Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and more specifically, to an adjustable elevator counterweight side support. Background Technology

[0002] Elevators are an indispensable piece of equipment in modern buildings. The installation and fixation of elevators are extremely important for their safe and stable operation. Currently, most vertical elevators have a straight guide rail structure installed on the side wall of the shaft. By installing a sliding structure on the side wall of the car that cooperates with the guide rail, the elevator car can be limited to move up and down in a straight line along the elevator shaft. This design usually uses elevator car brackets to support the guide rails on the shaft wall. However, due to the high speed and large impact force of elevators, there are high requirements for the strength and installation stability of the elevator car brackets.

[0003] Currently, most elevator guide rail bracket designs on the market use screws and welding to fix them to their corresponding positions. Their stability, safety, and connection strength largely depend on the design of the mounting holes on the elevator car side guide rail bracket. However, due to the long, straight structure of the elevator shaft itself, ensuring the straightness of the guide rails requires extremely strict installation techniques. Generally, guide rails are installed segment by segment using guide rail brackets and then connected to form a complete unit. Considering the workload, the installation of both the guide rail brackets and the guide rails requires a high degree of fixation at the assembly points. This means that once installed and fixed, it is difficult to make minor adjustments to the position. This results in the guide rails supported by the brackets having difficulty achieving high straightness, and it is almost impossible to make corrections in the later stages of installation.

[0004] In addition, the counterweight side support in the elevator guide rail bracket has a large extension length, so the stress at the connection point is also greater during elevator operation, making it prone to deformation and failure during use.

[0005] In summary, existing elevator counterweight side supports suffer from technical problems such as easy deformation and failure. Utility Model Content

[0006] The technical problem to be solved by this utility model is that the existing elevator counterweight side support is prone to deformation and failure.

[0007] To address the aforementioned problems, this utility model provides an adjustable elevator counterweight side support, comprising a counterweight fixing component and a guide rail mounting component that are installed and connected to each other. Both the counterweight fixing component and the guide rail connecting component are L-shaped right-angle bent plate structures. The counterweight fixing component includes a wall fixing plate and a first connecting plate that are perpendicular to each other and integrally formed. The wall fixing plate is used for fixed connection with the inner wall of the elevator shaft. The guide rail connecting component includes a guide rail mounting plate and a second connecting plate that are perpendicular to each other and integrally formed. The guide rail mounting plate is used for installation connection with the side guide rail of the elevator car. The first connecting plate and the second connecting plate are laterally connected by threaded connectors.

[0008] The width of the wall fixing plate is greater than the width of the first connecting plate. The end side of the first connecting plate adjacent to the wall fixing plate is provided with a widened extension, which is connected to the wall fixing plate with the same width. The side edges of the wall fixing plate, the first connecting plate and the widened extension are all provided with flanged reinforcing ribs perpendicular to the plate surface.

[0009] The adjustable elevator counterweight side support provided by this utility model mainly includes two parts: a counterweight fixing component and a guide rail mounting component. One part is fixed to the elevator shaft wall, and the other part is fixed to the elevator guide rail. The two are connected by a threaded connector. Due to the structural characteristics of the counterweight support, the first connecting plate has a large axial length. The wall fixing plate integrated with it needs to have a large width to resist torsion in order to ensure good stability of the support with large torque. Therefore, stress concentration is likely to occur at the connection position between the wall fixing plate and the first connecting plate, which is prone to breakage. Therefore, at the joint position between the first connecting plate and the wall fixing plate, the width of the side edge of the first connecting plate is widened to increase the width of the connection position. On this basis, vertical flanged reinforcing ribs are set on the side edge of the entire counterweight fixing component to further strengthen the structure and effectively solve the technical problem of easy deformation and failure of the existing elevator counterweight side support.

[0010] As a preferred embodiment, the symmetrical central axis region of the wall fixing plate is provided with a raised rib structure. The width of the raised rib structure gradually decreases from the first connecting plate towards the end of the wall fixing plate, forming a trapezoidal groove. This optimizes the wall fixing plate structure, enhancing its strength and anti-tipping performance.

[0011] As a preferred embodiment, the guide rail mounting plate is provided with two sets of guide rail hole groups. Each set of guide rail hole groups includes two guide rail mounting holes symmetrically distributed about the central axis of the guide rail mounting plate. The distance between the guide rail mounting holes in the two sets of guide rail hole groups and the central axis of the guide rail mounting plate is different, which is used to adapt to different guide rail and connector models. By optimizing the hole structure design of the above guide rail mounting plate, and setting two sets of guide rail hole groups with different hole spacings, it can adapt to elevator guide rails of different widths, and correspondingly, it can also adapt to different models of connectors.

