[0040] According to one embodiment of the present application, a mobile working vehicle is provided. The mobile working vehicle is used for maintenance work around a column 6, and a track 5 is arranged along the circumference of the column 6. The mobile working vehicle comprises a moving mechanism 1 arranged on the track 5, the moving mechanism 1 being capable of moving along the track 5 around the column 6, and a maintenance working device 4 arranged on the moving mechanism 1. An extension device 2 is arranged on the moving mechanism 1, and a support assembly 3 is arranged on the extension device 2. The extension end of the extension device 2 is connected with the support assembly 3, and the extension end of the extension device 2 is capable of moving along a first direction, the first direction being parallel to the horizontal plane. The extension end of the extension device 2 has an extended state and a retracted state, and the extension device 2 is capable of driving the support assembly 3 to switch between the extended state and the retracted state, so as to adjust the distance between the support assembly 3 and the column 6. The maintenance working device 4 is arranged on the support assembly 3, and the maintenance working device 4 is used for maintenance of the surface of the column 6.

[0041] As shown in the drawings, the mobile working vehicle is used for driving the maintenance working device 4 to perform maintenance work, repair work and the like around a column 6 structure such as a bridge pier, a circular or polygonal pier column and the like. Figures 1 to 7

[0042] The moving mechanism 1 is a movable trolley. One end of the extension device 2 is connected with the moving mechanism 1, and the other end of the extension device 2 is connected with the support assembly 3. The first direction is a radial direction, and the extension device 2 is actuated to drive the support assembly 3 to move along the radial direction of the column 6 structure. That is, the maintenance working device 4 is installed on the support assembly 3, and the extension device 2 is actuated to drive the support assembly 3 to move away from and close to the column 6 structure, so that the maintenance working device 4 performs work on the column 6 structure.

[0043] In the embodiment of the present application, the column 6 structure is a cylindrical column. A circular track 5 is arranged on the outer periphery of the column 6 structure. The moving mechanism 1 moves along the track 5, that is, the moving mechanism 1 moves along the circumferential direction of the column 6 structure.

[0044] The first direction is a direction from the track 5 to the axis of the column 6 structure, or a direction from the axis of the column 6 structure to the track 5, and the direction is parallel to the horizontal plane. When the distance between the track 5 and the outer wall of the column 6 structure is large, the extension device 2 is expanded to drive the support assembly 3 to move radially, that is, to move in the direction of the axis of the column 6 structure, until the maintenance working device 4 arranged on the support assembly 3 is close to the outer wall of the column 6 structure, or the maintenance working device 4 arranged on the support assembly 3 is in contact with the outer wall of the column 6 structure, and work can be started.

[0045] ​When the distance between the track 5 and the outer wall of the column 6 structure is small, the telescopic device 2 is retracted, driving the support assembly 3 to move radially, that is, driving the support assembly 3 to move away from the axis of the column 6 structure, until the support assembly 3 drives the maintenance operation device 4 away from the outer wall of the column 6 structure.

[0046] Of course, the column in the embodiment of the present application is not limited to the structure described above, and those skilled in the art can set it according to actual needs. For example, the column 6 structure can also be a prism, an elliptical column, etc.

[0047] In the embodiment of the present application, the moving mechanism 1 is arranged on the track 5, which can be a ring structure centered on the column 6, or a spiral track 5 rising from the center of the column 6. The moving mechanism 1 moves along the track 5 around the column 6. The moving mechanism 1 on the track 5 has a telescopic device 2, which is switched between an expanded state and a retracted state, so that the distance between the support assembly 3 and the column 6 can be adjusted, thereby driving the maintenance operation device 4 on the support assembly 3 to adapt to column 6 structures of different diameters, effectively improving the adaptability of the mobile operation vehicle.

[0048] In addition, by pushing the support assembly 3 in the first direction through the telescopic device 2, the abutting force between the support assembly 3 and the column 6 structure can be strengthened, so that the support assembly 3 is tightly attached to the surface of the column 6 structure, which not only improves the operation effect, but also improves the stability of the telescopic device 2 during operation.

