Embodiment Construction
[0014] Such as figure 1 The block type safety brake shown is suitable for the reel device 6 on construction machinery, hoisting machinery, mining machinery, hoist and hoist, etc., and is installed on both sides of the reel device 6. The block type safety brake has a support base 1 and a support frame 2, a brake disc 3 is installed on the support base 1, and a brake assembly 4 for controlling the brake disc 3 is installed on the support frame 2.
[0015] Such as figure 2 As shown, a disc-type self-locking device 5 is installed on the brake assembly 4, and the brake assembly 4 includes a sliding seat 41 symmetrically distributed on both sides of the brake disc 3, a block 42 slidably installed on the sliding seat 41, and a block located on the block. The solenoid valve 43 at the bottom of the block 42 and used to control the operation of the block 42 and the friction plate 44 between the brake disc 3 and the block 42 . Wherein the included angle between the friction plate 44 a...

The invention relates to the technical field of brakes, in particular to a building-block-type safety brake comprising a supporting holder and a supporting rack. A break disc is mounted on the supporting holder, a brake component used for controlling the brake disc is mounted on the supporting rack, and a disc-type self-locking device is mounted on the brake component. The brake component comprises sidling seats, building blocks, an electromagnetic valve and friction sheets; the sidling seats are symmetrically distributed on two sides of the brake disc, the building blocks are mounted on the sliding seats in a sliding manner, the electromagnetic valve located at the bottoms of the building blocks is used for controlling the same to operate, and the friction sheets are located between the brake component and the building blocks. The building-block-type safety brakes are adaptable to roll devices of engineering machinery, lifting machinery, mining machinery, winches, hoists and the like and are mounted on left and right sides of the roll device, when operating brake of the roll device is in failure, the building-block-type safety brakes are capable of entering operating state immediately, and a rope, a hanging hook on the rope and a workpiece which are wrapped on the roll are effectively prevented from free falling due to own weights.
Description
technical field [0001] The invention relates to the technical field of brakes, in particular to a block type safety brake. Background technique [0002] Large-scale equipment such as construction machinery, hoisting machinery, mining machinery, winch and hoist plays a pivotal role in various industries. The reel device is one of their important components. For safety reasons, the reel device will be equipped with a working brake However, the phenomenon of failure often occurs in the existing working brakes, so that the cables wound on the reel, the suspension hooks on the cables and the workpieces are free-falling due to their own weight, which is easy to cause safety accidents. [0003] The original working brake relies on the pressure of the spring to ensure the required torque of the brake. The size of the spring pressure determines the size of the torque. The brake is disengaged through the hydraulic pump station and the oil cylinder to compress the spring, and the brake...
