[0018] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed description of the self-propelled coal mine transport vehicle of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] This embodiment discloses a self-propelled walking transport vehicle for coal mines. Traditional coal mine transport vehicles rely on complex drive mechanisms and track systems, which are not only costly and prone to failure, but also have outdated loading and unloading methods, resulting in safety hazards and stability issues. Referring to... Figure 1-9 It mainly includes multiple transport vehicle groups 1, which are detachably connected to each other. A propulsion mechanism 4 is rotatably connected to one side of each transport vehicle group 1. A track 3 is laid along the extension direction of the transport line to support and guide the movement of the multiple transport vehicle groups 1. A consignment mechanism is detachably connected to the top of the transport vehicle groups 1.

[0021] A propulsion mechanism 4 is rotatably connected to one side of a transport vehicle group 11, enabling autonomous movement of the transport vehicle group 1 on the track 3 without relying on an external power source or complex drive mechanism. The track 3 is laid along the extension direction of the transport line, providing stable support and guidance for the transport vehicle group 1, ensuring the continuity and reliability of transportation. In addition, a detachable consignment mechanism, which can be easily installed and removed from the top of the transport vehicle group 1, is used to carry and transport minerals, improving the flexibility and efficiency of loading and unloading.

[0022] Reference Figure 1-5 The transport vehicle assembly 1 includes: a transport frame 101, with several rollers 102 symmetrically rotatably connected to its bottom. The rollers 102 are adapted to the top of the track 3. An electric telescopic rod 103 is symmetrically fixed to both sides of the transport frame 101. A support frame 104 is bolted to both sides of the top of the transport frame 101, and a bearing is fixed to the top of the support frame 104. Each pair of transport frames 101 has a connecting rod 2 on its corresponding side wall, and the two ends of the connecting rod 2 are hinged to the side wall of the transport frame 101 by pins.

[0023] Support frames 104 are bolted to both sides of the top of the transport frame 101. Bearings are fixed to the top of the support frames 104 for supporting and connecting other components. To enable flexible connection of multiple transport units, connecting rods 2 are provided on the corresponding side walls of every two transport frames 101. The two ends of the connecting rods 2 are hinged to the side walls of the transport frame 101 by pins. This design allows the connecting rods 2 to rotate within a certain range, thus allowing for flexibility in connecting the transport units and adapting to tracks with different angles and curvatures.

[0024] Example 1: Refer to Figure 1-5 The transport mechanism includes: a first transport plate 5, on both sides of which are provided with grooves for the rotation of a rotating shaft 501, the rotating shaft 501 passing through a bearing fixed to the top of the support frame 104 and extending into the grooves; and a fixing rod 502, which is slidably connected to both sides of the top of the support frame 104, and the first transport plate 5 has insertion holes on both sides for the fixing rod 502 to slide into.

[0025] The rotating shaft 501 passes through the bearing fixed at the top of the support frame 104 and extends into the interior of the groove, thereby realizing the rotatable connection between the first transport plate 5 and the support frame 104. This design allows the first transport plate 5 to rotate relative to the support frame 104 within a certain range.

[0026] To further enhance the stability and reliability of the transport mechanism, Embodiment 1 also includes a fixing rod 502. The fixing rod 502 is slidably connected to both sides of the top of the support frame 104, while the first transport plate 5 has insertion holes on both sides that match the fixing rod 502. Once the first transport plate 5 is adjusted to the appropriate position, the fixed rod 502 can be slid and inserted into the insertion holes to achieve a stable installation of the transport plate. This design not only simplifies the installation process but also improves the stability and safety of the transport mechanism during transportation. Example 2: Refer to Figure 1 , Figure 6 and Figure 7 The second transport plate 6 is inserted into the top of the transport frame 101.

[0027] The second transport plate 6 adopts a plug-in design, which can be directly plugged into the top of the transport frame 101 without the need for additional connectors or bolts. This design not only simplifies the installation and disassembly process, but also improves the flexibility and adaptability of the transport mechanism.

[0028] Specifically, the bottom of the second pallet 6 is designed with a matching insertion slot or flange that mates with the top of the transport frame 101, allowing the pallet to fit snugly against the top of the transport frame. To install the pallet, simply align it with the insertion point on the transport frame and gently push it in. Similarly, to remove the pallet, simply pull it gently out of the insertion point on the transport frame.

[0029] Reference Figure 1 and Figure 8 , 9 The propulsion mechanism 4 includes: a movable frame 401, which slides against the outer surface of the track 3; a hydraulic telescopic rod 402, one end of which is hinged to one side of the movable frame 401 via a pin; a first hydraulic telescopic cylinder 403, one end of which is hinged to a connecting block 404 via a pin, and the other end of which is telescopically connected to the hydraulic telescopic rod 402; the connecting block 404 is fixed to both sides of one of the transport frames 101; a second hydraulic telescopic cylinder 405, the output end of which is connected to a connecting channel 407, the connecting channel 407 being fixed to both sides of the movable frame 401, and the connecting channel 407 being connected to a pushing block 408, which extends into the interior of the movable frame 401; and several rollers 406 rotatably connected to the inner top wall of the movable frame 401.

