Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a building pushing device. Background Art

[0002] In recent years, the technology for relocating entire buildings has rapidly developed. Based on the surrounding conditions and planning requirements, relocation can be implemented within a certain range to preserve the building and achieve desired results, with significant economic benefits. Specifically, this technology uses a support mechanism to separate the building from its foundation, then install a traveling mechanism to allow the building to move horizontally. Finally, a hydraulic actuator pushes the building horizontally at one end, while the other end is horizontally restrained to a reaction support, allowing the building to shift horizontally on the traveling mechanism.

[0003] In related technologies, building jacking equipment includes reaction supports. To temporarily place the reaction supports on the track beams, manual work is required to lay pads on the track beams to provide temporary support and position for the reaction supports. This additional manual operation step is detrimental to improving construction efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a building pushing device, which aims to reduce manual operation steps and improve construction efficiency.

[0006] In one embodiment, the supporting portion is recessed with a stop groove along the vertical direction, and the end portion of the limiting member is inserted into the stop groove.

[0007] In one embodiment, the supporting portion and the stop assembly are integrally formed.

One stop assembly and the track beam are combined to form a limit groove, and a supporting portion is protruded from one side of the groove wall of the limit groove. One side of the reaction force bracket is protruded from multiple limit members arranged at intervals in the horizontal direction, and one limit member abuts against one supporting portion.

[0009] In one embodiment, the plurality of supporting portions and the plurality of limiting members are respectively arranged at intervals along the same horizontal line.

[0010] In one embodiment, a supporting portion is protruded from both sides of the groove wall of the limiting groove along the horizontal direction, wherein one of the supporting portions abuts against the limiting member.

[0011] In one embodiment, the stop assembly includes two stop members, which are arranged on the track beam at intervals along the horizontal direction, and the two stop members and the track beam are enclosed to form the limiting groove.

[0012] In one embodiment, a first reinforcing rib is protruded from a side of the stopper away from the supporting portion, and a bottom end of the first reinforcing rib is also connected to the track beam.

[0013] In one embodiment, a second reinforcing rib is protruded from one side of the limiting member along the horizontal direction, and the bottom end of the second reinforcing rib is also connected to the reaction support.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0028] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), such directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] In recent years, the technology for relocating entire buildings has rapidly developed. Based on the surrounding conditions and planning requirements, relocation can be implemented within a certain range to preserve the building and achieve desired results, with significant economic benefits. Specifically, this technology uses a support mechanism to separate the building from its foundation, then install a traveling mechanism to allow the building to move horizontally. Finally, a hydraulic actuator pushes the building horizontally at one end, while the other end is horizontally restrained to a reaction support, allowing the building to shift horizontally on the traveling mechanism.

[0031] In related art, building jacking equipment includes a track beam, a stop assembly, and a reaction bracket. The stop assembly is located on one side of the track beam and forms a limit slot with the track beam. The reaction bracket is horizontally restrained by the groove wall. Therefore, when the hydraulic drive is used to horizontally push the building, the reaction bracket can horizontally restrain the hydraulic drive when the limit slot is horizontally restrained.

[0032] However, in order to temporarily place the reaction support in the limiting groove, it is necessary to manually lay pads in the limiting groove to temporarily support the reaction support through the pads. Since the manual operation steps are required, it is not conducive to improving construction efficiency.

[0033] In order to solve the above problems, the present invention proposes a building pushing device 100, which aims to reduce manual operation steps and improve construction efficiency.

[0034] Reference Figures 1 to 7 In one embodiment of the present utility model, the building pushing equipment 100 includes a track beam 1, a stop assembly 2 and a reaction support 3, the track beam 1 is installed on the ground; the stop assembly 2 is arranged on the side of the track beam 1 away from the ground, and is enclosed with the track beam 1 to form a limiting groove 25, and the side wall of the limiting groove 25 is provided with a supporting portion 251; a limiting member 35 is provided on one side of the reaction support 3, the limiting member 35 abuts against the supporting portion 251 in the vertical direction, and is limited to the groove wall of the limiting groove 25 in the horizontal direction.

