Description

Technical Field

[0001] The invention relates to the field of railway equipment maintenance, and in particular to a mobile equipment for railway train maintenance. Background Art

[0002] A railway train refers to a vehicle combination system that runs on railway tracks. In order to ensure that the railway train can run safely, it is necessary to regularly inspect and maintain the railway train to ensure its safety every time it is used.

Due to the narrow space, they will encounter difficulties when they have to adjust their position or use tools, which in turn affects the smoothness and efficiency of the inspection work. This limitation not only increases the operation time, but also may increase the risk of errors due to frequent movements and adjustments, thereby reducing the overall inspection efficiency and safety.

[0018] The beneficial effects of the present invention are as follows:

[0019] By setting an expansion structure, the motor is started to drive the rotating shaft to rotate, and then the two screw rods 1 are driven to rotate synchronously in opposite directions through the bevel gear 2 and the two bevel gears 1 meshing therewith, and then the two connecting plates are driven to slide along the two through grooves and in the directions away from each other, so that the two horizontal slides move in the directions away from each other, thereby increasing the activity space of personnel on the top of the lifting plate, thereby not only shortening the operation time, but also reducing the risk of increased errors due to frequent movement and adjustment, thereby improving the overall maintenance efficiency and safety of the mobile equipment;

[0020] By setting a quick connection structure, the quick connection structure can quickly fix the extension block and the rotating guard plate to each other or quickly release the fixation. When the extension block and the rotating guard plate are connected, since the extension block is fixedly connected to the second sliding vertical plate, the extension block and the rotating guard plate can be quickly connected through the quick connection structure, which not only makes the rotating guard plate unable to rotate in a vertical state, thereby blocking and protecting the front part of the lifting plate, but also makes the rotating guard plate and the second sliding vertical plate move together when the horizontal sliding plate is driven to move by the expansion structure, thereby making the activity space of the lifting plate larger, and one side of the lifting plate is also protected to prevent people from falling from one side of the lifting plate;

[0021] When the horizontal slide plate is at the longest sliding distance, it is necessary to release the connection between the extension block and the rotating guard plate, and rotate the rotating guard plate to a horizontal position, thereby further expanding the activity space of the lifting plate;

[0022] When the rotating guard plate is in a vertical state, the sliding guard plate is slid upward, driving the two connecting rods three and the sliding rod to move upward. When the sliding rod moves up to the highest state, there is a distance between the bottom of the sliding guard plate and the top of the rotating guard plate. At this time, the sliding guard plate is rotated along the center of the circle of the sliding rod. When the sliding guard plate is rotated to a horizontal state, the sliding guard plate is moved downward again, and the two connecting rods three move downward along the two connecting grooves. When the connecting rod three moves to the bottom of the connecting groove, the sliding guard plate cannot continue to move downward, so that the sliding guard plate is in a stable state at this time, so that the tools required for maintenance can be placed on the top of the sliding guard plate at this time;

[0023] When the rotating guard plate and the sliding guard plate are in a horizontal state, the sliding guard plate is driven to move similarly, so that the sliding guard plate is in a vertical state. At this time, the two sliding plug rods are lowered, so that the two sliding plug rods are respectively engaged with the two connecting grooves, so that the sliding guard plate cannot rotate in this state, and then when the rotating guard plate is rotated to a horizontal state, thereby further increasing the activity space of the lifting plate, the front and rear parts of the lifting plate can still be protected by the sliding guard plate;

[0024] When the rotating guard plate rotates to a horizontal state, thereby further increasing the movable space of the lifting plate, pull the sliding vertical plate 2 so that one side of the rotating guard plate in the horizontal state is closed by the sliding vertical plate 2, so that when the rotating guard plate is in a horizontal state, its rear part can still provide a protective effect.

[0038] 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.

