To more preferable guiding role, the lower end of the reset lever 41 is equipped with handle, facilitates staff to pull reset lever 41.
The utility model anti-falling safety device, wherein the top 26 includes two vertical plates, the lower end of two vertical plates leads to
Cross a transverse plate to be connected, lower face of two vertical plates respectively with two gripping blocks 25 offsets, and the lower face of the transverse plate is consolidated
The even mandril 27.During original state, i.e., when gripping block 25 is moved upwards not along wedge track 44, second spring 29 is in pressure
Contracting state, one end of bumping post 32 are stretched out outside baffle 30 and positioned at the top of 26 transverse plates of top, prevent the upward movement in top 26.When
After bumping post 32 is pulled back in baffle 30, bumping post 32 no longer stops the transverse plate of top 26, and then coming directly towards 26 at this time can be the
The lower movement upwards of elastic force effect of two springs 29, so as to promote gripping block 25 to be moved upwards along wedge track 44.
The course of work of the utility model is described below：
Since the structure ＆ working mechanism of four safe locking components is identical, only with wherein any one safety
Locking member illustrates.When the tenesmus suddenly of carriage 2 reaches certain speed, haulage cable 45 drives the first rope sheave 5
Rotated with the second rope sheave 6, it is in order to improve the reliability of the utility model in use, so i.e. to set the second rope sheave 6
One in two haulage cables 45 is set to break, remaining one remains able to drive 6 turns of the first rope sheave 5 and the second rope sheave
It is dynamic, since the first rope sheave 5 can drive the first sheave shaft 7 to rotate together, the speed limited wheel 11 being fixed on the first sheave shaft 7
Also and then rotate together, two be installed on speed limited wheel 11 rejection tablet is thrown away at the same time, at this time, is articulated with rejection tablet withdraws end second
Connecting rod 18 promotes eccentric wheel 17 to rotate, and way roller 16 is close at the same time and pushes against roller 16 for the big end of two eccentric wheels 17, makes roller
16 can followed by speed limited wheel 11 rotates together, and the third connecting rod 19 being so hinged on roller 16 will move, and the 3rd
Connecting rod 19 drives the binding post plate 20 that is fixed thereon to move, due to being connected with brake cable 35 on binding post 21, then 35 quilt of brake cable
Tense, the other end of brake cable 35 pulls bumping post 32 from lateral 31 side of T-shaped frame of baffle 30 1, and bumping post 32 no longer stops top at this time
First 26, top 26 is moved upwards under the action of second spring 29, is then come directly towards 26 and is headed on gripping block 25 along wedge track 44
Movement upwards, when two gripping blocks 25 move to the upper end of wedge track 44, two gripping blocks 25 press from both sides guide steel wire rope 1
Tightly, whole carriage 2 has been fixed on guide steel wire rope 1 at this time, so as to prevent carriage 2 from falling suddenly.It is upward in top 26
While movement, it can trigger limit switch 38, and limit switch 38 controls the power set of carriage 2 to shut down, prevents it
Continue traction carriage 2 to move up and down and drag guide steel wire rope 1 disconnected.
It is as follows to release locking state process：Reset lever 41, reset lever are pulled downward on by the handle of reset lever 41
41 drive mandrils 27 move down, and top 26, which also moves downward, re-compresses second spring 29, the gripping block to offset with top 26
25 move downward also along wedge track 44, and gripping block 25 unclamps guide steel wire rope 1 at this time, then rotate speed limited wheel 11, make the
Three-link 19 no longer tenses brake cable 35, and at this time, under the pulling force effect of the first spring 15, rejection tablet is recovered in speed limited wheel 11.When
When top 26 moves downward origin-location, it departs from limit switch 38, and limit switch 38 no longer controls the power of carriage 2 to fill at this time
Put, since brake cable 35 loosens, then under the elastic force effect of the 3rd spring 33, bumping post 32 is from the lateral baffle 30 1 of T-shaped frame 31 1
Baffle 30 is stretched out in lateral movement, the termination of bumping post 32 again, and the transverse plate of top 26 is located at the lower section of bumping post 32 at this time, unclamps and resets
The handle of pull rod 41, under the action of 42 elastic force of resetting spring, reset lever 41 drives mandril 27 to move upwards, until top 26
Transverse plate offset with bumping post 32, bumping post 32 prevents top from 26 continuing up at this time, while also it is prevented that gripping block 25
Continue up, gripping block 25 cannot also lock guide steel wire rope 1, and whole anti-falling safety device is in the unlocked state.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to this practicality
New scope is defined, and on the premise of the spirit of the design of the utility model is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical solution of utility model is made, should all fall into the protection that the utility model claims book determines
