Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline laying, and in particular relates to a pipeline laying device for road construction. Background Art

[0002] Pipeline laying refers to the process of transporting pipes to tunnels, installing, connecting and filling them. Pipeline laying is a time-consuming and labor-intensive project that requires connecting and laying pipes to ensure that all pipes can transport fluids. Currently, pipe laying equipment is required in road construction to lay pipes.

[0003] Existing pipe laying equipment for road construction requires the use of wire ropes to lift the pipes into the tunnel for assembly. This often results in the following problems:

[0004] 1. When using steel wire rope to lift the pipeline, the pipeline will swing greatly, making it inconvenient to adjust the fixed position of the pipeline and difficult to dock the pipeline, which increases the difficulty of the staff's work;

[0005] 2. Currently, pipeline laying is mostly done in trenches on both sides of the road. The side of the trench away from the road surface is often unable to accommodate the movement of the laying equipment. Utility Model Content

[0006] To address the aforementioned problems and shortcomings of the existing technology, the present invention provides a road construction pipe laying device. By installing a control mechanism between the clamping mechanism and the crane, the clamping mechanism's relative swing amplitude is adjusted, thereby facilitating the docking and installation of the pipe. A lifting beam protrudes from the side of the traveling frame closest to the pit to facilitate the lifting of the pipe into the pit. Furthermore, the pipe laying device does not require access to the ground on either side of the pit; it can simply travel along the side of the pit closest to the road surface to achieve the pipe lifting operation.

[0007] The utility model is realized through the following technical solutions:

[0008] A road construction pipeline laying device includes a traveling frame, a crane, a clamping mechanism, and a regulating mechanism. Two hanging beams are mounted above the traveling frame, and the hanging beams protrude from the side of the traveling frame close to the tunnel. The crane is mounted on the traveling frame and can move along the extension direction of the traveling frame. A vertical telescopic rod is mounted below the crane. The clamping mechanism is mounted below the telescopic rod. The clamping mechanism includes two relatively arranged clamping blocks and a driving mechanism that drives the two clamping blocks to move relative to each other. The inner sides of the two clamping blocks are formed with an arc-shaped surface that cooperates with the pipeline to achieve stable clamping of the pipeline. The regulating mechanism is mounted between the telescopic rod and the clamping mechanism. The regulating mechanism includes an adjusting block and a limiting block fixed to the bottom of the telescopic rod, and a conical seat fixed to the top of the driving mechanism. A conical groove that cooperates with the conical seat is provided in the limiting block. A cable roller connected to the conical seat is provided in the adjusting block to adjust the shaking amplitude of the clamping mechanism relative to the crane, so as to facilitate stable assembly of the pipeline.

[0009] Furthermore, an adjustment handle connected to the cable roller is provided on the outside of the adjustment block to facilitate the rotation of the cable roller, thereby adjusting the position of the conical seat relative to the limit block. A ratchet mechanism is provided between the adjustment handle and the cable roller to prevent the adjustment handle from loosening and causing the conical seat to separate from the limit block.

[0010] Furthermore, protective ropes are installed at the bottom of the two clamping blocks to improve the safety of the clamping blocks when clamping the pipe.

[0011] Furthermore, the driving mechanism is an electric push rod, which is connected to the clamping block, and each clamping block is installed with at least two electric push rods to adjust the clamping state of the clamping block.

[0012] Furthermore, a rubber pad is attached to the inner side of the curved surface of the clamping block to protect the pipeline.

[0013] Furthermore, a moving wheel, a fixed plate, a support plate and a second push rod that drives the support plate to move in the vertical direction are installed at the bottom of the traveling frame. The second push rod is fixed to the fixed plate, and the support plate is located below the fixed plate and is installed to the bottom of the second push rod. The traveling frame has a traveling state and a hoisting state. When the traveling frame is in the traveling state, the moving wheels of the traveling frame are in contact with the ground; when the traveling frame is in the hoisting state, the support plate of the traveling frame is in contact with the ground to ensure the stability of the hoisting state.

[0014] The pipe-laying device further includes two counterweight mechanisms, both located on the side of the carriage away from the tunnel, to prevent the pipe-laying device from tipping over. The counterweight mechanisms include a slider sleeved onto the carriage, a counterweight box secured to the slider, and a support block secured to the bottom of the slider, which abuts the top surface of the fixed plate.

[0015] Furthermore, a spring is installed between the slider and the fixed plate, and the spring has an elastic thrust to push the slider to move vertically upward, so that the counterweight box in an empty state can be lifted off the ground.

[0016] Furthermore, a drain valve is provided at the bottom of the counterweight box to release the liquid in the counterweight box.

[0017] Furthermore, a sunshade is provided on the top of the carriage to improve the comfort of the working environment.

