[0001] This utility model relates to the field of maintenance technology for transportation electromechanical equipment, specifically a transportation electromechanical maintenance equipment. Background Technology

[0002] When maintaining existing transportation electromechanical equipment, especially large pieces of equipment that are typically at a considerable height, workers usually need to use ladders or stepladders to access and perform maintenance. However, existing maintenance equipment suffers from significant instability, particularly during work at heights. The equipment is prone to swaying due to uneven ground or external forces, increasing the difficulty of operation and posing considerable safety hazards. Furthermore, existing maintenance equipment lacks an effective stability adjustment mechanism, failing to quickly adjust its support status according to different working environments, resulting in poor adaptability to complex conditions. Therefore, improvements to existing technologies are urgently needed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a transportation electromechanical maintenance equipment, which has the advantages of improving the stability of the equipment when working at height, effectively adapting to different terrain conditions, and reducing safety hazards.

[0004] This application provides a traffic electromechanical maintenance equipment, the technical solution of which is as follows: it includes a base, and a stability enhancement component is provided at the bottom of the base. The stability enhancement component includes a movable box, and the movable box is located at the bottom of the base. A bidirectional electric push rod is provided in the inner cavity of the movable box. The two output ends of the bidirectional electric push rod pass through and extend to both sides of the movable box. An L-plate is fixedly sleeved on both output ends of the bidirectional electric push rod. A threaded sleeve is fixedly sleeved in the inner cavity of the L-plate. A screw is threadedly connected to the inner cavity of the threaded sleeve. A rotating plate is provided on the top of the screw. A limit plate is fixedly connected to the bottom of the screw.

[0005] Furthermore, this application also proposes that mounting plates are fixedly connected to both ends of the two sides of the active box, and the inner cavity of the mounting plate is fixedly installed to the base by mounting bolts.

[0006] Furthermore, this application also proposes that a box is fixedly connected to the top of the base, and hydraulic rods are provided on both sides of the bottom of the box cavity. The output ends of the two hydraulic rods are provided with bearing seats, and fixed guardrails are provided around the top of the bearing seats. A protective frame is fixedly connected to the top of the fixed guardrails.

[0007] Furthermore, this application also proposes that two fixed guardrails at the top of the entrance of the bearing seat are movably fitted with sliding sleeves, and that a stop bar is fixedly connected to one side of the corresponding sliding sleeve.

[0008] Furthermore, this application also proposes that an escalator be provided below the entrance of the support seat, and that anti-slip particles be provided on the handrail of the escalator.

[0009] Furthermore, this application also proposes that each of the four corners of the base is equipped with a brake caster, and the four brake casters are of the same size.

[0010] Furthermore, this application also proposes that a fixing plate is fixedly connected to the bottom of the hydraulic rod, and the inner cavity of the fixing plate is fixedly connected to the housing by fixing bolts.

[0011] Furthermore, this application also proposes that limiting plates are fixedly fitted on both sides of the surface of the bidirectional electric push rod, and the bottom of the limiting plates is fixedly connected to the movable box.

[0012] As can be seen from the above, the transportation electromechanical maintenance equipment and its stability components provided in this application drive the L-plate to unfold laterally through a bidirectional electric push rod, and cooperate with the screw to adjust the contact height between the limit plate and the ground to form a multi-point adjustable support structure. This effectively solves the problem of shaking caused by uneven ground or external forces in existing equipment, and has the advantages of improving the stability of the equipment when working at height, effectively adapting to different terrain conditions, and reducing safety hazards.

[0019] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0020] Please see Figure 1-4 In existing technologies, transportation electromechanical maintenance equipment typically employs fixed support structures or simple mobile devices. When operators are working at heights, the equipment is prone to swaying due to external forces or uneven ground. Although some equipment is equipped with foundation support components, these cannot be adjusted in multiple dimensions according to the site terrain, resulting in insufficient contact area between the equipment and the ground, posing a safety hazard.

[0021] To address the aforementioned issues, researchers observed that traditional support structures, possessing only unidirectional adjustment capabilities, were ill-suited for complex operating environments. Analysis revealed that equipment sway primarily stemmed from uneven support point distribution and insufficient contact pressure. Therefore, a linkage adjustment mechanism was proposed to achieve coordinated control of lateral expansion and vertical support. Based on mechanical transmission principles, a composite stabilizing mechanism capable of simultaneously adjusting the support span and height was designed.

[0022] Therefore, this application proposes a stability component including a base 1 and a bottom thereof. The component includes a bidirectional electric push rod 1306 installed inside a movable box 1301. The two ends of the push rod extend to both sides of the box 9 and are fitted with L-shaped plates 1308. A threaded sleeve 1303 is provided inside the L-shaped plate 1308. A screw 1304 with a rotating plate 1309 is threadedly connected inside the sleeve. A limiting plate 13010 is fixed at the bottom of the screw 1304.

