Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment 1：
The protector of the dynamic catwalk conveying arm includes that dynamic catwalk conveys arm body 1 and jacking part, dynamic catwalk
The both sides for conveying arm body 1 are symmetrically arranged with jacking part, described jacking part by hydraulic jack 6, connecting rod 5, sliding block 8,
Top shoe 3 and safe pin rod 4 are constituted, and top shoe 3 is movably installed with by longitudinal chute 2 on dynamic catwalk conveying arm body 1, on
Safe pin rod 4 is fixed with sliding block 3, horizontal concrete chute 7 is passed through on the dynamic catwalk conveying arm body 1 of the lower section side of longitudinal chute 2
Sliding block 8 is movably installed with, connecting rod 5 is provided between sliding block 8 and top shoe 3, one end of connecting rod 5 passes through bearing pin and sliding block
8 are flexibly connected, and the other end of connecting rod 5 is flexibly connected by bearing pin with top shoe 3, the dynamic catwalk conveying arm sheet of the lower section of connecting rod 5
Hydraulic jack 6 is provided with by bearing pin on body 1, roller is provided with the piston rod of hydraulic jack 6, hydraulic jack 6 passes through roller
It is slidably connected with connecting rod 5, the middle part of the connecting rod 5 is provided with the roller groove of arc.
When tubing string is needed in the V-groove for plough under dynamic catwalk conveying arm body 1, control hydraulic jack 6 shrinks necessarily
Length, the support force of connecting rod 5 is disappeared, and top shoe 3 is moved down under self gravitation effect, in longitudinal chute 2, and connecting rod 5 is with pin
Axle is that axis rotation is moved down, while promoting sliding block 8 to be moved to the left in horizontal concrete chute 7, so safe pin rod 4 is just gradually tapered up
To the upper surface of dynamic catwalk conveying arm body 1, now connecting rod 5 and the sliding contact again of hydraulic jack 6, top shoe 3 is not
Move down again, safe pin rod 4 is ploughed under when dynamic catwalk conveys the V-groove of arm body 1 in tubing string and do not cause interference；When tubing string position
In after the V-groove of dynamic catwalk conveying arm body 1, when dynamic catwalk conveying arm will convey tubing string, control hydraulic jack 6 is stretched out,
Hydraulic jack 6 makes to slide the company of pushing up in roller groove of the roller on piston rod on connecting rod 5 by axis rotation of bearing pin
Bar 5, in the presence of connecting rod 5, sliding block 8 is in horizontal concrete chute 7 to left movement, the upward sliding in longitudinal chute 2 of top shoe 3
Safe pin rod 4 is set to reach more than the upper surface of dynamic catwalk conveying arm body 1, to prevent in transportation tubing string from power cat
Tumbled on road conveying arm body 1, improve safety coefficient during job execution.（Referring to accompanying drawing 1）
Embodiment 2：
Jacking part is made up of hydraulic jack 6, connecting rod 5, pull bar 9, top shoe 3 and safe pin rod 4, dynamic catwalk conveying
Top shoe 3 is movably installed with by symmetrically arranged longitudinal chute 2 on arm body 1, is had between top shoe 3 and longitudinal chute 2
Certain rocks gap, and top shoe 3 can not be moved down freely under gravity, and top shoe 3 is fixedly installed at the upper part with safe pin rod 4,
The bottom of top shoe 8 is equipped with pull bar 9 by bearing pin activity, and the lower section of top shoe 3 is symmetrical arranged connecting rod 5 by pin, connecting rod 5
Lower section is fixed with hydraulic jack 6, and one end of connecting rod 5 is flexibly connected with pull bar 9 by bearing pin, is set at pin 11 on connecting rod 5
There is pin chute 12, connecting rod 5 is had certain activity space at pin 11 so that occur blocking in push-and-pull top shoe 3
Firmly can voluntarily be adjusted by pin chute 12 during phenomenon.
The other end of connecting rod 5 is connected by elastic ring 10 with the piston rod of hydraulic jack 6.
When tubing string is needed in the V-groove for plough under dynamic catwalk conveying arm body 1, hydraulic jack 6 is stretched out, and makes left side
Connecting rod 5 with pin 11 for axle center rotates counterclockwise, the connecting rod 5 on right side with pin 11 for axle center rotates clockwise, in connecting rod 5
In the presence of, the pull bar 9 of the left and right sides just drives top shoe 3 to be moved downward in longitudinal chute 2, shrinks safe pin rod 4
To the upper surface of dynamic catwalk conveying arm body 1, safe pin rod 4 is set to plough under the V that dynamic catwalk conveys arm body 1 in tubing string
Interference is not caused during type groove；After tubing string has been located in the V-groove of dynamic catwalk conveying arm 1, dynamic catwalk conveying arm wants delivery pipe
During post, control hydraulic jack 6 shrink so that the connecting rod 5 in left side with pin 11 for axle center rotates clockwise, the connecting rod 5 on right side
With pin 11 for axle center rotates counterclockwise, in the presence of connecting rod 5, the pull bar 9 of the left and right sides just drives top shoe 3 vertical
To being moved upwards in chute 2, safe pin rod 4 is set to extend out to more than the upper surface of dynamic catwalk conveying arm body 1, to prevent transport
During tubing string from dynamic catwalk conveying arm body 1 on tumble, improve job execution when safety coefficient.（Referring to accompanying drawing 2）
The protector uses hydraulic control, safe and reliable, according to job requirements come jacking or Contractible safety pin rod, solves
Existing dynamic catwalk conveying arm dismisses complicated, easily failure problem without the protector of protector or installation, is oil
The transport of tubing string provides safety assurance in the operation of field.
