Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, and in particular to a trenching and positioning device for pipeline laying. Background Technology

[0002] Trenching devices used for pipeline laying are engineering equipment specifically designed for excavating trenches, also known as trenching machines. They cut the soil through chain drive or rotating milling discs to form regular trenches, and are suitable for laying underground facilities such as cables and pipelines.

[0003] In pipeline laying projects, the accuracy of trench positioning directly affects the efficiency of subsequent pipeline connection and project quality. Current technology often uses temporary marker poles (markers) inserted into the ground as positioning benchmarks, combined with rangefinders and other equipment to form a multi-source positioning mechanism. These marker poles are typically fixed to the ground using a simple plug-in method. However, this technical solution has certain drawbacks in actual construction: because the marker poles are only temporarily fixed, they are easily displaced in complex construction environments due to factors such as collisions with construction machinery, wind, or natural soil settlement, leading to deviations in the established positioning benchmark. This displacement phenomenon is particularly prominent in municipal engineering or long-distance pipeline laying. A single displacement can trigger a chain reaction of errors, ultimately causing excessive axial deviation during pipeline connection, forcing the construction team to repeat measurements and calibrations, significantly increasing labor costs and the risk of project delays.

[0004] Therefore, there is an urgent need to provide a trenching and positioning device for pipeline laying to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a trenching positioning device for pipeline laying.

[0006] To solve the above-mentioned technical problems, the present invention provides a trenching positioning device for pipeline laying, including a marking rod, wherein a sleeve is slidably connected to the outside of the marking rod;

[0007] The bottom of the sleeve is connected to an elastic mechanism, and the bottom of the elastic mechanism is connected to multiple arc-shaped plates;

[0008] The elastic mechanism is used to keep the arc-shaped plate in contact with the marking rod. Each of the arc-shaped plates has a long plate slidably connected to its bottom, and the bottom end of the long plate is connected to a rotating mechanism.

[0009] The rotating mechanism is internally connected to multiple fixed rods. The rotating mechanism and the fixed rods cooperate to assist in positioning the marker rod. The interior of the multiple arc-shaped plates is hollow, and the bottom of the marker rod and the fixed rod are both pointed.

[0010] The present invention is further configured such that: the elastic mechanism includes a plurality of first brackets fixedly connected to the bottom of the sleeve, each of the plurality of first brackets having a rotating shaft rotatably connected inside, the exterior of the plurality of rotating shafts being fixedly connected to the top of a plurality of arc-shaped plates respectively, and corresponding one to one; each of the plurality of rotating shafts having a torsion spring sleeved on the exterior, the two ends of the torsion spring being fixedly connected to the exterior of the rotating shaft and the first bracket respectively.

[0011] Through the above technical solution, the function of the elastic mechanism is to make the arc-shaped plate fit against the marking rod; when not in use, the torsion spring keeps the arc-shaped plate in contact with the marking rod, reducing the space occupied by the arc-shaped plate; when the marking rod is needed, it is inserted into the ground, the sleeve slides downward, driving the first bracket and the rotating shaft to move downward, twisting the torsion spring, causing the arc-shaped plate and the long plate to deflect downward, and one end of the long plate to move outward, and then the arc-shaped plate and the long plate diagonally support the marking rod, thus providing auxiliary support for the marking rod; when it needs to be retracted, the torsion spring drives the arc-shaped plate to automatically reset, which is convenient, quick, simple and practical.

[0012] The present invention is further configured such that: each of the plurality of arc-shaped plates is connected to two springs, the two ends of the springs are respectively fixedly connected to the inside of the arc-shaped plate and one end of the long plate, and the plurality of arc-shaped plates are arranged in a circular array with the marker rod as the center.

[0013] With the above technical solution, when the machine accidentally collides with the marker pole, the spring will buffer the impact, and when the machine moves away, the spring will automatically reset, reducing the possibility of the marker pole deviating after being collided with.

