Description

The invention relates to a mobile repair workshops designed for diagnostics and repair of a ground metal main collapsible pipeline with a socket connection and can be used in repair structures in emergency situations, mainly on ground pipelines.

The number of pipeline equipment included in the set ensures the deployment of the pipeline up to 150 km in flat terrain. Pipes are the main equipment included in the sets of field main pipelines with diameters of 100 mm and 150 mm (PMTP-100 and TMTP-150), and make up 80-85% of the set weight. The length of one coarse is 6 m, and the weight is 36.2 and 80.9 kg, respectively, for sets of equipment PMTP-100 and PMTP-150 (Kravtsov M.F., Danilchenko I.G., Pirogov Yu.N., Syuzev Yu. .S. And other Field trunk pipelines of increased productivity. Operation manual (RE). - M .: Voenizdat, 1982, 368 p.).

Along with steel galvanized (or enameled) pipes included in the PMTP-100 and PMTP-150 sets, there are metal-composite pipes with a nominal diameter of 100 mm (TSR-MK-100). The body of the ТСР-MK-100 pipes is made of high-strength metal-composite materials based on the technology of a bilayer impermeable system "composite material - aluminum layer", 6 m long and 24 kg in weight (RF patent No. 2684054, IPC B60L 9/14, 03.04.2019. ).

Also, the pipeline equipment of collapsible pipelines includes shut-off and control valves with large mass-dimensional parameters (the mass of the PMTP-150 gate valve is 76 kg), which requires great efforts for loading and unloading equipment.

As the practice of using collapsible pipelines has shown, due to the large length of the pipeline route, it is periodically necessary to both complete and partially replace emergency equipment with serviceable equipment, which ensures further reliable operation of the linear part of the pipeline and environmental safety during its operation.

The authors were faced with the task of developing such a mobile tool for the repair of collapsible pipelines, which will allow not only to deliver the necessary supply of pipes, but also to promptly deliver assemblers along with equipment, spare equipment and instrumentation to control the assembly of the pipeline, as well as provide the necessary conditions life support for personnel during long-term repairs on the collapsible pipeline route, which will increase the efficiency and quality of repairs in the minimum allowable time.

When reviewing patent and scientific and technical information, several identical mobile repair shops and loading and unloading machines were identified, partially solving the assigned tasks.

Known armored vehicle, which contains a wheeled chassis, an armored body, a power compartment and a control compartment, a transfer case and a drum with a winch. The machine is equipped with a cable drive, a boom crane with a block and portable stands with adjustable height. The upper armored sheet is removable, and the side boards are folding. The machine is equipped with roller conveyor sections with the possibility of extension when the side sheets are folded back. Also, intermediate blocks and supports of the crane-boom are installed, allowing it to be installed in vertical and horizontal planes. The boom crane is made of two telescopic rods, one of which is connected to the block, and the other to one of the supports. Each of the supports of the crane boom contains a base with the possibility of rotation in a horizontal plane, as well as a locking device (RF patent No. 2240240, IPC V60R 1/54, 20.11.04).

The disadvantage of the device is the narrow functional specialization of the machine, which comes down to the performance of loading and unloading operations. Places for cargo transportation do not solve the problem posed by the authors. In addition, there are no living conditions for the personnel.

Known ground control station based on the chassis of a special vehicle. The invention relates to military and special equipment and contains a wheeled chassis, a van body, divided by partitions into three compartments. In the front part of the van body there is an operator's compartment with a rack for placing equipment, control panels for interior lighting, a generator, an independent heater and air conditioning, a work table with computer facilities and an operator's seat. The back of the box body is divided into technological and cargo compartments, located on different sides in the direction of travel. The technological compartment contains a generator based on a diesel engine and a set of spare parts and accessories. The cargo compartment contains a rigid honeycomb-type frame with cells of various sizes for containers. The cargo compartment is equipped with a folding folding side with upper and lower arrangement of components and folding ladders (RF patent No. 2407658 C1, MPK В60Р 3/14, В60Р 9/00, 27.12.10).

The disadvantages of this vehicle in relation to the problem we are solving include:

- limited functionality of the cargo compartment, such as transportation of long materials, in particular pipes 6 m long;

- no crane manipulator installation, only manual loading and unloading operations.

The closest in technical essence and taken as a prototype is a military-purpose crane-manipulator KMV-20K developed and manufactured by the Klintsy Truck Crane Plant, which is designed for transportation and laying of pipes on the route of a collapsible pipeline, placed on a four-axle chassis of a KamAZ-63501 vehicle, with a carrying capacity of 7 , 2 t, containing a crane manipulator KMU-20K, a rope sling with a lifting capacity of 6.3 t and safety equipment to protect against radio interference and seal the crane manipulator to overcome the fords (Order of the Minister of Defense of the Russian Federation No. 202 of April 13, 2019, p. 1 ).

