Detailed implementation manners

[0028] The following further describes the present invention in detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0029] It should be understood that terms such as "having", "comprising", and "including" as used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0030] As Figures 1 - 5 shown, the present invention provides a more stable electric rail alignment device, which is composed of a fixed rail part arranged on a transfer platform and a moving rail part arranged on a lift platform, and includes: at least two docking supports and a docking component 2;

[0031] At least one docking support is arranged on the moving rail part and serves as a moving rail support 1a;

[0032] At least one docking support is arranged on the fixed rail part and serves as a fixed rail support 1b;

[0033] The docking component 2 is arranged on the lift platform. The connecting section 21 of the docking component 2 penetrates through the moving rail support 1a and extends towards the fixed rail support 1b. The moving rail support 1a is always in contact with the connecting section 21, so as to provide position guidance for the connecting section 21 and maintain the connection between the connecting section 21 and the lift platform.

[0034] When docking is required, the connecting section 21 of the docking component 2 extends to the fixed rail support 1b and penetrates through the fixed rail support 1b to achieve connection with the fixed rail support 1b.

[0035] When the docking state needs to be released, the connecting section 21 of the docking component 2 is retracted from the fixed rail support 1b to release the connection state with the fixed rail support 1b.

[0036] The number of fixed rail supports 1b is at least two. Two fixed rail supports 1b can be arranged in parallel in the fixed rail part, and two moving rail supports 1a are correspondingly arranged in the moving rail part. By increasing the number of connections of the connecting section 21, the stability of the elevator at a certain position is further increased. Usually, there is one moving rail support 1a and one docking component 2, and the number of fixed rail supports 1b is two, which are arranged vertically. The two fixed rail supports 1b are respectively located at the highest point and the lowest point of the lifting of the elevator platform, as Figure 1 shown. Thus, whether the elevator platform is at the highest point or the lowest point, the moving rail support 1a and the fixed rail support 1b can be connected through the connecting section 21 of the docking component 2, so as to stably fix the elevator and reduce the up and down rebound and shaking during the process of transporting workpieces after the elevator platform stops.

[0037] The working principle and beneficial effects of the above technical solution: Through the design of the above structure, a moving rail support 1a is arranged in the moving rail part, and the connecting section 21 is always kept under the guidance of the moving rail support 1a. When the moving rail part and the fixed rail part are docked, the connecting section 21 can be quickly docked with the fixed rail support 1b under the guidance of the moving rail support 1a. The fixed rail support 1b and the moving rail support 1a are connected into one body through the connecting section 21, thereby improving the stability during the transportation process after the elevator stops, reducing shaking, and preventing potential safety hazards caused by program failures.

[0038] Further, as one of many embodiments, the docking support includes a mounting plate 11, a structural frame 12, and at least one set of guiding components. The mounting plate 11 of the moving rail support 1a is connected to the elevator platform, and the mounting plate 11 of the fixed rail support 1b is connected to the hanging platform, thereby realizing the connection between the moving rail support 1a and the elevator platform, and the connection between the fixed rail support 1b and the hanging platform, as Figure 1 shown.

[0039] The structural frame 12 is arranged on the mounting plate 11. The guiding components are arranged on the structural frame 12 and are movably connected to the structural frame 12. A docking channel adapted to the shape of the connecting section 21 of the docking component 2 is arranged on the guiding components, and the guiding components are movably connected to the connecting section 21 of the docking component 2 through the docking channel.

[0040] As one of many embodiments, the guiding assembly is composed of at least three guiding wheels 13. The guiding wheels 13 can not only provide stable support for the connecting section 21 in the radial direction, but also do not affect the axial movement of the connecting section 21. The guiding wheels 13 enclose a docking channel. The guiding wheels 13 are movably connected to the structural frame 12 through rotating shafts. The guiding wheels 13 are in contact with the connecting section 21 of the docking assembly 2. When the connecting section 21 is located in the docking channel, the guiding wheels 13 are attached to the surface of the connecting section 21. The central axis of the rotating shaft of the guiding wheel 13 is normal to the central axis of the connecting section 21. Usually, the guiding wheels 13 are arranged at equal intervals along the circumferential direction of the connecting section 21 with the central axis of the connecting section 21 as the center, so that the contact points between the guiding wheels 13 and the connecting section 21 are evenly distributed on the outer wall of the connecting section 21 along the circumferential direction.