[0049] As shown in Figure 1 and Figure 5 The support assembly 3 is a support frame for carrying the maintenance operation device 4. The maintenance operation device 4 is arranged on the support assembly 3.

[0050] The connecting pieces 22 are arranged on opposite sides of the support frame, and the telescopic device 2 is connected to the support frame through the connecting pieces 22, so that when the telescopic device 2 expands and retracts, the support frame is driven away from and close to the moving mechanism 1 through the connecting pieces 22, thereby adjusting the distance between the maintenance operation device 4 and the column 6 structure, adapting to column 6 structures of different diameters, or expanding and retracting according to the surface curvature of the column 6 structure to make the maintenance operation device 4 fit the surface of the column 6 structure.

[0051] In one example, the support assembly 3 comprises a connecting frame 31, opposite ends of the connecting frame 31 are connected with connecting plates 32, the opposite connecting plates 32 and the connecting frame 31 enclose to form a mounting space 33 for loading the maintenance device 4, the connecting plates 32 are detachably connected with the maintenance device 4, and the side of the connecting plates 32 away from the maintenance device 4 is connected with the telescopic device 2, and the telescopic device 2 drives the connecting frame 31 to drive the maintenance device 4 to approach or move away from the column 6.

[0052] As shown in Figure 1 and Figure 5 , the connecting frame 31 is plate-shaped. The opposite ends of the connecting frame 31 are respectively provided with connecting plates 32, and the two connecting plates 32 are connected with the connecting frame 31 to form a support frame, and the support frame has a semi-enclosed mounting space 33. The maintenance device 4 is arranged in the mounting space 33, that is, the left and right sides of the maintenance device 4 are respectively detachably connected with the connecting plates 32, so that the maintenance device 4 is connected with the telescopic device 2 through the connecting plates 32.

[0053] The telescopic device 2 is connected with the support assembly 3, and the telescopic device 2 can drive the support assembly 3 to switch between the extended state and the retracted state, so as to drive the maintenance device 4 on the support assembly 3 to approach or move away from the column 6, thereby adjusting the distance between the maintenance device 4 and the column 6, adapting the distance between the column 6 structure such as a pier column of different diameter sizes and the track 5, and effectively improving the adaptability of the mobile working vehicle.

[0054] In one example, the support assembly 3 further comprises a sliding member 34, the sliding member 34 is arranged on the side of the connecting plate 32 away from the maintenance device 4, the sliding member 34 is connected with the telescopic device 2, and the connecting frame 31 is slidingly connected with the sliding member 34 along the first direction.

[0055] As shown in Figure 1 and Figure 5 , the outer sides of the two connecting plates 32 are respectively provided with sliding members 34, and the sliding members 34 are slidingly connected with the connecting plates 32.

[0056] The opposite sides of the sliding member 34 are respectively connected with the connecting plate 32 and the telescopic device 2, and the sliding member 34 is driven to act by the telescopic device 2, so that the connecting plate 32 can switch between the extended state and the retracted state to adapt to the column 6 structure of different diameter sizes.

[0057] The sliding connection of the sliding member 34 and the connecting plate 32 enables the maintenance operation device 4 located in the installation space 33 to form a buffer in the radial direction of the column 6 structure such as a pier column when the maintenance operation device 4 contacts the column 6 structure, so as to reduce the impact force when the operation device contacts the column 6 structure, and reduce the collision damage to the maintenance operation device 4.

[0058] In one example, the support assembly 3 further comprises an elastic member 35, which is capable of elastic deformation in the sliding direction of the sliding member 34, one end of the elastic member 35 is connected with the sliding member 34, and the other end of the elastic member 35 is connected with the connecting plate 32; wherein the extension direction of the sliding member 34 is the same as the first direction.

