Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an integrated structure of elevator door operator and lintel, as well as an elevator. Background Technology

[0002] Currently, there are three main installation methods for elevator door operators on the market: one is to install them directly on the reinforcing ribs of the car door lintel; the second is to install them on the front support of the car frame; and the third is to install them on the car top via brackets. The door operator and the door lintel are independent structures, and an appropriate installation gap must be ensured between them when arranging the door operator.

[0003] Installing the gantry crane on the front pillar or car roof typically requires a long support frame, increasing costs. While installing the gantry crane directly on the lintel reinforcement eliminates the need for a support frame, it still presents significant drawbacks: First, the resulting long cantilever structure leads to poor installation stability; second, if the lintel is made of stainless steel, the reliability of the connection between the reinforcement and the lintel is questionable—adhesive bonding is insufficiently secure, while welding may damage the decorative finish.

[0004] Furthermore, most gantry crane motors are currently installed outside the elevator car. During installation or maintenance, operators must either stand on top of the car or move the crane to a level position before operating it from outside the hall. This process typically requires two people working together to stop the elevator and slow it down, making it complex and inefficient. Utility Model Content

[0005] Based on this, this utility model proposes a compact, easy-to-maintain integrated structure of elevator door operator and lintel, as well as an elevator.

[0006] Firstly, the technical solution provided by this utility model includes: An integrated structure of elevator door operator and door lintel includes a door operator assembly installed above the entrance and exit of the car body; the door operator assembly includes a door operator base plate, on which a door motor and a transmission mechanism for drivingly connecting the door motor and the door mounting plate are provided; The bottom of the door operator base plate is connected to the front wall of the car body, and the top of the door operator base plate is connected to the car roof of the car body; The door operator assembly has a removable lintel decorative panel on its inner side.

[0007] As a further optional solution, the door operator base plate includes a vertically arranged main body, with a top plate and a bottom plate extending from the upper and lower edges of the main body, respectively. The top plate is connected to the car roof of the car body, and the bottom plate is connected to the front wall of the car body.

[0008] As a further optional solution, the top plate has a first connecting plate extending downward from its edge, the bottom plate has a second connecting plate extending upward from its edge, and the lintel decorative panel is connected to the first connecting plate and the second connecting plate.

[0009] As a further optional solution, the transmission mechanism includes a drive component and a linkage component, wherein the door operator and the drive component are disposed on the inner side of the main board body, and the linkage component is disposed on the outer side of the main board body; The drive assembly includes a connecting member that reciprocates and is driven by the gantry crane; The linkage assembly includes two first transmission wheels and a first transmission belt wound around the two first transmission wheels; The main board body is provided with a clearance hole, at least a portion of the connector extends to the outside of the main board body through the clearance hole, and the connector is fixedly connected to the first transmission belt.

[0010] As a further optional solution, the drive assembly also includes two second drive wheels and a second drive belt wound around the two second drive wheels, the door motor being connected to one of the second drive wheels, and the second drive belt being drively connected to the connector.

[0011] As a further optional solution, the outer side of the main body is provided with a support strip for supporting the door hanger.

[0012] As a further optional solution, the motherboard body is a one-piece structure, and the support strip is formed by bending.

[0013] As a further optional solution, the top plate is bolted to the car roof of the car body; The base plate is bolted to the front wall of the car body.

[0014] As a further optional solution, the lintel decorative panel is bolted to the first connecting plate and the second connecting plate respectively.

[0015] Secondly, the technical solution provided by this utility model includes: An elevator comprising any of the above-mentioned integrated elevator door operator and lintel structure.

[0016] Compared with the prior art, this application has at least the following advantages: By directly connecting the door operator base plate of the door operator assembly to the front wall and top of the car body, there is no need to configure the long bracket required by traditional installation methods or rely on the door lintel reinforcement as the installation base. This saves the material cost, processing cost and assembly cost of the bracket, while simplifying the installation process and reducing the overall production and installation cost.

[0017] The gantry crane assembly forms a rigid, integral structure connected to the car body, completely eliminating the cantilever design of traditional installations. This connection method can evenly transmit the forces exerted by the gantry crane during operation to the front wall and roof of the car body, effectively avoiding operational vibrations, abnormal noises, or structural loosening after long-term use caused by the cantilever structure, significantly improving the overall stability and service life of the gantry crane installation.

