Description

Technical Field

[0001] The invention relates to the field of pipeline laying, in particular to a pressure pipeline laying device for gas engineering construction. Background Art

[0002] Gas is a gas fuel that is supplied from a gas source point to towns or residential areas through the gas transmission and distribution and supply system in towns or residential areas for production, life and other purposes, and meets the gas quality requirements of the regulations. In order to ensure the normal supply and transportation of gas, it is often necessary to lay a large number of pressure pipelines with the help of pipeline laying equipment to prevent leakage during gas transmission.

[0003] After searching, the Chinese patent announcement number CN113772575B discloses a pressure pipeline laying device for urban gas engineering. The patent includes a mounting frame and a hydraulic lifting mechanism. A movable groove is opened on the outer wall of the bottom of the connecting plate. Two groups of movable blocks are slidably installed in the inner cavity of the movable groove. The outer walls of the two groups of movable plates close to each other are both installed with a fixed component. The fixed component includes a movable plate movably connected to the outer wall of the movable plate. The outer walls of the two groups of movable plates close to each other are both installed with a clamping plate. The device rotates in the inner cavity of the mounting hole through the rotating rod of the fixed component, and the guide block slides in the inner cavity of the guide groove. The moving and rotating blocks rotate in the inner cavity of the opening, which plays a compensating role for the fixed pipeline, so that the laying equipment will not squeeze the pipeline when moving in the uneven area, and the pipeline is protected. However, before laying the existing gas pressure pipeline, it is necessary to dig a tunnel that can accommodate the pipeline diameter plus the width of the clamping device to carry out the pipeline laying operation normally. Otherwise, after the installation is completed, the clamping assembly will be stuck in the tunnel during the process of being moved out, and when laying, the two sides of the pipeline are often clamped and supported, and there is a lack of support for the bottom of the pipeline, which affects the stability during installation and laying.

[0028] The present invention will be further described below in conjunction with the accompanying drawings:

[0029] like Figure 1 — Figure 7 As shown, a pressure pipeline laying device for gas engineering construction includes a lifting plate 101 and two moving seats 102, a hydraulic cylinder 103 is installed on the moving seat 102, the output end of the hydraulic cylinder 103 is connected to the bottom of the lifting plate 101 by bolts, and a mounting mechanism is arranged at the bottom of the lifting plate 101, and the mounting mechanism includes two symmetrically arranged moving rods 201, and the moving rods 201 are movably mounted at the bottom of the lifting plate 101, and a rotating mechanism is arranged on the moving rods 201, and the rotating mechanism includes a plurality of groups of symmetrically arranged rotating rods 3 01, the rotating rod 301 is rotatably connected to the moving rod 201, and the bottom of the rotating rod 301 is connected to the connecting seat 302 by bolts. The connecting seat 302 is provided with a supporting mechanism, and the supporting mechanism includes an arc rod 401, and the bottom of the arc rod 401 is connected to the supporting seat 402 by bolts. The moving rod 201 is provided with a driving component for rotating the rotating rod 301 and the supporting seat 402, and a pad 403 is bonded to the top of the supporting seat 402. The pad 403 is made of elastic material and fits the bottom of the gas pipeline when laid.

[0030] In this embodiment, the same group of arc rods 401 and the supporting seats 402 are symmetrically arranged, and the opposite sides of the same group of supporting seats 402 are respectively provided with grooves 404 and docking plates 405. The arrangement of the grooves 404 and the docking plates 405 can make the supporting seats 402 and the arc rods 401 better fit on both sides of the gas pipeline, thereby improving the stability of laying and installation.

[0031] In this embodiment, the docking plate 405 is connected to the supporting seat 402 by bolts, and the end of the supporting seat 402 away from the docking plate 405 is set to be circular. When the gas pipeline is laid, the setting of the supporting seat 402 and the docking plate 405 can make the supporting seat 402 bear the force more evenly, thereby improving the bearing stability of the gas pipeline.

[0032] In this embodiment, a reinforcing rod 406 is welded to the bottom of the supporting seat 402. The provision of the reinforcing rod 406 enables the supporting seat 402 to better withstand the gravity of the gas pipeline.

