Description

Technical Field

[0001] This application relates to the field of building construction, and more particularly, to a sliding-rolling friction conversion device and a method for horizontally pushing a building. Background Art

[0002] During the construction process, horizontal pushing and sliding conditions are common construction scenarios, especially in operations such as the transfer of materials and equipment, the overall pushing of buildings and structures, structural underpinning, displacement, and the laying of sliding tracks. Such conditions usually involve relative displacement between two interfaces or buildings, and the realization of the displacement depends on the frictional resistance between the interfaces and the externally applied force applied synchronously. To ensure the coherence of the pushing action, tools such as jacking equipment, jacks, jacking iron pads, and sliding plates are often used in construction, and lubricating materials are added to the object contact interface or the contact surface medium is changed to adjust the friction force and reduce the pushing resistance, thereby simplifying the construction difficulty.

[0003] However, due to the differences in the contact interface materials under different working conditions, the friction coefficients are often inconsistent, resulting in greater difficulty in horizontal pushing. Usually, external lubrication measures are required to reduce the friction. However, changing the interface friction is irreversible in some cases, especially in working conditions where the friction coefficient between buildings and structures needs to be adjusted intermittently to ensure safety during the horizontal pushing process.

[0004] In addition, temporary support systems or force transfer system structures are often involved in building construction. For example, the framework of the structural formwork support system is used to transfer the top concrete load, or the temporary loading platform at the construction site. These tools or support systems usually need to be repeatedly installed and disassembled at different locations, with complex procedures and long time consumption, increasing the complexity and time cost of construction. Summary of the Invention

[0005] The purpose of this application is to provide a sliding-rolling friction conversion device and a method for horizontally pushing a building, which can achieve the dual functions of horizontal pushing and fixing, simplify the disassembly and assembly steps, and save construction costs.

[0006] In a first aspect, the present invention provides a sliding-rolling friction conversion device, which includes a frame and a conversion assembly;

[0007] The frame is provided with two mounting positions, and the two mounting positions are arranged at both ends of the frame;

[0008] The number of the conversion components is two groups. One group of the conversion components is respectively located at one end of the frame. Each group of the conversion components includes a rolling ball, a first connecting piece and a lifting piece. One of the rolling balls is installed at a corresponding one of the installation positions. The lifting piece is installed at the end of the frame, and the lifting piece moves relative to the frame in a first direction. The first connecting piece is fixedly connected to the lifting end of the lifting piece. Driven by the lifting piece, the first connecting piece moves relative to the frame in the first direction between a first position and a second position. The first position is closer to the frame than the second position. Along the first direction, the outermost point of the rolling ball is located between the first position and the second position.

[0009] In an alternative embodiment, the two installation positions are configured to be hemispherical, and the two installation positions are symmetrically arranged along a second direction perpendicular to the first direction.

[0010] In an alternative embodiment, the rolling-sliding friction conversion device further includes a control cabinet and a power generation motor. The control cabinet and the power generation motor are installed on the frame, and the control cabinet and the power generation motor are located between the two installation positions. The power generation motor is electrically connected to the control cabinet and the lifting piece.

[0011] In an alternative embodiment, the first connecting piece includes a connecting body and a ribbed alloy steel plate. The connecting body is fixed to the lifting end, and the ribbed alloy steel plate is arranged at one end of the connecting body away from the frame.

[0012] In an alternative embodiment, within each group of the conversion components, the number of the first connecting pieces is at least two, and the two first connecting pieces extend along a third direction perpendicular to the first direction.

[0013] In an alternative embodiment, each group of the conversion components further includes a second connecting piece, and the second connecting piece is supported between the frame and the lifting piece.

[0014] In an alternative embodiment, within each group of the conversion components, the number of the second connecting pieces is at least two, and the two second connecting pieces extend along a third direction perpendicular to the first direction.

[0015] In an alternative embodiment, the frame includes connecting side plates and steel pier columns. A receiving space is defined between at least two of the connecting side plates. The steel pier columns are arranged in the receiving space, and the installation positions are provided on the steel pier columns. The lifting piece is installed on the connecting side plates.