[0059] As shown in Figures 1 to 9 , the elastic member 35 is a spring. The extension direction of the elastic member 35 is the same as the first direction, one end of the elastic member 35 is fixed to the sliding member 34, and the other end of the elastic member 35 is a free end and is capable of elastic deformation in the first direction.

[0060] When the connecting plate 32 moves in the first direction through the sliding member 34, the free end of the elastic member 35 is fixedly connected with the connecting plate 32, so that the elastic member 35 is elastically deformed. For example, during the unfolding process of the telescopic device 2, the inertia causes the maintenance operation device 4 to generate a force away from the moving mechanism 1, at this time, the connecting plate 32 slides along the slide rail 341 away from the moving mechanism 1, and the elastic member 35 is in a stretched state. When the maintenance operation device 4 contacts the outer wall of the column 6 structure such as a pier column, or the elastic member 35 is stretched to a certain extent, a reverse force is generated, that is, the maintenance operation device 4 generates a force sliding towards the moving mechanism 1, at this time, the free end of the elastic member 35 drives the connecting plate 32 to slide along the slide rail 341, so that the support assembly 3 drives the maintenance operation device 4 to slide towards the moving mechanism 1, thereby achieving buffering. By providing the support assembly 3, not only can the maintenance operation device 4 be provided with a buffering effect during sliding, but also the maintenance operation device 4 can work on the column 6 structure such as a pier column having a protrusion or a groove on the surface during work, thereby effectively improving the work precision.

[0061] The elastic member 35 can also be a spring, an elastic sheet, or a gas support, etc.

[0062] In one example, the sliding member 34 comprises a sliding rail 341 and a sliding plate 342; the sliding rail 341 is arranged on the side of the connecting plate 32 away from the maintenance working device 4; the side of the sliding plate 342 corresponding to the sliding rail 341 is provided with a sliding block, the sliding block is embedded in the sliding rail 341, and the sliding plate 342 can move along the extension direction of the sliding rail 341.

[0063] As shown in Figures 1 to 9 , two sliding plates 342 are provided with sliding rails 341, and the positions of the sliding rails 341 on the two sliding plates 342 correspond to each other. Two sliding rails 341 are arranged on each sliding plate 342, the two sliding rails 341 are arranged in parallel in the up-down direction, and the elastic member 35 is arranged between the two sliding rails 341.

[0064] The side of the connecting plate 32 away from the maintenance working device 4 is connected with the free end of the elastic member 35, and the connecting member 22 can move along the extension direction of the sliding rail 341. For example, a matching member is arranged on the side of the connecting member 22 close to the sliding plate 342, and the connecting member 22 is moved along the sliding rail 341 by the matching member, so as to drive the connecting plate 32 to slide along the sliding rail 341.

[0065] Through the sliding rail 341 and the elastic member 35, not only the sliding connection between the connecting plate 32 and the sliding plate 342 can be realized, but also the buffering effect of the maintenance working device 4 during sliding can be provided, and the maintenance working device 4 can work on the column 6 structure with protrusions or grooves on the surface during working, so as to effectively improve the working precision.

[0066] In one example, the side of the maintenance working device 4 close to the column 6 is provided with a contact roller, when the extension end of the extension device 2 is in the extended state, the outer wall of the contact roller abuts against the outer wall of the column 6, and the contact roller rotates along the circumferential direction of the column 6.

[0067] As shown in Figures 1 to 7 , the moving mechanism 1 is provided with the maintenance working device 4. The maintenance working device 4 comprises a working support, the working support is arranged in the mounting space 33, and the two opposite sides of the working support are respectively connected with the connecting plate 32. The distance between the support assembly 3 and the outer wall of the column 6 is adjusted by the extension device 2, and then the distance between the maintenance working device 4 and the outer wall of the column 6 is adjusted.

