Description

Technical Field

[0001] The present invention relates to the technical field of communication pipeline laying, and in particular to a communication pipeline laying device with a supporting function. Background Art

[0002] Communication pipeline engineering refers to the construction of pipelines specifically for the purpose of building communication lines in urban areas, so as to avoid building electric poles and lines on both sides of the streets to ensure the beauty of the urban area. At present, when laying communication pipelines, trenches are usually dug on the ground to place the pipelines, and then the pipelines are filled with soil to achieve the laying of communication pipelines. Optical cables are laid in the pipelines, and the pipelines play a protective role for the optical cables.

[0003] Communication pipelines are usually plastic pipes of specified lengths. When laying, multiple sections of plastic pipes need to be placed in the excavated trench in sequence, and then the ends of adjacent plastic pipes are connected and fixed through connecting devices to complete the pipeline laying. To improve the efficiency of pipeline laying, on-site construction workers will use some lifting equipment to lift the pipeline, lift the pipeline into the trench and align it with the end of the installed pipeline in the trench.

[0004] After searching, the Chinese patent with publication number: CN119813042A discloses a laying device and laying method for communication pipes, which includes a guide block, etc., a guide groove is opened inside the guide block, and lifting rings are symmetrically fixed on both sides of the top of the guide block. The lifting rings of the guide block are used to provide a lifting interface for an operating machine such as a crane. The first boom is fixed to one side of the lower part of the guide block, and the sliding block is slidably connected to the other side of the lower part of the guide block through the guide groove. The second boom is installed on the sliding block, and the first boom and the second boom are horizontally distributed.

[0005] Based on the above search and combined with actual problems, it was found that: the device cannot position the hoisted pipe to be installed in actual use. Since the hoisted pipe to be installed will swing in the air, the hoisted pipe to be installed cannot be accurately moved to the end of the installed pipe in the groove, resulting in the hoisted pipe to be installed and the installed pipe cannot maintain coaxiality. The ends of the two pipe sections cannot be completely fitted, resulting in misalignment and gaps, which increases the difficulty of docking the two pipe sections.

[0034] The present invention provides a communication pipeline laying device with a supporting function through improvement. The technical solution of the present invention is:

[0035] like Figures 1 to 8As shown, the embodiment of the present invention provides a communication pipeline laying device with a supporting function, including a support pipe 1, which is movably connected to a driving vehicle body through a supporting mechanism, two driving motors 3 are installed on both sides of the driving chassis 2, and the driving ends of the two driving motors 3 are fixed with driving wheels 4, and the side walls of the support pipe 1 are slidably connected with multiple inner support plates 101, one end of each inner support plate 101 is fixed with a fixed support plate 102, and the other end of each inner support plate 101 is movably provided with a movable support plate 103, the interior of each movable support plate 103 is provided with an adsorption mechanism, and the outer side of each movable support plate 103 is provided with a rubber pad 208; it also includes a telescopic mechanism for driving the multiple inner support plates 101 to extend and retract, and a propulsion mechanism for driving the multiple movable support plates 103 to move; the telescopic mechanism includes multiple slide plates 104 fixed on one side of each inner support plate 101, and a screw 106 rotatably arranged on the inner side of the support pipe 1, and the multiple slide plates 104 are provided with inclined slide grooves 105, and the outer side of the screw 106 is threadedly connected There is an internal threaded sleeve 107, and the outer side of the internal threaded sleeve 107 is provided with a plurality of sliding pins 108 respectively slidingly adapted with each inclined slide groove 105. A motor 110 is installed at one end of the inner side of the support tube 1 for driving the screw 106 to rotate, and a screw bracket 113 is fixed at the end position of the screw 106 on the inner side of the support tube 1. The end of the screw 106 is rotatably connected to the inside of the screw bracket 113, and a sliding pin bracket 113 is fixed at the position of each sliding pin 108 on the outer side of the internal threaded sleeve 107. 09, multiple sliding pins 108 are respectively passed through and rotatably connected to the inside of each sliding pin bracket 109; the propulsion mechanism includes multiple first piston cylinders 301 arranged at one end of the inner side of each inner support plate 101, and one end of each first piston cylinder 301 is slidably inserted with a push-pull rod 302 fixed to the movable support plate 103, and one end of each push-pull rod 302 is fixed with a first piston plate 303 slidably connected to the inner side of the first piston cylinder 301, and also includes a hydraulic oil extrusion mechanism that drives the multiple push-pull rods 302 to move.

