Description

Underground system for containers urban waste.

Object of the invention

The present invention relates to a system of underground for urban waste containers, whose obvious purpose is to keep underground the containers used in the public roads for the reception of urban waste and allow both the introduction and extraction of those containers for the emptying them in corresponding collection trucks waste.

The object of the invention is to achieve a system that facilitates drive operations for the concealment and removal of the commented receiving containers of urban waste, as well as allowing optimal rationalization as regards the constitution of the set of components that become part of the system.

It is also the object of the invention to provide a system for underground containers with a structuring modular, in order to allow manufacturing the elements and parts of independently and can be assembled later, with the consequent cost savings that implies.

Background of the invention

The new trends on systems underground containers, are based on the standardization of dimensions of the location of the equipment to achieve a fairer competition among manufacturers, in order for a model can easily be replaced by another without having to turn to the previous manufacturer.

Thus, it tends not to establish a unique model that obviously diminishes possible innovations or improvements that other possible manufacturers could bring, tending with it to achieve that all the underground systems to urban waste receiving containers can be replaced for the benefit of users.

Complementarily, the applicant of the present Utility Model is in turn the holder of Utility Models U 200401506, currently granted, and U 200601845, currently in procedure, Models in which a container system is described underground, or what is the same an underground system for urban waste containers, based on the manufacture of a pit on which a structure with a removable part is placed for its elevation and descent, allowing the exit to the outside of the corresponding conventional containers receiving the waste, logically supported in the aforementioned removable part, also including a superior closing platform at the level of the street and carrier of mailboxes for introduction of waste by citizens.

The structure mounted inside the pit includes three racks, one lower and fixed, another located on the above and that constitutes the support for the containers waste receivers, and a third floating upper frame related to the aforementioned, through plates standardized and calibrated, as well as struts with an upper section threaded to allow leveling of this upper frame floating and conditioning to possible slopes of the street in the that the set is implanted.

The lifting and lowering of the removable frame It is formed by four or more hydraulic cylinders, with the rod fixed to the lower and fixed frame, also complementing it with a scissor mounted on the lower frame, whose scissors collaborates in the stabilization during the ascent and descent movements of the platform corresponding to the removable support frame of the waste containers

In addition, in the set referred to has planned that the pit has at its bottom with a chest of registration for water collection, which communicates with another casket external from which the waters are pumped outside.

The commented Utility Models have provided that conventional waste receiving containers have a built-in safety device internally by a probe that is arranged suspended in the inside the container in which it is applied, so that probe when pushed into the filling by waste, change position and set the activation of a closure electromechanical or of any other nature that prevents opening the lid of the respective access box inside the container of which try, that is, the one that approximates its filling.

Description of the invention

The system that is recommended, based on the characteristics referred to above, presents a series of particularities that on the one hand consist of reducing the time stay outside the usual workplace, where it is more A unfortunate accident is likely to occur.

In addition, the system of the invention presents as one of its fundamental characteristics is the fact that part of Its construction is modular, allowing manufacturing more comfortable and faster and making it possible to do a series job, whose pieces will be assembled in a final phase, getting with this an increase in performance and decrease of costs, in addition to have the possibility to vary the configuration of the whole system and avoiding having to vary the production and realization, to supply potential users, that they need for any circumstance another container model.

Also, the system of the invention has been designed to improve the environmental impact, getting a adaptation with great ease to a possible setback that may cause the ground, having a greater possibility of installing the set.

The aforementioned benefits and advantages are they get based on particular structural characteristics of the system, where the main structure is formed by six tubular profiles on the front that act as elements carriers, and in combination with four "L" profiles that they occupy the four corners, the latter being reinforced with other profiles similar to those located in the central part of the structure.

The "L" profiles in addition to protecting four hydraulic pistons located in the corners as elements of elevation and descent of the main structure, determine also a support of said structure.

Based on the layout of the four pistons hydraulic, the upper frame of the structure is suppressed provided in the utility models referred to as background, as well as the guide scissors for lifting it, achieving several objectives, including reducing weight, simplifying construction and increase outside services, improving with it works in series of that type and getting better yields in production.

Another feature of the novelty of system of the invention is that the upper part of the main structure, where inboxes are located of the waste bags, it is floating and extensible in both directions, that is in the longitudinal direction and in the direction transverse, said floating structure acting as the cover of the Principal structure.

That extensibility of the floating structure allows to assume the extension of its dimensions in the unevenness of the land, without the need for reforms in the structure that would be A big problem, "in the field."