[0068] The side of the operation support close to the outer wall of the column 6 is provided with a contact roller, the contact roller is rotationally arranged on the operation support, and the axis of the contact roller is parallel to the axis of the column 6. When the telescopic device is in the extended state, the outer wall of the contact roller is in contact with the surface of the column 6. When the moving mechanism 1 moves along the track 5, the contact roller can provide support, thereby keeping the distance between the maintenance operation device 4 and the surface of the column 6 constant. Two or more contact rollers are arranged circumferentially along the column 6, thereby ensuring that the maintenance operation device 4 is always perpendicular to the surface of the column 6, and further ensuring the maintenance quality. The plurality of contact rollers cooperate with the support assembly to provide floating support in the case of uneven surface of the column 6, and ensure stable operation of the mobile operation vehicle.

[0069] Of course, the contact roller in the embodiment of the present application is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the contact roller can also be a universal wheel, which can convert the rotation axis direction when the mobile operation vehicle moves horizontally around and moves up and down on the track 5, and realize adaptive motion.

[0070] The maintenance operation device 4 includes a telescopic rod and a maintenance operation piece. One end of the telescopic rod is arranged on the moving mechanism 1, and the maintenance operation piece is arranged at the other end of the telescopic rod. By arranging the maintenance operation piece, the surface of the pier column can be maintained.

[0071] Of course, the maintenance operation device 4 in the embodiment of the present application is not limited to the above structure, and those skilled in the art can set it according to actual needs. For example, the maintenance operation device 4 can be arranged on the support assembly 3.

[0072] The maintenance operation device 4 can also include a spraying or grinding maintenance operation device. By arranging the spraying / grinding device, the surface of the pier column is maintained to improve the driving accuracy of the telescopic device, and further improve the moving accuracy of the maintenance operation device 4.

[0073] By arranging the telescopic rod, not only can the maintenance operation device 4 be avoided to avoid conflict between the maintenance operation device 4 during operation, but also the height position of the maintenance operation device 4 can be adjusted according to the column 6 structure of different height pier columns, and the maintenance of the column 6 structure of different sizes of pier columns can be adapted, thereby effectively improving the adaptability.

[0074] In one example, the telescopic device 2 includes a first driving piece 21 and a connecting piece 22, the connecting piece 22 is arranged at the telescopic end of the first driving piece 21, and the connecting piece 22 is connected with the sliding piece 34; wherein the opposite sides of the support assembly 3 are respectively connected with the telescopic device 2.

[0075] As Figures 1 to 9As shown, the telescopic device 2 is arranged on the moving mechanism 1, and the telescopic end of the telescopic device 2 is connected with the connecting piece 22, the connecting piece 22 is in a sheet shape, one side of the connecting piece 22 is connected with the telescopic device 2, and one end of the connecting piece 22 is connected with the sliding piece 34.

[0076] When the telescopic device 2 is in the extended state, the support assembly 3 is away from the moving mechanism 1, that is, in the state that the distance between the column body 6 structure and the moving mechanism 1 is large, the telescopic device 2 can drive the support assembly 3 to approach the column body 6 structure. When the telescopic device 2 is in the retracted state, the support assembly 3 is close to the moving mechanism 1, that is, in the state that the distance between the column body 6 structure and the moving mechanism 1 is small, the telescopic device 2 can drive the support assembly 3 to move towards the moving mechanism 1, so as to adjust the distance between the support assembly 3 and the column body 6 structure, and improve the adaptability of the mobile operation vehicle through the telescopic device 2.

[0077] The telescopic device 2 comprises a first driving piece 21, which can provide power to the support assembly 3 to drive the telescopic assembly to approach and move away from the moving mechanism 1.

[0078] The first direction is the direction of moving from the moving mechanism 1 to the column body 6 structure, or the direction of moving from the column body 6 structure to the moving mechanism 1. That is, for example, the column body is in a cylindrical shape, and an annular track 5 is arranged around the outer periphery of the cylindrical column body, and the mobile operation vehicle can move around the column body along the track 5. The first driving piece 21 can drive the support assembly 3 to move in the radial direction of the track 5, so as to drive the maintenance operation device 4 to approach and move away from the column body, and through the telescopic assembly, the support assembly 3 drives the maintenance operation device 4 to move, so as to adjust the distance between the maintenance operation device 4 and the column body 6 structure, and make the mobile operation vehicle adapt to column bodies with different diameters.

