Description

Technical Field

[0001] This utility model relates to the field of underwater leveling machine technology, and in particular to a vertical lifting support device for an underwater leveling machine. Background Technology

[0002] An underwater screed is a type of machinery specifically designed for underwater earthwork leveling operations. It is widely used in marine engineering, water conservancy projects, and other fields. Through its unique design and structure, the underwater screed can effectively level soil underwater to achieve the desired smoothness.

[0003] like Figure 5 As shown, the walking underwater screed moves by walking legs 10. Currently, because the walking legs 10 are underwater during operation, they are constantly affected by currents and waves and cannot be observed. When the bottom of the walking legs 10 comes into contact with some hard rocks 11, a small area of ​​the bottom of the walking legs 10 can easily come into contact with the rocks 11, causing the walking legs 10 to bend and deform, which affects the construction safety of the underwater screed.

[0004] To address the aforementioned problems, patent (publication number: CN220132916U) discloses a support leg for an underwater screed, comprising: a support leg base, a support block, a first ball groove, a first connecting ball, a hydraulic telescopic assembly, and an elastic element; multiple plunger components, vertically arranged between the support block and the support leg base, evenly distributed along the edge of the support block, with the upper end of each plunger component fixedly connected to the support block and the lower end of each plunger component movably connected to the support leg base; a flow guiding assembly, disposed inside the support block and communicating with the multiple plunger components to balance the internal pressure of the multiple plunger components; and multiple reset assemblies, respectively disposed on the multiple plunger components, to reset each plunger component after telescoping. This invention enables the support leg base to adjust its swing direction according to the leveling state of the base bed, preventing the support leg base from breaking or being damaged when the screed moves on the base bed, ensuring the normal operation of the screed and improving the working efficiency of the screed.

[0005] However, in actual work, it was found that the above structure has certain defects. Because the bottom of the construction dock is often a mixture of stones and silt of different outer diameters, the plunger and the first connecting ball are often filled with small stones and silt, which makes the support foot seat unable to rotate. This sometimes makes it impossible to solve the problem of the support foot seat breaking or being damaged when the leveling machine moves on the base bed. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, which is that the bottom of the construction dock is often a mixture of stones and silt of different outer diameters, which often causes the plunger and the first connecting ball to be filled with small stones and silt, making it impossible for the support foot to rotate. This makes it sometimes unable to solve the problem of the support foot breaking or being damaged when the leveling machine moves on the base bed. The present invention provides a vertical lifting support device for underwater leveling machines.

[0007] In a first aspect, the present invention provides a vertical lifting support device for an underwater leveling machine, comprising a telescopic mechanism and a support structure, wherein the support structure is connected to the bottom of the telescopic mechanism; the bottom of the support structure is provided with a downwardly protruding spherical surface, and a plurality of conical protrusions are provided on the spherical surface, the conical protrusions being arranged along the normal direction of the spherical surface, and the height of the conical protrusion located in the middle of the spherical surface being higher than that of the conical protrusions on the side of the spherical surface.

[0008] The vertical lifting support device for an underwater screed machine described in this application has a downwardly protruding spherical surface at the bottom of the support structure, and several conical protrusions on the spherical surface. During the downward pressing process of the support structure, when encountering a stone with a large outer diameter, if part of the support structure presses down on the stone, the characteristics of the spherical surface itself, coupled with the fact that the conical protrusions are arranged along the normal direction of the spherical surface and the height of the conical protrusions located in the middle of the spherical surface is higher than that of the conical protrusions on the side of the spherical surface, will squeeze the stone to one side, causing the stone to move to one side. This effectively reduces the probability of only a small part of the bottom of the vertical lifting support device for the underwater screed machine contacting the stone, thus ensuring the construction safety of the underwater screed machine.

[0009] Preferably, the conical protrusions are arranged in a row, and the height of all the conical protrusions decreases sequentially from the middle of the spherical surface to the edge of the spherical surface.

[0010] Preferably, the support structure includes a vertical beam detachably connected to the telescopic mechanism, a first expanded panel is connected to the bottom of the vertical beam, the first expanded panel protrudes from the vertical beam around its perimeter; a second expanded panel is connected to the bottom of the first expanded panel, the second expanded panel protrudes from the second expanded panel around its perimeter, and an outwardly convex structure is connected to the bottom of the second expanded panel, the spherical surface being the bottom surface of the outwardly convex structure.

[0011] By progressively expanding the bottom area of ​​the support structure through the first and second expansion panels, the problem of excessive sinking of the vertical lifting support device for underwater leveling machines caused by the setting of spherical and conical protrusions is effectively solved.

[0012] Preferably, a stiffening plate connects the second expansion panel to the vertical beam.

[0013] Preferably, the telescopic mechanism and the support structure are detachably connected by a bolt group.

[0014] Preferably, the bolt group includes multiple bolts connected circumferentially around the vertical beam, and a washer is fitted on the bolt located on at least one side of the vertical beam, the washer being located between the telescopic mechanism and the support structure.

