Abstract
The invention discloses an opening adjustment and safety device of a jaw crusher. The device comprises a rack (1) and a movable jaw plate (2) of the jaw crusher, wherein the upper end of the movable jaw plate (2) is connected with the rack (1) through a hinge; a hydraulic safety device is hinged between the lower end of the movable jaw plate (2) and the rack (1). The hydraulic safety device is adopted by the safety device of the jaw crusher, is compact and is reliable in work, and non-crushed objects can be automatically discharged when the objects enter a crushing cavity and the movable jaw is automatically reset without stopping, so the increased stress of the machine is small, generally 10 percent; about 30 percent of stress of the machine is increased by the conventional wrist plate safety device.
Description
Technical field
The opening that the present invention relates to a kind of jaw crusher regulates and safeties, belongs to jaw crusher technical field.
Background technology
Jaw crusher is commonly called as Hubei Province and breaks, and forms crusher chamber by dynamic Hubei Province and quiet jaw two pieces of jaws, two jaw movements of simulated animal and complete the disintegrating machine of material crushing operation.Be widely used in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Jaw crusher completes dynamic Hubei Province plate by driven by motor bent axle and moves back and forth, the extruding between the plate of dynamic Ban Yujing Hubei Province, Hubei Province is utilized to complete the fragmentation of material, but in use dynamic Ban Yujing Hubei Province, Hubei Province plate can be worn, the size of material of being broken like this will change, for ensureing the size of broken material, jaw crusher all has opening regulating mechanism, existing opening regulating mechanism all realizes by changing dynamic Hubei Province plate, its regulative mode adopts pad adjustment opening, it regulates opening to want complete machine to quit work at every turn, mode makes it to be separated with pad for screw rod bracket seat being backed down, take out or increase pad thus realize openings of sizes, this regulative mode is very inconvenient, level can only be realized regulate, and this kind of method wastes a large amount of time and manpower.
Simultaneously jaw crusher in shattering process for preventing non-broken material from causing damage to equipment, existing jaw crusher is equipped with safeties, this device at present more adopts bracket (cast iron materials), offer hole above, to reduce section intensity, after non-broken material falls into, machine exceedes normal duty, rupture immediately, this structure disintegrating machine quit work, thus avoids the unlikely damage of machine main parts size, though can play safety effect preferably, but there is following shortcoming: 1) must work be shut down after bracket fracture, can work after replacing; 2) because bracket is casting material, the defects such as inevitable pore, trachoma, make casting strength change, and disintegrating machine, when work, does not reach toward contact the value exceeding load, and bracket just starts fracture, and the equipment that affects normally runs.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of opening easy to adjust, quick, safeties safety coefficient accurately jaw crusher opening regulate and safeties, can the deficiencies in the prior art be overcome.
Technical scheme of the present invention: the opening of jaw crusher regulates and safeties, and it comprises frame and the moving jaw plate of jaw crusher, the upper end of dynamic Hubei Province plate is connected with frame by hinge, between the lower end and frame of dynamic Hubei Province plate, be hinged with hydrostatic safety device.
The opening of above-mentioned jaw crusher regulates and safeties are, dynamic Hubei Province plate and frame are connected to hinged seat board, described hydrostatic safety device comprises oil cylinder, and the cylinder body and piston rod of oil cylinder are connected to articulated slab, and articulated slab is connected by hinge bar with hinged seat board.
The opening of aforesaid jaw crusher regulates and safeties are that the cylinder ends of oil cylinder and the end of piston rod are bolted the stage casing at articulated slab, and articulated slab and hinged seat board are the two ends of articulated slab and hinged seat board by the position, position that hinge bar is connected.
The opening of aforesaid jaw crusher regulates and safeties are, hinge bar is made up of the threaded rod of T-shaped and horizon bar, and threaded rod is connected to the center of horizon bar; Be respectively equipped with a pair hook at the two ends of hinged seat board, the horizon bar of hinge bar is connected to that hook is upper, threaded rod realizes hinged through being connected with hold-down bolt after the connector on articulated slab.
The opening of aforesaid jaw crusher regulates and safeties are, on the threaded rod of hinge bar, cover has spring, and spring is between the connector crossing articulated slab and hold-down bolt.The opening direction being arranged on a pair hook at hinged seat board two ends is reverse.
Compared with the prior art, this jaw crusher safety device adopts hydrostatic safety device, hydrostatic safety device is compact, reliable operation, non-broken thing enters crusher chamber and automatically to discharge and dynamic jaw automatically resets, and need not stop, the stress that machine is increased is little, be generally 10%, and traditional bracket safeties make machine increase by the stress of about 30%.And adopting oil cylinder to regulate, many disadvantages when well avoiding opening to regulate, regulates during opening and does not need shutdown operation, regulates openings of sizes only need regulate oil cylinder stroke, has efficient advantage fast and accurately.
Simultaneously because of the limited space between dynamic Hubei Province plate of jaw crusher and frame, being horizontally disposed with of oil cylinder is adopted to carry out regulating the size that just need meet its stroke, requirement of strength and deflection angle thereof, requirement is regulated more than meeting, the two ends of oil cylinder all be have employed articulated structure by the present invention, simultaneously in hinged process, if adopt the end of cylinder body and expansion link to carry out hinged, the stroke of its oil cylinder will be significantly limited, industrial requirements cannot be met, turn round and look at and have employed the hinged structure in two ends, if hinge point directly adopts and is rigidly connected, when broken material, unbalance stress will affect oil cylinder service life, the present invention adopts spring straining can compensate the uneven impact caused of crushing force by deflection, increase the service life of oil cylinder.
