Technical Field

[0002] The contact network is a special form of transmission line erected above the railway line to supply power to electric locomotives. It is a key component of the electrified railway power supply system. Due to long-term exposure to the outdoors, especially in high-altitude and cold areas, it is very easy to form ice due to low temperature weather. The ice will not only increase the vertical load of the contact network, but also affect the normal current collection of the pantograph. Therefore, it is necessary to remove the ice on the contact network in time.

[0003] The main method for solving the problem of contact network icing in the prior art still relies on manual deicing. Although it can temporarily alleviate the harm caused by icing, it has low operating efficiency, poor safety, and consumes a lot of manpower, material and financial resources. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a six-axis swing-type deicing mechanism, which solves the technical problems of low efficiency, poor safety and large consumption of manpower and material resources in the prior art deicing methods, and has the advantages of effectively improving deicing efficiency and high safety.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: a six-axis swing-type deicing mechanism, comprising a mounting base plate, a U-shaped support plate fixedly mounted on the mounting base plate, a knocking ice-breaking mechanism and an ice-breaking auxiliary mechanism provided on the U-shaped support plate, a tensioning adjustment mechanism provided inside the U-shaped support plate, during the movement of the deicing vehicle, the knocking ice-breaking mechanism and the ice-breaking auxiliary mechanism will automatically knock and remove the ice on the contact network, the tensioning adjustment mechanism will ensure the normal transmission and avoid tooth jumping, the knocking ice-breaking mechanism comprises a bearing mounting seat arranged on the U-shaped support plate, a rotating circular shaft is movably mounted on the bearing mounting seat, a four-mouth coupling key is fixedly mounted on one end of the rotating circular shaft, a transmission sleeve is fixedly mounted on the other end of the rotating circular shaft, a swing rod assembly is symmetrically arranged on the four-mouth coupling key, a mounting bracket is fixedly mounted on the mounting base plate, a driving gear is movably mounted on one side of the mounting bracket, a driving motor is fixedly mounted on the other side of the mounting bracket, the driving motor is transmission-connected to the driving gear, and the rotating circular shaft is coaxially and fixedly connected to the transmission sleeve.

[0006] Preferably, the swing rod assembly consists of a nylon swing rod and a lock, and the nylon swing rod and the four-port coupling key are movably connected through the lock, and when the four-port coupling key rotates with the rotating circular shaft, the nylon swing rod will repeatedly collide with the ice on the contact network.

[0007] Preferably, a transmission toothed belt is provided between the transmission sleeve and the driving gear. When the driving gear rotates under the action of the driving motor, the plurality of transmission sleeves will rotate synchronously through cooperation with the transmission toothed belt.

[0008] Preferably, two U-shaped support plates are provided, and each U-shaped support plate is respectively provided with three bearing mounting seats. The bearing mounting seats near both sides of the mounting base plate are movably connected to the U-shaped support plate. By adjusting the bearing mounting seats, the tension of the transmission toothed belt can be adjusted, thereby ensuring normal transmission.

[0014] Beneficial effects:

[0015] 1. The present invention sets a knocking and ice-breaking mechanism and utilizes the mutual cooperation between the rotating circular shaft and the swinging rod assembly. When the de-icing vehicle moves horizontally along the railway line, multiple swinging rod assemblies will repeatedly knock on the contact network at the same time, thereby removing the ice on the contact network.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] The main method to solve the problem of overhead line icing in the prior art still relies on manual knocking to remove ice. Although it can temporarily alleviate the harm caused by icing, it has low efficiency, poor safety, and consumes a lot of manpower, material and financial resources. In order to solve this technical defect in the prior art, Figure 1-Figure 4 As shown, the present embodiment proposes a six-axis swing-type deicing mechanism, which can effectively improve the efficiency of ice removal compared with the manual knocking in the prior art. The deicing mechanism includes a mounting base plate 1, on which a U-shaped support plate 2 is fixedly mounted, and the U-shaped support plate 2 is provided with a knocking ice-breaking mechanism 3 and an ice-breaking auxiliary mechanism 4, and the interior of the U-shaped support plate 2 is provided with a tensioning adjustment mechanism 5. During the movement of the deicing vehicle, the knocking ice-breaking mechanism 3 and the ice-breaking auxiliary mechanism 4 will automatically knock and remove the ice on the contact network, and the tensioning adjustment mechanism 5 will ensure the normal transmission and avoid tooth jumping.

