Description

Technical Field

[0001] This utility model relates to the field of lifting platform technology, specifically a lifting platform. Background Technology

[0002] On lifting platforms, there is often a problem of uneven support. This is because, in general, during the lifting process, the lifting rod slides and moves, which causes the lifting rod on one side of the lifting platform to move inward, resulting in unstable support of the platform.

[0003] To address the aforementioned technical problems, Chinese Patent CN222907435U describes a lifting platform. The first lower support rod is pivotally connected at one end to one end of the chassis, and at the other end to the lower end of the first connecting rod; the upper end of the first connecting rod is pivotally connected to the first upper support rod; one end of the first upper support rod is pivotally connected to the other end of the bearing platform, and at the other end to the upper end of the second connecting rod; the lower end of the second connecting rod is pivotally connected to the first lower support rod; one end of the second lower support rod is pivotally connected to the other end of the chassis, and at the other end is coaxially pivotally connected to the pivot shaft connecting the second connecting rod and the first upper support rod; one end of the second upper support rod is pivotally connected to the other end of the bearing platform, and at the other end is coaxially pivotally connected to the pivot shaft connecting the first connecting rod and the first lower support rod. This invention achieves lifting, offers high safety, and has a long service life. See the appendix of this patent for details. Figure 1 With appendix Figure 2 It is evident that while this patent does solve the support problem, certain technical issues remain. Firstly, the actual support problem needs to be understood: the lifting rod on one side slides during lifting, resulting in insufficient support on one side of the platform. Therefore, it is necessary to have another set of support rods replace the lifting rod during movement. Although this patent solves the support problem, the structure is overly complex, and the first upper support rod in this patent experiences significant stress, which can cause deformation over time. Furthermore, the platform's load-bearing capacity is insufficient, making it prone to bending and deformation when carrying heavy loads.

[0004] Therefore, in order to solve the above-mentioned existing technical problems, achieve platform support balance in simple structural contact, and increase the stability of the platform, a lifting platform is proposed to overcome the above-mentioned existing technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a lifting platform that solves the problems of complex structure in balance support and poor stability of existing lifting platforms.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lifting platform, including a chassis, on which a lifting structure is mounted. A stable platform is mounted on the upper end of the lifting structure via a connecting structure. An auxiliary support structure is also mounted on the lifting structure. This auxiliary support structure includes a connecting structure one and a support rod. The connecting structure one includes a guide rail two, a limiting block two, and a movable seat two. The guide rail two is mounted on the lower end face of the stable platform. Limiting blocks two are mounted on the left and right ends of the guide rail two. A slider is movable on the surface of the guide rail two, and a movable seat two is mounted on the slider. The platform is connected to the support rod, and the other end of the support rod is movably installed on the lifting structure. The stable platform includes a platform frame, an upper frame, a lower frame, a base plate, bolts, a top plate, and a mounting plate. The guide rail two and the limit block two are installed on the lower end face of the base plate. The platform frame is installed on the upper end face of the base plate. The upper frame and the lower frame are installed on the inner side of the platform frame. The top plate is installed on the upper end of the platform frame. Multiple sets of openings are opened on the surface of the top plate. The openings penetrate the base plate. Bolts are inserted into the openings, and multiple sets of nuts are provided on the surface of the bolts. Nuts are provided on the upper end face of the upper frame, the lower end face of the upper frame, and the lower end face of the base plate.

[0007] Further, the lifting structure includes a second connecting structure and a lifting assembly. The lifting assembly is movably connected to the second connecting structure. The lifting assembly includes a scissor lift rod and a hydraulic cylinder. Two sets of scissor lift rods intersect to form a group. An opening is provided at the intersection, and a pin is inserted into the opening. The front and rear ends of the pin are provided with circular plates. A hydraulic cylinder is installed on the inner surface of two adjacent sets of pins.

[0008] Furthermore, a transverse connecting shaft is provided at the intersection of the outer ends of the two sets of scissor lift rods, and the surface of the transverse connecting shaft is movably connected to the support rod.

[0009] As a preferred technical solution, the support rod on the left side is located inward, the support rod on the right side is located outward, and the left support rod is located between the outer support rods.

[0010] Furthermore, the second connection structure includes a guide rail, a limiting block, a movable seat, a guide rail, a limiting block, and a movable seat; the guide rail and the limiting block are both installed on the upper surface of the chassis, and a slider is movably connected to the surface of the guide rail. The movable seat is connected to the slider, and the movable seat is movably connected to the scissor lift rod.