The low efficiency of the known technical solution is due to the fact that

- there are no necessary conditions for maintenance personnel during long-term pipeline repairs or when an accident is eliminated on it;

- harsh operating conditions (compact placement of containers with special equipment is not provided);

- in case of failure of the crane-manipulator, the conditions for loading and unloading goods with large mass and dimensions deteriorate.

The technical result of the invention is an increase in efficiency due to the prompt delivery of the most necessary equipment, both with minor repairs and with a complete replacement of the pipeline section, while improving the conditions of the maintenance personnel during long-term repairs.

The specified technical result is achieved by the fact that in the known mobile technological complex for eliminating accidents on a ground collapsible oil product pipeline with a socket connection, containing a load-lifting crane-manipulator mounted on an elongated base chassis of a vehicle, fixed behind the driver's cab, for placing pipeline modules with a roof for their shelter and the side platform, according to the invention, the complex additionally contains a removable operator compartment installed at the front end of the cargo platform, on the roof of which there is a telescopic radio antenna, behind the removable operator compartment on the cargo platform at one of the sides, two metal parts are attached to the floor along its entire length narrow-gauge tracks for placing and moving rigid containers, continuing on the tailgate opening with a slope to the horizontal surface at an angle of not more than 30 °, along the other longitudinal vertical side of the cargo platform, a storage-transportation unit is made pipeline modules, consisting of rigidly attached to the floor in two rows of metal vertical racks, along the height of each of which there are coaxial holes spaced from each other at a distance of at least 1.5 times the diameter of the pipeline module, in which horizontal jumpers are rigidly fixed with placed on them on a certain distance by rotating rollers with cradles, the depth of which is not less than 1/3 of the diameter of the pipeline module, and fixation elements are made at the free end of the vertical struts, excluding vertical and horizontal movements of the pipeline modules during their transportation to the accident site, the roof of the cargo platform is made in the form of a rigidly connected with the front end of the cargo platform of a flexible corrugated awning, moving up to the displacement limiter along the U-shaped guides, which are fixed on the outer longitudinal ends of the cargo platform, while the metal narrow-gauge tracks on the rear side are telescopic in one hundred touching the ground.

The mobile technological complex consists of an all-terrain elongated base chassis 1 (KamAZ-63501), a driver's cabin 2, a crane-manipulator 3 attached to it and a loading platform 4 (Figs. 1, 2).

The roof 5 is rigidly attached to the front end of the cargo platform 4, made of a flexible corrugated awning, as an option from a canvas fabric. The roof 5 moves on wheels 6 to the limiter 7 along the guides 8 of a U-shaped form, which are fixed on the outer side of the longitudinal sides of the cargo platform 4 (Fig. 3).

A removable operator's compartment 9 is located on the cargo platform, on the roof of which a removable telescopic radio antenna 10 is installed in a folded form, which provides reception and transmission of radio signals and communication with the control center. To remove the compartment 9 and unload it on the ground by the manipulator crane 3, lugs 11 are provided (Figs. 1, 2).

On the cargo platform 4 there is a storage unit - transportation (out of position) of pipeline modules 12, which is a metal vertical struts 13, which are rigidly attached to the floor of the cargo platform using U-shaped fastening brackets 14. For the passage of fastening brackets 14 at the ends of the base plate 15, coaxial holes 16 are made. The height of the racks is selected based on the maximum diameter of the pipeline modules used for replacement, as an option 1 m for a pipeline with a nominal diameter of D _y = 150 mm. Along the height of each rack 13, coaxial holes 17 are made, spaced apart from each other to a height of at least 1.5 times the diameter of the pipeline module, in which horizontal jumpers 18 are rigidly fixed to each other in pairs. and damage due to the close arrangement of pipeline modules 12. To facilitate the movement of pipeline modules 12 on the horizontal bridges 18, movable rollers 19 made of polymer material with cradle 20 are installed. elimination of vertical and horizontal displacements of pipeline modules 12 during their transportation to the accident site at the free end of the vertical struts are fixed elements 21 (Fig. 4).

The pipeline module 12 with the "Bell" connection is a pipe 6 meters long and 100-150 mm in diameter, at one end of which there is a collar 22 with a step to stop the locking ring, at the other - a bell 23 (Fig. 1). A rubber sealing ring and a steel locking ring with a rubber microporous lining are inserted into the annular grooves of the inner cavity of the bell (Kuryatov B.V., Tikhonov D.D., Gusev A.F. USSR author's certificate No. 265635 for the invention "Quick-disconnect socket connection of pipelines", 1969).

