[0031] Example 1.

[0032] like Figure 1-9 As shown, the present invention provides a rail transport vehicle, comprising a frame 1, two drive wheels 2 rotatably mounted at the bottom of the frame 1, two brake mounting seats 4 fixedly mounted at the bottom of the frame 1, driven wheels 3 rotatably mounted on the brake mounting seats 4, a brake mechanism slidably mounted in the brake mounting seats 4 and located directly above the driven wheels 3, and a brake drive mechanism rotatably mounted on the frame 1 at one end and on the brake mounting seats 4 at the other end and in contact with the brake mechanism; the frame 1 is provided with a moving drive mechanism connected to the two drive wheels 2, and the frame 1 is provided with a control mechanism connected to the moving drive mechanism and the brake drive mechanism.

[0033] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It consists of a frame 1, a control mechanism, a moving drive mechanism, a braking drive mechanism, two brake mounting seats 4, two driving wheels 2, two driven wheels 3, and two braking mechanisms. Its structure is relatively simple and can effectively reduce the manufacturing cost of the transport vehicle.

[0034] The active wheel 2 and driven wheel 3 of this utility model provide overall support for the trolley. The active wheel 2 and driven wheel 3 are distributed at the bottom of the frame 1, thereby reducing the resistance of the frame 1 when moving. In use, the moving drive mechanism drives the two active wheels 2 to rotate. The active wheels 2 drive the two driven wheels 3 to rotate on the track through the frame 1, thereby enabling the transport vehicle to move on the track and transport goods. When the transport vehicle transports the goods to the required position, the braking drive mechanism drives the braking mechanism to brake the driven wheels 3, so that the transport vehicle can stop on the track, which facilitates the loading and unloading of materials on the transport vehicle.

[0035] The braking mechanism of this utility model consists of a brake lever 5, an arc-shaped mounting plate 6, an arc-shaped brake pad 7, and a reset mechanism, which makes the braking mechanism simple in structure, while also achieving a good braking effect and reducing the manufacturing cost of the transport vehicle.

[0036] Example 2.

[0037] like Figure 1-9As shown, the present invention provides a rail transport vehicle, comprising a frame 1, two drive wheels 2 rotatably mounted at the bottom of the frame 1, two brake mounting seats 4 fixedly mounted at the bottom of the frame 1, driven wheels 3 rotatably mounted on the brake mounting seats 4, a brake mechanism slidably mounted in the brake mounting seats 4 and located directly above the driven wheels 3, and a brake drive mechanism rotatably mounted on the frame 1 at one end and on the brake mounting seats 4 at the other end and in contact with the brake mechanism; the frame 1 is provided with a moving drive mechanism connected to the two drive wheels 2, and the frame 1 is provided with a control mechanism connected to the moving drive mechanism and the brake drive mechanism.

[0038] The braking mechanism includes a brake rod 5 slidably disposed within the brake mounting seat 4, an arc-shaped mounting plate 6 disposed on the brake rod 5 and in contact with the brake drive mechanism, and an arc-shaped brake pad 7 disposed on the arc-shaped mounting plate 6; a reset mechanism is provided between the brake mounting seat 4 and the brake rod 5.

[0039] In this embodiment 2, one end of the reset mechanism is connected to the brake mounting base 4 and the other end is connected to the brake lever 5. The reset mechanism can separate the arc-shaped brake pad 7 from the driven wheel 3, preventing the driven wheel 3 from contacting the arc-shaped brake pad 7 during rotation. In use, the brake drive mechanism drives the arc-shaped mounting plate 6 to move downward and stretches the reset mechanism. The arc-shaped mounting plate 6 drives the brake lever 5 and the arc-shaped brake pad 7 to move synchronously, thereby making the driven wheel 3 contact the arc-shaped brake pad 7, thus achieving braking of the driven wheel 3. When the transport vehicle is moving, the brake drive mechanism separates from the arc-shaped brake pad 7, and the brake lever 5 moves upward under the drive of the reset mechanism. The brake lever 5 drives the arc-shaped mounting plate 6 and the arc-shaped brake pad 7 to move synchronously, thereby making the arc-shaped brake pad 7 separate from the driven wheel 3, which facilitates the movement of the transport vehicle.

[0040] In this embodiment 2, the brake mounting base 4 is provided with a brake clearance groove, and the brake rod 5 is slidably disposed in the brake clearance groove. The brake clearance groove can guide the movement direction of the brake rod 5.