[0016] In an alternative embodiment, the rolling ball is configured to be an alloy wear-resistant ball, and the friction coefficient of the alloy wear-resistant ball is less than the friction coefficient of the first connecting piece.

[0017] In a second aspect, the present invention provides a method for horizontally pushing a building, using the rolling-sliding friction conversion device described in the foregoing embodiments. The method for horizontally pushing a building includes: placing the rolling-sliding friction conversion device between a first building and a second building, adjusting the conversion assembly close to the first building so that the first connecting member of this group moves to a second position, adjusting the conversion assembly close to the second building so that the first connecting member of this group moves to a first position, pushing the second building to translate on the rolling balls. After the horizontal pushing is in place, adjust the conversion assembly close to the second building again so that the first connecting member of this group moves to the second position to fix the second building.

[0018] Compared with the prior art, the beneficial effects of the present application are as follows:

[0019] In the present application, the lifting member drives the first connecting member to move up and down between a first position and a second position. When the first connecting member is adjusted to the first position, at this time, the outermost point of the rolling ball protrudes outside the first position, and the building on the rolling ball is pushed to achieve horizontal pushing. When the first connecting member is adjusted to the second position, at this time, the outermost point of the rolling ball is concave inside the second position to fix the building. The present application can achieve the dual functions of horizontal pushing and fixing, with simple and convenient switching, simplified disassembly and assembly steps, and cost savings in construction.

[0033] Embodiment 1

[0034] Please refer to Figure 1 and Figure 2 , this embodiment is applicable to the pushing and fixing between two buildings. For the convenience of narration and understanding, in this embodiment, the building located below is defined as the first building 20, and the building located above is defined as the second building 30. Here, the pushing refers to the relative horizontal movement of the second building 30 relative to the first building 20, and the fixing refers to the non-occurrence of relative movement between the second building 30 and the first building 20.

[0035] Due to the large masses of the first building 20 and the second building 30, relatively high requirements are imposed on the stiffness of this embodiment.

[0036] This embodiment provides a sliding-rolling friction conversion device 10. The sliding-rolling friction conversion device 10 is placed between the first building 20 and the second building 30. The sliding-rolling friction conversion device 10 includes a frame 100 and a conversion assembly 200.

[0037] The frame 100 is provided with two mounting positions, and the two mounting positions are arranged at both ends of the frame 100; in this embodiment, it can be set that the frame 100 includes connecting side plates 110 and steel pier columns 120. An accommodation space is defined between at least two connecting side plates 110, and the steel pier columns 120 are arranged in the accommodation space, and mounting positions are provided at both ends of the steel pier columns 120.

[0038] For the convenience of installing the conversion assembly 200 in the following text, the connecting side plates 110 need to have a certain thickness so as to reserve mounting positions.

[0039] During actual assembly, the connecting side plates 110 are welded to the steel pier columns 120. The steel pier columns 120 are made of stainless steel and have relatively high hardness and stiffness, which can ensure that the sliding-rolling friction conversion device 10 will not be damaged due to excessive pressure between the first building 20 and the second building 30.

[0040] In some embodiments, the two mounting positions are configured to be hemispherical, and the two mounting positions are symmetrically arranged along a second direction perpendicular to the first direction.

[0041] There are two groups of conversion assemblies 200 . One group of conversion assemblies 200 is located at one end of the frame 100 . Each group of conversion assemblies 200 includes a rolling ball 210 , a first connecting member 220 and a lifting member 230 .

[0042] A rolling ball 210 is installed in a corresponding installation position, and the rolling ball 210 is configured as an alloy wear-resistant ball, and the friction coefficient of the alloy wear-resistant ball is smaller than the friction coefficient of the first connecting member 220. It can be understood that the hemispherical shape is conducive to the rolling of the rolling ball 210 in the installation position and can prevent the rolling ball 210 from leaving the installation position.

