Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel construction equipment, specifically relating to a multi-mode transfer and switching water ditch cable trough trolley with one frame on both sides of a railway tunnel. 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, the formwork on both sides of the trolley and the trolley gantry occupy a certain amount of space in the filling surface, significantly reducing the passage space for excavation and muck removal vehicles and invert lining construction vehicles. Traditional construction methods require the trolley's wheels to reach the bottom of the trench to allow passage in the middle. 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 multi-mode transfer and switching cable trough trolley with one frame on both sides of a railway tunnel. The gantry travels on the filling surface, and the traveling hinged column can be retracted through the hinge device to give way to the passage space. Since the gantry travels on the filling surface, 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 multi-mode transfer and switching trolley for cable troughs on both sides of a railway tunnel includes a gantry. The gantry includes four sets of horizontally sliding and lifting columns arranged at the front and rear. The horizontally sliding and lifting columns are fixedly connected by crossbeams. The vertically sliding and lifting columns are fixedly connected to an upper truss of the gantry. A traveling mechanism is provided below the upper truss of the gantry. The traveling mechanism includes traveling hinged columns arranged at both the front and rear ends. The traveling hinged columns are hinged below the upper truss of the gantry. A self-propelled mechanism is provided at the bottom of the traveling hinged columns. The traveling hinged columns are located inside the horizontally sliding and lifting columns. Cable trough templates are suspended on both sides of the upper truss of the gantry.

[0007] Furthermore, the walking hinge column is a multi-segmented joint, and a telescopic hydraulic cylinder is provided inside the walking hinge column. The top walking hinge column is hinged to the truss on the gantry.

[0008] Furthermore, an articulated hydraulic cylinder is installed on the side of the top traveling articulated column to control the traveling articulated column to move to the side.

[0009] Furthermore, temporary scissor braces are installed between the walking hinged columns.

[0010] Furthermore, a hoist walkway beam is installed on the gantry truss, and an electric hoist is movably installed on the hoist walkway beam.

[0011] Furthermore, the bottom of the translational lifting column is provided with translational support legs.

[0012] 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.

[0013] Compared with the prior art, the present invention has the following beneficial effects through the above technical solution:

[0014] This utility model provides a multi-mode transfer and switching gantry cable trough trolley with two sides in a railway tunnel. The gantry travels on the filling surface, and the traveling hinged column can be retracted through a hinge device to allow passage for vehicles. The translation and lifting column is equipped with a lifting cylinder and translation outriggers to adjust the trolley's position. The traveling hinged column is equipped with a hinge, a traveling telescopic sleeve, and a solid rubber wheel motor with reduction drive. When the cable trough trolley is traveling, a temporary scissor brace device is manually added to increase the stability of the gantry's movement, preventing vehicles from passing through the middle.

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.

[0023] 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.

[0024] 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”.

[0025] 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.

[0026] like Figure 1-3 As shown, this utility model provides a railway tunnel double-sided multi-mode transfer and switching water ditch cable trough trolley, including a gantry. The gantry includes four sets of translational lifting columns 1 arranged at the front and rear. Each translational lifting column 1 is equipped with a lifting cylinder and translational support legs at the bottom, which can adjust the position of the trolley. The lateral translational lifting columns 1 are fixedly connected by crossbeams, and the longitudinal translational lifting columns 1 are fixedly connected to the upper truss 2 of the gantry. A traveling mechanism 4 is provided below the upper truss 2 of the gantry. The traveling mechanism 4 includes traveling hinged columns 3 arranged at both the front and rear ends. There are four rows of columns at the front and rear ends of the trolley, with the inner spacing of the traveling hinged columns 3 at 2.5 meters and the outer spacing of the translational lifting columns 1 at 5 meters. The traveling hinged columns 3 are hinged below the upper truss 2 of the gantry, and the bottom of the traveling hinged columns 3 is provided with a self-propelled mechanism 4. The traveling hinged columns 3 are located inside the translational lifting columns 1. Water ditch cable trough templates 5 are suspended on both sides of the upper truss 2 of the gantry.

[0027] like Figure 5 As shown, in this embodiment, the traveling hinged column 3 adopts a multi-segment traveling telescopic sleeve. A telescopic hydraulic cylinder is installed inside the traveling hinged column 3. The top traveling hinged column 3 is hinged to the upper truss 2 of the gantry. A hinged hydraulic cylinder 6 is installed on the side of the top traveling hinged column 3 to control the lateral movement of the traveling hinged column 3. The traveling hinged column 3 contains a telescopic hydraulic cylinder; before the traveling hinged column 3 is retracted, the vertical hydraulic cylinder is retracted first, and then the top side hinged hydraulic cylinder 6 is retracted.

[0028] like Figure 4 As shown, in this embodiment, temporary scissor braces 7 are installed between the walking hinged columns 3. When the cable trough trolley moves, it does not pass through the middle; the temporary scissor braces 7 are manually added to increase the stability of the gantry movement.

[0029] In this embodiment, a hoist walkway beam 8 is installed on the gantry truss 2, and an electric hoist 9 is movably installed on the hoist walkway beam 8.

[0030] In this embodiment, the cable trough template 5 is an integral structure, using screw jacks for loosening. When the cable trough template 5 is used for lining, it requires necessary reinforcement to prevent lateral displacement and upward floating during the pouring process.

[0031] When the gantry is in an unoccupied state, it travels to the location where a cable trench has been constructed on one side. At this point, the horizontal lifting column 1 is lowered, the four legs support the ground, and the gantry travels on the filled surface. The traveling hinged column 3 can be retracted via the hinge device to allow passage for vehicles. First, the vertical hydraulic cylinder retracts, and then the top side hinged hydraulic cylinder 6 is retracted, leaving a passage space of 3.6 meters in the middle of the gantry. Because this gantry travels on the filled surface, the complex working conditions at the bottom of the trench can be ignored, giving it a significant advantage during travel.
