[0014] The following detailed description of the embodiments of the present utility model is given on the premise of the technical solution of the present utility model, and the detailed implementation manners and specific operation processes are provided, but the protection scope of the present utility model is not limited to the following embodiments.
[0015] It should be noted that in the description of the present utility model, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
[0016] In the description of the present utility model, unless otherwise clearly specified and defined, the terms "connected" and "connected to" that may appear should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0017] As Figures 1-5 shown, the large-tonnage hoist drum assembly auxiliary tooling of the present utility model includes a support frame 1, a jack 2 (which can also be a hydraulic cylinder) arranged on the support frame 1, a support cross beam 3, and an anti-slip seat 4 arranged on the support cross beam 3. The support frame 1 includes a bottom plate 1.1, a support column 1.2 welded to the bottom plate 1.1, and a top plate 1.3 welded to the top of the support column 1.2. The bottom plate 1.1 can be fixed to the steel plate on the workshop floor by bolts, thereby achieving fixation; wherein, a lower connecting plate 1.4 is welded between the lower part of each support column 1.2 and the bottom plate 1.1, and an upper connecting plate 1.5 is welded between the upper part of each support column 1.2 and the top plate 1.3. The two support columns 1.2 are connected by a reinforcing diagonal brace 1.6 (which can be made of angle steel) to improve the stability and support performance of the support frame 1 and further meet the support requirements of the drum.
[0018] There are two jacks 2, which are fixedly installed on the top plate 1.3 of the support frame 1. The support cross beam 3 is fixed to the power output end of the jack 2. During actual assembly, the jack 2 can drive the installation end of the drum to rise and fall through the support cross beam 3, thereby achieving centering adjustment, reducing the assembly difficulty, and improving the assembly efficiency; wherein, the support cross beam 3 can be made of I-beam. To improve the structural strength of the support cross beam 3, reinforcing rib plates 5 are welded at intervals on the I-beam.
[0019] There are two anti-slip seats 4, and the two anti-slip seats 4 are symmetrically and fixedly installed on the support cross beam 3. The anti-slip seat 4 has an arc-shaped support surface that cooperates with the drum (to increase the friction force, a rubber pad can be installed on the arc-shaped support surface). The two arc-shaped support surfaces are arranged opposite to each other to limit the drum by the two arc-shaped support surfaces, and the drum can be effectively prevented from rotating during the assembly process. Among them, during actual processing, the anti-slip seat 4 can be processed from I-beam, and the web of the I-beam is cut into an arc-shaped structure that cooperates with the drum during processing.
[0020] During assembly, first place the frame of the hoist on the ground and level the reference surface; draw the longitudinal and transverse centerlines of the drum and the reducer on the surface of the frame; fix the present utility model on the workshop floor (near the reducer), and its support centerline is located on the central axis of the drum (i.e., the transverse centerline F3) drawn on the frame. Lift the drum F1 with a lifting device and use bolts to fix its bearing end (i.e., Figure 1The right end (in the figure) is fixed on the support F4 of the right rack, and the installation end of the present invention (i.e., the end assembled with the reducer, that is, Figure 1 the left end in the figure) is supported by the present invention, and the installation end of the drum F1 is jacked up by a certain height by the jack 2; the reducer F2 (with a coupling) is hoisted onto the left rack, and the jack 2 is adjusted to drive the installation end of the drum to descend, so that the central axis of the drum F1 is in a horizontal position, ensuring that it coincides with the vertical and horizontal center lines drawn on the surface of the rack. Connect the couplings on the drum F1 and the reducer F2 together, and the assembly of the drum F1 and the reducer F2 can be realized. The present invention can flexibly adjust the drum, thereby quickly determining the center line of the drum, reducing the alignment difficulty, and improving the assembly efficiency.
[0021] Finally, it should be emphasized that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or make equivalent replacements for some of the technical features. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
