Description

Drive device for containers buried.

Object of the invention

The present invention is in the field of containers for the collection of urban waste, in which the container itself is kept hidden in a pit under the street plan, that is underground, on a mobile platform capable of adopting two limit positions, a lower one in which the container is integrally housed in the pit, and another upper one in which it is easily removable laterally, accompanying in its movements to the aforementioned loading platform a closing lid, capable of tilting on one of its edges and equipped with the classic mailbox for deposition of waste and drop them to the corresponding
container.

The object of the invention is to achieve a drive device for the mobile elements of the installation that is structurally simple and very solid, with minimal maintenance and with great ease of handling by part of the waste collection staff.

The invention thus falls within the scope of the large capacity waste containers, which by their nature underground they remain hidden in front of pedestrians, improving Urban aesthetics

Background of the invention

For both hygienic and aesthetic reasons, the classic urban waste containers, deposited simply on the street, in areas suitable for that purpose, they go disappearing replaced by underground facilities in which the container or the containers themselves are housed in the sinus dug in the ground and closed by lids, of so that only small mailboxes are visible that, faced with underground containers, allow deposition to through them, from waste, to the bosom of corresponding containers.

In return this type of facilities presents as a fundamental problem the need to have to remove the pit container each time the maneuver is performed of emptying it.

One of the most common solutions consists of provide each container with a loading platform, powered by At least one pair of hydraulic cylinders. This solution so It is only valid for very small capacity containers, since otherwise, during imbalances, imbalances occur between the two hydraulic cylinders, which lead to headers in the loading platform, which can even get blocked by coinage The current solution to this problem is to place under the loading platform a scissor type structure that ensures the horizontality maintenance for the platform, but this solution is structurally complex and consequently expensive, In addition to requiring a notable oversizing of the pit.

Another problem added to this type of container underground is the lid drive, which obviously must be properly synchronized with the movement of the platform. In this sense, installations with two hydraulic cylinders previously mentioned they have transmission systems, based of cables and pulleys, acting on the lid, solution structurally very complex, which requires a high degree of maintenance, since breakdowns are frequent.

Description of the invention

The drive device for containers buried that the invention proposes, belonging to the type of using a pair of hydraulic cylinders, solves fully satisfactory way the problem above exposed, constituting an extremely simple solution and effective, high structural strength and long service life, with a virtually zero maintenance.

To do this and more specifically the device that part of a fixed structure is recommended, destined to stay tightly within the corresponding pit and to which it joins hingedly the complementary top cover, intended to remain flush with the ground and on which the mailbox or mailboxes to the containers themselves, intended to stay within the structure.

To a lower crossbar of said structure, parallel to the hinged line of the lid and noticeably distanced from the imaginary side face of the structure to which the hinges of the lid are associated, a couple of vertical uprights that extend to the vicinity of the lid and that are conveniently in solidarity with the structure by a pair of braces attached to an upper crossbar, being integral to said respective cylinders hydraulics, whose rods displace two arms, which by their upper limb are integral to these stems, and by the lower are related to the uprights by trolleys which facilitate the transmission of efforts to these amounts, said arms acting by their upper extremity on the lid, for tilting it while near its limb Lower receive to container loading platform.

After said loading platform, in space defined between the vertical uprights and the imaginary wall rear of the structure, taking advantage of the empty space that remains under the hinge area of the door, the unit is established electro-hydraulic responsible for operating the hydraulic cylinders for opening and closing the lid, unit controlled by a remote control, held by the driver of the waste collection vehicle.