The main and floating structures are joined together by screws, supporting the floating structure in the main one, so that the screws are through of holes provided in the floating structure, tapping by its other end in nuts provided in the main structure, of so that the clearance between both structures will be less than 10 mm, so passing a sufficient number of screws both will remain fully fixed supporting the work entirely by the Principal structure.

In case of the land situation there was an unevenness, the two structures would be different dimension, so that to solve this problem, a additional element consisting of a plate, manufactured and workshop calibrated that joins the two structures with screws as the aforementioned, supporting those plates in the Principal structure.

As for the floating structure, it can be said that it includes a particular piece, as a cap that is arranged concentrically inside the profiles main, and adjusted to these, to establish the means of telescopicity and therefore of extensibility of said structure floating.

The leveling of the floating structure with the terrain will be done quickly and easily, so the Risk for field personnel is minimal, as well as machinery necessary to develop it.

Finally, say that inside the underground set will be made by means of a simple "cat hydraulic "to raise the floating structure to a level of land that must be reached both longitudinally as transverse, so that the next operation to this process consists of fixing the plates to the two structures, main and floating, so that with a minimum number of plates the union between both structures is achieved in a way monolithic and rigid, leaving the set as unique structure.

Preferred Embodiment of the Invention

In view of the referred figures, and doing reference specifically to figures 1 to 4, the system of invention corresponds to an underground system of a structure general (1) of containers (2) on a pit (3) made at effect on the ground, and whose main structure (1) defines four sectors where so many other containers are positioned (2), determined that a lower support (1 ') for the different containers (2) intended to receive bags with waste urban, being buried those containers (2) because the general and main structure (1) is housed inside of the pit made on the ground.

Well, from these characteristics, It should be noted that this main structure (1) is specifically formed by six tubular profiles in combination with four "L" profiles (4) located in correspondence with the corners, which in turn constitute means of protection for respective cylinders or hydraulic pistons (5) located precisely in those corners and planned to carry out the rise and fall of the main structure (1) and therefore of the containers (2), so that they are flush with the ground as depicted in figures 2 and 4, or buried as represented in figures 1 and 3.

Said main structure (1) is complemented with a floating and superior structure (6) that besides acting as the lid of that is equipped with the corresponding openings or mailboxes for depositing bags with urban waste that they must fall into the containers (2).

According to another of the characteristics of the invention, the floating and upper structure (6) has a profile configuration in "Z" as far as the support profile is refers, since the plate that constitutes the closing cover of the floating structure is a rectangular plate that is supported precisely in the "Z" profile as clearly shown in Figure 9, that profile of the floating structure (6) being affected holes (7) for passage of corresponding screws (8) fixing said structure.

The pistons (5) provided in the corners they serve to raise the main structure (1) with its platform of base (1 ') of support of the containers (2), to be able to place these at ground level, as depicted in figures 2 and 4, and can be loaded and unloaded by a municipal vehicle of garbage collection, leaving those hydraulic pistons (5), as It has also been said before, protected by profiles in "L" (4) provided in the corners as a complement to the main structure profiles (1).

In figure 9 you can clearly see the holes (7) of the floating structure (6), specifically of its support profile, facing other holes (7 ') provided for effect on the profile of the main structure (1), for location of the fixing screws (8), with the particularity that the Threading of these screws is made on a nut (9) provided precisely in the main structure (1).

The lower corner is shown in figure 8 where the corner profile (4) is logically protecting the hydraulic piston (5).

As for the floating and superior structure (6), the same, as shown in Figure 7, is modular and is constituted by a square profile (11) whose two wings define two tubular sections (11 ') in which two are connected bushings or special parts (12) in which they fit, also by plug, a second modular part (13) of the same structure floating, looking at that figure 7 as the slack (14) is the length you have to increase the structure to reach a higher level than the main structure, so that with This system can reach levels higher than 15%, while that the clearance (14 ') is the one that should be increased transversely to the floating structure to achieve liberation in said sense, even being far inferior to the slack (14).

Finally, it should be noted that, in case of unevenness, the union between the main structure (1) and the floating structure (6), those shown in figure 10, is performed with the collaboration of some plates (15) with holes (16) to pitch of the fixing screws (8), as in the previous case, plate (15) that rests precisely on the structure main (1) as shown in figure 10, and where Screw nuts (9) for fixing screws (8), are located on the outer face of such a plate (15) and logically in the external face of the main structure (1), as also seen clearly in the commented figure 10. It also shows also as the "Z" profile of the floating structure (6) it is capable of being finished off by its edge in an element of tightness (16) conveniently fixed.
