Description

Technical Field

[0001] The present invention relates to the technical field of construction machinery, and particularly to a multi-platform operation device for the maintenance of overhead catenary systems on tracks. Background Art

[0002] Currently, with the rapid development of railways, especially high-speed railways, conventional railways, subways, and intercity railways, the demand for the construction and maintenance of overhead catenary systems, poles, etc. has increased sharply. In the above-mentioned construction and maintenance operations, it is necessary to transport personnel to an appropriate height and ensure their safety. In the prior art, in order to achieve the construction and maintenance of overhead catenary systems and poles, a scissor lift platform or a telescopic column structure is generally used to lift personnel to the corresponding working height. However, due to the limitations of the inspection line and pole structure, after the operating personnel rise to a certain height, they cannot continue to rise.

[0062] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0063] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0064] It should be noted that the orientation terms such as "upper end, lower end, left side, right side" described below are defined based on the accompanying drawings of the specification.

[0065] As Figure 1 and Figure 2 shown, the multi-platform operation device for overhead catenary maintenance provided by the embodiment of the present invention includes a locomotive 1, a first lifting platform device 2, an integrated operation platform assembly, and a second lifting platform device 6; wherein, the first lifting platform device 2 is arranged on the top of the locomotive 1, and the first lifting platform device 2 can perform telescopic movement in the vertical direction; the integrated operation platform assembly is connected to the locomotive 1 through a telescopic mechanism 11, and the integrated operation platform assembly can realize rotational movement in the vertical direction, extension movement in the horizontal direction, and telescopic movement in the vertical direction. Correspondingly, the integrated operation platform assembly can be set to include platforms with three different functions, specifically, a main platform mechanism 3 that can rotate in the vertical direction, a sub-platform mechanism 4 that can extend in the horizontal direction, and an auxiliary platform mechanism 5 that can telescope in the vertical direction. Among them, the sub-platform mechanism 4 is arranged between the main platform mechanism 3 and the auxiliary platform mechanism 5, and the sub-platform mechanism 4 is movably connected to the main platform mechanism 3 to realize extension movement in the horizontal direction. An auxiliary platform mechanism 5 that can telescope in the vertical direction is provided at the end of the sub-platform mechanism 4 away from the main platform mechanism 3; the second lifting platform device 6 is arranged on the top of the locomotive 1, and the second lifting platform device 6 can transport operating personnel to the first lifting platform device 2 or the integrated operation platform assembly.

[0066] Preferably, both the first lifting platform device 2 and the second lifting platform device 6 can be set as devices including a platform and a lifting mechanism. Among them, the lifting mechanism is arranged below the platform, and the lifting mechanism can specifically be a scissor mechanism or a rotary lifting mechanism.

[0067] Of course, the number of upper platforms of the integrated operation platform assembly can be adjusted according to actual needs, and specific limitations are not made herein. For example, according to the extension requirement, the number of sub-platform mechanisms 4 located between the main platform mechanism 3 and the auxiliary platform mechanism 5 can be set to at least two to meet the extension requirement of the operation device in the horizontal direction, and adjacent sub-platform mechanisms 4 are connected by sliding.

[0068] It can be seen that, compared with the situation in the prior art where it is impossible to transport the operating personnel to the designated working area due to various factors such as overhaul lines and column structures, the multi-platform operating device for overhead contact line maintenance provided by the embodiments of the present invention can transport the operating personnel to the designated working area through the setting of multiple platforms with different functions. Specifically, the operating personnel on the locomotive 1 reach the first lifting platform device 2 or the integrated operating platform assembly through the second lifting platform device 6 that can move telescopically in the vertical direction. Among them, the first lifting platform device 2 can move telescopically in the vertical direction, and the operating personnel are transported to the designated height through the telescopic movement of the first lifting platform device 2; when it is impossible to reach the designated working area by using the telescopic movement in the vertical direction, the operating personnel can be sent to the integrated operating platform assembly. Since the integrated operating platform assembly integrates the functions of rotation, extension, and lifting, the operating personnel can be transported to the designated working area through the rotational movement in the vertical direction, the extension movement in the horizontal direction, and the telescopic movement in the vertical direction of the integrated operating platform assembly.

