Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to an auxiliary device for hoisting columns. Background Technology

[0002] As a crucial component of stacker cranes, the uprights, once erected, are assembled with other parts to form the crane. Due to their length and weight, hoisting the uprights is a challenging task at the construction site of an automated warehouse where stacker cranes are being assembled. A mobile crane is needed to move the uprights from a horizontal to an vertical position. During this process, the lower part of the upright in contact with the ground will shift relative to the ground as the crane is raised. The metal surface of the upright rubs directly against the ground, generating significant vibration and accompanied by harsh friction noise, which can negatively impact the upright structure. There is also a risk that the hoisting straps may break due to excessive pulling, greatly increasing safety hazards throughout the hoisting process. Furthermore, the significant displacement between the upright and the ground creates noticeable friction marks, reducing the flatness of the ground. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the risk of the lifting straps being torn off due to direct friction between the metal surface of the column and the ground during the hoisting of the column in the prior art. In this way, an auxiliary device for hoisting the column is provided, which avoids direct contact between the lower end of the column and the ground by rolling contact with the ground through the rolling element, reduces the impact on the column and the ground, and can also alleviate the phenomenon of excessive pulling of the lifting straps, thereby reducing the safety hazards during the hoisting process.

[0004] To solve the above-mentioned technical problems, this utility model provides a column hoisting auxiliary device, comprising, A fixed mounting base is provided with multiple connection holes; Multiple rolling elements are symmetrically and coaxially arranged on both sides of the fixed mounting base, and all of the multiple rolling elements are rotatably connected to the fixed mounting base. The lowest point of the multiple rolling elements is set below the bottom of the fixed mounting base. A column mounting bracket is disposed on the fixed mounting base. The column mounting bracket has a first strip hole, and the first strip hole is connected to the connecting hole by a fastener.

[0005] In one embodiment of this utility model, the column mounting bracket is further provided with a second strip hole, and the second strip hole is connected to the column by a fastener.

[0006] In one embodiment of this utility model, the column mounting bracket includes a horizontal plate and a vertical plate vertically connected to the horizontal plate. The horizontal plate is provided with the first strip hole, and the vertical plate is provided with the second strip hole.

[0007] In one embodiment of this utility model, the rolling element is configured as a rolling bearing or a roller.

[0008] In one embodiment of this utility model, a baffle, a shaft core connected to the baffle, and an end plate connected to the shaft core are provided on both sides of the fixed mounting base. The baffle is connected to the fixed mounting base, the shaft core is interference-fitted with the inner ring of the rolling bearing, and the baffle and the end plate abut against both sides of the rolling bearing respectively.

[0009] In one embodiment of this utility model, the end plate is fixedly connected to the end of the shaft core by screws.

[0010] In one embodiment of the present invention, the invention further includes multiple sets of connecting holes, which are linearly distributed along the axial direction of the rolling element.

[0011] In one embodiment of this utility model, multiple sets of connecting holes located in the middle of the fixed mounting base are equidistantly distributed, multiple sets of connecting holes located at both ends of the fixed mounting base are equidistantly distributed, and the spacing between the multiple sets of connecting holes located in the middle is smaller than the spacing between the multiple sets of connecting holes located at both ends.

[0013] In one embodiment of the present invention, a perforated plate is welded or screwed to the fixed mounting base, and the perforated plate is provided with the connecting hole.

[0014] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects: The column hoisting auxiliary device of this utility model connects the lower end of the column to the column mounting bracket. When the lower end of the column moves relative to the ground, the rolling element rolls freely on the ground, transforming the sliding contact between the lower end of the column and the ground into a rolling contact between the rolling element and the ground, thus avoiding direct contact between the lower end of the column and the ground and reducing the impact between the column and the ground.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

This device includes... The mounting base 1 is provided with multiple connection holes 74; Multiple rolling elements are symmetrically and coaxially arranged on both sides of the fixed mounting base 1. All of the multiple rolling elements are rotatably connected to the fixed mounting base 1. The lowest point of the multiple rolling elements is set below the bottom of the fixed mounting base 1. The column mounting bracket 3 is disposed on the fixed mounting base 1. The column mounting bracket 3 is provided with a first strip hole 311, and the first strip hole 311 is connected to the connecting hole 74 by a fastener 8.

[0019] The column hoisting auxiliary device described in this embodiment connects the lower end 4 of the column to the column mounting bracket 3. When the rolling element is on the ground, the fixed mounting base 1 is higher than the ground, preventing the fixed mounting base 1 from contacting the ground. When the lower end 4 of the column moves relative to the ground, the rolling element rolls freely on the ground, transforming the sliding contact between the lower end 4 of the column and the ground into a rolling contact between the rolling element and the ground. This avoids direct contact between the lower end 4 of the column and the ground, thereby reducing the impact between the column and the ground and making the movement of the lower end 4 of the column smoother, reducing the phenomenon of excessive pulling of the hoisting straps. By setting multiple connecting holes 74 on the fixed mounting base 1, the position of the column mounting bracket 3 can be adjusted, and different numbers of column mounting brackets 3 can be connected, thus being compatible with the hoisting of columns of different specifications and improving the versatility of the device.

When the lower end 4 of the column is connected to the column mounting bracket 3, the second strip-shaped hole 321 is aligned with the end connection hole 41 of the column. The column and the column mounting bracket 3 are fixedly connected by inserting a screw through the second strip-shaped hole 321 into the connection hole 74.