[0023] The bidirectional electric actuator 1306 is a linear drive device capable of bidirectional synchronous extension and retraction, specifically implemented using an electric lead screw structure, used to control the lateral displacement of the L-shaped plate 1308. The L-shaped plate 1308 is a right-angled structural component with a vertical support surface, specifically formed by bending steel plate, used to support the threaded sleeve 1303 and provide lateral support points. The threaded sleeve 1303 is a tubular component with threads on its inner wall, specifically fixed by welding with a standard nut, used to form a helical drive pair with the screw 1304. The screw 1304 is a cylindrical body with external threads on its surface, specifically implemented using a trapezoidal threaded rod, achieving vertical height adjustment through rotational movement. The limiting disc 13010 is a disc structure with a diameter larger than that of the screw 1304, specifically made of stamped steel plate, used to limit excessive extension of the screw 1304 and increase the ground contact area.

[0024] Specifically, when enhanced stability is required, the bidirectional electric push rod 1306 simultaneously pushes the L-shaped plates 1308 on both sides outward to expand the support span. The operator rotates the rotating plate 1309, causing the screw 1304 to move up and down within the threaded sleeve 1303, bringing the limiting disc 13010 into contact with the ground to form vertical support. The lateral expansion of the L-shaped plates 1308 increases the projected area of ​​the equipment's bottom surface, while the screw 1304 presses down vertically to generate preload; the two work together to form a three-dimensional stable system. After the limiting disc 13010 contacts the ground, its disc-shaped structure disperses concentrated stress, preventing the screw 1304 from sinking into soft ground.

[0025] Compared to existing technologies, traditional equipment often uses fixed outriggers or a single hydraulic support, which cannot expand the support span laterally or precisely adjust the vertical support pressure. This solution achieves coordinated control of the support span and height through a mechanical linkage mechanism, adapting to different workspace requirements and adjusting the contact pressure according to differences in ground hardness. The combination of the bidirectional electric actuator 1306 and threaded drive is more convenient for precise control and easier to maintain than a pure hydraulic system.

[0026] Through the above technical solution, this application effectively solves the problem of swaying of aerial work platforms caused by uneven terrain or insufficient support. The lateral expansion mechanism increases the stability base of the equipment, and the vertically adjustable support structure ensures that each support point is evenly stressed. The combination of these two features enables the equipment to maintain a stable posture in complex terrain. The mechanical transmission method avoids the risk of oil leakage from the hydraulic system, and the self-locking characteristic of the threads ensures the reliable maintenance of the support state.

[0027] This application further proposes that both ends of the movable box 1301 are fixedly connected to the mounting plate 1302, and the inner cavity of the mounting plate 1302 is fixedly connected to the base 1 by the mounting bolt 1305.

[0028] The mounting plate 1302 refers to the plate-like structure used to connect the movable box 1301 and the base 1. Specifically, it can be made of steel plate or aluminum alloy plate by stamping, and the assembly with the base 1 is achieved by opening through holes in the plate. This structure can distribute the load of the bidirectional electric push rod 1306 during operation and avoid stress concentration at a single connection point.

[0029] The mounting bolt 1305 is a threaded connection that secures the mounting plate 1302 to the base 1. Specifically, it can be achieved using a hexagonal head bolt and a spring washer. This fastening method prevents the connection from loosening due to vibration during equipment movement and facilitates disassembly for later maintenance.

[0030] Specifically, mounting plates 1302 are symmetrically distributed on both ends of the movable box 1301, forming a four-point fixing layout. Mounting bolts 1305 pass through the through holes in the mounting plates 1302 and are screwed into the pre-set threaded holes in the base 1. Applying pre-tightening force ensures a rigid connection between the movable box 1301 and the base 1. This structure effectively limits the horizontal displacement of the movable box 1301, preventing structural swaying when the bidirectional electric push rod 1306 is activated.

[0031] Compared to existing technologies, traditional maintenance equipment typically uses welding to fix the movable box 1301 and the base 1, which has the drawback of being unable to be disassembled for maintenance. This solution, however, uses a combination of mounting plates 1302 and bolts for connection, ensuring both connection strength and detachability. Furthermore, the symmetrically distributed mounting plates 1302 design balance the bidirectional forces generated by the bidirectional electric push rod 1306, providing better torsional resistance compared to single-sided fixing solutions.

[0032] Through the above technical solution, this application solves the problem of overall shaking of the maintenance equipment caused by the unstable connection structure. The rigid connection between the mounting plate 1302 and the base 1 effectively suppresses the displacement of the movable box 1301, and the preload of the mounting bolts 1305 can maintain the connection stability for a long time. This structure ensures the flexibility of equipment movement, provides a reliable support foundation for lifting operations, and facilitates the maintenance and replacement of internal components of the movable box 1301 in the future.

