Description
Technical field
The present invention relates to safety device fields of ascending a height, in particular to iron tower climbing protective device and equipment.
Background technology
Iron tower of power transmission line is the important component of current electric system major network, and inspection personnel are transported during the fortune inspection of steel tower
It is huge that tower workload need to be carried out stepping on, but be based on many reasons, the protection problem for stepping on tower process top and the bottom never obtains root
Solution in sheet, otherwise method used at present is cumbersome unrealistic or amount of investment is huge to being difficult to receive.Cause staff
Dynamic then violate security regulations, there is serious security risks for the course of work.
Electric power line tower structure design once considered safety protection problem, but some is because reasons in structure (enclose by protection
Column), for some because of field conduct, the problem of being finally all eliminated, bringing is that working at height personnel lose completely in climbing
Deprotection.The high-altitude personnel thereby resulted in death by accident of falling also has generation.
And electric power line tower structure is complicated, is divided into main material, oblique material, interconnecting piece and grades, the protection button of exploitation needs to adapt to
It a variety of rapid connection methods (as original is directly on waist rope wrapped buckle) while realizing and quickly artificially unlocks alternating.
Existing common iron tower climbing protective device has following several：
Presently most used double waist rope safety belts are used alternatingly pole and expend bodily strength, and staff often steps on 1 meter or so and just needs to do
Go out button rope, around the operation of material, solution rope, normal 40 meters of steel tower can deplete the muscle power of general staff.So the operating method
And product can not almost be promoted.
Rail mounted anti-falling protection, the protection is easy to use, and energy consumption is relatively low, but surpasses hundred yuan, each 40 meters per meter-gage road cost
Steel tower just needs 5000 yuan or so of cost, of high cost, can not large area use, this resulted in major part 98% steel tower exist
It is currently unprotect row rail.
Protect the exploitation of row rail simple, market confusion, the row rail different modes of different manufacturers different model, cause safety belt without
Method is general.

Add active force that it is made to be moved up relative to steel tower 401.
Referring to Fig. 3, when receiving downward pulling force at button hole 301, monoblock snap-gauge 100 is tilted relative to steel tower 401, card
Non-slip material 201 inside plate 100 can rub with steel tower 401 and keep snap-gauge 100 opposing stationary in steel tower 401.In fortune inspection personnel
It does not stand firm, when something unexpected happened, snap-gauge 100 receives downward pulling force, can at once lock onto on steel tower 401, is examined for fortune
Personnel provide safeguard protection.
Referring to Fig. 4, when monoblock snap-gauge 100 receives the effect of upward power, monoblock snap-gauge 100 is relative to steel tower 401
Vertically, the Non-slip material 201 inside snap-gauge 100 can be detached from steel tower 401 surface or due to the effect of not no cross force make with
Its frictional force substantially reduces, and snap-gauge 100 can be enable to be lifted up, slowly raised position.
The rigid plastics that snap-gauge 100 selects material lighter is transporting inspection personnel by steel tower on iron tower climbing protective device band
401, the plastics snap-gauge 100 of main body of the snap-gauge 100 as iron tower climbing protective device, lighter weight can mitigate fortune inspection personnel's
Burden makes fortune examine personnel when stepping on tower using iron tower climbing protective device, can more easily climb up eminence, saves muscle power.
Fig. 5 and Fig. 6 is please referred to, in embodiments of the present invention, Non-slip material 201 is hinged with snap-gauge 100, and gripping orientation and pine
Relaxation state is switched by the Restricted Activities of snap-gauge 100, and each section of snap-gauge 100 is both provided with two Non-slip materials 201, is increased
With the friction on 401 surface of steel tower, when snap-gauge 100 is by downward pulling force, Non-slip material 201 is in gripping orientation, and snap-gauge 100 does not have
Movable space, when snap-gauge 100 is by upward pulling force, Non-slip material 201 is in relaxed state, and snap-gauge 100 can be relative to iron
Tower 401 moves up.The rubber block that Non-slip material 201 selects friction coefficient larger.
Referring to Fig. 5, the snap-gauge 100 for being connected in steel tower 401 is in clamping by Non-slip material 201 is rotated to first direction
State, first direction are to rotate up, and make rotation angle at 30 ° hereinafter, when snap-gauge 100 is by downward by fixture block 204
Pulling force, snap-gauge 100 are rotated up relative to 401 slide downward of steel tower, Non-slip material 201 relative to steel tower 401, clamping steel tower 401
Reach the state opposing stationary with steel tower 401.
Referring to Fig. 6, the snap-gauge 100 for being connected in steel tower 401 is in relaxation by Non-slip material 201 is rotated to second direction
State, second direction are to be rotated down, and make rotation angle at 60 ° hereinafter, when snap-gauge 100 is by upward by fixture block 204
Pulling force, snap-gauge 100 are rotated down relative to 401 upward sliding of steel tower, Non-slip material 201 relative to steel tower 401, can no longer with iron
401 surface of tower contacts, and iron tower climbing protective device is enable to be moved up relative to steel tower 401.
In other embodiments of the invention, referring to Fig. 7, Non-slip material 201 is to be wrapped in first part 101, second
Points 102 and Part III 103 in three Anti-slip covers, Anti-slip cover includes sawtooth set 202 and friction sleeve 203, wherein being wrapped in the
A part 101 is sawtooth set 202, and it is friction sleeve 203 to be wrapped in second part 102 and Part III 103.
Fig. 8 and Fig. 9 is please referred to, sawtooth set 202 includes two sawtooth framves, and sawtooth covers 202 for multiple sawtooth, and all sawtooth
Direction having the same, all tilts down, and when being suitable for snap-gauge 100 by downward active force, sawtooth can block steel tower
401, keep iron tower climbing protective device static relative to steel tower 401.
The embodiment of the present invention also provides a kind of iron tower climbing protection equipment comprising safety belt and above-mentioned iron tower climbing are protected
One end of protection unit, safety belt is connected to button hole 301, and the other end is connect with human body, ensures that fortune inspection personnel safety is ascended a height.
In conclusion iron tower climbing protective device provided in an embodiment of the present invention, by constantly switch relaxed state and
It is climbed upwards relative to steel tower 401 when gripping orientation realizes the operating point with replacement static relative to steel tower 401 when work, clamping shape
State and relaxed state are all easier to realize, so that fortune inspection personnel is easily ascended a height and is stopped and transport inspection, save muscle power, be steel tower 401
Fortune of ascending a height inspection personnel provide safeguard protection, while simple in structure, cheap, can produce in batches, and suitable for difference
The steel tower 401 of structure from different places.
The iron tower climbing that the present invention provides embodiment protects equipment, as a result simply, cheap, is suitable for different regions not
Isostructural steel tower 401, for steel tower 401 ascend a height fortune inspection personnel provide safeguard protection, enable steel tower 401 ascend a height fortune inspection personnel
401 equipment of maintenance steel tower of safety and stability.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