[0069] The above setting method adopts the multi-platform method, without considering the influence of the parking position of the locomotive 1 and the catenary support columns, and can achieve the purpose of transporting the operating personnel to the designated working area; at the same time, continuous and uninterrupted transportation can be realized, thus solving the problem that it is necessary to climb the ladder twice to reach the designated position, which can not only significantly improve work efficiency but also ensure the safety of the operating personnel.

[0070] The multi-platform operating device for overhead contact line maintenance provided by the embodiments of the present invention will be specifically described below.

[0071] As Figure 3 shown, the locomotive 1 includes a bogie 101, a car body 102, a girder 103, and a staircase 104. The girder 103 is located at the bottom of the car body 102, and the staircase 104 is located on the side of the car body 102. The staircase 104 is the entrance for the operating personnel to enter the working platform from the inside of the car body 102.

[0072] As Figure 4 and Figure 5As shown in the figure, the first lifting platform device 2 may specifically be configured to include a first lifting platform 204 and a lifting platform scissor mechanism disposed between the first lifting platform 204 and the locomotive 1. Specifically, the lifting platform scissor mechanism includes a lifting platform scissor base 201, a lifting platform scissor arm assembly 203, and a lifting platform scissor drive assembly 202; the lifting platform scissor base 201 is installed on the top surface of the locomotive 1, one end of the lower part of the lifting platform scissor arm assembly 203 is hinged to the lifting platform scissor base 201, the other end of the lower part is connected to the lifting platform scissor base 201 in a rolling manner, one end of the upper part of the lifting platform scissor arm assembly 203 is hinged to the first lifting platform 204, and the other end of the upper part is connected to the first lifting platform 204 in a rolling manner; the fixed end of the lifting platform scissor drive assembly 202 is hinged to the lifting platform scissor base 201, and the movable end of the lifting platform scissor drive assembly 202 is hinged to the lifting platform scissor arm assembly 203.

[0073] Preferably, the above-mentioned lifting platform scissor drive assembly 202 may specifically be a scissor oil cylinder, and the opening and closing of the lifting platform scissor arm assembly 203 are realized through the telescopic movement of the piston rod of the scissor oil cylinder, thereby driving the lifting of the first lifting platform 204.

[0074] In addition, a first lifting platform guardrail and an end folding guardrail 205 are further provided on the first lifting platform 204. Among them, the first lifting platform guardrail is used to protect the safety of operating personnel, and the end folding guardrail 205 is installed on the first lifting platform guardrail. The end folding guardrail 205 can be closed by manual folding, and the first lifting platform device 2 can be connected to the main platform mechanism 3 of the integrated operation platform assembly through the end folding guardrail 205.

[0075] Such as Figure 6 and Figure 7As shown in the figure, in order to facilitate the overall lifting movement of the integrated operation platform assembly, the main platform mechanism 3 is connected to the locomotive 1 through the telescopic mechanism 11. Specifically, the telescopic mechanism 11 can be set as a column telescopic mechanism, and the column telescopic mechanism is installed on the bottom surface of the girder 103 of the locomotive 1. Specifically, the column telescopic mechanism includes a column basic arm 1101, a first-stage column telescopic arm 1102, a second-stage column telescopic arm 1103, a first-stage column telescopic oil cylinder 1104, and a second-stage column telescopic oil cylinder 1105 arranged from outside to inside; the adjacent arm bodies of the column basic arm 1101, the first-stage column telescopic arm 1102, and the second-stage column telescopic arm 1103 are all slidably connected through column sliders 1106. The column basic arm 1101 is installed on the top surface of the girder 103. The top of the second-stage column telescopic arm 1103 is equipped with a leveling device for keeping the main platform mechanism 3 horizontal. One end of the first-stage column telescopic oil cylinder 1104 is hinged to the column basic arm 1101, and the other end is hinged to the first-stage column telescopic arm 1102. One end of the second-stage column telescopic oil cylinder 1105 is hinged to the first-stage column telescopic arm 1102, and the other end is hinged to the second-stage column telescopic arm 1103. The first-stage column telescopic oil cylinder 1104 and the second-stage column telescopic oil cylinder 1105 are respectively used for the telescopic movement of the arm bodies of the first-stage column telescopic arm 1102 and the second-stage column telescopic arm 1103, so as to realize the lifting of the main platform mechanism 3, the auxiliary platform mechanism 4, and the auxiliary platform mechanism 5.

