Description

Double-layer large-diameter steel pipe delivery counterpart device in the tunnel

technical field

The invention relates to a car body with a fork lift extension device and a matching detachable and adjustable temporary pipe support. The pipe group composed of the two supports and the upper and lower double-layer pipes is transported in place through the car body, and the pipe alignment is realized through the temporary pipe support. . Specifically, it is a combination device that can realize the delivery of double-layer large-diameter pipelines in the tunnel and realize the function of independently adjusting the counterparts of each layer of pipelines.

Background technique

In heating cities in the north, large-scale combined heat and power central heating has become very popular. At present, the largest central heating pipe has a diameter of DN1400. After using polyurethane prefabricated insulation, the outer diameter of the insulation pipe has reached nearly 1.7m. In recent years, with the increasing pressure of environmental protection and the determination of the country to control smog, vigorously developing clean energy heating has become an important means to control smog and improve the environment. As a clean energy source, gas is expensive and the amount of gas is insufficient. my country's coal-based energy structure has created a long-term existence of coal-fired heat and power cogeneration as a major heating method. With the improvement of the urban environment and the needs of the city appearance, coal-fired cogeneration is moving away from the urban area and is developing towards large-scale centralization. Therefore, long-distance long-distance large-scale central heating has become a development direction, limited by pipe diameters. The joint laying of double pipelines will also occur many times. In the central and western regions, when laying long-distance heating pipelines, it is inevitable to cross mountainous areas. The nature of the heating project determines that the heating pipelines cannot pass through the high hump terrain. With the emergence of high points, heating tunnels become the only option when crossing mountainous areas.

In the heating tunnel, the 4 heating pipelines in double trips are generally laid in an overhead manner. In order to make use of space, the pipelines are generally arranged in two rows on the left and right, stacked up and down, and the maintenance and installation channel is in the middle, and the channel is generally relatively compact. When the tunnel is very long and has curvature, the track can not only improve the safety of two-way rapid passage, but also facilitate construction and maintenance. In addition, the track has a high bearing capacity, which can realize rapid lifting and save the extra extension required by ordinary lifting equipment. It saves the time for supporting legs and improves work efficiency.

The upper and lower layers of pipelines are arranged in two layers. No matter which pipeline is installed first, there will be problems of mutual influence, and the space for maintenance and passage in the tunnel is relatively narrow. If the vehicle stops at a certain place for hoisting, it will affect the passage of other pipelines. Therefore, the preliminary transportation In-place and counterpart installation must be carried out separately in order to improve the efficiency of pipeline installation. Adjustable and detachable brackets are used to integrate the upper and lower layers. Using the car body with a fork lift extension device, the group of pipes and brackets are initially in place, and the car body can return to transport the second pipe group, and the pipes Individual alignment can be performed with two adjustable and detachable brackets already in place.

There is a "tunnel transport vehicle" in the current reference patent literature, patent number 200420061303.6 and "tunnel large-diameter steel pipe transport device", patent number 20081016652.9. Its main feature is the transportation of single-pipe pipes, and it cannot realize the independent operation functions of transportation and pipe alignment. It is only suitable for the installation of single-layer large-diameter pipes in tunnels, and cannot meet the needs of rapid installation of large-diameter double-layer pipes.
