Description

Technical Field

[0001] This application relates to the field of elevator components, and in particular to a high-strength vertical beam column for passenger elevator car frame. Background Technology

[0002] As a vertical transportation tool within buildings, the performance of elevators, including safety, reliability, efficiency, and comfort, directly impacts the user experience. For passenger elevators, the car is the key component for transporting passengers and goods, while the car frame is the load-bearing structure, and its structural strength and stability are crucial for the safe operation of the elevator.

[0003] In the industry, the vertical beams and columns used in passenger elevator car frames are typically manufactured by cold-bending hot-rolled steel plates into U-shaped columns. Rectangular holes for guide shoes are machined at both ends, and round holes for structural components are machined on both sides and ends. This column structure is simple and easy to manufacture. When faced with insufficient structural strength of the car frame columns, the industry typically uses rectangular reinforcing plates installed on both sides of the columns to increase their strength. This method can improve the strength of the columns to a certain extent and ensure the stability of the car frame.

[0004] While this rectangular reinforcing plate can improve the strength of the column, its rectangular shape not only occupies space in the car frame but also increases air resistance during high-speed operation, thus increasing the cost of use. Utility Model Content

[0005] In order to improve the strength of the column by installing rectangular reinforcing plates, but the rectangular reinforcing plates occupy the space of the car frame and increase the air resistance of the car frame during high-speed operation, this application provides a high-strength vertical beam column for passenger elevator car frames.

[0006] The high-strength vertical beam column for passenger elevator car frame provided in this application adopts the following technical solution:

[0007] A high-strength vertical beam column for passenger elevator car frame includes a vertical beam column body. A left support reinforcing plate and a right support reinforcing plate are respectively provided on the bottom side wall of the vertical beam column body. The left support reinforcing plate and the right support reinforcing plate are both arranged in a triangular wing shape. The short side of the left support reinforcing plate is located at its top end to reduce the air resistance generated when the left support reinforcing plate moves.

[0008] By adopting the above technical solution, both the left and right support reinforcing plates have a triangular wing structure and are arranged with the short side facing upwards. On the one hand, the left and right support reinforcing plates can increase the strength of the vertical beam column body without occupying too much additional space in the car frame. On the other hand, the left and right support reinforcing plates can also effectively reduce the air resistance generated when the left and right support reinforcing plates move, thereby reducing the air resistance of the car frame during high-speed operation.

The first plate is then installed on the vertical beam column body, thereby realizing the installation of the left support reinforcement plate on the vertical beam column body.

[0011] Optionally, the right support reinforcing plate includes a fourth plate connected to the vertical beam column body and a fifth plate integrally formed on the fourth plate, wherein the fourth plate and the fifth plate are arranged perpendicularly.

[0012] By adopting the above technical solution, the fourth and fifth plates are integrally formed and perpendicular to each other, constituting a structurally stable, triangular wing-shaped right support reinforcement plate. The fourth plate is then installed on the vertical beam column body, thereby realizing the installation of the right support reinforcement plate on the vertical beam column body.

[0013] Optionally, the second plate is provided with a groove to reduce the weight of the left support reinforcement plate.

[0014] By adopting the above technical solution, the trough can reduce the overall weight of the left support reinforcing plate, thereby enhancing the rigidity and structural strength of the car frame and achieving energy saving and consumption reduction.

[0015] Optionally, a guide shoe mounting hole is provided at the top center of the vertical beam column body, and the guide shoe mounting hole is used to install a guide shoe on the vertical beam column body.

[0016] By adopting the above technical solution, the guide shoe mounting hole can be used to install the guide shoe on the vertical beam column body, thereby providing an installation position for the guide shoe, which is conducive to ensuring the safe operation of the elevator.

[0017] Optionally, the top side wall of the vertical beam column body is provided with an upper beam mounting hole, which is used to install the upper beam on the vertical beam column body.

[0018] By adopting the above technical solution, the upper beam can be installed on the vertical beam column body using the upper beam mounting holes, thereby enhancing the structural stability of the connection between the upper beam and the vertical beam column body, which is conducive to ensuring the safe operation of the elevator.

[0019] Optionally, a car frame mounting hole is provided on the lower side wall of the middle part of the vertical beam column body, and the car frame mounting hole is used to install the car frame on the vertical beam column body.

[0020] By adopting the above technical solution, the car frame can be installed on the vertical beam column body using the car frame mounting holes, providing an installation position for the car frame, thereby enhancing the structural stability of the connection between the car frame and the vertical beam column body, which is conducive to ensuring the safe operation of the elevator.

[0021] Optionally, a lower beam mounting hole is provided on the bottom side wall of the vertical beam column body, and the lower beam mounting hole is used to install the lower beam on the vertical beam column body.

[0022] By adopting the above technical solution, the lower beam can be installed on the vertical column body using the lower beam mounting holes, thereby enhancing the structural strength and stability of the passenger elevator car frame.

[0023] Optionally, the vertical beam column body has connection holes on both sides. The connection holes are located between the car frame mounting hole and the lower beam mounting hole. One side of the connection hole is fixedly connected to the first plate of the left support reinforcing plate by fasteners, and the other side of the connection hole is fixedly connected to the fourth plate of the right support reinforcing plate by fasteners.

