Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1 and 3, the arrangement of the original machine room-less elevator (i.e. before the modernization of the machine room-less elevator) is such that the hoisting machine 20 and its traction sheave 21 are mounted on the shaft pit 12, both in the lowest position of the ground of the elevator shaft 10. Once a rainstorm and flood problem occurs, the rainwater continuously flowing into the hoistway pit 12 will inevitably submerge the traction machine 20 gradually, causing damage of the traction machine 20 due to water soaking, high maintenance cost, and meanwhile, the elevator without a machine room can not operate normally within a long period of time, causing the trouble that passengers do not have a ladder for use.

As shown in fig. 2, it can be seen from the structural diagram of the overhead view of the conventional elevator without machine room that the size of the conventional hoisting machine 20 mounted on the hoistway pit 12 is large, and the projection in the horizontal direction overlaps with the projection of the car 30 in a large area, which means that there is a risk of collision and interference with the hoisting machine 20 when the car 30 moves downward, and the operational reliability of the elevator without machine room is affected to some extent.

Aiming at the hidden danger of water soaking of the traction machine 20 and the hidden danger of collision interference between the lift car 30 and the traction machine, the application provides a new transformation scheme of the elevator without the machine room, namely a new arrangement structure of the elevator without the machine room.

Continuing to refer to fig. 4, a new machine room-less elevator arrangement is presented for an embodiment of the present application, the machine room-less motor arrangement comprising: an elevator hoistway 10, a traction machine 20, a car 30, a sheave assembly 50, and a counterweight 40.

The elevator shaft 10 is provided with a lowest landing 11 and a shaft pit 12, and the lowest landing 11 is positioned above the shaft pit 12; the hoisting machine 20 is provided on a side wall of the elevator shaft 10, and the hoisting machine 20 is located at a position higher than the height of the lowest landing 11; the sheave assembly 50 is installed in the elevator shaft 10 and is drivingly connected to the hoisting machine 20, and the car 30 and the counterweight 40 are movably connected to the sheave assembly 50 and can move up and down in the elevator shaft 10.

In summary, the implementation of the technical solution of the present embodiment has the following beneficial effects: the arrangement structure of the machine room-less elevator in the scheme substantially relates to the structural improvement of the machine room-less elevator, and particularly compared with the traditional machine room-less elevator in which the traction machine 20 is arranged in the pit of the elevator shaft 10, the arrangement structure of the machine room-less elevator realizes that only the new traction machine 20 and the new arrangement position thereof need to be replaced when the machine room-less elevator is improved, and the original elevator components of the machine room-less elevator can be kept to continue to be the use effect of the new machine room-less elevator. Specifically, when in modification, a new hoisting machine 20 is installed on a side wall of the elevator shaft 10, the rope pulley assembly 50 is installed in the elevator shaft 10 and is in driving connection with the hoisting machine 20, and finally the car 30 and the counterweight 40 are respectively movably connected with the rope pulley assembly 50, so that the car 3 and the counterweight 40 can move up and down in the elevator shaft 10 under the condition that the hoisting machine 20 outputs power, namely, the normal operation of the newly modified machine room-less elevator is realized. Because the new traction machine 20 is installed at a position above the height of the lowest landing 11 of the elevator shaft 10, and the lowest landing 11 is located above the shaft pit 12, even if rainstorm weather occurs, rainwater leaks into the shaft pit 12, rainwater is accumulated and can only rise to the floor height position of the lowest landing 11, rainwater cannot contact the traction machine 20 above the immersed traction machine, the traction machine 20 cannot be soaked by rainwater, safe and reliable operation can be ensured all the time, maintenance cost caused by damage of water bubbles can be avoided, and normal operation of the elevator without a machine room can be ensured.

