Description
Technical field
The present invention relates to a kind of preventing mistake scrambling cat ladders.
Background technology
With the development of power technology, the volume of electrical equipment is increasing, and electricity is overhauled and safeguarded for convenience of professional
Gas equipment, many large electric equipment are all furnished with cat ladder on the body, but some irrelevant personnel may be climbed and be swashed without authorization
Ladder easily causes safety accident.Traditional way is that warning-signs such as eye-catching " forbid climbing, Keep Clear-High Voltage " are arranged on cat ladder
Will, but effect is less apparent.Door with climbing ladder is added on some cat ladders on cat ladder, but door with climbing ladder is usually shorter, preventing mistake scrambling
Effect it is poor.
Invention content
The purpose of the present invention is to provide a kind of cat ladders that can effectively prevent irrelevant personnel mistake scrambling.
To achieve the above object, preventing mistake scrambling cat ladder of the invention includes spaced perpendicular support and is hinged between perpendicular support
Stull, the stull forms parallelogram mechanism with perpendicular support, and the cat ladder has by making stull swing so that two perpendicular supports
It is close to each other to pack up position, also have swung by stull so that two it is perpendicular support the expansion position being located remotely from each other, in two of which stull
Equipped with interconnection so that cat ladder is maintained at the lock piece for packing up position or stull and is equipped with interconnection so that cat ladder is protected with perpendicular support
It holds in the lock piece for packing up position.The present invention can make cat ladder can by the way that the perpendicular support and stull of cat ladder to be arranged to movable structure
Pack up position and expansion position to be in, and wherein in two stulls or stull and setting in one of them perpendicular support be connected with each other with
So that cat ladder is kept the lock piece of collapsed state, cat ladder is packed up after operating personnel's use, thus avoids irrelevant personnel
From cat ladder climbing to electrical equipment, it is therefore prevented that safety accident occurs because of mistake scrambling.
Further, the lock piece includes the lock ring passed through for the lock bridge of padlock and the buckle for being connect with lock ring,
The buckle is equipped with the perforation passed through for lock ring.This is because the installation of this lock piece is more convenient, pass through lock ring and button
Plate, which mutually fastens, can make cat ladder keep collapsed state, and the production and processing of lock ring and buckle is easier, and cost is relatively low.
Further, the buckle is hinged in stull, and when the cat ladder is in expansion position, stull is prolonged in the horizontal direction
It stretches, the hinge axes of the buckle are horizontally extending.So, buckle can be rotated around hinge axes, packed up
When cat ladder, buckle will not generate interference with perpendicular support and stull, can preferably be fastened with lock ring after cat ladder is packed up, reach lock
Purpose only.And when cat ladder is in expansion position, buckle is vertically sagging, is climbed upwards by cat ladder in operating personnel
When, it is not easy to it is suspended to.
Further, the perpendicular support and stull are hinged by active pin shaft.
Further, the perpendicular support and stull have respective swinging plane, and the swinging plane of perpendicular support and stull has
Interval.So, stull will not be interfered with each other with perpendicular support when swinging, and when cat ladder is packed up, and two perpendicular supports can be complete
It touch, compares and save space.

Specific implementation mode
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of the preventing mistake scrambling cat ladder of the present invention in the description of the present invention, needs as shown in Figure 1 to Figure 2
Illustrate, the orientation of the instructions such as term "upper", "lower", "left", "right", "vertical", "horizontal", "front", "rear" or position are closed
System is merely for convenience of the description present invention, rather than indicates or imply and is signified to be based on the orientation or positional relationship shown in the drawings
Device or element must have a particular orientation, with specific azimuth configuration and operation, therefore should not be understood as to the present invention
Limitation.
Above-mentioned preventing mistake scrambling cat ladder includes spaced two equal lengths and the perpendicular support 1 that is mutually parallel, two perpendicular supports 1
Between be connected with multiple stulls 2 being mutually parallel, each stull 2 is hinged on by the articulated structure at 2 both ends of stull in perpendicular support 1,
The stull 2 forms parallelogram mechanism with perpendicular support 1, and stull 2 can make cat ladder that there is perpendicular support 1 mutually to lean on around 1 rotation of perpendicular support
The 1 expansion position being located remotely from each other is supportted in close packing up position and erect.When cat ladder is in expansion position, the lower face of two perpendicular supports 1 is concordant, stull
2 extend along horizontal direction, and the lock piece so that cat ladder keeps packing up position is connected with each other wherein being respectively equipped in two stulls 2.
Above-mentioned lock piece is made of the lock ring 5 that is passed through for the lock bridge of padlock 6 and the buckle 4 for being connect with lock ring 5, is detained
Plate 4 and lock ring 5 are respectively fixedly connected with by welding or screw in two stulls 2, and position can be in cat ladder and pack up position
When scribing line determine.There is buckle 4 hinged movable part 41 on it, movable part 41 to be equipped with the perforation passed through for lock ring 5, activity
Portion 41 can be rotated around articulated shaft, and the articulated shaft of movable part 41 is consistent with the extending direction of crossbeam 2.Movable part 41 has and climbs
The parallel state of plane where terraced also has the state to form an angle with plane where cat ladder, to keep away to coordinate with lock ring 5
Unlocking link 5 will not be interfered when cat ladder being made to pack up by buckle 4.Buckle 4 and lock ring 5 can prevent cat ladder from beating automatically after fastening
It opens, when cat ladder is in expansion position, the hinge axes direction of movable part 41 and the length direction of stull 2 are all horizontal direction.
In the present embodiment, above-mentioned perpendicular support 1 and stull 2 are hinged by active pin shaft 3.Above-mentioned perpendicular support 1 and stull 2 have
There are respective swinging plane, i.e., perpendicular support 1 and stull 2 to mutually stagger in the longitudinal direction, so, when cat ladder is packed up, erects support 1
Swing with stull 2 will not interfere, and when cat ladder is packed up, and two perpendicular supports 1 can touch completely, compare and save space.
Perpendicular support 1 on the right of the preventing mistake scrambling cat ladder of the present invention is fixed on electrical equipment, and cat ladder is in pack up position, the left side at this time
Perpendicular support 1 and the perpendicular support 1 on the right it is close to each other, and the padlock 6 by being threaded through on buckle 4 and lock ring 5 locks, and people can not pass through
Cat ladder is climbed upwards, avoids the generation of safety accident.When professional needs to overhaul electrical equipment by cat ladder,
Padlock 6 is taken, cat ladder is unfolded, you can is climbed upwards for the operating personnel of profession, equipment is overhauled.
In other embodiments, lock piece can be other types, such as spring lock, can lead to after stull is swung in place
Cross the locking that spring lock realizes cat ladder；Or a lock ring is respectively set in two stulls, when cat ladder is in and packs up, padlock can
Also cross two lock rings, cat ladder to be locked.
In other embodiments, lock piece, which can have on other installation forms, such as stull, is equipped with lock ring, erects in support
Corresponding buckle is installed, cat ladder is in when packing up, and lock ring and buckle are mutually fastened and connected.
