Arrangement introduced in railway post with old-time lifting and locking mechanism for linear movement of solar panel elevator and related equipment

Description

[001] This utility model relates to an arrangement introduced in a railway pole with a lifting and anti-fall locking mechanism for the linear movement of a solar panel elevator and related equipment, such as surveillance cameras, luminaires, batteries, among others. Said railway pole presents innovative characteristics by being equipped with a lifting mechanism composed of an actuating crank connected to a steel cable responsible for promoting the upward or downward movement of a linear carriage that slides vertically in relation to the pole's axis, this carriage being the support for the solar panel and other devices.To ensure the safety of the assembly, said linear carriage incorporates two locking mechanisms, namely: (i) locking the carriage in an elevated position to prevent unwanted movement; (ii) a safety device activated in case of breakage of the steel cable to brake the carriage by friction, preventing a sudden fall and, consequently, preventing damage to the attached equipment, as well as reducing the risk of vandalism. HISTORY OF THE TECHNIQUE

[002] It is known that railway poles are vertical structures strategically positioned along railway lines, designed to optimize the use of space adjacent to the railway infrastructure. Their primary function includes the installation of photovoltaic panels, aimed at generating solar energy for various applications such as powering the derailment detection circuit, among others, as well as providing support for other complementary equipment such as, for example, camera surveillance systems, lighting devices and energy storage units.

[003] Currently, two predominant models of poles for the secure mounting of solar panels and their respective equipment compartments are identified. The first model, called a fixed pole, is characterized by the use of segments Petition 870260036303, dated 04 / 17 / 2026, page 27 / 87 / 8 of vertically arranged railway tracks. The photovoltaic panel and equipment box are statically fixed to the upper end of this structure. Performing preventive maintenance procedures, such as cleaning the panel surfaces, replacing battery units, and inspecting the electrical system, requires operators equipped with ladders to reach the installation site. This work-at-height methodology inherently introduces accident risks and potential ergonomic problems for the maintenance team.

[004] In contrast, the second model, known as an articulated pole, has a distinct configuration. It consists of a vertical structural profile firmly fixed to the ground, the upper end of which integrates an articulation mechanism. This mechanism allows the controlled movement of a second profile, usually operated by a ratchet system. The main functionality lies in the structure's tilting capability, enabling maintenance activities to be carried out at ground level, mitigating the risks associated with working at height.

[005] However, a significant limitation inherent in the currently existing articulated pole model lies in the absence of a robust safety system for the tilting stage. This safety gap introduces potential accident risks, particularly in scenarios of failure or breakage of the steel cable responsible for supporting the moving part of the structure. The consequences of such events can cause injuries to operators resulting from the impact of the structure falling on them or from the whiplash effect of the tensioned cable when it breaks. Additionally, the integrity of the installed equipment may be compromised due to the impact of the fall and material damage to the pole structure itself. State of the Art Analysis

[006] Research conducted in specialized databases found documents relating to railway poles, such as document no. BR 10.2022.016782-6, which deals with a barrier fall detector, whose function is to improve the detection and signaling of the collapse or sliding of materials. Petition 870260036303, dated 04 / 17 / 2026, page 28 / 87 / 8 natural obstacles, such as rocks, trees and / or soil, in locations near railways or highways, in cuts and / or hills; it consists of: tension detection sensor; wire or screen; support post; ratchets; the tension detection sensor consists of a protective box; hook tensioner; sensor box and internal mechanism; the system consists of monitoring slopes near railways and highways, in order to signal, through visual, audio or radio frequency signaling, the rupture of the monitoring barrier;This barrier is assembled as follows: at one end, a post is installed that supports all the electromechanical sensors. Connected to these sensors are wires / screens, which are stretched to the other end of the slope, so that if a collapse / detachment of materials such as rocks, earth, trees, or other vegetation that could obstruct the path occurs, it will cause these wires to break, consequently triggering the sensor devices.

[007] Document No. CN202279000 presents a railway solar cell panel that provides a row of pillars arranged respectively on both sides of the railway, and the top of the pillar is provided with a steel beam. A connecting strip is arranged between two steel beams. Steel plates are paved and bonded to the upper surface of the steel beam, and a layer of insulated plate is paved and bonded to the upper surface of the steel plate. The upper surface of the insulated plate is paved and bonded with a layer of solar cell panel. The cell panel carries two sets of wires with one set of wires being connected to the national power grid and the other set being connected to bare wires below the steel beam. The bare wire makes contact with an elastic arc arranged on the top of a train. The arc guide is connected to the electrical equipment of a train.Sunlight hits the solar panels, generating electricity. Some of this electricity is used to power a train, while the majority is fed back into the national electricity grid.

[008] Thus, it is a fact that the documents cited in the paragraphs above, despite belonging to the same field of application, do not present any of the characteristics of the object now being improved, thus guaranteeing that it meets the Petition 870260036303, dated 04 / 17 / 2026, page 29 / 87 / 8 legal requirements for patentability.

[009] The objective of the present utility model is to present an arrangement introduced in a railway pole with a lifting and anti-fall locking mechanism for linear movement of a solar panel elevator and related equipment, said lifting mechanism comprising a crank with a steel cable that moves the linear carriage until the primary anti-fall mechanism locks and a secondary mechanism that is activated in case of cable breakage, enabling the controlled descent of the carriage with the equipment.

[010] Another objective of the present utility model is to present a railway pole with a lifting and anti-fall locking mechanism that aims to solve the drawback of the prior art related to the risk of accidents caused by working at height for models with a fixed panel on the poles and the risk of accidents due to the breaking of the steel cable of the articulated model poles.

