Description

Modular impact crusher

Technical Field

The invention relates to the field of crusher equipment, in particular to a modular impact crusher convenient to maintain.

Background

The impact crusher is used as a crusher for crushing materials by using an impact principle, has the characteristics of simple structure, high reliability, wide application range and the like, and is widely applied to industries such as mines, chemical engineering, buildings, railways and the like.

The inside wear-resisting part of installing of impact crusher, including welt in the frame, the impact welt on the impact frame, the board hammer on the rotor etc. the during operation strikes the wearing and tearing condition very seriously, needs often to change. The traditional method for maintaining the impact crusher is to separate the upper frame and the lower frame into a certain angle through a hinge device, and a worker enters the interior of the crusher to take out a side lining plate, an impact frame, a plate hammer and the like which need to be replaced. The side lining plates are formed by splicing the small lining plates connected by the bolts due to the structural limitation, and the parts of the side lining plates are shielded by the counterattack frame, so that the side lining plates are very inconvenient to replace. The replacement of the impact liner plate is also carried out outside the machine by taking out the whole impact frame due to the limited inner space of the machine, and the impact frame is large in volume and weight, is complex to connect with the machine frame and is difficult to rapidly disassemble and replace. The replacement of the plate hammers on the rotor also requires a large maintenance space. Because the internal space of the machine is narrow and small, potential safety hazards exist when people enter the machine.

People pay more attention to rapidness and simplicity in later-stage maintenance while pursuing the performance benefits of the impact crusher, strive to improve the comprehensive efficiency of products by means of reducing maintenance difficulty, reducing equipment downtime, quickly replacing damaged parts and the like, and improve market competitiveness.

Especially along with the development of portable crushing station, to maintaining efficiency and maintenance space's higher requirement, and the change of wearing parts is carried out to the mode that the frame was gone up in the upset of counterattack formula breaker adopted usually, and the upper frame that overturns backward can occupy originally little equipment space, has produced adverse effect to the design application of portable crushing station.

The Chinese invention patent CN105233923B discloses a structure that can integrally hang the impact frame out of the device without turning the upper frame to replace the impact lining plate. Although the upper machine frame can not be turned over any more, the impact frame and the impact frame adjusting device still need to be detached in advance, the impact lining plate can only be replaced by the structure, and the replacement of the side lining plate and the plate hammer still needs to be finished by turning over the upper machine frame.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a modularized frame type impact crusher which is easy to operate and can quickly replace vulnerable parts such as impact lining plates, side lining plates, plate hammers and the like.

The technical scheme of the invention is realized as follows:

a modularized impact crusher comprises a base, wherein a rotor part is arranged on the base, a front frame and a rear frame are detachably arranged on the base at two sides of the rotor part, openings of the front frame and the rear frame are oppositely arranged, a front side access door is arranged between the front frame and the rear frame, a front side lining plate is arranged at the inner side of the front side access door, the front side access door is symmetrically arranged on two side frames of the rear frame, rear side access doors are respectively arranged on two side surfaces of the rear frame, a rear side lining plate is arranged at the inner side of the rear side access door, an upper access door is arranged between the top of the front frame and the top of the rear frame, an upper impact frame is arranged below the upper access door, an upper adjusting device is arranged at the rear end of the upper impact frame, the front end of the upper impact frame is arranged on the front frame, the rear end of the upper impact frame is arranged on the rear frame, a lower access door is arranged on the side surface, the below of access door is provided with down the counterattack frame, and the rear end of lower counterattack frame is provided with down adjusting device, goes up the counterattack frame and all is provided with the counterattack welt with lower counterattack frame inboard, front side access door, rear side overhaul people, go up access door, lower access door and front frame, after-frame and base form inclosed breaker casing jointly.

The top of front frame be provided with crossbeam I, be provided with two at least articulated axle bed I on the crossbeam I, the front end of going up the counterattack frame sets up in articulated axle bed I, be provided with entablature and bottom end rail on the rear frame respectively, the upper portion of entablature and bottom end rail is provided with U type groove respectively, the last adjusting device of going up the counterattack frame rear end sets up in the U type inslot of the entablature of rear frame, the lower adjusting device of lower counterattack frame rear end sets up in the U type inslot of the bottom end rail of rear frame, be provided with articulated axle bed II on the rear frame of entablature below, the front end of lower counterattack frame sets up in articulated axle bed II, articulated axle bed I and articulated axle bed II structure the same, articulated axle bed I includes fixed articulated axle bed and the gland of butt joint from top to bottom, the butt joint department of fixed articulated axle bed and gland has.

The invention has the positive effects that: the traditional impact crusher frame adopts a bearing structure, steel plates are spliced, and if a large-area maintenance access hole is formed, the strength of the frame can be seriously reduced. According to the invention, the rigid front frame and the rigid rear frame which are arranged at intervals form a larger maintenance space above the rotor, and the hinged front side access door is adopted for sealing, so that the maintenance convenience of the plate hammer and the like is improved, and the side lining plate is quickly replaced outside the machine.

The modular frame type structure design is carried out on the impact crusher by combining the working characteristics of the impact crusher, all module structures can be disassembled and translated from corresponding directions, the form of the traditional steel plate splicing frame is changed, and the overall strength of the impact crusher is improved; through the frame type structural design, the counterattack frame, the side lining plate and the plate hammer on the rotor can be quickly replaced without disassembling or adjusting the front frame or the rear frame; the traditional maintenance method of the impact crusher is changed, the upper frame and the lower frame do not need to be separated, or the upper frame and the lower frame are separated to form a certain angle, and corresponding operation can be carried out only by opening a corresponding access door, so that the working space is greatly saved, and the maintenance method is more suitable for production systems with strict space requirements such as a movable crushing station and the like; the damaged side lining plate and the plate hammer can be replaced outside the cabin, so that the maintenance mode of the impact crusher is changed, and the maintenance difficulty is reduced; the impact crusher has the advantages that the impact frame and the corresponding adjusting device can be directly and integrally lifted out of the cavity of the impact crusher, the traditional step of separating the impact frame from the corresponding adjusting device is omitted, and maintenance workers can replace impact plates and other easily damaged parts very quickly and conveniently without considering the conditions of narrow space, searching for auxiliary equipment and other adverse factors, so that maintenance time is shortened, maintenance difficulty is reduced, and production efficiency is improved.
