Description
Technical field:
The utility model relates to a kind of trailer mechanism hitch automatic pin pulling devices.
Background technique:
Mechanism of car is coupled by coupler device with bucket wheel owner's vehicle, realizes bucket wheel machine by the combination and separation of coupler device
Main vehicle and trailer mechanism couple and disengagement, and then complete the transformation of bucket wheel machine windrow and material extracting operation function.Current bucket wheel
Machine bucket wheel owner vehicle couple with trailer mechanism and disconnecting process in there is no trailer mechanism hitch automatic pin pulling device so that bucket
Wheel owner's vehicle and trailer mechanism couple and disconnecting process in the hitch operation that pull pin is lacked manually at the scene by personnel
Point brings personal safety hidden danger to field personnel, also reduces the working efficiency of equipment.
Utility model content:
The purpose of the utility model is to overcome existing bucket wheel owner vehicle and trailer mechanism couple and disconnecting process in will be by
Personnel carry out the problem of operating of pulling pin to hitch manually at the scene, and providing one kind can be in the connection of bucket wheel owner vehicle and trailer mechanism
The automatic pin pulling device of trailer mechanism hitch when connecing and disengage operation.
Above-mentioned purpose is realized by following technical scheme:
A kind of trailer mechanism hitch automatic pin pulling device, composition include: trailer mechanism, the trailer mechanism with from
Dynamic pin pulling out device welding, the automatic pin pulling device is pulled pin by hitch with the hitch on bucket wheel owner's vehicle and is connect, described
Automatic pin pulling device includes pedestal and second connecting rod, and one end of the second connecting rod and first connecting rod are hinged, and described second
The other end of connecting rod and the third connecting rod are hinged, and the push rod of the first connecting rod and electro hydraulicthruster is hinged, institute
The third connecting rod stated is pulled pin with the hitch and is connect by wirerope.
The trailer mechanism hitch automatic pin pulling device, the middle part of the third connecting rod be fixed on the pedestal
On first support it is hinged.
The trailer mechanism hitch automatic pin pulling device, the middle part of the first connecting rod be fixed on the pedestal
On second support it is hinged.
The trailer mechanism hitch automatic pin pulling device, the on the electro hydraulicthruster and the pedestal
Three brackets are fixedly connected.
The utility model has the advantages that
1. the utility model electro hydraulicthruster and hitch, which are pulled pin, spring reset mechanism, in bucket wheel owner vehicle and tail
After mechanism of car couples again, operator is powered off by control system to electro hydraulicthruster in operating room, and power hydraulic pressure pushes away
Dynamic device spring acts on lower return, hitch pull pin on be cased with spring, return under the action of the spring, so that trailer mechanism hitch is from opening
State is opened to closed state, guarantees the normal operation again of trailer mechanism.
The utility model is of simple structure and low cost, economic and practical, can carry out automatic pin pulling to trailer mechanism hitch,
It prevents from bringing unexpected injury to site operation personnel, improves equipment operating efficiency.
Detailed description of the invention:

Specific embodiment:
Embodiment 1:
A kind of trailer mechanism hitch automatic pin pulling device, composition include: trailer mechanism 1, the trailer mechanism with from
Dynamic pin pulling out device 2 welds, and the hitch 3 on the automatic pin pulling device and bucket wheel owner vehicle 6 is pulled pin 5 connections by hitch, vehicle
Hook and bucket wheel owner's vehicle are connect by fastening bolt 4, and the automatic pin pulling device includes pedestal 14 and second connecting rod 9, described
Second connecting rod one end and first connecting rod 8 it is hinged, the other end of the second connecting rod and the third connecting rod 10 are hinged,
The push rod of the first connecting rod and electro hydraulicthruster 7 is hinged, and the third connecting rod is pulled pin with the hitch to be passed through
Wirerope 11 connects.
Embodiment 2:
According to trailer mechanism hitch automatic pin pulling device described in embodiment 1, the middle part of the third connecting rod and fixation
First support 12 on the pedestal is hinged.
Embodiment 3:
According to trailer mechanism hitch automatic pin pulling device described in embodiment 1, the middle part of the first connecting rod and fixation
Second support 13 on the pedestal is hinged.
Embodiment 4:
According to trailer mechanism hitch automatic pin pulling device described in embodiment 1 or 2 or 3, the electro hydraulicthruster
It is fixedly connected with the third bracket 15 on the pedestal.
Working principle: the rated output thrust of electro hydraulicthruster is made of connecting rod I, connecting rod II, connecting rod III, pedestal etc.
Link mechanism by wirerope be converted into pulling force and pass to hitch pulling pin, the electro hydraulicthruster when normal operation of trailer mechanism
In off-position, trailer mechanism hitch is closed state at this time, when trailer mechanism job state to be changed, operator
Thrust output pulls up in turn after operating room gives electro hydraulicthruster power transmission, electro hydraulicthruster to be powered by control system
Hitch is pulled pin, so that trailer mechanism hitch is open state, bucket wheel owner vehicle and trailer mechanism is disengaged, and realizes bucket wheel
The transformation of machine windrow and material extracting operation function.
