Description
Technical field
The utility model is related to a kind of falling mound formula throttle locking device.
Background technology
Falling mound formula throttle locking device is, in locking rope middle setting falling mound, when any one air door stress is opened, to close
Lock rope is in tight state, so as to realize the locking of other one air door；When external force is removed, the gravity reality that air door passes through falling mound
It is now automatic to close.The falling mound formula automatic closure effect of throttle locking device door leaf is good, by influenced by wind pressure, installation cost be low, maintenance
It is convenient, it is widely used in underground, but such blocking device there is also some defects in down-hole application：One is in tunnel
Two when helping to be required to install blocking device, and the riding position of falling mound is vulnerable to the influence of geomantic omen pipeline.Because geomantic omen pipeline is installed
Position is relatively low, and the lifting position of falling mound can only be confined to the lower section of geomantic omen pipeline, due to being limited by lifting space, it is impossible to completely
Play the effect of falling mound.Even occur tangling geomantic omen pipeline because of falling mound support and caused by the phenomenon that can not fully open of air door；Two are
Falling mound is run up and down along lane side, and friction is produced to lane side, not only increases the resistance for opening air door, and cause the wall skin of lane side
Because friction comes off, the neat and artistic property of lane side is influenceed.
The content of the invention
For the problem that above-mentioned prior art is present, the utility model provides a kind of falling mound formula throttle locking device, the dress
Put and do not limited by narrow space not only, can guarantee that air door fully open with it is effectively closed, its falling mound is in upper and lower running
In will not to lane side produce friction, so as to the resistance of door opening will not be increased, the wall skin of lane side is come off.
To achieve these goals, the utility model provides a kind of falling mound formula throttle locking device, including falling mound, closes rope rope
And protector, rectangular frame one of the protector by superposed level, the horizontal rectangular framework two positioned at bottom and company
The many vertical beams composition between rectangular frame one and rectangular frame two is connect, the space in the middle part of the protector forms the falling mound
Running space, the left part between the top front-axle beam of rectangular frame one and the back rest is fixedly connected holding for two levels parallelly with right part
Carrier beam, is provided with a fixed pulley in the middle part of each carrier bar, one is hung with two spaces of fixed pulley bottom and is moved
Pulley, the bottom of the rectangular frame two is at least fixedly connected with the fixed beam for extending laterally in its front and rear both sides, described
Fixed beam being fixedly connected with the ground on the outside of air feed supply channel through the through hole on its top by ground bolt；It is described to close rope rope
Middle part successively winding cross left side the race of fixed pulley, the race of movable pulley and right side fixed pulley race, close rope rope
Left end is connected with the free end of air door, and the other end for closing rope rope is connected with the fixing device on the right side of the protector,
The middle part for closing rope rope is connected with the upper end of the falling mound in the running space.
The setting that the utility model passes through protector, can be such that falling mound is not connect with lane side friction during up and down motion
Touch, the resistance of door opening can not only be reduced, be also avoided that and the metope of lane side is ground away, movable pulley drives falling mound to move up and down can
To play a part of to reduce frictional resistance；Simultaneously as protector is fixed on the ground on the outside of air feed supply channel by fixed beam
Face is fixedly connected, and so, falling mound space can be moved on into air feed supply channel outside, can avoid empty for interior supply channel
Between narrow and small limitation, so as to can guarantee that air door fully open with it is effectively closed.
Further, safeguard for convenience, described closing is connected with hook in the middle part of rope rope, the falling mound is by hook and closes rope
Rope connection.
Further, in order to ensure load bearing stength, the vertical beam, rectangular frame one and rectangular frame two are using the angle of 40mm
Iron is made.
As one kind preferably, the protector outer surface is coated with galvanized iron sheet.
Further, in order to preferably ensure to close the motion of rope rope energy predetermined paths, the left end for closing rope rope sets through fixation
The leading block put on lane side is connected with the free end of air door.
