At present, in the deicing operation of the overhead contact system, a manual operation mode is mainly adopted for deicing. Specifically, an operator adopts a working vehicle to move along a railway track, a standing platform is arranged on the working vehicle, and when the working vehicle moves to the position below a contact net, the movement is stopped. At this time, operating personnel stand on this standing platform to adopt the stick of beating to beat the icing on the contact net, make the icing drop.

However, the manual deicing mode has extremely high requirements on deicing technology of operators, and has low deicing efficiency. Therefore, the deicing device comprises a deicing vehicle and a deicing shovel arranged on the deicing vehicle, wherein the deicing shovel is used for shoveling ice covered on a contact network in the moving process of the deicing vehicle.

However, the overhead lines on the railway have height fluctuation, namely, different positions of the overhead lines or different setting heights of overhead lines of different roots, so that the existing overhead line deicing device cannot be suitable for deicing operation of the overhead lines with the height fluctuation.

In order that the above objects, features and advantages of embodiments of the invention may be more clearly understood, a further description of aspects of embodiments of the invention will be provided below. It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of embodiments of the invention, but embodiments of the invention may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the invention.

Referring to fig. 1 to 6, the present embodiment provides a catenary deicing device, which includes a mounting base 1, a lifting assembly 2, a controller, a first image pickup unit 31, and a deicing structure 4.

The lifting assembly 2 is arranged on the bearing surface and part of the lifting assembly 2 can lift relative to the bearing surface. The mounting base 1 is arranged on the side of the lifting assembly 2 remote from the bearing surface. The deicing structure 4 is movably arranged on one side of the mounting base 1 far away from the lifting assembly 2, and the deicing structure 4 extends along the width direction of the mounting base 1, and an end face of one end of the deicing structure 4 forms an arc-shaped surface 41 for shoveling ice.

The first shooting component 31 is arranged on the mounting base 1 and is close to the arc-shaped surface 41, the first shooting component 31 is used for collecting position information of a contact net and icing information on the contact net, the controller is respectively electrically connected with the first shooting component 31 and the lifting assembly 2, and the controller is used for controlling the lifting assembly 2 to lift and controlling the deicing structure 4 to move according to the position information and the icing information so as to enable the deicing structure 4 to move to the bottom of the contact net.

In particular, before deicing operation, the position of the contact net can be detected through the first image pickup component 31, and position information of the contact net and icing information on the contact net are obtained, so that the lifting assembly 2 is controlled to lift or the deicing structure 4 is controlled to move, the deicing structure 4 is moved to the position right below the contact net, and deicing operation on the contact net through the deicing structure 4 is facilitated.

The first imaging element 31 may be, for example, a probe or a radar.

In addition, the bearing surface may be, for example, the ground, and the lifting assembly 2 may specifically include a first lifting rod 21 and a second lifting rod 22, where a base 23 at the bottom end of the first lifting rod 21 is fixed on the bearing surface, and the first lifting rod 21 has an accommodating cavity with an open top, and the second lifting rod 22 is located in the accommodating cavity and can lift relative to the first lifting rod 21, and the mounting base 1 is disposed on a mounting table 24 at the top end of the second lifting rod 22. Specifically, the second lifting rod 22 may be an electric lifting rod or a pneumatic lifting rod, so that lifting can be achieved under the control of the controller.

Further, the deicing structure 4 can move along the length direction of the installation base 1, so that the position of the deicing structure 4 can be adjusted, and the deicing operation of the contact net can be conveniently performed after the deicing structure 4 is moved to the position right below the contact net.

Specifically, when the deicing structure 4 is not located under the overhead line but has a certain offset with respect to the overhead line, the controller may control the deicing structure 4 to move and finally cause the deicing structure 4 to move directly under the overhead line. At this time, if the deicing structure 4 is lower than the contact net and cannot remove the ice coating on the contact net, the controller may control the lifting assembly 2 to rise to make the deicing structure 4 contact with the ice coating, so that the ice coating can be scraped off under the action of the arc-shaped surface 41 of the deicing structure 4, and the arc-shaped surface 41 at this time corresponds to a half-moon shovel.