[0018] By integrating the door operator assembly above the entrance and exit of the car body, and with the detachable lintel decorative panel inside the door operator assembly, maintenance can be performed by simply removing the lintel decorative panel and directly operating the door motor and transmission mechanism inside the car. No operator is required to stand on the car roof or cooperate outside the hall. A single person can complete the maintenance work, which greatly simplifies the operation process, improves the efficiency of installation and maintenance, and reduces the cost of manual cooperation and the risk of operation safety.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] refer to Figure 1-6 An embodiment of this utility model illustrates an integrated structure of elevator door operator and lintel, including a door operator assembly 1 disposed above the entrance / exit of the car body 100; the door operator assembly 1 includes a door operator base plate 11311, on which a door motor 12 and a transmission mechanism for drivingly connecting the door motor 12 and the door hanging plate 210 are provided; the bottom of the door operator base plate 11311 is connected to the front wall 110 of the car body 100, and the top of the door operator base plate 11311 is connected to the car roof 120 of the car body 100; a detachable lintel decorative panel 2 is provided on the inner side of the door operator assembly 1.

[0026] The door operator assembly 1 is positioned above the entrance / exit area (not marked in the figure) of the car body 100. The door operator base plate 11311 serves as the core load-bearing structure, with its bottom fixedly connected to the front wall 110 of the car and its top fixedly connected to the car roof 120, thus constructing a stable support frame. The door motor 12 is mounted on the door operator base plate 11311 and establishes a power transmission relationship with the door mounting plate 210 through a transmission mechanism. When the door motor 12 starts, power is transmitted to the door mounting plate 210 via the transmission mechanism, causing the door mounting plate 210 and the connected elevator door to open and close. Simultaneously, the lintel decorative panel 2 on the inner side of the door operator assembly 1 covers the inner side of the door operator assembly 1 (i.e., the side closest to the interior of the car body 100), serving both to decorate the area above the car entrance / exit and to provide some protection for the internal structure of the door operator assembly 1. It can also be directly disassembled for maintenance.

[0027] It should be noted that the lintel decorative panel 2, as a connecting component between the door operator assembly 1 and the interior decoration of the car, can be sized and shaped according to actual needs, adapting to the contour of the inner side of the door operator assembly 1. Generally, the lintel decorative panel 2 is required to cover the exposed areas of the door operator base plate 11311, the door motor 12, and the transmission mechanism, while maintaining consistency with the decorative style of the car's interior wall. The lintel decorative panel 2 can be connected to the door operator base plate 11311 or to the car body 100.

[0028] In this way, on the one hand, the door operator base plate 11311 is directly connected to the front wall 110 and the car top 120, without relying on the long bracket or door lintel reinforcement in the traditional installation method. This not only saves the cost of the bracket, but also avoids the stability problems caused by the cantilever structure, so that the force of the door operator during operation can be evenly transmitted to the car body 100, reducing vibration and abnormal noise, and extending service life. On the other hand, the detachable door lintel decorative panel 2 allows maintenance work to be carried out without having to be done on the car top 120 or outside the hall. After removing the decorative panel, the door motor 12 and transmission mechanism can be inspected inside the car, which can be completed by a single person, simplifying the process and reducing safety risks.

[0029] In some embodiments, the door operator base plate 11311 includes a vertically arranged main body 111, with a top plate 112 and a bottom plate 113 extending from the upper and lower edges of the main body 111, respectively. The top plate 112 is connected to the car roof 120 of the car body 100, and the bottom plate 113 is connected to the front wall 110 of the car body 100.

[0030] In this embodiment, as Figure 1 and Figure 3As shown, the main body 111 is vertical, with its upper and lower edges extending outwards to form a top plate 112 and a bottom plate 113, respectively. During installation, simply connect the top plate 112 to the car roof 120 and the bottom plate 113 to the front wall 110 of the car to secure the door operator bottom plate 11311 to the car body 100. The main body 111 serves as the mounting carrier for the door motor 12 and the transmission mechanism, providing a stable mounting reference for each component, ensuring accurate relative positioning of the door motor 12 and the transmission mechanism, and guaranteeing smooth power transmission.

