[0002] A monorail in a coal mine is an auxiliary transportation device that travels along a track on the top of a roadway. It uses a specially made I-beam suspended above the roadway as a track to connect various types of suspended vehicles into a trainset, which is then pulled along the track by a traction device.

[0003] Patent CN222433947U discloses a monorail auxiliary material transport device for underground coal mines. Multiple fastening mechanisms are installed between the first and second load-bearing plates to facilitate connection and disassembly. During assembly, the two load-bearing plates are connected by a first and second connecting rod. A first and second limiting block respectively limit one end of the connecting rod, and a first and second locking assembly respectively locks the other end of the connecting rod, completing the fixation. During disassembly, the locking assembly is released from the connecting rod, and the connecting rod can be pulled out by pulling the limiting block. However, in application, because the monorail is suspended from the top of the roadway, the two fastening mechanisms located above the track can obstruct the device's operation as it moves along the track, causing malfunctions due to obstruction from the track suspension connectors.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] like Figures 1-4As shown, this embodiment provides a monorail auxiliary material transport device for underground coal mines, including a traveling component and a connecting component. The traveling component includes a support frame 1 and traveling wheels 2 installed on the support frame 1. The traveling wheels 2 are located on the monorail beam and can slide along the monorail beam. The side wall of the support frame 1 is provided with a plurality of first through holes 11 to reduce its own weight. The traveling wheels 2 are rotatably connected to the side wall of the support frame 1.

[0035] The connecting components include a support frame 3 fixed to the bottom of the support frame 1 and a connecting structure detachably installed on the support frame 3. The connecting structure includes connecting ears 4 and lifting rings 5. The connecting ears 5 can be selectively connected to the support frame 3, thus allowing adjustment of the distance between the two pairs of connecting ears 4. This allows for adaptation to actual working conditions when connecting and hoisting objects. Multiple lifting rings 5 ​​are provided, enabling hoisting via chains.

[0036] In this embodiment, as Figures 3-6 As shown, the support frame 3 is a U-shaped frame with a second through hole 31 on its side wall to reduce its weight and facilitate the installation and removal of various connecting structures. Four mounting holes 32 are provided on the bottom surface of the support frame 3. Two mounting holes 32 form a group, meaning one group of mounting holes 32 is used to install a pair of connecting lugs 4. The two groups of mounting holes 32 are located on both sides of the lifting ring 5. That is, the lifting ring is installed in the center of the support frame 3, and a group of mounting holes 32 is provided on each side of the lifting ring, with a pair of connecting lugs 4 installed on each side.

[0037] Specifically, the mounting hole 32 is a strip-shaped hole, and the connecting ear 4 can slide within the mounting hole 32 and be installed in a preset position. The length of the mounting hole 32 is greater than the width of the connecting ear 4, and the width of the mounting hole 32 is greater than the thickness of the connecting ear 4, meaning that the connecting ear can be adjusted in position within the mounting hole in four directions: front, back, left, and right.

[0038] More specifically, one side of the mounting hole 32 is also provided with several first through holes 33 for fixing the connecting ear 4. The connecting ear 4 is an integral structure including a positioning plate 41 and a connecting plate 42. The positioning plate 41 is located above the bottom surface of the support frame 3 and can be selectively connected to the corresponding first through hole 33 through the positioning holes. The positioning plate 41 has several positioning holes 411. In this embodiment, the positioning plate 41 has six positioning holes 411, arranged in two rows of three. When installing the connecting ear 4, one row of positioning holes 411 is connected to three of the first through holes 33, and bolts are used for connection and fixation. Therefore, the distance between the two pairs of connecting ears 4 can be adjusted, and the distance between each connecting ear in each pair can also be fine-tuned, increasing the flexibility of the connecting ear installation. The connecting plate 42 passes through the mounting hole 32, and the lower end of the connecting plate 40 is provided with connecting holes 43 for connecting objects to be hoisted.

[0039] In this embodiment, the connecting component includes four lifting rings 5, each fixedly mounted on a hanging plate 6. The hanging plate 6 has four connecting holes 61.

The traveling wheels 2 are mounted on the side walls of the support frame 1, located on the monorail beam, and can slide along the monorail beam.

[0041] The support frame 3 is fixed to the bottom of the support frame 1. The second through hole 31 on its side wall is used to reduce its weight and facilitate the installation and removal of various connecting structures. The connecting lugs 4 are installed on the support frame 3 through strip-shaped mounting holes 32. They can slide along the mounting holes 32 and be installed in a preset position. Specifically, their positioning holes 411 can be selectively installed in the first through hole 33 on the side of the mounting hole 32. The spacing between the two pairs of connecting lugs 4 can be adjusted, allowing for selective installation of the connecting lugs 4 to accommodate objects of different sizes. The sliding and selective installation structure of the connecting lugs 4, along with the strip-shaped hole design of the mounting holes 32, allows the spacing between the connecting lugs 4 to be adjusted according to actual working conditions, thereby accommodating objects of different sizes and improving the versatility and flexibility of the device.

[0042] The hanging plate 6 is adapted to the second through hole 34 in the center of the support frame 3 through the connecting hole 61 on it, so as to achieve detachable installation. The lifting ring 5 can be connected to the chain to lift objects.

[0043] The monorail auxiliary material transport device for underground coal mines provided in this embodiment has a first through hole 11 and a second through hole 31 respectively arranged on the side walls of the support frame 1 and the support frame 3 to reduce its weight. The lightweight design not only reduces the energy consumption of the device, but also improves the operating efficiency and flexibility of the device.

[0044] The monorail auxiliary material transport device for underground coal mines provided in this embodiment features a detachable design for the lifting plate 6, allowing the lifting ring 5 to be installed or removed as needed, facilitating device maintenance and adjustment. Simultaneously, the design of the mounting hole 32 and the first through hole 33 also facilitates the installation and fixation of the connecting lug 4.

[0045] The coal mine underground monorail auxiliary material transport device provided in this embodiment solves the problem of obstruction by the rail suspension connector in the prior art by optimizing the design of the traveling and connecting components.
