Description
Technical Field
The invention belongs to the technical field of ladder climbing equipment, and relates to types of universal steel frame ladder climbing equipment.
Background
The ladder stand is the common auxiliary assembly of electric power industry, and the place that needs the ascending height of mainly used fixed equipment, for example transformer substation main transformer, type pole framework of transformer substation, transmission line shaft tower, building etc..
In above-mentioned equipment, when needing to overhaul and maintain, each professional team such as operation, maintenance, experiment all can carry out professional experiment and maintenance to equipment, can go up to the equipment top through the cat ladder in the maintenance process and carry out work.
Q/CSG510001-2015 electric power safety work regulation of south China Power grid Limited company 20.2.3 provides that when the scaffold works on a scaffold without a railing and the height exceeds 1.5m, a safety belt is used or other reliable safety measures are taken. 20.2.2 specifies that the harness should be used in a high hang down manner and should not be tied to moving, sharp or loose objects. The protection of the safety belt is not lost when the tower is climbed and the position is transferred. In the process of operation, whether the safety belt is fastened or not should be checked at any time. Similar regulations, also have specific requirements in the regulations promulgated by the country.
According to above-mentioned regulation, the operation personnel in the climbing when the cat ladder, in order to prevent to fall, guarantee personal safety, the operation personnel can wear the safety belt, and the alternative use through enclosing pole area and two guarantors rope realizes the protection, and every check of going up will stop, makes the top safety belt, takes off the safety belt of below again, and is constantly repeated, consumes a lot of physical power and vigor of operation personnel.
In this case, if the operator is to save time and speed up, the operator may have a low hook height, or the boom belt and the secondary protection rope are not straight and the protection is not in place, and slips after falling off, so that the impact on the safety belt and the operator is very large.
Disclosure of Invention
The invention aims to solve the technical problem of providing types of universal steel frame ladder climbing equipment to solve the problems in the prior art.
The technical scheme includes that types of universal steel frame ladder climbing equipment comprises an inverted J-shaped hook and a handle, wherein the handle is hinged to a hook portion and a linear section portion of the hook, the ladder climbing cross rod hung by the hook portion can be clamped by the end after the handle is rotated, a safety belt hanging hole is formed in the other end of the handle, and the length of the linear section portion is larger than the distance between two adjacent ladder climbing cross rods.
Preferably, the rubber block is arranged at the position of the cross rod of the handle clamping ladder stand.
Preferably, a leaning block is arranged in the hook part of the hook, the lower end of the leaning block is of an arc-shaped structure, the upper end of the leaning block is rotatably connected to an adjusting screw, and the adjusting screw is vertically and rotatably connected to the hook part.
Preferably, the straight section of the hook is of a telescopic structure.
Preferably, the straight line section part is provided with a rubber layer against the cross rod surface of the adjacent ladder stand.
The invention has the beneficial effects that: compared with the prior art, the invention utilizes the lever effect and the self weight of the human body to tightly buckle the hook on the cross rod of the ladder stand, thereby leading the operator to easily climb; when the tool is used for climbing a main transformer, the time spent originally can be shortened to be within 20 seconds from 3 minutes or more, the tool can fully protect operating personnel, the climbing time can be shortened, the operation efficiency is improved, and the operation labor intensity is reduced. The climbing device can be used for climbing poles, iron towers, transformer substations and buildings with the climbing ladder.

FIG. 2 is a schematic view of the abutting block joint of the present invention.
Detailed Description
The invention is further described with reference to the figures and the specific embodiments.
Embodiment 1 as shown in fig. 1-2, kinds of general steel frame ladder climbing equipment comprises an inverted J-shaped hook 1 and a handle 2, wherein a hook portion and a linear section portion of the hook 1 are hinged to the handle 2 through a hinge shaft 10, a ladder climbing cross rod 3 hooked by the hook portion can be clamped by the end after the handle 2 rotates, a safety belt hanging hole 4 for hanging a safety belt is formed in the other end of the handle 2, the length of the linear section portion is larger than the distance between two adjacent ladder climbing cross rods 3, the handle 2 is of a U-shaped structure and symmetrically hinged to the hook 1, and stress is balanced.
Preferably, 2 joint cat ladder horizontal poles of above-mentioned handle 3 departments are provided with fixture block 9, and 9 surfaces of fixture block are provided with rubber block 5, can improve the stability and the reliability that the handle joint connects the cat ladder horizontal pole, improve the climbing security.
Preferably, be provided with in the hook portion of above-mentioned couple 1 and lean on piece 6, lean on 6 lower extremes of piece to be the arc structure, the upper end is rotatably connected on adjusting screw 7, during the connection, adjusting screw 7 lower extreme is provided with ring channel 13, and it is spacing that the lower extreme inserts to lean on 12 anticreep round pins that stretch into through the side behind the blind hole that leans on piece 6, and adjusting screw 7 is vertical rotatably to be connected in hook portion, leans on 6 lower extremes of piece to be provided with non-slip rubber layer 11, improves and articulates stability and reliability.
