Description
Technical field
The utility model relates to a kind of novel semi-trailer bearing set.
Background technology
Superimposed trailer applies a kind of transportation means quite widely in modern transportation industry, superimposed trailer in motion its front end can be connected with tractor truck and to drag to be supported by it and to draw, the front end of superimposed trailer and tractor truck can be taken off when not travelling and hang, in order to support the front end of superimposed trailer after de-extension, the bottom of superimposed trailer front end is often provided with supporter of semi-trailer.Supporter of semi-trailer conventional is at present bi-directional variable speed, built-in feed screw nut and gear case, entirety is connected with the supporting plate on superimposed trailer by bolt, and need to strengthen gusset or inclined bearing reinforcement, realize promoting by crank and the inner driving device of bearing set during lifting, this supporter of semi-trailer complex structure, manufacturing cost is high, still being erected at that when not using, can not placement being packed up, still take up room.
Utility model content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, and low cost of manufacture, fitting operation is convenient, and save trouble and labor, increases work efficiency, a kind of novel semi-trailer bearing set do not taken up room.
The technical scheme that the utility model adopts for this reason is:
Comprise vehicle frame and supporting leg, described vehicle frame is welded with permanent seat, a through hole is provided with in described permanent seat, one bearing is installed in described through hole, one S. A. is installed in described bearing, the outer end of described S. A. is fixedly connected with supporting leg upper end, described vehicle frame is provided with driving cylinder, rear end and the vehicle frame of described driving cylinder are articulated and connected, the piston rod end of cylinder is driven to be articulated and connected with supporting midleg, the upper end of described supporting leg is also provided with knock hole I, described vehicle frame is provided with the knock hole II matched with knock hole I, described knock hole I is connected by alignment pin with knock hole II.
Further, the knock hole I on described supporting leg is positioned at the top of S. A..
Further, the outer end of described alignment pin is connected with chain, and the other end of described chain is fixedly mounted on vehicle frame.
Further, described driving cylinder is connected with control cock.
Further, the lower end of described supporting leg is provided with step disk, and the lower end of described step disk and supporting leg is articulated and connected.
The utility model has the advantages that:
The utility model structure is simple, low cost of manufacture, installs and convenient to operation, save trouble and labor, thus improves work efficiency, can be packed up, conserve space when not using.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 be vehicle frame, 2 are supporting legs, 3 to be S. A.s, 4 be that to drive cylinder, 5 to be alignment pin, 6 are chains, 7 is step disks.
Detailed description of the invention
A kind of novel semi-trailer bearing set, comprise vehicle frame 1 and supporting leg 2, described vehicle frame 1 is welded with permanent seat, a through hole is provided with in described permanent seat, one bearing is installed in described through hole, one S. A. 3 is installed in described bearing, the outer end of described S. A. 3 is fixedly connected with supporting leg 2 upper end, described vehicle frame 1 is provided with and drives cylinder 4, rear end and the vehicle frame 1 of described driving cylinder 4 are articulated and connected, the piston rod end of cylinder 4 and the middle part of supporting leg 2 is driven to be articulated and connected, the upper end of described supporting leg 2 is also provided with knock hole I, described vehicle frame 1 is provided with the knock hole II matched with knock hole I, described knock hole I is connected by alignment pin 5 with knock hole II, knock hole I on described supporting leg 2 is positioned at the top of S. A. 3, the outer end of described alignment pin 5 is connected with chain 6, and the other end of described chain 6 is fixedly mounted on vehicle frame 1, described driving cylinder 4 is connected with control cock, the lower end of described supporting leg 2 is provided with step disk 7, and described step disk 7 is articulated and connected with the lower end of supporting leg 2.
When needs bearing set supports, drive cylinder 4 to be pushed by supporting leg 2, then by alignment pin 5, the knock hole II on the knock hole I of supporting leg 2 upper end and vehicle frame 1 is coupled together, thus ensure that supporting leg 2 can not rotate; When not needing bearing set, alignment pin 5 being extracted from knock hole I and knock hole II, driving cylinder 4 to be packed up by supporting leg 2.
