AI Technical Summary
The existing crane's main crossbeam connection structure is located at the bottom, which restricts the track, prevents the electric hoist from moving to corners, and results in large stroke errors, failing to meet usage requirements.
Design an inverted overhead crane with an inverted main beam that is connected to the end beams via connecting units. The main beam has notches at both ends to increase its range of motion.
This allows the electric hoist to be moved to the corner of the main beam, expanding the travel range of the crane and meeting usage requirements.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to the technical field of travelling crane, and relates to a hanging type travelling crane. BACKGROUND
[0002] The travelling crane is an indispensable structure in the factory, which is used for the carrying of objects, but in the actual use process, the connecting structure of the main beam is generally arranged at the lower part, which leads to the limitation of the track on the beam, and the electric hoist on the travelling crane cannot be moved to the corner, so that the actual stroke is limited, and the stroke error is generally about 1m, thereby failing to meet the use requirement. SUMMARY
[0003] The utility model discloses a travelling crane that solves the above problems.
[0004] The utility model discloses a hanging type travelling crane, which comprises a travelling crane main body, characterized in that the travelling crane main body comprises a plurality of supporting frames, a plurality of connecting plates, a main beam and two end beams, every two of the supporting frames form a supporting foot structure, the two ends of the connecting plate are connected with the corresponding supporting frames in the supporting foot structure respectively, the two end beams are connected with the connecting plate through a connecting unit, and the main beam is arranged below the two end beams and connected with them.
[0005] In the above-mentioned hanging type travelling crane, the connecting unit comprises two connecting blocks, the connecting blocks are connected with the connecting plate through a plurality of studs, and the lower end of the connecting block is connected with the end beam.
[0006] In the above-mentioned hanging type travelling crane, the two ends of the main beam are provided with notched grooves for the installation of the corresponding end beams.
[0007] Compared with the prior art, the hanging type travelling crane has a larger moving range than the conventional one, so that the electric hoist can be moved to the corner of the main beam. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 It is the schematic diagram of the three-dimensional structure in the hanging type travelling crane.
[0009] In the drawing, 1 is a supporting frame, 2 is a connecting plate, 3 is a main beam, 4 is an end beam, and 5 is a connecting block. DETAILED DESCRIPTION
[0010] The following is a specific embodiment of the utility model and a further description of the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0011] For example, Figure 1As shown, the upside-down crane includes a crane main body, the crane main body includes a plurality of supporting frames 1, a plurality of connecting plates 2, a main beam 3 and two end beams 4, every two of the plurality of supporting frames 1 form a supporting leg structure, the two ends of the connecting plate 2 are connected with the corresponding supporting frames 1 in the supporting leg structure respectively, the two end beams 4 are connected with the connecting plate 2 through connecting units, the main beam 3 is arranged below the two end beams 4 and connected with the same, the connecting unit includes two connecting blocks 5, the connecting blocks 5 are connected with the connecting plate 2 through a plurality of studs, the lower end of the connecting block 5 is connected with the end beam 4, the two connecting blocks 5 are respectively located on the two end faces of the connecting plate 2, and the two end portions of the main beam 3 are both provided with a notch groove for facilitating installation of the corresponding end beam 4.
[0012] The specific embodiments described herein merely exemplify the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
