Abstract
The utility model discloses an underbeam structure of an elevator without a machine room. The underbeam structure of the elevator without the machine room comprises an underbeam body, two safety gear blocks, two guide shoes and two car platform rope sheaves, wherein the underbeam body is horizontally arranged; the two safety gear blocks, the two guide shoes and the two car platform rope sheaves are arranged on the underbeam body; one of the two guide shoes is arranged at the right side of one end of the underbeam body; the other guide shoe is arranged at the left side of the other end of the underbeam body; two cant beams of which the top faces are parallel and level with the top face of the underbeam body are respectively and horizontally welded at the left side and the right side of the underbeam body; and the cant beams and the underbeam body are arranged at a certain included angle. The underbeam structure of the elevator without the machine room disclosed by the utility model is higher in strength, and moreover, the stability when an elevator car runs can be enhanced.
Description
Technical field
The utility model relates to the lift facility technical field, relates in particular to girder construction under a kind of machine-roomless lift.
Background technology
The elevator car frame of present machine-roomless lift generally all constitutes by a car frame underbeam with the upright beams of two sedan-chair framves, and wherein car frame underbeam is horizontally set on the bottom of lift car, and the bottom of the upright beam of two sedan-chair framves is fixedly connected on the car frame underbeam two ends respectively.
Yet, existing machine-roomless lift underbeam (being above-mentioned car frame underbeam) mostly is a straight beam structure, its with at the bottom of the car between be at 4 and contact, contact surface is little, and the underbeam of this structure can cause the upright beam of sedan-chair frame to be installed in the position (underbeam is not in the car center-of-gravity position yet) of departing from the car center of gravity, namely the line of centres of the upright beam of two sedan-chair framves and car center of gravity be not on same straight line, so can cause elevator car when safety tongs moves that car guide rail is produced big overturning couple, increase the potential safety hazard of elevator.
The utility model content
The utility model purpose is: at the problems referred to above, provide a kind of intensity height, can strengthen girder construction under the machine-roomless lift of elevator cage operation stability.
The technical solution of the utility model is: girder construction under a kind of machine-roomless lift, the underbeam body that comprises horizontal arrangement, and be arranged on two safety gear blocks on this underbeam body, two and lead rope sheave at the bottom of boots and two sedan-chairs, described safety gear block is provided with safety tongs, one of them is led boots and is arranged on described underbeam body one end right side, another is led boots and is arranged on described underbeam body other end left side, the equal horizontal welding in the left and right sides of described underbeam body is connected to its end face and the end face of this underbeam body mutually concordant cant beam, described cant beam and underbeam body layout in a certain angle.
The bottom midway location of described underbeam body is provided with buffing pad.
The utility model has the advantages that: girder construction under this machine-roomless lift that the utility model provides, it adopts the version of cross coupling, during concrete the application, with the bottom of this underbeam structural arrangement at lift car, the car steel rope is wrapped at the bottom of the sedan-chair on the rope sheave 3, lead boots 6 and engage and can slide thereon with car guide rail in the elevator lifting channel (hoistway), guide the lifting of lift car with this.(two sedan-chair framves found line between beam and the length direction of underbeam body is staggeredly arranged with being separately fixed at two positions of leading boots for the upright beams of two sedan-chair framves, be not on the same straight line), the center-of-gravity position that the underbeam body is arranged in lift car drops at the bottom of two sedan-chairs on the line between rope sheave to guarantee the car center of gravity, and the car center of gravity also drops on the line between the upright beam of two sedan-chair framves, thereby avoided when safety tongs moves car that car guide rail is produced bigger overturning couple, and because the existence of two cant beams 1, increase the bearing surface (becoming 6 supports by 4 traditional supports) between this following girder construction and car, thereby strengthened the stability of car.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the block diagram of the utility model embodiment;
Fig. 2 is the birds-eye view of the utility model embodiment;
Wherein: the 1-cant beam, the 2-safety tongs, rope sheave at the bottom of the 3-sedan-chair, 4-underbeam body, the 5-buffing pad, 6-leads boots, the 7-safety gear block.
The specific embodiment
Fig. 1 has shown a specific embodiment of girder construction under the utility model machine-roomless lift, it comprises the underbeam body 4 of horizontal arrangement, this underbeam body is provided with two safety gear blocks 7, two and leads rope sheave 3 at the bottom of boots 6 and two sedan-chairs, and safety gear block 6 is provided with safety tongs 2.One of them is led boots 6 and is arranged on underbeam body 4 one end right sides, and another is led boots 6 and is arranged on underbeam body 4 other ends left side.Each horizontal welding of the left side of underbeam body 4 and right side is connected to the cant beam 1 of a level, and the end face of these two cant beams 1 is mutually concordant with the end face of underbeam body 4, and cant beam 1 and underbeam body 4 layouts in a certain angle.
With reference to shown in Figure 2, during concrete the application, with the bottom of this underbeam structural arrangement at lift car, the car steel rope is wrapped at the bottom of the sedan-chair on the rope sheave 3, lead boots 6 and engage and can slide thereon with car guide rail in the elevator lifting channel (hoistway), guide the lifting of lift car with this.The upright beams of two sedan-chair framves be separately fixed at two and lead boots 6 places (two sedan-chair framves found line between beam and the length direction of underbeam body is staggeredly arranged, be not on the same straight line), the center-of-gravity position that underbeam body 4 is arranged in lift car drops on the line of 3 of rope sheaves at the bottom of two sedan-chairs to guarantee the car center of gravity, and the car center of gravity also drops on the line between the upright beam of two sedan-chair framves, thereby avoided when safety tongs moves car that car guide rail is produced bigger overturning couple, and because the existence of two cant beams 1, increase the bearing surface (becoming 6 supports by 4 traditional supports) between this following girder construction and car, thereby strengthened the stability of car.In addition, present embodiment is provided with buffing pad 5 at the bottom of described underbeam body 4 midway location.
Certainly, above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow people can understand content of the present utility model and implements according to this, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the spiritual essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
