Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically to an auxiliary device for pipeline laying in municipal and building engineering. Background Technology

[0002] Hot fusion welding refers to a connection method between non-metallic materials, achieved by heating the material to its (liquid) melting point. It is widely used in connecting new types of pipes and fittings such as PP-R pipes, PB pipes, PE-RT pipes, metal composite pipes, and flexible vector aluminum alloy lined composite pipe systems. In municipal and building engineering pipeline laying, hot fusion welding is a key process for connecting pipes.

[0003] Based on the above, the inventors have discovered the following problems: When performing hot-melt butt welding on existing pipelines, the connection is often made manually. The key to hot-melt butt welding lies in the precise alignment and tight fit of the pipeline interfaces to ensure welding strength and sealing. However, during manual operation, factors such as worker experience, physical strength, and the on-site environment make it difficult to guarantee the depth, angle, and coaxiality of the pipe insertion, ultimately affecting the strength and sealing of the pipeline connection.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide an auxiliary device for pipeline laying in municipal and building engineering, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary device for laying pipelines in municipal and building engineering projects, in order to solve the problem mentioned in the background art that when existing pipelines are hot-melt butt-jointed, they are often joined by manual insertion. During manual operation, due to factors such as worker experience, physical strength and site environment, it is difficult to guarantee the depth, angle and coaxiality of the pipeline insertion, which ultimately affects the strength and sealing of the pipeline connection.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A pipeline laying auxiliary device for municipal and building engineering includes a traction mechanism and a fixing mechanism. The traction mechanism includes a fixed rod, a traction rod is slidably inserted inside the fixed rod, a screw is rotatably connected to one side of the fixed rod, and a threaded cylinder is inserted into one end of the traction rod. The screw and the threaded cylinder are threadedly connected. The fixing mechanism includes a pair of mounting frames, which are respectively disposed on one side of the bottom end of the fixed rod and the traction rod. A buffer block is fixedly installed at the bottom end of the mounting frame. Clamping arms are provided on both sides of the mounting frame, and a clamping block is fixedly installed at the bottom end of the facing surface of each pair of clamping arms.

[0008] Furthermore, a servo motor is fixedly installed on one side of the inside of the fixed rod, and a worm gear is sleeved on the output end of the servo motor.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the servo motor provides power to the screw, and through the meshing transmission of the worm and worm wheel, the rotational motion of the motor is converted into the rotation of the screw, realizing the automated control of the extension and retraction of the traction rod, which is convenient to operate and has stable power.

[0010] Furthermore, a worm gear is fitted onto one end of the screw, and the worm gear meshes with the worm.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the meshing of the worm gear and the worm forms a speed reduction transmission. By utilizing the self-locking characteristics of the worm gear and the worm, it can be automatically locked after the traction rod is adjusted to the designated position, preventing the expansion structure from loosening due to external forces during pipeline traction and ensuring docking accuracy.

[0012] Furthermore, each of the mounting brackets has a connector slidably mounted inside. Both ends of the connector are rotatably connected to a first link and a second link. The other ends of the first link and the second link are hinged to one end of the clamping arm via a pin.

[0013] The beneficial effect of adopting the above-mentioned further solution is that when the connector slides, the clamping arm rotates around the mounting frame through the hinge transmission of the first and second connecting rods, thereby realizing the opening and closing action of the clamping block; the connecting rod structure can transmit power evenly, ensuring that the clamping arms on both sides move synchronously and stably clamp pipes of different diameters.

[0014] Furthermore, both ends of the mounting bracket are rotatably connected to a third link, and the other end of the third link is hinged to the center of the first link via a pin.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the third link is hinged to the first link to form a four-bar linkage, which provides support and guidance during the opening and closing of the clamping arm, enhances the stability of the clamping structure, avoids the clamping arm from shifting due to uneven force, and ensures that the pipeline is firmly fixed.

[0016] Furthermore, the fixing mechanism also includes a pair of pneumatic telescopic rods, which are respectively inserted into one end of the fixing rod and the traction rod, and the bottom end of the pneumatic telescopic rod is connected to the top end of the connector.

[0017] The advantages of adopting the above-mentioned further solution are that the pneumatic telescopic rod drives the connecting parts to move up and down, and controls the opening and closing of the clamping arm through the linkage mechanism to realize the automatic clamping and release of the pipeline. Moreover, the clamping force can be precisely controlled by adjusting the air pressure to avoid damaging the pipeline surface.

[0018] Furthermore, a V-shaped groove is provided on one side of both the buffer block and the pair of clamping blocks, and a rubber pad is provided on the inner wall of both the buffer block and the pair of clamping blocks.

