Backpack frame villa elevator

Abstract

A knapsack frame villa elevator comprises a lift car, a beam frame and a bracket. The beam frame and the bracket are both frames shaped like a Chinese character'hui '. The bracket comprises two long plates arranged in parallel and two short plates arranged in parallel and located between the two long plates. The ends, facing the beam frame, of the two long plates are each provided with a connecting end, and the sides, facing the short plates, of the connecting ends are each provided with a deformation groove. According to the knapsack frame villa elevator, the lift car is supported by the L-shaped dragging plate formed by the beam frame and the bracket, so that the traction force on the lift car in the horizontal direction is balanced, and the lift car is prevented from inclining due to the traction force on one side. The deformation grooves can avoid local stress sudden change, so that stress concentration is reduced, the long plate is prevented from being broken, and the service life of the bracket is prolonged. The concentric-square-shaped beam frame and the bracket can reduce the load bearing of the beam frame. And the rectangular-ambulatory-plane beam frame expands the installation space of other parts.

Description

Technical Field

[0001] This utility model relates to the field of elevator equipment technology, and in particular to a backpack frame villa ladder. Background Technology

[0002] Backpack-frame villa stairs are a type of home elevator design. Their structural feature is a guide rail on one side and a load-bearing support frame at the bottom to support the weight of the entire car during vertical movement. This design resembles a forklift used for moving goods in a warehouse, and because the load is primarily on one side, it's similar to a person carrying a backpack, hence the name "backpack-frame structure." However, existing backpack-frame villa stairs may experience metal fatigue at the bottom after prolonged use, resulting in a shorter lifespan for the support frame. Summary of the Invention

[0003] In view of this, the present invention provides a backpack frame villa ladder to solve the above problems.

[0004] A backpack-style villa ladder includes a car, a beam frame disposed on one side of the car, and a bracket disposed at one end of the beam frame. Both the beam frame and the bracket are U-shaped frames. The beam frame has two parallel side beams on both sides, and a lower crossbeam on the side of the two side beams facing the bracket. The ends of the two side beams away from the bracket protrude from the top of the car and are fixedly connected to an upper crossbeam. The bracket includes two parallel long plates and two parallel short plates located between the two long plates. Each of the two long plates has a connecting end at the end facing the beam frame, and each connecting end protrudes from the connection point between the two short plates and the long plates. The connecting end has a deformation groove on the side facing the short plate.

[0005] Furthermore, the beam frame is formed by connecting four crossbeams end to end and fixing them together with screws. The beam frame is located on the side of the car away from the elevator door.

[0006] Furthermore, a middle crossbeam is provided in the middle section of the beam frame, and a traction module is fixedly mounted between the middle crossbeam and the car.

[0007] Furthermore, at least two U-shaped plates are fixedly installed on the side of the upper crossbeam away from the side beam by screws, and an L-shaped plate is fixedly installed on the side of the U-shaped plate away from the upper crossbeam by screws. One side of the L-shaped plate is fixedly installed on the top of the car by screws.

[0008] Furthermore, the two long plates and the two short plates are connected end to end and fixed together with screws.

[0009] Furthermore, the two connecting ends are fixedly connected to one side of the two side beams and both ends of the lower crossbeam by at least eight screws respectively.

[0010] Compared with existing technologies, the backpack frame villa ladder provided by this utility model supports the car through an L-shaped support plate formed by the beam frame and the bracket, thereby balancing the traction force on the car in the horizontal direction and preventing the car from tilting due to traction force on one side. The deformation groove avoids local stress abrupt changes, thereby reducing stress concentration, preventing the long plate from breaking, and improving the service life of the bracket. The U-shaped beam frame and bracket can reduce their own load. Moreover, the U-shaped beam frame expands the installation space of other components, providing space for components such as the traction module. Attached Figure Description

[0016] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0017] like Figure 1 The diagram shown is a structural schematic of the backpack frame villa ladder provided by this utility model. The backpack frame villa ladder includes a car 10, a beam frame 20 disposed on one side of the car 10, and a bracket 30 disposed at one end of the beam frame 20. It is conceivable that the backpack frame villa ladder also includes other functional modules, such as screw modules, traction modules, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0018] Please refer to the following: Figures 2 to 5The car 10 is a box-shaped space on the elevator, used to carry and transport people and goods. The structure and function of the car 10 itself are existing technologies and will not be described in detail here.

