Description

Technical Field

[0001] This invention relates to the field of pipeline installation equipment technology, specifically to a modular pipeline construction splicing device and construction process. Background Technology

[0002] Pipelines are widely used as core components for fluid transport in many fields such as municipal engineering, building water supply and drainage, and farmland irrigation. Among them, commonly used pipes such as PVC pipes and PE pipes are mostly connected by socket joints. The two ends of such pipes are clearly distinguished, namely the spigot and the socket. The spigot is the insertion end with a slightly smaller outer diameter, and the socket is the sleeve end with a slightly larger inner diameter. During installation, the spigot must be accurately inserted into the socket to complete the splicing and assembly of the pipes. In the current actual construction process, the installation of such socket joint pipes mostly relies on manual operation, usually requiring at least two workers to work together. One worker holds the fixed pipe socket to ensure its stability, while the other worker holds the spigot of the pipe to be connected, aligns it with the socket, and slowly inserts it to achieve the connection of the two pipes.

[0003] However, the existing technology has the following problems:

[0004] The existing manual installation method relies entirely on the experience and feel of the workers, lacks a precise positioning and guiding mechanism, and the coordination between two workers is difficult to guarantee, which can easily lead to docking deviations, resulting in eccentricity and skewing problems, affecting the installation quality. At the same time, the manual splicing method is labor-intensive and has low construction efficiency, making it difficult to meet the needs of large-scale modular construction. Summary of the Invention

[0005] The purpose of this invention is to provide a modular pipeline construction splicing device and construction process to solve the above-mentioned problems, and to overcome the defects of existing technologies that easily cause eccentricity and skewing when manually splicing pipelines, as detailed below.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The modular construction and splicing device for pipelines provided by this invention includes two pairs of semicircular rings, each pair of which is connected by a hinge. One pair of semicircular rings is connected to a set of smooth rods, and the other pair of semicircular rings is slidably sleeved on the two sets of smooth rods. The semicircular rings are provided with a clamping mechanism for clamping the outer wall of the pipeline. The device also includes a stepping mechanism for driving the two pairs of semicircular rings to move closer to each other to achieve pipeline docking. The device also includes an adhesive application component for applying adhesive to the pipeline docking joint.

[0008] Preferably, each pair of semicircular rings is provided with a fastener, which includes a rectangular pin. Two wedges are slidably embedded in the bottom of the rectangular pin. An inner rod is vertically slidably connected inside the rectangular pin. Two pull rods are hinged to the bottom of the inner rod. The two pull rods are respectively hinged to the two wedges. A pull ring is provided at the top of the inner rod. The inner rod drives the two wedges to retract into the rectangular pin through the two pull rods. The two semicircular rings in the same pair are respectively provided with square holes that match the position. After the rectangular pin is inserted into the two square holes, the two semicircular rings are fastened together.

[0009] Preferably, the clamping mechanism includes two connecting blocks, which are slidably mounted on a semicircular ring. A pressure block is connected to the connecting block by a spring. A pair of support rods are hinged between the pressure block and the connecting block. The end of the support rod on the semicircular ring near the pressure block is inclined toward the other pair of semicircular rings.

[0010] Preferably, the clamping mechanism further includes a grooved plate, which is rotatably mounted on a semi-circular ring. Two arc-shaped grooves are formed on the grooved plate. A sliding shaft is connected to the connecting block. The two arc-shaped grooves are slidably connected to the two sliding shafts respectively. A handle is connected to the grooved plate. When the grooved plate moves in a circular motion, it drives the two sliding shafts to move away from or towards the center of the semi-circular ring through the arc-shaped grooves.

[0011] Preferably, a slide rod is slidably connected to the handle, a pressure plate is connected to the slide rod, a set of first limiting grooves are opened on the semi-circular ring, a first limiting rod is hinged to the groove plate, a return coil spring is provided at the hinge fulcrum of the first limiting rod, one end of the first limiting rod slides in contact with the slide rod, and the other end of the first limiting rod is embedded in one of the first limiting grooves.

