Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline repair, and in particular relates to a production device for a lining hose for trenchless repair of pipelines. Background Art

[0002] In recent years, with the research on trenchless pipeline repair technology and the improvement of construction technology, it has developed into a number of trenchless pipeline repair technologies, including hose lining repair technology, U-lined HDPE pipe repair technology, short pipe lining repair technology, broken (cracked) pipe repair technology, spiral winding repair technology, stainless steel lining repair technology, etc., and has been successfully applied to various types of pipelines such as water supply and drainage, oil, gas, and electricity in many cities across the country. Among them, the most widely used trenchless repair method is the hose lining method, also known as the original curing method (CIPP), which is to line the inner wall of the existing old pipe with a soft lining layer impregnated with liquid thermosetting resin, and solidify it by heating (using hot water, hot steam or ultraviolet rays, etc.) or keeping it at room temperature to form a thin layer of pipe that fits tightly with the old pipe. After the repair is completed, there is almost no loss in the cross section of the pipe, which can greatly improve its flow performance.

[0003] Before trenchless repair, it is necessary to prepare a lining hose impregnated with liquid thermosetting resin. The preparation process is as follows: first, the resin material and matrix raw materials such as curing agent in corresponding proportions need to be mixed and stirred, and the lining hose that has not been impregnated with resin (hereinafter referred to as "dry lining hose") needs to be vacuumed in advance; after these two preparatory tasks are completed, the mixed resin material is manually poured into the dry lining hose, and then it is rolled by a roller and other equipment to make the resin material evenly impregnated in the fiber layer of the dry lining hose; finally, a lining hose impregnated with liquid thermosetting resin (hereinafter referred to as "wet lining hose") that can be directly used for repair work can be obtained.

[0004] In this preparation process, most of the preparation processes are completed manually, such as the stirring of resin, the filling of dry lining hoses, etc., which is relatively labor-intensive for workers; secondly, the mechanical equipment used in the preparation process is relatively independent, and the connection between single equipment is relatively small, so manual work coordination between various equipment is required. For example, after the vacuumization of the dry lining hose is completed, manual work needs to be switched in time to carry out the filling. After the filling is completed, it is transferred to the rolling equipment for rolling. Relatively speaking, the overall coordination between equipment is not very convenient, which can easily cause work confusion and reduce work efficiency. In addition, it is extremely inconvenient to transfer work between multiple independent equipment. Utility Model Content

[0018] 1. The utility model uses mechanical equipment to complete several major processes involved in the production process of the lining hose by arranging a stirring device, a vacuum device and a rolling device. In actual production applications, the two ends of the dry lining hose are first connected to the injection pipe and the vacuum pipe respectively. When the stirring device is stirring, the injection pipe is closed, and the vacuum switch valve is opened at the same time to start the vacuum device. At this time, the dry lining hose can be vacuumed. After the stirring and vacuuming work are completed, the vacuum device is kept in the working state, and the injection pump on the injection pipe is turned on.

During this period, the vacuum device is in a continuous working state until one end of the hose connected to the vacuum pipe is close to the rolling device. At this time, the hose is removed from the vacuum pipe and the rolling is completed. In the entire production process, only a small number of workers are needed to guide the hose, which can reduce the overall labor intensity; secondly, the utility model integrates all devices in an integrated box, and the integrated box can be directly transferred as a whole by trucks and other transportation tools to adapt to changes in the workplace, which is convenient, fast, time-saving and labor-saving; at the same time, each device in the integrated box is uniformly controlled by the main controller, so that workers can easily dispatch various equipment to work and improve work efficiency.

[0019] 2. The utility model provides a heating strip on the inner wall of the shell of the stirring device, so that it can heat the resin material in the stirring device. Based on the inherent characteristics of the thermosetting resin material required in non-excavation repair, its own consistency will decrease when it is first heated, that is, its fluidity will increase, thereby reducing the difficulty of subsequent penetration of the resin material and the fiber layer in the dry lining hose, so that the two can be evenly mixed and contacted to ensure the subsequent curing performance of the resin material; secondly, a thermal insulation coating is coated on the outer wall of the shell to keep the stirring device in a constant temperature heating state to avoid changes in the chemical properties of the resin material caused by temperature changes.

