Description

Technical Field

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

[0002] Elevators are indispensable equipment in modern buildings. The proper installation and securing of elevators are crucial for their safe and stable operation. Most elevators are equipped with counterweights, which are typically installed on the side or rear. Side-mounted counterweights are commonly found in machine-room-less passenger elevators, sightseeing elevators, freight elevators, and medical elevators. The counterweight requires corresponding side supports to create structural constraints between it and the elevator shaft wall. Due to the high speed and impact of elevators, significant vibrations occur during operation. The counterweight side experiences the same vibrations, leading to friction between the guide rail supports and the shaft wall or guide rails. This poses a risk of structural damage to the guide rail supports, reduces their lifespan, and in severe cases, compromises the elevator's operational safety. Furthermore, the vibrations during elevator operation generate considerable noise, significantly impacting the user experience.

[0003] In summary, existing elevator counterweight side supports have technical problems such as the support connection and fit being easily affected by the elevator's operating mode, resulting in a high risk of structural damage and noise generation. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the existing elevator counterweight side support has a high risk of structural damage and noise due to the support connection and cooperation being easily affected by the elevator's operating mode.

[0005] To address the aforementioned problems, this utility model provides an elevator counterweight vibration damping side support device, including a guide rail support fixedly installed to the elevator side guide rail and a counterweight mounting component fixedly connected to the elevator shaft wall. It also includes a damping mechanism connected to the guide rail support or the counterweight mounting component. The guide rail support is installed and connected to the counterweight mounting component. The counterweight mounting component includes an integrally formed damping mounting plate, a connecting plate, and a counterweight base plate arranged parallel to the damping mounting plate. The surfaces of the damping mounting plate and the connecting plate are perpendicular to each other and at the same height. The damping mechanism is disposed between the damping mounting plate and the counterweight base plate. The top edge of the connecting plate abuts against the bottom plate of the guide rail support. The damping mechanism includes an elastic block and a pressure plate pressed and fixed to the pressure-bearing side of the elastic block. The pressure plate is parallel to the damping mounting plate, and the pressure plate presses the elastic block tightly against the damping mounting plate and the counterweight base plate, forming an elastic connection between them.

[0006] This utility model provides a novel counterweight support design, adding a shock-absorbing design to the traditional support structure. To accommodate the shock-absorbing structure, the counterweight mounting component adopts a right-angle integral structure. To ensure the support can provide good support to the counterweight side guide rail, the guide rail support component is connected to the side edge of the right-angle counterweight mounting component, which can better utilize the inherent strength of the right-angle structure. One end of the counterweight mounting component is fixed to the elevator shaft wall through the counterweight base plate, while the shock-absorbing mechanism is connected between the counterweight base plate and the counterweight mounting component. The fixing method between the counterweight mounting component and the counterweight base plate is surface-fitting fixation. To adapt to this structure, the shock-absorbing mechanism adopts a plate-surface pressing functional structure. The main functional component is an elastic pressure block, which is attached between the counterweight base plate and the shock-absorbing mounting plate and presses against the plate. The plate provides clamping force to ensure the accurate positioning of the elastic pressure block. This shock absorption mechanism design can form an elastic connection between the counterweight side guide rail bracket, which bears the impact of elevator operation, and the fixed elevator shaft wall, replacing the completely rigid docking of the existing design. The vibration is completely transferred from the bracket itself to the elastic pressure block. The elastic pressure block, which is pressed by the connection position, provides elastic damping. The vibration transmitted by the elevator operation to the counterweight side bracket is weakened by the shock absorption mechanism, avoiding the connection failure and damage caused by the loosening of the bracket connection position due to continuous vibration. It can also greatly reduce the noise of elevator movement. It effectively solves the technical problems of the existing elevator counterweight side bracket where the bracket connection is easily affected by the elevator operation mode, resulting in a high risk of structural damage and noise generation.

[0007] As a preferred embodiment, the shock absorption mechanism includes two parallel and aligned first elastic blocks, a second elastic block, a first pressure plate, and a second pressure plate. The second pressure plate, the second elastic block, the shock absorption mounting plate, the first elastic block, the first pressure plate, and the counterweight base plate are stacked sequentially and pressed together by the pressing mechanism.

