[0020] Example 1 like Figures 1-3 The illustrated lifting and supporting transport device includes a pallet jack 1, an inner cylinder 2 vertically mounted on the pallet jack 1, an outer cylinder 3 fitted onto the inner cylinder 2, a nut 4 fixed on the inner cylinder 2, a screw 16 inserted into the inner cylinder 2 and threadedly engaged with the nut 4, a bearing assembly 15 mounted on the top of the screw 16, the bearing assembly 15 mounted on the bottom of a gearbox 11, the outer cylinder 3 fitted onto the outer ring of the bearing assembly 15 and fixed to the gearbox 11, a handle 5 driving the gearbox 11 to rotate the bearing assembly 15, the centerlines of the inner cylinder 2, outer cylinder 3, nut 4, and screw 16 coincide; a hanging arm 18 fixed to the side of the outer cylinder 3 for holding, and a pin 19 at the bottom of the hanging arm 18 for locking.
[0021] Therefore, the lifting function is achieved by using a screw drive, and the ability of the pallet jack to rotate, move forward and backward on its own is utilized. A bevel gear drive is adopted, and a manual operation interface is set radially. The direct drive motor drives the screw through an axial reducer to achieve power-driven lifting. The hanging arm is fitted into the middle section of the outer sleeve in the form of a clamp to support and bear the weight of the box being transported. The hook, pin shaft and limit combination together realize the connection of the box being transferred. They are used in pairs to ensure the synchronous lifting and transfer requirements of the boxes.
[0022] Example 2 Based on embodiment 1, a connecting sleeve 10 is installed on the top of the gearbox 11, a reducer 8 is installed on the top of the connecting sleeve 10 and passes through the connecting sleeve 10 to coaxially drive the bearing assembly 15, and a motor 9 is connected and installed on the top of the reducer 8.
[0023] Furthermore, the motor 9 is driven by the motor driver 14, which is connected and controlled by the control box 7. The control box 7 is installed on the side of the reducer 8, and the motor driver 14 is installed on the back of the hanging arm 18.
[0024] Furthermore, the control box 7 is also connected to control the movement of the ground bull 1.
[0025] Furthermore, nut 4 is fixed at the top of inner cylinder 2.
[0026] Example 3 Based on embodiment 1, a drive wheel 6 is installed at the end of the handle 5 inside the gearbox 11, and a bevel gear 13 is fixed on the input shaft of the bearing assembly 15. The drive wheel 6 and the bevel gear 13 mesh and transmit power.
[0027] Furthermore, the handle 5 and the drive wheel 6 are removable.
[0028] Furthermore, a limiter 17 is installed in the middle of the hanging arm 18 for connection and fixation.
[0029] Furthermore, a hook 12 is installed on the top of the hanging arm 18 for locking.
[0030] Furthermore, the front of the hanging arm 18 is curved.
[0031] Example 4 Based on the above embodiments, the pallet jack 1 connects to the inner cylinder 2 for support and transfer. The inner cylinder 2 and nut 4 are screwed together to form a rigid body. The screw 16 is screwed together with the bearing assembly 15 and gearbox 11 to form a rigid body. The inner cylinder 2 is fitted inside the outer cylinder 3. The middle section of the screw 16 is radially positioned and axially stressed by the bearing assembly 15. The drive wheel 6 and bevel gear 13 are installed in the gearbox 11. The handle 5 can be used to manually drive the screw 16 to rotate forward and backward to achieve lifting. The operation control box 7 directly controls the pallet jack 1 to perform rotation, forward, and backward operations. The connecting sleeve 10 is threaded through the tail end of the screw 16 and screwed to the reducer 8. The motor 9 can directly drive the screw 16 to rotate forward and backward to achieve lifting through the reducer 8. The hanging arm 18 is screwed and mounted between the two steps of the outer cylinder, directly connecting to the housing and bearing the weight of the housing. The motor driver 14 directly drives the motor 9. The hook 12 and the pin shaft 19 are directly connected to the housing, and the limit 17 ensures that the housing connection is secure and reliable. Typically, this lifting support and handling device needs to be used in pairs to meet the requirements for transferring the container.
[0032] The top flange of the pallet jack 1 is bolted to the inner cylinder 2. It has its own drive to realize the functions of rotation, forward and backward movement. At the same time, it has its own control box 7 to realize the rotation, forward and backward operation control of a single unit or multiple units synchronously.
[0033] The upper end of the inner cylinder 2 is rigidly connected to the nut 4, and its lower end is rigidly connected to the ground jack 1. The nut 4 is connected to the screw 16 and fitted inside the outer cylinder 3. Rotating the screw 16 in both directions enables the inner cylinder 2 to extend and retract within the outer cylinder 3.
[0034] The screw 16 is positioned inside the outer cylinder 3 via the bearing assembly 15 and the gearbox 11. A bevel gear 13 is installed in the middle section of the screw 16 to enable manual lifting operation. A connecting sleeve 10 is fitted on the top of the screw 16 to connect the reducer 8 and the motor 9, thereby enabling automatic lifting operation.
[0035] The motor 9 is controlled by the motor driver 14 to achieve forward and reverse rotation, and the screw 16 is driven to rotate forward and reverse through the reducer 8, so as to realize the extension and retraction of the inner cylinder 2 within the outer cylinder 3.
[0036] The hanging arm 18 is screwed onto the middle section of the outer cylinder 3 and is connected and fixed to the box being transported via hook 12, pin shaft 19 and limit 17.
[0037] The drive wheel 6 is installed in the radial hole of the gearbox 11 and is used in combination with the bevel gear 13. The handle 5 is inserted into the tail end of the drive wheel 6, and the screw 16 is manually driven to rotate in both directions by rotating the handle 5, so as to realize the telescopic operation of the inner cylinder 2 in the outer cylinder 3.
[0038] Therefore, this invention can be used in pairs, synchronously lifting the transported container to a specified height above the ground to achieve the transfer of the container. Upon arrival at the designated location, they are synchronously lowered to the ground, and the connection between the lifting support and the transported container is released, thus completing the container transport. Specifically, after the transported container is lifted to a certain height, the transport device can be operated to perform the necessary rotation, forward movement, and backward movement to achieve the relocation of the transported container. The transport interfaces of the transported containers are usually set in two symmetrical or two symmetrical sets, front and back. Depending on the docking interface of the transported container, two or four transport devices are used to achieve the relocation of the transported container.
[0039] Those skilled in the art will understand that the above embodiments can be modified in form and detail in practical applications without departing from the spirit and scope of the invention.
