 314 is moved above the ground by pressing down the support mechanism 3 and is not in contact with the ground. At this time, the pin 406 is manually pulled out of the support column 405 and the support plate 314. At this time, the reciprocating spring 404 that was originally in a compressed state will gradually reset and push the support column 405 to move toward the ground. Since there are multiple groups of support columns 405 and reciprocating springs 404, when any group of support columns 405 and reciprocating springs 404 encounters a convex ground, the reciprocating spring 404 will be affected by external force and stop resetting, and when encountering a concave ground, it will continue to reset until the bottom of the support column 405 touches the ground and stops resetting.

[0054] like Figure 7 As shown, in this embodiment, an adaptive clamping mechanism 4 for adapting to uneven ground is arranged at the bottom of the downward pressing support mechanism 3, and an electric guide rail 401 is fixedly arranged at the bottom of the mobile vehicle 1. A sliding block 402 is slidably connected to the outer ring surface of the electric guide rail 401, and a clamping plate 403 is fixedly connected to the end of the sliding block 402 away from the electric guide rail 401.

[0055] like Figure 7 As shown, in this embodiment, the electric guide rail 401, the sliding block 402 and the clamping plate 403 are symmetrically distributed in two groups about the central axis of the support plate 314, and semicircular holes are opened on opposite sides of the two groups of clamping plates 403.

[0056] Specifically, when multiple groups of reciprocating springs 404 and support columns 405 adapt to different ground surfaces, the electric guide rail 401 is started. At this time, the electric guide rail 401 will drive the sliding block 402 sliding on its surface to move toward the support plate 314. When the sliding block 402 moves, it will drive the clamping plate 403 fixed thereto to move synchronously. Since the electric guide rail 401, the sliding block 402 and the clamping plate 403 are symmetrically arranged in two groups, and the semicircular holes will form a complete circular hole when the two groups of clamping plates 403 are tightly attached to each other on one side, and the outer ring surface of the support column 405 is clamped, thereby ensuring that the downward support mechanism 3 can adapt to the fixation on uneven ground, providing more stable support, and helping to prevent the overall structure from being displaced or tipped over on uneven ground, thereby improving the applicability of the entire device to different ground surfaces.

[0057] Working principle: when the staff moves the mobile cart 1 and the oil filter equipment 2 to the specified position, the second motor 302 is started to drive the worm 303 fixed to its output shaft to rotate. At the same time, since the support platform 304 is fixed inside the fixed shell 301, the support platform 304 can provide corresponding support to the worm 303 while the worm 303 rotates.

[0058] When the worm 303 rotates, it will drive the rotating worm wheel 305 meshing with it to rotate synchronously. When the rotating worm wheel 305 rotates, it will drive the fixed shaft 306 fixed in the middle to rotate synchronously. At the same time, since the first arc gear 307 is fixed at one end of the fixed shaft 306, when the fixed shaft 306 rotates, it will drive the first arc gear 307 to rotate synchronously, thereby providing corresponding power support for subsequent devices.

[0059] When the fixed shaft 306 rotates, it will drive the first rotating gear 308 fixed in the middle to rotate synchronously. Since the first rotating gear 308 and the second rotating gear 309 are meshed, the second rotating gear 309 will be driven to rotate synchronously when the first rotating gear 308 rotates, and the second arc gear 310 will be driven to rotate synchronously when the second rotating gear 309 rotates. Since the directions of the first arc gear 307 and the second arc gear 310 are completely opposite, the reciprocating motion of the subsequent device can be achieved through the rotation of the first arc gear 307 and the second arc gear 310. At the same time, since the reciprocating rack 311 is meshed with the first arc gear 307, the reciprocating rack 311 will be pushed downward when the first arc gear 307 is meshed with the reciprocating rack 311 and rotates again.

[0060] When the reciprocating rack 311 moves, since the guide block 312 fixed on the side of the reciprocating rack 311 slides in the guide groove 313 opened on the side of the fixed shell 301, the reciprocating rack 311 will be guided by the guide groove 313 to perform reciprocating linear motion during movement.

[0061] When the reciprocating rack 311 moves downward, it will drive the support plate 314 fixed to it to move synchronously. When the intersection of the reciprocating rack 311 and the support plate 314 moves to the middle of the guide opening opened inside the mobile trolley 1, the bottom surface of the support plate 314 will be in close contact with the ground, thereby supporting and fixing the device, thereby reducing equipment failure and damage caused by the shaking or movement of the trolley, thereby ensuring the continuity and stability of the work and improving the overall work efficiency. At the same time, the support plate 314 close to the ground can effectively absorb and disperse vibration energy, reduce the displacement and shaking of the trolley caused by vibration, and ensure that the trolley remains stable during work.

[0062] When encountering an uneven ground, the support plate 314 is moved above the ground by pressing down the support mechanism 3 and is not in contact with the ground. At this time, the pin 406 is manually pulled out of the support column 405 and the support plate 314. At this time, the reciprocating spring 404 that was originally in a compressed state will gradually reset and push the support column 405 to move toward the ground. Since there are multiple groups of support columns 405 and reciprocating springs 404, when any group of support columns 405 and reciprocating springs 404 encounters a convex ground, the reciprocating spring 404 will be affected by external force and stop resetting, and when encountering a concave ground, it will continue to reset until the bottom of the support column 405 touches the ground and stops resetting.

[0063] When multiple groups of reciprocating springs 404 and support columns 405 adapt to different ground surfaces, the electric guide rail 401 is started. At this time, the electric guide rail 401 will drive the sliding block 402 sliding on its surface to move toward the support plate 314. When the sliding block 402 moves, it will drive the clamping plate 403 fixed thereto to move synchronously. Since the electric guide rail 401, the sliding block 402 and the clamping plate 403 are symmetrically arranged in two groups, and the semicircular holes will form a complete circular hole when the two groups of clamping plates 403 are tightly attached to each other on one side, and the outer ring surface of the support column 405 is clamped, thereby ensuring that the downward support mechanism 3 can adapt to the fixation on uneven ground, providing more stable support, and helping to prevent the overall structure from being displaced or tipped over on uneven ground, thereby improving the applicability of the entire device to different ground surfaces.
