Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of tunnel construction equipment, specifically relating to a single-side frame multi-mode transfer and switching water ditch cable trough trolley for railway tunnels. Background Technology
[0002] In modern tunnel engineering, besides the safety and stability of the main structure, the layout of internal facilities is also crucial. Drainage and cable trough trolleys, as specialized construction equipment, are widely used in the construction of drainage ditches and cable troughs inside tunnels. These trolleys are mobile work platforms used to assist in laying drainage ditches and cable troughs during tunnel construction. They are typically composed of a steel structure and equipped with a walking system, positioning system, and construction operation platform. They play a vital role in tunnel engineering, not only improving construction efficiency but also ensuring construction quality and safety. By utilizing drainage and cable trough trolleys effectively, they can provide strong support for the smooth progress of tunnel engineering.
[0003] When constructing cable trenches in single-track railway tunnels, traditional construction methods require the trolley's wheels to reach the bottom of the trench to create space for trains to pass through. This can easily cause indentations and damage to freshly poured concrete after being run over by the wheels. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a single-sided multi-mode transfer and switching water ditch cable trough trolley for railway tunnels. The gantry travels on the filling surface, and the complex working conditions of the ditch bottom can be ignored, which has a great advantage when traveling.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A single-sided multi-mode transfer and switching trolley for cable trenches in railway tunnels includes a gantry, which includes front and rear gantry columns. A traveling mechanism is provided at the bottom of the gantry columns, and the traveling mechanism includes traveling wheels at the bottom. The traveling mechanism is also equipped with a hydraulic lifting and translation device for adjusting the traveling position of the gantry. A cable trench template is suspended on one side of the gantry.
[0007] Furthermore, the hydraulic lifting and translating device includes a translating lifting outrigger, which is located outside the same axis as the traveling wheel, and a lifting cylinder is provided inside the translating lifting outrigger.
[0008] Furthermore, the gantry columns are in four groups, with the horizontal gantry columns fixedly connected by crossbeams, and the vertical gantry columns fixedly connected to the upper gantry truss.
[0009] Furthermore, a hoist walkway beam is installed on the gantry truss, and an electric hoist is movably installed on the hoist walkway beam. The formwork for the water ditch cable trough is hoisted onto the electric hoist.
[0010] Furthermore, the cable trough formwork is an integral structure, using screw rods for loosening. When using the cable trough formwork for lining, necessary reinforcement is required to prevent lateral displacement and upward floating during the pouring process.
[0011] Furthermore, the walking wheels are equipped with geared motors.
[0012] Compared with the prior art, the present invention has the following beneficial effects through the above technical solution:
[0013] This utility model provides a single-sided multi-mode transfer and switching water ditch cable trough trolley for railway tunnels. The gantry travels on the filling surface, and the passage space at the bottom of the gantry can meet the passage requirements to realize a single-sided multi-mode trolley.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0021] The preferred embodiments of this utility model will be described below with reference to the accompanying drawings. It should be noted that the terms "upper," "lower," and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.
[0022] In this document, ordinal numbers such as “first” and “second” used in this application are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term “first component” does not imply the existence of a “second component”, and the term “second component” does not imply the existence of a “first component”.
[0023] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.
[0024] like Figure 1-3 As shown, this utility model provides a single-sided multi-mode transfer and switching cable trough trolley for railway tunnels, including a gantry. The gantry includes four sets of gantry columns 1 arranged at the front and rear. The transverse gantry columns 1 are fixedly connected by crossbeams, and the longitudinal gantry columns 1 are fixedly connected to the upper gantry truss 2. The bottom of the gantry columns 1 is provided with a traveling mechanism 3, which includes traveling wheels 4 arranged at the bottom and equipped with a reduction motor 9. The traveling mechanism 3 is also equipped with a hydraulic lifting and translating device 5 for adjusting the traveling position of the gantry. The hydraulic lifting and translating device 5 includes translating and lifting outriggers, which are arranged outside the same axis as the traveling wheels 4, and a lifting cylinder is provided inside the translating and lifting outriggers.
[0025] In this embodiment, a hoist walkway beam 6 is installed on the gantry truss 2. A slide rail is installed on the hoist walkway beam 6, and an electric hoist 7 is movably mounted on it. A drainage ditch cable trough template 8 is suspended below the electric hoist 7 and is hoisted onto the electric hoist 7. The drainage ditch cable trough template 8 is an integral structure, using threaded rods for loosening. When the drainage ditch cable trough template 8 is used for lining, necessary reinforcement treatment is required. Limiting anchors are pre-set and fixed at the road surface and low sidewall locations. The template is locked to the limiting anchors using lateral and bottom turnbuckles to prevent lateral displacement and upward floating of the template during pouring.
[0026] In this embodiment, the gantry travels on the filled surface. When traveling over the bottom of a trench that has already been traversed, the rubber wheels may leave imprints on the bottom of the trench. Placing a thin steel plate on the bottom of the trench before traveling provides a significant advantage when traveling. Furthermore, the space at the bottom of the gantry for passing vehicles can be increased to allow for multiple modules on one side of the gantry while meeting the requirements for vehicle passage.
[0027] like Figure 4As shown, as another possible implementation method in this embodiment, when it is necessary to meet the construction requirements of the tunnel's two-sided ditches, two sets of gantry frames are required. The two sets of gantry frames are symmetrical on the left and right, and can be used to carry out construction on the two sides of the tunnel ditches respectively.
[0028] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention.