[0033] This application further proposes that the top of the base 1 is fixedly connected to the box 9, and the bottom of the box 9 is provided with hydraulic rods 10 on both sides. The output ends of the two hydraulic rods 10 are provided with bearing seats 8. The top of the bearing seats 8 is provided with fixed guardrails 7, and the top of the fixed guardrails 7 is fixedly connected with a protective frame 6.

[0034] Among them, the box 9 refers to the support structure set on the top of the base 1, which can be realized by welding or bolting a metal frame, and is used to accommodate the hydraulic rod 10 and provide lifting space for the bearing seat 8.

[0035] Among them, the hydraulic rod 10 refers to the power element that drives the vertical movement of the bearing seat 8. Specifically, it can be implemented by a double-stroke hydraulic cylinder, and the height of the bearing seat 8 can be adjusted by synchronously controlling the extension and retraction of the hydraulic rods 10 on both sides.

[0036] Among them, the support seat 8 refers to the platform structure used to support staff and equipment. Specifically, it can be made of steel plates welded to form a rectangular frame, with anti-slip texture on the surface to increase friction.

[0037] Among them, the fixed guardrail 7 refers to the protective structure set around the edge of the bearing seat 8. Specifically, it can be made of steel pipes welded into a grid-like fence, which is connected and fixed to the bearing seat 8 by bolts to prevent people from falling accidentally.

[0038] Among them, the protective frame 6 refers to the closed structure covering the top of the fixed guardrail 7. Specifically, it can be installed by combining metal beams and mesh materials to prevent external objects from falling and restrict the range of personnel movement.

[0039] Specifically, the housing 9 is fixed to the top of the base 1 by welding or bolting, and hydraulic rods 10 are symmetrically installed on both sides inside. The output end of the hydraulic rod 10 is connected to the bottom of the support seat 8, and the lifting action is synchronously controlled by the hydraulic system. Fixed guardrails 7 are vertically installed around the support seat 8, and protective frames 6 are installed on the top of the guardrails to form an enclosed space. When the hydraulic rods 10 push the support seat 8 to rise, the fixed guardrails 7 and the protective frames 6 rise accordingly, forming a stable aerial work platform.

[0040] Compared to existing technologies, traditional maintenance equipment lacks an adjustable-height support platform and protective structure, relying solely on simple ladders or open-style ladder boxes, posing a risk of personnel falls and failing to meet the maintenance height requirements of different electromechanical equipment. This solution achieves both flexible adjustment of working height and fall protection by combining a hydraulically driven lifting structure with enclosed guardrails.

[0041] Through the above technical solution, this application solves the problems of insufficient stability and lack of safety protection of the aerial work platform. The rigid connection between the bearing seat 8 and the hydraulic rod 10 ensures a smooth lifting process. The fixed guardrail 7 and the protective frame 6 form a three-dimensional protection area, which effectively prevents workers from falling due to equipment shaking or operational errors during maintenance.

[0042] This application further proposes that two fixed guardrails 7 at the top of the entrance of the bearing seat 8 are movably fitted with sliding sleeves 5, and a stop bar 4 is fixedly connected to one side of the corresponding side of the two sliding sleeves 5.

[0043] Among them, the sliding sleeve 5 refers to the sliding component sleeved on the outside of the fixed guardrail 7, which can be implemented by a ring sleeve structure with ball bearings, and its longitudinal position on the guardrail can be changed by sliding. The stop bar 4 refers to the horizontal bar connecting the two sliding sleeves 5, which can be implemented by a metal tube with a surface covered with anti-slip rubber, and is used to form a lateral blocking structure.

[0044] Specifically, the sliding sleeve 5 fits onto the surface of the fixed guardrail 7 through an annular opening, forming a movable support point at the entrance of the support seat 8. When workers need to enter the support seat 8, the stop bar 4 can move down with the sliding sleeve 5 to the bottom of the entrance as a step support; when protection is required during operation, the stop bar 4 can move up with the sliding sleeve 5 to waist height to form a fall protection barrier. The sliding fit between the sliding sleeve 5 and the fixed guardrail 7 allows the stop bar 4 to be adjusted to different heights according to operational needs, enabling functional switching without disassembly.

[0045] Compared to existing technologies, traditional maintenance equipment guardrails only have fixed horizontal bars, making it impossible to adjust the protective position according to the work scenario. This solution, through the combination of sliding sleeve 5 and stop bar 4, retains the fall prevention function of the guardrail while adapting to the safety requirements of different work stages through longitudinal sliding. For example, when the equipment is moved, the stop bar 4 can be lowered to reduce interference, and when working at height, the stop bar 4 can be raised to form effective protection.