[0012] Preferably, the stepping mechanism includes two threaded plates and two slides. The two threaded plates are respectively fixedly mounted on one pair of semicircular rings, and the two slides are respectively fixedly mounted on the other pair of semicircular rings. Semicircular nut seats are rotatably connected to the two slides. The inner sides of the two semicircular nut seats are provided with matching continuous internal threads. Both threaded plates are provided with external threads that match the internal threads. When the two semicircular nut seats move in a circular motion, they can drive the two pairs of semicircular rings to move closer or further apart through the two threaded plates. The outer wall of the semicircular nut seats is provided with multiple handles.

[0013] Preferably, a second limiting rod is hinged to the semi-circular nut seat, and a second limiting groove is provided on the slide block, with the second limiting rod embedded in the second limiting groove.

[0014] Preferably, the adhesive application assembly includes an adhesive cartridge mounted on one of the threaded plates, a nozzle connected to the bottom of the adhesive cartridge, and an air cylinder mounted on the top of the adhesive cartridge.

[0015] Preferably, the adhesive application assembly further includes two semi-circular slide rails, which are respectively connected to the inner sides of two threaded plates. A brush is slidably connected to the semi-circular slide rail, and an arc-shaped return spring is provided between the brush and the interior of the semi-circular slide rail. A pull rope is connected to the brush, and the end of the pull rope away from the brush extends to the outside of the semi-circular slide rail.

[0016] The modular construction and splicing process for pipelines includes the following steps:

[0017] Step 1: Fitting and closing: Open the two pairs of semicircular rings, fit them onto the outer walls of the two pipes to be connected, and then close them.

[0018] Step 2: Fastening and fixing. Insert the rectangular pin into the square hole and use the wedge to fasten and fix each pair of semicircular rings.

[0019] Step 3: Clamping and limiting, turn the handle to adjust the groove plate so that the pressure blocks on the two pairs of semi-circular rings clamp the two pipes respectively;

[0020] Step 4: Apply the adhesive evenly, press the air pump, spray the adhesive through the nozzle into the pipe inlet, and pull the pull rope to spread it evenly with a brush.

[0021] Step 5: Once the connection is complete, rotate the semi-circular nut seat. The stepping mechanism will drive the two pairs of semi-circular rings closer together to complete the pipe connection.

[0022] Step Six: Disassemble the device. After docking, unlock the fasteners and limiting structure, open the semi-circular ring and remove the device.

[0023] The beneficial effects are:

[0024] 1. This modular pipeline splicing device, through the cooperation of the clamping mechanism and the stepping mechanism, ensures that the two pairs of semicircular rings maintain coaxiality under the guidance of the smooth rod. The pressure block achieves stable clamping of the pipeline through the linkage of the support rod, connecting block, sliding shaft and grooved plate. The threaded plate, sliding seat and semicircular nut seat of the stepping mechanism cooperate to convert the rotational motion into axial displacement, smoothly drive the pipeline to connect, effectively avoid the eccentricity and skewing problems of manual splicing, improve the pipeline splicing accuracy, and at the same time, it is convenient and labor-saving to operate, reducing the labor intensity of workers.

[0025] 2. This modular pipe splicing device, through the setting of the adhesive application component, allows workers to spray adhesive onto the pipe joint by pressing the air cylinder and pulling the rope before connecting the pipes. Two brushes then spread the adhesive evenly, achieving a semi-automatic adhesive application effect. This reduces the number of manual adhesive application steps, allowing workers to focus on operating the two pairs of semi-circular rings and the stepping mechanism, further simplifying the installation process.