[0035] The track beam 1 is a crucial component of the traveling mechanism. It is typically connected to pre-installed fasteners for ground installation, providing support and guidance for the entire building jacking device 100. The reaction support 3 serves as the rear anchor beam for the hydraulic drive 40. When squeezed by the hydraulic drive 40, the reaction support 3 applies a counter-thrusting force to the hydraulic drive 40, thereby limiting its horizontal position.

[0036] A supporting beam 91 is provided at the bottom of the building 93. The supporting beam 91 serves as a stable platform during the movement of the building 93, thereby reducing vibration and shaking of the building 93 during the movement and improving the stability of the movement process.

[0037] In the technical solution of the present utility model, the stopper assembly 2 is disposed on the side of the track beam 1 facing away from the ground, and together with the track beam 1, forms a limit groove 25 with an open top. The reaction support 3 is horizontally restrained by the groove wall of the limit groove 25. Therefore, when the hydraulic drive 40 is used to horizontally push the building 93, the reaction support 3 can horizontally limit the hydraulic drive 40 and apply a corresponding reverse thrust.

[0038] It is worth noting that when the reaction support 3 is temporarily placed in the limit groove 25, since the wall of the limit groove 25 is convexly provided with a supporting portion 251, the reaction support 3 can be directly temporarily supported by the supporting portion 251, thereby avoiding the need to manually lay pads in the limit groove 25, reducing the steps of manual operation, and thus helping to improve construction efficiency.

[0039] Reference Figure 5In one embodiment of the present invention, the supporting portion 251 is provided with a stop groove in the vertical direction, and the end of the limiting member 35 is inserted into the stop groove.

[0040] In this embodiment, the design of the stop groove ensures precise vertical positioning of the limiter 35, reducing instability caused by the deviation of the limiter 35. The close fit between the limiter 35 and the stop groove effectively limits the vertical movement of the limiter 35, thereby improving the stability of the entire system.

[0041] Reference Figure 5 In one embodiment of the present invention, the supporting portion 251 and the stop assembly 2 are integrally formed.

[0042] In this embodiment, the integrated molding can improve the structural strength between the supporting portion 251 and the stopper assembly 2, reducing deformation or loosening that may occur during long-term use. The integrated design reduces the workload of on-site assembly and improves installation efficiency.

[0043] Reference Figure 1 and Figure 2 In one embodiment of the present utility model, there are multiple stop assemblies 2, and the multiple stop assemblies 2 are arranged at intervals in the horizontal direction. One stop assembly 2 and the track beam 1 are enclosed to form a limiting groove 25, and a supporting portion 251 is protruded from one side of the groove wall of the limiting groove 25. One side of the reaction force bracket 3 is protruded with multiple limiting members 35 arranged at intervals in the horizontal direction, and one limiting member 35 abuts against one supporting portion 251.

[0044] In this embodiment, the design of multiple sets of limiters 35 and supporting parts 251 can better disperse the weight of the reaction support 3, ensure load balance, and further achieve stable placement of the reaction support 3, thereby helping to improve construction efficiency.

[0045] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the plurality of supporting portions 251 and the plurality of limiting members 35 are spaced apart along the same horizontal line.

[0046] In this embodiment, by arranging multiple supporting portions 251 and limiting members 35 at intervals along the same horizontal line, the reaction support 3 is supported by the supporting portions 251 along the same horizontal line, avoiding the undesirable overload caused by a single supporting portion 251 supporting a single limiting member 35. Furthermore, this allows for better adaptation to varying terrain and helps improve the stability of the entire system.

[0047] Reference Figure 5In one embodiment of the present invention, a supporting portion 251 is protruded from both sides of the groove wall of the limiting groove 25 along the horizontal direction, and one of the supporting portions 251 abuts against the limiting member 35.

[0048] In this embodiment, the design of the dual supporting portions 251 allows the reaction bracket 3 to be placed on both sides of the limiting groove 25, so that both sides of the reaction bracket 3 can be horizontally limited by the groove wall of the limiting groove 25. Therefore, when the hydraulic drive component 40 needs to be limited in the opposite direction, the reaction bracket 3 can be placed on the other supporting portion 251 to meet the opposite direction of the hydraulic drive component 40, thereby improving construction efficiency.

[0049] Reference Figure 5 In one embodiment of the present invention, the stop assembly 2 includes two stop members 21 , and the two stop members 21 are arranged on the track beam 1 at intervals along the horizontal direction. The two stop members 21 and the track beam 1 enclose the limiting groove 25 to form.

