Description

Technical Field

[0001] The invention relates to a pipeline transportation device under complex geographical conditions such as mountains and hills and a use method thereof, belonging to the field of pipeline installation. Background Art

[0002] At present, the construction and transportation of coalbed methane long-distance pipelines in complex environmental conditions such as mountains and hills involves secondary transportation of pipes, which is often restricted by geographical conditions. For example, the construction access road is narrow, and the temporarily widened access road cannot meet the needs of large-scale transportation vehicles and cranes. This has the following disadvantages: 1. Widening the temporary access road requires additional labor, materials, and machinery, which increases the cost of construction measures; 2. Even if the access road allows construction machinery to pass, secondary transportation can only be carried out by construction machinery, which is not cost-effective and the reduced transportation efficiency leads to serious idleness, resulting in increased labor costs; 3. The undulating ground increases the risk of transportation. Ultimately, it increases the overall construction cost.

[0003] Therefore, there is an urgent need to provide a transportation device that can get rid of the dependence of secondary handling on geographical conditions and large-scale transportation machinery, reduce transportation costs, improve labor productivity, and be safe and reliable. These are technical problems that need to be solved. Summary of the invention

[0004] The present invention aims to provide a pipeline transportation device suitable for use in complex geographical conditions such as mountains and hills and a method for using the same. The device is easy to assemble and disassemble, quick to use, and improves transportation efficiency.

[0005] The present invention is mainly designed for pipeline transportation under complex geographical conditions. The pipeline to be installed is placed on the device, and the built-in motor of the device is controlled to drive the front and rear casters to move forward at a constant speed. The artificial auxiliary rods on the left and right sides are used as stability controls when turning or crossing obstacles during transportation. One pipe is transported and welded, and the pipeline installation operation is completed in this cycle.

[0006] The present invention provides a pipeline transportation device under complex geographical conditions, comprising a pipeline arc-shaped bearing member, a bearing connecting pipe, an artificial auxiliary rod, a power device, a ball bearing, a bearing bearing device, a square connecting plate, a caster fixing plate, a caster, and a caster transmission device; The arc-shaped pipe bearing member is an arc-shaped structure, which is convenient for bearing the pipe. A bearing connecting pipe is vertically arranged at the bottom center of the pipe arc-shaped bearing member. The lower part of the bearing connecting pipe is connected to the ball bearing. An artificial auxiliary rod is horizontally and vertically arranged in the middle of the bearing connecting pipe. The ball bearing is fixed above the bearing bearing device. The bearing bearing device is a channel steel. Four groups of caster transmission devices are symmetrically arranged on both sides of the channel steel, which are respectively connected to the four groups of casters. A power device is arranged inside the bearing bearing device. The power device includes a motor and a motor transmission shaft. The power device is connected to the caster transmission device, and the caster transmission device includes a belt. The transmission relationship of the present invention is: the motor in the channel steel is connected to the caster through a belt, and the belt connects the shaft of the caster with the motor transmission shaft; the two shafts are in the horizontal direction and the belt is in the vertical direction.

[0007] In addition, the present invention can also be operated by an automatic control device, which includes a remote control, a controller and a battery. The remote control adopts PS2CTRL, and the controller adopts an STM32 main control board (with a built-in signal receiving device and a multi-function module). The battery provides power for the signal receiver and the controller. The control principle is: when the receiver receives the signal, it will transmit the signal to the decoder for decoding and conversion into a control signal. According to the different signals, the built-in multi-function module of the controller controls the speed, forward rotation and reverse rotation of the motor to control the device to move forward, backward, stop and adjust the running speed, thereby realizing the movement of the device.

The length of the artificial auxiliary rod can be adjusted according to the construction site conditions, and the auxiliary rod can be extended by threaded connection.

[0011] Furthermore, the bearing bearing device is 16# channel steel.

[0012] Furthermore, the casters are heavy-duty casters.

[0013] Furthermore, the diameter of the pipeline transported by the device is DN250mm~DN350mm, and the length is 6~8m.

[0014] Furthermore, the thickness of the caster fixing plate is 6 mm.

[0015] Furthermore, four ends of the square connecting plate are provided with through holes, and belts pass through the through holes to respectively connect the transmission shaft at the upper part of the square connecting plate and the caster shaft at the lower part of the square connecting plate.

[0018] The present invention provides a method for using the pipeline transportation device under the above-mentioned complex geographical conditions, comprising the following steps: (1) To transport a long pipeline, two pipeline transport devices are required to be used together. Before transportation, the two pipeline transport devices are placed above the installed pipeline. (2) Then, use a lifting tool to lift the pipeline to be transported onto the pipeline arc-shaped bearing member. The specific design position is: a pipeline transport device is set at the front and rear ends of the bottom of the pipeline to be transported, and the distance between each pipeline transport device and the end of the pipeline to be transported is 300 mm (that is, the distance between the front pipeline transport device and the front end of the pipeline to be transported is 300 mm, and the distance between the rear pipeline transport device and the rear end of the pipeline to be transported is 300 mm); (3) During transportation, the overall stability of the transport device needs to be intervened by manual auxiliary rods to ensure stable transportation, and the pipeline is driven forward by controlling the power device when transporting it; (4) Transport one and install one, then continue on.

[0019] Furthermore, during the transportation process of step (3), when the front-end pipeline transportation device encounters a flange (the installed pipeline needs a flange connection at the position where the valve is installed), the front-end of the pipeline to be transported is first lifted by a small hydraulic jack, and then the front-end pipeline transportation device is moved in the opposite direction to a position 1 meter away from the front-end of the pipeline to be transported (that is, the device is about 1 meter away from the front end of the pipeline and 0.7 meters away from the flange), and then it is placed and continued to be pushed forward; after the end of the pipe extends out of the flange by 1 meter, the front-end pipeline transportation device is then crossed over the flange or obstacle by an artificial auxiliary rod, and the front-end pipeline transportation device is returned to a position 0.3 meters away from the front end of the pipeline to be transported, and it is pushed forward, and the pipeline to be transported gradually moves forward; when the rear-end pipeline transportation device encounters a flange or obstacle, the rear-end pipeline to be transported is lifted by a small hydraulic jack, and the rear-end pipeline transportation device is crossed over the flange or obstacle by an artificial auxiliary rod, and then it is placed under the pipeline to be transported and continued to move forward, thereby completing the transportation of the pipeline.

In addition, the transportation process is safe and reliable, which improves the effectiveness of engineering construction. BRIEF DESCRIPTION OF THE DRAWINGS