[0042] like Figure 1-9 As shown, the present invention provides a rail transport vehicle, comprising a frame 1, two drive wheels 2 rotatably mounted at the bottom of the frame 1, two brake mounting seats 4 fixedly mounted at the bottom of the frame 1, driven wheels 3 rotatably mounted on the brake mounting seats 4, a brake mechanism slidably mounted in the brake mounting seats 4 and located directly above the driven wheels 3, and a brake drive mechanism rotatably mounted on the frame 1 at one end and on the brake mounting seats 4 at the other end and in contact with the brake mechanism; the frame 1 is provided with a moving drive mechanism connected to the two drive wheels 2, and the frame 1 is provided with a control mechanism connected to the moving drive mechanism and the brake drive mechanism.

[0043] The braking mechanism includes a brake rod 5 slidably disposed within the brake mounting seat 4, an arc-shaped mounting plate 6 disposed on the brake rod 5 and in contact with the brake drive mechanism, and an arc-shaped brake pad 7 disposed on the arc-shaped mounting plate 6; a reset mechanism is provided between the brake mounting seat 4 and the brake rod 5.

[0044] The braking drive mechanism includes a first rotating rod 9 rotatably mounted on the frame 1, a second rotating rod 12 rotatably mounted between two brake mounting seats 4, a connecting ear plate 15 mounted on the second rotating rod 12 and in contact with the top of both sides of the arc-shaped mounting plate 6, two sets of transmission mechanisms connected between the first rotating rod 9 and the second rotating rod 12, and an electric push rod 8 mounted on the frame 1 and connected to one of the transmission mechanisms; the electric push rod 8 is connected to the control mechanism.

[0045] In this embodiment 3, the transmission principle of the transmission mechanism is as follows: when the transport vehicle needs to stop, the electric push rod 8 operates. The electric push rod 8 drives the first rotating rod 9 and the second rotating rod 12 to rotate synchronously through the transmission mechanism. The second rotating rod 12 drives the connecting ear plate 15 to rotate synchronously. During the rotation, the connecting ear plate 15 pushes the arc-shaped mounting plate 6 to move downward and stretches the return spring 18, so that the arc-shaped brake pad 7 contacts the driven wheel 3, thereby braking the transport vehicle.

[0046] When the transport vehicle needs to move, the electric push rod 8 drives the first rotating rod 9 and the second rotating rod 12 to rotate synchronously through the transmission mechanism. The second rotating rod 12 drives the connecting ear plate 15 to rotate synchronously, so that the connecting ear plate 15 separates from the arc-shaped mounting plate 6. The arc-shaped brake pad 7 separates from the driven wheel 3 under the drive of the return spring 18, thereby facilitating the movement of the transport vehicle.

[0047] Example 4.

[0048] like Figure 1-9 As shown, the present invention provides a rail transport vehicle, comprising a frame 1, two drive wheels 2 rotatably mounted at the bottom of the frame 1, two brake mounting seats 4 fixedly mounted at the bottom of the frame 1, driven wheels 3 rotatably mounted on the brake mounting seats 4, a brake mechanism slidably mounted in the brake mounting seats 4 and located directly above the driven wheels 3, and a brake drive mechanism rotatably mounted on the frame 1 at one end and on the brake mounting seats 4 at the other end and in contact with the brake mechanism; the frame 1 is provided with a moving drive mechanism connected to the two drive wheels 2, and the frame 1 is provided with a control mechanism connected to the moving drive mechanism and the brake drive mechanism.

[0049] The braking mechanism includes a brake rod 5 slidably disposed within the brake mounting seat 4, an arc-shaped mounting plate 6 disposed on the brake rod 5 and in contact with the brake drive mechanism, and an arc-shaped brake pad 7 disposed on the arc-shaped mounting plate 6; a reset mechanism is provided between the brake mounting seat 4 and the brake rod 5.

[0050] The braking drive mechanism includes a first rotating rod 9 rotatably mounted on the frame 1, a second rotating rod 12 rotatably mounted between two brake mounting seats 4, a connecting ear plate 15 mounted on the second rotating rod 12 and in contact with the top of both sides of the arc-shaped mounting plate 6, two sets of transmission mechanisms connected between the first rotating rod 9 and the second rotating rod 12, and an electric push rod 8 mounted on the frame 1 and connected to one of the transmission mechanisms; the electric push rod 8 is connected to the control mechanism.

