Description

Technical Field

[0001] This utility model relates to the field of vehicle maintenance technology, and in particular to a column-type lifting platform. Background Technology

[0002] In the manufacturing, assembly, and repair of heavy vehicles, such as off-road vehicles, large buses, and heavy trucks, safe, efficient, and stable lifting equipment is an indispensable core component in chassis installation, component assembly, and comprehensive overhaul operations. Currently, the industry commonly uses two main lifting methods: direct tire lifting or using a four-post or multi-post lift to raise the chassis. These methods aim to securely lift the massive vehicle body off the ground, creating the necessary and safe working space for technicians beneath the chassis.

[0003] However, as revealed in patent document CN118458630A, existing lifting platforms have gradually revealed two key technical defects during long-term, high-intensity use, which restrict their efficiency and service life.

[0004] First, there's the structural issue of "platform sagging." Heavy vehicles are extremely heavy. When the lifting platform, especially its inner beams or support structures, repeatedly bears such enormous concentrated loads, the metal materials undergo microscopic plastic deformation due to continuous stress. Over time, this deformation accumulates and manifests as a visible, inward and downward "platform sagging." This not only affects the platform's flatness, leading to a risk of tilting after the vehicle is lifted, but more importantly, it disrupts the mechanical balance of the entire lifting system, creating potential safety hazards. In the long run, this structural fatigue accelerates equipment aging, increases maintenance costs, and may even shorten the equipment's service life.

[0005] Secondly, existing platforms suffer from a fundamental flaw: insufficient adaptability. The market offers a wide variety of heavy-duty vehicle models, with significant differences in wheelbase, track width, and even chassis structure. Traditional lifting platforms often have fixed lifting widths or relative support points. This leads to an awkward situation: a lifting machine might perfectly fit a standard truck model, but it falls short for buses with wider track widths or dedicated off-road vehicles with shorter wheelbases, making effective and safe lifting operations impossible. This limitation of "dedicated machines for specific purposes" severely reduces equipment utilization and workshop operational flexibility, forcing repair shops or production lines to equip themselves with multiple specifications of lifting equipment, resulting in resource waste and inefficient use of space.

[0006] In view of this, it is necessary to develop a column-type lifting platform to overcome the above-mentioned defects. Summary of the Invention

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to disclose a column-type lifting platform.

[0008] The purpose of this invention is to provide a column-type lifting platform.

[0009] To achieve the above-mentioned objectives, this utility model provides a column-type lifting platform, which consists of two parallel platforms forming a vehicle lifting platform;

[0010] The vehicle lifting platform is equipped with column lifting assemblies at its four corners, and each column lifting assembly includes a column and a lifting slide.

[0011] The width of the lifting slide is greater than the width of the platform. A limiting step is provided at the end of the lifting slide. The lifting slide is provided with at least one set screw. The set screw is located close to the inner edge of the platform and abuts against the bottom wall of the platform.

[0012] When unloaded, the inner sides of the two platforms tilt upwards by 2°-3°.

[0013] Preferably, a first groove and a second groove are respectively provided on both sides of the lifting slide;

[0014] The set screw located in the first groove passes through the top wall of the lifting slide and abuts against the bottom wall of the platform.

[0015] Preferably, the set screw located in the second groove passes through the top wall of the lifting slide and abuts against the bottom wall of the platform.

[0016] Preferably, the top wall of the lifting slide is provided with a first waist hole and a second waist hole, the first waist hole facing the first groove and the second waist hole facing the second groove;

[0017] The bottom wall of the platform is locked to the first waist hole and the second waist hole.

[0018] Preferably, the lengths of both the first waist hole and the second waist hole are 10cm-15cm.

[0019] Preferably, the two platforms arranged in parallel are spaced apart by adjusting the distance between them through the first waist hole and the second waist hole.

[0020] Preferably, the column lifting assembly is disposed in the middle of the platform.

[0021] Preferably, the distance between the set screw and the inner edge of the platform is 15cm-20cm.

[0022] Preferably, each of the column lifting components is raised and lowered synchronously.

[0023] Preferably, the width of the lifting slide is 80cm-90cm.

[0024] Compared with the prior art, the technical effects of this utility model are as follows:

[0025] This utility model features two symmetrically arranged parallel platforms that lift the tires on both sides of the vehicle. By tightening the jack screws and slightly lifting the bottom wall near the inner edge of the platform, the inner side of the platform tilts up slightly by 2°-3° when unloaded to compensate for structural deformation under load. This ensures that the platform is in or close to a horizontal state when the heavy vehicle is stopped, effectively preventing sagging. The platforms are locked at different positions of the first and second waist holes, which can reduce or increase the distance between the two platforms by 20cm-30cm, greatly increasing adaptability.

It should be noted that these embodiments do not limit the present utility model. Any equivalent change or substitution in function, method or structure made by those skilled in the art according to these embodiments shall fall within the protection scope of the present utility model.

