[0002] With the development of globalization and technology, the innovation of ship equipment manufacturing technology gradually becomes the key discussion direction. Among them, when the heavy mechanism needs to be used at different positions on the ship, the walking mechanism on the ship drives the heavy mechanism to move along the track to the appropriate position. In order to realize the movement of the heavy mechanism, one end of the walking mechanism should be fixed on the track, and the other end can be connected with the heavy mechanism in an extendible manner. However, in order to fix one end of the walking mechanism on the track, the existing technology usually adopts the mechanical shaft hole cooperation mode, which needs to open a hole on the track. In this way, not only the manufacturing cost is increased, but also the overall work efficiency is reduced, and at the same time, the moving size of the heavy mechanism is also limited by the hole position. SUMMARY

[0004] To achieve the above purpose, the utility model is realized by the following technical scheme:
[0005] A walking mechanism, comprising a track for installation on a ship body, at least one transverse hydraulic cylinder arranged in parallel and spaced apart on the side surface of the track, one end of the transverse hydraulic cylinder being used for fixed connection with a heavy structure, and the telescopic rod at the other end of the transverse hydraulic cylinder being used for connection with a moving fixing assembly; the moving fixing assembly comprises a clamping plate and a vertical hydraulic cylinder having a piston rod inside, the vertical hydraulic cylinder being slidably connected to the upper surface of the track, the clamping plate being connected to the bottom end of the vertical hydraulic cylinder and being symmetrically distributed on the two side surfaces of the track, and the lower end of the piston rod being in mechanical connection with the clamping plate, so that the piston rod can drive the clamping plate to move upward to be clamped on the side surface of the track when moving downward.
[0006] Further, the upper end of the two side surfaces of the track is provided with a clamping groove, and the inner lower end of the clamping plate is provided with a buckle for fixed clamping with the clamping groove.
[0007] Further, the moving fixing assembly comprises a pressing block fixedly connected to the lower end of the piston rod inside the vertical hydraulic cylinder, and the pressing block is slidably connected to the upper surface of the track.
[0008] Further, the mobile fixing assembly further comprises a connecting plate, which is connected between the vertical hydraulic cylinder and the clamping plate by bolts and is located above the track, and a through hole for a pressing block is arranged in the middle position of the connecting plate; the connecting plate is configured to abut against the piston on the outer wall of the piston rod when the piston rod inside the vertical hydraulic cylinder moves downward.
[0009] Further, recesses for placing gaskets are arranged on the opposite sides of the bottom end of the connecting plate, and the gaskets are connected between the connecting plate and the clamping plate.
[0010] Further, the gaskets are hard gaskets with elastic properties.
[0011] Further, the depth of the recess is less than the thickness of the gasket, the clamping plate is configured to be clamped and fixed on the side surface of the track without contacting the connecting plate, and the gasket is in a completely compressed state.
[0012] Further, the opposite ends of the horizontal hydraulic cylinder are respectively provided with a first connecting head and a second connecting head, the first connecting head is used for fixed connection with the heavy structure, and the second connecting head is connected between the outer end of the telescopic rod of the horizontal hydraulic cylinder and the side end of the connecting plate.

The mechanical shaft hole cooperation method used when one end of the walking mechanism is fixed on the track is improved, the hole needs to be opened on the track, which not only increases the manufacturing cost but also reduces the overall working efficiency, and the movement size of the heavy mechanism is also limited by the hole position.

