Description
Technical field
The utility model relates to a kind of climbing instrument, specifically a kind of Portable insulation ladder.
Background technology
In the engineerings such as power supply, telecommunications, electric, water power, often need to carry out altitude hot-line operation, insulating ladder need to be used in the scene of climbing.Conventional insulating ladder is to adopt high temperature polymerization pultrusion manufacturing process, selects Epoxy Resin formed material to be made.The characteristics such as that insulating ladder has is non-conductive, corrosion-resistant, low water absorption, good flame resistance, high-strength, lightweight.The kind of insulating ladder is a lot, can be divided into the single ladder of insulation, insulated flexible ladder, insulation ring ladder, insulate and close ladder etc., to use in the working site of varying environment.But existing insulating ladder is mostly vertical ladder, space hold volume is larger, needs large wagon box in handling process, is inconvenient to transport; Some scene of climbing is not applicable to straightening terraced position, and operating personnel also needs to use insulating ladder.Existing insulation vertical ladder cannot be adjusted to cat ladder and use, and to operating personnel, increased the waste that work load also causes material.
Utility model content
The utility model technical issues that need to address are to provide a kind of Portable insulation folding ladder, collapsible when not using, and reduce volume, are convenient to carrying; While using at the construction field (site), can be adjusted to vertical ladder, can also be adjusted to cat ladder and use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
Portable insulation folding ladder, comprises some groups of terraced groups of connecting by linkwork, and every group of ladder group comprises two terraced bars that be arranged in parallel and be connected at least one stile between two terraced bars, and linkwork is arranged between the terraced bar two ends of adjacent ladder group; Described stile is Qian type structure, and two free ends of Qian type stile are arranged on terraced bar inner side by angle type spring hinge respectively; The terraced bar bottom of described bottom ladder group is by the hinged hook of bearing pin.
Improvement of the present utility model is: in the terraced bar that described Portable insulation folding ladder connects from beginning to end, wherein the top of a terraced bar is set to arc-shaped protrusions structure, the bottom of another root ladder bar is made as the groove structure mutually equipped with arc-shaped protrusions, two terraced bars by cross-under the bearing pin between arc-shaped protrusions and recess sidewall hinged; Described linkwork comprises and is fixedly installed on the latch in arc-shaped protrusions and is fixedly installed on toothholder mutually equipped with latch on recess sidewall inner face; Described toothholder changes position by being arranged on the regulating handle of recess sidewall outer face.
Owing to having adopted technique scheme, the technological progress that the utility model is obtained is:
The utility model is collapsible when not using, and reduces volume, is convenient to carrying; While using at the construction field (site), both can be adjusted to vertical ladder, and can also be adjusted to cat ladder and use.The Qian type stile of installing with angle type spring hinge between two terraced bars, when being adjusted to cat ladder use, safe and reliable, the site environment factor that reduced to climb is climbed the impact in space on staff.The hook that the terraced bar bottom of the terraced group of bottom arranges can increase the frictional force on terraced bar and ground when doing vertical ladder use, vertical ladder is used safer, can also when doing cat ladder use, open the top of catching on by climbing object.Between ladder group, by linkwork, connected, facilitate the folding of insulating ladder.When opening Portable insulation folding ladder, the latch arranging in the arc-shaped protrusions of terraced bar one end and the toothholder of groove inwall one side setting regulate by the regulating handle in groove walls outside, and latch and toothholder are coordinated, simple in structure, firm, easy to operate.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
A Portable insulation folding ladder, is comprised of some groups of ladder groups 1, between ladder group 1, by linkwork 2, connects.As shown in Figure 1, ladder group 1 comprises between 101, two terraced bars 101 of two terraced bars that be arranged in parallel and is provided with at least one stile 102, and stile 102 is Qian type structure, and two free ends of stile 102 are arranged between two terraced bars 101 by angle type spring hinge 103.Angle type spring hinge 103 only has two kinds of duties, and a kind of is closure state, and another kind is full open position, and the angle that angle type spring hinge 103 is opened is completely 90 °.The terraced bar bottom of bottom ladder group 1 arranges a hook 3, and hook 3 is hinged on terraced bar bottom by bearing pin.
In end to end terraced bar, wherein a terraced masthead end is provided with arc-shaped protrusions 104, another root ladder bar bottom is provided with the groove 105 matching with arc-shaped protrusions 104, groove 105 sidewall one end are provided with 106, two terraced bars of bearing pin and are connected with the bearing pin 106 between groove 105 sidewalls in arc-shaped protrusions 104 by cross-under.
Linkwork 2 as shown in Figure 4, comprise the latch 203 being arranged in arc-shaped protrusions 104 and be arranged on the toothholder 202 matching with latch 203 on groove 105 sidewall inner faces, toothholder 202 can carry out adjusting position by being arranged on the regulating handle 201 of groove 105 sidewall outer faces.
The Portable insulation folding ladder using as vertical ladder as shown in Figure 2, the hook 3 that the terraced bar bottom of closed bottom ladder group 1 arranges, angle type spring hinge 103 is in Operating In Persistent Current Mode state, open successively terraced group of every joint, regulate the regulating handle 201 in linkwork 2 concave cell wall outsides, make the latch 203 in arc-shaped protrusions enter into the toothholder 202 being arranged in groove walls, guarantee to become two parallel straight lines after the terraced terraced bar of organizing of every joint connects.Realize the use of vertical ladder.
The Portable insulation folding ladder using as cat ladder as shown in Figure 3, is opened the hook 3 being hinged on terraced bar 101, is fixedly connected with each joint ladder group 1, guarantees that the terraced bar that respectively saves after being fixedly connected with becomes two parallel straight lines.Open the angle type spring hinge 103 that connects terraced bar 101 and stile 102, make angle type spring hinge 103 keep the second duties, at this moment 102 one-tenth upright positions of terraced bar 101 and stile are fixed.Hook 3 is suspended on to be climbed on thing, and operating personnel upwards scales a ladder, and their gravity produces pressure to stile 102, thereby angle type spring hinge 103 is subject to downward pulling force, can not get back to closure state.The utility model is used as cat ladder, safety, reliably, easily realizes.