[0049] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0050] Please see Figure 1 - Figure 9 In one embodiment:

[0051] The modular pipeline construction splicing device includes two pairs of semicircular rings 1, each pair connected by hinges. Each pair of semicircular rings 1 can open and close. When open, it is easy to fit onto the outer wall of the pipeline; when closed, it forms a closed ring structure. One pair of semicircular rings 1 is connected to a set of smooth rods 3, and the other pair of semicircular rings 1 is slidably fitted onto the two sets of smooth rods 3. The two pairs of semicircular rings 1 are connected as a whole by the smooth rods 3, ensuring coaxiality. Workers can synchronously open and close the two pairs of semicircular rings 1 by manipulating the smooth rods 3, allowing the sliding... A pair of semicircular rings 1 fitted onto the optical rod 3 can slide along the two sets of optical rods 3 towards or away from the other pair of semicircular rings 1. The semicircular rings 1 are provided with clamping mechanisms 2 for clamping the outer wall of the pipe. Each pair of semicircular rings 1 is provided with a pair of clamping mechanisms 2. The two pairs of clamping mechanisms 2 clamp the two pipes that need to be connected respectively. It also includes a stepping mechanism 5. The stepping mechanism 5 is used to drive the two pairs of semicircular rings 1 to move closer to each other so as to realize the pipe connection. After the two pairs of clamping mechanisms 2 clamp the two pipes respectively, the stepping mechanism 5 drives the two pairs of semicircular rings 1 to move closer to each other, thereby prompting the two pipes to complete the connection.

[0052] Furthermore, each pair of semicircular rings 1 is provided with a fastener 4, which includes a rectangular pin 41. Two wedges 44 are slidably embedded in the bottom of the rectangular pin 41. An inner rod 42 is vertically slidably connected inside the rectangular pin 41. Two pull rods 43 are hinged to the bottom of the inner rod 42. The two pull rods 43 are respectively hinged to the two wedges 44. A pull ring is provided at the top of the inner rod 42. When the inner rod 42 is opened, the two wedges 44 are driven to retract into the rectangular pin 41 through the two pull rods 43. The two semicircular rings 1, which are in the same pair, are respectively provided with square holes that match their positions. After the rectangular pin 41 is inserted into the two square holes, the two semicircular rings 1 are fastened together. A part of the wedge 44 protrudes from the bottom outer wall of the rectangular pin 41, and the bottom of the protruding part is provided with an angle. The two wedges 44 A spring is provided between the two rectangular pins 41. When the rectangular pin 41 is inserted, the two wedges 44 are pushed into the rectangular pin 41 by the counterforce of the edge of the square groove. After the rectangular pin 41 is inserted into place, the two wedges 44 are disengaged from the square groove and rebound outward by the spring force. At this time, the wedges 44 can abut against the bottom edge of the square groove below, thereby securing the two semicircular rings 1 together. When disassembling, pull the top ring of the inner rod 42 upward, and the inner rod 42 slides vertically upward. The two hinged pull rods 43 generate an inward pulling force on the wedges 44, causing the two wedges 44 to retract into the rectangular pin 41. At this time, the rectangular pin 41 can be smoothly pulled out from the square hole. This achieves the technical effect of quickly closing and fastening the two pairs of semicircular rings 1 using the fastener 4, and the operation is relatively convenient.

[0053] Furthermore, the clamping mechanism 2 includes two connecting blocks 21, which are slidably mounted on the semicircular ring 1. A pressure block 23 is connected to the connecting block 21 via a spring. The contact surface between the pressure block 23 and the pipe is provided with anti-slip ribs. A pair of support rods 22 are hinged between the pressure block 23 and the connecting block 21. The pair of support rods 22 are parallel and form an oblique support structure. The end of the support rod 22 on the semicircular ring 1 near the pressure block 23 is inclined towards the other pair of semicircular rings 1. The connecting block 21 is slidably mounted along the radial direction of the semicircular ring 1. After the two pairs of semicircular rings 1 are opened and closed, they are fitted onto the two pipes. Taking one pipe as an example, the pressure block 23 on the semicircular ring 1 can maintain contact with the outer wall of the pipe using the elastic force of the spring. At this time, the ends of the support rods 22 on both pairs of semicircular rings 1 near the pressure block 23 are inclined towards the connection point of the two pipes. Figure 3 As shown, when the pressure blocks 23 on both sides simultaneously apply force towards the center, the pressure blocks 23 exert force on the outer wall of the pipe using the friction between themselves and the pipe. A pair of support rods 22 provide oblique support, thereby increasing the pressure of the pressure blocks 23 on the outer wall of the pipe. Therefore, the greater the horizontal force exerted by the pressure blocks 23, the greater the pressure on the outer wall of the pipe, and the greater the friction. Consequently, when the pressure blocks 23 on the two pairs of semicircular rings 1 approach each other, the pressure blocks 23 use friction to drive the pipes they contact to move along the pipe axis, ultimately pushing the two... Pipe docking enables the insertion of two pipe interfaces. Due to the high coaxiality of the two pairs of semi-circular rings 1, the two pipes can also maintain a high degree of coaxiality when docking, making the insertion action smoother. Compared with manual pipe splicing, the operation is more convenient and less labor-intensive, ensuring the splicing accuracy of the pipes. The cooperation of the pressure block 23, the support rod 22 and the spring allows the pressure block 23 to adapt to the clamping requirements of various pipe specifications. When docking pipes within the applicable range, there is no need to change the device, thus expanding the scope of application.

