Description
Technical field
The utility model relates to a kind of safety device, the hitch of the safety hook that especially a kind of work high above the ground person uses, specifically a kind of hook that can make sealing hook automatic turning obstacle-overpass.
Background technology
As everyone knows, existing safety belt is the security protection articles for use of a kind of " normality is standby ".During work, operator is enclosed within the sliding Falling that firmly makes provision against emergencies on cross bar (fixed bar) by fastened the safety belt hook with the state of " annular enclosed ".Facts have proved, it is effective to protection operator personal safety.; it also has obvious shortcoming: the equipment of this " normality is standby " has but hindered operator's freedom of movement " normality reality "; reason is extremely simple: can although for the cross bar that entangles seat belt hanger firm may long enough, can cover whole scope of operations; but the strength and stability in order to ensure cross bar; every not several meters just must be welded with a connecting rod (obstacle bar), many this little T character form structures have been cut into a lot of segments by cross bar.Operator does not move left and right several meters, and the hook of " annular enclosed " state just will inevitably be encountered this connecting rod and cannot cross, if now again manually do not untied and the hook of colligation safety belt again, just cannot pass through.That is to say, operator's free scope of activities is actual be limited in very little one by one segment within.
This shortcoming is at the working environment that only need ascend a height once in a while, the time is not urgent, job area is less, and problem is little.If crewman often need to often need to mobile working, the employee of petroleum chemical enterprise often need to move and save operation from damage the gun wale mobile working that waves whipped up by the wind rolled turbulently, the personnel that control that are correlated with on stadiums top on larger hydrocarbon tank deck, shortcoming is just obvious: if they entangle safety belt in accordance with regulations at any time firm, make provision against emergencies, just must three or five steps pauses once, manually adjust previous operation again behind seat belt hanger position, practical work efficiency will obviously reduce; If adopted a casual attitude, do not entangle safety belt firm, security risk obviously strengthens.Correlation study shows, the overwhelming majority does not entangle safety belt firm in accordance with regulations person, and the indifferent just aspect of inherently safe consciousness, the extremely important aspect of another one, is to be reluctant that the safety belt of " being only standby " too limits the freedom of movement of " normality reality ".
Lift again a more extreme example: if operator is on professional lifeboat, just fulfils lifesaving responsibility in stormy waves, in the face of this undue restriction very easily faces a difficult selection: do not entangle safety belt firm, self is extremely dangerous, rules and regulations are not allowed; And entangle " freedom of movement " and " operating efficiency " that safety belt is sacrificed firm, may not only concern economic interests but may concern the last hope that other people are rescued.
In brief, " annular enclosed " structure of existing safety belt and cross bar " connection segment " structure, be all definitely essential, and " subsection connecting structure " is real barrier for " annular enclosed structure ".The barrier that " annular enclosed " structure of existing safety belt cannot be crossed exist actually is automatically a shortcoming, is necessary to be improved.
Summary of the invention
The purpose of this utility model is for existing seat belt hanger, when running into obstacle bar, need to take off hook to surmount obstacles that again hook to be hung on fixed bar to existing operation after bar inconvenient, the problem of restriction operator displacement, design a kind of hook, this hook energy automatic turning obstacle-overpass bar, only need hang over sealing on hook and can realize the automated movement within the scope of fixed bar during use.
The technical solution of the utility model is:
A kind of hook that can make sealing hook automatic turning obstacle-overpass, it is characterized in that it comprises a sliding sleeve 1 with opening matching with the non-circular fixed bar that seals hook for hanging, upper end at sliding sleeve 1 openend is provided with rotatable parts 2, on these rotatable parts 2, being provided with can be with its rotation spaced apart, be used for the swingle of opening Dynamic Closed 3, when moving to obstacle location place, sliding sleeve 1 must have a swingle 3 by obstacle, blocked and the opening on sliding sleeve is sealed, the first leaping over obstacles of another adjacent swingle, by the swingle 3 of obstacle gear along with turning the obstacle that is rotated away from that stops parts, the swingle of this bright leaping over obstacles turns to obstacle place and replaces last rotation root to seal sliding sleeve opening, so repeat, until sliding sleeve is pulled away from obstacle, on described sliding sleeve 1, be provided with the hooking structure 4 that mounts sealing hook.