[0024] By adopting the above technical solution, the left support reinforcing plate is installed on the vertical beam column body through fasteners and connecting holes, and the right support reinforcing plate is installed on the vertical beam column body.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a high-strength vertical beam column for passenger elevator car frame.

[0039] Reference Figure 1 and Figure 2 A high-strength vertical beam column for a passenger elevator car frame includes a vertical beam column body 1, a left support reinforcing plate 2, and a right support reinforcing plate 3. The left support reinforcing plate 2 and the right support reinforcing plate 3 are respectively disposed on the bottom sidewall of the vertical beam column body 1, and both are arranged in a triangular wing shape. Furthermore, the short side of the left support reinforcing plate 2 is located at its top, and the short side of the right support reinforcing plate 3 is also located at its top.

[0040] Reference Figure 2 The triangular wing-shaped structure is more in line with aerodynamic principles. Compared with traditional rectangular reinforcing plates, installing left support reinforcing plates 2 and right support reinforcing plates 3 on the vertical beam column body 1 can effectively reduce air resistance. This not only enhances the structural strength of the vertical beam column body 1 but also reduces air resistance generated by the car frame during high-speed operation.

[0041] In this embodiment, the vertical beam column body 1 is an equilateral right-angled U-shaped structure, and the material is usually Q-235A hot-rolled steel plate, which is formed by cutting, room temperature bending, drilling and other processes.

[0042] Reference Figure 3 A guide shoe mounting hole 5 is provided at the top center of the vertical beam column body 1 for installing the guide shoe on the vertical beam column body 1, so that the vertical beam column body 1 can be precisely connected with the guide shoe.

The four corners of the rectangular square hole are rounded with inner arcs. In addition, four circular holes with equal spacing and equal diameter are machined on both sides of the long side of the rectangular square hole. Two circular holes are machined on each side, and the line connecting the centers of the two circular holes on the same side is parallel to the center line of the rectangular square hole along its length. The diameter of the holes matches the fastening screw of the guide shoe seat.

The diameter of the holes is consistent with that of the upper beam connection hole 9, which facilitates the installation of the upper beam.

[0045] Reference Figure 4 A car frame mounting hole 7 is provided on the lower side wall of the middle part of the vertical beam column body 1 for mounting the car frame on the vertical beam column body 1, ensuring a stable connection between the vertical beam column body 1 and the car frame. In this embodiment, there are two car frame mounting holes 7, which are symmetrically opened on both sides of the right-angled U-shape of the vertical beam column body 1, and their diameters are consistent with the circular holes on the side plate of the car frame.

The connecting hole 9 on one side is used to install the left support reinforcing plate 2 on the vertical beam column body 1, and the connecting hole 9 on the other side is used to install the right support reinforcing plate 3 on the vertical beam column body 1. In this embodiment, there are eight connecting holes 9, with four on each side of the vertical beam column body 1.

[0048] Reference Figure 5 The left support reinforcing plate 2 includes a first plate 21 connected to the vertical beam column body 1, a second plate 22 integrally formed on the first plate 21, and a third plate 23 integrally formed on the second plate 22. The first plate 21 and the second plate 22 are arranged perpendicularly, the second plate 22 and the third plate 23 are arranged perpendicularly, and the first plate 21 and the third plate 23 are also arranged perpendicularly.

The second plate 22 is triangular in shape, and the long side of the triangle of the second plate 22 is processed into a 90° convex bend to form the first plate 21. The short side of the triangle of the second plate 22 is processed into a 90° convex bend near the end to form the third plate 23, and the third plate 23 has an isosceles trapezoidal structure.

[0050] Reference Figure 5 Three semi-circular rectangular slots of equal diameter and equidistant spacing are vertically machined on the plane of the first plate 21. The line connecting the centers of these slots coincides with the center line of the length direction of the first plate 21. Furthermore, the width and spacing of these slots are consistent with the dimensions of the three connecting holes 9 on the lower left side of the vertical beam column body 1. The first plate 21 of the left support reinforcing plate 2 is tightly fixed to the vertical beam column body 1 using three fasteners. The fasteners include hexagonal bolts, hexagonal nuts, and washers.

The line connecting the centers of these slots is parallel to the short side of the second plate 22, and the diameter and spacing of the slots are consistent with the horizontal support side holes above the lower beam, so as to facilitate the installation of the horizontal support side above the lower beam on the left support reinforcing plate 2.

[0052] Reference Figure 5A circular hole is vertically machined on the central plane of the third plate 23. The diameter of the hole is consistent with the circular hole on the side of the lower beam of the car frame, so as to facilitate the installation of the side of the lower beam of the car frame on the left support reinforcing plate 2.

[0053] Reference Figure 5 A groove 4 is vertically formed in the middle of the second plate 22. The groove 4 can reduce the overall weight of the left support reinforcing plate 2, thereby enhancing the rigidity and structural strength of the car frame and achieving energy saving and consumption reduction.

The line connecting the centers of these slots is parallel to the short side of the fifth plate 32. The diameter and spacing of these slots are consistent with the horizontal support side holes above the lower beam, which facilitates the installation of the horizontal support side above the lower beam onto the right support reinforcing plate 3.
