Detailed Description

The utility model is further described with reference to the following figures and examples:

the first embodiment is as follows: referring to fig. 1-4, a car elevator comprises a car 2, a tractor 3, a counterweight 4 and a steel wire rope 5, the car is provided with a car door 6, the tractor is mounted on the top of a well through a host mounting beam 7, the car is provided with a car wheel 8, the tractor is provided with a traction wheel 9, the counterweight top is provided with a counterweight wheel 10, one end of the steel wire rope is fixed on a rope hitch plate 11, the other end of the steel wire rope bypasses the car wheel, the traction wheel and the counterweight wheel in sequence and is connected with the rope hitch plate, the counterweight is arranged on the right side of the car, and the counterweight is arranged on the side of the center of the car,

the steel wire ropes are even-numbered, a plurality of groups of traction rope grooves 12 are formed in the traction wheel, and each group of steel wire ropes is wound in one group of traction rope grooves respectively;

a plurality of groups of counterweight rope grooves 13 are formed in each group of counterweight wheels, the number of the counterweight rope grooves is half of that of the traction rope grooves, one half of the steel wire ropes are wound in the counterweight rope grooves of one group of counterweight wheels, and the other half of the steel wire ropes are wound in the counterweight rope grooves of the other group of counterweight wheels;

The front side or the rear side of the car is provided with a car door which is a single door opening mechanism, or the front side and the rear side of the car are respectively provided with a car door which is a through door structure. In the present embodiment, the through door structure is provided with car doors on the front side and the rear side.

In this embodiment, when in actual use, the rotation of traction sheave can drive car and counter weight to remove, and when the car rises, the counter weight descends, and when the counter weight rises, the counter weight descends. In this embodiment, the counterweight is disposed beside the center of the car, and the car door is disposed at the front side and the rear side, wherein the car door can directly adopt a double-side door opening structure, so that the installation of the door machine is not affected by the counterweight. Meanwhile, in the embodiment, two sets of counterweight wheels are adopted, the number of counterweight rope grooves on the counterweight wheels is half of that of traction rope grooves, the number of counterweight rope grooves is less, the width of the counterweight wheels is narrower, the counterweight width can be narrower, the space of a counterweight occupied well is smaller, the space of the well can be occupied by the car is larger, the car with larger size can be manufactured, the carrying capacity of the car can be improved, the utilization rate of the well space is improved, and the cost can be reduced. Simultaneously, the car door structure of foling can adopt the structure that two sides were opened the door, compares with the telescopic mode of opening the door of unilateral, and the speed of opening the door of lift-cabin door is faster, improves user experience.

In the present embodiment, regardless of the through door structure or the one-side door opening mechanism, the occupation of the counterweight on the hoistway space can be reduced, and the utilization rate of the hoistway can be improved.

Referring to fig. 2, the steel wire ropes extend upwards after passing around the car pulleys downwards, pass around the traction sheave and extend downwards between the two groups of counterweight pulleys to be divided into two parts, and one half of the steel wire ropes extend upwards after passing around the counterweight pulleys at the front side and are connected with the rope hitch plate; and the other half of the steel wire ropes downwards bypass the counterweight wheels at the rear side and then upwards extend to be connected with the rope hitch plate.

The traction sheave is arranged above the space between the two groups of counterweight sheaves, and the axis of the traction sheave is perpendicular to the axis of the counterweight sheaves.

The car top wheel is a car top wheel, the car top wheels are two groups and are respectively arranged on the left side and the right side of the top of the car, and the car top wheels are arranged below the side of the traction wheel.

The rope hitch plate is mounted on the main machine mounting beam.

In this embodiment, the car wheel is located above the car center, the traction machine is located above the space between the car and the counterweight, the traction sheave is located above the two counterweight wheels, and the traction sheave is perpendicular to the counterweight wheels, so that the steel wire rope can be smoothly led out from the traction sheave to the two counterweight wheels in half and downwards from the inner sides of the counterweight wheels and then upwards around the outer sides of the corresponding counterweight wheels, and thus the traction sheave synchronously drives the two counterweight wheels to rotate when rotating, and the two counterweight wheels rotate in opposite directions, but can realize the rising and falling of the counterweight. In addition, in the embodiment, the counterweight is arranged in the middle of the hoistway, does not need to be close to the front side or the rear side of the hoistway, gives way to the car door machine, and does not affect the normal opening and closing of the car door. And well space car is more reasonable with arranging to counter weight, and well space utilization maximize, the car can be arranged bigger, improves the load of car. Simultaneously, in sightseeing elevator (transparent glass well), well inner space more need be cherished moreover, more needs beautifully, if say heavily incline in the side of driving sheave, it is not pleasing to the eye enough, link up the not good setting of door moreover. Consequently will to heavily setting up between two parties, to the heavy grooving quantity halving above the counterweight wheel, its width also can reduce a big section, and the width of counterweight wheel reduces, and the width of heavily also can reduce reduces, reduces occupation in space, improves well inner space overall arrangement's rationality, and the aesthetic property is also stronger.

Referring to fig. 2, the rope stopping mechanism includes a middle stopping rope shaft 14, two side stopping rope shafts 15 and a bottom stopping rope shaft 16, the middle stopping rope shaft is disposed between the two sets of counterweight wheels, the two sets of side stopping rope shafts are disposed outside the two sets of counterweight wheels respectively, and the two sets of bottom stopping rope shafts are disposed right below the two sets of counterweight wheels respectively.

The middle gear rope shaft is arranged between the two groups of axle centers of the counterweight wheels, a transverse strip-shaped groove 17 is formed in the counterweight, and the middle of the middle gear rope shaft is installed in the transverse strip-shaped groove in a limiting mode through nuts.

In this embodiment, if the wire rope is loosened, the wire rope may be separated from the counterweight rope groove, and when the wire rope is restored, the wire rope cannot be restored to the counterweight rope groove. Therefore, through setting up the setting of lateral part shelves fag end and bottom shelves fag end, can carry on spacingly with the bottom and the outside of counterweight wheel, well shelves fag end then is used for spacing to the inboard wire rope of counterweight wheel, wherein, distance between two sets of counterweight wheels can be than short, and well shelves fag end then installs and spacing through horizontal bar groove, it is spacing to two sets of inboard wire ropes of counterweight simultaneously to utilize well shelves fag end, from breaking away from in the counterweight rope groove when preventing it from lax, guarantee the security of using. Meanwhile, the arrangement of the transverse strip-shaped groove facilitates the adjustment of the position of the middle rope retaining shaft.
