Description

Technical Field

[0001] The utility model relates to the technical field of engineering lifting devices, in particular to a heavy-load lifting device used in a container. Background Art

[0002] Wire reels are used to wind electric wires. Due to the weight and volume of power wires and the height limit of container space, a conventional 3.5t forklift cannot lift a 5t wire reel, and a 5t forklift cannot enter a container with limited height for lifting operations. Therefore, it is urgent to develop a simple, convenient and low-cost professional power wire loading and unloading device. Utility Model Content

[0003] The utility model aims to provide a heavy-load lifting device used in a container, so as to provide a heavy-load lifting device suitable for lifting a wire reel in a container.

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] A heavy-load lifting device for use in a container comprises a symmetrically arranged flat base, each flat base being provided with a walking wheel, a hydraulic cylinder and a first pin hole, the hydraulic cylinder driving a lifting plate, the lifting plate being provided with a second pin hole; further comprising a distance adjusting plate and a hydraulic press support, the distance adjusting plate being provided with a plurality of first distance adjusting holes for use in conjunction with the second pin holes on both sides for pin connection, the hydraulic press support being provided with a plurality of second distance adjusting holes for use in conjunction with the first pin holes on both sides for pin connection.

[0006] The working principle and beneficial effects of the utility model:

[0007] Compared with the prior art, the present invention first aligns the first pin hole on the flat base with a second distance adjustment hole on the hydraulic press support and then performs pin connection, that is, the flat bases on both sides and the hydraulic press support are fixedly assembled. Then the distance adjustment plate is moved, and the first distance adjustment hole on the distance adjustment plate is aligned with the second pin hole and then pinned, and the distance adjustment plate plays a role in assisting the fixing of the flat bases on both sides.

[0008] The walking wheels are used to move the flatbed base, push the flatbed base into the container and move it to the space at the bottom of the wire reel, and then drive the jacking plate upward through the hydraulic cylinder. The jacking plates on both sides jack up the wire reel, and then push the flatbed base to move outside the container, completing the lifting operation of the wire reel. In addition, if the number of the second spacing adjustment hole and the first spacing adjustment hole is multiple, the distance between the two flatbed bases can be adjusted to adapt to wire reels of different outer diameters, thereby improving applicability. This application is suitable for lifting operations in containers with limited height.

[0009] Optimally, the plurality of first distance adjustment holes and the plurality of second distance adjustment holes are distributed in the same manner. Since the plurality of first distance adjustment holes and the plurality of second distance adjustment holes have the same distribution spacing and quantity, it is convenient to quickly install the distance adjustment plate and the flat base.

[0010] Optimally, the flat base is provided with a sinking groove, and the hydraulic cylinder is fixedly arranged in the sinking groove. The installation height of the hydraulic cylinder is lowered by using the sinking groove, that is, the height of the lifting plate is lowered to meet the characteristics of low-height operation in the container.

[0011] Optimally, the travel wheel is specifically a wheel axle, which is composed of a steel shaft and a high-strength non-metallic material wheel surface, and bears the functions of load bearing and rolling travel in the system.

[0012] Optimally, the flat base is provided with a traction ring, and the hydraulic press support is provided with a hydraulic press for providing hydraulic force to the hydraulic cylinder. The traction ring is located at the front end of the flat base and forms a whole with the flat base. The two sets of flat bases each have a traction ring, which is a force-bearing component for connecting the device to the traction equipment so that the device can be pulled by the traction machine to move horizontally after completing the vertical lifting task.

[0013] Optimally, the running wheels are symmetrically distributed on both sides of the flat base, and the hydraulic cylinder is located between the running wheels on both sides. This optimization solution can improve the stability during the lifting process.

[0014] Optimally, the number of the first pin hole and the second pin hole is multiple, which can improve the stability of the flat plate bases on both sides and the hydraulic press support during assembly. BRIEF DESCRIPTION OF THE DRAWINGS
