Preferably, the forced driving main machine is located on the outer side of the bottom of the hoistway, a through hole is formed in the position, corresponding to the forced driving main machine, of the hoistway, and the rope guide penetrates through the through hole and then extends into the hoistway.
Preferably, the projection of the two return rope wheels in the vertical direction is positioned outside the projection of the elevator car in the vertical direction.
Preferably, the two rope return wheels are respectively installed on the two bottom supports, the car bottom rope return wheel can freely rotate around the axial lead of the car bottom rope return wheel, and the two bottom supports are respectively and fixedly connected with the bottom of the elevator car.
Preferably, the guide wheel is mounted on the top of the hoistway through a top bracket, and the guide wheel can freely rotate around the axis line of the guide wheel.
Compared with the prior art, the utility model has the advantages of as follows:
1. the utility model discloses a force the driving host computer for vertical, can effectively practice thrift the well space with forcing the setting of driving host computer in the elevator well outside to satisfy different customers' design demand.
2. The utility model discloses utilize the pulley combination of fixed pulley and movable pulley to reach laborsaving effect, make the driving host computer can pull up heavier object under the condition of equal pulling force, also promoted the bearing capacity of elevator.
3. The utility model discloses can also effectively reduce the occupation to well headspace, promote the clear height at elevator car top, reduce the oppression sense that the space brought.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic structural diagram of another embodiment of the present invention.
In the figure: the elevator car forced driving device comprises a forced driving main machine 1, a steel wire rope 2, an elevator car 3, a guide wheel 4, a rope return wheel 5 and a rope head assembly 6.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example (b): the utility model provides a novel force driven elevator, includes well, car guide, force drive host computer 1, leading wheel, wire rope 2, elevator car 3, at the relative both sides of well vertical car guide that is equipped with respectively, car guide is fixed mutually with the well, elevator car links to each other with car guide sliding fit, its characterized in that, force the drive host computer and be located the well outside, it is around the vertical setting of rope sheave. The guide wheels 4 are arranged at the top of the hoistway, two sets of car bottom rope return wheels 5 are arranged at the car bottom of the elevator car, and a rope head assembly is arranged at the upper end of the car guide rail at one side far away from the driving host machine, wherein the guide wheels, the rope return wheels and the rope head assembly are positioned on the same vertical plane; the steel wire rope is wound on the rope winding wheel of the forced driving main machine, one end of the steel wire rope is fixedly connected with the rope winding wheel, the other end of the steel wire rope firstly winds the guide wheel and then extends downwards, and the steel wire rope winds the two groups of car bottom rope return wheels at the car bottom and then extends upwards and is fixedly connected with the rope head assembly 6. The guide wheel and the return rope wheel are matched for use, so that heavier objects can be pulled under the condition of the same tension of the forced driving main machine, and the carrying capacity of the elevator car is improved.
When the elevator car is specifically implemented, the forced driving main machine 1 is provided with a rope guide, the steel wire rope can be guided to one side of the guide wheel, which deviates from the car, through the rope guide, namely the change of the leading-out direction of the steel wire rope is realized by utilizing the rope guide, so that the steel wire rope can conveniently bypass the guide wheel.
In one embodiment, referring to fig. 1, the main force-driven machine is located outside the top of the hoistway, the rope winding wheel and the guide wheel are located on the same plane, and the steel wire rope is led out through the rope guide, extends towards the direction of the guide wheel, winds around the guide wheel, and then extends downwards to wind around the rope return wheel.
In one embodiment, referring to fig. 2, the forced driving main machine is located outside the bottom of the hoistway, a through hole is formed in the hoistway at a position corresponding to the forced driving main machine, and the rope guide penetrates through the through hole and then extends into the hoistway.
The utility model discloses can install the forced drive host computer in the different position in the well outside to satisfy customer's design needs, simultaneously, will force the drive host computer setting outside the well, can also save the well space, be applicable to the elevator installation of family.
When the elevator car is specifically implemented, the projections of the two return rope wheels in the vertical direction are positioned outside the projections of the elevator car in the vertical direction, so that the steel wire rope is prevented from being in direct contact with the elevator car. The two rope returning wheels are respectively arranged on the two bottom supports, the rope returning wheel at the bottom of the elevator car can freely rotate around the axial lead of the rope returning wheel, and the two bottom supports are respectively fixedly connected with the bottom of the elevator car. The guide wheel is installed at the top of the well through a top support, and the guide wheel can freely rotate around the axis line of the guide wheel.
The present invention is not limited to the above embodiments, and the same or similar structures as those of the above embodiments of the present invention are all within the protection scope of the present invention.
