Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a steel belt ladder upper beam structure that is easy to inspect and maintain. Background Technology

[0002] With the acceleration of urbanization and the improvement of residents' living standards, the demand for home elevators as a vertical transportation solution has increased significantly in villas, duplexes, and the renovation of old residential areas. Among them, due to limitations in building structure or floor height, the market share of low-rise and top-floor home elevators has been increasing year by year, placing higher demands on space utilization, aesthetics, and ease of maintenance.

[0003] Currently, in the mainstream design of traditional ceiling-mounted steel belt elevators, the drive system's sheaves typically employ two arrangement methods:

[0004] 1. Exposed installation: The rope pulley is directly fixed to the outside of the upper beam. Although this method simplifies the initial installation, it increases the height of the top floor (requiring additional space to be reserved for the rope pulley), and the exposed mechanical structure detracts from the overall aesthetics of the shaft, making it difficult to meet the decoration requirements of high-end residences.

[0005] 2. Embedded installation within the abdominal cavity: The rope pulley is hidden inside the abdominal cavity of the upper beam. Although this design optimizes the appearance and reduces the height of the top floor, it has significant drawbacks: maintenance or replacement of the rope pulley requires disassembling the entire upper beam assembly, which is complex and time-consuming (requiring an average of 2-3 people working together for more than 4 hours), resulting in high labor costs, long downtime for users, and seriously affecting the user experience.

[0006] Against this background, the present invention proposes a new technical solution. Utility Model Content

[0007] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a steel-belt ladder upper beam structure that is easy to maintain, and the technical solution adopted is as follows:

[0008] A steel-strapped ladder upper beam structure for easy maintenance includes an upper beam with a cavity in which a rope pulley is detachably mounted; semi-open receiving cavities are provided on both sides of the upper beam, and mounting portions extend axially from both ends of the rope pulley, the mounting portions being disposed within the semi-open receiving cavities and vertically limited by them; a fixed limiting structure is provided between the semi-open receiving cavities and the mounting portions, the fixed limiting structure restricting the movement of the mounting portions within the semi-open receiving cavities, and after the restriction is released, the mounting portions can move in an arc in the horizontal direction within the semi-open receiving cavities until they are completely withdrawn from the semi-open receiving cavities.

[0009] According to an embodiment of the present invention, a steel-belt ladder upper beam structure that is easy to maintain includes a semi-open accommodating cavity, which is a long strip-shaped mounting groove provided on the side wall of the upper beam, and the long strip-shaped mounting groove is connected to the abdominal cavity of the upper beam.

[0010] According to an embodiment of the present invention, a steel belt ladder upper beam structure that is easy to maintain includes a fixed limiting structure comprising at least one fixing plate, the end of which is fixedly connected to the side wall of the upper beam, and the middle part of which is limitedly connected to the mounting part of the rope wheel.

[0011] According to an embodiment of the present invention, a steel-strapped ladder upper beam structure that is easy to maintain includes a fixing plate fixedly connected to the outer end face of the side wall of the upper beam. The fixing plate is located outside the elongated mounting groove, and the elongated mounting groove is at least partially covered by the fixing plate. A limiting hole is opened on the fixing plate, and the mounting part is inserted through the limiting hole for limiting connection.

[0012] According to an embodiment of the present utility model, a steel belt ladder upper beam structure that is easy to maintain includes an installation part having a slot thereon. The installation part passes through a limiting hole from the elongated installation slot and protrudes to the outside of the fixing plate. A limiting plate is detachably installed on the outer side of the fixing plate. After installation, the side of the limiting plate is snapped into the slot of the installation part to limit the installation part.

[0013] According to an embodiment of the present invention, a steel-strapped ladder upper beam structure that is easy to maintain has a fixed plate with a length greater than the length of the elongated mounting groove.

[0014] According to an embodiment of the present invention, a steel-strapped ladder upper beam structure that is easy to maintain includes a pair of fixing plates; the mounting part is provided with a slot thereon, and the mounting part passes through the limiting hole from the elongated mounting groove and protrudes to the outside of the fixing plate; the pair of fixing plates are installed on the outer side of the upper beam and are respectively located on both sides of the mounting part, wherein the side of one fixing plate abuts against the mounting part, and the side of the other fixing plate is inserted into the slot of the mounting part to limit the mounting part.

[0015] According to an embodiment of the present invention, a steel belt ladder upper beam structure that is easy to maintain is provided, wherein the mounting part is a connecting shaft disposed on the side of the rope wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] Under normal conditions, the mounting parts at both ends of the rope pulley are restricted by the fixed limiting structure and cannot move within the semi-open cavity, ensuring the stability of the rope pulley installation. When maintenance is required, the restriction of the fixed limiting structure is released, and the mounting parts of the rope pulley can move horizontally in an arc within the semi-open cavity, i.e., rotate horizontally, until the mounting parts are completely removed from the semi-open cavity. In practice, rotating 90° horizontally around the midpoint of the rope pulley will allow the mounting parts at both ends to exit the semi-open cavity simultaneously. This allows the rope pulley to be removed without disassembling the upper beam, greatly shortening maintenance time by more than 60% and significantly improving maintenance efficiency.