[0033] In order to improve the ice crushing efficiency as much as possible, the present embodiment is provided with a knocking ice-breaking mechanism 3. Specifically, the knocking ice-breaking mechanism 3 includes a bearing mounting seat 301 arranged on the U-shaped support plate 2. Two U-shaped support plates 2 are arranged, and three bearing mounting seats 301 are respectively arranged on each U-shaped support plate 2. The bearing mounting seats 301 close to the two sides of the mounting base plate 1 are movably connected with the U-shaped support plate 2. By adjusting the bearing mounting seats 301, the tension of the transmission toothed belt can be adjusted to ensure the normal transmission. A rotating circular shaft 302 is movably installed on the bearing mounting seat 301, and a four-mouth coupling key 303 is fixedly installed on one end of the rotating circular shaft 302, and a transmission sleeve 304 is fixedly installed on the other end of the rotating circular shaft 302. A swing rod assembly 305 is symmetrically arranged on the four-mouth coupling key 303. The swing rod Component 305 consists of a nylon swing rod and a lock. The nylon swing rod and the four-way coupling key 303 are movably connected through the lock. When the four-way coupling key 303 rotates with the rotating circular shaft 302, the nylon swing rod will repeatedly collide with the ice on the contact network. A mounting bracket 306 is fixedly installed on the mounting base 1. A driving gear 307 is movably installed on one side of the mounting bracket 306. A transmission toothed belt is arranged between the transmission sleeve 304 and the driving gear 307. When the driving gear 307 rotates under the action of the driving motor 308, multiple transmission sleeves 304 will rotate synchronously through cooperation with the transmission toothed belt. A driving motor 308 is fixedly installed on the other side of the mounting bracket 306. The driving motor 308 is transmission-connected to the driving gear 307, and the rotating circular shaft 302 is coaxially fixedly connected to the transmission sleeve 304.

[0034] According to the above content, when the deicing vehicle moves horizontally along the railway line, the driving gear 307 will rotate rapidly under the action of the driving motor 308, and when the driving gear 307 rotates, it will make multiple driving sleeves 304 rotate synchronously through cooperation with the transmission belt.

[0035] When the transmission sleeve 304 rotates, the rotating circular shaft 302 will rotate at a constant speed. When the rotating circular shaft 302 rotates, the four-port coupling key 303 and the swing rod assembly 305 will rotate synchronously. The simultaneous rotation of multiple swing rod assemblies 305 will repeatedly strike the contact network, which can cause the ice on the contact network to fall off quickly.

[0036] In this embodiment, a knocking and ice-breaking mechanism 3 is provided, and the cooperation between the rotating circular shaft 302 and the swing rod assembly 305 is utilized. When the de-icing vehicle moves horizontally along the railway line, multiple swing rod assemblies 305 will simultaneously and repeatedly knock on the contact network, thereby removing the ice on the contact network. Compared with the manual knocking in the prior art, the efficiency of ice removal can be effectively improved; moreover, in this embodiment, a knocking and ice-breaking mechanism 3 is provided, and the nylon swing rod and the four-port connecting shaft key 303 are movably connected by a lock, so that the swing rod can undergo a certain displacement during the contact with the ice, which can not only ensure the ice crushing effect, but also reduce the vibration generated during the knocking and collision process to a certain extent.