[0031] The top plate 112 and the car roof 120 of the car body 100 can be bolted together; the bottom plate 113 and the front wall 110 of the car body 100 can be bolted together.

[0032] Furthermore, the top plate 112 has a first connecting plate 114 extending downward from its edge, and the bottom plate 113 has a second connecting plate 115 extending upward from its edge. The lintel decorative panel 2 is connected to the first connecting plate 114 and the second connecting plate 115.

[0033] Among them, such as Figure 1 and Figure 3 As shown, the first connecting plate 114 extending downward from the edge of the top plate 112 and the second connecting plate 115 extending upward from the edge of the bottom plate 113 form the installation support structure for the lintel decorative panel 2. During installation, the lintel decorative panel 2 is connected at its upper and lower ends to the first connecting plate 114 and the second connecting plate 115 respectively, ensuring that the lintel decorative panel 2 is stably fixed inside the door motor assembly 1. When it is necessary to inspect the internal structure of the door motor assembly 1, simply disconnect the lintel decorative panel 2 from the first connecting plate 114 and the second connecting plate 115 to remove the decorative panel, exposing the internal door motor 12 and transmission mechanism.

[0034] The lintel decorative panel 2 is bolted to the first connecting plate 114 and the second connecting plate 115 respectively.

[0035] In some embodiments, the outer side of the main board body 111 is provided with a support strip 1112 for supporting the door hanger 220. Preferably, the main board body 111 is a one-piece structure, and the support strip 1112 is bent into shape.

[0036] Specifically, during elevator door operation, the door rollers 220 on the door mounting plate 210 need to roll along a set trajectory to ensure smooth opening and closing of the elevator door. In this embodiment, the support bar 1112 on the outer side of the main body 111 serves as the support structure for the door rollers 220. The door rollers 220 are in direct contact with the support bar 1112. When the elevator door opens and closes, the door rollers 220 roll along the extension direction of the support bar 1112, and the support bar 1112 provides stable support and guidance for the door rollers 220.

[0037] The design of the support bar 1112 eliminates the need for additional support components for the door roller 220, simplifying the structure of the door operator assembly 1 and reducing the number of parts and assembly steps. At the same time, the support bar 1112 is integrated with the main body 111, providing higher support strength and ensuring the long-term stability of the door roller 220. This prevents the door roller 220 from shifting due to loose support structure, thus ensuring the safe operation of the elevator door.

[0038] In some embodiments, such as Figure 2 and Figure 6 As shown, the transmission mechanism includes a drive assembly 13 and a linkage assembly 14. The door operator and the drive assembly 13 are disposed on the inner side of the main board body, and the linkage assembly 14 is disposed on the outer side of the main board body. The drive assembly 13 includes a connecting member 131 that is driven by the door operator to reciprocate. The linkage assembly 14 includes two first transmission wheels 141 and a first transmission belt wound around the two first transmission wheels 141. The main board body 111 is provided with a clearance hole 1111, and at least a portion of the connecting member 131 extends to the outer side of the main board body 111 through the clearance hole 1111, and the connecting member 131 is fixedly connected to the first transmission belt.

[0039] Specifically, during actual operation, after the door motor 12 starts, it drives the drive assembly 13 to move, causing the connector 131 in the drive assembly 13 to reciprocate in a set direction. Since the connector 131 extends outward through the clearance hole 1111 on the main board 111 and is fixed to the first transmission belt, the reciprocating motion of the connector 131 can drive the first transmission belt to move synchronously. The first transmission belt is wound around two first transmission wheels 141, and its movement can drive the first transmission wheels 141 to rotate. Then, through the connection between the linkage assembly 14 and the door hanging plate 210, the power is transmitted to the door hanging plate 210, realizing the opening and closing of the elevator door.

[0040] The drive assembly 13 and the door motor 12 are located inside the main body 111, while the linkage assembly 14 is located on the outside, making the layout of the transmission mechanism components more reasonable and avoiding mutual interference. The transmission mechanism is divided into inner and outer sections on the main body 111, which effectively utilizes the space of the door motor assembly 1 and makes the overall structure more compact.

