The lifting appliance is suitable for lifting rolled pieces on new and old bar production lines, and has the advantages of simple structure, high collection efficiency and low cost, so the lifting appliance is wide in popularization and application range.
Description
Technical Field
The invention belongs to the technical field of self-discharging devices, and relates to a gravity type self-discharging lifting hook and a using method thereof.
Background
For bar or thread production lines, the existing hoisting of rolled pieces is carried out by manually hoisting and unloading by using a crane hook to hang a steel wire rope or a chain. With the progress of metallurgical technology, society puts higher demands on the performance of steel, which also promotes the development of a series of new steel grades, followed by the application of a series of new processes, such as: the special bar steel needs to enter the slow cooling pit for slow cooling, and the manual hanging and unloading of hooks such as the slow cooling pit has three problems of high labor intensity, poor environment and high danger due to the high temperature of a rolled piece in the prior known hoisting mode.
Disclosure of Invention
In order to overcome the defects in the prior art, the invention provides a gravity type self-unloading lifting hook and a using method thereof, which can avoid the action of manual hook unloading to improve the hook unloading efficiency and are particularly suitable for unloading places with high labor intensity, poor environment and high danger.
The technical scheme adopted by the invention for solving the technical problems is as follows: the gravity type self-discharging lifting hook comprises a lifting hook body, wherein a lifting hook end and a counterweight end are respectively arranged at two ends of the lifting hook body, and a lifting point hole is formed between the lifting hook end and the counterweight end.
Still further, the hook end has a hook that is shaped as desired.
Further, for example: the hook may be U-shaped, L-shaped, etc.
Furthermore, the hoisting point hole is a fulcrum, and the proportional relation of the torque of the two ends can be determined according to actual requirements.
Furthermore, the end head of the counterweight end is provided with a hook pulling hole, so that the hook can be used for conveniently hooking and pulling the lifting appliance under special conditions when human intervention is needed.
A using method of a gravity type self-discharging lifting hook comprises the following using steps:
the lifting point is used as the center, one end is designed to be a lifting hook end, the other end can be designed to be counterweight ends in various shapes according to the moment parameters of the lifting hook, the magnitude proportional relation of the moments of the two ends can be confirmed according to actual requirements, when the lifting hook is hung with a chain or a steel wire rope, the lifting hook end of the lifting appliance is under the lower position, when the lifting hook is an empty hook, the lifting hook is between the horizontal position and the upper end under the action of the counterweight end, when the lifting appliance is used for lifting a rolled piece to a specified position for placement, the stress of the lifting hook is smaller and smaller along with the falling of the rolled piece, and when the rolled piece is completely put down under the action of the counterweight end of the lifting hook, the.
The invention has the positive effects that:
the hoisting device changes the phenomena of high labor intensity and danger of workers and poor working environment of the workers when the existing well-known crane hoisting hook (gourd hook) is used for hoisting steel wire ropes or chains to hoist rolled stocks manually, and is particularly suitable for hoisting operations with high labor intensity, poor environment and high danger similar to the process of entering a heat-preservation pit of special steel slow cooling stocks. The lifting appliance is suitable for lifting rolled pieces on new and old bar production lines, and has the advantages of simple structure, high collection efficiency and low cost, so the lifting appliance is wide in popularization and application range.
Drawings
Fig. 1 is a schematic view of the structure of the hook of the present invention.
In the figure: 1. a hanging point hole, 2 a hanging hook end, 3 a counterweight end and 4 a hook pulling hole.
Detailed Description
The invention is further explained below with reference to the drawings and the embodiments.
Referring to fig. 1, a gravity type self-discharging lifting hook comprises a lifting hook body, wherein a lifting hook end 2 and a counterweight end 3 are respectively arranged at two ends of the lifting hook body, and a lifting point hole 1 is formed between the lifting hook end 2 and the counterweight end 3.
Furthermore, the hook end 2 is provided with a hook, and the hook is determined to be in a specific shape according to requirements.
Further, for example: the hook may be U-shaped or the like. .
Furthermore, the hoisting point hole 1 is a fulcrum, and the proportional relation of the moments at the two ends can be determined according to actual requirements.
Furthermore, a hook pulling hole 4 is formed in the end of the counterweight end 3, so that the hook can be used for conveniently hooking and pulling the lifting appliance when human intervention is needed under special conditions.
Specifically, when the lifting appliance is used, one end with a lifting point as a center is designed into a lifting hook end 2, the other end can be designed into counterweight ends 3 in various shapes according to lifting hook moment parameters, the moment proportion relation of the two ends can be confirmed according to actual requirements, when a chain or a steel wire rope is hung on the lifting hook, the lifting hook end 2 of the lifting appliance is arranged below, when the lifting hook is in an empty hook, the lifting hook is positioned between the horizontal position and the upper end under the action of the counterweight end 3, when a rolled piece is lifted to a specified position to be placed by the lifting appliance, the stress of the lifting hook is smaller and smaller along with the falling of the rolled piece, and when the rolled piece is completely placed at the counterweight end 3 of the lifting hook, the lifting hook end 2 is lifted up, so that the.
Example (a):
the slow cooling material needs to be placed into a slow cooling pit for slow cooling in a special rod process of a certain steel and iron plant in Guangdong, a traveling crane, a chain and a gourd hook are adopted for hoisting and transporting the material into the pit at the temperature of 400-; the invention can save the process of manually unhooking the slow cooling material in the slow cooling pit, reduces the labor intensity and safety risk of unhooking workers without the need of the operation of facing edges, and avoids directly facing hot waves which burn the workers.