[0014] The present invention is further configured such that: the rotating mechanism includes multiple inclined plates that are fixedly connected to the bottom of multiple long plates, and correspond one to one; each of the multiple inclined plates has a groove; each of the multiple grooves has two fixed shafts fixedly connected to it; a collar is rotatably connected between each pair of fixed shafts; and multiple fixed rods are slidably connected to multiple collars, and correspond one to one.

[0015] Through the above technical solution, the function of the rotating mechanism is to assist in positioning the marker rod; the marker rod is inserted into the ground, the sleeve slides downward, causing the arc plate and the long plate to deflect downward, causing one end of the long plate to move outward until it moves to the required position, and then the fixing rod is flipped so that the tip of the fixing rod faces the ground, and the fixing rod is stepped on downward so that the fixing rod can be inserted into the ground, thereby assisting in positioning the marker rod.

[0016] The present invention is further configured such that: a stop block is fixedly connected to the outside of the marking rod, and the top of the sleeve is in contact with the stop block.

[0017] Through the above technical solution, the function of the stop block is to block the sleeve and limit its movement.

[0018] The present invention is further configured such that: two mirror-symmetrical bolts are rotatably connected inside the sleeve by a thread, and one end of each of the two bolts abuts against the marking rod.

[0019] Through the above technical solution, the function of the bolt is to fix the sleeve. When the marking rod is needed, the sleeve is slid down and then the bolt is rotated to limit the sleeve. When it is not needed, the sleeve is slid to abut against the stop block and then the bolt is rotated.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model achieves space optimization in the non-use state through an elastic mechanism, and uses a torsion spring to drive the arc plate to naturally fit the marking rod, reducing the volume occupied by the structure; the marking rod is supported by the linkage of the arc plate and the long plate diagonal bracing, and when the sleeve slides, it drives the long plate to deflect outward to form a triangular support structure, which enhances the vertical stability of the marking rod.

[0022] 2. This utility model absorbs collision energy through spring buffering. When construction machinery collides with the marking pole, the spring attenuates the impact force through deformation, preventing the marking pole from shifting due to external force. The combination of the rotating mechanism and the fixed rod achieves dual positioning. After the inclined plate drives the fixed axis to move outward, the fixed rod inserts into the ground to form an inclined brace for fixation, further preventing the marking pole from shifting due to soil settlement or wind.

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-6 This embodiment of a trenching positioning device for pipeline laying includes a marking rod 1. A sleeve 2 is slidably connected to the outside of the marking rod 1. An elastic mechanism 3 is connected to the bottom of the sleeve 2. Multiple arc-shaped plates 4 are connected to the bottom of the elastic mechanism 3. The arc-shaped plates 4 are hollow inside. The elastic mechanism 3 is used to keep the arc-shaped plates 4 in contact with the marking rod 1. The elastic mechanism 3 includes multiple first supports 301 fixedly connected to the bottom of the sleeve 2. A rotating shaft 302 is rotatably connected inside each of the multiple first supports 301. The outside of the multiple rotating shafts 302 is fixedly connected to the top of the multiple arc-shaped plates 4, and they correspond one-to-one. A torsion spring 303 is sleeved on the outside of each of the multiple rotating shafts 302. The two ends of the torsion spring 303 are respectively connected to the rotating shaft 302. The external first bracket 301 is fixedly connected. The function of the elastic mechanism 3 is to make the arc plate 4 fit against the marking rod 1. When not in use, the torsion spring 303 makes the arc plate 4 fit against the marking rod 1, reducing the space occupied by the arc plate 4. When the marking rod 1 is needed, the marking rod 1 is inserted into the ground, the sleeve 2 slides down, and the first bracket 301 and the rotating shaft 302 move downward, twisting the torsion spring 303. The arc plate 4 and the long plate 5 deflect downward, and one end of the long plate 5 moves outward. Then the arc plate 4 and the long plate 5 support the marking rod 1 at an angle, thus providing auxiliary support for the marking rod 1. When it needs to be retracted, the torsion spring 303 drives the arc plate 4 to automatically reset, which is convenient, quick, simple and practical.

