Description

Technical Field

[0001] The utility model relates to the technical field of boron carbide crystal block grabbing, in particular to a boron carbide crystal block grabbing device. Background Art

[0002] Boron carbide (BC) is a non-metallic composite and a superhard artificial abrasive, second only to diamond in hardness. It is widely used in military, national defense, public security, aerospace, and nuclear industries. It plays a variety of important roles, including nuclear energy control, bulletproof materials, precision grinding, and the manufacture of high-temperature, durable components. Boron carbide is produced by directly reacting a carbon source (such as graphite or carbon black) with a boron source (such as boric acid or boric anhydride) at high temperatures. Boron carbide weighs approximately 1-2 tons when it leaves the furnace, is heated above 1500 degrees Celsius, and has a diameter of approximately 1.5 meters. Therefore, a gripping device is required to move it out of the furnace.

[0003] However, the existing boron carbide crystal block grasping device has a weak clamping force when clamping and grasping the boron carbide crystal block. The boron carbide crystal block is heavy, so when the clamping force is weak, shaking occurs during transfer, which can easily cause the boron carbide crystal block to fall off the clamping component. Utility Model Content

[0024] In this embodiment, preferably, the grabbing mechanism 201 also includes a hook pulley 204 and a rotating clamp 303, the hook pulley 204 is fixedly installed on the top of the sliding frame 202, the hook pulley 204 is movably installed on the outside of the first steel cable 205, and the first steel cable 205 is fixedly installed inside the first lifter 206.

[0025] Through the above solution, the first steel cable can be slid by the hook pulley, so that when the first steel cable is tightened or loosened, it can avoid being limited by the sliding frame. The sliding frame can be moved up and down by the first lifter to drive the first steel cable to be retracted or loosened.

[0026] In this embodiment, preferably, a first assembly plate 301 is fixedly installed on the top of the first lifter 206 , the first assembly plate 301 is fixedly installed on the outside of the mounting cross bar 105 , and a first assembly screw 302 is fixedly installed on the first assembly plate 301 .

[0027] According to the above solution, the first jack can be fixedly installed by the first assembling screw penetrating the first assembling plate and connecting it to the mounting cross bar.

[0028] In this embodiment, preferably, the rotating clamp 303 is fixedly installed at the bottom end of the sliding frame 202, a steel grabbing clamp 304 is movably installed inside the rotating clamp 303, a hanging ear 305 is fixedly installed on the outside of the steel grabbing clamp 304, and a tension spring 306 is fixedly installed between the hanging ear 305 and the sliding frame 202.

[0029] According to the above scheme, the steel grabbing clamp can be installed by rotating the clamp and can be rotated. The second steel cable can be pulled by the hanging ear to tighten the opening of the steel grabbing clamp to clamp the boron carbide crystal block. The hanging ear can be pulled by the tension spring to keep the clamping mouth of the steel grabbing clamp open in a normal state.

[0030] In this embodiment, preferably, a second steel cable 401 is provided inside the hanging ear 305 , and the second steel cable 401 is fixedly installed inside the second jack 402 , and a second assembly plate 403 is fixedly installed on the top of the second jack 402 .

At this time, the first jack 206 and the second jack 402 are started to work. During operation, the first steel cable 205 is driven by the first jack 206 to be loosened and slides on the hook pulley 204 so that the sliding frame 202 is not subject to the lifting force, so that the sliding frame 202 slides in the sliding groove 106 through the sliding block 203 to drive the steel grab 304 to move downward stably. At the same time, the second steel cable 401 is driven by the second jack 402 to be loosened to prevent the steel grab 304 from being tightened. The steel grab 304 is normally tensioned by the tension spring. 306 is pulled to keep the clamp open. When the sliding frame 202 drives the clamp to slide to the top of the boron carbide crystal block, the second jack 402 works to drive the second steel cable 401 to start tightening. During tightening, the second steel cable 401 is tightened along the inside of the hanging ear 305, so that the clamp of the steel grasping clamp 304 is tightened to clamp the boron carbide crystal block. After clamping, the second steel cable 401 is further tightened by the second jack 402 and the first jack 206 drives the first steel cable 205 to tighten, so that the sliding frame 202 is driven to lift and the boron carbide crystal block is driven to be grabbed. After grabbing, the first jack 206 and the second jack 402 stop. At this time, the user can use the traction device to pull the grabbing device and drive the boron carbide crystal block to move to the designated location.
