Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.

Referring to fig. 1-9, an automobile die gantry crane comprises a gantry 5, wherein a cart running mechanism 7 is arranged at the bottom of the gantry 5, a gantry accessory 4 is fixed on the gantry 5, a trolley 1 capable of sliding along the gantry accessory 4 is arranged on the gantry 5, the trolley 1 is connected with a lifting appliance 8 through a steel wire rope system 2, and four hooks 6 are arranged on the lifting appliance 8.

As shown in fig. 6-8, the lifting appliance 8 comprises an X-axis track 81, two sliding seats 82 capable of sliding along the X-axis track 81 are arranged on the X-axis track 81, an X-axis motor 91 is arranged on the lifting appliance 8, an output shaft of the X-axis motor 91 is connected with a bidirectional screw rod 92, spiral directions of two ends of the bidirectional screw rod 92 are opposite, each end part of the bidirectional screw rod 92 is uniformly connected with one sliding seat 82 through threads, and when the X-axis motor 91 is started, the two sliding seats 82 are far away from or near to each other simultaneously.

As shown in fig. 6 to 9, two hanger bars are provided on the slider 82 along the Y-axis direction: the outer end parts of the hanger rod A84 and the hanger rod B85 are respectively fixed with a hanger 6, a Y-axis motor 94 is fixed on the sliding seat 82, an output shaft of the Y-axis motor 94 is connected with a driving sprocket 95, racks meshed with the driving sprocket 95 are respectively fixed on the two hanger rods, the meshing point of the racks of the hanger rod A84 and the driving sprocket 95 is an M point 96, the meshing point of the racks of the hanger rod B85 and the driving sprocket 95 is an N point 97, and the connecting line of the M point 96 and the N point 97 passes through the axle center of the driving sprocket 95. Thus, when the drive sprocket 95 rotates counterclockwise, the hanger bar a84 and the hanger bar B85 are simultaneously away from each other; conversely, when the drive sprocket 95 rotates clockwise, the hanger bar a84 and the hanger bar B85 approach at the same time.

As shown in fig. 1-2, in order to prevent shaking, two rigid guide posts 3 are arranged on the lifting appliance 8, two positioning holes 11 are arranged on the trolley 1, and when the lifting appliance 8 is positioned at a high position, the rigid guide posts 3 penetrate through the positioning holes 11.

The specific working process is as follows:

when in operation, the operation of the automobile die portal crane is the same as that of the prior art, and the difference is that:

if the positions of the four hooks 6 need to be adjusted, the X-axis motor 91 is started first, the two sliding seats 82 are far away from or close to each other simultaneously, the sliding seats 82 drive the hook rods and the four hooks 6 to move synchronously, and the positions of the four hooks 6 in the X-axis direction are adjusted. Referring to fig. 6, the hook 6 corresponding to reference numeral 61 is located distally and the hook 6 corresponding to reference numeral 62 is located proximally.

Secondly, when the driving chain wheel 95 rotates clockwise, the hook rod A84 and the hook rod B85 are simultaneously close to or far away from each other, and the hook rod drives the four hooks 6 to synchronously move, so that the positions of the four hooks 6 in the Y-axis direction are adjusted. Referring to fig. 7, the hook 6 corresponding to reference numeral 63 is located distally and the hook 6 corresponding to reference numeral 64 is located proximally.

After adjustment, the distances from the four hooks 6 to the lifting appliance 8 are unchanged, the lifting stability is not affected, and meanwhile, the distances between the four hooks 6 are adapted to a new automobile die (workpiece), so that the operation is convenient.

It should be noted that: after the crane is lifted in situ, when the lifting appliance 8 is positioned at a high position, the rigid guide column 3 penetrates through the positioning hole 11, the lifting appliance 8 is subjected to rigid constraint at the moment, and when the crane moves, the lifting appliance 8 and a workpiece can be kept stable and safer.

See the prior art for others.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
