[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1: Reference Figures 1-7 A guide rail support base device for an intelligent lifting platform door includes: a multi-layer alloy lifting base 1, a linear bearing 2, a main shaft structure 3, and a connecting component 4. The top of the multi-layer alloy lifting base 1 is equipped with the linear bearing 2, and the main shaft structure 3 is slidably connected inside the linear bearing 2. The bottom of the multi-layer alloy lifting base 1 is connected to the civil foundation through the connecting component 4.

[0028] The principles and beneficial effects of the above scheme are as follows:

[0029] The civil engineering foundation is buried underground and connected to the connecting component 4. The connecting component 4 is connected to the bottom of the multi-layer alloy lifting base 1. The multi-layer alloy lifting base 1 is connected to a linear bearing 2. The specific model of the linear bearing 2 is: LMF series. When the integrated crossbeam moves, the main shaft structure 3 connected to its bottom moves synchronously. The main shaft structure 3 is slidably connected to the linear bearing 2, which increases the stability of the main shaft structure 3 when it moves. By setting the multi-layer alloy lifting base 1 to be connected to the civil engineering foundation through the connecting component 4, the complexity of the device during installation and disassembly is greatly reduced, and the convenience of on-site installation and maintenance of the device is improved.

[0030] The multi-layer alloy lifting base 1 is specifically a composite material structure composed of multiple layers of different metals or alloys, each layer having different physical, chemical, or mechanical properties. The multi-layer alloy is specifically made by methods such as physical vapor deposition, chemical vapor deposition, electroplating, thermal spraying, and powder metallurgy in the existing technology. By setting the multi-layer alloy lifting base 1, the stability and safety of the device during operation can be increased through its extremely excellent pressure resistance and corrosion resistance characteristics.

[0031] Example 2: Reference Figures 1-7 The connecting component 4 includes: an internal threaded tube 5, a bolt 6, a retaining ring 7, and an embedded spindle protective sleeve 8. An internal threaded tube 5 is inserted into the round hole at the bottom of the multi-layer alloy lifting base 1. The internal threaded tube 5 is threadedly connected to the multi-layer alloy lifting base 1 by the bolt 6. The internal threaded tube 5 is threadedly connected to the threaded part at the top of the embedded spindle protective sleeve 8. The embedded spindle protective sleeve 8 is connected to the civil engineering foundation.

[0032] The principles and beneficial effects of the above scheme are as follows:

[0033] The embedded spindle protective sleeve 8 is connected to the civil engineering foundation. When it is necessary to install the multi-layer alloy lifting base 1, it is only necessary to adjust the concentricity of the inner threaded tube 5, and then rotate the multi-layer alloy lifting base 1. The installation of the multi-layer alloy lifting base 1 is completed by threading the inner threaded tube 5 with the threaded part at the top of the embedded spindle protective sleeve 8. This greatly improves the speed of installation and disassembly of the multi-layer alloy lifting base 1.

[0034] When the spindle protection sleeve 8 changes according to the actual construction conditions, the inner diameter of the inner threaded tube 5 needs to be adjusted accordingly. At this time, the bolt 6 can be loosened to remove the old inner threaded tube 5 from the multi-layer alloy lifting base 1, and a new inner threaded tube 5 with a suitable inner diameter can be installed on the multi-layer alloy lifting base 1. The bolt 6 is then tightened again to complete the installation of the inner threaded tube 5, which greatly improves the adaptability of the device to different working conditions during use.

[0035] Example 3: Reference Figures 1-7The top of the embedded spindle protective sleeve 8 contacts and engages with the bottom of the retaining ring 7, and the retaining ring 7 is fixed to the top of the inner threaded tube 5.

[0036] The principles and beneficial effects of the above scheme are as follows:

[0037] During the installation of the internal threaded tube 5 onto the embedded spindle protective sleeve 8, after the top of the embedded spindle protective sleeve 8 contacts and engages with the bottom of the retaining ring 7, the retaining ring 7 limits the top of the embedded spindle protective sleeve 8 to prevent the length of the embedded spindle protective sleeve 8 installed inside the multi-layer alloy lifting base 1 from being too large.