[0018] Beneficial effects of the utility model:

[0019] 1. By installing a regulating mechanism between the clamping mechanism and the crane, the swing amplitude of the clamping mechanism relative to the crane can be adjusted to facilitate the docking installation of the pipeline;

[0020] 2. The lifting beam protrudes from the side of the traveling frame close to the tunnel to realize the lifting of the pipeline into the tunnel. The pipeline laying device does not need to occupy the ground on both sides of the tunnel. It only needs to move along the side of the tunnel close to the road surface to realize the lifting operation of the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] It should be noted that the directional terms such as left, right, up, down, front and back in the embodiments of the present invention are merely relative concepts or are based on the normal use state of the product, that is, the direction of movement of the product, and should not be considered as limiting.

[0030] In addition, it should be noted that the dynamic terms such as "relative motion" mentioned in the embodiments of the present invention not only refer to changes in position, but also include movements such as rotation and rolling in which there is no relative change in position but the state is changed.

[0031] Finally, it should be noted that when a component is referred to as being "located on" or "disposed on" another component, it can be on the other component or there may be an intervening component. When a component is referred to as being "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0032] like Figures 1 to 5A road construction pipeline laying device is shown, comprising a traveling frame 1, a crane 2, a clamping mechanism 3, and a regulating mechanism 4. Two hanging beams 11 are mounted above the traveling frame 1, and the hanging beams 11 protrude from the side of the traveling frame 1 close to the tunnel. The crane 2 is mounted to the traveling frame 1 and is movable along the extension direction of the traveling frame 1. A vertically arranged telescopic rod 21 is mounted below the crane 2. The clamping mechanism 3 is mounted below the telescopic rod 21. The clamping mechanism 3 comprises two oppositely arranged clamping blocks 31 and a driving mechanism 32 for driving the two clamping blocks 31 to move relative to each other. The inner sides of the two clamping blocks 31 are formed with arc-shaped surfaces 311 that cooperate with the pipeline to achieve stable clamping of the pipeline. The regulating mechanism 4 is installed between the telescopic rod 21 and the clamping mechanism 3. The regulating mechanism 4 includes an regulating block 41 and a limit block 42 fixed to the bottom of the telescopic rod 21, and a conical seat 43 fixed to the top of the driving mechanism 32. A conical groove 421 cooperating with the conical seat 43 is provided in the limit block 42, and a cable roller 411 connected to the conical seat 43 is provided in the regulating block 41 to regulate the shaking amplitude of the clamping mechanism 3 relative to the crane 2, so as to facilitate stable assembly of the pipeline.

[0033] In one embodiment, first, the traveling frame 1 moves along the road surface to the position where the pipeline is to be laid. Then, the crane 2 moves along the hanging beam 11 to the position directly above the pipeline, and the crane 2 drives the telescopic rod 21 to extend so that the clamping mechanism 3 reaches the pipeline clamping position. The driving mechanism 32 drives the two clamping blocks 31 to approach each other to achieve a firm clamping of the pipeline. The two cranes 2 synchronously control the two telescopic rods 21 to retract to drive the pipeline clamped by the clamping mechanism 3 to move upward. The crane 2 moves along the hanging beam 11 toward the tunnel to move the pipeline directly above the tunnel. The crane 2 drives the telescopic rod 21 to extend so that the pipeline reaches the set assembly height.

[0034] It is difficult to precisely dock the pipe to the previously laid pipe, and the pipe is clamped by the clamping mechanism 3 and is in a completely fixed state. The cable roller 411 is manually released through the adjustment block 41 of the control mechanism 4, thereby releasing the conical seat 43 and the clamping mechanism 3. The conical seat 43 is connected to the wire harness of the cable roller 411 and plugged into the conical groove 421 of the limit block 42. When the cable roller 411 releases the wire harness, the conical seat 43 moves downward relative to the limit block 42, and the conical seat 43 gradually separates from the conical groove 421. The clamping mechanism 3 fixed to the conical seat 43 can swing to a certain extent relative to the limit block 42. The longer the distance that the cable roller 411 releases the wire harness, the farther the conical seat 43 and the clamping mechanism 3 are from the limit block 42, and the greater the swing amplitude of the conical seat 43 and the clamping mechanism 3 relative to the entire crane 2. The swing amplitude of the clamping mechanism 3 relative to the crane 2 is adjusted by the regulating mechanism 4, thereby facilitating the docking installation of the pipeline.

[0035] It should be noted that during the pipeline laying process, it is difficult to dock a completely fixed pipeline with a previously laid pipeline. Pipes hoisted with a crane and ropes experience significant swaying, making docking and installation inconvenient. The control mechanism 4 of the pipeline laying device improves pipeline installation and docking efficiency by regulating the swaying amplitude of the pipeline during installation.

