611 and second bearing rod 612 can block 61 is whole to play undertaking effect to pressing, prevent from pressing that block 61 is whole to directly act on pressure
Force snesor 62 provides protection to pressure sensor 62.
To promote the protective effect for pressure sensor 62, first holding groove 13 and the second holding groove 14 of the present embodiment
Inside it is located in the profile of the first bearing rod 611 and the second bearing rod 612 and is respectively arranged with the buffering being arranged along the vertical direction
Spring 80.Based on the above structure, when pressing the pushing of block 61, when the first bearing rod 611 and the second bearing rod 612 push, buffering elastic
Spring 80 has a upward active force to the first bearing rod 611 and the second bearing rod 612, presses block 61 downwards to counteract
A part of impact force, and then prevent from pressing block 61 and biggish impact force generated to pressure sensor 62 and destroys its and specific ties
Structure.
Further to promote the stability for pressing block 61, as a preferred embodiment, first holding groove 13 of the present embodiment
Two are set as with the second holding groove 14 and is distributed along the front and back, and the first bearing rod 611 and the second bearing rod 612 are disposed as
It two and is distributed along the front and back.
To accelerate to press the process that presses of block 61, reduction is pressed the time, and the transmission device 60 of the present embodiment further includes accelerating
Spring 63, acceleration spring 63, which is arranged in, to be pressed between block 61 and the top inner wall of cage 10, and the lower end of acceleration spring 63 is set in
Pressing on block 61 and upper end and abutting with the top inner wall of cage 10 (for the function and effect for promoting acceleration spring 63, can will accelerate
Spring 63 is set as four and is distributed in the corner location for pressing block 61 respectively).Based on the above structure, by pressing 61 He of block
Acceleration spring 63 is set between the top inner wall of cage 10, and traction rope 40 is in the lifting process of traction cage 10, due to traction
What rope 40 provided is always pulling force, and therefore, acceleration spring 63 is in compressive state always, after traction rope 40 disconnects, acceleration spring
63 pairs press block 61 and apply downward active force, while under the gravity for pressing block 61 itself, pressing relative to only relying on
The gravity of block 61 itself, can enable to press block 61 and press pressure sensor 62 within the shorter time and trigger fall prevention rope
Cage 10 is tensed, can more have timely completed and press and anti-fall process.
The anti-fall mechanisms such as block 61, pressure sensor 62 are pressed to prevent staff from touching, one kind of the present embodiment is slow
Rushing anti-falling cage 10 further includes isolation board 15, isolation board 15 be arranged in cage 10 cage 10 is divided into be distributed up and down it is anti-fall
Chamber and transport chamber, the lower end of traction rope 40 are distributed in anti-fall intracavitary after the upper wall of cage 10, and pull rod 20 passes through in left-right direction
Wear anti-fall chamber and both ends be distributed in the outside of cage 10, press block 61, pressure sensor 62 be arranged at it is anti-fall intracavitary.Based on
Cage 10 is divided into anti-fall chamber and transport chamber using isolation board 15 by upper structure, can be to avoid pressing block 61, pressure sensor 62
The anti-fall mechanism of lamp touches staff in transmission process causes staff injured.
The above is only the preferred embodiment of the present invention, and therefore it does not limit the scope of the patent of the utility model,
Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported
Used in other related technical areas, it is also included in the patent protection scope of the utility model.