[0012] As a preferred embodiment, the guide rail mounting holes are all oblong-shaped to provide adjustment allowance for the installation of the connectors. Optimizing the hole structure of the guide rail mounting holes, the oblong shape further increases the adjustment allowance for the installation position, reduces installation difficulty, and facilitates on-site operation.

[0013] As a preferred embodiment, both the guide rail mounting plate and the second connecting plate have raised rib structures in their respective symmetrical central axis regions. These raised rib structures are linear grooves that are interconnected. This enhances the strength of the guide rail mounting components and strengthens the impact resistance of the support.

[0014] As a preferred embodiment, both the first and second connecting plates are provided with elongated connecting holes. The axes of the elongated connecting holes on the first and second connecting plates are perpendicular to each other. The first and second connecting plates are installed and fixed by threaded connectors through their respective elongated connecting holes. Optimizing the docking structure design between the first and second connecting plates, and fixing them by assembling threaded connectors through symmetrically arranged elongated holes, provides adjustment margin and reduces assembly difficulty.

[0015] As a preferred embodiment, the central axis of the connecting elongated hole on the first connecting plate coincides with the symmetrical central axis of the first connecting plate, and the first connecting plate is provided with two or more coaxial connecting elongated holes. Based on the above structure, the distribution of the connecting holes on the first connecting plate is optimized.

[0016] As a preferred embodiment, a Y-shaped raised rib is provided in the middle region of the first connecting plate. The base of the Y-shaped raised rib is connected to the raised rib structure of the wall fixing plate. Two straight raised structures extend from the Y-shaped raised rib and are located on both sides of the connecting elongated hole. This optimizes the structure of the first connecting plate, enhancing its impact resistance through the Y-shaped raised rib, and adapting the Y-shaped structure to the connecting elongated hole to avoid interference.

[0017] As a preferred embodiment, the wall fixing plate has wall fixing holes on both sides of its raised rib structure. This optimizes the connection structure design between the wall fixing plate and the elevator shaft wall.

[0018] As a preferred embodiment, the wall fixing holes are elongated and slanted, and these elongated holes are symmetrically distributed along the raised rib structure. This optimization of the wall fixing hole structure, employing elongated and slanted holes, enhances the self-locking property of the connection and facilitates assembly. Attached Figure Description

[0028] refer to Figure 1 , Figure 2 The following examples illustrate this. Figure 1A schematic diagram of the structure of an adjustable elevator counterweight side support provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the counterweight side support of a centrally adjustable elevator from another angle.

[0029] This embodiment of the present invention provides an adjustable elevator counterweight side support, including a counterweight fixing component and a guide rail mounting component that are installed and connected to each other. Both the counterweight fixing component and the guide rail connecting component are L-shaped right-angle bent plate structures. The counterweight fixing component includes a wall fixing plate 1 and a first connecting plate 2 that are perpendicular to each other and integrally formed. The wall fixing plate 1 is used to fix and connect to the inner wall of the elevator shaft. The guide rail connecting component includes a guide rail mounting plate 4 and a second connecting plate 3 that are perpendicular to each other and integrally formed. The guide rail mounting plate 4 is used to install and connect to the side guide rail of the elevator car. The first connecting plate 2 and the second connecting plate 3 are connected laterally by threaded connectors. The width of the wall fixing plate 1 is greater than the width of the first connecting plate 2. The end side of the first connecting plate 2 adjacent to the wall fixing plate 1 is provided with a widened extension 10, which is connected to the wall fixing plate 1 with the same width. The side edges of the wall fixing plate 1, the first connecting plate 2, and the widened extension 10 are all provided with flanged reinforcing ribs 7 that are perpendicular to the plate surface.

[0030] The adjustable elevator counterweight side support provided in this embodiment mainly includes two parts: a counterweight fixing component and a guide rail mounting component. One part is fixed to the elevator shaft wall, and the other part is fixed to the elevator guide rail. The two are connected by a threaded connector. Due to the structural characteristics of the counterweight support, the first connecting plate has a large axial length. The wall fixing plate integrated with it needs to have a large width to resist torsion in order to ensure good stability of the support with large torque. Therefore, stress concentration is likely to occur at the connection position between the wall fixing plate and the first connecting plate, which is prone to breakage. Therefore, at the joint position between the first connecting plate and the wall fixing plate, the width of the side edge of the first connecting plate is widened to increase the width of the connection position. On this basis, vertical flanged reinforcing ribs are set on the side edge of the entire counterweight fixing component to further strengthen the structure and effectively solve the technical problem of easy deformation and failure of the existing elevator counterweight side support.