[0054] In addition, the clamping mechanism 2 also includes a grooved plate 25, which is rotatably mounted on the semi-circular ring 1. Two arc-shaped grooves are formed on the grooved plate 25. A sliding shaft 24 is connected to the connecting block 21. The two arc-shaped grooves are slidably connected to the two sliding shafts 24 respectively. A handle 26 is connected to the grooved plate 25. When the grooved plate 25 moves in a circular motion, it drives the two sliding shafts 24 to move away from or towards the center of the semi-circular ring 1 through the arc-shaped grooves. The grooved plate 25 is semi-circular in shape, and a semi-circular guide rail is provided on the semi-circular ring 1. The grooved plate 25 is slidably mounted within this guide rail. When the operator rotates the grooved plate 25 through the handle 26, the arc-shaped grooves on the grooved plate 25 apply a force to the sliding shafts 24, forcing the sliding shafts 24 to slide along the arc-shaped grooves. The sliding shafts 24 and the connecting block 21 can only slide radially along the semi-circular ring 1. Therefore, when the arc-shaped grooves move, they apply a force to the sliding shafts 24 using their edges, forcing the sliding shafts 24 to drive the connecting block 21 to move away from or towards the center of the semi-circular ring 1. In this embodiment, as shown... Figure 4As shown, when the groove 25 rotates clockwise, the connecting block 21 moves away from the center of the semicircular ring 1. When the groove 25 rotates counterclockwise, the connecting block 21 moves closer to the center of the semicircular ring 1. When the connecting block 21 moves, the pressure block 23 moves synchronously through the support rod 22 and the spring. Thus, the technical effect of adjusting the distance between the pressure block 23 and the center of the semicircular ring 1 is achieved. When connecting pipes, the operator can adjust the distance between the pressure block 23 and the outer wall of the pipe according to the outer diameter of the pipe, thereby ensuring that the pressure block 23 can maintain effective contact with the outer wall of the pipe. Combined with the elastic adaptability of the pressure block 23 itself, the adaptability range of the clamping mechanism 2 is further expanded to meet the connection operations of various pipes.

[0055] It is worth noting that a slide rod 27 is slidably connected to the handle 26, and a pressure plate 28 is connected to the slide rod 27. A set of first limiting grooves 210 are provided on the semi-circular ring 1, and a first limiting rod 29 is hinged to the slotted plate 25. A return coil spring is provided at the hinge fulcrum of the first limiting rod 29. One end of the first limiting rod 29 is in sliding contact with the slide rod 27, and the other end of the first limiting rod 29 is embedded in one of the first limiting grooves 210. A set of first limiting grooves 210 are evenly distributed along the edge of the semi-circular ring 1. When the slotted plate 25 needs to be rotated, while holding the handle 26, press the pressure plate 28 with your finger, so that the pressure plate 28 drives the slide rod 27 to move closer to the first limiting rod 29. The fulcrum is located between its two ends. Therefore, when the end of the first limiting rod 29 that contacts the pressure plate 28 is pressed down, the end of it that is embedded in the first limiting groove 210 will lift up and disengage from the first limiting groove 210. At this time, the operator can flexibly rotate the groove plate 25. When the groove plate 25 is rotated to the appropriate angle, the pressure plate 28 is released, and the first limiting rod 29 is reset by the elastic force of the reset coil spring, so that the first limiting rod 29 is re-embedded in the nearest first limiting groove 210, thereby achieving the angle limiting effect of the groove plate 25. After the angle of the groove plate 25 is limited, it can maintain the position of the sliding shaft 24 that is currently in contact with it, thereby ensuring the stability of the position of the connecting block 21 and the pressure block 23, and maintaining clamping stability during the docking operation.