[0038] Example 4: Reference Figures 1-7 The main spindle structure 3 includes a lifting spindle 9 and a sealing column 10. The linear bearing 2 is slidably connected to the lifting spindle 9. The bottom of the lifting spindle 9 is connected to the sealing column 10. The diameter of the lifting spindle 9 is smaller than the diameter of the sealing column 10. The diameter of the sealing column 10 is smaller than the inner diameter of the embedded spindle protective sleeve 8.

[0039] The principles and beneficial effects of the above scheme are as follows:

[0040] The top of the lifting spindle 9 is connected to the bottom of the integrated crossbeam. The sealing column 10 is installed at the bottom of the lifting spindle 9, and the diameter of the sealing column 10 is smaller than the inner diameter of the embedded spindle protective sleeve 8. Therefore, the embedded spindle protective sleeve 8 can store the lifting spindle 9, making full use of the space inside the device.

[0041] Example 5: Reference Figures 1-7 The bottom of the linear bearing 2 contacts and engages with the top of the sealing column 10, and the sealing column 10 is placed inside the multi-layer alloy lifting base 1.

[0042] The principles and beneficial effects of the above scheme are as follows:

[0043] When the lifting spindle 9 moves upward too far, the bottom of the linear bearing 2 contacts and engages with the top of the sealing column 10 to limit the lifting spindle 9, preventing the lifting spindle 9 from dislodging from the linear bearing 2 and improving the safety of the device during use.

[0044] Example 6: Reference Figures 1-7 The multi-layer alloy lifting base 1 is connected to a locking cylinder 11 on its side. The output shaft of the locking cylinder 11 is slidably connected to the multi-layer alloy lifting base 1. The end of the output shaft of the locking cylinder 11, which is placed inside the multi-layer alloy lifting base 1, is rotatably connected to a locking wheel 12. The side wall of the locking wheel 12 is in contact with the bottom of the sealing column 10.

[0045] The principles and beneficial effects of the above scheme are as follows:

[0046] When the lifting spindle 9 rises to its limit position, the locking cylinder 11 can be activated. The output shaft of the locking cylinder 11 drives the locking wheel 12 to move. After the locking wheel 12 rubs against the bottom of the sealing column 10, it can provide support for the sealing column 10 and lock it, preventing the lifting spindle 9 from accidentally falling off. Since the locking wheel 12 is rotatably connected to the output shaft of the locking cylinder 11, the locking wheel 12 will not generate severe friction on the bottom of the sealing column 10 after contacting it, thus extending the service life of the locking wheel 12.

[0047] Example 7: Reference Figures 1-7 It also includes: a positioning mechanism 13; the positioning mechanism 13 includes: a rod 14 and a sleeve 15, the bottom of the rod 14 is hinged to the output shaft of the locking cylinder 11, the top of the rod 14 is concentrically arranged with the sleeve 15, the bottom of the sleeve 15 is equipped with a limit ring 22, the top of the limit ring 22 is in contact with the bottom of the limit plate 23, the limit plate 23 is installed on the top of the rod 14, the rod 14 is slidably connected to the limit ring 22, and the top of the sleeve 15 is hinged to the inner wall of the multi-layer alloy lifting base 1.

[0048] The bottom of the insertion rod 14 is positioned away from the locking cylinder 11.

[0049] The principles and beneficial effects of the above scheme are as follows:

[0050] When the output shaft of the locking cylinder 11 extends, the insertion rod 14 moves downward within the sleeve 15. When the output shaft of the locking cylinder 11 retracts, the insertion rod 14 moves upward within the sleeve 15. When the output shaft of the locking cylinder 11 drives the locking wheel 12 to perform the locking action, the top of the limiting ring 22 contacts and engages with the bottom of the limiting disc 23 to prevent the insertion rod 14 from disengaging from the sleeve 15 and to prevent the output shaft of the locking cylinder 11 from deforming due to excessive force.

[0051] Example 8: Reference Figures 1-7 The multi-layer alloy lifting base 1 is internally connected to a liquid pump 16, and a high-elastic rubber guide wheel 17 is connected to the rotating shaft of the liquid pump 16. The side wall of the high-elastic rubber guide wheel 17 is in frictional engagement with the side wall of the lifting main shaft 9.