It is easy to understand that the above-mentioned car 30 and its car frame, rope sheave assembly 50, counter weight 40 and its counter weight 40 frame and the elevator components such as the guide rail installed in the elevator shaft 10 are affiliated to the original elevator without machine room, adopt the technical scheme of this embodiment to the mounted position optimization adjustment of hauler 20 after, above-mentioned each elevator component can remain and continue to be used by new elevator without machine room, so can reduce the transformation cost by a wide margin, be favorable to resource cyclic utilization and avoid extravagant. Of course, it should be noted that, in the actual construction and modification operation, if it is estimated that some original elevator components cannot be used continuously due to serious wear and the like, the elevator components can be replaced by new ones.

On the basis of the above embodiment, the arrangement structure of the machine room-less elevator further includes a mounting seat provided on a side wall of the elevator hoistway 10, on which the traction machine 20 is provided. The traction machine 20 can be stably mounted on the sidewall of the elevator shaft 10 by the mount.

However, it should be noted that the hoisting machine 20 is directly mounted on the sidewall of the elevator shaft 10 or is mounted and fixed on the sidewall of the elevator shaft 10 by a mounting base, and may be selected according to actual reconstruction needs, and is not particularly limited herein.

Further, on the basis of the above embodiment, the mounting seat includes a seat body and a damping block, the seat body is provided with a sliding groove, the sliding groove extends in a direction perpendicular to the hoistway pit 12, the damping block is slidably disposed in the sliding groove and can be fixed in the sliding groove, and the traction machine 20 is disposed on the damping block. After the initial installation, the traction machine 20 can slide up and down in the sliding groove by means of the damping block, so that a more accurate height position can be obtained. Particularly, after a dangerous case that rainwater flows into the hoistway pit 12 once occurs, the sliding adjustable mounting structure can adjust the position of the traction machine 20 according to the dangerous case, so that the traction machine 20 is far away from flooding as far as possible, and the traction machine 20 can work safely and reliably.

In order to further fix the traction machine 20, after the traction machine 20 is adjusted to a proper position, the traction machine 20 and the seat body can be assembled and fixed by screwing, buckling, hooping or other mounting methods with equivalent technical effects.

With continuing reference to fig. 4, in further embodiments, the mounting base further includes a water deflector 60, the water deflector 60 is disposed on the base body and below the traction machine 20, and the water deflector 60 separates the traction machine 20 from the hoistway pit 12. The splash plate 60 disposed below the machine 20 can form a barrier to further prevent the flooded water in the hoistway pit 12 from contacting the machine 20.

Referring to fig. 4, specifically, the water baffle 60 includes a plate body and a bending plate disposed on the plate body, and the bending plate is bent in a direction away from the hoistway pit 12. The water baffle 60 and the seat body are integrally assembled and connected through the plate body, and the connection strength is high. The bending plate bending upwards in the direction away from the hoistway pit 12 can surround the traction machine 20 and form an effect similar to a weir wall, so that even if too much rainwater is accumulated in the hoistway pit 12, the rainwater can be blocked by the bending plate after the rainwater surface is submerged in the floor of the lowest landing 11, and the rainwater cannot contact the traction machine 20 even if the height of the rainwater is close to the traction machine 20 at the moment, so that the safety of the traction machine 20 is ensured to the maximum extent.

With continued reference to fig. 6, in addition to any of the above embodiments, the projection of the hoisting machine 20 on the hoistway pit 12 does not coincide with the projection of the car 30 on the hoistway pit 12. That is, the traction machine 20 adopts a thin design, occupies a small space in the hoistway, and forms a safety gap with the outer wall of the car 30 after being mounted on the side wall of the elevator hoistway 10, thereby effectively preventing the car 30 from colliding and interfering with the traction machine 20 during the lifting operation.

Further, referring to fig. 5, when viewed from above the elevator shaft 10, the position of the traction sheave of the hoisting machine 20 is the same as or close to the position of the traction sheave of the old hoisting machine 20 originally installed in the shaft pit 12 in the projection direction. Therefore, the transformation construction difficulty can be reduced to a great extent, and the original elevator components do not need to be changed and adjusted.
