T-shaped slide groove, the end of the T-shaped slider 13 is located inside the T-shaped slide groove, the T-shaped slider 13 can slide along the length direction of the T-shaped slide groove, the inner top wall of the frame block 7 is installed with a contraction spring 8, one end of the contraction spring 8 is installed with a cross plate 9, the bottom of the cross plate 9 is installed with a contact block 10, the inner bottom wall of the frame block 7 is installed with a contact switch 11, an L-shaped rod 12 is installed on one side of the cross plate 9, the side of the L-shaped rod 12 away from the cross plate 9 is installed with a T-shaped slider 13, the end of the L-shaped rod 12 is installed with a guide ring 14, the guide ring 14 is sleeved on the outside of the lifting rope 5, the position of the guide ring 14 corresponds to the position of the limit block 6, the position of the contact block 10 corresponds to the position of the contact switch 11, and an alarm 15 is installed on one side of the frame block 7.
[0029] When in use, the hook body 2 is forged with high-strength alloy steel, has high load-bearing capacity and fatigue resistance, and can work normally in a high-temperature environment (such as near a furnace or molten steel area). The lifting rope 5 is made of a steel wire rope, which is twisted from multiple strands of steel wire. It has high strength, wear resistance, corrosion resistance, and high temperature resistance, and is suitable for high-temperature environments such as metallurgy. When the electric hoist 1 is in the lifting process of winding up the lifting rope 5, the lifting rope 5 is connected to the transmission wheel 22 for driving the transmission wheel 22, which is convenient for driving the transmission wheel 22, the matching plate 3 and the hook body 2 to move upward. During the rising process, the guide ring 14 moves along the length direction of the lifting rope 5. When the lifting When the lifting height rises to a certain height, after the guide ring 14 abuts against the limit block 6, as the position of the matching plate 3 rises, the distance between the guide ring 14 and the matching plate 3 is reduced, so that the L-shaped rod 12 drives the T-shaped slider 13, the cross plate 9 and the contact block 10 to move downward, so that the T-shaped slider 13 slides along the length direction of the T-shaped slide groove, so that the contraction spring 8 is forced to contract, and the position of the contact block 10 corresponds to the position of the contact switch 11. When the contact block 10 abuts against the contact switch 11, the alarm 15 sounds to remind the surrounding staff, which plays the role of anti-top impact early warning alarm, avoids collision with the electric hoist 1, and improves practicality. Example
[0030] See also Figures 1 to 8 The utility model provides a technical solution: a metallurgical hoist hook, the outer surface of the hook body 2 is respectively installed with a fixing block 16 and a tension spring 17, the two side surfaces of the fixing block 16 are rotatably connected with a baffle 18 through an axle rod, the end of the baffle 18 away from the fixing block 16 abuts against the hook body 2, the end of the tension spring 17 away from the hook body 2 is fixedly connected to the baffle 18, and the two side surfaces of the baffle 18 are installed with a U-shaped handle 19, the U-shaped handle 19 is sleeved on the outside of the hook body 2, the position of the fixing block 16 is higher than the position of the tension spring 17, the inner wall of the matching plate 3 is respectively installed with a reinforcing rod 20 and a supporting block 21, the top of the supporting block 21 is provided with a positioning groove with the up-down direction as the depth direction, and the positioning block 2 The end of 4 is inserted into the interior of the positioning groove, the two side surfaces of the auxiliary block 23 and the interior of the matching plate 3 are provided with a slot with the left and right direction as the depth direction, the end of the block 25 is inserted into the interior of the slot, the interior of the matching plate 3 is rotatably connected with the transmission wheel 22 through an axle rod, the outer surface of the hook body 2 is rotatably connected with the auxiliary block 23 through a bearing, a positioning block 24 is installed at the bottom of the auxiliary block 23, a block 25 is installed on one side of the cover plate 4, a strip block 26 is installed on the other side of the cover plate 4, a return spring 27 is installed on one side of the strip block 26, the interior of the cover plate 4 is rotatably connected with a V-shaped stopper 28 through a shaft rod, threaded holes are opened in the interiors of the matching plate 3 and the cover plate 4, and bolts 29 are arranged inside the threaded holes.
[0031] When in use, since the hook body 2 works in a metallurgical high-temperature environment, the hook body 2 needs to be disassembled and replaced after it is damaged and deformed. The patent facilitates the replacement of the hook body 2, and the stability of the hook body 2 after replacement and installation is strong. The rope is hooked on the hook body 2, and the rope is moved to the end of the hook body 2 so that the rope abuts against the baffle 18, and then the rope is moved downward to rotate the baffle 18 with the baffle 18 and the fixed block 16 as the center of the circle, so that the tension spring 17 is forced to shrink, so that the rope enters the lower part of the internal baffle 18 of the hook body 2, and then the elastic tension of the tension spring 17 causes the baffle 18 to The end of the baffle plate 18 abuts against the end of the hook body 2, which is convenient for preventing it from falling off. On the contrary, when taking out the hanging rope in the hook body 2, there is no need to push the baffle plate 18 downward again. You only need to move the U-shaped handle 19 upward to make the U-shaped handle 19 drive the baffle plate 18 to rotate, so that the end of the baffle plate 18 is away from the port of the hook body 2, which is convenient for taking out the hanging rope in the hook body 2. When replacing the hook body 2, push the V-shaped baffle rod 28 to make the return springs 27 on both sides of the V-shaped baffle rod 28 contract or the tension is stretched, so that the V-shaped baffle rod 28 is away from the bolt 29, and then the bolt 29 is screwed out from the inside of the threaded hole, and then the cover is moved. The plate 4 is used to make the card block 25 leave the card slot, and then the hook body 2 is moved upward to make the positioning block 24 leave the positioning slot, and then the hook body 2 is moved forward or backward to make the hook body 2 move out from between the two support blocks 21, so as to facilitate the disassembly of the hook body 2. Conversely, when installing, the hook body 2 is moved to make the hook body 2 move between the two support blocks 21. When the positioning block 24 on the auxiliary block 23 is aligned with the positioning slot on the support block 21, the hook body 2 is moved downward to make the end of the positioning block 24 enter the interior of the positioning slot. When the bottom of the auxiliary block 23 abuts against the top of the support block 21, the auxiliary block 23 is in contact with the top of the support block 21. The slot on the block 23 is aligned with the slot on the matching plate 3, and the cover plate 4 is moved to insert the block 25 into the inside of the slot. When the cover plate 4 is in contact with the matching plate 3, the threaded hole on the matching plate 3 is aligned with the threaded hole on the cover plate 4. At this time, the bolt 29 is turned to tighten the cover plate 4 and the matching plate 3. After turning the bolt 29, the V-shaped stop rod 28 is loosened, and the V-shaped stop rod 28 is reset through the elastic tension or elastic contraction force of the reset spring 27, so that the V-shaped stop rod 28 is in contact with the bolt 29, limiting the position of the bolt 29, preventing the bolt 29 from loosening and falling, thereby improving the stability of the installation of the hook body 2 and improving practicality.