The bottom of described sliding sleeve 1 openend is provided with a stop 5 with slot, the described swingle 3 arbitrary moment in rotation process being arranged on rotatable parts 2 has the lower end of at least in the slot of described stop, to prevent that swingle is subject to occuring bending and deformation or fractureing and make sliding sleeve depart from non-circular fixed bar with the active force impact in the same way of rotatable parts axle center.
One end hinge of the mounting rod 6 of described sliding sleeve 1 open lower end mounting limit device 5 is contained in sliding sleeve main body, and is positioned in sliding sleeve main body by steady pin 7.
Described is rectangle, trapezoidal, pentagon, hexagon, octagon or ellipse for hanging the cross sectional shape of the non-circular fixed bar of sealing hook.
Basic principle of the present utility model is: original " annular enclosed " changed into dynamically by static state.That is to say, by a hook, " closed-loop is hook ", estimate the position that need to encounter barrier, the enclosed construction of original static state is transformed into the dynamic structure of " rolling cover " simultaneously that can " roll and step down " at any time also, allows " throwing over barrier automatically " and the state of " annular enclosed " that remains neglect neither.
The beneficial effects of the utility model:
The hook that the utility model can make to hang sealing hook, under the prerequisite that keeps self relative closure, can not come off, has the ability of automatically crossing asynthesis.The utility model can significantly promote the mobile flexibility of safety belt, makes operator guarantee inherently safe and take into account operating efficiency to become possibility.
The utility model can make the hook of " annular enclosed " state by means of an actual ability with automatic throwing over barrier of hook, and in " automatically crossing " and thereafter, also remains the state of " annular enclosed " and can not come off.After this hook entangles firm on cross bar, user can move freely and no longer be limited to connecting rod in cross bar length range.That is to say, no matter how long this root cross bar has, there are how many tie points centre, this hook can move freely and no longer needs midway manual transfer and remain " entangling firm " state in length range.Like this, operator just can, under the secure prerequisite of inherently safe, be used in topmost energy to promote work quality and efficiency aspect.
The utlity model has utmost point purposes widely, it almost goes for the place that any needs use of seat belts, particularly the top surrounding of the ship side of all naval vessels boats and ships, various high-lager buildings, petroleum chemical enterprise's larger hydrocarbon tank top fence etc. are located, this,, for guaranteeing operating personnel's safety and taking into account optimum working efficiency, will have everything to gain and nothing to lose.
The utility model can also be for space station.If (or supplementing afterwards) installs guide rail of the present utility model and hook in advance, space operation (certainly this may be on certain point of guide rail function of affix similar " pulling railway switches " so that free transfer trajectory) is carried out in any position that is conducive to the fastest, the safest arrival space station of astronaut, this advantage for being in weightlessness, be in extreme danger, should not be outside space capsule the astronaut of overlong time, may be significant.
The utility model only has and on one side has the ability of automatically crossing, and that is to say, it goes for barrier automatically the crossing of any direction of upper and lower, left and right, but must be single direction.If must be welded with the barrier of the second direction on same guide rail in the situation that some is special, also the countermeasure that has " having to take the second best ": local guide rail recovers circular, hook of the present utility model can be rotated on guide rail, to can aim at barrier implementation " semi-automatic " by manual mode, cross.
Guide rail of the present utility model and the free gap hanging between the hook of linking up with are unsuitable excessive.
Hook of the present utility model itself is more heavier, should not carry or install temporarily.Its correct using method is: land used of the present utility model hangs after the hook of linking up with is installed guide rail first no longer removes (user can be a plurality of according to prediction once mounting), is only the hook of carry-on common safety belt to be hung on hook of the present utility model at every turn.

