Attached Figure Description

[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0013] Figure 1 This is a schematic diagram of the connector structure of this utility model;

[0014] Figure 2 This is a schematic diagram of the installation structure of this utility model.

[0015] In the diagram, 1-crossbar fixing plate, 11-fixing hole, 2-side plate, 3-crossbar mounting protrusion, 4-tie rod connecting plate, 41-tensioning hole, 5-column, 6-crossbar, 7-tie rod. Detailed Implementation

[0016] 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, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0021] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0022] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0023] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0024] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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 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.

[0025] See Figure 1This utility model provides a technical solution: a special connector for splicing elevator shaft frame crossbars and tie rods, including a crossbar fixing plate 1, side plates 2 on both sides of the crossbar fixing plate 1, and multiple fixing holes 11 on the crossbar fixing plate 1. Two side plates 2 and the crossbar fixing plate 1 form a crossbar mounting protrusion 3. A tie rod connecting plate 4 is provided on the side of the two side plates 2 away from the crossbar fixing plate 1, and the tie rod connecting plate 4 is provided with a tensioning hole 41. This utility model allows the connector to be directly welded to the column 5 during production, reducing the components of the shaft frame to three parts: column 5, tie rod 7, and crossbar 6. Assembly is achieved through bolt and nut fastening, avoiding environmental pollution during assembly. It also requires no high-level skills to assemble the shaft frame, ensuring high construction safety and significantly shortening installation time, reducing the construction cycle, and lowering installation costs.

[0026] Preferably, the length of the tie rod connecting plate 4 is less than the length of the side plate 2, and the tie rod connecting plate 4 is flush with one side of the side plate 2. This ensures that each working plate can be connected to the column 5, improving the stability of the connection.

[0027] Preferably, the side plate 2 has a chamfer at the end furthest from the end flush with the tie rod connecting plate 4. The chamfer reduces raw material consumption and production costs without altering the overall structural strength, and also reduces the overall weight of the connector.

[0028] Preferably, there are three fixing holes 11 arranged in a triangle. Utilizing the stability of a triangle, the connection between the crossbar 6 and the crossbar fixing plate 1 is made more secure, increasing the overall stability of the derrick and giving it higher wind and earthquake resistance. During production, the length of the crossbar 6 should be slightly less than the distance between any two adjacent columns 5 to avoid excessive gaps between the crossbar 6 and the columns 5, which could cause loosening at the connection.

[0029] Preferably, the distribution triangle of the three fixing holes 11 is an equilateral triangle. Compared to irregular triangles, it has the characteristics of full symmetry and the convergence of the three lines, while also improving geometric stability. This further ensures the overall stability of the derrick.

[0030] Preferably, both the fixing hole 11 and the tensioning hole 41 are strip-shaped holes. This facilitates fixing and installation, improving the ease of installation.

[0031] Preferably, a connecting reinforcement plate is provided at one end of the crossbar fixing plate 1, side plate 2, and tie rod connecting plate 4 that are flush with each other. This makes the connection between the overall connector and the column 5 more secure and stable.

[0032] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Modifications and variations made by those skilled in the art that do not depart from the technology and scope of this utility model should be within the protection scope of the appended claims.
