Description
Technical field
The utility model relates to a kind of centrifugal safety lock power-off protection apparatus, specifically plays the power-off protection effect in work high above the ground, belongs to the aerial lift device technical field.
Background technology
The skin of building operations or highrise building is safeguarded, is all needed to use high-lift operation hanging cradle.In the last few years, along with the extensive use of high-lift operation hanging cradle on market, safety lock was as requisite safety device in the hanging basket, and its style constantly updates, and function is constantly strengthened.
According to different building types, the style of hanging basket presents varied, and is funnel-shaped etc. such as: rectangle, circle, deep-wall type, superelevation, in line with the idea that people-oriented, more and more higher to the brake request of safety device.Original brake safe rope can only play the effect of automatic locking rope, and safety can't be satisfied the demand; Complex structure is unreasonable simultaneously.Traditional high-lift operation hanging cradle can not adapt to the security performance needs of the various hanging baskets of high speed development with safety device.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of centrifugal safety lock power-off protection apparatus is provided, and utilizes the centrifugal-block assembly when safety rope exceeds the speed limit elevator to be cut off the power supply, and has protected constructor's normal construction.
The technical scheme that provides according to the utility model, a kind of centrifugal safety lock power-off protection apparatus mainly comprises a little tactile switch, centrifugal-block assembly, touch panel, hand-reset bar and power supply indicator, described centrifugal-block assembly comprises a plurality of centrifugal-blocks, the rounded array of a plurality of centrifugal-blocks branch, each center, centrifugal-block rear portion is fixed by bearing pin, the anterior linking springs front end of described centrifugal-block; The rear end of described spring is fixedly mounted on the circle centre position of centrifugal-block distribution circle.
Described centrifugal-block assembly below is provided with touch panel, touch panel center mounting center axle; Described touch panel top is touched switch with point and is connected, and described point touches the switch end and is provided with spring leaf, and touch panel top is touched switch by spring leaf with point and fitted tightly.
Described point touches the switch right side and is provided with elevator, connects electric power connection line on the elevator, and electric power connection line connects power supply; The other power supply indicator that also is provided with of described elevator, when the power on circuitry of elevator, power supply indicator lights, and when the elevator down circuitry, power supply indicator then extinguishes.
The place ahead of described touch panel bottom is provided with the hand-reset bar, adjusts the position of the place ahead touch panel by the hand-reset bar.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; The constructor has been formed protective effect by centrifugal-block component limitations safety rope rising or falling speed in the reasonable scope.

The specific embodiment
Following the utility model is further described in connection with the embodiment in the accompanying drawing:
Such as Fig. 1 ~ shown in Figure 3, the utility model mainly comprises a little tactile switch 3, centrifugal-block assembly, touch panel 4, hand-reset bar 6 and power supply indicator 8, described centrifugal-block assembly comprises a plurality of centrifugal-blocks 1, the rounded array of a plurality of centrifugal-block 1 branch, and each center, centrifugal-block 1 rear portion is fixed by bearing pin; Anterior linking springs 2 front ends of described centrifugal-block 1; The rear end of described spring 2 is fixedly mounted on the circle centre position of centrifugal-block 1 distribution circle.
The centrifugal-block assembly of implementation column is provided with six centrifugal-blocks 1 as shown in Figure 3, connects a spring 2 on each centrifugal-block 1.
Described centrifugal-block 1 assembly below is provided with touch panel 4, touch panel 4 center mounting center axles 5; Described touch panel 4 tops are touched switch 3 with point and are connected, and described point touches switch 3 ends and is provided with spring leaf 10, and touch panel 4 tops are touched switch 3 by spring leaf 10 with point and fitted tightly.
Described point touches switch 3 right sides and is provided with elevator 9, connects electric power connection line 7 on the elevator 9, and described electric power connection line 7 connects power supply 11; The described elevator 9 other power supply indicators 8 that also are provided with, when the power on circuitry of elevator 9, power supply indicator 8 lights, and when elevator 9 down circuitry, 8 of power supply indicators extinguish.
The place ahead of described touch panel 4 bottoms is provided with hand-reset bar 6, adjusts the position of the place ahead touch panel 4 by hand-reset bar 6.
Operating principle of the present utility model is: when the normal operation beginning, touch panel 4 fits tightly by spring leaf 10 with the tactile switch 3 of point is in the same place.Described touch panel 4 and point touch switch 3, elevator 9, power supply 11, electric power connection line 7, power supply indicator 8 formation power-on circuits, when the speed of hanging basket safety rope lifting is designing within the set-point scope, and centrifugal-block assembly normal rotation, whole circuit normal operation.
In use, the hanging basket safety rope drops at a high speed because meet accident, and the rotating speed of centrifugal-block assembly surpasses the design set-point, and the centrifugal force of centrifugal-block 1 is greater than the pulling force of spring 2, and centrifugal-block 1 front portion overcomes the pulling force of spring 2 and outwards flicks.The touch panel 4 tops disengaging in centrifugal-block 1 anterior drive the place ahead that outwards flicks and contacting of spring leaf 10, this moment, circuit disconnected, and elevator 9 shuts down, and power supply indicator 8 extinguishes, and safety rope is by locked.
When needs reclose circuit, promote hand-reset bar 6, hand-reset bar 6 promotes again touch panel 4 bottoms, so that the top of touch panel 4 breaks away from the control of centrifugal-block 1, centrifugal-block 1 is retracted original position by spring 2, and touch panel 4 returns to the state with spring leaf 10 close contacts, and whole circuit is path again.