[0037] Embodiment 2

[0038] In order to accelerate the dissolution rate of the ice as much as possible during the ice crushing process, based on the first embodiment, as shown in FIG. Figure 1 , Figure 5 as well as Figure 6 As shown, the present embodiment is provided with an ice-breaking auxiliary mechanism 4. Specifically, the ice-breaking auxiliary mechanism 4 includes a rotating protrusion 401 fixedly mounted on the outside of the rotating circular shaft 302, a push switch 402 is arranged on the U-shaped support plate 2, a plurality of injection holes 403 are opened on the U-shaped support plate 2, a storage box 404 is detachably mounted inside the U-shaped support plate 2, the storage box 404 is filled with liquid snow-melting agent, a pushing piston 406 is tightly fitted with the inner wall of the storage box 404, and when the pushing piston 406 moves horizontally along the storage box 404, the snow-melting agent is sprayed upward through the injection holes 403. The electric telescopic structure 405 is provided in the middle of the material storage box 404, and the push switch 402 is electrically connected to the electric telescopic structure 405 through a wire. Initially, the push switch 402 is in an off state. When the rotating protrusion 401 contacts the push switch 402, the push switch 402 will be turned on. Subsequently, the electric telescopic structure 405 will extend to both sides respectively. Pushing pistons 406 are symmetrically provided on both sides of the electric telescopic structure 405. When the rotating circular shaft 302 rotates, the rotating protrusion 401 will rotate synchronously, and the rotating protrusion 401 will squeeze the push switch 402 when it rotates.

[0039] According to the above content, during the ice crushing process, the rotating shaft 302 will rotate at a constant speed, and the rotating protrusion 401 will rotate synchronously when the rotating shaft 302 rotates. When the rotating protrusion 401 rotates, it will intermittently contact the pressing switch 402.

[0040] When the rotating protrusion 401 contacts the push switch 402 (when in contact, the rotating protrusion 401 will press the push switch 402 downward, and each contact to separation will last about 2 seconds), the push switch 402 will be in the on state. At this time, the pushing piston 406 will move horizontally under the action of the electric telescopic structure 405.

[0041] When the pushing piston 406 moves horizontally, the deicing agent inside the storage box 404 will be sprayed upward through the spraying hole 403. Next, the deicing agent will contact the ice on the contact network, thereby reducing the firmness of the connection between the ice and the contact network.

[0042] The present embodiment is provided with an ice-breaking auxiliary mechanism 4, and utilizes the mutual cooperation between the spraying circular hole 403 and the storage square box 404. In the process of knocking the broken ice, a certain amount of snow-melting agent can be automatically sprayed onto the surface of the contact network, thereby accelerating the melting of the ice, and can effectively improve the effect of removing the broken ice and avoid secondary icing; moreover, the present embodiment is provided with an ice-breaking auxiliary mechanism 4, and utilizes the mutual cooperation between the electric telescopic structure 405 and the pushing piston 406. The snow-melting agent can be automatically sprayed intermittently without the need for manual operation by the staff, which can effectively reduce the workload of the staff.

[0043] Embodiment 3

[0044] In order to prevent the tooth jumping phenomenon from occurring during the transmission process, based on the above embodiment, as Figure 2 , Figure 6 as well as Figure 8 As shown, the present embodiment is provided with a tensioning adjustment mechanism 5. Specifically, the tensioning adjustment mechanism 5 includes an adjusting square groove 501 provided on the U-shaped support plate 2. The interior of the adjusting square groove 501 is slidably connected with a fixed iron block 502. An electromagnet assembly 503 is fixedly installed on the inner side wall of the adjusting square groove 501. When the electromagnet assembly 503 is energized, it will produce a magnetic attraction effect on the fixed iron block 502, thereby causing the bearing mounting seat 301 to move to both sides.

[0045] According to the above content, it can be known that during the process of knocking and crushing ice, the electromagnet assembly 503 will magnetically attract the fixed iron block 502, so that the transmission sleeves 304 located on both sides of the transmission belt move to both sides respectively.

[0046] When the transmission sleeve 304 moves, the transmission belt will be in a tensioned state, thereby ensuring that the transmission sleeve 304 and the driving gear 307 can always maintain a meshing state with the transmission belt to avoid tooth jumping.

[0047] This embodiment provides a tensioning adjustment mechanism 5 and utilizes the cooperation between the electromagnet assembly 503 and the fixed iron block 502 to automatically pull the transmission sleeves 304 at both ends to both sides during the ice crushing process, so that the transmission belt is always in a taut state, which can effectively prevent tooth jumping.

[0048] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0049] It should be noted that, in this article, the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
