Abstract
The invention discloses a pneumatic speed limiter. The pneumatic speed limiter comprises a balloon, an air duct, ventilation plates and switches. There are two ventilation plates and two switches. The two ventilation plates are installed on two ends of the air duct respectively. The two switches are installed on the two ventilation plates respectively. Two ends of the balloon are connected to the two switches respectively and are located in the air duct. When a mechanism moves up and down, an air flow is generated. In the invention, through the ventilation plates, the air flow is introduced into the air duct so that the balloon in the air duct can move because of the air flow. When the mechanism is in a stall state and other conditions, the air flow is increased and movement of the balloon is increased too so as to trigger a switch to prompt a user to carry out speed limit timely. The structure of the speed limiter is simple and work reliability is high.
Description
Technical field

On plate, balloon two ends are connected with two switches respectively, and are located in airduct.
The invention has the beneficial effects as follows: air-flow will necessarily be produced due to when mechanism moves up and down, the present invention utilizes ventilating board
Air-flow is introduced so that the balloon in airduct can move because of air-flow in airduct, when there is stall in mechanism, air-flow
Will necessarily increase, can be increased by the activity of this balloon, thus trigger switch is to remind the timely speed limit of user.The structure letter of the present invention
Single, and functional reliability is strong.
In some embodiments, present invention additionally comprises installing plate, installing plate is connected with airduct.The setting energy side of installing plate
Just the installation of the present invention.
In some embodiments, two switches all include fixed seat, sliding seat, spring and travel switch, wherein spring
One end is connected with fixed seat, and the other end is connected with sliding seat, and sliding seat is movably arranged in fixed seat, and travel switch is arranged on solid
In reservation, and it is located under sliding seat.Sliding seat can coordinate the motion of balloon to move, and travel switch can be used as prompting subscriber computer
The structure of structure stall, and the resetting and limit the movement of sliding seat of spring energy portable propelling seat, fixed seat then can Convenient switch
Install, as a result, switch can coordinate the work of balloon to remind user to carry out speed limit in good time, functional reliability is strong.
In some embodiments, including connecting rope, balloon two ends are connected with two sliding seat by connecting rope respectively.Even
The setting of splicing can guarantee that the connection reliability of balloon and sliding seat.
In some embodiments, two switches all include collar, and collar is arranged in fixed seat, and are located at sliding seat
On.The setting of collar can prevent the mobile range of sliding seat too big, causes the damage of sliding seat, ensures the work of sliding seat with this
Reliability.
In some embodiments, it is filled with noble gases in balloon.Noble gases be filled with the safety that can increase balloon
With buoyancy so that balloon can preferably work.
In some embodiments, two ventilating boards are equipped with hole, and hole is connected with airduct.The setting in hole can facilitate air-flow
Enter, to ensure balloon energy accurate work.
In some embodiments, the horizontal width at airduct two ends is greater than the horizontal width at middle part.Thus, air-flow can be more
It is aggregated in well middle part so that the stress of balloon is bigger, the functional reliability of balloon is ensured with this.
Brief description
Fig. 1 is the structural representation of the pneumatic limiter of speed of one embodiment of the present invention.
Fig. 2 is the structural representation of the switch of pneumatic limiter of speed of Fig. 1.
Specific embodiment
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
With reference to Fig. 1 and Fig. 2, pneumatic limiter of speed, including balloon 1, airduct 2, ventilating board 3, switch 4, installing plate 5 and connecting rope
7.
Airduct 2 the inside hollow, and the horizontal width at airduct 2 two ends is greater than the horizontal width at middle part so that airduct 2 is
The cylinder of middle part indent.Ventilating board 3 is two, and two ventilating boards 3 are arranged on airduct 2 two ends by bolt respectively, and two lead to
Hole 31 is equipped with aerofoil 3, hole 31 is connected with the inside of airduct 2.In addition, installing plate 5 passes through to be welded to connect on airduct 2, and
Installing plate 5 is provided with reinforcement.
Switch 4 is also two, and two switches 4 all include fixed seat 41, sliding seat 42, spring 43, travel switch 44 and card
Circle 45.The fixed seats 41 of two switches 4 are arranged on two ventilating boards 3 by bolt respectively, spring 43 one end and fixed seat 41
It is fixedly connected, the other end is fixedly connected with sliding seat 42, in fixed seat 41, is provided with groove, sliding seat 42 is movably arranged on fixed seat 41
Groove in so that sliding seat 42 can carry out certain up and down in fixed seat 41, travel switch 44 is arranged on fixed seat 41
On, and be located at below sliding seat 42, collar 45 is also mounted in fixed seat 41, and is located in sliding seat 42, prevents from living with this
Dynamic seat 42 departs from fixed seat 41.
It is filled with noble gases, noble gases can be helium, connecting rope 7 respectively with two is passed through at the two ends of balloon 1 in balloon 1
The sliding seat 42 of individual switch 4 is connected, in addition, balloon 1 is located at the center of the inside of airduct 2.
During present invention work, installing plate 5 is arranged in the mechanism needing to move up and down by bolt, as elevator
Car, workbench of crane etc., and travel switch 44 is electrically connected with overspeed prompting device.
When mechanism's up/down is mobile, mechanism can drive the present invention, and up/down moves together, produces in up/down moving process
Air-flow can pass through airduct 2 upper below the hole 31 of ventilating board 3 enter in airduct 2, and after balloon 1, from airduct 2
Lower above the hole 31 of ventilating board 3 flow out, and up/down side enters airflow function on balloon 1, balloon 1 can be promoted to carry out under/
Upper movement, but the balloon 1 of up/down movement can drive positioned at Xia above switch 4 sliding seat 42 mobile, and make to inductive switch 4
Spring 43 compressed.
When the speed of mechanism is in rated range, because the size of air-flow is limited, the movement of balloon 1 is limited, spring
Within the specific limits so that sliding seat 42 displacement is also limited, sliding seat 42 will not touch travel switch 44 for 43 compression.
And when the speed of mechanism overruns, air-flow can accordingly increase, the mobile range of balloon 1 increases, and switchs 4
Spring 43 be further compressed, the displacement of sliding seat 42 increases and touches travel switch 44, then 44, travel switch
The number of delivering letters arrives at overspeed prompting device, reminds user facility stall with this.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, not
On the premise of departing from the invention design, some deformation can also be made and improve, these broadly fall into the protection model of the present invention
Enclose.