[0008] Based on the aforementioned structure, this design further optimizes the vibration damping design by employing multiple elastic pressure blocks to provide shock absorption. The two damping pressure blocks are parallel and aligned, with one sandwiched between the damping mounting plate and the counterweight base plate, and the other positioned on the other side of the damping mounting plate. In other words, the damping mounting plate is sandwiched between the two damping pressure blocks. The positioning pressure block also adopts a two-plate structure, allowing the damping mounting plate to have a margin for slight displacement in both forward and backward directions. This further enhances the vibration damping effect and reduces noise generated by collisions at the connection points.

[0009] As a preferred embodiment, the second pressure plate, the second elastic pressure block, the shock-absorbing mounting plate, the first elastic pressure block, the first pressure plate, and the counterweight base plate each have multiple positioning through holes evenly distributed on their respective surfaces. These positioning through holes communicate with corresponding positioning through holes on adjacent components. The clamping mechanism is an anchoring rod, which passes through each of the corresponding positioning through holes and is anchored at both ends to the second pressure plate and the counterweight base plate, respectively. This design provides a cooperative connection structure between the shock-absorbing mechanism and the support. Anchoring rods are used to connect the functional components within the shock-absorbing mechanism, namely the elastic pressure block and the pressure plate, as well as the plates connecting the shock-absorbing mechanism. The anchoring rods connect the workpieces into a single structural unit and provide clamping force on the elastic pressure block, ensuring the effective elastic connection. The preferred design uses multiple anchoring rods evenly distributed across the surface of the workpiece to be fixed, ensuring a firm connection and uniform force distribution.

[0010] As a preferred embodiment, the first and second elastic pressure blocks are rigid rubber parts with the same shape, and the first and second pressure plates are both rigid plates with an outer contour shape consistent with the first elastic pressure block. This design optimizes the selection of structural materials for the shock absorption mechanism. The elastic pressure blocks are all made of rigid rubber parts, which are plates directly molded from the material. Using rigid rubber as the molding material has the beneficial effects of moderate elasticity and durability. Due to the elasticity of the pressure blocks, in order to ensure good positioning of the pressure blocks, rigid plates are used to compress the two sides of the material to achieve positioning.

[0011] As a preferred embodiment, the surface area of ​​the counterweight base plate is larger than that of the first pressure plate. The counterweight base plate has a plurality of mounting elongated holes for fixing to the elevator shaft wall in the area of ​​its surface that extends beyond the outline of the first pressure plate. The end of the anchoring rod that is anchored to the counterweight base plate is planar, and the height of the end plane does not exceed the surface of the counterweight base plate.

[0012] To adapt to the overall design of the aforementioned shock absorption mechanism, the connection structure between the bracket and the elevator shaft wall is optimized. The counterweight plate is used to fix the bracket to the elevator shaft wall, while the other side of the plate connects with the shock absorption mechanism. To ensure a simple structure and easy installation, and because the installation of the bracket and the elevator shaft wall should ideally have a certain degree of flexibility, the counterweight plate is fixed to the shaft wall using elongated holes, allowing for fine-tuning of the installation position. Furthermore, to prevent the anchor rods used to connect the shock absorption mechanism from protruding on the other side of the counterweight plate, which would make it difficult for the counterweight plate to fit against the shaft wall plane, the ends of the anchor rods are made flat and do not protrude from the surface of the counterweight plate.

[0013] As a preferred embodiment, both the upper and lower sides of the shock-absorbing mounting plate and the connecting plate are integrally connected with flanges perpendicular to their respective surfaces, and the flanges on the corresponding sides of the shock-absorbing mounting plate and the connecting plate are interconnected as a whole; the flange of the connecting plate is provided with a lower connecting elongated hole along the length of the plate, and the lower connecting elongated hole is used for installation and fixation with the base plate of the guide rail support.

[0014] This design further enhances the structural strength of the support itself. Flanged structures are set on the upper and lower sides of the right-angled counterweight mounting component along the length of the workpiece. The flanged plates are integrally and vertically connected to the workpiece plate surface, which greatly enhances the tensile, compressive and torsional resistance of the support. Furthermore, the holes for connecting with the guide rail support are set on the flanged plates, which can improve the strength of the connection position and make the connection position or hole position less prone to damage.