[0039] like Figure 1 - Fig.12 As shown, a mobile device for railway train maintenance includes a bottom plate 1, a lifting plate 3 is arranged on the top of the bottom plate 1, a fixed vertical plate 4 is fixedly connected to the rear of the lifting plate 3, a rotating shaft is rotatably installed at the front and rear of the bottom of the bottom plate 1, moving wheels 2 are fixedly connected at both ends of the two rotating shafts, and an expansion structure 5 is arranged at the bottom of the lifting plate 3;

[0040] The expansion structure 5 includes two horizontal slides 16, and through grooves 17 are provided at the bottom of the front and rear parts of the interior of the lifting plate 3. The two horizontal slides 16 are slidably connected to the interior of the lifting plate 3, and the front and rear parts of the two horizontal slides 16 respectively penetrate the front and rear parts of the lifting plate 3, and the bottoms of the two horizontal slides 16 respectively penetrate the two through grooves 17, and connecting plates 24 are fixedly installed at the bottoms, and two pairs of fixed blocks 3 18 are symmetrically fixedly installed at the bottom of the lifting plate 3, and two screw rods 19 are rotatably connected between each pair of fixed blocks 3 18. The two connecting plates 24 are respectively threadedly connected to the two screw rods 19, and the adjacent ends of the two screw rods 19 respectively penetrate the two fixed blocks 3 18 near the middle and are fixedly connected to bevel gears 1 20. The bottom of the lifting plate 3 is rotatably connected to a rotating shaft 22, and one end of the rotating shaft 22 is fixedly connected to a bevel gear 2 21, and a motor 23 is fixedly installed at the rear of the lifting plate 3.

[0041] In this embodiment, two fixed blocks 7 are symmetrically fixedly installed at the front of the top of the bottom plate 1, a connecting shaft 8 is rotatably connected between the two fixed blocks 7, connecting rods 10 are fixedly installed at both ends of the outer surface of the connecting shaft 8, and two hydraulic rods 9 are fixedly connected between the two connecting rods 10 on the outer surface of the connecting shaft 8, two fixed slide rails 11 are symmetrically fixedly installed at the rear of the top of the bottom plate 1, and connecting rods 2 12 are slidably connected to the opposite sides of the two fixed slide rails 11, and connecting shafts 2 13 are connected between the two connecting rods 10 and between the two connecting rods 2 12, two fixed blocks 2 14 are symmetrically fixedly installed at the front of the bottom of the lifting plate 3, and the opposite sides of the two connecting rods 2 12 are rotatably connected to the two fixed blocks 2 14 respectively at one end, and two fixed slide rails 2 15 are symmetrically fixedly installed at the rear of the bottom of the lifting plate 3, and the adjacent sides of the two connecting rods 10 are slidably connected to the two fixed slide rails 2 15 respectively, and the output ends of the two hydraulic rods 9 are rotatably connected to the connecting shaft 2 13;

[0042] The output ends of the two hydraulic rods 9 extend synchronously, and through the connecting shaft 2 13, drive one end of the two connecting rods 10 to rotate counterclockwise along the connecting shaft 1 8, and the other ends of the two connecting rods 10 slide along the fixed slide rail 2 15 respectively, and one end of the two connecting rods 2 12 slides along the fixed slide rail 11 respectively, and the other ends of the two connecting rods 2 12 rotate along the two fixed blocks 2 14 respectively, so that the lifting platform 3 rises, and then the personnel standing on the top of the lifting platform 3 are lifted to a high place, and the other side of the lifting platform 3 faces the maintenance point of the train, so that the personnel can inspect the maintenance point at a high place of the train.

[0043] In this embodiment, the output end of the motor 23 is fixedly connected to the other end of the rotating shaft 22, and the bevel gear 21 is meshedly connected with the two bevel gears 1 20;

[0044] The motor 23 is started to drive the rotating shaft 22 to rotate, and then the two screw rods 19 are driven to rotate synchronously in opposite directions through the bevel gear 21 and the two bevel gears 1 20 meshing therewith, thereby driving the two connecting plates 24 to slide along the two through grooves 17 and in directions away from each other, thereby causing the two horizontal slides 16 to move in directions away from each other, thereby increasing the activity space for personnel on the top of the lifting plate 3.

