Description

Technical Field

[0001] The present invention relates to the technical field of buried pipes in water conservancy projects, and particularly to a construction mechanism for buried pipes in water conservancy projects. Background Technique

[0002] Buried pipes in water conservancy projects refer to technical measures of burying pipes underground or inside the dam body during the construction of water conservancy projects, which are mainly used for water conveyance, irrigation, flood discharge, etc. When conducting underground pipe burying, it is necessary to first dig a trench on the ground and use auxiliary vehicles for pipe placement.

[0003] The above-mentioned device does not have a structure in which the pipe placement vehicle moves directionally along with the trench, automatically picks up the pipe onto the vehicle, and places the pipe after the pipe and the trench are centered. When the existing auxiliary pipe placement vehicle is in use, its driving direction is extremely susceptible to the ground road. Moreover, if the buried pipe trench has a curvature or a turning point, it is necessary to manually adjust the moving direction of the auxiliary vehicle. During the pipe burying process, it is necessary to manually move the long pipe connected by hot melting beside the trench onto the vehicle for pipe placement. This is not only rather cumbersome, but also difficult to accurately position the pipe and the trench. If the pipe is directly pushed into the buried pipe trench, it is extremely easy to break or crack the hot melting connection of the pipe. Based on the existing technical deficiencies, the present invention designs a construction mechanism for buried pipes in water conservancy projects. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. For this kind of buried pipe construction mechanism for water conservancy projects, after lifting the main body of the pipe-laying vehicle and placing it above the pipeline trench, place the left and right crawler wheels on both sides of the trench on the ground and insert the deviation correction mechanism into the pipeline trench. Then start the motor to drive the rotating rod and the spiral screw head to rotate forward. The rotating spiral screw head drives the lead screw to rotate forward through the driven gear. The rotation of the lead screw drives the threaded sleeve to move upward. During the upward movement, the push arm uses the second hinge block and the first hinge block to push the deviation correction plate to expand outward under the limitation of the second adjustment groove, the support pulley and the slider until the deviation correction wheels contact the inner walls on both sides of the pipeline trench. At this time, the equipment can be started to control the crawler wheels to move forward. During the forward movement, if the main body of the pipe-laying vehicle and the crawler wheels are deflected due to the terrain, the deviation correction plate and the deviation correction wheels can always limit and correct the moving direction of the main body of the pipe-laying vehicle. If the pipeline trench changes direction due to bending, the deviation correction plate and the deviation correction wheels can also change the moving direction of the main body of the pipe-laying vehicle and the crawler wheels by using the sliding connection with the inner wall of the pipeline trench. This device is convenient for using the pipeline trench to limit the moving direction of the main body of the pipe-laying vehicle.

[0016] 2. For this kind of buried pipe construction mechanism for water conservancy projects, place the main body of the pipe-laying vehicle to be buried above the trench and use the deviation correction mechanism for positioning. Then drag one end of the pipeline onto the main body of the pipe-laying vehicle. Pull the traction ring on the same side as the pipeline outward to make the traction first lock rod be pulled out from the inside of the first lock hole to release the limit on the rotating seat and the pipe-taking arc plate. Then rotate the rotating seat, the bracket and the pipe-taking arc plate to make them have the same bending angle as the pipeline, and then loosen the traction ring. Use the resilience of the first spring to insert the first lock rod back into the corresponding first lock hole to lock the rotating seat and the pipe-taking arc plate. This device is convenient for moving the pipeline placed beside the trench onto the main body of the pipe-laying vehicle for center alignment processing.

