DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0031] First embodiment

[0032] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 ,in, Figure 1 This is a schematic diagram of the leveling mechanism structure provided by the utility model; Figure 2 A schematic diagram of the leveling mechanism and equipment installation structure provided by the utility model; Figure 3 This is a schematic diagram of the welding structure of the mounting base provided by the utility model;

An adjustment device for a heavy-load leveling mechanism for a rail engineering vehicle includes a jack 12, the bottom of which is rotatably connected to a rotating seat 11, the bottom of which is fixedly mounted to a base plate 1, the side of which is fixedly mounted to a side of the base plate 1, the top of which is fixedly mounted to a threaded sleeve 21, the inner side of which is threadedly connected to a screw rod 22, the top of which is fixedly mounted to a rotating handle 23, and the top of which is rotatably connected to a top plate 24.

[0034] A positioning plate 41 is fixedly mounted on the top of the outer side of the threaded sleeve 21 , and a positioning groove 41 is formed inside one end of the positioning plate 41 .

[0035] A limiting plate 3 is fixedly mounted on the bottom of the top plate 24 , a first tooth plate 31 is fixedly mounted on one side of the limiting plate 3 , and two sides of the limiting plate 3 are respectively attached to two sides of the inner side of the positioning groove 41 .

[0036] By sliding the limit plate 3 on the inner side of the positioning groove 41, the limit plate 3 can limit the top plate 24 during use, preventing the top plate 24 from rotating during the lifting process, thereby increasing the stability of the top plate 24 when moving.

[0037] A limiting assembly 5 is fixedly installed inside one end of the positioning plate 4. The limiting assembly 5 includes a mounting frame 51, a threaded rod 52, a rotating plate 53, a moving plate 54, a sliding rod 55, a baffle 56, a spring 57, a pushing plate 58 and a second tooth plate 59.

[0038] The mounting frame 51 is fixedly mounted inside one end of the positioning plate 41, the threaded rod 52 is threadedly connected to the inside of one side of the mounting frame 51, the rotating plate 53 is fixedly mounted on one end of the threaded rod 52, the movable plate 54 is rotatably connected to the other end of the threaded rod 52, the sliding rod 55 is slidably connected to the top and bottom of the movable plate 54 respectively, the spring 57 is sleeved on the outer side surface of the sliding rod 55, the pushing plate 58 is fixedly mounted on one end of the sliding rod 55, and the second tooth plate 59 is fixedly mounted on one side of the pushing plate 58.

[0039] Before adjusting the height of the top plate 24, the user first rotates the rotating plate 53 so that the rotating plate 53 drives the threaded rod 52 to be threadedly connected inside the mounting frame 51, thereby driving the movable plate 54 and the pushing plate 58 to move toward one side of the first tooth plate 31, so that the first tooth plate 31 is engaged with the second tooth plate 59. When the top plate 24 moves upward, it drives the limiting plate 3 and the first tooth plate 31 to move upward. At this time, the pushing plate 58 is pushed by the spring 57, so that the second tooth plate 59 and the first tooth plate 31 are always engaged, thereby limiting the top plate 24 and increasing the stability of the manufacturing process.

[0040] When disassembly is required later, the second tooth plate 59 must first be adjusted away from the first tooth plate 31 .

[0041] The outer side surfaces of the movable plate 54 and the pushing plate 58 are both slidably connected to the inner side surface of the mounting frame 51, the baffle 56 is fixedly mounted on the other end of the slide rod 55, the spring 57 is arranged between the pushing plate 58 and the movable plate 54, and the second tooth plate 59 and the first tooth plate 31 are arranged opposite to each other.

[0042] When in use, the base plate 1 is placed on the vehicle frame, the top of the jack 12 and the cylinder mounting seat are installed, and then the jack 12 is extended to adjust the base frame. After adjusting to a suitable angle, the user rotates the handle 23 so that the handle 23 drives the screw rod 22 to be threadedly connected to the inner side of the threaded sleeve 21, so that the top of the screw rod 22 drives the top plate 24 to move upward, so that the top of the top plate 24 abuts against the bottom of the leveling base frame, thereby supporting the leveling base frame and preventing the jack 12 from being under pressure for a long time.

[0043] When using the adjustment device to connect the heavy-load leveling mechanism of the railway engineering vehicle, the following steps are included:

[0044] S1. During the manufacturing process of the leveling chassis, ensure the flatness of the plane where the mounting seat is located;

[0045] S2. Use a steel pipe or round rod (whose outer diameter is 1mm smaller than the mounting seat sleeve and whose length exceeds the mounting seat welding position) to penetrate the mounting seat sleeve, and then place it on the position of the leveling base for welding. Ensure that the coaxiality of the mounting seat sleeve hole is no more than 1mm after welding.

[0046] S3. Use a temporary pin (1mm smaller than the inner diameter of the bushing) to connect the mounting base to the frame connection base, then place it on the frame according to the drawing requirements. Use the adjustment device near the leveling cylinder mounting base to adjust the leveling chassis to the upper plane level.

