Description

Technical Field

[0001] This utility model belongs to the field of vehicle manufacturing equipment technology, and specifically relates to a braking device for rail transport vehicles. Background Technology

[0002] Braking, also known as braking, refers to the action of stopping or reducing the speed of locomotives, vehicles, and other transportation vehicles or machinery in operation. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, and install appropriate brake shoes, belts, or discs on the machine base. Under the action of external force, a braking torque is generated. The braking device is a mechanical braking device that can slow down rail transport vehicles, also known as a speed reducer.

[0003] Traditional rail transport vehicles typically brake using a hydraulic braking mechanism when they reach the required position. However, this hydraulic braking mechanism requires a separate hydraulic station to operate, which occupies installation space on the rail transport vehicle. Furthermore, the hydraulic braking mechanism has a complex structure and high cost, thus increasing the manufacturing cost of the rail transport vehicle. Utility Model Content

[0032] Example 1.

[0033] like Figure 1-10 As shown, the present invention provides a braking device for a rail transport vehicle, comprising a first drive shaft 1 rotatably mounted on the frame of the transport vehicle, a pair of brake mounting seats 2 fixedly mounted on the frame of the transport vehicle, a braking mechanism slidably mounted within the brake mounting seats 2, a second drive shaft 3 rotatably mounted on the two brake mounting seats 2, two sets of transmission mechanisms located between the first drive shaft 1 and the second drive shaft 3, and a drive mechanism mounted on the frame of the transport vehicle and connected to one of the sets of transmission mechanisms; a reset mechanism is provided between the brake mounting seats 2 and the braking mechanism, and the driven wheel of the transport vehicle is rotatably mounted on the brake mounting seats 2 and located directly below the braking mechanism.

[0034] This utility model has a simple structure, a scientific and reasonable design, and is easy to use. It consists of a first transmission shaft 1, a brake mounting base 2, a brake mechanism, a second transmission shaft 3, a transmission mechanism, and a drive mechanism. Its structure is simple and its manufacturing cost is low.

[0035] This utility model uses two sets of transmission mechanisms to facilitate the synchronous rotation of the second transmission shaft 3. At the same time, the second transmission shaft 3 can drive the two sets of connecting lugs 15 to rotate simultaneously, thereby enabling the connecting lugs 15 to drive the two braking mechanisms to operate, which facilitates the braking of the rail transport vehicle.

[0036] In use, the electric push rod 17 drives the perforated connecting plate 12 to rotate, which in turn drives the first transmission shaft 1 to rotate. During rotation, the first transmission shaft 1 drives another set of transmission mechanisms to rotate synchronously. Simultaneously, the perforated connecting plate 12 drives the transmission ear plate 13 to rotate via two pull rods 14. The transmission ear plate 13 drives the second transmission shaft 3 to rotate, which in turn drives the two connecting ear plates 15 to rotate. During rotation, the connecting ear plates 15 push the arc-shaped mounting plate 6 downward and stretch the return spring 11. The arc-shaped mounting plate 6 drives the arc-shaped brake pad 7 downward, so that the arc-shaped brake pad 7 contacts the driven wheel of the transport vehicle, thereby braking the driven wheel of the transport vehicle. This facilitates braking the driven wheel of the transport vehicle, and its structure is relatively simple, which can reduce the manufacturing cost of the transport vehicle. When the transport vehicle is moving, the electric push rod 17 causes the connecting ear plate 15 to separate from the arc-shaped mounting plate 6. At the same time, the arc-shaped mounting plate 6 moves upward under the action of the return spring 11. The arc-shaped mounting plate 6 drives the arc-shaped brake pad 7 to move upward and separate from the driven wheel of the transport vehicle, thereby reducing the resistance of the transport vehicle when it is moving.

[0037] Example 2.

[0038] like Figure 1-10 As shown, the present invention provides a braking device for a rail transport vehicle, comprising a first drive shaft 1 rotatably mounted on the frame of the transport vehicle, a pair of brake mounting seats 2 fixedly mounted on the frame of the transport vehicle, a braking mechanism slidably mounted within the brake mounting seats 2, a second drive shaft 3 rotatably mounted on the two brake mounting seats 2, two sets of transmission mechanisms located between the first drive shaft 1 and the second drive shaft 3, and a drive mechanism mounted on the frame of the transport vehicle and connected to one of the sets of transmission mechanisms; a reset mechanism is provided between the brake mounting seats 2 and the braking mechanism, and the driven wheel of the transport vehicle is rotatably mounted on the brake mounting seats 2 and located directly below the braking mechanism.

[0039] The braking mechanism includes a guide sleeve 4 disposed in the brake mounting seat 2, a brake rod 5 slidably disposed in the guide sleeve 4, an arc-shaped mounting plate 6 disposed on the brake rod 5 and connected to the reset mechanism, and an arc-shaped brake pad 7 disposed on the arc-shaped mounting plate 6.

[0040] In this embodiment 2, both the guide sleeve 4 and the brake rod 5 are hollow rectangular structures, and the brake rod 5 is slidably disposed inside the guide sleeve 4. The guide sleeve 4 can guide the movement direction of the brake rod 5, thereby facilitating the braking of the rail transport vehicle.

[0041] In this embodiment 2, during use, the connecting ear plate 15 pushes the arc-shaped mounting plate 6 downward during rotation, and the arc-shaped mounting plate 6 drives the arc-shaped brake pad 7 to move synchronously, so that the arc-shaped brake pad 7 contacts the driven wheel of the transport vehicle, thereby realizing the braking of the rail transport vehicle.

