For the direction word appearing in the utility model, it is to better explain the characteristics of features and the relationship between features, it should be understood that when the display direction of the utility model changes, the direction of the characteristics of features and the relationship between features also changes accordingly, therefore the direction word does not constitute the absolute limitation of the characteristics of features and the relationship between features in space, and only plays a relative limiting role.

[0025] The utility model provides a kind of lifting machine of two-stage top plate, as shown in Figures 1 to 5 It includes base 1, top plate 2 and upper guide plate 3;Top plate 2 is set in base 1 in a lifting manner, and existing technology such as scissor structure cooperation hydraulic is arranged between top plate 2 and base 1 to realize the lifting of top plate 2;The both ends of base 1 are connected with upper guide plate 3;Upper guide plate 3 includes first inclined guide plate 31, connecting flat guide plate 32 and second inclined guide plate 33, one end of connecting flat guide plate 32 is connected with first inclined guide plate 31, and the other end is connected with second inclined guide plate 33;The end of second inclined guide plate 33 away from connecting flat guide plate 32 is connected to base 1;It is easy to understand that upper guide plate 3 will not be lifted with the lifting of top plate.

[0026] The ground clearance of connecting flat guide plate 32 is 50-70mm, further preferably, the ground clearance of connecting flat guide plate 32 is 60mm;The ground clearance of top plate 2 is 120-140mm, further preferably, the ground clearance of top plate 2 is 130mm;The ground clearance difference between connecting flat guide plate 32 and top plate 2 is 70mm. In the direction of the length of the car driving into upper guide plate 3, the length L of upper guide plate 3 is 800-1600mm, further preferably, the length L of upper guide plate 3 is 1200mm.

[0027] Based on the above structure, the first inclined guide plate 31 and the second inclined guide plate 33 make the connecting flat guide plate 32 and the top plate 2 respectively at different height platforms, which disperses the originally large height difference in two platforms, thereby reducing the height change of each platform and reducing the risk of chassis bumping; at the same time, the connecting flat guide plate 32 can serve as a transition, so that the chassis of the lower vehicle can be more easily transitioned to the top plate 2, and the reasonable ground clearance and ground clearance difference design will not cause the vehicle to bump the chassis when getting on the vehicle due to the too large height difference. The length and height set are the best choices after considering the production cost and use effect.

[0028] In the embodiment, the end of the second inclined guide plate 33 away from the connecting flat guide plate 32 is fixedly connected with the base 1 by the screw 4, of course, the second inclined guide plate 33 can also be fixedly connected by bolts, rivets, latches and the like, so that it is easier to disassemble and replace during maintenance, greatly reducing the maintenance cost and time.

[0029] In the embodiment, the base 1 is provided with a connecting lug 11, and the second inclined guide plate 33 is provided with a matching lug 331, both the connecting lug 11 and the matching lug 331 are provided with a screw hole 5, and the screw 4 is threadedly connected with the screw holes 5 of the connecting lug 11 and the matching lug 331, so as to fixedly connect the second inclined guide plate 33 with the base 1. Through the close cooperation of the connecting lug 11 and the matching lug 331, stable connection can be achieved, and the stability of the entire connection is significantly enhanced.

[0030] In the embodiment, the base 1 is further provided with a connecting bottom plate 12, and the second inclined guide plate 33 is provided with a connecting gap 332, and the connecting bottom plate 12 can be placed in the connecting gap 332, so that the overall structure is more compact, and at the same time, the contact area between the second inclined guide plate 33 and the base 1 can be increased, the connection between the second inclined guide plate 33 and the base 1 is more closely, the connection strength is enhanced, and the stability and reliability of the entire structure are improved.

[0031] In the embodiment, the second inclined guide plate 33 is further provided with a receiving gap 333, when the second inclined guide plate 33 is connected with the base 1 and the top plate 2 is at the lowest position, the receiving gap 333 can accommodate the edge of the top plate 2 and the height of the receiving gap 333 matches the height of the top plate 2. The arrangement of the receiving gap 333 makes the gap between the second inclined guide plate 33 and the top plate 2 smaller, and at the same time, when the top plate 2 is at the lowest position, the top plate 2 can also press the receiving gap 333, so that the connection between the second inclined guide plate 33 and the base 1 is more closely.

[0032] It is easy to understand that when the car is driven onto the top plate 2 by means of the secondary inclined guide plate 33, most of the weight of the car will be pressed on the secondary inclined guide plate 33, and if the secondary inclined guide plate 33 is not firmly connected with the top plate 2, the secondary inclined guide plate 33 will jump greatly, cause great noise, affect the service life of the lifting machine, and make the secondary inclined guide plate 33 and the top plate 2 more likely to be misaligned, all of which are unfavorable factors. However, in the embodiment, the connecting gap 332 and the accommodating gap 333 of the secondary inclined guide plate 33 can increase the contact surface between the secondary inclined guide plate 33 and the connecting bottom plate 12 and the top plate 2, so that the secondary inclined guide plate 33 is clamped and the relative position relationship between the secondary inclined guide plate 33 and the top plate 2 is relatively stable, thereby reducing the above-mentioned unfavorable factors and achieving better use effect.

[0033] In the embodiment, the angle between the primary inclined guide plate 31 and the horizontal direction forms an angle ∠1 of 15-20°, and further preferably, the angle between the primary inclined guide plate 31 and the horizontal direction forms an angle ∠1 of 18°; the angle between the secondary inclined guide plate 33 and the horizontal direction forms an angle ∠2 of 20-25°, and further preferably, the angle between the secondary inclined guide plate 33 and the horizontal direction forms an angle ∠2 of 22°. Through the above structural design, when the car is loaded, the slope of the primary inclined guide plate 31 is small, so the car chassis will not be bumped at this time, and when the front wheels of the vehicle reach the top plate 2, the rear wheels have reached the height of the connecting flat guide plate 32, and the slope of the secondary inclined guide plate 33 is large, so the car chassis will not be bumped.

[0034] In summary, the lifting machine with the two-stage loading plate can solve the problem that the top plate of the lifting machine in the prior art bumps the chassis of a low car.

[0035] In the case of no conflict, the above embodiments and features in the embodiments can be combined with each other.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