[0047] S4. Use the counterweight to preload the leveling mechanism to a fully loaded state according to the mass distribution of the equipment when it is installed, and then weld the frame connection seat and the frame weld;

[0048] S5. Use the adjustment equipment to lift the leveling chassis, remove the temporary pin and install the rotating pin. After the replacement is completed, remove the counterweight.

[0049] S6. After the counterweight is removed, the frame deflection is restored, and the concentricity of the three pins connecting the frame connection seat and the leveling frame becomes larger. In the free state, the leveling mechanism is stuck and cannot rotate. After the equipment is installed and the vehicle reaches the ready state, the frame deflection returns to the state at the time of welding, the concentricity of the pins is restored, and the leveling frame resumes rotation.

[0050] Compared with related technologies, the adjustment device of the heavy-load leveling mechanism of a rail engineering vehicle provided by the present invention has the following beneficial effects:

[0051] By strictly ensuring the coaxiality of the mounting seat sleeve during the leveling mechanism manufacturing process, then using a temporary pin to connect the mounting seat to the frame connecting seat and place it on the frame according to the drawing, using adjustment equipment to level the leveling frame near the leveling cylinder mounting seat, then using a counterweight block to preload according to the mass distribution of the equipment tooling when the leveling mechanism is fully loaded, and then welding the welds between the frame connecting seat and the frame. After that, the leveling frame is lifted up to remove the temporary pin, and the rotating pin is installed and the counterweight is removed. This effectively solves the problem of large frame deflection changes under gravity due to the heavy weight of the leveling mechanism equipment and materials, changes in the position of the three mounting seats and the pins, and excessive coaxiality of the pins, which causes the leveling mechanism to get stuck or even unable to rotate. At the same time, it overcomes the difficulties of complex calculation of the deformation of the connection between the leveling mechanism and the frame, difficult to predict the deformation, and inability to ensure the concentricity of the pins in the ready state through conventional methods such as reserved height difference or prefabricated reverse deformation. This ensures the normal use and smooth rotation of the leveling mechanism in the ready state, and the on-site operation is simple and easy.

[0052] Second embodiment

[0053] Please refer to Figure 10 、 Figure 11 Based on the first embodiment of this application, which provides an adjustment device for a heavy-load leveling mechanism for a railway engineering vehicle, the second embodiment of this application provides another adjustment device for a heavy-load leveling mechanism for a railway engineering vehicle. The second embodiment is merely a preferred embodiment of the first embodiment, and implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0054] Specifically, the difference of the adjustment device of the heavy-load leveling mechanism of a rail engineering vehicle provided in the second embodiment of the present application is that, in the adjustment device of the heavy-load leveling mechanism of a rail engineering vehicle, a mounting plate 6 is provided on the top of the top plate 24, and a rubber pad 61 is fixedly installed on the top of the mounting plate 6.

[0055] Positioning rods 62 are fixedly mounted on both ends of the bottom of the mounting plate 6 , and the positioning rods 62 are arranged inside the top plate 24 .

[0056] A sliding groove 63 is provided inside the bottom of the positioning rod 62, and a support plate 64 is fixedly installed on the inner side of the sliding groove 63. Spring telescopic rods 65 are fixedly installed on both sides of the support plate 64. One end of the two spring telescopic rods 65 is fixedly installed with a clamping block 66. The two clamping blocks 66 are both slidably connected to the inner side of the sliding groove 63, and the two clamping blocks 66 are both arranged at the bottom of the top plate 24.

[0057] When disassembly is required and installation is required, the user can directly place the bottom of the clamping block 66 against the top of the top plate 24 and then press it downward. At this time, the clamping block 66 will move toward the inner side of the slide groove 63 until the clamping block 66 moves to the bottom of the top plate 24. Only then will the clamping block 66 move out from the inner side of the slide groove 63, thereby limiting the positioning rod 62.

[0058] The working principle of the adjustment device of the heavy-load leveling mechanism of a rail engineering vehicle provided by the utility model is as follows:

[0059] When in use, the top of the rubber pad 61 can be abutted against the top of the leveling base frame to play an anti-slip role. After long-term use, when the rubber pad 61 is severely worn, the user can push the two clamping blocks 66 to move the two clamping blocks 66 toward the inner side of the slide groove 63, thereby contracting the spring telescopic rod 65, and then moving the mounting plate 6 upward to remove the positioning rod 62 from the inside of the top plate 24, thereby disassembling the mounting plate 6 and the rubber pad 61.

[0060] Compared with related technologies, the adjustment device of the heavy-load leveling mechanism of a rail engineering vehicle provided by the present invention has the following beneficial effects:

[0061] By arranging the mounting plate 6 and the rubber pad 61 , the top of the rubber pad 61 can be brought into contact with the bottom of the leveling chassis during use, thereby playing an anti-slip role and increasing the stability of the support.

[0062] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
