When the present invention uses,
First steel pipe 1 of the present invention and the second steel pipe 2 literary style are solid steel pipe, actually going up inside still has multi-section to be divided into used hollow steel pipe, simply a portion structure is solid, but in order to literary style is convenient, first steel pipe and the second steel pipe are first write as solid steel pipe, concrete hollow part and solid position have a detailed description at concrete structure place.
First on the first steel pipe 1, offer multiple annular groove 3, it is provided with the annular lug 4 concentric with the first steel pipe 1 at the position of fluting, so the diameter of annular lug 4 is greater than the diameter of the first steel pipe 1, and annular groove 3 quantity has multiple, thus annular lug 4 has multiple, but when arranging, annular lug 4 diameter being middle is maximum, it is sequentially reduced to the annular lug 4 of both sides, that so design in order that meet the installation of the second steel pipe 2.
Because the collar 7 of the second steel pipe 2 is when coordinating with the first steel pipe 1, first to mate U-lag 6 with U-shaped block 8, second steel pipe 2 moves down along U-lag 6, and the fixed position of the second steel pipe 2 can select different annular groove 6 positions according to actual needs, now, due to varying in size of annular lug 4, so the diameter of the collar 7 is also different, the collar 7 selecting suitable size can pass sequentially through little annular lug 4, then move to suitable annular groove 3 place, because if the size of annular lug 4 is identical, so the collar 7 move to annular lug 4 place will by annular lug 4 stop, thus cannot pass through to next annular groove 3 place.
Annular lug 4 is just used to stop that the collar 7 passes through, thus being fixed on this position, when the collar 7 chooses suitable annular groove 3, rotate the collar 7, select suitable hole, location 5, then its collar 7 and the first steel pipe 1 are fixed by alignment pin 10, now complete the first steel pipe 1 and be connected with the second the fixing of steel pipe 2.
The present invention is primarily intended to the problem solving potential safety hazard, all there is certain danger in anything, can not safety very, and for the present invention, comparatively speaking, relatively holding accident-prone place is in the junction of the second steel pipe 2 with the collar 7, the collar 7 is blocked by annular lug 4, it is not easy to come off, but As time goes on, through long-term pressure, the corrosion exposed to the weather, it is understood that there may be the fracture at the collar 7 and the second steel pipe 2 place.
And once the collar 7 and the second steel pipe 2 rupture; fixed pulley 22 above it can first through little spring 24; second steel pipe 2 is applied pulling force upwards; second steel pipe 2 of side keeps balance corresponding thereto; guarantee that the second steel pipe 2 does not come off; the present invention first passes through the connection of steel wire rope 23 and fixed pulley 22; second steel pipe 2 is carried out the safeguard protection of the first step; when second steel pipe 2 is come off; second steel pipe 2 is applied pulling force upwards through little spring 24 by the steel pipe of its opposite side; thus keeping balance, then find steel pipe fracture when maintenance, thus being replaced maintenance.
And the effect of little spring 24 is to maintain under normal condition, second steel pipe 2 of both sides is not possessed the effect of pulling force by fixed pulley 22, thus reducing the active force to the second steel pipe 2, extend the life-span that the second steel pipe 2 is fixing, it is only when the second steel pipe 2 has downward movement tendency, little spring 24 plays a role, and at once it is carried out active force upwards.
Further, if do not found in time after the second steel pipe 2 fracture, the fixing of the second steel pipe 2 all maintains by steel wire rope 23, As time goes on, the abrasion of steel wire rope 23, add second steel pipe 2 other end do not stop rock, cause the second steel pipe 2 to come off downwards.
When second steel pipe 2 comes off downwards, being connected rope 10 1 active forces upwards of 35 alignment pins, once the active force of alignment pin 10 reduces, pop-up board 12, through the structure of the first spring 13 with rotating shaft 14, can eject at once in ejection groove 11.
