Description

SUPPORT PEDESTAL FOR AERIAL BASKET LIFTING ASSEMBLY APPLIED TO VEHICLE CHASSIS FIELD OF INVENTION

[0001] In general, the present invention belongs to the technological sector of equipment for working at height and refers, more specifically, to a new constructive design applied to a support pedestal for an aerial basket lifting assembly with an integrated hydraulic reservoir, used, for example, by electricity concessionaires for work on distribution poles, which is a structural component connecting the lifting assembly and the vehicle's subframe, with a conical shape, which allows the lifting assembly to rotate in relation to the truck, so that the integration of the hydraulic reservoir reduces the risk of damage to the equipment caused by collisions or external contamination. BACKGROUND OF THE INVENTION

[0002] Currently, the formats adopted for the production of support bases for aerial basket lifting assemblies applied to state-of-the-art trucks feature heavy geometry, with high demands on welded joints and, consequently, more susceptible to structural failure problems.

[0003] An example of a problem that occurs in currently known technologies is the rupture of welds at specific stress points, since the stresses are distributed unevenly, causing only some points of these pedestals to be attacked.

[0004] In this sense, as an example of the technical problem highlighted above, document EP3157856 (Socage. 2017) can be observed, which discloses a support structure that has a coupling assembly suitable for rotating support devices, with the various stabilizers being able to be extended and retracted along a respective extension axis, with the stabilizers being arranged next to a lateral surface of the axes of the extension coupling assembly that do not intersect with the lateral surface and with the stabilizers being arranged tangentially to the lateral surface of the coupling assembly.

[0005] It should be noted that the aforementioned document presents a welded structure provided by four bars perpendicular to each other, so that the stresses in the pedestal are distributed unevenly across the base, posing a risk of rupture, as per the technical problem previously pointed out. Furthermore, the hydraulic system is not integrated, posing the risk of damage due to collisions and external contamination previously described.

[0006] There is also document US20200002955 (Time Mfg. 2020), which describes an apparatus that has multiple hoses that are routed through an isolation element attached to an aerial work platform. A fluid tank is attached to the aerial work platform. The fluid tank is disposed in a lower portion of a hydraulic aerial lift that is electrically connected to the ground. The manifold includes a first face and a second face such that multiple through ports extend from the first face to the second face to allow fluid to flow through multiple hoses. Multiple hoses extend from the first face of the manifold. Multiple hoses extend from the second face of the manifold. collector face. The isolation element isolates the aerial work platform from the fluid tank and all electrically connected sources arranged at the bottom of the hydraulic aerial lift that are electrically connected to the ground. The material is selected from the group consisting of plastic, ceramic and glass.

[0007] Similar to the first previous point, the tensions in this pedestal are distributed across the base in a non-uniform manner, posing a risk of rupture, as per the technical problem previously mentioned.

[0008] Therefore, based on all the drawbacks existing in the systems and equipment currently used, described above in the state of the art, it is clear that there is a gap in the creation of a new construction arrangement applied to a support pedestal for an aerial basket lifting assembly with an integrated hydraulic reservoir, used, for example, by electricity concessionaires for work on distribution poles, which is a structural component connecting the lifting assembly and the truck subframe, with a conical shape, which allows the lifting assembly to rotate in relation to the truck, so that the integration of the hydraulic reservoir reduces the risk of damage to the equipment caused by collisions or external contamination. SUMMARY AND OBJECTIVES OF THE INVENTION

[0009] As it is a component that is subjected to high levels of mechanical stress, the invention proposed herein presents a pedestal with a conical geometric shape and a circular base.

[0010] Mechanical stresses are better distributed in the conical geometric shape with a circular base when compared to the cylindrical or conical shape with a square base, for example. Therefore, the The pedestal now revealed presents a larger support point in relation to the state of the art.

[0011] This geometric shape allows mechanical stresses to be better distributed throughout the component, ensuring greater operational safety.

[0012] Its simple assembly method, using welding, allows it to be mass produced, with the side plates being bent in a specific way, forming a cone from 5 side faces divided between the side plate on the right and left sides.

[0013] Another important detail is the insertion of an integrated oil reservoir inside the pedestal. This is only possible because the pedestal has a conical shape, which allows the installation of a reservoir with the ideal amount of oil for platform operation.

[0014] Finally, with the aim of remedying the shortcomings of the current state of the art highlighted above, the present invention aims to propose a solution for a support pedestal for an aerial basket lifting assembly with an integrated hydraulic reservoir, used, for example, by electricity concessionaires for work on distribution poles, which is a structural component connecting the lifting assembly and the vehicle's subframe, with a conical shape, which allows the lifting assembly to rotate in relation to the vehicle, so that the integration of the hydraulic reservoir reduces the risk of damage to the equipment caused by collisions or external contamination.

[0018] Figure 3 shows an exploded view of the support pedestal.

[0021] The pedestal (1) now revealed is composed of a lower plate (2) responsible for securing the pedestal (1) to the vehicle chassis (not shown), an oil tank (3) integrated inside the pedestal (1) equipped with an oil filter (15), a hydraulic valve (4) responsible for promoting the flow of hydraulic fluid inside the pipe (14) and an emergency hydraulic pump (5) to enable hydraulic flow in the event of a breakdown, an inspection cover (6) responsible for allowing the evaluation of the assembly with regard to parameters such as the condition of the pipe (14), among others.

[0022] An upper plate (9) stabilizes the upper portion of the pedestal (1) and receives the hydraulically controlled turning module (8), which enables the rotation of the lifting assembly (16) and the aerial basket (16A).

[0023] The dimensions of the lower plate (2) must comply with the width of the vehicle chassis and the dimensions of the upper plate (9) with turning module (8) are standardized according to the supplier.

[0024] The pedestal (1) equipped with a lower plate (2) and an upper plate (9) with a turning module (8) allows the formation of a conical structure formed from 5 lateral faces.

[0025] The pedestal (1) now revealed has a set of left (7) and right (10) side plates, whose folds form a cone formed from 5 faces, giving the conical structure with a round base described now.

[0026] The format that best suited this upper dimension (plate (9) and turning module (8)) and lower dimension (plate (2)) and at the same time was easy to manufacture, was the format with 12 faces (Dodecahedron). Thus, the pedestal (1) now revealed in the set of Figures, has a set of left (7) and right (10) side plates, whose folds form a cone with a total of 12 faces (dodecahedron), with the right side plate (10) having seven faces and the left side plate (7) having five faces, in order to provide the conical structure with a round base now described.

[0027] It should be noted that the construction of the pedestal (1) in a conical shape can be formed from 5 (five) side faces divided between the left (7) and right (10) side plates.

[0028] Finally, it has an hour meter (1 1 ), in order to allow the control of the engine's operating time for carrying out preventive maintenance, and an oil level display (13), being equipped with a filler cap (12) designed to allow the insertion of oil into the tank (3).

[0029] In other construction modalities, the pedestal (1) may form the conical structure together with the plate (2) and plate (9) through faces that may vary between 5 and 14, as represented in the set of Figures 5 to 5H.
