Abstract
The utility model discloses a lifting device of a machine room-free elevator, which comprises two suspension beams (7) arranged at the upper part of an elevator shaft (4) and two cross beams (1) arranged at the bottom of an elevator car (9), wherein a traction machine (3) and a rope head plate (5) are arranged on one suspension beam, a fixed pulley (8) is arranged on the other suspension beam, movable pulleys (10) are arranged at the two ends of each cross beam, the rope head plate (5) is connected with one end of a steel wire rope (2), and the steel wire rope is connected with the traction machine after passing through the movable pulleys on one cross beam, the fixed pulley on the suspension beam and the movable pulleys on the other cross beam. The low-power traction machine can be used to reduce the production cost. The operation of the elevator car is more stable. The lifting device of the machine room-free elevator is particularly suitable for being used in the place with not too many storeys but with strict requirement for running stability instead of running speed of the elevator.
Description
Technical field
The utility model relates to a kind of jacking system of elevator, particularly relates to a kind of jacking system of machine-roomless lift, belongs to the elevator lifting technical field.
Background technology
The jacking system of present elevator, steel rope directly is connected with car roof, the other end of steel rope is connected with the towing machine at the top of elevator, this connection mode, the rising or falling speed of car is fast, but required towing machine power is bigger, and the volume of towing machine is also bigger, has taken installing space bigger in the elevator.
The utility model content
The purpose of this utility model is, a kind of jacking system of machine-roomless lift is provided.Be applicable to elevator speed less demandingly,, can reduce the power and the volume of towing machine, be convenient to be installed in the less machine-roomless lift well in space the place that the elevator running stability is had relatively high expectations.
The technical solution of the utility model: a kind of jacking system of machine-roomless lift comprises two of being located at elevator top hang oneself from a beam and be located at two crossbeams of cars bottom; An overarm is provided with towing machine and rope hitch plate, and another root overarm is provided with fixed pulley; The two ends of two crossbeams are equipped with movable pulley; Rope hitch plate is connected with an end of steel rope, and steel rope is connected with towing machine with movable pulley on another root crossbeam through the movable pulley on the crossbeam, fixed pulley in the overarm.
In the jacking system of aforementioned machine-roomless lift, the spacing between described two crossbeams is greater than half of car width.
In the jacking system of aforementioned machine-roomless lift, described elevator is provided with guide rail, car and guide rail sliding block joint.
Compared with prior art, the utility model is by being installed in two groups of movable pulleys on the car, can make the tractive force of towing machine be decreased to about 1/4th of existing elevator, thereby optionally uses lower-powered towing machine, reduced productive costs.Owing to car with two bigger crossbeam holders of intensity, car plays by four steel ropes, and the operation of car is more steady.It is not many to be particularly suitable for the number of plies, does not need elevator speed too high, but the occasion that the elevator running stability is had relatively high expectations.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-crossbeam, 2-steel rope, 3-towing machine, 4-elevator, 5-rope hitch plate, 6-guide rail, 7-overarm, 8-fixed pulley, 9-car, 10-movable pulley.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.The utility model as shown in Figure 1.A kind of jacking system of machine-roomless lift comprises two overarms 7 that are located at elevator 4 tops and two crossbeams 1 that are located at car 9 bottoms; An overarm 7 is provided with towing machine 3 and rope hitch plate 5, and another root overarm 7 is provided with fixed pulley 8; The two ends of two crossbeams 1 are equipped with movable pulley 10; Rope hitch plate 5 is connected with an end of steel rope 2, and steel rope 2 is connected with towing machine 3 with movable pulley 10 on another root crossbeam 1 through the movable pulley 10 on the crossbeam 1, the fixed pulley 8 of overarm on 7.Spacing between described two crossbeams 1 is greater than half of car 9 width.Described elevator 4 is provided with guide rail 6, car 9 and guide rail 6 sliding block joints.
Principle of work of the present utility model
The utility model is decreased to original 1/4th by two groups of movable pulleys with the pulling force of towing machine.Thereby can select for use power that the towing machine of original power 1/4th is only arranged, and just can meet the demands, reduced the cost of towing machine greatly.Owing to adopt the joist of the higher crossbeam of two intensity as car, strengthen the distance between two crossbeams during installation as far as possible, and movable pulley is installed in the crossbeam two ends, four movable pulleys are symmetrical arranged, by four steel ropes car up-and-down movement that plays, the guide rail sliding block joint of car and elevator both sides makes the operation of car more steady.
