Abstract
The utility model discloses a blast furnace main winch pin coupling and belongs to the technical field of blast furnace winch equipment. The blast furnace main winch pin coupling is used for avoiding the accident of skip slipping caused by fracture of a nylon rod of the pin coupling. According to the technical scheme, the blast furnace main winch pin coupling is composed of a driving end coupling half, a driven end coupling half and a pin. The whole of the pin is a cylindrical nylon rod, a through hole is formed in the center of the nylon rod along the axis of the nylon rod, and a cylindrical alloy steel core is embedded in the through hole; the through hole of the nylon rod of the pin is in interference fit with the alloy steel core. According to the blast furnace main winch pin coupling, the pin is formed in a manner that the alloy steel core is arranged in the inner hole of the nylon rod, therefore, anti-shearing capability of the pin coupling is improved, original characteristics of the pin coupling are achieved, the alloy steel core still can play a role of supporting when the nylon sleeve fractures, the accident of skip slipping caused by fracture of the nylon rod of the pin coupling is avoided, and safe operation of a skip is guaranteed. The elastic pin of the blast furnace main winch pin coupling is simple in structure, low in machining cost and significant in economic benefit.
Description
Technical field
The utility model relates to the pin coupler that a kind of blast furnace main winch uses, and belongs to the BF Hoist equipment technical field.
Background technique
The charging of blast furnace winch is the key equipment in the ironmaking production, and Main Function is that the required various raw materials of ironmaking are sent in streams to a place in the blast furnace, guarantees the normal need of blast furnace ironmaking.At work, master winch motor driving speed reducer, speed reducer lower velocity shaft connect drum rotating, and the wire rope that is wrapped on the cylinder changes the truck on the joining rails after the direction by rope sheave, and the drum rotating truck is up and down operation alternately.
At present, the speed end coupling of the master file speed reducer of most of medium and small blast furnaces adopts the fitted bolt articulation hole to connect, and installation precision was high when this connecting mode connected, and replacing is that the needed time is long.For head it off, there is unit that it is designed to the nylon pin and connects.But, because truck master winch equipment is in the working state of reciprocating operation in blast furnace is produced continuously, the nylon pin bear reciprocal shearing stress compare the one direction running pin more fatiguability, more be prone to potential safety hazard.Speed when moving in the stage casing such as truck, momentum are large, easily cause the nylon pin to cut off, and are about 20 tons and fill the truck overall weight of sintering deposit this moment, and the speed reducer band-type brake is difficult to embrace, and the downslide accident very easily occurs truck, makes fault spread.
The model utility content
Technical problem to be solved in the utility model provides a kind of blast furnace main winch pin coupler, and this pin coupler can be avoided the truck downslide accident that fractures and cause because of pin of pin coupling apparatus.
The technological scheme that solves the problems of the technologies described above is:
A kind of blast furnace main winch pin coupler, it is comprised of drive end half-coupling, driven end half-coupling, pin, and the integral body of pin is cylindrical nylon rod, along the nylon rod axis through hole is arranged at the nylon rod center, is embedded with cylindrical alloyed steel steel core in the through hole.
Above-mentioned blast furnace main winch pin coupler, the nylon rod through hole of described pin and alloyed steel steel core are interference fit.
The beneficial effects of the utility model are:
Pin of the present utility model is to install the alloyed steel steel core in the endoporus of nylon rod additional to form, improved the anti-shear ability of pin coupler, both satisfied the original characteristic of pin coupler, guaranteed that again the alloyed steel steel core still can play supporting role when nylon jacket ruptures, avoid the truck downslide accident that fractures and cause because of the pin coupler nylon rod, guaranteed the safe operation of truck.Spring column pin of the present utility model simple in structure, processing cost is extremely low, have significant economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional drawing of spring column pin.
Mark is as follows among the figure: drive end half-coupling 1. driven end half-coupling 2, pin 3. back-up ring 4, bolt 5, nylon rod 6, alloyed steel steel core 7.
Embodiment
The utility model is comprised of drive end half-coupling 1, driven end half-coupling 2, pin 3.
Show among the figure that the drive end half-coupling 1 of coupling is connected with bolt 5 by pin 3 with driven end half-coupling 2.The integral body of pin 3 is cylindrical nylon rod 6, along the nylon rod axis through hole is arranged at nylon rod 6 centers, is embedded with cylindrical alloyed steel steel core 7 in the through hole.
In reality processing, can be with the nylon rod 6 interior punchings of pin 3, and penetrate alloyed steel steel core 7.The endoporus of nylon rod 6 and alloyed steel steel core 7 should be selected interference fit, to guarantee combining closely of nylon rod 6 and alloyed steel steel core 7.
Process of the test of the present utility model:
(1) speed reducer and the test run of motor monomer
Utilize the periodical repair time, the pin coupler that newly processing is come is in place, and centering precision and coupling installation requirement reach national corresponding size pin coupler installation code; Untie low-speed shaft coupler, test run motor and speed reducer check improved high-speed coupling runnability separately.The unloaded truck of simulating moves 100 batches, is in operation and detects the Vibration Condition of coupling both sides, and monitor the sound of coupling in playing parking and speed-change process, checks coupling pin after the dry run, and indices is normal.
(2) master winch interlock test run
After the monomer test run, the test run of band truck load.Low-speed shaft coupler is connected, and the truck bringing onto load is simulated 100 batches of material loading operations, is in operation and detects the Vibration Condition of coupling both sides, and monitor the sound of coupling in playing parking and speed-change process, checks coupling pin after the dry run, and indices is normal.
