[0056] This invention provides a mobile frame turning machine for clamping, lifting, and turning heavy and large frames such as bogies, to facilitate maintenance and inspection and improve maintenance and inspection efficiency.

[0057] like Figure 1 As shown, taking frame 500 as an example, two mobile frame flipping machines form a group, respectively used to clamp both ends of frame 500, realizing the lifting and flipping operations of frame 500. The mobile frame flipping machine provided in this embodiment includes a mobile trolley 100, a frame 200, a lifting assembly 300, and a clamping assembly 400. The mobile trolley 100 can move horizontally to achieve mutual separation or proximity between the two mobile trolleys 100; the bottom end of the frame 200 is fixed on the mobile trolley 100 and can move with the mobile trolley 100 to achieve mutual separation or proximity between the two frames 200; the lifting assembly 300 is set on the frame 200, and the two lifting assemblies 300 can be synchronously lifted and lowered along the height direction of the two frames 200 respectively; the clamping assembly 400 is rotatably connected to the lifting assembly 300 and can be lifted and lowered with the lifting assembly 300, and the two clamping assemblies 400 can clamp both ends of the frame 500 respectively.

[0058] The mobile frame tilting machine of the present invention, by respectively mounting two frames 200 on two mobile trolleys 100, allows the two frames 200 to be moved horizontally away from or close together by the mobile trolleys 100. This enables the spacing between the two frames 200 to be adjusted according to the length of the frame 500, making it suitable for frames 500 of different sizes and providing good versatility. By installing synchronously lifting components 300 on the two frames 200, synchronous lifting of both ends of the frame 200 can be achieved, ensuring stable lifting even for heavy frames 500, facilitating inspection and testing, and improving inspection and testing efficiency. By setting a clamp assembly 400 on the lifting assembly 300, the frame 500 fixed on the two clamp assemblies 400 can be raised to a safe height with the clamp assembly 400 and then flipped relative to the lifting assembly 300. After flipping, it can be lowered to a specified height for inspection and testing. This facilitates the control and operation of the frame 500 at different flipping angles, thereby realizing the flipping inspection and testing of the frame 500, reducing the labor intensity and workload of operators, and improving maintenance efficiency.

[0059] Optionally, the mobile trolley 100 includes a base 101, a support plate 102, and a horizontal drive mechanism 103, such as... Figure 1 and Figure 2As shown, the base 101 is fixedly arranged on the ground foundation, the base 101 is provided with a linear guide rail 104, and the two linear guide rails 104 on the two moving trolleys 100 are arranged in line. The support plate 102 is slidingly connected to the linear guide rail 104, and the bottom end of the rack 200 is detachably connected above the support plate 102. The horizontal driving mechanism 103 is configured to drive the support plate 102 to slide along the linear guide rail 104 to drive the movement of the rack 200. Among them, the base 101 selects a compartment structure, the linear guide rail 104, the support plate 102 and the horizontal driving mechanism 103 are all arranged inside the base 101 and fixed, the base 101 is poured with concrete and fixed and embedded with bolts, the linear guide rail 104 can be connected with the embedded bolts to realize fixation. The two sides of the linear rail 104 can be selected to be provided with guide rails to ensure the linear walking direction of the support plate 102. The linear rail 104 is flush with the ground after installation, a safety cover is arranged above the base 101 to protect the linear rail 104 and the horizontal driving mechanism 103, and a foot platform can be formed above the base 101 to facilitate the movement of the on-site operator. In some embodiments, the horizontal driving mechanism 103 is a hydraulic cylinder, and the two horizontal driving mechanisms 103 of the two moving trolleys 100 are connected through a hydraulic pipeline to realize synchronous driving movement of the two support plates 102. Of course, according to the actual operation needs, the two horizontal driving mechanisms 103 can also drive the two support plates 102 to move individually, to adjust the distance between the two racks 200, and then adjust the distance between the two chuck assemblies 400, so as to clamp and fix the frame 500. The sliding connection between the support plate 102 and the linear guide rail 104 is a sliding block connection, such as arranging a sliding block below the support plate 102 to cooperate with the linear guide rail 104 to realize sliding connection. It should be noted that when installing the base 101, attention should be paid to the consistency of the two linear guide rails 104 to ensure the consistency of the two racks 200 in the horizontal direction.

[0060] Optionally, the lifting assembly 300 comprises a lifting driving mechanism 301, a lead screw 302, a lifting nut 303 and a lifting plate 304. The lifting driving mechanism 301 is arranged at the top end of the rack 200. The rack 200 has a hollow cavity 201 along the height direction and a sliding groove 202 which is in communication with the hollow cavity 201 and the outer wall of the rack 200. The lead screw 302 is arranged in the hollow cavity 201. The bottom end of the lead screw 302 is rotatably connected to the bottom end of the rack 200. The top end of the lead screw 302 is connected to the output end of the lifting driving mechanism 301. The lifting driving mechanism 301 can drive the lead screw 302 to rotate. The lifting nut 303 is threadedly connected to the lead screw 302. The lifting nut 303 is configured to convert the rotation of the lead screw 302 into the lifting movement of the lifting nut 303. The horizontal support rod 305 is connected to the lifting nut 303. The end of the horizontal support rod 305 away from the lifting nut 303 is arranged in the sliding groove 202. The horizontal support rod 305 abuts against the inner wall of the sliding groove 202 to limit the rotation of the lifting nut 303. The lifting plate 304 is arranged outside the rack 200 and is connected to the horizontal support rod 305. The horizontal support rod 305 can drive the lifting plate 304 to lift.

