Abstract
The utility model relates to an anti-falling climb assister for a vertical ladder, which comprises an upper pulley block, a lower pulley block, a steel wire rope for connecting the upper and the lower pulley blocks, and the like. A lock is mounted on the steel wire rope and used for being connected with a protective device worn by a climber, and a motor is connected to a spindle of the lower pulley block to be linked with the same. The anti-falling climb assister is safe first, serves the purposes of comfortableness and labor saving, is controlled electromechanically to achieve high assisting power for climbing up, labor saving and comfortableness for climbing down, and is added with a safety anti-falling function, and thereby safety factor is improved. Great impact to falling staff is avoided by the aid of the motor slowing the descent. The anti-falling climb assister in the module assembled structure is easy to assemble and disassemble and convenient to maintain.
Description
Technical field
The utility model relates to the anti-drop device on a kind of cat ladder of ascending a height, and is specifically related to the anti-fall climb-aiding device that a kind of work high above the ground that is used for fields such as wind-driven generator, communication is used, and belongs to International Classification of Patents E06C technical field.
Background technology
The regular maintenance of wind-driven generator in the prior art generally needs to come upper and lower tower tube by means of climb-aiding device.And present climb-aiding device, security reliability is relatively poor, does not have safe anti-drop function, time and effort consuming in the process of upper and lower cat ladder, and that falls is very risky.Simultaneously, inconvenience is installed, the fault rate height.
Summary of the invention
The purpose of this utility model is to provide a kind of safety factor height, the anti-fall climb-aiding device of comfortable labour-saving cat ladder.
The purpose of this utility model is achieved through the following technical solutions.
The anti-fall climb-aiding device of a kind of cat ladder comprises top sheave group, downslide wheels and the parts such as wire rope that connect upper and lower assembly pulley, snap close is housed, to be connected with protective device that climbing person wears on the wire rope; Motor is connected on the main shaft of downslide wheels, to link with the downslide wheels.
Circuit for controlling motor comprises compositions such as resistance, Zener diode, armature and one-way SCR.Armature is in parallel with controllable silicon, and an end of resistance is connected with its parallel connected end, and the other end of resistance is connected with the positive pole of Zener diode; The negative pole of Zener diode is connected with silicon controlled is anodal.
The utility model is with safety first, comfortable laborsaving be purpose, adopted the control of electromechanical integration.It is big, laborsaving during descending stair, comfortable to have reached last when ladder power-assisted, and has increased safe anti-drop function, has improved safety factor.Stop by the slow of motor, the personnel that guarantee to fall are not subjected to big impact force.Adopted the module package assembly, easily adorned readily removable, easy to maintenance.
Description of drawings
Fig. 1 is a mechanical part structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model circuit part.
Among the figure: 1. top sheave group, 2. downslide wheels, 3. motor, 4. wire rope, 5. armature, 6. resistance, 7. Zener diode, 8. controllable silicon.
The specific embodiment
Referring to Fig. 1, cat ladder comprises top sheave group 1, downslide wheels 2 with anti-fall climb-aiding device, wire rope 4 is housed to connect upper and lower assembly pulley, on the wire rope 4 snap close is housed, and is connected with climbing person's health by snap close.Motor 3 is connected on the main shaft of downslide wheels 2 to link with the downslide wheels.
Referring to Fig. 2, circuit for controlling motor is made of resistance 6, Zener diode 7, armature 5 and one-way SCR 8; Armature 5 is in parallel with controllable silicon 8, and an end of its parallel connection is connected with an end of resistance 6, and the other end of resistance 6 is connected with the positive pole of Zener diode 7; The negative pole of Zener diode 7 is connected with the positive pole of controllable silicon 8.
In use, climbing person is the upper and lower power-assisted that climbing person is provided by motor during operate as normal with rope snap close and wire rope 4 lockings that are contained on top sheave group 1 and the downslide wheels 2, makes the climbing process laborsaving comfortable.When climbing person accidentally drops or slips and when falling, climbing person falls, drive wire rope 4 to glide with fast speed, the speed reversal of downslide wheels 2 is accelerated, motor 3 counter-rotatings.Armature 5 produces high voltage, and voltage triggers controllable silicon 8 conductings by resistance 6 and Zener diode 7, causes motor 3 to produce braking moment; start safe anti-drop function, the armature that makes motor 3 produces the counter-force distance near short circuit; stop climbing person's downslide, realized anti-falling protection.When climbing person caught cat ladder once more, the output voltage of motor 3 was zero, and controllable silicon 8 recovers to carry and ends state, and anti-drop function resets, and waits for the startup of overrunning again.