In addition, when deicing operation is performed, the nose part of the deicing structure 4 of the embodiment can collide with the ice coating and the ice sliding on the contact net at first, so that most of ice edges falling below the contact net are scooped off, and a better deicing effect is achieved. The design of the half-moon shovel is adopted at the machine head part, and the machine head with the design can reduce the damage to the machine head part caused by collision with ice coating in the high-speed movement along with the overhead line operation vehicle, so that the service life of the whole automatic deicing operation robot is prolonged.

That is, in the overhead line system deicing device provided in this embodiment, when deicing operation is performed on the overhead line system, the position information of the overhead line system and the ice coating information on the overhead line system may be determined by the first image capturing component 31, so that the lifting assembly 2 is controlled to lift or the deicing structure 4 is controlled to move according to the position information and the ice coating information, so that the deicing structure 4 may move to the lower part of the overhead line system to facilitate deicing of the overhead line system, thereby being suitable for deicing operation of the overhead line system with high and low fluctuation and having high deicing efficiency.

Referring to fig. 1 to 6, in some embodiments, the catenary deicing device further includes a second image capturing component 32 electrically connected to the controller, where the second image capturing component 32 is disposed on the mounting base 1 and away from the arc surface 41, and the second image capturing component 32 is configured to collect residual ice information on the contact wire after deicing the deicing structure 4.

That is, the first image pickup device 31 and the second image pickup device 32 are disposed at intervals in a direction perpendicular to the moving direction of the deicing structure 4, for example, the first image pickup device 31 is disposed close to the arcuate surface 41, which may be regarded as a front image pickup device, and the second image pickup device 32 is disposed away from the arcuate surface 41, which may be regarded as a rear image pickup device. When the second image capturing component 32 captures whether there are more residual ice on the contact net after the blade is deiced, the second image capturing component is used for feeding back the deicing effect of the catenary deicing device of the embodiment, and can also be used for capturing whether secondary deicing operation is needed. That is, the overhead line deicing device of the embodiment adopts a plurality of deicing procedures to carry out deicing operation on the overhead line contact line, reduces icing residue on the overhead line contact line, and avoids safety accidents caused by the icing residue.

The second imaging element 32 may be, for example, a probe or a radar.

Referring to fig. 1 to 6, in some embodiments, the catenary deicing device further includes a driving member electrically connected to the controller, a sliding rail 11 extending along a length direction of the mounting base 1 is disposed at a position on the mounting base 1 corresponding to the deicing structure 4, and the driving member is used for driving the deicing structure 4 to move along the sliding rail 11 under control of the controller, so as to implement automatic adjustment of the position of the deicing structure 4, so as to reliably move the deicing structure 4 to a position directly below the catenary.

In particular, the first imaging unit 31 in this embodiment may include two probes or radars, and the second imaging unit 32 may include two probes or radars. The slide rail 11 on the mounting base 1 may also include two slide rails 11 disposed at intervals along the length direction of the mounting base 1. The specific number of settings of the first image pickup section 31, the second image pickup section 32, and the slide rail 11 may be set according to actual needs. The number of the slide rails 11 arranged on one side is two for the first image pickup unit 31 and the second image pickup unit 32 used in the present embodiment. Namely, the first image pickup part 31 and the second image pickup part 32 are respectively two and are symmetrically arranged for identifying and capturing the actual position of the contact net, and transmitting the position information of the contact net to the controller, so that the deicing structure 4 can make corresponding rotation angle adjustment and transverse displacement to track the position of the contact line of the contact net, and more efficient deicing operation is realized.

Referring to fig. 1 to 6, in some embodiments, the deicing structure 4 includes at least two deicing structures 4 spaced apart along the length direction of the mounting base 1, and adjacent two deicing structures 4 are moved on the mounting base 1 in directions toward each other or away from each other, so that deicing operations can be performed on the contact network through different deicing structures 4, respectively, to improve deicing efficiency.

When the number of the deicing structures 4 in the embodiment is two, two sets of slide rails 11 are provided in the embodiment, and the two sets of slide rail 11 devices are independently operated, so that the two deicing structures 4 are not interfered with each other and independently work when moving transversely.