- образного профиля с отбортовкой, которые образуют первый и второй узкоколейные пути для размещения и передвижения по ним жесткой тары 25 (фиг. 5).Guides 24 are rigidly fixed along the entire length of the loading platform

- shaped profile with flanging, which form the first and second narrow-gauge tracks for placement and movement of rigid containers 25 (Fig. 5).

Rigid container 25 is a box, open on top, in the corners at the upper open ends of which there are lugs 26 for gripping by a manipulator crane 3 and unloading them onto the ground. Container 25 is intended for storage and transportation of installation tools and emergency equipment: one-sided and two-sided emergency clamps, emergency couplings, spare inserts 400 mm and 450 mm long, elbows at 15 °, 30 °, 45 °, 90 °). Rigid containers 25 with a large weight are stored closer to the operator compartment 9, and with a lower weight, equipped, as an option, with removable parts of the "Bell" connection (rubber O-rings, microporous rubber pads and steel locking rings) closer to the end of the cargo platform 4.

On the tailgate 27, which opens with a slope to the horizontal surface at an angle of not more than 30 °, telescopic metal guides 28 are made, with a carrying capacity of up to 200 kg when fully extended, identical and coaxial with the floor guides 24, as an option in length

Removable operator compartment 9 is designed to provide the necessary life support conditions for maintenance personnel during long-term repairs along the collapsible pipeline route. Compartment 9 is equipped with heating, ventilation and filtering units 29. There are devices for fastening firefighting equipment 30, for a universal charger powered by an on-board network and two 24 V sockets. As an option, operator compartment 9 is equipped with four folding two-tier sun loungers 31, a work table 32 and the intercom 33 installed on it. Under the lower tier of the sun loungers there are boxes 34 in which protective suits are stored for collecting spilled fuel in case of an accident. On the opposite side from the working table there is a door 35 for entry and exit of personnel into the cargo compartment (outside if the compartment is removed from the cargo platform and installed on the ground) (Fig. 6).

A mobile technological complex for eliminating accidents on a ground collapsible oil product pipeline with a socket connection is operated as follows.

Example. When pumping petroleum products through the pipeline PMTP-150, 150 km long, at one of the pumping stations the outlet pressure dropped sharply, while the inlet pressure did not change, and at the next pumping station, the inlet pressure dropped sharply to zero. This indicates that there was a rupture of the pipeline line (rupture in the connection, undermining of the pipeline). The dispatcher gives the command to stop pumping to the pumping stations, determines the place of the accident and sends a mobile technological complex to the route to eliminate accidents on the ground collapsible oil product pipeline with the “Bell” connection. Before going to the scene of the accident, the maintenance personnel completes the technological complex with the missing equipment.

The mobile technological complex is sent to the emergency section of the pipeline. All information that comes to the service personnel is transmitted by radio communication, which is provided by a removable telescopic radio antenna 10 located on the roof of the operator compartment 9.

Arriving at the site, the service personnel inspects the damaged area and finds out that the rupture has occurred in the connecting unit, and on the cuff 22 there is a cut of a part of the bead, which during assembly will cause cuts in the rubber sealing ring. To eliminate the accident (a malfunction associated with a minor leak of oil), it is required to replace the pipeline module 12, D _y = 150 mm in the pipeline line with a serviceable one.

The service personnel promptly moves the roof 5 towards the front side of the cargo platform 4 and fixes it by any known means, after which both compartments are adapted for unloading. The crane-manipulator 3 removes the rigid containers 25 with assembly tools and spare parts necessary for replacing the emergency section by the lugs 26. Then, for whatever reason, the crane-manipulator fails. Then, the tailgate 27 of the cargo platform 4 is opened and along the telescopic metal guides 28, a rigid container 25 is rolled out with removable parts of the "Bell" connection, the emergency section. Further, the clamps 21 are opened and the operative unloading of the serviceable pipeline module 12 is carried out by rolling it out along the movable rollers 19 and lodgments 20. The pipe with the defective collar is removed from the line and replaced with a serviceable one. The operator of the service personnel informs about the progress of the accident elimination and the readiness of the pipeline to work on the intercom 33. After the accident is eliminated, the service personnel takes measures to collect the spilled oil product into the barrels.

At the end of the work, the mobile technological complex for the elimination of accidents goes to the location of the pumping station. The service personnel completes the technological complex with the necessary equipment and goes to re-inspect the pipeline section.

Since the inspection of the pipeline is carried out by the maintenance personnel around the clock (in accordance with the schedule for entering the highway) and long-term repair of the emergency section is possible, the removable operator compartment 9, if necessary, is unloaded to the ground with a manipulator crane 3.

Thus, the use of the proposed invention in comparison with the known technical solution will significantly reduce labor costs and significantly increase the rate of repair of collapsible pipelines from socket pipe modules 12, while improving the conditions of the maintenance personnel during long-term repairs.
