Abstract

The utility model discloses a no-kinetic-energy fall-preventing safety lock of a scaffold. The no-kinetic-energy fall-preventing safety lock comprises a lock seat and a lock body, wherein the lock body is rotatably connected with the lock seat by an installing shaft; the lock seat is provided with a stopping block; the lower part of the lock body is provided with a counterweight block; the lock body is provided with convex-outwards poking claws and lock heads; when the lock body rotates, the poking claw can abut against the stopping block; the lock seat is also fixedly connected with an anti-inclination support which is provided with four guide wheels; the lock body comprises two locking blocks and the counterweight block which are manufactured integrally; the counterweight block is positioned between the two locking blocks; and the two locking blocks are respectively provided with the convex-outwards poking claw and the lock head. The no-kinetic-energy fall-preventing safety lock of the scaffold has the advantages of simple structure, convenient for installation and use, and no need of operation of operators, so that the safety performance is improved.

Description

Scaffold does not have the anti-fall safety lock of kinetic energy

Technical field

The utility model relates to a kind of scaffold safety means, and especially a kind of scaffold does not have the anti-fall safety lock of kinetic energy.

Background technology

The highrise building scaffold generally is to adopt attachment type raise scaffold at present; Can be along with the building operations progress in building be carried out lift work, scaffold during up-down is because wanting upper and lower moves, and security performance is to need most consideration; Fall in order to prevent it suddenly; Traditional traveling stage adopts structure and the very complicated safety device of installation to guarantee that scaffold does not fall suddenly when mobile, and the safety device operational failure rate height of this complicacy is also very loaded down with trivial details, needs specific operating personnel's operation; If the human operational error installs and improperly falling proof device was lost efficacy scaffold is fallen, and causes security incident.

Summary of the invention

The purpose of the utility model be to provide a kind of simple in structure, easy to install and use, utilize self kinetic energy, need not operating personnel operation, the scaffold that improves security performance does not have the anti-fall safety lock of kinetic energy.

In order to achieve the above object, the technical scheme of the utility model is: a kind of scaffold does not have the anti-fall safety lock of kinetic energy, comprises lock and lock body; Lock body is rotationally connected through installation shaft and lock; Have stop block on the lock, the bottom of lock body has balancing weight, has the pusher dog and the tapered end of evagination on the lock body; After lock body rotated, pusher dog can offset with stop block.

Said lock also is fixedly connected with anti-inclination bearing, has four guide wheels on the anti-inclination bearing.

Said lock body comprises two lock dogs and balancing weight of processing one, and balancing weight and all has the pusher dog and the tapered end of evagination on two lock dogs between two lock dogs.

Have two end plates on the said lock, have installing hole on the lock body, installation shaft is passed installing hole, and two ends respectively with the two end plates load.

After adopting said structure, because lock is fixed on the building wall, the emergency staircase that is fixedly connected on lock body and the mobile scaffold is used, so simple in structure; And easy for installation, and when lock body did not rotate, the pusher dog on the lock body stretched between two safety poles of emergency staircase, when scaffold during at the adjustment height; Emergency staircase is also upper and lower to be moved, and lock body can rotate along with safety pole, if rotate slowly; Lock body will rely on the weight oneself of balancing weight to recover, if scaffold falls, emergency staircase will descend rapidly; Tapered end can withstand emergency staircase, and the stop block on pusher dog and the lock offsets, thereby stops the decline of emergency staircase; Therefore scaffold just stops falling, and need not operating personnel's operation, utilizes self kinetic energy to improve the security performance of whole scaffold.

The specific embodiment

The embodiment that provides below in conjunction with accompanying drawing does further detailed explanation to the utility model.

Referring to Fig. 1, shown in 2, a kind of scaffold does not have the anti-fall safety lock of kinetic energy, comprises lock 1 and lock body 2; Lock body 2 is rotationally connected through installation shaft 3 and lock 1; Have stop block 1-1 on the lock 1, the bottom of lock body 2 has balancing weight 2-1, has the pusher dog 2-2-1 and the tapered end 2-2-2 of evagination on the lock body 2; After lock body 2 rotated, pusher dog 2-2-1 can offset with stop block 1-1.

Referring to Fig. 1, shown in 2, tilt in use in order to prevent emergency staircase 5, thereby influence the security performance of the utility model; Said lock 1 also is fixedly connected with anti-inclination bearing 4; Have four guide wheel 4-1 on the anti-inclination bearing 4, four guide wheel 4-1 are divided into two pairs, lay respectively at the both sides of emergency staircase 5.

Referring to Fig. 1, shown in 2; In order to make the utility model in use; Stablize firm pinning emergency staircase 5 more; Said lock body 2 comprises two lock dog 2-2 and balancing weight 2-1 who processes one, and balancing weight 2-1 and all has the pusher dog 2-2-1 and the tapered end 2-2-2 of evagination on two lock dog 2-2 between two lock dog 2-2.

Referring to Fig. 1, shown in 2,, and make lock 1 and lock body 2 reliable installation for more firm lock 1 is fixed on the construction wall; Has two end plates 1-2 on the said lock 1; Have installing hole 2-3 on the lock body 2, installation shaft 3 is passed installing hole 2-3, and two ends respectively with two end plates 1-2 load.

When the utility model uses, lock 1 is fixed on the construction wall, lock body 2 is rotationally connected through two installing hole 2-3 of installation shaft 3 with lock 1; The bearing 4 of will preventing then tilting is fixedly connected on the lock 1, and emergency staircase 5 is passed two guide wheel 4-1 that prevent inclination bearing 4, prevents that emergency staircase 5 from tilting; Referring to shown in Figure 3, this figure is emergency staircase 5 halted state sketch mapes, and the pusher dog 2-2-1 of lock body 2 is between two safety pole 5-1 of emergency staircase 5 at this moment; If scaffold moves up, safety pole 5-1 also slowly moves up, and safety pole 5-1 will drive lock body 2 through pusher dog 2-2-1 and rotate; Whenever through a safety pole 5-1, the original position when lock body 2 will be returned to Fig. 3 through balancing weight 2-1 is if scaffold falls suddenly; Referring to shown in Figure 4, emergency staircase 5 descends rapidly, and the pusher dog 2-2-1 on the lock body 2 just drives lock body 2 quick rotation; Balancing weight 2-1 can't normally reply lock body 2 to original position, and the stop block 1-1 on pusher dog 2-2-1 and the lock 1 is tight against, the safety pole 5-1 of tapered end 2-2-2 locking this moment emergency staircase 5; Prevent that safety pole 5 from falling, therefore need not operating personnel's operation, improve the security performance of whole scaffold.