[0032] This utility model provides a steel-strapped ladder upper beam structure that is easy to inspect and maintain, such as... Figures 1 to 6 In the illustrated embodiments one and two, an upper beam 10 is included, the upper beam 10 having a cavity 20, in which a rope pulley 30 is detachably installed; semi-open receiving cavities are provided on both sides of the upper beam 10, and mounting portions extend axially from both ends of the rope pulley 30, the mounting portions being disposed within the semi-open receiving cavities and vertically limited by them; a fixed limiting structure is provided between the semi-open receiving cavities and the mounting portions, the fixed limiting structure restricting the movement of the mounting portions within the semi-open receiving cavities, and after the restriction is released, the mounting portions can move in an arc in the horizontal direction of the semi-open receiving cavities until they are completely withdrawn from the semi-open receiving cavities.

[0033] Under normal conditions, the mounting portions at both ends of the rope pulley 30 are limited by the fixed limiting structure and cannot move within the semi-open receiving cavity, ensuring the stability of the rope pulley 30 installation. When maintenance is required, the restriction of the fixed limiting structure is released, and the mounting portions of the rope pulley 30 can move horizontally in an arc within the semi-open receiving cavity, i.e., rotate horizontally, until the mounting portions are completely removed from the semi-open receiving cavity. In specific implementation, rotating horizontally 90° with the midpoint of the rope pulley 30 as the axis, the mounting portions at both ends can be simultaneously removed from the semi-open receiving cavity. This allows the rope pulley 30 to be removed without disassembling the upper beam 10, greatly shortening the maintenance time by more than 60% and significantly improving maintenance efficiency.

[0034] like Figures 1 to 6 In the first and second embodiments shown, the semi-open receiving cavity is a long strip-shaped mounting groove 40 provided on the side wall of the upper beam 10. The long strip-shaped mounting groove 40 is connected to the abdominal cavity 20 of the upper beam 10. The length of the long strip-shaped mounting groove 40 is such that the mounting part of the rope wheel 30 can be dislodged from the long strip-shaped mounting groove 40 after horizontal rotation.

[0035] like Figures 1 to 6 In the first and second embodiments shown, the fixed limiting structure includes at least one fixed plate 70. The end of the fixed plate 70 is fixedly connected to the side wall of the upper beam 10, and the middle part is limitedly connected to the mounting part of the rope wheel 30. The fixed plate 70 is fixed to the side of the upper beam 10 and also has a restraint and limiting relationship with the mounting part, thereby restricting the movement of the mounting part in the elongated mounting groove 40.

[0036] In Embodiment 1 of this utility model, as Figure 1 , 2 As shown in Figure 3, the fixed limiting structure includes a fixing plate 70 detachably fixed to the outer end face of the side wall of the upper beam 10. The fixing plate 70 is located outside the elongated mounting groove 40, and the length of the fixing plate 70 is greater than the length of the elongated mounting groove 40. The elongated mounting groove 40 is completely covered by the fixing plate 70, and the elongated mounting groove 40 is not exposed when viewed from the outside of the upper beam 10. A limiting hole 80 is provided on the fixing plate 70, and the mounting part passes through the limiting hole 80 for limiting connection. In this embodiment, the fixing plate 70 is fixed to the outer surface of the upper beam 10 by screws, covering the outer side of the elongated mounting groove 40. The mounting part of the rope wheel 30 passes through the limiting hole 80 from the inside to the outside, and is simultaneously clamped in the limiting hole 80 to limit the mounting part.

[0037] To prevent the mounting part from loosening within the limiting hole 80 and affecting the stability of the rope pulley 30 installation, in Embodiment 1 of this utility model, as follows: Figure 1 , 2As shown in Figure 3, the mounting part has a slot 60 thereon. The mounting part passes through the limiting hole 80 from the elongated mounting groove 40 and is exposed on the outside of the fixing plate 70. A limiting plate 90 is detachably installed on the outer side of the fixing plate 70. After installation, the side of the limiting plate 90 is inserted into the slot 60 of the mounting part to limit the mounting part. After the mounting part is fitted into the limiting hole 80 and limited, one side of it is clamped by the limiting plate 90 to strengthen its limitation.

[0038] In the second embodiment of this utility model, as Figure 4 , 5 As shown in Figure 6, the fixed limiting structure includes a pair of fixing plates 70; the mounting part is provided with a slot 60 thereon, and the mounting part passes through the limiting hole 80 from the elongated mounting groove 40 and is exposed on the outside of the fixing plate 70; the pair of fixing plates 70 are installed on the outer side of the upper beam and are respectively located on both sides of the mounting part, wherein the side of one fixing plate 70 abuts against the mounting part, and the side of the other fixing plate 70 is inserted into the slot 60 of the mounting part to limit the mounting part.

[0039] The mounting part of the rope pulley 30 is exposed after passing through the elongated mounting groove 40. Two fixing plates 70 are placed on both sides of the mounting part, with one side pressing against the limiting position and the other side being clamped into its locking groove 60 for clamping and limiting. After the elongated mounting groove 40 limits the vertical direction of the mounting part, the two sides of the fixing plates 70 limit its horizontal direction of action.

[0040] In Embodiments 1 and 2 of this utility model, as follows: Figures 1 to 6 As shown, the mounting part is a connecting shaft 50 located on the side of the rope pulley 30.

[0041] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
