Description
Technical field
The present invention relates to a kind of fire-fighting and rescue hook ladder, in particular to a kind of rolling-type hook ladder.
Background technique
In recent years, with the rapid development of social economy, fire brigade undertakes fire extinguishing, rescue, security, stability maintenance are appointed
Business is increasingly heavier.Fire-fighting rack is that commonly a kind of low latitude is ascended a height in fire fighting, rescue and daily workout for fire brigade
Operation equipment, mobility strong can effectively improve escape from fire effect and fire-fighting efficiency, reduce casualties and national wealth damage
It loses, the height of frequency of use, rescues the good of effect, be installed to fire brigade extensively.
The fire-fighting rack that fire brigade is equipped at present mainly has: 6 meters of short extension ladders, and 15 meter of 3 section aluminium alloy draws terraced, hook ladder,
Attic ladder etc. can according to circumstances set up rapidly fire-fighting rack and get through fire extinguishing and escape and rescue trunk, still after fireman reaches rescue site
These fire-fighting racks have this common feature: volume is big, weight weight, not foldable, needs more people to operate, as with vehicle equipment
It can be only placed at roof transport, exposing to the weather drenches with rain, and perishable deformation and performance decline (are all made of bamboo matter material in addition to aluminium-alloy ladder
Material).
Fire-fighting rope ladder can be wound, small in size, easy to carry, but could be used after can only fixing above fire escape,
Fireman can not set up from below, and use scope is narrow.Therefore, it is small in size to seek one kind, it is easy to carry, it can be under fire escape
The hook ladder just set up has great importance.
Summary of the invention
Based on described above, the invention proposes it is a kind of it is novel furl hook ladder, which is a collection composite PVC
Terraced arm, aluminium alloy stile, hook, the mechanical works that support leg is integrated.
The present invention realizes by the following technical solutions:
Several ladders vertical with terraced arm are arranged between two terraced arms in a kind of novel rolling-type hook ladder, including two parallel terraced arms
It pedals, terraced arm top is provided with hook.The ladder arm is made of the composite PVC material with shape memory function.In unused shape
Under state, the ladder arm cross section is planar structure and can furl around the center line parallel with stile；In a state of use, the ladder
Arm curling is notched columnar structured, the entire terraced arm lengths of notch perforation.
Further, the direction that the notch opens up is towards stile side.
Further, the central angle of the notch is 30 °~45 °.
It further, further include the support leg being arranged in pairs, the support to increase the stability when hook ladder uses
Foot setting is linked up with where direction on end face in stile direction.
Further, as a preferred embodiment, the support leg is hinged on stile end face.Hook ladder is in use, branch
Support foot is extended into and 90 ° of horn shape states of stile；When being not used, support leg is threaded to and stile parastate.
The beneficial effects of the present invention are:
1, the hook ladder ladder arm is made of the composite PVC material with shape memory function, has the characteristics that light-weight.No
In use, the hook ladder can be wound together, parking space is greatlyd save, it is easy to carry；In use, terraced arm is curled into band notch
Cylindrical shape, support entire hook ladder, realize to it is lower and on erection.
2, devise hinged support leg, when ladder is not used, can be folded into stile parallel shape, convenient for retracting；Make
Used time unscrews support leg, ladder can be prevented too close with wall, influence to climb；Further, since after ladder expansion
There are certain toughness and elasticity, support leg is also convenient for fireman's erection.

Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention will be further described.
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that described herein, specific examples are only used to explain the present invention, not
For limiting the present invention.
As shown in fig. 1~fig. 5, present embodiment discloses a kind of novel rolling-type hook ladder, including two parallel terraced arms 1, two
Several stiles 2 vertical with terraced arm 1 are set between terraced arm 1, and terraced 1 top of arm is provided with hook 3, is characterized in that, the present invention
Described in ladder arm 1 select the composite PVC material with shape memory function to be made (as patent publication No. CN104004304B institute is public
The material opened), under unused state, ladder 1 cross section of arm is planar structure and can be around the center coil of wire parallel with stile 2
It receives, as shown in Fig. 4~Fig. 5, occupies little space, be convenient for carrying；In a state of use, the terraced arm 1 is again rollable for band notch
10 it is columnar structured, as shown in Figure 1, the notch 10 penetrates through entire terraced 1 length of arm.
As preferred embodiment a kind of in the present embodiment, direction that the notch 10 opens up is towards 2 side of stile；Notch 10
Central angle 10a is 30 °~45 °.
It further include support leg 4 hinged in pairs as one of the present embodiment preferred embodiment, the support leg 4 is arranged
Where stile 2 towards 3 directions of hook on end face.Hook ladder is in use, support leg 4 is extended into stile 2 in 90 ° of horn shape states；
When being not used, support leg 4 is threaded to and 2 parastate of stile.
Since the hook ladder ladder arm is made of the composite PVC material with shape memory function, have the characteristics that light-weight.
When not in use, which can wind together, greatly save parking space, easy to carry；It is lacked in use, terraced arm is curled into band
Mouthful cylindrical shape, support entire hook ladder, realize to it is lower and on erection.
Above-described embodiment is presently preferred embodiments of the present invention, is not a limitation on the technical scheme of the present invention, as long as
Without the technical solution that creative work can be realized on the basis of the above embodiments, it is regarded as falling into the invention patent
Rights protection scope in.
