Description

A type of tracked aerial work platform Technical Field

[0001] This application relates to the field of railway maintenance technology, specifically to a tracked aerial work platform. Background Technology

[0002] A tracked aerial work platform is a high-altitude work device specifically designed for railway scenarios. It combines the complex terrain adaptability of a tracked chassis with the functionality of an aerial work platform. Primarily used for the inspection and maintenance of railway overhead contact lines, it can also be extended to other high-altitude work scenarios such as railway or highway signal installation and tunnel cleaning. For example, patent CN217756791U discloses a track-walking aerial work platform for railway power maintenance. This platform uses a dual-shaft motor to drive two gears mounted on its output shafts. The rotation of these two gears drives two meshing gears, which in turn rotate the two front wheels, propelling the device forward. When the platform reaches a power maintenance point, maintenance personnel on the right climb onto the platform via an auxiliary ladder, and the operator presses the control button to activate the lifting motor. The control button is activated, causing the lifting motor to rotate, which in turn rotates the lead screw shaft. This rotation moves two threaded sleeves to the sides, causing two connecting rods to move and stand upright, thus raising the lifting platform and transporting maintenance personnel to a higher position for repairs. While the aforementioned patent allows for movement on the track and maintenance at heights, it fails to provide protection for workers during the process. Since railway tracks are mostly outdoors, outdoor weather is unpredictable. For example, during hot summer months, the weather is extremely hot, forcing workers to be exposed to direct sunlight. Prolonged maintenance could lead to heatstroke or other health risks, and direct sunlight could also interfere with eye health, affecting maintenance efficiency. Therefore, it is necessary to provide a tracked elevated platform vehicle to address these issues.

Detailed Implementation

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] As shown in Figures 1 and 2, this application provides a tracked aerial work platform, including a tracked vehicle 1. The tracked vehicle 1 is suitable for traveling on the ground and moving between two sets of railway tracks. A traveling assembly 3 is provided on the tracked vehicle 1, which is suitable for traveling on the tracks. Specifically, the traveling assembly 3 includes fixed boxes 35 located on the outer sides of both ends of the tracked vehicle 1. Hydraulic cylinders 36 are hinged to both sets of fixed boxes 35, and the output ends of the two sets of hydraulic cylinders 36 are respectively hinged to both ends of the tracked vehicle 1, so as to drive the fixed boxes 35 to rise or fall under the drive of the hydraulic cylinders 36. Two sets of equipment boxes 32 are slidably arranged inside the two sets of fixed boxes 35. A motor is fixedly installed inside the equipment box 32. A roller 31 is fixedly installed at the output end of the motor, located outside the equipment box 32. Hydraulic cylinders are fixedly installed inside both sets of fixed boxes 35, with their output ends connected to the equipment box 32. Initially, both sets of fixed boxes 35 are in an elevated state. When the tracked vehicle 1 moves between the two sets of railway tracks, the two sets of hydraulic cylinders 36 are activated, causing the two sets of fixed boxes 35 to descend, and consequently, multiple sets of rollers 31 to descend until they are positioned on the surfaces of the two sets of tracks. At this point, the tracks of the tracked vehicle 1 are suspended in the air. Then, multiple motors are driven, causing the rollers 31 to rotate, allowing the tracked vehicle 1 to move along the tracks until it reaches the maintenance point. For tracks with different spacing, the hydraulic cylinder can be activated, which in turn drives the roller 31 to extend and retract via the equipment box 32 to adapt to the different track spacing. It should be noted that an electric winch can also be installed on one of the fixed boxes 35 to assist the tracked vehicle 1 in climbing ladders and escaping in emergencies. At both ends of the two fixed boxes 35, there are clamping robotic arms 33. The clamping robotic arms 33 are existing technology, and their specific structure and principle will not be described in detail here. As shown in Figure 2, the clamping robotic arms 33 have two sets of grippers that are close to or far apart from each other along the long side of the fixed box 35. Auxiliary wheels 34 are rotatably mounted on both sets of grippers so that the clamping robotic arms can be activated when the roller 31 is on the track. 33 drives the two sets of auxiliary wheels 34 to move closer to each other until they are in contact with both sides of the track, so as to prevent the rollers 31 from leaving the track when moving. When facing tracks with different spacing, the opening angle of the auxiliary wheels 34 can be controlled so that one set of auxiliary wheels 34 is in contact with the inner side of the track, so as to prevent the top of the track during the operation and ensure the movement of the working basket on the rail in the normal working position, so as to achieve continuous operation at height. It should be noted that the clamping mechanical arm 33 can also be replaced with telescopic hydraulic outriggers, which can be leveled with one click on ordinary uneven road surfaces that are not on rail tracks, ensuring the safety of climbing. The tracked vehicle 1 is equipped with a climbing component 2, which is suitable for sending workers to high places.As shown in Figures 1-4, the climbing assembly 2 includes a climbing unit 21 rotatably mounted on the tracked vehicle 1. The climbing unit 21 has a steering part 202 mounted on the tracked vehicle 1, which is adapted to rotate vertically. A climbing robotic arm 201 is mounted on the steering part 202, and a basket 22 is mounted on the robotic arm 201. The basket 22 is made of multiple sets of welded railings, and a control unit 23 is mounted on the basket 22. The steering part 202, the climbing robotic arm, and the walking assembly 3 are all connected to the control unit 23. In the initial state, the robotic arm 201 controls the basket 22 to be at a low position to facilitate personnel entering the basket 22, and at this time, the tracked vehicle 1... Located between two sets of tracks, the worker then drives the walking assembly 3 to the maintenance point via the control unit 23, activates the steering unit 202 to rotate to the appropriate position, and uses the climbing robotic arm 201 to send it to the height where maintenance is needed. 360° panoramic cameras can also be installed around the suspended platform 22 to achieve all-around, blind-spot-free detection of the area around the platform to prevent collision risks, and provide audible and visual alarms when the platform falls below a preset safe distance. An upper clamping ring 45 is provided on the outside of the railing of the suspended platform 22, with a lower clamping ring 46 hinged to it. The lower clamping ring 46 can move closer to or away from the upper clamping ring 45 under external force, and when it approaches the upper clamping ring 45, it forms a clamping position suitable for holding the platform. The railing has a circular shape; referring to Figure 4, a groove 49 is provided at one end of the lower clamping ring 46, and a screw 48 is hinged to one end of the upper clamping ring 45. A nut 47 is threaded onto the screw 48. When the lower clamping ring 46 and the upper clamping ring 45 are clamped onto the railing of the suspended basket 22, the screw 48 is rotated into the groove 49, and the nut 47 is rotated until it abuts against the lower clamping ring 46 to fix the lower clamping ring 46 and the upper clamping ring 45. A vertical rod 41 is provided on the upper clamping ring 45, and a supporting mechanical arm 4 is provided on the vertical rod 41. A sunshade 42 is fixedly installed on the supporting mechanical arm 4, so that when the staff performs maintenance at a height, the supporting mechanical arm 4 can be adjusted. The sunshade 42 is moved overhead to block sunlight, preventing prolonged exposure during maintenance. The position of the supporting robotic arm 4 on the basket 22 can be adjusted as needed. Two sets of round rods 43 are fixedly installed on the sunshade 42, with a fan 44 rotatably mounted on each rod. The friction between the fan 44 and the rods 43 is significant, allowing the fan 44 to rotate under external force and remain at a fixed angle. During maintenance, the fan 44 can be adjusted to a suitable angle and then activated to provide ventilation for the workers, reducing the risk of heatstroke during maintenance in hot outdoor weather.

[0019] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