[0050] In this embodiment, the stopper assembly 2 comprises two stoppers 21, which are horizontally spaced apart on the track beam 1 and, together with the track beam 1, form a stopper groove 25. This structural design is simple and easy to implement, as well as to install and disassemble, making the entire device easy to manufacture and reducing production costs.

[0051] Reference Figure 5 In one embodiment of the present invention, a first reinforcing rib 211 is protruded from the side of the stopper 21 away from the supporting portion 251 , and the bottom end of the first reinforcing rib 211 is also connected to the track beam 1 .

[0052] In this embodiment, a first reinforcing rib 211 is provided on the side of the stopper 21 facing away from the supporting portion 251, and the bottom end of the first reinforcing rib 211 is connected to the track beam 1. Such a design can significantly improve the structural strength of the stopper 21 and reduce deformation when subjected to heavy pressure.

[0053] Reference Figure 5 In one embodiment of the present invention, a second reinforcing rib 351 is protruded from one side of the limiting member 35 along the horizontal direction, and the bottom end of the second reinforcing rib 351 is also connected to the reaction support 3.

[0054] In this embodiment, a second reinforcing rib 351 is provided on one side of the limit member 35 in the horizontal direction, and the bottom end of the second reinforcing rib 351 is connected to the reaction support 3. Such a design can improve the structural strength of the limit member 35 and reduce the deformation of the limit member 35 during the pushing process.

[0055] Reference Figures 1 to 4In one embodiment of the present utility model, the building pushing equipment 100 also includes an auxiliary roller assembly 50 and a support roller 60. The auxiliary roller assembly 50 is arranged on the side of the track beam 1 away from the ground. The auxiliary roller assembly 50 has at least one auxiliary shaft 513, and the auxiliary shaft 513 is rotatable around an extension direction perpendicular to the track beam 1; one side of the support roller 60 abuts against the auxiliary shaft 513 in the vertical direction, and the other side of the support roller 60 away from the auxiliary shaft 513 is used to support the building 93, so that the building 93 can be moved in the horizontal direction.

[0056] In this embodiment, the auxiliary roller assembly 50 is horizontally laid flat on the track beam 1 and is used to provide rolling support for the support roller 60 via the auxiliary shaft 513. The side of the support roller 60 facing away from the auxiliary shaft 513 is used to support the building 93. It is worth noting that during the process of the hydraulic drive 40 horizontally pushing the building 93, the support roller 60 rolls against the auxiliary shaft 513. Therefore, the support roller 60 is directly subjected to the rolling friction force of the auxiliary shaft 513, which reacts on the building 93. Because the rolling friction force is much smaller than the sliding friction force, the normal displacement speed of the building 93 can be maintained, which is conducive to improving construction efficiency.

[0057] Reference Figures 1 to 4 In one embodiment of the present invention, the roller member 51 includes two mounting seats 511 and an auxiliary shaft 513. The two mounting seats 511 are respectively connected to the track beam 1 and are spaced apart perpendicular to the extension direction of the track beam 1. The two ends of the auxiliary shaft 513 are respectively rotatably connected to the two mounting seats 511.

[0058] In this embodiment, the auxiliary shaft 513 is secured by two mounting brackets 511, ensuring the stability of the auxiliary shaft 513 and, in turn, the stable support of the support roller 60. The design of the mounting brackets 511 makes the auxiliary shaft 513 easy to install and replace, facilitating rapid on-site assembly and subsequent maintenance. The auxiliary shaft 513 is rotatably connected to the mounting brackets 511 at both ends, reducing friction between the mounting brackets 511 and the auxiliary shaft 513, thereby extending its service life.

[0059] Optionally, the auxiliary shaft 513 is provided with an axial hole along the axial direction, the shaft core 5131 is passed through the axial hole, and both ends are rotatably connected to the mounting seat 511 through bearings. The mounting seat 511 and the auxiliary shaft 513 are designed as a standardized module to facilitate mass production and rapid on-site assembly.

[0060] Reference Figure 5In one embodiment of the present invention, the building pushing equipment 100 includes a supporting member 70, which is connected to one side of the reaction support 3 in the horizontal direction; the hydraulic drive member 40 is supported on the supporting member 70 in the vertical direction.