[0033] In this embodiment, the opposite side of the arc rod 401 is set to be circular, which ensures that the arc rod 401 fits against the side wall of the gas pipeline and facilitates the rotation of the arc rod 401 to move the supporting seat 402 out of the tunnel.

[0034] In this embodiment, a moving block 303 is rotatably connected to the top of the rotating rod 301 , and a plurality of sliding grooves 106 are provided at the bottom of the lifting plate 101 , and the moving block 303 is slidably connected in the sliding grooves 106 .

[0035] In this embodiment, the installation mechanism includes an electric motor 202, which is connected to the bottom of the lifting plate 101 by bolts. The output end of the motor 202 is connected to a bidirectional screw rod 203 through a coupling. The bidirectional screw rod 203 is threadedly connected to the two moving rods 201 respectively. The end of the bidirectional screw rod 203 away from the motor 202 is connected to a fixed plate 204 through a bearing. The fixed plate 204 is connected to the bottom of the lifting plate 101 by bolts.

[0036] In this embodiment, the driving assembly includes a pneumatic push rod 304, which is connected to the moving rod 201 by bolts. The output end of the pneumatic push rod 304 is connected to a push plate 305 by bolts. The push plate 305 is connected to a plurality of racks 306 by bolts. The rotating rod 301 is connected to a gear 307 meshing with the rack 306 by bolts. The gear 307 is arranged concentrically with the rotating rod 301. When the output end of the pneumatic push rod 304 pushes the push plate 305 out, the push plate 305 drives the gear 307 to rotate through the rack 306, thereby driving the rotating rod 301 to rotate.

[0037] In this embodiment, a traveling wheel 104 is rotatably installed at the bottom of the moving seat 102, and auxiliary wheel assemblies 105 are installed on both sides of the moving seat 102. The setting of the auxiliary wheel assembly 105 enables the device to maintain better balance. When laying the pipeline, the traveling wheel 104 and the auxiliary wheel assembly 105 are set on both sides of the pipeline laying tunnel, and move along the tunnel direction as the laying progresses.

[0038] Working principle: when the device is in use, the lifting plate 101 is first moved to the top of the pipeline laying tunnel, and the moving seats 102 on both sides are respectively located on both sides of the tunnel. In the initial state, the two moving rods 201 are far away from each other, and the staff moves the pipeline to be laid between the arc rods 401 and starts the motor 202. Due to the setting of the moving block 303 and the slide groove 106, the motor 202 drives the two moving rods 201 to approach each other through the bidirectional screw rod 203, and the moving rod 201 drives the rotating rods 301 on both sides to approach each other. The rotating rod 301 drives the arc rod 401 and the supporting seat 402 to approach each other through the connecting seat 302, so that the arc rod 401 is against the positions on both sides of the gas pipeline. At this time, the docking plate 405 on the supporting seat 402 docks into the slot 404, and then the staff slowly lowers the gas pipeline, so that the bottom of the gas pipeline drops to the position of the cushion block 403. At this time, the arc rod 401 and the cushion block 403 fully support the gas pipeline, and then the output end of the hydraulic cylinder 103 is retracted, and the lifting The descending plate 101 descends, and the supporting seat 402 and the gas pipeline descend accordingly, until the gas pipeline is completely descended into the laying tunnel, and the workers are waiting for the installation and laying work of the pipeline to be completed, and then the pneumatic push rod 304 is started. During the process of pushing the push plate 305 out by the output end of the pneumatic push rod 304, the push plate 305 drives the gear 307 to rotate through the rack 306, thereby driving the rotating rod 301 to rotate, and the rotating rod 301 drives the arc rod 401 to rotate through the connecting seat 302, and the arc rod 401, the supporting seat 402 and the cushion block 403 rotate relative to the gas pipeline until the direction of the end of the supporting seat 402 is parallel to the direction of the tunnel, and the output end of the hydraulic cylinder 103 is driven to extend, and the lifting plate 101 is raised, so that the rotating mechanism and the supporting mechanism are moved out of the tunnel, and then the device is moved to the next installation position, so that the moving rod 201, the rotating rod 301 and the arc rod 401 are reset, and the above operation is repeated. The device can reduce the width of the excavated tunnel and can provide a stable support effect for the laying of the gas pipeline.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