[0036] Furthermore, the hydraulic oil squeezing mechanism includes a second piston cylinder 304 provided inside the support tube 1, and a second piston plate 306 (such as Figure 2 As shown), an electric telescopic rod 305 is installed at the outer end of the second piston cylinder 304 to drive the second piston plate 306 to move, and the second piston cylinder 304 is connected to the inner end of the plurality of first piston cylinders 301 through a plurality of connecting oil pipes 307;

[0037] The hydraulic oil extrusion mechanism is used to evenly press the hydraulic oil into the inner side of multiple first piston cylinders 301 of the propulsion mechanism, thereby pushing the push-pull rod 302 and the first piston plate 303 to move. When the push-pull rod 302 moves, it can drive the movable support plate 103 to move. The movable support plate 103 can drive the pipeline to be installed fixed on its outside to move toward the installed pipeline, making it convenient to connect the two sections of pipeline.

[0038] Furthermore, two guide grooves 111 are provided on one side of each inner support plate 101 at the position of the movable support plate 103 (such as Figure 4 As shown), two guide slides 112 are fixed on one side of each movable support plate 103, and each guide slide 112 is slidably connected to the guide groove 111 at the corresponding position;

[0039] Through the sliding cooperation between the guide groove 111 and the guide slide 112, the movable support plate 103 can move in a straight line along the outer side of the inner support plate 101, thereby driving the outer pipe to be installed to move in a straight line, thereby improving the accuracy of pipe docking.

[0040] Furthermore, the adsorption mechanism includes a piston chamber 201 located in the middle of the movable support plate 103, and two negative pressure chambers 202 located at both ends of the movable support plate 103. The two negative pressure chambers 202 are both connected to the piston chamber 201. A connecting plate 203 is fixed at the middle of the piston chamber 201. Electromagnets 204 are installed on both sides of the connecting plate 203. Two pistons 205 are symmetrically slidably connected to the inner ends of the piston chamber 201. A plurality of first air holes 206 communicating with the outside are provided on one side of the two piston chambers 201. The two trigger mechanisms are also provided at both ends of the movable support plate 103 for controlling the circuits of the two electromagnets 204. The trigger mechanism includes a accommodating chamber 209 (such as Figure 7 As shown in FIG, a pressure rod 211 is slidably inserted into the upper end of the accommodating chamber 209, a pressure plate 214 is fixed to one end of the pressure rod 211, and a slide plate 210 slidably connected to the inner side of the accommodating chamber 209 is fixed to the other end of the pressure rod 211. A trigger switch 212 electrically connected to the electromagnet 204 is installed at the inner bottom end of the accommodating chamber 209, and one end of the slide plate 210 is elastically connected to the inner bottom end of the accommodating chamber 209 via a return spring 213;

[0041] Through the adsorption mechanism, negative pressure is formed between the rubber pad 208 and the inner side of the pipe to be installed, which can increase the pressure between the rubber pad 208 and the inner side of the pipe to be installed, thereby increasing the friction between the two. When the multiple movable support plates 103 pull the pipe to be installed to move, slipping between the movable support plates 103 and the pipe to be installed can be effectively avoided, ensuring the stability of the docking of the two sections of pipe, thereby further improving the efficiency of pipe laying.

[0042] Furthermore, one end of each of the two negative pressure chambers 202 is connected to a tension spring 207 , and one end of each of the two tension springs 207 is connected to one end of each of the two pistons 205 ;

[0043] When a section of pipe is laid, it is necessary to control the multiple movable support plates 103 to separate from the inner side of the pipe to be installed. After separation, the electromagnet 204 in the adsorption mechanism is powered off and loses the electromagnetic attraction to the piston 205. At this time, the piston 205 can move in the opposite direction under the elastic force of the tension spring 207, so that the air pressure inside the negative pressure chamber 202 is quickly balanced with the outside world, making it easier for the rubber pad 208 to quickly separate from the inner side of the pipe to be installed.

