Detailed Description

The invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and 2, a truck frame comprises an upper main board 1 and a plurality of axles 2 below the main board, wherein the front of the main board is provided with a connecting piece 11 connected to a truck head, the axles are arranged in front of and behind the lower side of the main board, the length direction of the axles is in the left-right direction, and wheels 3 are arranged on the axles; the method is characterized in that:

one or more lower vehicle plates 4 arranged in front and at the back are arranged under the main vehicle plate, a plurality of axles are arranged under the lower vehicle plates, and a plurality of axles are arranged under each lower vehicle plate;

the upper part of the lower plate and the lower part of the main plate are provided with a rotating shaft 41 and a rotating shaft seat 42 which are matched with each other, the rotating shaft seat is provided with a rotating shaft hole 43, the rotating shaft is arranged in the rotating shaft hole for connection, and a telescopic part 5 is connected between the main plate and the lower plate;

when the telescopic component is at one station, the lower part of the wheel below the lower vehicle plate is on a horizontal line; as shown in fig. 1;

when the telescopic component is at another station, the lower plate tilts forwards and backwards, and a connecting line below wheels below the lower plate and a horizontal line form an included angle alpha; as shown in fig. 2.

The arrangement of the invention is that when the frame is loaded, the telescopic parts can be adjusted to ensure that the lower parts of the wheels below the lower vehicle plate are all on the horizontal line, thus the lower wheels bear the weight and meet the requirement of heavy load, as shown in figure 1; when the frame is not loaded, the telescopic component can be adjusted, the upper surface of the lower board rotates by virtue of the rotating shaft 41 and the rotating shaft seat, the rotating direction is the direction of an arrow F in figures 1 and 2, so that wheels below the lower board are not on a horizontal line, as shown in figure 2, the lowest wheels are contacted with the ground, other wheels are not contacted with the ground, the number of wheels contacted with the ground below the lower board is reduced, the resistance is also reduced, the power of a vehicle is saved, and the effect of energy conservation can be realized.

The direction of arrow H in fig. 2 is the direction of extension (lifting) of the telescopic member;

the rotating shaft ensures that the lower plate can rotate, and the direction of an arrow F in the figures 1 and 2 is the rotating direction of the lower plate.

The main vehicle plate and the lower vehicle plate are both made of iron.

The telescopic component is a hydraulic cylinder, an oil cylinder, a manual spiral telescopic rod or a cushion block, and the expansion degree between the main vehicle plate and the lower vehicle plate can be adjusted.

The invention is more reasonable in arrangement.

A set of axles refers to a plurality of (typically two) sub-axles 21 from left to right, the axial center lines of which are on a straight line, and fig. 7 is a case where a set of axles includes two sub-axles.

Furthermore, protruding columns 6 are arranged on two sides of the lower vehicle plate, and two sides of the main vehicle plate are arranged in the protruding columns.

The invention can ensure that the load of the rotating shaft and the rotating shaft seat is larger when the frame is loaded and turns, reduces the left and right direction dislocation of the main frame plate on the lower frame plate and avoids the frame deformation caused by cost.

Further, as shown in fig. 3 and 4, the main board has a rotating shaft 71 thereon, the rotating shaft is mounted on the main board via a bearing 76, the center line of the rotating shaft is in the vertical direction, the rotating shaft is rotatable on the main board, and the vehicle seat further includes an expanding board 72 having a circular hole in the middle, the expanding board is placed on the rotating shaft, the rotating shaft passes through the circular hole of the expanding board, and both ends of the expanding board extend beyond the left and right sides of the main board.

The arrangement of the invention can realize that when the bridge 10 (such as a high-speed rail and a hook member of the bridge) carried by the frame is used, the lower surface of the front end of the bridge can be placed below the rotating shaft, and when a vehicle turns, the main board can conveniently rotate; the expansion plate is arranged in order to allow the side edge of the lower surface of the bridge to be carried to be received by the expansion plate under the condition that the girder is inclined, so that the bridge to be carried is prevented from directly contacting the upper surface of the main floor, as shown in figure 5.

The rotating shaft is provided with a nut 73 for mounting the expansion plate on the rotating shaft.

Further, it includes a circular pad 74 having a circular hole in the middle, which is mounted on the rotating shaft, below the expansion plate and above the main deck.

The invention is arranged in such a way that the resistance below the expansion plate is reduced when the expansion plate rotates.

Preferably, the pad is coated with a layer of yellow oil underneath, i.e., yellow oil layer 75 in the figure.

Further, the up-down direction of the rotating shaft hole is a long slotted hole in the length direction (namely, the height of the rotating shaft hole is larger than the width of the rotating shaft hole), and the rotating shaft is arranged in the rotating shaft hole and has frame amount in the up-down direction.

As shown in fig. 6, the invention has the advantages that the rotating shaft can move up and down when the vehicle frame turns, the rotating shaft hole is prevented from being pried by the rotating shaft, and the damage to the rotating shaft seat is reduced.

Further, the front frame structure comprises a front frame 8 arranged below the front face of the main frame plate, an axle and wheels arranged on the axle are arranged below the front frame, and the upper face of the front frame is connected below the main frame plate.

Furthermore, the vehicle frame further comprises a tail frame 9, wherein an axle and wheels mounted on the axle are arranged below the tail frame, and a connecting part 91 (such as a hook) connected to the main frame is arranged in front of the tail frame.

The tailstock is known in the industry as a gun carrier.

When the frame is used, as shown in fig. 5, the tail end of a bridge (10 in fig. 5 is a bridge for carrying) is supported on the tail frame, and the front end of the bridge is placed at the upper end of the rotating shaft, so that a longer bridge can be transported; the connecting member may be attached to the main frame when not carrying cargo.

Further, the tail frame is provided with a turntable 92.

The rotating discs are discs capable of rotating with each other, and the direction of an arrow D in fig. 5 is the rotating direction of the rotating discs.

The invention has the advantage of more convenient adjustment of the direction of the tail frame during turning.
