Description
The utility model relates to a kind of escape device, refers to a kind of lightweight parking brake braking escape apparatus especially.
Because the safe precaution measure of high building building is perfect not to the utmost at present, all kinds of high-rise life saving apparatus have been extensive use of, a kind of known high-rise life saving apparatus is arranged, usually adopt fixed point to set firmly, so must cooperate the slow bar that falls to use in addition, this configuration can not arbitrarily change, and whole device takies very large space, other has a kind of utilization successively to set up the mode of hurdle net, and this method not only influences the high building outward appearance, and easily impaired.Planting in addition is the escape device of utilizing gear, scroll bar or producing the resistance composition with the crooked pile warp brake pad of rope.Its shortcoming be whole device do not simplify, not light and handy, and can't brake repeatedly when manipulating and be reduced to the former hook fixed point of descending lifeline, so can not bring into play rapid reusable effect.
The purpose of this utility model is, a kind of escape device of lightweight parking brake braking is provided, and this installs, and not only structure is simplified light and handy and in carrying, this device can return fixed point automatically during use, and repetitive operation is used.
The purpose of this utility model is to realize by following technical scheme: parking brake braking escape device is characterized in that: comprise a casing, elasticity coiling runner, parking brake braking group, the parking brake lever is formed;
Casing is established a carrying handle in casing one side, and is equipped with a safety belt, and wall box sets firmly one and can supply the slow collar that rope passes that fall in addition;
Elasticity coiling runner, be located in the casing, elasticity coiling runner central authorities are provided with a hollow annular distance, the hole is implanted into a fixed axis, between hollow annular distance and fixed axis, be inserted in a volute spring in advance, volute spring one end contract is gone into the hollow ring inwall, other end contract is gone into the fixed axis outer wall, fixed axis is fastened on cabinet wall, be surrounded with rope on the coiling runner, one end of rope is fixed on the runner, the other end passes from the collar on the casing, and combines with the bail of hook fixture, and coiling runner one side is provided with the friction anchor ring, cooperate the braking that inserts and puts of parking brake braking group: parking brake braking group, by two brake-shoes, two fixed pulleys, one parking brake line is formed, and cabinet wall correspondingly up and down between anchor ring is respectively equipped with two brake-shoes that back-moving spring and return spring holder hook are established to rubbing, and the parking brake line is to walk around another fixed pulley that cabinet wall sets firmly again behind two fixed pulleys that set firmly of pile warp cabinet wall, parking brake line least significant end is installed on the parking brake lever, and parking brake is held tenon one end is hubbed on casing with a pin activity the outside.
Therefore: remarkable result of the present utility model is: as long as the bail of rope hooks fixture, with safety belt the human body bundle is wrapped up in, gripping on the other hand carrying handle operates parking brake simultaneously and holds tenon, can slowly descend, need only one when arriving at ground and loose one's grip, then whole box body is released can act on braking because of elasticity coiling runner and is got back to former hook fixed point.Repetitive operation is used rapidly.
Another characteristics are: whole box body is simplified lightly, is easy to carry about with one, the convenient use.
Concrete structure of the present utility model is realized by the following examples and accompanying drawing:
Fig. 1 is a stereogram of the present utility model
Fig. 2 is a structural representation of the present utility model
Fig. 3 is the combination cross section view of elasticity coiling runner among Fig. 2.
Fig. 4 is the A-A cross section view among Fig. 3
Fig. 5 is the combination schematic views of parking brake braking group and elasticity coiling runner among Fig. 2
Fig. 6 is the three-dimensional schematic views of combination of parking brake braking group and elasticity coiling runner among Fig. 2
As shown in Figure 1 and Figure 2, parking brake braking escape device, comprise a casing 1, one elasticity coiling runner 2, proficiency braking group 3 and a parking brake lever 4 compositions, casing 1 bottom lock is established the carrying handle 11 of a U-shaped, casing 1 left and right sides is fixed with a safety belt 12, the safety belt form is not limit, and is suitable for the human body bundle and wraps up in and get final product, and has one to paste cingulum 121 as shown in Figure 1 among the embodiment, wrap up in also available known hasp etc. with convenient human body bundle.Casing 1 top is provided with a collar 13 in addition.
As Fig. 3, shown in Figure 4, elasticity coiling runner 2 is the I shape ring body, central authorities are provided with a hollow annular distance 21, the hole is implanted into a fixed axis 22, be inserted in a spiral spring 23 in advance at hollow annular distance 21 and 22 of fixed axis, make spiral spring 23 1 ends 231 contracts go into hollow ring 21 inwalls, the other end 232 contracts are gone into fixed axis 22 outer walls, fixed axis 22 is fastened on the L shaped plate 24 that casing 1 inwall sets firmly (as implementing shown in the illustration, be to cooperate two sour jujube shape packing rings 251 to be locked on the L shaped plate 24) with a bolt 25, be surrounded with rope 26 on the elasticity coiling runner 2,26 1 ends of restricting are fixed on elasticity coiling runner 2 ring walls, and the other end passes with a bail 27 from the collar 13 on casing 1 top and combines.Elasticity coiling runner 2 one sides are provided with friction anchor ring 28 for the braking that inserts and puts that cooperates parking brake braking group 3.
As Fig. 5, shown in Figure 6, establish two parking brake brake-shoes 31,31 ' on friction anchor ring 28 by the spring base hook of the back-moving spring 34 of casing 1 inwall, and friction anchor ring 28 is provided with the fixedly groove of parking brake line 33, (this groove is to establish for preventing that parking brake line 33 from taking off to move, if can bestow suitably firm locking, this groove becomes to omit not to be established), this parking brake line 33 is two fixed pulleys 32,32 ' that adopt single line pile warp casing 1 inwall to set firmly, and walks around another set fixed pulley 35 of casing 1 lower inner wall more at last and is fixed on the parking brake lever 4.
One end of parking brake lever 4 is provided with the outside that pin 41 activities are hubbed at casing 1, establish a recess 42 on one side at movable pivot place in addition, making above-mentioned parking brake line 33 least significant ends is firmly to implant in it, and available another pin 43 is to prevent deviating from of parking brake line 33, when pushing this parking brake lever 4, then can spur parking brake line 33 and be and tighten, and then drive two parking brake brake(-holder) blocks 31,31 ' and press the friction anchor ring 28 of putting elasticity coiling runner 2 inwardly, promptly produce the effect that braking stops.
Utilize the composition of above-mentioned member, 26 the bail 27 of will restricting when it uses hooks fixture, and the human body bundle is wrapped up in safety belt 12, and grip U-shaped carrying handle 11 and parking brake lever 4 respectively, and then cooperate the control that unclasps of parking brake lever 4, can provide the user slowly to descend, when arriving at ground as long as unclasp smoothly, then whole box body 1 can act on because of releasing of runner 2 of elasticity coiling, and former hook fixed point is returned in braking again.Repeated the work of requiring assistance.
The described escape device of this case, 26 can adopt the splendid thin tightwire of a piece of wood serving as a brake to halt a carriage because of restricting to be set around elasticity coiling runner 2, so runner ring body itself is flat ring-type, and casing 1 is quite light and handy certainly, again its whole constitute very belong to simplify and the operation of parking brake lever simple and easy, so be easy to carry about with one, and can cooperate the need of preparing against at random, be greatly to benefit for the true tool of user's personal safety, very practical.