[0011] Both the guide rail 2 and the limit block 2 are installed at the lower end of the base plate. A slider is movable on the surface of the guide rail 2. The slider is connected to the movable seat 2, which is movably connected to the scissor lift rod.

[0012] Compared with the prior art, the present invention provides a lifting platform with the following advantages:

[0013] 1. This lifting platform uses two sets of support rods, see diagram. Figure 4As can be seen, the two sets of support rods are connected to the transverse connecting shaft. Through the connection structure of guide rail 2, slider, and moving seat, when the scissor lift is raised or lowered, its corresponding support rod can move outward, thereby enabling it to effectively support the stable platform. Thus, through the above-mentioned support method, the stable platform can be effectively supported on a simple structural basis.

[0014] 2. This lifting platform is stabilized through the platform frame, upper frame, lower frame, base plate, bolts, top plate, and mounting plate. The upper and lower frames, as well as the bolts and nuts, work together to significantly improve the support capacity of the top plate, thus enhancing the stability of the platform.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-6 This utility model provides the following technical solution: A lifting platform includes a chassis 1, on which a lifting structure is installed. A stable platform 10 is installed on the upper end of the lifting structure via a connecting structure. An auxiliary support structure is also installed on the lifting structure. This auxiliary support structure includes a connecting structure one and a support rod 11. The connecting structure one includes a guide rail two 7, a limiting block two 8, and a movable seat two 9. The guide rail two 7 is installed on the lower end face of the stable platform 10. Limiting blocks two 8 are installed on the left and right ends of the guide rail two 7. A slider is movably mounted on the surface of the guide rail two 7, and a movable seat two 9 is mounted on the slider. The movable seat two 9 is movably connected to the support rod 11. The other end of the support rod 11 is movably mounted on the lifting structure. The stable platform 10 includes a platform frame. 1001, upper frame 1002, lower frame 1003, base plate 1004, bolt 1005, top plate 1006, mounting plate 1007; guide rail 2 7 and limit block 2 8 are installed on the lower end face of the base plate 1004. The upper end face of the base plate 1004 is equipped with a platform frame 1001. The inner side of the platform frame 1001 is equipped with the upper frame 1002 and the lower frame 1003. The upper end of the platform frame 1001 is equipped with a top plate 1006. The surface of the top plate 1006 has multiple sets of openings that penetrate the base plate 1004. Bolts 1005 are inserted into the openings, and the surface of the bolts 1005 is provided with multiple sets of nuts, including nuts located on the upper end and lower end face of the upper frame 1002 and the lower end face of the base plate 1004.

[0025] In this implementation plan, the specific working principle is as follows: when the platform lifts the stable platform 10 via the lifting structure, the support rod 11 (see...) Figure 4 As can be seen, it can effectively support both sides of the stable platform structure 10. Through guide rail 2 7, slider, and movable seat 2 9, one end of the support rod 11 is connected to the movable seat 2 9, and the other end is connected to the lifting structure. This facilitates the movement of the support rod 11 when the lifting structure rises. The rising lifting structure causes the support rod 11 to move outwards from the stable platform 11, and the falling lifting structure causes the support rod 11 to move inwards. It should be noted that, to improve safety, the scissor lift rod 5 should not be at a large angle during lifting. This also avoids the possibility of the support rod 11 exerting force on the scissor lift rod 5. Furthermore, through the action of the upper frame 1002, lower frame 1003, bolts 1005, and nuts (participating in...), the platform can effectively support both sides of the stable platform structure 10. Figure 5 As can be seen, the connection stability between the top plate 1006 and the bottom plate 1004 is significantly improved, thus enhancing the support capacity of the stable platform 10.

[0026] Based on the above, please refer to the details of the lifting structure. Figure 1 , Figure 3 and Figure 4As can be seen, the lifting structure includes a second connecting structure and a lifting assembly. The lifting assembly is movably connected to the second connecting structure. The lifting assembly includes a scissor lift rod 5 and a hydraulic cylinder 6. Two sets of scissor lift rods 5 are intersected as a group, and an opening is provided at the intersection. A pin is inserted into the opening. The front and rear ends of the pin are provided with circular plates. A hydraulic cylinder 6 is installed on the inner surface of two adjacent sets of pins. The hydraulic cylinder 6 mainly drives the scissor lift rod 5 to move up and down.
