Specific embodiment
The portable field converter valve triggering test device of the present invention includes converter valve triggering test dress
10 are set, the converter valve triggering test device 10 has tester bottom plate 1, and the tester bottom plate 1 is rectangle, in tester
A rectangle sliding sleeve 2 is respectively provided at two side positions of bottom plate 1, the rectangle sliding sleeve 2 is set along the length direction of tester bottom plate 1
It sets, each rectangle sliding sleeve 2 is connect with tester bottom plate 1 by articulated shaft 3, torsional spring 4 is designed on each articulated shaft 3, torsional spring 4 makes its right
The rectangle sliding sleeve 2 answered has the tendency that being turned out always, and it is sliding that the rectangle that can be slided up and down in it is equipped in each rectangle sliding sleeve 2
Plate 5, the top of the rectangle slide plate 5 are equipped with locating piece 6, and locating piece 6 can drop down onto the top of rectangle sliding sleeve 2, and the rectangle is sliding
It is all provided on the outside of 5 bottom of plate there are two wheel shaft 7, is equipped with movable pulley 8 on each wheel shaft 7, the outside of the rectangle sliding sleeve 2 is equipped with
Two bar shaped sliding slots 9, the location of described bar shaped sliding slot 9 is corresponding with wheel shaft 7, is equipped with square in the top of tester bottom plate 1
The width direction of shape frame 11, the rectangular frame 11 is connected with the width direction of tester bottom plate 1 by V-type bracket 12,
When each rectangle sliding sleeve 2 is perpendicular to tester bottom plate 1, the top of the rectangle slide plate 5 inside rectangle sliding sleeve 2 can be with rectangular frame
11 bottom end is in contact, and the periphery of the rectangular frame 11 is equipped with test connecting line and winds groove 13.In the V-type bracket 12
Several wire positioning devices are installed in side, and wire positioning device includes adjusting nut 102, the outside of adjusting nut 102 and V-type branch
Frame 12 connects, and the connection of 102 internal screw thread of adjusting nut adjusts screw rod 101, and the upper end for adjusting screw rod 101 connects elastic fixing clip 100.
When portable field converter valve triggering test device needs store in engineering truck, rectangle sliding sleeve is pushed first
2 rotate inward certain angle, separate the top of rectangle slide plate 5 and the bottom of rectangular frame 11, then push movable pulley 8 to
On, it is located at wheel shaft 7 at the upper end position of bar shaped sliding slot 9, movable pulley 8 is detached from ground at this time, is located at converter valve triggering test dress
10 two sides are set, the rectangular frame 11 is after the support for losing rectangle slide plate 5 and movable pulley 8, under gravity, surveys
Try instrument bottom plate 1, two rectangle sliding sleeves 2, converter valve triggering test device 10 and rectangular frame 11 to falling at ground location, at this time
Integral device has apparent reduction in longitudinal height, is stored on engineering truck convenient for storage, for being transferred to different places
The test job of converter valve.
When need with converter valve triggering test device to remove portable field from engineering truck be moved to converter valve when, can
Rectangular frame 11 is lifted up first, under the action of self-weight, rectangle slide plate 5 and movable pulley 8 move down, in torsional spring 4
Under thrust, rectangle sliding sleeve 2 is rotated outward, when rectangle sliding sleeve 2 is vertical with tester bottom plate 1, as shown in Figure 1, locating piece 6
The inside for resisting rectangular frame 11 no longer rotates rectangle sliding sleeve 2, and movable pulley 8 is on ground, is located at 1 two sides of tester bottom plate
Lower section, the rectangle slide plate 5 is that rectangular frame 11 provides support with movable pulley 8, and tester bottom plate 1 is held away from ground
State.The movable pulley 8 can be the movable pulley of major diameter, and tester bottom plate 1 is higher apart from ground, be suitable for complex road condition,
Greatly promote its passage capacity.It is recessed that the test connecting line of the converter valve triggering test device can be wrapped in test connecting line winding
It in slot 13, moves, no longer needs to look for additional space to store connecting line, when arriving at change of current valve position, just together with tester
Wiring test can be carried out, the testing time has been saved.
Since converter valve is substantially built on stilts installation during installation, ground certain distance is left, tester is to the change of current
Valve need to first check when triggering test the information such as model, the number in converter valve, and the present invention is for the ease of construction personnel's observation
The information of converter valve, can install telescopic rod 201 on tester bottom plate 1, and 201 lower end of telescopic rod connect with tester bottom plate 1, stretches
201 upper end of contracting bar installation remote control holder 202, is remotely controlled on holder 202 and installs remote control camera 203 and remote control illuminating lamp 204.It reaches
After test position, tester can first stretch telescopic rod 201, make to be remotely controlled the rising of holder 202, pass through remote control equipment or mobile phone terminal
Software adjustment is remotely controlled the angle of holder 202 and shoots the information such as model, the number of converter valve using remote control camera 203, for surveying
Examination personnel veritify, and when light is bad, opening remote control headlamp 204 can be remotely controlled by remote control equipment or mobile phone terminal software, to distant
The shooting area for controlling camera 203 carries out light filling.When tester carries out docking measurement circuit interface operation, can also open distant
Control headlamp 204 is illuminated.
The present invention in order to prevent the power supply line of remote control camera 203 and remote control illuminating lamp 204 influence movable pulley 8 folding
It is folded, the telescopic rod 201 can support to hollow structure, the power supply line of remote control camera 203 and remote control illuminating lamp 204 is spiral
Spring cable 205, helical spring cable 205 are passed through from 201 inside of telescopic rod and are connect afterwards with converter valve triggering test device 10.
Wire positioning device of the invention can clamp the conductive middle part of converter valve triggering test device, thus for conducting wire
Fixed function is played at middle part, keeps electric wire more neat, while convenient for users to being quickly found out and taking conducting wire.Adjusting of the invention
Nut 102 is combined with adjusting screw rod 101 where capable of conveniently adjusting the adjusting of screw rod 101 elastic fixing clip 100 by rotation
Highly, to facilitate the height for adjusting the fixed conducting wire of elastic fixing clip 100.
Preferably, in order to keep the folding operation of whole device more easy, distinguish in the inside of described two rectangle sliding sleeves 2
It is connect with one end of a drawstring 14, the bottom of 11 width direction of rectangular frame is equipped with pulley 15, and two drawstrings 14 are from cunning
It passes through, and is connected on same positioning ring 16 in wheel 15.Pull positioning ring 16 that can quickly roll over movable pulley 8 and rectangle sliding sleeve 2
It gathers into folds, completion can be operated in a people, convenient for more quickly throwing converter valve triggering test device when reaching change of current valve position
Enter to use.
Preferably, in order to be placed into portable field more stably in engineering truck with converter valve triggering test device, V-type
Location hook 17 is additionally provided between bracket 12, positioning ring 16 can drive drawstring 14 to be suspended on location hook 17.Positioning ring 16 hangs over positioning
When on hook 17, the folded state of rectangle sliding sleeve 2 and movable pulley 8 can be locked, it will not be due to when carrying into engineering truck
Situations such as shaking and be opened accidentally.