[0041] The number of the guiding wheels 13 can be three. With the central axis of the connecting section 21 as the center of the circle, the central angle between two guiding wheels 13 is 120°. Thus, the guiding assembly can provide radial support for the connecting section 21 and can also provide guidance for the connecting section 21. The docking channel formed by the end faces of the three guiding wheels 13 can be applicable to the connecting section 21 with a circular cross-section and the connecting section 21 with a triangular cross-section.

[0042] Usually, the number of the guiding wheels 13 is four, in a "cross" shape, with two arranged vertically and two arranged horizontally. As Figure 2 shown, the cross-section of the connecting section 21 is usually rectangular. The four guiding wheels 13 are respectively in contact with the four faces of the connecting section 21. Thus, the connecting section 21 can be limited and guided from four directions of up, down, left and right, further improving the stability of the lift platform after docking.

[0043] Usually, the number of the guiding assemblies is two groups and they are arranged in parallel. Taking the example of setting two groups of guiding assemblies, as Figure 2 shown, each face of the connecting section 21 has two guiding wheels 13 in contact with it, thus further improving the stability.

[0044] According to the different numbers, structures and combination modes of the guiding assemblies, the embodiments of the structural frame 12 are also different. As one of many embodiments, taking the example of setting four guiding wheels 13 in a "cross" shape, the structural frame 12 can be composed of four plates with an L-shaped cross-section, which is convenient for the installation of the rotating shafts of the guiding wheels 13; it can also be as Figure 2 shown, composed of several sheet-like plates spliced together, as long as the structural frame 12 can be movably connected to the rotating shafts of the guiding wheels 13.

[0045] Further, if the foregoing implementation of splicing multiple sheet-like plates into the structural frame 12 is adopted, it is necessary to connect the sheet-like plates into a whole. Therefore, a first end plate 14 and a second end plate 15 are provided at both ends of the structural frame 12. The first end plate 14 is parallel to the second end plate 15, and through holes coaxial with the docking channel are provided on both the first end plate 14 and the second end plate 15 to facilitate the entry and exit of the connection section 21.

[0046] Further, the structural frame 12 can be connected to the mounting plate 11 through the first end plate 14 and the second end plate 15, as Figures 2 - 5 shown.

[0047] Further, the docking assembly 2 is composed of the connection section 21 and the telescopic device 22, and the output shaft of the telescopic device 22 can move reciprocally. The telescopic device 22 can be a pneumatic telescopic device (such as a cylinder), a hydraulic telescopic device (such as a hydraulic cylinder, a jack), or a mechanical transmission device (such as a combination of a screw, a motor, and a gear). The output shaft of the telescopic device 22 is connected to one end of the connection section 21, and the other end of the connection section 21 is the docking end 211. The telescopic device 22 is used to drive the connection section 21 to translate along the axis direction of the docking channel.

[0048] Further, since both the moving rail support 1a and the fixed rail support 1b are manually installed and calibrated, there will inevitably be an error between the moving rail support 1a and the corresponding fixed rail support 1b when the lift platform moves to the designated position. In order to achieve rapid docking, the docking end 211 can be set to be conical, and the area of the docking end 211 away from the connection section 21 is smaller than the area of the connection between the docking end 211 and the connection section 21. As Figure 3 shown, during the process of the connection section 21 moving towards the fixed rail support 1b, the docking end 211 can enter the docking channel of the fixed rail support 1b through the conical surface, and then the guiding wheel 13 contacts the conical surface of the docking end 211 to adjust the position of the docking end 211 in the docking channel. Finally, all the guiding wheels 13 are in contact with the surface of the connection section 21 to complete the rapid docking.

[0049] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention.

[0050] In the present invention, unless otherwise clearly stipulated and defined, terms such as "installed", "connected", "joined", "fixed", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

It can be fully applied to various fields suitable for the present invention. For those who are familiar with the field, additional modifications can be easily achieved.