[0045] In this embodiment, a rotation groove 25 is provided on one side of the two horizontal slides 16 and passes through the other side. The rotation groove 25 is internally rotatably connected to a limit shaft 26. The top of the horizontal slide 16 is rotatably connected to a rotation guard plate 27 through the limit shaft 26.

[0046] The rotating guard plate 27 can protect the front and rear of the lifting plate 3 to prevent people from falling from the front and rear of the lifting plate 3, thereby ensuring the safety of the people.

[0047] In this embodiment, the rear portion of the bottom of the rotating guard plate 27 contacts the top of the horizontal slide 16, and the front portion of the bottom of the rotating guard plate 27 does not contact the top of the horizontal slide 16. The limiting shaft 26 is semi-cylindrical. When the rotating guard plate 27 rotates to a horizontal state, the rotating guard plate 27 cannot continue to rotate due to the limitation of the limiting shaft 26 and the rotating groove 25. Therefore, the maximum rotation angle of the rotating guard plate 27 is ninety degrees.

[0048] In this embodiment, the front and rear of the fixed vertical plate 4 are both provided with a quick-connect structure 6, and the quick-connect structure 6 includes an insert block 31 and two baffles 32. The front of the fixed vertical plate 4 is provided with an extension block 28, and the insert block 31 is slidably connected to the inside of the extension block 28 and passes through one side of the extension block 28. A tooth groove 1 is provided at the front and rear side of the insert block 31, and a placement groove is provided on one side of the rotating guard plate 27. The two baffles 32 are respectively slidably connected to the front and rear of the placement groove, and the adjacent surfaces of the two baffles 32 are provided with a tooth groove 2. The other side of the insert block 31 passes through the other side of the extension block 28 and is fixedly connected with three fixing rods 29. A spring 30 is fixedly connected between one end of the two fixing rods 29 near the top and the bottom and the other side of the extension block 28 and located on the outer surface of the fixing rod 29;

[0049] The faces away from each other of the two baffles 32 respectively penetrate the front and rear of the rotating guard plate 27 and are fixedly connected with three fixing rods 2 33, one end of the fixing rod 2 33 is fixedly connected with a spring 2 34 between the rotating guard plate 27 and the outer surface of the fixing rod 2 33, the top of the two baffles 32 penetrates the top of the rotating guard plate 27 and is fixedly connected with a squeeze plate 35, the top of the rotating guard plate 27 is located on one side of the two squeeze plates 35 and is slidably connected with a push block 36, the top of the rotating guard plate 27 is located on one side of the push block 36 and is fixedly connected with two fixing blocks 4 37, one side of the push block 36 respectively penetrates the two fixing blocks 4 37 and is fixedly connected with a fixing rod 3 38, one end of the fixing rod 3 38 is fixedly connected with a spring 39 between the side of the fixing block 4 37 and the outer surface of the fixing rod 3 38;

[0050] Since the extension block 28 is fixedly connected to the second sliding vertical plate 46, the extension block 28 can be quickly connected to the rotating guard plate 27 through the quick connection structure 6, which not only makes the rotating guard plate 27 unable to rotate in a vertical state, thereby blocking and protecting the front of the lifting plate 3, but also drives the rotating guard plate 27 and the second sliding vertical plate 46 to move together when the horizontal sliding plate 16 is driven by the expansion structure 5, thereby increasing the activity space of the lifting plate 3, and protecting one side of the lifting plate 3 to prevent people from falling from one side of the lifting plate 3;