[0044] Furthermore, the support mechanism includes two vertical plates 9 fixed to the upper side of the driving chassis 2, two upper connecting rods 5 and two lower connecting rods 6 are rotatably connected between the two vertical plates 9, the ends of the two upper connecting rods 5 and the two lower connecting rods 6 are rotatably connected to a vertical plate 8, one end of the support tube 1 is fixed to the lower end of the vertical plate 8 by a bolt, and a hydraulic cylinder 7 for driving the upper connecting rod 5 and the lower connecting rod 6 to rotate is also rotatably installed between the two vertical plates 9, and the two upper connecting rods 5 and the two lower connecting rods 6 are parallel to each other and have equal lengths;

[0045] The supporting mechanism can keep the supporting pipe 1 at a horizontal angle while moving up and down, so that the pipeline to be installed outside the supporting pipe 1 can be moved to the inside of the groove at a horizontal angle, so that the pipeline to be installed and the pipeline installed in the groove can be kept in line, which facilitates the docking of the two sections of pipeline, reduces the difficulty of docking, and improves the efficiency of pipeline laying.

[0046] Working principle: When in use, the two driving motors 3 on the driving vehicle body are controlled to run and respectively drive the two driving wheels 4 to rotate, thereby driving the driving chassis 2 to move on the ground. When the two driving motors 3 rotate at different speeds, the two driving wheels 4 can be driven to rotate at different speeds, which can realize the turning of the driving vehicle body. The support tube 1 can be driven to move by controlling the movement of the driving vehicle body, so that the support tube 1 is inserted into the pipe to be installed, and the pipe to be installed can be sleeved on the outside of the support tube 1, and then the driving vehicle body and the support tube 1 can be used to drive the pipe to be installed to the inside of the pre-dug trench. The telescopic end of the hydraulic cylinder 7 in the supporting mechanism is controlled to extend and retract, which can drive the two lower connecting rods 6 to rotate around the connection point with the vertical plate 9. Since the two upper connecting rods 5 and the two lower connecting rods 6 are parallel to each other and have equal lengths, The upper connecting rod 5, the lower connecting rod 6, the vertical plate 8 and the vertical plate 9 form a parallelogram connecting rod mechanism. When the two lower connecting rods 6 rotate, the two upper connecting rods 5 can be driven to rotate synchronously, thereby driving the vertical plate 8 to maintain a vertical angle and move up and down in an arc, so that the support pipe 1 and the outer pipe to be installed can be moved down into the groove, so that the pipe to be installed is aligned with the end of the pipe installed in the groove, which improves the convenience of operation. Since the vertical plate 8 always maintains a vertical angle, the support pipe 1 can always maintain a horizontal angle. After the pipe to be installed is fixed on the outside of the support pipe 1, the pipe to be installed can be moved to the inside of the groove at a horizontal angle, so that the pipe to be installed and the pipe installed in the groove can be kept in the same line, which facilitates the docking of the two sections of pipes, reduces the difficulty of docking, and improves the efficiency of pipe laying.

[0047] In order to improve the alignment accuracy and efficiency between the pipe to be installed and the installed pipe, the pipe to be installed is located on the outside of the support pipe 1 close to the movable support plate 103, and the installed pipe is located in the groove. The support pipe 1 is extended into the installed pipe in the groove so that the installed pipe is close to the fixed support plate 102. Figure 8 As shown, the motor 110 in the telescopic mechanism is controlled to operate and drive the screw 106 to rotate. The screw 106 drives the internal threaded sleeve 107 on its outer side to move axially through the thread. The internal threaded sleeve 107 drives the multiple sliding pins 108 to move axially through the multiple sliding pin brackets 109, so that the sliding pins 108 slide along the inner side of the inclined slide groove 105. Through the sliding cooperation between the multiple sliding pins 108 and the multiple inclined slide grooves 105, the multiple inner support plates 101 can be driven to extend synchronously to the outside of the support tube 1 through the slide plate 104, and the multiple inner support plates 101 respectively drive multiple fixed The support plate 102 and the multiple movable support plates 103 extend outward, and the multiple fixed support plates 102 can support the inner side of the installed pipe, and the multiple movable support plates 103 can support the inner side of the pipe to be installed, so that the installed pipe and the pipe to be installed can be kept coaxial with the support pipe 1 at the same time, so that the end of the pipe to be installed can be aligned with the end of the installed pipe, ensuring that the axis lines of the two sections of pipe to be connected are on the same straight line, further improving the convenience of connecting the two sections of pipe, preventing misalignment when connecting the pipes, and improving the efficiency of pipe laying;

