Description

Technical Field

[0001] This utility model relates to the field of ground beam drive technology, and in particular to a ground beam drive structure. Background Technology

[0002] Gantry cranes are a type of bridge crane, also known as portal cranes, and are mainly used for loading and unloading cargo and bulk materials in outdoor freight yards and material yards. Gantry cranes are characterized by high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards. Their metal structure resembles a portal frame, with two legs installed under the main beam, allowing them to travel directly on ground-level tracks. The main beam may have cantilever beams extending outwards at both ends.

[0003] The existing technology, application number CN2017108208904, is a trackless gantry crane that can be raised and lowered. The existing technology uses a bevel gear for transmission. This transmission method is inconvenient to process, assemble and debug, and the transmission noise is large. The existing chain belt transmission has low efficiency and poor torque transmission.

[0004] Therefore, a ground beam drive structure needs to be designed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a ground beam drive structure to overcome the aforementioned shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A ground beam drive structure includes a geared motor, a drive gear driven by the geared motor, a transmission assembly connected to the drive gear, and wheels mounted on both sides of the transmission assembly. The structure is characterized by: a wheel housing being provided at the drive end of the geared motor, the wheel housing enclosing the drive end of the geared motor; the drive gear being mounted on the side of the geared motor via a drive shaft; the transmission assembly being placed within the wheel housing; and the transmission assembly including a drive axle mounted on both sides of the wheel housing via bearings, a large gear mounted on the drive axle and meshing with the drive gear, and the shaft portion of the drive axle having a hexagonal structure.

[0008] Preferably, the drive end of the geared motor is located on the side.

[0009] Preferably, the large gear has an internal hexagonal slot.

[0010] Preferably, two sets of retaining rings are also provided on the drive shaft, with the retaining rings respectively placed on both sides of the large gear.

[0011] Preferably, an outer cover is provided on the outside of the bearing, and the outer cover is fixed by a nut in conjunction with the wheel housing.

[0012] Preferably, grooves for mounting wheels are provided at both ends of the drive wheel axle, and strip-shaped protrusions are provided on the grooves, while a strip-shaped groove is provided on the inner rim of the wheel.

[0013] Preferably, the baffle is fixed to the shaft end of the drive wheel shaft by a nut.

[0014] The beneficial effects of this utility model are: the hexagonal structure is used for transmission, which is more efficient in transmitting torque compared with the prior art. At the same time, the gear transmission method is convenient for processing and assembly, with high efficiency and low noise. Attached Figure Description

[0020] Reference Figures 1 to 4 A ground beam drive structure includes a geared motor 1, a drive gear 2 driven by the geared motor, a transmission assembly connected to the drive gear, and wheels 3 mounted on both sides of the transmission assembly.

[0021] To facilitate the installation of the transmission components and wheels, a wheel housing 4 is also provided at the drive end of the geared motor, and the wheel housing is provided to enclose the drive end of the geared motor.

[0022] The drive end of the geared motor is located on the side, and the drive gear is mounted on the side of the geared motor via the drive shaft 13;

[0023] The transmission assembly is placed in the wheel housing 4. The transmission assembly includes a drive wheel shaft 5, which is mounted on the two wheel housings 4 on both sides by bearings, and a large gear 6, which is placed on the drive wheel shaft and meshes with the drive gear.

[0024] The shaft of the drive shaft wheel 5 has a hexagonal structure, and the large gear 6 installed in conjunction with it also has an internal hexagonal slot; the hexagonal structure is more effective in transmitting torque than the flat key.

[0025] In order to facilitate the installation of the large gear, two sets of retaining rings 7 are also provided on the drive shaft 5. The retaining rings are respectively placed on both sides of the large gear to restrict the large gear.

[0026] To facilitate installation and prevent bearing slippage, an outer cover 8 is provided on the outside of the bearing, and the outer cover is fixed by a nut in conjunction with the wheel box 4.

[0027] To facilitate the installation of the wheel 3 and prevent the wheel from slipping and affecting normal use, grooves 9 for mounting the wheel are respectively provided at both ends of the drive wheel axle 5, and strip-shaped protrusions 10 are provided on the grooves. The inner ring of the wheel is provided with a strip-shaped groove, and the strip-shaped groove of the wheel is fitted with the strip-shaped protrusions 10 to ensure that the wheel will not slip during rotation.

[0028] Since it is placed in a groove, the diameter of the groove is relatively small. The side of the wheel is blocked by the other side with a larger diameter, which serves as a limit. Similarly, a baffle 11 is provided on the outside, and the baffle 11 is fixed to the shaft end of the drive wheel axle 5 by a nut, thereby limiting the other end and preventing it from moving left and right during rotation.

[0029] For ease of assembly, quick axis positioning, and convenient replacement later, a calibration cone 12 is provided on the side of the wheel housing. The reducer output shaft has a conical hole. The calibration cone ensures the installation axis and guarantees normal gear meshing. After adjusting the axis, the calibration cone is removed and stored in its original position. When replacing gears, the calibration cone is used again to adjust the gear meshing to ensure normal operation.

[0030] The advantages of this utility model are that the technical solution adopts a hexagonal structure for transmission, which has higher torque transmission efficiency compared with the prior art. At the same time, the gear transmission method facilitates processing and assembly, resulting in high efficiency and low noise.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