[0023] Please refer to the drawings Figure 1 to the drawings Figure 4The utility model discloses a first embodiment provides a kind of walking mechanism, including the track 1 for being installed on ship body, at least one parallel and interval is arranged in the lateral hydraulic cylinder 2 of track 1 side, one end of the lateral hydraulic cylinder 2 is used to be fixedly connected with heavy structure, the telescopic rod of the other end of the lateral hydraulic cylinder 2 is used to be connected with mobile fixed assembly.The mobile fixed assembly includes clamping plate 3 and the vertical hydraulic cylinder 4 with piston rod 41 in inside, the vertical hydraulic cylinder 4 can be slidably connected on the upper surface of the track 1, clamping plate 3 is connected with the bottom end of vertical hydraulic cylinder 4 and symmetrically distributed in the two side surfaces of track 1, and piston rod 41 lower end forms mechanical connection with clamping plate 3, so that piston rod 41 is brought when moving down, will drive clamping plate 3 to move up, to make clamping plate 3 be clamped and fixed in the side surface of track 1, to make the mobile fixed assembly in the walking mechanism of the utility model be automatically fixed on track 1 without additionally opening the jack hole matched with shaft on track 1, so, it is realized that lateral hydraulic cylinder only drives heavy structure to move laterally when being telescopic, and millimeter level control to the position movement of heavy mechanism can also be carried out.Improvement is needed when the end of walking mechanism is fixed on track in prior art, and the way of mechanical shaft hole cooperation is used, and the way needs to be opened on track, not only increase manufacturing cost, but also reduce overall working efficiency, and the movement size of heavy mechanism can also be subjected to the technical problem of hole position definition.However, it should be understood by those skilled in the art that the quantity and stroke of the lateral hydraulic cylinder 2 in the embodiment can be selected according to actual demand, and the utility model does not make specific limitation to the quantity and stroke of the lateral hydraulic cylinder 2.
[0024] Please refer to the attached Figure 1 to the attached Figure 4 In one preferable embodiment, the upper end of the two side surfaces of the track 1 is provided with a clamping groove 11, and the inner lower end of the clamping plate 3 is provided with a buckle 31 for fixed clamping with the clamping groove 11, so that the mobile fixed assembly can be stably fixed on the track by friction only, and there is no need to open a hole on the track 1 to cause the problem of weak strength of the track 1.
[0025] Please refer to the attached Figure 1 to the attached Figure 4 In one preferable embodiment, the mobile fixed assembly includes a pressing block 5 fixedly connected to the lower end of the piston rod 41 inside the vertical hydraulic cylinder 4, and the pressing block 5 can be slidably connected to the upper surface of the track 1 to facilitate position adjustment of the mobile fixed assembly when needed.
[0026] Please refer to the attached Figure 2 and the attached Figure 3In a preferred embodiment, the moving fixing assembly further comprises a connecting plate 6, which is connected between the vertical hydraulic cylinder 4 and the clamping plate 3 above the track 1, and a through hole 61 is formed in the middle of the connecting plate 6 for the pressure block 5 to pass through. When the connecting plate 6 moves downward inside the vertical hydraulic cylinder 4, the connecting plate 6 indirectly abuts against the piston 411 on the outer wall of the piston rod 41 to limit the downward movement range of the piston rod 41, so as to prevent the piston rod 41 from moving downward too much to damage the track 1.
[0027] Please refer to the accompanying drawings Figure 2 to the accompanying drawings Figure 4 In a preferred embodiment, the connecting plate 6 is provided with a recess 62 on the opposite sides of the bottom end for placing a gasket 7, and the gasket 7 is connected between the connecting plate 6 and the clamping plate 3. Preferably, the gasket 7 is a hard gasket with elastic properties, so that when the clamping plate 3 moves upward to press the gasket 7, the elastic hard gasket has enough space for the clamping plate 3 to move upward, so that the clamping plate 3 can be clamped and fixed to the side of the track 1.
[0028] Further, the depth of the recess 62 is less than the thickness of the gasket 7, and when the clamping plate 3 is clamped and fixed to the side of the track 1, the clamping plate 3 is not in contact with the connecting plate 6, so as to prevent the connecting plate 6 from limiting the upward movement of the clamping plate 3; and at this time, the gasket 7 is in a completely compressed state, so as to have enough rebound force to drive the clamping plate 3 to move downward with the subsequent gasket 7.
[0029] Please refer to the accompanying drawings Figure 1 In a preferred embodiment, the opposite ends of the horizontal hydraulic cylinder 2 are respectively provided with a first connecting head 8 and a second connecting head 9, the first connecting head 8 is used for fixed connection with the heavy structure, and the second connecting head 9 is connected between the outer end of the telescopic rod of the horizontal hydraulic cylinder 2 and the side end of the connecting plate 6, so that the horizontal hydraulic cylinder 2 can be connected with the heavy structure and the moving fixing assembly respectively through the first connecting head 8 and the second connecting head 9.
[0030] The working principle of the walking mechanism of the utility model is as follows:
[0031] When the heavy structure needs to be moved horizontally, the moving fixing assembly should be fixed on the track 1: only the vertical hydraulic cylinder 4 is started to move the piston rod 41 downward, and the piston rod 41 moves downward to drive the pressure block 5 to move downward and make the track 1 slightly tilt downward; when the piston rod 41 moves downward to indirectly abut against the connecting plate 6 on the outer wall of the piston 411, if the clamping plate 3 moves upward to press the gasket 7 at this time, when the buckle 31 on the clamping plate 3 is clamped in the clamping groove 11 of the track 1, the moving fixing assembly is fixed on the track 1, and the horizontal hydraulic cylinder 2 is started to drive the heavy structure to move horizontally to the appropriate position.
[0032] When the transverse hydraulic cylinder 2 with different strokes is adopted, the position of the moving fixing assembly needs to be adjusted: only the vertical hydraulic cylinder 4 is started, the piston rod 41 of the vertical hydraulic cylinder 4 is moved upward, at this time, the clamping plate 3 is moved downward to be away from (loosen the clamping) the track 1 under the rebound force of the gasket 7, then the transverse hydraulic cylinder 2 is started to drive the moving fixing assembly to move transversely on the track 1 to the appropriate position, and finally the piston rod 41 of the vertical hydraulic cylinder 4 is moved downward to fix the moving fixing assembly. The position of the moving fixing assembly of the utility model needs to be adjusted only by starting the vertical hydraulic cylinder 4 and the transverse hydraulic cylinder 2 in turn, which is not only convenient and efficient, but also can move the moving fixing assembly to any position on the track 1. However, when the position of the moving fixing assembly is adjusted by the traditional method, a plurality of holes need to be opened on the track 1, and the position adjustment of the moving fixing assembly is realized by the cooperation of different holes and shafts. Thus, not only the manufacturing cost is increased by opening a plurality of holes on the track 1, but also the strength of the track 1 is weakened, and the selection of the position adjustment of the moving fixing assembly is also less.
[0033] The above describes the embodiments only to illustrate the technical solutions of the utility model, rather than limit them. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced equivalently. These modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model. Therefore, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.
