[0002] Larger tonnage cranes generally include a main beam and single-sided end beam structures symmetrically arranged at both ends of the main beam. The single-sided end beam structures run on corresponding tracks, thereby realizing the transshipment of larger tonnage goods.

[0003] For example, the Tesla 160 / 100t crane has a single-side end beam structure that includes two sets of operating mechanisms. To achieve a greater load-bearing effect, each set of operating mechanisms needs to be connected to multiple ground rail wheels through a balance beam. It is difficult to assemble multiple ground rail wheels in a straight line. Multiple ground rail wheels are offset diagonally relative to the corresponding ground rails, resulting in severe rail gnawing during operation.

[0004] In order to solve the rail gnawing problem caused by the overall diagonal offset of multiple ground rail wheels, the applicant has designed an operating mechanism and a crane with a balance beam correction function, which can correct the deviation of multiple ground rail wheels through a balance beam.

DETAILED DESCRIPTION

[0036] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0037] like Figure 1-Figure 7A specific embodiment of an operating mechanism with a balance beam correction function of the utility model shown in the figure comprises a fixing device 1, a balance beam 3 and two groups of trolleys 4, wherein the balance beam 3 is adjusted and installed with the fixing device 1 through a correction device 2, the balance axis of the balance beam 3 is consistent with the extension direction of the corresponding ground rail, the two groups of trolleys 4 run on the corresponding ground rail through ground rail wheels 42, and are respectively installed at both ends of the balance beam 3, the correction device 2 comprises a mounting seat 21 fixedly mounted on the balance beam 3 and an eccentric oblique shaft 22 installed in the mounting seat 21, when the arrangement straight line of the plurality of ground rail wheels 42 is offset obliquely from the corresponding ground rail, the eccentric oblique shaft 22 is rotated and installed in the mounting seat 21.

[0038] It should be further explained that the fixing device 1 includes a fixing plate 11, a fixing seat 12 fixedly connected to the fixing plate 11 by bolts, and a first axial hole opened on the fixing seat 12, and the center line of the first axial hole and the balance axis of the balance beam 3 are perpendicular to each other in the horizontal plane. A through hole for setting a mounting seat 21 is opened in the middle position of the balance beam 3, and a second axial hole for passing an eccentric oblique shaft 22 is provided on the mounting seat 21, wherein the center line of the first axial hole coincides with the center line of the second axial hole.

[0039] The balance beam 3 of the utility model is installed by adjusting the deviation correction device 2 and the fixing device 1, that is, when the multiple ground rail wheels 42 are offset diagonally as a whole, the eccentric inclined shaft 22 is inserted into the mounting seat 21 while rotating, and the balance axis of the balance beam 3 is adjusted by using the eccentric angle of the eccentric inclined shaft 22, so as to realize the rotation adjustment of the overall arrangement straight line of the multiple ground rail wheels 42, thereby solving the rail gnawing problem caused by the overall diagonal offset of the multiple ground rail wheels 42 in the prior art.

[0040] like Figure 4 and Figure 5 As shown, the eccentric oblique shaft 22 in this embodiment includes a left shaft head 221, a right shaft head 222 and an intermediate oblique shaft 223 arranged between the left shaft head 221 and the right shaft head 222; wherein, the axis of the left shaft head 221 coincides with the axis of the right shaft head 222, and the axis of the intermediate oblique shaft 223 does not coincide with the axes of the left shaft head 221 and the right shaft head 222.

[0041] As an implementation method, the angle between the axis of the middle oblique axis 223 and the axis of the left shaft head 221 and the right shaft head 222 is an eccentric angle a, wherein 0°<a<1°. Because the deflection angle is small, an angle enlargement diagram is provided in the drawings of this embodiment, such as Figure 6 shown.

[0042] like Figure 1 and Figure 3As shown, the trolley 4 includes: a frame 41 connected to the end of the balance beam 3 through a connecting member 43; at least one ground rail wheel 42 installed on the frame 41 and connected to the ground rail. As a preferred embodiment, each trolley 4 is equipped with two ground rail wheels 42.

[0043] The operating mechanism in this embodiment also includes a power source assembly 5 for driving the trolley 4 to operate, and the power source assembly 5 includes a connecting frame 51 installed on a trolley 4 and a driving motor 52 installed on the connecting frame 51, wherein the output shaft of the driving motor 52 is coaxially arranged with a ground rail wheel 42, the ground rail wheel 42 is an active ground rail wheel 42, and the other ground rail wheels 42 are driven ground rail wheels 42. It should be understood that each trolley 4 can be provided with one power source assembly 5 or one power source assembly 5 can be provided on two trolleys 4, as long as it can drive the trolley 4 to operate. There is no absolute limitation on the number of power source assemblies 5 and on which trolley 4 they are specifically installed.

[0044] The use process of this operating mechanism is as follows: start the motor in the power source assembly 5 to drive the two trolleys 4 to run along the ground rail. When the ground rail wheel 42 starts to gnaw the rail or the center of the detected multiple ground rail wheels 42 is not on the vertical plane where the corresponding ground rail is located, it means that the axis of the overall arrangement of the multiple ground rail wheels 42 in this embodiment is deviated from the extension line of the ground rail. According to the deflection angle of the overall arrangement straight line of the ground rail wheels 42, adjust the production of the eccentric inclined shaft 22 with the corresponding eccentric angle, and insert the eccentric inclined shaft 22 into the mounting seat 21 at the corresponding angle. During assembly, the second axial hole on the mounting seat 21 and the first axial hole on the fixed seat 12 are installed on the same center line. When the eccentric inclined shaft 22 is inserted into the mounting seat 21, it drives the balance beam 3 and the overall arrangement of the multiple ground rail wheels 42 to rotate in a straight line. Refer to Figure 7 .

[0045] The process of inserting the eccentric inclined shaft 22 into the mounting seat 21 is as follows: use a jack to support the fixing device 1, so that the trolley 4 is separated from the ground rail, and the eccentric inclined shaft 22 is inserted from one end of the second shaft hole on the mounting seat 21 while rotating. Because the axes of the two shaft heads of the eccentric inclined shaft 22 coincide, the mounting seat 21 is rotated counterclockwise or clockwise along its vertical axis during the process of the eccentric inclined shaft 22 rotating into the mounting seat 21, thereby realizing the deviation correction of the mounting seat 21, that is, the four ground rail wheels 42 are driven to be arranged in a straight line through the rotation of the balance beam 3.

[0046] The deviation correction device 2 of the present invention can accurately correct the straight line arrangement of multiple rail wheels 42 by only inserting the eccentric inclined shaft 22 into the mounting seat 21, and is easy to operate and has a simple structure.

[0047] It should be understood that the operating mechanism is a part of the crane, and a crane using the operating mechanism with the function of correcting the deviation of the balance beam 3 is also within the protection scope claimed by the present utility model.

[0048] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