[0056] It is worth noting that the stepping mechanism 5 includes two threaded plates 51 and two slides 52. The two threaded plates 51 are respectively fixedly mounted on one pair of semicircular rings 1, and the two slides 52 are respectively fixedly mounted on the other pair of semicircular rings 1. Semicircular nut seats 53 are rotatably connected to the two slides 52. The inner sides of the two semicircular nut seats 53 are provided with matching continuous internal threads. Both threaded plates 51 are provided with external threads that match the internal threads. When the two semicircular nut seats 53 move in a circular motion, they can drive the two pairs of semicircular rings 1 to move closer or further apart through the two threaded plates 51. The outer wall of the semicircular nut seats 53 is provided with multiple handles. When one pair of semicircular rings 1 opens, the two semicircular nut seats 53 separate. After the semicircular rings 1 close, the two semicircular nut seats 53 also close. The slides 52 are provided with semicircular slide rails that are open at both ends. When the two slides 52 close with the semicircular rings 1, the two semicircular slide rails are spliced ​​into a complete annular slide rail. After the two semicircular nut seats 53 close, they can... The semicircular nut seat 53 can move circumferentially within the annular slide rail. The operator rotates the handle to turn the semicircular nut seat 53. During this circumferential movement, each semicircular nut seat 53 alternately enters the two slide seats 52 and continues to move in a circular motion. After the two semicircular nut seats 53 close, their internal threads also interlock to form a complete internal thread, while the two threaded plates 51 form an open external thread. At this time, the external threads of the two threaded plates 51 and the internal threads formed by the two semicircular nut seats 53 form a threaded transmission pair. Therefore, when the handle is turned to turn the semicircular nut seat 53, the threaded engagement converts the circumferential rotational motion into axial linear displacement between the threaded plate 51 and the semicircular nut seat 53. In this embodiment, when the semicircular nut seat 53 is rotated clockwise, the threaded plate 51 drives the connected semicircular ring 1 to move closer to the semicircular nut seat 53; when the semicircular nut seat 53 is rotated counterclockwise, the threaded plate 51 drives the connected semicircular ring 1 to move away from the semicircular nut seat 53. Therefore, as... Figure 7 As shown, when the operator rotates the two semi-circular nut seats 53 clockwise, the threaded transmission pair drives the pair of semi-circular rings 1 on the right to move to the left and closer to the semi-circular rings 1 on the left. This causes the clamping mechanism 2 on the right to move the pipe on the right to the left and connect with the pipe on the left, thus achieving pipe connection. After connection, rotating the semi-circular nut seats 53 counterclockwise causes the clamping mechanism 2 on the right to move to the right. At this time, refer to... Figure 3 When the pressure block 23 on the right moves to the right along the outer wall of the pipe, the support rod 22 on the pressure block 23 can swing upward, thus losing its oblique support force. When the pressure block 23 moves to the right, it only rubs slightly along the outer wall of the pipe and does not generate a clamping force on the pipe, causing the already connected pipe to move to the right.

[0057] It is worth mentioning that a second limiting rod 54 is hinged to the semicircular nut seat 53, and a second limiting groove 55 is opened on the slide 52. The second limiting rod 54 is embedded in the second limiting groove 55. The second limiting rod 54 and the second limiting groove 55 actually play a positioning role. After the docking is completed, when it is necessary to open the two pairs of semicircular rings 1, rotate the semicircular nut seat 53 so that the second limiting rod 54 is aligned with the second limiting groove 55. This means that the semicircular nut seat 53 has been completely returned to the slide 52 and the two semicircular nut seats 53 do not interfere with each other. At this time, move the second limiting rod 54 to make it swing and embed into the second limiting groove 55, and the semicircular rings 1 can be opened.

