[0023] Example 1,

[0024] Combination Figures 1 to 4As shown, a device for short-distance transport of heavy objects using a monorail in coal mines is used. It is mounted on a monorail track 14 and includes a drive assembly. The drive assembly comprises a device housing 1, a drive gear set, a driven gear set, a ring drive chain 10, and a hoist 9. The device housing 1 has a U-shaped cross-section, primarily providing support for the various components of the device. The drive gear set includes a drive gear 3 and a driving gear 4, both rotatably mounted to the inner side of the device housing 1 via a drive shaft 2. The two ends of the drive shaft 2 are rotatably mounted to the inner sides of two vertical sidewalls of the device housing 1 via support bearings. The drive gear 3 and the driving gear 4 are coaxially fixed to the drive shaft 2 via keys and rotate synchronously. The driven gear set comprises two sets, respectively located on the left and right sides of the drive shaft 2, symmetrically arranged with the vertical plane containing the central axis of the drive shaft 2 as the plane of symmetry, and at the same horizontal height; each driven gear set includes two symmetrically arranged driven gear disks, which are rotatably mounted on the inner surfaces of the two vertical side walls of the device housing 1; each driven gear disk includes a sleeve shaft 5, a driven gear 6, and a drive pulley 7, wherein the driven gear 6 and the drive pulley 7 are coaxially fixed to the sleeve shaft 5 by a key, or the... The driven gear 6, drive pulley 7, and sleeve shaft 5 are integrally welded, with one end of the sleeve shaft 5 open. Correspondingly, two fixed shafts 11 are fixedly installed on the inner surfaces of the two vertical sidewalls of the device housing 1, perpendicular to them and extending inward. The sleeve shaft 5 is coaxially mounted to the corresponding fixed shaft 11 via bearings. The drive pulley 7 is located on the side of the driven gear 6 away from the device housing 1. Both driven gears 6 on one side mesh with the drive gear 4, and the drive gear 3 meshes with the ring drive zipper 10. The bottom plate of the device housing 1 has a long, narrow slot 12 that extends through its thickness, located directly below the drive gear 3. The central axis of the slot 12 in the length direction coincides with the longitudinal center plane of the drive gear 3, and its width is slightly greater than the thickness of the drive gear 3. The ring drive zipper 10 passes through the slot 12 and extends downward. A downwardly extending hanging connecting piece 8 is welded and fixed at the center of the bottom surface of the bottom plate of the device housing 1. The hanging connecting piece 8 is provided with a hanging hole. The hoisting hoist 9 is hung on the hanging hole of the hanging connecting piece 8. A 1-3T hand chain hoist can be used to lift heavy objects.

[0025] In a further optimized technical solution, a compression spring 13 is installed between the inner end of the fixed shaft 11 and the inner end of the inner cavity of the sleeve shaft 5, which is used to press the drive pulley 7 onto the monorail track 14.

[0026] In use, the entire device is installed from one end of the monorail 14 onto the monorail 14. The monorail 14 has an I-shaped cross-section, with the drive shaft 2 located below the bottom surface of the monorail 14. The drive pulley 7 in the driven gear set is slidably installed onto the I-shaped groove of the monorail 14. The two drive pulleys 7 in the same set are located on both sides of the monorail 14, so that the entire device is clamped and hung on the monorail 14. At the same time, the compression spring 13 between the fixed shaft 11 and the sleeve shaft 5 is used to keep the drive pulley 7 pressed against the monorail 14 to prevent the drive pulley 7 from detaching. The heavy object to be moved is then hoisted by hoist 9 and suspended off the ground. Then, the staff manually pulls the ring drive chain 10 to drive the drive gear 3 to rotate. Since it is fixed coaxially with the drive gear 4, the drive gear 4 rotates synchronously, which in turn drives the two sets of driven gears 6 to rotate through meshing. Since the driven gear 6 is fixed coaxially with the drive pulley 7, the drive pulley 7 rotates synchronously while the driven gear 6 rotates, so that it can move on the monorail track 14, thereby moving the heavy object for short-distance transportation.

[0027] Furthermore, a non-slip and wear-resistant wheel sleeve is fixedly installed on the outer circumferential side of the drive pulley 7 to increase friction with the monorail track 14, thereby better realizing travel and transportation.

[0028] Example 2,

[0029] A device for short-distance transport of heavy objects using a monorail in coal mines includes a drive assembly. Its overall structural features are similar to the technical solution described in Embodiment 1 above. The difference lies in that: one end of the drive shaft 2 in the drive gear assembly extends outward through the vertical side wall of the device housing 1; the drive gear 3 is coaxially fixed to the outer end of the extended drive shaft 2 by a key; and the ring drive zipper 10 engages with the drive gear 3 on the outside of the device housing 1. Simultaneously, a protective cover is bolted to the outer wall of the device housing 1, covering the outside of the drive gear 3. The bottom plate of the device housing 1 does not have a long, narrow slot 12.

[0030] Example 3,

[0031] A device for short-distance transport of heavy objects using a monorail in coal mines includes a drive assembly. Its overall structural features are the same as those described in Embodiment 1 above, except that it also includes a handheld drive device. The handheld drive device includes a handheld bracket, a drive motor, a control switch, and a safety braking structure. The drive motor is fixedly mounted on the handheld bracket, and a drive sprocket is coaxially fixedly mounted on its output end. The drive sprocket can engage with a ring drive zipper 10. The control switch is located on the handle of the handheld bracket and is connected to the drive motor via a circuit to control the start and stop of the drive motor and its rotation direction. The safety braking structure, also located on the handle of the handheld bracket, includes a handbrake structure, mainly used for braking the drive sprocket.

[0032] Using the devices described in the above embodiments, the existing monorail track 14 can be fully utilized to transport heavy objects at locations where the monorail locomotive is obstructed but there is a monorail track 14, thus filling the gap in monorail locomotive transportation and representing a completely new approach.

[0033] Of course, the above description is not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention. Furthermore, descriptions of well-known structures and technologies have been omitted in the above description to avoid unnecessarily obscuring the concept of the present invention.
