Description

Technical Field

[0001] This utility model relates to the field of barrier-free lifting platform technology, and in particular to a wheelchair lifting device and its lifting platform. Background Technology

[0002] A wheelchair lifting device is a barrier-free lifting platform device, which mainly consists of a motor, a rotating shaft, and a lifting platform. The motor drives the shaft to rotate, which in turn drives the traction belt to lift or lower the wheelchair.

[0003] Because the lifting platform needs to bear the weight of the human body and the wheelchair, the load-bearing requirements of the lifting platform are relatively high. In order to ensure the load-bearing capacity and structural strength of the lifting platform, cold plate welding is often used during production and assembly. Cold plate welding has the following disadvantages: (1) Cold plate welding requires additional anti-rust spraying treatment, and the material cost is high; (2) Cold plate has a high density, and the chassis made is heavy, which affects the portability and energy consumption of the equipment; (3) It requires multiple processes such as spot welding and spraying, resulting in low production efficiency, and spraying may cause environmental pollution. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a wheelchair lifting device and its lifting platform, which is lightweight and has high structural strength, effectively reducing production and transportation costs.

[0005] To address the aforementioned problems, this utility model proposes a lifting platform for a wheelchair lifting device, comprising a platform mounting frame, a plate surface, and strip-shaped reinforcing members;

[0006] The platform mounting frame has mounting grooves on both sides. Multiple strip-shaped reinforcing members are arranged at predetermined intervals along the front to rear side of the platform mounting frame, and the strip-shaped reinforcing members are parallel to each other. Both ends of the strip-shaped reinforcing members are embedded in the mounting grooves and are fixedly connected to the bottom of the mounting grooves. The plate surface is provided on the platform mounting frame and abuts against the surface of the strip-shaped reinforcing members.

[0007] The platform mounting frame has vertical baffles on both sides and the rear side, and the baffles are perpendicular to the plate surface.

[0008] As an improvement to the above technical solution, the strip reinforcement includes a first support wall perpendicular to the plane direction of the plate surface, and the two sides of the first support wall are bent in the same direction to form a second support wall, the bending direction of the second support wall being parallel to the plate surface.

[0009] As an improvement to the above technical solution, the number of strip-shaped reinforcing members is 5-8.

[0010] As an improvement to the above technical solution, the surface of the plate is provided with a plurality of perforated holes arranged at predetermined intervals.

[0011] As an improvement to the above technical solution, a ramp is provided on the front side of the platform mounting frame.

[0012] As an improvement to the above technical solution, the plate surface is provided with at least one blocking protrusion from the front to the rear side, and the axial direction of the blocking protrusion is parallel to the axial direction of the strip reinforcement.

[0013] As an improvement to the above technical solution, the cross-sectional area of ​​the blocking protrusion gradually decreases from the bottom to the top;

[0014] At least one of the blocking protrusions is provided on the front edge of the plate surface, and pulleys are provided on both sides of the surface of the slope.

[0015] Accordingly, this utility model embodiment also provides a wheelchair lifting device, including the lifting platform described above.

[0016] The following are the beneficial effects of implementing this utility model:

[0017] This utility model includes a platform mounting frame, a plate surface, and strip-shaped reinforcing members. Multiple strip-shaped reinforcing members are arranged at predetermined intervals along the front to rear side of the platform mounting frame. Both ends of each strip-shaped reinforcing member are embedded in the mounting groove. The plate surface is disposed on the platform mounting frame and abuts against the surfaces of the strip-shaped reinforcing members. By setting multiple strip-shaped reinforcing members at the bottom of the plate surface, the assembly method replaces traditional welding, further avoiding the risk of thermal deformation, and is suitable for lifting scenarios with high precision requirements. It solves the problem of cold-plate welding in existing technologies, which results in excessive weight of the lifting platform and requires spot welding and spraying processes, effectively reducing production and transportation costs.