[0030] The movable frame 401, serving as the basic structure of the propulsion mechanism, slides against the outer surface of the track 3, ensuring smooth movement of the propulsion mechanism on the track. The hydraulic telescopic rod 402 is hinged to one side of the movable frame 401 via a pin, enabling adjustment of its angle and length according to the extension and retraction of the hydraulic telescopic cylinder 403, thereby propelling the transport vehicle forward.

[0031] One end of the first hydraulic telescopic cylinder 403 is hinged to the connecting block 404 via a pin, and the other end is telescopically connected to a hydraulic telescopic rod 402. The connecting block 404 is fixed to both sides of one of the transport vehicle frames 101, so that the telescopic action of the hydraulic telescopic cylinder 403 can be converted into the moving power of the transport vehicle group.

[0032] In addition, the propulsion mechanism 4 is equipped with a second hydraulic telescopic cylinder 405, the output end of which is connected to a connecting channel 407, which is fixed to both sides of the moving frame 401. A push block 408 is provided inside the connecting channel 407, which extends into the interior of the moving frame 401 to provide additional thrust to fix the position of the moving frame when needed.

[0033] To reduce frictional resistance during movement, several rollers 406 are rotatably connected to the inner top wall of the moving frame 401. These rollers can roll as the moving frame moves, effectively reducing friction with the track and improving the moving efficiency and stability of the propulsion mechanism.

[0034] The working principle of the self-propelled coal mine transport vehicle of this utility model is as follows: When using this device, first place the track 3 in the reserved position outside, then place multiple transport vehicle groups 1 on the track 3, and connect the hydraulic telescopic cylinder and the external centrifugal pump through pipelines.

[0035] When moving the transport vehicle 1, firstly, the second hydraulic telescopic cylinder 405 is activated. The second hydraulic telescopic cylinder 405 pushes the push block 408 to move through the connecting channel 407. The push block 408 fits and clamps against the track 3, thereby fixing the moving frame 401 to the track 3. Then, the first hydraulic telescopic cylinder 403 is activated. The first hydraulic telescopic cylinder 403 pushes the hydraulic telescopic rod 402, thereby pushing the transport frame 101 to move on the track 3. Then, the second hydraulic telescopic cylinder 405 is activated again, causing the push block 408 to retract and no longer fit and clamp against the track 3. Then, the first hydraulic telescopic cylinder 403 is activated to retract the hydraulic telescopic rod 402, thereby driving the moving frame 401 to move on the track 3, reducing the distance between the moving frame 401 and the transport frame 101. Then, the above steps are repeated to move the transport frame 101 on the track 3.

[0036] When the track 3 is being laid, the electric telescopic rod 103 is activated, which lifts the transport frame 101, causing the rollers 102 to disengage from the track 3. Then, the second hydraulic telescopic cylinder 405 is activated, which pushes the push block 408 through the connecting channel 407, causing the push block 408 to clamp against the track 3. Next, the first hydraulic telescopic cylinder 403 is activated to retract the hydraulic telescopic rod 402, which pulls the moving frame 401 and the track 3, allowing the track 3 to be laid forward. Then, the second hydraulic telescopic cylinder 405 is activated again, causing the push block 408 to retract and no longer clamp against the track 3. Then, the first hydraulic telescopic cylinder 403 is activated to push the hydraulic telescopic rod 402, thereby moving the moving frame 401 on the track 3, increasing the distance between the moving frame 401 and the transport frame 101. The above steps are then repeated to continue laying the track 3.

[0037] After the moving track 3 is completed, the electric telescopic rod 103 is activated to lower the transport vehicle frame 101, so that the rollers 102 at the bottom of the transport vehicle frame 101 fall onto the track 3 to continue moving the transport vehicle frame 101.

[0038] When using the consignment mechanism: First embodiment: When using the first consignment plate 5, the material is placed on the top of the first consignment plate 5. When it is necessary to remove the material, the fixing rod 502 is pulled out from the first consignment plate 5, so that the first consignment plate 5 can rotate, making it easier to remove the material.

[0039] Second embodiment: When using the second transport plate 6, the rotating shaft 501 is pulled out of the bearing, the first transport plate 5 is taken out, and then the support frame 104 is moved up and down on the transport frame 101 so that the second transport plate 6 is snapped onto the top of the transport frame 101.

Furthermore, the accompanying drawings and abstract drawings are merely illustrative and do not represent the specific structure or actual quantity in a concrete implementation.