[0033] Example 1

[0034] Referring to Figures 1 to 4 , this embodiment discloses a specific embodiment of a column-type lifting platform.

[0035] For the column-type lifting platform, referring to Figures 1 to 4 , the vehicle lifting platform consists of two platforms arranged in parallel, and with reference to Figure 1 , the two platforms are respectively a first platform (11) and a second platform (12); column lifting assemblies (2) are respectively arranged at four corners of the vehicle lifting platform, the column lifting assembly (2) includes a column (21) and lifting sliding tables (22), two lifting sliding tables (22) synchronously lift the bottom walls (14) at both ends of the first platform (11), two lifting sliding tables (22) synchronously lift the bottom walls (14) at both ends of the second platform (12), and all the column lifting assemblies (2) lift and lower synchronously, that is, all the lifting sliding tables (22) lift and lower synchronously, so that the first platform (11) and the second platform (12) lift and lower synchronously; the width W1 of the lifting sliding table (22) is greater than the width W2 of the platform (1), the end of the lifting sliding table (22) is provided with a limit step (221), the lifting sliding table (22) is provided with at least one jackscrew (222), the position of the jackscrew (222) is close to the inner edge (13) of the platform (1), the jackscrew (222) abuts against the bottom wall (14) of the platform (1), the distance L between the jackscrew (222) and the inner edge of the platform (1) is 15 cm-20 cm; the width W1 of the lifting sliding table (22) is 80 cm-90 cm, the limit step (221) limits the adjustable range of the first platform (11) or the second platform (12), prevents the first platform (11) or the second platform (12) from slipping off, and ensures lifting safety; when no load, the inner sides of the two platforms (1) tilt up by 2°-3°, that is, the inner sides of the first platform (11) and the second platform (12) both tilt up by 2°-3°.

[0036] Specifically, referring to Figures 1 to 4The lifting slide 22 has a first groove 223 and a second groove 224 respectively on both sides. The first groove 223 and the second groove 224 are symmetrically arranged. On the one hand, the first groove 223 and the second groove 224 can reduce the weight of the lifting slide 22. The first groove 223 and the second groove 224 also provide installation space for the set screw 222. The set screw 222 located in the first groove 223 passes through the top wall 225 of the lifting slide 22 and abuts against the bottom wall 14 of the platform 1. The set screw 222 located in the second groove 224 passes through the top wall 225 of the lifting slide 22 and abuts against the bottom wall 14 of the platform 1. For the first platform 11, the first level can be adjusted. The set screws 222 at both ends of the first platform 11 slightly raise the inner side of the first platform 11 by 2°-3°, so that when a heavy vehicle stops on the first platform 11, the first platform 11 remains horizontal and does not sag. Similarly, for the second platform 12, the set screws 222 at both ends of the second platform 12 can be adjusted to slightly raise the inner side of the second platform 12 by 2°-3°, so that when a heavy vehicle stops on the second platform 12, the second platform 12 remains horizontal and does not sag. After a period of use, if the first platform 11 and the second platform 12 have been flattened, the set screws 222 can be adjusted to keep the first platform 11 and the second platform 12 slightly raised by 2°-3°.

[0037] See Figures 1 to 4 To improve the adaptability of the first platform 11 and the second platform 12, the top wall of the lifting slide 22 is provided with a first waist hole 226 and a second waist hole 227. The first waist hole 226 and the second waist hole 227 are symmetrically arranged, and two of each are provided. The first waist hole 226 faces the first groove 223, and the second waist hole 227 faces the second groove 224. The bottom wall 14 of the platform 1 is locked to the first waist hole 226 and the second waist hole 227. The length of the first waist hole 226 and the second waist hole 227 is 10cm-15cm. For vehicles of different widths, the two parallel platforms 1 can adjust the distance between them through the first waist hole 226 and the second waist hole 227. By locking the platform 1 to different positions of the first waist hole 226 and the second waist hole 227, the distance between the first platform 11 and the second platform 12 can be reduced or increased by 20cm-30cm, greatly increasing adaptability.

[0038] To accommodate extra-long heavy vehicles, the platform 1 is equipped with column lifting components 2 in the middle. In this configuration, the first platform 11 is lifted by three column lifting components 2, and the second platform 12 is also lifted by three column lifting components 2. Each column lifting component 2 has the same structure, including a set screw 222, a first waist hole 226, and a second waist hole 227. By screwing on each set screw 222 and slightly lifting the bottom wall near the inner edge of the platform 1, the platform 1 is slightly tilted up by 2°-3°, ensuring that the platform 1 remains horizontal and does not sag when the heavy vehicle stops on it. After a period of use, if the platform 1 has been flattened, the set screws can be adjusted to maintain a slight tilt of 2°-3°. The platform 1 is locked at different positions of the first waist hole 226 and the second waist hole 227, allowing the distance between the two platforms 1 to be reduced or increased by 20cm-30cm, significantly increasing adaptability.