[0033] like Figures 2-3 As shown, each of the multiple arc-shaped plates 4 is connected to two springs 304. The two ends of the springs 304 are fixedly connected to the inside of the arc-shaped plate 4 and one end of the long plate 5, respectively. The multiple arc-shaped plates 4 are arranged in a circular array with the marker rod 1 as the center. When the machine accidentally collides with the marker rod 1, it is buffered by the springs 304. After the machine moves away, it is automatically reset by the springs 304, reducing the possibility of deviation after the marker rod 1 is collided.

[0034] like Figures 4-6As shown, multiple curved plates 4 are slidably connected to long plates 5 at their bottom. A rotating mechanism 6 is connected to the bottom of each long plate 5. Multiple fixed rods 7 are connected within the rotating mechanism 6. The rotating mechanism 6 and the fixed rods 7 cooperate to assist in positioning a marker rod 1. Both the marker rod 1 and the fixed rod 7 have pointed bottoms. The rotating mechanism 6 includes multiple inclined plates 601 fixedly connected to the bottom of the multiple long plates 5, in a one-to-one correspondence. Each of the multiple inclined plates 601 has a groove 602, and each of the multiple grooves 602 has two fixed shafts 603 fixedly connected to it. Each pair of fixed shafts 603... Each of the three components is rotatably connected by a collar 604. Multiple fixed rods 7 are slidably connected to multiple collars 604, and they correspond one-to-one. The function of the rotating mechanism 6 is to assist in positioning the marker rod 1. The marker rod 1 is inserted into the ground, and the sleeve 2 is slid downward, causing the arc plate 4 and the long plate 5 to deflect downward, causing one end of the long plate 5 to move outward until it reaches the required position. Then, the fixed rod 7 is flipped so that the tip of the fixed rod 7 faces the ground. The fixed rod 7 is stepped on downward so that it can be inserted into the ground, thereby assisting in positioning the marker rod 1.

[0035] like Figures 4-6 As shown, a stop 605 is fixedly connected to the outside of the marking rod 1. The top of the sleeve 2 is in contact with the stop 605. The function of the stop 605 is to block the sleeve 2 and limit its movement.

[0036] like Figures 4-6 As shown, two mirror-symmetrical bolts 606 are connected inside the sleeve 2 by a threaded connection. One end of each bolt 606 abuts against the marking rod 1. The function of the bolts 606 is to fix the sleeve 2. When the marking rod 1 is needed, the sleeve 2 is slid down and then the bolts 606 are rotated to limit the position of the sleeve 2. When it is not needed, the sleeve 2 is slid down to abut against the stop block 605 and then the bolts 606 are rotated.

[0037] In use, the sleeve 2 is connected to the arc-shaped plate 4 via the first bracket 301 and the rotating shaft 302. The torsion spring 303 allows the arc-shaped plate 4 to naturally conform to the marking rod 1, reducing space occupation. During use, the marking rod 1 is inserted into the ground, and the sleeve 2 slides downwards, causing the first bracket 301 and the rotating shaft 302 to move downwards and twist the torsion spring 303, causing the arc-shaped plate 4 and the long plate 5 to deflect downwards. One end of the long plate 5 moves outwards, and the arc-shaped plate 4 and the long plate 5 diagonally support the marking rod 1 to provide auxiliary support. Simultaneously, the outward movement of the long plate 5 causes the inclined plate 601 and the fixed shaft 603 to move outwards until the long plate 1... The plate 5 is moved to the required position, the fixing rod 7 is flipped and inserted into the ground to further assist in positioning, and then the bolt 606 is rotated to complete the fixation; the long plate 5 is connected inside the arc plate 4 by the spring 304, and the spring 304 buffers the mechanical collision to reduce the deviation of the marking rod 1; when retracted, the sleeve 2 is slid upward, and the torsion spring 303 drives the arc plate 4 to automatically reset; the sleeve 2 is limited by the stop 605 and fixed in position by the bolt 606, thereby effectively solving the problem of displacement of the marking rod 1 due to collision, wind or soil settlement in the construction environment, and maintaining the stability of the positioning benchmark.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
