Description

Technical Field

[0001] The utility model belongs to the technical field of electric power construction equipment, and relates to an attitude adjusting device for a crossing platform and a mobile crossing platform. Background Art

[0002] During the construction of wire erection or wire removal in electric power construction, affected by topography and landforms as well as line channels, it is inevitable to cross ground facilities such as houses, roads, railways, etc. and existing transmission lines. In order to ensure that the transmission line can safely and smoothly cross these obstacles during the construction process, it is often necessary to set up a crossing device for wire laying construction operations.

[0003] Traditional crossing devices are usually temporary structures built with wooden materials or steel pipes. The crossing devices are manually built from bottom to top on both sides of the facility to be crossed to ensure the formation of a safe supporting member during wire passing construction to meet the requirements of safe wire passing construction. However, the construction and demolition of traditional crossing devices require a large amount of manpower, material resources and time, and the materials for building the crossing devices often cannot be reused, resulting in high construction costs. Due to the cumbersome operation, the construction period of traditional crossing device construction is relatively long, and it is also necessary to close the road or cut off the power supply during the crossing of facilities such as roads and railways, causing inconvenience to the normal production and life in the surrounding areas of wire laying construction. In addition, the manually built crossing devices are sometimes not firm, there are potential safety hazards, and there are also relatively high safety risks during the process of construction workers building and demolishing the crossing devices.

[0004] At present, the problem of long construction period and potential safety hazards in the construction method of traditional crossing devices can be solved by a mobile crossing platform. The crossing platform is lifted and lowered relying on a crane or other base equipment, and can be quickly deployed during construction. Its umbrella-shaped truss mechanism is automatically and quickly deployed by full hydraulic control to form a netting plane. After the construction is completed, it can be quickly withdrawn. However, this solution and other similar solutions still have deficiencies. Once the umbrella-shaped truss mechanism is deployed after the deployment is completed, the formed netting plane can only adjust the attitude by moving the boom of the crane, and achieve the ideal angle and netting position through the limited swing of the boom. However, in the actual process of electric power wire laying construction, the directions of facilities such as roads or lines that need to be protected under the construction line are ever-changing, there are various situations, and the crossing platform with a fixed angle position cannot adapt to the complex situation on site and protect it at the most suitable position. Adjusting the attitude of the netting plane of the crossing platform relying on the crane boom not only has limited adjustment positions and is difficult to meet the requirements of the construction site, but also is time-consuming and laborious, and is prone to touching other buildings and causing accidents.

[0039] Embodiment 1

[0040] As Figures 1 to 7 shown, the attitude adjustment device for crossing the platform in this embodiment includes a connecting seat 1, a bottom plate 2, a slewing mechanism 3, and a pitching mechanism 4.

[0041] The connecting seat 1 of this embodiment is located at the bottommost part of the attitude adjustment device. The lower end of the bottom plate 2 is connected to the connecting seat 1. The connecting seat 1 is preferably arranged at the four corners of the lower surface of the bottom plate 2. The bottom plate 2 is fixedly connected to a crane (or other base equipment, such as an aerial work platform, etc.) through the connecting seat 1.

[0042] The slewing mechanism 3 is arranged on the bottom plate 2. The slewing mechanism 3 includes a slewing motor 31, a slewing bearing 32 and a turntable 33. Among them, the fixed end of the slewing bearing 32 is connected to the bottom plate 2, and the rotating end of the slewing bearing 32 is connected to the turntable 33; the slewing motor 31 is power-connected to the slewing bearing 32 to drive the rotating end of the slewing bearing 33 to rotate relative to the fixed end; one end of the frame assembly 6 is connected to the turntable 33. The lower end of the frame assembly 6 is hinged to the turntable 33. A gear ring is arranged at the rotating end of the slewing bearing 33. The output rotating shaft of the slewing motor 31 is connected to a driving gear, and the driving gear meshes with the gear ring. The slewing mechanism 3 drives the rotating end of the slewing bearing 32 to rotate relative to the fixed end through the slewing motor 31, thereby driving the turntable 33 to rotate, and thus changing the rotation angle of the frame assembly 6.

