Abstract
The invention relates to a self-locking pushing mechanism of an electric connector, which comprises a supporting frame fixed on a hook body, a guide frame, a pushing cylinder fixedly arranged on the supporting frame, the electric connector sleeved on the guide frame, and a connecting rod connected with the pushing cylinder and the electric connector, wherein the connecting rod consists of a driving shaft, a driving shaft rotating arm and a telescopic rod rotating arm; the driving shaft rotating arm and the telescopic rod rotating arm are fixedly arranged on the driving shaft; the other end of a driving shaft connecting arm is coupled with a piston rod of the pushing cylinder; the back part of the electric connector is connected with a telescopic rod; the other end of the telescopic rod is coupled with the telescopic rod rotating arm; and after the piston rod of the pushing cylinder extends out and the electric connector is normally coupled, a connection line BC of a connection point B of the telescopic rod and the electric connector and the center C of the driving shaft forms an included angle with a connection line BO of the connection point B of the telescopic rod and the electric connector and the connection point O of the telescopic rod and the telescopic rod rotating arm, and the connection line BC is higher than the connection line BO. The self-locking pushing mechanism can be locked by self and has a good using effect.
Description
Technical field
The present invention relates to guarantee in a kind of electric system that electrical cnnector is accomplished reliable guide-localization and normally connected hangs and the delivery device that separates, particularly a kind of self-locking pushing mechanism.
Background technology
The electrical cnnector delivery device is mainly used in and drives and guarantee that electrical cnnector is accomplished reliable guide-localization and normally connected hangs and separates, and delivery device mainly comprises: push annexes compositions such as cylinder composition, bracing frame composition, guide frame composition, connecting rod composition.Bracing frame is formed, the guide frame composition is fixed on the coupler body, supports electrical cnnector is installed, and electrical cnnector is seesawed along the pilot bar on the guide frame.
When hitch is in the company of treating and hangs state, push the cylinder front end and fill wind, piston rod is in retracted state, and drive link is formed and is driven electrical cnnector and moves backward, accomplishes the rainproof protecgulum of electrical cnnector and normally closes.
When hitch was even hung, the company that at first accomplishes mechanical hitch hung, after mechanical hitch connects the extension completion; The Pneumatic valve switching-over of trigger gas path control system; Its front end air draft when wind is filled in propelling movement cylinder rear end, piston rod stretches out, and drive link is formed and the drive electrical cnnector is released forward; The rainproof protecgulum of electrical cnnector is opened simultaneously, and electrical cnnector is realized connecting and hung.
When hitch decomposes, the same when the action of delivery device is waited to hang state with hitch.
Yet, lose under the situation of blast in accident when pushing cylinder, cause electrical cnnector normally to connect extension, cause fault or unknown losses.
Summary of the invention
The objective of the invention is to the shortcoming to prior art, provide a kind of and stretch out at the propelling movement cylinder piston rod, electrical cnnector has auto-lock function after normally connecting extension, can guarantee that electrical cnnector normally connects the self-locking pushing mechanism of electric connector of extension.
Technical scheme of the present invention is: a kind of self-locking pushing mechanism of electric connector; Comprise the bracing frame, the guide frame that are fixed on the coupler body; Be installed in the propelling movement cylinder on the bracing frame, be set on the guide frame electrical cnnector and with push cylinder, electrical cnnector bonded assembly connecting rod is formed; Wherein, Connecting rod is formed and is comprised transmission shaft, transmission shaft swivel arm and expansion link swivel arm, and transmission shaft swivel arm, expansion link swivel arm are installed on the transmission shaft, and the other end of transmission shaft swivel arm is coupling with the propelling movement cylinder piston rod; The rear portion of electrical cnnector is connected with expansion link; The other end of expansion link is coupling on the expansion link swivel arm, after pushing that cylinder piston rod stretches out, electrical cnnector normally connect extension, and the line BO of the line BC of expansion link and electrical cnnector point of connection B and center transmission shaft C, expansion link and electrical cnnector point of connection B and expansion link and expansion link swivel arm point of connection O; Form angle between BC and the BO, and line BC is higher than line BO.
Beneficial effect of the present invention is: the present invention is after pushing that cylinder piston rod stretches out, electrical cnnector normally connects extension; The line BO of the line BC of expansion link and electrical cnnector point of connection B and center transmission shaft C, expansion link and electrical cnnector point of connection B and expansion link and expansion link swivel arm point of connection O; Form included angle A between BC and the BO; And line BC is higher than line BO, makes the O point become mechanical dead point, and delivery device is self-locking state; Even lose under the situation of blast in propelling movement cylinder accident like this, can guarantee that also electrical cnnector normally connects extension.Have only when propelling movement cylinder piston front end has blast, the piston rod withdrawal, the rotation of interlock O point breaks away from dead center position, release self-locking.The present invention is simple in structure, and is economical and practical.

The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present invention:
A kind of self-locking pushing mechanism of electric connector; Comprise the bracing frame 1, the guide frame 2 that are fixed on the coupler body; Be installed in the propelling movement cylinder 3 on the bracing frame 1, be set on the guide frame 2 electrical cnnector 4 and with push cylinder 3, electrical cnnector 4 bonded assembly connecting rods are formed; Wherein, Connecting rod is formed and is comprised transmission shaft 5, transmission shaft swivel arm 6 and expansion link swivel arm 7; Transmission shaft swivel arm 6, expansion link swivel arm 7 are installed on the transmission shaft 5; The other end of transmission shaft swivel arm 6 is coupling with pushing cylinder 3 piston rods, and the rear portion of electrical cnnector 4 is connected with expansion link 8, and the other end of expansion link 8 is coupling on expansion link swivel arm 7; After pushing that cylinder 3 piston rods stretch out, electrical cnnector 4 normally connect extension; Expansion link 8 and line BC, expansion link 8 and the electrical cnnector 4 point of connection B of electrical cnnector 4 point of connection B and transmission shaft 5 center C and the line BO of expansion link 8 and expansion link swivel arm 7 point of connection O form angle between BC and the BO, and line BC are higher than line BO.Make the O point become mechanical dead point, delivery device is self-locking state, even lose under the situation of blast in propelling movement cylinder accident like this, can guarantee that also electrical cnnector normally connects extension.Have only when propelling movement cylinder piston front end has blast, the piston rod withdrawal, the rotation of interlock O point breaks away from dead center position, release self-locking.
