Description

Technical Field

[0001] This utility model belongs to the field of elevator guide rail technology, specifically relating to a guide rail base. Background Technology

[0002] In the elevator industry, guide rail bases are used to support and fix the guide rails. They typically include a base plate 1 fixed to the ground and a guide rail fixing plate 2 fixed to the guide rails, such as... Figure 1 , Figure 2 As shown. In the prior art, the guide rail base is a bent part, and the bent part 3 between the base plate 1 and the guide rail fixing plate 2 is rounded. This makes it so that when installing the guide rail 8, the bottom of the guide rail 8 cannot be attached to the base plate 1, and the back of the guide rail 8 cannot be attached to the guide rail fixing plate 2, resulting in poor installation effect.

[0003] To improve the installation effect, a shim plate 7 is welded onto the guide rail fixing plate 2. This way, when installing the guide rail 8, the guide rail 8 can avoid the bend 3, with its bottom attached to the base plate 1 and its back attached to the shim plate 7. If the shim plate 7 is not welded well, shims must be used to adjust the installation position during on-site installation. The disadvantage of this structure is that it requires welding the shim plate 7 and even using shims for adjustment, which increases the material and the manufacturing and installation process, resulting in poor economic efficiency.

[0004] In view of the aforementioned existing technology, it is necessary to make reasonable improvements to the structure of the existing guide rail base. To this end, the applicant has made beneficial designs, and the technical solution to be introduced below is a product of this background. Utility Model Content

[0005] The objective of this invention is to provide a guide rail base that eliminates the need for welding a raised plate, ensuring effective guide rail installation, saving materials, simplifying the structure and installation process, and improving installation efficiency.

[0006] The present invention accomplishes its objective as follows: a guide rail base is constructed by bending a flat plate, forming a base plate fixed to the ground, a guide rail fixing plate fixed to the guide rail, and a bent portion formed by bending between the base plate and the guide rail fixing plate. The key feature is that before bending, a concave slit with an open end is cut into the bent portion of the flat plate, with the open end of the concave slit facing the base plate. During bending, the guide rail fixing plate flips upwards, while the inner plate enclosed by the concave slit remains unfurled, thus forming a recessed countersunk hole in the bent portion. The guide rail is then embedded in the recessed countersunk hole during installation, and the two sides of the guide rail are blocked by the bent portion, thus providing installation guidance and positioning.

[0007] In a specific embodiment of this utility model, the concave gap is one of the following: arc shape, trapezoidal shape, and rectangle.

[0008] In another specific embodiment of this utility model, the two ends of the concave slit are located on the bent portion or extend to the bottom plate.

[0009] In another specific embodiment of this utility model, when the concave slit is rectangular, its bottom edge is parallel to the bent part, the distance between the two vertical sides of the concave slit perpendicular to the bottom edge is greater than the width W of the guide rail, and the vertical sides extend to the bottom plate.

[0010] This utility model, due to the above-mentioned structure, has the following beneficial effects: First, when installing the guide rail, the guide rail can effectively avoid the bending part, with the bottom attached to the base plate and the back attached to the guide rail fixing plate, ensuring the installation effect of the guide rail. At the same time, there is no need to weld the shim plate, and no need to use shims to adjust the installation position during on-site installation, saving materials, simplifying the structure and installation process, and greatly improving installation efficiency, which is suitable for the requirements of industrial scale-up production; Second, when installing the guide rail, the guide rail is embedded in the clearance countersunk hole, and the two sides are blocked by the bending part, which plays a role in installation guidance and positioning, thereby improving the positioning accuracy and installation convenience; Third, a flat plate of the corresponding size can be selected according to the size of the oil collection box and the guide rail, which has strong versatility and is suitable for guide rails and oil collection boxes of various specifications.

[0020] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. However, the description of the embodiments is not a limitation on the technical solution. Any formal but not substantive changes made based on the concept of this utility model should be considered within the protection scope of this utility model.

[0021] In the following description, all directional or orientational concepts involving up, down, left, right, front, and back are based on the positions shown in the corresponding figures, and therefore should not be construed as a special limitation on the technical solution provided by this utility model.

[0022] Please see Figure 3 , Figure 4 This utility model relates to a guide rail base, which is formed by bending a flat plate. It includes a base plate 1 fixedly installed to the ground, a guide rail fixing plate 2 fixedly installed to a guide rail 8, and a bent portion 3 formed by bending between the base plate 1 and the guide rail fixing plate 2. The bent portion 3 has rounded corners due to bending. Before bending, the bent portion 3 is straight and together with the base plate 1 and the guide rail fixing plate 2 constitutes the flat plate.

[0023] like Figure 6a , Figure 6b , Figure 6c As shown, before bending, a concave slit 4 with an open end and penetrating the flat plate is cut at the bending part 3. The open end of the concave slit 4 faces the bottom plate 1. The concave slit 4 can be arc-shaped, trapezoidal, rectangular, etc., and both ends of the concave slit 4 are located on the bending part 3 or extend to the bottom plate 1.

[0024] like Figure 4 , Figure 6a As shown, in this embodiment, the concave gap 4 is preferably rectangular. The bottom edge 41 of the concave gap 4 is parallel to the bending part 3. The distance between the two vertical edges 42 of the concave gap 4 that are perpendicular to the bottom edge 41 is greater than the width W of the guide rail 8, and the vertical edges 42 extend to the bottom plate 1.

[0025] like Figure 3 , Figure 4 , Figure 5As shown, during bending, the guide rail fixing plate 2 flips upward, while the inner extension plate 10 surrounded by the cut concave slit 4 is not flipped up and remains on the same flat plate as the base plate 1, resulting in a clearance countersunk hole 5 forming in the middle of the bending part 3. The guide rail 8 is embedded in the clearance countersunk hole 5 during installation, and its two sides are blocked by the bending part 3, thus playing a guiding and positioning role in installation, thereby improving the convenience of installation. At the same time, the bottom surface of the guide rail 8 is in contact with the base plate 1, and the back surface of the guide rail 8 is in contact with the guide rail fixing plate 2, eliminating the need for welding shims, saving on shim adjustments, simplifying the structure and installation process, and improving installation efficiency.

[0026] like Figure 3 As shown, an oil collection box 6 is installed on the base plate 1. Since the guide rail base is made of bent flat plate, the corresponding size of the flat plate can be selected according to the size of the oil collection box 6 and the guide rail 8, which has strong versatility.
