Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
fig. 2 is a schematic view of the structure of the joint between the middle connecting rod and the cross rod of the present invention.
In the figure: 1 chassis, 2 supports, 3 pneumatic cylinders, 4 horizontal poles, 5 connecting rods, 6 trompils, 7 bracing pieces, 8 supporting seats, 9 linear bearings, 10 dogs.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-2, an automatic lifting support device for an electric trailer comprises an underframe 1, a support 2 fixedly connected to the bottom end of the underframe 1, and a hydraulic cylinder 3 horizontally mounted on the support 2, which is prior art and is not described herein again.
The piston rod of the hydraulic cylinder 3 extends into the support 2 and is connected with a pressure-equalizing supporting mechanism, and the pressure-equalizing supporting mechanism is composed of a cross rod 4, a connecting rod 5 and a supporting rod 7.
The horizontal pole 4 is connected with the piston rod fixed connection of pneumatic cylinder 3, and the quantity of connecting rod 5 and bracing piece 7 is a plurality ofly, and connecting rod 5 rotates with bracing piece 7 to be connected, and the one end that bracing piece 7 was kept away from to connecting rod 5 rotates with horizontal pole 4 to be connected.
Referring to fig. 2, in the present embodiment, the manner of the rotational connection is as follows: the two ends of the connecting rod 5 are fixedly connected with pin shafts, and the connecting rod 5 is rotatably connected with the cross rod 4 and the supporting rod 7 through the pin shafts.
The bottom of support 2 is seted up the trompil 6 that quantity equals with bracing piece 7, and bracing piece 7 passes trompil 6. The arrangement of the open hole 6 plays a role in limiting, so that the support rod 7 can only move up and down linearly.
The end part of the supporting rod 7 penetrating through the opening 6 is fixedly connected with a supporting seat 8, and the supporting seat 8 is perpendicular to the supporting rod 7. The arrangement of the supporting seat 8 can increase the contact area with the ground.
The one end clearance that pneumatic cylinder 3 was kept away from to horizontal pole 4 passes support 2 and fixedly connected with dog 10, and the effect of anticreep has been played in setting up of dog 10, avoids horizontal pole 4 to deviate from support 2.
The bracket 2 is provided with a linear bearing 9, and the cross rod 4 is connected with the linear bearing 9 in a sliding way. The linear bearing 9 plays a role in supporting and fixing, so that the cross rod 4 can only slide linearly, and the mechanical movement efficiency is improved.
The working principle is as follows:
when needs support, 3 motions of drive pneumatic cylinder (for the shrink motion in this embodiment), drive 4 endwise slip of horizontal pole after pneumatic cylinder 3 extends, 4 slides back drive a plurality of connecting rods 5 from the tilt state to the vertical state motion of horizontal pole, when connecting rod 5 changes from the tilt to the vertical state, drive the bracing piece 7 under it and stretch out to the outside, bracing piece 7 fixedly connected with supporting seat 8, accomplish concertina movement until fixing base 8 and ground contact, because the setting of a plurality of bracing pieces 7 and supporting seat 8 has played the effect of voltage-sharing.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