[0015] As a preferred embodiment, the base plate of the guide rail support is provided with an upper elongated hole, the position of which corresponds to the position of the lower elongated hole. The length directions of the upper and lower elongated holes are perpendicular to each other. By aligning the upper and lower elongated holes and inserting rods, the guide rail support is adjusted to engage with the connecting plate. This design optimizes the fit between the guide rail support and the connecting plate. Upper and lower elongated holes are designed at corresponding positions on both, with their axial directions parallel and aligned, and their length directions on their respective plates perpendicular to each other. This allows the guide rail support to be adjusted to engage with the connecting plate when fastening rods are inserted into the corresponding holes.

[0016] As a preferred embodiment, the connecting plate has a cover plate at its end furthest from the shock absorption mechanism. The cover plate is perpendicular to and integrally formed with the surface of the connecting plate, and both sides of the cover plate are integrally connected to the flanged ends of the connecting plate. This design further optimizes the structural strength of the support, as the cover plate at the end of the connecting plate and its upper and lower flanges can be connected to form a stable, integrated structure.

[0017] As a preferred embodiment, the cover plate has a notch structure on its side edge opposite to the connecting plate, which is used for wiring at the corresponding position of the elevator. This design further optimizes the performance of the bracket based on the above structure, allowing for convenient wiring within the space formed by the flip plate and the flip plates on both sides.

[0018] As a preferred embodiment, the damping mounting plate also has a cover plate at its end furthest from the connecting plate. The cover plate is perpendicular to the surface of the damping mounting plate and integrally formed. Both sides of the cover plate are integrally connected to the flanged ends of the damping mounting plate on both sides. This design is a further optimization of the technical concept of the above-mentioned solution. Similar to the connecting plate structure, a cover plate is also provided at the end of the damping mounting plate, which also effectively improves the structural strength.

[0023] refer to Figures 1-4 The following examples illustrate this. Figure 1 A schematic diagram of the overall structure of an elevator counterweight damping side support device provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the other side of the counterweight damping support device for the elevator.

[0024] The elevator counterweight vibration damping side support device provided in this embodiment includes a guide rail support 1 fixedly installed to the elevator side guide rail and a counterweight mounting component 2 fixedly connected to the elevator shaft wall. It also includes a damping mechanism 3 connected to the guide rail support 1 or the counterweight mounting component 2. The guide rail support 1 is installed and connected to the counterweight mounting component 2. The counterweight mounting component 2 includes an integrally formed vibration damping mounting plate 2-2, a connecting plate 2-1, and a counterweight base plate 2-3 arranged parallel to the vibration damping mounting plate 2-2. The vibration damping mounting plate 2-2... The connecting plate 2-1 is perpendicular to each other and at the same height. The damping mechanism 3 is located between the damping mounting plate 2-2 and the counterweight base plate 2-3. The top side edge of the connecting plate 2-1 is abutted and connected to the bottom plate 1-1 of the guide rail support 1. The damping mechanism 3 includes an elastic block and a pressure plate that is pressed and fixed to the pressure side of the elastic block. The pressure plate is parallel to the damping mounting plate 2-2. The pressure plate presses the elastic block tightly against the damping mounting plate 2-2 and the counterweight base plate 2-3, forming an elastic connection between them.

[0025] This utility model provides a novel counterweight support design, which adds a shock-absorbing design to the traditional support structure. To adapt to the shock-absorbing structure, the counterweight mounting component 2 adopts a right-angle integral structure. To ensure that the support can provide good support to the counterweight side guide rail, the guide rail support component 1 is connected to the side edge of the right-angle counterweight mounting component 2, which can better utilize the inherent strength of the right-angle structure. One end of the counterweight mounting component 2 is fixed to the elevator shaft wall through the counterweight base plate 2-3, and the shock-absorbing mechanism 3 is connected between the counterweight base plate 2-3 and the counterweight mounting component 2. The counterweight mounting component 2 and the counterweight base plate 2-3 are fixed by surface contact. To adapt to this structure, the shock-absorbing mechanism 3 adopts a plate-surface pressing functional structure. The main functional component is an elastic pressure block, which is attached to the counterweight base plate 2-3 and the shock-absorbing mounting component 2. Between plates 2-2, and with the pressure plate providing clamping force to ensure the accurate positioning of the elastic pressure block, this shock absorption mechanism 3 design can form an elastic connection between the counterweight side guide rail bracket that bears the impact of elevator operation and the fixed elevator shaft wall, replacing the completely rigid docking of the existing design. The vibration is completely transformed from being elastically borne by the bracket itself to being borne by the elastic pressure block. Through the elastic pressure block pressed by the connection position, elastic damping is provided, and the vibration transmitted by the elevator operation to the counterweight side bracket is weakened by the shock absorption mechanism 3. This avoids the connection position of the bracket that may be loosened due to continuous vibration, causing connection failure and damage. It can also greatly reduce the noise of elevator movement, effectively solving the technical problems of the existing elevator counterweight side bracket where the bracket connection is easily affected by the elevator operation mode, resulting in a high risk of structural damage and noise generation.

