Description

Technical Field

[0001] This utility model belongs to the field of elevator guide rail installation technology, and in particular relates to an elevator guide rail connecting plate. Background Technology

[0002] During elevator assembly, guide rails are typically installed to ensure smooth and normal operation. Since each guide rail has a fixed length, they need to be connected by connecting plates to reach the specified height.

[0003] Current guide rail connecting plates are typically made of a single steel plate, which acts as a backing plate tightly against the ends of the two guide rails to be connected. By tightening eight standard bolts, the guide rails can be continuously extended or raised. This type of steel plate is made from hot-rolled flat steel, and to ensure its connection strength, the plate is relatively thick, resulting in higher material costs. Furthermore, during installation and maintenance, the heavy steel plate increases the operational burden, especially in confined spaces such as elevator shafts, which can affect the ease of installation and maintenance.

[0004] Therefore, it is necessary to improve the elevator guide rail connecting plate in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide an elevator guide rail connecting plate, which reduces the production cost of the connecting plate.

[0006] To achieve the above objectives, the specific technical solution of the elevator guide rail connecting plate of this utility model is as follows:

[0007] An elevator guide rail connecting plate includes a connecting plate body for connecting the ends of two guide rails. The guide rails and the connecting plate body are connected to each other by a bolt assembly. The connecting plate body has a corrugated structure, and the extension direction along the corrugation peaks of the connecting plate body is a first direction, which is consistent with the extension direction of the guide rails.

[0008] Preferably, in order to improve the structural strength at the second spiral hole, the main body of the connecting plate is provided with a second bolt hole, and an annular hole reinforcement is provided around the periphery of the second bolt hole.

[0009] Preferably, in order to improve the tensile strength of the connecting plate body along the direction perpendicular to the first direction, a reinforcing strip is provided on the connecting plate body, and the extension direction of the reinforcing strip is perpendicular to the first direction.

[0010] Preferably, in order to improve the overall strength of the connecting plate body, the reinforcing strip is connected to the hole reinforcing part.

[0011] Preferably, in order to reduce the noise during elevator operation, a damping pad is provided between the main body of the connecting plate and the guide rail.

[0012] Preferably, in order to improve the stability of the connection between the main body of the connecting plate and the guide rail, the cross-section of the main body of the connecting plate is a trapezoidal wave structure.

[0013] Preferably, in order to further reduce the noise during elevator operation, the interior of the ribbed body of the connecting plate is filled with sound-absorbing materials.

[0014] Preferably, in order to further improve the stability of the connection between the connecting plate body and the guide rail, the side of the connecting plate body adjacent to the guide rail is the contact surface, and the side of the reinforcing strip adjacent to the guide rail coincides with the contact surface.

[0015] Preferably, in order to improve the ease of positioning between the connecting plate body and the guide rail, the guide rail is provided with a first bolt hole, and a recess is provided at one end of the first bolt hole near the connecting plate body. The hole reinforcement is provided at one end of the guide rail protruding from the mating surface and matching the recess.

[0016] The elevator guide rail connecting plate of this utility model has the following advantages: the main body of the connecting plate is set as a corrugated structure. The corrugated structure can disperse the stress path, so that the main body of the connecting plate can achieve the same structural strength as a thick steel plate with a thinner thickness. Thus, while ensuring the strength of the main body of the connecting plate, the weight of the main body of the connecting plate is reduced, thereby reducing production costs and improving the convenience of elevator installation and maintenance.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0025] The terms "top surface," "bottom surface," and "full surface" refer to the normal operating state of the elevator guide rail connecting plate and are used only for the purpose of describing this utility model and simplifying the description. They are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model.

[0026] like Figure 1 and 3 As shown, an elevator guide rail connecting plate includes a connecting plate body 2 for connecting the ends of two guide rails 1. The guide rails 1 and the connecting plate body 2 are connected to each other by bolt assembly 3. The connecting plate body 2 has a corrugated structure, and the extension direction along the corrugation peak of the connecting plate body 2 is a first direction, which is consistent with the extension direction of the guide rails 1.

[0027] The aforementioned connecting plate is suitable for connection and reinforcement when the ends of elevator guide rails are joined. The corrugated connecting plate body 2 forms a three-dimensional load-bearing structure. By optimizing stress distribution and improving structural rigidity and toughness, the connecting plate body 2 achieves structural strength comparable to thick steel plates with a thinner thickness. While ensuring the structural strength of the connecting plate body 2, the thickness of the connecting plate body 2 can be reduced, thereby reducing the weight of the connecting plate body 2, reducing the amount of material used in the production of the connecting plate, and lowering production costs. Furthermore, the lighter connecting plate makes it easier for installers to maintain and install elevators, improving the convenience of elevator installation and maintenance. In addition, the connecting plate body 2 is not bent along the direction of the corrugation peaks, so there is no excess stretching. The corrugation peaks are arranged in the same direction as the extension direction of the guide rail 1, so that the connecting plate body 2 can effectively restrict the movement of the guide rail 1 along its own extension direction, thereby improving the stability of the connection and positioning between the two guide rails 1.

