Description
Technical field
The invention belongs to ladder climbing equipment technical fields, are related to a kind of universal steelframe ladder climbing device.
Background technique
Ladder is the common ancillary equipment of power industry, is chiefly used in the place that fixed equipment needs to ascend a height, such as substation
Main transformer, substation's H-frame pole framework, electric power line pole tower, building etc..
In above equipment, when needing repair and maintenance, each professional teams and groups such as operation, maintenance, test all can to equipment into
The test of row profession and maintenance can above be arrived at the top of equipment and be worked by ladder in maintenance process.
Q/CSG510001-2015 " China Nanfang Grid Co., Ltd's electric power safety working regulation " 20.2.3 rule
It is fixed, work on not having parapeted scaffold, highly more than 1.5m when, should use of seat belts, or take other reliable safely
Measure.20.2.2 provides that safety belt should should not be to hang over mobile, sharp or unstable object in such a way that height hangs low use
On.It climbs shaft tower and transferring position Shi Buying loses the protection of safety belt.In operation process, safety belt whether should fasten check at any time
Jail.Similar regulation also has specific requirement in the regulation regulation that country issues.
According to above-mentioned regulation, operating personnel falls in order to prevent, ensures personal safety when climbing ladder, operating personnel
Meeting wear safety belt is protected by the realization that is used alternatingly that enclosing belt and two protect rope, and often a upper lattice, will stop, accomplish fluently
Square safety belt, then the safety belt of lower section is removed, it constantly repeats, expends operating personnel many physical strength and energy.
In this case, it if operating personnel in order to save time, accelerates speed, is used it is possible that low extension is high, or
Person's enclosing belt and two protect the no exceptionally straight, protection of rope not in place the case where, once landing of slipping, to safety belt and operating personnel
It impacts very big.
Summary of the invention
The technical problem to be solved by the present invention is a kind of universal steelframe ladder climbing device is provided, to solve existing skill
The problem of art.
The technical scheme adopted by the invention is as follows: a kind of universal steelframe ladder climbing device, hook including handstand J-type and
Handle is hinged with handle at the hook portion of hook and straightway portion, the ladder cross bar that one end can mount hook portion after rotatable handle
It is stuck, safety belt hanging hole is provided on the handle other end, straightway minister's degree is greater than adjacent two ladders cross bar spacing.
Preferably, rubber block is provided at above-mentioned handle clamping ladder cross bar.
Preferably, it is provided in the hook portion of above-mentioned hook against block, is arcuate structure against block lower end, upper end is rotatably
It is connected to and adjusts on screw, adjust screw and be rotatably connected to hook portion vertically.
Preferably, above-mentioned hook straightway is retractable structure.
Preferably, above-mentioned straightway portion abuts against ladder cross bar face and is provided with rubber layer.
Beneficial effects of the present invention: compared with prior art, the present invention utilizes leverage, by human body own wt,
Make hook grip on ladder cross bar, so that operating personnel be made to be easy to climb；And reduce when lifting hand because bearing gravity on hand, device
Automatic to unclamp, which has enough mechanical strengths, and mechanics static load experimental performance is better than safety belt, in use, safety belt
Enclosing belt suspension on the apparatus and the moment is in the high real-time guard hung low state, realize to operating personnel, should
Tool sizes, using the tool, can remove from and safety belt enclosing belt is used alternatingly with flexible modulation, to adapt to different types of ladder
The tedious steps for protecting rope with two, when for climbing main transformer, can be such that the time spent originally is shortened within 20 seconds by clock more than 3 points,
The tool is while adequately protecting operating personnel, moreover it is possible to reduce the climbing time, improve operation effect, to mitigate operation labour
Intensity.The climbing that the present invention can be used for having the electric pole of ladder, steel tower, substation and building.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is of the invention against block junction schematic diagram.
Specific embodiment
With reference to the accompanying drawing and the present invention is described further in specific embodiment.
Embodiment 1: as Figure 1-Figure 2, a kind of universal steelframe ladder climbing device, 1 He of hook including handstand J-type
Handle 2, link up with 1 hook portion and straightway portion at handle 2 is hinged with by articulated shaft 10, one end can be by hook after handle 2 rotates
The ladder cross bar 3 of portion's mounting is stuck, and the safety belt hanging hole 4 of safety band, straightway minister's degree are provided on 2 other end of handle
Greater than 3 spacing of adjacent two ladder cross bars, handle 2 uses U-shaped structure, is symmetrically hinged on hook 1, stress equalization.
Preferably, above-mentioned handle 2 is clamped at ladder cross bar 3 and is provided with fixture block 9, and 9 surface of fixture block is provided with rubber block 5, energy
Stability and reliability that handle connects ladder cross bar are enough improved, climbing safety is improved.
