Thanks to its electrical operation, the physical presence of more than one operator is not necessary to operate or move said scaffold. It is composed of a rolling structure with four aligned wheels, the rear axle has a drive by means of an electric motor to execute an automatic movement of the scaffold. At the front it has directionally rotating wheels, which makes it easier for the operator to turn the scaffold thanks to a built-in tiller located at a comfortable height for the operator. To make it easier for the operator to get on and off, the scaffold has fixed and removable steps located at the front and rear of the set, with the option of exchanging the removable ones between the rear and front. It also includes headlights, taillights and a beacon to make night work possible.

Sector de la técnicaTechnical sector

Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de equipos, dispositivos y elementos aplicables en la agricultura en general y andamios en particular.This invention has its application within the industry dedicated to the manufacture of equipment, devices and elements applicable in agriculture in general and scaffolding in particular.

Estado de la técnicaState of the art

El uso de andamios no siempre ha estado vinculado a la agricultura. Para el trabajo en alto se utilizaban zancos o escaleras, pero el riesgo de caminar con zancos sobre arena, sumado a la dificultad que conllevaba, permitieron la introducción del andamio para el trabajo en alto de cultivos en invernadero.The use of scaffolding has not always been linked to agriculture. Stilts or ladders were used for work at height, but the risk of walking with stilts on sand, added to the difficulty that it entailed, allowed the introduction of scaffolding for work at a height of greenhouse crops.

Los andamios permiten el trabajo a diferentes alturas, además de cumplir con todas las medidas preventivas para la seguridad del operario en su puesto de trabajo, gracias a las barandas de seguridad. El trabajo es más fácil y rápido, permitiendo el transporte de las herramientas y el fruto con el propio operario.The scaffolds allow work at different heights, in addition to complying with all preventive measures for the safety of the operator in his workplace, thanks to the safety rails. The work is easier and faster, allowing the transport of the tools and the fruit with the operator himself.

Tras la buena aceptación de los andamios manuales, se comienza a introducir los andamios motorizados, compuesto por un motor eléctrico, los cuales permiten al usuario poder desplazarse sin la necesidad de tener que bajar del andamio o de tener que ser empujado por otra persona más.After the good acceptance of manual scaffolds, motorized scaffolds began to be introduced, made up of an electric motor, which allow the user to move without the need to get off the scaffold or have to be pushed by another person.

Descripción de la invenciónDescription of the invention

El andamio motorizado direccional constituye en sí mismo una novedad dentro de su campo de aplicación, ya que facilita el trabajo a diferentes alturas en el interior del invernadero, con lo que se consigue una mejora en las condiciones de trabajo.Directional motorized scaffolding is in itself a novelty within its field of application, since it facilitates work at different heights inside the greenhouse, thereby achieving an improvement in working conditions.

De forma más concreta, está constituido por una estructura rodante con cuatro ruedas alineadas en dos ejes laterales, uno de ellos compuesto por dos horquillas, las cuales permiten el giro de las ruedas delanteras, ya que están unidas a la tija por medio de un sistema de engranajes que acciona el movimiento lateral. La tija está unida al puesto de conducción a través de un timón de dirección. El chasis está constituido de acero y está cubierto por pintura protectora. El eje trasero dispone de un accionamiento por medio de un motor eléctrico para el desplazamiento del andamio, accionando las ruedas directamente a través de un eje de transmisión. More specifically, it is made up of a rolling structure with four wheels aligned on two lateral axes, one of them made up of two forks, which allow the front wheels to turn, as they are attached to the seatpost by means of a system of gears that actuate the lateral movement. The seatpost is attached to the cockpit through a rudder. The chassis is made of steel and is covered by protective paint. The rear axle has a drive by means of an electric motor to move the scaffold, driving the wheels directly through a transmission shaft.

En la parte superior de la estructura se dispone una plataforma de trabajo de altura regulable e incluye también marcos dimensionados para que encajen cajas estándar. Para la subida y bajada de operador se incluye escalera de acceso por la parte delantera y trasera del andamio compuesta por peldaños desmontables y con barandas de seguridad anticaída, regulables en altura, al igual que el timón.At the top of the structure there is a height adjustable work platform and also includes frames sized to fit standard boxes. For the raising and lowering of the operator, an access ladder is included at the front and rear of the scaffold, composed of removable steps and with anti-fall safety rails, adjustable in height, as well as the rudder.

La parte inferior está constituida por un chasis de apoyo y fijación del motor eléctrico, transmisión, fuente de alimentación del accionamiento eléctrico, compuesto por dos baterías, y cuatro ruedas, de la que emergen verticalmente cuatro perfiles en las esquinas que soportan la plataforma de trabajo, de menores dimensiones. Entre los perfiles verticales se disponen unos travesaños móviles que constituyen los peldaños desmontables de unas escaleras de acceso a la plataforma de trabajo. Dichos peldaños constan de un perfeccionamiento caracterizado por la disposición de una armadura tubular metálica en forma paralela y posicionado vertical, con unos peldaños paralelos en sentido horizontal ajustables selectivamente. Los soportes verticales disponen de ranuras en su cara frontal que permiten el acoplamiento de los peldaños móviles, los cuales retienen el giro. Los peldaños se unen a los soportes verticales por medio de dos acoplamientos machihembrado. Tanto el soporte vertical como los peldaños disponen de un orificio en el que se introduce un pasador de seguridad que fija completamente los peldaños al soporte.The lower part is made up of a support and fixing chassis for the electric motor, transmission, power supply for the electric drive, made up of two batteries, and four wheels, from which four profiles emerge vertically at the corners that support the work platform. , smaller in size. Between the vertical profiles there are movable crossbars that constitute the removable steps of some access ladders to the work platform. Said steps consist of a refinement characterized by the arrangement of a metallic tubular frame in parallel and vertically positioned, with selectively adjustable horizontally parallel steps. The vertical supports have grooves on their front face that allow the coupling of the mobile steps, which retain the rotation. The rungs are attached to the vertical supports by means of two tongue and groove couplings. Both the vertical support and the steps have a hole into which a safety pin is inserted, which fully secures the steps to the support.

El andamio además dispone de un mecanismo de frenado y bloqueo de su posición. El motor acciona las ruedas del eje trasero a través de una transmisión. Los mandos de activación del motor y de gobierno de las ruedas direccionales se disponen accesibles desde la plataforma de trabajo, además de un dispositivo de parada. El andamio dispone en la parte frontal de una estructura protectora que la protege contra suciedad y rozaduras.The scaffold also has a braking and locking mechanism. The engine drives the wheels on the rear axle through a transmission. The controls for activating the motor and steering the steering wheels are accessible from the work platform, as well as a stopping device. The scaffold has a protective structure on the front that protects it against dirt and scratches.

Se han incorporado también luces que hace posible el trabajo nocturno situados en la parte frontal y trasera y otra luz rotativa para alcanzar una mayor superficie de iluminación, así como unas luces led en la plataforma de trabajo que ayuda la visibilidad del operario.Lights have also been incorporated that make night work possible located in the front and rear and another rotating light to achieve a greater illumination surface, as well as some LED lights on the work platform that help the visibility of the operator.
