Description

Technical Field

[0001] The utility model relates to the technical field of overhung cranes, and more specifically, to a bracket for adjusting the height of an overhung crane. Background Art

[0002] With the progress of society, the number and places of use of overhung cranes are increasing continuously. Overhung cranes are sometimes used when a gas turbine exits the cabin from the box. During the process of lifting heavy objects by the overhung crane, due to the uncertainty of the site, the overall height of the crane may be insufficient or the crane may not be on the horizontal line. Therefore, it is particularly difficult to adjust the height and level of the overhung crane during the commissioning process, and it will also increase the installation time and labor costs.

[0003] Therefore, a bracket for adjusting the height of an overhung crane is needed to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a bracket for adjusting the height of an overhung crane; to solve the above technical problems, the utility model provides the following technical solutions: a bracket for adjusting the height of an overhung crane, including a set of overhung crane protection parts, trapezoidal nuts, trapezoidal lead screws, handwheels, fixing plates and matching bolts. Two or more sets of brackets for adjusting the height of an overhung crane must be equipped on a set of overhung cranes.

[0005] Preferably, to ensure that the bracket for adjusting the height of an overhung crane does not deform when subjected to a large force, the overhung crane protection parts, trapezoidal nuts, trapezoidal lead screws, knurled handwheels, and fixing plates are all made of 316L (022Cr17Ni12Mo2) stainless steel.

[0006] Preferably, the overhung crane protection part is composed of two identical 3mm overhung crane protection plates Ⅰ and another 3mm overhung crane protection plate Ⅱ welded together. The overhung crane protection part is connected to the fixing plate on the overhung crane base by bolts. The trapezoidal nut is welded to the overhung crane base. The trapezoidal lead screw is threadedly connected to the trapezoidal nut. The fixing plate is welded to the overhung crane base. The fixing plate is threadedly connected to the overhung crane protection part. The knurled handwheel is spot welded to the trapezoidal lead screw at three points. Advantageous Effects

[0007] A bracket for adjusting the height of an overhung crane can adjust the height of the entire overhung crane by adjusting the trapezoidal lead screw, avoiding the situation where the overhung crane cannot be adjusted when the height is insufficient, and there is no need to re-design and adjust the height on site, which reduces the labor intensity of the staff to a certain extent. Due to the existence of the overhung crane protection part, the ground can also be not damaged during the adjustment process.

[0008] Generally, two sets of brackets for adjusting the height of the overhanging crane are equipped on the base of the overhanging crane. During the installation process, the overall overhanging crane can be made horizontal by adjusting the heights of the brackets respectively, avoiding the problem that the overhanging crane cannot be kept horizontal at the installation site. Due to the existence of the overhanging crane protection parts, the ground can also be not damaged during the adjustment process. Brief Description of the Drawings
