Abstract
The utility model relates to an anti-falling protector of trailing elevator, wherein, an elevating platform which is trailed by a sling can move along a guide post, the sling is connected with a control rod arranged in the elevating platform, a spring is arranged between the control rod and the elevating platform, the sling force of the sling makes the spring stress deformation, and a stop block connected with the control rod and the guide post form a locking set. The anti-falling protector doesn't move when the sling force of the sling is big enough for the elevating platform, however, when a malfunction makes the sling force disappear or too small to cause the elevating platform to stall, the spring restoring position makes the control rod drive the stop block and the column to be locked. The device has the advantages of simple structure, low cost and no special installation requirement, which is particularly suitable for simple elevators and small travel elevators.
Description
The utility model relates to the fender guard of elevator, and particularly the hoist cable traction drive elevators falls lockout protection device.
If faults such as stall or hoist cable fracture take place traction drive elevators, cage or bay-lift fall then abnormally dangerous rapidly.The speed-limiting protection device that conventional elevator uses has been a kind of normalized device, and it can prevent that cage stall from falling and be safe and reliable.But the speed-limit device complex structure of elevator, it is big to take up room, and the installation position is equipped with specific (special) requirements, its cost height.This because of the restriction that required by installing space and special mounting, or because of the too high restriction of cost, is unsuitable for using this speed-limit device for many easy traction jacking systems.In addition; elevator speed governor is fast inadequately to the reaction action of stall; this is for the quite big elevator of stroke safe enough, but for the elevator of little stroke (as lifting travel less than 5 meters), the speed-limiting protection device may take place do not move bay-lift as yet and fallen ground-surface situation.Thereby this speed-limiting protection device of the also inapplicable use of little stroke lifting machine.
The purpose of the utility model is to provide a kind of simple in structurely, and volume is little, and the installation site is not had specific (special) requirements, and the fast dropproof fender guard of traction drive elevators of speed of response, so that its cost is low, applicable to simplified elevator or little stroke lifting machine.
The dropproof fender guard of elevator described in the utility model; hoist cable by bay-lift that can move along guide pillar and traction bay-lift is formed; hoist cable is connected with control stalk on being installed in bay-lift; between control stalk and the bay-lift spring is housed, is in force and deformation state at the suspension force effect lower spring of hoist cable.Backing block links to each other with control stalk, and backing block can constitute the locking pair jointly with guide pillar.
Backing block can be to carve piece, and in the gap between its insertion bay-lift and the guide pillar, it is secondary to constitute the friction-type locking; Backing block also can be a ratchet, and its ratchet that blocks on the guide pillar constitutes plug-type locking pair.
The dropproof fender guard of traction drive elevators described in the utility model, when enough suspension force were arranged, the spring between control stalk and the bay-lift was in force and deformation state.This fender guard is failure to actuate, and bay-lift can move up and down smoothly along guide pillar.When hoist cable fracture or other faults taking place bay-lift is fallen rapidly, suspension force disappears or is little of being not enough to overcome spring reset.Spring resets immediately and drives control stalk and promotes backing block and guide pillar formation locking pair, and promptly locking bay-lift can not glide.
Described device, volume is little, and is simple in structure, is installed under the table top of bay-lift, becomes one with bay-lift, need not special mounting condition, also needn't take up space in addition.Whether whether this device action only depends on exists enough suspension force, suspension force is too small or disappear in case break down, and when bay-lift not taking place as yet falling, spring is reset locking immediately, thereby its speed of response is fast, and is more direct quicker than its action of elevator speed governor.The low simple and easy winch that is applicable to that the building building use of described installation cost also is applicable to the double-decked platform formula elevator that parks a car.Certainly also be applicable to conventional lift.

Embodiment one, as Fig. 1,2
Bay-lift 5 can move up and down along guide pillar 1, and control stalk 2 is hinged on by hinge 2b under the table top of bay-lift 5, and hoist cable 3 is connected with control stalk 2, and the spring 4 of dress is a stage clip in the concave station of control stalk 2 one ends.Hoist cable 3 traction control bars 2 make stage clip 4 stress deformations.Control stalk 2 be to carve piece by guide pillar 1 one end pivotally attached backing blocks 6, carve piece 6 and insert in the gap, inclined-plane between bay-lifts 5 and the guide pillar 1.When the suspension force of hoist cable 3 disappears or little to can not stop spring 4 to reset the time, spring 4 reset make control stalk 2 an end to bottom offset, control stalk 2 is equivalent to lever, and an end moves down, and the other end upwards promotes stops 6 and promptly carves piece and upwards insert in the gap, inclined-plane and to compress with guide pillar 1 that to form locking secondary.
Should be noted that spring 4 also can be extension spring, be connected with control stalk 2 that the other end links to each other with the base plate of bay-lift 5 as Fig. 2 spring 4 one ends.
Embodiment two, as Fig. 3
With guide pillar 1 guide rail 1b is housed side by side, guide rail can be a channel-section steel, and bay-lift 5 sides are equipped with guide wheel 7 and are stuck among the guide rail 1b, can make operating elevating platform more stable, and can reduce the rigidity requirement to guide pillar 1.
Embodiment three, as Fig. 4
But the backing block 6 of parallel motion is housed in the bay-lift 5, protruding for ratchet by guide pillar one end of backing block has the inclined hole 8 that favours vertical line on the backing block 6, control stalk 2 runs through bay-lift 5 and backing block 6, roller 2a is housed on the control stalk 2, and roller 2a is in the inclined hole 8 of backing block 6.It is stage clips that control stalk 2 hypomeres are with spring 4 these springs 4, and its two ends prop up the boss 2c of control stalk bottom and the base plate of bay-lift 5 respectively.There is the ratchet of aligned apertures or ratchet 1a and backing block 6 to constitute the locking pair jointly on the guide pillar 1.When 3 pairs of control stalks 2 of hoist cable have been executed suspension force, make roller 2a on the control stalk be in inclined hole 8 tops of backing block, the ratchet of backing block 6 separates with ratchet on the guide pillar 1, bay-lift 5 can move up and down along guide pillar 1, and when suspension force disappears or little to can not stop spring 4 to reset the time, the spring 4 relative backing block 6 of pulling roller 2a that resets moves down, because of being inclined hole 8 in the backing block 6, then roller 2a imposes the component of horizontal direction to backing block 6, makes backing block 6 to guide pillar 1 direction displacement, and ratchet snaps in the ratchet and locks.
