Abstract

Visual control device for excavators

Constituted by a united television camera jointly and severally by means of adequate connection to one of the segments that make up the articulated arm of the excavator and focused directly over the concave area of the shovel, so that the focus from the camera collect the image of the shovel and its surroundings. This camera television is conveniently protected by a grid that prevents you from hitting fragment of stones, sand or products typical of the excavation.

The television camera is connected by cable to a television monitor located in a convenient place inside the excavator cabin.

Description

Visual control device for excavators

The present invention relates to a device that by installing a camera television and a monitor allows the driver of an excavator to have exact control of shovel movements, eliminating Dangerous situations when the operator sees the exact place where he should dig or unload the removed earth.

It has its field of application in the industry of construction and uniquely in the movement industry of land and more specifically in the auxiliary industry of excavators and backhoes

In this sector of the technique, those prevail effective developments and specifically dedicated to the function in question, that give rise to a system of simple installation, with Low cost and technically appreciable results. The System features presented in this invention are adapted perfectly to this concept, offering the state of the art a novel, simple, simple and manufacturing embodiment highly economical

They know each other in this industry sector Some models that do not contribute to the state of the art novel features proposed by the present invention. Thus, the Document ES 2 103 396 T3, proposes to control the surface of a ditch by means of a cable and a swivel arm, which although the operator can measure the performance of the blade with acceptable accuracy over the ditch, you cannot directly see the work that is doing.

The lack in the state of the art of a method as proposed by this invention, presents the following inconveniences:

In innumerable occasions when the operator you must dig wells or ditches, you have to do it without any kind of visual control, being forced to descend from the cabin to Check job status. Sometimes it must be helped by another operator located dangerously close to the performance of the shovel. When loading trucks, the operator cannot see with accuracy the situation of the bat, causing shovel shock against the truck, dangerous situations for the assistant and spill out of the bat of the product to load. It's normal that in all these constructions there are embankments and slopes that they place the excavator in work angles that make it impossible A good view from the cockpit of the performance area. The dedication of assistants who direct the maneuvers, increases the labor cost

The fact of working with poor visibility, obliges the operator to devote more time to his task.

Given these inconveniences described, the present The invention brings innovative solutions to the state of the art, simple and easy to execute that result in the following advantages:

When the operator must dig wells or ditches, he does it with perfect visual control, not being forced to get off the cabin to check the work status. Do not It has to be helped by another operator, avoiding situations of danger. When loading trucks, the operator can see with accuracy the situation of the bat, thus avoiding clash of the shovel against the truck, dangerous situations for the assistant and spill out of the bat of the product to load.

Before the existence of embankments and slopes that place the excavator in difficult work angles, always The driver will have a good view, from the cabin, of the area of acting. The collaboration of helpers is not necessary, thus reducing the cost of work. The fact of working with better visibility, the operator dedicates less time to his task.

All these conjugated elements give rise to a final result in which differentiating characteristics are provided significant compared to the state of the art.

Thus, the invention is constituted from the following elements: A television camera united in solidarity by means of adequate connection to one of the segments that make up the articulated arm of the excavator and focused directly on the concave area of the shovel, so that the camera's focus picks up The image of the shovel and its surroundings. This television camera is conveniently protected by a grid that prevents you from being hit fragments of stones, sand or products of the excavation.

The television camera is connected by cable to a television monitor located in a convenient place inside the excavator cabin.

In a different embodiment the chamber of Television is provided with zoom.

Differently the television camera is adjustable.

Another different embodiment incorporates several television cameras conveniently located on the sides and front of the articulated arm.

Regardless of the connection between the camera and the Monitor is wireless.

The camera protector differently It is made of glass or transparent plastic.

In another different embodiment the chamber of television is embedded in a hole practiced in a segment of the articulated arm.

For better compression of this memory descriptive, a drawing is attached that by way of example does not limiting describes a preferred embodiment of the invention.