[0061] As Figures 2-5 , the rack 200 is a square steel framework with a rectangular cross section. A long sliding groove 202 is arranged on one side of the rack 200 along the height direction (also the lifting direction). The hollow cavity 201 extends through the long axis direction of the framework 200. The length of the sliding groove 202 along the long axis direction of the rack 200 is greater than the distance that the framework 500 needs to lift. The lead screw 302 has a T-shaped external thread. The lead screw 302 is threadedly connected to the lifting nut 303. When the lifting driving mechanism 301 drives the lead screw 302 to rotate, the lifting nut 303 realizes lifting movement, thereby realizing the conversion of rotation and lifting movement. The lifting driving mechanism 301 adopts a combination of a driving motor and a speed reducer. The speed reducer adopts a turbine speed reducer with a brake. The driving force is large and has a self-locking function. The T-shaped thread on the lead screw 302 realizes double locking. It should be noted that the diameter of the lead screw 302 is not less than 80 mm due to the large weight of the framework 500. In this embodiment, the horizontal support rod 305 has two parts which are symmetrically arranged on the two sides of the lifting nut 303. The two horizontal support rods 305 pass through the sliding groove 202 from the hollow cavity 201 and are connected to the lifting plate 304. The width of the two horizontal support rods 305 is equal to the width of the sliding groove 202. The outer sides of the two horizontal support rods 305 which are away from each other can abut against the inner walls of the slots of the sliding groove 202, thereby limiting the rotation of the lifting nut 303. In some embodiments, a dust cover is arranged on the outer side of the lead screw 302. The two ends of the dust cover are connected to the lifting nut 303 and the top end of the rack 200, or are connected to the protection nut 306 and the bottom end of the rack 200.

[0062] Optionally, the lifting assembly 300 also includes a protective nut 306, which is threaded to the lead screw 302. The protective nut 306 and the lifting nut 303 are spaced apart and connected by a connecting plate 307 to achieve synchronous lifting.

[0063] like Figure 5 As shown, in this embodiment, the protective nut 306 is threaded onto the lead screw 302 and located below it. This ensures that the lead screw 302 remains threadedly connected even if the lifting nut 303 fails or malfunctions, reducing or preventing accidents. A connecting plate 307 connects to the outer walls of the protective nut 306 and the lifting nut 303, facilitating synchronous lifting and lowering of both nuts and increasing the safety of the lifting nut 303. Multiple connecting plates 307 are provided, spaced apart around the outer periphery of the protective nut 306 and the lifting nut 303. The connecting plates 307 are made of steel plates and connected to the protective nut 306 and the lifting nut 303 by bolts, facilitating assembly and disassembly. The lifting nut 303 is bolted to the horizontal support rod 305.

[0064] Optionally, the lifting plate 304 is arranged around the outer peripheral wall of the frame 200. The outer peripheral wall of the frame 200 is provided with multiple parallel lifting rails 203. The lifting plate 304 is provided with a guide component 308, which is slidably connected to the lifting rails 203.

[0065] like Figure 2 As shown, the frame 200 has a rectangular cross-section, and the lifting plate 304 is a rectangular frame box structure. The lifting plate 304 is sleeved on the outside of the frame 200, and the guide assembly 308 is clamped between the lifting plate 304 and the frame 200 to reduce the sliding friction between them. Specifically, the lifting rail 203 is arranged around the four sides of the frame 200 and protrudes from the surface of the side of the frame 200. In this embodiment, since the frame 500 has a large self-weight, a counterweight block 309 is provided on the lifting plate 304 at a position opposite to the clamp assembly 400 to balance the weight of the frame 500 and improve the smoothness of the lifting and sliding of the lifting plate 304.

[0066] like Figure 2 In the illustrated embodiment, the lifting plate 304 is provided with four sets of mounting holes 3041, each set of mounting holes 3041 being arranged opposite each other for mounting the guide assembly 308. Each side of the lifting plate 304 is provided with four assembly holes 3042.

