Connected with eight word links between rope.The closure door of the rope ladder head of traditional rope ladder, is a half-round metal ring, and respectively there is a hole at two ends
Hole.One end of closure door is fixed on the main support that rope ladder head is walked below line wheel, and closure door can be rotated, and closure door other end hole is hooked
On assistant support closure door hook.The closure door of rope ladder head can prevent rope ladder head from deviating from from conductor wire, play a part of protection.Envelope
Gate stop is hung needs staff directly to be operated with hand, could close closure door.During power failure operation, staff can stand directly on
Closure door hook is hooked on rope ladder head, and in livewire work, rope ladder head is transferred at conductor wire with insulation transmission rope, then
Rope ladder head is walked into line wheel again to hang on conductor wire, because rope ladder head closure door cannot be operated with insulated operating tool, work is only waited until
After making personnel in rope ladder climbing to rope ladder head, rope ladder head closure door could be closed.Staff climb rope ladder during, due to
The motion of human body, can cause conductor wire up-down vibration, rope ladder to rock, and because rope ladder head closure door is not closed, easily make rope ladder head
Walk line wheel to be come off from conductor wire, cause rope ladder from falling from high altitude, so as to the staff for causing climbing rope ladder also occurs high-altitude
Falling accident.
Utility model content
In order to solve technical problem present in background technology, the utility model proposes a kind of self-locking rope ladder.
The utility model proposes a kind of self-locking rope ladder, including preceding main support, rear main support, it is preceding walk line wheel, after walk line wheel,
Before walk line wheel installed in preceding main support top, after walk line wheel installed in rear main support top, preceding main support and rear main support pass through
The connection of crossbeam that multiple is parallel to each other, in preceding main support top curved into first half closed component, it is preceding walk line wheel sealed positioned at first half
Close in shape component；In rear main support top curved into later half closed component, after walk line wheel in the later half closed component；
Preceding self-locking plate is hinged with the opening of first half closed component, self-locking plate after being hinged with the opening of later half closed component,
Preceding draw piece two ends are connected with preceding self-locking plate and crossbeam front end respectively, rear draw piece two ends respectively with rear self-locking plate and crossbeam rear end phase
Even.
Further, preceding draw piece and rear draw piece are drawstring or pull bar.
Further, it is pipe in preceding main support and rear main support, preceding draw piece is located in preceding main support endoporus, rear draw piece position
In in rear main support endoporus.
Further, multiple crossbeam grooves are offered on preceding main support and rear main support, crossbeam is arranged in crossbeam groove, horizontal
Beam can be moved up and down with respect to crossbeam groove.
Further, it is provided between preceding main support and preceding self-locking plate for the automatically reset preceding reset bullet of preceding self-locking plate
Spring, is provided with for the automatically reset rear back-moving spring of rear self-locking plate between rear main support and rear self-locking plate.
The utility model provide a kind of self-locking rope ladder, when people is stepped on crossbeam, due to the weight of people, make preceding draw piece and
Draw piece is pulled down afterwards, and preceding self-locking plate and rear self-locking plate close off the opening of first half closed component and later half closed component,
Walked before can preventing line wheel and after walk line wheel and come off from conductor wire.When people is not stepped on crossbeam, preceding self-locking plate and it is rear from
The jam plate return in the presence of preceding back-moving spring and rear back-moving spring respectively.The utility model clever structure, and have auto-lock function,
Security is good.
Brief description of the drawings
Fig. 1 be the utility model proposes self-locking rope ladder schematic diagram；
Fig. 2 is the side view of Fig. 1.
Specific embodiment
The utility model is described in detail with reference to instantiation, it should be appreciated that embodiment is served only for explanation originally
Utility model, it is any modification made on the basis of the utility model, equivalent rather than for being defined to the utility model
Replacement etc. is in protection domain of the present utility model.
As depicted in figs. 1 and 2, the utility model proposes a kind of self-locking rope ladder, including preceding main support 1, rear main support 2,
Before walk line wheel 10, after walk line wheel 20, it is preceding walk line wheel 10 be arranged on the top of preceding main support 1, after walk line wheel 20 installed in rear main support 2
Top, preceding main support 1 and rear main support 2 are connected by multiple crossbeams 3 being parallel to each other.Preceding main support 1 and the structure of rear main support 2