[0042] Example 3.

[0043] like Figure 1-10 As shown, the present invention provides a braking device for a rail transport vehicle, comprising a first drive shaft 1 rotatably mounted on the frame of the transport vehicle, a pair of brake mounting seats 2 fixedly mounted on the frame of the transport vehicle, a braking mechanism slidably mounted within the brake mounting seats 2, a second drive shaft 3 rotatably mounted on the two brake mounting seats 2, two sets of transmission mechanisms located between the first drive shaft 1 and the second drive shaft 3, and a drive mechanism mounted on the frame of the transport vehicle and connected to one of the sets of transmission mechanisms; a reset mechanism is provided between the brake mounting seats 2 and the braking mechanism, and the driven wheel of the transport vehicle is rotatably mounted on the brake mounting seats 2 and located directly below the braking mechanism.

[0044] The braking mechanism includes a guide sleeve 4 disposed in the brake mounting seat 2, a brake rod 5 slidably disposed in the guide sleeve 4 and connected to the reset mechanism, an arc-shaped mounting plate 6 disposed on the brake rod 5, and an arc-shaped brake pad 7 disposed on the arc-shaped mounting plate 6.

[0045] The brake mounting base 2 is provided with a clearance groove 8 that communicates with the guide sleeve 4. The reset mechanism includes a connecting seat A9 on the brake mounting base 2, a connecting seat B10 on the arc-shaped mounting plate 6 and located inside the brake rod 5, and a reset spring 11 with one end connected to the connecting seat A9 and the other end connected to the connecting seat B10.

[0046] In this embodiment 3, the guide sleeve 4 is welded into the relief groove 8, the connecting seat A9 is set on the brake rod 5, and the connecting end of the connecting seat A9 is located in the relief groove 8. At the same time, the connecting seat B10 is set on the arc-shaped mounting plate 6, and the connecting seat B10 is located in the middle of the brake rod 5. In use, when the connecting ear plate 15 pushes the arc-shaped mounting plate 6 downward during rotation, the arc-shaped mounting plate 6 stretches the return spring 11, so that the arc-shaped brake pad 7 contacts the driven wheel of the transport vehicle, thereby braking the rail transport vehicle. When the connecting ear plate 15 separates from the arc-shaped mounting plate 6, the return spring 11 drives the arc-shaped mounting plate 6 upward, so that the arc-shaped brake pad 7 separates from the driven wheel of the transport vehicle, thereby facilitating the movement of the transport vehicle.

[0047] Example 4.

[0048] like Figure 1-10As shown, the present invention provides a braking device for a rail transport vehicle, comprising a first drive shaft 1 rotatably mounted on the frame of the transport vehicle, a pair of brake mounting seats 2 fixedly mounted on the frame of the transport vehicle, a braking mechanism slidably mounted within the brake mounting seats 2, a second drive shaft 3 rotatably mounted on the two brake mounting seats 2, two sets of transmission mechanisms located between the first drive shaft 1 and the second drive shaft 3, and a drive mechanism mounted on the frame of the transport vehicle and connected to one of the sets of transmission mechanisms; a reset mechanism is provided between the brake mounting seats 2 and the braking mechanism, and the driven wheel of the transport vehicle is rotatably mounted on the brake mounting seats 2 and located directly below the braking mechanism.

[0049] The transmission mechanism includes two perforated connecting plates 12 mounted on the first transmission shaft 1 and connected to the drive mechanism, two transmission lugs 13 mounted on the second transmission shaft 3, a connecting post 25 between the two transmission lugs 13, a pull rod 14 with one end connected to one of the perforated connecting plates 12 and the other end connected to the connecting post 25, and two connecting lugs 15 mounted on the second transmission shaft 3 and in contact with the braking mechanism.

[0050] In this embodiment 4, a hinge shaft is provided between the two perforated connecting plates 12, and a hinge hole adapted to the hinge shaft is provided on the output end of the electric push rod 17. The hinge shaft is rotatably mounted on the hinge shaft.

[0052] In this embodiment 4, the perforated connecting plate 12 and the connecting post 25 are respectively provided with connecting holes 26 that are adapted to the pull rod 14. One end of the pull rod 14 is connected to the connecting hole 26 on the perforated connecting plate 12, and the other end is connected to the connecting hole 26 on the transmission ear plate 13.

[0053] In this embodiment 4, the two connecting lugs 15 are located on both sides of the brake lever 5, and the two connecting lugs 15 can facilitate the movement of the arc-shaped mounting plate 6.

[0054] In this embodiment 4, during use, since the perforated connecting plate 12 is mounted on the first drive shaft 1, when the electric push rod 17 moves the perforated connecting plate 12, another set of transmission mechanisms will rotate synchronously with the first drive shaft 1. At the same time, during the rotation of the perforated connecting plate 12, it pushes the pull rod 14 to move. Under the action of the linkage principle, the pull rod 14 will push the transmission ear plate 13 to rotate when it moves. The transmission ear plate 13 drives the second drive shaft 3 to rotate, and the second drive shaft 3 drives the connecting ear plate 15 to rotate, so that the connecting ear plate 15 contacts or separates from the arc-shaped mounting plate 6, thereby facilitating the braking of the rail transport vehicle.
