Description
Technical field
The present invention relates to a kind of jacking system, refer to especially wheel lifter after a kind of platform truck.
Background technology
At present, wheel lifter after the existing platform truck in the whole world, structure is larger, has no idea to prevent in long and narrow space, and complex structure, so that complicated operation, be unfavorable for using, and assembling is inconvenient, is unfavorable for transporting.
Summary of the invention
The object of this invention is to provide wheel lifter after a kind of platform truck, from following 2 principles, solve this defect: larger in order to overcome existing platform truck trailing wheel lifting device structure, have no idea to prevent in long and narrow space, complex structure, so that complicated operation, be unfavorable for using, assembling is inconvenient, is unfavorable for transporting.
In order to achieve the above object, the invention provides following technical scheme:
After a wheel lifter, comprising: trailing wheel, connecting panel, adjustment rack, oil cylinder, A point, B point, C point and D point.Connecting panel connects two trailing wheels; Two trailing wheels are connected by connecting panel; B point is located in the middle of connecting panel; The upper end that connecting panel covers the wheel of trailing wheel is provided with A point; A point is located at adjustment rack upper end; Adjustment rack is located at connecting panel one side; Adjustment rack is connected by C point with oil cylinder; C point connects adjustment rack and oil cylinder; Oil cylinder one end is provided with D point; Whole jacking system is located in vehicle frame.
In invention, two trailing wheels and its connecting panel adopt bearing pin hinged, and adopt nut that two trailing wheels are spacing, prevent that it from swinging; On adjustment rack, as above figure is marked with A, B, C 3 points.A point and vehicle frame are hinged by bearing pin, and install and adjust pad, with this, adjust the gap between whole trailing wheel and vehicle frame; B point and connecting panel are hinged by bearing pin, and two trailing wheels can rotate around it, and with this, guarantee the stationarity of car load; The piston rod of C point and oil cylinder is hinged by bearing pin, with this, obtains the lifting that power is realized vehicle frame; The steel cylinder of oil cylinder is hinged on vehicle frame by bearing pin, and piston rod is hinged on adjustment rack by bearing pin.
The invention has the beneficial effects as follows: save space, particularly, in long and narrow spatial dimension, the performance of the advantage of this structure obviously; Mode is simple, and the lifting of vehicle frame only need be controlled by the flexible of oil cylinder, there is no unnecessary structure; Easy to assembly, the dual wheel assembly installation of can packing after car load, with being connected of vehicle frame only need be hinged by two bearing pins; Adopt this kind of structure, car load height is adjustable.When car load need travel, car load height raises, and improves the crossing ability of car load.When car load needs operation transmission, car load height reduces, and meets the transmission requirement of goods; Cost, the optimization by structure makes to manufacture and the cost such as assembling is controlled and reduces.
Accompanying drawing explanation
Fig. 1 is that after a kind of platform truck, the oil cylinder of wheel lifter stretches out structure graph.
Fig. 2 is that the oil cylinder of wheel lifter after a kind of platform truck reclaims structure graph.
Fig. 3 is the structural perspective of wheel lifter after a kind of platform truck.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As shown in Figure 1, Figure 2, Fig. 3 and shown in, wheel lifter after a kind of platform truck, comprising: trailing wheel 1, connecting panel 2, adjustment rack 3, oil cylinder 4, A point 6, B point 7, C point 8 and D point 9.Connecting panel 2 connects two trailing wheels 1; Two trailing wheels 1 are connected by connecting panel 2; B point 7 is located in the middle of connecting panel 2; The upper end that connecting panel 2 covers the wheel of trailing wheel 7 is provided with A point 6; A point 6 is located at adjustment rack 3 upper ends; Adjustment rack 3 is located at connecting panel 2 one sides; Adjustment rack 3 is connected by C point 8 with oil cylinder 4; C point 8 connects adjustment rack 3 and oil cylinder 4; Oil cylinder 4 one end are provided with D point 9; Whole jacking system is located in vehicle frame 5.
After above-mentioned a kind of platform truck, the principle of work of wheel lifter is: the lifting of vehicle frame is stretched out and gets control back by oil cylinder, meets the requirement that goods docking transmission and car load travel; A point 6, D point 9 all utilize bearing pin to be hinged on vehicle frame, and B point 7 utilizes bearing pin that rear two-wheel and adjustment rack 3 is hinged, and C point 8 utilizes bearing pin that adjustment rack 3 is hinged with the piston rod of oil cylinder 4.When the piston rod of oil cylinder 4 stretches out when regaining, its C point 8 application forces are under the support at A point 6, form and B point 7 is similar to the mode of motion of seesaw for the up-and-down movement state of relation; When needs vehicle frame declines, the piston rod of oil cylinder 4 stretches out, and under the effect of oil cylinder 4, rear two-wheel 1 integral body will be around A point 6 upward movements, ground relatively, and it is that vehicle frame declines that vehicle frame moves downward under the induced effect of oil cylinder 4; When needs vehicle frame rises, the piston rod of oil cylinder 4 is regained, and under the effect of oil cylinder 4, rear two-wheel 1 integral body will move downward around A point 6, ground relatively, and vehicle frame upward movement under the induced effect of oil cylinder 4 is that vehicle frame 5 rises.
According to above-mentioned principle of work: in invention, two trailing wheels 1 adopt bearing pins hinged with its connecting panel 2, and adopt nut that two trailing wheels are spacing, prevent that it from swinging; On adjustment rack 3, be marked with A, B, C 3 points.A point 6 is hinged by bearing pin with vehicle frame 5, and installs and adjust pad, with this, adjusts the gap between whole trailing wheel 1 and vehicle frame 5; B point 7 is hinged by bearing pin with connecting panel 2, and two trailing wheels 1 can rotate around it, and with this, guarantee the stationarity of car load; C point 8 is hinged by bearing pin with the piston rod of oil cylinder 4, with this, obtains the lifting that power is realized vehicle frame 5; The steel cylinder of oil cylinder 4 is hinged on vehicle frame by bearing pin, and piston rod is hinged on adjustment rack 3 by bearing pin.
The invention has the beneficial effects as follows: save space, particularly, in long and narrow spatial dimension, the performance of the advantage of this structure obviously; Mode is simple, and the lifting of vehicle frame only need be controlled by the flexible of oil cylinder, there is no unnecessary structure; Easy to assembly, the dual wheel assembly installation of can packing after car load, with being connected of vehicle frame only need be hinged by two bearing pins; Adopt this kind of structure, car load height is adjustable.When car load need travel, car load height raises, and improves the crossing ability of car load.When car load needs operation transmission, car load height reduces, and meets the transmission requirement of goods; Cost, the optimization by structure makes to manufacture and the cost such as assembling is controlled and reduces.
