The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The first embodiment is as follows:

as shown in fig. 1, an embodiment of the present invention provides a portable workpiece transportation device, which includes a frame 1, first pillars 2 disposed on two sides of the frame 1, and first wheels 3 disposed at ends of the first pillars 2, wherein one end of the frame 1 is provided with a push rod 4, and the other end is provided with a suspension lock mechanism 5 for clamping a workpiece; the padlock mechanism 5 includes a support rod 51, flexible coupling members 52 provided on both sides of the support rod 51, and clamps 53 provided at the ends of the flexible coupling members 52.

It should be noted that two push rods 4 are preferably arranged and symmetrically arranged on two sides of the frame 1, so that the two hands of the operator can hold the push rods respectively, thereby facilitating the application of force; the flexible connecting element 52 is preferably a lifting rope or an iron chain, so that the position angle of the clamp 53 can be conveniently adjusted by an operator, and the efficiency of clamping a workpiece is improved; the clamp 53 is preferably a hanger rail clamp, so that the workpiece can be clamped automatically after being lifted, and the clamp is simple to operate and high in efficiency; but not limited thereto, the above components may be in other forms, and are not limited thereto.

Specifically, when the device is used, the device is pushed to the right back of a sample, then the two ends of a workpiece are clamped by the clamp 53 of the padlock mechanism 5, then an operator pushes the push rod 4 downwards, the push rod 4 drives one end of the frame 1 to lower downwards, then according to the lever principle, the frame 1 takes the first support column 2 and the first wheel 3 as pivots, so that the end provided with the padlock mechanism 5 is lifted upwards, the support rod 51 is driven to ascend, and the support rod 51 lifts the workpiece up to the ground through the flexible connecting piece 52 and the clamp 53 on the two sides; and finally, keeping the workpiece in a state of being lifted off the ground, and pushing the device so as to start transportation. Through the mode, the lever principle can be utilized to easily and conveniently lift the workpiece off the ground, the operation personnel are not required to lift the workpiece in person, the labor intensity of the operation personnel is reduced, the working efficiency is improved, time and labor are saved, the workpiece can be transported by only one person, and the labor cost is reduced.

In the embodiment, the padlock mechanism 5 comprises a height adjusting assembly 54, the frame 1 is in transmission connection with the support rod 51 through the height adjusting assembly 54, and the height adjusting assembly 54 is used for adjusting the up-and-down height of the support rod 51.

Specifically, the vertical height of the supporting rod 51 is adjusted through the height adjusting component 54, so that the vertical height of the clamp 53 can be adjusted, even if the workpiece is positioned on a shelf instead of on the ground, the workpiece can be lifted through the lever principle, the applicability of the device is improved, and the using effect is better.

In this embodiment, as shown in fig. 3-4, the height adjustment assembly 54 includes a first threaded rod 541 and a first rotating wheel 542, one end of the first threaded rod 541 is fixedly connected to the first rotating wheel 542, the other end is rotatably connected to the supporting rod 51, and the first threaded rod 541 is threadedly connected to the frame 1. The height adjustment assembly 54 further includes a guide rod 543 disposed on the support rod 51, the guide rod 543 is slidably connected to the frame 1.

Specifically, during adjustment, the first rotating wheel 542 is rotated, the first rotating wheel 542 drives the first threaded rod 541 to rotate, and due to the fact that the first threaded rod 541 is in threaded connection with the frame 1, the first threaded rod 541 can synchronously move linearly while rotating, so that the first threaded rod 541 can drive the supporting rod 51 to move up and down, and in the moving process, the supporting rod 51 does not rotate along with the first threaded rod 541 due to the limiting guide of the guide rod 543, and the posture is kept fixed. The mode has a simple structure, is convenient to operate, improves the adjusting efficiency, and saves time and labor.

The second embodiment:

as shown in fig. 1, the present embodiment provides a portable workpiece transportation device, which is different from the first embodiment in that a second pillar 6 is further hinged to the bottom of the frame 1, a second wheel 7 is disposed at the end of the second pillar 6, the second pillar 6 is located between the first pillar 2 and the padlock 5, and a locking mechanism 8 for locking and fixing the second pillar 6 is further disposed on the frame 1.

Specifically, before the workpiece is lifted by the lever principle, the locking mechanism 8 is first temporarily released from locking the second support 6, and then the second support 6 is rotated, so that the second wheel 7 is not locked and fixed again after being in contact with the ground. At the moment, the frame 1 can be levered because the second pillar 6 and the second wheel 7 are not supported; after the workpiece is lifted, the second support column 6 is reset and locked and fixed, so that the second wheel 7 is supported again, and at the moment, the frame 1 is stably supported by three points, and the workpiece can be kept lifted without applying force to the push rod 4 by an operator. By the mode, the labor intensity of operators in the process of transporting the workpieces can be reduced, and the using effect is improved.

In this embodiment, the locking mechanism 8 includes a U-shaped plate 81 disposed at the bottom of the frame 1, the second pillar 6 is hinged to the inner side wall of the U-shaped plate 81, the second pillar 6 is provided with a positioning hole 61, the U-shaped plate 81 is screwed with a second threaded rod 82, one end of the second threaded rod 82 is provided with a second rotating wheel 83, and the other end of the second threaded rod can extend into the U-shaped plate 81 and is inserted into the positioning hole 61.

Specifically, when the second pillar 6 is in a vertical state, and the second wheel 7 is supported by being in contact with the ground, a positioning hole 61 is aligned with the second threaded rod 82 exactly, so at this time, the second rotating wheel 83 is rotated, the second rotating wheel 83 drives the second threaded rod 82 to rotate, and because the second threaded rod 82 is in threaded connection with the U-shaped plate 81, the second threaded rod extends into the U-shaped plate 81 gradually, is clamped with the positioning hole 61 aligned with the U-shaped plate, and at this time, the second pillar 6 is clamped and cannot rotate any more, so that the locking mechanism 8 is fixed to the second pillar 6. Similarly, when the second support 6 is in a horizontal state, so that the second wheel 7 is not in contact with the ground, the other positioning hole 61 is aligned with the second threaded rod 82, and the second support 6 can be locked and fixed by repeating the above operations. The method is simple to operate and convenient to implement, the adjusting efficiency is improved, and the time is saved.

In addition, the tail end of the push rod 4 is provided with a grab handle 9, so that an operator can conveniently hold the push rod 4 and the lever is prevented from slipping off when being pried.

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