Description

Technical Field

[0001] The utility model relates to the technical field of rail cranes, in particular to a braking device for a traveling mechanism of a rail crane at a container terminal. Background Art

[0002] The container terminal rail crane is a heavy mechanical equipment used for container loading and unloading operations at the port container terminal. It is usually composed of chassis, running mechanism, lifting mechanism and cab. Its main function is to unload containers from cargo ships at the dock, or transport containers from the yard to cargo ships for loading, or transport containers between container yards or between docks and yards. They travel along the preset tracks to move containers from one location to another, so as to organize and manage the goods in the yard more efficiently.

[0003] The current rail cranes usually use electromagnetic braking or brake air for braking. Due to the heavy weight of the crane, the electromagnetic braking system consumes electrical energy to activate the electromagnet to generate magnetic force during braking, resulting in high energy consumption. Electromagnetic braking relies solely on the clamping force of the electromagnetic caliper disc brake to achieve braking. After long-term use, the electromagnetic braking and the contact and friction between the electromagnet and the brake disc or brake drum will cause the brake components to wear, which will not only affect the braking effect, but also increase maintenance costs and downtime.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 As shown, a container terminal rail crane travel mechanism braking device includes a first outer cover 1, and also includes: a second outer cover 2 arranged on one side of the first outer cover 1, and the first outer cover 1 and the second outer cover 2 are detachably connected by screws, a positioning groove 3 is provided on one side of the inner cavity of the second outer cover 2, and a brake disc body 4 is provided in the inner cavity of the positioning groove 3; a support frame 5 is arranged on one side of the inner cavity of the first outer cover 1, and a braking mechanism 6 for braking is fixedly connected to one side of the inner cavity of the first outer cover 1, and the braking mechanism 6 includes a cylinder 69, and limiting holes 7 are provided on both sides of the inner cavity of the support frame 5, and a fixing plate 8 is welded to one side of the support frame 5.

[0021] refer to Figure 2 and Figure 4 As shown, the brake disc body 4 includes a circular ring 41 , a brake ring 42 is welded to one side of the circular ring 41 , and a heat dissipation hole 43 is opened on the surface of the brake ring 42 .

[0022] It should be noted that the circular ring 41 and the brake ring 42 facilitate braking of the traveling mechanism, and the heat dissipation holes 43 can assist in dissipating the heat generated by friction.

[0023] refer to Figure 3 and Figure 4As shown, one side of the cylinder 69 is fixedly connected to a positioning shell 61, and the inner cavity of the positioning shell 61 is movably connected to a guide wheel 62. Both sides of one side of the guide wheel 62 are movably in contact with a first inclined block 63, and the two first inclined blocks 63 are fixedly connected to a push rod 64 on the side away from the guide wheel 62. The side of the push rod 64 away from the first inclined block 63 passes through the outside of the support frame 5 and is fixedly connected to a mounting block 65. A brake pad 66 is installed on one side of the mounting block 65 through a hexagon socket screw, and a limiting strip 67 is welded to the top and bottom of the mounting block 65. The side of the limiting strip 67 close to the support frame 5 passes through the inner cavity of the support frame 5 and is welded to the first inclined block 63. A first spring 68 for auxiliary resetting is fixedly connected between the first inclined block 63 and the support frame 5, and the shape of the brake pad 66 is arc-shaped.

[0024] It should be noted that: the guide wheel 62 is driven to move by the extension and retraction of the cylinder 69. When the guide wheel 62 moves, it will press the first inclined block 63 to move. When the first inclined block 63 moves, it will drive the push rod 64 to move. When the push rod 64 moves, the mounting block 65 will drive the brake pad 66 to move, thereby applying braking friction to the ring 41. When the first inclined block 63 moves, it will drive the limit bar 67 to move, so that the mounting block 65 can move in a limited position, and at the same time, it will also compress the first spring 68. Then, when the brake is released, the first spring 68 will reset, which will cause the first inclined block 63 to move and reset the guide wheel 62.

[0025] refer to Figure 4 As shown, a connecting strip 9 is welded to one side of the limiting strip 67, a movable plate 10 is welded to one side of the connecting strip 9, one side of the movable plate 10 penetrates into the inner cavity of the limiting hole 7 and is fixedly connected to a second inclined block 11, one side of the second inclined block 11 is movably connected to a third inclined block 12, one side of the third inclined block 12 is fixedly connected to a positioning rod 13, one side of the positioning rod 13 is fixedly connected to a fixed block 14, one side of the fixed block 14 is provided with a friction ring 15 via a hexagon socket screw, a connecting plate 16 is fixedly connected to the surface of the positioning rod 13, and the side of the connecting plate 16 away from the positioning rod 13 penetrates to the outside of the fixed plate 8 and is fixedly connected to a limiting ring 17, and a second spring 18 for auxiliary reset is fixedly connected between the limiting ring 17 and the fixed plate 8.

[0026] It should be noted that: when the limit bar 67 moves, it will drive the movable plate 10 to move, and when the movable plate 10 moves, it will drive the second inclined block 11 to move. At this time, the second inclined block 11 contacts the inclined surface of the third inclined block 12, and then the third inclined block 12 will drive the positioning rod 13 to move the fixed block 14. When the fixed block 14 moves, the friction ring 15 will contact the circular ring 41 to assist in braking it. When the positioning rod 13 moves, it will drive the connecting plate 16 to make the limit ring 17 squeeze the second spring 18, and then when the brake is released, the friction ring 15 is reset by relying on the second spring 18.

[0027] Working principle: When the equipment is in use, it is electrically connected to the walking mechanism through the cylinder 69. When the user steps on the brake pedal, the cylinder 69 will extend and drive the guide wheel 62 to move. When the guide wheel 62 moves, it will press the first inclined block 63 to move. When the first inclined block 63 moves, it will drive the push rod 64 to move. When the push rod 64 moves, the mounting block 65 will drive the brake pad 66 to move, thereby applying braking friction to the ring 41. When the first inclined block 63 moves, it will drive the limit bar 67 to move, so that the mounting block 65 can move in a limited position, and at the same time, it will compress the first spring 68. When the limit bar 67 moves, it will drive the movable plate 10 to move. When the movable plate 10 moves, it will bring The second inclined block 11 moves. At this time, the second inclined block 11 contacts the inclined surface of the third inclined block 12. Then the third inclined block 12 drives the positioning rod 13 to move the fixed block 14. When the fixed block 14 moves, the friction ring 15 contacts the circular ring 41 to assist in braking it. When the positioning rod 13 moves, the connecting plate 16 is driven to make the limiting ring 17 squeeze the second spring 18. Thus, the circular ring 41 is braked by the two brake pads 66 and the two brake rings 42 at the same time to achieve double braking. The brake rings 42 and the brake pads 66 are both detachably connected, which can greatly improve the convenience of maintenance. No need to disassemble multiple parts for replacement.
