Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a walking mechanism and 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 drive unit pushes the building horizontally at one end, while the other end is horizontally constrained by a reaction mechanism, allowing the building to shift horizontally on the traveling mechanism.

[0003] In related technologies, the travel mechanism includes a track beam and support rollers, which are horizontally laid on the track beam to support the building. However, when the hydraulic drive element pushes the building horizontally, the support rollers slide against the track beam. As a result, the support rollers are directly subjected to the sliding friction of the track beam, which reacts on the building. Because the sliding friction is generally high, the speed of the building's displacement is reduced, hindering construction efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a walking mechanism, which aims to reduce the friction of a building during the pushing process, ensure the displacement speed of the building, and improve the construction efficiency.

[0005] To achieve the above-mentioned purpose, the utility model proposes a walking mechanism, which is applied to a building pushing device, and the walking mechanism includes a track beam, an auxiliary roller assembly and a support roller. The track beam is installed on the ground; the auxiliary roller assembly is arranged on the side of the track beam away from the ground, and the auxiliary roller assembly has at least one auxiliary shaft, which can be rotatably arranged around an extension direction perpendicular to the track beam; one side of the support roller abuts against the auxiliary shaft in the vertical direction, and the other side of the support roller away from the auxiliary shaft is used to support the building so that the building can be movably arranged in the horizontal direction.

[0006] In one embodiment, the auxiliary roller assembly includes two roller members, which are arranged on the track beam at intervals along the horizontal direction. The two roller members respectively have an auxiliary shaft, and the two auxiliary shafts are respectively in contact with two sides of the supporting roller.

[0007] In one embodiment, the roller member includes two mounting seats and an auxiliary shaft. The two mounting seats are respectively connected to the track beam and are spaced apart perpendicular to the extension direction of the track beam. The two ends of the auxiliary shaft are respectively rotatably connected to the two mounting seats.

[0008] In one embodiment, the mounting seat is welded to the track beam.

[0009] In one embodiment, the diameters of the two auxiliary shafts are smaller than the diameter of the supporting roller.

[0010] In one embodiment, the walking mechanism also includes a stop assembly, the stop assembly includes two stop members, the two stop members are arranged on the track beam at intervals along the horizontal direction, the two stop members and the track beam are combined to form a limiting groove, and the auxiliary roller assembly and the support roller are arranged in the limiting groove.

[0011] In one embodiment, a first reinforcing rib is protruded from a side of the stopper facing away from the auxiliary roller assembly, and a bottom end of the first reinforcing rib is also connected to the track beam.

[0012] In one embodiment, the auxiliary roller assembly and the supporting roller are both provided in plurality, and the plurality of auxiliary roller assemblies are equidistantly spaced on the track beam along a horizontal direction.

[0013] In one embodiment, the track beam, the auxiliary roller assembly, and the support roller are respectively arranged at intervals of two in a direction perpendicular to the extension direction of the track beam, and one auxiliary roller assembly is arranged on one side of the track beam.

[0014] The present utility model also proposes a building pushing device, which includes a reaction support, a hydraulic drive component and the walking mechanism as described above, wherein the reaction support is limited to the track beam along the horizontal direction; one side of the hydraulic drive component is used to horizontally push the building, and the other side is horizontally limited to the reaction support.

[0015] In the technical solution of the present invention, the walking mechanism includes a track beam, an auxiliary roller assembly and a support roller. The auxiliary roller assembly is laid flat on the track beam in the horizontal direction, and is used to provide rolling support for the support roller through the auxiliary shaft. The side of the support roller facing away from the auxiliary shaft is used to support the building.

[0016] It is worth noting that in the process of the hydraulic drive component pushing the building horizontally, the support roller is in rolling contact with the auxiliary shaft. Therefore, the support roller is directly subjected to the rolling friction of the auxiliary shaft and reacts to the building. Since the value of the rolling friction is much smaller than the sliding friction, the normal displacement speed of the building can be guaranteed, which is conducive to improving construction efficiency.

[0026] 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 creative efforts shall fall within the scope of protection of the present invention.

[0027] 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. If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme in which A and B are satisfied at the same time. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. 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.

[0029] 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 restrained by a reaction mechanism, allowing the building to shift horizontally on the traveling mechanism.

