Description

Technical Field

[0001] The present invention relates to the technical field of lifting equipment processing, and in particular to a processing device for a slewing mechanism mounting seat of a gantry crane turntable. The present invention also relates to a processing method for a slewing mechanism mounting seat of a gantry crane turntable. Background Art

[0002] The turntable of the portal crane carries the column assembly and the boom assembly, and can rotate 360° driven by the slewing mechanism, allowing its operating coverage to be wider.

[0003] At present, the turntable of the gantry crane is large in size and heavy in weight, and the machining position of the turntable structure is difficult to achieve with standard general-purpose machine tools. The installation of the slewing mechanism on the crane turntable is generally completed by upper and lower mounting rings and welding. The upper and lower mounting rings are connected to the upper and lower panels of the turntable structure, wherein the slewing mechanism is set on the upper mounting ring by bolts, and the lower mounting ring is set on the gear end of the slewing mechanism to support it, and the lower mounting ring is connected to the turntable structure by welding. However, due to the installation of the upper and lower mounting ring areas of the upper and lower panels of the turntable structure, it is very easy to have obvious welding deformation after the welding of the turntable structure, resulting in uneven surface. Due to the overall structural reasons, it is difficult to achieve mechanical processing, making it difficult to level and adjust the position of the slewing mechanism during installation. As a result, after the slewing mechanism is installed, when the crane is first used or after a short period of use, there will be a large abnormal noise at the slewing mechanism or abnormal wear on the slewing pinion and the slewing bearing tooth surface, which seriously affects the safe and normal operation of the equipment.

[0004] Therefore, how to provide a gantry crane turntable slewing mechanism mounting seat processing equipment, which can make the slewing mechanism on the turntable panel installed flat, facilitate the accurate adjustment of the slewing mechanism, and save preparation time, has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0017] A processing device for the mounting seat of the slewing mechanism of a portal crane provided by the present invention includes: a traveling mechanism; a first lifting assembly disposed on the traveling mechanism; a support crossbeam disposed on the first lifting assembly; the upper end surface of the support crossbeam abuts against the mounting flange surface of the slewing bearing of the slewing mechanism; a fastening mechanism disposed on the support crossbeam and connecting the support crossbeam and the mounting flange of the slewing bearing; a column mechanism disposed on the support crossbeam and movably connected to the support crossbeam; a cantilever beam mechanism disposed at the end of the column mechanism and movably connected to the column mechanism; a counterweight mechanism disposed at one end of the cantilever beam mechanism; and a power head assembly disposed at the other end of the cantilever beam mechanism and movably connected to the cantilever beam mechanism.For the processing equipment of the turntable slewing mechanism mounting seat disclosed in the present invention, its main structure is composed of the traveling mechanism, the first lifting assembly, the support crossbeam, the fastening mechanism, the column mechanism, the cantilever beam mechanism, the counterweight mechanism, and the power head assembly; among them, the support crossbeam is used for positioning and leveling. A fastening mechanism is arranged on the support crossbeam. Through the fastening mechanism, the support crossbeam can be connected to the slewing bearing mounting flange on the turntable structure, so that it is fixed on the plane of the slewing bearing mounting flange. At this time, the upper end face of the support crossbeam is in flat contact with the plane of the slewing bearing mounting flange, enabling the processing equipment to be based on the processed plane of the slewing bearing mounting flange without leveling the turntable structure, saving preparation time; below the support crossbeam, the first lifting assembly and the traveling mechanism are arranged. The first lifting assembly is installed at both ends of the support crossbeam, and the traveling mechanism is arranged at the bottom end of the first lifting assembly. The traveling mechanism can be used to move the support crossbeam below the plane of the slewing bearing mounting flange, and then through the first lifting assembly, the position of the support crossbeam is adjusted to make it move vertically up and down, enabling the upper end face of the support crossbeam to be in contact with the plane of the slewing bearing mounting flange; secondly, on the upper end face of the support crossbeam, the column mechanism is vertically installed. The column mechanism is slidably arranged on the support crossbeam and can move on the support crossbeam and can be locked in position after determining the processing position; and the cantilever beam mechanism is installed on the column mechanism. The cantilever beam mechanism is supported by the column mechanism and is connected to the column mechanism, and can rotate around the column mechanism and move on its axis, enabling the power head assembly to move to the processing area; at both ends of the cantilever beam mechanism, the power head assembly and the counterweight mechanism are respectively arranged. The counterweight mechanism is used to balance the power head assembly to ensure the stable operation of the power head assembly, and the power head assembly is used for machining the installation area of the turntable slewing mechanism, that is, the machining of the plane of the slewing mechanism mounting seat, to ensure the adjustment of the slewing mechanism. Among them, the power head assembly is slidably arranged on the cantilever beam mechanism and can move along the axis of the cantilever beam mechanism. When machining the plane of the mounting seat, according to the range of the machining area, the cantilever beam mechanism rotates around the column mechanism. At the same time, the power head assembly moves in the axial direction of the cantilever beam mechanism, and then combined with the power head assembly rotating itself to make it move in the vertical direction, the power head assembly is moved to the processing area, and the precision machining operation of the plane of the slewing mechanism mounting seat can be conveniently completed. Thus, it can be seen that the technical solution provided by the present invention, compared with the prior art, can make the slewing mechanism on the turntable panel installed flat, facilitating the accurate adjustment of the slewing mechanism and saving preparation time.

[0027] As Figure 4 , Figure 5 shown, Figure 4 FIG. is a schematic structural diagram of a turntable structure 9 in the prior art, Figure 5 FIG. is an installation schematic diagram of a slewing mechanism 10 in the turntable structure 9. As can be seen from the figure, for the installation of the slewing mechanism 10 in the crane turntable, generally, through the upper mounting ring 11, the lower mounting ring 12 and the way of cooperative welding, it is respectively connected to the upper turntable panel 904 and the lower turntable panel 905 of the turntable structure 9. Among them, the slewing mechanism 10 is arranged on the upper mounting ring 11 through bolts, and the lower mounting ring 12 is sleeved on the gear end of the slewing mechanism 10 to support it and abuts against the lower mounting ring mounting surface 13, and the lower mounting ring 12 is welded and connected to the turntable structure 9. However, due to the fact that the welding in the mounting ring area of the upper turntable panel 904 and the lower turntable panel 905 is extremely likely to cause large deformation, resulting in uneven plane, when the slewing mechanism 10 is installed, it is difficult to level and align the position adjustment, resulting in large abnormal noises at the slewing mechanism 10 or abnormal wear between the slewing pinion and the slewing bearing tooth surface after the slewing mechanism 10 is installed and used, affecting the safe and normal operation of the equipment. Therefore, the present invention discloses a processing device for the mounting seat of the slewing mechanism of a portal crane, aiming to provide a processing device that can ensure the flat installation position of the slewing mechanism 10 on the turntable panel and facilitate the accurate adjustment of the slewing mechanism 10.
