Abstract
The utility model discloses a cupula type safety scaling ladder which includes a ladder bed (5). The bottom end of the ladder bed (5) is at least provided with a cupula structure (7) and a screw. The cupula structure (7) is provided with a threaded sleeve. The cupula structure (7) is fixedly connected with the ladder bed (5) through a screw and the threaded sleeve. The cupula structure (8) in the middle part and the cupula structure (6) at the top end are pressed and sucked to the wall that the scaling ladder relies on. Thus, the scaling ladder can be fixed with the wall and the ground by a plurality of contact surfaces and having a higher safety factor is.
Description
Affiliated technical field
The utility model relates to a kind of fire ladder, especially a kind ofly is provided with the fire ladder that sucker structure tightens security.
Background technology
At present, fire ladder generally is that the top leans against on the metope of building when using, and the bottom then is against on the ground.And the metope and the ground of a lot of buildings are all very smooth now, are curtain wall or ceramic tile as metope, and especially when on metope and the ground water being arranged, fire ladder is easy to slide even slip, and is abnormally dangerous.In order to make fire ladder safer in use, the patent No. is that 95246772.0 utility model patent discloses a kind of fire ladder with the triangle spike, as Fig. 1, Fig. 2 and shown in Figure 3, this fire ladder comprises ladder 1, it is characterized in that: it is leg-of-mutton post piece 2 that the lower end of described ladder 1 is provided with the cross section, and the center of triangular column piece 2 is provided with the lower end that steady pin 3 is fixed on triangular column piece 2 ladder 2.The cross section of described triangular column piece 2 is an equilateral triangle; The periphery of described triangular column piece 2 is coated with one deck rubber skin.It contacts fixing reliable in use with ground, can not hurt sb.'s feelings.
The inventor finds that in practice there are following two shortcomings in above-mentioned fire ladder:
First and third dihedral spike complex structure, though certain anti-skidding effect is arranged, in use not with the power of ground and metope absorption, poor effect.
The second, at the medium position of fire ladder other are not set and can strengthen fixing and anti-skidding facility and structure.
Summary of the invention
The purpose of this utility model is the shortcoming that has potential safety hazard at present general fire ladder, a kind of fire ladder that has sucker structure is provided, thereby makes fire ladder more secure when used.
The technical scheme that the utility model adopted is: a kind of sucked type safety fire ladder, comprise ladder (5), described ladder (5) bottom is provided with at least one sucker structure (7), described ladder bottom is provided with screw rod, described sucker structure (7) is provided with swivel nut, and described sucker structure (7) is fixed together by screw rod and swivel nut with ladder (5).
In order to prevent that further fire ladder from sliding backward, at the middle part of described ladder (5) far from ground 1 meter to 1.5 meters, be provided with at least one sucker structure (8), this sucker structure (8) is fixedlyed connected with ladder (5) by an elastic rope (9).
For the fixed ladder top of the trellis, be respectively equipped with a sucker structure (6) in described ladder (5) both sides, top, the top of described ladder (5) is provided with screw rod, and described sucker structure (6) is provided with swivel nut, and described sucker structure (6) is fixed together by screw rod and swivel nut with ladder (5).Not the time spent, can unload sucking disc mechanism.
The middle part of described ladder (5) is respectively equipped with a sucker structure (8) far from the both sides at 1m to 1.5 meter, ground, and these two sucker structures (8) are fixedlyed connected with ladder (5) by an elastic rope (9) respectively.
During use, the fire fighter can press the ground of inhaling at building with the sucker structure (7) of bottom, simultaneously, the sucker structure (6) on top and the sucker structure (8) and the pressure at middle part are inhaled on the metope that fire ladder relied on, like this, fire ladder and metope and ground have a plurality of contact surfaces to be fixed, and safety factor is higher.
The beneficial effects of the utility model are: the first, the utility model all is provided with sucker structure in the middle part and the bottom of fire ladder, forms firm triangular structure and fire ladder is disagreed with rock and tilted.Especially when to the fire fighting of building water spray, under the situation that metope becomes very smooth, can guarantee effectively that the stable and ladder of fire ladder is gone up personnel's safety, guarantee finishing of fire extinguishing disaster relief task.
The second, the utility model has increased the contact area and the adhesive power on fire ladder and building wall and ground by sucker structure, particularly owing to be respectively equipped with sucker structure in the both sides of fire ladder middle part sustained height, these two suckers check and balance, and have improved the safety factor of fire ladder greatly.
Three, the utility model is simple in structure, and is with low cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 to Fig. 3 is the structural representation of background technology of the present utility model.
Fig. 4 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 4, a kind of sucked type safety fire ladder, comprise ladder (5), described ladder (5) bottom is provided with two sucker structures (7), described ladder bottom is provided with a screw rod, the upper end of described sucker structure (7) is provided with a swivel nut, and described sucker structure (7) is fixed together by screw rod and swivel nut with ladder (5).Not the time spent, can unload this sucker structure (7).
For the fixed ladder top of the trellis, be respectively equipped with a sucker structure (6) in described ladder (5) both sides, top, the top of described ladder (5) is provided with screw rod, and described sucker structure (6) is provided with swivel nut, and described sucker structure (6) is fixed together by screw rod and swivel nut with ladder (5).Not the time spent, can unload sucker structure (6).
The middle part of described ladder (5) is respectively equipped with a sucker structure (8) far from the both sides at 1m to 1.5 meter, ground, and these two sucker structures (8) are fixedlyed connected with ladder (5) by an elastic rope (9) respectively.
During use, the fire fighter can press the ground of inhaling at building with the sucker structure (7) of bottom, simultaneously, press suction on the metope that fire ladder relied on the sucker structure (8) at middle part and the sucker structure (6) on top, like this, fire ladder and metope and ground have a plurality of contact surfaces to be fixed, and safety factor is higher.