[0030] In related technologies, the travel mechanism includes a track beam and support rollers, which are horizontally laid on the track beam to support the building. However, when the hydraulic drive element pushes the building horizontally, the support rollers slide against the track beam. As a result, the support rollers are directly subjected to the sliding friction of the track beam, which reacts on the building. Because the sliding friction is generally high, the speed of the building's displacement is reduced, hindering construction efficiency.

[0031] In order to solve the above problems, the present invention proposes a walking mechanism 10, which aims to reduce the friction of the building 93 during the pushing process, ensure the displacement speed of the building 93, and improve construction efficiency.

[0032] Reference Figures 1 to 6 In one embodiment of the present utility model, the walking mechanism 10 is applied to a building pushing device 100, and the walking mechanism 10 includes a track beam 1, an auxiliary roller assembly 2 and a support roller 3. The track beam 1 is installed on the ground; the auxiliary roller assembly 2 is arranged on the side of the track beam 1 away from the ground, and the auxiliary roller assembly 2 has at least one auxiliary shaft 213, and the auxiliary shaft 213 is rotatable around an extension direction perpendicular to the track beam 1; one side of the support roller 3 is in contact with the auxiliary shaft 213 in the vertical direction, and the other side of the support roller 3 away from the auxiliary shaft 213 is used to support the building 93, so that the building 93 can be movably arranged in the horizontal direction.

[0033] The track beam 1 is a key component of the traveling mechanism 10. It is typically connected to pre-installed fasteners for ground installation, providing support and guidance for the entire building pushing device 100. An underpinning beam 91 is installed at the bottom of the building 93. This underpinning beam 91 serves as a stable platform for the movement of the building 93, reducing vibration and sway during movement and improving the smoothness of the movement.

[0034] In the technical solution of the present invention, the walking mechanism 10 includes a track beam 1, an auxiliary roller assembly 2 and a support roller 3. The auxiliary roller assembly 2 is laid flat on the track beam 1 in the horizontal direction, and is used to provide rolling support for the support roller 3 through the auxiliary shaft 213. The side of the support roller 3 facing away from the auxiliary shaft 213 is used to support the building 93.

[0035] It is worth noting that in the process of the hydraulic drive component 60 horizontally pushing the building 93, the support roller 3 is in rolling contact with the auxiliary shaft 213, so the support roller 3 is directly subjected to the rolling friction force of the auxiliary shaft 213 and reacts to the building 93. Since the value of the rolling friction force is much smaller than the sliding friction force, the normal displacement speed of the building 93 can be guaranteed, which is conducive to improving construction efficiency.

[0036] Optionally, a fixed seat is provided on the track beam 1 , and the support roller 3 is integrally rotatably connected to the fixed seat, thereby further achieving rolling contact with the track beam 1 .

[0037] Reference Figure 3 and Figure 4In one embodiment of the present invention, the auxiliary roller assembly 2 includes two roller members 21, and the two roller members 21 are arranged at intervals on the track beam 1 along the horizontal direction. The two roller members 21 respectively have an auxiliary shaft 213, and the two auxiliary shafts 213 respectively abut against the two sides of the support roller 3.

[0038] In this embodiment, two auxiliary shafts 213 are supported on either side of the support roller 3, thereby improving the stability of the building during movement and reducing the risk of deflection. The rolling contact between the two auxiliary shafts 213 and the support roller 3 significantly reduces friction compared to traditional sliding contact, thereby improving movement efficiency.

[0039] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the roller member 21 includes two mounting seats 211 and an auxiliary shaft 213. The two mounting seats 211 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 213 are respectively rotatably connected to the two mounting seats 211.

[0040] In this embodiment, the auxiliary shaft 213 is secured by two mounting brackets 211, ensuring the stability of the auxiliary shaft 213 and, in turn, the stable support of the support roller 3. The design of the mounting brackets 211 makes the auxiliary shaft 213 easy to install and replace, facilitating rapid on-site assembly and subsequent maintenance. The rotational connection between the auxiliary shaft 213 and the mounting brackets 211 at both ends reduces friction between the auxiliary shaft 213 and the mounting brackets 211, thereby extending its service life.

[0041] Optionally, the auxiliary shaft 213 is provided with an axial hole along the axial direction, the shaft core 2131 is passed through the axial hole, and both ends are rotatably connected to the mounting seat 211 through bearings. The mounting seat 211 and the auxiliary shaft 213 are designed as a standardized module to facilitate mass production and rapid on-site assembly.

