Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1 to 3, the auxiliary lifting appliance for the high-temperature-resistant ferrophosphorus lifting core comprises lifting holes 2 arranged on two sides of a lifting core 1, wherein each lifting hole 2 is matched with the bottom of a lifting hook 3, the upper side of each lifting hook 3 is in sliding fit with a lifting plate 4, the top of each lifting hook 3 is fixedly connected with the bottom of a limiting disc 12, a moving block 5 is fixedly arranged on the top surface of each limiting disc 12, the moving blocks 5 are in threaded fit with screw rods 6, the internal thread directions of the two moving blocks 5 are opposite, the input end of each screw rod 6 is connected with the output end of a crank 7, and a lifting ring 8 is arranged in the middle area of each lifting plate 4. In this embodiment, when the crank 7 is rotated, the screw rod 6 can be driven to rotate, and since the moving blocks 5 are in threaded fit with the screw rod 6 and the internal threads of the two moving blocks 5 are opposite in direction, the two moving blocks 5 can be close to or far away from each other, and then the limiting disc 12 and the hook 3 are driven to be close to or far away from each other.
Preferably, a ratchet-pawl mechanism 9 is further arranged between the input end of the screw 6 and the output end of the crank 7. After the ratchet pawl mechanism 9 is arranged, the rotation of the screw rod 6 can be unidirectional, for example, when the screw rod 6 rotates unidirectionally, the two moving blocks 5 are close to each other, and finally the lifting hook 3 is close to each other and inserted into the lifting hole 2, at the moment, the screw rod 6 cannot rotate reversely, so that the lifting hook 3 cannot move out of the lifting hole 2, and the lifting hook 3 is effectively prevented from being separated from the lifting hole 2.
Preferably, the ratchet-pawl mechanism 9 comprises a ratchet 9.1 fixed at the input end of the screw 6 in a sleeving manner, the ratchet 9.1 is matched with a pawl 9.2, the pawl 9.2 is hinged to the outer side of a vertical plate 9.3, the vertical plate 9.3 is fixed at one end of the hanger plate 4, one side of the pawl 9.2 is connected with a fixing plate 9.5 through a compression spring 9.4, the fixing plate 9.5 is installed at the side of the vertical plate 9.3, and a handle 9.6 is arranged at the top of the pawl 9.2. In this embodiment, the compression spring 9.4 can press the pawl 9.2 against the surface of the ratchet wheel 9.1 to keep the pawl 9.2 non-return, when the hook 3 needs to be disengaged from the hanging hole 2, the handle 9.6 can be pulled to separate the pawl 9.2 from the surface of the ratchet wheel 9.1, and then the screw 6 can be rotated reversely to disengage the hook 3 from the hanging hole 2.
Preferably, the two sides of the hanging plate 4 are both provided with sliding chutes 10 which are in sliding fit with the upper sides of the hanging hooks 3.
Preferably, both sides of the hanger plate 4 are fixedly provided with vertical plates 9.3, and both sides of the screw 6 are limited at the inner sides of the vertical plates 9.3 through bearings 11.
Preferably, the hanging core 1 is made of graphite electrode. The original hanging core is made of cast iron, because the temperature of the ferrophosphorus is too high (more than 1500 ℃), the high-temperature resistant strength of the cast iron hanging core is not enough, the iron core is always placed in the high-temperature ferrophosphorus and is easily deformed and broken under the influence of high temperature and external force, the service life is short, the price of the iron core is high, and the material consumption cost of a workshop machine is high; the graphite electrode has a melting point higher than that of the iron core, can bear the high temperature of discharged ferrophosphorus, is less influenced by the deformation of the high temperature in use, has a longer service life, and saves the material consumption in the production process
The working principle of the embodiment is as follows:
firstly, the whole lifting appliance is lifted above a lifting core 1 through a lifting ring 8, and then the height and the angle of the whole lifting appliance are adjusted, so that the bottoms of two lifting hooks 3 can be exactly aligned to a lifting hole 2; when the crank 7 is rotated, the screw rod 6 can be driven to rotate, and because the moving blocks 5 are in threaded fit with the screw rod 6 and the internal threads of the two moving blocks 5 are opposite in direction, the two moving blocks 5 can be close to each other, so that the limiting disc 12 and the lifting hook 3 are driven to be close to each other, and finally the lifting hook 3 is close to and inserted into the lifting hole 2; at the moment, due to the non-return property of the ratchet wheel and pawl mechanism 9, the screw rod 6 cannot rotate reversely, so that the lifting hook 3 cannot move out of the lifting hole 2, and the lifting hook 3 is effectively prevented from being separated from the lifting hole 2; after the steps are completed, the hanging ring 8 can be hung on the hook of the chain block, and then the chain block is lifted and transferred to a corresponding area; when it is desired to disengage the hook 3 from the lifting hole 2, the handle 9.6 can be pulled so that the pawl 9.2 is disengaged from the surface of the ratchet wheel 9.1, and then the handle 7 and the screw 6 can be rotated in the reverse direction so that the hook 3 is disengaged from the lifting hole 2.
The above embodiments are merely preferred technical solutions of the present invention, and should not be considered as limitations of the present invention, and the features in the embodiments and the examples in the present application may be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be defined by the claims and the technical solutions described in the claims, including the technical features of the equivalent alternatives as the protection scope.