[0043] In this embodiment, the point of the rolling ball 210 farthest from the installation position is defined as the outermost point. When the outermost point contacts the building, the outermost point is the contact point between the rolling ball 210 and the building. By changing the contact point, horizontal pushing is achieved.

[0044] The lifting member 230 is installed at the end of the frame 100, and the lifting member 230 moves in the first direction relative to the frame 100. The lifting member 230 is installed on the end of the connecting side plate 110. This embodiment can appropriately adjust the telescopic length of the lifting member 230 according to the distance between the first building 20 and the second building 30, expand the scope of application, and has good adaptability.

[0045] The lifting member 230 may be configured as an element with a telescopic function, such as a cylinder, a hydraulic cylinder or a jack.

[0046] The first connecting member 220 is fixedly connected to the lifting end of the lifting member 230 .

[0047] See also Figure 2 and Figure 3 The first connecting member 220 includes a connecting body 221 and a ribbed alloy steel plate 222 . The connecting body 221 is fixed to the lifting end, and the ribbed alloy steel plate 222 is arranged at an end of the connecting body 221 away from the frame 100 .

[0048] See also Figure 1 , Figure 2 and Figure 4 In each group of conversion components 200 , the number of the first connecting members 220 is at least two, the two first connecting members 220 extend along a third direction perpendicular to the first direction, and each first connecting member 220 is fixedly connected to at least one lifting member 230 .

[0049] Each set of conversion components 200 further includes a second connection member 240, which is supported between the frame 100 and the lifting member 230. The second connection member 240 serves as a supporting element of the lifting member 230, dispersing the pressure of the second building 30 on the present embodiment, thereby improving the stability and reliability of the present embodiment.

[0050] Within each set of conversion components 200, the number of the second connecting members 240 is at least two, and the two second connecting members 240 extend along a third direction perpendicular to the first direction.

[0051] In this embodiment, two first connecting members 220, two second connecting members 240 and two lifting members 230 are taken as a set of conversion components 200 for exemplary illustration.

[0052] In some other embodiments, the numbers of the first connecting member 220, the second connecting member 240 and the lifting member 230 are not limited. For example, please further refer to Figure 4 , three lifting members 230 are arranged under one first connecting member 220, and the three lifting members 230 are arranged at intervals along the extending direction of the first connecting member 220 (i.e., the third direction).

[0053] Please continue to refer to Figure 1 , driven by the lifting member 230, the first connecting member 220 moves relative to the frame 100 along the first direction between a first position and a second position. The first position is closer to the frame 100 than the second position. Along the first direction, the outermost point of the rolling ball 210 is located between the first position and the second position.

[0054] Therefore, when fixing the second building 30 and the first building 20, the lifting member 230 can not only adjust the position of the first connecting member 220 so that the first connecting member 220 protrudes out of the outermost point of the rolling ball 210, but also can reasonably adjust the overall height of the sliding-rolling friction conversion device 10 according to the distance between the first building 20 and the second building 30, thereby expanding the applicable range.

[0055] Please refer to Figure 5 , when pushing the building horizontally, according to the construction requirements, select the first connecting member 220 in one set of conversion components 200 to protrude out of the outermost point of the rolling ball 210, fix the building corresponding to this set of conversion components 200, and make the first connecting member 220 in the other set of conversion components 200 concave into the outermost point of the rolling ball 210, and push the building corresponding to this set of conversion components 200 horizontally.

[0056] The above-mentioned protrusion means that the outer contour of the first connecting member 220 is outside the outer contour of the rolling ball 210, and the concavity means that the outer contour of the first connecting member 220 is inside the outer contour of the rolling ball 210.

[0057] Since it is set in this embodiment to move the second building 30, therefore, in the conversion components 200 located below, the first connecting member 220 is lower than the outermost point of the rolling ball 210, so as to fix the first building 20, and in the conversion components 200 located above, the first connecting member 220 is lower than the outermost point of the rolling ball 210, so as to push the second building 30 horizontally.

