To achieve these goals, the technical solution adopted in the present invention is:
A kind of elevator fire extinguishing system, the lift car being arranged in elevator is supported by support means；One car roller is installed on bottom lift car and drives described support means, makes lift car rise or fall；The hoistway wall of described elevator is provided with opening at two floors, and described opening is closed by two elevator doors, falls two elevator doors and leaving certain gaps uncovered by the economic plan between two floor base plates after closedown；One extinguishing device is installed on down two floors, and extinguishing device ejection fire extinguishing water is assembled at two floor base plates and flows to the elevator car roof in elevator from breach, is finally collected at elevator shaft bottom；Described elevator car roof edge is provided with guard member, and described guard member is peripheral around support means, and elevator car roof is provided with cross bar, and guard member is less than cross bar, and described extinguishing device is additionally provided with volume control device.
Wherein, described breach is the slightest equal to 6cm.
Wherein, the shape of cross section of described guard member is V-type.
Wherein, described guard member is U-shaped guard member.
Wherein, described guard member be shaped as square.
The invention have the benefit that
Use guard member to prevent fire extinguishing water to be sprayed in support means, thus ensure the pull strength between support means and car roller, it is ensured that elevator fire extinguishing system can be properly functioning during fire-fighting uses.

Detailed description of the invention
Describe the present invention below with reference to detailed description of the invention shown in the drawings.But these embodiments are not limiting as the present invention, structure, method or conversion functionally that those of ordinary skill in the art is made according to these embodiments are all contained in protection scope of the present invention.
Elevator fire extinguishing system is a kind of elevator that can use the longer time in a fire, and the electronic devices and components of the most described elevator can waterproof, lift car fire prevention or possess special fireproofing pattern.
Fig. 1 show the elevator fire extinguishing system of embodiment of the present invention.Lift car 1 and counterweight 2 it is provided with in elevator 10.Described lift car 1 and counterweight 2 are driven by support means 3.Described lift car 1 and counterweight 2 can be vertical in elevator 10 by powered support means 3 movement.Described lift car 1 and counterweight 2 are driven by car roller 11 and counterweight roller 12 respectively.Described car roller 11 is installed on bottom lift car 1 and makes car roller 11 can drive described lift car 1, and same counterweight roller 12 is installed on the top of counterweight 2 so that counterweight roller 12 can drive counterweight 2.
The hoistway wall 6 of described elevator 10 is at each floor, the floor 9.1(that such as falls has down a floor base plate 8.1) and two floor 9.2(there are down two floor base plates 8.2) position is provided with opening, described opening can respectively by elevator door 5.1 and two elevator doors 5.2 close, elevator door after described closedown and a floor base plate, leaving certain gaps uncovered by the economic plan 18 between two floor base plates of falling.One extinguishing device 13 is installed on down at two layers, the most as depicted fall two floors 9.2.Described extinguishing device 13 is installed on down the purpose of two floor 9.2 positions and is so that fire extinguishing water 14 can arrive fire location to greatest extent.Extinguishing device 13 ejection fire extinguishing water 14 is assembled in two floor base plate 8.2 positions and wanders from indentation, there, in flowing to elevator 10 at least partially and fall in elevator car roof, as shown in Figure 1.Fire extinguishing water 14 continues to be finally collected at elevator shaft bottom 7 toward dirty from elevator car roof.
In described elevator 10 fire extinguishing water number amount number affected by following factor: from the total amount of the fire extinguishing water 14 that extinguishing device 13 flows out, and two elevator doors 5.2 and the size of breach between two floor base plates 8.2, described breach is the slightest equal to 6cm, if breach is too big, it is properly functioning that other materials affect elevator in easily calling in elevator.Fire extinguishing water 14 total amount flowed out from extinguishing device 13 is the most, then hydraulic pressure is the biggest, just has more water to flow in elevator 10 under bigger pressure.Additionally, flow to the fire extinguishing water 14 of elevator 10 also by lift car 1 with difference in height is affected between two floors 9.2.Car top 15 is the most remote with the distance of two floor base plates 8.2, then be sprayed at fire extinguishing water 14 flow velocity of car top 15 from breach infiltration the fastest.Described extinguishing device is additionally provided with volume control device (not shown).
Fig. 2 a-2d shows a kind of guard member 16, described guard member 16 is installed on the edge of car top, guard member is peripheral around support means, prevent support means put out a fire water spray and affect use, the height 17 of guard member 16 is relevant with support means 3, and support means 3 can be played protective action by guard member 16.First, the height 17 of described guard member 16 must be sufficiently high so that it is prevented from the fire extinguishing water 14 that support means 3 is sprayed and is sprayed onto.Secondly, the height of guard member 16 again can not be the highest, the highest if described lift car 1 can be affected again in uphill process.In one embodiment, the height of described guard member 16 is set to 50cm.
Refering to shown in Fig. 2 a, the shape of cross section of described guard member 16 is V-type, and the guard member 16 of this shape is prone to processing.
Refering to the square guard member 16 shown in Fig. 2 b, support means 3 can be played protective action from all directions by described guard member 16.
Refering to the U-shaped guard member 16 on the side inclined-plane shown in Fig. 2 c, this guard member 16 includes inclined-plane, uses the guard member 16 of this structure to need a higher height 17 just can play the protective action to support means 3.
Refering to the U-shaped guard member 16 shown in Fig. 2 d, the guard member 16 of this structure is similar to the structure of guard member 16 shown in Fig. 2 a.But the cross section of this embodiment guard member 16 is U-shaped.
Guard member 16 described in all embodiments of Fig. 2 a-2d can be from both direction ballistic support device 3.The most in some embodiments, the key area of described support means 3 is protected by guard member 16.
Refering to the structural representation of the lift car 1 shown in Fig. 3, described lift car includes sidewall 30, rear wall 29 and car door 4.Being also shown for described support means 3 in Fig. 3, described support means 3 is protected by guard member 16, show the one of which mounting structure schematic diagram of guard member 16 refering to Fig. 4.Guard member 16 shown in Fig. 4, less than the cross bar 21 of car top 15, so ensure that guard member 16 does not interferes with the normal rising of lift car 1.
It is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should be using description as an entirety, technical scheme in each embodiment can also form, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that.
The a series of detailed description of those listed above is only for illustrating of the feasibility embodiment of the present invention; they also are not used to limit the scope of the invention, and all equivalent implementations or changes made without departing from skill of the present invention spirit should be included within the scope of the present invention.