[0042] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the mounting seat 211 is welded to the track beam 1 .

[0043] In this embodiment, welding, as a strong connection method, can significantly improve the connection strength between the mounting base 211 and the track beam 1, ensuring the structural stability of the entire running mechanism 10 during movement. The welding connection method simplifies the installation process and avoids the complicated installation steps caused by using fasteners such as bolts.

[0044] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the diameters of the two auxiliary shafts 213 are both smaller than the diameter of the supporting roller 3 .

[0045] In this embodiment, the auxiliary shaft 213 has a smaller diameter, reducing the contact area with the support roller 3. This reduces frictional resistance between the two and improves the efficiency of moving the building 93. This reduced friction also reduces the required driving force, helping to reduce energy consumption and improve economic efficiency. The smaller diameter of the auxiliary shaft 213 also helps reduce the wobble of the support roller 3, improving smoothness during movement.

[0046] Reference Figure 5 In one embodiment of the present utility model, the walking mechanism 10 also includes a stop assembly 4, the stop assembly 4 includes two stop members 41, the two stop members 41 are arranged at intervals on the track beam 1 along the horizontal direction, the two stop members 41 and the track beam 1 are enclosed to form a limiting groove 45, and the auxiliary roller assembly 2 and the support roller 3 are arranged in the limiting groove 45.

[0047] In this embodiment, the design of the limiting groove 45 helps ensure the positional accuracy of the auxiliary roller assembly 2 and the support roller 3, thereby ensuring the stability and safety of the building 93 during movement. The provision of the limiting groove 45 increases the safety of the entire traveling mechanism 10 and reduces safety accidents caused by the support roller 3 accidentally deviating from the track.

[0048] Optionally, a position sensor is provided on the stopper 41 to monitor the position status of the auxiliary roller assembly 2 and the support roller 3 in real time to ensure safety during the movement.

[0049] Reference Figure 5 In one embodiment of the present invention, a first reinforcing rib 411 is protruded from the side of the stopper 41 away from the auxiliary roller assembly 2 , and the bottom end of the first reinforcing rib 411 is also connected to the track beam 1 .

[0050] In this embodiment, the provision of first reinforcing ribs 411 enhances the structural strength of stopper 41 and improves its load-bearing capacity, particularly its stability and durability when bearing the weight of building 93. Providing first reinforcing ribs 411 on stopper 41 increases the rigidity of stopper 41, helps maintain the shape of retaining slot 45 stable, and reduces the risk of deformation.

[0051] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the auxiliary roller assembly 2 and the supporting roller 3 are both provided in plurality, and the plurality of auxiliary roller assemblies 2 are arranged on the track beam 1 at equal intervals in the horizontal direction.

[0052] In this embodiment, the multiple auxiliary roller assemblies 2 can share the weight of the building 93 more evenly, avoid a single supporting point from bearing excessive load, and reduce the shaking of the building 93 during movement.

[0053] Optionally, the auxiliary roller assembly 2 is equipped with a suitable lubrication system to reduce friction and wear and improve movement efficiency.

[0054] Reference Figure 1 and Figure 2 In one embodiment of the present utility model, the track beam 1, the auxiliary roller assembly 2 and the support roller 3 are respectively arranged at intervals of two along the extension direction perpendicular to the track beam 1, and one auxiliary roller assembly 2 is arranged on one side of the track beam 1.

[0055] In this embodiment, by arranging the track beam 1, the auxiliary roller assembly 2 and the support roller 3 on both sides of the building 93, the weight of the building 93 can be distributed more evenly, reducing the problem of excessive force on one side, thereby improving the lateral stability of the building 93 during movement.

[0056] Reference Figure 1 and Figure 2 The present invention also proposes a building pushing device 100, which includes a reaction support 50, a hydraulic drive component 60 and the walking mechanism 10 as described above. The reaction support 50 is limited to the track beam 1 along the horizontal direction; one side of the hydraulic drive component 60 is used to horizontally push the building 93, and the other side is horizontally limited to the reaction support 50.

[0057] Among them, since the walking mechanism 10 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0058] The reaction support 50 serves as the rear anchor beam of the hydraulic drive component 60 . When squeezed by the hydraulic drive component 60 , the reaction support 50 applies a force to push back the hydraulic drive component 60 , thereby serving as a horizontal limit for the hydraulic drive component 60 .