[0015] Preferably, the vertical lifting support device for an underwater leveling machine described in this application further includes a support beam and a vertical support gantry, wherein:

[0016] The telescopic mechanism includes a fixed rod and a movable rod that slide against each other;

[0017] The support beam is provided with a vertical through hole, and the movable rod is vertically slidingly engaged with the vertical through hole;

[0018] The vertical support gantry is connected to the upper part of the support beam, and the vertical support gantry is connected to the upper part of the fixed rod.

[0019] The underwater leveling machine described in this application has a vertical support gantry connected to the upper part of the support beam, serving as the support structure for the telescopic mechanism. The support beam is provided with a vertical through hole, and the vertical sliding cooperation between the vertical through hole and the movable rod achieves the purpose of raising and lowering the support structure.

[0020] Furthermore, by setting up a vertical support gantry, the height of the support beam is effectively reduced, thereby increasing the overall stability of the underwater leveling machine of this application.

[0021] Furthermore, by providing a downwardly protruding spherical surface at the bottom of the support structure, and setting several conical protrusions on the spherical surface, when the support structure encounters a stone with a large outer diameter during the downward pressing process, if part of the support structure presses down on the stone, the characteristics of the spherical surface itself, coupled with the fact that the conical protrusions are set along the normal direction of the spherical surface and the height of the conical protrusions located in the middle of the spherical surface is higher than that of the conical protrusions on the side of the spherical surface, will squeeze the stone to one side, causing the stone to move to one side. This effectively reduces the probability of only a small part of the bottom of the vertical lifting support device for the underwater leveling machine contacting the stone, thus ensuring the construction safety of the underwater leveling machine.

[0022] Preferably, the support beam and the vertical support gantry are detachably connected to facilitate installation and replacement.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] The vertical lifting support device for an underwater screed machine described in this application has a downwardly protruding spherical surface at the bottom of the support structure, and several conical protrusions on the spherical surface. During the downward pressing process of the support structure, when encountering a stone with a large outer diameter, if part of the support structure presses down on the stone, the characteristics of the spherical surface itself, coupled with the fact that the conical protrusions are arranged along the normal direction of the spherical surface and the height of the conical protrusions located in the middle of the spherical surface is higher than that of the conical protrusions on the side of the spherical surface, will squeeze the stone to one side, causing the stone to move to one side. This effectively reduces the probability of only a small part of the bottom of the vertical lifting support device for the underwater screed machine contacting the stone, thus ensuring the construction safety of the underwater screed machine.

[0038] The vertical lifting support device for an underwater leveling machine described in this application has a downwardly protruding spherical surface 31 at the bottom of the support structure 2, and several conical protrusions 32 on the spherical surface 31. During the downward pressing of the support structure 2, when encountering a stone with a large outer diameter, if part of the support structure 2 presses down on the stone, the characteristics of the spherical surface 31 itself, plus the fact that the conical protrusions 32 are arranged along the normal direction of the spherical surface 31, and the height of the conical protrusions 32 located in the middle of the spherical surface 31 is higher than that of the conical protrusions 32 on the side of the spherical surface 31, will squeeze the stone to one side, causing the stone to move to one side. This effectively reduces the probability that only a small part of the bottom of the vertical lifting support device for an underwater leveling machine will contact the stone, thus ensuring the construction safety of the underwater leveling machine.

[0039] In one preferred embodiment, the conical protrusions 32 are arranged in a row, and the height of all the conical protrusions 32 decreases sequentially from the middle of the spherical surface 31 to the edge of the spherical surface 31. For example... Figure 1 As shown, D1 > D2.

The bottom of the second expansion panel 23 is connected to an outwardly convex structure 24, and the spherical surface 31 is the bottom surface of the outwardly convex structure 24.

[0041] By progressively expanding the bottom area of ​​the support structure 2 through the first expansion panel 22 and the second expansion panel 23, the problem of excessive sinking of the vertical lifting support device for an underwater leveling machine caused by the setting of the spherical surface 31 and the conical protrusion 32 is effectively solved.

[0042] The conical boss 32 is preferably a frustum or a cone, and the small end of the frustum can be a hemispherical structure.

[0050] The underwater leveling machine described in this application has a vertical support gantry 5 connected to the upper part of the support beam 4, serving as the support structure for the telescopic mechanism 1. The support beam 4 is provided with a vertical through hole 41, and the vertical sliding cooperation between the vertical through hole 41 and the movable rod 12 is used to achieve the purpose of raising and lowering the support structure 2.

[0051] Furthermore, by setting up a vertical support gantry 5, the height of the support beam 4 is effectively reduced, thereby increasing the overall stability of the underwater leveling machine of this application.

[0052] Furthermore, by providing a downwardly protruding spherical surface 31 at the bottom of the support structure 2, and by providing several conical protrusions 32 on the spherical surface 31, when the support structure 2 encounters a stone with a large outer diameter during the downward pressing process, if part of the support structure 2 presses down on the stone, the characteristics of the spherical surface 31 itself, coupled with the fact that the conical protrusions 32 are arranged along the normal direction of the spherical surface 31, and the height of the conical protrusions 32 located in the middle of the spherical surface 31 is higher than that of the conical protrusions 32 on the side of the spherical surface 31, will squeeze the stone to one side, causing the stone to move to one side.
