As shown in fig. 1-3, a self-adaptive adjustment hoist size straddle carrier includes a frame 1 as an integral structural support for the straddle carrier; slide beams 3 oppositely arranged at two sides of the frame 1; the adjusting mechanism is arranged on the sliding beam 3 and comprises a sliding cylinder 30 and a plurality of adjusting cylinders; the method is characterized in that: the adjusting oil cylinder drives the sliding cylinder 30 to stay at least at a first position and a second position through telescopic movement, so that hoisting operations for containers with different sizes are realized. In this patent technical scheme, on the technical path of traditional straddle carrier, through the adjustment at the container width direction span of its hoist and mount to match the container hoist and mount of different width dimensions. The frame 1 is a main body part of the straddle carrier, is of a substantially cuboid structure, and is provided with ground wheels at the bottom for transportation after lifting the container. The frame 1 is formed by welding a plurality of metal profiles and has the performance of bearing high-strength load. The frame 1 is further provided with devices such as an electrical element, a power system, a control system, etc., which are already embodied in the prior art and are not described herein. The sliding beam 3 is two spandrel girders which are oppositely arranged on the frame 1, and the gravity load during hoisting operation is finally transferred to the sliding beam 3 and other spandrel girders for bearing. The adjusting mechanism is arranged on the sliding beam 3, and the principle of adjusting the span of the adjusting mechanism is as follows: the oil cylinder stretches to drive the sliding cylinder to stay at different positions on the sliding beam 3, so that the span is increased or reduced, and different container hoisting is matched.
In the technical scheme of the patent, at least one sliding cylinder 30 is arranged and sleeved on the sliding beam 3; the sliding cylinder 30 performs sliding displacement relative to the sliding beam 3 under the action of external force. In the specific embodiment, as shown in fig. 2, the sliding cylinders 30 are two oppositely arranged, and the lifting of different containers is realized by adjusting the positions of the two sliding cylinders 30. The design of two sliding cylinders 30 which can slide independently relative to the sliding beam 3 has the advantages that when the span is adjusted, the same distance is adjusted at the two ends of the sliding beam 3 relative to the frame 1, so that the geometric centers of the container and the frame 1 are approximately coincident when the container is hoisted, the stability and less shaking amplitude of the container are ensured when the straddle carrier walks, and the energy consumption is reduced. The sliding cylinder 30 is sleeved on the sliding beam 3, so that the gravity load transferred to the sliding cylinder 30 during container lifting can be fully transferred to the sliding beam 3; the two are sleeved, so that the stressed contact area is increased, the stress concentration is reduced, and the whole service life of the equipment is prolonged.
The adjusting oil cylinder comprises a sliding oil cylinder 6 and a side-shifting oil cylinder 5, and the adjusting mechanism provides displacement power and stable maintenance of the sliding cylinder 30 on the sliding beam 3. The fixed end of the side-shifting cylinder 5 is fixedly connected to the corresponding beam of the frame 1, and the telescopic end is connected to the connecting seat 40. The connection between the two sliding cylinders 6 is formed by connecting the sliding cylinder 6 with a connecting seat 40 on the sliding cylinder 30. The telescopic end and the fixed end of the sliding cylinder 6 are respectively connected to the two connecting seats 40, when the sliding cylinder 6 performs telescopic movement, the distance between the two sliding cylinders 30 is increased or shortened, and therefore the lifting mechanism connected with the sliding cylinders 30 is driven to perform span transformation, and lifting of containers of different sizes is achieved.
A connecting rib 41 is arranged on the outer wall of the sliding cylinder 30, and the other end of the connecting rib 41 is connected with the connecting seat 40; the connecting seat 40 is provided with a hinge hole hinged with the oil cylinder.
The sliding cylinder 30 is provided with a roller 16, and the chain is driven to stretch and retract by the rotation of the roller 16, so that the height of the container is adjusted when the container is hoisted; the chain transfers the gravitational load of the lifting container to the slipping drum 30. The chain rotates around the roller 16 to drive the hoisted container to rise and fall, and the roller is arranged on the sliding cylinder through a fixed rib plate or in other integrated forming modes.
The sliding cylinder 30 is also provided with a fixing plate 15, and the fixing plate 15 provides fixing of the roller 16 and is used as a limit of the lifting height of the container when the container is hoisted. When the lifting appliance of the straddle carrier is driven by the chain and rises to a position close to the sliding cylinder 30, the protruding notch type design below the fixed plate 15 is the structure closest to the lifting appliance, and when the lifting appliance is close to the lower side of the fixed plate 15, the lifting appliance is blocked and limited by the notch type design, so that the whole straddle carrier is protected from being damaged.
When the sliding cylinder 30 stays at different positions relative to the sliding beam 3, the sliding cylinder corresponds to the lifting of containers with different sizes. The sliding drums 30 can slide on the sliding beam 3 relative to one side of the frame 1, or the two sliding drums 30 can relatively move on the sliding beam 3, and the span of the straddle carrier is changed under the condition that the sliding drums 30 are displaced. The specific design parameters can be set according to most container types commonly used in the operation scene.
The sliding cylinder 6 and the side-shifting cylinder 5 have horizontal coaxiality, and the sliding cylinder 6 and the side-shifting cylinder 5 jointly adjust the position of the sliding cylinder 30 on the sliding beam 3 and keep the sliding cylinder stable. Coaxiality is achieved between the adjusting cylinders, so that interaction of radial forces can be avoided when interaction forces are generated.
When the device is used, the expansion and contraction of the sliding cylinder 6 is regulated, the sliding cylinder 30 is driven to slide on the sliding beam 3, and the sliding cylinder 30 is stopped at the corresponding position on the sliding beam 3 according to the size of a container to be hoisted, so that the container is hoisted.
According to the technical scheme, the sliding cylinder is moved relative to the sliding beam, so that the sliding cylinder can stay at different positions on the sliding beam, and further the span adjustment required by containers with different specifications is matched. So that one straddle carrier can realize the hoisting and transferring of containers with different sizes. Meanwhile, the technical scheme has simple structure, can be directly improved and used on the basis of the prior art, and has lower required improvement cost.
Finally, it should be noted that: the foregoing description of the preferred embodiments of the present utility model is not intended to be limiting, but rather, although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