[0076] Of course, the number of the above-mentioned telescopic arms can also be set to more than two according to the telescopic needs, and this article does not make specific restrictions on this.

[0077] As Figure 8 and Figure 9 shown in the figure, further, in order to realize the leveling function of the main platform mechanism 3, the auxiliary platform mechanism 4, and the auxiliary platform mechanism 5, a leveling mechanism 9 is provided at the top of the above-mentioned column telescopic mechanism. The leveling mechanism 9 includes a leveling base 901, a leveling drive assembly 902, and a leveling locking drive assembly 903; wherein, the leveling base 901 is rotatably connected to the second-stage column telescopic arm 1103 through a pin shaft; the fixed end of the leveling drive assembly 902 is hinged to the top of the second-stage column telescopic arm 1103, and the movable end of the leveling drive assembly 902 is hinged to the bottom of the leveling base 901; in addition, locking holes are provided at the bottom of the leveling base 901 and the top of the second-stage column telescopic arm 1103, and the movable end of the leveling locking drive assembly 903 can extend horizontally into the locking holes of the leveling base 901 and the locking holes of the second-stage column telescopic arm 1103 to keep the leveling base 901 in a horizontal state.

[0078] Of course, according to actual needs, the above leveling drive assembly 902 can specifically be set as a leveling oil cylinder, and the leveling locking drive assembly 903 can specifically be set as a leveling locking oil cylinder. When the locomotive 1 is on a non-horizontal plane, the leveling base 901 can rotate along the axis of the pin shaft driven by the leveling oil cylinder, so that the upper end surface of the leveling base 901 is in a horizontal state, ensuring that each platform mechanism installed on the top surface of the leveling mechanism 9 can work in a horizontal state; when the leveling base 901 is in a horizontal state, the piston rod of the leveling locking oil cylinder is inserted into the locking holes of the leveling base 901 and the second-stage telescopic arm 1103 of the column, keeping the leveling base 901 horizontal even after the leveling oil cylinder fails, so as to maintain the horizontal state of the working platform.

[0079] As Figure 10 shown, in order to realize the rotation function of the main platform mechanism 3, a rotation mechanism 8 for the main platform mechanism 3 to rotate in the vertical direction is provided below the main platform mechanism 3. Specifically, the rotation mechanism 8 includes a slewing speed reducer 801, and the slewing speed reducer 801 is installed on the top surface of the leveling base 901, and the main platform mechanism 3 is installed on the top surface of the slewing speed reducer 801.

[0080] In addition, in order to make the rotation angle of the rotation mechanism 8 within a preset range (±120° slewing range), a limit block is provided on the top surface of the leveling base 901, and the limit block is adapted to the main platform base 301 of the main platform mechanism 3, which is used to limit the maximum rotation angle.

[0081] It should be noted that the positional relationship among the above column lifting mechanism, leveling mechanism 9, rotation mechanism 8, and main platform mechanism 3 is as follows: the leveling mechanism 9 is installed on the column lifting mechanism, the rotation mechanism 8 is installed on the leveling mechanism 9, and the main platform mechanism 3 is installed on the rotation mechanism 8.

[0082] As Figure 11 and Figure 12As shown in the figure, the main platform mechanism 3 includes a main platform base 301, a main platform guardrail 304, a main platform guardrail drive assembly 305, a main platform guardrail stop link 306, a main platform guardrail long link 307, a main platform guardrail short link 308, and a main platform guardrail locking drive assembly 309. Among them, the main platform guardrail 304 is connected to the main platform base 301 through a main platform linear guide 303. The slider of the main platform linear guide 303 is installed on the main platform guardrail 304, and the guide rail of the main platform linear guide 303 is installed on the main platform base 301 through a main platform guide rail mounting plate 302. In this way, the up-and-down movement guidance of the main platform guardrail 304 can be realized through the main platform linear guide 303.
