Description
Technical Field
The invention belongs to the technical field of elevator traction machines, and particularly relates to a permanent magnet explosion-proof safety-increased machine room-free overhead traction machine.
Background
As is known in the art, there are some of the machine room-less traction machines, the former in which a traction machine is disposed at the top of a hoistway, i.e., on a traction machine supporting cross member (also referred to as a "hoistway top cross member") corresponding to the upper side of a car, and the latter in which a traction machine is disposed at the bottom of a hoistway, i.e., in a foundation or pit of a hoistway corresponding to the lower side of a car. Since the merits of the two methods are well known in the art, they are not described in detail.
The typical example of the permanent magnet explosion-proof safety-increasing type tractor without the machine room mentioned above can be referred to "a permanent magnet explosion-proof safety-increasing type tractor" recommended by CN207108196U, which is proposed for the tractor to have explosion-proof performance, and specific technical contents and technical effects can be referred to in paragraphs 0004 to 0012 of the specification of CN 207108196U.
The permanent magnet explosion-proof safety-increased type machine room-free overhead type tractor in the prior art comprising the CN207108196U has the following disadvantages: for one, since it is influenced by the conventional design concept and the control box (also called "controller junction box or even controller") is arranged on the upper part of the brake in order to comply with the macroscopic continuity of the technical structure, the design is not good in form and has never seen any doubtful technical information for the structural design for a long time. However, since the machine without machine room has a relatively strict design rule for the height of the hoistway as its service environment, in order to find a balance point between the height of the hoistway and the installation of the hoisting machine, a space between the control box and the top of the hoistway is reserved to be about 40cm, which is mainly used for the inspection and maintenance of the hoisting machine by the inspection and maintenance personnel. Apparently, the space of 40cm can basically meet the requirement of the inspection operation, but the condition that the head and the body of the inspection personnel possibly need to be inserted into and correspond to the upper part of the control box in the inspection process is not considered, so the reserved space of 40cm cannot meet the actual space requirement of the inspection operation in most cases. Of course, if the hoistway height is increased to increase the adaptability of the reserved space, although the inspection and maintenance work can be facilitated, the requirement of the design specification of the hoistway height is violated, and thus the method is not preferable; secondly, as known in the art, when all parts of the hoisting machine including the control box, such as the brake and the hoisting machine body, are overhauled, the power supply is temporarily cut off when the power supply is cut off, and the elevator car is required to be gradually lifted to the upper part of the hoistway with the help of a counterweight, so that the inspection and maintenance personnel can reach the part of the hoisting machine at the top of the hoistway from the top wall of the elevator car with the help of a ladder or a similar climbing tool, and the elevator car must be always kept at the upper part of the hoistway as long as the operation of the inspection and maintenance personnel is not completed, however, the measures for satisfying the above requirements are not suggested in the patent and non-patent documents which are published so far; thirdly, since the traction machine body is fixed to a steel chassis (CN 207108196U, this patent is called "steel chassis"), which has a relatively large height, the total height of the whole traction machine is also increased to some extent, the effective stroke is reduced and the above-mentioned reserved space is occupied to some extent, that is, if the height of the steel chassis can be reasonably reduced under the premise of ensuring the strength for supporting the traction machine, the saved space can be sponsored and allocated to the upper reserved space to play the role of one arrow multiple carving.
