Abstract
The utility model provides a life saving slowly rope-lowering device, which comprises a fixed plate whose lower end is provided with lifting hooks, a brake guide pulley which is fixed to the fixed plate, a movable guide wheel which is pivoted on the fixed plate, a brake handle which is connected with the movable guide wheel and a cover plate which is hinged with the fixed plate. The life saving slowly rope-lowering device is characterized in that two brake guide wheels are arranged, and are arranged on both sides of wheel faces of the movable guide wheel; the distance between the two brake guide wheels is smaller than the maximum wheel diameter of the movable guide wheel. The life saving slowly rope-lowering device has the advantages of higher bite force and high safety compared with existing techniques, and is suitable for the life saving of high buildings.
Description
The utility model relates to a kind of slow descending device in order to the lifesaving safely dropping, particularly a kind of slow descending device with higher snap-in force.
In prior art, slow descending device mainly is provided with the fixed head of drop hanger, the binding handle that is fixed in braking guide wheel on the fixed head, is positioned at movable guide wheel that braking guide wheel below and fixed head articulate, links with movable guide wheel by a lower end and forms with the hinged cover plate of fixed head.The slow descending device that different is has be by the control handgrip allow movable guide wheel near or leave the braking guide wheel, make it and rope between frictional resistance increase or reduce and control the decrease speed of slow descending device or stop to descend; Have then by the control handgrip make the brake block that is attached thereto near or leave the braking guide wheel and realize.The weak point of above-mentioned existing slow descending device is that they have only a place in order to the origin of force that increases frictional resistance between slow descending device and rope.Therefore, the frictional resistance that is produced is limited after all, in case the frictional resistance between slow descending device and the rope is not enough to support the gravity of human body, is easy to cause the slow descending device piece prompt drop of load human body to fall, and causes danger.
The purpose of this utility model is to provide a kind of higher snap-in force that has, the slow descending device that security is good at the existing defective of existing slow descending device.
Task of the present utility model realizes by this way: this slow descending device includes the fixed head that a lower end is provided with drop hanger, be anchored on the braking guide wheel on the fixed head, be articulated in the movable guide wheel on the fixed head, with the binding handle of movable guide wheel binding and the cover plate hinged with fixed head, it is characterized in that braking guide wheel is two, be arranged at movable guide wheel wheel face both sides respectively, the distance of two brakings between the guide wheels is less than the bull wheel footpath of movable guide wheel.
The operation principle of this slow descending device is such: during use rope one end is anchored on the building, allow its lower end side wheel face within a braking guide wheel wherein pass gap between this braking guide wheel and the movable guide wheel wheel face, walk around the gap of passing behind the wheel face of movable guide wheel between another braking guide wheel and the movable guide wheel wheel face, the wheel face relief rope of walking around this braking guide wheel again hangs down.When human body is hung on the drop hanger of fixed head lower end, rope is subjected to the human body weight effect to produce a pulling force, make movable guide wheel moving and on carry, its wheel face is near the wheel face of two braking guide wheels, rope is pressed from both sides, and the frictional force resistance that contacts with movable guide wheel with the braking guide wheel increases.After frictional resistance was increased to a certain degree, slow descending device did not descend.If by the hand-tight binding handle of holding of the human of lifesaving, make it close toward the fixed head aspect, movable guide wheel leaves two braking guide wheels, and rope is not produced clamping force, and the frictional resistance between rope and guide wheel just reduces, and slow descending device slowly descends.Therefore, by adjusting the grip of control handgrip, just can realize slowly falling and stopping decline.
From improvement of the present utility model and behaviour in service as seen, the origin of force that increases frictional resistance between the utility model guide wheel and rope has two, and the frictional resistance that is produced obviously increases.Therefore, compared with the prior art have high snap-in force, use safer.In addition, structure of the present utility model is also uncomplicated, makes easily.
Below in conjunction with accompanying drawing structure of the present utility model and embodiment are further described.
Fig. 1 is the state diagram of uncapping of a kind of concrete structure of the utility model.
Fig. 2 is another embodiment of the utility model state diagram of uncapping.
As shown in Figure 1, fixed head 1 is a cuboid, has a drop hanger 5 in its lower end, also is provided with a flexure strip 6 on the fixed head of drop hanger 5 upper ends, with the switching of control drop hanger 5.Movable guide wheel 2 links together with control handgrip 3, and is articulated on the fixed head 1 with the other end of movable guide wheel 2 with respect to control handgrip 4, by the lifting of the moving guide wheel 2 of control handgrip 4 adjustable regulations.A torsionspring 7 also is housed so that the resetting of movable guide wheel 2 on this drive-connecting shaft.The cross section of movable guide wheel 2 can be a large semicircle that removes the inoperative part in top, with weight reduction.Two braking guide wheels 3 are fixed in the both sides of movable guide wheel 2 barbed portion top, and the distance between two braking guide wheels 3 is less than the diameter of movable guide wheel 2.Can touch the spoke face of two braking guide wheels 3 at movable guide wheel 2 its wheel face when the drive-connecting shaft Your Majesty rotates, can have bigger space to allow rope 8 pass through when down rotating.Two braking guide wheels 3 also can remove inoperative part to reduce shared area and weight reduction.The cover plate 9 identical with fixed head 1 shape can be articulated in the upper end or the side of fixed head 1 symmetrically, cover plate 8 and fixed head 1 can be lumped together after putting on rope 9.
Fig. 2 is the structural representation of another embodiment of the utility model.This activity guide wheel 2 can be articulated on the fixed head with its center of circle for an oval-shaped wheel body, and braking guide wheel 3 is arranged at movable guide wheel 2 both sides, and its distance is less than the major diameter of movable guide wheel 2.When partly going on the wheel face of two braking guide wheels 3, the major diameter of movable guide wheel 2 just rope 9 can be clamped, and when the major diameter of movable guide wheel 2 partly goes to the wheel face that leaves braking guide wheel 3, its minor axis does not partly contact braking guide wheel 3, and rope 9 is no longer pressed from both sides, and can be free to slide.Therefore, by control handgrip 4 also can control slow descending device gliding speed and stop gliding.
The utility model is suitable for high-rise building life saving to be used.