[0031] In the technical solution provided in this embodiment, a raised rib structure 5 is provided in the symmetrical central axis area of ​​the wall fixing plate 1. The width of the raised rib structure 5 gradually decreases from the first connecting plate 2 to the end of the wall fixing plate 1, and is in the shape of a trapezoidal groove.

[0032] This design optimizes the wall-mounted panel structure, enhancing its strength and anti-overturning performance. Specifically, a raised rib structure is set in the central axis area of ​​the panel structure. The raised rib structure adopts a trapezoidal groove structure with a larger radial width at one end and a smaller radial width at the other end. This asymmetrical reinforcing rib structure can greatly improve the anti-overturning characteristics of the wall-mounted panel and effectively enhance the stress resistance of the bracket.

[0033] In the technical solution provided in this embodiment, the guide rail mounting plate 4 is provided with two sets of guide rail holes. Each set of guide rail holes includes two guide rail mounting holes 9 symmetrically distributed about the central axis of the guide rail mounting plate 4. The distance between the guide rail mounting holes 9 of each of the two sets of guide rail holes and the central axis of the guide rail mounting plate 4 is different, which is used to adapt to different guide rail and connector models.

[0034] This design optimizes the hole structure design on the guide rail mounting plate. By setting two sets of guide rail hole groups with different hole spacing, it can adapt to elevator guide rails of different widths and can also adapt to different types of connectors.

[0035] In the technical solution provided in this embodiment, the guide rail mounting holes 9 are all oblong-shaped holes, used to provide installation and adjustment margins for the connectors. Optimizing the hole structure of the above-mentioned guide rail mounting holes, the oblong-shaped hole structure further increases the adjustment margin of the installation position, reduces installation difficulty, and facilitates on-site operation.

[0036] In the technical solution provided in this embodiment, both the guide rail mounting plate 4 and the second connecting plate 3 have raised rib structures 5 in their respective symmetrical central axis regions. These raised rib structures 5 are all linear grooves and are interconnected. This enhances the strength of the guide rail mounting components and strengthens the impact resistance of the support.

[0037] In the technical solution provided in this embodiment, both the first connecting plate 2 and the second connecting plate 3 are provided with connecting elongated holes 8. The axes of the connecting elongated holes 8 on the first connecting plate 2 and the connecting elongated holes 8 on the second connecting plate 3 are perpendicular to each other. The first connecting plate 2 and the second connecting plate 3 are installed and fixed by threaded connectors through their respective connecting elongated holes 8. The optimized docking structure design between the first connecting plate and the second connecting plate, and the installation and fixing of threaded connectors through symmetrically arranged elongated holes, provides adjustment margin and reduces assembly difficulty.

[0038] In the technical solution provided in this embodiment, the central axis of the connecting elongated hole 8 on the first connecting plate 2 coincides with the symmetrical central axis of the first connecting plate 2, and the first connecting plate 2 is provided with two or more coaxial connecting elongated holes 8. Based on the above structure, the distribution of connecting holes on the first connecting plate is optimized.

[0039] refer to Figure 3 and Figure 4 The following examples illustrate this. Figure 3A schematic diagram of another adjustable elevator counterweight side support provided by this utility model; Figure 4 for Figure 3 A schematic diagram of the counterweight side support of a centrally adjustable elevator from another angle.

[0040] In the technical solution provided in this embodiment, a Y-shaped protruding rib 11 is provided in the middle region of the first connecting plate 2. The base of the Y-shaped protruding rib 11 is connected to the protruding rib structure 5 of the wall fixing plate 1. The Y-shaped protruding rib 11 extends out two straight protruding structures located on both sides of the connecting elongated hole 8.

[0041] The design optimizes the structure of the first connecting plate by using Y-shaped raised ribs to enhance the impact resistance of the plate and adapt to the long hole of the connection through the Y-shaped structure to avoid interference. The wider end of the Y-shaped raised rib is connected to the raised rib structure of the wall fastener, while the two raised ribs at the other end are parallel to each other in a straight line to connect the two sides of the long hole. This not only avoids interference with the hole but also greatly improves the strength of the hole.

[0042] In the technical solution provided in this embodiment, the wall fixing plate 1 has wall fixing holes 6 on both sides of its raised rib structure 5. The connection structure design between the wall fixing plate 1 and the elevator shaft wall is optimized.

[0043] In the technical solution provided in this embodiment, the wall fixing holes 6 are obliquely elongated holes, which are symmetrically distributed along the raised pressure rib structure 5. The structural design of the wall fixing holes is optimized. The use of obliquely elongated holes enhances the self-locking property of the connection and facilitates assembly.

[0044] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