[0017] 3. For this kind of buried pipe construction mechanism for water conservancy projects, place the pipeline on the pipe-taking arc plate and control the crawler wheels and the main body of the pipe-laying vehicle to move a certain distance. The moving main body of the pipe-laying vehicle uses the pipe-taking arc plate to slowly move the pipelines on both sides of the trench above the main body of the pipe-laying vehicle, so that one end of the pipeline passes through between the two positioning rollers. Then lift the top plate to drive the second lock rod to be pulled out from the second lock hole. Then push the adjusting blocks, the support arms and the top blocks on both sides to drive the positioning rollers to move inward, so that the two positioning rollers are clamped on both sides of the pipeline for limitation, and then loosen the top plate to make the second lock rod be inserted back into the second lock hole to limit the positioning rollers. Finally, start the crawler wheels to drive the main body of the pipe-laying vehicle to continuously move under the limitation of the deviation correction mechanism. Use the pipe-taking mechanism and the positioning mechanism to continuously move the pipeline above the main body of the pipe-laying vehicle for centering alignment processing. The pipeline passing through between the two positioning rollers falls on the pipe-laying pulley and the pipe-laying roller in the pipe-laying groove, and is slowly placed into the pipeline trench by the pipe-laying roller. This device is convenient for aligning the pipeline with the trench and putting it in. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Working principle: When a buried pipe construction mechanism for water conservancy projects is in use, in the initial state, first, the crawler wheels 102 are arranged at the bottom of the buried pipe vehicle main body 1. A pipe-releasing pulley 201 is installed on the slope of the pipe-releasing groove 2 opened at the tail end of the buried pipe vehicle main body 1. Pipe-releasing rollers 204 are installed on the side blocks 202 and the pipe-releasing frame 203 fixedly connected to the inner side of the pipe-releasing groove 2 to facilitate sending the pipeline into the pipeline trench. A pipe-taking arc plate 311 is installed on the fixed seat 301 at the front end of the buried pipe vehicle main body 1 through a rotating seat 308 and a bracket 310. An adjusting block 403, a support arm 404, and a top block 405 are slidably connected in the first adjusting groove 401 opened between the pipe-taking mechanism 3 and the pipe-releasing groove 2. A positioning roller 409 is rotatably connected between the adjusting block 403 and the top block 405 to facilitate moving the pipeline placed on one side of the pipeline trench to above the buried pipe vehicle main body 1 and the trench for centering alignment. A slider 503, a support pulley 504, and a deviation-correcting plate 505 are slidably connected on the limit track 501 arranged at the bottom of the buried pipe vehicle main body 1. A lead screw 513, a threaded sleeve 515, a second hinge block 516, a push arm 517, and a first hinge block 506 arranged between the two deviation-correcting plates 505 are controlled by the lead screw 513 through a rotating rod 508, a spiral thread 509, and a motor 510 to facilitate making the deviation-correcting plates 505, the fixed frame 518, and the deviation-correcting wheels 519 fit the inner walls of trenches with different widths, thereby limiting the moving direction of the buried pipe vehicle main body 1; When it is necessary to limit the moving direction of the buried pipe vehicle main body 1 by using the pipeline trench, first lift the buried pipe vehicle main body 1 and place it above the pipeline trench, then place the left and right crawler wheels 102 on the ground on both sides of the trench and insert the deviation-correcting mechanism 5 into the pipeline trench. Then start the motor 510 to drive the rotating rod 508 and the spiral thread 509 to rotate forward. The rotating spiral thread 509 drives the lead screw 513 to rotate forward through the driven gear 514. Use the rotation of the lead screw 513 to drive the threaded sleeve 515 to move upward. During the upward movement, the push arm 517 uses the second hinge block 516 and the first hinge block 506 to push the deviation-correcting plates 505 to expand outward under the limitation of the second adjusting groove 502, the support pulley 504, and the slider 503 until the deviation-correcting wheels 519 contact the inner walls on both sides of the pipeline trench. At this time, the equipment can be started to control the crawler wheels 102 to move forward. During the forward movement, if the buried pipe vehicle main body 1 and the crawler wheels 102 deviate due to the terrain, the deviation-correcting plates 505 and the deviation-correcting wheels 519 can always limit and correct the moving direction of the buried pipe vehicle main body 1. If the pipeline trench changes direction due to bending, the deviation-correcting plates 505 and the deviation-correcting wheels 519 can also change the moving direction of the buried pipe vehicle main body 1 and the crawler wheels 102 by using the sliding connection with the inner wall of the pipeline trench. This device facilitates limiting the moving direction of the buried pipe vehicle main body 1 by using the pipeline trench.

[0030] When it is necessary to align and place the pipeline with the trench, first place the main body 1 of the pipe-laying vehicle above the trench and use the deviation rectifying mechanism 5 for positioning. Then drag one end of the pipeline onto the main body 1 of the pipe-laying vehicle, pull the traction ring 307 on the same side as the pipeline outwards to extract the first locking rod 303 from the inside of the first locking hole 309 to release the limit on the rotating seat 308 and the pipe-taking arc plate 311, and rotate the rotating seat 308, the bracket 310 and the pipe-taking arc plate 311 to make them have the same bending angle as the pipeline, and then release the traction ring 307. Use the resilience of the first spring 305 to insert the first locking rod 303 back into the corresponding first locking hole 309 to lock the rotating seat 308 and the pipe-taking arc plate 311. At this time, place the pipeline on the pipe-taking arc plate 311, control the crawler wheels 102 and the main body 1 of the pipe-laying vehicle to move a certain distance. The moving main body 1 of the pipe-laying vehicle uses the pipe-taking arc plate 311 to slowly move the pipelines on both sides of the trench above the main body 1 of the pipe-laying vehicle, so that one end of the pipeline passes through between the two positioning rollers 409. Then lift the top plate 414 upwards to drive the second locking rod 415 to be extracted from the second locking hole 402, and then push the adjusting blocks 403, the support arms 404 and the top blocks 405 on both sides to drive the positioning rollers 409 to move inwards, so that the two positioning rollers 409 clamp and limit the pipeline on both sides, and release the top plate 414 to insert the second locking rod 415 back into the second locking hole 402 to limit the positioning rollers 409. Finally, start the crawler wheels 102 to drive the main body 1 of the pipe-laying vehicle to continuously move under the limit of the deviation rectifying mechanism 5, and use the pipe-taking mechanism 3 and the positioning mechanism 4 to continuously move the pipeline above the main body 1 of the pipe-laying vehicle for centering and alignment processing. The pipeline passing through between the two positioning rollers 409 falls on the pipe-laying pulley 201 and the pipe-laying roller 204 in the pipe-laying groove 2, and is slowly placed in the pipeline trench by the pipe-laying roller 204. This device is convenient for aligning and placing the pipeline with the trench.