[0019] The beam frame 20 is a U-shaped frame, formed by four horizontal beams connected end to end and fixed together with screws. The beam frame 20 is located on the side of the car 10 away from the elevator door. The U-shaped beam frame 20 corresponds to the four corners of the car 10. This U-shaped beam frame 20 expands the installation space for other components, providing space for components such as the traction module, while also reducing its own load.

[0020] The beam frame 20 has two parallel side beams 21 on both sides. The side of the two side beams 21 facing the bracket 30 is a lower crossbeam 22. The side beams 21 and the lower crossbeam 22 are used to fix the bracket 30, so that the beam frame 20 and the bracket 30 form an L-shaped support plate to support the car 10. The fixing method between the lower crossbeam 22 and the bracket 30 will be described below.

[0021] A central crossbeam 23 is provided in the middle section of the two side beams 21. A traction module is fixedly mounted between the central crossbeam 23 and the car 10 to traction the car 10 and the beam frame 20, thereby realizing their lifting and lowering functions.

[0022] One end of each of the two side beams 21, away from the bracket 30, protrudes from the top of the car 10 and is fixedly mounted with an upper crossbeam 24. At least two U-shaped plates 25 are fixedly mounted on the side of the upper crossbeam 24 away from the side beams 21 by screws. An L-shaped plate 26 is fixedly mounted on the side of the U-shaped plate 25 away from the upper crossbeam 24 by screws. One side of the L-shaped plate 26 is fixedly mounted on the top of the car 10 by screws, thus fixing the top of the car 10 together with the upper crossbeam 24.

[0023] The bracket 30 is located at the bottom of the car 10, and includes two parallel long plates 31 and two parallel short plates 32 located between the two long plates 31.

[0024] The two long plates 31 and the two short plates 32 are connected end to end and fixed together with screws to form a U-shaped frame. Each of the two long plates 31 has a connecting end 33 at its end facing the beam frame 20. The two connecting ends 33 protrude from the connection points between the two short plates 32 and the long plates 31, facilitating connection with the beam frame 20 and also allowing the bracket 30 to support the car 10.

[0025] The two connecting ends 33 are fixedly connected to one side of the two side beams 21 and both ends of the lower crossbeam 22 by at least eight screws, so that the beam frame 20 and the bracket 30 form an L-shaped support plate to support the car 10. In this way, when the traction module pulls the elevator, the bracket 30 can support the car 10, thereby balancing the traction force on the car 10 in the horizontal direction and preventing the car 10 from tilting due to the traction force on one side.

[0026] The connecting end 31 has a deformation groove 34 on the side facing the short plate 32. The deformation groove 34 is an arc groove. By replacing sharp corners with rounded corners, the change in geometry is made more gradual. This smooth transition allows the force lines to gradually change direction, avoiding stress abrupt changes in local areas, thereby reducing stress concentration and preventing the long plate 31 from breaking.

[0027] Compared with the prior art, the backpack frame villa ladder provided by this utility model supports the car 10 through the L-shaped support plate formed by the beam frame 20 and the bracket 30, thereby balancing the traction force on the car 10 in the horizontal direction and preventing the car 10 from tilting due to the traction force on one side. The deformation groove 34 avoids the formation of local stress abrupt changes, thereby reducing stress concentration, preventing the long plate 31 from breaking, and improving the service life of the bracket 30. The U-shaped beam frame 20 and the bracket 30 can reduce their own load. Moreover, the U-shaped beam frame 20 expands the installation space of other components, providing space for the installation of components such as the traction module.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