[0052] The principles and beneficial effects of the above scheme are as follows:

[0053] Since the high-elasticity rubber guide wheel 17 is mounted on the rotating shaft of the liquid pump 16, the movement of the lifting main shaft 9 can drive the high-elasticity rubber guide wheel 17 to rotate. The high-elasticity rubber guide wheel 17 can provide auxiliary guidance for the lifting main shaft 9, improving the stability of the lifting main shaft 9 in the linear direction. Since the high-elasticity rubber guide wheel 17 is made of nitrile rubber, it has extremely high elasticity. When the lifting main shaft 9 moves upward into position, the lifting main shaft 9 ends the frictional engagement with the high-elasticity rubber guide wheel 17. After being squeezed by the sealing column 10, the high-elasticity rubber guide wheel 17 deforms and finally contacts the side of the sealing column 10 without getting stuck between the sealing column 10 and the linear bearing 2. When the lifting main shaft 9 moves downward, the high-elasticity rubber guide wheel 17 ends the contact engagement with the side of the sealing column 10. Under the action of its elasticity, the high-elasticity rubber guide wheel 17 returns to its initial shape and rubs against the side of the lifting main shaft 9 again, ensuring that the lifting main shaft 9 has excellent stability when moving and enabling the components in the device to work repeatedly.

[0054] Example 9: Reference Figures 1-7 The linear bearing 2 has a mounting hole and a second mounting hole on its inner wall. Both mounting holes are located between two rolling elements inside the linear bearing 2. The mounting hole is connected to the end of pipe 18. The other end of pipe 18 is connected to the end of storage tank 19. Storage tank 19 is filled with lubricating oil. The other end of storage tank 19 is connected to the end of pipe 20. The other end of pipe 20 is connected to the side of liquid pump 16. The other side of liquid pump 16 is connected to the end of pipe 3 21. The other end of pipe 3 21 is connected to mounting hole 2. Pipe 18 is located above pipe 3 21.

[0055] The principles and beneficial effects of the above scheme are as follows:

[0056] When the high-elastic rubber guide wheel 17 rotates in the forward direction, the hydraulic oil in the linear bearing 2 enters the hydraulic pump 16 from the pipe 3 21, and then enters the storage tank 19 through the pipe 2 20 connected to the hydraulic pump 16, and then enters the pipe 18 through the storage tank 19.

[0057] When the high-elasticity rubber guide wheel 17 rotates in the reverse direction, the hydraulic oil in the linear bearing 2 enters the storage tank 19 through the pipe 18, then enters the liquid pump 16 through the second pipe 20, enters the third pipe 21 through the liquid pump 16, and finally enters the linear bearing 2 through the third pipe 21. Since the pipe 18 is located above the third pipe 21, the device can circulate the lubricating oil in the linear bearing 2 from top to bottom or from bottom to top when the high-elasticity rubber guide wheel 17 rotates. At the same time, the lubricating oil is circulated between the linear bearings 2 to prevent wear and extend the service life of the device.

[0058] As can be seen from the existing technology, the rolling friction provided by the linear bearing 2 is achieved by its internal rolling elements. Therefore, by setting both the mounting hole and the second mounting hole between the two rolling elements inside the linear bearing 2, the circulation of lubricating oil can be guaranteed, and the hole structure can be avoided from damaging the rolling elements, thus improving the rationality of the device.

[0059] Example 10: Reference Figures 1-7 The output shaft of the locking cylinder 11 is connected to the bottom end of the long side of the L-shaped limiting rod 24, and the bottom of the short side of the L-shaped limiting rod 24 contacts and engages with the top edge of the sealing column 10.

[0060] The principles and beneficial effects of the above scheme are as follows:

[0061] An L-shaped limiting rod 24 is connected to the output shaft of the locking cylinder 11, and the bottom of the short side of the L-shaped limiting rod 24 contacts and engages with the top edge of the sealing column 10, which increases the locking effect of the mechanism and further increases the stability of the device when locking.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