[0051] The operation steps of the quick-connect structure 6 are as follows: the insert block 31 is driven to move by the middle fixed rod 1 29, at which time the two springs 1 30 are compressed, and when the insert block 31 is inserted along the inside of the placement slot, the inclined surface of the tooth slot 1 will contact and squeeze the tooth slot 2, so that the two baffles 32 are squeezed and slide in the direction away from each other, and the multiple springs 2 34 are compressed until the insert block 31 is completely inserted into the placement slot, and the multiple springs 2 34 rebound to drive the two baffles 32 to reset, so that the tooth slot 1 and the tooth slot 2 are engaged with each other. At this time, the two springs 1 30 have the desire to rebound and drive the insert block 31 to reset, but the reset of the insert block 31 will make the vertical surface of the tooth slot 1 contact the tooth slot 2, thereby making it impossible for the insert block 31 to reset, and thus the connection between the extension block 28 and the rotating guard plate 27 is completed;

[0052] When the horizontal slide plate 16 is at the longest sliding distance, it is necessary to release the connection between the extension block 28 and the rotating guard plate 27, and rotate the rotating guard plate 27 to a horizontal position. At this time, the activity space of the lifting plate 3 is further expanded. The specific steps are: pushing the push block 36. In the process of pushing the push block 36, the other side of the push block 36 is squeezed with one side of the two squeezing plates 35, so that the two squeezing plates 35 are squeezed and slide in a direction away from each other, thereby driving the two baffles 32 to move in a direction away from each other, so that the tooth groove 1 is disengaged from the tooth groove 2. At this time, the insert block 31 is in a released state, so that the two springs 1 30 rebound, driving the insert block 31 to reset, thereby releasing the connection between the rotating guard plate 27 and the extension block 28.

[0053] In this embodiment, one side of the two squeezing plates 35 is provided with mutually symmetrical inclined plane 1, and the other side of the push block 36 is provided with inclined plane 2 at the front and rear, and the angles between inclined plane 1 and inclined plane 2 are complementary.

[0054] In this embodiment, the tooth groove 1 is composed of a plurality of inclined surfaces and vertical surfaces, and the tooth groove 1 is adaptively matched with the tooth groove 2.

[0055] In this embodiment, the inside of the two rotating guard plates 27 are both provided with a slide groove 40 through the top, and the inside of the slide groove 40 is slidably connected with a sliding guard plate 41, and the bottom of the sliding guard plate 41 is fixedly connected with two connecting rods 42, and the bottom of the two connecting rods 42 is fixedly connected with a sliding rod 43, and the sliding rod 43 is slidably connected with the slide groove 40. The adjacent surfaces of the two rotating guard plates 27 are provided with two connecting grooves 44, and the connecting groove 44 penetrates the top of the rotating guard plate 27, and the connecting groove 44 is connected with the slide groove 40. The other side of the two rotating guard plates 27 is respectively penetrated by the top and the bottom of the two slide grooves 40 and is threadedly connected with a screw, and the same end of the two sliding rods 43 is provided with a thread groove, and the thread and the thread groove are adaptively matched;

[0056] When the rotating guard plate 27 is in a vertical state, the sliding guard plate 41 is slid up, driving the two connecting rods 3 42 and the sliding rod 43 to move upward. When the sliding rod 43 moves up to the highest state, there is a distance between the bottom of the sliding guard plate 41 and the top of the rotating guard plate 27. At this time, the sliding guard plate 41 is rotated along the center of the circle of the sliding rod 43. When the sliding guard plate 41 is rotated to a horizontal state, the sliding guard plate 41 is moved down again, and the two connecting rods 3 42 move down along the two connecting grooves 44. When the connecting rod 3 42 moves to the bottom of the connecting groove 44, the sliding guard plate 41 cannot continue to move downward. At this time, the screw rod near the bottom is rotated so that the screw rod near the bottom is engaged with the thread groove near the bottom, so that the sliding rod 43 is in a fixed state at this position, so that the sliding guard plate 41 is in a stable state at this time, so that the tools required for maintenance can be placed on the top of the sliding guard plate 41 at this time.