[0059] Reference Figure 6 In one embodiment of the present invention, the building pushing device 100 also includes a supporting member 70, which is connected to one side of the reaction support 50 in the horizontal direction; the hydraulic drive member 60 is supported on the supporting member 70 in the vertical direction and is limited to the reaction support 50 in the horizontal direction, and the side of the hydraulic drive member 4 away from the reaction support 50 is used to push the building 93 horizontally.

[0060] The hydraulic drive member 60 includes a base 61 and a telescopic portion 63. The base 61 is placed on the supporting member 70. The telescopic portion 63 is driven by hydraulic pressure to extend and retract to achieve the jacking of the building 93. For example, the hydraulic drive member 60 is selected as a hydraulic jack.

[0061] In this embodiment, the reaction support 50 is horizontally restrained by the track beam 1, and the hydraulic drive unit 60 is vertically supported by the support member 70. When the hydraulic drive unit 60 is used to horizontally push the building 93, the reaction support 50 can horizontally restrain the hydraulic drive unit 60. It is worth noting that before the hydraulic drive unit 60 performs the pushing operation, since the reaction support 50 is supported by the track beam 1, the support member 70 can be used to temporarily position and support the hydraulic drive unit 60, thereby avoiding the continuous occupation of the crane as a construction component, thereby reducing construction costs and improving construction efficiency.

[0062] Reference Figure 6 In one embodiment of the present utility model, the reaction support 50 includes a reaction beam 51 and an abutment plate 53. One side of the abutment plate 53 is connected to the reaction beam 51, and the other side is connected to the supporting member 451. The hydraulic drive member 60 is limited to the abutment plate 53 in the horizontal direction.

[0063] In this embodiment, the combined design of the reaction beam 51 and the abutment plate 53 enhances the stability of the entire system, ensuring that the structure does not shake during horizontal jacking. The hydraulic drive member 60 can directly interface with the abutment plate 53 end-to-end, simplifying installation and reducing the need for auxiliary equipment.

[0064] Reference Figure 6 In one embodiment of the present invention, a second reinforcing rib 531 is protruded from the side of the abutting plate 53 away from the supporting member 451 , and the bottom end of the second reinforcing rib 531 is also connected to the reaction beam 51 .

[0065] In this embodiment, the design of the second reinforcing rib 531 can enhance the structural strength of the abutment plate 53, ensuring that the abutment plate 53 will not deform or be damaged when subjected to the large load of the hydraulic drive member 60. Furthermore, by connecting the bottom end of the second reinforcing rib 531 to the reaction beam 51, the stability of the entire reaction support 50 structure is further enhanced, reducing shaking during movement.

[0066] Reference Figure 5 In one embodiment of the present invention, a supporting portion 451 is provided on the side wall of the limiting groove 45; a limiting member 55 is provided on one side of the reaction force bracket 3, and the limiting member 55 abuts against the supporting portion 451 in the vertical direction and is limited to the groove wall of the limiting groove 45 in the horizontal direction.

[0067] In this embodiment, when the hydraulic drive member 60 is used to horizontally push the building 93, the reaction support 3 can horizontally limit the hydraulic drive member 60 and apply a corresponding reverse thrust force. It is worth noting that when temporarily placing the reaction support 50 in the limiting groove 45, the supporting portion 451 is formed on the groove wall of the limiting groove 45, and the reaction support 50 can be directly temporarily supported by the supporting portion 451. This avoids the need for manually placing a pad in the limiting groove 45, reduces the number of manual operations, and thus helps improve construction efficiency.

[0068] Reference Figure 5 In one embodiment of the present invention, a third reinforcing rib 551 is protruded from one side of the limiting member 55 along the horizontal direction, and the bottom end of the third reinforcing rib 551 is also connected to the reaction support 50.

[0069] In this embodiment, a third reinforcing rib 551 is provided on one side of the limit member 55 along the horizontal direction, and the bottom end of the third reinforcing rib 551 is connected to the reaction support 50. Such a design can improve the structural strength of the limit member 55 and reduce the deformation of the limit member 55 during the pushing process, thereby being beneficial to the stability of the reaction support 50 and the entire building pushing device 100.

[0070] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