[0043] One end of the pitching mechanism 4 is connected to the slewing mechanism 3, and the other end of the pitching mechanism 4 is connected to the frame assembly 6. The pitching angle of the frame assembly 6 is changed by the contraction and extension of the pitching mechanism 4. The pitching mechanism 4 preferably adopts a luffing cylinder. The upper end of the luffing cylinder is hinged to the frame assembly 6, and the lower end of the luffing cylinder is hinged to the turntable 33. When the telescopic end of the luffing cylinder contracts, the angle between the frame assembly 6 and the bottom plate 2 increases; when the telescopic end of the luffing cylinder extends, the angle between the frame assembly 6 and the bottom plate 2 decreases.

[0044] The pitching mechanism 4 can also select an electric push rod, and the pitching angle of the frame assembly 6 is changed by the extension and contraction of the electric push rod. Similarly, when the telescopic end of the electric push rod shortens, the angle between the frame assembly 6 and the bottom plate 2 increases; when the telescopic end of the electric push rod extends, the angle between the frame assembly 6 and the bottom plate 2 decreases.

[0045] It should be noted that the pitching mechanism 4 is not limited to the luffing cylinder and the electric push rod. The pitching mechanism 4 can also be set as a lead screw connected to a power source, and the above power source can adopt a motor or an electric machine.

[0046] Through the slewing mechanism 3 and the pitching mechanism 4, the frame assembly 6 can perform pitching and rotating movements relative to the boom (or other base equipment). The attitude adjustment device enables the angle position to be adjusted according to the directions of facilities such as roads, lines or fixed buildings under the construction line after the boom assembly 61 of the frame assembly 6 is unfolded, so as to meet the requirements of crossing operations in complex working environments during the ground wire stringing construction of electric power construction.

[0047] The attitude adjustment device for crossing platforms in this embodiment further includes a power unit 5, which is arranged on the bottom plate 2. The power unit 5 supplies power for the self-rotation of the slewing mechanism 3 and / or the self-contraction and elongation of the pitching mechanism 4. The power unit 5 preferably supplies power hydraulic oil as the power source for the slewing motor 33, the luffing cylinder, and the retracting and extending motor 62 in the frame assembly 6. The power unit 5 can also include a power battery. The slewing motor 33 and the retracting and extending motor 62 can be electrically driven, and the pitching mechanism 4 can also use an electric push rod.

[0048] When the attitude adjustment device for crossing platforms in this embodiment is in use, first fix the bottom plate 2 to the top end of the boom of the crane (or other base equipment) through the connecting seat 1. After the bottom plate 2 is connected to the boom of the crane, lift the mobile crossing platform 6 in place by the crane, and then control the retracting and extending motor 62 to start, and unfold the umbrella-shaped boom assembly 61 of the frame assembly 6 through the retracting and extending motor 62. After the unfolding is completed, change the pitching angle of the frame assembly 6 through the pitching mechanism 4 to adjust the frame assembly 6 to a horizontal state. After the pitching angle of the frame assembly 6 is adjusted, change the rotation angle of the frame assembly 6 through the slewing mechanism 3 to form a large angle or be perpendicular to the construction direction of the wire. After the stretching attitude is adjusted, the wire erection or disassembly construction of the power construction can be carried out.

[0049] Embodiment 2

[0050] A mobile crossing platform is provided with the attitude adjustment device for crossing platforms as described in Embodiment 1.

The mobile crossing platform adjusts its attitude according to different directions of the construction line to meet the operation requirements in the complex operation environment during the power construction, improving its operation efficiency and reliability. In addition, the frame assembly realizes the adjustment and leveling of the angle through pitching and rotation movements, giving the equipment carrying the frame assembly, such as the crane, a greater free choice space for the docking position, thereby improving the adaptability of the mobile crossing platform to the operation environment.