[0026] In the technical solution provided in this embodiment, the shock absorption mechanism 3 includes two parallel and aligned first elastic pressure blocks 3-3 and second elastic pressure blocks 3-2, as well as a first pressure plate 3-4 and a second pressure plate 3-1. The second pressure plate 3-1, the second elastic pressure block 3-2, the shock absorption mounting plate 2-2, the first elastic pressure block 3-3, the first pressure plate 3-4, and the counterweight base plate 2-3 are stacked sequentially and pressed together by the pressing mechanism.

[0027] Based on the above structure, this design further optimizes the vibration damping design by using multiple elastic pressure blocks to provide shock absorption. The two damping pressure blocks are parallel and aligned, with one sandwiched between the damping mounting plate 2-2 and the counterweight base plate 2-3, and the other set on the other side of the damping mounting plate 2-2. That is, the damping mounting plate 2-2 is sandwiched between the two damping pressure blocks. The pressure block used for positioning also adopts a two-plate structure, allowing the damping mounting plate 2-2 to have a small displacement margin in both forward and backward directions, thereby further improving the vibration damping effect and reducing the noise generated by collisions at the connection points.

[0028] In the technical solution provided in this embodiment, the second pressure plate 3-1, the second elastic pressure block 3-2, the shock-absorbing mounting plate 2-2, the first elastic pressure block 3-3, the first pressure plate 3-4, and the counterweight base plate 2-3 each have multiple positioning through holes evenly distributed on their respective surfaces. The positioning through holes are all connected to the corresponding positioning through holes on the adjacent components. The clamping mechanism is an anchor rod 3-5, which passes through each positioning through hole at the corresponding position and is anchored at both ends to the second pressure plate 3-1 and the counterweight base plate 2-3, respectively. This design provides a connection structure between the shock-absorbing mechanism 3 and the support. The various functional components of the shock-absorbing mechanism 3, namely the elastic pressure block and the pressure plate, as well as the plates connecting the shock-absorbing mechanism 3, are passed through anchor rods 3-5. The anchor rods 3-5 connect the various workpieces into a whole structure and provide clamping force on the elastic pressure block to ensure the effective function of the elastic connection. The preferred design is to evenly distribute multiple anchor rods 3-5 on the surface of the workpiece to be fixed to ensure a firm connection and uniform force distribution.

[0029] In the technical solution provided in this embodiment, the first elastic pressure block 3-3 and the second elastic pressure block 3-2 are hard rubber parts with the same shape, and the first pressure plate 3-4 and the second pressure plate 3-1 are both rigid plates with the same outer contour shape as the first elastic pressure block 3-3. This design optimizes the selection of structural materials for the shock absorption mechanism 3. The elastic pressure blocks are all made of hard rubber parts, which are plates directly molded from the material. Using hard rubber as the molding material has the beneficial effects of moderate elasticity and durability. Due to the elasticity of the elastic pressure blocks, in order to ensure good positioning of the pressure blocks, rigid plates are used to squeeze the two sides of the material to achieve positioning.

[0030] In the technical solution provided in this embodiment, the surface area of ​​the counterweight base plate 2-3 is larger than that of the first pressure plate 3-4. The counterweight base plate 2-3 has a plurality of mounting elongated holes 2-4 for fixing to the elevator shaft wall in the area where its surface extends beyond the outline of the first pressure plate 3-4. The end of the anchoring rod 3-5 anchored to the counterweight base plate 2-3 is planar, and the height of the end plane does not exceed the surface of the counterweight base plate 2-3.

