Description
Technical field
The invention belongs to locomotive corollary equipment field, specifically a kind of large automobile retractable cat ladder.
Background technique
Now, large automobile is many kinds of, such as crane, crane, large-sized truck etc., what is common is that figure is big,
Compartment is higher apart from ground, and people are when maintenance, handling etc. are got on or off the bus, it usually needs go to climb by human body itself, Huo Zhexu
The climbing object such as ladder is separately removed, in this way since ladder is not mating fixation, ladder is not capable of fixing, and is easy back skating, and climbing personnel are easy
Fall down danger, meanwhile, for normal ladder, can not free extension, and occupied space is big, is unable to satisfy people and takes with vehicle
The demand of band brings user many inconvenience.
Summary of the invention
To solve, large automobile now is climbed up and down using the easy back skating of common ladder, occupied space is big and inconvenient to carry asks
Topic, the present invention provide a kind of large automobile retractable cat ladder.
The present invention is realized by following technical proposals.
A kind of large automobile retractable cat ladder, characterized in that be bracket, I and of expansion bracket of groove profile steelframe including two sides
Expansion bracket II, I front end two sides of expansion bracket are mounted on roller I, and two roller Is are stuck in the left and right groove profile steelframe of bracket；It is flexible
II front end two sides of frame are mounted on roller II, and two roller IIs are stuck in the left and right groove profile steelframe of expansion bracket I；II two sides of expansion bracket
Steelframe on be provided with long hole, horizontal in long hole to be inserted with bar, bar is fixed on expansion bracket I；It is horizontal on expansion bracket I and expansion bracket II
To being evenly equipped with several pedals.
The large automobile retractable cat ladder, wherein the bracket lower part is equipped with fixed block, and fixed block rear side is successively
It is connected with tension spring and connecting rod, is connected with rotatable hook on rear side of connecting rod.
The large automobile retractable cat ladder, wherein the back-end support two sides are fixed with handrail.
The large automobile retractable cat ladder, wherein II rear end of expansion bracket is equipped with rubber base plate.
The beneficial effects of the invention are as follows：1, it solves the problems, such as that truck conspicuity marking maintenance, handling etc. are got on or off the bus to ascend a height, protect
The safety of barrier personnel climbing；2, ladder is scalable, lower extension, space is saved, convenient for storage；3, bracket and the big frame connection of car body are solid
It is fixed, it is versatile, and it is equipped with handrail, guarantee the firm fixing of ladder；4, expansion bracket II, expansion bracket I and bracket socket are flexible,
When maintenance dismantle, decompose it is convenient；5, when retracted mode, expansion bracket is locked by spring, hook, prevents expansion bracket automatic
It skids off, high safety.
Detailed description of the invention
Fig. 1 is contraction state schematic diagram of the invention.
Fig. 2 is overlooking structure diagram of the invention.
Fig. 3 is stretching status diagram of the invention.
In attached drawing：1, roller II, 2, roller I, 3, bracket, 4, expansion bracket I, 5, expansion bracket II, 6, handrail, 7, bar, 8,
Fixed block, 9, tension spring, 10, connecting rod, 11, hook, 12, pedal, 13, pedestal, 14, long hole.
Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
As shown in the picture, a kind of large automobile retractable cat ladder is that the bracket 3 of groove profile steelframe, two sides are equal including two sides
It is the expansion bracket II 5 of groove profile steelframe for the expansion bracket I 4 of groove profile steelframe and two sides, the front end two sides of expansion bracket I 4 are mounted on
Roller I 2, two roller Is 2 are stuck in the left and right groove profile steelframe of bracket 3；The front end two sides of expansion bracket II 5 are mounted on roller II
1, two roller IIs 1 are stuck in the left and right groove profile steelframe of expansion bracket I 4；Strip is provided on the steelframe of II 5 two sides of expansion bracket
Long hole 14, it is horizontal in long hole 14 to be inserted with the bar 7 being fixed on expansion bracket I 4；It is laterally homogeneous on expansion bracket I 4 and expansion bracket II 5
It is intervally distributed with several pedals 12.Fixed block 8 is installed in 3 lower part of bracket, be connected with tension spring 9 on rear side of fixed block 8 in turn and is connected
Bar 10 is connected with rotatable hook 11 on rear side of connecting rod 10.
This large automobile retractable cat ladder, first bracket 3 are fixed on the big frame of car body of large automobile, when needing to stretch out,
By the rear end of dragging expansion bracket II 5, being rolled by roller II 1, expansion bracket II 5 is moved backward relative to expansion bracket I 4, until
The left edge of long hole 14 is contacted with the bar 7 being fixed on expansion bracket I 4, and at this moment expansion bracket II 5 drives expansion bracket I 4 to move back
Dynamic, until the roller I 2 of expansion bracket I 4 is stuck in the rear end of bracket 3, at this moment expansion bracket II 5 and expansion bracket I 4 are fully extended and rotate
Lower extension by height from the ground, and then adjusts the relative position of bar 7 and long hole 14, to realize that the length of ladder is adjusted, leads to
It crosses II 5 rear end of expansion bracket and rubber base plate 13 is installed, realize the anti-skidding and damping of bottom.Operating personnel can pass through about 12 pedal
It climbs, it is convenient and efficient, by assisting the handrail 6 of 3 rear end sides of bracket in, make personnel safety or more.When being finished ladder, need to retract
When, it is successively retracted in bracket 3 by being manually lifted up expansion bracket II 5 and expansion bracket I 4, passes through Rotary hanging hook 11 to setting shape
State makes it hang over II 5 rear end of expansion bracket, by the forward pulling force of tension spring 9, avoids locomotive II 5 He of expansion bracket in the process of moving
Expansion bracket I 4 skids off automatically, causes peril, and last pedestal 13 is stuck in the rear end of bracket 3, plays secondary guarantee.
Space is saved in this large automobile retractable cat ladder, scalable storage；Stability is good, can ensure that operating personnel climbs
When safety, and can be suitably used for any large automobile, it is versatile.
