Description
Technical field
The utility model relates to one of mine, building material machinery technical field single toggle jaw crusher overload protection dresses
It sets.
Background technique
Currently, single toggle jaw crusher is a kind of common crushing plant, it is mainly used for being crushed the rock and mine of various hardness
Stone.It is higher and higher to the output demand of crusher unit hour with mine, the enlargement of building aggregate company, therefore crusher
Gradually develop to enlargement, structure is more complicated, volume is huger, and operating condition, load-up condition are more severe, to broken
The Stability and dependability of machine requires higher.The overload protection arrangement of existing single toggle jaw crusher generallys use bracket conduct
Safety piece, bracket fracture or bending when overload, such safety device in actual operation, since bracket is located inside equipment, and
Related fittings is more, and space for maintenance is smaller, and replacement installation bracket is more difficult, it may be necessary to circumferential component or equipment are removed,
In addition, operating mechanism can't disengage with transmission system when crusher overload causes bracket to be broken, dynamic jaw is still being moved, meeting
Biggish impact is caused to equipment, frame body and inner body may be damaged.Therefore, a kind of single toggle jaw crusher mistake is developed
Carrying protective device is always new issue anxious to be resolved.
Utility model content
The purpose of this utility model is to provide a kind of single toggle jaw crusher overload protection arrangement, which will be protected
Over pulleys carried, positioned at the outside of crusher, structure is relatively simple for dangerous device installation, easy for assemble or unload quick, insurance zero
Part is safety plug, and when apparatus overload, safety plug fracture disengages operating mechanism and transmission device, avoids and cause to crusher
Impact, improves the safety and reliability of equipment.
Purpose of the utility model is realized as follows: a kind of single toggle jaw crusher overload protection arrangement, including end cap,
End cap installs bolt group, locking lid, locking lid mounting screw, connecting plate, key, axle sleeve, safety plug, and axle sleeve is mounted on crusher
In principal axis A, axle sleeve is between principal axis A and belt pulley B, the set key on axle sleeve, by key by crusher axis A, axle sleeve and
Connecting plate connection, safety plug one end is fitted into the pin hole of belt pulley B, and the safety plug other end is packed into connecting plate pin hole, end cap
It is mounted in connection plate end face, and is fixed with end cap installation bolt group, locking lid is mounted on connection with locking lid mounting screw
Plate pin hole endface.
The utility model is characterized by its structure.Its working principle is that transmission device does not connect directly with operating mechanism
It connects, is connected by safety device therebetween, the torque that motor provides passes sequentially through belt pulley B, safety plug, connecting plate, key and passes
It is delivered in principal axis A, drives the operating of crusher operating mechanism, once safety plug, because of overload breakage, above-mentioned transmission chain fails immediately, this
When belt pulley B dally, no torque is transmitted in principal axis A, and operating mechanism and transmission device disengage, and realizes insurance function.
A kind of single toggle jaw crusher overload protection arrangement compared with prior art, has that structure is simple, installing and dismounting side
Just, safety piece is light small and exquisite, and replacement is convenient, and safety plug precision is high, effectively overflow can be avoided to run, lifting crusher
The advantages that maintainability, safety, stability and reliability that raising equipment is run, mine, building materials machine will be widely used in
In tool technical field.
Detailed description of the invention
The utility model is described in detail with reference to the accompanying drawings and embodiments.
Fig. 1 is the three-dimensional assembling structure schematic diagram of the utility model.
Fig. 2 is the related components solid assembling structure schematic diagram of the utility model and single toggle jaw crusher.
Fig. 3 is that the structure of the utility model is mounted on the location drawing on single toggle jaw crusher.
Specific embodiment
Referring to attached drawing, a kind of single toggle jaw crusher overload protection arrangement, including end cap 1, end cap installation bolt group 2, lock
Tight lid 3, locking lid mounting screw 4, connecting plate 5, key 6, axle sleeve 7, safety plug 8, axle sleeve 7 are mounted on crusher axis A, axis
Set is 7 between principal axis A and belt pulley B, the set key 6 on axle sleeve 7, by key 6 by crusher axis A, axle sleeve 7 and connecting plate
5 connections, 8 one end of safety plug is fitted into the pin hole of belt pulley B, and 8 other end of safety plug is packed into 5 pin hole of connecting plate, and end cap 1 is pacified
On 5 end face of connecting plate, and fixed with end cap installation bolt group 2, with locking lid mounting screw 4 by 3 company of being mounted on of locking lid
5 pin hole endface of fishplate bar.
A kind of working principle of single toggle jaw crusher overload protection arrangement is that transmission device and operating mechanism are not
It is directly connected to, is connected by safety device therebetween, the torque that motor provides passes sequentially through belt pulley B, safety plug 8, connection
Plate 5, key 6 are transmitted in principal axis A, drive the operating of crusher operating mechanism, once safety plug 8 is because of overload breakage, above-mentioned transmission chain
It fails immediately, belt pulley B dallies at this time, and no torque is transmitted in principal axis A, and operating mechanism and transmission device disengage, and realizes and protects
Dangerous function.
