Abstract
Elevator apparatus comprising a control unit comprising a main drive control unit housed in a first container (7) and a main manoeuvre control unit housed in a second container (8), both located outside the elevator shaft (2), wherein said first and second container (7, 8) are separated from each other or in contact so that the surface of a floor projection of both containers (7, 8) does not coincide with the surface of the floor projection of at least one of said containers (7, 8) considered individually. The invention allows to optimise floor efficiency, reducing the impact of the control unit, while a simpler and safer installation and maintenance of the elevator apparatus is achieved.
Description
- The present invention has application in the industry of elevator apparatuses, and more specifically in the field of control units for elevator apparatuses, allowing the optimisation of efficiency on the floor, reducing the impact of the control unit while a simple and safe installation and maintenance of the elevator apparatus is achieved.
- The operation of a elevator apparatus is driven by a control unit that can be considered, broadly, to include a main drive control unit and a main manoeuvre control unit.
- The main drive control unit consists of a set of elements responsible for activating, regulating and controlling the drive unit of the elevator apparatusdevice, which can be electric or hydraulic. In the event that the drive unit is an electric machine, the most important element of the main drive control unit is the speed controller, which controls the rotational speed of the electric machine. In the event that the drive unit is hydraulic, the most important elements are contactors, which control the operation of the pump and the electronic circuit board that controls the hydraulic solenoids.
- For its part, the main manoeuvre control unit consists of a set of elements responsible for the control and the integrated management operation of the elevator apparatus, including aspects such as the movement of the car, lighting, security systems and even the control of the main drive control unit itself. The base element of the main manoeuvre control unit is a central processing unit, CPU for its acronym in English, which is the element in which the computer programming is run and that allows the operating logic of the elevator apparatus.
- Currently, there is a tendency that seeks to optimise the space in a building that is necessary to accommodate the elevator apparatus, maximising the efficiency of the elevator shaft, within which the machine room-less elevator apparatus, MRL by its acronym in English, are encompassed. So, to free up space in the elevator shaft as much as possible, it is attempted to remove from the elevator shaft those fundamental elements of the control unit of the elevator apparatuses which occupy more physical space, among which are included the main drive control unit and the main manoeuvre control unit.
- In the international application No.
WO-02094698-A1 - The fact that the main units of the control unit are installed on the top floor landing makes them easily accessible, allowing for their assembly and maintenance to be performed more comfortably and safely.
- However, according to this solution, the efficiency of the elevator shaft is increased at the expense of penalising the efficiency on the floor level on which said cubicle is found, specifically the last floor level, because the two parts that comprise the cubicle described therein occupy considerable volume and can have excessive dimensions dependant on the space of the landing itself, possibly annoying users of the landing, reducing the free passage area or hindering the manoeuvrability of wheelchairs for users with reduced mobility.
- This problem is more acute in the case of the elevator apparatus being installed in an existing building, in a detached house and even in new construction sites where the project must adapt to a plot of reduced dimensions, i.e., in those cases where the conditions of landing space being available are scarce, so having a single volume of considerable size is an issue and a major impact on the floor level, even hindering access to the elevator apparatus itself from that landing.
- The present invention relates to an elevator apparatus which enables to optimise floor efficiency, reducing the impact on the floor of the control unit of the elevator apparatus, while a simpler and safer installation and maintenance of the elevator apparatus is achieved.
- The elevator apparatus proposed by the invention comprises, at least, one car moveable through a elevator shaft between at least two floor levels served by the elevator apparatus. The car is driven by a drive unit located in the elevator shaft. It is indistinctly contemplated that the drive unit is electric or hydraulic. For its part, each floor level comprises at least one boarding area to said at least one car. Also, the elevator apparatus comprises at least one floor door at each boarding area.
- Boarding areas mean those areas or spaces, located outside the elevator shaft, giving access to the elevator apparatus. It is understood that each boarding area includes the space in the vicinity of a floor door, the ceiling and the adjacent or opposite walls of the room or landing where that floor door is located.
- Also, the elevator apparatus comprises a elevator apparatus control unit, which in turn comprises a main drive control unit, which can control the drive unit, and a main manoeuvre control unit, which can control the operation of the elevator apparatus. An example of an operating sequence is that the main manoeuvre control unit receives an order of movement from the elevator apparatus, manages this information and sends to the main drive control unit the necessary information and travel characteristics according to the order, so that said main drive control unit executes the order, by controlling the operation of the drive unit.
- So, according to the invention, the main drive control unit is housed in a first container located outside the elevator shaft, while the main manoeuvre control unit is housed in a second container, also located outside the elevator shaft. According to the invention, said first and second containers are found alternatively at one of the following two locations outside the elevator shaft. The first alternative is that said first and second containers are separated from each other. The second alternative is that said first and second container are partially in contact so that the surface of a floor projection, i.e. corresponding to a floor of the building, of both containers in contact, that is, the perimeter of the projection of the set of both containers, does not coincide with the surface of the floor projection of at least one of said containers considered individually. That is, the floor projection of both containers will always be different from the floor projection of one of them considered individually.
- Thus, the significant reduction of the impact of a cubicle that occupies a large single volume is achieved, by providing the fundamental elements of the control unit divided into two smaller volumes. In the concept of division and making the most of space is the idea that these smaller volumes occupied by the containers are arranged, either separated, or in the case of being in contact, they are in the manner indicated, so that their impact is less on the floor. In the exemplary embodiments shown in the figures, it will be understood more immediately what the arrangements, according to the invention, involve and their benefits.
- The possibility is contemplated, if the available space so permits, of the said first and second container being located on the same floor level, thus optimising the necessary wiring between the elements of the control unit and facilitating the work of the operator.
- If the available space does not allow it, the possibility of that said first and second container being located in boarding areas located on different floor levels is contemplated.
