[0002] As an auxiliary transport device in coal mines, monorail cranes offer advantages such as strong safety, high driving force, adaptability, small footprint, and high transport efficiency. They are widely used in confined spaces such as tunnels and mines and are suitable for most coal mines in my country. Monorail cranes are typically powered by explosion-proof diesel engines or batteries and travel along a track suspended above a tunnel or mine shaft.

[0003] The monorail locomotive consists of multiple drive units, which provide driving and braking forces for the locomotive. Figure 5 As shown, current connections utilize connecting rods, with the drive unit's connecting seats located on the front and rear sides of the drive unit, typically made from forgings. These seats are located outside the drive unit's running wheels. To reduce lateral forces generated by track curves and large deviations, the connecting rod length is typically 1000mm. When a locomotive has a large number of drive units, the overall locomotive length increases accordingly, resulting in poorer airflow through the airlock. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0021] In the prior art, a monorail crane includes a plurality of driving parts, some of which are connected adjacently, and some of which are connected with a lifting beam between them. The lifting beam plays the role of lifting cargo, such as Figures 1 to 5 As shown, the utility model is a monorail crane drive unit connection structure, in which adjacent monorail crane drive units 3 are connected by an internal connection component 1, and the lifting beam and the drive unit 3 are connected by an external connection component 2.

[0022] like Figure 2 As shown, the driving part 3 includes a driving part frame 31, and the front and rear ends of the driving part frame 31 are both provided with horizontal pin shaft holes 32 running through left and right. The front and rear ends of the driving part frame 31 are also provided with anti-sway pin shaft holes 33 running through left and right.

[0023] like Figure 3 As shown, the internal connection component 1 includes a male connection member 12 and a female connection member 11 arranged in front and back, the male connection member 12 includes a cylindrical section and a flat plate section fixed to the rear end of the outer circle of the cylindrical section, the flat plate section and the cylindrical section are integrally processed and formed, and the front end of the male connection member 12 is hinged to the front monorail crane drive unit 3 through a cross pin shaft 13, and the cross pin shaft 13 passes through the cylindrical section and is inserted into the cross pin shaft hole 32 of the front monorail crane drive unit 3.

[0024] The female connector 11 also includes a flat section at the front and a cylindrical section at the rear. The rear end of the male connector 12 is hinged to the front end of the female connector 11 via a vertical pin 14. Specifically, the front end of the flat section of the female connector 11 has a receiving slot, into which the rear end of the male connector 12 is inserted. The vertical pin 14 vertically passes through the male connector 12 and the female connector 11, and is axially positioned by a cotter pin 15.

[0025] The rear end of the female connector 11 is hinged to the rear monorail crane drive unit 3 through a transverse pin shaft 13. The transverse pin shaft 13 passes through the cylindrical section at the rear end of the female connector 11 and is inserted into the transverse pin shaft hole 32 of the rear monorail crane drive unit 3.

[0026] The monorail crane drive unit 3 utilizes an articulated, split structure with two sections and a pinned connection. This allows for both horizontal and vertical yaw, meeting trafficability requirements. The internal connecting assembly 1 is 500-800mm shorter than a tie rod connection.

[0027] The external connection component 2 includes an external connection part, which includes an external connection block 21 and an external connection seat 22 fixed to one end of the external connection block 21. The end of the external connection block 21 away from the external connection seat 22 is hinged to the monorail crane drive unit 3 through a cross pin shaft 13, and the cross pin shaft 13 is inserted into the cross pin shaft hole 32 of the monorail crane drive unit 3.

[0028] The end of the external connection seat 22 away from the external connection block 21 is hinged to the lifting beam through the vertical pin shaft 14. Figure 4 As shown, the external connection seat 22 is a horizontal U-shaped structure. The connection part on the lifting beam is located in the U-shaped structure, and the vertical pin shaft 14 passes through the connection part.

[0029] The monorail crane drive unit 3 has an anti-sway pin hole 33 formed in the drive unit frame 31, and an anti-sway pin 23 is provided on the external connector to fit within the anti-sway pin hole 33. The anti-sway pin 23 is inserted into the anti-sway pin hole 33 of the monorail crane drive unit 3 and is installed only when needed. The anti-sway pin 23 cooperates with the cross pin 13 to provide a position limit.

[0030] To improve the versatility of the drive unit frame 31, each drive unit frame 31 has transverse pin holes 32 and anti-sway pin holes 33 at both the front and rear ends. Therefore, a connecting seat is no longer provided within the monorail crane drive unit 3. However, due to the small size of the monorail crane drive unit 3 and the large size of the lifting beam, the connection point between the external connecting assembly 2 and the lifting beam is significantly lower than the connection point between the external connecting assembly 2 and the monorail crane drive unit 3. Therefore, the end of the external connecting block 21 near the external connecting seat 22 is bent downward. At this point, the upper end surface of the external connecting seat 22 is lower than the upper end surface of the external connecting block 21.

[0031] Therefore, the external connection component can be connected to various other components, and the traction center height and connection size can be unified through the external connection component.

[0032] Of course, the above description is not limited to the above examples. The technical features not described in the present invention can be achieved through or by adopting existing technologies, and will not be repeated here. The above embodiments and drawings are only used to illustrate the technical solution of the present invention and are not limitations of the present invention. The present invention is described in detail with reference to the preferred implementation methods. Ordinary technicians in this field should understand that the changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention do not depart from the purpose of the present invention and should also fall within the scope of protection of the claims of the present invention.