[0057] When the rotating guard plate 27 and the sliding guard plate 41 are in a horizontal state, the sliding guard plate 41 is also driven to move, so that the sliding guard plate 41 is in a vertical state. At this time, the two sliding rods are lowered so that the two sliding rods are respectively engaged with the two connecting grooves 44, so that the sliding guard plate 41 cannot rotate when it is in this state. Therefore, when the rotating guard plate 27 is rotated to a horizontal state, thereby further increasing the activity space of the lifting plate 3, the front and rear parts of the lifting plate 3 can still be protected by the sliding guard plate 41.

[0058] In this embodiment, a sliding vertical plate 1 45 is slidably connected to the front and rear parts of the fixed vertical plate 4, and a sliding vertical plate 2 46 is slidably connected to the front part of the sliding vertical plate 1 45. The front part of the sliding vertical plate 2 46 is fixedly connected to the rear part of the extension block 28.

[0059] When the rotating guard plate 27 rotates to a horizontal state, thereby further increasing the movable space of the lifting plate 3, the sliding vertical plate 46 is pulled so that one side of the rotating guard plate 27 in a horizontal state is closed by the sliding vertical plate 46, so that when the rotating guard plate 27 is in a horizontal state, its rear part can still provide a protective effect.

[0060] It should be noted that the present invention is a mobile device for railway train maintenance. When in use, the output ends of the two hydraulic rods 9 are synchronously extended, and through the connecting shaft 13, one end of the two connecting rods 10 is driven to rotate counterclockwise along the connecting shaft 8, and the other ends of the two connecting rods 10 slide along the fixed slide rail 15, and one end of the two connecting rods 12 slides along the fixed slide rail 11, and the other ends of the two connecting rods 12 rotate along the two fixed blocks 14, so that the lifting plate 3 rises, and then the personnel standing on the top of the lifting plate 3 are lifted to a high place, and the other side of the lifting plate 3 faces the train maintenance point, so that the personnel can perform maintenance on the high maintenance point of the train;

[0061] The motor 23 is started to drive the rotating shaft 22 to rotate, and then the two screw rods 19 are driven to rotate synchronously in opposite directions through the bevel gear 21 and the two bevel gears 1 20 meshing therewith, and then the two connecting plates 24 are driven to slide along the two through grooves 17 and in the direction away from each other, so that the two horizontal slide plates 16 move in the direction away from each other, thereby increasing the activity space of the personnel on the top of the lifting plate 3;

[0062] The faces away from each other of the two baffles 32 respectively penetrate the front and rear of the rotating guard plate 27 and are fixedly connected with three fixing rods 2 33, one end of the fixing rod 2 33 is fixedly connected with a spring 2 34 between the rotating guard plate 27 and the outer surface of the fixing rod 2 33, the top of the two baffles 32 penetrates the top of the rotating guard plate 27 and is fixedly connected with a squeeze plate 35, the top of the rotating guard plate 27 is located on one side of the two squeeze plates 35 and is slidably connected with a push block 36, the top of the rotating guard plate 27 is located on one side of the push block 36 and is fixedly connected with two fixing blocks 4 37, one side of the push block 36 respectively penetrates the two fixing blocks 4 37 and is fixedly connected with a fixing rod 3 38, one end of the fixing rod 3 38 is fixedly connected with a spring 39 between the side of the fixing block 4 37 and the outer surface of the fixing rod 3 38;

[0063] Since the extension block 28 is fixedly connected to the second sliding vertical plate 46, the extension block 28 can be quickly connected to the rotating guard plate 27 through the quick connection structure 6, which not only makes the rotating guard plate 27 unable to rotate in a vertical state, thereby blocking and protecting the front of the lifting plate 3, but also drives the rotating guard plate 27 and the second sliding vertical plate 46 to move together when the horizontal sliding plate 16 is driven by the expansion structure 5, thereby increasing the activity space of the lifting plate 3, and protecting one side of the lifting plate 3 to prevent people from falling from one side of the lifting plate 3;