[0079] The telescopic device 2 is arranged on the moving mechanism 1, and the telescopic end of the telescopic device 2 is connected with the connecting piece 22, the connecting piece 22 is in a sheet shape, one side of the connecting piece 22 is connected with the telescopic device 2, and one end of the connecting piece 22 is connected with the sliding piece 34.

[0080] As shown in the drawings, Figures 1 to 7 In the embodiment of the present application, the telescopic device 2 is a linear push rod. Two linear push rods are arranged on the moving mechanism 1, and the two linear push rods are arranged at the left and right ends of the moving mechanism 1.

[0081] The driving end of the linear push rod is connected with the left and right sides of the support assembly 3 through the connecting piece 22. The linear push rod has an extended state and a retracted state. When the linear push rod is in the extended state, the support assembly 3 is away from the moving mechanism 1. When the linear push rod is in the retracted state, the support assembly 3 is close to the moving mechanism 1. That is, the linear push rod can push the support assembly 3 to move horizontally to adapt to different sizes of the track 5 and the column body 6 structure, effectively improving the adaptability of the mobile working vehicle.

[0082] The opposite sides of the support assembly 3 are respectively provided with connecting parts. The driving end of the linear push rod is connected with the connecting parts to drive the support assembly 3 to move.

[0083] Using linear push rods with different strokes can achieve a larger range of movement of the support assembly 3, improving the adaptability of the mobile working vehicle.

[0084] In one example, the moving mechanism 1 includes a housing 11 and a moving assembly 12, the telescopic device 2 and the moving assembly 12 are arranged at opposite ends of the housing 11, the moving assembly 12 is adapted to the track 5, and the moving assembly 12 is used to drive the housing 11 to move.

[0085] As shown in Figures 1 to 7 The housing 11 is a rectangular box. The housing 11 is provided with a door body. The door body is arranged on the rectangular box to facilitate storing articles or electronic components required by the mobile working vehicle in the housing 11, and the door body is arranged on the housing 11 to facilitate maintenance of the equipment in the housing 11.

[0086] The telescopic device 2 is arranged at the top of the housing 11, and the moving assembly 12 is arranged at the bottom of the housing 11. The moving assembly 12 cooperates with the track 5 to enable the housing 11 to move around the column body 6 structure along the track 5, so as to drive the telescopic device 2 and the support assembly 3 to work on the column body 6 structure.

[0087] In one example, the moving assembly 12 includes a second driving member and a clamping wheel 121. The second driving member is arranged in the housing 11. The clamping wheel 121 is connected with the second driving member. A plurality of clamping wheels 121 are arranged on the side of the housing 11 close to the track 5. Two clamping wheels 121 are arranged on opposite sides of the track 5. The two clamping wheels 121 are respectively in rolling connection with the track 5. The second driving member can drive at least one clamping wheel 121 to rotate.

[0088] As shown in Figures 1 to 7As shown, the second driving member is arranged in the housing 11. By arranging the second driving member in the housing 11, the weight of the housing 11 can be effectively increased, thereby improving the stability of the moving mechanism 1. In addition, the stability of the device can be maintained by increasing the weight at the rear end of the housing 11.

[0089] As shown, the moving assembly 12 is arranged at the bottom of the housing 11, and the moving assembly 12 is in rolling cooperation with the track 5, thereby driving the housing 11 to move along the track 5. Figures 1 to 7

[0090] The second driving member is a driving motor. The driving motor is arranged in the housing 11, and the driving end of the driving motor extends downward and out of the housing 11 to be connected with the clamping wheel 121.

[0091] As shown, the number of clamping wheels 121 is four.
