Abstract
The utility model relates to overload protection and balance equipment for a breaker, which is especially suitable for jaw roll breaker and a dual chamber roll breaker. A belt pulley doubled as a balance fly wheel is sheathed on a transmission end of an eccentric shaft, and the rim of the outer side of the belt pulley is provided with a force transmission seat of which inner side is provided with a groove which is opened along the radial direction of the belt pulley of which outer side is provided with a force transmission arm which is fixedly arranged on the eccentric shaft. One end of a plate spring arranged along the radial direction of the belt pulley is arranged and fixed at the wheel hub position of the force transmission arm, and the other end is inlaid into the groove of the force transmission seat; the other end of the eccentric shaft is provided and fixed with a balance weight or the balance fly wheel. The overload protection and balance equipment for a breaker combines the overload protection and the balance into integration. The utility model has the advantages of simple structure, and reliable work. The utility model can conveniently returns to work after overload.
Description
The utility model relates to a kind of disintegrating machine overload protection and bascule, the overload protection and the bascule of specifically a kind of jaw formula or two-chamber kibbler roll.
No matter disintegrating machine of the prior art is jaw formula or two-chamber roll-type, and its overload protection and balance all adopt two covering devices.Adopt bracket as overload protection arrangement, bracket disconnects with the protection capital equipment during overload; Two big balance flywheels are installed as bascule at the eccentric shaft two ends, the inertia force that produces during the balancing equipment running.Two covering devices cause the crusher structure complexity, need more renew bracket after the fracture of overload bracket, and are not only time-consuming, waste material, and influence equipment operation rate.In addition, make because bracket is generally all cast, influenced by material, casting technique etc., functional reliability is lower.When internal flaws such as the slag of adding are arranged when bracket, may under proper working load, be cut off; And when its actual strength surpassed design strength, the back bracket that may occur again transshipping still can not be cut off, the serious consequence that causes capital equipment to damage.
The purpose of this utility model provides disintegrating machine overload protection and the bascule that can resume work easily after a kind of simple in structure, reliable operation, the overload.
The purpose of this utility model realizes by following technical solution.
A kind of disintegrating machine overload protection and bascule; has a double belt pulley of making the balance flywheel; belt pulley is sleeved on the driving end of eccentric shaft; its outer rim place is equipped with a force-transmitting seat; there is a groove of radially offering along belt pulley the force-transmitting seat inboard, and the belt pulley outside has a power transmission arm to be fixedly mounted on the eccentric shaft, and leaf spring one end that radially is provided with along belt pulley is fixed on the wheel hub of power transmission arm; the other end is bumped in the groove of force-transmitting seat, and the other end of eccentric shaft is mounted with a balance weight.
Belt pulley is the driving end that is sleeved on eccentric shaft by lining.
Groove on the force-transmitting seat is outward-dipping to the wheel hub direction by wheel rim, bottom land becomes α=9 °-30 ° of angles with plumb line, a sidewall of groove is outward-dipping, becomes β=105 °-150 ° of angles with bottom land, and leaf spring is the inclined side identical with it with the side that this sloped sidewall matches.
Force-transmitting seat is mounted on the belt pulley by bolt, is lined with the adjustment pad between force-transmitting seat and the belt pulley.
The power transmission arm radially extends near the force-transmitting seat place along belt pulley, and the end is provided with bolt hole.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation of the utility model disintegrating machine overload protection and bascule.
Fig. 2 is that the A of Fig. 1 is to partial view.
Fig. 3 is the B-B cutaway view of Fig. 1.
The utility model disintegrating machine overload protection and bascule as shown in Figure 1 and Figure 2, mainly are made of power transmission arm 1, leaf spring 2, force-transmitting seat 3, adjustment pad 4, belt pulley 5, lining 6, eccentric shaft 7 and balance weight 10.Have the moving jaw (or eccentric roller) 8 that is mounted thereon by bearing on the eccentric shaft 7, eccentric shaft 7 is installed on the frame 9 by bearing itself.The double belt pulley 5 of making the balance flywheel is sleeved on the driving end of eccentric shaft 7 by lining 6, and its outer rim place is equipped with a force-transmitting seat 3.There is a groove of radially offering along belt pulley 5 force-transmitting seat 3 inboards, and groove is outward-dipping to the wheel hub direction by wheel rim, and bottom land becomes α=15 ° angle with plumb line, and a sidewall of groove is outward-dipping, becomes β=110 ° angle with bottom land, sees Fig. 3.Force-transmitting seat 3 is mounted on the belt pulley 5 by bolt, is lined with between force-transmitting seat 3 and the belt pulley 5 to adjust pad 4.Belt pulley 5 outsides have a power transmission arm 1 to be fastened on the eccentric shaft 7 by key, and power transmission arm 1 radially extends near force-transmitting seat place, end along belt pulley bolt hole.The leaf spring 2-that radially is provided with along belt pulley 5 holds the wheel hub that is fixed on power transmission arm 1, and the other end is bumped in the groove of force-transmitting seat 3, and leaf spring 2 is the inclined side identical with it with the side that this sloped sidewall matches.The steel spring plate 2a that is shorter in length than leaf spring 2 can be set up in leaf spring 2 inboards, to increase the elastic force of leaf spring 2.The other end of eccentric shaft 7 is mounted with a balance weight 10.
During operate as normal, the power of belt pulley 5 drives eccentric shaft 7 and rotates by force-transmitting seat 3, leaf spring 2, power transmission arm 1, drives moving jaw 8 runnings, finishes broken work.In case overload, leaf spring 2 skids off groove along the sloped sidewall of force-transmitting seat 3 grooves, and the power of belt pulley 5 can't pass on the eccentric shaft 7, idle running on eccentric shaft 7.Eccentric shaft 7 is because of the stall that runs out of steam, thereby plays overload protective function.After overload is got rid of, only need rotating pulley 5, force-transmitting seat 3 is gone to the position of staggering with leaf spring 2, by the bolt that power transmission arm 1 end bolt hole is screwed into, leaf spring 2 is pressed to belt pulley 5 directions, when leaf spring 2 ends surpass force-transmitting seat 3 inboards, it is corresponding with leaf spring 2 that rotating pulley 5 makes the groove location of force-transmitting seat 3 once more, withdraw from the bolt in the power transmission arm 1 end bolt hole, leaf spring 2 is bumped in the groove of force-transmitting seat 3, can resume work.Adjust the adjustment pad 4 between force-transmitting seat 3 and belt pulley 5 spokes, just can change the size of specified limit service load.
The utility model is integrated overload protection and junction at equilibrium, and device structure is simple; Can determine nominal operation load, functional reliability height by debugging; Adopt non-failure mode to realize overload protection, reduced production cost; Can resume work easily after the overload, improve the operating rate of equipment.