Embodiment mono-.
As shown in Figure 1.
A kind of hook that can make sealing hook automatic turning obstacle-overpass, it comprises a sliding sleeve 1 with opening matching with the non-circular fixed bar that seals hook for hanging, in the upper end of sliding sleeve 1 openend, rotatable parts 2(being installed can be by fixed axis, bearing and runner form, fixed axis and sliding sleeve are fixedly linked, bearing holder (housing, cover) is contained on fixed axis and can moves by boss or snap ring restrictive axial), runner tight fit is arranged on or is fixedly mounted on bearing, during concrete enforcement, also can save bearing, the directly rotatable pavilion of runner is sleeved on fixed axis, and the restriction axially movable boss of runner or snap ring be set).On these rotatable parts 2, being provided with can be with its rotation spaced apart, be used for the swingle of opening Dynamic Closed 3, the interval angle of adjacent swingle 3 should guarantee have all the time swingle that the opening of sliding sleeve is sealed in rotation process, therefore, interval angle is generally below 45 degree, when moving to obstacle location place, sliding sleeve 1 must have a swingle 3 by obstacle, blocked and the opening on sliding sleeve is sealed, the first leaping over obstacles of another adjacent swingle, by the swingle 3 of obstacle gear along with turning the obstacle that is rotated away from that stops parts, the swingle of this bright leaping over obstacles turns to obstacle place and replaces last rotation root to seal sliding sleeve opening, so repeat, until sliding sleeve is pulled away from obstacle, on described sliding sleeve 1, be provided with the hooking structure 4 that mounts sealing hook.During concrete enforcement sliding sleeve 1 can be designed to " 7 " character form structure or " C " character form structure, in order to prevent that swingle is subject to the thrust consistent with rotatable parts turning cylinder or the effect of active force component in the closure of openings process to sliding sleeve, one insurance of the stop 5(with slot frame should be installed in the bottom of sliding sleeve 1 openend) during concrete enforcement, being arranged on swingle 3 arbitrary moment in rotation process on rotatable parts 2 has the lower end of at least in the slot of described stop, to prevent that swingle is subject to occuring bending and deformation or fractureing and make sliding sleeve depart from non-circular fixed bar with the active force impact in the same way of rotatable parts axle center, for hanging the cross sectional shape of the non-circular fixed bar of sealing hook, it is rectangle, trapezoidal, pentagon, hexagon, octagon or ellipse, only must be by transforming or the sleeve pipe that is welded makes it become non-circular structure if existing fixed bar is circular pin, and then upper hook of the present utility model.For the ease of sliding sleeve being sleeved on non-circular fixed bar, during concrete enforcement, can make one end hinge of the mounting rod 6 of sliding sleeve 1 open lower end mounting limit device 5 be contained in sliding sleeve main body, when money is installed, mounting rod 6 can be in linear state, thereby make sliding sleeve become " 7 " character form structure, installing formerly inserts swingle between immobilizing foundation and non-circular fixed bar, then rotating mounting rod to level makes sliding sleeve be " C " shape state, by steady pin 7 location, mounting rod is fixed in sliding sleeve main body again, prevents its rotation.
Embodiment bis-.
Can make the method that sealing hook can automatic turning obstacle-overpass, it comprises the following steps:
First, will originally hang the fixed bar design of sealing hook or be transformed into non-circular structure;
Secondly, the hook of embodiment mono-is set with on the fixed bar of aforementioned non-circular structure;
The 3rd, sealing hook is suspended on the hook described in embodiment mono-;
The 4th, movable hook hang device arrives one end perpendicular with fixed bar and is connected with fixed bar, the other end is when hanging the obstacle bar place that basis is connected, swingle and obstacle bar on hook offset, first the swingle that another root is adjacent strides across obstacle bar, further pull hook, thereby the swingle offseting with obstacle bar on hook forces the rotary part on hook to rotate drives other swingle stride across one by one obstacle bar and finally make hook leave obstacle bar, to realize without taking off sealing hook, can realize obstacle leap.