[0041] It should be noted that, in this embodiment, as Figure 2As shown, each of the two car doors 200 (the left car door 200 and the right car door 200) is connected to a door hanger 210. The door hanger 210 of the left car door 200 is fixedly connected to the upper section of the first transmission belt, and the door hanger 210 of the right car door 200 is fixedly connected to the lower section of the first transmission belt. When the first transmission belt moves clockwise under the drive of the connector 131, the upper section of the transmission belt drives the door hanger 210 of the left car door 200 to move to the left, thus opening the left car door 200. At the same time, the lower section of the transmission belt drives the door hanger 210 of the right car door 200 to move to the right, thus opening the right car door 200. When the first transmission belt moves counterclockwise, the upper section of the transmission belt drives the door hanger 210 of the left car door 200 to move to the right, and the lower section of the transmission belt drives the door hanger 210 of the right car door 200 to move to the left, thus closing both car doors 200. This connection method ensures that the two car doors 200 move synchronously in opposite directions.

[0042] In addition, in this embodiment, the first transmission belt can be made of steel wire rope, which has the characteristics of high strength and wear resistance, and can bear the weight of the door plate 210 and car door 200 for a long time, making it suitable for elevators that frequently open and close doors. In addition to steel wire rope, the first transmission belt can also be made of synchronous belt (such as polyurethane synchronous belt or rubber synchronous belt, which is suitable for scenarios with high transmission accuracy requirements), chain (such as roller chain or toothed chain, which is suitable for scenarios with large load capacity), or steel belt (such as stainless steel belt, which is suitable for scenarios with high corrosion resistance requirements), etc. The specific type can be flexibly selected according to the elevator's load capacity, operating frequency, and usage environment.

[0043] In some embodiments, to facilitate the reciprocating motion of the connector 131, such as Figure 5 As shown, the drive assembly 13 further includes two second drive wheels 132 and a second drive belt 142133 wound around the two second drive wheels 132. The door motor 12 is connected to one of the second drive wheels 132, and the second drive belt 142133 is connected to the connector 131 in a transmission connection.

[0044] When the door motor 12 starts, its output shaft drives the connected second transmission wheel 132 to rotate. This second transmission wheel 132 drives another second transmission wheel 132 to rotate synchronously via a second transmission belt 142133, causing the second transmission belt 142133 to move along a set trajectory. Since the second transmission belt 142133 is connected to the connecting member 131, the movement of the second transmission belt 142133 can drive the connecting member 131 to reciprocate. Furthermore, through the connection between the connecting member 131 and the first transmission belt, the power is transmitted to the linkage component 14, ultimately realizing the opening and closing action of the elevator door.

[0045] In this embodiment, the second transmission belt 142133 can preferably be a synchronous belt (such as a rubber synchronous belt or a polyurethane synchronous belt); in addition to a synchronous belt, the second transmission belt 142133 can also be a flat belt, a multi-ribbed belt or a chain, etc., depending on actual needs.

[0046] This utility model also provides an elevator, including any of the above-mentioned elevator door operator and lintel integrated structure.

[0047] In summary, this application discloses an integrated structure of elevator door operator and lintel, as well as an elevator. By directly connecting the door operator base plate 11311 of the door operator assembly 1 to the front wall 110 and car top 120 of the car body 100, it eliminates the need for the long brackets required by traditional installation methods or the reliance on lintel reinforcing ribs as the installation base. This saves on the material cost, processing cost, and assembly cost of the brackets, while simplifying the installation process and reducing the overall production and installation costs.

[0048] The door operator assembly 1 forms an integral structure rigidly connected to the car body 100, completely eliminating the cantilever design of traditional installations. This connection method can evenly transmit the force of the door operator during operation to the front wall 110 and car top 120 of the car body 100, effectively avoiding operating vibration, abnormal noise, or structural loosening after long-term use caused by the cantilever structure, and significantly improving the overall stability and service life of the door operator installation.

[0049] By integrating the door operator assembly 1 above the entrance and exit of the car body 100, and with the door lintel decorative panel 2 on the inner side of the door operator assembly 1 being detachable, maintenance can be performed by simply removing the door lintel decorative panel 2, allowing direct operation of the door motor 12 and transmission mechanism from inside the car. No operator is required to stand on the car roof 120 or cooperate outside the hall; a single person can complete the maintenance work, greatly simplifying the operation process, improving installation and maintenance efficiency, and reducing labor collaboration costs and operational safety risks.

[0050] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0051] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
