Description

Technical Field

[0001] This utility model relates to the field of tunnel cable support installation, specifically a cable tunnel arc-shaped support installation device. Background Technology

[0002] Tunnels are the main transmission channels for urban power cables. Among urban tunnels, pipe jacking tunnels (precast concrete pipes with a diameter of 2 to 5 meters) are widely favored by the market due to their convenient construction and minimal damage to the ground. Their usage is increasing, and the pipe diameter is also getting larger, from the original two meters to more than five meters.

[0003] As cable capacity increases and usage areas expand, tunnel diameters also grow larger, bringing new problems and difficulties to the installation of supports for cables within cable structures.

[0004] The installation of cable supports inside tunnels presents numerous inconveniences for workers due to the curved structure of the tunnel walls. In particular, the cable supports must be laid out in all directions to make full use of the tunnel space, making the installation particularly difficult.

[0005] Currently, there is no good auxiliary equipment or installation equipment for the installation of curved columns. Traditional manual installation is difficult to achieve the expected results and efficiency. The curved shape is difficult to meet the safe operation of ordinary lifting machinery. In the limited space, ordinary lifting machinery has little room to maneuver. In particular, the curved support column will slip when installed on the curved wall, causing safety hazards. In particular, the curved support must be aligned with a certain curvature to be completely fitted to the tunnel wall. Traditional manual and mechanical installation is basically unable to achieve the goal of fast and safe installation of curved supports.

[0006] Therefore, the invention of a device capable of automating the installation of supports under the special working conditions of such a narrow arc shape will improve the efficiency and reduce the cost of support installation in tunnels, as well as enhance the safety and reliability of installation. It has very high social and economic value and will provide support for the future promotion and application of arc-shaped cable tunnels. Utility Model Content

In terms of structure, the hydraulic system supports the top wall of the tunnel and the bottom of the tunnel, ensuring the safety of hoisting and rotation in a confined space.

[0023] The lifting and rotating mechanism is used to lift the curved column and rotate the lifted curved column to push it toward the tunnel wall. Its structure is symmetrical to ensure the balance of the lifting. The left and right movements are synchronized to ensure equidistant work, so that the curved columns on both sides reach the tunnel wall at the same time. Through such installation equipment, the transportation and installation of the curved column in a narrow space are optimally combined, and the work efficiency is maximized.

[0024] Compared with traditional lifting equipment, this application can automate the installation of curved supports, thereby improving installation efficiency and reducing installation costs.

[0050] The base frame 1 is mainly used as the base and skeleton of the lifting and rotating mechanism 2 to ensure the safe operation of the lifting and rotating mechanism 2; it plays a role in movement and counterweight. The base frame 1 includes movable wheels 12 at the bottom and a vertical lifting push rod 13 for pressing at the top. The purpose of the vertical lifting push rod 13 is to use the narrow opening to push and press at the top to promote the overall effect of the base frame 1 and the wall of the cable tunnel 4, so that the base frame 1 can meet the counterweight when the lifting and spreading is opened, and ensure the safety of the lifting and spreading.

[0051] The suspension rotation mechanism 2 is connected to the base frame 1 and includes a cross lifting assembly connected to the base frame 1 and rotation opening assemblies symmetrically arranged on both sides of the cross lifting assembly;

[0052] The cross-shaped lifting assembly includes:

[0053] A lifting and fixing frame 21 is provided with a vertical lifting push rod inside the lifting and fixing frame 21;

[0054] The lifting motion frame 22 is adapted to the lifting fixed frame 21 and connected to the output end of the lifting vertical lifting push rod;

[0066] The lifting and rotating mechanism 2 is used to lift the arc-shaped column 3 and rotate the lifted arc-shaped column 3 to push it toward the wall of the tunnel 4. Its structure is symmetrical to ensure the balance of the lifting. The left and right movements are synchronized to ensure equidistant work, so that the arc-shaped columns 3 on both sides reach the wall of the tunnel 4 at the same time. Through such installation equipment, the transportation and installation of the arc-shaped column 3 in a narrow space are optimally combined, and the work efficiency is maximized.

[0073] The base frame 1 has a groove on its inner side that is adapted to the slider.

[0074] Working principle explanation:

[0075] Positioning of base frame 1: Move the installation equipment to the installation position and arrange it along the axis of tunnel 4 so that the base frame 1 corresponds to the vertical direction of the arc wall of tunnel 4, ensuring the correct installation position of the arc column 3. When moving, push the base frame 1, and the moving wheels 12 adapt to the movement stroke.

[0076] Top-down pressure: The top vertical lifting push rod 13 of the base frame 1 is activated and comes into close contact with the top of the arc-shaped tunnel 4, so that the entire base frame 1 is in a top-down pressure position, forming axial pressure;

[0077] Column in place: Move the curved column 3 to below the boom 24. A special trolley can be used to push it to the bottom of the boom 24.

[0078] Installing the column: Install the arc-shaped column 3 on the boom 24, and connect the central balance frame 32 to the lifting clamp 29 with bolts. When connecting, the arc-shaped columns 3 on both sides are installed and lifted at the same time.

[0079] Lift the column: Activate the lifting vertical lifting push rod to drive the lifting motion frame 22 to rise, lift the arc-shaped column 3 to the predetermined height, and lift the arc-shaped column 3 out of the plane of the special trolley;

[0080] Trolley withdrawal: After the curved column 3 is lifted to a certain height, the special trolley withdraws;

[0081] Continue to increase: Raise the vertical lifting push rod to continue rising until it reaches a certain height and then stops;

[0082] Start the diagonal brace push rod 26: Start the diagonal brace push rod 26 to slowly push the boom 24 from the vertical direction to the horizontal direction. Stop when the boom 24 is pushed to the horizontal center position of the arc tunnel 4 and 10 degrees upward.

[0083] Activate horizontal push rod 27: Activate horizontal push rod 27 to push the cantilever 25 hidden in boom 24 outward to one meter from the vertical center line of tunnel 4 (to ensure the rotation space of the arc column 3);

[0084] Start the rotating head 28: Start the rotating head 28 installed on the cantilever 25, rotate the arc-shaped column 3 from its original horizontal position by 90 degrees, and rotate it to the vertical direction to ensure that it is compatible with the wall of the arc-shaped tunnel 4. Then the rotating mechanism stops.

[0085] Continue to activate the horizontal push rod 27 until the arc-shaped column 3 is pushed against the arc-shaped groove wall and the work is completed.