[0046] Through the above technical solution, this application effectively solves the problem of traditional equipment having a single protective structure and being unable to be dynamically adjusted. The sliding adjustment function of the stop bar 4 can prevent the risk of slipping due to instability of the center of gravity during equipment movement or climbing. At the same time, its position adjustable feature can adapt to the protection needs of workers of different body types, improving the safety and operational flexibility of the equipment.

[0047] This application further proposes to install an escalator 3 below the entrance of the bearing seat 8, and to install anti-slip particles on the handrail of the escalator 3.

[0048] Escalator 3 refers to a climbing device with a stepped structure, which can be implemented using a foldable metal ladder frame combined with anti-slip treads. Its installation position forms a vertical channel with the entrance of the support seat 8. Anti-slip particles refer to the raised structures attached to the surface of the handrail. They can be made of rubber and fixed to the surface of the handrail through a hot-pressing process. The particle diameter is, for example, in the range of 2-5 mm, and the particle spacing is, for example, 5-8 mm.

[0049] Specifically, the escalator 3 is installed vertically below the entrance of the support seat 8, with its ladder height forming a continuous path with the working plane of the support seat 8. Anti-slip particles are distributed in an array in the handrail contact area; when an operator climbs, the contact between the palm and the particles generates frictional resistance. The step spacing of the escalator 3 can be set to 200-250 mm, the tread width is, for example, 300 mm, and the distance between the handrails on both sides is, for example, 450 mm, forming an ergonomic climbing space.

[0050] Compared to existing technologies, traditional maintenance equipment relies on independent climbing tools, and the separation of the escalator 3 from the equipment body poses a risk of slippage during the climbing process. This solution integrates the escalator 3 under the equipment support seat 8, forming a fixed climbing path. At the same time, anti-slip particles increase hand friction, solving the operational safety hazards caused by the lack of a stable climbing structure in traditional equipment.

[0051] Through the above technical solutions, this application enables operators to safely climb on the equipment body, the anti-slip particles effectively prevent hand slippage, and the direct connection between the escalator 3 and the support seat 8 avoids the risk of falling caused by the displacement of independent climbing tools, significantly improving the safety of high-altitude maintenance operations.

[0052] This application further proposes that each of the four corners of the bottom of the base 1 is provided with a brake caster 2, and the four brake casters 2 are of the same size.

[0053] Among them, the brake caster 2 refers to a steerable pulley with a locking function. Specifically, it can be implemented using a caster structure with a brake pedal, which prevents the equipment from shifting during operation by locking the wheel. "Consistent size" means that the diameter and structure of the four casters are the same, which can be achieved by using standard parts of uniform specifications to ensure that the force on each support point is even during equipment movement.

[0054] Specifically, four brake casters 2 are symmetrically arranged at the four corners of the base 1. When the equipment needs to move, the casters can turn freely to achieve flexible displacement. When the equipment reaches the working position, the brake mechanism is triggered to lock the wheels, preventing the equipment from sliding due to external forces or ground tilt. The four casters are of the same size, which keeps the equipment level during movement and prevents the equipment from tilting due to differences in wheel diameter.

[0055] Compared to existing technologies, traditional maintenance equipment often uses ordinary casters or lacks braking devices, making it prone to slipping when working on slopes or uneven ground, posing a safety hazard. This solution, by incorporating casters with locking functions and a symmetrical, equal-sized wheel structure at the four corners, retains the flexibility of equipment movement while effectively improving its resistance to displacement during operation.

[0056] Through the above technical solution, this application solves the problem of equipment slippage caused by uneven ground or external forces during operation. The four-corner symmetrical brake casters 2 structure achieves quick fixation, while the equal-sized wheel design avoids the risk of equipment tilting and ensures the overall stability of the equipment during high-altitude operations.

[0057] The bottom of the hydraulic rod 10 is fixedly connected to a fixing plate 11, and the inner cavity of the fixing plate 11 is fixedly connected to the housing 9 by fixing bolts 12. The fixing plate 11 and fixing bolts 12 can fix the hydraulic rod 10, so that the hydraulic rod 10 performs better when in use and avoids the hydraulic rod 10 from moving during use, which would lead to instability in the use of the hydraulic rod 10.

[0058] Both sides of the surface of the bidirectional electric push rod 1306 are fixedly fitted with limiting plates 1307, and the bottom of the limiting plates 1307 is fixedly connected to the movable box 1301. The limiting plates can fix the bidirectional electric push rod 1306, so that the bidirectional electric push rod 1306 performs better when used and avoids shaking during use, which would lead to instability in the use of the bidirectional electric push rod 1306.

[0059] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
