Brief description of the drawings
Fig. 1 is the structure diagram of one embodiment of the utility model；
Fig. 2 is beam structure detail view.
Embodiment
The utility model is described in more detail for scheme below in conjunction with the accompanying drawings and preferably.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
Embodiment：As shown in Figs. 1-2, a kind of elevator car rack structure, including top beam 100, bottom girder 300, a pair of of top are consolidated
It is connected in 100 length direction both ends of top beam, the vertical beam 200 that bottom is connected with 300 length direction both ends of bottom girder, it is characterised in that：Sedan-chair
Railway carriage or compartment frame structure further includes extension supporting structure 10 and balanced structure 20 on top beam.
The top beam of car frame except for connect and the vertical beam of the important safety such as safety tongs, cabinet guide shoe outside,
It is the important installation of car top and maintenance place, car top, the especially front side equipped with elevator door, are generally equipped with divulging information
The devices such as fan, a whole set of door-opening mechanism, equipment is more, complex-shaped, and suitable and comfortable position is difficult to find that in installation and maintenance,
Equipment of the i.e. enabled station on front side of corridor maintenance elevator door, it is also difficult to the equipment for getting at elevator door rear portion top beam rear portion.In top beam
It is upper that extension supporting structure 10 is set, the movable space of worker on the top of the car can be effectively extended, easy to worker in car top
Overhauled and safeguarded in each position.Balanced structure 20 can adjust top beam 100 in real time along carriage distribution of weight in the front-back direction, make
The personnel of obtaining keep car frame to subtract together with the weight balancing before and after carriage when operation on top beam 100 or carriage personnel pass in and out
The unequal force of light carriage, maintains the good linear of car frame and guide shoe to coordinate, and increases the running stability of carriage.
Concretely, extension supporting structure 10 is fixed in the middle part of the bottom surface of top beam 100, including arranged on top beam 100 close to electricity
The leading portion 1 of terraced door side, arranged on the back segment 2 away from elevator door side；Back segment 2 and leading portion 1 on 100 length direction of top beam
Vertical median plane is symmetrical, and leading portion 1 is smoothly connected to form whole extension supporting structure 10 with back segment 2.Thus worker can be freely light
Pine gets at the optional position of car roof and from the interference of car top equipment.
Leading portion 1 includes the cross bar 101 parallel to 100 length direction of top beam, the vertical median plane with 100 width of top beam
Two extension rods 102 of symmetrically arranged connection top beam 100 and cross bar 101, connect 101 length direction end of cross bar and top beam
100 brace 103.
Brace 103, top beam 100, cross bar 101, the extension rod 102 of brace corresponding side form reinforcing area, in reinforcing area
For lattice supporting framework.Thus the internal intensity of extension supporting structure 10 is greatly increased, ensures that extension supporting structure 10 will not go out
Existing deformation bending.
Brace 103 is equipped with the inclined support bar 104 being connected with top beam 100.The entirety of increase extension supporting structure 10 and top
The bonding strength of beam 100, as insurance, makes extension supporting structure 10 is overall to be not easily disconnected from top beam 100.
Further, balanced structure 20 includes being arranged on a pair of of driving motor 21 in the middle part of 100 bottom surface of top beam, with driving motor
The coaxially connected screw 22 of 21 output shaft, the pouring weight 23 slid along screw being arranged on screw 22.Two driving motors 21
Output shaft is backwards to setting, and output shaft is symmetrical on the vertical median plane of 100 length direction of top beam.Weight before and after guarantee top beam 100
Amount is consistent, further more, the length along 100 length direction of top beam of pouring weight 23 is consistent with the spacing between two extension rods 102,
Both sides are equipped with guide pad 231；The opposite side of two extension rods 102 is equipped with guide groove 1021, is engaged with the guide pad 231,
So that pouring weight 23 moves under the action of screw 22 along guide groove 1021 in carriage anteroposterior direction, and the characteristics of motion, electrodeless adjustment weight
The orientation of block 23.The back-and-forth motion of pouring weight 23 can be with cooperating personnel on top beam movement, or even human body do not move and only
It is the movement of center of gravity so that the weight before and after carriage keeps balance, mitigates the unequal force of carriage；In carriage normal operation
When, the weight distribution before and after stress and carriage in carriage all changes at any time, and the movement of pouring weight 23 can equally alleviate carriage
Unequal force, maintain the good linear of car frame and guide shoe to coordinate, increase the running stability of carriage, increase usage experience
Good sense.
