Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, an embodiment of the present invention provides a side-tipping carriage capable of being opened from two sides, which includes a bottom plate 1, side plates 2 disposed on two sides of the bottom plate 1, and end walls 3 disposed on two ends of the bottom plate. The bottom edges of the side plates 2 on the two sides are rotatably connected with the corresponding side edges of the bottom plate 1 and can be opened and closed, and the side plates are driven by a side plate driving part arranged on the end wall 3. In this embodiment, the side plate driving portion is a first hydraulic cylinder 4, two first hydraulic cylinders 4 are disposed on each end wall 3, and the end portions of the piston rods of the first hydraulic cylinders 4 are hinged to the end portions of the corresponding side plates 2, so that both ends of one side plate 2 are driven by one first hydraulic cylinder 4, and of course, the side plate driving portion may be disposed at one end of the side plate 2, but the driving stability of the side plate 2 is not as good as that of the two-end synchronous driving. Simultaneously, the bottom of first pneumatic cylinder 4 also is articulated with headwall 3, therefore the flexible pin joint that can drive curb plate 2 around its base of the piston rod of first pneumatic cylinder 4 rotates to open or close the carriage side.

The middle part of the end wall 3 is provided with a connecting seat 5 which is connected with a tilting driving part for driving the carriage to tilt. In this embodiment, the tilting driving part is a second hydraulic cylinder 6, the end of the piston rod of which is hinged to the connecting base 5, and the bottom end of the second hydraulic cylinder 6 is hinged to the vehicle body frame 7.

Meanwhile, as shown in fig. 3, two sides of the bottom plate 1 are both provided with a support 8 which is movably connected with a support seat 9 for supporting the carriage. The support seat 9 can be arranged on the vehicle body frame 7 and other structures and comprises two support rib plates 10 and a support pin 11 fixedly arranged between the support rib plates 10, and the bottom end of the support 8 is provided with an arch-shaped groove 12. When the car is not tilted, the whole car is placed on the body frame 7 with the support pins 11 positioned in the arcuate grooves 12.

When tipping is needed, the side plate 2 on one side is gradually opened through the first hydraulic cylinder 4 on the side, and bulk goods such as ore flow to the side under the action of gravity, so that the gravity center of the whole carriage is shifted to the side. Subsequently, the second hydraulic cylinder 6 gradually applies hydraulic thrust to jack the connecting seat 5 upwards, and both sides of the bottom plate 1 of the carriage are movably connected with the body frame 7, so under the condition of gravity center deviation, the unopened side of the carriage can be firstly jacked in the process of gradually increasing the hydraulic thrust, and when the second hydraulic cylinder 6 continues to pressurize, the connecting seat 5 moves upwards to drive the unopened side of the carriage to rotate around the opened side, the arch-shaped groove 12 of the support 8 on the opened side on the bottom plate 1 and the support pin 11 form a hinge point, the carriage is controlled to roll over to the appointed side, and the goods flow out and unload after the side plate 2 is gradually opened.

When the carriage is horizontal and is not unloaded, the arcuate grooves 12 of the brackets 8 on both sides of the floor 1 are engaged with the corresponding support pins 11, so that the entire carriage is fixed and limited in the horizontal plane and does not deviate. Wherein the longitudinal positioning of the carriage is formed by limiting the side surface of the support 8 by the support rib plate 10.

In order to reduce the occupation of the arrangement space of the carriage, the connecting seat 5 is arranged at the top end position of the end wall 3 in the embodiment, so that the second hydraulic cylinder 6 is arranged at the same height position with the carriage, and the gravity center height of the carriage is reduced. Meanwhile, the connecting seat 5 is arranged at the top end, so that the second hydraulic cylinder 6 can drive the carriage to roll more stably.

As shown in fig. 4, as a preferred embodiment, a plurality of hinges 13 are arranged on the bottom edge of the side plate 2, a hinge seat 14 is correspondingly arranged on the bottom plate 1, and the hinges 13 are inserted into the hinge seats 14 and hinged through pins, so that the hinge joint of the side plate 2 and the bottom plate 1 is more reliable, and the service life of the goods handling device under the action of long-term impact load is longer.

Additionally, the utility model discloses a carriage is fit for miniaturized application, and its tie point with automobile body frame 7 is swing joint, can directly transport carriage hoist and mount, transports goods etc. as the container.

The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
