Description

Technical Field

[0001] The utility model relates to the technical field of brakes, in particular to a manual brake opening device. Background Art

[0002] Gantry cranes are important lifting equipment for port production and are widely used in various ports. Since lifting equipment faces sudden power outages due to power supply and other problems during operation, according to relevant regulations on special equipment, if the equipment cannot be restored in a short time after a power outage occurs, the hook with hoisting objects is prohibited from being suspended in the air for a long time, and the hoisted heavy objects must be landed in time.

[0003] Pedestrian cranes mainly complete cargo lifting through lifting, luffing and rotating mechanisms. The lifting mechanism is the main lifting and lowering work of cargo. Port cranes mainly adopt the mode of people resting but the machine continues. The equipment utilization rate is always at a high level, which leads to inevitable failure of mechanical equipment. When the entire crane does not move, if the hook is lifting cargo at this time, the cargo needs to be dropped to the ground in time.

[0004] The above device has the following defects: if the lifting brake of the equipment does not have a manual opening device, it is modified and installed with a manual opening device, resulting in the suspended object being suspended in the air for a long time, which poses a great danger. During manual operation, the manual parts are prone to rust and aging due to long-term non-use. Therefore, a manual brake opening device is proposed to solve the above problem. Utility Model Content

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a thread groove, which is opened on the outer wall of one side of the fan-shaped plate, the inner circle thread of the thread groove is connected with a thread column, the end of the thread column away from the thread groove is fixedly connected with a handle, and a positioning port is opened on the outer wall of one side of the fan-shaped plate.

[0008] As a further description of the above technical solution: the fan-shaped plate is clamped on the pin shaft, the rotating wheel passes through the outer wall on one side of the brake torque, and the rotating wheel is rotatably connected to the inner wall on one side of the brake torque through a bearing.

[0009] As a further description of the above technical solution: the arc plate is slidably connected to an outer wall of one side of the brake ear plate, and one end of the small spring away from the arc plate is fixedly connected to the top inner wall of the oil tank.

[0010] As a further description of the above technical solution: an opening and closing cover is clamped on one side of the outer wall of the oil lubricating tank, and a transparent glass plate is fixedly connected to one side of the outer wall of the oil lubricating tank.

The adjusting mechanism 9 includes an oil lubricating tank 91, and the oil lubricating tank 91 is fixedly connected to the outer wall of one side of the brake torque 11. By setting the brake torque 11, the suspended rope is released to slowly descend. The above mechanism is the existing technology and therefore no further elaboration is made. The bottom inner wall of the oil lubricating tank 91 is slidably connected to an arc plate 94, and the top outer wall of the arc plate 94 is fixedly connected to a small spring 95. By setting the small spring 95, a thrust is continuously generated on the arc plate 94.

[0025] Reference Figure 2-Figure 3 The fan-shaped plate 2 is clamped on the pin shaft 3, and the runner 4 passes through the outer wall of one side of the brake torque 11. The runner 4 is rotatably connected to the inner wall of one side of the brake torque 11 through the bearing. The arc plate 94 is slidably connected to the outer wall of one side of the brake ear plate 5. The angle of the brake ear plate 5 changes when the personnel operate and squeezes the arc plate 94, so that the lubricating liquid in the lubricating tank 91 flows out to lubricate the rotating part. The end of the small spring 95 away from the arc plate 94 is fixedly connected to the top inner wall of the lubricating tank 91. An opening and closing cover 92 is clamped on the outer wall of one side of the lubricating tank 91. The lubricating oil is filled by setting the opening and closing cover 92. A transparent glass plate 93 is fixedly connected to the outer wall of one side of the lubricating tank 91.