[0064] The operation steps of the quick-connect structure 6 are as follows: the insert block 31 is driven to move by the middle fixed rod 1 29, at which time the two springs 1 30 are compressed, and when the insert block 31 is inserted along the inside of the placement slot, the inclined surface of the tooth slot 1 will contact and squeeze the tooth slot 2, so that the two baffles 32 are squeezed and slide in the direction away from each other, and the multiple springs 2 34 are compressed until the insert block 31 is completely inserted into the placement slot, and the multiple springs 2 34 rebound to drive the two baffles 32 to reset, so that the tooth slot 1 and the tooth slot 2 are engaged with each other. At this time, the two springs 1 30 have the desire to rebound and drive the insert block 31 to reset, but the reset of the insert block 31 will make the vertical surface of the tooth slot 1 contact the tooth slot 2, thereby making it impossible for the insert block 31 to reset, and thus the connection between the extension block 28 and the rotating guard plate 27 is completed;

[0065] When the horizontal slide plate 16 is at the longest sliding distance, it is necessary to release the connection between the extension block 28 and the rotating guard plate 27, and rotate the rotating guard plate 27 to the horizontal position. At this time, the activity space of the lifting plate 3 is further expanded. The specific steps are: push the push block 36. In the process of pushing the push block 36, the other side of the push block 36 is squeezed with one side of the two squeezing plates 35, so that the two squeezing plates 35 are squeezed and slide in the direction away from each other, thereby driving the two baffles 32 to move in the direction away from each other, so that the tooth groove 1 is disengaged from the tooth groove 2. At this time, the plug block 31 is in a released state, thereby causing the two springs 1 30 to rebound, driving the plug block 31 to reset, thereby releasing the connection between the rotating guard plate 27 and the extension block 28;

[0066] When the rotating guard plate 27 is in a vertical state, the sliding guard plate 41 is slid up, driving the two connecting rods 3 42 and the sliding rod 43 to move upward. When the sliding rod 43 moves up to the highest state, there is a distance between the bottom of the sliding guard plate 41 and the top of the rotating guard plate 27. At this time, the sliding guard plate 41 is rotated along the center of the circle of the sliding rod 43. When the sliding guard plate 41 is rotated to a horizontal state, the sliding guard plate 41 is moved down again, and the two connecting rods 3 42 move down along the two connecting grooves 44. When the connecting rod 3 42 moves to the bottom of the connecting groove 44, the sliding guard plate 41 cannot continue to move downward. At this time, the screw rod near the bottom is rotated so that the screw rod near the bottom is engaged with the thread groove near the bottom, so that the sliding rod 43 is in a fixed state at this position, so that the sliding guard plate 41 is in a stable state at this time, so that the tools required for maintenance can be placed on the top of the sliding guard plate 41 at this time.

[0067] When the rotating guard plate 27 and the sliding guard plate 41 are in a horizontal state, the sliding guard plate 41 is driven to move similarly, so that the sliding guard plate 41 is in a vertical state. At this time, the screw rod near the top is rotated so that the screw rod near the top is threadedly engaged with the thread groove near the top, so that the slide rod 43 cannot move when it is in this position, so that the sliding guard plate 41 is fixed in this position, and then when the rotating guard plate 27 is rotated to a horizontal state, thereby further increasing the activity space of the lifting plate 3, the front and rear parts of the lifting plate 3 can still be protected by the sliding guard plate 41;

[0068] When the rotating guard plate 27 rotates to a horizontal state, thereby further increasing the movable space of the lifting plate 3, the sliding vertical plate 46 is pulled so that one side of the rotating guard plate 27 in a horizontal state is closed by the sliding vertical plate 46, so that when the rotating guard plate 27 is in a horizontal state, its rear part can still provide a protective effect.