[0020] 3. The utility model installs a vacuum sensor on the vacuum pipe, which is used to detect the vacuum condition in the vacuum pipe so as to control the operation of the vacuum device.

[0021] 4. The utility model repeatedly performs the rolling operation on the filled lining hose by setting a first rolling part and a second rolling part, wherein the first rolling part adopts an upper and lower double roller method, and its main function is to squeeze most of the resin material gathered at the front end of the lining hose to the rear end, so that the resin material filled in at one time can cover the fiber layer within the entire length of the lining hose; the second rolling part adopts a triangular three-roller method, and its rolling ability is stronger, and its main function is to make the resin material and the fiber layer in the lining hose penetrate evenly, thereby ensuring the stability and high quality of the subsequent resin after curing.

[0022] 5. The conveying mechanism of the utility model includes an inclined upward section and a horizontal section. When the inclined upward section transports the liner hose upward, the resin material in the tube will flow downward under the action of its own gravity, and at the same time, combined with the rolling of the first rolling part, it is ensured that the resin material can cover the entire length of the liner hose.

[0023] 6. The utility model installs a constant temperature device in the integrated box, and the constant temperature device works continuously to keep the temperature in the integrated box at about 40°C. At this temperature, the liquid resin material will not undergo a curing reaction and will not affect its own chemical properties. It is the most suitable temperature for storing hoses.

[0034] As a further solution in this embodiment, the rolling device 4 is sequentially provided with a first rolling part 41 and a second rolling part 42 along the conveying direction of the conveying mechanism 10, the first rolling part 41 includes a first driving roller 411 fixedly installed, the end of the first driving roller 411 is connected to a first driving motor 412, a first driven roller 413 movable up and down is provided above the first driving roller 411, and the gap between the first driving roller 411 and the first driven roller 413 is a hose passing area; the second rolling part 42 includes a second driving roller 42 fixedly installed 1 and the third driving roller 422, the ends of the second driving roller 421 and the third driving roller 422 are connected to the second driving motor 423, the second driving roller 421 and the third driving roller 422 are arranged horizontally at intervals, and a second driven roller 424 that can move up and down is provided above the second driving roller 421 and the third driving roller 422, the second driving roller 421, the third driving roller 422, and the second driven roller 424 are arranged in a triangle, and the gap between the second driving roller 421 and the third driving roller 422 and the second driven roller 424 is a hose passing area.

[0035] The first rolling part 41 and the second rolling part 42 in this embodiment can repeatedly perform the rolling operation on the filled lining hose, wherein the first rolling part 41 adopts the upper and lower double rollers, and its main function is to squeeze most of the resin material gathered at the front end of the lining hose to the rear end, so that the resin material filled in at one time can cover the fiber layer within the entire length of the lining hose; the second rolling part 42 adopts the triangular three-roller method, and its rolling ability is stronger. Its main function is to make the resin material and the fiber layer in the lining hose penetrate evenly, thereby ensuring the stability and high quality of the subsequent resin after curing.

[0036] As a further solution in this embodiment, the first driven roller 413 is installed on the conveying mechanism 10 through a first gantry 414, the first gantry 414 is perpendicular to the conveying surface of the conveying mechanism 10, and both ends of the first driven roller 413 are slidably connected to the first gantry 414; the second driven roller 424 is installed on the conveying mechanism 10 through a second gantry 425, the second gantry 425 is perpendicular to the conveying surface of the conveying mechanism 10, and both ends of the second driven roller 424 are slidably connected to the second gantry 425.

The use of unpowered rollers 102 can save equipment costs to a great extent. The conveying power of the lining hose on the conveying mechanism 10 mainly comes from the rotation of each powered roller. Therefore, during the production process, it is necessary to manually move the end of the dry lining hose to between the upper and lower rollers of the first rolling part 41, and use the rotation of the first active roller 411 to drive the lining hose forward and achieve the first rolling.