[0058] Please see Figure 1 , Figure 10 , Figure 11 In another embodiment:

[0059] It also includes an adhesive application assembly 6 for applying adhesive to pipe joints. The adhesive application assembly 6 includes an adhesive container 61, which is installed on one of the threaded plates 51. The bottom of the adhesive container 61 is connected to a nozzle 62, and the top of the adhesive container 61 is equipped with an air cylinder 63. The adhesive container 61 contains adhesive for pipe bonding. When two pipes are joined, the two ends of the pipes are a socket and a spigot, respectively. During installation, the adhesive container 61 is positioned above the spigot. After the semi-circular ring 1 is fitted onto the outer wall of the pipe and locked in place, the air cylinder 63 is pressed. The air cylinder 63 is pressurized and introduces compressed air into the adhesive container 61, increasing the air pressure inside the adhesive container 61. This causes the adhesive container 61 to use the positive pressure principle to evenly squeeze the adhesive out of the nozzle 62 and accurately spray it onto the pipe spigot, achieving the technical effect of quantitative adhesive spraying.

[0060] In addition, the adhesive application assembly 6 also includes two semi-circular slide rails 64, which are respectively connected to the inner sides of the two threaded plates 51. A brush 65 is slidably connected to each semi-circular slide rail 64, providing a semi-circular sliding trajectory guide for the brush 65. An arc-shaped return spring is provided between the brush 65 and the interior of the semi-circular slide rail 64. A pull rope 66 is connected to the brush 65, with one end of the pull rope 66 extending to the outside of the semi-circular slide rail 64. After the nozzle 62 sprays adhesive, pulling the two pull ropes 66 causes the semi-circular slide rail 64 to provide annular sliding guidance for the brush 65. Pulling the pull ropes 66 enables the brush 65 to slide along the entire length of the semi-circular slide rail 64, evenly spreading the adhesive sprayed by the nozzle 62 onto the pipe joint surface and eliminating adhesive accumulation. When the gap is filled, after releasing the pull rope 66, the brush 65 automatically resets under the action of the arc-shaped return spring and applies the adhesive again. During the reciprocating motion of the two brushes 65, the outer wall of the inlet can be completely covered, so that the adhesive is evenly applied to the pipe inlet, avoiding local adhesive accumulation and local lack of adhesive. With the setting of the adhesive application component 6, before connecting the pipe, the operator can press the air cylinder 63 and pull the pull rope 66 to make the nozzle 62 spray the adhesive onto the pipe inlet, and the two brushes 65 apply the adhesive evenly. This achieves the technical effect of semi-automatic adhesive application, reduces the manual adhesive application operation steps, and allows the operator to focus on the engagement of the two pairs of semi-circular rings 1 and the stepping mechanism 5, further simplifying the installation operation.

[0061] In another embodiment, the modular pipeline construction and splicing process, using the modular pipeline construction and splicing device described in the above embodiments, further includes the following steps:

[0062] Step 1: Fitting and closing: Open the two pairs of semicircular rings 1, fit them onto the outer walls of the two pipes to be connected, and then close them;

[0063] Step 2: Fastening and fixing. Insert the rectangular pin 41 into the square hole and use the wedge block 44 to fasten and fix each pair of semicircular rings 1.

[0064] Step 3: Clamping and limiting, rotate handle 26 to adjust groove 25 so that the pressure blocks 23 on the two pairs of semi-circular rings 1 clamp the two pipes respectively;

[0065] Step 4: Apply the adhesive evenly, press the air pump 63, spray the adhesive into the pipe inlet through the nozzle 62, and pull the pull rope 66 to spread it evenly with the brush 65.

[0066] Step 5: After docking is complete, rotate the semi-circular nut seat 53, and drive the two pairs of semi-circular rings 1 to approach each other through the stepping mechanism 5 to complete the pipe docking;