[0067] like Figure 6As shown, the guide assembly 308 includes a guide shaft 3081, a guide wheel 3082 and a gland 3084. The guide shaft 3081 is an optical axis, one end has a head, the other end can pass through two installation holes 3041 in opposite positions in sequence, and is fixedly connected with the guide shaft 3081 through the gland 3084, so as to realize the installation and fixation of the guide shaft 3081. The guide shaft 3081 is rotatably connected with the installation hole 3041, that is, the outer diameter of the guide shaft 3081 is slightly smaller than the inner diameter of the installation hole 3041. The gland 3084 is connected with the end of the guide shaft 3081 by bolts. The guide wheel 3082 is provided with two and is arranged on the guide shaft 3081 in a spaced manner. The guide wheel 3082 is rotatably connected with the guide shaft 3081, for example, the guide wheel 3082 is connected with the guide shaft 3081 through a bearing. The positions of the two guide wheels 3082 correspond to the positions of the assembly holes 3042 on the lifting plate 304. The guide wheel 3082 can roll on the circumferentially arranged lifting rail 203 of the frame 500, so that the lifting plate 304 and the frame 200 form a rolling friction, the friction is small, and the lifting control is facilitated. After the guide wheel 3082 is installed, it is rotatably connected with the lifting rail 203 and can also be partially arranged in the assembly hole 3042. The assembly hole 3042 can limit the guide wheel 3082, so as to avoid the problem of derailment when the lifting is stuck or inclined. Figure 2 It can be known that in the embodiment, two upper and lower guide assemblies 308 are arranged on the lifting plate 304 on both sides of the sliding groove 202, and the sliding groove 202 and the lifting plate 304 in opposite positions are also provided with two upper and lower guide assemblies 308. In this way, the vertical lifting of the lifting plate 304 can be ensured, the lifting quality is improved, and the lifting movement operation of the frame 500 with large mass and volume is suitable. In order to further axially position the two spaced guide wheels 3082, Figure 6 The guide assembly 308 further includes a positioning sleeve 3083, which is sleeved on the guide shaft 3081 and located between the two guide wheels 3082 and between the guide wheel 3082 and the lifting plate 304, so as to axially position the guide wheel 3082. Further, the positioning sleeve 3083 is fixedly connected with the guide shaft 3081 by screws or pins.

[0068] Optionally, the chuck assembly 400 includes a U-shaped base 401, an upper clamp 402 and a lower clamp 403. The center of the middle beam 4011 of the U-shaped base 401 is rotatably connected with the lifting plate 304. The upper clamp 402 is arranged on the upper free end 4012 of the U-shaped base 401. The upper clamp 402 is movably connected with the upper free end 4012. The upper clamp 402 can adaptively adjust the clamping angle according to the frame 500. The lower clamp 403 is arranged on the lower free end 4012 of the U-shaped base 401. The lower clamp 403 is rotatably connected with the lower free end 4012. The lower clamp 403 can adaptively adjust the clamping angle according to the frame 500.

[0069] As Figure 3 shown, the middle beam 4011 of the U-shaped base 401 is fixedly connected to one end of the rotating shaft 404 away from the free end 4012, and the other end of the rotating shaft 404 is rotatably connected to the lifting plate 304. When the U-shaped base 401 is rotated, the U-shaped base 401 drives the frame 500 to rotate to realize overturning. By limiting and controlling the rotation of the rotating shaft 404, the frame 500 can be rotated at any angle to facilitate maintenance and detection.

[0070] Optionally, the upper clamp 402 comprises a clamping cylinder 4021 and an upper clamp plate 4022. The clamping cylinder 4021 is fixed to one of the free ends 4012, and the output end of the clamping cylinder 4021 is arranged towards the lower clamp 403. The output end of the clamping cylinder 4021 is provided with a ball head 40211. The upper clamp plate 4022 is provided with a ball socket 40221, and the ball socket 40221 is installed in cooperation with the ball head 40211 to movably connect the upper clamp plate 4022. The stress surface of the upper clamp plate 4022 is provided with an anti-skid layer 4023.

[0071] As Figure 7 shown, the clamping cylinder 4021 is preferably a hydraulic cylinder. The clamping cylinders 4021 of the two clamp head assemblies 400 can be connected through a hydraulic pipeline to realize synchronous driving. The output end of the clamping cylinder 4021 is arranged towards the lower clamp 403 to facilitate adjustment of the distance between the upper clamp 402 and the lower clamp 403 to adapt to the clamping of frames 500 of different sizes. The cooperation between the ball head 40211 and the ball socket 40221 allows the upper clamp plate 4022 of the upper clamp 402 to have adaptive rotation within a certain range when the frame 500 is placed between the upper clamp 402 and the lower clamp 403, which facilitates the assembly of the initial position of the frame 500. The anti-skid layer 4023 is arranged on the stress surface of the upper clamp plate 4022. As Figure 2 shown, the upper clamp plate 4022 has a U-shaped cross section, and the end faces of the two end portions are stress surfaces. The anti-skid layers 4023 are arranged on the two stress surfaces respectively. The anti-skid layers 4023 are made of rubber material, and the surface of the anti-skid layer 4023 has grooves to increase the friction.

[0072] Optionally, the lower clamp 403 comprises an optical shaft 4031 and a lower clamp plate 4032. The optical shaft 4031 is rotatably connected to the lower free end 4012 in the horizontal direction. The lower clamp plate 4032 is arranged on the optical shaft 4031 and fixedly connected.