[0036] Preferably, an adjustment handle 412 connected to the cable roller 411 is provided on the outside of the adjustment block 41 to facilitate the rotation of the cable roller 411, thereby adjusting the position of the conical seat 43 relative to the limit block 42. A ratchet mechanism 413 is provided between the adjustment handle 412 and the cable roller 411 to prevent the adjustment handle 412 from loosening and causing the conical seat 43 to separate from the limit block 42.

[0037] In one embodiment, the cable harness on the cable roller 411 is released manually by rotating the adjustment handle 412. A ratchet mechanism 413 is provided between the adjustment handle 412 and the cable roller 411. When the adjustment handle 412 is manually released, the ratchet mechanism 413 can be locked to lock the cable roller 411. To tighten the harness on the cable roller 411, the adjustment handle 412 can be rotated in the opposite direction. Since the ratchet is in the open position, even if the adjustment handle 412 is accidentally released, the clamping mechanism 3 and the pipe will not fall.

[0038] Preferably, a protective rope 312 is installed at the bottom of the two clamping blocks 31 to improve the safety of the clamping blocks 31 when clamping the pipe.

[0039] In one embodiment, when hoisting a pipeline, the protective rope 312 can be passed under the two clamping blocks 31 so that the two clamping blocks 31 and the protective rope 312 together surround the pipeline to prevent the pipeline from escaping from the clamping blocks 31, thereby improving the safety of hoisting the pipeline.

[0040] Preferably, the driving mechanism 32 is an electric push rod 321 , which is connected to the clamping block 31 , and at least two electric push rods 321 are installed on each clamping block 31 to adjust the clamping state of the clamping block 31 .

[0041] In one embodiment, two electric push rods 321 are provided on both sides of each driving mechanism 32 to provide power support for the opening and closing operation of the clamping block 31 .

[0042] Preferably, a rubber pad is attached to the inner side of the arcuate surface 311 of the clamping block 31 to protect the pipeline.

[0043] Preferably, a moving wheel 12, a fixed plate 13, a support plate 14 and a second push rod 15 for driving the support plate 14 to move in the vertical direction are installed at the bottom of the traveling frame 1. The second push rod 15 is fixed to the fixed plate 13, and the support plate 14 is located below the fixed plate 13 and is installed to the bottom of the second push rod 15. The traveling frame 1 has a traveling state and a hoisting state. When the traveling frame 1 is in the traveling state, the moving wheel 12 of the traveling frame 1 is in contact with the ground; when the traveling frame 1 is in the hoisting state, the support plate 14 of the traveling frame 1 is in contact with the ground to ensure the stability of the hoisting state.

[0044] In one embodiment, when the traveling frame 1 moves to the hoisting position, the second push rod 15 pushes the support plate 14 downward so that the support plate 14 abuts against the ground, thereby improving the stability when hoisting the pipe.

[0045] Preferably, the pipe-laying device also includes a counterweight mechanism 5. Two counterweight mechanisms 5 are provided, each located on the side of the carriage 1 away from the tunnel to prevent the pipe-laying device from tipping over. The counterweight mechanism 5 includes a slider 51 sleeved onto the carriage 1, a counterweight box 52 secured to the slider 51, and a support block 53 secured to the bottom of the slider 51. The support block 53 abuts the top surface of the fixed plate 13.

[0046] Preferably, a spring 54 is installed between the slider 51 and the fixed plate 13. The spring 54 has an elastic thrust to push the slider 51 to move vertically upward, so that the counterweight box 52 in an unloaded state can be lifted off the ground.

[0047] In one embodiment, before the lifting operation, counterweights are added to the counterweight box 52 to prevent the pipe laying apparatus from tipping over during the pipe lifting operation. When the counterweights are added, the box 52 and the slider 51 move downward, compressing the spring 54 until the support block 53 below the slider 51 abuts the fixed plate 13. When the counterweights are removed, the box 52 and the slider 51 move vertically upward, lifted off the ground, under the action of the spring 54, thereby facilitating the movement of the counterweight mechanism 5 by the traveling frame 1.

[0048] Preferably, a drain valve 521 is provided at the bottom of the counterweight box 52 to release the liquid in the counterweight box 52 .

[0049] In one embodiment, liquid such as water can serve as the counterweight of the counterweight box 52 , and a drain valve 521 is provided at the bottom of the counterweight box 52 to facilitate the release of the counterweight liquid.

[0050] Preferably, a sunshade 6 is provided on the top of the traveling frame 1 to improve the comfort of the working environment.

[0051] When using the aforementioned road construction pipe laying device, a control mechanism 4 is installed between the clamping mechanism 3 and the crane 2 to adjust the swing amplitude of the clamping mechanism 3 relative to the crane 2, thereby facilitating the docking and installation of the pipe. A lifting beam 11 protrudes from the side of the traveling frame 1 near the tunnel to facilitate the lifting of the pipe into the tunnel. The pipe laying device does not require the use of ground on both sides of the tunnel; it can simply move along the side of the tunnel near the road surface to complete the pipe lifting operation.

[0052] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
