Guard bar device when in use, device is transported and is placed at subway foundation pit, makes mounting plate 1 and ground face contact, because
For coming into contact in a large area for mounting plate 1 and ground, so that the frictional force of mounting plate 1 Yu ground is increased, to make the branch of mounting plate 1
Support is more stable, and subsequent use is safer, and guard bar device starts plate 2 obliquely in doing isolation use process, from
And start rope 5 is made to be in tight state, and 15 rear end of adjusting gear rack is contacted with start rope 5, and front end skids off and adjusts mouth 14, from
And by 16 compressional deformation of stretch cord, therefore stretch cord 16 is in energy storage state at this time, taps bar 11 and is in heeling condition, guardrail dress
It sets and isolating and protecting is carried out to foundation pit, personnel is avoided to cause danger close to foundation pit；
And when there is personnel close to foundation pit, it needs that shield could be being crossed over close to personnel close to foundation pit across guard bar device
When column device, need to trample starting plate 2, starting plate 2 rotates after being trampled and in telescoping tube 3 and telescoping tube 3
Reset spring 4 is squeezed, and starts plate 2 after rotating, start rope 5 becomes relaxed state from tight state, to lose
To the restraining force of adjusting gear rack 15, adjusting gear rack 15 at this time by stretch cord 16 elastic force and push adjusting gear rack 15 adjusting mouth
Sliding in 14, for adjusting gear rack 15 in sliding, adjusting gear rack 15 engages adjustment gear 13 to make adjustment gear 13 drive and adjust
Axis 10 rotates, and adjustment axis 10 drives in rotation to be tapped bar 11 and rotate, to make to tap bar 11 from heeling condition to vertical state
Rotation, to make rattle balls 12 be in contact with tapping board 8, because the metal material of rattle balls 12 and tapping board 8 is generate
The metal bump sound of percussion warns to close to personnel, while making knock to construction personnel to prompt, convenient to check in time
Situation；
While trampling starting plate 2 close to personnel makes percussion bar 11 carry out tapping warning to tapping board 8, start plate 2
On extruding gasbag 17 be activated the extruding of plate 2 Yu mounting plate 1, to be inflated by gas tube 23 to gas cell 22,
And after 22 inflation of gas cell, gasket 21 is squeezed in water storage shell 19, make gasket 21 in water storage shell 19 to
Water in water storage shell 19 is passed through spray head 20 outwardly against so that moisture be made to spray in upward sliding by upper sliding, gasket 21
Warned to close to personnel with physics, prevent the continuation of personnel close and cause damages；
After close personnel, which are warned, to be withdrawn from starting plate 2, starting plate 2 will be started plate 2 by the elastic force of reset spring 4
Again pushed home and run-off the straight, so that start rope 5 be made to be in tight state again, and start rope 5 is when occurring tight, will
Adjusting gear rack 15 pushes back again adjusts origin-location in mouth 14, squeezes adjusting gear rack 15 to stretch cord 16 and shape occurs
Become, while adjusting gear rack 15 engages adjustment gear 13 during being slided by thrust and rotates backward, to make 10 band of adjustment axis
The dynamic bar 11 that taps rotates backward, and tilts percussion bar 11 again and is detached from tapping board 8, facilitates guard bar device in someone
Member can continue to use when being again adjacent to foundation pit and regenerate knock and warn to personnel, in starting 2 run-off the straight of plate
While, extruding gasbag 17 is not under compression and resets, and gas cell 22 positions after inflation, so that sealing-plug be determined
Position, avoid causes next time in use, the water in water storage shell 19 can not be from spray head 20 because of not knowing for sealing-plug position
It sprays, facilitates next use；
Above-mentioned extruding gasbag 17 is traditional unidirectional air bag, and gas cell 22 is traditional elastic balloon, so as to
Squeeze extruding gasbag 17 constantly to gas cell 22, and after gas cell 22 is expanded because gas can not be discharged depending on
Position.