[0061] The hydraulic drive member 40 includes a base 41 and a telescopic portion 43. The base 41 is placed on the supporting member 70. The telescopic portion 43 is driven by hydraulic pressure to extend and retract to achieve the jacking of the building 93. For example, the hydraulic drive member 40 is selected as a hydraulic jack.

[0062] In this embodiment, before the hydraulic drive component 40 is pushed, since the reaction support 3 is supported on the track beam 1, the supporting member 70 can be used to temporarily position and support the hydraulic drive component 40, avoiding the continuous occupation of the crane as a construction component, which is beneficial to reducing construction costs and improving construction efficiency.

[0063] Reference Figure 1 、 Figure 6 and Figure 7 In one embodiment of the present invention, the supporting member 70 is provided with a mounting groove 71 in a vertical direction, and the hole wall of the mounting groove 71 abuts against the hydraulic driving member 40 .

[0064] In this embodiment, the provision of mounting grooves 71 on the support member 70 ensures good vertical stability during installation of the hydraulic drive member 40, preventing lateral displacement during horizontal jacking. This also increases the contact area between the hydraulic drive member 40 and the support member 70, thereby enhancing the secure connection. Furthermore, the design of mounting grooves 71 simplifies the installation process of the hydraulic drive member 40. Workers only need to place the hydraulic drive member 40 into the mounting grooves 71, reducing the need for cranes or other lifting equipment.

[0065] Reference Figure 7 In one embodiment of the present invention, the supporting member 70 is further provided with a material-reducing groove 73 along the vertical direction.

[0066] In this embodiment, the design of the material-reducing grooves 73 reduces the material usage of the support member 70, thereby reducing its overall weight and facilitating handling and installation. Despite this weight reduction, the careful design of the position and size of the material-reducing grooves 73 ensures that the support member 70 still has sufficient structural strength to support the hydraulic drive unit 40. The material-reducing grooves 73 also improve air circulation around the support member 70, helping to dissipate heat from the hydraulic drive unit 40 during extended operation.

[0067] Reference Figure 6In one embodiment of the present invention, the reaction support 3 includes a reaction beam 31 and an abutment plate 33. One side of the abutment plate 33 is connected to the reaction beam 31, and the other side is connected to the supporting member 70. The hydraulic drive member 40 is limited to the abutment plate 33 in the horizontal direction.

[0068] In this embodiment, the combined design of the reaction beam 31 and the abutment plate 33 enhances the stability of the entire system, ensuring that the structure does not shake during horizontal jacking. The hydraulic drive member 40 can directly interface with the abutment plate 33 end-to-end, simplifying installation and reducing the need for auxiliary equipment.

[0069] Reference Figure 6 In one embodiment of the present invention, a third reinforcing rib 331 is protruded from the side of the abutting plate 33 facing away from the supporting member 70 , and the bottom end of the third reinforcing rib 331 is also connected to the reaction beam 31 .

[0070] In this embodiment, the design of the third reinforcing rib 331 can enhance the structural strength of the abutment plate 33, ensuring that the abutment plate 33 will not deform or be damaged when subjected to the large load of the hydraulic drive member 40. Furthermore, by connecting the bottom end of the third reinforcing rib 331 to the reaction beam 31, the stability of the entire reaction support 3 structure is further enhanced, reducing shaking during movement.

[0071] In summary, the building jacking device 100 of the embodiment of the present invention mainly has the following beneficial effects: a pair of small roller members 51 for auxiliary rolling are added under the support roller 60, which reduces the friction resistance of the building 93 during the jacking process. A supporting portion 251 is provided on the side wall of the limiting groove 25, and the supporting portion 251 is used to temporarily support the reaction support 3, simplifying the hoisting process of the reaction support 3 and playing a role of temporary fixation before the formal jacking. A supporting member 70 is also provided on one side of the reaction support 3, and is integrated with the reaction support 3. The supporting member 70 is migrated synchronously with the reaction support 3 and can be used for temporary positioning and support of the hydraulic drive member 40. Therefore, the building jacking device 100 of the embodiment of the present invention helps to simplify the construction steps and improve construction efficiency.