[025] The present utility model refers to the “ARRANGEMENT INTRODUCED IN RAILWAY POLE WITH LIFTING AND ANTI-FALL LOCKING MECHANISM FOR LINEAR MOVEMENT OF SOLAR PANEL ELEVATOR AND RELATED EQUIPMENT”, railway pole (10) installed along the railway track (not illustrated) formed by a vertical structure (11) in the shape of a railway track and equipped with Petition 870260036303, dated 04 / 17 / 2026, page 31 / 87 / 8 solar panel (PS) and various equipment (EQ), such as batteries, lighting fixtures and related items.

[026] According to the present utility model, said railway pole (10) is equipped with a lifting mechanism (13B) and locking mechanism (13A) for a linear car (12) on the pole (10) with a support (SP) for a solar panel (PS) and an equipment box (CX) (EQ), said lifting mechanism (13B) being composed of an actuating crank (13b3) from the manual winch (13b1) connected to a steel cable (CA) for raising (SB) or lowering (DC) the linear car (12) (see figures 5B and 5C) according to the longitudinal axis (E1) of the structure (11), as well as providing a reducer (13b6) with a vertical spindle (13b7) for automatic lifting of the car (12).The locking mechanism (13A), also incorporated in the linear carriage (12), provides a primary mechanism (M1) formed by a static lock (12D) of the carriage (12) on the head (13a1) of the pole (10) maintaining the carriage (12) in its elevated position and a secondary mechanism (M2) acting as an additional lock, which is formed by a primary lock (12c1) and a secondary lock (12c3), the latter gripping the guides of the vertical structure (11) to brake the carriage (12) by friction when the steel cable (CA) breaks.

[027] Said linear carriage (12) is formed by a two-part metal frame consisting of a front part (12A) and a rear part (12B) that enclose the perimeter of the pole (10), which are connected to each other by transverse bolts (PF1). Part (12A) is formed by a pair of identical and mirrored L-shaped plates (CP1) / (CP2) whose longitudinal section (12a1) receives a platform (12a2) for supporting the solar panel (PS) support (SP), as well as each receiving rollers (12a3) for sliding in relation to the contact side of the vertical structure (11). Both plates (CP1) / (CP2) are connected to the rear part (12B) by means of the aforementioned bolt (PF1) and (PF2).

[028] The rear part (12B) has a body ordinarily in U-shape whose longitudinal section (12b1) receives a pair of internal rollers (12b2) for sliding in relation to the vertical structure (11), as well as receiving a storage box (CX) for equipment (EQ) and the upper end receives a locking block (12C) with a primary L-shaped lock (12c1) fitted and supported on its respective roller (12b2) which moves the lock (12c1) in the forward or backward movement for gripping the secondary lock (12c3) in Petition 870260036303, dated 04 / 17 / 2026, page 32 / 87 / 8 guides of the vertical structure (11) when the steel cable (CA) breaks, with the secondary lock (12c3) parallel to the roller (12e) guiding the cable (CA) tied to the eyelet (12c1') of the primary lock (12c1). The upper face of the locking block (12C) receives the static locks (12D) formed by split lances with opposite tips (12d1) / (12d2) for locking the carriage (12) in the head (13a1).

[029] Said locking mechanism (13A) (see figures 4A and 4B) comprises a “T” shaped head (13a1) installed at the upper end of the vertical structure (11) with a transverse portion having lower accesses (13a2) for the static locks (12D) to pass through and separated by boxes (13a3) with projecting movable teeth (13a4) that retract by means of upward displacement of the static locks (12D). The upper face of the head (13a1) receives an upper pulley (13a5) for guiding the cable (CA), while the lateral face of the head (13a1) receives a support (13b8) for the spindle (13b7).

[030] The locking of the static locks (12D) (see figure 4C) occurs by means of the passing of the lance (12d1) in relation to the access (13a2) anchoring itself on the movable teeth (13a4) of the locking head (13a1) of the locking mechanisms (13B) of the vertical structure (11). The teeth (13a4) retract by means of upward displacement of the opposite lance (12d2), joining both lances (12d1) / (12d2) and enabling passage through the access (13a2) without any engagement between the teeth (13a4).

[031] Said lifting mechanism (13B) (see figures 1, 5A, 5B and 5C), in turn, provides a manual winch (13b1) that accommodates a set of gears (13b2) driven by the rotation of a crank (13b3) after counterclockwise rotation of the profile (13b4) to unlock the locking teeth (13b5) in relation to the gear (13b3') of the crank (13b3). On the side of the vertical structure (11) is installed a reducer (13b6) for supporting a vertical spindle (13b7) (see figure 1) with the opposite end anchored in a support (13b8) mounted on the head (13a1) to vertically move the linear carriage (12) in case of cable breakage (CA), being driven by means of a side shaft (13b9) of the reducer (13b6) that receives a battery-powered screwdriver (not shown).

[032] For lifting (SB) the linear carriage (12) it is necessary to release the locking teeth (13b5) and rotate the crank (13b3) of the winch (13b1) to lift the linear carriage (12) to the upper end of the post (10). During movement, the Petition 870260036303, dated 04 / 17 / 2026, page 33 / 87 / 8 lance (12d1) of the static lock (12D) hits the first engagement formed by the teeth (13a4) of the head (13a1), locking the carriage (12).

[033] For lowering (DC) the car (12) the crank (13b3) is operated again until the spear (12d2) reaches the teeth (13a4), pushing them into the boxes (13a3) and releasing the static lock (12D) thus allowing the car (12) to descend.

[034] In case of cable breakage (CA), the car (12) can be raised or lowered by attaching the battery-powered screwdriver (not shown) coupled to the reducer shaft (13b6), being operated clockwise to perform the raising and counterclockwise to perform the lowering.

[035] The preferred embodiment of the present utility model has been described, and any modifications and / or alterations should be understood as being within the scope of the utility model presented.
