It is further ensured that the fixed effect of cat ladder.
Still further preferably, the bayonet includes sequentially connected upper card face, side card face and lower card face, the upper card
Protrusion is additionally provided with face and the lower card face.Protrusion further prevents cat ladder from being slided from spandrel girder, so as to further protect
Demonstrate,prove the fixed effect of cat ladder.In addition, the upper card face and the lower card face are arc, and the upper card face and the lower card face
Between vertical range along being gradually reduced towards the direction by nearside card face away from the side card, such design method to climb
Terraced bayonet is caught in and takes out more convenient and smooth.
Preferably, the bolt welding is on the spandrel girder.
Preferably, the both sides of the cat ladder are provided with guardrail, and the width of the guardrail is less than or equal to the width of the cat ladder.
Prevent from throwing accidentally during maintenance staff's cat ladder, further ensure the security performance of cat ladder.
It is further preferred that the guardrail can be folded towards the cat ladder.Idle state is in cat ladder when not in use
When, can will the guardrail of cat ladder both sides fold after hang on well enclosure, it is necessary to using when take conveniently, it is not necessary to saved when using
Space.
Preferably, the length of the cat ladder is more than the spandrel girder to the vertical range of the elevator car top.
Preferably, the distance between the width of the cat ladder and two described spandrel girders match.
Compared with prior art, the invention has the beneficial effects that：A kind of machine-roomless lift top layer maintenance of the present invention is used
Cat ladder, overhauls cat ladder, maintenance staff can be very easily to installing excessive top layer component such as traction machine, limit by the top layer
Fast device etc. is detected and maintenance, will not lead to not carry out regularly maintenance work because of difference in height.

Embodiment
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings.
Embodiment
With reference to Fig. 1 ~ Fig. 4, a kind of machine-roomless lift top layer cat ladder of the present embodiment, includes the use of state and idle shape
State, cat ladder 2 are that cat ladder 2 is in idle state when not in use, and cat ladder 2 is fixed on elevator shaft, is not take up space；Work as needs
When carrying out maintenance work, cat ladder 2 is removed from elevator shaft, the spandrel girder 1 of one end of cat ladder 2 and elevator shaft is connected, is climbed
The other end of ladder 2 is positioned in the car top of elevator, so that cat ladder 2 is fixed, facilitates maintenance staff by cat ladder 2 to draging
Draw machine etc. to be overhauled, realize the maintenance function of cat ladder 2, it is necessary to which the length of cat ladder 2 is more than spandrel girder 1 to the vertical of elevator car top
The distance between distance, the width of cat ladder 2 and two spandrel girders 1 match.
In the present embodiment, connector 3 is installed on spandrel girder 1, the upper end of cat ladder 2 is provided with matched with connector 3
Shackle member 5, cat ladder 2 is connected by shackle member 5 with connector 3, so that the upper end of cat ladder 2 can be rotationally connected with spandrel girder
On 1, specifically, connector 3 is bolt, and bolt welding is on spandrel girder 1, offering bayonet 6, bayonet 6 and spiral shell in shackle member 5
The outside diameter of bolt is adapted, and bayonet 6 includes sequentially connected upper card face 61, side card face 62 and lower card face 63, and upper card face 61 is with
Card face 63 is arc, and the vertical range between upper card face 61 and lower card face 63 is along the remote side card towards by nearside card face
Direction be gradually reduced, what such design method caused 2 bayonet 6 of cat ladder is caught in and takes out more convenient and smooth, in addition, on
Protrusion is additionally provided with card face 61 and lower card face 63, protrusion can be inserted according to actual needs on upper card face 61 and lower card face 63,
Bolt is firmly blocked during cat ladder 2 is used, so as to further prevent cat ladder 2 from being slided from spandrel girder, ensures cat ladder
Fixed effect, it is certainly, raised also to be taken out according to being actually needed from upper card face 61 and lower card face 63, with reference to the tool of bayonet 6
Body structure facilitates bayonet 6 to block bolt also conveniently to remove cat ladder 2.
In addition, the both sides of cat ladder are provided with guardrail 4, and the width of guardrail 4 is less than or equal to the width of cat ladder 2, and guardrail 4 can court
Folded to cat ladder 2, by setting guardrail 4, on the one hand can prevent maintenance staff from being thrown accidentally during cat ladder so as to ensure
The security performance of cat ladder 2, can by the guardrail of cat ladder both sides on the other hand when cat ladder is in idle state when not in use
Hung over after folding on well enclosure, it is necessary to using when take conveniently, it is not necessary to use time save space.
Operation principle：
During specifically used cat ladder 2, by the connector 3 i.e. bayonet 6 for the shackle member 5 that bolt is caught in 2 upper end of cat ladder, climb
The lower end of ladder 2 is positioned in the car top of elevator, so that maintenance staff very easily can such as drag to installing excessive top layer component
Draw machine, limiter of speed etc. to be detected and maintenance, will not lead to not to carry out regularly maintenance work because of difference in height.
