Abstract
The utility model relates to a manual slow-descending device capable of step by step descending, which mainly consists of a supporting seat, a hand wheel, a shaft, a ratchet wheel, a control assembly cover, a control assembly box body, a control rope, a hanging basket, a lifting rope, a rope winding drum for and a control assembly, wherein the control assembly mainly consists of a pawl, a pull spring, a pin, a compression spring, a cam rotating shaft, a cam, a control rope connecting rod, a screw I and a screw II. One end of the pawl is the arc-shaped contact head, the compression spring is arranged at the other end of the pawl to push against or disconnect the ratchet wheel. One end of the pull spring is connected with the pin, and the other end of the pull spring is connected with the screw II. In an action cycle, the ratchet wheel rotates in two turns, thereby realizing the control on step by step descending. If the control rope is pulled and then loosened, the descending continues until the hanging basket reaches the needed position. The descending speed of the hanging basket can be controlled by controlling the frequency of the control rope pulling and loosening. When a rescue is completed, the hanging rope can be restored by turning the hand wheel for a next rescue.
Description
Technical field
The utility model relates to the emergency relief equipment, particularly a kind of when people need or drop to the deep-well rescue from high-rise life saving the safe and efficient reliable manual control descending lifeline that step by step descends.
Background technology
Along with being on the increase of high building and deep-well, people often run into or to drop to the deep-well from high-rise life saving and rescue, but the size of decrease speed can not be regulated, can not be suspended in the decline process in the Rescue Kits ubiquity decline process that can satisfy these class needs in the market, reliability is not high, the more high deficiency of price, goes back the market demand that the more satisfactory product of neither one can satisfy emergency relief.
Summary of the invention
In order to address this problem, the utility model provides a kind of manual control descending lifeline that step by step descends, can allow the user convenient, reliably save oneself or rescue other people.
The technical scheme that the utility model adopted is:
The manual control descending lifeline that step by step descends mainly is made of bearing, handwheel, axle, ratchet, control assembly lid, control assembly casing, control rope, hanging basket, lifting rope, rope drum and control assembly, and described control assembly mainly is made of ratchet, extension spring, pin, stage clip, cam shaft, cam, control rope connecting rod, screw I, screw II.Two installing holes are arranged on the base plate of described bearing, and there is a suspension hook centre of base plate, can utilize two installing holes to fix with screw when therefore using, and also can utilize the middle suspension hook of base plate to hang firm place with steel wire rope, uses more convenient like this.The two ends of the base plate of described bearing are connected a gripper shoe respectively with the centre.Described axle is installed in the hole of these three gripper shoes by bearing.Described axle is gone up described ratchet, described rope drum and described handwheel is installed.Described control assembly is installed above one side of the gripper shoe of the centre of the base plate of described bearing.Described ratchet one end is the circular arc contact head that contacts with described cam, and the other end is laid described stage clip and described ratchet withstood or thrown off.The two ends of described ratchet are installed in the hole of described control assembly casing both sides.Described cam is connected with the base plate of described control assembly casing by described cam shaft and can rotates around described cam shaft.One end of described extension spring is connected with described pin, and the other end is connected with described screw II.Described pin is squeezed in the upper wall of described control assembly casing, and described screw II is connected with described cam.One of described control rope is connected with described control rope connecting rod.Described control rope connecting rod is connected with described cam by described screw I.Described hanging basket hangs over the middle part of the length of described lifting rope.Two of described lifting rope is fixed on the described rope drum.Described lifting rope is on described rope drum.During use, described control rope is put down,, also can also connect two strands of control ropes, respectively by survivor and superincumbent people control by superincumbent people's control by survivor's control.This moment, described ratchet withstood described ratchet.During use, spur described control rope, described cam rotates counterclockwise around described cam shaft, when the peak of described cam contacts with the circular arc contact head of described ratchet, the circular arc contact head that promotes described ratchet outwards moves to ultimate range, thereby described ratchet and described ratchet are thrown off, described ratchet rotates, described rope drum rotates, described lifting rope lays out, and described hanging basket descends, and continues the described control rope of pulling, described cam will be rotated further up to the downside that comes to described control assembly casing and stop, the circular arc contact head of described ratchet slides to minimum point from the peak of described cam, and promote described ratchet and reset this moment under the effect of described stage clip, thereby make described ratchet withstand described ratchet, described ratchet stops operating.If this moment, the survivor was owing to reasons such as anxiety continue the described control rope of tension, described ratchet continues to withstand described ratchet, and described ratchet continues to stop operating, and described hanging basket stops to descend.If loosen described control rope this moment, described cam will clockwise rotate under the effect of described extension spring, when the peak of described cam contacts with the circular arc contact head of described ratchet, the circular arc contact head that promotes described ratchet outwards moves to ultimate range, from and described ratchet and described ratchet are thrown off, described ratchet rotates, described rope drum rotates, described lifting rope lays out, described hanging basket descends, described extension spring continues the described cam of pulling, described cam stops up to the upside that comes to described control assembly casing continuing to clockwise rotate or owing to described extension spring is got back to nature and stopped, the circular arc contact head of described ratchet slides to the minimum point of described cam opposite side from the peak of described cam, this moment is under the effect of described stage clip, promote described ratchet and reset, thereby make described ratchet withstand described ratchet again, described ratchet stops operating.So just finished an action cycle, rotated two circles at ratchet described in the action cycle.So realized the control that descends step by step.Continue pulling and unclamp described control rope then, can realize continuing to descend till arrival needs the position.Control spurs the frequency of unclamping described control rope, can control the decrease speed of described hanging basket.After finishing once rescue, described lifting rope can be resetted by rotating described handwheel, thereby can rescue next time.
The beneficial effects of the utility model are:
When people in use, the described manual control descending lifeline dependable performance, easy to use that step by step descends.The described manual control descending lifeline simple structure that step by step descends, practicality rational in infrastructure, easy to operate, can control at any time and descend or stop, the speed of decrease speed can arbitrarily be controlled, in the decline process survivor owing to nervous and when tightly dragging described control rope step by step the descend described rope drum of descending lifeline of described manual control stop operating and embodied high reliability.