[0051] The transmission mechanism includes two perforated connecting plates 10 disposed on the first rotating rod 9 and connected to the output end of the electric push rod 8, a transmission ear plate 13 disposed on the second rotating rod 12 and connected to one of the perforated connecting plates 10, and a pull rod 14 connected at one end to the perforated connecting plate 10 and at the other end to the transmission ear plate 13.

[0052] In this embodiment 4, a connecting shaft is provided between the two perforated connecting plates 10, and a connecting hole is provided on the output end of the electric push rod 8. The connecting shaft is rotatably located in the connecting hole. In use, the electric push rod 8 pushes the two perforated connecting plates 10 to rotate, and the two perforated connecting plates 10 drive the first rotating rod 9 to rotate. The perforated connecting plates 10 drive the transmission ear plate 13 to rotate through the pull rod 14. The transmission ear plate 13 drives the second rotating rod 12 to move synchronously, so that the second rotating rod 12 moves synchronously with the first rotating rod 9. The second rotating rod 12 drives the connecting ear plate 15 to rotate, thereby driving the arc-shaped brake pad 7 to contact the driven wheel 3, which facilitates braking of the transport vehicle.

[0053] Example 5.

[0054] like Figure 1-9 As shown, the present invention provides a rail transport vehicle, comprising a frame 1, two drive wheels 2 rotatably mounted at the bottom of the frame 1, two brake mounting seats 4 fixedly mounted at the bottom of the frame 1, driven wheels 3 rotatably mounted on the brake mounting seats 4, a brake mechanism slidably mounted in the brake mounting seats 4 and located directly above the driven wheels 3, and a brake drive mechanism rotatably mounted on the frame 1 at one end and on the brake mounting seats 4 at the other end and in contact with the brake mechanism; the frame 1 is provided with a moving drive mechanism connected to the two drive wheels 2, and the frame 1 is provided with a control mechanism connected to the moving drive mechanism and the brake drive mechanism.

[0055] The braking mechanism includes a brake rod 5 slidably disposed within the brake mounting seat 4, an arc-shaped mounting plate 6 disposed on the brake rod 5 and in contact with the brake drive mechanism, and an arc-shaped brake pad 7 disposed on the arc-shaped mounting plate 6; a reset mechanism is provided between the brake mounting seat 4 and the brake rod 5.

[0056] The reset mechanism includes a connecting seat A16 located in the brake mounting seat 4, a connecting seat B17 located in the brake lever 5, and a reset spring 18 connected at one end to the connecting seat A16 and at the other end to the connecting seat B17.

[0057] In this embodiment 5, when the transport vehicle needs to stop, the connecting ear plate 15 pushes the arc-shaped mounting plate 6 downward, causing the brake lever 5 and the arc-shaped brake pad 7 to move synchronously with the arc-shaped mounting plate 6. At the same time, the brake lever 5 stretches the return spring 18 during movement, causing the arc-shaped brake pad 7 to contact the outer wall of the driven wheel 3, thereby achieving braking. When the transport vehicle moves, the connecting ear plate 15 separates from the arc-shaped mounting plate 6, and the return spring 18 drives the brake lever 5 to move upward. The brake lever 5 drives the arc-shaped mounting plate 6 and the arc-shaped brake pad 7 to move synchronously, thereby causing the arc-shaped brake pad 7 to separate from the outer wall of the driven wheel 3, thus facilitating the movement of the transport vehicle.

[0061] In this embodiment 6, the drive motor 19 is started, and the drive motor 19 drives the drive gear 20 to rotate. Since the driven gear 23 meshes with the drive gear 20, the driven gear 23 rotates synchronously with the drive gear 20. The driven gear 23 drives the drive shaft 22 to rotate, and the drive shaft 22 drives the drive wheel 2 to rotate, so that the drive wheel 2 moves on the track, thereby driving the transport vehicle to move on the track.

The two batteries 26 can effectively increase the driving range of the transport vehicle. When in use, the operator issues control commands to the microcontroller 25 through the control panel. The microcontroller 25 controls the electric push rod 8 or the drive motor 19 to run according to the control commands, thereby facilitating the movement or stopping of the transport vehicle.

[0076] Working principle

[0077] When the transport vehicle of this utility model is moving, the operator issues a movement command to the microcontroller 25 through the control panel.

[0078] When the transport vehicle needs to stop, the microcontroller 25 controls the electric push rod 8 to operate. The electric push rod 8 pushes the perforated connecting plate 10 to rotate.

When the transport vehicle is moving, the arc-shaped brake pad 7 separates from the driven wheel 3 under the action of the return spring 18, thus facilitating the movement of the transport vehicle.
