Description
Technical field
The utility model relates to a kind of quick connector of engineering machinery, and especially a kind of excavator that is used for is changed the connecting rod type quick connector that the operation frock is used.
Background technology
The tradition excavator bucket, quartering hammer, it is directly to be connected with the connecting rod and the forearm of excavator that hydraulic pressure such as cuts at frock, it can only carry out one-side operation, need constantly to change the position of excavator and will dismantle bucket spindle and could change the operation frock, so inefficiency, in order to enlarge the scope of application of excavator, people adopt quick connector to connect, existing quick connector structural shape mainly contains fluid pressure type and mechanical type two big classes: fluid pressure type is to drive corresponding mechanism by hydraulic cylinder works to realize being connected and separating of operation frock, but need on existing equipment, increase corresponding pipeline and control system, because the space of little tonnage connector self is little, do not have enough spaces that hydraulic cylinder is set, and system complex and cost cost are higher; Mechanical connector adopts spring locking mode to design usually, owing to be subjected to the restricted spring power of manpower unlocking force can not be too big, causes the hypodynamic situation of locking, causes latch hook loosening to the frock case accident easily.
The utility model content
The purpose of this utility model is to provide a kind of cost low, safety, is applicable to the connecting rod type quick connector that is used for excavator of all tonnage excavators.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of connecting rod type quick connector that is used for excavator, comprise main hook body and latch hook, latch hook and main hook body are hinged, in the main hook body, be provided with linkage and strip dog, one end and the main hook body of linkage are hinged, the other end and latch hook are hinged, below linkage, be provided with limiting plate, be provided with the compression spring above, described strip dog and main hook body are hinged, and are connected on the main hook body by extension spring, be provided with the projection that groove adapts that colludes with strip dog in a side of latch hook, also be provided with the safety pin device on the main hook body, this safety pin device lateral is installed on the main hook body, and its safety pin that stretches out retaining is on latch hook closure state linkage.
The groove that colludes of described strip dog is a U type groove, and pairing projection is columned pin.
Described latch hook is one, and linkage and latch hook are hinged.
On the connecting rod of the linkage that is connected with described latch hook, be provided with the convenient shifting block of opening latch hook.
The axis of linkage became 7 ° of positions with latch hook restraint forces axis when described limiting plate was provided in a side of the latch hook closure state.
After the utility model adopts said structure, by linkage and strip dog are set in the main hook body, one end and the main hook body of linkage are hinged, the other end and latch hook are hinged, below linkage, be provided with limiting plate, be provided with the compression spring above, described strip dog and main hook body are hinged, and be connected on the main hook body by extension spring, be provided with the projection that groove adapts that colludes with strip dog in a side of latch hook, also be provided with the safety pin device on the main hook body, this safety pin device lateral is installed on the main hook body, and its safety pin that stretches out retaining is on latch hook closure state linkage.So the utility model retrains latch hook by linkage; Limiting plate below the connecting rod can not move downward connecting rod again, and the safety pin device stretches out retaining on linkage because of spring action during the latch hook closure state, and connecting rod can not be moved upward, and linkage becomes self-locking state, and latch hook is by locked; When changing frock, pulling out safety pin earlier prizes shifting block latch hook is opened with pulling handle again, the operation frock breaks away from latch hook because of the action of gravity bucket spindle, continue to prize latch hook downwards, the colluding groove and can tangle pin on the latch hook of strip dog, make latch hook stay open state, this moment, the strip dog front end can be given prominence at the U of main hook body type groove end face, the safety pin device is just in time blocked by the connecting rod pair, because of being housed in the safety pin device, the compression spring make it be in state to be stretched, make the connector main hook break away from frock when continuing operating equipment, finished the separation process of operation frock and equipment, this moment, quick connector was in state to be connected.The utility model is only with pulling handle with regard to replaceable frock, change efficient thereby improve, fluid pressure type connector system complexity, cost height have been broken through, only suitable large-tonnage excavator uses, spring connector restricted spring power can not be too big, cause the hypodynamic situation of locking, cause the problem that latch hook is loosening even frock comes off easily.