Because can eject at once when losing alignment pin 10 to its active force at pop-up board 12, and the second steel pipe 2 is certain to along with alignment pin 10 is moved up when coming off, so the second steel pipe 2 is when coming off, pop-up board 12 will necessarily first eject, so that when the second steel pipe 2 comes off downwards, drop on pop-up board 12, be ejected plate 12 and stop.
During in order to ensure that the second steel pipe 2 drops on pop-up board 12, will not occur roll or do not drop out pop-up board 12, pop-up board 12 can be designed to groove shapes, when pop-up board 12 drops, drop in the groove of spill pop-up board 12, or be embedded with the first flat thin magnet 25 in the termination of the second steel pipe 2, pop-up board 12 is embedded with the second flat thin magnet 26, first flat thin magnet 25 and the second flat thin magnet 26 attract each other, and are used for ensureing to drop out pop-up board 12 when the second steel pipe 2 drops.
Further, in order to prevent the second steel pipe 2 from dropping out pop-up board 12, it is arranged over baffle plate 29 in the both sides of pop-up board 12.
And connecting and fixing of baffle plate 29 must be dismountable, so just will not stop installation and the use of the collar 7, after treating that all process steps is installed, the first steel pipe 1 be installed detachable support bar 28, then dismountable block plate 29 is installed on support bar 28.
First steel pipe 1 is connected with the vertical of the first steel pipe 1, in order to better reinforce the stability of the first steel pipe 1, be set as at the two ends of the first steel pipe 1 can mate stretch out post 30 and recessed post groove 32, rotate in recessed post groove 32 to prevent it from stretching out post 30, so using fixture block 31 to be stuck in block groove 33, avoiding it freely rotatable, thus reaching to consolidate further the effect of the first steel pipe 1, finally using scaffold climbers to connect.
Further, if workman constructs on scaffold, the danger brought to workman to prevent scaffold from coming off, further safety precautions has been done at this.
nullIt is connected with the structure of pop-up board 12，It is being connected to fixing plate 17 with rotating shaft 14，When pop-up board 12 ejects downwards，Now fix plate 17 to follow rotating shaft 14 and rotate，Connecting plate 18 is followed fixing plate 17 and is rotated，But L-shaped connecting rod 19 follow mobile in，L-shaped connecting rod 19 is simply followed and is moved over to the left，But do not change its direction，That is，Because connecting plate 18 is connected through moving fastening 20 with L-shaped connecting rod 19，The result being finally reached is，L-shaped connecting rod 19 moves over to the left，But the structure direction state before remaining on，And the snap ring 34 of the second spring 16 is stuck on L-shaped connecting rod 19，Now L-shaped connecting rod 19 is deviate from snap ring 34，The second spring 16 moment being completely stretched is caused to lose tensile force，Second spring 16 starts to stretch safety net 15，Safety net 15 becomes extended state from contraction state，And then ensure the safety of workman.
In the present invention, one end of solid first steel pipe 1 is cavity, is recessed post groove 32, and the other end is solid is stretch out post 30, and the two ends of annular groove 3 are solid, is cavity between U-shaped connecting rod 19 place and ejection groove 11, is used for making the movement of U-shaped connecting rod 19.
The present invention is when installing and use, convenient and swift, and has significantly high security performance guarantee, by the structural design of steel wire rope, pop-up board, safety net on fixed pulley, thus layer by layer it being carried out safeguard protection, adds safety and the stability of scaffold.
Being closely connected between each structural design of the present invention, it is not possible to individually compare, can not pass judgment on separately as a branch, not only structure is closely connected, and the effect reached also is transmission impact mutually, it should comprehensive from general direction assurance.
Such as, the collar and the first steel pipe, U-shaped block and U-lag, hole, location and pin-and-hole and alignment pin, annular lug and the collar, pop-up board and fixing plate, fixing plate and safety net, alignment pin and pop-up board, the first magnetic sheet and second magnetic sheet etc., all connect each other, pull one hair and move the whole body.
