Description

Technical Field

[0001] This utility model relates to the field of lifting mechanisms for eccentric lifting platforms combined with telescopic forks, and particularly to a T-shaped guide rail lifting and guiding mechanism. Background Technology

[0002] In recent years, with the continuous expansion of the logistics industry, logistics management methods and technologies have been constantly improving. Shortening logistics time, saving logistics costs, improving logistics efficiency, and rationalizing logistics organization are common characteristics of logistics development in economically developed countries. Currently, modern logistics infrastructure exists, and automated storage and retrieval systems (AS / RS) are an important component of modern logistics systems, widely used in various industries. With the development of various industries, the types of goods are becoming increasingly complex, with vastly different shapes and dimensions. This has created an increasing demand from customers for the height adjustment function of lifting forks.

[0003] The existing T-shaped guide rails in lifting mechanisms, made of ordinary aluminum, have significant problems. During long-term use, the properties of aluminum result in poor wear resistance, making it prone to wear and deformation. This leads to decreased guiding accuracy and failure of the guiding function, severely impacting the normal operation of cargo handling and storage. Furthermore, ordinary aluminum guide rails have poor versatility and are difficult to adapt to different specifications of T-shaped guide rails, making their limitations increasingly apparent in diverse application scenarios.

[0004] Therefore, it is urgent to develop a guiding mechanism that is simple in structure, reliable in quality, and can flexibly adapt to T-shaped guide rails of different specifications. This is of great significance for improving the overall performance of cargo handling and storage equipment and meeting the diversified needs of the market. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a T-shaped guide rail lifting and guiding mechanism.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A T-shaped guide rail lifting and guiding mechanism includes a guide assembly connected to the web of the T-shaped guide rail. The guide assembly includes a guide mounting seat that is driven and connected to a lifting platform. The guide mounting seat has a sliding groove. The web is slidably engaged with the guide mounting seat through the sliding groove. A first guide block is installed at the bottom of the sliding groove, and second guide blocks are installed on the two side walls of the sliding groove. The first guide block and the second guide block are respectively in close contact with the upper surface and two side surfaces of the web of the T-shaped guide rail.

[0008] A limiting plate is installed at the top of the chute, and the limiting plate cooperates with the second guide block to restrict the lateral movement of the T-shaped guide rail;

[0009] The base plate of the T-shaped guide rail is mounted on the guide rail mounting base.

[0010] Furthermore, the guide rail mounting base has an L-shaped structure, including a first mounting plate arranged in the vertical direction and a second mounting plate arranged in the horizontal direction;

[0011] The first mounting plate has a plurality of mounting holes arranged in an array, and the base plate of the T-shaped guide rail has fixing holes corresponding to the mounting holes. The first mounting plate and the base plate are fixedly connected by bolts passing through the mounting holes and the fixing holes.

[0012] The width of the first mounting plate is adapted to the width of the base plate to form a surface contact fixation.

[0013] Furthermore, a triangular reinforcing plate is installed at the angle between the first mounting plate and the second mounting plate, and the two right-angled sides of the reinforcing plate are welded or bolted to the first mounting plate and the second mounting plate, respectively.

[0014] Furthermore, the first guide block is fixed to the bottom of the groove by a first screw.

[0015] Furthermore, the second guide block is fixed to the groove wall of the slide by a second screw.

[0016] Furthermore, the limiting plate is a long strip of metal plate with the same length as the slide groove, and is evenly fixed to the top edge of the slide groove by a third screw.

[0017] Furthermore, both the first guide block and the second guide block are made of wear-resistant polymer material.

[0018] Furthermore, the limiting plate has chamfers at both ends.

[0019] Compared with existing technologies, the advantages of this invention are as follows: By setting a first guide block on the bottom wall of the guide mounting seat's groove and second guide blocks on both side walls, the web of the T-shaped guide rail is limited, effectively eliminating the possibility of lateral movement of the guide mechanism. This allows for reliable long-term use in enclosed, non-maintenance environments, significantly improving stability and guiding accuracy during lifting. By adjusting the guide block specifications, groove dimensions, or guide rail mounting seat structure, T-shaped guide rails with different cross-sectional dimensions can be flexibly adapted. Selecting T-shaped guide rails of different lengths can meet different lifting height requirements, significantly improving the adaptability of the mechanism to various application scenarios.

[0027] The technical solution of this utility model will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] See appendix Figures 1-4 As shown, a T-shaped guide rail lifting and guiding mechanism of this application includes a guide assembly 2 connected to the web 11 of the T-shaped guide rail 1. The guide assembly 2 includes a guide mounting seat 21 driven and connected to the lifting platform. A sliding groove 22 is provided on the guide mounting seat 21. The web 11 slides and engages with the guide mounting seat 21 through the sliding groove 22. A first guide block 23 is installed at the bottom of the sliding groove 22. Second guide blocks 24 are installed on the two side walls of the sliding groove 22. The first guide block 23 and the second guide block 24 are respectively in close contact with the upper surface and the two side surfaces of the web 11 of the T-shaped guide rail. A limiting plate 25 is installed at the top of the sliding groove 22. The limiting plate 25 cooperates with the second guide block 24 to restrict the lateral movement of the T-shaped guide rail 1. The bottom plate 12 of the T-shaped guide rail 1 is installed on the guide rail mounting seat 3.