Referring to fig. 3 and 4, in some embodiments, deicing structure 4 includes a base plate 42, a rapping assembly 43, a deicing shovel 44, a vibrating member 45, a swivel support 46, and a moving base 47. The moving base 47 is movably disposed at a side of the mounting base 1 remote from the elevating assembly 2, and the rotating support 46 is rotatably disposed at a side of the moving base 47 remote from the mounting base 1. The base plate 42 is disposed on a side of the rotary support 46 away from the moving base 47, the knocking assembly 43, the deicing shovel 44, and the vibrator 45 are sequentially disposed on the base plate 42 in a moving direction of the moving support 47, and the knocking assembly 43 is rotatably connected with the base plate 42. The controller is electrically connected with the knocking component 43 and the vibrating piece 45 respectively, and is used for driving the knocking component 43 to rotate so as to knock the ice coating on the contact net and is used for driving the vibrating piece 45 to vibrate so as to shake off the ice coating on the contact net.

In particular, referring to the up-down direction shown in fig. 3, the moving base 47 is movably disposed on the mounting base 1, the rotating support 46 is rotatably disposed at the top end of the moving base 47, and the moving base 47 is used for moving along the sliding rail 11 on the mounting base 1 so as to drive the whole contact net deicing device to move, so as to implement deicing at different positions of the contact net. The rotation to the seat is used to rotate with respect to the mobile seat 47 so that the angle of the deicing structure 4 can be adjusted to facilitate deicing of the contact network.

Further, the length direction of the base plate 42 may be set to, for example, a left-right direction as shown in fig. 3, the base plate 42 is disposed on top of the swivel support 46, the knocking assembly 43, the deicing shovel 44 and the vibrating member 45 are sequentially disposed on the base plate 42 in the left-right direction, and the controller may be electrically connected to the knocking assembly 43 and the vibrating member 45, respectively, that is, the knocking assembly 43 and the vibrating member 45 may be independently controlled. For example, when the controller only controls the knocking component 43 to be turned on, the knocking component 43 rotates to knock off the ice coating on the contact net, so that the deicing operation of the contact net is realized. Or when the controller only controls the opening of the vibrating piece 45, the vibrating piece 45 vibrates at the moment so as to make the ice coating on the contact net vibrate and fall off. Or, when the controller simultaneously controls the knocking assembly 43 and the vibrating member 45 to be opened, the knocking assembly 43 rotates at this moment to knock down the ice coating on the contact net, so that the deicing operation of the contact net is realized, and the vibrating member 45 vibrates so as to vibrate and drop the residual ice on the contact net knocked by the knocking assembly 43, so that the deicing efficiency and the deicing effect of the contact net are further improved.

That is, when the contact net needs to be deiced, the knocking assembly 43 and the vibrating piece 45 can be controlled by the controller to be started, at this time, the knocking assembly 43 rotates to be used for knocking down the coated ice wrapped on the contact net, and in the process that the contact net deicing device moves along the bearing surface, residual ice remained on the contact net after being knocked by the knocking assembly 43 is scraped by the deicing shovel 44, meanwhile, the coated ice and the residual ice on the contact net are vibrated and shed by the vibrating piece 45 through vibration, so that the coated ice on the contact net is effectively shed under the combined actions of the knocking assembly 43, the scraping of the deicing shovel 44, the vibration of the vibrating piece 45 and the like, and automatic deicing and high deicing efficiency can be realized.

Referring to fig. 3 and 4, in some embodiments, the tapping assembly 43 includes a first tapping rod 431 and a second tapping rod 432 rotatably coupled to the base plate 42, the first tapping rod 431 and the second tapping rod 432 being spaced apart on the base plate 42 along a moving direction of the moving support 47, each of the first and second tapping rods 431 and 432 being electrically connected to a controller for controlling rotation of the first and second tapping rods 431 and 432, respectively. The first tapping rod 431 and the second tapping rod 432 are rotated in opposite directions.

Specifically, referring to fig. 3, the first knocking rod 431 and the second knocking rod 432 are disposed at intervals along the left-right direction and are electrically connected to the controller, so that the first knocking rod 431 and the second knocking rod 432 can rotate under the control of the controller to knock off the ice coating on the contact net.

Further, the rotation directions of the first knocking rod 431 and the second knocking rod 432 are opposite, so that the first knocking rod 431 and the second knocking rod 432 can knock the ice coating on the contact net from different directions, and the knocking and falling effect of the ice coating can be further improved. For example, the first tapping rod 431 may be rotated in a forward direction and the second tapping rod 432 may be rotated in a reverse direction. Alternatively, the first tapping rod 431 may be rotated reversely, and the second tapping rod 432 may be rotated forwardly.
