Abstract

A jaw-type hook self-resetting barge hook is characterized by comprising a buffer (1), a spring (2), a machine head (3), a drive device (4), a locking block (5), jaws (6) and a retractable collision head (7), wherein two jaws (6) are symmetrically installed on the machine head (3) and supported by an expansion spring (2), the retractable collision head (7) is arranged on the front end of the machine head (3), a jaw pendulum is located in a telescopic stroke of the retractable collision head (7), the locking block (5) is arranged between the symmetric jaws (6), the drive device (4) pushes the locking block (5) through a push rod, and a locking block clamping groove, the locking block (5) and the drive device (4) on the jaws (6) form a locking mechanism. The jaw-type hook self-resetting barge hook is used for substituting the traditional trolley hook of the vehicle transporting device. Due to adopting the jaw-type hook self-resetting barge hook, the manual operation is eliminated, the operation efficiency is improved, and the potential danger of the personal safety and the equipment safety accident can be avoided.

Description

Chela formula hook Self-resetting is refuted hook

Technical field

The utility model belongs to the rolling stock power tool.

Background technology

At present, unloading of railway loose unpacked material vehicle, adopt more and more the mode of rotating machinery operation to carry out, hitch articulates the position normally shown in Fig. 1 (birds-eye view), the left side is the existing go-cart hitch that send vehicle device, vehicle coupler is sent on the right, is sent between vehicle coupler and the car body connecting bore to have the gap.Yet in the rotating machinery operation, when being sent vehicle to be returned to the normal position, owing to being sent between vehicle coupler and the car body connecting bore and being had the gap, although sent vehicle to be returned to the normal position, but sent vehicle coupler usually all can not be returned to the middle of car body connecting bore, sent vehicle coupler to be offset, its offset direction is shown in Fig. 2 (birds-eye view).At this moment, because the head of the head that vehicle coupler is sent on the right and left side go-cart hitch then send the car operation because hitch can not normally articulate, and temporary transient the pause need can be carried out next task program after artificial disposal will be sent vehicle coupler centering not on a line.And the existing equipment (car puller, shunter) of sending, all adopt general hitch to articulate, sent the hitch of vehicle to need to be converted to blocking by opening, send put in place after, need again manually to be sent the hitch of vehicle to be converted to opening, can articulate the group row with other vehicle.This namely affects operating efficiency, exists again the hidden danger of the person and device security accident.

Summary of the invention

The purpose of this utility model is for above problem, proposes a kind of chela formula hook Self-resetting and refutes hook, and to substitute original go-cart hitch that send vehicle device, it can eliminate artificial disposal, improves operating efficiency, has avoided the hidden danger of the person and device security accident.

The technical solution of the utility model is: chela formula hook Self-resetting is refuted hook, it is characterized in that: comprise energy disperser, spring, head, actuator, lock dog, chela, flexible meeting and discussing, two chela symmetries are installed on the head, and the spring supporting of opening arranged, flexible meeting and discussing is positioned at the front end of head, and the chela pendulum places flexible flexible stroke of meeting and discussing, and places lock dog in the middle of the symmetrical chela, lock dog is connected with actuator by push rod, and the lock dog draw-in groove on the chela, lock dog and actuator consist of locking mechanism.

Aforesaid chela formula is linked up with Self-resetting and refuted hook, it is characterized in that: chela pendulum partial design is two pairs up and down, and the up and down pendulum connection at the chela place.Increase the stationarity that connects.

This device characteristic: after being sent vehicle coupler to reset, still keep original folding condition; Head and energy disperser are with bolts, can finely tune chela formula hook in the horizontal direction; Change meeting and discussing of different size, can satisfy and be sent the different mode of operation of vehicle coupler (left avertence, right avertence, hook unlatching, hook closure); Chela is sent vehicle coupler to contact by yielding rubber with quilt, can be to not sent the hitch injury of vehicle; Chela pendulum partial design is two pairs up and down, and the up and down pendulum connection at the chela place.

The explanation of mark among the figure: energy disperser 1, spring 2, head 3, actuator 4, lock dog 5, chela 6 stretches and meets and discusses 7, and rubber buffer circle 8 is sent vehicle coupler 9.

The specific embodiment

Referring to Fig. 3.The chela formula hook Self-resetting of the utility model embodiment is refuted hook (hereinafter to be referred as pushing equipment), it is characterized in that: comprise energy disperser 1, spring 2, head 3, actuator 4(the present embodiment is electromagnet), lock dog 5, chela 6, flexible 7, two chela 6 symmetries of meeting and discussing are installed on the head 3, and there is the spring of opening 2 to support, flexible 7 front ends that are positioned at head 3 of meeting and discussing, chela pendulum place flexible 7 the flexible stroke of meeting and discussing, and place lock dogs 5 in the middle of the symmetrical chela 6, lock dog 5 is connected with actuator 4 by push rod, the lock dog draw-in groove on the chela 6, lock dog 5 and actuator 4 consist of locking mechanism.

Principle of work:

1, after pushing equipment starts, actuator 4(electromagnet or hydraulic ram) start and lock dog 5 is mentioned, chela 6 opens under the effect of spring force, and pendulum will stretch to meet and discuss and 7 release, and the hook Self-resetting is refuted hook and is entered and articulate front state (see figure 4);

2, when being sent vehicle coupler 9 to touch flexible meeting and discussing 7 time, under the effect of being sent vehicle coupler 9 axial forces, flexible 7 the telescopic section retraction and promote the chela pendulum of meeting and discussing, chela 6 inwardly motion also produces side forces, thus the quilt that will be offset send vehicle coupler righting (see figure 5).After chela 6 closed up normotopia, lock dog 5 fell under gravity into the lock dog draw-in groove chela 6 is pinned.

3, after sending the car operation to put in place, actuator 4(electromagnet or hydraulic ram) by push rod lock dog 5 is mentioned, chela 6 flicks under the effect of spring force, does counter motion behind the pushing equipment picked up signal, and pushing equipment enters next working cycle.

After being sent vehicle coupler to reset, still keep original folding condition; Head and energy disperser are with bolts, can finely tune chela formula hook in the horizontal direction; Change meeting and discussing of different size, can satisfy and be sent the different mode of operation of vehicle coupler (left avertence, right avertence, hook unlatching, hook closure); Chela is sent vehicle coupler to contact by yielding rubber with quilt, can be to not sent the hitch injury of vehicle; Chela pendulum partial design is two pairs up and down, and the up and down pendulum connection at the chela place.
