Embodiment Construction

[0020] Such as figure 1 As shown, an embodiment of a crane walking beam, the walking beam in this embodiment includes a beam body 1 extending along the front and rear directions for bearing pressure on the pressure-bearing rail 8, and the front and rear ends of the beam body 1 are respectively rotated and assembled. There is the traveling wheel 9 rollingly matched with the top pressure bearing surface of the pressure bearing track. A left horizontal wheel device 100 and a right horizontal wheel device 200 are installed on the beam body 1 for cooperating to limit the left and right offset of the traveling beam on the bearing rail 8 in the left and right direction.

[0021] The structure of the two horizontal wheel devices is the same, taking the right horizontal wheel device as an example, the right horizontal wheel device includes a horizontal wheel connecting frame 2 fixed on the beam body 1 and fixedly assembled with the horizontal wheel connecting frame 2 to be installed on...

Abstract

The invention provides a small-tonnage crane, a traveling beam thereof and a horizontal wheel device for the traveling beam. The traveling beam comprises a beam body, a left horizontal wheel device and a right horizontal wheel device are mounted on the beam body, each of the left horizontal wheel device and the right horizontal wheel device comprises a horizontal wheel carrier, a horizontal wheel and a horizontal wheel connecting frame, and each horizontal wheel connecting frame is fixedly arranged on the beam body integrally or in a split manner. A moving adjustment structure for guiding each horizontal wheel carrier to achieve guide moving adjustment on the corresponding horizontal wheel connecting frame along the left-right direction is arranged between the horizontal wheel carrier and the horizontal wheel connecting frame of each horizontal wheel device, and a fixing structure for fixedly assembling the horizontal wheel carrier and the horizontal wheel connecting frame when the horizontal wheel carrier with the horizontal wheel is adjusted to be in place by moving is further arranged between the horizontal wheel carrier and the horizontal wheel connecting frame. The traveling beam has the advantages that since the positions of the horizontal wheel carriers in the left-right direction can be adjusted through the moving adjustment structures, the horizontal wheel devices an be adjusted according to the practical conditions, and normal and effective operation of the horizontal wheel devices is guaranteed.

Description

technical field [0001] The invention relates to a small-tonnage crane and its traveling beam and a horizontal wheel device for the traveling beam. Background technique [0002] In some specific places of use and specific industries, lifting equipment is required to be equipped with horizontal wheels to regulate the normal operation of the lifting equipment and avoid rail gnawing. The size of the horizontal wheel of conventional lifting equipment is relatively large, and it is uncoordinated to install on a small-tonnage crane. The weight is relatively large, the installation size requirements are strict, and disassembly is also inconvenient. [0003] In the Chinese utility model patent whose authorized announcement number is CN202936106U, an anti-gnawing rail mechanism of a crane is disclosed, which mainly installs a set of horizontal wheel sets on the two heads of the end beam of the crane respectively, and the horizontal wheel sets include two The horizontal wheels are res...