[0019] The beneficial effects of adopting the above-mentioned further solutions are that the V-groove design fits tightly against the outer wall of the pipe, which can meet the clamping requirements of circular pipes. The rubber pad increases friction to prevent the pipe from sliding, while buffering the mechanical stress during the clamping process, protecting the pipe from damage, and improving the versatility and reliability of the fixing mechanism.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: This auxiliary device for pipeline laying in municipal and construction engineering has a traction mechanism that, through the threaded engagement of a screw and a threaded cylinder, can adjust the relative length of the fixing rod and the traction rod to adapt to the traction needs of pipelines with different laying distances; the clamping arm and clamping block of the fixing mechanism can fix both ends of the pipeline, and work with the traction mechanism to connect two sections of the pipeline; the buffer block provides support when the fixing mechanism clamps and fixes the pipeline; the servo motor provides power to the screw, and the rotation of the motor is transmitted through the meshing of the worm gear and worm wheel. The pneumatic telescopic rod is converted into the rotation of the screw, realizing the automated control of the extension and retraction of the traction rod. It is easy to operate and has stable power. When the connecting part slides, the first and second connecting rods are hinged to drive the clamping arm to rotate around the mounting frame, realizing the opening and closing action of the clamping block. The connecting rod structure can transmit power evenly, ensuring that the clamping arms on both sides move synchronously and stably clamp pipes of different diameters. The pneumatic telescopic rod drives the connecting part to move up and down. The opening and closing of the clamping arm is controlled by the connecting rod mechanism to realize the automated clamping and release of the pipe. The clamping force can be precisely controlled by adjusting the air pressure to avoid damaging the pipe surface. Attached Figure Description

The buffer block 203 provides support when the fixing mechanism 2 clamps and fixes the pipeline.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-4A servo motor 103 is fixedly installed on one side of the inner side of the fixed rod 101. A worm gear 105 is sleeved on the output end of the servo motor 103, and a worm wheel 104 is sleeved on one end of the screw 106. The worm wheel 104 and the worm gear 105 mesh with each other. The servo motor 103 provides power to the screw 106. Through the meshing transmission of the worm gear 105 and the worm wheel 104, the rotational motion of the motor is converted into the rotation of the screw 106, realizing the automated control of the extension and retraction of the traction rod 102. The operation is convenient and the power is stable. The meshing of the worm wheel 104 and the worm gear 105 forms a reduction transmission. Utilizing the self-locking characteristics of the worm gear, the traction rod 102 can be automatically locked after being adjusted to the designated position, preventing the extension and retraction structure from loosening due to external forces during pipeline traction and ensuring docking accuracy.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-4The mounting bracket 201 has a connector 208 slidably mounted inside. Both ends of the connector 208 are rotatably connected to a first connecting rod 209 and a second connecting rod 207. The other ends of the first connecting rod 209 and the second connecting rod 207 are hinged to one end of the clamping arm 204 via a pin. Both ends of the mounting bracket 201 are rotatably connected to a third connecting rod 205. The other end of the third connecting rod 205 is hinged to the center of the first connecting rod 209 via a pin. The fixing mechanism 2 also includes a pair of pneumatic... A pair of pneumatic telescopic rods 202 are respectively inserted into one end of the fixed rod 101 and the traction rod 102. The bottom end of the pneumatic telescopic rod 202 is connected to the top end of the connector 208. A V-shaped groove is opened on one side of the buffer block 203 and the pair of clamping blocks 206. Rubber pads are provided on the inner walls of the buffer block 203 and the pair of clamping blocks 206. When the connector 208 slides, the clamping arm 20 is driven by the hinge transmission of the first connecting rod 209 and the second connecting rod 207. 4. Rotating around the mounting bracket 201, the clamping block 206 opens and closes. The linkage structure can evenly transmit power, ensuring that the clamping arms 204 on both sides move synchronously and stably clamp pipes of different diameters. The third linkage 205 is hinged to the first linkage 209 to form a four-bar linkage mechanism, which provides support and guidance during the opening and closing of the clamping arms 204, enhances the stability of the clamping structure, avoids the clamping arms 204 from shifting due to uneven force, and ensures that the pipe is firmly fixed. The pneumatic telescopic rod 202 drives the connecting piece 208 to move up and down. The opening and closing of the clamping arms 204 is controlled by the linkage mechanism to realize the automatic clamping and release of the pipe. The clamping force can be precisely controlled by adjusting the air pressure to avoid damaging the pipe surface. The V-groove design fits tightly with the outer wall of the pipe and can adapt to the clamping requirements of round pipes. The rubber pad increases friction to prevent the pipe from sliding and buffers the mechanical stress during the clamping process, protecting the pipe from damage and improving the versatility and reliability of the fixing mechanism 2.

[0032] Specifically, the working principle of this auxiliary device for pipeline laying in municipal and construction engineering is as follows: In use, the servo motor 103 first drives the worm gear 105 to rotate, which in turn drives the screw 106 to rotate via the worm wheel 104 reduction transmission. The threaded engagement between the screw 106 and the threaded cylinder 107 causes the traction rod 102 to extend and retract within the fixed rod 101. After adjusting to the appropriate laying distance for the two pipeline sections, the position is locked using the self-locking characteristic of the worm gear. Subsequently, the pneumatic telescopic rod 202 extends, pushing the connecting piece 208 downwards, through the first... The four-bar linkage consisting of link 209, second link 207 and third link 205 drives the clamping arms 204 on both sides to rotate around the mounting frame 201, so that the V-groove of the clamping block 206 fits against the outer wall of the pipe. The rubber pad provides buffering and friction, fixing both ends of the pipe to the mounting frame 201 of the fixing rod 101 and the traction rod 102 respectively. The V-groove of the buffer block 203 is used to support the traction mechanism 1. After the fixing is completed, the traction mechanism 1 pulls or pushes the pipe through the telescopic action to realize the connection of the two pipe sections.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, this application will not explain the control method and circuit connection in detail.