[0028] Further improvements include, for example Figure 5As shown, the connecting plate body 2 has a second bolt hole 201, and an annular hole reinforcement 203 is provided around the periphery of the second bolt hole 201. In the above-mentioned connecting plate, the connecting plate body 2 has eight second bolt holes 201, which are used to pass through the bolts of the bolt assembly 3, thereby fixing the connecting plate body 2 to the two guide rails 1 together through the bolts and nuts of the bolt assembly 3, realizing the connection and fixation between the two guide rails 1. Among the eight second bolt holes 201, four are grouped together for fixed connection with one of the guide rails 1; the hole reinforcement 203 is integrally stamped with the connecting plate body 2, and the hole reinforcement 203 can be provided by increasing the thickness of the material around the second bolt hole 201. The degree and continuity of the connection will transmit and disperse the concentrated stress over a wider range, reduce the stress peak at the edge of the second bolt hole 201, and avoid structural damage caused by excessive local stress. This will improve the reliability of the connection between the second bolt hole 201 and the bolt assembly, and enhance the firmness of the connection between the connecting plate and the elevator guide rail. Furthermore, the hole reinforcement 203 can provide reliable support for the bolt assembly 3 along the thickness direction of the connecting plate body 2, thereby improving the firmness of the bolt assembly 3 installation and preventing the bolt assembly 3 from directly exerting force on the corrugated structure, which would cause the corrugated structure to be squeezed and deformed along the thickness direction.

[0029] Further improvements include, for example Figure 5 As shown, a reinforcing strip 202 is provided on the main body 2 of the connecting plate, and the extending direction of the reinforcing strip 202 is perpendicular to the first direction. In this connecting plate, the reinforcing strip 202 is integrally stamped and formed on the main body 2 of the connecting plate. The setting of the reinforcing strip 202 can improve the rigidity of the main body 2 of the connecting plate along the direction perpendicular to the first direction, so as to resist the bending deformation of the main body 2 of the connecting plate along this direction, and significantly improve the overall strength of the main body 2 of the connecting plate.

[0030] Further improvements include, for example Figure 5 As shown, the reinforcing strip 202 and the hole reinforcing part 203 are interconnected. After the two are interconnected, they form an integral structure, which can expand the stress dispersion range caused by the pre-tightening force at the second bolt hole 201, further strengthen the structure at the second bolt hole 201, improve the stability of the overall structure of the connecting plate, and thus improve the stability of the connecting plate connecting to the guide rail.

[0031] Further improvements include, for example Figure 2 As shown, a damping pad 4 is provided between the connecting plate body 2 and the guide rail 1. The damping pad 4 is a butyl rubber pad, which can effectively absorb the vibration energy of the guide rail 1 and the connecting plate body 2, thereby reducing noise generation and improving the quietness and comfort of elevator operation.

[0032] Further improvements include, for example Figure 5As shown, the cross-section of the connecting plate body 2 is a trapezoidal wave structure. In this connecting plate, the trapezoidal wave structure makes the peaks of the connecting plate body 2 form a plane, which can increase the contact area between the connecting plate body 2 and the guide rail 1. The larger contact area can better distribute the load and avoid stress concentration; it can also more stably limit the relative displacement between the two and improve the overall strength of the structure after the two are connected.

[0033] Further improvements include, for example Figure 2 As shown, the interior of the ribbed core 2 of the connecting plate is filled with sound-absorbing components 5. Specifically, the sound-absorbing component 5 is a polyurethane foam board. Through the porous structure of the sound-absorbing component 5, the noise generated between the guide rail 1 and the connecting plate core 2 can be absorbed, further improving the quietness of elevator operation and enhancing passenger comfort.

[0034] Further improvements include, for example Figure 6 As shown, the side of the connecting plate body 2 adjacent to the guide rail 1 is the contact surface 204, and the side of the reinforcing strip 202 adjacent to the guide rail 1 coincides with the contact surface 204. The thickness of the reinforcing strip 202 is the same as that of the connecting plate body 2, so that the two sides of the reinforcing strip 202 are flush with the two sides of the connecting plate body 2, thus maintaining the uniformity of the thickness of the connecting plate body 2. The reinforcing strip 202 can further increase the contact area between the contact surface 204 and the guide rail 1, improving the stability of the connection between the two.

[0035] Further improvements include, for example Figure 4 and 6 As shown, the guide rail 1 has a first bolt hole 101. A recess 102 is provided at one end of the first bolt hole 101 near the connecting plate body 2. A hole reinforcement 203 protrudes from the mating surface 204 at one end near the guide rail 1 and matches the recess 102. Four first bolt holes 101 are provided on the guide rail 1, their positions corresponding to the second connecting holes 201 on the connecting plate body 2, allowing the bolt assembly 3 to pass through the first bolt holes 101 and the second bolt holes 201 to reinforce the connection between the guide rail 1 and the connecting plate body 2. The recess 102 and the hole reinforcement 203 interlock, providing mutual positioning between the guide rail 1 and the connecting plate body 2, thus improving the strength of the connection. During installation, the recess 102 and the hole reinforcement 203 mutually limit each other, pre-positioning the guide rail 1 and the connecting plate body 2, thereby improving the accuracy of the connection between the connecting plate and the guide rail 1 and the ease of installation.