[0058] This embodiment can achieve the change of friction resistance between different buildings. Given that the rolling friction coefficient is much smaller than the sliding friction, the controllability of the horizontal pushing and translation process can be achieved through this embodiment and adjusted as needed.

[0059] It can be understood that this embodiment is also applicable to the upper and lower ends of the standardized support system. Adjust the first connectors 220 of the two sets of conversion components 200 to protrude outward from the outermost point of the rolling balls 210, so that the ribbed alloy steel plates 222 are in contact with the upper and lower surfaces of the standardized support system to achieve temporary fixation. When the standardized support system needs to be removed, adjust at least one set of the first connectors 220 to be concave inward from the outermost point of the rolling balls 210, so that the rolling balls 210 are in contact with the flat surface of the standardized support system, realizing the overall horizontal pushing of the standardized support system, quickly supporting in place, quickly removing and evacuating, saving the construction period, improving work efficiency, saving costs, and creating economic benefits.

[0060] This embodiment can be pre-embedded with the upper and lower buildings or the standardized support system in advance, perform force transfer and friction resistance conversion adjustment during the process, and realize the on-demand controllability of the horizontal pushing process.

[0061] Please refer to Figure 1 and Figure 5 , based on the above content, the building horizontal pushing method of this embodiment is further described as follows:

[0062] S100. Place the sliding-rolling friction conversion device 10 between the first building 20 and the second building 30.

[0063] S200. Adjust the conversion component 200 close to the first building 20 so that the first connector 220 of this group moves to the second position.

[0064] In the conversion component 200 located below, the first connector 220 protrudes outward from the rolling ball 210 to fix the first building 20.

[0065] S300. Adjust the conversion component 200 close to the second building 30 so that the first connector 220 of this group moves to the first position, and push the second building 30 to translate on the rolling balls 210.

[0066] In the conversion component 200 located above, the first connector 220 is concave inward from the rolling ball 210 to achieve the horizontal pushing of the second building 30.

[0067] S400. After the horizontal pushing is in place, adjust the conversion component 200 close to the second building 30 again so that the first connector 220 of this group moves to the second position to fix the second building 30.

[0068] In the conversion component 200 located above, the first connecting piece 220 protrudes outward from the rolling ball 210 to fix the second building 30.

[0069] In this embodiment, the lifting member 230 drives the first connecting piece 220 to move up and down between a first position and a second position. When the first connecting piece 220 is adjusted to the first position, the outermost point of the rolling ball 210 protrudes outward from the first position, pushing the building on the rolling ball 210 for a flat push. When the first connecting piece 220 is adjusted to the second position, the outermost point of the rolling ball 210 is concave inward from the second position to fix the building. This embodiment can achieve the dual functions of flat push and fixation, with simple and convenient switching, simplified disassembly and assembly steps, and cost savings in construction.

[0070] Embodiment Two

[0071] Please refer to Figure 1 and Figure 2 Based on Embodiment One, this embodiment is improved. The improvement lies in that the sliding-rolling friction conversion device 10 further includes a control cabinet 300 and a power generation motor 400. The control cabinet 300 and the power generation motor 400 are installed on the frame 100, and the control cabinet 300 and the power generation motor 400 are located between two installation positions. The power generation motor 400 is electrically connected to the control cabinet 300 and the lifting member 230.

[0072] One side of the power generation motor 400 is provided with a heat dissipation hole, and the other side is provided with a switch. The current selectively supplies power to the control cabinet 300 and the lifting member 230 through the opening and closing of the switch. The control cabinet 300 is electrically connected to the lifting member 230, realizing automatic conversion.

[0073] This embodiment realizes self-power supply of the sliding-rolling friction conversion device 10 through the power generation motor 400, without the need for an additional power source, which conforms to the working conditions of on-site construction. Moreover, this application uses the control cabinet 300 to realize automatic control of the lifting member 230, simplifies the switching method, and reduces the usage difficulty.