[0031] To adapt to the overall design of the above-mentioned shock absorption mechanism 3, the connection structure between the bracket and the elevator shaft wall is optimized. The counterweight plate 2-3 is used to fix the bracket to the elevator shaft wall, while the other side of the plate is connected to the shock absorption mechanism 3. In order to ensure simple structure and easy installation, and since the installation of the bracket and the elevator shaft wall should have a certain degree of flexibility, the counterweight plate 2-3 is fixed to the shaft wall in the form of elongated holes, so that the installation position can be finely adjusted. In addition, to avoid the anchor rod 3-5 used to connect the shock absorption mechanism 3 from protruding on the other side surface of the counterweight plate 2-3, which would make it difficult for the counterweight plate 2-3 to fit against the shaft wall plane, the end of the anchor rod 3-5 is made flat and does not protrude from the surface of the counterweight plate 2-3.

[0032] In the technical solution provided in this embodiment, both the upper and lower sides of the shock-absorbing mounting plate 2-2 and the connecting plate 2-1 are integrally connected with flange plates 4 perpendicular to their respective plate surfaces. The flange plates 4 on the corresponding sides of the shock-absorbing mounting plate 2-2 and the connecting plate 2-1 are connected to each other as a whole. The flange plate 4 of the connecting plate 2-1 is provided with a lower connecting elongated hole 4-1 along the length direction of the plate. The lower connecting elongated hole 4-1 is used for installation and fixation with the base plate 1-1 of the guide rail support 1.

[0033] This design further enhances the structural strength of the support itself. Flanged structures are set on the upper and lower sides of the right-angled counterweight mounting part 2 along the length of the workpiece. The flanged plate 4 is integrally and vertically connected to the workpiece plate surface, which greatly enhances the tensile, compressive and torsional resistance of the support. Furthermore, the hole for connecting with the guide rail support part 1 is set on the flanged plate 4, which can improve the strength of the connection position and make the connection position or hole position less prone to damage.

[0034] In the technical solution provided in this embodiment, the base plate 1-1 of the guide rail support 1 is provided with an upper connecting elongated hole 1-2, the position of which corresponds to the position of the lower connecting elongated hole 4-1. The length directions of the upper connecting elongated hole 1-2 and the lower connecting elongated hole 4-1 are perpendicular to each other. By aligning the upper connecting elongated hole 1-2 and the lower connecting elongated hole 4-1 and inserting rods, the guide rail support 1 and the connecting plate 2-1 are adjusted to be connected. This design optimizes the fit design between the guide rail support 1 and the connecting plate 2-1. The upper connecting elongated hole 1-2 and the lower connecting elongated hole 4-1 are designed at corresponding positions on both, and the hole axis directions of the upper connecting elongated hole 1-2 and the lower connecting elongated hole 4-1 are parallel and aligned. Moreover, the length directions of the two holes on their respective plates are perpendicular to each other. Thus, when fastening rods are inserted into the two holes at corresponding positions, the guide rail support 1 and the connecting plate 2-1 can be adjusted to be connected.

[0035] In the technical solution provided in this embodiment, a cover plate 5 is provided at the end of the connecting plate 2-1 away from the shock absorption mechanism 3. The cover plate 5 is perpendicular to the plate surface of the connecting plate 2-1 and integrally connected. The two sides of the cover plate 5 are integrally connected to the ends of the flange plates 4 on both sides of the connecting plate 2-1. This design further optimizes the structural strength of the support. The cover plate 5 is provided at the end of the plate surface of the connecting plate 2-1, and the cover plate 5 and its upper and lower flanges can be connected to form an integral and stable structure.

[0036] In the technical solution provided in this embodiment, the cover plate 5 has a notch structure on its side edge facing away from the connecting plate 2-1. The notch structure is used for wiring at the corresponding position of the elevator. This design further optimizes the performance of the bracket based on the above structure, allowing for convenient wiring within the space formed by the flip plate and the two side flap plates 4.

[0037] In the technical solution provided in this embodiment, a cover plate 5 is also provided at the end of the damping mounting plate 2-2 away from the connecting plate 2-1. The cover plate 5 is perpendicular to the plate surface of the damping mounting plate 2-2 and integrally connected. The two sides of the cover plate 5 are integrally connected to the ends of the flange plates 4 on both sides of the damping mounting plate 2-2. This design is a further optimization of the technical concept of the above-mentioned technical solution. Similar to the structure of the connecting plate 2-1, a cover plate 5 is also provided at the end of the damping mounting plate 2-2, which also has the effect of improving the structural strength.

[0038] Although the embodiments of this utility model have been disclosed above, the scope of protection of this utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this application, and all such changes and modifications will fall within the protection scope of this utility model.
