Description

Technical Field

[0001] This utility model relates to the field of gantry milling machine installation technology, and in particular to a balancing device for gantry milling machine installation. Background Technology

[0002] As a heavy-duty precision machining equipment, the gantry milling machine's core component, the gantry frame, is large in size and has a concentrated weight. During installation, commissioning, and maintenance, the gantry frame must be accurately placed in the predetermined position on the installation platform using hoisting equipment. Furthermore, it must maintain stability and balance during the lifting, adjustment, and position calibration stages to avoid component collisions, installation accuracy deviations, or even safety accidents caused by shifts in the center of gravity or accidental shaking.

[0003] The existing installation method for gantry milling machines involves first using a crane to lift the gantry frame, then roughly moving it to the predetermined installation position. Afterward, manual labor is required, with the assistance of the crane, to move the gantry frame to the designated point before installation. This method sometimes necessitates manual pushing of the bottom of the gantry frame, lifted by the crane, to finely adjust its installation position. This method suffers from poor precision; furthermore, if the gantry frame slips during installation, it can endanger the safety of the workers. Utility Model Content

[0014] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0015] like Figures 1-5 As shown, this utility model discloses a balancing device for mounting a gantry milling machine, including two symmetrically arranged balancing guardrail carriages 1, a fixing mechanism 2, a connecting mechanism 3, and a limiting mechanism 4; The bottom of the balance guardrail vehicle 1 is fixed with multiple rotatable wheels 5; The fixing mechanism 2 is installed on the balance guardrail vehicle 1 and is used to limit the gantry 6; The two ends of the connecting mechanism 3 are fixedly connected to the two balance guardrail vehicles 1 respectively, and are used to connect the two balance guardrail vehicles 1; The limiting mechanism 4 is inserted into the balance guardrail vehicle 1 and is used to fix the balance guardrail vehicle 1 at a predetermined position on the installation platform 7.

[0016] Furthermore, the balance guardrail vehicle 1 includes a chassis 11, a guardrail 12, and an openable protective door 13; A clearance opening 111 is provided in the middle of the chassis 11, and the gantry 6 is installed in the clearance opening 111 in a height-adjustable manner. The guardrail 12 is vertically fixed to the top of the chassis 11. The guardrail 12 is set on the outer periphery of the clearance opening 111. The three guardrails 12 are fixedly connected in sequence and surround the three sides of the clearance opening 111. One end of the openable protective door 13 is rotatably connected to the protective railing 12, and the other end is fixedly connected to another protective railing 12 by the first bolt 14.

[0017] Furthermore, extension plates 15 are fixedly provided on both opposite side walls of the chassis 11.

[0018] Furthermore, each balance guardrail vehicle 1 is equipped with two symmetrically arranged fixing mechanisms 2, each fixing mechanism 2 including a screw 21, a handwheel 22 and an anti-slip compression plate 23; Screw 21 is threadedly connected to guardrail 12; The handwheel 22 is coaxially and fixedly connected to one end of the screw 21, and the handwheel 22 is located on the outside of the balance guardrail vehicle 1; The anti-slip extrusion plate 23 is rotatably connected to the other end of the screw 21, and the anti-slip extrusion plate 23 abuts against the gantry 6.

[0019] Furthermore, the connecting mechanism 3 includes a slot 31 and a connecting plate 32; Each balance guardrail vehicle 1 has an upward-facing slot 31 fixed on its guardrail 12; The two ends of the connecting plate 32 are respectively inserted into the two slots 31 and fixed in the slots 31 by the second bolt 33.

[0020] Furthermore, the limiting mechanism 4 includes a limiting rod 41, the rod body of which is inserted into the extension plate 15, and the bottom of the limiting rod 41 is inserted into the mounting platform 7.

[0021] In use, first use a crane to lift the gantry frame 6. Once the gateposts are basically stable and no longer wobbling, move a balance guardrail cart 1 with an openable protective door 13 in the open position to the vicinity of one of the gateposts. Then push the balance guardrail cart 1 to install the gatepost inside the guardrail 12 and close the openable protective door 13. Turn the handwheel 22, which drives the screw 21 to rotate. The screw 21 drives the anti-slip compression plate 23 to move until the anti-slip compression plate 23 rests against the side wall of the gatepost. Then adjust the other handwheel 22 in the same way so that the two anti-slip compression plates 23 clamp the two opposite side walls of the gatepost. Obviously, the two handwheels 22 can also be adjusted simultaneously. At this point, the fixing of one gatepost is completed. Then fix the other gatepost in the same way. After fixing, respectively, insert the two ends of the connecting plate 32 into the two slots 31, and fix the connecting plate 32 in the slots 31 with the second bolt 33.

[0022] Then, manually pulling the balance guardrail cart 1 will move the gantry 6. Simultaneously, a crane is needed to assist in the movement, ensuring the crane provides upward tension to the gantry 6. Once the balance guardrail cart 1 reaches the predetermined position, the limiting rod 41 is passed through the extension plate 15 and inserted into the installation platform 7, thus limiting the balance guardrail cart 1. The handwheel 22 is then turned again to create a small gap between the anti-slip compression plate 23 and the gantry. The crane is adjusted to slowly lower the gantry 6, placing it in the installation position. Installation of the gantry 6 can then proceed. During the lowering of the gantry 6, the anti-slip compression plate 23 maintains the balance of the gantry, preventing swaying and further preventing displacement.

[0023] A rubber pad can be fixed on the side of the anti-slip extrusion plate 23 near the gantry 6 to achieve an anti-slip effect.

[0024] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