[0029] The following provides further explanation of the above structure:

[0030] See appendix Figures 1-4 As shown, the T-shaped guide rail 1 consists of a horizontally arranged base plate 12 and a web plate 11 perpendicular to the base plate 12. The base plate 12 is used to connect with the guide rail mounting seat 3 to provide a stable installation base for the entire guide rail. The web plate 11 cooperates with the guide assembly 2 to realize the guiding function during the lifting process.

[0031] The guide assembly 2 includes a guide mounting base 21, a first guide block 23, a second guide block 24, and a limiting plate 25. The guide mounting base 21 is driven and connected to the lifting platform. A groove 22 is formed on the contact surface between the guide mounting base 21 and the web plate 11 of the T-shaped guide rail 1. The web plate 11 of the T-shaped guide rail 1 can slide within the groove 22, thereby achieving a sliding fit with the guide mounting base 21. The size of the groove 22 is adapted to the size of the web plate 11 of the T-shaped guide rail to ensure that the web plate 11 slides smoothly within the groove 22. The first guide block 23 is fixed to the bottom of the groove 22 by a first screw. To ensure the firmness and stability of the installation, the first screw should be a high-strength internal hexagon socket head cap screw and tightened to the specified torque. The first guide block 23 is made of wear-resistant polymer materials, such as polytetrafluoroethylene, polyoxymethylene, or ultra-high molecular weight polyethylene. These materials possess excellent wear resistance, self-lubrication, and a low coefficient of friction, effectively reducing friction and wear between the guide block and the web 11 surface of the T-shaped guide rail 1, thus extending the service life of the guide block. Simultaneously, the wear-resistant polymer material also exhibits a certain degree of elasticity, absorbing vibrations and impacts generated during lifting. The second guide block 24 is fixed to the two side walls of the slide groove 22 by second screws. Similar to the first guide block 23, the second screws should also be high-strength internal hexagonal head screws, tightened to the specified torque. When installing the second guide block 24, attention should be paid to adjusting the gap between it and the two sides of the web 11. The gap is generally controlled between 0.1-0.3 mm to ensure both good guiding function and to avoid jamming due to excessively small gaps. The second guide block 24 also uses a wear-resistant polymer material, with the same material properties as the first guide block 23. The limiting plate 25 is a long strip of metal plate, the length of which is the same as the length of the slide groove 22. The function of the limiting plate 25 is to cooperate with the second guide block 24 to restrict the lateral movement of the T-shaped guide rail 1. The limiting plate 25 has multiple evenly distributed mounting holes, and it is evenly fixed to the top edge of the slide groove 22 by a third screw. To prevent the limiting plate 25 from loosening during use, a spring washer or a lock nut can be installed on the third screw. Preferably, the limiting plate 25 can be made of stainless steel or carbon steel to ensure that it has sufficient strength and rigidity. At the same time, in order to improve the corrosion resistance of the limiting plate 25, its surface can be galvanized or painted. This application forms a bottom support and two-sided constraint on the web plate 11 of the T-shaped guide rail by setting a first guide block 23 on the bottom wall of the slide groove 22 of the guide mounting seat 21 and setting second guide blocks 24 on both side walls. This can effectively eliminate the possibility of the guide mechanism moving left and right, significantly improve the stability and guiding accuracy during the lifting process, and is suitable for scenarios with high requirements for motion accuracy.

[0032] The guide rail mounting base 3 has an L-shaped structure, including a first mounting plate 31 arranged vertically and a second mounting plate 32 arranged horizontally. The first mounting plate 31 has multiple arrayed mounting holes, and the base plate 12 of the T-shaped guide rail 1 has corresponding fixing holes. Bolts are inserted through the mounting holes and fixing holes to fix the first mounting plate 31 to the base plate 12 of the T-shaped guide rail 1. The width of the first mounting plate 31 matches the width of the base plate 12 of the T-shaped guide rail 1, forming a surface contact fixation. This installation method improves the stability of the connection. The second mounting plate 32 mainly serves to support and fix the entire guide rail mounting base 3. A triangular reinforcing plate 33 is installed at the angle between the first mounting plate 31 and the second mounting plate 32. The two right-angled sides of the reinforcing plate 33 are welded or bolted to the first mounting plate 31 and the second mounting plate 32, respectively. The triangular reinforcing plate 33 enhances the rigidity of the guide rail mounting base 3 and reduces deformation when bearing the T-shaped guide rail 1 and lifting loads.

[0033] Preferably, in this embodiment, the non-standard designed guide mounting base 21, first guide block 23, second guide block 24 and limiting plate 25 can be adapted to different types of guide rails, improving the versatility and flexibility of the mechanism.

[0034] For a better option, see the appendix. Figure 3 As shown in this embodiment, the limiting plate 25 has chamfers at both ends to prevent scratching operators or other parts.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