[0048] After alignment, the telescopic end of the electric telescopic rod 305 in the hydraulic oil squeezing mechanism is controlled to extend to drive the second piston plate 306 to slide on the inner side of the second piston cylinder 304. Since the inner side of the second piston cylinder 304 is filled with hydraulic oil, the hydraulic oil will flow into the inner sides of the multiple first piston cylinders 301 in the propulsion mechanism through the multiple connecting oil pipes 307 when it is squeezed by the second piston plate 306, thereby pushing the multiple first piston plates 303. After receiving the thrust, the multiple first piston plates 303 respectively push the multiple push-pull rods 302 to extend outward, and the multiple push-pull rods 302 respectively drive the multiple movable support plates 103 to move toward the fixed support plate 1 02, when the multiple movable support plates 103 move, they can drive the pipes to be installed fixed on the outside to move toward the position of the fixed support plate 102. Since the installed pipes are fixed on the outside of the multiple fixed support plates 102, the pipes to be installed can be close to the ends of the installed pipes, which is convenient for quickly connecting the two sections of pipes and facilitating the connection and fixing of the ends of the two sections of pipes. Compared with the existing method of manually connecting pipes, this method can align the two sections of pipes faster and more accurately, greatly improving the efficiency of pipe laying, and improving the accuracy of the connection between the two sections of pipes, preventing the misalignment between the two sections of pipes from affecting the sealing performance;

[0049] When the movable support plate 103 and the pipe to be installed are in contact with each other, the pressure plate 214 protruding outward in the trigger mechanism first contacts the inner side of the pipe to be installed. After the pressure plate 214 is blocked, the pressure plate 214 pushes the slide plate 210 to slide toward the inner side of the accommodating chamber 209 through the pressure rod 211. The slide plate 210 compresses the return spring 213. When the outer side of the movable support plate 103 contacts the inner side of the pipe to be installed, the pressure plate 214 can be flush with the surface of the movable support plate 103. At the same time, the slide plate 210 can just press the trigger switch 212. After the trigger switch 212 is triggered, the circuit of the electromagnet 204 in the adsorption mechanism can be turned on, so that the electromagnet 204 generates electromagnetic attraction. It should be noted that the piston 205 is made of magnetic material and can be attracted by the electromagnet 204. Therefore, the piston 205 can move to the position of the electromagnet 204 after being attracted by the electromagnetic attraction, so that it is close to the piston 205. 05, a negative pressure is formed inside a negative pressure chamber 202. Since the side of the negative pressure chamber 202 is connected to the outside through multiple first air holes 206, and a rubber pad 208 is provided on the outside of the movable support plate 103, and a second air hole connected thereto is opened at a position corresponding to each first air hole 206 on the rubber pad 208. When a negative pressure is formed inside the negative pressure chamber 202, a negative pressure can also be formed between the rubber pad 208 and the inner side surface of the pipe to be installed through the multiple first air holes 206, and the movable support plate 103 and the inner side surface of the pipe to be installed are tightly fitted together by the rubber pad 208, which can improve the sealing effect. When a negative pressure is formed between the rubber pad 208 and the inner side surface of the pipe to be installed, the pressure between the rubber pad 208 and the inner side surface of the pipe to be installed can be increased, thereby increasing the friction between the two. When the multiple movable support plates 103 pull the pipe to be installed to move, the movable support plate 103 and the pipe to be installed can be effectively avoided from slipping, thereby ensuring the stability of the docking of the two sections of pipe, thereby further improving the efficiency of pipe laying.