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0024] See Figures 1 to 5 As shown, this utility model embodiment provides a lifting platform for a wheelchair lifting device, including a platform mounting frame 1, a plate surface 2, and a strip-shaped reinforcing member 3.

[0025] This embodiment improves the assembly method of the panel 2 and the platform mounting frame 1 to reduce the overall weight and production cost of the lifting platform.

[0026] Specifically, the platform mounting frame 1 has mounting grooves 11 on both sides, and a plurality of strip-shaped reinforcing members 3 are provided at predetermined intervals along the front to rear side of the platform mounting frame 1, and the strip-shaped reinforcing members 3 are parallel to each other; both ends of the strip-shaped reinforcing members 3 are embedded in the mounting grooves 11 and are fixedly connected to the bottom of the mounting grooves 11; the plate surface 2 is provided on the platform mounting frame 1 and abuts against the surface of the strip-shaped reinforcing members 3;

[0027] The platform mounting frame 1 has baffles 4 vertically installed on both sides and the rear side, and the baffles 4 are perpendicular to the plate surface 2.

[0028] This utility model includes a platform mounting frame 1, a plate 2, and strip-shaped reinforcing members 3. Multiple strip-shaped reinforcing members 3 are arranged at predetermined intervals along the front to rear side of the platform mounting frame 1. Both ends of each strip-shaped reinforcing member 3 are embedded in the mounting groove 11. The plate 2 is disposed on the platform mounting frame 1 and abuts against the surface of the strip-shaped reinforcing members 3. By setting multiple strip-shaped reinforcing members 3 at the bottom of the plate 2, the assembly method replaces traditional welding, further avoiding the risk of thermal deformation, and is suitable for lifting scenarios with high precision requirements. It solves the problem of cold-plate welding in existing technologies, which results in excessive weight of the lifting platform and requires spot welding and spraying processes, effectively reducing production and transportation costs.

[0029] In some embodiments, the strip reinforcement 3 includes a first support wall 31 perpendicular to the plane direction of the plate surface 2, and the two sides of the first support wall 31 are bent in the same direction to form a second support wall 32, the bending direction of the second support wall 32 being parallel to the plate surface 2.

[0030] It should be noted that the first support wall 31 is perpendicular to the panel 2 and provides the main vertical support force. The second support wall 32 is formed by bending the two sides of the first support wall 31, and its direction is parallel to the panel 2, forming a laterally extended flange structure. Through geometric strengthening and mechanical optimization, the load-bearing capacity of the panel 2 is improved in a lightweight manner, which is particularly suitable for the balance between strength and weight required for aluminum structures.

[0031] Preferably, the number of strip reinforcement members is 5-8. This balances lightweight design, strength requirements, and manufacturing efficiency, meeting the dual standards of safety and portability for wheelchair lifts.

[0032] Preferably, the surface of the plate is provided with a plurality of perforations spaced at predetermined intervals.

[0033] Preferably, the platform mounting frame has a ramp on its front side. The ramp facilitates the sliding of wheelchairs onto the platform surface.

[0034] More preferably, the panel surface has at least one blocking protrusion from the front to the rear, and the axial direction of the blocking protrusion is parallel to the axial direction of the strip reinforcement. The blocking protrusion significantly improves the stability and safety of the wheelchair during lifting and lowering through a dual mechanism of physical limiting and friction enhancement.

[0035] More preferably, the cross-sectional area of ​​the blocking protrusion gradually decreases from the bottom to the top;

[0036] At least one of the aforementioned blocking protrusions is provided on the front edge of the plate surface, and pulleys are provided on both sides of the surface of the ramp. The arrangement of the blocking protrusions and the ramp facilitates the wheelchair to slide into the gap between the blocking protrusions, ensuring that the wheelchair is not likely to slide off the lifting platform during use, thus ensuring safety.

[0037] This utility model embodiment also provides a wheelchair lifting device, including the lifting platform as described above.

[0038] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
