Description

Technical Field

[0001] The utility model relates to the technical field of containers, and more specifically, to a self-lifting moving wheel suitable for temporary transportation of containers and pallets on a leveled site and a moving device composed of the wheels. Background Art

[0002] With the development of the national economy, container transportation plays an increasingly important role. However, due to the heavy weight of containers, loading and unloading often become the key factors in container transportation.

[0003] The handling of containers mainly relies on container handling machinery and equipment, mainly including container forklifts, reach stackers, stackers, etc. In large ports, warehouses and other places, the number of the above equipment is relatively sufficient, and the supporting operators are in place at a high rate, which can achieve fully mechanized operations. However, in small warehouses, temporary yards, factory buildings, and other types of unit yards / yards, when containers need to be handled, the corresponding operating equipment is often insufficient or missing. In addition, ordinary material handling equipment is not specially designed for container operations, and there are problems such as insufficient working weight and insufficient fork arm spacing in actual use. Truck cranes need to be used with container spreaders, which have low efficiency and difficulty in obtaining spreaders.

[0004] At present, there are already container casters with auxiliary lifting functions, temporary mobile wheels and other transfer products on the market that meet the needs of temporary container transfer. For example, the patent application with patent application number 201510741028.5 and invention name "Mechanical container loading and unloading transfer tool and mechanical container loading and unloading transfer system" discloses a transfer system, including a walking component, an intermediate connection component and a box connection component that can be fixedly connected to the container body, the intermediate connection component is mounted on the column of the walking component, and the intermediate connection component is connected to the box connection component. When the transfer system is lifting, the main fixed position is the lower corner piece and column of the container. The transferred and transported box must have a complete column. Therefore, the transfer system cannot be applied to the transfer of half-height and platform containers, and cannot be applied to pallet transfer. The patent application with the patent application number of 200710177283.7 and the invention name of "Hydraulic unit, caster assembly and container moving device and method" discloses a container moving device, including a hydraulic unit, a walking unit and a positioning clamping unit, etc. The walking unit includes a caster bracket connected to the piston of the hydraulic unit and four casters arranged on the caster bracket. The device only uses the lower corner piece of the container. The main problem in application is that there is a large eccentric moment during lifting. When conventional materials are used, the lifting weight is limited, and it is also not applicable to pallet transportation. Therefore, it is of great practical value to develop a transfer device with self-lifting function, suitable for containers and pallets, and requiring fewer operators. Utility Model Content

[0027] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The schematic diagram of the self-lifting container and pallet moving wheels of the utility model is as follows Figure 1-Figure 6 As shown, it includes a supporting structure, a walking structure and a lifting structure.

[0029] The support structure includes a crossbeam 1 for inserting into a fork groove 12 of the object to be transported, and two ends of the crossbeam 1 are respectively provided with a T-slot 11 formed by two symmetrically arranged positioning blocks 2. The length of the crossbeam 1 is greater than the width of the object to be transported, and the cross section of the crossbeam 1 is smaller than the minimum size of the fork groove of the object to be transported. The material of the crossbeam 1 is preferably Q235 steel.

[0030] The walking structure includes a wheel frame 5 and a plurality of groups of walking wheels 4 symmetrically mounted on the wheel frame 5 .

[0031] The lifting structure includes two lifting units corresponding to the T-slots 11 at both ends of the beam, and each lifting unit includes a cylinder and a hydraulic pump that provides hydraulic power to the cylinder. The cylinder includes a cylinder body 8, a hydraulic rod and a top body 6. One end of the hydraulic rod is installed in the cylinder body 8, and the other end is fixedly connected to the top body 6. The cylinder body 8 corresponds to the lower part of the T-slot and is rotatably connected to the wheel frame 5 through a bearing 7. The hydraulic rod and the top body 6 correspond to the upper part of the T-slot. When in use, the upper end of the top body 6 is connected to the beam 1 to provide lifting force. The outlet of the manual hydraulic pump is connected to the cylinder body 8 to provide hydraulic power to the cylinder.

[0032] The two positioning blocks 2 are respectively provided with safety bolt insertion holes 9, and the safety bolt 3 for preventing the oil cylinder from being separated from the cross beam passes through the T-slot and the corresponding safety bolt insertion holes to ensure the safety and stability of transportation.

[0033] In order to improve the stability of transportation, the top body 6 is coated with a shock-absorbing and anti-slip sleeve, and the material of the shock-absorbing and anti-slip sleeve is preferably rubber material.

[0034] Furthermore, the wheel frame 5 is a rectangular frame, and the running wheel 4 is a rubber wheel.

[0035] Furthermore, a bubble level 10 for detecting the horizontality of the container in the width direction is placed on the crossbeam 1 .

[0036] The above two sets of self-lifting containers and pallet moving wheels form a mobile device, which is used for emergency handling of containers in small warehouses and yards. Its total height is variable in the range of 125-135mm, and the total weight of the container that can be lifted is ≤12 tons. The moving ground is required to be relatively flat, with a slope of ≤0.5%, and a maximum moving speed of ≤5km / h, which can meet the installation and lifting requirements of 20-foot ISO containers under normal circumstances. In addition to supporting ordinary containers of 20 feet and below, it is compatible with bench-type and platform containers with fork grooves and various types of pallets on the premise of meeting the minimum height of the bottom plate from the ground, and has a wide range of adaptability.

[0037] When in use, the number of operators is 2. Taking the container as an example, the specific operation method is as follows:

[0038] (1) Insert the crossbeams of each self-lifting container and pallet moving wheel into the fork grooves under the container. For containers with four fork grooves, a set of symmetrical fork grooves should be selected, preferably the outer fork grooves.

[0039] (2) Insert the cylinder body, hydraulic rod and top body of the lifting structure into the T-slots at both ends of the corresponding crossbeams. When the bottom stop of the container fork slot is high and the running wheels cannot touch the ground, the lifting structure can be lifted and hung into the T-slot. When there is no bottom stop in the fork slot, the crossbeam needs to be lifted and pushed into the lifting structure.

[0040] (3) Connect the manual hydraulic pump to two oil cylinders on a beam. Two people press down the manual hydraulic pump rod at the same time to provide hydraulic power to the oil cylinder. The hydraulic rod drives the top body to lift the beam under the action of hydraulic power. Observe the bubble level. First, lift the beam to ensure that the width of the container is horizontal, and finally lift the beam to ensure that the width and length are both horizontal.

[0041] (4) Insert the safety pin at the T-slot to push the container body to move. During the movement, the wheel frame rotates as a whole to achieve steering through the action of the bearing.

[0042] The use of pallets with fork grooves is the same as above.

[0043] The self-lifting container and pallet moving wheels of the utility model and the moving device composed of them are suitable for small warehouses, yards and other places. In addition to supporting ordinary containers of 20 feet and below, they are compatible with bench-type and platform-type containers with fork grooves and various pallets under the premise of meeting the minimum height of the bottom plate from the ground. Without the assistance of operating equipment, it relies on its own lifting capacity to complete the lifting and movement of the box or pallet, and transports single-layer stacked containers over short distances. The installation is convenient and quick, which reduces the operation time, improves the transportation efficiency, and reduces the transportation operation cost. At the same time, after disassembly, the whole is in a long strip shape with a small volume, which is convenient for edge storage.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
