Description

Technical Field

[0001] The utility model relates to the technical field of straddle carriers, in particular to a straddle carrier capable of hanging wheels. Background Art

[0002] A container is a tool that can be loaded with packaged or unpackaged goods for transportation and is easy to load and unload with mechanical equipment. At present, the straddle carrier of containers is responsible for lifting, transporting and transferring containers to the destination and then unloading them. This requires the straddle carrier to quickly and accurately align its lifting device with the container when lifting it, and to prevent the container from shaking during the transportation and transfer process. The existing technology has the following defects: the straddle carrier is a rigid structure. When encountering obstacles such as potholes or gravel during driving, it is easy to be bumped and cause the container to shake, posing a transportation safety hazard.

[0003] In the published Chinese patent application, publication number: CN220703037U, patent name: container handling vehicle, the prior art includes a gantry, including a first bracket, a second bracket and a third bracket, the second bracket and the third bracket are arranged at intervals along a first direction, the first bracket is hinged to the second bracket, the first bracket can swing relative to the second bracket along a hinge axis, the hinge axis extends along the first direction, the first bracket is fixedly connected to the third bracket: a clamping mechanism, arranged on the first bracket, the clamping mechanism is used to clamp or release the container; a driving mechanism, the bottom end of the second bracket and / or the third bracket is provided with the driving mechanism, the driving mechanism is used to drive the gantry to move. The prior art fixedly connects one end of the first bracket along the first direction to the third bracket, and hinges the other end along the first direction to the second bracket. When the driving mechanism of the second bracket encounters obstacles such as potholes on the road or gravel during driving, the second bracket itself can swing around the hinge point to reduce the shaking of the first bracket, thereby reducing the shaking of the container and ensuring the smooth transportation of the container; when the driving mechanism of the third bracket encounters obstacles such as potholes on the road or gravel during driving, the third bracket and the second bracket can swing around the hinge point as a whole to reduce the shaking of the first bracket, thereby reducing the shaking of the container. The container transporter has a simple structure and stable transportation, and effectively ensures the transportation and installation of the container.

[0004] Although the prior art can solve the above problems, it still has certain limitations in the specific implementation process. In specific implementation, the road surface usually has a certain slope. When the straddle carrier travels on the road surface with a certain slope, since the straddle carrier has a certain height, especially when the straddle carrier is carrying containers, the straddle carrier is relatively high. Under the influence of the road slope, the straddle carrier tilts as a whole, and the center of gravity of the straddle carrier shifts, which can easily cause the straddle carrier to roll over. The prior art cannot effectively solve the problem of the straddle carrier tilting as a whole when traveling on a road surface with a certain slope.

[0005] In summary, in order to solve the problems existing in the prior art, this case is proposed to solve them. Utility Model Content

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0024] See also Figures 1 to 3 The utility model provides a technical solution: a straddle carrier capable of hanging wheels, comprising a roof frame 1 and at least four supporting legs 2, wherein the upper end of each supporting leg 2 is fixedly connected to the roof frame 1, and each supporting leg 2 is respectively arranged below two length sides of the roof frame 1.

[0025] The lower end of each support leg 2 at the lower side of one length of the roof rack 1 is fixedly mounted with a wheel 5. The lower end of each support leg 2 at the lower side of the other length of the roof rack 1 is provided with a suspension component 6, and the lower end of the suspension component 6 is also provided with a wheel 5.

[0026] The supporting legs 2 at the lower side of each length of the roof rack 1 are fixedly connected by a supporting beam 4 .

[0027] The suspension component 6 includes a suspension column 601 and a second driving member 602. The suspension column 601 is inserted into the lower end of the supporting leg 2, and the suspension column 601 is slidably connected to the supporting leg 2. A channel steel 603 is fixedly connected to the outer wall of the lower end of the suspension column 601. The second driving member 602 is hingedly set on the supporting beam 4, and the output shaft end of the second driving member 602 is hinged to the channel steel 603.

[0028] The suspension component 6 is used to adjust the height of the wheel 5 at the lower end of the support leg 2 below the side where one length of the roof frame 1 is located. The suspension component 6 is used to drive the wheel 5 on the side where one length is located to move up and down, thereby adjusting the height of the wheel 5 so that the wheel can adapt to the slope of the road surface, so that the straddle carrier is in a vertical state as a whole, and the straddle carrier is straightened to prevent the straddle carrier from tilting due to the slope of the road surface, thereby ensuring the stability of the center of gravity and preventing the straddle carrier from rolling over.

[0029] The second driving member 602 is used to drive the suspension column 601 to slide and rise on the support leg 2. When the suspension column 601 slides and rises on the support leg 2, it drives the wheel 5 to slide and rise. The wheel 5 is always in contact with the ground. When the suspension column 601 extends out of the support leg 2, the overall height of the support leg 2 is raised; when the suspension column 601 retracts into the support leg 2, the overall height of the support leg 2 is lowered. When the support leg 2 on one length side of the straddle carrier is in a stable state, when the height of the support leg 2 on the other length side is raised or lowered, the straddle carrier can be straightened as a whole, avoiding the straddle carrier from tilting, thereby preventing the straddle carrier from rolling over, and greatly improving the safety and stability of the straddle carrier.

[0030] Specifically, the supporting leg 2 is a square cylinder structure, and the suspension column 601 is a square column structure.

[0031] Among them, by adopting a square cylinder structure for the supporting leg 2 and a square column structure for the suspension column 601, the problem between the supporting leg 2 and the suspension column 601 is improved, ensuring that the supporting leg 2 and the suspension column 601 are in a positive and stable connection.

[0032] Specifically, the support leg 2 is composed of a first cylinder 201 and a second cylinder 202. The first cylinder 201 is slidably connected to the second cylinder 202. The second cylinder 202 is inserted into the lower end of the first cylinder 201. A connecting member 203 is fixedly connected to the outer wall of the middle part of the second cylinder 202. A first driving member 3 is fixedly installed on the outer wall of the first cylinder 201, and the output shaft end of the first driving member 3 is fixedly installed to the connecting member 203.

[0033] Among them, the first cylinder 201 and the second cylinder 202 are lifted and lowered after sliding, thereby realizing the lifting and lowering adjustment of the support leg 2 to adapt to the height adjustment when lifting the container. The first drive member 3 is used to drive the second cylinder 202 to move up and down in the first cylinder 201, thereby adjusting the height of the support leg 2. The first drive member 3 can be a hydraulic cylinder or an electric cylinder. After the first drive member 3 is started, the traction connecting member 203 is raised or lowered, and the connecting member 203 drives the second cylinder 202 to rise or fall. The first drive members 3 on each support leg 2 are started or closed synchronously, that is, the output shafts of each first drive member 3 are extended and retracted at the same time to ensure that the lifting and lowering of each support leg 2 are in a synchronous state.

[0034] The roof frame 1 is composed of two first cross beams 101 and two second cross beams 102. The two ends of the two second cross beams 102 are fixedly connected to the two ends of the two first cross beams 101 respectively. The two first cross beams 101 and the two second cross beams 102 together form a rectangular frame structure. The side where the two first cross beams 101 are located is the two length sides of the roof frame 1.

[0035] The roof frame 1 is a rectangular frame structure with certain stability.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
