Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an insulating frame device for a traveling overhead crane or trolley. Background Art

[0002] Overhead cranes are lifting machines primarily used for vertical lifting and horizontal transport of heavy objects. They are widely used in construction sites, factories, ports, and other fields, offering advantages such as simple construction, high lifting capacity, reduced physical labor for workers, and minimal floor space. With adjustments to production processes in factory electrolysis workshops, the double-girder overhead cranes in these workshops are subject to the high temperatures, dust, and high magnetic fields of electrolysis. When the insulating running wheels overlap the trolley frame, the overall insulation structure of the trolley becomes unstable, leading to frequent trolley insulation failures and thus affecting workshop efficiency. Once a trolley insulation failure occurs, the insulation layer near the trolley running wheels must be inspected piecemeal. Due to the limited space and time required for inspection, this often results in long downtime, significantly impacting the daily safety and productivity of the electrolysis workshop. The insulation monitoring equipment used is unable to monitor insulation performance in real time online. The current trolley insulation structure is insufficient to meet the normal operational requirements of the electrolysis workshop, and equipment operation also presents numerous safety risks. Therefore, a trolley running frame assembly with excellent insulation performance is key to improving workshop efficiency. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1 to 4As shown, the utility model is an insulating frame device for a traveling overhead crane trolley, comprising a trolley frame body 2 and a trolley frame chassis 1, wherein the trolley frame body 2 and the trolley frame chassis 1 are connected by a plurality of insulating height adjustment devices 3. In this embodiment, the number of insulating height adjustment devices 3 is preferably 4, and the lower end of the insulating height adjustment device 3 is an insulating layer kit structure 4, which is welded to the trolley frame chassis 1, and the upper end of the insulating height adjustment device 3 is welded to the trolley frame body 2, wherein the insulating layer kit structure 4 is a multi-layer insulating plate connected by a flange structure, and the insulating plates in the insulating layer kit structure 4 are at least two layers. Preferably, the insulating plates in the insulating plate kit structure of this embodiment are three layers, namely, from bottom to top, the first insulating plate 41, the second insulating plate 42, and the third insulating plate 43. By improving the insulating plate kit structure, the number of insulating plates is increased while the contact area is increased, thereby greatly improving the insulation performance between the trolley frame body and the trolley frame chassis.

[0026] like Figures 2-4 As shown, the lower surface of the first insulating plate 41 is bonded with a fastening steel plate 1 48, and the upper surface of the third insulating plate 43 is bonded with a fastening steel plate 2 49. Bolts 81 pass through the fastening steel plate 1 48, the insulation layer assembly structure 4, and the fastening steel plate 2 49 before being connected to nuts 82. A first bolt insulation layer 44 and a second bolt insulation layer 45 are provided between the bolts 81 and the fastening steel plate 1 48, and a third bolt insulation layer 46 and a fourth bolt insulation layer 47 are provided between the nuts 82 and the fastening steel plate 2 49. The two additional insulation layers, respectively, between the bolts 81 and the fastening steel plate 1 48, and between the nuts 82 and the fastening steel plate 2 49, further improve the insulation performance of the insulation height adjustment device and reduce the frequency of failures. The insulation height adjustment device 3 also includes a height adjustment kit 31, a first fastening lug 34, a second fastening lug 35, an adjustment bolt 32, and a second adjustment bolt 33. The bottom of the height adjustment kit 31 is provided with a base. The first fastening lug 34 and the second fastening lug 35 are fixedly connected to opposite sides of the height adjustment kit 31. The first adjustment bolt 32 passes through the first fastening lug 34 and is fixedly connected to the base of the height adjustment kit 31 via a threaded connection. The second adjustment bolt 33 passes through the second fastening lug 35 and is fixedly connected to the base of the height adjustment kit 31 via a threaded connection. During use, the height adjustment kit 31 can be adjusted to the desired height, and then the first and second adjustment bolts 32, 33 can be tightened. The insulation height adjustment device 3 at the four corners can be adjusted to stabilize the center of gravity of the trolley frame, ensuring stable travel.

[0027] like Figure 1 、 2As shown in Figures 5 and 6, the trolley chassis 1 has an H-shaped structure, with fixed wheels 5 positioned below the four corners. Preferably, the fixed wheels 5 in this embodiment are edgeless wheels, effectively addressing the problem of the trolley wheels gnawing at the track. Adjustable track brushes 6 are located on the outer sides of the fixed wheels 5 in the direction of travel. The bristles are made of steel and are secured and adjusted by retaining pins 61. During operation, the adjustable track brushes effectively prevent the brushes from getting stuck on the running wheels. The height of the track brushes can also be adjusted by adjusting the retaining pins according to wear and tear, more thoroughly cleaning dirt from the track surface and reducing its impact on insulation performance. Furthermore, a horizontal wheel set 7 is provided on one side of the fixed wheels 5. These horizontal wheel sets 7 are located inward of two adjacent fixed wheels 5 whose directions of travel overlap. Two sets of horizontal wheel sets 7 are provided, one on each side of the overhead crane trolley's direction of travel. Adjustment of the horizontal wheel sets during trolley operation improves the trolley's stability.

The insulation height adjustment device can be adjusted accordingly according to the actual use height of the trolley on site, and then locked by adjusting bolt 1 32 and adjusting bolt 2 33 to ensure the stability of the trolley during operation. Furthermore, the adjustable track brush 6 is used to clean various dirt on the trolley track, which also reduces the impact of dirt on the insulation performance of the trolley during operation. The improvements of the utility model significantly improve the insulation performance of the overhead crane trolley travel frame device in harsh environments, reduce the failure rate, improve workshop operation output, and increase economic benefits.