Details are as follows:
It should be noted that, the collar of original actual fixed bar using and hook mostly generally is circular, and " circle is to circle " makes above-mentioned " expectation need to be encountered the position of barrier " most probable move dislocation.Just there are two aspect problems in this: if we misplace to reduce by the mode of " increase counterweight, adjust center of gravity " on hook, can make complex structure, and on the steamer rocking effect also may not stablize, invalid especially on weightless space station; If we do not go to manage it, while needing, with hand, go to stir contraposition, result has just become " semi-automatic crossing ", advanced effect of the present utility model to have a greatly reduced quality.For fear of above-mentioned negative factor, as " high-speed railway need to change short rail into long rail ", the utility model also needs to gather together " rectangle fixed bar and the hook " that use " circular fixed bar and sealing hook " changes over higher standard, and the sealing hook that tradition is used can directly hang on the hooking structure 4 of hook.
As slide block 1 the most Hao Ping of hook main body 7 shaped edge mount structures that meet at right angles, on the cross bar of its upper opening portion, process fixed axis, the straight flange lower end relative with opening is provided with two holes, one for installing hinge, another is welded with the becket of hook sealing hook for alignment pin 7 is installed on straight flange.
Swingle is installed on runner can be by uniform totally eight swingles 3 of 45 degree, and shape is as helicopter rotor, and its runner can directly be enclosed within on fixed axis or by bearing holder (housing, cover) and rotate freely on fixed axis.
The lower frame of slide block 1 is connected with rectangle stop (insurance frame), can hold swingle and pass through betwixt.
The utility model is in use: non-circular fixed bar is enclosed in the centre of hook, and swingle 7 can rotate or not rotate on fixed axis, can in the slotted eye of stop, slip over or stop after proceeding to bottom.
The course of work of the present utility model is:
Operator directly hangs over common seat belt hanger on one's body on the hooking structure 4 of hook, if less, the of the present utility model hook of operator's moving range is at non-circular fixed bar (guide rail), upper sliding scale is less while not encountering barrier, and swingle 3 will not had an effect; When people's moving range is larger, the swingle 3 on the utility model hook will touch the barrier vertical with fixed bar (vertical rod), and barrier can not be touched in other position.When now, swingle 3 will start passive rotation, from barrier, twist over.Any swingle, to any direction turn-off, must just have the close other swingle cover of coming, the absolutely not neutral gear that occurs of inner side edge of rectangle fixed bar simultaneously.That is to say, rectangle fixed bar at any time, all will be by " Dynamic Closed " in hook.Change angle and also can say, only otherwise people for disassembling, this hook can not automatic slippage.
Suppose this moment to occur unexpected sliding Falling, suppose that swingle 3 this moment can be subject to strong impact and have the possibility of outside distortion, stop 5 will be brought into play safety effect immediately this moment, because have at least at any time three to be the inner side that is wrapped in non-round fixed bar downwards by eight uniform swingles 3 of 45 degree, and wherein have at least one to be to be in the notch of stop 5, this root is slightly out of shape limited device 5 immediately and blocks, and does not infinitely outwards have the possibility of being out of shape, making " Dynamic Closed " collapse.
Above introduced be the structure of " obstacle on non-round fixed bar (guide rail) is at inboard face ", this should be structure and the mode of the most easily reequiping use.If the barrier that guide rail need to be welded on ceiling, need to cross is automatically upper, the utility model is effective equally.Slightly different with above-mentioned " profile form ", swingle is born the slip responsibility on guide rail of being everlasting day, protecting against shock insurance responsibility that stop 5 is born by bigger by needs.
If need to by guide rail weldering above deck, the barrier that need to automatically cross under, situation and barrier are upper similar and simpler, so no longer concrete analysis introduction.
The utility model does not relate to partly all prior aries that maybe can adopt same as the prior art to be realized.
