Abstract
A furnace tapping roller-table gear with counterbalance cushioning device is disclosed, belonging to a heating furnace-front tapping roller-table gear in steel rolling mill. The utility model comprises a roller-table gear frame, a roller-table gear bearing chock disposed on the roller-table gear frame, a transmission shaft which is mounted on the roller-table gear frame and driven by sprocket, and a roller-table gear disposed on the roller-table gear frame and on the drive shaft. The roller-table gear frame is provided with a fixed beam of counterbalance shaft on which a cushioning counterbalance shaft is positioned. The cushioning counterbalance apparatus articulates on the cushioning counterbalance shaft. The utility model replaces the primary springs with the gravity via natural counterbalance to avoid the problem that the springs may induce a brittle failure causing by a concussion and lose elasticity due to high temperature, thereby decreasing the failure rate of the furnace tapping roller-table gear to a minimum and ensuring a safe operation.
Description
Technical field
The utility model relates to the preceding tapping of a kind of rolling mill furnace roller-way, particularly relates to a kind of stokehold tapping roller-way of band counterweight buffer unit of energy balance steel billet impulsive force.
Background technology
On steel rolling production-line, after the steel billet in the ending discharging furnace is heated to design temperature, will then by charging roller table steel billet be delivered to the machine front roller-way again laterally sliding on the tapping roller-way of stokehold along the slope from burner under the jacking up steel machine effect.Steel billet from the burner coasting to the tapping roller-way on the time; because burner generally is not less than 1000 millimeters to the roller-way face discrepancy in elevation; the steel billet coasting must have certain speed; for this reason; people often add two to three big springs at the side wall place of tapping roller-way; the downslide impulsive force of coming the balance steel billet with the elastic force of spring, yet, spring through regular meeting because of the frequent impact brittle failure.Lose in elasticity because of temperature is too high, so the fault rate of burner tapping roller-way often exceeds other roller-way more than 10 times.
Summary of the invention
Goal of the invention of the present utility model is to overcome disadvantages of background technology, provides a kind of and replaces spring with counterweight, and fault rate is low, handling safety, the stokehold tapping roller-way of the band counterweight buffer unit of usefulness gravitational equilibrium steel billet downslide impulsive force.
Realize the foregoing invention purpose by the following technical solutions: a kind of stokehold tapping roller-way with the counterweight buffer unit, comprise roller bed frame, be installed in the roller bed bearing seat on the roller bed frame, be installed in the power transmission shaft of using chain gear transmission on the bearing block, be arranged on the roller-way that is positioned on the roller bed frame on the power transmission shaft, it is characterized in that, roller bed frame is provided with the balancer shaft built-in beam, the balancer shaft built-in beam is provided with the buffering balancer shaft, and the buffering counterweight is articulated on the buffering balancer shaft.
Owing to adopt technique scheme, compared with prior art, the utility model is that the gravity with the nature counterweight has replaced spring in the past, no longer includes the problem that spring follows the string because of impact brittle failure and Yin Gaowen, it is minimum that the fault rate of burner tapping roller-way is dropped to, handling safety.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is further described.
Referring to accompanying drawing 1, the utility model is made up of roller bed frame 4, buffering balancer shaft 6, balancer shaft built-in beam 9 etc.The supporting leg 10 that roller bed frame 4 usefulness are reinforced supports.The head of roller bed frame is installed roller bed bearing seat 2, and roller-way power transmission shaft 7 is installed in the roller bed bearing seat 2, and drive sprocket 8 is installed on the roller-way power transmission shaft 7.Roller-way 3 is positioned on the roller-way power transmission shaft 7, the top of roller bed frame 4, and the vertical space height of roller-way 3 bottoms and roller bed frame 4 is more than or equal to 1500 millimeters.Be evenly equipped with 3-5 balancer shaft built-in beam 9 on the roller bed frame 4.Install a buffering balancer shaft 6 additional in the appropriate location of balancer shaft built-in beam 9.Every is cushioned the metallic plate system buffering counterweight 5 that all articulates a up-small and down-big shape on the balancer shaft 6.Heating furnace burner blanking slope 1 is 20 degree with the angle of roller shaft 7.
When steel billet slides on the roller-way 3 along the burner slope and continues will bump against on the buffering counterweight 5 when advancing slip from heating burner, several tons of impulsive forces when buffering counterweight 5 balances steel billet by self weight of (following big) and up-small and down-big leverage power and glides.And then realization goal of the invention.
